Production and manufacturing method for flange connection metal gasket

Abstract

The invention provides a production and manufacturing method for a flange connection metal gasket. The production and manufacturing of the metal gasket are completed through cooperating a supporting frame, an auxiliary device, a stamping device and the like; the main following existing problems in the current metal gasket production process are solved: a, a round hole in the middle of the metal gasket shakes and deflects during the punching and rotary cutting process, so the size of the internal round hole of the manufactured metal gasket is irregular, the metal gasket is affected to be sleeved on the flange, so the connection strength of the flange and the part is reduced; b, when the round hole in the middle of the metal gasket is produced by a rotary cutting method, the remaining metalmaterial produced on the metal gasket remains in the interior of a rotary cutter, so the residual material blocks the rotary cutter after long-term use, the rotary cutting work cannot be performed normally, the residual metal material in the rotary cutter needs to be taken out manually, but the remaining material in the rotary cutter is difficult to be taken out manually, and a lot of working timeis required.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and manufacturing, in particular to a method for manufacturing flanged metal gaskets. Background technique [0002] When the flange is connected with external parts; usually in order to improve the connection strength between the flange and the parts, it is necessary to set a metal gasket between the flange and the parts, and to improve the connection strength through the metal gasket; the metal gasket Most of the production is completed by stamping, but the existing production process of metal gaskets mainly has the following problems: [0003] a: The round hole in the middle of the metal gasket will shake and deflect during the stamping and rotary cutting process, resulting in the irregular size of the inner round hole of the manufactured metal gasket, which will affect the fitting of the metal gasket on the flange, making the flange The connection strength with the parts is reduc...

AI Technical Summary

Problems solved by technology

[0003] a: The round hole in the middle of the metal gasket will shake and deflect during the stamping and rotary cutting process, resulting in the irregular size of the inner round hole of the manufactured metal gasket, which will affect the fitting of the metal gasket on the flange, making the flange The connection strength with the parts is reduced; b: When the middle hole of the metal gasket is produced by rotary cutting, the metal residue produced on the metal gasket remains inside the rotary cutting ring knife, making the residue after long-term use The rotary cutting ring knife is blocked, so that the rotary cutting work cannot be carried out normally. It is necessary to manually remove the metal remaining material inside the rotary cutting ring knife, but it is difficult to manually remove the remaining material inside, and it takes a lot of working time for workers
