Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a stamping mold with a workpiece stabilizing device. Background Technology

[0002] Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. Stamping dies with workpiece stabilization devices are essential process equipment in stamping production. The quality of stamped parts, production efficiency, and production costs are directly related to the design and manufacture of the dies.

[0003] Existing stamping dies are generally divided into upper dies and lower dies. The workpiece to be stamped is first placed into the lower die, and the stamping machine drives the upper die to stamp the workpiece in the lower die. However, this type of stamping die often causes the workpiece to shift position due to the lack of fixation in the lower die, which affects the yield. In addition, sometimes the workpiece is easy to get stuck in the lower die and is not easy to remove, which affects the stamping efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a stamping die with a workpiece stabilizing device, thereby solving the problems mentioned in the background section. To achieve the above objective, the present utility model adopts the following technical solution:

[0005] The stamping die with a workpiece stabilizing device includes an upper die and a lower die, and further includes a workpiece stabilizing device disposed on the lower die and a control device disposed on the upper die. The workpiece stabilizing device includes a first stabilizing frame and a second stabilizing frame that are intersected and rotatably connected to each other. A first spring is disposed at a first end of the first stabilizing frame and is connected to one side of the lower die to keep the second end of the first stabilizing frame away from the second end of the second stabilizing frame. A second spring is disposed at a first end of the second stabilizing frame and is connected to the other side of the lower die to keep the second end of the second stabilizing frame away from the second end of the first stabilizing frame. The control device is used to bring the first end of the first stabilizing frame and the first end of the second stabilizing frame closer to each other, thereby bringing the second end of the first stabilizing frame and the second end of the second stabilizing frame closer to each other to clamp the workpiece.

[0006] Optionally, a first roller is provided at the first end of the first stabilizer, and a second roller is provided at the second end of the second stabilizer, with the first roller and the second roller respectively tactilely connected to the control device.

[0007] Optionally, the control device includes a control board with a V-groove that is tactilely connected to the first roller and the second roller, respectively.

[0008] Optionally, the upper die includes a stabilizing seat, a guiding assembly, an upper die holder, and a stamping head. The guiding assembly passes through the stabilizing seat and is slidably connected to the stabilizing seat. The upper die holder is disposed at one end of the guiding assembly near the lower die. The stamping head is disposed inside the upper die holder. The control device is disposed on one side of the upper die holder.

[0009] Optionally, it also includes a support frame and a stamping cylinder, wherein the stabilizing seat and the lower die are respectively disposed opposite to each other in the support frame, and the stamping cylinder is disposed on the support frame, with its working end connected to the guide assembly.

[0010] Optionally, the guide assembly includes a connecting shaft and a guide rod that pass through the stabilizer and are slidably connected to the stabilizer. One end of the connecting shaft is connected to the working end of the stamping cylinder, and the other end is connected to the upper die base. The guide rod is connected to the upper die base.

[0011] Optionally, a demolding hole is provided on the lower mold base at the position corresponding to the workpiece, and the demolding hole is connected to external high-pressure gas.

[0012] Compared to existing technologies, the advantages of this invention are as follows: By setting a workpiece stabilizing device on the lower die and using a first spring and a second spring to keep the tops of the first and second stabilizing frames far apart, it facilitates the placement and removal of workpieces. By setting a control device at the bottom of the upper die, during stamping, the control device simultaneously controls the tops of the first and second stabilizing frames to move closer together, clamping and positioning the workpiece. The upper and lower dies then stamp the workpiece, solving the problem that existing stamping dies often suffer from workpiece position shifts due to the lack of fixation in the lower die, which affects the yield rate. Furthermore, by providing a demolding hole at the top of the lower die base, after stamping, external high-pressure gas blows the workpiece upward through the demolding hole, preventing the workpiece from getting stuck in the lower die and affecting stamping efficiency.

[0022] like Figures 1-2 As shown, one embodiment of this utility model is:

[0023] The stamping die with a workpiece stabilizing device includes an upper die 1 and a lower die 2, and also includes a workpiece stabilizing device 3 disposed on the upper part of the lower die 2 and a control device 4 disposed on the bottom of the upper die 1. The workpiece stabilizing device 3 includes a first stabilizing frame 31 and a second stabilizing frame 32 that are intersected and rotatably connected. A first spring 33 is disposed at the bottom end of the first stabilizing frame 31 and is connected to the left side of the lower die 2 to keep the upper end of the first stabilizing frame 31 away from the upper end of the second stabilizing frame 32. A second spring 34 is disposed at the lower end of the second stabilizing frame 32 and is connected to the right side of the lower die 2 to keep the upper end of the second stabilizing frame 32 away from the upper end of the first stabilizing frame 31. The control device 4 is used to bring the bottom ends of the first stabilizing frame 31 and the bottom ends of the second stabilizing frame 32 closer together, thereby clamping the workpiece on the top of the lower die 2.

[0024] In the initial state, the first spring 33 causes the bottom end of the first stabilizer 31 to move to the left and the top end of the first stabilizer 31 to move to the right. The second spring 34 causes the bottom end of the second stabilizer 32 to move to the right and the top end of the second stabilizer 32 to move to the left. The workpiece to be stamped is placed on the top of the lower die 2. The upper die 1 moves downward. The control device 4 first contacts the bottom of the first stabilizer 31 and the second stabilizer 32 and simultaneously drives the bottom of the first stabilizer 31 and the bottom of the second stabilizer 32 to move closer to each other. This causes the top of the first stabilizer 31 and the top of the second stabilizer 32 to move closer to each other and clamp the workpiece on the top of the lower die 2. The upper die 1 continues to move downward and contacts the lower die 2, stamping the workpiece. The upper die 1 separates from the lower die 2. The first spring 33 and the second spring 34 reset the first stabilizer 31 and the second stabilizer 32. At this time, the formed workpiece can be taken out.

[0025] This application solves the problem that existing stamping dies often suffer from workpiece position shifts and reduced yield due to the lack of workpiece fixation in the lower die 2. By setting a workpiece stabilizing device 3 on the lower die 2 and using a first spring 33 and a second spring 34 to keep the tops of the first stabilizing frame 31 and the second stabilizing frame 32 far apart from each other, it facilitates the picking and placing of workpieces. By setting a control device 4 at the bottom of the upper die 1, during stamping, the control device 4 simultaneously controls the tops of the first stabilizing frame 31 and the second stabilizing frame 32 to move closer to each other, clamping and positioning the workpiece. The upper die 1 and the lower die 2 then stamp the workpiece into shape.

[0026] In one embodiment, such as Figure 2 As shown, the bottom end of the first stabilizer 31 is provided with a first roller 35, and the bottom end of the second stabilizer 32 is provided with a second roller 36. When the control device 4 moves downward, the first roller 35 and the second roller 36 are respectively rolledly connected to the control device 4 to reduce the friction between the control device 4 and the first stabilizer 31 and the second stabilizer 32, thereby improving the stability of the stabilizing device during operation.

[0027] In one embodiment, such as Figure 3 As shown, the control device 4 includes a control plate 41. The bottom end of the control plate 41 is provided with an inverted V-shaped groove 42. The inner left side wall of the V-shaped groove 42 is rolledly connected to the first roller 35, and its inner right side wall is rolledly connected to the second roller 36. When the control plate 41 moves downward, under the constraint of the V-shaped groove 42, the bottom ends of the first stabilizer 31 and the second stabilizer 32 are brought closer to each other, thereby bringing the tops of the first stabilizer 31 and the second stabilizer 32 closer to each other.

[0028] In one embodiment, such as Figure 4 As shown, the upper die 1 includes a stabilizing seat 11, a guiding component 12, an upper die base 13, and a punching head 14. The guiding component 12 penetrates vertically through the stabilizing seat 11 and is slidably connected to the stabilizing seat 11. The upper die base 13 is located at the bottom of the guiding component 12, the punching head 14 is located at the bottom of the upper die base 13, and the control device 4 is located at the front of the upper die base 13.

[0029] During operation, the stabilizing seat 11 remains stationary, constraining the movement trajectory of the guide component 12. The guide component 12 moves vertically within the stabilizing seat 11, driving the upper die seat 13 and the control device 4 to move vertically. The stamping head 14 and the lower die seat 2 cooperate to form the workpiece.

[0030] In one embodiment, there are two first springs 33, respectively located on the front and rear sides of the bottom end of the first stabilizer 31; two second springs 34, respectively located on the front and rear sides of the bottom end of the second stabilizer 32; two first rollers 35, respectively located on the front and rear sides of the bottom end of the first stabilizer 31; two second rollers 36, respectively located on the front and rear sides of the bottom end of the second stabilizer 32; and two control plates 41, respectively located on the front and rear sides of the upper mold base 13. The front control plate 41 is rotatably connected to the front first rollers 35 and 36, and the rear control plate 41 is rotatably connected to the rear first rollers 35 and 36, thus further improving the stability of the stabilizing device and the control device 4 during operation.

[0031] In one embodiment, such as Figure 4 As shown, it also includes a support frame 5 and a stamping cylinder 6. The stabilizing seat 11 is located at the top of the support frame 5, the lower die 2 is located at the bottom of the support frame 5, and the stamping cylinder 6 is located at the top of the support frame 5. Its working end is connected to the guide assembly 12. The stamping cylinder 6 drives the guide assembly 12 to move vertically under the constraint of the stabilizing seat 11.

[0032] In one embodiment, such as Figure 4As shown, the guide assembly 12 includes a connecting shaft 121 and a guide rod 122 that pass through the stabilizer 11 and are slidably connected to the stabilizer 11. The top end of the connecting shaft 121 is connected to the working end of the stamping cylinder 6, and its bottom end is connected to the upper mold base 13. The bottom end of the guide rod 122 is connected to the upper mold base 13, and its middle part is slidably connected to the stabilizer 11. The guide rod 122 and the connecting shaft 121 cooperate to ensure the running stability of the upper mold base 13.

[0033] In one embodiment, such as Figure 2 As shown, a demolding hole 7 is provided on the top of the lower die 2 corresponding to the position of the workpiece. The demolding hole 7 is connected to external high-pressure gas. After the stamping is completed, the external high-pressure gas blows the workpiece upward through the demolding hole 7 to prevent the workpiece from getting stuck in the lower die 2 and affecting the stamping efficiency.

[0034] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
