Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, in particular to a stamping forming device for processing automobile parts. Background Art

[0002] When processing some metal auto parts, stamping equipment is used for stamping. The stamping device uses a mold to apply pressure to the metal sheet under the action of a press to cause it to undergo plastic deformation, thereby obtaining the desired shape and size of the auto parts.

[0003] For example, publication number: CN109226423B "A stamping and forming device for new energy vehicle parts" includes a workbench, a left support plate, a right support plate, a top plate, a hydraulic cylinder, a hydraulic rod, a mounting plate, a pull rod, two sets of first limit rods, two sets of second limit rods, a stamping upper die, a slide, a slide plate, a stamping lower die, a first limit plate and, a first spring, a second limit plate and a second spring, and also includes a left adjustment plate, a right adjustment plate, a left magnet plate, a right magnet plate, two sets of left locking screws, two sets of right locking screws, two sets of left locking nuts, two sets of right locking nuts, two sets of left sliders, two sets of right sliders, a top rod, a third limit plate and a third spring.

[0004] However, in the prior art, when continuous stamping forming equipment is used for stamping processing, the stamping equipment will generate continuous and strong vibrations when working. The crank slider mechanism of the press will vibrate due to the inertia force during high-speed reciprocating motion. This vibration will be transmitted to the feeding device and the positioning device. Continuous feeding operations are performed in a vibrating environment, causing the sheet material being fed to shake, resulting in inaccurate positioning. The impact of vibration is more obvious in particular for thin sheets. When processing some automotive parts with high requirements for position accuracy, inaccurate feeding and positioning may cause the parts to be unable to be assembled correctly.

After the material is stamped, the No. 1 cylinder inside the front end slide rail pushes the slider to move again, and the material is fed through the No. 1 and No. 2 clamping plates at the front end, thereby improving the feeding efficiency.

[0018] 3. In the present invention, the position of the limit plate is adjusted by rotating the adjusting bolt, so that the limit plate limits the stability of both sides of the material.
