Description

Automatic pipe cutting device for automobile part production

Technical Field

The utility model relates to a linear cutting part processing device, in particular to an automatic pipe cutting device for automobile part production.

Background

A wire-cut electric discharge machine belongs to the field of electric machining, and is characterized by that when the phenomenon and reason of corrosion and damage of switch contact by spark discharge are studied by Soviet union, the instantaneous high temp. of electric spark can make local metal melt and oxidize and corrode, so that it develops and invents an electric spark machining method. The wire cutting machine was invented in the soviet union in 1960, and China is the first country for industrial production. The basic physical principle is that free positive ions and electrons accumulate in the field, quickly forming an ionized conductive channel. At this stage, a current is established between the plates. Resulting in numerous collisions between the particles, forming a plasma and rapidly rising to a high temperature of 8000 to 12000 c, momentarily melting some of the material on the surfaces of the two conductors, while a bubble is formed due to the evaporation of the electrodes and the dielectric liquid and its pressure rises regularly up to very high levels. The current is then interrupted and the temperature suddenly drops, causing the bubbles to implode, creating a motive force that throws the dissolved material out of the crater, and the corroded material recondenses into small spheres in the dielectric fluid and is drained away by the dielectric fluid. Then, the NC control monitoring and control is carried out by the servo mechanism, so that the discharge phenomenon is uniform and consistent, and the machined object is machined to become a product with the required size and shape precision. The wire-cut electric discharge machines can be classified into a high-speed reciprocating wire-cut electric discharge machine, a low-speed unidirectional wire-cut electric discharge machine and a vertical self-rotating wire-cut electric discharge machine according to the wire-cut speed. But also can be divided into a single-upright cross workbench type and a double-upright cross workbench type according to the workbench form.

The driving mechanism of the existing linear cutting machining equipment is limited in movement during machining, so that the machining speed is low, the existing linear cutting machining equipment is not provided with real-time tensioning equipment, deviation exists during wiring, the machining end face precision is low, and meanwhile, the electrode wire is unstable in fixation, and time and labor are wasted during replacement.

Therefore, the technical personnel in the field provide an automatic pipe cutting device for automobile part production to solve the problems in the background technology.
