Locking plate forming mould

Abstract

The invention relates to a locking plate forming mould. The thickness of a locking plate is 1.5mm; the locking plate comprises a strip-shaped body part; an arc-shaped part extending to two sides is arranged in the middle of the body part; the length-width ratio of the locking plate is larger than 10; and the locking plate forming mould comprises a lower mould assembly formed by a lower mould plate, a lower base plate and a female die connected sequentially and fixedly, and an upper mould assembly formed by an upper mould plate, an upper base plate, an installation plate and a stripper plate connected sequentially. According to the locking plate forming mould provided by the invention, the stability in processing special-shaped parts is improved, the convenience in operation is realized, the process of routine maintenance and spare part replacement is simplified, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a mold for preparing locking pieces by a punching process. Background technique [0002] figure 1 It is a schematic diagram of the three-dimensional structure principle of a locking piece; figure 2 for figure 1 Schematic diagram of the structural principle of the locking plate. see figure 1 with figure 2 As shown, the locking piece 100 has a thickness of 1.5 mm and includes a strip-shaped body portion 101. The middle portion of the body portion 101 is provided with an arc-shaped portion 102 extending to both sides. The body portion has a width of 4 mm and a length of 44.2 mm. The diameter of the arc-shaped portion 102 is φ7.1 mm, and the connection between the arc-shaped portion 102 and the body portion 101 is a circular arc transition angle with a radius of 0.5 mm. Both ends of the body portion 101 are provided with 45° inverted horn. That is to say, the a...

AI Technical Summary

Problems solved by technology

[0003] Since the locking piece 100 is a slender strip-shaped structure with a relatively large aspect ratio, and the center circle (that is, the arc portion 102) and the shape and position accuracy of the overall shape are required to be high, the existing production process is continuously During the production process, the body part 101 is prone to warping, and the arc transition angle at the junction of the arc part 102 and the body part 101 is out of tolerance

In addition, since the locking plate 100 is in the shape of a long and thin strip, the rigidity and strength of the punch are limited, and it often needs to be replaced during use.
