Description

A durable double metal composite crusher hammer head

technical field

The utility model relates to a crusher industry, in particular to a durable double metal composite crusher hammer head.

Background technique

Hammer crusher is a production equipment widely used in industrial sectors such as building materials, metallurgy, and chemical fertilizers. The hammer head is a wearable part with a large consumption. The hammer head is the contact between the working surface and the material, resulting in high-stress wear. Generally, it is hard objects such as rocks and metal ores, and the wear of the parts is relatively serious. However, most of the common high manganese steel hammer heads or high manganese steel plus surfacing hammer heads on the market are all-in-one hammer heads, and the preparation cost is relatively high. High, and the service life is generally short, and the replacement frequency is high, which affects production efficiency.

Utility model content

The main technical problem to be solved by the utility model is to provide a durable double metal composite crusher hammer head, which can have the performance of high hardness, high wear resistance and impact resistance, and has strong overall durability.

In order to solve the above technical problems, a technical solution adopted by the utility model is to provide a durable bimetallic composite crusher hammer head, including: an upper hammer part, a lower hammer part and a striking part, and the top of the lower hammer part passes through The cylindrical pin is connected with the bottom end of the upper hammer part, the bottom end of the lower hammer part is provided with a dovetail-shaped groove, and the top end of the striking part is provided with a dovetail-shaped protrusion, and the dovetail-shaped protrusion is embedded in the in the dovetail groove.

In a preferred embodiment of the present invention, the material of the striking part is KmTBCr26, and the hardness of KmTBCr26 is used to ensure the wear resistance of the striking part and further improve the service life.

In a preferred embodiment of the present invention, the materials of the upper hammer part and the lower hammer part are both ZG35, and the toughness of the ZG35 material ensures the fatigue resistance of the upper hammer part and the lower hammer part during use , to prevent breakage.

In a preferred embodiment of the present invention, the mosaic connection between the dovetail-shaped protrusion and the dovetail-shaped groove is realized by casting.

The beneficial effects of the utility model are:

1. By using cylindrical pins to realize the connection between the upper hammer part and the lower hammer part, when the hammer head needs to be replaced during the use of the crusher, it is only necessary to remove the lower hammer part, saving man-hours and improving production. efficient;

2. Compared with the traditional one-piece hammer head, by adopting the combined connection of the striking part at the lower hammer part, the durability is better and the production cost is also lower. This makes the connection between the lower hammer part and the striking part more stable, and it is less likely to fall off during use, further improving the durability.

Description of drawings

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

The mark of each part is as follows in the accompanying drawing: 1, upper hammer portion, 2, lower hammer portion, 3, striking portion, 4, dovetail groove, 5, dovetail protrusion, 6, cylindrical pin.

detailed description

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, so that the protection scope of the utility model can be defined more clearly .

Please refer to Fig. 1, the utility model embodiment is:

A type of composite crusher hammer head, comprising: an upper hammer part 1, a lower hammer part 2 and a striking part 3, the top end of the lower hammer part 2 is connected to the bottom end of the upper hammer part 1 through a cylindrical pin 6, The bottom end of the lower hammer part 2 is provided with a dovetail-shaped groove 4, and the top end of the striking part 3 is provided with a dovetail-shaped protrusion 5, and the dovetail-shaped protrusion 5 is embedded in the dovetail-shaped groove 4, The embedded connection between the dovetail protrusion 5 and the dovetail groove 4 is realized by casting.

Wherein, the material of the striking part 3 is KmTBCr26, and the hardness of KmTBCr26 is used to ensure the wear resistance of the striking part and further improve the service life.

Both the upper hammer part 1 and the lower hammer part 2 are made of ZG35, and the toughness of the ZG35 material ensures the fatigue resistance of the upper hammer part 1 and the lower hammer part 2 during use and prevents fracture.

Different from the prior art, the utility model uses cylindrical pins to realize the connection between the upper hammer part and the lower hammer part. When the hammer head needs to be replaced during the use of the crusher, only the lower hammer part needs to be removed. That is, it saves man-hours and has high production efficiency; compared with the traditional one-piece hammer head, the durability is better and the production cost is lower by using the combined connection of the striking part at the lower hammer part. The dovetail-shaped connection structure is adopted between the lower hammer part and the striking part to make the connection more stable, and it is less likely to fall off during use, further improving the durability.

The above is only an embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process conversion made by using the utility model specification and accompanying drawings, or directly or indirectly used in other Related technical fields are all included in the patent protection scope of the present utility model in the same way.
