Copper pipe necking machine

Abstract

The invention discloses a copper pipe necking machine. The copper pipe necking machine structurally comprises an equipment body, a necking device, a stroking and pressing correction device, a feedingport and a controller. The copper pipe necking machine has the beneficial effects that through mutual cooperation of a limiting stroking mechanism and a straightening structure, after a copper pipe isplaced into the feeding port, limiting type straightening rotation fit is conducted on the copper pipe, and therefore the situation that under the compression effect of equipment, the copper pipe istransversely deviated during placement, consequently the precision of a necked copper pipe opening is not accurate, and the copper pipe can not be used accurately in the later use process is avoided;and according to the copper pipe necking machine, an arranged face protection piece is matched with an air bag to conduct extrusion type stroking along with cooperation of an inclination restraining assembly in a conical cavity, so that the blowing effect of airflow on the surface of the copper pipe is achieved, the effect of primary cooling cooperation of the surface of the copper pipe is achieved, and through cooperation of stroking strips, residual scraps on the surface of the copper pipe are wiped in a matched mode.

Description

technical field [0001] The invention relates to the field of necking machines, more precisely, it relates to a copper pipe necking machine. Background technique [0002] With the improvement of copper tube manufacturing technology, the use of copper tubes has been widely used in various fields, and because some fields have special requirements for the use of copper tubes, it is necessary to use a shrinking machine to shrink them. mouth processing. [0003] However, when using the necking machine to shrink the copper pipe, because the traditional necking equipment is usually operated manually, the copper pipe is sent to the inside of the necking machine to achieve the effect of necking, but due to the When the tube is fed into the necking machine, it is prone to lateral deviation of the copper tube, which in turn leads to inaccurate accuracy of the copper tube after shrinking. At the same time, after the necking machine has been used many times, its The temperature at the f...

Problems solved by technology

[0004] Aiming at the deficiencies existing in the prior art, the object of the present invention is to provide a copper tube necking machine to solve the problem in the prior art that when using the necking machine to shrink the copper tube, the traditional necking equipment usually It is to use manual operation to send the copper tube into the necking machine to achieve the effect of shrinking. However, when the copper tube is fed into the necking machine, it is easy to cause the horizontal offset of the copper tube to be fed, which in turn leads to The accuracy of the copper tube is inaccurate after shrinking. At the same time, after the shrinking machine is used for many times, the temperature at the feeding port increases significantly, so that the surface temperature of the next batch of copper tubes after being fed will be lower. It is higher than the normal copper pipe necking condition, and the surface will be mixed with debris due to high temperature, so that it will shrink together.
