example 1

[0031]A kind of mining hammer head, the casting material is carbon powder, manganese powder, iron powder, magnesium powder, aluminum powder and other rare metal powder, and its mass percentage is 1.5%, 12%, 81%, 1.5%, 2.5% respectively and 1.5%; the traditional sand box casting hammer does not add other rare metals, but the mass fraction of iron powder has increased. Pour the above two prepared powders into a horizontal spiral mixer and stir evenly, then pour the evenly stirred powder into an intermediate frequency melting furnace for melting, and finally cast the two molten melts into the improved sand box and the traditional sand box respectively. Two different mining hammer heads are cast in the box cavity. Among them, the related parameters of the improved sand box are as follows: the working frequency of the vibrator is selected from 10~120Hz, the rotation of the rotating platform is selected from the forward rotation, and the rotation speed is ω In the range of 0~0.5m / s...

Abstract

A method for casting a mine hammer is characterized by comprising the following steps that: firstly, carbon powder, manganese powder, iron powder, magnesium powder, aluminium powder and rare metal powder are poured into a horizontal screw mixer to be uniformly mixed, and the mass percents of the carbon powder, the manganese powder, the iron powder, the magnesium powder, the aluminium powder and the rare metal powder are respectively controlled to be 0.5-2%, 7-15%, 76-90%, 0.5-2%, 1-3% and 0.5-2%; secondarily, the uniformly mixed powder is poured into an intermediate frequency smelting furnace to smelt; thirdly, a moulding box for casting is installed on an excitation rotary combination action casting machine; and fourthly, the melt is cast into the cavity of the moulding box, meanwhile, an excitation motor, a lifting motor and a rotary motor are started, and the moulding box is subjected to multiple actions of excitation, vertical movement and rotation, so the melt is quickly, uniformly fed into the cavity, and the mine hammer with the impact toughness which is not less than 85.095J / m<2> is cast. The method is simple, is easy to realize, and has less casting defects, and the hardness and toughness of a casting are obviously improved.

Description

technical field [0001] The invention relates to a mining machinery accessory, in particular to a mining hammer, in particular to a casting method of the mining hammer. Background technique [0002] At present, there are various materials for mining hammer castings, but the service life is not ideal. Using some rare metal elements on the basis of the original ingredients can effectively improve the service life of mining hammers. In addition, the casting equipment is also Regarding the service life of the hammer head, there are still some deficiencies in the casting equipment currently used in the market, which are mainly reflected in the following aspects: First, the casting equipment is in a traditional static state, that is, the sand box is placed on a fixed plane, and the sand box is placed on a fixed plane. The casting box does not make any movement. It is difficult for this kind of casting equipment to discharge the air bubbles generated during casting during the actual...
