Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a stamping equipment for the production of precision metal products. Background Technology

[0002] Stamping equipment is a device that uses a press and dies to apply external force to metal sheets, strips, tubes, etc., causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. It is an important tool for metal processing in industrial production.

[0003] Stamping equipment mainly uses the pressing between the moving die and the fixed die to extrude metal sheets into the same shape as the die cavity. During this process, the stamping cavity places the metal sheet in a designated position between the fixed die and the moving die to ensure the accuracy of stamping. However, for stamping equipment with manual feeding, if there is no feeding and positioning structure, the feeding position cannot be guaranteed to be in the accurate position every time. Therefore, it is impossible to guarantee the accurate stamping of metal products, which will result in more defective products. Utility Model Content

[0004] The purpose of this invention is to provide a precision metal product stamping equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a fixed mold, a moving mold, and a positioning frame. The positioning frame is disposed between the fixed mold and the moving mold. The four bottom corners of the positioning frame are equipped with push rods via disassembly and assembly components. The bottom of the push rods is slidably connected to the fixed mold. The positioning frame has a U-shaped structure and is provided with positioning grooves inside that are the same as the shape of the stamped sheet. The bottom of the moving mold is equipped with push rods at positions corresponding to the four corners of the positioning frame. The upper end of the moving mold is provided with a U-shaped groove at a position corresponding to the positioning frame.

[0006] Preferably, an ejector groove is provided in the fixed mold at a position corresponding to the ejector pin, and a lightweight spring is fixed between the bottom of the ejector groove and the bottom of the ejector pin.

[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 1-4This utility model provides a technical solution: including a fixed mold 1, a moving mold 2 and a positioning frame 3. The positioning frame 3 is disposed between the fixed mold 1 and the moving mold 2. The bottom four corners of the positioning frame 3 are equipped with push rods 4 through disassembly and assembly components. The bottom of the push rods 4 is slidably connected to the fixed mold 1. The positioning frame 3 has a U-shaped structure and is provided with a positioning groove 31 with the same shape as the stamping sheet inside. The bottom of the moving mold 2 is equipped with push rods 5 at positions corresponding to the four corners of the positioning frame 3. The upper end of the moving mold 2 is provided with a U-shaped groove 11 at a position corresponding to the positioning frame 3.

[0019] An ejector groove 12 is provided in the fixed mold 1 at a position corresponding to the ejector pin 4. A light spring 13 is fixed between the bottom of the ejector groove 12 and the bottom of the ejector pin 4. An upper groove 51 is provided in the moving mold 2 at a position corresponding to the push rod 5. A strong spring 52 is fixed between the top of the upper groove 51 and the top of the push rod 5. Guide holes 14 are provided at the four corners of the fixed mold 1. Guide rods 21 are fixed at the four corners of the moving mold 2. A sliding ring 22 is slidably connected to the guide rod 21. A buffer spring 23 is fixed between the sliding ring 22 and the moving mold 2.

[0020] The assembly and disassembly components include a rod 42 and a locking block 33. An end plate 41 is fixed to the upper end of the top rod 4, and the rod 42 is fixed to the upper end of the end plate 41. An outer groove 43 is provided on the outer side of the rod 42. Slots that are compatible with the rod 42 are provided at the four corners of the bottom of the positioning frame 3. The locking block 33 is installed on the side wall of the slot and is aligned with the outer groove 43. The end of the locking block 33 is inserted into the outer groove 43. A drive groove 32 is provided on the side wall of the slot and at the corresponding position of the locking block 33. A threaded rod 34 is rotatably connected in the drive groove 32. One end of the threaded rod 34 is threaded into the locking block 33. A knob 35 is fixed to the outer end of the threaded rod 34. A groove is provided on the outer side of the positioning frame 3 and at the corresponding position of the knob 35. The knob 35 is located in the groove.

[0021] Working principle: Before the moving die 2 presses down, the stamping sheet can be placed in the positioning groove 31. Since the shape of the positioning groove 31 is adapted to the size of the feeding sheet, the accurate position of the metal sheet between the fixed die 1 and the moving die 2 can be guaranteed. Then, during the pressing down, the push rod 5 will push the positioning frame 3 downward, so that it gradually enters the return groove 11. At this time, the light spring 13 will be compressed. During the continuous pressing down, until it is completely pressed, the push rod 5 will squeeze the strong spring 52 and store it in the upper groove 51 without affecting the normal stamping. In operation, after the mold is opened, the lightweight spring 13 and the ejector rod 4 will push out the positioning frame 3 to proceed with the next part processing operation. When the shape of the stamped sheet changes, the positioning frame 3 with the same positioning groove 31 can be replaced. During the replacement process, the rotation of the knob 35 can drive the threaded rod 34 to rotate, thereby driving the locking block 33 to extend and retract. When the locking block 33 is pulled out from the outer groove 43, the disassembly operation can be completed quickly. At the same time, after the positioning frame 3 is installed, the locking block 33 can be inserted into the outer groove 43 to fix the positioning frame 3.
