Abstract
The utility model relates to a mushroom type pressed pick-type bit, comprising a bit body and a bit head and a bit handle, wherein the bit head and the bit handle are integrated into a whole body; andthe top part of the bit body is provided with a bit seat which is provided with an installing cavity along the axis thereof. The mushroom type pressed pick-type bit is characterized in that the bit head is mushroom type; the side wall of the bit handle is provided with an axial air groove; the bit head is assembled in the installing cavity by the bit handle; and the connection limiting part of the bit head and the bit seat is arranged into an arc shape. In the mushroom type pressed pick-type bit, the bit head and the bit seat are matched by the bit handle in an interference-fit manner; the connection limiting part of the bit head and the bit seat is arranged into an arc shape structure; and the mushroom type pressed pick-type bit is not burst, is not easy to fall, is made of high-strengthsteel, and has good wear resistance, thus greatly prolonging the service life compared with the common bit head, improving production safety and reducing production cost.
Description
Technical field
The utility model belongs to the exploitation of mineral resources technical field, relates to a kind of coal-winning machine easy-abrasion part, specifically is a kind of mushroom-shaped forced pick-shaped cutter.
Background technology
Coal winning machine cutting bit head of the prior art is a fritter carbide alloy, and it passes through high-frequency welding technology and denticle be combined into, but often owing to inevitable defective on this body structure and the processing technology, causes application life shorter.Reason is as follows: one, a fritter tip of 75 degree is Hardmetal materials, and its hardness is higher really, but the working environment complexity of coal winning machine cutting bit is often run into bigger stone of intensity such as gangue etc. in the coal seam, can explosion voluntarily.Higher because of welding temperature when two, making up, following denticle must need annealed processing, influences bulk strength, and is not wear-resisting.Therefore,, certainly will cause the denticle wearing and tearing to be accelerated, make hard alloy head rely on and come off because of not having through the continuous operation of long-time many order of classes or grades at school.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of intensity height, abrasion resistance good, can not split, be difficult for dropping, the mushroom-shaped forced pick-shaped cutter of long service life.
The purpose of this utility model realizes by following technical scheme: described mushroom-shaped forced pick-shaped cutter comprises the cutting pick head and the pick handle of pick body and one, described pick body top is provided with pick box, pick box offers the installation cavity along its axis, it is characterized in that: described cutting pick head is mushroom-shaped, offer axial air drain on the described pick handle sidewall, cutting pick head is assemblied in the described installation cavity by the pick handle, and cutting pick head is connected limiting section with pick box and is made as circular arc.
As further improvement of the utility model, described pick handle and pick box adopt the embedded mode interference fit of colding pressing.
As further improvement of the utility model, described cutting pick head and pick handle adopt the manufacturing of 4Cr5MoSiV1 shaped steel.
As further improvement of the utility model, the height of described cutting pick head is 1/3～1/2 of cutting pick head and a pick box height sum.
The utility model compared with prior art, cutting pick head is by pick handle and pick box interference fit, cutting pick head is connected limiting section with pick box and is made as arc-shaped structure, can explosion, be difficult for dropping, adopt the high strength steel manufacturing, abrasion resistance is good, greatly prolong, improved production security than existing common cutting pick head application life, reduced cost of production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, described mushroom-shaped embedded pick-shaped cutter comprises the cutting pick head 1 and pick handle 2 of pick body 4 and one, described pick body 1 top is provided with pick box 3, pick box 3 offers along its axis cavity 5 is installed, described cutting pick head 1 is mushroom-shaped, offer axial air drain 6 on described pick handle 2 sidewalls, be used for exhaust when pick handle 2 is pressed into installation cavity 5 on the pick box 3; Cutting pick head 1 is assemblied in the described installation cavity 5 by pick handle 2, and pick handle 2 adopts the embedded mode interference fit of colding pressing with pick box 3, and the height of cutting pick head 1 is cutting pick head 1 and 1/3～1/2 of pick box 3 height sums; Cutting pick head 1 is connected limiting section with pick box 3 and is made as circular arc.
Described cutting pick head 1 adopts high-strength special type steel such as 4Cr5MoSiV1 shaped steel to make with pick handle 2, and handles by nano particle infiltration technology and Technology for Heating Processing, has the Wear-resistant, high-temperature resistant characteristics; Adopt the mode of interference fit to be pressed in the installation cavity 5 on the pick box 3 then, cutting pick head 1 is connected limiting section with pick box 3 and is made as arc-shaped structure, makes that cutting pick head 1 can explosion, and difficult drop-off surpasses existing domestic, international like product level application life.
