[0002] In the field of modern metal processing and manufacturing, stamping is widely used as an efficient and low-cost processing method in the production of various metal parts. Due to the diverse shapes and sizes of metal parts, the stamping process requires precise machining of holes of different shapes, and the stamping of irregular holes poses a significant challenge to mold technology and production efficiency.

[0003] Traditional metal parts punching dies for irregular holes often present problems during production. The material unloading process has consistently been a key factor limiting production efficiency. In previous die designs, waste material after stamping often required manual cleaning and removal. This not only increased the labor intensity of workers but also easily led to chaos on the production floor, consequently affecting production efficiency and product quality. Delayed manual unloading can cause waste material to accumulate inside the die, leading to a series of quality problems such as die damage, reduced stamping accuracy, and scratches on the product surface. Furthermore, manual unloading also poses certain safety hazards; workers may suffer mechanical injuries due to improper operation. Utility Model Content

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a stamping die for irregular holes in metal parts, comprising:

[0026] The base 1 has a support frame 2 fixedly installed on its top. The support frame 2 has a cylinder 3 on its top. The output end of the cylinder 3 is connected to a mounting base 7. The bottom of the mounting base 7 has a stamping knife 8. The top of the base 1 has a stamping seat 4 fixedly installed. The stamping seat 4 has a stamping hole 5.

[0027] An automatic material discharge assembly 6 is installed inside the stamping base 4. The automatic material discharge assembly 6 includes a first telescopic rod 601. A movable base 603 is connected to the bottom of the inner cavity of the stamping base 4 by a spring component 1. A pusher plate 605 is movably sleeved on the upper rear side of the stamping base 4 and contacts the top of the movable base 603. A connecting plate 604 is fixedly installed on the rear side of the pusher plate 605. One side of the connecting plate 604 is connected to the rear side of the stamping base 4 by a spring component 2. A downward pusher plate 607 is fixedly installed on the top of the pusher plate 605. An upward pusher plate 606 is fixedly installed on the rear side of the mounting base 7. The stamping base 4 is equipped with an automatic material discharge component 6. When the cylinder 3 controls the mounting base 7 and the upper push plate 606 to move downward, the bottom of the upper push plate 606 contacts the top of the lower push plate 607, thereby pushing the lower push plate 607 and the pusher plate 605 to move away from the moving base 603, opening the top of the moving base 603. After punching, the cylinder 3 drives the upper push plate 606 to move upward, and the elastic force of the elastic component 2 makes the pusher plate 605 move towards the moving base 603, which facilitates the discharge of the punched waste material from the stamping base 4, achieving the effect of automatically discharging waste material so that the mold can be punched again next time.

[0028] The elastic component includes a first telescopic rod 601 and a first spring 602. The two ends of the first telescopic rod 601 are connected to the top of the inner cavity of the stamping seat 4 and the bottom of the movable seat 603, respectively. The first spring 602 is movably sleeved on the outer side of the first telescopic rod 601, and the two ends of the first spring 602 are connected to the movable seat 603 and the stamping seat 4, respectively. The movable seat 603 is connected to the stamping seat 4 via the first telescopic rod 601 and the first spring 602, which facilitates buffering the stamping cutter 8 when it presses down to punch a hole, preventing the stamping cutter 8 from directly pressing against the movable seat 603 and causing impact force that could damage the stamping cutter 8.

[0029] The second elastic component includes a second telescopic rod 608 and a second spring 609. The second spring 609 is sleeved on the outer side of the second telescopic rod 608. The two ends of the second telescopic rod 608 and the second spring 609 are respectively connected to the connecting plate 604 and the stamping seat 4. The second telescopic rod 608 and the second spring 609 are connected to the stamping seat 4 through the stamping seat 4, which facilitates the reset after the downward push plate 607 moves, and facilitates the collection of waste material pushed out of the moving seat 603.

[0030] The bottom inclination angle of the upward push plate 606 matches the top inclination angle of the downward push plate 607, with the upward push plate 606 located above and behind the top of the downward push plate 607. The shape and positional relationship between the upward push plate 606 and the downward push plate 607 facilitates the movement of the downward push plate 607 when the upward push plate 606 moves downward, allowing the pusher plate 605 on the top of the moving seat 603 to be moved away for temporary storage of waste materials.

[0031] A discharge channel 11 is fixedly installed on the front side of the inner cavity of the stamping base 4. The rear side of the discharge channel 11 is located on the front side of the movable base 603, and the discharge channel 11 is inclined. The discharge channel 11 on the front side of the movable base 603 facilitates the discharge of waste material after it is pushed out of the movable base 603 by the pusher plate 605, and it slides out through the discharge channel 11 and is collected in a pile for easy subsequent cleaning.

[0032] A third telescopic rod 9 is fixedly installed on both sides of the bottom of the mounting base 7. A pressing seat 12 is fixedly installed at the bottom of the third telescopic rod 9. A third spring 10 is provided on the outer side of the third telescopic rod 9. The two ends of the third spring 10 are respectively connected to the bottom of the mounting base 7 and the top of the pressing seat 12. By providing the third telescopic rod 9, the third spring 10 and the pressing seat 12 on both sides of the bottom of the mounting base 7, it is convenient to fix the two sides of the metal parts when the stamping knife 8 is punching, thus improving the stability of stamping.

[0033] The base 1 has several evenly distributed stamping seats 4 and an automatic feeding assembly 6 on its top, and each stamping seat 4 is equipped with a cylinder 3, a mounting base 7, and a stamping knife 8 above it. By having several stamping seats 4, an automatic feeding assembly 6, a cylinder 3, a mounting base 7, and a stamping knife 8 on the base 1, this device can punch multiple metal parts simultaneously, improving work efficiency.

[0034] Working principle: When using this device, place the metal part to be punched on the top of the stamping seat 4. Drive cylinder 3 controls the mounting seat 7 and the stamping knife 8 to move downward. The mounting seat 7 moves downward, taking the upper push plate 606, the third telescopic rod 9, the third spring 10 and the pressing seat 12 downward. At this time, the bottom of the upper push plate 606 and the pressing seat 12 first contact the top of the lower push plate 607 and the top of the metal part, respectively. As the mounting seat 7 moves downward, the upper push plate 606 pushes the lower push plate 607 and the pusher plate 605 to move away from the moving seat 603, removing the pusher plate 605 on the moving seat 603. At this time, the discharge channel 11 and the third spring 10 fix the metal part. As the stamping knife 8 moves downward, it contacts the metal part to achieve punching. The stamping knife 8 carries the waste material and pushes the moving seat 603 downward.

[0035] After punching, cylinder 3 drives the upper push plate 606, the third telescopic rod 9, the third spring 10 and the pressing seat 12 to move upward. The waste material stays on the top of the moving seat 603. The upper push plate 606 and the pressing seat 12 move upward. The lower push plate 607 has no pushing force limit. The elastic force of the elastic component 2 makes the push plate 605 move towards the moving seat 603, and the waste material punched out is discharged from the stamping seat 4 through the discharge channel 11, realizing automatic waste discharge.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
