Cutting device for mechanical seal of heat-resistant metal bellow and with fixing function

Abstract

The invention discloses a cutting device for a mechanical seal of a heat-resistant metal bellow and with a fixing function. The cutting device comprises a base and a first hydraulic cylinder, a flow-guiding channel is formed in the base, the rear side of the upper end face of the base is slidably connected with a movable support, a bearing frame is arranged on the upper side of a flow-guiding plate, the first hydraulic cylinder is fixed to the inner top of the movable support, the lower side of the first hydraulic cylinder is connected with a cutting machine body through a first piston rod, afixed support is fixed to the right side of the upper end face of the base, the first hydraulic cylinder is fixed to the right end face of the fixed support, a clamping sleeve is placed on the outer side of the right end of a limiting rod in a sleeving mode, the limiting rod penetrates through the fixed support, grooves are formed in the upper surface and the lower surface of a connecting block correspondingly, and electric telescopic columns are fixed into the grooves. According to the cutting device for the mechanical seal of the heat-resistant metal bellow and with the fixing function, clamping plates can move up and down under the rotation effect of a threaded column, and thus the heat-resistant metal bellow is convenient to clamp or loosen.

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
