[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method in which pressure is applied to materials at room temperature using dies mounted on a press, causing them to separate or plastically deform, thereby obtaining the desired parts. Soft magnetic powder needs to be pressed and formed by stamping dies in conjunction with a stamping press during the production process, and requires the use of a special stamping head for stamping operations.

[0003] However, existing methods for stamping soft magnetic powders present the following problems: Different specifications and shapes of soft magnetic products often require different stamping heads during the stamping process. Therefore, it is sometimes necessary to replace the stamping head. Current methods require operators to use specialized tools for disassembly and replacement, which is cumbersome and lacks a quick replacement method. Therefore, a corresponding technical solution needs to be designed to address these problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a soft magnetic iron-silicon-aluminum stamping die for easy and quick replacement of the stamping head, including a stamping machine 1, an operating platform 2 on the stamping machine 1, a stamping die 3 placed on the operating platform 2, a quick-change assembly 4 installed at the power output end of the stamping machine 1, a stamping head 16 installed at the bottom of the quick-change assembly 4, the quick-change assembly 4 including a fixing collar 5 and a mounting base 6 fixed below the fixing collar 5, the fixing collar 5 being fixed to the power output end of the stamping machine 1 and having a clamp 7 inside, and a sliding section longitudinally formed on the fixing collar 5. The groove 8 has several sets of limiting holes 9 longitudinally opened on both sides. A slide rod 10 is slidably arranged in the groove 8. The inner end of the slide rod 10 is connected to the clamp 7. The clamp 7 includes two sets of arc-shaped clamping plates 11 arranged symmetrically and a floating ball 12 located between the two sets of arc-shaped clamping plates 11. The lower end of the arc-shaped clamping plate 11 is inserted into the mounting base 6 and the middle part is rotatably installed on the inner wall of the fixed collar 5 through a pin. The outer side of the floating ball 12 is connected to the slide rod 10. The upper end of the punch head 16 is inserted into the mounting base 6. The inner sides of the two sets of arc-shaped clamping plates 11 are clamped on both sides of the punch head 16.

[0019] Further improvements, such as Figure 2As shown, a disc 13 is fixed in the middle of the slide bar 10. Limiting bolts 14 are inserted on both sides of the disc 13. The inner end of the limiting bolt 14 is inserted into the limiting hole 9. By inserting the limiting bolt 14 into the corresponding limiting hole 9, the slide bar 10 and the floating ball 12 can be positioned and fixed.

[0020] Further improvements, such as Figure 3 As shown, the arc-shaped clamp 11 has an arc-shaped structure and an outward-convex arc surface structure in the middle, which facilitates the rotation and adjustment of the arc-shaped clamp 11.

[0021] Further improvements, such as Figure 3 As shown, the lower end of the arc-shaped clamping plate 11 is formed with several sets of biting teeth 15. The two adjacent sets of biting teeth 15 are equidistantly distributed and abut against the stamping head 16, which improves the clamping stability of the upper end of the stamping head 16.

[0022] Specifically, the floating ball 12 has a spherical structure and its surface is in contact with the inner side of the arc-shaped clamping plate 11. The diameter of the floating ball 12 is smaller than the inner cavity of the fixed collar 5. The floating ball 12 can act on the arc-shaped clamping plate 11 during the up-and-down floating process, which can realize the rotation adjustment of the arc-shaped clamping plate 11 and facilitate the clamping and fixing of the punching head 16.

[0023] In use: When the punch head 16 needs to be replaced, the operator can pull out the limit bolt 14 and hold the slide bar 10 to move it downward along the slide groove 8. During the movement, the arc-shaped clamping plate 11 can rotate freely to unlock and loosen the punch head 16. At this time, the operator can disassemble the punch head 16 and insert the punch head 16 to be replaced into the mounting base 6. Then, the operator holds the slide bar 10 to drive the floating ball 12 upward. During the movement, the floating ball 12 acts on the arc-shaped clamping plate 11, causing the upper end of the arc-shaped clamping plate 11 to flip outward and the lower end to flip inward, so that the arc-shaped clamping plate 11 clamps and fixes the upper end of the punch head 16. After clamping and fixing, the limit bolt 14 can be reinserted into the corresponding limit hole 9 to fix it. The operation is simple and does not require disassembly or assembly tools.
