Description

Technical Field

[0001] This invention relates to the field of wear-resistant hammerhead heat treatment technology, specifically a wear-resistant hammerhead heat treatment system for crushers. Background Art

[0002] Wear-resistant hammerheads are key components installed on equipment such as crushers and are widely used in industries such as mining, building materials, and metallurgy. In order to ensure that wear-resistant hammerheads have good toughness and a certain degree of wear resistance during the production process, the wear-resistant hammerhead material needs to be heat-treated.

[0003] During the heat treatment process, the wear-resistant hammerhead first needs to be heated to over 1000 degrees Celsius, then held at that temperature to ensure uniform heating. Next, it undergoes quenching, which involves rapidly cooling the hammerhead to maintain its hardness and wear resistance. Finally, it is tempered to further improve its toughness and strength.

[0004] In the above process, when the hammerhead is quenched, it is necessary to use hoisting equipment to transfer the heated hammerhead. Since the hammerhead is not large, the efficiency of hoisting it individually is low. Usually, hoisting equipment is used to hoist a transfer rod, and the hammerheads are arranged on the transfer rod to achieve the overall position transfer of the hammerhead. During this process, the distance between the hammerheads is small. If the hoisting equipment vibrates during the transfer, it will cause collisions between adjacent hammerheads. In addition, because the hammerhead has been fully heated during this process, it is very easy for the hammerhead to deform, which will affect the machining accuracy of the hammerhead. Summary of the Invention

[0005] The purpose of this invention is to provide a heat treatment system for wear-resistant hammerheads of crushers.

[0006] The technical problem solved by this invention is to address the deformation problem caused by collisions between hammers during the heating and quenching process in the prior art.

[0007] The present invention can be achieved through the following technical solution: a wear-resistant hammer heat treatment system for a crusher, including a lifting rod for hoisting the hammer body, a number of sets of limiting grooves are evenly opened on the lifting rod, and a retractable push plate for separating the hammer body is slidably arranged inside the limiting groove, and the retractable push plate can extend out of the lifting rod.

[0008] A further technical improvement of the present invention is that a limiting sliding base is fixedly installed inside the hanger rod, a limiting push plate is slidably arranged on the limiting sliding base, and the limiting push plate and the retracting push plate are fixedly connected.

[0009] A further technical improvement of the present invention is that: an internal fixed base for sliding and limiting the retraction push plate is fixedly fitted inside the hanger rod, and an end sliding base is slidably provided on the internal fixed base through a push spring, and the end sliding base and the retraction push plate are fixedly connected.

[0010] A further technical improvement of the present invention is that: a hinge rod is rotatably provided on the limiting push plate, the other end of the hinge rod is rotatably mounted on the end base, the end base is fixedly mounted on the internal tie rod, adjacent internal tie rods are fixedly connected by a connecting rod, and the connecting rod is fixedly mounted on the power tie rod, the relative position of the power tie rod and the hoisting rod is adjustable.

[0011] A further technical improvement of the present invention is that the lifting rod is clamped on the lifting base by a clamping mechanism, and the output end of the lifting equipment is installed on the lifting base.

[0012] A further technical improvement of the present invention is that: the clamping mechanism is fixedly installed at the output end of the telescopic rod, the telescopic rod is installed on the hoisting bracket through the mounting plate, the hoisting bracket is provided with a number of sets of mounting screw holes for bolting connection with the mounting plate, and the hoisting bracket and the hoisting base are fixedly connected.

[0013] A further technical improvement of the present invention is that: the clamping mechanism includes a clamping base fixedly installed on the telescopic rod, the clamping base is provided with a clamping moving groove for realizing the moving installation of the lifting rod, and the clamping base is provided with symmetrical clamping plates for lifting and limiting the lifting rod inside.

[0014] A further technical improvement of the present invention is that: a plate-shaped base is fixedly installed inside the clamping base, and symmetrical clamping plates are rotatably arranged on the plate-shaped base by clamping torsion springs, and the clamping surfaces of the symmetrical clamping plates are arc-shaped.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This application provides a lifting rod for hoisting the hammer body, and a number of limiting grooves are provided on the lifting rod. A retractable push plate is slidably installed in the limiting grooves, so that after the hammer body is evenly heated and placed, the lifting rod is removed from the hammer body. Then, by activating the retractable push plate, adjacent hammers can be isolated. Even when the lifting rod is moving, the retractable push plate can be used to separate the hammer bodies, avoiding the problem of collision between the hammer bodies.

[0016] 2. This application provides a lifting rod for hoisting the hammer body, and several limiting grooves are provided on the lifting rod. A retractable push plate is slidably installed in the limiting groove, so that when the hammer body is quenched, the presence of the retractable push plate can block the hammer body, allowing the hammer body to fully contact the coolant, ensuring the quality of its quenching, and thus further ensuring the precision of the hammer body.

[0017] 3. This application significantly improves the safety, efficiency and quality stability of hammerhead transfer during heat treatment through innovative mechanical linkage design and modular hoisting structure, while taking into account ease of operation and long-term maintenance costs, making it suitable for wear-resistant parts heat treatment scenarios in industrialized mass production.

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] Please see Figure 1-8 As shown, the wear-resistant hammer heat treatment system for a crusher includes a lifting base 20, on which a lifting bracket 21 is fixedly installed. The lifting base 20 is installed at the output end of the lifting equipment. By starting the lifting equipment, the position of the lifting base 20 can be moved, thereby moving the hammer body 1.

[0023] In the above technical solution, a plurality of mounting screw holes 22 are evenly provided on the hoisting bracket 21. Mounting plates 23 are detachably mounted on the mounting screw holes 22 by bolts, which are used to adjust the gap between adjacent mounting plates 23. A telescopic rod 24 is fixedly mounted on the mounting plate 23. A clamping mechanism 25 is installed at the output end of the telescopic rod 24. The clamping mechanism 25 is used to clamp and fix the hanger rod 2, thereby realizing the clamping limit of the hanger rod 2, and further realizing the position transfer of the hanger rod 2, so as to facilitate the transfer of the hammer body 1 set on the hanger rod 2.

[0024] Furthermore, a separation mechanism 3 is provided on the hanger rod 2. This separation mechanism 3 is used to separate adjacent hammer bodies 1, thereby creating a gap between adjacent hammer bodies 1. When transferring the hammer bodies 1, the separation mechanism 3 limits the movement of adjacent hammer bodies 1, preventing them from colliding and ensuring the stability of the hammer bodies 1.

[0025] As a further embodiment of this application, the separation mechanism 3 includes a limiting slide 4 and a retractable push plate 5. Several sets of limiting slide 4 are evenly opened on the hanger rod 2. The limiting slide 4 is circumferentially opened and the length of adjacent limiting slide 4 is the same. The retractable push plate 5 is slidably arranged inside the limiting slide 4. In use, the retractable push plate 5 is first moved to the inside of the hanger rod 2 under the limiting action of the limiting slide 4. Then, when the hanger rod 2 realizes the function of suspending the hammer body 1, the movement of the retractable push plate 5 from the limiting slide 4 realizes the limiting function between adjacent hammer bodies 1, so that there is a certain distance between adjacent hammer bodies 1, which facilitates the transfer of the hammer body 1.

[0026] In order to enable the retractable push plate 5 to slide inside the limiting slide groove 4, the retractable push plate 5 is connected to a power rod 7 through a power component. This enables relative sliding between the power rod 7 and the hanger rod 2, thereby activating the power component and causing it to push the retractable push plate 5 to slide inside the limiting slide groove 4, thus controlling the distance between adjacent hammer bodies 1.

[0027] Furthermore, the power assembly includes a limiting sleeve 9, which is installed on the top of the hammer body 1 to allow the hanger rod 2 to pass through and for subsequent installation of the hammer body 1. A limiting sliding base 8 is arranged circumferentially inside the hanger rod 2, with an internal groove 15 formed on the limiting sliding base 8. A limiting push plate 11 is slidably disposed on the internal groove 15, and the limiting push plate 11 is connected to the retracting push plate 5 via a limiting plate. In this application, the inner diameter of the limiting sleeve 9 is the same as the diameter of the hanger rod 2, thereby avoiding a stepped obstruction between the limiting sleeve 9 and the hanger rod 2. Simultaneously, a hinge rod 12 is rotatably disposed on the limiting push plate 11. The hinge rod 12 is mounted on the end base 13, which is fixedly mounted on the internal tie rod 14. The internal tie rod 14 is fixedly mounted on the power tie rod 7 via the connecting rod 10. In use, the internal tie rod 14 is pulled by the power tie rod 7, which in turn pulls the connecting rod 10. During this process, the end base 13 slides, adjusting the position of one end of the hinge rod 12. This allows the other end of the hinge rod 12 to apply power to the limiting push plate 11, enabling the limiting push plate 11 to move within the internal slide groove 15. This further moves the position of the retractable push plate 5, ensuring the position adjustment between the hammer bodies 1.

[0028] In the above technical solution, to further ensure the stability of the retractable push plate 5, an internal fixed base 16 is fixedly installed inside the hanger rod 2 at the end away from the retractable push plate 5. An end sliding groove 17 is provided on the internal fixed base 16, and an end sliding base 19 is slidably disposed on the end sliding groove 17. The retractable push plate 5 is fixedly installed on the end sliding base 19 through a connecting rod 18. In use, when the retractable push plate 5 moves under the action of the limiting push plate 11, in order to ensure the stability of the movement of the retractable push plate 5, the other end of the retractable push plate 5 slides inside the end sliding groove 17. A push spring is fixed between the end sliding groove 17 and the internal fixed base 16. That is, when there is no external force, the connecting rod 18 always maintains an outward pushing force under the action of the push spring, so as to ensure the stability of the retractable push plate 5 when separating the hammer body 1 and avoid collision between adjacent hammer bodies 1.

[0029] Furthermore, the clamping mechanism 25 includes a clamping base 26, on which a clamping moving groove 30 is provided for the passage of the hanger rod 2. A plate-shaped base 28 is fixedly installed on the inner wall of the clamping moving groove 30. A symmetrical clamping plate 29 is rotatably arranged on the plate-shaped base 28 by a clamping torsion spring 27. In use, when it is necessary to support the hanger rod 2, the hanger rod 2 is positioned at the bottom of the symmetrical clamping plate 29. Then, the clamping base 26 is moved toward the hanger rod 2 by the action of the telescopic rod 24. At this time, the symmetrical clamping plate 29 begins to rotate until the hanger rod 2 enters the interior of the clamping moving groove 30. At this time, under the action of the clamping torsion spring 27 and the centrifugal force, the symmetrical clamping plate 29 returns to its original position. The hanger rod 2 then falls onto the symmetrical clamping plate 29, thus supporting the hanger rod 2. During this process, since the symmetrical clamping plate 29 is arc-shaped, it is convenient to support the columnar hanger rod 2.

[0030] In use, the present invention first stops heating the hammer body 1 from the heating chamber, then uses the hanger rod 2 to enter the top groove of the hammer body 1. Then, the power rod 7 is pulled, causing the power rod 7 and the hanger rod 2 to move relative to each other. At this time, the retractable push plate 5 is pushed, causing the retractable push plate 5 to move out of the limiting slide groove 4. The retractable push plate 5 is used to separate the hammer bodies 1 until there is a certain gap between the hammer bodies 1. During the transfer of the hanger rod 2, it can be ensured that the hammer bodies 1 will not collide. The stability of the hammer bodies 1 during transfer is guaranteed, the processing accuracy of the hammer bodies 1 is guaranteed, and each hammer body 1 can be quenched evenly during quenching. During the above process, when the power rod 7 and the hanger rod 2 slide relative to each other, the power rod 7 drives the internal rod 14 and the connecting rod 10. During this process, the end base 13 slides, adjusting the position of one end of the hinge rod 12, thereby applying power to the limiting push plate 11 at the other end of the hinge rod 12. This allows the limiting push plate 11 to move inside the internal sliding groove 15, further moving the position of the retractable push plate 5 to ensure the position adjustment between the hammer bodies 1. At the same time, when the retractable push plate 5 moves under the action of the limiting push plate 11, in order to ensure the stability of the movement of the retractable push plate 5, the other end of the retractable push plate 5 slides inside the end sliding groove 17. A push spring is fixed between the end sliding groove 17 and the internal fixed base 16. That is, without the action of external force, the connecting rod 18 always maintains an outward pushing force under the action of the push spring, which is used to ensure the stability of the retractable push plate 5 when separating the hammer bodies 1 and to avoid collisions between adjacent hammer bodies 1. When hoisting the hanger rod 2, the hanger rod 2 is initially located at the bottom of the symmetrical clamping plate 29. Then, the clamping base 26 is moved toward the hanger rod 2 by the action of the telescopic rod 24. At this time, the position of the telescopic rod 24 can be fixed by external equipment to prevent the telescopic rod 24 from moving, such as by manual support. At this time, the symmetrical clamping plate 29 begins to rotate until the hanger rod 2 enters the interior of the clamping moving groove 30. At this time, under the action of the clamping torsion spring 27 and the centrifugal force, the symmetrical clamping plate 29 returns to its original position. The hanger rod 2 then falls onto the symmetrical clamping plate 29, thus supporting the hanger rod 2. During this process, since the symmetrical clamping plate 29 is arc-shaped, it is convenient to support the columnar hanger rod 2. Then, the position of the hanger rod 2 is transferred. After the transfer of the hanger rod 2 is completed, that is, after the quenching of the hammer body 1 is completed, when removing the hanger rod 2 from the hammer body 1, first return the retractable push plate 5 to its original position. At this time, since the hammer body 1 has a certain hardness, the collision between hammer bodies 1 will not affect the quality of the hammer body 1. Therefore, place the bottom of the hammer body 1 in a fixed position, and then move the lifting base 20 along a certain direction. At this time, push the hammer body 1 to move laterally until the clamping mechanism 25 at the other end moves away from the hanger rod 2, that is, the hanger rod 2 moves to the side of the clamping moving groove 30, thereby removing one of the clamping mechanisms 25. Using the action of the telescopic rod 24, the clamping mechanism 25 moves away from the hanger rod 2. Then, the lifting base 20 moves along another direction until the lifting base 20 moves away from the other end of the hanger rod 2. At this time, the clamping mechanism 25 and the hanger rod 2 can be separated, and the quenched hammer body 1 can be reassembled, which is convenient for the next step of processing of the hammer body 1.
