Embodiment Construction

[0012] The present invention will be further described below in conjunction with the embodiment that accompanying drawing provides:

[0013] A hammer piece, a hammer piece matrix (1) made of ordinary steel, one end of the hammer piece is provided with a pin hole (2), the other end of the hammer piece is a crushing working end surface (3), and the working end surface (3) is carbonized It is made of wear-resistant materials such as tungsten, and the entire surface is carburized and hardened. It is characterized in that the front end of the hammer matrix (1) is welded with a scraper (4), and the scraper (4) is welded vertically to the hammer. The front ends are aligned, and at the front edge of the scraper blade (4), wear-resistant materials (5) are surfacing on the upper and lower sides, and the slope angle of the surfacing welding At 60 degrees, the height of the surfacing welding is 1 times the thickness of the hammer.

Abstract

The invention provides a pulverizer hammer slice and a manufacturing method thereof. The pulverizer hammer slice is characterized in that a scraping slice (4) is welded to the front end of a hammer slice matrix (1); the manufacturing method of the pulverizer hammer slice comprises the steps that the hammer slice matrix (1) and the scraping slice (4) are both provided with grooves at first, so that the hammer slice matrix (1) and the scraping slice (4) are welded together after being perpendicularly installed; and high-moisture high-fiber high-grease materials can be extruded out of sieve meshes through the hammer slice, so that the problem that the sieve meshes of a pulverizer are blocked by the high-moisture high-fiber high-grease materials is thoroughly solved.

Description

technical field [0001] The invention relates to a hammer used in a pulverizer and a manufacturing method thereof, especially used in a water drop pulverizer, a vertical pulverizer, a double rotor pulverizer, a multi-chamber pulverizer, a washboard pulverizer, a screenless pulverizer, etc. The above hammer and its manufacturing method. Background technique [0002] The hammer of the hammer mill in the prior art is in the shape of a rectangular sheet. The hammer is usually made of ordinary carbon steel as the matrix (1), and one end of the hammer is provided with a pin hole (2). Screws are connected with the rotor. The other end of the hammer is the crushing working end face (3). The working end face (3) is made of tungsten carbide and other wear-resistant materials. , adopt small iron plate to cover appropriately on the pin hole (1) surface, cover the dotted line that sees the pin hole (2) periphery in shape, have certain toughness and not be hardened to keep the pin hole (2...
