Abstract

The invention relates to the technical field of machine tools for machining workpieces, and discloses a moving core head production process. The moving core head production process comprises the following steps that firstly, rectangular hard alloy is selected, and the surface of the hard alloy is smooth and flat; secondly, the hard alloy is transferred to a milling machine to be fixed; and thirdly, the hard alloy is machined through a milling cutter on the milling machine, and a moving core head is obtained. In the second step, fixing equipment for fixing the hard alloy is installed on the milling machine and comprises a workbench and a movable block, a fixed block and an air cylinder are installed on the workbench, and an output shaft of the air cylinder is fixedly connected with the movable block; and a vertical groove is formed in the side wall of the fixing block, and the fixing equipment further comprises a limiting mechanism vertically moving along with the hard alloy to limit the lower corner of the hard alloy. According to the scheme, the problem that the clamping effect of a traditional clamping mechanism on the hard alloy is poor due to the fact that the hard alloy is subjected to acting force in multiple directions when the hard alloy is machined into the moving core head is mainly solved.

Description

technical field [0001] The invention relates to the technical field of machine tools for processing workpieces. Background technique [0002] Swimming core head, alias: inner core head, is mainly used for drawing copper pipes, and is used in conjunction with pipe drawing dies (also known as outer dies, drawing dies). The swimming core head is not fixed in the copper pipe. The friction force of the copper tube and the reaction force when the copper tube is deformed reach a balance state, so it is called a floating core head, and there is a fixed core head opposite to it. [0003] At present, the moving core is generally made of cemented carbide, and the rectangular cemented carbide is usually processed; during the processing, the positioning of the cemented carbide is involved. The traditional positioning method is mainly realized by clamping. The traditional clamping mechanism includes a workbench and a power part. A fixed block is fixedly connected to the workbench. The po...
