Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically, to a hard alloy stamping die. Background Art

[0002] Stamping is a forming method that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining workpieces of desired shape and size. After the stamping parts are formed, they generally no longer undergo cutting processing, or only require a small amount of cutting processing; with the rapid development of the manufacturing industry, the plates are also using mold processing to improve production efficiency due to the growing demand. The forming of metal plates is usually achieved by stamping. Most of the existing stamping dies are fixed, so when other parts need to be stamped, another matching stamping die needs to be used, which will increase the required cost.

[0003] According to the Chinese utility model publication number CN220515139U, a cemented carbide stamping die is disclosed, including a stamping table, and the upper surface of the stamping table is fixed with no less than two lower die seats, and the lower die seats are arranged at intervals along the length direction thereof. The utility model has the advantages of compact structure, reasonable design, convenient use and low cost. By setting a plurality of matching stamping components and lower die seats, the workpiece can be automatically stamped at the same time, so that multiple stamping parts can be stamped at one time, and the work efficiency is greatly improved. However, the stamping die set up in this way cannot replace the die, so when other parts need to be stamped, another matching stamping die needs to be used, which will increase the required cost. Therefore, in view of this problem, how to design a cemented carbide stamping die has become a problem that we need to solve at present. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a carbide stamping die.

[0011] In a preferred embodiment, a fixing pin is slidably connected inside the mounting plate, the fixing pin is inserted into the interior of the upper punch, and a pull plate is fixedly mounted on one end of the fixing pin.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model sets a base. When the stamped parts need to be replaced, the first adjusting screw is slid outward by rotating the first turning handle, and the side positioning frame is displaced, so that the side positioning frame slides out from the inside of the lower die. At the same time, the slider slides inside the base. After the side positioning frames on both sides are separated from the lower die, the lower die loses its limit. The lower die can be replaced by taking it out from the inside of the base, thereby achieving the purpose of conveniently replacing the stamping die.

[0014] 2. The utility model sets a mounting plate. When the upper punch needs to be replaced, the fixing pin is separated from the inside of the upper punch by pulling the pull plate, so that the upper punch loses its limit. At this time, the upper punch can be taken out from the inside of the mounting plate, and the required upper punch can be installed inside the mounting plate to complete the installation. When stamping, the mounting plate is lowered by starting the hydraulic cylinder. At this time, the upper punch enters the inner side of the lower die, and the required parts can be stamped out.

Figure 1As shown, the base 1 is internally slidably connected to a lower positioning frame 8, a connecting column 9 is fixedly installed at the bottom of the lower positioning frame 8, the connecting column 9 is slidably connected to the inside of the base 1, a lifting plate 10 is fixedly installed on the outside of the connecting column 9, and the lifting plate 10 is internally threadedly connected to a second adjusting screw 11.

[0021] It should be noted that, when the stamped parts need to be replaced, the first adjusting screw 4 is slid outward by rotating the first turning handle 7, and the side positioning frame 3 is driven to move, so that the side positioning frame 3 slides out from the inside of the lower die 2, and the slider 6 slides inside the base 1. After the side positioning frames 3 on both sides are separated from the lower die 2, the lower die 2 loses its limit. The lower die 2 is taken out from the inside of the base 1, so that the required lower die 2 can be replaced. The required lower die 2 is placed inside the base 1. Since the central part of the base 1 is provided with a The positioning groove can cooperate with the positioning protrusions on both sides of the base 1, so that when the lower die 2 is replaced, the lower die 2 can be located in the center position of the base 1. At this time, the side positioning frames 3 on both sides are allowed to enter the interior of the lower die 2 by rotating the first turning handles 7 on both sides, thereby fixing the lower die 2, and the lifting plate 10 drives the connecting column 9 to rise by rotating the second turning handle 12, so that the lower positioning frame 8 is brought into contact with the bottom of the base 1, thereby completing the fixing and limiting of the lower die 2, and then being able to stamp out the required parts, thereby achieving the purpose of convenient replacement of the stamping die.

[0022] Further, such as Figure 1 As shown, the second adjusting screw 11 is rotatably connected to the bottom of the base 1, a second turning handle 12 is fixedly installed at the bottom of the second adjusting screw 11, a supporting column 13 is fixedly installed at the bottom of the base 1, a second limiting frame 14 is fixedly installed on the top of the base 1, a hydraulic cylinder 15 is fixedly installed inside the second limiting frame 14, a mounting plate 16 is fixedly installed at the output end of the hydraulic cylinder 15, the mounting plate 16 is slidably connected to the inner side of the second limiting frame 14, and an upper punch 17 is inserted inside the mounting plate 16, as shown in FIG. Figure 3 As shown, a fixing pin 18 is slidably connected inside the mounting plate 16 , and the fixing pin 18 is inserted into the inside of the upper punch 17 , and a pull plate 19 is fixedly mounted on one end of the fixing pin 18 .

[0023] It should be noted that, when the upper punch 17 needs to be replaced, the fixing pin 18 is separated from the interior of the upper punch 17 by pulling the pull plate 19, so that the upper punch 17 loses its limit. At this time, the upper punch 17 can be taken out from the interior of the mounting plate 16, and then the required upper punch 17 can be installed inside the mounting plate 16 to complete the installation. When stamping, the mounting plate 16 is lowered by starting the hydraulic cylinder 15. At this time, the upper punch 17 enters the inner side of the lower sleeve die 2, and the required parts can be stamped out.
