Description

Technical Field

[0001] This invention relates to the field of stamping die technology, specifically to a stamping die with positioning, error prevention, and foolproof features. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press at room temperature to apply pressure to materials, causing them to separate or plastically deform, thereby obtaining the desired parts. Stamping dies are divided into upper dies and lower dies. The stamping of workpieces is achieved by the continuous up and down movement of the upper die.

[0003] The existing technology has the following problems:

[0004] In the process of stamping products, conventional stamping dies require manual loading and unloading of the stamped product before new products are placed in for stamping. This reduces the efficiency of the stamping process. Furthermore, conventional dies do not have automatic positioning capabilities, which can easily lead to stamping deviation and reduce the quality of the stamped products. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a stamping die with positioning, error prevention, and foolproof features, solving the problems of low operating efficiency and lack of automatic positioning in current stamping dies, which easily lead to stamping deviation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping die with positioning, error prevention, and foolproof features, comprising a die base, a stamping platform at the upper end of the die base, a stamping groove on the upper surface of the stamping platform, a stamping die at the upper end of the stamping groove, a stamping drive component at the upper end of the stamping die, a first gear connected to the lower end of the stamping platform, a second gear on the side of the first gear, a driven wheel connected to the upper end of the second gear, a belt on the outer side of the driven wheel, a drive wheel at one end of the belt, a motor at the lower end of the drive wheel, a reciprocating lead screw connected to the upper end of the drive wheel, a cross plate on the outer side of the reciprocating lead screw, an electric telescopic rod inside the die base, an electric contact rod connected to the upper end of the cross plate, a movable rod on one side of the electric telescopic rod, a positioning component at one end of the movable rod, a movable groove on the lower surface of the stamping platform, an electric contact piece on one side of the movable groove, and a positioning groove on the outer side of the movable groove.

[0007] As a preferred embodiment of the present invention, the number of stamping grooves is six, and the six stamping grooves are centrally symmetrically distributed on the upper surface of the stamping table.

[0008] As a preferred embodiment of the present invention, the second gear is a gear that is half toothed and half smooth, and the first gear and the second gear are movably connected.

[0009] In a preferred embodiment of the present invention, the movable rod is rotatably connected to the electric telescopic rod via a shaft, and the movable rod is rotatably connected to the positioning component via a shaft.

[0010] As a preferred embodiment of the present invention, the size of the positioning member matches the internal size of the positioning groove, and the positioning member is engaged with the stamping table through the positioning groove.

[0011] As a preferred embodiment of the present invention, the number of the electric shock rods is two, and the distance between the two electric shock rods matches the length of the electric shock plate.

[0012] As a preferred embodiment of the present invention, a top member is provided at the bottom of the stamping groove, a spring is provided at the lower end of the top member, and the top member is located at the center of the bottom of the stamping groove.

[0013] Compared with the prior art, the present invention provides a stamping die with positioning error prevention and foolproof features, which has the following beneficial effects:

[0014] 1. This stamping die with positioning error prevention and foolproof features includes a stamping table, stamping groove, first gear, second gear, drive wheel, belt, driven wheel, reciprocating screw, cross plate, contact piece, and contact rod. During the stamping process, the die not only enables simultaneous stamping and loading / unloading but also allows real-time monitoring of the stamping groove's position. Only when the bottom contact piece contacts the contact rod can a signal be automatically sent to control the stamping drive component, preventing stamping groove misalignment that could damage the product. Stamping can only be performed in the correct position, thus improving the positioning error prevention effect of the stamping die.

[0015] 2. This stamping die with positioning error prevention and foolproof features is equipped with an ejector, spring, electric telescopic rod, movable rod, positioning element, movable rod, movable groove, and positioning groove. When the stamping die is stamping the product, the positioning element moves inside the positioning groove, preventing the stamping table from continuing to move due to inertia, ensuring the stamping stability of the stamping die, preventing stamping misalignment, and improving the stamping quality of the product.

[0022] Please see Figure 1-4 In this embodiment: a stamping die with positioning error prevention and foolproof features includes a die base 1, a stamping platform 2 at the upper end of the die base 1, a stamping groove 3 on the upper surface of the stamping platform 2, a stamping die 4 at the upper end of the stamping groove 3, a stamping drive component 5 at the upper end of the stamping die 4, a first gear 6 connected to the lower end of the stamping platform 2, a second gear 7 on the side of the first gear 6, a driven wheel 8 connected to the upper end of the second gear 7, a belt 9 on the outer side of the driven wheel 8, and a drive wheel 10 at one end of the belt 9. A motor 11 is installed at the lower end of the drive wheel 10, and a reciprocating screw 12 is connected to the upper end of the drive wheel 10. A horizontal plate 13 is installed on the outer side of the reciprocating screw 12. An electric telescopic rod 14 is installed inside the mold base 1. An electric contact rod 15 is connected to the upper end of the horizontal plate 13. A movable rod 18 is installed on one side of the electric telescopic rod 14. A positioning element 19 is installed at one end of the movable rod 18. A movable groove 21 is opened on the lower surface of the stamping table 2. An electric contact piece 20 is installed on one side of the movable groove 21. A positioning groove 22 is installed on the outer side of the movable groove 21.

[0023] In this embodiment, there are six stamping slots 3, which are centrally symmetrically distributed on the upper surface of the stamping table 2. This enables simultaneous stamping operations and loading / unloading, improving mold stamping efficiency. The second gear 7 is a gear with one half having teeth and the other half being smooth. The first gear 6 is movably connected to the second gear 7, enabling intermittent rotation of the stamping table 2, with each rotation being 60 degrees. The movable rod 18 is rotatably connected to the electric telescopic rod 14 via a shaft, and the movable rod 18 is rotatably connected to the positioning component 19 via a shaft, providing good mobility. The dimensions of the positioning component 19 are consistent with those of the positioning slot 22. The internal dimensions are matched, and the positioning part 19 is engaged with the stamping table 2 through the positioning groove 22. It is used for positioning and fixing the stamping table 2 during stamping to prevent the stamping table from moving during stamping and improve the stamping quality. There are two electric contact rods 15, and the distance between the two electric contact rods 15 matches the length of the electric contact piece 20 to realize the detection function of stamping operation and ensure stamping accuracy. A top part 16 is provided at the bottom of the stamping groove 3. A spring 17 is provided at the lower end of the top part 16, and the top part 16 is located at the bottom center of the stamping groove 3 to push the product and facilitate unloading.

[0024] The working principle and usage process of this invention: During mold operation, the motor 11 drives the drive wheel 10 and the reciprocating screw 12 to rotate, and the belt 9 drives the driven wheel 8 and the second gear 7 to move. During the process, the second gear 7 intermittently drives the first gear 6 and the stamping table 2 to rotate, rotating 60 degrees each time. The operator places the product into the stamping groove 3 in sequence. When the stamping groove 3 with the product moves to the bottom of the stamping die 4, the reciprocating screw 12 rotates, causing the horizontal plate 13 to move up and down reciprocally. At this time, the reciprocating screw 12 rotates, causing the electric contact rod 15 to connect with the lower electric contact piece 20. When the controller touches the stamping drive 5, it will move the stamping die 4 downward to stamp the product. When there is no contact, it means that the stamping groove 3 is not directly below the stamping die 4, and the stamping table 2 needs to be adjusted. When the stamping groove 3 with the stamped product moves to the far right, the electric telescopic rod 14 extends and moves the movable rod 18, pushing the positioning part 19 to the right. The positioning part 19 moves into the positioning groove 22 and limits the stamping table 2. At the same time, the top of the electric telescopic rod 14 pushes the top part 16 upward to push the product out. After the stamping is completed, it returns to the initial position.
