Abstract
The utility model relates to a conical bit of coal mining machine without cemented carbide, which is particularly used for various mines and coal mining and belongs to mining tool technical field. The utility model is mainly characterized in that a cutting pick rod and a cutting pick head are integrated into a whole, and the cutting pick head is coated with a wear-resistant coating. The thickness of the wear-resistant coating is 0.5-1mm. As the utility model is a novel product with novel metal surface modification technology and novel process of strengthening and toughening by compound heat treatment, the performances of the utility model of wear-resistance, impact resistance, high temperature resistance, corrosion resistance, high hardness and low consumption are better than that of traditional cemented carbide product and the service life is greatly improved; as the working end of the cutting pick head is inlayed with no cemented carbide and integrated manufacture is realized, seismic and anti-impact strength can be improved; as the cutting pick rod, the cutting pick head and the wear resistance coating have been quenched and tempered with strengthening and toughening by heat treatment, high strength of anti-bending, anti-breaking and anti-impact can be achieved.
Description
Technical field
The utility model relates to a kind of coal-winning machine pick-like bit that does not have carbide alloy, specifically is used for coal mining, various mine operation, engineering, constructing tunnel, belongs to the coal mining technical field of tools.
Background technology
In existing coal mining technology, the soldering carbide alloy is all inlayed on the top of the pick-like bit of coal-winning machine, and its basic hardness requires at HRC38-42.In coal mining activity, the coal-winning machine pick-like bit is to rely on the toughness of the anti-wear performance of carbide alloy and matrix modifier treatment and intensity work, and the industry of for many years mining is being kept the manufacture craft of this traditional ancient backwardness always and do not improved.In actual job uses, because the problem of material, hardness, intensity, aspect such as wear-resisting, it is short to cause the coal-winning machine pick-like bit to exist life cycle, changes many shortcomings such as frequent, that production efficiency is low, loss is big, cost is high, and intensity is low, anti-wear performance is poor, application life is short.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby not carbide inserts of a kind of coal-winning machine pick-like bit working end is provided, and it has wear-resistant, shock-resistant, high temperature resistant, corrosion resistant performance, and greatly improve application life.
Main solution of the present utility model is achieved in that
The utility model adopts pick bar and cutting pick head to fuse, and feature is to be laminated with abrasion resistant coating on cutting pick head.Abrasion resistant coating thickness is: 0.5～1mm.
Compared with the prior art the utility model has the following advantages:
The utility model is because the product that adopts metal surface modification new technology and Strengthening and Toughening Compound Heat Treatment new technology to make, it is wear-resistant, shock-resistant, high temperature resistant, corrosion-resistant, high rigidity, low consumed performance have all surpassed traditional hart metal product, and greatly improve application life; Because the carbide inserts not in the working end of cutting pick head has been realized integrated manufacturing, can improve antidetonation, impact resistance intensity; Because pick bar, cutting pick head, reach bending resistance, anti-disconnected, impact resistance high strength through the Strengthening and Toughening heat treatment quenching and tempering.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in the figure: carbon and low-alloy structural steel 35CrMo material forged and is integral during the utility model pick bar 1, cutting pick head 2 adopted.Steps such as forging warp, annealing, metalworking are laminated with metal carbides coating 3 then on cutting pick head 2, again through heat treatment, verify as finished product.
These abrasion resistant coating 3 thickness are: 0.5～1mm, abrasion resistant coating 3 adopts chromium, vanadium, niobium metal powders and nonmetal boron, the carbon compound material is composite forms.
The utility model hardness pick bar 1 reaches HRC:38～42, cutting pick head 2 hardness HRC＞60, abrasion resistant coating 3 hardness HV＞1800.
Claims (2)
1. coal-winning machine pick-like bit, pick bar (1) fuses with cutting pick head (2), it is characterized in that being laminated with on cutting pick head (2) abrasion resistant coating (3).
2. coal-winning machine pick-like bit according to claim 1 is characterized in that described abrasion resistant coating (3) thickness is: 0.5～1mm.
