Abstract
The method for manufacturing internal-threaded pipe, especially the refrigerating pipe in heat exchanger, features that the pipe blank extruded and straightened is passed through by core rod with surficial skewed slots at its head and is drawn with die and the core head. The core rod supporter has stand, slide sleeve including inner and outer ones, and bearing to ensure the core rod rotational.
Description
The present invention relates to the manufacture method and the device of copper aluminium matter riffled tube.
The manufacture method that is used for the copper aluminium matter riffled tube of refrigerator and air conditioner evaporator at present is extruding-torsional technique, promptly at first squeeze out the linear striped at inside pipe wall by the method for pushing, reverse reversing on the equipment of special use then, the linear striped becomes spiral fringe in the pipe thereby make.As by Japan described on October 20th, the 1987 disclosed clear 62-240109.This kind technology is complicated, and the equipment frock expense is higher, is difficult for guaranteeing the circularity of pipe, and the internal thread swing angle is inhomogeneous, influences the quality of product, also has report to adopt the method for spinning to produce riffled tube.
The objective of the invention is in order to overcome the deficiency of above-mentioned technology, propose that a kind of technology is simple, production cost is low, the manufacturing method and apparatus of the riffled tube of good product quality.
The manufacture method of riffled tube is characterized in that: a. at first extrudes the shell alignment to ingot blank with extruder; B. the shell after the alignment being through the surface has on the core bar of skewed slot core print; C. carry out drawing by drawing mould and core print; D. cut away tube head scale as required.
Be used to make the core bar bracing or strutting arrangement of riffled tube, comprise fixed head, supporting base, it is characterized in that: be provided with in supporting base by the sliding sleeve that slips with supporting base, interior cover is connected the rotating supporting arrangement of core bar that bearing that overcoat is connected with sliding sleeve is formed with the core bar afterbody.
The present invention compared with the prior art process for making and process equipment is simple, easy to operate, and major parameters such as the circularity of riffled tube and the angle of rifling are guaranteed, and have improved product quality, have reduced the production cost.
Accompanying drawing is a core bar supporting arrangement schematic diagram.
The present invention is further described as follows below in conjunction with accompanying drawing.
The manufacture method of riffled tube is characterized in that the shell alignment of at first copper, aluminium ingot base being extruded with extruder; Then the shell after the alignment being through the surface has on the core bar of skewed slot core print; Carry out drawing by drawing mould and core print again; Cut away tube head at last and need scale by the user.
Be used to make the core bar supporting arrangement of riffled tube, comprise fixed head 3, supporting base 1, it is characterized in that: be provided with in supporting base by the sliding sleeve 4 that slips with supporting base, interior cover is connected the rotating supporting arrangement of core bar that bearing 5 that overcoat is connected with sliding sleeve is formed with core bar 2 afterbodys.When shell process drawing mould and core print, the tangential force of using the oblique mould generation of shell inwall and core print is rotated core bar under the supporting of core bar supporting arrangement, and drawing goes out riffled tube.
