[0002] Stamping refers to a processing method that uses a press and dies to apply external force to sheet metal, strip, tube and profile materials to cause plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips.

[0003] A search revealed that Chinese patent publication number CN 210208320 U discloses a metal cap stamping die, relating to the field of stamping forming technology. This metal cap stamping die includes a die base and a movable die located above it. A fixed die is installed inside the die base, and a bottom fixing plate is fixed to the bottom of the die base. A top fixing plate is installed at the top of the movable die, and a punch is fixed to the bottom of the movable die. A cavity matching the punch is opened inside the fixed die. Fixing seats are installed at the four corners of the upper surface of the die base, and each of the four fixing seats is internally connected to a screw via a threaded connection. This invention, through the arrangement of screws, fixing seats, and clamping plates, allows the worker to adjust the four clamping plates according to the size of the metal cap workpiece during stamping, and then clamp the metal cap workpiece using the four clamping plates, thereby achieving the clamping of metal cap workpieces of different sizes, increasing the range of applications of the die, and improving its practicality.

[0004] The stamping dies in the aforementioned patent still have certain shortcomings. In actual use, the existing metal cap stamping dies lack an effective limiting structure for feeding metal strips. This can easily lead to unqualified stamped products due to skewed feeding of the strips, wasting raw materials, increasing production costs, and reducing the stamping efficiency of the dies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a metal cap stamping die, which solves the problem that existing metal cap stamping dies lack an effective limiting structure for feeding metal strips during actual use. This leads to unqualified stamped products due to skewed feeding of the strips, wasting raw materials, increasing production costs, and reducing the stamping efficiency of the die.

[0006] This utility model provides the following technical solution: a metal cover stamping die, including a bottom die base, a die cavity provided on the bottom die base, a top die base provided on the top of the bottom die base, a protruding module provided on the bottom of the top die base, guide posts evenly arranged around the bottom end of the top die base, guide grooves evenly opened around the top end of the bottom die base, and two stamping auxiliary feeding components symmetrically arranged on both sides of the bottom die base;

[0007] The stamping auxiliary feeding assembly includes a side fixing block fixed to the side of the bottom die base. A rotating groove is formed in the middle of the top of the side fixing block. Three supporting rollers are evenly arranged in the rotating groove. The two ends of the supporting rollers are rotatably connected to the inner wall of the rotating groove through bearings. Two limiting contact plates are symmetrically arranged on both sides of the top of the side fixing block. Two limiting slide grooves are symmetrically formed on both sides of the top of the side fixing block. Two limiting sliders are symmetrically arranged on both sides of the bottom end of the limiting contact plates. The limiting sliders are slidably inserted into the limiting slide grooves. Two pushing slide slots are symmetrically formed on both sides of the top of the side fixing block. A fixing connecting block is fixed to the side of the limiting contact plate. A bottom driving chamber is formed at the bottom of the side fixing block. A driving screw is rotatably inserted in the bottom driving chamber. Two driving sleeves are symmetrically fitted at both ends of the driving screw.

[0008] Preferred technical solution 1: The end of the drive screw rotates through the side fixing block, the end of the drive screw is provided with a throttle handle, the top of the drive screw sleeve is provided with a push connecting plate, and the top of the push connecting plate passes through the push sliding joint and is fixedly connected to the fixing connecting block.

[0009] Preferred technical solution 2: A feeding support plate is provided at the top of the side of the side fixing block, and the bottom end of the feeding support plate is fixedly connected to the side fixing block through two reinforcing support rods.

[0010] Preferred technical solution 3: The top surface of the supporting roller and the top surface of the side fixing block are located on the same horizontal plane.

[0011] This solution enables the steel plate to be stamped on the top side of the side fixing block to receive rotational support from the supporting roller.

[0012] Preferred technical solution four: the thread directions at both ends of the drive screw are opposite, and the drive sleeve cooperates with the drive screw.

[0013] This solution enables the drive screw to simultaneously drive the two drive sleeves fitted on it to move closer to each other.

[0014] Preferred technical solution five: The feeding support plate is inclinedly disposed at the top of the side of the side fixing block.

[0015] This solution enables the feeding support plate to better support the steel plate being stamped.

[0016] Compared with the prior art, this utility model provides a metal cover stamping die with the following advantages: This utility model symmetrically arranges stamping auxiliary feeding components on both sides of the bottom die base. The side fixing blocks in the stamping auxiliary feeding components are fixed to both sides of the bottom die base, and the top surface of the side fixing blocks is on the same horizontal plane as the top surface of the bottom die base. When the user needs to stamp a steel plate, the user can insert the steel plate through the top of the side fixing blocks. By rotating the drive screw, the drive screw drives two limiting contact plates through the drive screw sleeve to abut against both sides of the steel plate, thereby effectively limiting both sides of the steel plate. This design is suitable for stamping steel plates of different widths, making the stamping of the steel plate more stable, thereby improving the pass rate of stamped products and increasing the stamping efficiency, and facilitating user processing.

[0023] Please see Figure 1-4 ,

[0024] Example 1: A metal cap stamping die includes a bottom die base 1, a die cavity 2 on the bottom die base 1, a top die base 3 on the top of the bottom die base 1, a protruding module 4 on the bottom of the top die base 3, guide posts 5 evenly arranged around the bottom of the top die base 3, guide grooves 6 evenly opened around the top of the bottom die base 1, and two stamping auxiliary feeding components 7 symmetrically arranged on both sides of the bottom die base 1.

[0025] The stamping auxiliary feeding assembly 7 includes a side fixing block 701 fixed to the side of the bottom die base 1. A rotating groove 702 is provided in the middle of the top of the side fixing block 701. Three supporting rollers 703 are evenly arranged in the rotating groove 702. The two ends of the supporting rollers 703 are rotatably connected to the inner wall of the rotating groove 702 through bearings. Two limiting contact plates 704 are symmetrically arranged on both sides of the top of the side fixing block 701. Two limiting slide grooves 705 are symmetrically opened on both sides of the top of the side fixing block 701. Two limiting sliders 706 are symmetrically arranged on both sides of the bottom end of the limiting contact plates 704. The limiting sliders 706 are slidably inserted into the limiting slide grooves 705. Two pushing slide slots 707 are symmetrically opened on both sides of the top of the side fixing block 701.

[0026] A fixed connecting block 708 is fixed to the side of the limiting contact plate 704. A bottom driving chamber 709 is opened at the bottom of the side fixed block 701. A driving screw 710 is rotatably inserted into the bottom driving chamber 709. Two driving screw sleeves 711 are symmetrically sleeved at both ends of the driving screw 710. The end of the driving screw 710 rotatably passes through the side fixed block 701. A handle 712 is provided at the end of the driving screw 710. A push connecting plate 713 is provided at the top of the drive screw sleeve 711. The top of the push connecting plate 713 passes through the push sliding joint 707 and is fixedly connected to the fixed connecting block 708. A feeding support plate 714 is provided at the top of the side of the side fixed block 701. The bottom end of the feeding support plate 714 is fixedly connected to the side fixed block 701 through two reinforcing support rods 715.

[0027] Example 2: The difference between this example and Example 1 is that the top surface of the support roller 703 and the top side surface of the side fixing block 701 are located on the same horizontal plane.

[0028] This allows the steel plate to be stamped on the top side of the side fixing block 701 to receive rotational support from the supporting roller 703.

[0029] Example 3: The difference between this example and Example 1 is that the threads at both ends of the drive screw 710 are in opposite directions, and the drive sleeve 711 is engaged with the drive screw 710.

[0030] This allows the drive screw 710 to simultaneously drive the two drive sleeves 711 fitted on it to move closer to each other.

[0031] Example 4: The difference between this example and Example 1 is that the feeding support plate 714 is inclinedly arranged at the top of the side of the side fixing block 701.

[0032] This allows the 714 feeding support plate to better support the steel plate being stamped.

[0033] In this embodiment, because the existing metal cap stamping die lacks an effective limiting structure for feeding metal strips in actual use, the stamped product is prone to defects due to the skewed feeding of the strip, which wastes raw materials, increases production costs, and reduces the stamping efficiency of the die.

[0034] In summary, during implementation, when the user needs to place the steel plate on the mold cavity 2 for stamping, the user can first rotate the drive screw 710, causing the two drive screw sleeves 711 mounted on it to move closer together synchronously. The drive screw sleeves 711 then push the connecting plate 713 to slide in the push sliding joint 707, thereby limiting the drive screw sleeves 711 so that they do not rotate with the rotation of the drive screw 710. This allows the drive screw sleeves 711 to drive the limiting contact plate 704 to move closer together on the side fixing block 701 through the fixed connecting block 708, thereby limiting the two sides of the steel plate placed on the top support roller 703 of the side fixing block 701, making the steel plate laid on the top of the mold cavity 2 more straight and stable.

[0035] The top center of the side fixing block 701 has a rotating groove 702. The bottom of the steel plate is rotated and supported by the rotating support roller 703 in the rotating groove 702, which makes the steel plate smoother when it is loaded and will not cause scratches due to excessive friction with the top of the side fixing block 701. This makes the surface of the product obtained by stamping through the cooperation of the convex module 4 and the die cavity 2 smoother, effectively improving the pass rate of stamped products and the stamping efficiency of products, and making it convenient for users.
