Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for forging production, specifically to a small automatic forging transfer device. Background Technology

[0002] In the production of small forgings such as bolt blanks and gear blanks, the forged workpieces need to be transferred from the forging press workbench to the cooling zone, inspection zone or the next process station.

[0003] However, existing transfer methods have the following main problems: traditional robotic arms use fixed clamping structures, which can only be adapted to single-specification forgings. When changing the forging model, the clamps need to be disassembled and replaced, which takes a long time to adjust and cannot meet the needs of multi-variety small-batch production. In addition, the surface temperature of the forging is high when it is just finished forging, and there may be oxide scale on the surface. The existing rigid clamping structure is prone to causing indentations or oxide scale to fall off the surface of the forging, affecting product quality. At the same time, there is no buffer positioning mechanism during the transfer process. When the forging is placed, it is easy to have a hard collision with the receiving station, which will cause the station to shift or the forging to move. Subsequent processes need to be recalibrated. Therefore, we propose a small automatic forging transfer device. Utility Model Content

[0004] In view of the problems existing in the above-mentioned small forging automatic transfer device, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a small automatic transfer device for forgings, which solves the following problems of existing transfer methods: traditional robotic arms use a fixed clamping structure, which can only be adapted to a single specification of forgings. When changing the forging model, the clamps need to be disassembled and replaced, which takes a long time to adjust and cannot meet the needs of multi-variety small-batch production. In addition, the surface temperature of the forging is high when it is just finished forging, and there may be oxide scale on the surface. The existing rigid clamping structure is prone to causing indentations or oxide scale to fall off the surface of the forging, affecting product quality. At the same time, there is no buffer positioning mechanism during the transfer process. When the forging is placed, it is easy to have a hard collision with the receiving station, which will cause the station to shift or the forging to move, and subsequent processes need to recalibrate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A small-scale automatic forging transfer device includes a track frame, guide rails, and a movable seat. Guide rails are fixedly installed at both ends of the top surface of the track frame. Guide grooves are provided on opposite sides of the two guide rails. A movable seat slides between the two guide rails. Guide wheels are rotatably installed at both ends of the bottom of the movable seat, and the two guide wheels are slidably connected to the interior of the two guide grooves respectively. A fixed cylinder is fixedly installed on the top of the movable seat. A lifting column slides inside the fixed cylinder. A lifting platform is fixedly installed on the top of the lifting column. A first motor is fixedly installed on the top of the lifting platform. A reduction gearbox is fixedly installed at the output end of the first motor. A rotating platform is fixedly installed at the output end of the reduction gearbox.

[0007] Preferably, a fixing plate is fixedly installed on both sides of the top of the rotating platform, and a miniature cylinder is provided through the surface of each of the two fixing plates. An arc-shaped clamping plate is fixedly installed at the output end of each of the two miniature cylinders.

[0008] Preferably, a hydraulic cylinder is fixedly installed inside the fixed cylinder, the output end of the hydraulic cylinder is fixedly connected to the bottom of the lifting column, and the surface of the lifting column is provided with scale markings.

[0009] Preferably, mounting plates are fixedly installed on both sides of the opposite ends of the two guide rails, a ball screw is rotatably provided between the two mounting plates, a screw nut is fixedly installed at the bottom of the movable seat, and the screw nut is threadedly connected to the ball screw.

[0010] Preferably, limit buffers are fixedly installed on both sides inside the two guide grooves, and high-temperature resistant silicone pads are fixedly installed on the opposite side of the two arc-shaped clamping plates.

[0011] Preferably, a second motor is fixedly mounted on the surface of one side of the mounting plate, and the output end of the second motor is fixedly connected to one side of the ball screw.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention uses a miniature cylinder to drive the arc-shaped clamping plate to move, allowing the clamping distance to be adjusted according to the forging specifications without disassembling or replacing the clamps. It is suitable for small forgings of different diameters and sizes, meeting the needs of multi-variety, small-batch production and significantly reducing the adjustment time when changing forging models. At the same time, the high-temperature resistant silicone pad fixed on the inner side of the arc-shaped clamping plate can withstand the high temperature after the forging is pressed, preventing high temperature damage to the clamping components. Furthermore, by replacing the traditional rigid clamping with flexible contact, it effectively prevents indentations on the surface of the forging and avoids the oxide scale on the surface of the forging from falling off due to rigid extrusion, thus ensuring the appearance and performance quality of the forging.

[0013] This invention utilizes a ball screw and screw nut threaded transmission structure, combined with the sliding guidance of guide wheels and guide grooves, to ensure precise movement of the moving seat along the guide rail. A hydraulically driven lifting column, combined with graduated markings, precisely controls the height of the lifting platform. A first motor, in conjunction with a reduction gearbox, drives the rotating platform to achieve precise adjustment of the forging angle. Furthermore, a limit buffer within the guide groove prevents the moving seat from overtraveling and colliding, further ensuring the accuracy of the forging placement and reducing calibration work in subsequent processes. Simultaneously, through the coordinated control of the second motor, hydraulic cylinder, first motor, and micro-cylinder, the entire forging transfer process is automated, eliminating the need for manual gripping and handling of forgings. This not only reduces the labor intensity of workers but also avoids errors that may occur during manual operation, improving transfer efficiency. Attached Figure Description

[0018] This utility model discloses a small automatic forging transfer device.

[0019] This utility model provides, for example Figure 1-4The illustrated small-scale automatic forging transfer device includes a track frame 1, guide rails 2, and a movable seat 3. Guide rails 2 are fixedly installed at both ends of the top surface of the track frame 1. Guide grooves 4 are provided on opposite sides of the two guide rails 2. A movable seat 3 is slidably disposed between the two guide rails 2. Guide wheels 5 are rotatably disposed at both ends of the bottom of the movable seat 3, and the two guide wheels 5 are slidably connected to the interior of the two guide grooves 4 respectively. A fixed cylinder 6 is fixedly installed on the top of the movable seat 3. A lifting column 7 is slidably disposed inside the fixed cylinder 6. A lifting platform 8 is fixedly installed on the top of the lifting column 7. A first motor 9 is fixedly installed on the top of the lifting platform 8. A reduction gearbox 10 is fixedly installed at the output end of the first motor 9. A rotating platform 11 is fixedly installed at the output end of the reduction gearbox 10 to facilitate adjustment of the position of the arc-shaped clamping plate 14.

[0020] This utility model discloses a small automatic forging transfer device. The rotating platform 11 has fixed plates 12 fixedly installed on both sides of its top. The surfaces of the two fixed plates 12 are provided with miniature cylinders 13. The output ends of the two miniature cylinders 13 are fixedly installed with arc-shaped clamping plates 14, which facilitates clamping forgings of different specifications.

[0021] This utility model discloses a small automatic forging transfer device. A hydraulic cylinder 15 is fixedly installed inside the fixed cylinder 6. The output end of the hydraulic cylinder 15 is fixedly connected to the bottom of the lifting column 7. The surface of the lifting column 7 is provided with scale markings 16 to facilitate the adjustment of the height of the arc-shaped clamping plate 14.

[0022] This utility model discloses a small automatic forging transfer device. Mounting plates 17 are fixedly installed on both sides of the opposite ends of the two guide rails 2. A ball screw 18 is rotatably provided between the two mounting plates 17. A screw nut 19 is fixedly installed at the bottom of the movable seat 3. The screw nut 19 is threadedly connected to the ball screw 18, which facilitates the adjustment of the position of the movable seat 3.

[0023] This utility model discloses a small automatic forging transfer device. Limit buffers 20 are fixedly installed on both sides inside the two guide grooves 4, and high-temperature resistant silicone pads 21 are fixedly installed on the opposite side of the two arc-shaped clamping plates 14. This not only avoids damage to high-temperature forgings, but also ensures clamping stability and solves the problem of indentation caused by traditional rigid clamping.

[0024] This utility model discloses a small automatic forging transfer device, wherein a second motor 22 is fixedly installed on the surface of the mounting plate 17 on one side, and the output end of the second motor 22 is fixedly connected to one side of the ball screw 18.

[0025] During use, the second motor 22 starts and drives the ball screw 18 to rotate. The screw nut 19, which is threaded to the ball screw 18, then drives the moving seat 3 to slide along the guide rail 2. The guide wheel 5 at the bottom of the moving seat 3 slides in the guide groove 4 of the guide rail 2 to ensure stable movement until the moving seat 3 moves to the forging gripping position next to the forging press workbench. At the same time, the hydraulic cylinder 15 in the fixed cylinder 6 starts, pushing the lifting column 7 to slide up or down along the fixed cylinder 6. Combined with the scale markings 16 on the surface of the lifting column 7, the lifting platform 8 is adjusted to a gripping height that matches the height of the forging. After the height of the lifting platform 8 is calibrated, the miniature cylinders 13 on the fixed plates 12 on both sides of the top of the rotating platform 11 start synchronously, pushing the arc-shaped clamping plate 14 to move towards the forging. When the arc-shaped clamping plate 14 contacts the forging, the high-temperature resistant silicone pad 21 on its surface directly adheres to the surface of the forging, using the flexible properties of the silicone pad to wrap the forging. Meanwhile, the micro cylinder 13 maintains a stable output force to firmly clamp the forging. If the clamping angle of the forging needs to be adjusted to suit the subsequent workstation, the first motor 9 on the top of the lifting platform 8 can be started. The first motor 9 drives the rotating platform 11 to rotate through the reduction gearbox 10, adjusting the forging to the preset angle. After the forging is firmly clamped, the hydraulic cylinder 15 is started again, driving the lifting column 7 to rise and lifting the forging to a safe transfer height. Then, the second motor 22 drives the ball screw 18 to rotate in the opposite direction, driving the moving seat 3 to slide along the guide rail 2 to the target workstation such as the cooling area or the inspection area. After reaching the target workstation, the hydraulic cylinder 15 drives the lifting column 7 to descend, lowering the forging to the placement height. The micro cylinder 13 retracts, causing the arc-shaped clamping plate 14 to release, completing the placement of the forging. If the moving seat 3 approaches the end of the guide rail 2 during the placement process, the limit buffer 20 in the guide groove 4 can buffer and limit the moving seat 3 to prevent overtravel collision.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
