Problems solved by technology

[0003] At present, the shunts circulating in the market are all processed by the surrounding extrusion method of the hydraulic press. The disadvantage is that there are several wrinkles on the surface and inside of the pipe body and the pipe wall is not thickened. It needs to be polished inside and outside to make it clean and beautiful. After polishing, the pipe body becomes Thin, only shallow machining of internal threads
Moreover, in order to ensure the thread's ability to withstand water pressure, the pipe body cannot be polished too much, and often the wrinkles cannot be completely polished, which will affect the appearance

Embodiment 1

[0021] A process for processing the end of a geothermal heating splitter, the processing steps of which include:

[0022] The first step is to place the tube body in an electric furnace at a temperature of 180°C for 10 minutes to stabilize the molecular structure inside the tube body;

[0023] In the second step, adopt with The two ends of the pipe body are subjected to eight consecutive up-and-down reciprocating movements of the punching machine and extrusion processing. The friction generates high temperature, and the pipe wall becomes soft due to the high temperature, so that the original internal molecular structure is transferred to the inside and the upper part to achieve the increase of the pipe wall. thick purpose;

[0024] In the third step, the ends of the two ends of the pipe body are processed into a circular shape, and the processed ends are connected with the original square pipe through an arc;

[0025] In the fourth step, threads are respectively process...

Abstract

The invention relates to the technical field of geothermal heating flow divider machining and particularly relates to an end machining technology for a geothermal heating flow divider, comprising the machining steps of: firstly, standing a pipe body in an electric heating furnace at the temperature of 180-250 DEG C for 10-20min, and stabilizing a molecular structure in the pipe body; secondly, enabling a punching machine to continuously act up and down in a reciprocated way for at least five times by adopting different special necking dies, extruding, rubbing to generate high temperatures, softening the pipe wall by high temperature to enable an internal original molecular structure to transfer towards the inner side and the upper part to achieve the aim of thickening the pipe wall; thirdly, machining the two ends of the pipe body to be round, and connecting the processed ends with an original square pipe through a circular arc; and fourthly, respectively machining screw threads inside the two ends of the pipe body. The flow divider manufactured by using the machining technology disclosed by the invention is round at two ends, is thickened in pipe wall as well as smooth and clean in appearance.

Description

technical field [0001] The invention relates to the technical field of geothermal heating diverter processing, in particular to an end processing technology of a geothermal heating diverter. Background technique [0002] The floor heating manifold and water collector (manifold) are water distribution and collection devices used to connect the supply and return water of various heating pipes in the water system. Water collector or water collector, commonly known as water separator or diverter. The diverter is an important part of the geothermal heating diversion device. [0003] At present, the shunts circulating in the market are all processed by the surrounding extrusion method of the hydraulic press. The disadvantage is that there are several wrinkles on the surface and inside of the pipe body and the pipe wall is not thickened. It needs to be polished inside and outside to make it clean and beautiful. After polishing, the pipe body becomes Thin, only shallow machining o...
