Description

Technical Field

[0001] This application relates to the field of steel plate processing technology, and in particular to a leaf spring heating machine. Background Technology

[0002] A leaf spring is a type of spring made of at least one stacked leaf of spring steel, typically used in the suspension systems of wheeled vehicles. The main characteristics of a leaf spring include its structure, which consists of multiple stacked spring steel leaves. This design gives it good load-bearing capacity and vibration damping effect. Therefore, during the production of leaf springs, they need to be heated and tempered to enhance their mechanical properties.

[0003] Currently, the process of heating and tempering leaf springs usually involves stacking multiple leaf springs together and then transporting them to a heating furnace using hoisting equipment. However, traditional heating furnaces are large in size and consume a lot of energy, making them suitable only for heating large batches of workpieces. For small batches of workpieces, the processing cost is high. Manually heat-treating each workpiece individually would increase the labor intensity of workers and result in low efficiency, which are both inconvenient. Utility Model Content

[0004] In order to improve the problems caused by heat treatment of small batches of leaf spring workpieces, this application provides a leaf spring heating machine.

[0005] The leaf spring heating machine provided in this application adopts the following technical solution:

[0006] A leaf spring heating machine includes a processing table, a heating box, and a feeding assembly. The heating box has an inlet and an outlet. A support rod is provided between the inlet and the outlet of the heating box. The feeding assembly includes feeding rails symmetrically arranged about the axis of the support rod. The feeding rails slide through the inlet and the outlet of the heating box. A plurality of push blocks are evenly arranged along the length of the feeding rails. The leaf springs are located between two adjacent push blocks, and the push blocks are used to clamp the leaf springs. The processing table is provided with a separating and joining assembly for driving the two feeding rails to separate or move closer to each other. The processing table is also provided with a driving assembly for driving the feeding rails to slide along the axis of the support rod.

[0007] By adopting the above technical solution, the worker places the leaf spring on the support rod, and then drives the conveyor rail to slide through the drive assembly. The sliding conveyor rail drives the pusher block to push the leaf spring along the feed port of the heating box to its discharge port a certain distance. The heating box then heats the leaf spring. The separation and engagement assembly controls the two conveyor rails to separate from each other, so that the pusher block moves away from the leaf spring. Then the drive assembly drives the conveyor rails to reset. After that, the separation and engagement assembly controls the two conveyor rails to move closer to each other, and the next leaf spring is picked up again. The operation is repeated until each leaf spring is heated, thereby performing heat treatment on a small batch of workpieces.

[0008] Optionally, the heating chamber is equipped with a heating coil electrically connected to the control system, the heating chamber is equipped with a mounting frame, the mounting frame is equipped with a temperature measuring instrument electrically connected to the control system, a temperature measuring port is opened between the inner and outer walls of the heating chamber, and the temperature measuring end of the temperature measuring instrument points to the temperature measuring port.

[0009] By adopting the above technical solution, when the leaf spring is moved to the temperature measuring port, the temperature measuring instrument will promptly feed back the tempering temperature of each leaf spring to the control system, thereby controlling the performance of each leaf spring to be more consistent.

[0010] Optionally, the splitting and joining assembly includes a first bidirectional screw and a second bidirectional screw rotatably mounted on the processing table. The first bidirectional screw and the second bidirectional screw are respectively located at both ends of the length direction of the feed rail. Both ends of the first bidirectional screw are threadedly connected to a first sliding plate, and both ends of the second bidirectional screw are threadedly connected to a second sliding plate. The first sliding plate and the second sliding plate are slidably engaged with the processing table. The first sliding plate and the second sliding plate are respectively located at both ends of the length direction of the feed rail. A rotating component is provided on the processing table, which is used to drive the first bidirectional screw and the second bidirectional screw to rotate synchronously.

[0011] By adopting the above technical solution, the rotating component drives the first bidirectional screw and the second bidirectional screw to rotate synchronously, so that the two first sliding plates on the first bidirectional screw move away from each other at the same time, and the two second sliding plates on the second bidirectional screw move away from each other at the same time. This controls the two material conveying rails to drive the push blocks on them to slide away from each other at the same time, thereby facilitating the reset of the material conveying rails and pushing the next leaf spring.

[0012] Optionally, the rotating component includes a splitting and engaging motor mounted on the machining table and electrically connected to the control system. A splitting and engaging shaft is coaxially mounted on the output shaft of the splitting and engaging motor. Gearboxes for transmitting torque are provided between the splitting and engaging shaft and the first bidirectional screw, and between the splitting and engaging shaft and the second bidirectional screw.

[0013] By adopting the above technical solution, the control system starts the splitting and connecting motor. The output shaft of the splitting and connecting motor drives the splitting and connecting shaft to rotate. The splitting and connecting shaft drives the first bidirectional screw and the second bidirectional screw to rotate synchronously through two gearboxes, thereby controlling the first and second sliding plates at the end of the material conveying rail to slide synchronously and in the same direction.

[0014] Optionally, the driving assembly includes a reciprocating slide rail arranged along the length of the feeding rail, a push plate sliding on the reciprocating slide rail, the feeding rail slidingly engaging with the first slide plate and the second slide plate and sliding along the length of the feeding rail, two connecting blocks slidingly arranged on the push plate along the axis of the first bidirectional screw, the connecting blocks being arranged on the feeding rail and corresponding one-to-one with the feeding rail, a push screw rotatably arranged on the processing table, the push plate being threadedly connected to the push screw, and a reciprocating component driving the push screw to rotate on the processing table.

[0015] By adopting the above technical solution, the reciprocating component drives the push screw to rotate. Under the restriction of the reciprocating slide rail, and because the sliding direction of the connecting block is perpendicular to the sliding direction of the push plate, the push plate drives the conveying rail to slide along the length direction of the conveying rail through the connecting block. This causes the conveying rail to drive the push block to push the leaf spring to slide along the direction from the feed port to the discharge port on the heating box.

[0016] Optionally, the reciprocating component includes a reciprocating motor mounted on the processing table and electrically connected to the control system. Both the output shaft of the reciprocating motor and the push screw are provided with synchronous pulleys, and a synchronous belt is wound between the synchronous pulley on the output shaft of the reciprocating motor and the synchronous pulley on the push screw.

[0017] By adopting the above technical solution, the control system starts the reciprocating motor. The output shaft of the reciprocating motor drives the push screw to rotate through the synchronous pulley and synchronous belt. The reciprocating slide of the push plate is achieved by the forward and reverse rotation of the reciprocating motor.

[0018] Optionally, the processing table is provided with a material picking base, a material picking plate is slidably arranged on the material picking base, a material picking cylinder electrically connected to the control system is provided on the material picking base, the material picking plate is arranged on the piston rod of the material picking cylinder, a material picking claw is rotatably arranged on the material picking plate, the material picking claw is used to rotate and lift the heated leaf spring, and a plate picking component is provided on the material picking plate to drive the material picking claw to rotate.

[0019] By adopting the above technical solution, when the heated leaf spring slides out of the outlet of the heating box, the control system starts the picking cylinder. The piston rod of the picking cylinder pushes the picking plate close to the leaf spring. At this time, the picking claw is located at the bottom of the leaf spring. Then the picking plate drives the picking claw to rotate, thereby lifting the leaf spring. At this time, the leaf spring is separated from the conveying rail, which facilitates the transfer of the heated leaf spring by subsequent equipment.

[0020] Optionally, the plate-retrieving component includes a rotating plate cylinder disposed on the plate and electrically connected to the control system. A drive rod is disposed on the piston rod of the rotating plate cylinder. A guide groove for sliding of the drive rod is provided on the plate along the axis of the piston rod of the rotating plate cylinder. An inclined slot for sliding of the drive rod is provided on the claw. The inclined slot is inclined towards the rotating plate cylinder in a downward direction.

[0021] By adopting the above technical solution, the control system starts the rotating plate cylinder. The piston rod of the rotating plate cylinder drives the drive rod to slide along the length of the guide groove. Since there is an angle between the inclined groove and the guide groove, when the drive rod slides, the relative sliding between the drive rod and the guide groove causes the picking claw to rotate around its rotation center, thereby achieving the effect of lifting the leaf spring with the picking claw.

[0022] Optionally, a pull-out frame is vertically slidably mounted on the processing table, the pull-out frame is located directly below the picking claw, and a lifting cylinder electrically connected to the control system is mounted on the processing table, with the pull-out frame mounted on the piston rod of the lifting cylinder.

[0023] By adopting the above technical solution, the control system starts the lifting cylinder, the piston rod of the lifting cylinder pushes the extraction frame to rise, the extraction frame lifts the leaf spring on the picking claw, then the picking cylinder controls the picking plate to reset, and then the extraction frame drives the leaf spring to fall, and the heated leaf spring cools naturally on the extraction frame, thereby realizing the sampling process of the heated leaf spring.

[0024] Optionally, a material-carrying cylinder electrically connected to the control system is provided on the processing table between the push plate and the heating box. A material-placing frame is provided on the piston rod of the material-carrying cylinder. The material-placing frame is located between the two material conveying rails, and a leaf spring is placed on the material-placing frame.

[0025] By adopting the above technical solution, the worker places the leaf spring on the material rack, and then the control system starts the loading cylinder. The piston rod of the loading cylinder drives the leaf spring on the material rack to descend, so as to facilitate the push block on the conveying rail to clamp and drive the leaf spring to move synchronously.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The worker places the leaf spring on the support rod, and then drives the feed rail to slide through the drive assembly. The sliding feed rail drives the push block to push the leaf spring along the feed port of the heating box to its discharge port. After a certain distance, the heating box heats the leaf spring. The separation and engagement assembly controls the two feed rails to separate from each other, so that the push block moves away from the leaf spring. Then the drive assembly drives the feed rail to reset. After that, the separation and engagement assembly controls the two feed rails to move closer to each other, and the next leaf spring is picked up again. The operation is repeated until each leaf spring is heated, so as to perform heat treatment on a small batch of workpieces.

[0028] 2. The control system starts the splitting and connecting motor. The output shaft of the splitting and connecting motor drives the splitting and connecting shaft to rotate. The splitting and connecting shaft drives the first bidirectional screw and the second bidirectional screw to rotate synchronously through two gearboxes, thereby controlling the first and second slide plates at the end of the material conveying rail to slide synchronously and in the same direction.

[0029] 3. After the heated leaf spring slides out of the outlet of the heating box, the control system starts the picking cylinder. The piston rod of the picking cylinder pushes the picking plate close to the leaf spring. At this time, the picking claw is located at the bottom of the leaf spring. Then the picking plate drives the picking claw to rotate, thereby lifting the leaf spring. At this time, the leaf spring is separated from the conveying rail, which facilitates the transfer of the heated leaf spring by subsequent equipment. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0036] This application discloses a leaf spring heating machine.

[0037] Reference Figure 1 A leaf spring heating machine includes a processing table 1, a heating box 2, and a material conveying assembly 3. A heating coil 9, which is electrically connected to a control system, is bolted inside the heating box 2. A mounting frame 10 is welded to the top of the heating box 2, and a temperature measuring instrument 11, which is electrically connected to the control system, is bolted to the mounting frame 10. A temperature measuring port 12 is opened between the inner and outer walls of the top of the heating box 2, and the temperature measuring end of the temperature measuring instrument 11 points to the temperature measuring port 12.

[0038] Reference Figure 1 and Figure 2 The heating box 2 has an inlet 4 and an outlet 5. A support rod 6 is welded between the inlet 4 and the outlet 5 of the heating box 2. Multiple support ceramics 22 are bolted to the support rod 6 along its axis. The support ceramics 22 slide with the leaf spring 0.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The feeding assembly 3 includes two feeding rails 31 arranged symmetrically about the axis of the support rod 6. The feeding rails 31 slide through the inlet 4 and outlet 5 on the heating box 2. Multiple push blocks 32 are evenly bolted on the feeding rails 31 along their length. The leaf spring 0 is located between two adjacent push blocks 32. The push blocks 32 are used to clamp the leaf spring 0.

[0040] Reference Figure 1 , Figure 2and Figure 3 The processing table 1 is equipped with a separation and combination assembly 7 that drives the two material conveying rails 31 to separate or move closer to each other, and a drive assembly 8 that drives the material conveying rails 31 to slide along the axis of the support rod 6.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The splitting and joining assembly 7 includes a first bidirectional screw 71 and a second bidirectional screw 72 rotatably connected to the processing table 1. The first bidirectional screw 71 and the second bidirectional screw 72 are located at both ends of the length direction of the feeding rail 31, and both ends of the first bidirectional screw 71 are threadedly connected to a first sliding plate 73.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The two ends of the second bidirectional screw 72 are threadedly connected to the second slide plate 74. The first slide plate 73 and the second slide plate 74 are both slidably engaged with the processing table 1. The first slide plate 73 and the second slide plate 74 are respectively arranged at both ends of the length direction of the conveying rail 31. A rotating component 75 is arranged on the processing table 1. The rotating component 75 is used to drive the first bidirectional screw 71 and the second bidirectional screw 72 to rotate synchronously.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The rotating component 75 includes a splitting motor 751 bolted to the processing table 1 and electrically connected to the control system. The splitting motor 751 can be a forward and reverse motor in the prior art. A splitting shaft 752 is coaxially bolted to the output shaft of the splitting motor 751. Gearboxes 753 for transmitting torque are arranged between the splitting shaft 752 and the first bidirectional screw 71, and between the splitting shaft 752 and the second bidirectional screw 72. The gearboxes 753 contain meshing gears (not shown in the figure).

[0044] Reference Figure 1 , Figure 2 and Figure 3 The drive assembly 8 includes a reciprocating slide rail 81 bolted to the processing table 1 and parallel to the length direction of the conveying rail 31. A push plate 82 slides on the reciprocating slide rail 81. A loading cylinder 20 electrically connected to the control system is bolted to the processing table 1 between the push plate 82 and the heating box 2. A material placement rack 21 is welded to the piston rod of the loading cylinder 20. The material placement rack 21 is located between the two conveying rails 31. A leaf spring 0 is placed on the material placement rack 21.

[0045] Reference Figure 1 , Figure 2 and Figure 3The feeding rail 31 is slidably engaged with the first slide plate 73 and the second slide plate 74 and slides along the length of the feeding rail 31. The end of the feeding rail 31 is bolted with a sliding block 23 for sliding engagement with the first slide plate 73 or the second slide plate 74. Two connecting blocks 83 are slidably connected on the push plate 82 along the axis of the first bidirectional screw 71. The connecting blocks 83 are bolted to the feeding rail 31 and correspond one-to-one with the feeding rail 31. A push screw 84 is rotatably connected to the processing table 1, and the push plate 82 is threadedly connected to the push screw 84.

[0046] Reference Figure 1 , Figure 2 and Figure 3 The processing table 1 is provided with a reciprocating component 85 that drives the push screw 84 to rotate. The reciprocating component 85 includes a reciprocating motor 851 that is bolted to the processing table 1 and electrically connected to the control system. The reciprocating motor 851 can be a forward and reverse motor in the prior art. Synchronous pulleys 852 are welded to both the output shaft of the reciprocating motor 851 and the push screw 84. A synchronous belt 853 is wound between the synchronous pulley 852 on the output shaft of the reciprocating motor 851 and the synchronous pulley 852 on the push screw 84.

[0047] The worker places the leaf spring 0 on the material rack 21, and then the control system starts the loading cylinder 20. The piston rod of the loading cylinder 20 retracts and drives the leaf spring 0 on the material rack 21 to descend, so that the leaf spring 0 is flush with the material conveying rail 31. Then the control system starts the splitting motor 751.

[0048] The output shaft of the splitting and engaging motor 751 drives the splitting and engaging shaft 752 to rotate in the forward direction. Through the gearbox 753, the first bidirectional screw 71 and the second bidirectional screw 72 rotate in the forward direction simultaneously, thereby bringing the two conveying rails 31 closer to each other. The push block 32 on the conveying rail 31 clamps the leaf spring 0 on the material rack 21. Then, the control system starts the reciprocating motor 851. The output shaft of the reciprocating motor 851 rotates the push screw 84 in the forward direction through the synchronous pulley 852 and the synchronous belt 853.

[0049] Under the constraint of the reciprocating slide rail 81, the push screw 84 drives the push plate 82 to slide, thereby moving the leaf spring 0 on the material rack 21 to the support ceramic 22 on the support rod 6 by the material conveying rail 31. Then, the control system controls the output shaft of the split motor 751 to rotate in the direction of rotation, and then controls the output shaft of the reciprocating motor 851 to rotate in the opposite direction, thereby realizing a complete process of moving the leaf spring 0 on the material rack 21 into the heating box 2, and then repeating the operation.

[0050] As the leaf spring 0 moves within the heating chamber 2, the heating coil 9 heats the leaf spring 0, while the temperature measuring instrument 11 measures the temperature of the heated leaf spring 0 through the temperature measuring port 12, thereby ensuring that each leaf spring 0 that slides out of the discharge port 5 of the heating chamber 2 is heated at the same temperature.

[0051] Reference Figure 1 , Figure 2 and Figure 4 A material-picking base 13 is bolted to the processing table 1. A material-picking plate 14 is slidably arranged on the material-picking base 13. A material-picking cylinder 15, which is electrically connected to the control system, is bolted to the material-picking base 13. The material-picking plate 14 is welded to the piston rod of the material-picking cylinder 15. A material-picking claw 16 is rotatably connected to the material-picking plate 14. The material-picking claw 16 is used to rotate and lift the heated leaf spring 0. A plate-picking component 17 that drives the material-picking claw 16 to rotate is arranged on the material-picking plate 14.

[0052] Reference Figure 1 , Figure 2 and Figure 4 The plate-retrieving component 17 includes a rotating plate cylinder 171 bolted to the plate 14 and electrically connected to the control system. A drive rod 172 is welded to the piston rod of the rotating plate cylinder 171. A guide groove 173 for the drive rod 172 to slide is provided on the plate 14 along the axis of the piston rod of the rotating plate cylinder 171. An inclined slot 174 for the drive rod 172 to slide is provided on the pick-up claw 16. The inclined slot 174 is inclined towards the rotating plate cylinder 171 in a downward direction.

[0053] Reference Figure 1 , Figure 2 and Figure 4 A vertically sliding extraction frame 18 is arranged on the processing table 1 and on the side of the discharge port 5 near the heating box 2. The extraction frame 18 is located directly below the material picking claw 16. A lifting cylinder 19, which is electrically connected to the control system, is bolted to the processing table 1. The extraction frame 18 is welded to the piston rod of the lifting cylinder 19.

[0054] When the feeding rail 31 moves the heated leaf spring 0 to the outside of the heating box 2 by clamping the heated leaf spring 0 with the push block 32, the control system starts the picking cylinder 15. The output shaft of the picking cylinder 15 drives the picking plate 14 to approach the heated leaf spring 0. At this time, the picking claw 16 is located below the leaf spring 0. As the two feeding rails 31 separate from each other, the leaf spring 0 inside the heating box 2 falls on the supporting ceramic 22, and the leaf spring 0 outside the heating box 2 falls on the picking claw 16.

[0055] Then the control system starts the rotating plate cylinder 171. The piston rod of the rotating plate cylinder 171 extends and drives the drive rod 172 to slide along the length direction of the guide groove 173. Since there is an angle between the inclined groove 174 and the guide groove 173, when the drive rod 172 slides, the relative sliding between the drive rod 172 and the guide groove 173 causes the picking claw 16 to rotate around its rotation center, thereby making the picking claw 16 lift the leaf spring 0, so as to facilitate the subsequent equipment to pick up the leaf spring 0.

[0056] When it is necessary to sample and inspect the performance of the heated leaf spring 0, the control system activates the lifting cylinder 19. The piston rod of the lifting cylinder 19 pushes the extraction frame 18 to rise. The extraction frame 18 lifts the leaf spring 0 that has fallen on the picking claw 16. Then the picking cylinder 15 controls the picking plate 14 to reset. After that, the lifting cylinder 19 drives the heated leaf spring 0 to fall through the extraction frame 18. The heated leaf spring 0 cools naturally on the extraction frame 18, thus completing the sampling process.

[0057] The implementation principle of the leaf spring 0 heating machine in this application embodiment is as follows: the worker places the leaf spring 0 on the material rack 21, and then the control system starts the material loading cylinder 20. The piston rod of the material loading cylinder 20 retracts and drives the leaf spring 0 on the material rack 21 to descend, so that the leaf spring 0 is flush with the material conveying rail 31. Then the control system starts the splitting motor 751.

[0058] The output shaft of the splitting and engaging motor 751 drives the splitting and engaging shaft 752 to rotate in the forward direction. Through the gearbox 753, the first bidirectional screw 71 and the second bidirectional screw 72 rotate in the forward direction simultaneously, thereby bringing the two conveying rails 31 closer to each other. The push block 32 on the conveying rail 31 clamps the leaf spring 0 on the material rack 21. Then, the control system starts the reciprocating motor 851. The output shaft of the reciprocating motor 851 rotates the push screw 84 in the forward direction through the synchronous pulley 852 and the synchronous belt 853.

[0059] Under the constraint of the reciprocating slide rail 81, the push screw 84 drives the push plate 82 to slide, thereby moving the leaf spring 0 on the material rack 21 to the support ceramic 22 on the support rod 6 by the material conveying rail 31. Then, the control system controls the output shaft of the split motor 751 to rotate in the direction of rotation, and then controls the output shaft of the reciprocating motor 851 to rotate in the opposite direction, thereby realizing a complete process of moving the leaf spring 0 on the material rack 21 into the heating box 2, and then repeating the operation.

[0060] As the leaf spring 0 moves within the heating chamber 2, the heating coil 9 heats the leaf spring 0, while the temperature measuring instrument 11 measures the temperature of the heated leaf spring 0 through the temperature measuring port 12, thereby ensuring that each leaf spring 0 that slides out of the discharge port 5 of the heating chamber 2 is heated at the same temperature.

[0061] When the feeding rail 31 moves the heated leaf spring 0 to the outside of the heating box 2 by clamping the heated leaf spring 0 with the push block 32, the control system starts the picking cylinder 15. The output shaft of the picking cylinder 15 drives the picking plate 14 to approach the heated leaf spring 0. At this time, the picking claw 16 is located below the leaf spring 0. As the two feeding rails 31 separate from each other, the leaf spring 0 inside the heating box 2 falls on the supporting ceramic 22, and the leaf spring 0 outside the heating box 2 falls on the picking claw 16.

[0062] Then the control system starts the rotating plate cylinder 171. The piston rod of the rotating plate cylinder 171 extends and drives the drive rod 172 to slide along the length direction of the guide groove 173. Since there is an angle between the inclined groove 174 and the guide groove 173, when the drive rod 172 slides, the relative sliding between the drive rod 172 and the guide groove 173 causes the picking claw 16 to rotate around its rotation center, thereby making the picking claw 16 lift the leaf spring 0, so as to facilitate the subsequent equipment to pick up the leaf spring 0.

[0063] When it is necessary to sample and inspect the performance of the heated leaf spring 0, the control system activates the lifting cylinder 19. The piston rod of the lifting cylinder 19 pushes the extraction frame 18 to rise. The extraction frame 18 lifts the leaf spring 0 that has fallen on the picking claw 16. Then the picking cylinder 15 controls the picking plate 14 to reset. After that, the lifting cylinder 19 drives the heated leaf spring 0 to fall through the extraction frame 18. The heated leaf spring 0 cools naturally on the extraction frame 18, thus completing the sampling process.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
