[0033] The utility model discloses a description below Figures 1-4 And through specific mode of implementation to further explain the technical scheme of the utility model.

[0034] One preferred embodiment in the application, a kind of high-strength crusher cast steel parts, the crusher cast steel part includes lining plate main body 1, several installation grooves 2, several impact blocks 3, installation portion 4, several reinforcing ribs 5 and several threaded through holes 6;The threaded through hole 6 is close to the installation groove 2 and is arranged in the lining plate main body 1, the impact block 3 is fixed in the lining plate main body 1 by the threaded through hole 6 with bolt;Several reinforcing ribs 5 are arranged in the interior of the lining plate main body 1;

[0035] The working surface of the lining plate main body 1 is provided with the installation groove 2, and each impact block 3 is installed in the corresponding installation groove 2;The back surface of the lining plate main body 1 is provided with the installation portion 4.

[0036] Specifically, the liner body 1 as the main force component, the inside is provided with the reinforcing rib 5. The reinforcing rib 5 is used to enhance the structural strength of the liner body 1, so that the liner body 1 can withstand greater impact force without being easily deformed or broken, the impact block 3 is a component for directly crushing materials in the crusher, the top of the impact block 3 is provided with a high-strength and impact-resistant working part for directly crushing materials, the mounting groove 2 is provided with an opening area, the size of the opening area is smaller than the internal receiving space of the mounting groove 2, the main body of the impact block 3 is installed in the internal receiving space, the threaded through hole 6 is arranged on the liner body 1 close to the opening area, the impact block 3 is fixedly connected with the liner body 1 through the threaded through hole 6 and the bolt, by tightening the bolt, the bolt presses and extrudes the impact block 3 to prevent the impact block 3 from deviating during work. The combination of the threaded through hole 6 and the bolt ensures that the impact block 3 will not loosen or fall off during work, thereby ensuring the stability and safety of the crusher. At the same time, the impact block 3 can be replaced and installed by disassembling the bolt, which is simple and convenient to operate, and reduces downtime maintenance time. The back of the liner body 1 is provided with the mounting part 4, which is to facilitate the installation of the entire cast steel part on the body of the crusher. The design of the mounting part 4 considers the connection mode and fastening requirements of the crusher body to ensure that the cast steel part can be stably fixed on the crusher body during work. Since the reinforcing rib 5 strengthens the structural strength of the liner body 1, and the impact block 3 is detachably installed on the liner body 1, such design not only can significantly reduce the wear of the liner body 1 and prolong the service life, but also can reduce the frequency of replacing the liner, reduce downtime and maintenance cost. The technical scheme solves the problems of easy wear, deformation and even fracture of the traditional crusher liner.

[0037] It should be noted that the liner body 1 is a cast steel part, in order to improve the mechanical properties of the liner body 1, the liner body 1 needs to be subjected to heat treatment process: (1) preheating, uniformly heating the liner body 1 to the austenite zone to eliminate internal stress generated during casting; (2) quenching: cooling treatment, cooling the liner body 1 to the bainite zone and carrying out isothermal holding; (3) tempering: heating the quenched liner body 1 to a certain temperature and keeping for a period of time, and then cooling to adjust the hardness and strength of the liner body 1.

[0038] In an optional embodiment, the mounting groove 2 comprises a first mounting sub-groove 21, a second mounting sub-groove 22, and a third mounting sub-groove 23. The first mounting sub-groove 21 and the second mounting sub-groove 22 are symmetrically arranged on the left and right sides of the mounting groove 2, and the third mounting sub-groove 23 is arranged at the bottom of the mounting groove 2. In the vertical direction, the cross-sectional width of the top of the third mounting sub-groove 23 is smaller than that of the bottom of the third mounting sub-groove 23.

[0039] Specifically, the first mounting sub-groove 21 and the second mounting sub-groove 22 are symmetrically arranged on the left and right sides of the mounting groove 2, and the mounting sub-grooves on the left and right sides can provide two symmetrically arranged mounting spaces. When stressed, the objects mounted in the two symmetrically arranged mounting spaces can jointly bear the force, thereby reducing stress concentration and the risk of deformation and damage. In the vertical direction, the cross-sectional width of the top of the third mounting sub-groove 23 is smaller than that of the bottom of the third mounting sub-groove 23. This design can enable the bottom to provide better support and fixation when the impact block 3 is mounted. At the same time, since the cross-sectional width of the third mounting sub-groove 23 gradually increases from the top to the bottom, the force borne by the impact block 3 can be more evenly distributed on the entire mounting groove 2 during use. This can not only improve the carrying capacity but also prolong the service life.

[0040] In an optional embodiment, the impact block 3 comprises a first side wing 31, a second side wing 32, a conical base 33, a connecting portion 34, and an impact head 35. The first side wing 31 and the second side wing 32 are respectively arranged on the left and right sides of the top of the conical base 33. The bottom of the connecting portion 34 is arranged on the top of the first side wing 31 and the second side wing 32. The impact head 35 is arranged on the top of the connecting portion 34.

[0041] Specifically, when the impact block 3 is mounted in the mounting groove 2, the first side wing 31 is mounted in the first mounting sub-groove 21, the second side wing 32 is mounted in the second mounting sub-groove 22, and the conical base 33 is mounted in the third mounting sub-groove 23. When stressed, the first side wing 31 and the second side wing 32 on the left and right sides can jointly bear the force, thereby reducing stress concentration and the risk of deformation and damage. The design of the conical base 33 makes the bottom of the impact block 3 more stable and can provide better support and fixation. At the same time, the conical shape can effectively disperse the impact force, reduce the wear of the bottom, and improve the service life. The impact head 35 is located at the top of the impact block 3, which can ensure that the impact head 35 bears the impact of the material during work and can replace and maintain the impact block 3 according to the wear of the impact head 35.

[0042] In an alternative embodiment, the impact head 35 is in the shape of a frustum, and the cross-sectional area of the bottom of the impact head 35 is larger than the cross-sectional area of the top of the impact head 35.

[0043] Specifically, when the material impacts the impact head 35, the impact force can be concentrated due to the smaller cross-sectional area of the top of the impact head 35, and the breaking capacity is enhanced, and the material is more easily broken into smaller particles. At the same time, the impact head 35 will bear a large impact force and wear during the breaking process, but the design of the frustum shape helps to reduce the degree of wear. Due to the smaller cross-sectional area of the top, the contact area of the impact head with the material during the breaking process is also reduced, thereby reducing the wear caused by friction.

[0044] In an alternative embodiment, the first side wing 31 is fixed to the first mounting sub-slot 21 through the threaded through hole 6 and a bolt, and the second side wing 32 is fixed to the second mounting sub-slot 22 through the threaded through hole 6 and a bolt.

[0045] Specifically, the bolt can provide a high-strength connection effect. Through the fastening action of the bolt, the first side wing 31 and the second side wing 32 can be firmly fixed in the first mounting sub-slot 21 and the second mounting sub-slot 22, respectively, and are not prone to loosening or falling off. In the impact environment, the bolt connection can ensure the stability of the impact block 3 in the mounting slot 2, and reduce the risk of loosening due to vibration.

[0046] In an alternative embodiment, the material of the impact block 3 is white cast iron.

[0047] Specifically, white cast iron is known for its high strength and high hardness. In the impact breaking operation, the impact block 3 needs to bear a huge impact force and wear, so it must have sufficient strength and hardness to ensure its stability and durability. The high strength characteristic of white cast iron enables the impact block 3 to maintain its structural integrity in harsh working environments and is not prone to deformation or rupture. During the impact breaking process, frequent friction and collision occur between the impact block 3 and the material, which requires the impact block 3 to have excellent wear resistance to prolong its service life. Another notable feature of white cast iron is its wear resistance, which enables the impact block 3 to maintain the smoothness of its surface and the shape accuracy during long-term operation.

[0048] It should be noted that the white cast iron has high strength, high wear resistance, excellent impact resistance and good toughness by the following process: the white cast iron is heated to the austenite zone, then rapidly cooled to the bainite zone for isothermal holding, so that the matrix structure of the white cast iron is transformed into bainite, and the eutectic carbide is distributed in a spherical shape; this step can significantly improve the impact toughness of the white cast iron. The white cast iron subjected to isothermal quenching is tempered to eliminate quenching stress and improve plasticity and toughness.

[0049] In an optional embodiment, the mounting groove 2 and the impact block 3 are transversely arranged on the working surface of the liner body 1.

[0050] Specifically, the transversely arranged mounting groove 2 and impact block 3 can optimize the crushing path, so that the material can pass more smoothly during crushing, reducing the reduction of crushing efficiency caused by blockage or accumulation. At the same time, since the impact block 3 is transversely arranged, the impact block 3 can crush the material in a wider range, improving the crushing efficiency.

[0051] In an optional embodiment, the reinforcing rib 5 is longitudinally arranged inside the liner body 1.

[0052] Specifically, the longitudinal arrangement of the reinforcing rib 5 can significantly enhance the impact resistance of the liner body 1 in the longitudinal direction. When the impact block 3 is impacted by the material, the reinforcing rib 5 can effectively disperse and transmit the impact force, preventing the liner body 1 from deforming or breaking.

[0053] In an optional embodiment, the mounting portion 4 is two longitudinally parallel arranged grooves 41.

[0054] Specifically, the longitudinally parallel arranged grooves 41 make it easier to install with the fixed components of the crusher, thereby simplifying the installation process. At the same time, the longitudinally parallel arranged grooves 41 can provide stable support points for the installation of the liner body 1, ensuring that the liner body 1 can be firmly fixed in the desired position during installation.

[0055] In an optional embodiment, the groove 41 includes at least two fixing blocks 42, one of which is installed at one end of the groove 41, and the other of which is installed at the other end of the groove 41.

[0056] Specifically, the two fixing blocks 42 are respectively installed at both ends of the groove 41, serving as fixing and supporting. This helps to prevent displacement of the fixed components of the crusher during use, thereby ensuring the stability of the entire structure. At the same time, the fixing blocks 42 can disperse stress and reduce stress concentration at the connection between the mounting portion 4 and the crusher, thereby improving its carrying capacity.

[0057] The above has carried out the detailed introduction to the embodiment of the utility model, the principle and implementation mode of the utility model have been described in this paper with specific examples, the above embodiment is only used for helping understanding the method and its core idea of the utility model; simultaneously, for the general technical personnel of the field, according to the idea of the utility model, there will be changes in specific implementation mode and application range, and the above is described, the content of the specification should not be understood as the limitation of the utility model.
