Description

Technical Field

[0001] This utility model relates to the field of servo hydraulic press technology, and in particular to a novel multi-station servo hydraulic press. Background Technology

[0002] When stamping and stretching an object to form the surface contour of a reference mold, a new type of multi-station servo hydraulic press is often used. This advanced industrial equipment is primarily used in metal forming, stamping, and extrusion manufacturing processes. This equipment combines the advantages of servo motors and hydraulic systems, enabling efficient and precise processing.

[0003] Multi-station servo hydraulic presses are typically composed of a stamping mechanism, a load-bearing mechanism, and a buffer assembly. When in use, the stamping mechanism uses the pressure generated by the hydraulic cylinder to push the punch to apply force to the workpiece, completing the forming or cutting operation. The load-bearing mechanism ensures the stability of the workpiece during stamping, and the buffer assembly can absorb impact and vibration when the stamping force is applied to the workpiece.

[0004] However, in practice, multi-station servo hydraulic presses often neglect the effective handling of workpieces after processing, especially after stamping. The workpiece may stick to the mold and fail to eject smoothly, which not only affects the efficiency of subsequent processing but also causes quality problems of the workpiece. Therefore, a new type of multi-station servo hydraulic press is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel multi-station servo hydraulic press, which aims to improve the problem that some existing devices cannot eject objects after stamping, resulting in reduced work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel multi-station servo hydraulic press includes a base, a stamping mechanism on the top of the base, an upper compression ring fixedly connected to the bottom of the stamping mechanism, a processing mechanism on the top of the base, multiple alignment grooves on the top of the base, two support columns fixedly connected to the bottom of the stamping mechanism, a clamping mechanism on the outside of the two support columns, and a bearing mechanism on the top of the base.

[0008] The processing mechanism includes a lower compression ring, the outer surface of which is located on the top of the base. The outer surface of the lower compression ring is in contact with the outer surface of the upper compression ring. A plurality of buffer components for buffering are fixedly connected to the bottom of the lower compression ring. A plurality of connecting blocks are fixedly connected to the bottom of the lower compression ring. Rotating components for rotation are rotatably connected to the outer surface of the plurality of connecting blocks. An inclined plate is fixedly connected to the outer surface of the rotating components. A top plate is fixedly connected to the outer surface of the inclined plate. The outer surfaces of the plurality of connecting blocks are respectively located on adjacent sides of the plurality of buffer components.

[0009] As a further description of the above technical solution:

[0010] The buffer assembly includes multiple movable columns, the exterior of which is located at the bottom of the lower compression ring, and buffer springs are respectively sleeved on the exterior of the multiple movable columns. The exterior of the multiple lower compression rings is slidably connected to the top of the base.

[0011] As a further description of the above technical solution:

[0012] The rotating assembly includes multiple rotating columns, which are externally rotatably connected between the connecting block and the inclined plate. Limiting rings are fixedly connected to both sides of the external surfaces of each rotating column.

[0013] As a further description of the above technical solution:

[0014] The stamping mechanism includes a support plate, the outside of which is on the top of the base. A hydraulic cylinder is fixedly connected to the top of the support plate, a connecting plate is fixedly connected to the bottom of the hydraulic cylinder, and multiple connecting columns are fixedly connected to the bottom of the connecting plate. The outside of the multiple connecting columns is fixedly connected to the top of the upper compression ring.

[0015] As a further description of the above technical solution:

[0016] The clamping mechanism includes multiple fixing plates, which are externally fixedly connected to the outside of the two pillars. A torsion column is rotatably connected to the bottom of the multiple fixing plates. A folding plate is fixedly connected to the outside of the torsion column.

[0018] The bearing mechanism includes two fixed rings, the two fixed rings are fixedly connected to the top of the base, the top of the two fixed rings are fixedly connected to a limit block, and a support column is slidably connected to the outside of the limit block;

[0019] As a further description of the above technical solution:

[0020] The cone-shaped sliding mechanism allows the object to slide outside the force-bearing block. Combined with the torsion column, this allows multiple clamping blocks to be brought together. Furthermore, the combination with the bearing mechanism enables the object to be compressed to a uniform height.

[0021] As a further description of the above technical solution:

[0022] The rotating assembly can drive the inclined plate to adjust the angle between the inclined plate and the top plate. At the same time, the bottom of the connecting block is connected to an extension plate, which allows it to slide into the alignment groove for alignment.

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.

[0033] Reference Figures 2 to 3 This utility model provides an embodiment of a novel multi-station servo hydraulic press, comprising a base 1, wherein a processing table is fixedly connected to the center of the top of the base 1 for placing molds, a stamping mechanism is provided on the top of the base 1, the stamping mechanism includes a support plate 2, the outside of the support plate 2 is on the top of the base 1, and a hydraulic cylinder 3 is fixedly connected to the top of the support plate 2, the support plate 2 serves to support the hydraulic cylinder 3, the hydraulic cylinder 3 is responsible for providing the power required for stamping, and a connecting plate 4 is fixedly connected to the bottom of the hydraulic cylinder 3, the function of which is to transmit the power generated by the hydraulic cylinder 3, and the bottom of the connecting plate 4 is fixedly connected to the bottom of the hydraulic cylinder 3. The fixed connection has multiple connecting posts 5, which are used to transmit the power of the connecting plate 4 to the upper compression ring 6. The external of the multiple connecting posts 5 is fixedly connected to the top of the upper compression ring 6. The bottom of the stamping mechanism is fixedly connected to the upper compression ring 6, which facilitates pressing the external of the object according to the surface contour of the mold. The top of the base 1 is provided with a processing mechanism. The top of the base 1 is provided with multiple alignment grooves 15. The bottom of the stamping mechanism is fixedly connected with two pillars 16, which provide a good support environment. The external of the two pillars 16 is provided with a clamping mechanism. The top of the base 1 is provided with a bearing mechanism.

[0034] The processing mechanism includes a lower compression ring 9, which closely cooperates with an upper compression ring 6 to assist in workpiece processing. The outer surface of the lower compression ring 9 is on the top of the base 1, and the outer surface of the lower compression ring 9 is in close contact with the outer surface of the upper compression ring 6. Multiple buffer components for cushioning are fixedly connected to the bottom of the lower compression ring 9. Each buffer component includes multiple movable columns 7, the outer surface of which is located at the bottom of the lower compression ring 9. Each movable column 7 is fitted with a buffer spring 8. The combination of the movable columns 7 and the buffer springs 8 is used to absorb vibration and impact loads during processing, while also ensuring the integrity of the workpiece during processing. The outer surfaces of the multiple lower compression rings 9 are slidably connected to the top of the base 1. Multiple connecting blocks 10 are fixedly connected to the bottom of the lower compression rings 9 to provide good support performance. Rotating components for rotation are rotatably connected to the outer surfaces of the multiple connecting blocks 10. Each rotating component includes multiple rotating columns 10. 1. Multiple rotating columns 11 are externally rotatably connected between connecting block 10 and inclined plate 12. The rotating columns 11 can drive the rotation between connecting block 10 and inclined plate 12. Limiting rings 14 are fixedly connected to both sides of the rotating column 11 to prevent the rotating column 11 from shifting during rotation. The external of the rotating assembly is fixedly connected to the inclined plate 12, which can change the angle during the stamping process. The external of the inclined plate 12 is fixedly connected to the top plate 13. The force generated by the inclined plate 12 is transmitted to the workpiece, and the object being stamped and stretched is ejected, preventing it from sticking to the outer surface of the mold and being difficult to remove. The external of multiple connecting blocks 10 is located on the adjacent side of multiple buffer assemblies. The rotating assembly can drive the inclined plate 12 and the top plate 13 to adjust the angle. At the same time, the bottom of the connecting block 10 is connected to an extension plate, which slides into the alignment groove 15 for alignment.

[0035] Reference Figure 1 and Figure 4The clamping mechanism includes multiple fixed plates 17 with sufficient strength. The fixed plates 17 are externally fixedly connected to the outside of the two pillars 16. The torsion column 20 is externally fixedly connected to a folded plate 18, which is bent in shape to facilitate good fit during processing. The bottom of the multiple fixed plates 17 is rotatably connected to the torsion column 20, which functions to achieve angle adjustment and prevent the folded plate 18 from shifting left or right. The pillars 16 are externally slidably connected to a cone 21. The top of the folded plate 18 is fixedly connected to a force-bearing block 19. By sliding the cone 21, the folded plate 18 connected to the force-bearing block 19 can be brought closer together at its bottom under the action of the torsion column 20. The bottom of the folding plate 18 is fixedly connected to a clamping block 22, which can fix the object. The bearing mechanism includes two fixing rings 23. The two fixing rings 23 are fixedly connected to the top of the base 1. The top of the two fixing rings 23 is fixedly connected to a limiting block 24. The limiting block 24 is slidably connected to a support column 25. The limiting block 24 can prevent the support column from having excessive sliding displacement. The cone 21 can slide outside the force block 19 through the cone-shaped sliding. At the same time, it is used in conjunction with the torsion column 20 to make the multiple clamping blocks 22 come into contact with each other. At the same time, the combination with the bearing mechanism can compress the height of the object to be consistent.

[0036] Working Principle: First, the workpiece is placed on the processing table, and the hydraulic cylinder 3 starts working, providing the power required for stamping. The power of the hydraulic cylinder 3 is transmitted through the connecting plate 4, and the lower part of the connecting plate 4 is connected to multiple connecting columns 5. These connecting columns 5 transmit the power to the upper compression ring 6, ensuring that the stamping force is evenly applied to the outside of the workpiece and pressed against the surface contour of the mold. During processing, the upper compression ring 6 and the lower compression ring 9 fit tightly together. The lower compression ring 9 is outside the base 1, and when it is in close contact with the outside of the upper compression ring 6, the combination of the movable column 7 and the buffer spring 8 effectively absorbs the vibration and impact load during processing, maintaining the integrity of the workpiece and the processing accuracy. During the stamping process, the connecting block 10 provides good stability under the support of the support column 16. The bottom of the connecting block 10 is connected to the rotating assembly, and the rotating column 11 changes angle through the rotation between the connecting block 10 and the inclined plate 12, so that the top plate 13 above can accurately transmit the pressure to the workpiece. The pressure of the top plate 13 helps to effectively push the workpiece out of the mold, avoiding difficulties in removal caused by adhesion.

[0037] When the blank object is processed, it is first placed on top of 25, and multiple fixing plates 17 initially form a stable frame under the support of the pillar 16. At the start of the clamping process, the torsion column 20 allows the fixing plates 17 to be angled, ensuring that each clamping block 22 fits more closely when clamping the workpiece. As the angle is adjusted, the cone 21, which is slidably connected to the outside of the pillar 16, can move smoothly under the action of the force block 19, causing the bottom of the folding plate 18 to gradually move closer to the center workpiece. When the cone 21 slides to the outside of the force block 19, the folding plate 18, guided by the torsion column 20, effectively controls the movement of the clamping blocks 22, making them accurately clamp the workpiece. At this time, the clamping blocks 22, through the fixed connection below them, firmly fix the position of the workpiece, preventing it from sliding or deforming during processing. At the same time, the setting of the two fixing rings 23 and the limiting block 24 of the bearing mechanism ensures that the sliding displacement of the support column 25 is effectively limited, providing stable support for the clamping process, enabling the object to be processed to the same height, and then further processed for shaping.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
