Description

Technical Field

[0001] This utility model belongs to the field of forging technology, specifically relating to a forging auxiliary device for multi-faceted forging. Background Technology

[0002] Existing multi-faceted forging technology mainly relies on traditional free forging or die forging processes, combined with manual operation or semi-automated equipment.

[0003] In existing technologies, traditional processes often rely on operators to position and clamp the workpiece face by face on a single-station forging press. This is not only inefficient, but also results in poor positioning accuracy and large deviations in the forging surface angle due to human factors, making it difficult to guarantee consistency. Although some automated equipment has introduced rotating fixtures, they generally use independent drive mechanisms to achieve clamping and rotation actions, which are complex in structure, costly, and difficult to maintain. Utility Model Content

[0004] The purpose of this utility model is to provide a forging auxiliary device for multi-faceted forging, which aims to solve the problem that although some automated equipment in the prior art introduces a rotating clamp, it generally uses an independent drive mechanism to realize the clamping and rotation actions.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A forging auxiliary device for multi-faceted forging, comprising:

[0007] Forged base plate;

[0008] A forging clamp includes forging clamping blocks, extrusion opening and closing plates, a rotary drive motor, a cross extrusion block, a forging insert sleeve, a rotary spring groove, a forging rotation spring, a rotary clamping block, a tube to be forged, and a multi-faceted forging rotating rod. Two forging clamping blocks and extrusion opening and closing plates are provided. Both forging clamping blocks are slidably connected to the upper end of a forging base plate. The two extrusion opening and closing plates are respectively fixedly connected to one side of the two forging clamping blocks. The rotary drive motor is fixedly connected to the upper end of the forging base plate, and the multi-faceted forging rotating rod is fixedly connected to the output end of the rotary drive motor. The cross extrusion block is fixedly connected to the circumferential surface of the multi-faceted forging rotating rod. The cross extrusion block slides within the two extrusion opening and closing plates and extrudes the inner walls of the two extrusion opening and closing plates. The forging insert sleeve is fixedly connected to one side end of the multi-faceted forging rotating rod. The rotating spring groove is opened on one side inner wall of the forging insert sleeve. The rotating clamping block is slidably connected within the rotating spring groove. The forging rotating spring is fixedly connected to one side inner wall of the rotating spring groove and one side end of the rotating clamping block. The tube to be forged is slidably connected within the forging insert sleeve. The tube to be forged is matched with the two forging clamping blocks.

[0009] In a preferred embodiment of this utility model, when the tube to be forged is inserted into the sleeve of the forging body, the contact surface between the rotating clamping block and the tube to be forged is an inclined surface.

[0010] As a preferred embodiment of this utility model, the upper end of the forging base plate is provided with an upper forging plate, the upper end of the upper forging plate is fixedly connected to a forging press, the output end of the forging press is fixedly connected to a forging block, and the forging block is located at the upper end of two forging clamping blocks.

[0011] In a preferred embodiment of this utility model, a closing push block is slidably connected inside the closing sleeve, the closing push block is fixedly connected to one side of the forging clamping block, and a clamping spring is fixedly connected to one side of the closing push block and one side of the inner wall of the closing sleeve.

[0012] As a preferred embodiment of this utility model, the upper end of the forging base plate is provided with a rear closing groove, and a rear closing slider is slidably connected in the rear closing groove. A multi-faceted forging rotating rod is fixedly connected to one side end of the rear closing slider and one side inner wall of the rear closing groove. The rear closing slider blocks the other side end of the two forging clamping blocks.

[0013] As a preferred embodiment of this utility model, when the cross extrusion block rotates, the two extrusion opening and closing plates are opened, and the two forging clamping blocks open, allowing the tube to be forged to rotate. After the cross extrusion block rotates ninety degrees, the two forging clamping blocks close again to clamp the tube to be forged.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this solution, the linkage between clamping and rotation is automated. The rotation drive motor drives the multi-face forging rotating rod and cross extrusion block to rotate. The mechanical cam extrusion action drives the extrusion opening and closing plate and the forging clamping block to open and close. The cycle of clamping-releasing-indexing-re-clamping can be completed without additional indexing devices or complex control systems, which greatly improves the face changing accuracy and processing efficiency, and realizes the automated operation of multi-face continuous forging.

[0016] 2. In this solution, an elastic adaptive clamping structure is adopted. When the forged tube is inserted, the inclined surface pushes the rotating clamping block to compress the rotating spring of the forging body, forming a flexible pre-tightening force. While ensuring the centering accuracy, it avoids damage or deformation of the tube surface caused by rigid clamping. It is especially suitable for tube parts with thin walls or high surface quality requirements, improving clamping safety and workpiece yield. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-4 The present invention provides the following technical solution:

[0026] A forging auxiliary device for multi-faceted forging, comprising:

[0027] Forged base plate 1;

[0028] The forging clamp includes a forging clamping block 2, a pressing opening and closing plate 3, a rotary drive motor 4, a cross pressing block 5, a forging insert sleeve 6, a rotating spring groove 7, a forging rotating spring 8, a rotating clamping block 9, a forging tube 10, and a multi-faceted forging rotating rod 20. Two forging clamping blocks 2 and pressing opening and closing plates 3 are provided. Both forging clamping blocks 2 are slidably connected to the upper end of the forging base plate 1, and the two pressing opening and closing plates 3 are respectively fixedly connected to one side end of the two forging clamping blocks 2. The rotary drive motor 4 is fixedly connected to the upper end of the forging base plate 1, and the multi-faceted forging rotating rod 20 is fixedly connected to the input of the rotary drive motor 4. At the output end, the cross extrusion block 5 is fixedly connected to the circumferential surface of the multi-faceted forging rotating rod 20. The cross extrusion block 5 slides within the two extrusion opening and closing plates 3 and extrudes the inner walls of the two extrusion opening and closing plates 3. The forging insert sleeve 6 is fixedly connected to one side end of the multi-faceted forging rotating rod 20. The rotating spring groove 7 is opened on one side inner wall of the forging insert sleeve 6. The rotating clamping block 9 is slidably connected within the rotating spring groove 7. The forging rotating spring 8 is fixedly connected to one side inner wall of the rotating spring groove 7 and one side end of the rotating clamping block 9. The forging tube 10 is slidably connected within the forging insert sleeve 6. The forging tube 10 is matched with the two forging clamping blocks 2.

[0029] In a specific embodiment of this utility model, the tube to be forged 10 is inserted into the forging insert sleeve 6, and its outer wall contacts the inclined surface of the rotating clamping block 9, pushing the rotating clamping block 9 to overcome the elastic force of the forging rotating spring 8 and slide into the rotating spring groove 7, thereby achieving initial centering and elastic clamping of the tube to be forged 10; the rotating drive motor 4 is started, and its output end drives the multi-faceted forging rotating rod 20 to rotate, and the cross extrusion block 5 fixed on it rotates synchronously. The arm of the cross extrusion block 5 enters between the two extrusion opening and closing plates 3 and squeezes their inner walls, forcing the two extrusion opening and closing plates 3 to move outward, thereby driving the two forging clamping blocks 2 to slide and separate along the forging base plate 1. At this time, the forging clamping block 2 releases the tube to be forged. Forging tube 10; As the multi-face forging rotating rod 20 continues to rotate, the cross extrusion block 5 completes a 90-degree rotation and disengages from the inner wall of the extrusion opening and closing plate 3. The extrusion opening and closing plate 3 returns to its original position under the action of the external reset mechanism, and the two forging clamping blocks 2 reclose and clamp the tube to be forged 10, realizing one rotation positioning; By precisely controlling the rotation angle and cycle of the rotation drive motor 4, the cross extrusion block 5 completes one opening and closing action of the clamping block every 90 degrees of rotation, thereby driving the tube to be forged 10 to rotate in sections and clamp alternately. In conjunction with the external forging equipment, multiple surfaces of the tube to be forged 10 are forged and formed in sequence, realizing efficient and precise multi-face continuous forging operation, improving processing efficiency and product consistency.

[0030] Please refer to the details. Figures 1-4 When the forging tube 10 is inserted into the forging insert sleeve 6, the contact surface between the rotating clamping block 9 and the forging tube 10 is inclined.

[0031] In this embodiment: when the tube to be forged 10 is inserted into the forging insert sleeve 6, its outer wall contacts the inclined surface of the rotating clamping block 9. Under the action of the thrust, the rotating clamping block 9 slides inward along the rotating spring groove 7 and compresses the rotating spring 8 of the forging body. The clamping force is adjusted adaptively by the inclined surface to realize automatic centering and elastic clamping of the tube to be forged 10, ensuring stable clamping and no damage to the surface of the tube.

[0032] Please refer to the details. Figures 1-4 The upper end of the forging base plate 1 is provided with an upper forging plate 11. The upper end of the upper forging plate 11 is fixedly connected to a forging press 12. The output end of the forging press 12 is fixedly connected to a forging block 13. The forging block 13 is located at the upper end of the two forging clamping blocks 2.

[0033] In this embodiment: an upper forging plate 11 is set on the upper end of the forging base plate 1. The upper end of the upper forging plate 11 is fixedly connected to the forging press 12. The output end of the forging press 12 is connected to the forging block 13, which is located directly above the two forging clamping blocks 2. When the tube to be forged 10 is clamped and positioned by the forging clamping blocks 2, the forging press 12 is started, driving the forging block 13 to move downward, applying high pressure forging to the surface of the tube to be forged 10 exposed between the two forging clamping blocks 2, and completing single-sided forming. Then, the drive motor 4 is rotated, and the linkage between the multi-sided forging rotating rod 20 and the cross extrusion block 5 causes the forging clamping block 2 to be released and drives the tube to be forged 10 to rotate 90 degrees and then be clamped again. The forging block 13 presses down again to forge the next side, realizing multi-sided continuous automated processing, improving forming accuracy and work efficiency.

[0034] Please refer to the details. Figures 1-4 A closed sleeve 14 is fixedly connected to the upper end of the forging base plate 1. A closed push block 15 is slidably connected inside the closed sleeve 14. The closed push block 15 is fixedly connected to one side of the forging clamping block 2. A clamping spring 16 is fixedly connected to one side of the closed push block 15 and one side of the inner wall of the closed sleeve 14.

[0035] In this embodiment: a closed sleeve 14 is fixedly connected to the upper end of the forging base plate 1. A closed push block 15 is slidably connected inside the closed sleeve 14. The closed push block 15 is fixed to one side of the forging clamping block 2. A clamping spring 16 is connected between one side of the closed push block 15 and one side of the inner wall of the closed sleeve 14. When the rotating drive motor 4 drives the multi-face forging rotating rod 20 to rotate, and the cross extrusion block 5 extrudes the opening and closing plate 3 to separate the two forging clamping blocks 2 from each other, the closed push block 15 slides synchronously inside the closed sleeve 14 and stretches or compresses the clamping spring 16 to store the reset elastic force. When the cross extrusion block 5 rotates to disengage from the inner wall of the extrusion opening and closing plate 3, the clamping spring 16 releases its elastic potential energy, pushes the closed push block 15 back to its original position, thereby driving the forging clamping block 2 to quickly reset and clamp the tube to be forged 10, ensuring stable and reliable clamping action, realizing automatic closure and precise positioning, and improving the continuity and efficiency of the multi-face forging cycle.

[0036] Please refer to the details. Figures 1-4 The upper end of the forging base plate 1 is provided with a rear closing groove 17. A rear closing slider 18 is slidably connected in the rear closing groove 17. A multi-faceted forging rotating rod 20 is fixedly connected to one side end of the rear closing slider 18 and one side inner wall of the rear closing groove 17. The rear closing slider 18 blocks the other side end of the two forging clamping blocks 2.

[0037] In this embodiment: a rear closing groove 17 is opened at the upper end of the forging base plate 1, and a rear closing slider 18 is slidably connected in the rear closing groove 17. One side end of the rear closing slider 18 is fixedly connected to one side inner wall of the rear closing groove 17 by a multi-face forging rotating rod 20. The rear closing slider 18 is located at the other side end of the two forging clamping blocks 2 and blocks them. When the tube to be forged 10 is inserted into the forging insert sleeve 6 and clamped, the rear closing slider 18 serves as the rear positioning reference surface to prevent the tube to be forged 10 from moving backward or shifting during the forging process. At the same time, when the multi-face forging rotating rod 20 is rotated under the drive of the rotation drive motor 4, it drives the rear closing slider 18 to swing synchronously in the rear closing groove 17, so that it always fits the rear end face of the forging clamping block 2 and maintains a closed state, ensuring that the clamping structure is stable and reliable, improving the axial positioning accuracy and overall structural rigidity during the forging process, and effectively avoiding processing errors caused by vibration or impact.

[0038] Please refer to the details. Figures 1-4 When the cross extrusion block 5 rotates, it opens the two extrusion opening and closing plates 3, and the two forging clamping blocks 2 open so that the tube to be forged 10 can rotate. After the cross extrusion block 5 rotates ninety degrees, the two forging clamping blocks 2 close again to clamp the tube to be forged 10.

[0039] In this embodiment: when the drive motor 4 starts and drives the multi-faceted forging rotating rod 20 to rotate, the cross extrusion block 5 fixed on it rotates synchronously. Its protruding arm gradually inserts between the two extrusion opening and closing plates 3 and extrudes their inner walls, forcing the two extrusion opening and closing plates 3 to expand outwards, thereby pushing the two forging clamping blocks 2 to slide and separate towards each other along the forging base plate 1. At this time, the clamping force on the tube to be forged 10 is released, making it free to rotate; as the cross extrusion block 5 continues to rotate to the 90-degree position, its The arm completely disengages from the inner wall of the extrusion opening and closing plate 3, and the extrusion effect disappears. Under the elastic restoring force of the clamping spring 16, the closing push block 15 drives the forging clamping block 2 to slide inward and close again, firmly clamping the tube 10 to be forged. At this time, the tube 10 to be forged has been precisely rotated 90 degrees with the multi-face forging rotating rod 20, completing the face-changing positioning of one station. Through this periodic opening and closing and clamping action, the tube 10 to be forged is exposed and stably clamped face by face, ensuring the smooth progress of multi-face continuous forging processing.

[0040] The working principle and usage process of this utility model are as follows: First, the tube to be forged 10 is inserted into the forging insert sleeve 6, and its outer wall contacts the inclined surface of the rotating clamping block 9, pushing the rotating clamping block 9 to overcome the elastic force of the rotating spring 8 of the forging body and slide into the rotating spring groove 7, thereby achieving automatic centering and elastic pre-tightening; the rotating drive motor 4 is started, and its output end drives the multi-faceted forging rotating rod 20 to rotate, and the cross extrusion block 5 fixed on it rotates synchronously. When the arm of the cross extrusion block 5 enters between the two extrusion opening and closing plates 3, it squeezes its inner wall, causing the two extrusion opening and closing plates 3 to expand outward, thereby driving the two forging clamping blocks 2 to slide and separate along the forging base plate 1, releasing the tube to be forged 10; when the cross extrusion block 5 continues to rotate to 90 degrees, it disengages from the extrusion opening and closing plates 3, and the clamping spring 16 passes through the closed... The push block 15 slides and resets within the closed sleeve 14, pushing the two forging clamping blocks 2 to close again, clamping the tube 10 to be forged, and achieving a 90-degree indexing rotation. The rear closing slider 18 swings synchronously through the multi-face forging rotating rod 20 and always blocks the rear end face of the two forging clamping blocks 2 to prevent the tube 10 to be forged from moving axially. In the clamping state, the forging press 12 drives the forging block 13 to move down, forging the surface of the tube 10 exposed between the two forging clamping blocks 2. By controlling the rotation drive motor 4 to rotate 90 degrees periodically and stop, the cycle of clamping-releasing-rotating-re-clamping is realized, so that the four sides of the tube 10 to be forged are forged in sequence, completing multi-face continuous automated processing, improving processing accuracy, stability and production efficiency.

[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
