Semi-automatic assembling tool for reducing flange of fuel gas corrugated pipe

Abstract

The invention relates to the field of processing of corrugated pipes, in particular to a semi-automatic assembling tool for a reducing flange of a fuel gas corrugated pipe. The semi-automatic assembling tool comprises a supporting base, a clamp assembly, a stamping-necking assembly and a press-down assembly. The stamping-necking assembly comprises two transverse stamping mechanisms symmetrically arranged on the two sides of the clamp assembly. The press-down assembly is fixedly arranged at the top end of the supporting base. The clamp assembly comprises two holding claws and a driving mechanism for driving the two holding claws to move towards each other. Each transverse stamping mechanism comprises a necking die for performing necking on the reducing flange. The press-down assembly comprises a circular punch for flat punching the portion, higher than the reducing flange, of the corrugated pipe. By manually and sequentially putting the corrugated pipe and the reducing flange into the assembling tool and then sequentially starting the stamping-necking assembly and the press-down assembly, the necking and locking process of the reducing flange and the flat punching process of the residual portion of the corrugated pipe are sequentially completed, time and labor are saved in the whole assembling process, and precision and reliability are higher compared with a hand making mode.

Description

technical field [0001] The invention relates to the field of bellows processing, in particular to a semi-automatic assembly tool for a gas bellows necking flange. Background technique [0002] Stainless steel bellows are widely used in the connection between gas appliances and gas pipelines. Stainless steel bellows are usually composed of three parts: the inner tube of the bellows, the rubber sleeve and the joint body. The inner pipe of the pipe is used for protection, and the joint body is arranged at the end of the inner pipe of the corrugated pipe. [0003] In the survival and manufacture of stainless steel bellows, the installation of the joint body is the most critical, and the installation form of the joint body directly affects the sealing performance of the stainless steel bellows in use. The joint body usually consists of three parts: a rotating nut, a fixed nut and a sealing ring. Between the nuts, when the gas pipeline or the gas appliance is connected, the seal...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is: the technical requirements for girth welding are high, and leakage will occur if the girth welding is not up to standard; and welding tools need to be carried during on-site installation, which increases the safety hazards of on-site installation and increases the installation cost

[0010] This process is generally made by workers on site with tools, and the reliability and firmness cannot be guaranteed. Therefore, it is necessary to design a semi-automatic tool that can quickly install the shrink flange on the end of the bellows.
