Embodiment Construction

[0016] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] as attached figure 1 and 2 Shown, the present invention discloses a kind of processing method of cemented carbide extrusion die, comprises the following steps:

[0018] According to the shape of the tungsten carbide extrusion die, the corresponding matching shape of the electroplated diamond grinding wheel is designed. Grinding is carried out in the alloy extrusion die, and the clamping size of the electroplated diamond grinding wheel is determined according to the chuck size of the machining center or milling machine.

[0019] The electroplated diamond grinding wheel is set on the milling machine and the machining center, and the semi-finished product of the cemented carbide extrusion die is ...

Abstract

The invention discloses a processing method for a hard alloy extrusion mould. The processing method comprises the following steps: according to the shape of the hard alloy extrusion mould, designing electroplated diamond grinding wheels with corresponding matched shapes; arranging the electroplated diamond grinding wheels on a milling machine and a processing centre, and driving the electroplateddiamond grinding wheels to grind a semi-finished product of the hard alloy extrusion mould to remove a remaining material of the semi-finished product of the hard alloy extrusion mould; and after theelectroplated diamond grinding wheels finish grinding, trimming the hard alloy extrusion mould by utilizing an electrical discharge machine to complete a preset shape. According to the processing method for the hard alloy extrusion mould, the remaining material of the hard alloy extrusion mould is ground by utilizing the electroplated diamond grinding wheels, so that the remaining material removaltime is shortened; the processing efficiency is improved; and the production cost is reduced.

Description

technical field [0001] The invention belongs to the processing field of extrusion dies, in particular to a method for processing and removing leftover materials of cemented carbide extrusion dies. Background technique [0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , It still has a high hardness at 1000 °C. Cemented carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting Difficult-to-machine materials such a...
