Description

Technical Field

[0001] The utility model belongs to the field of stamping devices, and in particular relates to a stamping device suitable for processing parts of different sizes. Background Art

[0002] The stamping machine drives the flywheel through an electric motor, and through the clutch and transmission gear, drives the crank-connecting rod mechanism to move the slider up and down, driving the stretching die to form the steel plate. The so-called double-action means that the press has two sliders, divided into an inner slider and an outer slider. The inner slider drives the punch or die of the die, and the outer slider drives the blank holder on the die. When stretching, the blank holder first moves to press the edge of the steel plate, and then the inner slider moves to stretch. The stamping machine must be used in the production process of automotive parts.

[0003] A Chinese patent with application number CN202220371129.3 discloses a stamping device for automotive parts of different sizes. By activating a first clamping assembly and a second clamping assembly for clamping and limiting, the problem that most stamping dies of existing automotive parts stamping machines are only suitable for processing automotive parts of the same size in order to ensure the stamping quality when stamping raw materials is solved. The inner wall of the protective groove is used for protection to prevent the parts from being pressed and dislocated and popping out of the surface of the workbench, and the anti-slip convex strips are used to increase the clamping limiting capacity. In this application, the two clamping assemblies are used for clamping, and the second clamping assembly needs to be horizontally positioned before the first clamping assembly is used for vertical positioning. The sum of the positioning time required for the second clamping assembly and the first clamping assembly is greater than the time required for a single positioning clamping assembly. The positioning time is long, which affects the processing efficiency.

[0004] In view of this, the present utility model is proposed. Summary of the invention
