Electroslag cast combined double-metal double-surface hammer and manufacturing method thereof

Abstract

The invention discloses an electroslag cast combined double-metal double-surface hammer and a manufacturing method thereof. The electroslag cast combined double-metal double-surface hammer comprises a hammer body, wherein a rectangular hole is formed in the middle of the hammer body, gaps are formed in the positions, corresponding to the two sides of the rectangular hole, on the hammer body, and pin holes communicated with the rectangular hole and used for being connected with combined hammer handles are formed in the positions, corresponding to the gaps, on the hammer body. The electroslag cast combined double-metal double-surface hammer is characterized in that the distance between the upper end face of the rectangular hole and the corresponding upper end face of the hammer body ranges from 5mm to 10mm, the distance between the lower end face of the rectangular hole and the corresponding lower end face of the hammer body ranges from 5mm to 10mm, a boss with the height ranging from 10mm to 20mm is arranged in the middle of the upper end face and the middle of the lower end face of the hammer body, the cross section of the boss is a rectangle, the distance between the edge of the boss and the edge of the corresponding upper end face of the hammer body ranging from 15mm to 30mm, the distance between the edge of the boss and the edge of the corresponding lower end face of the hammer body ranging from 15mm to 30mm, high-chromium iron wearing layers formed by electroslag casting are arranged on the upper end face and the lower end face of the hammer body, and emptying grooves are formed in the high-chromium iron wearing layers. The electroslag cast combined double-metal double-surface hammer has the advantages of being safe to use, free of breakage, good in wear-resisting property and capable of reducing production and usage cost.

Description

technical field [0001] The invention relates to a metal double-sided hammer head used in a hammer crusher, in particular to a carbon steel and high-chromium cast iron combined double-metal double-sided hammer head made of carbon steel and high chromium cast iron through an electroslag melting method and a manufacturing method thereof. Background technique [0002] At present, most of the hammer heads used in fine crushing crushers for pulverizing coal gangue and shale are combined double-sided square hammer heads. The hammer heads can be used four times in front and back to fail, and the comprehensive utilization is better. This kind of hammer head is mainly made of high manganese steel and medium carbon or low carbon wear-resistant alloy steel. It is frequently replaced in use, the consumption of the hammer head is large, the labor intensity of workers is high, the productivity is low, and the use cost is high. The hammer head made of wear-resistant alloy steel also has the...

Problems solved by technology

This kind of hammer head is mainly made of high manganese steel and medium carbon or low carbon wear-resistant alloy steel. It is frequently replaced in use, the consumption of the hammer head is large, the labor intensity of the workers is high, the productivity is low, and the cost of use is high.

The hammer head made of wear-resistant alloy steel still has the safety problem of insufficient toughness and easy breakage
