Abstract

The utility model discloses a compound hammer head, comprising a hammer head body which is composed of a hammer handle and a wearing layer arranged at front end of the hammer handle, which are made of casting single bodies with two different metal materials, and the hammer head body is an integrating structure by thermal compounding casting. By adopting the double metallic thermal compounding casting hammer and on the basis of keeping the original toughness of the hammer head, the wearing resistance of the hammer head is increased, the cracking resistance of the hammer handle is reliable, the production cost is greatly reduced, the service life of the hammer head is prolonged and the mechanical maintaining rate is low.

Description

A kind of composite hammer head

Technical field

The utility model relates to a kind of composite hammer head.

Background technology

The application of tup in various disintegrating machines is very extensive, is the main wearing piece of disintegrating machine, and the cost of tup and its wearability are directly connected to the production cost that disintegrating machine uses producer.The tup of existing production substantially all adopts medium carbon alloy steel, potassium steel or cast steel with high chromium, though medium carbon alloy steel, potassium steel toughness are better, hardness is low, and is anti-wear poor, and the preparation method of tup is mostly once cast for single kind metal liquid and is formed, not only wear no resistance, hammer handle cracking resistance poor reliability is produced the cost height of this kind tup, flight-line maintenance rate height, although people are by adjusting alloying component and changing Technology for Heating Processing, the result increases cost, and effect is not obvious.

The utility model content

Technical problem to be solved in the utility model is exactly that shortcoming at existing tup provides that a kind of wearability is good, the reliable composite hammer head of crack resistance.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of composite hammer head, comprise body, and it is characterized in that: described body is structure as a whole by the hot successively composite casting of several casting monomers.

Further, described body is made up of hammer handle and two of the wearing layers casting monomer that is located at the hammer handle front end.

Described wearing layer and hammer handle are formed by the different metal material casting.

As preferably, it is the raw material casting that described hammer handle adopts the ZG35 steel, reduces production costs; It is the raw material casting that wearing layer adopts 2 wear-resistant white cast KMTBCr20MoNi, and it is anti-wear to increase tup.

The utlity model has following advantage: adopt the hot composite hammer head of bimetallic, keeping on the original toughness of the tup basis, the wearability of tup increases, and the hammer handle crack resistance is reliable, and production cost reduces greatly, tup lengthening in service life, and the flight-line maintenance rate is low.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the utility model composite hammer head;

The specific embodiment

The structural representation of the utility model composite hammer head as shown in Figure 1, this composite hammer head is an one by wearing layer 1 and hammer handle 2 hot composite castings, wearing layer 1 and hammer handle 2 preferential employing 2 wear-resistant white cast KMTBCr20MoNi and ZG35 steel are raw material, and production cost is low, increases anti-wear.

1-3 times of the wearing part anti-wear performance raising of the utility model composite hammer head, material cost are fallen about one times, adopt the hot composite hammer head of bimetallic, keeping on the original toughness of the tup basis, the wearability of tup increases, the hammer handle crack resistance is reliable, and production cost reduces tup lengthening in service life greatly, the flight-line maintenance rate is low, and hammer handle assembling partly reliability improves greatly.
