Description

Technical Field

[0001] The present application relates to the technical field of stamping dies, and in particular to a new type of high-precision stamping die. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] The high-precision stamping dies used for hardware parts require frequent maintenance. The stamping dies need to be rust-proofed and the die holes cleaned to maintain high-precision conditions. However, traditional high-precision dies cannot be used normally during rust-proofing and cleaning, and the dies need to be removed from the stamping machine before cleaning, which is extremely inconvenient. Utility Model Content

[0004] In order to solve the problem, the present application provides a new type of high-precision stamping die.

[0005] The present application provides a new type of high-precision stamping die adopts the following technical solution:

[0006] A new type of high-precision stamping die comprises a lower base and an upper base, wherein a support plate is fixed on the lower base; a male die is fixed on the upper base; a plurality of female die are connected to the support plate, and the female die is matched with the male die.

[0007] Preferably, a plurality of fixing holes are provided on the upper base.

[0008] Preferably, a plurality of U-shaped holes are provided on the lower base, and the U-shaped holes are matched with the fixing holes.

[0009] Preferably, a plurality of screws are fixed on the top of the support plate, nuts are screwed onto the screws, a plurality of the concave molds are provided with round holes sleeved on the screws, and the plurality of the concave molds are stacked on top of each other.

[0010] Preferably, the nut is connected to the female mold.

[0011] Preferably, a plurality of sleeve holes are provided on the male mold, the sleeve holes correspond to the nuts, and the diameters of the sleeve holes are larger than those of the nuts.

[0012] Preferably, a chamfer is provided at the notch of the sleeve hole.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By setting up multiple stacked concave dies, multiple concave dies are limited and fixed by screws and nuts. When one of the concave dies needs to be rust-proofed or cleaned, the nut can be screwed to disassemble it, and then the nut can be used to fix the other concave dies. This ensures that the concave dies can perform stamping work normally when being cleaned, thereby improving work efficiency and avoiding the traditional step of requiring staff to disassemble the mold as a whole, reducing manpower consumption and improving practicality.

[0019] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0020] The present application embodiment discloses a new type of high-precision stamping die. Figure 1-Figure 3A high-precision new stamping die comprises a lower base 1 and an upper base 4, a support plate 2 is fixed on the lower base 1; a convex die 5 is fixed on the upper base 4; a plurality of concave dies 3 are connected to the support plate 2, the concave dies 3 are adapted to the convex die 5, a plurality of fixing holes 7 are provided on the upper base 4, a plurality of U-shaped holes 6 are provided on the lower base 1, the U-shaped holes 6 are adapted to the fixing holes 7, a plurality of screws 8 are fixed on the top of the support plate 2, a nut 9 is screwed on the screw 8, a plurality of concave dies 3 are provided with round holes sleeved on the screw 8, a plurality of concave dies 3 are stacked on each other, the nut 9 is connected to the concave dies 3, when in use, when the concave dies 3 at the top need to be cleaned, they are screwed separately After unscrewing the disassembly nut 9 and removing the female mold 3, the fixing nuts 9 are respectively screwed to limit and fix the other female molds 3. At this time, starting the punching machine can still make the male mold 5 punch on the female mold 3 to realize the punching function. By setting a plurality of stacked female molds 3, the plurality of female molds 3 are limited and fixed by screws 8 and nuts 9. When one of the female molds 3 needs to be rust-proofed or cleaned, the nut 9 can be screwed to disassemble it, and then the nut 9 can be used to fix the other female molds 3, so that the female mold 3 can perform stamping work normally during cleaning, thereby improving work efficiency and avoiding the traditional step of requiring staff to disassemble the mold as a whole, reducing manpower consumption and improving practicality.

[0021] In this embodiment, if Figure 1 and Figure 2 As shown, a plurality of sleeve holes 10 are provided on the male mold 5, the sleeve holes 10 correspond to the nuts 9, and the diameter of the sleeve holes 10 is larger than the nuts 9. The male mold 5 and the female mold 3 fit together to achieve a stamping effect, and the setting of the sleeve holes 10 can prevent the nuts 9 from obstructing the fitting of the male mold 5 and the female mold 3, which is practical.

[0022] In this embodiment, if Figure 2 As shown, a chamfer is provided at the notch of the sleeve hole 10. The chamfer reduces the friction coefficient, facilitates the sleeve hole 10 to be more smoothly sleeved on the nut 9, and improves the stability of the two molds when they are pressed together.

[0023] The implementation principle of a new type of high-precision stamping mold in the embodiment of the present application is as follows: when in use, when the concave mold 3 located at the top needs to be cleaned, the disassembly nuts 9 are screwed and removed respectively. After removing the concave mold 3, the fixing nuts 9 are screwed and fixed respectively, so that the other concave molds 3 can be limited and fixed. At this time, starting the punching machine can still make the male mold 5 punch on the concave mold 3 to realize the stamping function. By setting a plurality of stacked concave molds 3, the plurality of concave molds 3 are limited and fixed by screws 8 and nuts 9. When one of the concave molds 3 needs to be rust-proofed or cleaned, the nut 9 can be screwed to disassemble it, and then the nut 9 can be used to fix the other concave molds 3, so that the concave mold 3 can perform stamping work normally during cleaning, thereby improving work efficiency and avoiding the traditional step of requiring staff to disassemble the mold as a whole, reducing manpower consumption and improving practicality.
