Trimetal composite cast crusher hammer production process method

Abstract

The invention relates to a cast crusher hammer production process and provides a trimetal composite cast crusher hammer production process method. The method includes: pouring low alloy steel or normal cast steel so as to form an internal hammer handle, preheating the internal hammer handle prior to enabling the internal hammer handle to form a composite hammer handle by pouring, pouring high-chromium cast iron so as to produce the composite hammer handle into a trimetal crusher hammer, casting a composite hammer handle position by a cladding method on the basis of an original double-liquid bimetal composite method, and compositing the composite hammer handle and a hammer end position by pouring the high-chromium cast iron. The external hammer handle is good in abrasion resistance, the internal hammer handle is made of materials good in toughness, and accordingly the hammer handle can bear high material abrasion to give full play to high abrasion resistance of the high-chromium cast iron, and the service life of the hammer is prolonged integrally.

Description

technical field [0001] The invention relates to a production process of the hammer head of a casting crusher, in particular to a three-metal composite casting crushing method that adopts a cladding method to form the composite hammer handle part of the hammer head, and combines the hammer end of the hammer head with the hammer handle by double-liquid metallurgy. Machine hammer head production process. Background technique [0002] The hammer head is an important part of the crusher, and it is also the part that consumes the most and is most easily damaged on the crusher, and consumes a lot. At present, most of the various types of traditional hammer heads used in domestic crushers are made of low alloy steel, high manganese steel or high chromium cast iron. However, due to the different working conditions between the hammer handle of the hammer head and the hammer end, the hammer handle is required to have a certain strength and toughness; the hammer end is the main wear pa...

AI Technical Summary

Problems solved by technology

[0003] This method solves the breakage or shedding phenomenon of the hammer head during use, but because the material first broken by the hammer end of the hammer head is smaller than the gap between the two hammer heads, the material will fall from the gap. The material will rub against the hammer handle, and the hammer head will be subjected to alternating bending stress and impact force during the crushing process, and the low alloy steel hammer handle will not be wear-resistant, showing "handle eating"
