Special machining device and method for double-end special-shaped hole piece

Abstract

The invention discloses a special machining device and method for a double-end special-shaped hole piece, and belongs to the technical field of machining. The special machining device for the double-end special-shaped hole piece includes a base, the top of the base is connected with a fixing frame, and the outer wall of the fixing frame is connected with a motor; the output end of the motor is connected with a rotating shaft, the end, away from the motor, of the rotating shaft penetrates through the fixing frame and is connected with a main bevel gear, and the auxiliary bevel gears are connected to the two sides of the main bevel gear in an engaged manner; the outer walls of the two auxiliary bevel gears are fixedly connected with the lead screws, the outer walls of the lead screws are inthreaded connection with the sleeves, and the outer walls of the sleeves are fixedly connected with the moving plates; the outer walls of the two moving plates are connected with a first punch and a second punch correspondingly, the top of the base is connected with a machined part, and the machined part is arranged between the first punch and the second punch. According to the present invention,the two ends of a workpiece are synchronously extruded, the machining speed of the workpiece is increased, the machining efficiency is improved, and the situation that the workpiece deforms or cracksis avoided in a heat treatment machining manner.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a special processing device and method for double-headed special-shaped hole parts. Background technique [0002] EDM is a kind of special processing technology. It is widely used in mold manufacturing and mechanical processing industries. EDM can be used to process superhard materials and workpieces with complex shapes that are difficult to process by traditional cutting methods. It is usually used to process conductive materials. Machining complex cavities or contours on difficult-to-machine materials such as titanium alloys, tool steels, carbon steels, and hard alloys is a method that uses the electric erosion effect generated by the pulse discharge between the two poles immersed in the working fluid to etch away the conductive material. Special processing methods for materials. [0003] However, because the electrical discharge machining process soaks the workp...

[0003] However, because the electrical discharge machining process soaks the workpiece in the working fluid, it can only process one end of the workpiece at a time, and cannot process both ends of the workpiece at the same time, resulting in slow speed and low processing efficiency of the electrical discharge machining process, and because the two ends are not At the same time, it is difficult to ensure that the special-shaped holes at both ends are on the same axis, and the punching process is used to punch the workpiece. Although the punching efficiency is relatively fast, the punch will squeeze the workpiece during the punching process. The internal stress of the workpiece increases, and the workpiece is deformed or cracked
