Description

Technical Field

[0001] The present invention relates to the technical field of quenching equipment, and specifically refers to a quenching equipment for a hydraulic cylinder body after heat treatment. Background Art

[0002] A hydraulic cylinder body usually refers to a component used in a hydraulic system, which is responsible for converting hydraulic energy into mechanical motion energy. The hydraulic cylinder body is generally made of metal, such as steel or aluminum alloy, to withstand the acting force of high-pressure liquid. In order to increase the hardness and strength of the hydraulic cylinder body and improve its wear resistance and corrosion resistance, it is usually necessary to perform quenching treatment on the hydraulic cylinder body.

[0003] The existing quenching equipment for a hydraulic cylinder body after heat treatment usually consists of a box filled with quenching liquid. During use, the hydraulic cylinder body is hoisted into the box to perform quenching operation on the hydraulic cylinder body. However, when the existing quenching equipment is in use, after the hydraulic cylinder body contacts the quenching liquid, it will quickly heat the quenching liquid around the hydraulic cylinder body, resulting in an increase in the temperature of the quenching liquid, thereby reducing the cooling speed of the hydraulic cylinder body, causing recrystallization of the structure, and affecting the hardness and wear resistance of the hydraulic cylinder body. At the same time, when the existing quenching equipment quenches a small-sized hydraulic cylinder body, in order to improve the quenching efficiency, multiple hydraulic cylinder bodies are usually placed in a container at the same time. Due to the different structures and placement positions of the hydraulic cylinder bodies, it is easy to cause different cooling efficiencies of different hydraulic cylinder bodies, affecting the uniformity of the product quality of the hydraulic cylinder body.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Combined with the attached Figure 1 、attached Figure 2 、attached Figure 4 、attached Figure 5 、attached Figure 6 、attached Figure 7 and attached Figure 11As shown in the figure, a quenching and cooling device for a hydraulic cylinder body after heat treatment includes a quenching and cooling box 1. The upper end of the quenching and cooling box 1 is provided with an opening, and the quenching and cooling box 1 is filled with quenching liquid. A steam absorption unit 8 is provided on the quenching and cooling box 1. The steam absorption unit 8 absorbs the steam generated during the quenching and cooling process of the hydraulic cylinder body to prevent the steam from escaping from the quenching and cooling box 1 and polluting the environment. This is the current existing technology and will not be elaborated here. A moving support mechanism 14 for driving the movement of the hydraulic cylinder body is slidably provided in the quenching and cooling box 1. The moving support mechanism 14 includes a sliding unit 4, a placement unit 5, and a rotating unit 3. The rotating unit 3 drives the sliding unit 4 to move. The placement unit 5 is rotatably provided on the sliding unit 4. The placement unit 5 includes a mating ratchet 52 and a substrate 51. A limiting unit 6 for fixing the hydraulic cylinder body is fixedly connected to the upper end of the substrate 51. The mating ratchet 52 is fixedly connected to the lower end of the substrate 51. A rotating column 21 is provided in the quenching and cooling box 1. A rotating block 22 that mates with the mating ratchet 52 is rotatably provided on the rotating column 21. A support spring 27 is provided between the rotating block 22 and the quenching and cooling box 1.

[0037] The working principle of the moving support mechanism 14: The rotating unit 3 drives the sliding unit 4 to perform reciprocating sliding. The sliding unit 4 drives the connected placement unit 5 to move. The placement unit 5 drives the connected limiting unit 6 to move synchronously. The placement unit 5 and the limiting unit 6 cooperate to clamp and limit the hydraulic cylinder body or the container of the hydraulic cylinder body. While the placement unit 5 is moving, the mating ratchet 52 moves synchronously. When the placement unit 5 drives the mating ratchet 52 to move to cooperate with the moving block, the rotating block 22 pushes the mating ratchet 52, and the mating ratchet 52 rotates. The mating ratchet 52 drives the placement unit 5 to rotate, realizing the rotation of the placement unit 5 while performing reciprocating movement.

[0038] Combined with attached Figure 3 、attached Figure 4 、attached Figure 5 、attached Figure 6 、attached Figure 8 、attached Figure 9 and attached Figure 10As shown in the figure, the rotating unit 3 includes a supporting plate 33 and a power unit 7 for driving the supporting plate 33 to rotate. The power unit 7 includes a driving motor 71, a protective cover 72 and a sealing ring 73. The output end of the driving motor 71 is connected to the rotating unit 3. The protective cover 72 is connected to the quenching tank 1. A sealing ring 73 is provided at the connection between the protective cover 72 and the driving motor 71 to improve the sealing performance of the driving motor 71. A driving rod 31 is eccentrically arranged on the supporting plate 33. The sliding unit 4 includes a sliding plate 45 and a driving chute 42 located below the sliding plate 45. The driving rod 31 is inserted into the driving chute 42. The rotation of the supporting plate 33 drives the sliding plate 45 to move through the cooperation of the driving rod 31 and the driving chute 42. The guiding unit 2 includes guiding blocks 29 symmetrically arranged on the inner wall of the quenching tank 1. Guide chutes 28 are provided on both groups of the guiding blocks 29. Extension blocks 43 are provided at both ends of the driving chute 42. Positioning sliders 44 slidably connected to the guide chutes 28 are provided on the extension blocks 43. Support arms 32 are provided at the lower end of the supporting plate 33. The support arms 32 are symmetrically arranged. Support slide rails 12 slidably connected to the support arms 32 are provided in the quenching tank 1.

[0039] The working principle of the sliding of the sliding unit 4: The driving motor 71 rotates, driving the supporting plate 33 connected thereto to rotate. The support arms 32 slide synchronously along the support slide rails 12. While the supporting plate 33 rotates, it drives the eccentrically arranged driving rod 31 to rotate. Since the positioning slider 44 is slidably connected to the guide chute 28, under the action of the extension block 43 and the driving chute 42, the sliding plate 45 can only move along the direction of the guide chute 28. On this basis, the rotating driving rod 31 can drive the sliding plate 45 to move along the direction of the guide chute 28 through the cooperating driving chute 42. Since the driving rod 31 driven by the supporting plate 33 performs a circular motion, the sliding plate 45 performs a reciprocating motion.

[0040] Combined with attached Figure 4 、attached Figure 5 、attached Figure 6 、attached Figure 7 、attached Figure 9 、attached Figure 10 and attached Figure 11 As shown in the figures, the rotating column 21 is arranged on the guiding block 29. A positioning plate 26 is provided on the guiding block 29. A supporting spring 27 connected to the rotating clamping block 22 is provided on the positioning plate 26. A positioning column 23 is provided on the guiding block 29. A positioning block 24 is provided on the positioning column 23. A positioning groove 25 cooperating with the positioning block 24 is provided on the rotating clamping block 22. A rotating rod 53 is provided at the lower end of the substrate 51. A connecting block 41 rotatably cooperating with the rotating rod 53 is provided on the sliding unit 4.

[0041] The working principle of the rotation of the placing unit 5: During the reciprocating movement of the placing unit 5 along with the sliding unit 4, when the mating ratchet wheel 52 contacts the rotating block 22, due to the support of the support spring 27 for the rotating block 22 and the limitation of the positioning block 24 and the positioning groove 25 for the rotating block 22, the rotating block 22 is enabled to push the mating ratchet wheel 52 to rotate. The rotating rod 53 rotates synchronously around the connecting block 41, and the substrate 51 rotates, thereby realizing the rotation of the placing unit 5.

[0042] Combined with the attached Figure 4 、attached Figure 5 、attached Figure 11 、attached Figure 12 、attached Figure 13 、attached Figure 14 and attached Figure 15 As shown in the attached drawings, the limiting unit 6 includes a bearing column 64 arranged on the substrate 51. A plurality of groups of bearing columns 64 are arranged at equal intervals along the circumferential direction of the substrate 51. A limiting plate 61 is arranged on the bearing column 64. A limiting sliding groove 62 is arranged on the limiting plate 61. A plurality of groups of limiting sliding grooves 62 are arranged at equal intervals along the circumferential direction of the limiting plate 61. A limiting sliding block 63 is slidably arranged on the limiting sliding groove 62. A mating unit 69 for guiding the hydraulic cylinder body is arranged at the upper end of the limiting sliding block 63. A synchronizing unit for driving a plurality of groups of the limiting sliding blocks 63 to slide synchronously is arranged at the lower end of the limiting sliding block 63;

[0043] The synchronizing unit includes a driving plate 67 rotatably arranged at the lower end of the limiting plate 61. A transmission rod 68 is arranged on the driving plate 67. An L-shaped support arm 66 is rotatably arranged on the transmission rod 68. A fixing rod 65 rotatably connected to the L-shaped support arm 66 is arranged on the limiting sliding block 63. A driving unit 15 for driving the driving plate 67 to rotate is arranged on the substrate 51. The driving unit 15 includes a rotating motor 151 arranged on the substrate 51. The output end of the rotating motor 151 is connected to the driving plate 67. A sealing cover 152 cooperating with the rotating motor 151 is arranged on the substrate 51. A sealing strip 153 is arranged at the connection between the sealing cover 152 and the rotating motor 151;

[0044] The mating unit 69 includes a mating block 691 arranged at the upper end of the limiting sliding block 63. A mating sliding groove 692 is arranged in the mating block 691. A mating sliding block 693 is slidably arranged on the mating sliding groove 692. A mating spring 694 connected to the mating sliding block 693 is arranged in the mating block 691. A mating plate 695 is arranged on the mating sliding block 693. A limiting baffle 696 is arranged at one end of the mating plate 695. A guiding plate 697 is rotatably arranged at the upper end of the limiting baffle 696. A guiding roller 698 is rotatably arranged on the guiding plate 697.

A guiding spring 6910 is sleeved on the guiding telescopic rod 699.

[0045] Working principle of the limiting unit 6: First, start the rotating motor 151. The rotating motor 151 drives the driving plate 67 to rotate. The driving plate 67 drives the L-shaped arm 66 to rotate through the transmission rod 68. The L-shaped arm 66 drives the limiting slider 63 to slide along the limiting chute 62 through the fixed rod 65. The sliding limiting slider 63 drives the mating block 691 to move away from the hydraulic cylinder body or the container for holding the hydraulic cylinder body, so that the mating block 691 is located outside the hydraulic cylinder body or the container for holding the hydraulic cylinder body;

[0046] Second, when the hydraulic cylinder body or the container for holding the hydraulic cylinder body falls to contact the guide plate 697, the guide rollers 698 on the guide plate 697 contact the outer wall of the hydraulic cylinder body or the container for holding the hydraulic cylinder body. The guide plate 697 squeezes the guide telescopic rod 699 and the guide spring 6910. The guide spring 6910 contracts and reacts on the guide plate 697 and the guide rollers 698 through deformation, so as to guide the hydraulic cylinder body or the container for holding the hydraulic cylinder body and make it fall to the middle position of the placing unit 5;

[0047] Third, start the rotating motor 151 in the reverse direction to make the output end of the rotating motor 151 rotate in the reverse direction and drive the driving plate 67 to rotate. The driving plate 67 drives the L-shaped arm 66 to rotate through the transmission rod 68. The L-shaped arm 66 drives the limiting slider 63 to slide along the limiting chute 62 through the fixed rod 65. The sliding limiting slider 63 drives the mating block 691 to move closer to the hydraulic cylinder body or the container for holding the hydraulic cylinder body. The mating slider 693 drives the limiting baffle 696 to move synchronously to abut against the outer wall of the hydraulic cylinder body or the container for holding the hydraulic cylinder body through the mating plate 695. The mating slider 693 squeezes the mating spring 694. The mating spring 694 contracts under force and reacts on the mating slider 693 in the reverse direction, so as to realize the clamping and fixing of the hydraulic cylinder body or the container for holding the hydraulic cylinder body.

[0048] Combined with Att Figure 1 、Att Figure 2 and Att Figure 3 As shown, a liquid storage tank 11 is communicated and provided at the lower end of the quenching tank 1. The liquid storage tank 11 is filled with quenching liquid. The liquid storage tank 11 is arranged below the ground. A cooling unit 9 is communicated and provided on one side of the quenching tank 1. A liquid inlet unit 10 is communicated and provided on the other side of the quenching tank 1. Both the cooling unit 9 and the liquid inlet unit 10 are communicated with the liquid storage tank 11. A partition is provided on the liquid storage tank 11, and a grille is provided on the partition, which protects the cooling unit 9 and the liquid inlet unit 10 while facilitating the heat exchange of the cooling unit 9 and improving the cooling effect of the cooling unit 9 on the quenching liquid;

[0049] The cooling unit 9 includes a liquid return pipe 901 disposed inside the quenching tank 1. Multiple groups of liquid return pipes 901 are arranged along the linear direction of the quenching tank 1. A manifold 902 communicating with the liquid return pipe 901 is provided outside the quenching tank 1. A cooling coil 903 is provided on the liquid storage tank 11, and the cooling coil 903 extends into the liquid storage tank 11. A liquid return pump 904 is provided on the quenching tank 1. The output end of the liquid return pump 904 communicates with the cooling coil 903, and the input end of the liquid return pump 904 communicates with the manifold 902. A cooling fan 905 is provided on the liquid storage tank 11, and the cooling fan 905 is correspondingly arranged with the cooling coil 903;

[0050] The liquid inlet unit 10 includes a liquid replenishing pipe 101 disposed inside the quenching tank 1. Multiple groups of liquid replenishing pipes 101 are arranged along the linear direction of the quenching tank 1. A distribution pipe 102 communicating with the liquid replenishing pipe 101 is provided outside the quenching tank 1. A liquid inlet pump 103 communicating with the distribution pipe 102 is provided on the quenching tank 1. A liquid inlet pipe 104 is provided on the liquid storage tank 11, and the liquid inlet pipe 104 extends into the liquid storage tank 11. The output end of the liquid inlet pump 103 communicates with the distribution pipe 102, and the input end of the liquid inlet pump 103 communicates with the liquid inlet pipe 104. An observation window 13 is provided on the quenching tank 1. The observation window 13 is of a transparent structure, and a scale 131 is provided on the observation window 13.

[0051] Advantages of the cooperation of the liquid storage tank 11, the cooling unit 9 and the liquid inlet unit 10: The liquid storage tank 11 is arranged below the ground. Through the heat preservation ability of the ground, the quenching liquid is kept at a low temperature, reducing the energy consumption for cooling the quenching liquid; The cooling unit 9 cooperates with the cooling coil 903 and the cooling fan 905 to efficiently cool the quenching liquid, improve the cooling effect of the hydraulic cylinder block, and improve the quenching efficiency; The transparent structure of the observation window 13 cooperates with the scale 131 to facilitate the operator to observe the stock of the quenching liquid and facilitate the timely replenishment of the quenching liquid.

[0052] Working principle of the cooperation between the cooling unit 9 and the liquid inlet unit 10: When the liquid return pump 904 and the liquid inlet pump 103 are in operation, the hot quenching liquid in the quenching tank 1 is collected into the manifold 902 through the liquid return pipe 901. The liquid return pump 904 pressurizes and pumps the hot quenching liquid in the manifold 902 into the cooling coil 903. The cooling fan 905 blows the ambient cold air towards the cooling coil 903. The cooling coil 903 exchanges heat with the ambient cold air, causing the quenching liquid in the cooling coil 903 to cool down. The cooled quenching liquid flows into the liquid storage tank 11. The low-temperature quenching liquid in the liquid storage tank 11 is pressurized and pumped through the liquid inlet pipe 104 by the liquid inlet pump 103 into the distribution pipe 102. The distribution pipe 102 conveys the low-temperature quenching liquid to the liquid replenishing pipe 101 and into the quenching tank 1, realizing the cooling and circulating flow of the quenching liquid in a cycle.

[0053] In the specific implementation of the present invention, during installation, the liquid storage tank 11 is placed underground so that the partition of the liquid storage tank 11 is on the same horizontal plane as the ground. Quenching liquid is replenished into the quenching tank 1 through the opening of the quenching tank 1. The return liquid pump 904 is started, and the return liquid pump 904 sucks the quenching liquid in the quenching tank 1 into the liquid storage tank 11 for storage. By cooperating the observation window 13 with the scale 131, the stock of the quenching liquid in the quenching tank 1 is observed. When the stock is appropriate, adding the quenching liquid is stopped, and the installation of the present invention is completed;

[0054] During daily use, first, the steam absorption unit 8 is started, and the return liquid pump 904, the liquid inlet pump 103, and the cooling fan 905 are started.

[0055] Second, the hydraulic cylinder body or the container containing the hydraulic cylinder body is hoisted into the quenching tank 1 and placed on the placing unit 5. The rotation motor 151 is started, and the hydraulic cylinder body or the container is clamped and fixed through the limiting unit 6;

[0056] Third, the driving motor 71 is started. The driving motor 71 drives the rotating unit 3 to rotate. The rotating unit 3 drives the connected sliding unit 4 to perform a reciprocating linear motion along the guiding unit 2, and the placing unit 5 moves synchronously. At this time, the quenched hydraulic cylinder body moves into the quenching liquid in the low-temperature part, realizing efficient cooling of the hydraulic cylinder body. During the movement of the placing unit 5, the ratchet 52 is cooperated with the rotating block 22. The rotating block 22 pushes the cooperating ratchet 52 to rotate. The cooperating ratchet 52 drives the placing unit 5 to rotate. The placing unit 5 drives the hydraulic cylinder body to rotate, so that the hydraulic cylinder bodies at different positions can obtain a uniform cooling speed, improving the uniformity of quenching and the uniformity of the quality of the hydraulic cylinder body;

[0057] During this process, the hot quenching liquid is cooled when passing through the cooling fan 905, and the cooled quenching liquid flows into the liquid storage tank 11.

[0058] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
