Embodiment Construction

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] As can be seen from the accompanying drawings, the present invention relates to a method for making a microporous metal wire drawing die, using tungsten carbide (WC) as the main material, adding appropriate amounts of titanium carbide (TaC) and cobalt (Co), tungsten carbide (WC) and The weight percentage of titanium carbide (TaC) and cobalt (Co) is 93-95%: 1.5-1.8%: 3.5-4.5%; after mixing the above-mentioned raw materials according to the proportion, after wet grinding, the overall grinding particle size of the mixture is less than 2 -3μm powder, then add spray drying molding agent for spray drying, and then send it into a pressing mold for compression molding to make a semi-finished product. After passing the inspection, remove the molding agent, and finally send it into a sintering furnace for sintering and molding to produce a microporous metal ...

Abstract

The invention discloses a manufacture method for a micropore wiredrawing die, which is characterized in that tungsten carbide (WC) is taken as a main material, an appropriate amount of titanium carbide (TaC) and cobalt (Co) are added, the weight percentage of tungsten carbide (WC), titanium carbide (TaC) and cobalt (Co) is (93-95 percent) : (1.5-1.8 percent) : (3.5-4.5 percent); and after mixing up the raw materials according to a proportion, wet grinding is carried out to enable the overall particle size of the ground mixed materials to be smaller than 2-3mu.m, then a spray drying formation agent is added to carry out spraying and drying, the materials are delivered into a compressive formation mould to be compressed and formed, a semi-finished product is manufactured, the formation agent is removed after the semi-finished product is inspected to be qualified, and finally the semi-finished product is sent to a sintering furnace to be sintered and formed, and the finish product of the micropore metal wiredrawing die is manufactured.

Description

technical field [0001] The invention relates to a component of a technical calendering machine and a manufacturing method for making a mold, in particular to a microporous wire drawing die and a manufacturing method for making the mold. Mainly used to make microporous metal wire drawing dies. Background technique [0002] Metal wires are used in many places in modern industry, and the required metal wires are getting thinner and thinner, making it more and more difficult to make metal wires. The current production of metal wire is generally made through a wire drawing die and metal drawing; the wire drawing die is a very important consumable die in the drawing production process of metal products enterprises. The scope of application of wire drawing dies is very wide, mainly used for drawing rods, wires, wires, pipes and other linear difficult-to-machine objects, suitable for drawing steel, copper, tungsten, molybdenum and other metals and alloy materials. Since the cost o...
