Description

Technical Field

[0001] The utility model belongs to the technical field of stamping, in particular to a stamping device for processing automobile precision parts. Background Art

[0002] Stamping is a forming process that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) 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] In the existing device, during the actual stamping process, the material to be stamped is extruded and formed, and some small waste materials are prone to splashing. The stamping device does not have the function of shielding and preventing splashing, which poses certain safety hazards and reduces the practicality of the stamping device. At the same time, after long-term use, the lower mold is more easily damaged than the upper mold due to excessive downward pressure and long working time. Therefore, a stamping device for processing automotive precision parts is proposed. Summary of the Invention

[0010] The utility model has the following beneficial effects:

[0011] The utility model starts the first double-headed motor to drive the second bevel gear to rotate, and the second bevel gear meshes with the first bevel gear to rotate the lifting screw, and the lifting screw drives the baffle to move up and down through the sliding sleeve, thereby protecting the stamping area, avoiding small waste from splashing, reducing safety hazards, and improving the practicality of the stamping device; at the same time, the second double-headed motor is started to drive the fourth bevel gear to rotate, and the fourth bevel gear meshes with the third bevel gear to drive the reciprocating screw to rotate, and the reciprocating screw cooperates with the slider thread, so that the two sets of sliders drive the clamping plates to clamp in opposite directions, thereby clamping plates of different sizes.

[0012] When the lower template is damaged, press the lower pressure column to push the lower pressure block downward. Since the inclined surface of the lower pressure block fits the inclined surface of the limit block, the lower pressure block causes the limit block to retract into the movable groove during the downward pressure process. At this time, another staff member removes the lower template to complete the disassembly. During installation, you only need to align the insert block with the card slot. After alignment, press the lower template downward to force the inclined surface of the limit block to retract into the movable groove. When the position of the limit slot is aligned with the position of the movable slot, the limit block is bounced into the limit slot by the first spring to achieve installation and fixation.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
