Problems solved by technology

[0003] Sheet metal processing methods include: shearing, punching, grinding, bending, stretching, and forming. Among them, punching is to use punching equipment to punch out the required holes on the metal sheet. Today's punching equipment can only Simply complete the punching operation, and the inner wall of the hole cannot be polished in real time after the punching is completed. Therefore, it is often necessary to spend time grinding the opened holes after the punching is completed, which greatly reduces the efficiency of sheet metal processing. , to this end, we propose a sheet metal processing method based on punching potential energy to automatically polish holes to solve the above problems

Embodiment 1

[0032] Such as Figure 1-5 As shown, a sheet metal processing method for automatically grinding holes based on punching potential energy mainly includes the following steps:

[0033] S1 cutting, cutting the metal sheet to the required size through the shearing machine;

[0034] S2 punching, through the punching equipment to punch out the required holes on the plate obtained in S1;

[0035] S3 bending, bending the plate punched by S2 through a bending machine to obtain the plate that needs to be bent;

[0036] S4 stretching, stretching the plate obtained in S3 into the desired shape through stretching equipment;

[0037] S5 forming, placing the plate obtained in S4 on the punching machine, and shaping it into the desired product through the mold;

[0038] The punching equipment used in the above sheet metal processing process includes a box body 1, a bracket 2 is fixedly connected to the box body 1, and a puncher 3 is arranged on the bracket 2, a metal sheet 4 is placed on t...

Embodiment 2

[0043] Such as Image 6 As shown, the difference between this embodiment and Embodiment 1 is that: a piston chamber 17 is provided in the box body 1, and a piston 18 is slidably connected to the piston chamber 17, a magnetic rod 19 is fixedly connected to the support block 6, and the magnetic The end of the rod 19 away from the support block 6 is slidingly connected to the side wall of the piston chamber 17, the magnetic rod 19 is attracted to the sliding end on one side of the piston 18, the piston chamber 17 is connected with a suction pipe 20, and the suction pipe 20 is arranged through the casing 1, The piston chamber 17 is fixedly connected with a filter screen 21, and the filter screen 21 is made of a magnetic material. The feed inlet of the suction pipe 20 is a tapered design, and the suction pipe 20 is provided with a one-way valve 22. The cone of the suction pipe 20 feed inlet Shaped design can enhance the airflow pressure during the suction process and improve the me...

Abstract

The invention belongs to the field of sheet metal machining and particularly relates to a sheet metal machining method for automatically polishing a hole based on punching potential energy. The methodmainly comprises the steps of shearing, punching, bending, stretching and forming. Punching equipment used in the sheet metal machining process comprises a box, wherein a support is fixedly connectedto the box, a puncher is arranged on the support, and a metal plate is placed on the box. According to the method, through cooperation of a polishing rod and a compression spring, the press-down potential energy of the puncher can be accumulated in the compression spring; after punching is completed, the reactive force of the compression spring is utilized to drive the polishing rod to ascend; and under the transmission action of a worm and a worm gear, rotation of the polishing rod is realized, the polishing rod can polish the inner wall of the hole in the process of penetrating through thehole, waste of time in late polishing is avoided, and sheet metal machining efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of sheet metal processing, in particular to a sheet metal processing method for automatically grinding holes based on punching potential energy. Background technique [0002] Sheet metal is a processing technology. Sheet metal is a comprehensive cold processing process for metal sheets.
