Description

Technical Field

[0001] This utility model belongs to the technical field of cold forging, specifically, it relates to a hydraulic hammer cold forging device. Background Technology

[0002] Hydraulic hammer cold forging refers to the process of cold forging using a hydraulic hammer. Cold forging is a forging process performed without heating the blank, and is generally suitable for metals with good plasticity, such as aluminum, copper, low-carbon steel, medium-carbon steel, and low-alloy structural steel. The specific process of hydraulic hammer cold forging involves applying pressure to the metal blank using a hydraulic hammer, causing it to undergo plastic deformation at room temperature to obtain the desired shape and size. Hydraulic hammer cold forging is widely used in fields requiring high precision and small-batch production, such as machinery manufacturing, automotive parts, and aerospace components. During hydraulic hammer cold forging, multiple cold forging processes are often required to produce products of suitable dimensions and specifications. The need for semi-finished product turnover between different stages of cold forging results in a long processing cycle. Cold-forged products are also prone to getting stuck in the mold, making demolding difficult and further affecting processing efficiency.

[0003] In view of this, this utility model is hereby proposed. Utility Model Content

A guide slide 14 is provided on the side of the support box base 2 near the movable slide 6. A sliding seat 16 is slidably connected and installed in the guide slide 14. A hydraulic forging hammer 7 is installed in the sliding seat 16. An installation groove is provided on the side of the support box base 3 near the movable slide 6. A cold forging die 19 is installed in the installation groove. A demolding end plate 20 is provided at the inner end of the cold forging die 19. A demolding telescopic rod 22 is fixedly provided on the inner end face of the demolding end plate 20. The other end of the demolding telescopic rod 22 is slidably connected to a support column 21. A telescopic cavity 23 is provided in the support column 21. A spring 25 is installed in the telescopic cavity 23 to allow the demolding telescopic rod 22 to be telescopically adjusted relative to the support column 21.

[0025] The lower end of the demolding telescopic rod 22 is provided with a limiting end plate 24, which is located in the telescopic cavity 23 of the support column 21. The upper end of the spring 25 is connected to the limiting end plate 24, and the lower end of the spring 25 is connected to the bottom surface of the telescopic cavity 23. The setting of the limiting end plate 24 prevents the demolding telescopic rod 22 from detaching from the support column 21.

[0026] Multiple sets of support columns 21 and demolding telescopic rods 22 are provided. When the spring 25 is in its natural state, the demolding end plate 20 is located inside the cold forging die 19 to ensure the ejection demolding effect.

[0027] The guide groove 14 is provided with limit slots 15 on both sides, and the sliding seat 16 is provided with limit protrusions 18 on both sides. The limit protrusions 18 and the limit slots 15 match each other to ensure the stability of the sliding seat 16 during horizontal movement.

[0028] A hydraulic cylinder 5 is fixedly installed on the outside of the support box base 2. The telescopic rod of the hydraulic cylinder 5 is fixedly connected to the end face of the sliding seat 16. The number of hydraulic cylinders 5 matches the number of cold forging stations. An inspection end cover 4 is provided on the outer end face of the support box base 2 3 to facilitate the inspection and maintenance of the components inside the support box base 2 3.

[0029] Bearing seats 8 are fixedly installed on the bottom surface of the main frame 1 at both ends of the movable slide 6. A transmission screw 9 is installed between the bearing seats 8. A guide rod 10 is installed parallel above the transmission screw 9. A movable nut seat 11 is installed on the transmission screw 9 and the guide rod 10. The movable nut seat 11 can move horizontally along the transmission screw 9.

[0030] A translation motor 17 is fixedly installed on the outside of the bearing housing 8. A lifting hydraulic rod 12 is fixedly installed above the moving nut housing 11. A support block 13 is fixedly installed at the upper end of the lifting hydraulic rod 12. The support block 13 is a V-shaped block structure. The support block 13 is used for positioning support and station turnover of cold forging products.

[0031] The working principle of this utility model is as follows: During cold forging, the cold forging billet is placed on the support block 13. The support block 13 moves to a position corresponding to the cold forging mold 19 of the first station. The telescopic rod of the hydraulic cylinder 5 of the first station extends, driving the sliding seat 16 to move along the guide groove 14, thereby causing the hydraulic forging hammer 7 to move accordingly. The hydraulic forging hammer 7 pushes the billet into the cold forging mold 19 for cold forging at the first station. A demolding end plate 20 is provided at the end of the inner cavity of the cold forging mold 19. After the billet enters the cavity of the cold forging mold 19, it undergoes cold forging deformation under the action of the hydraulic forging hammer 7. The deformation is adapted to the cold forging mold 19. During the cold forging process, the demolding end is affected by external force and moves along the inner cavity of the cold forging mold 19. The demolding telescopic rod 22 moves along the telescopic cavity 23, and the spring 2... After compression and cold forging, the telescopic rod of hydraulic cylinder 5 returns to its original position, causing hydraulic forging hammer 7 to move away and no longer apply external force to the product. At this time, the compressed spring 25 returns to its original position, causing demolding end plate 20 to push the product out of the cold forging mold 19. During the cold forging process of the billet, the lifting hydraulic rod 12 retracts to avoid interference between the support block 13 and the hydraulic forging hammer 7. During the reset process of hydraulic forging hammer 7, the lifting hydraulic rod 12 resets, so that the demolded product can be effectively supported by the support block 13. The translation motor 17 drives the transmission screw 9 to work, and the moving nut seat 11 drives the support block 13 to move the product to the next station. The process of moving the support block 13 by the moving nut seat 11 can be monitored and controlled by a cylinder sensor or by other PLCs, as long as the precise displacement requirements are met. This will not be elaborated here.

[0032] Upon reaching the second workstation, repeat the above operation, and so on, to complete the cold forging process at multiple workstations. A telescopic protective cover can be installed in the moving slide 6 of the device according to the usage requirements. A protective cover can be installed on the outside of the mating structure of the transmission screw 9 and the moving nut seat 11 for protection. (Not shown in the attached figure) The hydraulic cylinder 5 and the lifting hydraulic rod 12 are both equipped with hydraulic components to ensure the realization of the function of the hydraulic cylinder 5.

[0033] The main frame 1 of this utility model is provided with multiple cold forging stations. Each station can be moved by a transmission screw 9 to drive the support block 13 to move between stations, thereby simplifying the cold forging process, realizing multi-process cold forging of products, effectively shortening the auxiliary time of process flow and clamping, and improving the efficiency of cold forging. A lifting hydraulic rod 12 is provided below the support block 13, which can drive the support block 13 to adjust its height and avoid interference during cold forging. The support box base 2 3 is provided with a demolding telescopic rod 22 and a spring 25 structure that can automatically demold. During the reset process of the spring 25, the cold-forged product is pushed out to achieve rapid demolding.
