Description

Technical Field

[0001] This utility model belongs to the field of waste chip cleaning mold technology, and in particular relates to a stamping mold that facilitates waste chip cleaning. Background Technology

[0002] During the stamping of ferromagnetic parts, the stamping stress during mold closing causes friction between the parts and mold components, leaving ferromagnetic debris. This debris tends to accumulate inside the die cavity, and as the accumulation increases, it threatens product quality and safety. Therefore, existing stamping dies generally require regular cleaning or air blowing to remove debris. However, because the debris particles adhere to the inner surface of the die cavity, cleaning or air blowing cannot completely remove the debris, leaving some residue and resulting in incomplete cleaning. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a stamping die that is easy to clean up waste. By using magnetic attraction and magnetic transfer, it ensures the thoroughness and efficiency of removing ferromagnetic waste from the die cavity, making the die processing safer and more reliable.

[0004] Technical Solution: To achieve the above objectives, this utility model provides a stamping die for easy cleaning of waste chips, comprising an upper stamping die base and a lower stamping die base. A punch is provided on the upper stamping die base, and a die is provided on the lower stamping die base. A chip-removing magnetic chuck is provided on the side of the upper stamping die base via a swing arm. The chip-removing magnetic chuck moves between the inside and outside of the stamping die by swinging the swing arm. When the chip-removing magnetic chuck moves to a position inside the stamping die corresponding to the die, it can follow the upper stamping die base downward and extend into the die to magnetically remove ferromagnetic waste chips adhering to the inner surface of the die.

[0005] Furthermore, the arm root of the swing arm has an arm shaft, which is mounted on the side of the upper stamping die holder via a bearing seat.

[0006] Furthermore, it includes a swing arm drive unit that provides a swing driving force to the swing arm, the swing arm drive unit being connected to the arm shaft drive.

[0007] Furthermore, the swing arm is arranged horizontally, the arm shaft is arranged vertically, and the swing arm swings in a fan shape at a height lower than the horizontal plane of the punch.

[0008] Furthermore, when the chip removal magnetic accumulator moves to the position corresponding to the die cavity, the chip removal magnetic accumulator is located directly above the die cavity.

[0009] Furthermore, the debris-removing magnetic accumulator is an electromagnet formed by the power supply module when energized.

[0010] Furthermore, a chip-collecting permanent magnet is also provided corresponding to the chip-removing magnetic accumulator. When the chip-removing magnetic accumulator moves to a position outside the stamping die and corresponding to the chip-collecting permanent magnet, the chip-removing magnetic accumulator is de-energized and demagnetized so that the ferromagnetic waste chips are transferred by the magnetic attraction of the chip-collecting permanent magnet.

[0011] Furthermore, the chip-collecting permanent magnet is mounted on the side of the stamping die holder via a bracket; the chip-clearing magnetic chuck, which moves between the inside and outside of the stamping die by swinging its arm, adjusts the correspondence between the die and the chip-collecting permanent magnet.

[0012] Furthermore, the height of the chip removal magnetic accumulator is greater than the depth of the die cavity.

[0013] Beneficial effects: This utility model uses a chip-removing magnetic chuck that extends into the die cavity to remove ferromagnetic debris adhering to the inner surface of the die cavity, avoiding residue of ferromagnetic debris and ensuring thorough and efficient removal of ferromagnetic debris. Moreover, when chip removal is not required, the chip-removing magnetic chuck moves to the outside of the stamping die by swinging the arm, without affecting the normal stamping operation. When chip removal is required, it will switch positions to the inside of the stamping die, and then use the liftable upper stamping die base to extend into the die cavity. There is no need to provide an additional lifting mechanism, which saves costs. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the overall structure of the present invention. Figure 1 ;

[0015] Figure 2 This is a schematic diagram of the overall structure of the present invention. Figure 2 . Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2As shown, a stamping die for easy cleaning of waste chips includes an upper stamping die base 1 and a lower stamping die base 2. A punch 3 is provided on the upper stamping die base 1, and a die 4 is provided on the lower stamping die base 2. The upper stamping die base 1 is characterized by having a chip removal magnetic 6 provided on its side via a swing arm 5. The chip removal magnetic 6 moves between the inside and outside of the stamping die by swinging the swing arm 5. When the chip removal magnetic 6 moves to a position inside the stamping die corresponding to the die 4, it can follow the upper stamping die base 1 downward and extend into the die 4 to magnetically remove ferromagnetic waste chips attached to the inner surface of the die 4. This invention utilizes a chip-removing magnetic 6 that extends into the die cavity 4 to remove ferromagnetic debris adhering to the inner surface of the die cavity 4, preventing ferromagnetic debris residue and ensuring thorough and efficient removal. When chip removal is not required, the chip-removing magnetic 6 swings to the outside of the stamping die via the swing arm 5, without affecting the normal stamping operation. When chip removal is needed, it repositions itself inside the stamping die, and then extends into the die cavity 4 using the liftable upper stamping die holder 1, eliminating the need for an additional lifting mechanism and saving costs.

[0018] More specifically, the arm root of the swing arm 5 has an arm shaft 7, which is mounted on the side of the upper stamping die holder 1 via a bearing 8. This invention includes a swing arm drive unit 9 that provides swing driving force to the swing arm 5. The swing arm drive unit 9 is drivenly connected to the arm shaft 7, and preferably a servo motor.

[0019] The swing arm 5 is arranged horizontally, and the arm shaft 7 is arranged vertically. The swing arm 5 swings in a fan shape at a height lower than the horizontal plane of the punch 3, which can avoid the punch 3 from hindering the swing of the swing arm 5.

[0020] In order to allow the chip removal magnetic 6 to enter the cavity mold 4 more effectively, in this invention, when the chip removal magnetic 6 moves to the corresponding position of the cavity mold 4, the chip removal magnetic 6 is located directly above the cavity mold 4.

[0021] The chip-removing magnetic chuck 6 is an electromagnet formed by the power supply module 10 when energized. A chip-collecting permanent magnet 11 is also provided corresponding to the chip-removing magnetic chuck 6. When the chip-removing magnetic chuck 6 moves to a position outside the stamping die and corresponding to the chip-collecting permanent magnet 11, the chip-removing magnetic chuck 6 is de-energized and demagnetized, allowing the ferromagnetic waste chips to be magnetically transferred by the chip-collecting permanent magnet 11. The chip-collecting permanent magnet 11 is mounted on the side of the stamping die base 2 via a bracket 12; the chip-removing magnetic chuck 6, whose position changes between the inside and outside of the stamping die by the swing arm 5, adjusts the correspondence between the chip-removing magnetic chuck 6 and the chip-collecting permanent magnet 11 relative to the die cavity 4. This invention not only removes ferromagnetic debris from the die cavity 4 by magnetic attraction, but also achieves the transfer of ferromagnetic debris through the structural design of the cleaning magnetic 6 (which is an electromagnet and the collecting permanent magnet 11). This keeps the cleaning magnetic 6 clean, facilitating the next cleaning operation and ensuring the thoroughness and efficiency of removing ferromagnetic debris from the die cavity 4, making the mold processing safer and more reliable.

[0022] The chip collecting permanent magnet 11 is connected to an installation rod 17, which, together with a nut, mounts the chip collecting permanent magnet 11 onto the swing arm 5.

[0023] The power supply module 10 includes a wire 13, a power supply 14, and a switch 15. The wire 13 is spirally wound around the chip removal magnet 6 and then connected to the power supply 14 mounted on the swing arm 5 via the switch 15. To bundle the wire 13, the mounting rod 17 is equipped with a wire bundling clamp. The wire bundling clamp consists of two structural halves connected by bolts and nuts. Both structural halves have wire grooves. After the two structural halves are spliced ​​together to form the wire bundling clamp, the wire 13 is bound by the closed wire grooves.

[0024] In order to facilitate the transfer of ferromagnetic waste from the cleaning magnetic accumulator 6 to the collecting permanent magnet 11, when the cleaning magnetic accumulator 6 magnetically attracts the ferromagnetic waste in the concave mold 4, the ferromagnetic waste should not be magnetically attracted to the top surface of the cleaning magnetic accumulator 6. Therefore, the height of the cleaning magnetic accumulator 6 is greater than the depth of the concave mold 4, so that the magnetically attracted ferromagnetic waste is distributed on the side and bottom surfaces of the cleaning magnetic accumulator 6.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
