Description

Technical Field

[0001] This invention belongs to the field of metal sheet stamping technology, and specifically relates to a metal sheet stamping forming device. Background Technology

[0002] Stamping refers to the processing and forming method that uses a press and mold to apply external force to sheet metal, strip, tube and profile, so as to cause plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size. When stamping metal sheets, corresponding stamping equipment is used. Traditional stamping forming devices include structures such as support rods, top plates, upper dies, lower dies, lifting plates, fixed frames, extrusion plates, ejector rods, springs, push plates, bottom plates, flow dividers, and protective plates. The advantage of this stamping forming device is that it facilitates the cleaning of debris inside the lower die. However, in the process of using traditional stamping forming equipment, the operator needs to repeatedly place the metal sheet to be processed on the lower mold, and the workpiece in the lower mold needs to be demolded and removed before placing the metal sheet to be processed. Therefore, the time available for placing the metal sheet each time is relatively short, making it difficult for the user to place the metal sheet to be processed accurately. This results in a high defect rate in the stamping forming equipment and unsatisfactory processing efficiency, which urgently needs to be improved. Summary of the Invention

[0027] The working principle and usage process of this invention: When in use, two metal plates to be processed (hereinafter referred to as workpieces) are inserted into the two ends of the deformable support 83 through the limiting insertion groove 836 respectively. At this time, the workpieces are pressed and reinforced by the limiting reinforcement ball 843 to prevent the workpieces from sliding along the limiting insertion groove 836. Then, the rotatable mounting tube 834 is driven to rotate by the variable speed power output component 831, so that one of the workpieces is located above the deformable pressing mechanism 3 and is in a horizontal position. Then, the second limit position changer 34 is extended to move the adjustable lower die 32 upward. At the same time, the fourth limit position changer 62 is extended to move the adjustable upper die 60 downward. Thus, the workpiece in the workpiece to be processed is stamped by the movement of the adjustable lower die 32 and the adjustable upper die 60 to form the workpiece. After the stamping is completed, the second limit position changer 34 is contracted to move the adjustable lower die 32 downward to reset. The fourth limit position changer 62 is contracted to move the adjustable upper die 60 upward to reset. At this time, the adjustable lower die 32 and the adjustable upper die 60 are completely separated from the workpiece. Then, the variable speed power output component 831 drives the rotatable mounting tube 834 to rotate 180°. During this process, the processed workpiece automatically slides down under the action of gravity while rotating downwards (if it does not slide down by itself, the user can pull it out). Another workpiece to be processed rotates upwards to achieve high-precision automated feeding. Thus, the rotation of the rotatable mounting tube 834 achieves fast and automated feeding of workpieces. Then, the device continues to execute the stamping program on the fed workpiece. During the stamping program of the automatically fed workpiece, the user can replenish the empty workpiece position on the deformable support 83, so that the user has enough time to feed the workpiece without rushing the feeding and improving the feeding accuracy of the device. Thus, through the cooperation of multiple structures, users can place the metal sheet to be processed while the stamping forming device is processing the metal sheet. Subsequently, the feeding structure automatically performs high-precision feeding through rotation, thereby improving the processing efficiency of the stamping forming device and reducing the defect rate. Secondly, after stamping is completed, the invention can control the adjustable upper pressure die 32 and the adjustable lower pressure die 60 to fully disengage from the metal sheet, thereby facilitating unloading by the user. In addition, the invention has a simple structure, is easy to use, and has low cost, making it worthy of promotion and use.

One end of each component is fixedly connected to the first limiting and supporting metal tube, and the other end is fixedly connected to the second limiting and supporting metal plate. A fourth limiting and supporting metal plate is arranged below the first limiting and supporting metal tube, and is fixedly connected to and slidably connected to the first limiting and supporting metal tube. An adjustable pressing die is arranged above the first limiting and supporting metal tube. Several second limiting position changing components are arranged at both ends of the fourth limiting and supporting metal plate to adjust the height of the adjustable pressing die.

8. The metal sheet stamping and forming apparatus according to claim 7, characterized in that: The deformable pressing mechanism includes a second limiting and lifting metal tube. Several third limiting position changing components are arranged on the side of the second limiting and lifting metal tube facing the second limiting and lifting metal plate. These third limiting position changing components are spaced apart at both ends of the second limiting and lifting metal tube. An adjustable pressing mold corresponding to the adjustable lower pressing mold is arranged below the second limiting and lifting metal tube. A fifth limiting and lifting metal plate is fixedly connected to the top of the second limiting and lifting metal tube. Several fourth limiting position changing components for height adjustment of the adjustable pressing mold are arranged at both ends of the lower surface of the fifth limiting and lifting metal plate. The top of the fourth limiting position changing component is fixedly connected to the fifth limiting and lifting metal plate, and the bottom of the fourth limiting position changing component is fixedly connected to the adjustable pressing mold.

9. The metal sheet stamping and forming apparatus according to any one of claims 1-8, characterized in that: The second limiting and lifting metal plate is provided with a detachable sound-absorbing plate for noise reduction on the side facing the deformable feeding mechanism. The third limiting and lifting metal plate is provided with several deformable reinforcing plates for shock absorption and anti-slip reinforcement of the first limiting and lifting metal plate. The several deformable reinforcing plates are spaced apart at both ends of the lower surface of the first limiting and lifting metal plate. The first limiting and lifting metal plate is fixedly connected to the deformable reinforcing plates.
