Description

Technical Field

[0001] The utility model belongs to the field of stamping part processing and positioning, and specifically relates to a stamping part processing and positioning device. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. Stamping and forging are both plastic processing or pressure processing, collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips.

[0003] A Chinese patent with application number CN202320762442.4 discloses a local processing positioning device for stamping parts, so that when clamping a special-shaped workpiece, the clamping plate can form a certain angle so that it can better fit the special-shaped workpiece and achieve more stable positioning and clamping. By setting a pin and a torsion spring, the clamping plate can automatically rebound and restore to its original position after the clamping is cancelled, which is convenient for the next clamping. By setting an upper clamping member, the special-shaped workpiece can be positioned and clamped in the vertical direction. The local processing positioning device for stamping parts in this application positions the workpiece by elastically rotating the clamping plate. After positioning, the stability is low. During the stamping process, the workpiece is prone to horizontal displacement. Although the elastic downward pressure of the upper clamp on the workpiece can enhance a certain stability, it is still easy to cause horizontal displacement of the workpiece.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0009] Optionally, a hole is provided on the sliding plate, and the two clamps are elastically rotatably fitted in the hole. A rotating handle corresponding to the clamp is rotatably fitted on the sliding plate. One end of the rotating handle extends into the hole and is connected to the clamp.

[0010] Optionally, a smooth curved surface is provided on the outer side of one end of the threaded pull rod, a first bearing is sleeved on one end of the threaded pull rod, the worm gear is fixedly sleeved on the first bearing, and a second torsion spring connected to the worm gear is fixedly sleeved on the threaded pull rod, so that the worm gear drives the threaded pull rod through the second torsion spring and then drives the threaded tube to slide, so that when one of the threaded tubes presses against the clamping plate, the worm continues to rotate, presses against the second torsion spring corresponding to the clamping plate to store elastic force, and the other threaded tube continues to move, so as to facilitate the positioning of the two clamping plates rotated at different angles.

[0011] Optionally, second bearings corresponding to the threaded rod are embedded on both sides of the U-shaped frame, and one end of the threaded rod is fixed in the second bearing, so as to improve the rotation stability of the threaded rod through the second bearing.
