[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels.

[0018] Example: like Figure 1 - Figure 6As shown, this embodiment proposes a stamping die for a rolled part 3, comprising a base 1, a die body 2, a punch assembly and two punch assemblies, wherein the die body 2 is arranged on the upper surface of the base 1, the rolled part 3 to be stamped is placed in the die body 2, the punch assemblies are arranged on both sides of the die body 2, and a stamping area for punching holes at both ends of the rolled part 3 is formed between the two punch assemblies, and the punch assembly is arranged vertically above the rolled part 3; This is achieved by placing the trimming and punching blade 11 and the forming on the same mold body 2. The mold uses a punch press to connect the first telescopic cylinder 5 to the punch press. The start time of the first telescopic cylinder 5 is set at the upper limit height position of the mold opening. After the roller pressed part 3 is placed in the mold body 2, the punch button is started. The mold is punched to the lower mold closing position and the cylinder pulls the slider 9 to separate the slider 9 from the product. The production rhythm can be guaranteed without adding the stamping process. It can be achieved on the existing mold, is easy to use, and can ensure that the product size is qualified and stable.

[0019] The stamping assembly includes a fixing seat 4 arranged on both sides of the mold body 2, and a first telescopic cylinder 5 is arranged on the fixing seat 4. The first telescopic cylinder 5 is fixed by screws 6. The first telescopic cylinder 5 is fixed by screws 6 to improve the stability of the first telescopic cylinder 5 when in use. The fixing seat 4 is provided with an abutment plate extending upward away from the output end of the first telescopic cylinder 5, and the abutment plate abuts against the tail of the first telescopic cylinder 5, thereby further improving the stability of the first telescopic cylinder 5 when working. Fixing plates 7 are arranged on both sides of the mold body 2, and pressure blocks 8 are fixed on both sides of the upper surface of the fixing plate 7 by bolts, and an independent cavity is reserved between the two pressure blocks 8. The independent cavity formed by the two pressure blocks 8 facilitates the movement of the trimming punching knife 11 in the cavity to stamp the rolled part 3. The opposite sides of the two pressing blocks 8 are both provided with slide grooves inwardly, and a slider 9 is arranged in the cavity. The two sides of the slider 9 extend into the slide groove and slide along the length direction of the slide groove. The trimming punching edge 11 and the forming block are installed on the fixed plate 7 and fixed in position with screws 6 and dowel pins on the pressing blocks 8 on both sides. The first telescopic cylinder 5 is connected to the punching edge through the connecting block 10, so that the first telescopic cylinder 5 can push the slider 9 forward smoothly, wherein the connecting block 10 is a hook nail joint structure. The power output end of the telescopic cylinder is connected to a trimming punching blade 11 through a connecting block 10. The trimming punching blade 11 is pushed by the telescopic cylinder to abut against the rolling part 3. After the parts are installed, the cylinder structure, the trimming punching blade 11 and the forming block structure are installed on the lower mold of the mold body 2. After installation, the first telescopic cylinder 5 wire is connected to the punch control valve and the punch is controlled to operate the first cylinder. The punch is started and the first telescopic cylinder 5 pushes the trimming punching blade 11 forward to insert it into the product. When the punch reaches the bottom dead point of the closed mold, the first telescopic cylinder 5 pulls the slider 9 to push the product out. The structure of the first telescopic cylinder 5 ensures that the mold can be formed in place first and then punched and trimmed, thereby reducing the stamping mold process.

[0020] Furthermore, the punch assembly includes a guide rod 12 disposed on the base 1, and the guide rod 12 is connected to a support frame 13 at one end away from the base 1, and a guide sleeve is sleeved on the outer side of the guide rod 12, and an extrusion plate 14 is installed on the outer side of the guide sleeve. A second telescopic cylinder 15 is disposed in the support frame 13, and the power output end of the second telescopic cylinder 15 is connected to the upper surface of the extrusion plate 14. As the second telescopic cylinder 15 is moved, the power output end of the second telescopic cylinder 15 pushes the extrusion plate 14, and as the guide sleeve slides along the length direction of the guide rod 12, the extrusion plate 14 is driven to move toward the rolling press and abut against the rolling part 3, thereby ensuring that the size is qualified and stable without adding the existing stamping process, and is realized on the existing mold.

[0021] A method for using a stamping die for a rolled part 3, the specific steps are as follows: S1, placing the rolled piece 3 to be punched on the surface of the mold body 2, with both ends of the rolled piece 3 facing the first telescopic cylinder 5; S2, start the second telescopic cylinder 15, the power output end of the second telescopic cylinder 15 pushes the extrusion plate 14, and as the guide sleeve slides along the length direction of the guide rod 12, the extrusion plate 14 moves toward the roller and contacts the roller 3; S3, install the first telescopic cylinder 5 on the fixing seats 4 on both sides of the mold body 2, tighten the first telescopic cylinder 5 with the screws 6, install the trimming punching edge 11 on the fixing plate 7 and fix the position with the pressing blocks 8 on both sides, connect the power output end of the first telescopic cylinder 5 with the trimming punching edge 11 through the connecting block 10, so that the first telescopic cylinder 5 can push the slider 9 forward smoothly; S4, the electric wire of the first telescopic cylinder 5 is connected to the control valve of the punch press, and the punch press controls the cylinder to operate. The punch press starts to operate, and the first telescopic cylinder 5 is pushed forward to insert the trimming and punching blade 11 into the rolled part 3. The punch press reaches the bottom dead center position of the closed mold, and the first telescopic cylinder 5 is retracted to pull back the slider 9 to push out the rolled part 3.
