Desktop type pipe end machining machine

Abstract

The invention discloses a desktop type pipe end machining machine. The desktop type pipe end machining machine comprises a rotating unit, a machining unit, a feeding unit and a clamping unit. The clamping unit is used for clamping and fixing a to-be-machined guide pipe, the rotating unit is used for driving the machining unit to rotate, and the feeding unit is used for driving the machining unit to move to the end of the guide pipe clamped and fixed by the clamping unit. The rotating unit comprises a rotating motor, a mandrel, a liner and a dial. The mandrel is connected to the power output end of the rotating motor a mandrel eccentric hole is formed in the end of the mandrel, the liner is mounted in the mandrel eccentric hole, and a liner eccentric hole is formed in the end of the liner.By the adoption of the technical scheme, the desktop type pipe end machining machine can trim the tail end of the guide pipe, beading or flaring or chamfering or simple burring or side leveling can beselected, one machine can complete all functions, and only dies are replaced when one function is converted into another function.

Description

technical field [0001] The invention relates to a desktop-type pipe end processing machine, which belongs to the technical field of pipe processing equipment. Background technique [0002] The traditional pipe spinning and flaring machine can only work at a single station, and only has the flaring function. The flaring head adopts a concentric structure of 3 to 5 needle rollers. Thin, the thinning rate of the nozzle is as high as 40%, the root of the bell mouth is easy to break due to thinning, and the size of the head of the bell mouth increases due to thinning, it is difficult to accurately control the size of the bell mouth, and the metal conduit with high tensile strength and large wall thickness is processed , the needle roller is easily broken, and the replacement and adjustment of the needle roller is extremely inconvenient and time-consuming. [0003] The traditional tube chamfering machine can only work in a single station, and only has the chamfering function. The...

Problems solved by technology

This brings two disadvantages: one is that the clamping scar is obvious, which is not suitable for thin-walled tube processing; the other is that the clamping straight section is long, which is not suitable for the end flare of the small straight section forming catheter.

[0006] In addition to the same structure and function as the traditional CNC multi-station tube end forming machine, the CNC pipe end blunting machine developed by some manufacturers has added a rotating work station, which can perform circular processing functions such as chamfering, flat edge, and turning. , so as to realize the functions of chamfering, flaring, and blunt wave, but it brings two disadvantages: one is that the design of the chamfering clamping mold is longer, which is not suitable for the chamfering of small straight line forming catheters; the other is that the blunt wave adopts punching / Blunt pressure method, blunt wave shape is difficult to control, not suitable for high-demand fields
