Fabrication technology of wear-resistant hammer

Abstract

Provided is a fabrication technology of a wear-resistant hammer. The hammer is composed of two materials, a hammer handle is made of low carbon alloy steel, a hammer head is made of high-chromium iron, an upper part of a prepared hammer handle is placed in a slag bath of a water-cooling crystallizer, and a lower part of the hammer handle is located at the bottom of the crystallizer. The method comprises the following steps: (1) slag is melted into liquid state, and (2) liquid-state slag is cast into the hammer head. According to the fabrication technology of the wear-resistant hammer, product metal purity and product combined strength are high, crystal structure is compact, and technical process is stable and easy to control.

Description

technical field [0001] The invention relates to the field of metal material tools, in particular to a manufacturing process of a wear-resistant hammer. Background technique [0002] Plasma arc cutting is a cutting method that uses high-temperature, high-speed plasma and its flame to melt, evaporate and gasify the workpiece material and blow it away from the substrate. When cutting metal with small thickness, the cutting speed is fast, the cutting surface is smoother, and the thermal deformation is small, but the incision width is large. When cutting stone with a thickness of 150mm, the incision width is as high as 10-20mm. Therefore, when cutting stone (200≤thickness≤500mm), the cutting seam will be wider, and even cannot be cut normally. High-pressure water jet cutting equipment can shape and cut some metal and non-metal materials, but the cutting thickness is limited, and it cannot cut stone thick plates. Diamond bead saw is a diamond bead saw that fixes diamond abrasive...
