Embodiment Construction
[0015] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0016] As shown in the figure, a high-chromium cast iron hammer head includes a hammer handle 1 and a hammer body 2 connected to the bottom of the hammer handle 1. The hammer handle 1 is arranged on the upper part of the hammer head, and the hammer body 2 is arranged on the lower part of the hammer head. 2 is a trapezoidal block with a narrow top and a wide bottom. The trapezoidal angle of the hammer body 2 is 12°-25°. The lower end of the hammer handle 1 and the upper end of the hammer body 2 are respectively provided with through holes with the same diameter and size, and a shaft pin 3 is installed in the through holes. The shaft pin 3 connects the hammer handle 1 with the hammer body 2, and the end of the hammer handle 1 away from the hammer body 2 is provided with a mounting hole 4, and the hammer handle 1 is connecte...

The invention discloses a high chromium cast iron hammer which comprises a hammer handle and a hammer body connected to the bottom of the hammer handle. The hammer handle is arranged on the upper portion of the hammer. The hammer body is arranged on the lower portion of the hammer and is in the shape of a trapezoidal block with the top being narrow and the bottom being wide. The trapezoidal angle of the hammer body is 12-25 degrees. The lower end of the hammer handle and the upper end of the hammer body are separately provided with through holes of the same diameter. The through holes are internally provided with shaft pins which connect the hammer handle and the hammer body. The end, away from the hammer body, of the hammer handle is provided with a mounting hole. The hammer handle is connected to crushing equipment through the mounting hole. By adoption of the high chromium cast iron hammer, abrasion resistance of the hammer body can be improved, prolonging of the service life of the hammer is facilitated, the replacing frequency is reduced, production cost of an enterprise can be further reduced, and working efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of mine crushing mechanical devices, and in particular relates to a high-chromium cast iron hammer head. Background technique [0002] Crusher is widely used in mining, metallurgy, electric power and other industries. It mainly uses the high-speed rotating hammer head to collide with the material to break the material. The hammer head is the key part and the part that is most prone to wear and tear. Therefore, the crusher The consumption of the hammerhead is huge. There are many types of crusher hammerheads on the market at present. The accurate definition of the hammerhead should be the hammerhead of the hammer crusher. The hammerhead is one of the core components of the hammer crusher. On the hammer shaft of the crusher rotor, the hammer head directly hits the material when the crusher is running at high speed, and finally crushes the material into a suitable particle size. [0003] Crusher hammers on the...
