Common Problems and Treatment Methods of Sheet Metal Processing Bending in


Dongguan sheet metal processing bending common problems and treatment methods:
In Dongguan sheet metal processing bending process, often encounter many problems, understand these common problems and their handling methods, you can meet the problems encountered in the subsequent bending to provide a solution to achieve rapid and efficient production of the first A. Problem: After bending the workpiece deformation at the bend.
B. Cause: the deformation is mainly due to the bending speed, and the hand did not keep up with the speed of the workpiece caused by bending
C. Solution: reduce the bending speed, hand-held workpiece and the workpiece at the same time.
Second, a. Problem point: bending a long workpiece, there will be a big angle, a small
B. This situation, generally have the following circumstances:
(1) material thickness is inconsistent, one end thick side thin
(2) mold wear uneven, different height at both ends
(3) the middle block is not balanced, not at the same level
C. Solution:
(1) feedback to the laser or NCT, let it pay attention to the election material
(2) tool change mode
(3) adjust the middle block
Third, a. Question: Some bending parts will be deformed when bending   B. Causes: the occurrence of this situation is mainly due to the C for the post-fixed positioning, bending B, the workpiece bending up the movement, hit the post-regulation, was fixed after the rule. After bending, D It was squeezed deformation.
C. Solution: After the use of post-regulation function.
Fourth, a. Question: Bend size is small, bad positioning, the mold is easy to pressure after the regulation.
B. Cause: Because t = 0.8, press the mold selection principle, v = 5 × 0.8 = 4mm.4v center to edge distance of 3.5mm, and 2.9mm within the size of 2.9-0.8 = 2.1mm, bending size In the v center line to the edge of the distance, when the dress can not be positioned. Using the next mold anti-loaded, the model will be pressed after the regulation, positive and negative equipment will not work, to other methods.
C. Solution: 1, can be installed under the mold. In the post-regulation before adding a gasket (not more than 3t), so that after the regular regulation back, to avoid the upper mold, 2, if the other end of the size ≧ 3, can also be the other end by bit,
