Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a material guiding device for stamping dies. Background Technology

[0002] Stamping dies are a type of processing equipment used for processing thin metal sheets. At room temperature, metal or non-metal sheets are placed into them, and pressure is applied by a press to separate or deform the sheets, ultimately producing the desired parts. They are widely used in manufacturing industries such as automobiles, home appliances, electronics, and aerospace.

[0003] Die stamping is one of the main methods for manufacturing metal parts, with advantages of high efficiency, high precision, and low cost, and occupies an important position in modern manufacturing. In order to keep the sheet metal in a straight line during the process of conveying it to the lower die base, a material guiding device for stamping dies has been designed. This device restricts the position of the sheet metal in the conveying state through the inclined plates on both sides, so that the sheet metal can be clamped with a limiting force during the conveying process. This ensures that the sheet metal is kept in a straight line during the process of conveying it to the lower die base, so as to avoid the situation where the sheet metal is skewed during the conveying process, which would adversely affect the quality of the stamped die product.

Detailed Implementation

[0023] In the following description, embodiments of the material guiding device for stamping dies of the present invention will be described with reference to the accompanying drawings.

[0024] Example 1:

[0025] Figure 1-5 This invention illustrates a material guiding device for a stamping die according to an embodiment of the present invention. It includes: a material support frame 3 disposed on the right side of a lower die base 1 and an upper die base 2; two hollow components 4 are bolted to the top of both the front and rear sides of the material support frame 3; U-shaped plates 5 are welded to the left and right sides of the inner cavity of each hollow component 4; multiple semi-circular holes 6 are formed in the inner cavity of each U-shaped plate 5; a perforated rod 7 is slidably connected to the inner cavity of the hollow component 4; a threaded hole is formed on the surface of the perforated rod 7; multiple limiting holes 8 are formed on the surface of the hollow component 4; a threaded thread 9 connects the inner cavity of the threaded hole and the limiting hole 8; a support plate 10 is welded to the side of the perforated rod 7 near the semi-circular hole 6; round tubes 11 are welded to the left and right sides of the support plate 10; and a circular ring is slidably connected to the inner cavity of the round tubes 11. 12. A spring 13 is welded between the inner cavities of the ring 12 and the tube 11. A ball bearing 14 is rotatably connected to the inner cavity of the ring 12. An opening plate 15 is bolted to the side of the opening rod 7 opposite to the support plate 10. The surface of the ball bearing 14 is rolled to the inner cavity of the semi-circular hole 6. A rod-supported inclined plate 16 is slidably connected to the inner cavity of the opening plate 15. A large spring 17 is welded between the rod-supported inclined plate 16 and the opening plate 15. Through the cooperation of the rod-supported inclined plate 16 and the large spring 17, the plate material can be given flexible support during the conveying process, which can avoid the support force of the opening plate 15 being too rigid, which would cause the plate material to be blocked during the conveying process. Two limit plates 19 are bolted to the top of the lower mold base 1.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates a material guiding device for a stamping die according to an embodiment of the present invention. It includes: a material support frame 3 disposed on the right side of a lower die base 1 and an upper die base 2; two hollow components 4 are bolted to the top of both the front and rear sides of the material support frame 3; U-shaped plates 5 are welded to the left and right sides of the inner cavity of each hollow component 4; multiple semi-circular holes 6 are formed in the inner cavity of each U-shaped plate 5; a perforated rod 7 is slidably connected to the inner cavity of the hollow component 4; a threaded hole is formed on the surface of the perforated rod 7; multiple limiting holes 8 are formed on the surface of the hollow component 4; a threaded connection 9 is formed between the inner cavity of the threaded hole and the limiting hole 8; a support plate 10 is welded to the side of the perforated rod 7 near the semi-circular hole 6; round tubes 11 are welded to the left and right sides of the support plate 10; and a threaded connection 9 is formed to the inner cavity of the round tubes 11. A spring 13 is welded between the inner cavities of the ring 12 and the tube 11. A ball bearing 14 is rotatably connected to the inner cavity of the ring 12. The side of the perforated rod 7 opposite to the support plate 10 is fixedly connected to the perforated plate 15 by bolts. The side of the rod-adding inclined plate 16 opposite to the perforated plate 15 is fixedly connected to the L-shaped plate 18 by bolts. By setting the L-shaped plate 18, the rod-adding inclined plate 16 can limit and support the plate while giving the plate a downward compressive force, which can prevent the plate from bouncing upward due to its thin material. The tops of the two limiting plates 19 are fixedly connected to the additional mold 20 by bolts. A conveyor 21 is set on the right side of the lower mold base 1. The conveyor 21 is located between the lower mold base 1 and the material support frame 3.

[0028] Working principle: When using this invention, the user pulls the perforation plate 15 according to the width of the sheet metal, causing the perforation rod 7 to slide within the cavity of the hollow part 4. Then, supported by the support plate 10 and the round tube 11, the ball 14 disengages from the cavity of the semi-circular hole 6. Next, under the fixed support of the ring 12 and the spring 13, the surface of the ball 14 rolls against the inner wall of the U-shaped plate 5 until it slides to the position of another semi-circular hole 6. Subsequently, the rebound force of the spring 13 returns the ball 14 to its original position, thus facilitating the threaded hole on the surface of the perforation rod 7. The position of the limiting hole 8 is accurately located, and the thread 9 is used to fix the position of the opening rod 7, thereby allowing the limiting range of the rod inclined plate 16 to be flexibly adjusted. Then, the conveyor 21 is started to transport the sheet material to the direction of the lower die base 1. During the conveying process, the sheet material is limited by the rod inclined plate 16 and the large spring 17, so that the sheet material can maintain a straight line of translation and sliding during the conveying process to the direction of the lower die base 1, so as to avoid the situation where the sheet material is skewed during the conveying process, which would have an adverse effect on the quality of the stamped die product.

[0029] In summary, this stamping die guiding device, through the cooperation of the ball bearing 14 and the semi-circular hole 6, facilitates the accurate positioning of the threaded hole on the surface of the opening rod 7 and the limiting hole 8, thereby facilitating the fixing of the opening rod 7 by the thread 9. This allows for flexible adjustment of the limiting range of the inclined plate 16, achieving the goal of keeping the sheet metal in a straight line during the conveying process to the lower die base 1. This avoids the sheet metal from becoming skewed during conveying, which could adversely affect the quality of the stamped die product.
