Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipe joint quenching technology, specifically a hydraulic pipe joint quenching device. Background Technology

[0002] The hydraulic system pipe assembly includes hydraulic system pipes, pipe fittings, sleeves, etc. In the processing of the hydraulic system pipe assembly, in order to improve the quality and performance of the pipe fittings, the pipe fittings are often hardened.

[0003] For example, the patent application number 2023231964327 discloses a surface heat treatment device for hydraulic pipe fitting processing, which solves the problem that most existing surface heat treatment devices for hydraulic pipe fitting processing are large-scale equipment and cannot perform heat treatment on small parts such as hydraulic pipe fittings and joints. However, it has the problems of not being able to perform heat treatment and quenching treatment on hydraulic pipe joints at the same time, low uniformity of heat treatment on hydraulic pipe joints, and poor quenching quality.

[0004] Based on this, the applicant proposes a hydraulic pipe joint quenching device. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing hydraulic pipe joint quenching devices, such as the inability to simultaneously perform heat treatment and quenching on hydraulic pipe joints, low uniformity of heat treatment, and poor quenching quality. The invention provides a hydraulic pipe joint quenching device with a reasonable structural design, capable of simultaneously performing heat treatment and quenching on hydraulic pipe joints, exhibiting good uniformity of heat treatment and high quenching quality.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] A quenching device for hydraulic pipe fittings includes a quenching box, a bearing shaft, material boxes, and a heating box. The quenching box has a vertical plate at its top, a fixing ring on the vertical plate, and a top plate with a pushing structure at the top. Quenching fluid is poured into the quenching box to quench the heat-treated hydraulic pipe fittings in the material box. The bearing shaft extends from both ends through the fixing ring. The material boxes are movably mounted on the bearing shaft and have drainage holes on their side walls and bottom. The bearing shaft drives multiple material boxes to rotate, which in turn causes the hydraulic pipe fittings in the material boxes to rotate, facilitating heat treatment of the hydraulic pipe fittings in the uppermost material box and the hydraulic pipe fittings in the lowermost material box. The joint undergoes quenching treatment. The heating box is connected to the pushing structure, which pushes the heating box down to cover the uppermost material box. The heat from the heating box enters the hydraulic pipe joint inside the material box, heat-treating the hydraulic pipe joint. After the hydraulic pipe joint is heated, the heating box rises under the action of the pushing structure, separating the heating box from the uppermost material box. The material box drives the heat-treated hydraulic pipe joint to rotate with the bearing shaft, allowing the heat-treated hydraulic pipe joint to enter the quenching liquid in the quenching box for quenching treatment. This allows the hydraulic pipe joint to undergo heat treatment and quenching treatment simultaneously, thereby improving the quenching efficiency and quenching quality of the hydraulic pipe joint.

[0008] Preferably, the bearing shaft is provided with a bearing rod, and a positioning ring is provided on the bearing rod. A connecting rod is provided on the outer wall of the top of the material box, and the connecting rod passes through the positioning ring. Multiple sets of bearing rods are provided on the bearing shaft, so that multiple material boxes can be placed on the bearing shaft. The bearing shaft drives the multiple material boxes to rotate, which in turn drives the hydraulic pipe joints to rotate. This facilitates the heat treatment of the hydraulic pipe joints in the uppermost material box and the quenching treatment of the hydraulic pipe joints in the lowermost material box, thereby improving the quenching efficiency and quenching quality of the hydraulic pipe joints.

[0009] Preferably, the bearing shaft is provided with handles at both ends, which make it easy for the operator to rotate the bearing shaft, thereby causing the bearing shaft to drive the material box and the hydraulic pipe joints inside the material box to rotate, and to perform heat treatment and quenching treatment on the hydraulic pipe joints inside the material box in sequence, thereby improving the quenching efficiency and quenching quality of the hydraulic pipe joints, and enhancing the quality performance of the hydraulic pipe joints after quenching.

[0010] Preferably, the pushing structure includes a hydraulic cylinder, which is mounted on the top plate. A piston rod is mounted on the hydraulic cylinder and connected to the heating box. The hydraulic cylinder and piston rod push the heating box down, covering the uppermost material box. Heat from the heating box enters the material box to heat-treat the hydraulic pipe joint. After the hydraulic pipe joint is heated, the heating box rises under the action of the pushing structure, separating the heating box from the uppermost material box, facilitating the quenching treatment of the heat-treated hydraulic pipe joint.

[0011] Preferably, the inner wall of the heating box is provided with heating blocks, and heating rods are provided between the heating blocks. A toggle structure is provided on the heating box. The heating blocks can generate heat from the heating rods. A large amount of heat in the heating box enters the uppermost material box through the leakage hole to heat treat the hydraulic pipe joints in the material box. This facilitates the quenching treatment of the heat-treated hydraulic pipe joints and can improve the quenching efficiency of the hydraulic pipe joints.

[0012] Preferably, the heating box is equipped with an air inlet pipe at the top, and a fan is installed inside the air inlet pipe. A hydraulic cylinder and a piston rod push the heating box down, so that the heating box covers the uppermost material box. The heat inside the heating box enters the material box to heat-treat the hydraulic pipe joints. The fan blows air into the heating box, and the airflow carrying heat fully enters the material box to fully heat-treat the hydraulic pipe joints inside the material box, thereby improving the heat treatment effect of the hydraulic pipe joints and enhancing the quality performance of the hydraulic pipe joints.

[0013] Preferably, the actuating structure includes a second hydraulic cylinder and a push plate. The second hydraulic cylinder is mounted on the outer wall of the heating chamber, and a second piston rod is mounted on the second hydraulic cylinder, extending into the heating chamber. The push plate is connected to the second piston rod, and a lever is mounted at the bottom of the push plate. When heat-treating the hydraulic pipe joints in the material box, the second hydraulic cylinder and the second piston rod push the push plate back and forth. The lever on the push plate actuates the hydraulic pipe joints in the material box, allowing the hydraulic pipe joints to fully contact the heat, thus performing thorough and uniform heat treatment on the hydraulic pipe joints and improving the uniformity of the heat treatment.

[0014] Preferably, the push plate is provided with a heat-conducting groove on its top, which contacts the heating rod. The push plate and push rod are made of metal. The push plate moves back and forth under the action of the second hydraulic cylinder and the second piston rod. The heat-conducting groove contacts the heating rod, and the heat on the heating rod is transferred to the push plate and then to the lever. When the lever moves the hydraulic pipe joint, the heat on the lever is transferred to the hydraulic pipe joint, which performs a thorough heat treatment on the hydraulic pipe joint, enhancing the heat treatment effect. By rotating the bearing shaft with the handle, the material box and the heated hydraulic pipe joint inside the material box are lowered, allowing the heat-treated hydraulic pipe joint to enter the quenching liquid and contact with the quenching liquid for quenching treatment, thereby enhancing the quenching efficiency and quenching quality of the hydraulic pipe joint.

[0015] Beneficial effects:

[0016] 1. Multiple sets of bearing rods are provided on the bearing shaft, so that multiple material boxes can be placed on the bearing shaft. The bearing shaft drives the multiple material boxes to rotate, which in turn drives the hydraulic pipe joints to rotate. This facilitates heat treatment of the hydraulic pipe joints in the uppermost material box and quenching treatment of the hydraulic pipe joints in the lowermost material box, thereby improving the quenching efficiency and quenching quality of the hydraulic pipe joints.

[0017] 2. Hydraulic cylinder 1 and piston rod 1 push the heating box down, so that the heating box covers the uppermost material box. The heat in the heating box enters the material box to heat treat the hydraulic pipe joint. After the hydraulic pipe joint is heated, the heating box rises under the action of the pushing structure, so that the heating box separates from the uppermost material box, making it convenient to quench the heated hydraulic pipe joint.

[0018] 3. The push plate moves back and forth under the action of hydraulic cylinder two and piston rod two. The heat conduction groove comes into contact with the heating rod. The heat on the heating rod is transferred to the push plate and then to the lever. When the lever moves the hydraulic pipe joint, the heat on the lever is transferred to the hydraulic pipe joint, which performs sufficient heat treatment on the hydraulic pipe joint and enhances the heat treatment effect of the hydraulic pipe joint.

[0027] The present invention will now be described in more detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] As attached Figure 1-5 As shown, a hydraulic pipe joint quenching device includes a quenching box 1, a bearing shaft 2, a material box 3, and a heating box 4. The top of the quenching box 1 is provided with a vertical plate 5, a fixing ring 6 is provided on the vertical plate 5, a top plate 7 is provided on the top of the vertical plate 5, and a pushing structure is provided on the top plate 7. The two ends of the bearing shaft 2 pass through the fixing ring 6. The material box 3 is movably mounted on the bearing shaft 2, and the side wall and bottom of the material box 3 are provided with leakage holes 14. The heating box 4 is connected to the pushing structure.

[0030] The bearing shaft 2 is provided with a bearing rod 11, and a positioning ring 12 is provided on the bearing rod 11. A connecting rod 13 is provided on the top outer wall of the material box 3, and the connecting rod 13 passes through the positioning ring 12. Handles 10 are provided at both ends of the bearing shaft 2.

[0031] The pushing structure includes a hydraulic cylinder 8, which is mounted on the top plate 7. A piston rod 9 is mounted on the hydraulic cylinder 8 and is connected to the heating box 4.

[0032] The heating box 4 has heating blocks 15 on its inner wall, heating rods 16 between the heating blocks 15, a toggle mechanism on the heating box 4, an air inlet pipe 17 on the top of the heating box 4, and a fan 18 inside the air inlet pipe 17.

[0033] The actuating structure includes a second hydraulic cylinder 19 and a push plate 20. The second hydraulic cylinder 19 is installed on the outer wall of the heating box 4. A second piston rod 21 is installed on the second hydraulic cylinder 19 and extends into the heating box 4. The push plate 20 is connected to the second piston rod 21. A lever 22 is installed at the bottom of the push plate 20. A heat conduction groove 23 is installed at the top of the push plate 20 and contacts the heating rod 16.

[0034] Example 2:

[0035] Further explanation is provided based on Example 1, as shown in the appendix. Figure 6-7 As shown, a hydraulic pipe fitting quenching device has a limiting groove 24 on the vertical plate 5 and a limiting rod 25 on the outer wall of the material box 3. The limiting rod 25 is inserted into the limiting groove 24. The material box 3 moves vertically under the action of the hydraulic cylinder 8 and the piston rod 9. The limiting rod 25 rises or falls within the limiting groove 24, so that the limiting rod 25 plays a limiting role on the heating box 4 during the vertical movement, thereby improving the stability of the heating box 4 during the vertical movement. This facilitates the heating box 4 to heat and quench the material box 3 and the hydraulic pipe fittings inside the material box 3, thereby improving the quenching efficiency and quenching quality of the hydraulic pipe fittings.

[0036] Working principle: Quenching fluid is poured into the quenching box 1 to quench the heat-treated hydraulic pipe fittings in the material box 3. The hydraulic pipe fittings to be quenched are placed into the material box 3. The operator can rotate the bearing shaft 2 via the handle 10, which in turn drives the material box 3 and the hydraulic pipe fittings inside to rotate. After one material box 3 is rotated to the top, the rotation of the bearing shaft 2 is stopped. Hydraulic cylinder 8 is activated, and hydraulic cylinder 8 and piston rod 9 push the heating box 4 down, so that the heating box 4 covers the top material box 3, and the heating is started. Block 15 and fan 18: Heating block 15 generates heat from heating rod 16. A large amount of heat from the heating box 4 enters the uppermost material box 3 through the leakage hole 14. Fan 18 blows airflow into the heating box 4, carrying heat into the material box 3, providing thorough and uniform heating to the hydraulic pipe joints within. Hydraulic cylinder 19 is activated, and its piston rod 21 pushes push plate 20 back and forth. The lever 22 on push plate 20 actuates the hydraulic pipe joints in the material box 3, allowing them to come into contact with the heat... With sufficient contact, the push plate 20 moves back and forth under the action of the second hydraulic cylinder 19 and the second piston rod 21. The heat conduction groove 23 contacts the heating rod 16, and the heat on the heating rod 16 is transferred to the push plate 20 and then to the lever 22. When the lever 22 moves the hydraulic pipe joint, the heat on the lever 22 is transferred to the hydraulic pipe joint, which undergoes sufficient heat treatment. After the heat treatment of the hydraulic pipe joint in the material box 3 is completed, the first hydraulic cylinder 8 is activated, and the heating box 4 rises under the action of the first hydraulic cylinder 8, separating the heating box 4 from the material box 3. The handle 10 allows the operator to rotate the bearing shaft 2, which in turn drives the material box 3 and the hydraulic pipe joints inside the material box 3 to rotate. This causes the hydraulic pipe joints inside the adjacent material box 3 to move to the highest position for heat treatment. After heat treatment, the hydraulic pipe joints enter the quenching liquid in the quenching box 1. The quenching liquid enters the material box 3 through the drain hole 14 to quench the heat-treated hydraulic pipe joints. After the hydraulic pipe joints are quenched, the bearing shaft 2 is rotated to continue to perform heat treatment and quenching on the hydraulic pipe joints in other material boxes 3.
