Further, the length of described horizontal plane is the 1/3-2/3 of described alloy bar length.
Further, the back side of described alloy bar working face is trapezoidal shape, and described two trapezoidal hypotenuses are positioned at the two ends of alloy bar length direction.
Further, the back side of described alloy bar working face is stepped.
Further, the length of described alloy bar is 50-300mm, and width is 20-30mm, and thickness is 15-20mm.
The sand machine thrower head processed that the utility model provides compared with prior art, has following beneficial effect:
1, the sand machine thrower head processed that provides of the utility model, wear-resistant, long service life.The sand machine thrower head processed that the utility model provides, comprise matrix and alloy bar, described matrix bottom is provided with groove, the described alloy bar of bonding in described groove, the centre of described alloy bar working face is a horizontal plane, the two ends of described horizontal plane connect respectively an inclined-plane, the shape of described groove and the form fit of described alloy bar.This alloy bar is trapezium structure, has increased the thickness of alloy bar, when thrower head is subjected to material impact, cause has effectively increased the work area of alloy bar thickness direction, but the wearing-in period of alloy bar is increased, and has extended the service life of thrower head, compared with prior art, extend 1.5-2 service life doubly.
2, the sand machine thrower head processed that provides of the utility model effectively reduces the operating cost of sand machine processed.Thrower head is the important component part of sand machine processed, is also the topmost consumptive material of sand machine processed.The sand machine thrower head processed that the utility model provides, but because having increased the wear-thickness of alloy bar, extended the service life of thrower head, when sand machine operation processed, reduced the replacement frequency of thrower head, thereby reduced the operating cost of sand machine processed.
3, the sand machine thrower head processed that provides of the utility model when improving the thrower head abrasion resistance properties, has reduced the production cost of alloy bar.This practical sand machine thrower head processed that provides, the back side of alloy bar working face is trapezoidal shape or stepped, because not wearing and tearing at the back side of alloy bar working face, and position centered by the position of alloy bar wearing and tearing, adopt trapezoidal or step structure, can realize reducing the use amount of alloy under the prerequisite that guarantees the alloy bar wearability, reduce the production cost of alloy bar, and alleviated the weight of alloy bar.

Reference numeral: 1-matrix, 2-groove, 3-alloy bar, 4-alloy bar working face, the back side of 5-alloy bar working face.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The specific embodiment:
In conjunction with Fig. 1 to Fig. 6, sand machine thrower head processed, comprise matrix 1 and alloy bar 3, matrix 1 bottom is provided with groove 2, the interior binder alloy bar 3 of groove 2, the centre of alloy bar working face 4 is a horizontal plane, and the two ends of horizontal plane connect respectively an inclined-plane, the shape of groove 2 and the form fit of alloy bar.
Groove 2 adopts the glue bonding with the bonding mode of alloy bar 3, and alloy bar and groove of substrate are closely cooperated.The shape of this alloy bar has increased the thickness of alloy bar, when thrower head is subjected to material impact, because effectively having increased the work area of alloy bar thickness direction, but the wearing-in period of alloy bar is increased, extend the service life of thrower head, compared with prior art, extended 1.5-2 service life doubly.But because increased the wearing-in period of alloy bar, extended the service life of thrower head, when sand machine operation processed, reduced the replacement frequency of thrower head, thereby reduced the operating cost of sand machine processed.
Preferably, the horizontal plane length of alloy bar working face 4 is the 1/3-2/3 of alloy bar length, the scope of this length is the frayed scope of alloy bar, the frayed segment thickness of alloy bar working face is increased, and not frayed part is horizontal plane, can reduce the alloy consumption that alloy bar is produced, reduce production costs.
