Abstract

The invention provides a device for forming salient points on a pipe fitting. The device comprises a fixedly-arranged sleeve, an ejector rod and salient heads, guide holes are formed in the wall of the sleeve, the ejector rod comprises a conical surface section which is movably and penetratingly arranged in the sleeve along the axial direction of the sleeve, each salient head comprises a base and a supporting portion arranged on the base, the undersurface of each base and the conical surface section are in supporting contact, and each of the supporting portions is penetratingly arranged in the corresponding guide hole and has a first position protruding out of the guide hole and a second position for recovering into the guide hole. The device for forming the salient points on the pipe fitting solves the problem that forming the salient points on the pipe fitting is large in labor intensity, low in production efficiency and poor in uniformity in the prior art.

Description

technical field [0001] The invention relates to the technical field of pipe end forming processing, in particular to a device for embossing pipe fittings. Background technique [0002] In order to ensure the assembly length of welding, according to the design specifications of air-conditioning pipeline parts, it is required that when the pipe end needs to be flared and the external pipeline is required, positioning bumps must be made to control the matching length and matching gap between the two pipes. [0003] The consistency of positioning bumps and the effect of bump forming will directly affect the welding quality. In the existing technology, the bump forming process is completed by manual direct beating. Not only is the labor intensity high, the production efficiency is low, and its consistency cannot be guaranteed. . Contents of the invention [0004] The present invention aims to provide a device for embossing pipe fittings to solve the problems of high labor inte...
