Annealing and drawing device for oxygen-free copper tube, with high diameter-to-thickness ratio, for mobile phone heat pipe

Abstract

The invention discloses an annealing and drawing device for an oxygen-free copper tube, with high diameter-to-thickness ratio, for a mobile phone heat pipe. The annealing and drawing device comprisesa box body; a drawing die is mounted in the box body; an annealing pipe is mounted between the drawing die and the box body; a heating wire is wound around the side wall of the annealing pipe; a fixing plate is arranged on one side of the drawing die; a supporting roller is rotationally connected onto the fixing plate; a tension adjusting mechanism is arranged on one side of the supporting roller;a mounting plate is arranged on the outer side of one end, close to the tension adjusting mechanism, of the box body; the mounting plate is mounted on the ground; a supporting frame is fixed to one side of the upper end of the mounting plate; a servo motor is fixed to the upper end of the supporting frame; a rotating shaft is fixed to the end part of an output shaft of the servo motor; a windingwheel is in keyed connection onto the rotating shaft; and a supporting mechanism is arranged at one end, far from the servo motor, of the rotating shaft. Through the adoption of the structure, the oxygen-free copper tube for the mobile phone heat pipe is uniform in annealing, and uniform in drawing traction, and the production quality of a rope is improved.

Description

technical field [0001] The invention belongs to the technical field of processing equipment for oxygen-free copper tubes for mobile phone heat pipes, in particular to an annealing and drawing equipment for oxygen-free copper tubes for mobile phone heat pipes with a high diameter-thickness ratio. Background technique [0002] At present, there are various sizes and specifications of oxygen-free copper tubes for mobile phone heat pipes on the market. There are two indicators for testing the performance of oxygen-free copper tubes for mobile phone heat pipes, which are the outer diameter and wall thickness. The outer diameter is large and the wall thickness is small. Products, the obvious performance is superior, that is to say, the diameter-thickness ratio of the heat pipe of the mobile phone is a substantive index to measure the heat dissipation performance of the heat pipe of the mobile phone. [0003] The production of oxygen-free copper tubes for mobile phone heat pipes ad...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an annealing and drawing equipment for oxygen-free copper tubes for mobile phone heat pipes with a high diameter-to-thickness ratio, so as to solve the problem of the existing oxygen-free copper tubes for mobile phone heat pipes in the above-mentioned background technology. Oxygen-free copper tubes are used to pass through the annealing furnace. Due to the large space of the annealing furnace and the uneven internal temperature, the annealing of the oxygen-free copper tubes for heat pipes is uneven, which affects the subsequent drawing process, and the energy consumption is large and the cost is high. Oxygen-free copper tubes are drawn through the drawing die by traction, but due to the small diameter and long length of the oxygen-free copper tubes for heat pipes, the oxygen-free copper tubes for heat pipes will loosen during the drawing process, resulting in uneven traction. In turn, the drawing quality of oxygen-free copper tubes for heat pipes is not uniform, and defects are prone to occur
