Description

Technical Field

[0001] This application relates to the field of forging processing technology, specifically to an upsetting machine for forging. Background Technology

[0002] Forging typically requires the use of an upsetting machine during the forging process. An upsetting machine is a specialized piece of equipment in the machinery industry used to process bars. It can also be called an iron upsetting machine or a twisting machine. It mainly works by using the collision of two steel dies to remove a portion of the surface of the steel bar, thereby reducing or increasing the diameter of the steel bar. Through the principle of cold upsetting, the cross-sectional area of ​​the end of the steel bar is expanded, thereby increasing its diameter. Subsequently, threads are processed so that the effective cross-section at the threaded point is larger than that of the steel bar base material, thereby improving the joint quality and ensuring that the compressive and tensile strength of the connection is greater than that of the base material.

[0003] Application No. 202322225561.9 discloses an upsetting machine for forging, including a base, a cleaning mechanism, a collection box, an electric push rod, and a die base. By activating the electric push rod, one end of the electric push rod pushes a scraper to scrape off metal chips inside the die base multiple times. The scraped metal chips enter the collection box through the inclined surface of the discharge port. When the collection box is full of metal chips, the chuck is removed from the limiting groove, and then the metal chips inside the collection box are emptied to complete the cleaning. This facilitates rapid cleaning of the die base, prevents the accumulation of chips generated during processing from affecting the next processing, and improves cleaning efficiency.

[0004] However, in practice, it has the following drawbacks:

[0005] Although the workpiece is stamped after passing through the round hole into the mold base, the cross-sectional area of ​​the workpiece changes after stamping. At this time, it may not be able to be pulled out of the round hole, causing it to get stuck. This indicates that the bottom of the mold base lacks support during stamping, which may cause the stamped workpiece to be bent directly, changing the actual shape of the workpiece for use. Utility Model Content

[0006] The purpose of this application is to provide an upsetting machine for forging, which solves the problems mentioned in the background art. Although the workpiece is passed through the round hole into the die base and then stamped, the cross-sectional area of ​​the workpiece changes after stamping. At this time, it may not be able to be pulled out of the round hole, resulting in jamming. Furthermore, the lack of support at the bottom of the die base during stamping may cause the stamped workpiece to be bent directly, changing the actual shape of the workpiece.

[0007] To achieve the above objectives, this application provides the following technical solution: an upsetting machine for forging, comprising a base, a lower die holder, a center block, a telescopic rod, and a support block. A support frame is fixedly installed at the center of the top of the base, and an electrical distribution box is fixedly installed at the center of the top of the support frame. A hydraulic cylinder is fixedly installed at the center below the top of the support frame, and a punch head is fixedly installed at the bottom of the hydraulic cylinder. A lower die holder is fixedly connected to the center of the top of the base directly below the punch head. An upper die holder is hinged to the top edge of the lower die holder. A top groove is formed through the top of the upper die holder, and triangular openings are formed at the bottom of the right side wall of the upper die holder and the top of the right side wall of the lower die holder. The triangular openings communicate with the inner sides of the upper and lower die holders. A center block is horizontally fixedly connected to the inner side of the lower die holder.

[0008] In this technical solution, the power distribution box supplies power to the hydraulic cylinder, activating it. During the downward extension process, the stamping head can stamp the workpiece. The workpiece is placed in the triangular opening of the lower die base, and then the upper die base is closed. The workpiece is fixed by the limiting bolts and the extrusion block. The triangular opening can support workpieces of different sizes. Twisting the limiting bolts causes the extrusion block to move downward, allowing the extrusion block to limit the workpiece from above, thus keeping it fixed. This makes the process more stable and improves processing efficiency. After processing, the workpiece can be removed simply by opening the upper die base, avoiding the problem of being unable to remove the workpiece due to deformation. At the same time, the bottom of the workpiece can be supported by the support block, telescopic rod, and limiting block. Different workpieces have different sizes, and the distance from their bottom to the top surface of the center part is also different. Support blocks of different thicknesses are placed at the top center of the center block. When the length of the telescopic rod is adjusted, the limiting rod can press the support block from the edge to prevent the support block from shifting during the stamping process, improving the adaptability of the device and the stamping efficiency.

[0009] As an optional solution to the technical solution of this application, a limiting bolt is threadedly connected to the top right side of the upper mold base, and the bottom of the limiting bolt is located inside the triangular opening and is movably connected to the extrusion block.

[0010] As an optional solution to the technical solution of this application, the top two sides of the central block are provided with conical grooves, and the surfaces of the conical grooves and the triangular openings are on the same horizontal line.

[0011] As an optional solution to the technical solution of this application, a drop groove is provided through the bottom of the lower mold base on both sides of the central block.

[0012] As an optional solution to the technical solution of this application, a support block is movably placed at the top center of the central block, and two welding seats are welded to the side walls of the central block on both sides of the support block. A telescopic rod is fixedly connected to the top of the welding seat, and a limit block is fixedly connected to the top of the side wall of the telescopic rod.

[0013] As an optional solution to the technical solution of this application, the side wall of the telescopic rod is threaded with an adjusting bolt.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] 1. This application uses limiting bolts and extrusion blocks to fix the workpiece. The triangular opening can support workpieces of different sizes. Twisting the limiting bolts causes the extrusion blocks to move downwards, allowing the extrusion blocks to limit the workpiece from above, thus keeping the workpiece fixed. This makes the process more stable and improves processing efficiency. After processing, the workpiece can be removed simply by opening the upper mold base, avoiding the problem of the workpiece being unable to be removed due to deformation.

[0016] 2. This application uses a support block, a telescopic rod, and a limiting block to support the bottom of the workpiece. Different workpieces have different sizes, and the distance from their bottom to the top surface of the center workpiece is also different. By selecting support blocks of different thicknesses and placing them at the top center of the center block, and then adjusting the length of the telescopic rod, the limiting rod can press the support block from the edge to prevent the support block from shifting during the stamping process, thereby improving the adaptability of the device and the stamping efficiency.

[0025] like Figure 1 As shown, a lower die base 6 is fixedly connected to the top center of the base 1 directly below the stamping head 5. An upper die base 7 is hinged to the top edge of the lower die base 6. A top groove 701 is provided through the top of the upper die base 7. Triangular openings 8 are provided on the lower right side wall of the upper die base 7 and the upper right side wall of the lower die base 6. The triangular openings 8 are connected to the inner sides of the upper die base 7 and the lower die base 6. A center block 11 is fixedly connected to the inner side of the lower die base 6. The triangular openings 8 can conveniently support workpieces of various sizes.

[0026] like Figure 2 As shown, the top right side of the upper mold base 7 is threaded with a limiting bolt 9. The bottom of the limiting bolt 9 is located inside the triangular opening 8 and is movably connected to the extrusion block 10. The extrusion block 10 can further limit the workpiece.

[0027] like Figure 3 As shown, tapered grooves 12 are provided on both sides of the top of the center block 11, and the surface of the tapered grooves 12 and the triangular opening 8 are on the same horizontal line. The bottom of the lower mold base 6 on both sides of the center block 11 is provided with a drop groove 13. The tapered grooves 12 can increase the support area for the workpiece, and the drop grooves 13 can facilitate the discharge of debris.

[0028] like Figure 4As shown, a support block 14 is movably placed at the top center of the center block 11. Two welding seats 15 are welded to the side walls of the center block 11 on both sides of the support block 14. A telescopic rod 16 is fixedly connected to the top of the welding seat 15. A limit block 17 is fixedly connected to the top of the side wall of the telescopic rod 16. An adjusting bolt 161 is threadedly connected to the side wall of the telescopic rod 16.

This makes the processing more stable and improves the processing efficiency. Furthermore, after processing, the workpiece can be removed simply by opening the upper mold base 7, avoiding the problem of being unable to remove the workpiece due to deformation. At the same time, the bottom of the workpiece can be supported by the support block 14, the telescopic rod 16, and the limiting block 17.
