Abstract

The utility model relates to a pick, it is used for milling the gear -shaping, digs tooth, tunnelling tooth and coal soon mines with technical field such as picks, and the name is a compound pick in electrodeposited diamond layer, brazed pick head on following pick handle and pick handle, the pick head be carbide or diamond glomerocryst piece, characterized by: the diamond layer of electroplating is in addition located to pick handle on every side below the pick head, also has the wear resistant tungsten carbide alloy -layer of one deck electroplating outside the pick handle and between the diamond layer, the pick handle be iron. Such compound pick in electrodeposited diamond layer has that the pick head is difficult for droing, long service life's advantage, can satisfy the requirement of some productions.

Description

A kind of electroplated diamond layer composite cutter bit

Technical field

This utility model relates to pick, and it digs the technology such as tooth, tunneling gear and coal mining pick for milling-planing teeth, rotation Field.

Background technology

At present, the application of pick is increasingly wider, digs tooth, development machine including milling machine milling-planing teeth, Spiral digging machine rotation With tunneling gear and coal mining pick etc..

Pick includes the cutting pick head of soldering on following cutting pick handle and cutting pick handle, in prior art, does not has around cutting pick head Matcoveredn, the cutting pick handle of such cutting pick head lower end is easy for abrasion, cutting pick head can be caused to come off after cutting pick handle abrasion, and pick loses Effect, causes service life short, changes frequently, the most seriously reduces work efficiency, and cause cost to be greatly increased.

Summary of the invention

The purpose of this utility model is aiming at disadvantages mentioned above, it is provided that a kind of cutting pick head difficult drop-off, length in service life Electroplated diamond layer composite cutter bit.

The technical solution of the utility model is achieved in that a kind of electroplated diamond layer composite cutter bit, including following The cutting pick head of soldering on cutting pick handle and cutting pick handle, described cutting pick head is hard alloy or dimond synneusis sheet, it is characterized in that: The diamond layer of plating is also had at the cutting pick handle of the surrounding below cutting pick head.

Say outside cutting pick handle and between diamond layer, also have the wear-resisting diamondite of one layer of plating further Layer.

Preferably, described cutting pick handle is irony.

Preferably, the described diamond layer number of plies is 1～10 layer.

The beneficial effects of the utility model are: such electroplated diamond layer composite cutter bit have cutting pick head difficult drop-off, Service life length advantage, can meet some produce requirements.

Accompanying drawing explanation

Fig. 1 is cross-sectional view of the present utility model.

1. cutting pick handle 2. cutting pick head 3. diamond layer in figure.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further illustrated.

As it is shown in figure 1, a kind of electroplated diamond layer composite cutter bit, including soldering on following cutting pick handle 1 and cutting pick handle Cutting pick head 2, described cutting pick head is hard alloy or dimond synneusis sheet, it is characterized in that: cutting around below cutting pick head The diamond layer 3 of plating is also had at tooth handle.

Complete at a temperature of whole electroplating process is relatively low at one, therefore avoid and pick is heated again, Hardness and the intensity of cutting pick handle after heat treatment can be kept.

This utility model, owing to also having the diamond layer 3 of plating at the cutting pick handle around below cutting pick head, adds The wearability at this position, it is possible to achieve the purpose of this utility model.

So increase its hardness, reduce its manufacturing cost.

Preferably, described cutting pick handle is irony.So coating and cutting pick handle connects more firm.

Preferably, the described diamond layer number of plies is 1～10 layer.

Claims

1. an electroplated diamond layer composite cutter bit, including the cutting pick head of soldering on following cutting pick handle and cutting pick handle, described Cutting pick head is hard alloy or dimond synneusis sheet, it is characterized in that: also have plating at the cutting pick handle around below cutting pick head Diamond layer.

Electroplated diamond layer composite cutter bit the most according to claim 1, is characterized in that: outside cutting pick handle and diamond layer Between also have one layer plating wear-resisting diamondite layer.

Electroplated diamond layer composite cutter bit the most according to claim 1 and 2, is characterized in that: described cutting pick handle is irony 's.

Electroplated diamond layer composite cutter bit the most according to claim 3, is characterized in that: the described diamond layer number of plies is 1 ～10 layers.
