Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a stamping device for an automobile engine cover. Background Art

[0002] Car hoods are usually made of rubber foam and aluminum foil. While reducing engine noise, they can also isolate the heat generated by the engine, effectively protecting the paint on the hood surface and preventing aging. Car hoods are usually made using stamping technology.

[0003] However, it still has the following disadvantages in actual use:

[0004] During the stamping production of the existing automobile hood, the upper mold plate is moved to fit with the lower mold plate, thereby stamping the automobile hood placed in the mold cavity. However, when the upper mold plate presses down the lower mold plate unevenly, the automobile hood will be stamped unevenly, affecting the product quality. Long-term uneven stamping will shorten the life of the lower mold plate.

[0005] Therefore, a new automobile hood punching device is proposed to solve the above problems. Utility Model Content

[0045] Protection component 2; the protection component 2 includes positioning holes 21 opened at the four corners of the upper end of the lower template 11, a telescopic spring 22 placed in the center of the positioning hole 21, a positioning column 23 connected to the four corners of the bottom end of the upper template 13, a hollow circular groove 24 opened in the inner position of the positioning column 23, and a pressure sensor 25 connected to the top position of the inner position of the positioning column 23;

[0046] The stamping assembly 1 further includes a die cavity 12 opened at an inner position of an upper end of the lower die plate 11 and a die block 14 connected to a bottom end of the upper die plate 13;

[0047] The positioning hole 21 is opened relative to the positioning column 23, and the length of the telescopic spring 22 is greater than the length of the positioning column 23;
