Problems solved by technology

The difficulty in forming it is that the protruding nozzle 21, the three-dimensional inner edge 42, the notch 31 and the perforation 32 all have angle requirements, but in the manufacturing process, the product must be processed in multiple steps from the structure of the rotating body, and the angle positioning is inconvenient; The formed asymmetric structure as the positioning basis of the subsequent process will bring new deformation or damage to the surface, affecting the quality of the feature structure

Embodiment

[0037] A method for forming a complex cylindrical part of the present invention, the steps include:

[0038] ①Take the edge of the blank as the reference plane, and form a covered ring-shaped step structure in the middle of the reference plane by multiple stretching methods. The covered ring-shaped step structure includes the bottom edge part 3 connected to the reference plane in turn. The cylindrical part 1 whose outer diameter is smaller than the bottom edge part and the top cover 4' connected to the end of the cylindrical part 1. For cylindrical products with a large stretching length, deep drawing is a relatively conventional technology, and the purpose is to prevent the product from being damaged by too much stretching at one time, so I won’t repeat it here. Using the prior art can form a covered ring-shaped step structure by tapering and elongating punches, because the peripheral portion of the top cover 4' needs to be processed before forming the special-shaped hole 41,...

Abstract

The invention belongs to the technical field of stamping processing, and relates to a method for forming complex cylindrical parts. The inner wall of the bottom edge is used as the positioning basis, and the outer edge is partially cut, leaving at least one process protrusion connected to the bottom edge, and the process protrusion is used as the positioning basis for shaping, punching and side cutting. This method allows the unique part of the complex cylindrical part to be formed with high precision by leaving a process protrusion at the position of the expected forming gap, avoiding material scars and ensuring product quality.

Description

technical field [0001] The invention relates to the technical field of stamping processing, in particular to a method for forming complex cylindrical parts. Background technique [0002] Metal stamping is a common process for processing many metal products. With the diversification of customer needs, the design of molds must also respond to various product needs. figure 1 What is shown is a complex cylindrical part with a structure similar to a rotating body, which includes a cylindrical part 1 located in the middle, an overlapping material part 2 located at the upper end of the cylindrical part 1, and a bottom edge part 3 located at the lower end of the cylindrical part 1 Together with the annular portion 4 located in the middle of the overlapping material portion 2, the cylindrical portion 1, the overlapping material portion 2, the bottom edge portion 3 and the annular portion 4 generally form a circular structure. Moreover, the outer diameter of the overlapping material ...
