Description

Technical Field

[0001] This invention relates to the field of cylinder liner manufacturing technology, specifically to a tempering furnace for cylinder liner manufacturing. Background Technology

[0002] Tempering furnaces are used for tempering general metal machine parts in air, as well as for quenching, annealing, and aging heat treatment of light alloy machine parts such as aluminum alloy die castings, pistons, and aluminum plates. The outer shell is welded from steel plates and shaped steel, and the trolley is welded from shaped steel and steel plates. The trolley reduces heat radiation and convection losses through soft contact with the furnace lining and a sand sealing mechanism. Cylinder liners require tempering during processing. Tempering is used to reduce the brittleness of metal parts. The process involves holding the quenched metal parts at a suitable temperature for a long time before cooling them. This process relieves stress on the metal.

[0003] In existing tempering furnaces, the cylinder liner is often placed directly on a moving slide during tempering, which is not very stable. During the process of entering or exiting the furnace, the cylinder liner is prone to rolling off the moving slide, which can easily cause damage to the cylinder liner. At the same time, residue is easily left on the surface of the cylinder liner after tempering, which is quite troublesome to clean. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] Through the cooperation of the support components and the stabilizing components, the support ring supports the cylinder liner body. Pressing the cylinder liner body causes the support ring to descend, which in turn causes the vertical slide rod to drive the push protrusion to descend and squeeze the rotating cylinder. This forces the Y-shaped slide to squeeze the second spring and move it away from the push protrusion, thereby causing the second spring to contact the inner wall of the cylinder liner body. This achieves the limitation of the cylinder liner body's interior and improves the stability of the cylinder liner body.

[0017] When the cylinder liner body needs to be removed, pull the moving plate. The moving plate moves the sliding plate out of the tooth groove on the vertical tooth plate. Under the elastic action of the return spring, the support ring frame moves upward. The vertical slide rod moves the pushing protrusion upward. Under the action of the second spring, the Y-shaped slide is disengaged from the abutment ball. The support ring frame can lift the cylinder liner body upward, thus facilitating the removal of the cylinder liner body and improving convenience.

[0018] By incorporating a drive assembly, the drive wheel drives the worm to rotate, and the worm meshes with the worm wheel. The rotation of the worm drives the worm wheel to rotate, which in turn drives the rotating column and the cylinder liner body on it to rotate, making the cylinder liner body more evenly heated during the tempering process.

[0019] With the cleaning components installed, when the moving support plate is removed from the furnace body, the pushing plate sprays gas from the gas outlet pipe. The gas passes through the diversion pipe, the guide pipe and the vertical pipe in succession, and finally sprays out from the gas outlet head, blowing off the residue on the surface of the cylinder liner body, thus making the cleaning of the residue on the surface of the cylinder liner body more convenient.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 14This invention provides a technical solution: a tempering furnace for cylinder liner production, comprising a fixed base plate 1 and a furnace body 2 mounted on the fixed base plate 1. A movable support plate 3 is slidably connected to the fixed base plate 1. Multiple rotating vertical columns 6 are rotatably arranged on the movable support plate 3. A cylinder liner body 10 is sleeved on the rotating vertical columns 6. A support component 7 for supporting the cylinder liner body 10 is provided on the rotating vertical columns 6. A stabilizing component 9 for limiting the rotation of the rotating vertical columns 6 is provided on the rotating vertical columns 6. A locking component 8 is provided on the support component 7. A cleaning component 5 for cleaning residues on the surface of the cylinder liner body 10 is provided on the movable support plate 3. A drive mechanism is provided on the movable support plate 3. The cylinder liner body 10 is driven by a drive assembly 4. A fixed frame 11 is fixedly connected to the furnace body 2. A baffle 12 is slidably connected to the fixed frame 11. A hydraulic telescopic rod 13 is fixedly installed on the fixed frame 11. A connecting protrusion 14 is fixedly connected to the output end of the hydraulic telescopic rod 13. The connecting protrusion 14 is fixedly connected to the baffle 12. Through the cooperation of the support assembly 7 and the stabilizing assembly 9, the support ring frame 76 supports the cylinder liner body 10. Pressing the cylinder liner body 10 causes the support ring frame 76 to descend, which causes the vertical slide rod 91 to drive the push protrusion 92 to descend and squeeze the rotating cylinder 93. This forces the Y-shaped slide 94 to squeeze the second spring 95 and move away from the push protrusion 92. The movement causes the second spring 95 to contact the inner wall of the cylinder liner body 10, thus limiting the internal position of the cylinder liner body 10 and improving its stability. When the cylinder liner body 10 needs to be removed, the moving plate 85 is pulled, causing the sliding plate 83 to move out of the tooth groove on the vertical tooth plate 81. Under the elastic action of the return spring 74, the support ring frame 76 moves upward, and the vertical slide rod 91 drives the pushing protrusion 92 to move upward. Under the action of the second spring 95, the Y-shaped slide 94 disengages from the abutment ball 96, and the support ring frame 76 can lift the cylinder liner body 10 upward, thus facilitating its removal and improving convenience. With the drive assembly 4, the drive wheel 42 drives the worm 44 to rotate. The worm 44 meshes with the worm wheel 45. The rotation of the worm 44 drives the worm wheel 45 to rotate, which in turn drives the rotating column 6 and the cylinder liner body 10 on it to rotate. This makes the cylinder liner body 10 more evenly heated during the tempering process. With the cleaning assembly 5, when the moving support plate 3 is moved out of the furnace body 2, the push plate 510 sprays gas from the gas outlet pipe 53. The gas passes through the diversion pipe 55, the gas guide pipe 56 and the vertical pipe 57, and finally sprays out from the gas outlet head 58, blowing off the residue on the surface of the cylinder liner body 10. This makes cleaning the residue on the surface of the cylinder liner body 10 more convenient.

[0037] A threaded rod 15 is rotatably connected to the fixed base plate 1. The threaded rod 15 is threadedly connected to the movable support plate 3. One end of the threaded rod 15 is connected to a first motor 16, which is fixedly mounted on the fixed base plate 1. The drive assembly 4 includes a worm gear 45 fixed on the rotating vertical column 6. A worm 44 is meshed on one side of the worm gear 45. The worm 44 is rotatably mounted on the movable support plate 3 via a mounting block. One end of the worm 44 is fixedly connected to a drive wheel 42, and a belt 43 is wound around the drive wheel 42. One end of the drive wheel 42 is fixedly connected to a second motor 41, which is fixedly connected to the upper end of the movable support plate 3. The drive wheel 42 drives the worm 44 to rotate. The worm 44 meshes with the worm gear 45. The rotation of the worm 44 drives the worm gear 45 to rotate, which in turn drives the rotating vertical column 6 and the cylinder liner body 10 on it to rotate, making the cylinder liner body 10 more evenly heated during the tempering process.

[0038] Support assembly 7 includes a first fixed ring frame 71 fixedly mounted on the rotating vertical column 6. Four movable blocks 72 are slidably connected to the first fixed ring frame 71. Connecting inclined plates 75 are hinged to the movable blocks 72. A support ring frame 76 is hinged to the end of the connecting inclined plate 75 away from the movable blocks 72. The support ring frame 76 is slidably connected inside the rotating vertical column 6. A return spring 74 is fixedly connected to the end of the movable blocks 72 away from the rotating vertical column 6. A vertical connecting plate 73 is fixedly connected to the end of the return spring 74 away from the movable blocks 72. The vertical connecting plate 73 is fixedly connected to the first fixed ring frame 71. The upper end of the ring frame 71 and the lower end of the cylinder liner body 10 abut against the upper end of the support ring frame 76. The cylinder liner body 10 is fitted onto the rotating vertical column 6. Pressing the cylinder liner body 10 causes the support ring frame 76 to move downward. The support ring frame 76 drives the moving block 72 to slide on the first fixed ring frame 71 through the connecting inclined plate 75 and squeeze the return spring 74. Under the action of the cylinder liner body 10's own weight, the return spring 74 can be slightly squeezed. Pressing the cylinder liner body 10 downward can cause the return spring 74 to undergo a large deformation.

[0039] The stabilizing component 9 includes a vertical slide bar 91 fixedly installed on the upper end of the support ring frame 76. The vertical slide bar 91 is slidably connected inside the rotating vertical column 6. A pushing protrusion 92 is fixedly connected to the upper end of the vertical slide bar 91. The pushing protrusion 92 has an inclined surface, and a rotating cylinder 93 is rolledly connected to the inclined surface. Y-shaped slides 94 are rotatably connected to both ends of the rotating cylinder 93. The Y-shaped slides 94 are slidably connected inside the rotating vertical column 6. A second spring 95 is sleeved on the Y-shaped slides 94. The end of the Y-shaped slides 94 away from the pushing protrusion 92 extends out of the rotating vertical column 6 and is fixedly connected to an abutment ball 96. The vertical slide bar 91 drives the pushing protrusion 92 to descend, and the pushing protrusion 92 presses the rotating cylinder 93, forcing the Y-shaped slides 94 to press the second spring 95 and move away from the pushing protrusion 92. This causes the second spring 95 to contact the inner wall of the cylinder liner body 10, thereby limiting the movement inside the cylinder liner body 10 and improving the stability of the cylinder liner body 10.

[0040] Locking assembly 8 includes a vertical toothed plate 81, an L-shaped plate 82, a sliding retaining plate 83, a first spring 84, and a moving plate 85. The vertical toothed plate 81 is fixedly installed at the lower end of the support ring frame 76, and the L-shaped plate 82 is fixedly installed on the first fixed ring frame 71. The vertical toothed plate 81 slides through the L-shaped plate 82, and the sliding retaining plate 83 is slidably connected inside the L-shaped plate 82. The vertical toothed plate 81 has multiple toothed grooves for the sliding retaining plate 83 to engage with, and the end of the sliding retaining plate 83 near the vertical toothed plate 81 has an inclined surface. One end of the support ring 76 away from the vertical toothed plate 81 is fixedly connected to the movable plate 85. One end of the first spring 84 is fixedly connected to the movable plate 85, and the other end of the first spring 84 is fixedly connected to the L-shaped plate 82. The support ring 76 drives the vertical toothed plate 81 to slide downward, pressing the inclined surface on the sliding plate 83, so that the sliding plate 83 drives the movable plate 85 away from the L-shaped plate 82. Under the action of the first spring 84, the sliding plate 83 is locked in the tooth groove on the vertical toothed plate 81, thereby stabilizing the support ring 76.

[0041] Cleaning component 5 includes a sliding rod 51, an inlet pipe 52, an outlet pipe 53, a support frame 54, a diverter pipe 55, a guide pipe 56, a vertical pipe 57, an outlet head 58, a gas collecting chamber 59, a pusher plate 510, and an outlet 511. The gas collecting chamber 59 is located inside the movable support plate 3. The pusher plate 510 is slidably connected to the gas collecting chamber 59. One end of the sliding rod 51 is fixedly connected to the pusher plate 510, and the other end of the sliding rod 51 extends out of the movable support plate 3 and is fixedly connected to the inner wall of the furnace body 2. The sliding rod 51 is slidably connected to the movable support plate 3. The inlet pipe 52 is connected to one end of the movable support plate 3 near the furnace body 2, and the outlet pipe 53 is connected to one end of the movable support plate 3 near the inlet pipe 52. A one-way inlet valve is provided on the inlet pipe 52, and a one-way outlet valve is provided on the outlet pipe 53. An air outlet 511 is provided at the end of plate 3 away from the air inlet pipe 52. The support frame 54 is fixedly connected to the upper end of the movable support plate 3 near the cylinder liner body 10. The diversion pipe 55 is fixedly connected to the support frame 54. The diversion pipe 55 is connected to the vertical pipe 57 through the air guide pipe 56. Multiple air outlets 58 are connected to the vertical pipe 57. The end of the air outlet pipe 53 away from the movable support plate 3 is connected to the diversion pipe 55. The movable support plate 3 is moved out of the furnace body 2, and the push plate 510 sprays gas out from the air outlet pipe 53. The gas passes through the diversion pipe 55, the air guide pipe 56 and the vertical pipe 57 in sequence, and is finally sprayed out from the air outlet 58, blowing off the residue on the surface of the cylinder liner body 10. At this time, the cylinder liner body 10 is still rotating, which facilitates cleaning around the cylinder liner body 10 and improves convenience.

[0042] In practical use, the cylinder liner body 10 is fitted onto the rotating vertical column 6. Pressing the cylinder liner body 10 causes the support ring frame 76 to move downwards. The support ring frame 76, through the connecting inclined plate 75, drives the moving block 72 to slide on the first fixed ring frame 71 and compress the return spring 74. During the descent of the support ring frame 76, the vertical slide rod 91 drives the pushing protrusion 92 to descend, which in turn compresses the rotating cylinder 93. This forces the Y-shaped slide 94 to compress the second spring 95 and move it away from the pushing protrusion 92. Consequently, the second spring 95 comes into contact with the inner wall of the cylinder liner body 10, thus limiting the movement of the cylinder liner body 10 and improving its stability. Stability is achieved during this process. The support ring frame 76 drives the vertical toothed plate 81 to slide downwards, pressing the inclined surface on the sliding plate 83. This causes the sliding plate 83 to move the moving plate 85 away from the L-shaped plate 82. Under the action of the first spring 84, the sliding plate 83 is locked in the tooth groove on the vertical toothed plate 81, thus stabilizing the support ring frame 76. After the cylinder liner body 10 is placed, the first motor 16 is started. The first motor 16 drives the threaded rod 15 to rotate. The threaded rod 15 drives the moving bearing plate 3 to move into the furnace body 2. During the movement of the moving bearing plate 3, the pushing plate 510 squeezes the gas in the gas collecting chamber 59 out of the gas outlet 511. A negative pressure is formed on the left side of the pushing plate 510, and the gas flows out from the inlet. Gas pipe 52 enters the left side of push plate 510 to prepare for subsequent cleaning. Drive wheel 42 drives worm 44 to rotate. Worm 44 meshes with worm wheel 45. The rotation of worm 44 drives worm wheel 45 to rotate, which in turn drives rotating column 6 and cylinder liner body 10 on it to rotate, making the cylinder liner body 10 more evenly heated during tempering. After tempering, the first motor 16 drives threaded rod 15 to reverse, moving moving support plate 3 out of furnace body 2. Push plate 510 sprays gas from gas outlet pipe 53. The gas passes through diverter pipe 55, gas guide pipe 56 and vertical pipe 57, and finally sprays out from gas outlet head 58, blowing off residue on the surface of cylinder liner body 10. At this time, the cylinder... The cylinder liner body 10 is still rotating, which facilitates cleaning around the cylinder liner body 10 and improves convenience. After the moving support plate 3 is moved out of the furnace body 2, the second motor 41 is turned off. After the cylinder liner body 10 has cooled down, when it is necessary to remove the cylinder liner body 10, the moving plate 85 is pulled. The moving plate 85 drives the sliding plate 83 to move out of the tooth groove on the vertical tooth plate 81. Under the elastic action of the return spring 74, the support ring frame 76 moves upward. The support ring frame 76 can lift the cylinder liner body 10 upward. The vertical slide rod 91 drives the pushing protrusion 92 to move upward. Under the action of the second spring 95, the Y-shaped slide 94 is disengaged from the abutting ball 96, which facilitates the removal of the cylinder liner body 10.
