[a]https%3A%2F%2Fwww.boyamachinery.com%2Fproducts%2Frewinding-line%2F[/a] <br>#tension #leveler <br>Rewinding/ recoiling lines will encounter the problem of strip skidding during the actual usage which can lead to production barriers like strip deviation, at the meantime, coil processing lines can affect the security of production equipment. With the pressure roller, tension rolls for the rewinding unit can prevent the strip from slipping on the surface of the rolls and get initial tension. <br> <br>BOYA Rewinding Line Features <br> <br>The force increase of tension roller unit was achieved by wrapping effect of each tension roll. <br> <br>In the condition of the rewinding line wrapped around a roll was affected by a certain initial tension, the friction force between them reached a maximum number and the transfer power outreached the maximum friction, there will be skidding between the strip of recoiling line and the roll surface. <br> <br>Automatic Sleeve Feeding arrangement system. <br> <br>Entry Flattener with Quick Opening Feature. <br> <br>Doctor blade to be provided for all entry/exit deflector rolls, bridle rolls, and turn rolls. <br> <br>The Coil car will have auto coil shuffling to move the coils up to saddle one. <br> <br>Full line canopy covers. <br> <br>The Belt Wrapper is designed in such a way that it will be suitable for under and recoiled. <br> <br>Tinplate and Carbon Steel. <br> <br>Trimming Speed: 720Mpm Leveling Speed: 600Mpm <br> <br>Rewinding Line Strengths <br> <br>The coil car will be lifted up to the collapsed mandrel So that we can easily unload small coils from the mandrel. <br> <br>Low pressure system to prevent damage when removing small coils. <br> <br>Improve the flatter efficiency. <br> <br>High precision and stable control system. <br> <br>Safety and reliable production process. <br> <br>Compact structure and easy maintenance, environmental protection. <br> <br>Rewinding Line Working Principle <br>01 <br>The recoiling line running speed also can affect the total friction between the strip and the roll surface. When the strip runs under a higher speed, the positive pressure of the strip on the roll surface is lower, and the gas passing between strip and roll surface in the entrance cannot be exited quickly, which can continue to accumulate with the increase of speed. Therefore, on the one hand, the actual wrap angle between the strip and the roll surface is reduced, on the other hand, the coefficient of friction between them is also diminished. Finally, all of them results in the decrease of the whole friction, which can be represent apparently under the poor incoming plate shape. In conditions of the same initial tension of tension roller unit, the entrance roller unit with a small force has a higher slip probability than the exit one with a higher force. <br> <br>02 <br>The slipping of any tension roll unit will cause scratches to the surface of the strip. In the rewinding line, the light damage can degrade product quality, while the heavy one will scrap the strip. So the slipping of the tension roll unit is extremely harmful to production. <br> <br>03 <br>At the same time, the slipping of any tension roll unit will have a direct effect on itself, which can make the roller surface smoother and smoother. The friction coefficient diminished rapidly, so we need to regrind the roll surface and the roll usage period will be shorted. In addition, the skidding of tension roller unit can cause motor output torque to fluctuate, impact the transfer decelerator, make gear failure and defect the decelerator. <br> <br>04 <br>In order to prevent slipping, rewinding line diameter is selected based on the principle that no plastic deformation occurs after the strip passed through the tension roller. The max thickness of coil processing line strip is the main factor to determine the max diameter of tension roller. The phenomenon that the slipping probability of cold-rolled thin strip steel is significantly increased under the large tension roll diameter. There should be a limit to the adaptation scope of strip, the diameter of tension roller is not the bigger the better. In order to add the friction coefficient as soon as possible, we need to increase the roughness of the roll surface. <br> <br>05 <br>Although we cannot eliminate the slipping of tension roll through the way of improve the electrical control of tension roller unit, we can provide the reasonable and perfect electrical control method which can benefit to diminish the degree of slippage. Therefore, we can decrease the wear of tension roll, and it is helpful for us to find and correct the slipping. <br> <br>If you want to know more details of stainless steel coil processing, please visit our website. <br> <br>Now the price of tension leveler is reasonable, if you are interested, please contact us.

Click on the links below for more information! <br> <br>What is Metal Leveler Machine? <br>The so-called straightening machine sheet leveler machine is simply equipment for straightening metal profiles, bars, pipes, wires, etc. The working principle of this kind of metal forming machine is to change the straightness of bars etc. through the straightening rollers. Generally speaking, the leveler machine has two rows of straightening rollers, of course there are exceptions. The two-roll leveler machine usually straightens materials of different diameters by relying on the angle change of the two rolls. leveler machines can be divided into pressure leveler machines, balanced roll leveler machines, shoe roll leveler machines, rotary reverse bending leveler machines and so on. <br> <br>Straightening Process of Sheet Leveler Machine <br> <br>When the sheet leveler machine is working, the position of its rollers is at a certain angle with the direction of movement of the product to be straightened. Two or three large ones are active pressure rollers, which are driven by the motor to rotate in the same direction. Several small rollers on the other side are The driven pressure rollers are rotated by the friction of the rotating rod or tube. In order to achieve the required compression of the product by the rollers, these small rollers can be adjusted forward or backward at the same time or respectively. Generally, the more the number of rollers, the higher the accuracy of the product after straightening by sheet leveller. After the product is bitten by the roller, it continuously moves in a straight line or rotates, so that the product undergoes various deformations such as compression, bending, and flattening, and finally achieves the purpose of straightening. <br> <br>Why Choose BOYA Metal Sheet Leveler Machine <br>The metal straightener from Boya is well designed and strong enough to be used in countless manufacturing industries.

BOYA uses special work roll material to produce sheet metal roller used in tension leveler of pickling line. These work roll are applied to many industrial giant and their working performance is as good as the original. <br> <br>Details of Work Roll <br> <br>In steel rolling, the work roll service is in direct contact with the strip to produce deformation and finally get the roller of the product. The active roll driven by the motor is the work roll. In the manufacture of thin sheet metal roll, the metallurgical quality of the sheet metal roller design should be strictly controlled or supplemented by external measures to enhance the bearing capacity of the roll. Reasonable roll shape, hole shape, deformation system and rolling conditions can also reduce the working load of rolls, avoid local peak stress and prolong work roll chock life. The consumption of work roll depends on three factors: <br> <br>Rolling mill, material and rolling condition, and the reasonable choice of roll; <br>Work roll material and manufacturing quality; <br>Roll use and maintenance system. <br> <br>There are many sheet metal roller manufacturers, but we are one of the best choices for you. <br> <br>For more information about sheet metal coil processing and tension leveller, please feel free to contact us! <br>#sheet#metal#roller#suppliers <br>[a]https%3A%2F%2Fwww.boyamachinery.com%2Fproducts%2Fwork-roll%2F[/a]

Including strong blanking precision blanking, precision blanking to concave die and flat blanking precision blanking. Automotive precision punching parts production to strong blanking precision blanking. The geometric shape, dimensional tolerance, shape and position tolerance and shear surface quality of fine blanking parts are much higher than ordinary blanking parts, fine blanking process plays a great role in the field of automotive parts manufacturing. <br> <br>Working Principle of Fine Blanking <br> <br>Compared to normal blanking, fine blanking operation is more precious, product high precision requirements, no collapse Angle, no burr, the full bright belt is the difficulty of stamping process, the use of ordinary blanking process cannot avoid burr, collapse angle. <br> <br>Fine blanking technology is a special method to solve this kind of product. <br> <br>Fine Blanking Advantages <br>Fine blanking china is a kind of chipping-free processing technology, which is a precision blanking method developed from the general blanking technology. Fine blanking ensures that the punched surface of the punched part is free of cracks and tears over its entire material thickness. In addition, the tightest dimensional accuracy and flatness tolerances can be achieved. Fine blanking is able to obtain high quality fine blanked parts with higher dimensional accuracy, cleaner blanking surface, less warpage and better interchangeability than normal blanked parts in one punching stroke, and to achieve improved product quality at a lower cost. <br> <br>Fine Blanking Process <br>There is a fundamental difference between the process characteristics of fine blanking and normal blanking. While normal blanking controls the tearing of the sheet during the blanking process, fine blanking does everything possible to inhibit the tearing of the sheet during the blanking process. Fine blanking design remains as one piece until the part is separated from the sheet, and the sheet metal is always in a plastic deformation process during fine blanking. To achieve this, the V-rim and counterpress are used to hold the sheet before punching to prevent the sheet from moving inside or outside during the punching process. In addition, together with the small gap between the convex and concave dies and the appropriate small rounded corners of the concave die, a three-way compressive stress state in the local area of the punching is formed during the punching process, thus ensuring the plastic deformation process of the punching. Moreover, the fine blanking material and lubrication state also have a great influence on the effect of fine blanking operation. The material with good plasticity, low deformation resistance, complete spheroidization, good dispersion and uniform distribution of fine spherical carbide organization is most suitable for fine blanking. A good lubricant not only improves the quality of the fine blanked parts, but also helps to reduce the wear of the die and improve the service life of the die. The fine blanking process requires precise punching force, crimping force and counter pressure of the fine blanking equipment. <br> <br>Fine Blanking Applications <br>Fine blanking technology can be applied to various applications such as automobile, motorcycle, computer, video recorder, communication equipment, aircraft manufacturing, home appliances, office machinery, optical components, and construction industry etc. There are nearly 8000 kinds of parts produced by fine blanking, about 50%~60% of fine blanking parts are used in automobile industry, such as rack, tooth plate, cam on seat adjuster; ratchet, pawl, adjusting tooth plate, pull arm, push rod, web, support plate, etc. in brake system; lock plate, card plate, safety block, etc. in car lock; latch, inner gear ring, pawl, etc. in seat belt; follower plate, etc. in clutch; transmission Fork, etc.; transmission system flange, thrust gasket, etc.; door glass lifter gear plate, etc. Many of the stamped parts on these automobiles are produced by the fine blanking process. Boya is one of the leading fine blanking companies and fine blanking suppliers in China and we can offer a complete fine blanking services and solutions to our customers. <br> <br>Fine Blanking VS Stamping <br>Fine blanking originated from general stamping, but it is not simply an enhanced version of general stamping. The essential difference between the fine blanking process and the general blanking process is that the general blanking cannot effectively avoid the generation of tears in the section when punching, while the fine blanking tries to inhibit the occurrence of tears in the sheet material by all means when punching. The following are the differences between fine blanking and general stamping. <br> <br>1. Difference in requirements of materials to be processed <br>Ordinary stamping can process almost any material, as long as the die steel is strong enough and the press pressure is sufficient. <br> <br>However, the materials used for fine blanking require good plasticity, low flexural strength ratio and high elongation of the material to be processed because of the need to effectively transfer compressive stress between material crystals to inhibit cracking. <br> <br>2. Differences in processing capacity characteristics <br>General punching limit size <br> <br>Stamping: Minimum hole diameter of 1.5 times the material thickness. <br> <br>Fine blanking: minimum hole diameter up to 0.6 times the material thickness. <br> <br>Dimensional accuracy <br> <br>Stamping: Normal dimensional accuracy, IT14. <br> <br>Fine blanking: High dimensional accuracy, IT6~9. <br> <br>Cold work hardening <br> <br>Stamping: partial cold work hardening of section collapse and bright zone. <br> <br>Fine blanking: cold hardening of the whole section, which can improve the strength of the contact surface. 4. <br> <br>3. Difference in equipment used <br>Ordinary stamping equipment generally provides one-way power (there are also double power presses to process special-shaped products), i.e. punching force. However, fine blanking operation machines can provide three power forces, punching force, crimping force and counter-top force. And the fine blanking press is compact and has a small table surface. The table length of fine blanking machines of about 800T is generally about 1m. Of course, like ordinary stamping machines, fine blanking machines also need other supporting auxiliary equipment. The necessary auxiliary systems for general fine blanking machines are uncoiling and leveling feeder, die lubrication system and parts waste separation system. <br> <br>For more information about coil processing lines and cut to length machine, please feel free to contact us! <br>#fine#blanking#design <br>[a]https%3A%2F%2Fwww.boyamachinery.com%2Fproducts%2Ffine-blanking%2F%0A%0A%0A%0A%0A%0A%0A[/a]
