Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to an automatic material feeding and unloading stamping die. Background Technology

[0002] Stamping dies are special process equipment used for cold stamping, commonly known as cold stamping dies. They are a pressure processing method that uses dies mounted on a press to apply pressure to materials, causing them to separate or plastically deform, thereby obtaining the desired parts. Stamping dies are widely used in the processing of metal or non-metal sheets and can produce parts of various shapes and sizes, such as automotive parts, electrical parts, and furniture parts.

[0003] For example, the Chinese Utility Model Application provides "A Stamping Die with a Quickly Replaceable Stamping Die Head", Publication No.: CN221773299U. This application includes a receiving base and an installation assembly. Support columns are installed on both sides of the upper end of the receiving base. The installation assembly is distributed on the upper end of the receiving base, and the installation assembly includes a mold body, an installation frame, a movable rod, a return spring, an installation groove, a movable die head, an installation slider, and a limiting groove. The upper end of the mold body is provided with an installation frame on both sides, and a movable rod is connected inside the installation frame. A return spring is added inside the installation frame outside the movable rod. An installation groove is opened at the lower end of the mold body. This stamping die with a quickly replaceable stamping die head avoids the problem of cumbersome and time-consuming installation and replacement of the stamping die head, which is caused by the use of traditional fastening bolts to fix the die head to the mold in most stamping dies, through the setting of the installation assembly, thus improving the overall practicality of the stamping die.

[0004] While the stamping dies described above facilitate the replacement of the stamping die head, the lack of a quick demolding and automatic unloading structure means that personnel often need to manually remove the stamped workpiece during use. Furthermore, since personnel must move between the lower die and the movable die head during the unloading process, they are prone to hand injuries due to human error or malfunction, thus affecting the safety of the overall processing operation and making it unsuitable for use by personnel.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a collection box 4 is placed on the left end of the top of the outer surface of the processing table 1. A guide platform 5 is fixedly connected to the left end of the top of the outer surface of the processing table 1 and to the right of the collection box 4.

The top of the support springs 22 is fixedly connected to the top of the inner cavity of the processing table 1. A stabilizing frame 15 is fixedly connected to the right end of the top of the inner cavity of the processing table 1. The lower end of the stabilizing frame 15 is connected to a bearing. The left end of the rotating shaft 16 is movably connected to the stabilizer 15. The right side of the stabilizer 15 is fixedly connected to the upper right side of the inner cavity of the processing table 1. There are two support crossbars 18. The surface of the moving guide rod 11 is movably connected to the right end of the support crossbar 18. The left end of the bottom of the inner cavity of the processing table 1 and the left side of the rotating rod 14 is fixedly connected to the support frame 13. The right end of the top of the support frame 13 is movably connected to the upper end of the rotating rod 14 through a bearing. The two ends of the top of the fixed frame 8 are movably connected to the positioning rod 7. The bottom of the positioning rod 7 is fixedly installed on the top of the upper mold 9. The front surface of the processing table 1 is fixedly installed with a maintenance plate by bolts. Rubber supports are fixedly connected to the four sides of the bottom of the outer surface of the processing table 1.

[0028] In this technical solution, the collection box 4 and the guide platform 5 are used to guide and collect the workpieces fed from the top of the lower mold 3, facilitating subsequent centralized handling by personnel. The fixed plate 20, guide slide rod 21, and support spring 22 effectively guide the upright 19, preventing it from tilting during movement. Simultaneously, as the upright 19 moves upward, the fixed plate 20 compresses the support spring 22, generating tension. This tension allows the support spring 22 to push the fixed plate during the subsequent rotation and reset of the guide turntable 23. 20 and upright 19 move downwards to reset. The stabilizing frame 15 and supporting crossbar 18 support the rotating shaft 16 and moving guide rod 11 respectively, preventing them from tilting due to force.

The positioning rod 7 guides the upper mold 9, preventing it from tilting or shifting during movement. The inspection plate facilitates maintenance of the interior of the processing table 1.

[0029] The working principle of this utility model is as follows: By controlling the extension of the hydraulic cylinder 6, the upper mold 9 can be pushed downwards, causing the upper mold 9 to press the material placed on the top of the lower mold 3 into the forming cavity, thereby achieving the effect of stamping and forming the material. Subsequently, by controlling the retraction of the hydraulic cylinder 6, the upper mold 9 is driven back to its original position. At the same time, by starting the drive motor 2, the rotating shaft 16, the spiral guide groove 17, and the bevel gear 24 are driven to rotate. The rotation of the bevel gear 24 drives the gear ring 25, the guide turntable 23, and the rotating rod 14 to rotate along the bearing on the worktable, guiding... While the turntable 23 rotates, it can push the upright 19 and the top plate 12 upward through the inclined plane. Under the action of the movement, the top plate 12 can push the workpiece stamped inside the lower mold 3 upward, thereby achieving the effect of quickly demolding the workpiece. At the same time, under the continuous rotation of the spiral guide groove 17, it can drive the moving guide rod 11 and the push plate 10 to move to the left. Under the action of the movement, the push plate 10 can push the workpiece pushed out of the top of the top plate 12 to the left, so that the workpiece can be separated from the top of the lower mold 3, thereby achieving the effect of unloading the formed workpiece.
