Description

Technical Field

[0001] This utility model belongs to the field of forging equipment technology, and specifically relates to a forging production line. Background Technology

[0002] Traditional friction press production lines have independent and dispersed equipment, with material placement areas, unloading areas, and production line areas being separate and dispersed. Materials are transferred between different processes using forklifts or overhead cranes, which wastes manpower, affects production efficiency, and the overlapping of transfer areas and employee passageways can easily lead to safety accidents.

[0003] The existing friction press production line relies heavily on manual labor. In the traditional operation, each process, including loading the billet, positioning the billet in the die cavity, controlling the friction press forging, transferring the billet in the pre-forging and final forging processes, and picking up the workpiece, is heavily dependent on manual labor, which limits production efficiency and capacity. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a forging production line that reduces manual intervention and centers the materials for easy subsequent robotic clamping.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A forging production line includes an intermediate frequency furnace, a pre-forging press, a final forging press, and a closed-type double-point press; the feeding end of the intermediate frequency furnace is provided with a feeding rack, the feeding rack is provided with a top material cylinder, and the discharging end of the intermediate frequency furnace is provided with a clamping and positioning device, which is used to center and position the material discharged from the discharging end of the intermediate frequency furnace. The pre-forging press, the final forging press, and the closed-type double-point press are arranged side by side. A first mobile robot is installed on one side of the pre-forging press and the final forging press; a second mobile robot is installed on one side of the final forging press and the closed double-point press.

[0006] The clamping and positioning device includes a positioning frame, a positioning guide rail, and a slide rail. The positioning guide rail and the slide rail are both fixedly mounted on the positioning frame. There is a gap between the positioning guide rail and the slide rail, and the positioning frame is provided with a groove at the corresponding gap. The slide rail is inclined, allowing materials to move along it to the positioning rail; the positioning frame is equipped with a centering and positioning mechanism.

[0007] The slide rail can be replaced by a chain conveyor.

[0008] The centering and positioning mechanism includes a first positioning plate and a second positioning plate. The first positioning plate is slidably connected to the positioning guide rail, and the second positioning plate is slidably connected to the slide rail. A driving mechanism is connected to the first positioning plate and the second positioning plate, which drives the first positioning plate and the second positioning plate to move relative to or away from each other. The second positioning plate has a through hole, and a baffle is slidably connected to the through hole. A drive cylinder is provided between the baffle and the second positioning plate.

[0009] The driving mechanism includes a bidirectional lead screw and a sliding sleeve. The bidirectional lead screw is rotatably connected to the positioning frame and is connected to a drive motor. There are two sliding sleeves, both of which are threadedly connected to the bidirectional lead screw. The first positioning plate and the second positioning plate are respectively fixedly connected to the corresponding sliding sleeves.

[0010] The first and second mobile robots have the same structure, both including a manipulator, a linear motion mechanism, and a moving base. The base of the manipulator is inserted into the moving base and fixed with bolts. The moving base is fixedly connected to the moving part of the linear motion mechanism. A positioning frame is provided outside the transmission belt. One side of the positioning frame is provided with an inspection port, and the other side of the positioning frame is provided with a push-out mechanism. The base of the manipulator can be pushed from the moving base to the inspection port through the push-out mechanism.

[0011] It also includes a transfer vehicle; the transfer vehicle can be moved to the inspection port; the transfer vehicle is equipped with a positioning cylinder, and the positioning frame is equipped with a positioning hole that cooperates with the positioning cylinder.

[0012] The transfer vehicle and its mobile base are equipped with slots for connecting to the base.

[0013] The ejection mechanism includes an ejection plate and an ejection cylinder. The ejection plate is slidably connected to the positioning frame, and the two ends of the ejection cylinder are fixedly connected to the positioning frame and the ejection plate, respectively.

[0014] Compared with the prior art, the advantages of this utility model are: The automatic transfer of bar stock between the pre-forging press, the final forging press, and the closed-loop dual-point press is achieved by using the first and second mobile robots, reducing manual operation, enabling the production line to operate continuously, and significantly improving production pace and overall efficiency.

[0015] The clamping and positioning device and its centering and positioning mechanism (including a first positioning plate, a second positioning plate and a drive mechanism) can accurately center and position the bar stock, ensuring that the first mobile robot always clamps the bar stock in the middle position and avoids tilting and falling off.

[0016] When a robotic arm malfunctions, it can be quickly pushed to the maintenance port via the ejection mechanism and removed for repair using a transfer vehicle, which greatly reduces downtime and improves the maintainability and availability of the production line. Attached Figure Description

Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0019] like Figures 1 to 6 As shown, a forging production line includes an intermediate frequency furnace 1, a pre-forging press 2, a final forging press 3, and a closed-type double-point press 4; the feeding end of the intermediate frequency furnace 1 is provided with a feeding rack 5, and a top-loading cylinder 6 is provided on the feeding rack 5. The bar stock (material) on the feeding rack 5 is pushed into the intermediate frequency furnace 1 through the top-loading cylinder 6.

[0020] A clamping and positioning device 7 is provided at the discharge end of the intermediate frequency furnace 1. The clamping and positioning device 7 is used to center and position the bar material discharged from the discharge end of the intermediate frequency furnace 1 so as to facilitate the subsequent clamping by the first mobile robot 8 and ensure that the clamping position is the middle position of the bar material.

[0021] The pre-forging press 2, the final forging press 3, and the closed-type double-point press 4 are arranged side by side. A first mobile robot 8 is provided on one side of the pre-forging press 2 and the final forging press 3; a second mobile robot 9 is provided on one side of the final forging press 3 and the closed-type double-point press 4.

[0022] The specific production process is as follows: After the bar stock is centered by the clamping and positioning device 7, it is clamped by the first mobile robot 8 and transferred to the pre-forging press 2 for pre-forging; after pre-forging, it is clamped by the first mobile robot 8 and transferred to the final forging press 3 for final forging; after final forging, it is transferred by the second mobile robot 9 to the closed double-point press 4 for punching. After punching, it can be transferred by the second mobile robot 9 to the required storage location.

[0023] Furthermore, the clamping and positioning device 7 includes a positioning frame 70, a positioning guide rail 71, and a slide rail 72. The positioning guide rail 71 and the slide rail 72 are both fixedly mounted on the positioning frame 70. There is a gap between the positioning guide rail 71 and the slide rail 72. The positioning frame 70 is provided with a groove 73 at the corresponding gap. The manipulator 10 of the first mobile robot 8 moves to the groove 73 to clamp the bar.

[0024] The slide rail 72 is inclined, and the top material cylinder 6 pushes the bar material into the medium frequency furnace 1 in sequence, and finally pushes the bar material out of the medium frequency furnace 1. The pushed bar material can move along the slide rail 72 to the positioning rail 71, and then the positioning frame 70 is equipped with a centering and positioning mechanism to center the bar material.

[0025] Furthermore, the aforementioned slide rail 72 is inclined, that is, the movement of the bar material is achieved by sliding; of course, mechanical conveying equipment such as chain conveyors can also be used instead.

[0026] Furthermore, the centering and positioning mechanism includes a first positioning plate 74 and a second positioning plate 75. The first positioning plate 74 is slidably connected to the positioning guide rail 71, and the second positioning plate 75 is slidably connected to the slide guide rail 72. A driving mechanism is connected to the first positioning plate 74 and the second positioning plate 75, which drives the first positioning plate 74 and the second positioning plate 75 to move relative to or away from each other. When the first positioning plate 74 and the second positioning plate move relative to each other, the bar stock can be clamped and centered. After centering, the first positioning plate 74 and the second positioning plate move back to their original positions.

[0027] The second positioning plate 75 has a through hole, and a baffle 76 is slidably connected to the through hole. A drive cylinder 77 is provided between the baffle 76 and the second positioning plate 75. When the bar is ejected, the piston rod of the drive cylinder 77 extends, causing the baffle 76 to move upward and expose the through hole, ensuring that the bar can move along the slide rail 72 to the positioning rail 71. After the bar is ejected, the piston rod of the drive cylinder 77 retracts, causing the baffle 76 to move downward and block the through hole. Finally, the bar is clamped and centered by the relative movement of the first positioning plate 74 and the second positioning plate.

[0028] Furthermore, the drive mechanism includes a bidirectional lead screw 78 and sliding sleeves 79. The bidirectional lead screw 78 is rotatably connected to the positioning frame 70, and a drive motor 710 is connected to the bidirectional lead screw 78. The housing of the drive motor 710 is fixedly connected to the positioning frame 70, and the output shaft of the drive motor 710 is fixedly connected to the bidirectional lead screw 78. Two sliding sleeves 79 are provided, each threadedly connected to the bidirectional lead screw 78. The first positioning plate 74 and the second positioning plate 75 are respectively fixedly connected to their corresponding sliding sleeves 79. By driving the bidirectional lead screw 78 to rotate through the drive motor 710, the two sliding sleeves 79 can move relative to or away from each other, thereby driving the first positioning plate 74 and the second positioning plate 75 to move relative to or away from each other.

[0029] Furthermore, the first mobile robot 8 and the second mobile robot 9 have the same structure, both including a manipulator 10, a linear motion mechanism 11, and a moving base 12. The base 21 of the manipulator 10 is inserted into and fixed to the moving base 12 with bolts; the moving base 12 is fixedly connected to the moving part of the linear motion mechanism 11; when the moving part of the linear motion mechanism 11 moves, it can drive the moving base 12 to move as well, thereby realizing the translation of the manipulator 10. Specifically, the linear motion mechanism 11 can be a lead screw slide or a linear motor.

[0030] A positioning frame 13 is provided outside the transmission belt. An inspection port 14 is provided on one side of the positioning frame 13, and a push-out mechanism is provided on the other side of the positioning frame 13. When the robot arm 10 malfunctions, the base 21 of the robot arm 10 can be pushed from the moving seat 12 to the inspection port 14 through the push-out mechanism.

[0031] Furthermore, it also includes a transfer cart 15; the transfer cart 15 can move to the inspection port 14; the transfer cart 15 is equipped with a positioning cylinder 16, and the positioning frame 13 is equipped with a positioning hole 17 that cooperates with the positioning cylinder 16. When the transfer cart 15 moves to the inspection port 14, the piston rod of the positioning cylinder 16 extends and inserts into the positioning hole 17, which can prevent the transfer cart 15 from moving during the operation of the push-out mechanism.

[0032] Furthermore, the transfer vehicle 15 and the mobile seat 12 are both provided with slots 18 that connect to the base 21, so that the connection between them can be achieved through the slots 18.

[0033] Furthermore, the ejection mechanism includes an ejection plate 19 and an ejection cylinder 20. The ejection plate 19 is slidably connected to the positioning frame 13, and the two ends of the ejection cylinder 20 are fixedly connected to the positioning frame 13 and the ejection plate 19, respectively.

[0034] When the robotic arm 10 malfunctions, the moving part of the linear movement mechanism 11 moves the robotic arm 10 to the inspection port 14. Then, the connecting bolts between the base 21 and the moving seat 12 are removed. Finally, the piston rod of the ejector cylinder 20 retracts, driving the ejector plate 19 to move. The ejector plate 19 pushes the base 21 from the slot 18 on the moving seat 12 into the slot 18 of the transfer vehicle 15, thus achieving the insertion of the base 21 into the body of the transfer vehicle 15.

[0035] After the base 21 is inserted into the body of the transfer vehicle 15, the piston rod of the positioning cylinder 16 retracts and moves out of the positioning hole 17, and the transfer vehicle 15 drives the robot arm 10 to move out for maintenance.

[0036] The above description only describes the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments.
