Description

A new hammer crusher hammer head

technical field

The utility model relates to a novel hammer crusher hammer head.

Background technique

Reversible hammer crusher is one of the main equipments for finely crushing limestone, coal or other brittle materials below medium hardness in metallurgy, building materials, chemical industry, hydropower and other industrial sectors. It has the characteristics of large crushing ratio, high production capacity, advanced structure, reliable performance, stable work, low energy consumption and uniform particle size. There are two types of hammer crushers: reversible and irreversible. The rotor of the reversible hammer crusher is reversible and is generally used for fine crushing; the rotor of the irreversible hammer crusher is irreversible and generally used for secondary crushing. After the machine has been used for a period of time, the working side of the hammer head has been worn out, and the lining plate and grate on the rotor side are also worn to a certain extent. At this time, the motor can be stopped and the motor reversed. At this time, the rotor is reversed, and the unworn side of the hammer head will be Become the working surface and utilize the unworn grate and liner on the other side. Once installed, the hammer head can be used on both sides, reducing installation time and improving work efficiency.

At present, one end of the hammer head of the prior art hammer crusher is a pin hole, which is hinged and suspended on the pin shaft of the rotor body, and the other end is used as the hammer head to strike the ore.

Utility model content

In order to solve the above problems, the utility model provides a novel hammer crusher hammer.

The technical solution adopted by the utility model to solve the technical problem is: a new type of hammer crusher hammer head, including hammer body, rib plate and ferrule, the ferrule is three, and evenly distributed on the circumference; The hammer body is made of high manganese steel, which is inlaid with three ferrules respectively; The three hammer bodies are connected as a base, the outer contour of the rib plate is an arc curve, and is tangent to the hammer body; the thickness of the rib plate is smaller than that of the hammer body.

Further, the thickness of the hammer body is equal to the length of the ferrule.

Further, the wall thickness of the ferrule is between 10mm and 20mm.

The beneficial effects of the utility model are: since the hammer body adopts a cylindrical structure, the line of impact force acting on the hammer body can basically pass through the center of the ring circle equivalent to the collision center, reducing vibration and noise, and prolonging the service life of the rotor bearing; Casting the ferrule into the high manganese steel matrix can effectively avoid the breakage of the hammer body; the three ferrules are evenly distributed, and each ferrule can be used as a pin hole to hinge with the rotor body pin, when used in reversible hammer On the crusher, both sides of the hammer body can strike ore, and its service life is considerably extended by six times, which greatly reduces the cost of use and improves economic benefits.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Fig. 1 is a structural representation of the utility model;

Figure 2 is a cross-sectional view of Figures 1A-A.

detailed description

As shown in Figures 1 and 2, a new type of hammer crusher hammer head includes a hammer body 1, a rib plate 3 and a ferrule 2, and there are three ferrules 2, which are evenly distributed on the circumference; The hammer body 1 uses high manganese steel as the matrix, and is cast into one body with three ferrules 3 respectively; the end surface profile of the hammer body 1 is circular, and the center of the circle is concentric with the ferrule 2; Using high manganese steel as the matrix, the three hammer bodies 1 are connected as a whole, and the outer contour of the rib plate 3 is an arc curve, which is tangent to the hammer body 1 .

In order to facilitate casting, the thickness of the rib plate 3 is smaller than that of the hammer body 1 .

The thickness of the hammer body is equal to the length of the ferrule.

In order to ensure the strength requirement, the wall thickness of the ferrule is between 10mm and 20mm.

The hammer body 1 is made of high manganese steel material with high hardness and certain wear resistance. The mass fraction of the chemical composition of the designed high manganese steel is: 1.16%～1.27%C, 13.06%～14.28%Mn, 0.52%～0.84% Si, 1.91%-2.43% Cr, 0.03%-0.05% S, 0.04%-0.06% P, 0.19%-0.25% Re, 80.82%-83.09% Fe.

The ferrule is made of medium carbon steel with high strength, good plasticity and toughness, and will not break under impact force.

Put the ferrule 2 into the lost foam, and pour the high manganese steel solution to make the two metallurgically bonded.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
