Abstract
The invention discloses a rapid stamping process of a base, wherein the base comprises a body part, a boss, a groove, a through hole, a first extension part and a second extension part.
Description
Technical Field
The invention relates to a rapid stamping process of a base.
Background
When a workpiece with a complicated structure is processed by a stamping method, a plurality of stamping and stretching steps are required to obtain the required workpiece structure.
The utility model provides a base, it need process boss, recess in proper order, punch a hole, plastic side cut and buckle five process steps when processing, and current processing mode step is comparatively loaded down with trivial details to cause the lower technical problem of production efficiency.
Disclosure of Invention
The invention aims to provide a rapid stamping process of a base.
In order to achieve the purpose, the invention adopts the technical scheme that:
a rapid stamping process of a base, wherein the base comprises a rectangular body part, a circular arc-shaped boss which is positioned in the middle of the body part and protrudes upwards, an annular groove which is recessed downwards and concentrically arranged at the periphery of the boss, circular through holes which are arranged at four corners of the body part, an annular first extending part which extends upwards from the through holes, and a second extending part which extends upwards from four edges of the body part, the stamping process comprises the following steps:
the method comprises the following steps: stretching the flat plate on a stamping and stretching device in a positive and negative direction to form the boss and the groove;
step two: punching the through hole by adopting a punching device and simultaneously punching and shaping the edge part of the flat plate;
step three: and drawing the through hole upwards by adopting a stamping and drawing device to form a first extending part, and bending the edge part of the flat plate upwards to form a second extending part.
Preferably, the flat plate in the first step is a rectangular metal plate.
Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:
the invention combines the steps of stretching the boss and stretching the groove into one step, and completes the steps of punching and shaping and trimming through one stamping die, thereby saving the working procedure, shortening the processing time of the base workpiece and improving the processing efficiency.
Drawings
FIG. 1 is a front view of the plate after step one;
FIG. 2 is a top plan view of the plate after step one;
FIG. 3 is a top view of the plate after step two.
In the above drawings: 1. a body portion; 2. a boss; 3. a groove; 4. a through hole; 5. a first extension portion; 6. a second extension portion.
Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings to which:
referring to fig. 1, a rapid stamping process for a base, the base includes a rectangular body 1, a circular arc boss 2 protruding upwards from the middle of the body 1, a circular groove 3 recessed downwards and concentrically arranged on the outer periphery of the boss 2, circular through holes 4 arranged at four corners of the body 1, a circular first extending portion 5 extending upwards from the through holes 4, and a second extending portion 6 extending upwards from four edges of the body 1, the stamping process includes the following steps:
the method comprises the following steps: stretching a rectangular metal flat plate on a stamping and stretching device in a positive and negative direction to form the boss 2 and the groove 3;
step two: punching the through hole 4 by adopting a punching device and simultaneously punching and shaping the edge part of the flat plate;
step three: and (3) upwards drawing the through hole 4 by using a stamping and drawing device to form a first extension part 5, and upwards bending the edge part of the flat plate to form a second extension part 6.
In the embodiment, the original five processing steps are simplified into three processing steps, so that the processing time can be saved by 40%, and the production efficiency is improved.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
Claims (2)
1. A rapid stamping process of a base, wherein the base comprises a rectangular body part, a circular arc-shaped boss, a downward concave concentric ring and an annular groove, the circular arc-shaped boss is positioned in the middle of the body part and protrudes upwards, the annular groove is arranged on the periphery of the boss, the circular through holes are arranged at four corners of the body part, an annular first extending part extends upwards from the through holes, and second extending parts extend upwards from four edges of the body part, and the rapid stamping process is characterized by comprising the following steps:
the method comprises the following steps: stretching the flat plate on a stamping and stretching device in a positive and negative direction to form the boss and the groove;
step two: punching the through hole by adopting a punching device and simultaneously punching and shaping the edge part of the flat plate;
step three: and drawing the through hole upwards by adopting a stamping and drawing device to form a first extending part, and bending the edge part of the flat plate upwards to form a second extending part.
2. The rapid stamping process for a base as claimed in claim 1, wherein: the flat plate in the first step is a rectangular metal plate.
