Sliding block type pipe expanding die

Abstract

The invnetion discloses a sliding block type pipe expanding die. The sliding block type pipe expanding die is characterized in that a tool box is fixedly installed in the middle of the front face of abase, an abutment is arranged at the bottom end of the base, and a main body is arranged at the top end of the base; and a first sliding groove and a second sliding groove are embedded in the top endof the body, an extrusion device, a lower die and a distance adjusting device are sequentially and fixedly installed from one side to the other side of the surface of the top end of the body, an extrusion machine base and an adjusting hand wheel are arranged at the bottom of the extrusion device, and a double-stroke oil cylinder, a telescopic extrusion rod and a pipe expanding head are arranged at the top of the extrusion device. According to the sliding block type pipe expanding die, the internet of things and a calibration block intelligent control device are arranged to rapidly and accurately fix a pipe to be machined, the machining efficiency is improved, and the labor cost is reduced; a pipe taking device auxiliary device is arranged to automatically take down a machined pipe, a nextpipe is conveniently and directly placed, the pipe machining efficiency is improved, and the manual labor intensity is reduced; and a distance adjusting device and multiple sets of sliding groove andsliding block auxiliary devices are arranged to adjust the distance, and therefore various pipes can be conveniently used for machining.

Description

technical field [0001] The invention relates to the technical field of pipe expanding dies, in particular to a slider type pipe expanding die. Background technique [0002] Tube expansion is to process thin tubes into thicker tubes with different processes. It is a cold plastic forming process. It usually uses a tapered mold to pass through the inner hole of the metal pipe under pressure, so that the inner diameter of the metal pipe and A deformation method of outer diameter expansion. The expansion deformation of metal pipe fittings can improve the cross-sectional shape of the pipe and improve the dimensional accuracy of the pipe. [0003] In the prior art, there are certain shortcomings when expanding the nozzle of the pipe fittings. First, when the existing pipes are placed on the device and fixed, most of them are fixed by manual mechanization. The operation process is cumbersome and requires multiple It is very cumbersome for the operators to use multiple equipments. S...

Problems solved by technology

[0003] In the prior art, there are certain shortcomings when expanding the nozzle of the pipe fittings. First, when the existing pipes are placed on the device and fixed, most of them are fixed by manual mechanization. The operation process is cumbersome and requires multiple It is very cumbersome for the operators to use multiple equipments. Second: Since each operation process requires manual intervention, the efficiency is not high. When removing the pipe, it needs to be manually removed after the pipe is processed, and the pipe is locked in the mold due to the pressure during processing. , it takes time and effort to take it out, and there is a big safety hazard; third: in addition, if it is to be processed in large quantities, if the lengths of pipe fittings are different in each batch of processing, it is more troublesome to adjust the device, so it cannot meet the actual requirements
