Embodiment Construction

[0033] use Figure 1-Figure 10 A powder metallurgy tool steel mixing equipment and its use method according to an embodiment of the present invention are described as follows.

[0034] Such as Figure 1-Figure 10 As shown, a kind of powder metallurgy tool steel mixing equipment and its use method described in the present invention comprises the following steps:

[0035] S1: Check the airtightness of the mixing equipment, connect the feeding end of the equipment with the external gas pipe, and after ensuring that the sealing effect of the connection is up to standard, detect and observe whether the pipeline exposed to the outside of the mixing equipment is blocked or leaks;

[0036] S2: After the air tightness test of the mixing equipment reaches the standard, start the equipment, and put the powdered raw materials required for metallurgy into the inside of the mixing equipment in sequence according to the actual production needs;

[0037]S3: During the operation of the mixin...

Abstract

The invention belongs to the field of powder metallurgy, and relates to powder metallurgy tool steel mixing equipment and a using method thereof. The mixing equipment comprises a machine body, an air inlet pipe is fixedly connected to the outer surface of the left side of the machine body, and a feeding pipe is arranged at the top of the air inlet pipe. According to the powder metallurgy tool steel mixing equipment and the using method thereof, an exhaust mechanism is adopted, when the equipment works, under the action of air pressure, a sealing plate moves downwards, the outer surface of a one-way valve is separated from a feeding pipe, materials enter the equipment from a through hole, a push-pull rod moves downwards, and the outer surface of a sealing plug slides along the inner surface of a rubber plate, air blown in by the air inlet pipe is exhausted out of the equipment, under the multi-stage sealing effect of the sealing plug and the rubber plate, the exhaust mechanism can guarantee the air tightness of the equipment while meeting the exhaust effect, metal dust in the air is blocked in the equipment through an exhaust pipe and a baffle ring, dust raising is prevented, the problems that dust raising and blocking are prone to occurring when traditional powder metallurgy is used are solved.

Description

technical field [0001] The invention belongs to the field of powder metallurgy, and in particular relates to a powder metallurgy tool steel mixing equipment and a using method thereof. Background technique [0002] Powder metallurgy high speed steel, referred to as powder metallurgy high speed steel, or PM high speed steel. A high-speed steel profile obtained by using powder metallurgy method (atomized powder is subjected to isostatic pressing treatment in a hot state) to obtain a dense billet, and then subjected to thermal deformation such as forging and rolling. Powder high-speed steel has uniform structure and fine grains, which eliminates the unavoidable segregation of cast high-speed steel, so it has higher toughness and wear resistance than cast high-speed steel with the same composition, and also has small heat treatment deformation, forging and rolling performance and wear resistance. Good cutting performance and other advantages. [0003] Since the raw material is...
