Problems solved by technology

This processing technology is transplanted from the processing technology of aluminum and steel profiles. It is not completely suitable for copper tubes with certain flexibility. Therefore, it is difficult to obtain thin-walled and uniform and smooth capillary tubes for the reduced-diameter tubes rolled. ; Moreover, when manufacturing multi-stage reducers, it is difficult to accurately locate the lengths of each stage

Embodiment Construction

[0037] The device of the present invention mainly includes a swaging machine 7, and a traction stretching device arranged on a frame. Among them, the rotary forging machine 7 is selected to include a motor 7-1, a transmission belt 7-2, a turntable 7-3, a fixed ring seat 7-4, a cylinder 7-5, a power transmission vibration block 7-6, and a set of Forging machinery with dies 8 and 8`. Among them, the motor drives the turntable 7-3 to rotate at high speed through the transmission belt, and many cylinders 7-5 are fixed on the fixed ring seat 7-4. A group of forging dies 8, 8` are placed in the middle of the groove on the turntable, with A power transmission vibration block 7-6, because the groove of the force transmission vibration block is slightly wider than the key 7-7, there is a gap between the two, the force transmission vibration block is limited in the gap, and can do linear motion back and forth; the turntable rotates At this time, the circular arc surfaces on the outer s...

Abstract

The invention relates variable aperture tube making method and device, including tube end rotary forging and draw stretching. It first forges one end of the tube on the rotary forger into a smaller-aperture technical tube, which makes the stretching mould through to be clamped by the clamping module; using a hydraulic control system to drive clamping base and clamping module; inserting core rod with mould head in the copper tube to stretch by the stretching mould. It includes rotary forger and draw-stretching device. The clamping module, the stretching mould and the core rod makes up a stretching process line. The position of the core rod is adjustable and the stretching effect is good. The hydraulic control system is installed with travel switch to control stretching travel. It is applied to the control of thin-wall small-aperture copper tube and widely applied to cryogen pipeline in refrigerating industry.

Description

technical field [0001] The invention relates to a method and a device for manufacturing a diameter-reducing tube, in particular to a method and a device for stretching and manufacturing a diameter-reducing pipe used as a refrigerant pipeline in the refrigeration industry. Background technique [0002] In the refrigeration industry such as air conditioners and refrigerators, a large number of copper tubes are used as refrigerant circulation pipes. Due to technological needs, such as throttling and pressure reduction and flow control, etc., it is often necessary to connect the capillary tube with the transition tube, or connect two sections of copper tubes with different diameters to form a tapered tube or a trapezoidal tube. Reducer, or multi-stage trapezoidal tube. The existing reducing pipes used in the refrigeration industry are basically manufactured by welding. As we all know, copper metal welding, especially seam welding of thin-walled and small-diameter copper pipes,...
