Abstract
The utility model discloses a throwing head for a crusher, which is composed of a metal base and a hard alloy bar, wherein an arc groove is arranged at the center of the bottom of the metal base; the hard alloy bar is in arc shape corresponding to the arc groove and adhered to the arc groove; the length of the hard alloy bar ranges from 50mm to 300mm; the width of the hard alloy bar ranges from 10mm to 20mm, the height of the hard alloy bar ranges from 8mm to 20mm, and the radian of the hard alloy bar ranges from 650 degrees to 850 degrees. The throwing head is resistant to abrasion and strong in anti-impact capacity. Since the arc abrasion-resistant alloy bar is used, the shape of the hard alloy bar in the throwing head is changed into arc shape from elongated shape, and the hard alloy bar can not eject out to hurt a machine body when the hard alloy bar is impacted. Under the condition of the same materials, area of effective working part is expanded, service life of the throwing head is prolonged and manufacturing and machining cost is reduced.
Description
Technical field
The utility model relates to a kind of disintegrating machine parts, is specifically related to a kind of wear-resisting material casting head that is used for disintegrating machine.
Background technology
The higher hardness material is in crushing processing process, and the material casting head that uses in the disintegrating machine plays main fragmentation.Be to carve at a material casting bottom centre position with elongated shape alloy bar edge as present employed material casting is first with one, in the broken material process, edge is carved at the alloy bar wearing and tearing ratio at a material casting bottom centre position very fast, impact resistance is poor, cause body injury easily after the alloy bar fracture, cause reduce service life, and bring higher cost to production and processing.Therefore the improvement of material casting head becomes key problem in technology.
Summary of the invention
The purpose of this utility model is to solve an existing material casting quick abrasion, impact resistance is poor, service life is short and the production and processing cost is high shortcoming, and a kind of wear-resistant, strong shock resistance, long service life and the low disintegrating machine of production and processing cost material casting head are provided.
The utility model for the technical scheme that solves above-mentioned technical disadvantages and adopt is: the disintegrating machine material casting head of being made up of metallic matrix and carbide alloy bar, it is characterized in that: the bottom centre of described metallic matrix is provided with arc groove, and the carbide alloy bar is corresponding arc and is bonded in the arc groove with glue; The length of described carbide alloy bar is 50-300mm, and wide is 10-30mm, and height is 8-20mm, and radian is 650-850 °.
In order better to realize this purpose, the back side of the working face of carbide alloy bar inwardly becomes the inclined-plane, and this bevel angle is 3 °-85 °.
The utility model is wear-resistant, strong shock resistance.Owing to adopted arc antifriction alloy bar, the shape of the carbide alloy bar in the material casting head is become arc by elongated shape, the carbide alloy bar can not eject the damage body when being subjected to impacting.Under the condition of equal material, increase the area of effective working position, prolonged the service life of material casting head, reduced the production and processing cost.
The back side of the working face of arc wearable hard alloy bar is inwardly become inclined design, reduced the weight of the area and the alloy bar of non-working surface, reduced cost, also can prolong the service life of material casting head simultaneously; Under the condition of taking identical material, increased the area of effective working position, prolonged the material casting head service life 2-3 doubly.
