Study on Bimetal Compound Casting Technology of Hammers

摘要

For the characteristics of the hammer handle is under bending stress and impact constantly alternating and the main of the hammer is Withstand strong impact and friction in use, the paper designed a new type of composite casting process of hammerhead. It has two wear block imbedding in the below of the hammer, and it set in on both sides of the axis of the hummer wiche with Inverted trapezoidal dovetail structure. The wear block was cast by high chromium cast iron, and it is properly heat treatment and surface cleaning before casting, but Into the mold after re-heated to temperature above 600°C, At the same time, poured into the cast high-manganese steel quickly, so the block and hammer handle fused together, the block of composite hammer does not wear off in the use, and the wear resistance of the hummer improved significantly.
