Description

Technical Field

[0001] The utility model relates to the technical field of track link processing, and specifically relates to a heat treatment device for track link processing. Background Technique

[0002] The track link is an important component used for connection in the tracks of construction machinery such as excavators and bulldozers and military machinery such as tanks. During the processing of track links, in order to improve the internal stress of its structure and make its use effect better, heat treatment needs to be carried out on the track links. For example, a heat treatment device for track link production disclosed in CN114085961A includes a main body with a "convex" - shaped chute formed at the top and an electromagnetic coil installed at one end of the main body; a power unit having a driving motor and a bidirectional threaded rod, and the driving motor is installed on one side of the main body. In this technical solution, the position of the electromagnetic coil is fixed. After the first clamping plate and the second clamping plate move synchronously and in opposite directions to clamp the track link, the middle position of the track link is in the same plane as the middle position of the electromagnetic coil, and it is impossible to perform heat treatment on the two ends of a longer track link, which reduces the applicable range. Moreover, when loading and unloading the track link, the track link cannot be supported, and it may collide with the electromagnetic coil, bringing inconvenience to use. There are problems such as a small number of track links heat - treated at one time, low quality of track link heat treatment, and low uniformity of track link heat treatment.

[0003] Based on this, the applicant proposes a heat treatment device for track link production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat treatment device for track link processing with a reasonable structural design, a large number of track links heat - treated at one time, capable of fully heat - treating track links, and good quality of track link heat treatment, aiming at the problems of a small number of track links heat - treated at one time, low quality of track link heat treatment, and low uniformity of track link heat treatment existing in the existing track link heat treatment.

[0005] The technical solution adopted by the utility model to solve the technical problems is as follows:

[0006] A heat treatment device for processing track links includes a support frame and a heating chamber. A column is mounted on top of the support frame, and a top plate is mounted on the top plate. A pushing structure is mounted on the top plate, and a heat-conducting structure is mounted on the pushing structure. The support frame and the column are welded together, which enhances the connection strength between the support frame and the column, thereby improving the structural strength of the heat treatment device. A driving structure is provided between the supports. The heating chamber is movably disposed between the supports, and its bottom is movably connected to the driving structure. The driving structure can drive the heating chamber and the track links inside the heating chamber to move back and forth, allowing the track links to contact the heat-conducting structure. This facilitates the heat transfer of heat to the track links, heating the interior of the track links and improving the heat treatment effect.

[0007] Preferably, the drive structure on the bracket includes a drive motor and gears. The bracket is equipped with bearings, the drive motor is mounted on the bracket, and a transmission shaft is mounted on the drive motor, with one end of the transmission shaft inserted into the bearing. The gear is mounted on the transmission shaft and is movably connected to the bottom of the heating chamber. The drive motor drives the transmission shaft and the gear on the transmission shaft to rotate forward or backward. The gear pushes the heating chamber to move back and forth between the brackets, causing the track links inside the heating chamber to move back and forth. This ensures that the track links are in full contact with the heat inside the heating chamber, and that the track links are in contact with the heat-conducting structure while being heat-treated inside the heating chamber. This facilitates the heat-conducting structure to transfer heat to the track links, thus heating the inside of the track links and improving the heat treatment effect of the track links.

[0008] Preferably, the bottom of the heating box is provided with a rack and pinion, which meshes with a gear. The gear rotates under the action of the drive motor, pushing the rack and pinion to move, thereby causing the heating box to move back and forth between the supports. This facilitates the contact between the track links at different positions inside the heating box and the heat-conducting structure, allowing for sufficient heating of the track links and thus improving the heat treatment effect of the track links.

[0009] Preferably, the support sidewall is provided with a fixing groove, and the heating box outer wall is provided with a connecting rod. The connecting rod is inserted into the fixing groove, and an auxiliary wheel is provided on the connecting rod. The heating box moves back and forth under the action of the drive motor, and the auxiliary wheel on the connecting rod rolls in the fixing groove. This can reduce the resistance encountered by the heating box during the movement and improve the stability of the heating box driving the track link to move back and forth.

[0010] Preferably, a heating block is provided at the bottom of the heating chamber, and a support block is provided on the inner side wall of the heating chamber. A heating tube is provided between the heating blocks, and a support groove is provided on the support block. The track links to be heat-treated are suspended on the support rod, and both ends of the support rod are placed into the support groove on the support block to improve the stability of the support rod. The heating block provides electrical energy for the operation of the heating tube. During the operation of the heating tube, a large amount of heat is generated, so that the inside of the heating chamber is at a high temperature. The heat inside the heating chamber heat-treats the track links suspended on the support rod, so that the heat is transferred from the surface of the track links to the inside of the track links. Multiple track links can be suspended on the support rod, so that multiple track links can be heat-treated at the same time, increasing the number of track links that can be heat-treated at one time. In order to further improve the heat treatment effect of the track links, the support rod can be made of metal material. The heat absorbed by the support rod is transferred to the surface of the track links in contact with it, so as to fully heat-treat the track links and enhance the heat treatment effect of the track links.

[0011] Preferably, the pushing structure includes a hydraulic cylinder and a pushing frame. The hydraulic cylinder is mounted on the top plate and has a piston rod. The pushing frame is connected to the piston rod. The hydraulic cylinder and piston rod push the pushing frame downward, causing the pushing frame to move the heat-conducting structure vertically. This facilitates contact between the heat-conducting structure and the top of the chain link inside the heating box, allowing heat from the heat-conducting structure to be transferred to the chain link. This improves the heat treatment efficiency and quality of the chain link, and enhances the quality performance of the processed chain link.

[0012] Preferably, the heat-conducting structure includes a heating plate and a heat-conducting plate. The heating plate is located at the top inside the push frame, and a heat-conducting cylinder is provided on the heating plate, with its bottom end extending out of the push frame. The heat-conducting plate has an arc-shaped structure, and heat-conducting columns are provided on the heat-conducting plate, with the tops of the heat-conducting columns inserted into the heat-conducting cylinder. The heat generated by the heating plate during operation is transferred to the heat-conducting cylinder, and the heat on the heat-conducting cylinder is transferred to the heat-conducting plate through the heat-conducting columns. The heat-conducting plate moves vertically with the push frame under the action of a hydraulic cylinder, and the heat-conducting plate contacts the top of the track link suspended on the support rod, so that the heat on the heat-conducting plate is transferred to the top of the track link. This facilitates heat treatment of the inside of the track link, improves the heat treatment efficiency and quality of the track link, and enhances the quality performance of the processed track link. The arc-shaped structure of the heat-conducting plate facilitates the sliding of the track link moving with the heating box on the surface of the heat-conducting plate, making it convenient for the track link to move back and forth, thereby improving the heat treatment efficiency of the track link.

[0013] Preferably, the top of the heat-conducting column is connected to the top of the heat-conducting cylinder by a connecting spring. The connecting spring provides a buffer between the heat-conducting column and the heat-conducting cylinder, preventing the heat-conducting plate from pressing down on the chain link, which would cause the chain link to move back and forth with the heating box to become obstructed, thereby improving the heat treatment efficiency of the chain link.

[0014] Beneficial effects:

[0015] 1. The drive motor drives the transmission shaft and the gears on the transmission shaft to rotate in the forward or reverse direction. The gears push the heating box to move back and forth between the supports, which in turn drives the track links inside the heating box to move back and forth. This allows the track links to come into contact with the heat-conducting structure while being heat-treated inside the heating box, making it easier for the heat-conducting structure to transfer heat to the track links and heat the inside of the track links, thereby improving the heat treatment effect of the track links.

[0016] 2. The heating block provides electrical energy for the operation of the heating tube. During operation, the heating tube generates a large amount of heat, keeping the inside of the heating chamber at a high temperature. The heat inside the heating chamber heats the track links suspended on the support rod, allowing heat to be transferred from the surface of the track links to their interior. To further improve the heat treatment effect of the track links, the support rod can be made of metal. The heat absorbed by the support rod is transferred to the surface of the track links in contact with it, thus fully heat treating the track links and enhancing their heat treatment effect.

[0017] 3. The heat-conducting plate moves vertically with the push frame under the action of the hydraulic cylinder. The heat-conducting plate contacts the top of the track link hanging on the support rod, so that the heat on the heat-conducting plate is transferred to the top of the track link. This facilitates heat treatment inside the track link, improves the heat treatment efficiency and quality of the track link, and enhances the quality performance of the track link after processing. The heat-conducting plate is set with an arc-shaped structure, which facilitates the sliding of the track link moving with the heating box on the surface of the heat-conducting plate, making it convenient for the track link to move back and forth, thereby improving the heat treatment efficiency of the track link.

A heat-conducting cylinder 22 is provided on the heating plate 20, and the bottom end of the heat-conducting cylinder 22 extends out of the push frame 18. The heat-conducting plate 21 has an arc-shaped structure. A heat-conducting column 23 is provided on the heat-conducting plate 21, and the top end of the heat-conducting column 23 is inserted into the heat-conducting cylinder 22. The top end of the heat-conducting column 23 is connected to the top end of the heat-conducting cylinder 22 by a connecting spring 24.

[0034] Example 2:

[0035] This embodiment is a further description based on Embodiment 1, as shown in the appendix. Figure 7 As shown: A limiting plate 25 is provided on the outer wall of the push frame 18, and a limiting ring 26 is provided on the limiting plate 25. The column 4 passes vertically through the limiting ring 26. The push frame 18 moves vertically under the action of the hydraulic cylinder 17 and the piston rod 19. The limiting ring 26 moves vertically along the column 4, so that the limiting plate 25 and the limiting ring 26 can limit the rising or falling push frame 18, thereby improving the stability of the heat-conducting plate 21 during the adjustment process, facilitating the contact between the heat-conducting plate 21 and the chain link in the heating box 2, and heating the chain link to improve the heating efficiency and heating quality of the chain link.

[0036] Working principle: The track links requiring heat treatment are suspended on the support rod, with both ends of the support rod placed into the support grooves 15 on the support block 13, so that the track links are suspended in the heating chamber 2. The heating block 14 provides electrical energy for the heating tube 16. During operation, the heating tube 16 generates a large amount of heat, keeping the interior of the heating chamber 2 at a high temperature. The heat inside the heating chamber 2 heats the track links suspended on the support rod, transferring heat from the surface of the track links to their interior. The drive motor 7 is started, driving the transmission shaft 8 and the gear 9 on the transmission shaft 8 to rotate forward or backward. The gear 9 pushes the heating chamber 2 to move back and forth between the supports 1, causing the track links inside the heating chamber 2 to move back and forth, ensuring that the track links come into full contact with the heat and are fully heat-treated. The heating plate 20 is activated, and the heat generated during its operation is transferred to the heat-conducting cylinder 22. The heat on the heat-conducting cylinder 22 is transferred to the heat-conducting plate 21 through the heat-conducting column 23. The heat-conducting plate 21 moves vertically with the push frame 18 under the action of the hydraulic cylinder 17. The heat-conducting plate 21 contacts the top of the track link hanging on the support rod, so that the heat on the heat-conducting plate 21 is transferred to the top of the track link, which facilitates the heat treatment of the inside of the track link. The heat-conducting plate 21 is set as an arc structure, which facilitates the sliding of the track link moving with the heating box 2 on the surface of the heat-conducting plate 21, and facilitates the back-and-forth movement of the track link. After the heat treatment of the track link is completed, the support rod is lifted out of the heating box 2, and the heat-treated track link is removed from the heating box 2 with the support rod. A new track link that needs to be heat-treated is then replaced to continue the heat treatment.
