Embodiment approach

[0025] Such as Figure 1 to Figure 3 As shown, pass the copper pipe that needs to be stretched in sections through the fixed chuck 6, adjust the fixed chuck 6, tighten the copper pipe, open the PLC controller 11 and the high-pressure oil pump 5, so that the PLC controller 11 controls the high-pressure oil pump 5, Adjust the contraction of the cylinder 4 through the high-pressure oil pump 5, thereby driving the stretching of the steel pipe, and sensing the stretching length of the copper pipe through the displacement sensor 10. The stretching length needs to be input into the PLC controller 11 in advance. When the section of the copper pipe stretches to the required After the length, loosen the fixed chuck 6, adjust the position of the copper tube, clamp the end of the other section of the copper tube that needs to be stretched by the fixed chuck 6, tighten the fixed chuck 6, and repeat the previous step; when the entire copper tube After the stretching is finished, the copper ...

Abstract

The invention provides a copper pipe section drawing device for solving the problems, such as leakage points, deformation, breakage, rough appearance and thick pipe wall, which easily occur in a traditional copper pipe section drawing device. The device comprises a bracket and a drawing die on the bracket, wherein the drawing die is connected with the bracket through a sliding rail on the bracket; the sliding rail is fixedly connected with the bracket; a cylinder is arranged on the other side of the sliding rail; a barrel of the cylinder is fixedly connected with the bracket; a piston rod of the cylinder is fixedly connected with the drawing die; a high-pressure oil pump for providing power for the cylinder is connected to the cylinder and is fixed on the bracket; the drawing die comprises a fixed chuck and a fixed base which is fixedly connected with the fixed chuck; the drawing die is fixedly connected with the piston rod of the cylinder through the fixed base; a programmable logic controller (PLC) is arranged on the bracket.

Description

technical field [0001] The invention relates to a stretching device, in particular to a segmented copper tube stretching device, which belongs to the field of copper tube stretching. Background technique [0002] Existing transition pipes generally adopt the method of welding thick pipes with thin pipes. Due to the welding process, this method is prone to leaks and has great hidden dangers. Another method is to use a twisting machine to twist and reduce the diameter of one end. In this way, when the slider inside the twisting machine is rotated and hit, the pipe is subject to a large force locally, which is easy to deform and break, and the appearance is rough and the yield is not high. , and the pipe wall thickness increases after twisting, wasting resources. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a segmental stretching device for copper tubes, which solves the problems that traditional segmental str...
