[0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material to cause it to separate or plastically deform, thereby obtaining the required parts. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive. Stamping production is mainly for sheet materials. Through the mold, it can perform processes such as blanking, punching, forming, drawing, trimming and extrusion.

A water pipe is arranged inside the fixing mechanism, and the water pipe runs through the base. The water pipe is arranged as a spiral pipe, and the cylinder is located inside the water pipe. Condensed water flows around the cylinder through the water pipe. By arranging the water pipe in a spiral shape, the heat generated by continuous stamping is quickly taken away, so that impurities are easily adhered to the stamping die after flushing, which may cause stamping defects of parts, and solves the problem that the overheated die cannot be flushed and cooled after continuous long-term stamping;

[0008] The base is fixedly connected to the connecting plate on the bracket through a connecting piece, the fixing mechanism is fixedly connected to the top of the base through a connecting block, the stamping mechanism is fixedly connected to the bracket through a connecting fastener, the water pipe is fixedly connected to the base, and the stamping mechanism and the fixing mechanism are located on the same vertical plane;

[0009] The punching mechanism comprises a cylinder, which is fixedly connected to the bracket, and the output end of the cylinder is fixedly connected to a fixing plate, and the bottom of the fixing plate is fixedly connected to a punch, and the punch is located in the middle of the fixing plate. The outer wall of the fixing plate is slidably connected to a round rod, and the round rod penetrates the fixing plate, and one end of the round rod close to the punch is fixedly connected to a fixing ring, and the outer wall of the fixing ring is fixedly connected to a compression spring. During the working process, the cylinder works, and then the cylinder drives the fixing plate to move downward, and the fixing plate drives the fixing ring to move downward, so that the fixing ring contacts the bottom metal sheet, and the fixing ring is squeezed and stressed, so that the compression spring is compressed and deformed, and then the cylinder drives the punch to continue to move downward, and the metal sheet is stamped to obtain a product of a desired shape, so as to avoid the punch from deflecting during stamping. At the same time, by setting the fixing ring, the annular pressing piece is pressed against the metal sheet to press and fix the metal sheet, so as to avoid the metal sheet from deflecting during the stamping process, so as to improve the stamping accuracy. The round rod penetrates the compression spring, and the compression spring is fixedly connected to the fixing plate at one end away from the fixing ring.

When working, the cylinder drives the punch to move downward so that the bottom cylinder contacts the metal plate. At this time, the cylinder is squeezed and stressed, and the cylinder slides upward inside the through opening, so that the spring plate is compressed by force, thereby The middle part of the spring plate bulges outward, so that the spring plate pushes the limit block to slide, so that the limit block is flush with the outer wall. After the stamping is completed, the cylinder drives the punch to move upward, so that the cylinder is away from the metal product. Under the action of the cylinder's own gravity and the elastic force of the spring plate, the cylinder and the spring plate are reset. At this time, the limit block returns to the inside of the punch, thereby reducing the contact area between the punch and the inner wall of the hole, and then reducing the friction between the punch and the inner wall of the hole, thereby reducing the wear on the hole wall and the punch.

Under the gravity of the metal sheet itself, the cylinder moves downward, and the return spring is compressed at this time. After the stamping is completed, the elasticity of the return spring is used to eject the formed metal product, so as to avoid the phenomenon that the parts are adhered to the mold and are not easy to fall off, and the parts need to be forced to be separated manually, which is easy to cause damage to the finished product, thereby reducing the yield of the metal product, so as to facilitate The stamped metal product is taken out, and the positioning plate is evenly distributed with the reset spring as the center.

The top of the round table is fixedly connected to a supporting rod. A round hole is opened in the middle of the cylinder, and the supporting rod is located inside the round hole. During operation, the cylinder drives the punch to move downward to punch the metal sheet. The elastic properties of the reset spring are utilized to make the cylinder fit tightly against the metal sheet and play a buffering role, thereby reducing the impact caused by rapid stamping and extending the service life of the equipment. At the same time, by setting the round table, when the punch continues to move downward, the stamping force is prevented from being greater than the stiffness limit of the metal sheet, resulting in damage to the metal sheet, thereby playing a limiting role.

[0017] 2. The stamping machine for processing metal packaging containers utilizes condensed water to flow around the cylinder through a water pipe. By setting the water pipe in a spiral shape, the heat generated by continuous stamping is quickly taken away, thereby preventing impurities from easily adhering to the stamping die after flushing.

[0018] 3. The stamping machine used for processing metal packaging containers uses a cylinder to move away from the metal product. Under the action of the cylinder's own gravity and the elastic force of the spring plate, the cylinder and the spring plate are reset.
