Bi-metal hammer head and casting process thereof

Abstract

The invention discloses a bi-metal hammer head and a casting process thereof. The hammer head comprises a hammer head body and a hammer handle connected with the former, wherein a wear-resistant area is arranged at the joint of the hammer handle and the hammer head body and is extended, in a downward oblique cutting manner, from the hammer head body to the root part of the hammer handle. The casting process comprises the following steps: first, low alloy steel or common cast steel is filled in a sprue of the hammer handle to cast a hammer handle; and then, when the steel liquid in the hammer handle is near the composite interface of the hammer handle and the hammer head body, filling high-chromium iron or high alloy steel into a sprue of a hammer head body after 3-20s, so as to cast a hammer head body. According to the invention, a double-liquid bi-metal composite casting method is adopted to produce a hammer type hammer head, the working surface has very high wear resistance, the hammer handle part of a traditional hammer head is more resistant to wear; and meanwhile, the hammer handle part has favorable impact ductility, so that the characteristics of all materials are fully utilized, thereby prolonging the service life of the hammer head.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of crushers. It specifically relates to a bimetallic hammerhead and its casting process. Background technique [0002] The hammer head is an important part of the crusher, and it is also the most consuming and easily damaged part on the crusher. The consumption is huge, mainly due to the different working conditions of the hammer handle and the hammer end. The material of the handle has a certain strength and toughness, and the hammer head is the main wear part, which requires the material of the hammer head to have high wear resistance, but in the actual use process, the broken material will also cause damage to the hammer handle. A certain shock. see figure 1 , Under long-term repeated action, especially the hammer handle near the end of the hammer will have a large area of ​​wear. Contents of the invention [0003] The object of the present invention is to provide a bimetallic ...
