Ultrasonic pipe end machining device

Abstract

An ultrasonic pipe end machining device is characterized by comprising a die clamping mechanism, a pipe end positioning mechanism, a transverse ultrasonic flaring mechanism, a top plate, a bottom plate, a front plate, a left plate and a right plate. The die clamping mechanism is arranged between the top plate and the bottom plate, and the pipe end positioning mechanism is installed on the front plate and fixedly connected with the front plate; the transverse ultrasonic flaring mechanism is installed on the left plate; the top plate is arranged between the left plate and the right plate and islocated at the upper ends of the left and right plates; the bottom plate is arranged between the left and right plates and located on the left plate; the front plate is arranged between the top plateand the bottom plate; the left plate is arranged at the left end of the top plate and the left end of the bottom plate and connected with the top plate and the bottom plate; the right plate is arranged between the top plate and the bottom plate and connected with the right ends of the top plate and the right end of the bottom plate. The device has the advantages that the efficiency is high and a die is durable.

Description

technical field [0001] The invention belongs to the field of metal tube processing, and in particular relates to a processing device for processing the nozzles of copper tubes and aluminum tubes by shrinking, expanding or ring-shaped convex-concave processing. Background technique [0002] In existing industrial or civil applications, metal pipes, especially copper pipes and aluminum pipes, need to be connected with other components such as pipe joints or pipe sockets during the application process. In order to achieve better sealing or firm connection, often It is necessary to process the nozzle end of the metal pipe, expand it into a bell mouth or other shapes, or shrink it; the existing pipe end processing methods often use single-station and multi-station pipe end processing devices, of which the single-station The station pipe end processing device can process copper and aluminum pipes at one time, but it has fast tool wear, high scrap rate, and is prone to defects such...

[0002] In existing industrial or civil applications, metal pipes, especially copper pipes and aluminum pipes, need to be connected with other components such as pipe joints or pipe sockets during the application process. In order to achieve better sealing or firm connection, often It is necessary to process the nozzle end of the metal pipe, expand it into a bell mouth or other shapes, or shrink it; the existing pipe end processing methods often use single-station and multi-station pipe end processing devices, of which the single-station The station pipe end processing device can process copper and aluminum pipes at one time, but it has fast tool wear, high scrap rate, and is prone to defects such as eccentricity, cracking and drumming; the existing multi-station pipe end processing machines mainly use The multi-station punch performs multiple processing and forming on the pipe end, which effectively solves the problem of high scrap rate. However, because this type of device requires multiple punching and expansion of a single pipe end before it can be formed, there are low processing efficiency and serious mold wear. question
