Description

Technical Field

[0001] This utility model belongs to the field of crusher hammer technology, specifically, it relates to a wear-resistant hammer. Background Technology

[0002] When an impact crusher is working, the hammers held on the rotor component strike the incoming stone. The broken stones bounce back onto the impact frame, and the stones bounce back again after hitting the impact frame. The hammers strike the stone again, turning large stones into smaller particles. The hammers are easily worn down in this process, and the impact force of the hammers on the stone affects the degree of stone fragmentation. In order to improve the impact force of the hammers on the stone, a wear-resistant hammer is provided. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses a wear-resistant hammer head, including: a hammer head; the hammer head is a long strip block, with protruding retaining strips and hammering parts on both sides, and lifting holes and limiting holes on the end faces of both ends, the retaining strips and hammering parts are symmetrically arranged about the central axis of the lifting holes, and hammering teeth are provided on the side of the hammering parts.

[0005] Furthermore, the cross-section of the aforementioned card strip is angular.

[0006] Furthermore, the side of the aforementioned hammering part is provided with two hammering teeth, one upper and one lower, and a protruding strip is provided between the hammering teeth.

[0007] Furthermore, the cross-sectional edge of the aforementioned protrusion is arc-shaped.

[0008] Furthermore, the hammerhead mentioned above is made of high manganese steel.

[0009] Compared with the prior art, this application can achieve the following technical effects: This invention features hammering sections on the upper and lower edges of both sides of the hammerhead, increasing its weight and enhancing the impact force. The hammering teeth on the hammering sections have edges that can act as impact blades, reducing the impact on the stone from surface contact to line contact, thereby increasing the destructive force and crushing efficiency.

[0014] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0015] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the cross-section of a crusher according to one embodiment of the present invention; Figure 2 This is a schematic diagram of the rotor component and hammer head installation according to one embodiment of the present invention; Figure 3 This is a schematic diagram of a hammer head according to one embodiment of the present invention.

[0016] The impact crusher has a body 6, inside which are a first impact frame 10, a second impact frame 11, a third impact frame 12, a rotor assembly 13, hammers 14, and liners. The liners are fixed to the inner wall of the crushing chamber of the body 6. The first impact frame 10, the second impact frame 11, and the third impact frame 12 are arranged sequentially from top to bottom in the crushing chamber of the body 6, surrounding the rotor assembly 13. The hammers 14 are installed on the rotor assembly 13. The stone material fed into the crushing chamber is hammered onto the impact frame by the rotating hammers 14, and crushed into stone particles.

[0017] The rotor component 13 has multiple mounting slots around its perimeter. One side of the mounting slot has a limiting seat 131, and the other side has a fixing seat 132, a limiting top seat 133, and a limiting block 134. The hammer 14 is placed between the limiting seat 131 and the limiting top seat 133. The retaining strip 1 on one side of the hammer 14 engages with the retaining groove on the limiting seat 131. The bottom surface of the limiting seat 131 abuts against the hammering part 2 at the bottom of the hammer 14. The limiting block 134 is locked between the limiting top seat 133 and the hammer 14. The retaining groove on the limiting block 134 engages with the retaining strip 1 on one side of the hammer 14. The screw passes through the limiting block 134 and connects to the fixing seat 132, thereby locking the hammer 14 onto the rotor component 13.

[0018] A wear-resistant hammerhead includes: a hammerhead 14; the hammerhead 14 is a long strip block, commonly known as a plate hammer, with protruding retaining strips 1 and hammering parts 2 on both sides, and lifting holes 3 and limiting holes 4 on the end faces of both ends, the retaining strips 1 and hammering parts 2 are symmetrically arranged about the central axis of the lifting holes 3, and hammering teeth 5 are provided on the side of the hammering parts 2.

[0019] The cross-section of the clip 1 is an isosceles pointed angle, and the clip 1 serves as a limit.

[0020] The lifting hole 3 is used for hoisting the hammer head 14 by the hoisting machinery. The limiting hole 4 is used to prevent the hammer head 14 from rotating randomly when the hammering end is flipped. The limiting rod is inserted into the hoisting machinery arm and the limiting hole 4 at the same time to limit the movement. The hammer head 14 is a flip-type dual-purpose hammer head. After one end is worn, the other end can be flipped and used.

[0021] The side of the hammering part 2 is provided with two hammering teeth 5, one above the other, and a protruding strip 7 is provided between the hammering teeth 5. The cross-sectional edge of the protruding strip 7 is arc-shaped. When the protruding strip 7 comes into contact with the stone, it forms oblique friction, which causes the stone to collide with the hammering teeth 5. The edge of the hammering teeth 5 increases the impact force by making line contact, thereby improving the efficiency of crushing stone.

[0022] Hammer head 14 is made of high manganese steel. High manganese steel has excellent toughness and is suitable for crushing stone containing impurities. However, it needs to be "cold-worked" to achieve wear resistance. Cold-worked is a process of "plastic deformation → microstructure strengthening → macro performance improvement". It does not require heat treatment and can achieve surface strengthening of the material only through mechanical force.

[0023] This invention provides hammering parts 2 on the upper and lower edges of both sides of the hammerhead 14 to increase its weight and enhance the impact force of the hammering. The hammering teeth 5 provided on the hammering parts 14 can become impact blades, reducing the impact on the stone from surface contact to line contact, thereby increasing the destructive force of the impact and improving the crushing efficiency.

[0024] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
