Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die. Background Art

[0002] A stamping die is a special process equipment used in cold stamping to process metal or non-metal materials into parts or semi-finished products. It is called a cold stamping die, commonly known as a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the desired parts.

[0003] Patent application number CN202222097186.X discloses a stamping die with a replaceable stamping die head. When the stamping die in this scheme replaces the die base, only a single pair of upper dies can be replaced, but the upper die and the lower die are matching die. Therefore, when the upper die is replaced without replacing the lower die, the die cannot be completely matched during the stamping process, resulting in collision damage between the upper and lower dies, affecting the subsequent use of the stamping die. In addition, simply fixing the upper die head with screws will cause the screws to loosen after long-term use, causing the upper die to shift during use. Therefore, corresponding improvements are needed based on the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] according to Figure 1-Figure 4 As shown, it includes a workbench 1, a slide groove 11 is opened at one side of the top of the workbench 1, and a slider 12 is slidably connected inside the slide groove 11, a lower mold base 13 is installed at the top of the slider 12, and fixing grooves 14 are opened on both sides of the lower mold base 13.

[0020] A mounting plate 2 is installed at the other side of the top of the workbench 1, and a top plate 21 is installed at the top of one side of the mounting plate 2, a hydraulic telescopic rod 22 is installed at the top of the top plate 21, and a mounting plate 23 is installed at the bottom of the hydraulic telescopic rod 22, a through hole is opened in the top plate 21 near one end of the hydraulic telescopic rod 22, and one end of the hydraulic telescopic rod 22 passes through the inside of the top plate 21 through the through hole, a fixing cylinder 24 is installed at the bottom of the mounting plate 23, and fixing holes 25 are opened on the side walls of the fixing cylinder 24 near both sides.

[0021] A fixing column 31 is movably installed inside the fixing cylinder 24, and a connecting hole 32 is opened inside the fixing column 31. Screws 26 are penetrated inside the fixing hole 25 and the connecting hole 32, and nuts 27 are movably screwed on the outer surfaces of the screws 26 at both ends. The inner surfaces of the two sets of nuts 27 are fitted with the outer surface of the fixing cylinder 24. An upper mold base 3 is installed at the bottom end of the fixing column 31, and limit blocks 33 are installed on both sides of the upper mold base 3 at both ends. The upper mold base 3 is arranged directly above the lower mold base 13.

[0022] Limit rods 4 are installed on both sides of the bottom end of the top plate 21, and a limit groove 41 is provided on one side of the limit rod 4 near the bottom end. The limit block 33 is located inside the limit groove 41 and is slidably connected thereto. The bottom end of the limit groove 41 is open. The distance between the bottom end of the four groups of limit rods 4 and the top end of the lower die base 13 is greater than the thickness of the four groups of limit blocks 33. Electric push rods 5 are installed on the other two sides of the bottom end of the top plate 21, and a connecting plate 51 is installed on the bottom end of the electric push rod 5. A fixing plate 52 is installed on the bottom end of the connecting plate 51. The width of the fixing plate 52 is adapted to the distance between the inner walls on both sides of the fixing groove 14, and the fixing plate 52 is corresponding to the fixing groove 14.

[0023] When the shape of the stamping die needs to be changed, the lower die base 13 and the upper die base 3 need to be replaced at the same time. The specific steps are as follows: the user can first start the two sets of electric push rods 5 at the same time, so that the corresponding connecting plate 51 and the corresponding fixing plate 52 can move upward accordingly under the operation of the two sets of electric push rods 5, so that the corresponding fixing plate 52 can move upward accordingly in the interior of the corresponding fixing groove 14, so that it can move out from the interior of the corresponding fixing groove 14. After that, the user can rotate the nuts 27 screwed at both ends of the screw rod 26 accordingly, so that the two sets of nuts 27 can be rotated out from the corresponding ends of the nuts 27. After that, the screw 26 can be rotated out from the interior of the connecting hole 32 and the interior of the two sets of fixing holes 25, so that the fixing column 31 can be separated from the interior of the fixing cylinder 24, so that under the influence of gravity, the upper die base 3 can move downward accordingly, so that The four groups of limit blocks 33 can be moved downward in the corresponding limit grooves 41 respectively until the bottom end of the upper mold base 3 is located inside the lower mold base 13, and the bottom ends of the four groups of limit blocks 33 are overlapped on the top of the lower mold base 13. At this time, the user can move the lower mold base 13 to one side, so that the slider 12 can move to one side inside the slide groove 11, so that the upper mold base 3 can move synchronously, so that the lower mold base 13 and the upper mold base 3 can be disassembled synchronously, and then according to the above operation, the lower mold base 13 and the upper mold base 3 can be installed synchronously according to the above operation. After installation, the user can start the hydraulic telescopic rod 22, so that under the operation of the hydraulic telescopic rod 22, the installation plate 23 and the fixing cylinder 24 can move downward, so that the fixing column 31 and the upper mold base 3 can move downward accordingly. At the same time, the four groups of limit blocks 33 can move downward in the corresponding limit grooves 41 respectively. Thereby, the upper die base 3 can be more stable when moving downward, and when the bottom end of the upper die base 3 is located inside the lower die base 13, the die stamping operation can be performed.
