Description

Technical Field

[0001] The utility model relates to the technical field of forging stamping, in particular to a forging stamping fixing device. Background Technique

[0002] A forging is a processing technology in which metal materials are hammered, pressed or extruded under heating conditions to change them into the required shapes and structures. It is usually applied in fields such as automobiles, aerospace, ships, rail transit, etc. When stamping a forging, a fixing device is needed to fix the position of the workpiece to prevent its position from shifting during the processing.

[0003] A forging stamping part fixing device with the publication number of CN216757895U has a base as the main body. Support rods are fixed at the four corners of the top side of the base. The top ends of the support rods are fixed with a top plate. A stamping cylinder is installed on the top side of the top plate. A fixing plate is fixed on the side of the base. A motor is fixed on the top side of the fixing plate. The output end of the motor is fixed with a shaft rod. The two ends of the shaft rod are respectively provided with a first external thread and a second external thread. A first internal thread ring is rotatably installed on the first external thread and the second external thread. A sliding rod is fixed on the top side of the first internal thread ring. A first sliding hole is opened on the top side of the base. A connecting plate is arranged on the side of the sliding rod. The bottom end of the connecting plate is fixed with a pressing plate. A lower die base is fixed on the top end of the base. This fixing device clamps and fixes forgings with different shapes and models by adjusting the distance between the two sliding rods, so that the stamping equipment can process stamping parts with different model sizes, making the equipment have a wider application range.

[0004] There are still problems in the above-mentioned forging stamping part fixing device. During the use of this fixing device, only the two ends of the top side of the workpiece are clamped and fixed. During stamping processing, the stressed position of the workpiece is likely to shift to the unconstrained sides, resulting in a decline in the stamping processing quality of the stamping equipment. Therefore, a forging stamping fixing device is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, during the use of the fixing devices on the market, only the two ends of the top side of the workpiece are clamped and fixed. During stamping processing, the stressed position of the workpiece is likely to shift to the unconstrained sides, resulting in a decline in the stamping processing quality of the stamping equipment. The utility model proposes a forging stamping fixing device.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A forging stamping fixing device of the utility model includes a processing table; a clamping mechanism is arranged inside the processing table, an auxiliary mechanism is arranged on the side of the clamping mechanism, a rotating mechanism is arranged on the top side of the processing table, and a cylinder body is rotatably installed inside the processing table.

[0007] Preferably, the clamping mechanism includes a cylinder body. Inside the cylinder body, mounting frames are arranged staggeredly, and the two side mounting frames are perpendicular to each other. At the center position inside the bottom mounting frame, a first double-headed motor is fixed. At the output end of the first double-headed motor, a first lead screw is fixed. At both ends of the first lead screw, first sliding seats are installed. On the top side of the first sliding seat, a round rod is fixed. At the center position inside the top mounting frame, a second double-headed motor is fixed. At the output end of the second double-headed motor, a second lead screw is fixed. At both ends of the second lead screw, second sliding seats are installed. On the top side of the second sliding seat, a support rod is fixed. The first sliding seat and the second sliding seat are slidably installed inside the mounting frame. On the surface of the cylinder body, a limiting groove is formed, and the round rod and the support rod are slidably installed inside the limiting groove. By driving the lead screw to rotate through the motor, since the thread directions of the lead screws at both ends are opposite, the round rods and the support rods on both sides are driven to move towards each other, clamping and fixing the side surface of the forging to prevent it from shifting under force during the processing.

[0008] Preferably, the auxiliary mechanism includes a mounting frame. At both ends of the side surface of the mounting frame, support plates are symmetrically fixed. On the top side of the support plate, a hydraulic cylinder is fixed. Inside the hydraulic cylinder, a hydraulic rod is slidably installed. The hydraulic rod slidably penetrates through the support plate. At both ends of the bottom mounting frame, connecting plates are symmetrically fixed. The bottom end of the hydraulic rod is fixedly connected to the connecting plate. At the top ends of the round rod and the support rod, a clamping plate is fixed. At a corner of the top side of the processing table, a servo motor is fixedly installed. By driving the clamping plates on the top side and the bottom side to clamp the top side and the bottom side surfaces of the forging respectively through the hydraulic cylinder, the forging is limited in the vertical direction, making it less likely to shift in position during the processing.

[0009] Preferably, the rotating mechanism includes a servo motor. The output end of the servo motor passes through the processing table and is fixed with a small gear, and the small gear is rotationally connected to the cylinder body. On the circumferential surface of the top side of the cylinder body, a large gear is fixed. The small gear meshes with the large gear. At one end of the top side of the processing table, a support frame is fixed. At the bottom end inside the support frame, a stamping equipment body is arranged. At the center position of the top side of the processing table, a mold body is arranged. By driving the cylinder body to rotate through the gear cooperation, before the processing, the forging can be rotated to the required processing position, making the equipment more convenient to use.

[0010] The advantages of the present utility model are as follows:

[0011] 1. Through the structural design of a forging stamping fixing device, the utility model solves the problem that the existing fixing device is prone to force offset after fixing the workpiece. By setting a clamping mechanism, the forging is placed at the processing position on the top side of the processing table. The first double-headed motor and the second double-headed motor are controlled to drive the first lead screw and the second lead screw to rotate respectively. Since the thread directions at both ends of the lead screw are opposite, the first sliding seat and the second sliding seat on both sides are driven to move towards each other at one end, so that the round rods and the support rods on both sides move centrically inside the limit groove at the same time, clamping and fixing the forging, and limiting its four sides to prevent the force position from shifting during the forging processing.

[0012] 2. Through the structural design of a forging stamping fixing device, the utility model solves the problem that the existing fixing device is prone to force offset after fixing the workpiece. By setting an auxiliary mechanism, when the forging is placed at the processing position on the surface of the processing table, the forging is located on the top side of the clamping plate on the round rod. At this time, the hydraulic cylinder is controlled to contract the hydraulic rod inside it, thereby pulling the mounting frame to slide inside the cylinder body, reducing the distance between the two mounting frames on both sides. At this time, the clamping plate on the top side of the support rod contacts the top side surface of the forging, and with the cooperation of the bottom clamping plate, the forging is clamped and fixed, thereby limiting the forging in the vertical direction to prevent its position from shifting during the processing.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 As shown, a forging stamping fixing device includes a processing table 1; a clamping mechanism is arranged inside the processing table 1, an auxiliary mechanism is arranged on the side of the clamping mechanism, a rotating mechanism is arranged on the top side of the processing table 1, and a cylinder body 2 is rotatably installed inside the processing table 1;

[0022] Please refer to Figure 2As shown in the figure, the clamping mechanism includes a cylinder body 2. Inside the cylinder body 2, mounting brackets 3 are arranged in a staggered manner, and the mounting brackets 3 on both sides are perpendicular to each other. At the center position inside the bottom mounting bracket 3, a first double-headed motor 4 is fixed. The output end of the first double-headed motor 4 is fixed with a first lead screw 5. Both ends of the first lead screw 5 are provided with first sliding seats 6. The top side of the first sliding seat 6 is fixed with a round rod 7. At the center position inside the top mounting bracket 3, a second double-headed motor 8 is fixed. The output end of the second double-headed motor 8 is fixed with a second lead screw 9. Both ends of the second lead screw 9 are provided with second sliding seats 10. The top side of the second sliding seat 10 is fixed with a support rod 11. The first sliding seat 6 and the second sliding seat 10 are slidably mounted inside the mounting bracket 3. The surface of the cylinder body 2 is provided with a limit groove 201, and the round rod 7 and the support rod 11 are slidably mounted inside the limit groove 201. During operation, when encountering the problem that the workpiece is prone to force deviation during stamping processing by the existing fixing device, through the structure of the clamping mechanism, the forging is placed at the processing position on the top side of the processing table 1. Control the first double-headed motor 4 and the second double-headed motor 8 to drive the first lead screw 5 and the second lead screw 9 to rotate respectively. Since the thread directions at both ends of the lead screw are opposite, the first sliding seats 6 and the second sliding seats 10 on both sides are driven to move towards each other, so that the round rods 7 and the support rods 11 on both sides move towards the center simultaneously inside the limit groove 201, clamping and fixing the forging and limiting its four sides to prevent the force position of the forging from deviating during the processing process.

[0023] Please refer to Figure 3 As shown in the figure, the auxiliary mechanism includes a mounting bracket 3. At both ends of the side of the mounting bracket 3, support plates 13 are symmetrically fixed. The top side of the support plate 13 is fixed with a hydraulic cylinder 15. Inside the hydraulic cylinder 15, a hydraulic rod 16 is slidably mounted. The hydraulic rod 16 slidably penetrates inside the support plate 13. At both ends of the bottom mounting bracket 3, connecting plates 14 are symmetrically fixed. The bottom end of the hydraulic rod 16 is fixedly connected to the connecting plate 14. The top ends of the round rod 7 and the support rod 11 are fixed with clamping plates 12. A servo motor 17 is fixedly installed at a corner of the top side of the processing table 1. During operation, when encountering the problem that the workpiece is prone to large force and deviation during stamping processing, through the structure of the auxiliary mechanism, when the forging is placed at the processing position on the surface of the processing table 1, the forging is located on the top side of the clamping plate 12 on the round rod 7. At this time, control the hydraulic cylinder 15 to contract the hydraulic rod 16 inside it, thereby pulling the mounting bracket 3 to slide inside the cylinder body 2, reducing the distance between the mounting brackets 3 on both sides. At this time, the clamping plate 12 on the top side of the support rod 11 contacts the top surface of the forging, and thus, in cooperation with the bottom clamping plate 12, the forging is clamped and fixed, thereby limiting the forging in the vertical direction to prevent its position from deviating during the processing process.

[0024] Please refer to Figure 4As shown, the rotating mechanism includes a servo motor 17. The output end of the servo motor 17 passes through the processing table 1 and is fixed with a small gear 18, and the small gear 18 is rotationally connected to the cylinder body 2. A large gear 19 is fixed on the circumferential surface of the top side of the cylinder body 2. The small gear 18 meshes with the large gear 19. One end of the top side of the processing table 1 is fixed with a support frame 20, and a stamping equipment body 21 is arranged at the inner bottom end of the support frame 20. A mold body 22 is arranged at the central position of the top side of the processing table 1. During operation, when encountering the problem that the workpiece needs to be disassembled and refixed when changing the processing position, resulting in a reduction in processing efficiency, through the structure of the rotating mechanism, the servo motor 17 is controlled to drive the small gear 18 at the output end to rotate. At this time, the small gear 18 drives the meshing large gear 19 to rotate, thereby driving the cylinder body 2 to rotate. At this time, the processing position of the forging inside the cylinder body 2 can be changed by rotating the mold body 22 on the top side of the cylinder body 2, thereby improving the processing efficiency of the equipment.

[0025] Please refer to Figure 5 As shown, scale grooves 23 are evenly formed on the top side of the processing table 1. During operation, when encountering the problem that the processing position of the forging cannot be accurately adjusted, through the structure of the scale grooves 23, when the cylinder body 2 is rotated, by observing the positions of the scale grooves 23 where it is located before and after rotation, the rotation angle of the workpiece can be accurately measured, so that it can be accurately adjusted to the required processing angle, making the processing accuracy of the workpiece higher.

[0026] Working principle: A forging is a processing technology in which metal materials are hammered, pressured, or extruded under heating conditions to change them into the required shape and structure. It is usually applied in fields such as automobiles, aerospace, ships, and rail transit. When performing stamping processing on forgings, a fixing device is required to fix the position of the workpiece to prevent its position from shifting during the processing. During the use of the existing fixing device, only the two ends on the top side of the workpiece are clamped and fixed. During stamping processing, the workpiece is prone to shifting to the unconstrained two sides due to the force application position, resulting in a decline in the stamping processing quality of the stamping equipment. To solve this problem, by setting a clamping mechanism and an auxiliary mechanism, the forging is placed inside the mold body 22. The first double-headed motor 4 and the second double-headed motor 8 are controlled to drive the first lead screw 5 and the second lead screw 9 to rotate respectively. Since the thread directions at both ends of the lead screw are opposite, the first sliding seats 6 and the second sliding seats 10 on both sides move towards each other at one end, causing the round rods 7 and the support rods 11 on both sides to move centrally inside the limit groove 201 at the same time, so as to clamp and fix the forging and limit its four sides. At this time, the forging is on the top side of the clamping plate 12 on the round rod 7. At this time, the hydraulic cylinder 15 is controlled to contract the hydraulic rod 16 inside it, thereby pulling the mounting frame 3 to slide inside the cylinder body 2, reducing the distance between the two mounting frames 3 on both sides. At this time, the clamping plate 12 on the top side of the support rod 11 contacts the top surface of the forging, so as to clamp and fix the forging in cooperation with the clamping plate 12 on the bottom side, thereby limiting the forging in the vertical direction. Finally, the servo motor 17 is controlled to drive the pinion 18 at the output end to rotate. At this time, the pinion 18 drives the meshing large gear 19 to rotate, thereby driving the cylinder body 2 to rotate. At this time, the processing position of the forging inside it can be changed by rotating the mold body 22 on the top side of the cylinder body 2. After that, the stamping equipment body 21 is controlled to perform stamping processing on the forging. After the processing is completed, the double-headed motor is controlled to reverse at the same time, and the forging can be removed, solving the problem that the existing fixing device is prone to force offset after fixing the workpiece.
