[0002] A composite stamping die for parts is a type of die that can complete multiple processes during the stamping process. It typically consists of two parts: an upper die and a lower die. The upper and lower dies are assembled by guide pillars and guide sleeves. During the stamping process, the die can simultaneously complete multiple processes such as blanking, drawing, punching, and bending at the same station, thereby improving production efficiency and material utilization.

[0003] Commonly available composite stamping dies for parts have good stamping function during use. However, due to the lack of limiting structure in the die, the raw material may be misaligned due to human factors before stamping, resulting in a large amount of material waste and increased stamping costs. Summary of the Invention

[0033] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] like Figures 1 to 4 As shown in the figure, a composite stamping die for parts provided in this embodiment of the present invention includes:

[0035] Base 1;

[0036] Lower mold 2: The lower surface of the lower mold 2 is fixedly connected to the upper surface of the base 1;

[0037] Upper mold 3: The lower surface of the upper mold 3 is fixedly connected to the upper surface of the upper mold 3;

[0038] Limiting mechanism 4: Two limiting mechanisms 4 are provided, both of which are located inside the lower mold 2. The limiting mechanism 4 includes:

[0039] Limiting plate 410: The limiting plate 410 is provided on the upper surface of the lower mold 2;

[0040] Connecting plate 420: The upper surface of the connecting plate 420 is fixedly connected to the lower surface of the limiting plate 410;

[0041] Sliding groove 430: The sliding groove 430 is formed on the upper surface of the lower mold 2, and the inner wall of the sliding groove 430 is slidably connected to the outer surface of the connecting plate 420;

[0042] Stroke assembly 440: There are two stroke assemblies 440, both of which are located on both sides of the connecting plate 420.

[0043] refer to Figure 3 As shown, the travel component 440 includes;

[0044] First stroke column 441: The first stroke column 441 is fixedly connected to both sides of the connecting plate 420 at one end;

[0045] Stroke component 442: The inner wall of stroke component 442 is slidably connected to the outer surface of the first stroke column 441.

[0046] Using the above solution: the stroke member 442 rotates, and the inner wall of the stroke member 442 presses against the outer surface of the first stroke column 441, so that the first stroke column 441 moves along the inner wall of the stroke member 442. The first stroke column 441 can drive the limiting plate 410 to move to the opposite side along the inner wall of the sliding groove 430 through the connecting plate 420, so as to realize the function of limiting and fixing the raw material by the limiting plate 410.

[0047] refer to Figure 3 As shown, the surface of the stroke component 442 is provided with support columns 5. There are two support columns 5. The outer surfaces of the two support columns 5 are fixedly connected to the inside of the stroke component 442. The front and rear ends of the support columns 5 are rotatably connected to the inner wall of the lower mold 2 through a rotating shaft. The outer surface of the support columns 5 is provided with a transmission component 6.

[0048] Using the above scheme: the support column 5 mainly serves to support the stroke component 442 and the gear 601.

[0049] refer to Figure 4 As shown, there are two transmission components 6, each including:

[0050] Gear 601: The inner wall of gear 601 is fixedly connected to the outer surface of support column 5;

[0051] Gear plate 602: The upper surface of gear plate 602 is in a meshing relationship with the outer surface of gear 601.

[0052] Using the above scheme: In order to make the stroke member 442 rotate, the toothed plate 602 moves to the opposite side, and the toothed plate 602 can mesh with the gear 601, so that the gear 601 rotates. The gear 601 can drive the stroke member 442 to rotate together through the support column 5.

[0053] refer to Figure 4 As shown, a sliding rail 7 is provided inside the toothed plate 602. Both ends of the sliding rail 7 are fixedly connected to the inner wall of the base 1, and the outer surface of the sliding rail 7 is slidably connected to the inside of the toothed plate 602.

[0054] Using the above scheme, the sliding rail 7 mainly serves to provide support and a movement path for the toothed plate 602.

[0055] refer to Figure 4 As shown, a drive assembly 8 is provided on the lower surface of the toothed plate 602. The drive assembly 8 includes:

[0056] Second stroke column 801: There are two second stroke columns 801, and the upper end faces of the two second stroke columns 801 are fixedly connected to the lower surface of the toothed plate 602.

[0057] Servo motor 802: The outer surface of servo motor 802 is fixedly connected to the inner wall of base 1;

[0058] Support plate 803: The lower surface of the support plate 803 is fixedly connected to the output end of the servo motor 802, and the upper surface of the support plate 803 is slidably connected to the outer surface of the second stroke column 801.

[0059] Using the above solution: In order to move the toothed plate 602 to the opposite side, the servo motor 802 drives the support plate 803 to rotate. The inner wall of the support plate 803 presses against the outer surface of the second stroke column 801, so that the second stroke column 801 slides along the inner wall of the support plate 803 and drives the toothed plate 602 to move to the opposite side.

[0060] In use, the servo motor 802 drives the support plate 803 to rotate. The inner wall of the support plate 803 presses against the outer surface of the second stroke column 801, causing the second stroke column 801 to slide along the inner wall of the support plate 803 and drive the toothed plate 602 to move to the opposite side. The toothed plate 602 can mesh with the gear 601, causing the gear 601 to rotate. The gear 601 can drive the stroke member 442 to rotate together through the support column 5. The inner wall of the stroke member 442 presses against the outer surface of the first stroke column 441, causing the first stroke column 441 to move along the inner wall of the stroke member 442. The first stroke column 441 can drive the limiting plate 410 to move to the opposite side along the inner wall of the sliding groove 430 through the connecting plate 420. The limiting plate 410 limits and fixes the material. Then, the upper mold 3 moves down to stamp the material.

[0061] It should be noted that the servo motor 802 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the servo motor 802 are clear to those skilled in the art, so they will not be described in detail here.
