Stamping die for heat exchanger sealing gasket production

Abstract

The invention discloses a stamping die for heat exchanger sealing gasket production, belongs to the technical field of stamping, and aims to solve the problem that part of sealing gaskets possibly need to be stamped for multiple times due to special shapes. A hydraulic press extends out to enable a first shell to be close to a stamping shell, the outer edge shape of a sealing gasket is cut when the first shell sleeves the outer wall of the stamping shell to move, and along with continuous extension of the hydraulic press, an L-shaped rod extrudes one end of a rotating rod to enable a top block to extrude a connecting plate; the size of a spring at the rear end of a first top plate is larger than the size of a spring at the rear end of a second top plate, the size of a spring at the rear end of a second movable plate and the size of a spring at the rear end of a third movable plate. According to the sealing gasket cutting device, the sealing gasket can be cut inside and outside at the same time through one-time punching, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a stamping die for producing a heat exchanger gasket. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. Heat exchangers are widely used as heaters, coolers, condensers, evaporators and reboilers. [0003] The gasket in the heat exchanger is generally formed by stamping in the production process. During the production process, the outer edge needs to be stamped. After the first stamping is completed, a second stamping is required to hollow out the interior, and some gaskets need to be stamped. Due to its special shape, multiple stamping may be required, and the operation is cumbersome. In addition, the existing gasket raw materials are mostly wound through rolls, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a stamping die for the production of heat exchanger gaskets, which solves the problem that the gaskets in heat exchangers in the background technology are usually formed by stamping during production, and the outer edge of the gasket needs to be aligned during the production process. For stamping, after the first stamping is completed, a second stamping is required to hollow out the interior. Due to its special shape, some gaskets may need to be stamped multiple times. The operation is more cumbersome, and the existing gasket raw materials are mostly passed through the roll. Rolling is carried out, and the material is discharged through the rotation of the roll during the unloading process. The speed of the unwinding is not constant enough, which is easy to cause waste of raw materials. In addition, after the stamping is completed, in order to avoid the leftovers from affecting the next step of stamping, it is necessary to set up a separate collection. The problem that the roll equipment rolls up the remaining leftover materials
