Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipe caps, in particular to a pipe cap punching die which is able to prevent demoulding damage. Background Art
[0002] The pipe cap is also called the end cap. The end cap refers to the component used to seal the end of the container to isolate the internal and external media. It is also called the end cover. The end cap of a cylindrical container is generally a rotating shell. According to the shape of the end cap surface, it can be divided into convex, conical, flat and combined shapes. A convex end cap refers to a end cap with a convex outer surface, such as a hemispherical, elliptical, dish-shaped and spherical end cap without folded edges. Some gas cylinders use a combined bottom end cap with the convex surface inward, which can not only ensure strength but also meet the needs of safe use. However, molds are required for the production of pipe caps.
[0003] In the current production of pipe caps, the temperature of the pipe caps is high after production in the mold, which easily causes the workpiece to adhere to the inner wall of the mold, which is not only inconvenient for demoulding, but also easily causes damage to the workpiece, thereby causing additional losses.
[0004] Therefore, it is necessary to provide a new tube cap punching die that prevents demoulding damage to solve the above technical problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:
