Further, the length of described alloy bar is 50-300mm, and width is 20-30mm, and thickness is 15-30mm.
Further, the length of described arc convex is the 1/3-2/3 of described alloy bar length.
Further, the central angle of described arc convex is 30-150 °.
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.
The thrower head that the utility model provides compared with prior art, has following beneficial effect:
1, the thrower head that provides of the utility model, wear-resistant, long service life.The thrower head 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 an arc convex, the two ends of described arc convex connect respectively a horizontal plane, the shape of described groove and the form fit of described alloy bar.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 2-3 service life doubly.
2, the thrower head 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 thrower head that the utility model provides, but because having 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.
3, the thrower head that provides of the utility model when improving the thrower head abrasion resistance properties, has reduced the production cost of alloy bar.This practical thrower head 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.

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, a kind of thrower head, 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 is an arc convex 4, and the two ends of arc convex 4 connect respectively a horizontal plane 5, the form fit of the shape of groove 2 and alloy bar 3.
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 2-3 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.
