Description

Technical Field

[0001] The invention relates to a device for transferring metal bars after quenching. Background Art

[0002] Metal bar quenching is an important heat treatment process, and its main function is to change the metal's structure and properties through rapid cooling to meet specific engineering requirements, such as increasing hardness, increasing strength, and improving wear resistance. At present, metal bars need to be sent to a tempering furnace for tempering after quenching, and at this time, a metal bar transfer device is needed.

[0003] The metal bar placement structure in the existing metal bar transfer device is mostly a fixed structure, which cannot be adjusted with the length of the metal bar, which leads to instability when placing longer metal bars or a large space occupied by the placement structure when placing shorter metal bars, reducing the practicability and transfer flexibility of the device. When the metal bar is moved from the transfer device to the feeding end of the tempering furnace, it is mostly moved by clamping the metal bar by a manipulator, which is troublesome to unload, and clamping the metal bar easily causes the metal bar to deform. Therefore, in view of the above technical problems, a transfer device for metal bars after quenching is proposed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention proposes a device for transferring metal bars after quenching. The placement structure is convenient for adjustment according to the length of the metal bars, thereby improving the practicality and transfer flexibility of the device, facilitating the movement of the metal bars to the feed end of the tempering furnace, facilitating unloading and avoiding deformation of the metal bars.

[0005] A device for transferring metal bars after quenching, comprising:

[0006] A mobile flat car with a fixed seat at the top;

[0007] A mounting frame, rotatably arranged on the top of the fixing seat around the length direction of the movable flat car;

[0008] A first driving assembly is disposed on the mobile flat car and connected to the mounting frame, and the first driving assembly is adjusted to drive the mounting frame to rotate; and

The multiple groups of V-shaped support frames are arranged in an array that can slide along the length direction of the movable flat car at the top of the mounting frame. The spring connects the multiple groups of V-shaped support frames. The second drive component is set on the mounting frame and connected to both ends of the spring. Adjusting the second drive component can drive the spring to extend or shorten.

[0010] The beneficial effects of the above-mentioned quenched metal bar transfer device are:

[0011] The spring is driven by the second driving component to elongate or shorten. When the spring elongates, it can drive the multi-group V-shaped support frames to move away from each other. When the spring shortens, it can drive the multi-group V-shaped support frames to move closer to each other. The distance between the multi-group V-shaped support frames moving away from or closer to each other can be adjusted according to the length of the metal bar stock, improving the stability when placing longer metal bar stocks and reducing the occupied space when placing shorter metal bar stocks, enhancing the practicability and transfer flexibility of the device. At the same time, when the multi-group V-shaped support frames move away from or closer to each other, the support points for the metal bar stock are evenly distributed, avoiding deformation of the metal bar stock during the transfer process. By driving the first driving component to rotate the mounting frame, when the mounting frame rotates to make the middle of the multi-group V-shaped support frames higher than one end, at this time, the metal bar stock can roll along the multi-group V-shaped support frames onto the feeding end of the tempering furnace.

[0036] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0037] Please refer to Figures 1 to 3 , a transfer device for metal bar stock after quenching in one embodiment, includes a mobile flat car 10, a mounting frame 20, a first driving component, and a placement structure.

[0038] Among them, a fixed seat 101 is provided at the top of the mobile flat car 10. The mounting frame 20 is rotatably arranged at the top of the fixed seat 101 around the length direction of the mobile flat car 10. The first driving component is arranged on the mobile flat car 10 and is connected to the mounting frame 20. Adjusting the first driving component can drive the mounting frame 20 to rotate. The placement structure includes a second driving component, a spring 301, and multiple groups of V-shaped support frames 30. The multiple groups of V-shaped support frames 30 are arranged in an array along the length direction of the mobile flat car 10 and are slidable on the top of the mounting frame 20. The spring 301 connects the multiple groups of V-shaped support frames 30. The second driving component is arranged on the mounting frame 20 and is connected to both ends of the spring 301. Adjusting the second driving component can drive the spring 301 to extend or shorten.

[0039] In the above embodiment, by driving the spring 301 to extend or shorten through the second driving component, when the spring 301 extends, it can drive the multiple groups of V-shaped support frames 30 to move away from each other, and when the spring 301 shortens, it can drive the multiple groups of V-shaped support frames 30 to move closer to each other. The distance between the multiple groups of V-shaped support frames 30 moving away from or closing together can be adjusted according to the length of the metal bar stock, improving the stability when placing longer metal bar stocks and reducing the occupied space when placing shorter metal bar stocks, enhancing the practicability and transfer flexibility of the device. At the same time, when the distance between the multiple groups of V-shaped support frames 30 moves away from or closes together, the support points for the metal bar stock are evenly distributed, avoiding deformation of the metal bar stock during the transfer process.

[0040] During feeding, the mobile flat car 10 is used to align the multiple groups of V-shaped support frames 30 with the discharge end 1 of the quenching device. At this time, the discharge end 1 of the quenching device can move the quenched metal bar stock onto the multiple groups of V-shaped support frames 30. Then, the mobile flat car 10 is used to move the multiple groups of V-shaped support frames 30 to one side of the feed end 2 of the tempering furnace. Then, by driving the first driving component, the mounting frame 20 is rotated. The rotation of the mounting frame 20 drives the multiple groups of V-shaped support frames 30 to rotate. When the multiple groups of V-shaped support frames 30 rotate so that the middle is higher than one end, at this time, the metal bar stock can roll down along the multiple groups of V-shaped support frames 30 to the feed end 2 of the tempering furnace. There is no need to clamp the metal bar stock, and the discharging is convenient, avoiding deformation of the metal bar stock.

[0041] Please refer to Figure 1 , Figure 3 and Figure 4, in one embodiment, the first driving assembly includes a first worm gear 40, a first worm 401 and a first motor 402; connecting shafts 201 are oppositely arranged at both ends of the bottom of the mounting bracket 20, and the two groups of connecting shafts 201 are rotatably arranged at the top end of the fixed seat 101 around the length direction of the moving flat car 10. A first worm gear 40 is coaxially arranged on one group of connecting shafts 201, the first worm 401 is rotatably arranged on the fixed seat 101 and meshes with the first worm gear 40, the first motor 402 is arranged on the fixed seat 101, and the output end is coaxially connected with the first worm 401.

[0042] In the above embodiment, the first motor 402 drives the first worm 401 to rotate. When the first worm 401 rotates and meshes with the first worm gear 40, it can drive the first worm gear 40 to rotate. The rotation of the first worm gear 40 drives the connecting shaft 201 to rotate, and the rotation of the connecting shaft 201 drives the mounting bracket 20 to rotate. It is convenient to drive the mounting bracket 20 to rotate, and the cooperation between the first worm 401 and the first worm gear 40 has self-locking property, that is, stopping the first motor 402 from driving the first worm 401 to rotate can fix the mounting bracket 20, and it is convenient to fix the mounting bracket 20. It can be understood that driving the first worm 401 to rotate in the reverse direction by the first motor 402 can drive the mounting bracket 20 to rotate in the reverse direction to reset.

[0043] Please refer to Figure 1 , in one embodiment, a plurality of hydraulic telescopic columns 102 are arranged at intervals along the length direction of the top end of the moving flat car 10, and the fixed seat 101 is arranged on the moving flat car 10 in a liftable manner through the plurality of hydraulic telescopic columns 102. By controlling the lifting of the plurality of hydraulic telescopic columns 102, the height of the plurality of V-shaped support frames 30 can be adjusted, so as to facilitate the adjustment according to the heights of the discharging end 1 of the quenching device and the feeding end 2 of the tempering furnace, thereby improving the practicability of the device.

[0044] Please refer to Figure 1 , Figure 5 and Figure 6 , in one embodiment, the second driving assembly includes a bidirectional screw 302, a guide block 303 and a second motor 304; a guide groove 202 is formed at the top end of the mounting bracket 20, two groups of guide blocks 303 are slidably arranged in the guide groove 202 along the length direction of the moving flat car 10, the two groups of guide blocks 303 are respectively connected to both ends of the spring 301, the bidirectional screw 302 is rotatably arranged in the guide groove 202, and both ends are respectively threadedly connected to the two groups of guide blocks 303. The second motor 304 is arranged on the mounting bracket 20, and the output end is coaxially connected to the bidirectional screw 302.

[0045] In the above embodiments, the second motor 304 drives the bidirectional screw 302 to rotate. When the bidirectional screw 302 rotates and is in threaded engagement with the two guide blocks 303, the two guide blocks 303 can be driven to move relatively away from each other. When the two guide blocks 303 move relatively away from each other, the spring 301 can be extended. Conversely, when the second motor 304 drives the bidirectional screw 302 to rotate in the reverse direction, and the bidirectional screw 302 rotates in the reverse direction and is in threaded engagement with the two guide blocks 303, the two guide blocks 303 can be driven to move relatively closer to each other. When the two guide blocks 303 move relatively closer to each other, the spring 301 can be shortened. It is convenient to drive the spring 301 to extend or shorten. Moreover, when the rotation of the bidirectional screw 302 stops, the bidirectional screw 302 and the two guide blocks 303 are in threaded engagement to fix the two guide blocks 303, thereby fixing the length of the spring 301, and it is convenient to fix the length of the spring 301.

[0046] Please refer to Figure 1 、 Figure 5 、 Figure 7 and Figure 8 In one embodiment, the placing structure further includes an adjusting assembly; the V-shaped support frame 30 includes a mounting block 305 and a support rod 306. The mounting block 305 is slidably arranged at the top of the mounting frame 20 along the length direction of the moving flat car 10 and is connected to the spring 301. Two support rods 306 are hinged oppositely at the top of the mounting block 305. The two support rods 306 cooperate to form a V shape. The adjusting assembly is arranged on the mounting frame 20 and is connected to the two support rods 306 in each V-shaped support frame 30 for driving the two support rods 306 in each V-shaped support frame 30 to rotate synchronously outward or close together.

[0047] In the above embodiments, by driving the two support rods 306 in each V-shaped support frame 30 to rotate synchronously outward through the adjusting assembly, the angle formed by the cooperation of the two support rods 306 to form a V shape can be increased, which is convenient for improving the stability of multiple V-shaped support frames 30 when placing relatively thick metal rod materials. By driving the two support rods 306 in each V-shaped support frame 30 to rotate synchronously and close together through the adjusting assembly, the angle formed by the cooperation of the two support rods 306 to form a V shape can be reduced, which is convenient for reducing the occupied space of multiple V-shaped support frames 30 when placing relatively thin metal rod materials, and further improves the practicability and transfer flexibility of the device.

[0048] Specifically in the above embodiments, first limiting grooves 203 are provided on both sides of the mounting frame 20, and first limiting blocks 3051 are provided at both ends of the mounting block 305. The two first limiting blocks 3051 are slidably arranged in the two first limiting grooves 203 along the length direction of the moving flat car 10. The cooperation of the first limiting grooves 203 and the first limiting blocks 3051 can improve the sliding stability of the mounting block 305.

[0049] Please refer to Figure 1 、 Figure 7 and Figure 8, In one embodiment, the adjusting assembly includes a rotating shaft 50, a gear 501, and a third driving assembly; the rotating shaft 50 is arranged along the length direction of the mobile flatbed 10 and is rotatably arranged on the mounting frame 20. Gears 501 are coaxially arranged on the hinge shafts of multiple groups of support rods 306. Two gears 501 in the same V-shaped support frame 30 are meshed with each other. Among multiple groups of V-shaped support frames 30, multiple support rods 306 on one side are all slidably sleeved on the rotating shaft 50 along the length direction of the mobile flatbed 10. The rotating shaft 50 is coaxial with the hinge shafts of multiple support rods 306 on one side. The third driving assembly is arranged on the mounting frame 20 and is connected to the rotating shaft 50 for driving the rotating shaft 50 to rotate.

[0050] In the above embodiment, the third driving assembly drives the rotating shaft 50 to rotate. The rotation of the rotating shaft 50 drives the rotation of multiple connected support rods 306. The rotation of multiple support rods 306 on this side can drive the reverse rotation of multiple support rods 306 on the other side through the meshing of corresponding two gears 501, which is convenient for driving the synchronous outward expansion or closing rotation of two support rods 306 in each V-shaped support frame 30.

[0051] Specifically in the above embodiment, among multiple groups of V-shaped support frames 30, two second limiting grooves 3061 are relatively formed on multiple support rods 306 on one side. Two second limiting blocks 502 are relatively arranged on the circumferential side of the rotating shaft 50. The two second limiting grooves 3061 are slidably sleeved on the two second limiting blocks 502 along the length direction of the mobile flatbed 10. The cooperation between the second limiting groove 3061 and the second limiting block 502 can improve the stability of the rotating shaft 50 driving the support rod 306 to rotate.

[0052] Please refer to Figure 1 、 Figure 7 and Figure 8 , In one embodiment, the third driving assembly includes a second worm gear 503, a second worm 504, and a third motor 505; the second worm gear 503 is coaxially arranged on the rotating shaft 50, the second worm 504 is rotatably arranged on the mounting frame 20 and is meshed with the second worm gear 503, and the third motor 505 is arranged on the mounting frame 20 and its output end is coaxially connected to the second worm 504.

[0053] In the above embodiment, the third motor 505 drives the second worm 504 to rotate. The rotation of the second worm 504 meshes with the second worm gear 503 to drive the second worm gear 503 to rotate. The rotation of the second worm gear 503 can drive the rotating shaft 50 to rotate, which is convenient for driving the rotating shaft 50 to rotate. And when the third motor 505 stops, the cooperation between the second worm 504 and the second worm gear 503 forms a self-locking to fix the rotating shaft 50, which is convenient for fixing the rotating shaft 50.

[0054] Please refer to Figure 1, In one embodiment, a push frame 103 is inclined at one end of the mobile flatbed 10, and the high end of the push frame 103 is away from the V-shaped support frame 30. By providing the push frame 103, it is convenient to push the mobile flatbed 10 to move, and the operator can be kept away from the metal bar stock on the V-shaped support frame 30, improving the safety of the moving device.

[0055] The specific implementation manner of the above-mentioned transfer device for quenched metal bar stock is as follows:

[0056] Driving the bidirectional screw 302 to rotate by the second motor 304, the rotation of the bidirectional screw 302 and the threaded engagement with the two groups of guide blocks 303 can drive the two groups of guide blocks 303 to move relatively away from each other. When the two groups of guide blocks 303 move relatively away from each other, the spring 301 can be elongated. Conversely, driving the bidirectional screw 302 to rotate in the reverse direction by the second motor 304, the reverse rotation of the bidirectional screw 302 and the threaded engagement with the two groups of guide blocks 303 can drive the two groups of guide blocks 303 to move relatively closer to each other. When the two groups of guide blocks 303 move relatively closer to each other, the spring 301 can be shortened. It is convenient to drive the spring 301 to elongate or shorten. When the spring 301 elongates, it can drive the multi-group V-shaped support frames 30 to move away from each other at intervals. When the spring 301 shortens, it can drive the multi-group V-shaped support frames 30 to move closer together at intervals. The multi-group V-shaped support frames 30 moving away from or closing together at intervals can be adjusted according to the length of the metal bar stock, improving the stability when placing longer metal bar stocks and reducing the occupied space when placing shorter metal bar stocks, enhancing the practicability and transfer flexibility of the device. At the same time, when the multi-group V-shaped support frames 30 move away from or close together at intervals, the support points for the metal bar stock are evenly distributed, avoiding deformation of the metal bar stock during the transfer process.

[0057] During loading, the multi-group V-shaped support frames 30 are aligned with the discharging end 1 of the quenching device by the mobile flatbed 10. At this time, the discharging end 1 of the quenching device can move the quenched metal bar stock onto the multi-group V-shaped support frames 30. Then, the multi-group V-shaped support frames 30 are moved to one side of the feeding end 2 of the tempering furnace by the mobile flatbed 10. Then, driving the first worm 401 to rotate by the first motor 402, the rotation of the first worm 401 and the engagement with the first worm gear 40 can drive the first worm gear 40 to rotate. The rotation of the first worm gear 40 drives the connecting shaft 201 to rotate. The rotation of the connecting shaft 201 drives the mounting frame 20 to rotate. The rotation of the mounting frame 20 drives the multi-group V-shaped support frames 30 to rotate. When the multi-group V-shaped support frames 30 rotate to make the middle part higher than one end, stop the first motor 402 to fix the mounting frame 20. At this time, the metal bar stock can roll down along the multi-group V-shaped support frames 30 to the feeding end 2 of the tempering furnace. There is no need to clamp the metal bar stock, and the unloading is convenient, avoiding deformation of the metal bar stock.
