A heat-resistant metal bellows mechanical seal cutting device with fixed function

Abstract

The invention discloses a cutting device for a heat-resistant metal bellows mechanical seal with a fixed function, which comprises a base and a first hydraulic cylinder. There is a mobile bracket, the upper side of the deflector is provided with a bearing frame, the first hydraulic cylinder is fixed on the inner top of the mobile bracket, and the lower side of the first hydraulic cylinder is connected to the main body of the cutting machine through the first piston rod , the right side of the upper end surface of the base is fixed with a fixed bracket, and the right end surface of the fixed bracket is fixed with a first hydraulic cylinder, the jacket sleeve is placed outside the right end of the limit rod, and the limit rod runs through the fixed bracket, the Both the upper and lower surfaces of the connecting block are provided with grooves, and electric telescopic columns are fixed in the grooves. In the heat-resistant metal bellows mechanical seal cutting device with a fixed function, the splint can move up and down under the rotation of the threaded column, which is convenient for clamping or loosening the heat-resistant metal bellows.

Description

technical field [0001] The invention relates to the technical field of bellows processing, in particular to a heat-resistant metal bellows mechanical seal cutting device with a fixing function. Background technique [0002] Bellows is a sealing element that integrates elastic elements, auxiliary seals and torque transmission mechanisms. Its torque mode is unique to bellows mechanical seals. Bellows mechanical seals have a wide range of applications, from low temperature to high temperature, From neutral medium to corrosive medium, from low speed to high speed, from ordinary to harsh working conditions, metal bellows can be used for mechanical seals of high temperature, high pressure and low temperature media, both as auxiliary seals and as For the elastic element, in order to obtain a heat-resistant metal bellows of a specified length, it is necessary to use a cutting device to cut the entire heat-resistant metal bellows. [0003] The existing cutting device is difficult to...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a heat-resistant metal bellows mechanical seal cutting device with a fixed function, so as to solve the problem that the existing cutting device proposed in the above background technology is difficult to cut the heat-resistant metal bellows. It is clamped and fixed, and in the process of clamping and loosening the heat-resistant metal bellows, the heat-resistant metal bellows is prone to displacement and affects the accuracy of the cutting length, and it is difficult to adjust the heat-resistant metal bellows. Multiple cutting processes, thus affecting the working efficiency of the device
