Description

Technical Field

[0001] The utility model relates to the technical field of cold stamping dies, in particular to a blanking and unloading die. Background Art

[0002] In the modern manufacturing industry, cold stamping is one of the key metal forming technologies and is widely used in various fields, such as aerospace, automobiles, and electrical equipment. This processing technology relies on precise molds to quickly form metal sheets into specific parts. In this process, the unloading structure plays a vital role to ensure that the stamped parts can be smoothly unloaded from the mold. The existing unloading structures are mainly rigid unloading and elastic unloading. The rigid unloading structure is suitable for thicker plates, such as 0.8 mm and above. It has a large unloading force but no edge pressing effect, which results in the inability to provide satisfactory finished product quality when the flatness requirements are high. Although the elastic unloading structure is suitable for thin plates and medium plates, it provides a certain edge pressing effect to improve the flatness, but its unloading force is small and insufficient to handle thick plates, which limits its application range. In summary, the main shortcomings of the existing technology are that it cannot take into account the needs of materials of different thicknesses, especially in the processing of thick plates under high load conditions and applications with high flatness requirements.

[0003] Therefore, there is an urgent need to develop a new type of unloading structure, which should combine the force of rigid unloading with the edge holding effect of elastic unloading to adapt to a wider range of material thicknesses and improve the overall quality of the workpiece. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a blanking and unloading die that can effectively unload materials and improve the flatness of workpieces.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A punching and unloading die comprises an upper die base and a lower die base, wherein the lower end of the upper die base is connected to a punch fixing plate, the upper end of the lower die base is provided with a die, a punch is fixedly provided at a center position between the punch fixing plate and the die, and pressure springs are arranged at both ends of the punch fixing plate; the upper ends of the pressure springs are fixedly connected to the punch fixing plate, and the lower ends thereof are fixedly connected to a unloading plate; a die is fixedly arranged below the unloading plate, the punch moves downward to punch out the sheet material on the die, and the unloading plate presses the edge of the sheet material and unloads it; a die hole is arranged between the lower die base, the die and the unloading plate, and the punch passes through the die hole in a working state; the punching and unloading process is completed with the cooperation of the punch, the die and the unloading plate.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Please refer to Figure 1 As shown, it can be seen from the figure that the utility model is a punching and unloading die, a punching and unloading die, comprising an upper die base 1 and a lower die base 2, the lower end of the upper die base 1 is connected with a punch fixing plate 4, the upper end of the lower die base 2 is installed with a die 8, a punch 7 is fixedly installed at the center position between the punch fixing plate 4 and the die 8, and pressure springs 10 are arranged at both ends of the punch fixing plate 4; the upper ends of the pressure springs 10 are fixedly connected to the punch fixing plate 4, and the lower ends thereof are fixedly connected with a unloading plate 12; a die 8 is fixedly arranged below the unloading plate 12, the punch 7 moves downward to punch out the sheet material 13 on the die 8, and the unloading plate 12 presses and unloads the sheet material 13; a die hole 9 is arranged between the lower die base 2, the die 8 and the unloading plate 12, and the punch 7 passes through the die hole 9 in the working state; the punching and unloading process is completed with the cooperation of the punch 7, the die 8 and the unloading plate 12.

[0021] The die hole 9 is connected with the inner diameter hole of the die 8. When the upper die base 1 is pressed downward, the punch 7 vertically punches the sheet material 13 on the die 8 to punch out the product, and the product falls out of the die hole 9; then the upper die base 1 drives the punch 7 to lift upward, so that the sheet material 13 stuck on the punch 7 also moves upward synchronously, and at the same time contacts the unloading plates 12 on both sides of the punch 7, and uses the relative elastic potential energy of the pressure spring 10 to prevent the sheet material 13 from moving upward, and the corresponding unloading effect can be achieved according to the different thickness of the sheet material 13 pressed down.

[0022] like Figure 1 As shown, guide pillars 11 are connected on both sides between the upper die base 1 and the lower die base 2, and a guide sleeve 6 is provided at the connection of the upper die base 1. The upper die base 1 is slidably connected through the guide sleeve 6 and slides up and down along the guide pillars 11, which has a certain guiding function, so that the punch 7 and the unloading plate 12 can move up and down more smoothly, and the sheet material 13 on the die 8 can be accurately punched to ensure the quality and dimensional accuracy of the product.

[0023] like Figure 1 As shown, both ends of the punch fixing plate 4 are connected to the upper die base 1 by bolts 5, a punch 7 is arranged in the middle, the upper ends of the pressure springs 10 are fixedly connected to the punch fixing plate 4, and the lower ends thereof are fixedly connected to the unloading plate 12, which plays a certain elastic unloading role.

[0024] like Figure 1As shown, a die handle 3 is embedded on the upper die base 1. The die handle 3 controls the opening and closing of the die to ensure the dimensional accuracy of the product during the processing and avoid problems such as product deformation and distortion. At the same time, the die handle 3 can improve the stability of the die blanking during operation and avoid the vibration and deformation generated during the processing from affecting the quality of the product.

[0025] The working principle of this utility model:

[0026] When the mold is closed, the upper mold base 1 moves downward, and the pressure spring 10 applies pressure to the stripper plate 12, so that the stripper plate 12 plays the role of pressing the edge during the stamping process, that is, it plays the role of a press plate. During the downward movement of the mold, the pressure spring 10 and the stripper plate 12 are both in a compressed state, pressing the two sides of the sheet 13. At the same time, the punch 7 performs a punching action downward to punch out the sheet 13 into a prefabricated product of appropriate size, and then the product falls out along the inner diameter hole of the die 8 to the die hole 9.

[0027] When the mold is opened, during the upward movement of the upper die seat 1, the compression spring 10 expands and contracts to drive the stripper plate 12 to lift, and the punch 7 moves upward with the upper die seat 1, gradually separating from the sheet 13, and driving the sheet 13 to move synchronously upward to the stripper plate 12, the stripper plate 12 will block the sheet 13 from moving upward, thereby achieving the purpose of unloading. The thickness of the stripper plate 12 is also related to the thickness of the blanking sheet 13. The stripper plate 12 can be set according to the sheet 13 of different thicknesses. Under the relative action of the stripper plate 12 and the compression spring 10, the elastic potential energy of the compression spring 10 is utilized to give play to the advantages of rigid unloading and elastic unloading, so that the unloading force and product flatness are guaranteed.

[0028] The implementation modes of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
