Problems solved by technology

[0003] The hammer heads in the existing sand making machines are all fixed by means of engagement. During the high-speed operation of the equipment, the hammer heads are prone to fall off, which poses a great safety hazard. At the same time, the existing hammer heads have limited mechanical strength. Most of the performance is not ideal, the service life is short

Abstract

The invention discloses a high-strength modified alloy hammer head for a sand making machine, relates to the technical field of sand making machine equipment, and mainly solves the problems that a conventional hammer head of the sand making machine is not firm in connection and low in mechanical strength. The high-strength modified alloy hammer head comprises a hammer body which adopts a cuboid structure, wherein a mounting hole is formed in the central position of the hammer body; a plurality of key slots are formed in positions, corresponding to the mounting hole, at the bottom of the hammerbody, and are formed in the periphery of the mounting hole in the circumferential direction at an equal distance; and a plurality of positioning assemblies are arranged in positions, corresponding tothe mounting hole, at the top of the hammer body, and are arranged at the periphery of the mounting hole in the circumferential direction at an equal distance. The master batch of the hammer head comprises the following components: 0.003-0.004% of tin, 1.19-1.21% of manganese, 3.40-3.44% of sodium chloride, 4.65-4.75% of chromium and the balance of iron. Through the adoption of the high-strengthmodified alloy hammer head disclosed by the invention, the connecting firmness between the hammer body and a transmission rod of the sand making machine can be greatly improved; besides, the mechanical strength of the hammer body is high.

Description

technical field [0001] The invention relates to the technical field of sand making machine devices, in particular to a high-strength metamorphic alloy hammer for a sand making machine. Background technique [0002] With the acceleration of economic construction and social development, the demand for sand is also increasing, and the phenomenon of random mining and excavation of river sand continues to appear, and measures to prohibit mining and excavation have been adopted in various places. Therefore, artificial sand making machines should be used The new type of sand making machine (vertical shaft impact crusher) is suitable for crushing soft or medium hard and extremely hard ore materials with a hardness not higher than 320Pa. Sand making machines are widely used in large, smelting, building materials, roads, railways , water conservancy and chemical industry and many other sectors. The hammer head is a sand making machine with integral structure, and the hammer head is d...
