Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies, and in particular relates to a small hole anti-jump waste structure. Background Art

[0002] When stamping hardware molds, the characteristics of certain materials may cause waste material to jump during stamping. For example, materials that are too hard or too brittle are prone to produce debris and are difficult to discharge completely. If the stamping parameters are set improperly, such as too large a stroke, too fast a punch speed, or too much deflection of the punch press, the waste material may jump due to instability during the stamping process. The above problems will cause waste material to jump when punching small holes.

[0003] When the small holes are punched, waste material jumps out, which can easily cause product damage. The jumping of waste material may cause uneven product surface or quality problems such as scratches and scrapes, affecting the appearance and service life of the product. The jumping of waste material will cause unstable factors in the production process, increase the time cost of waste treatment and cleaning, and reduce production efficiency. The jumping of waste material may cause product quality to be unqualified, requiring additional processing or re-production, increasing manufacturing costs. The unstable product quality due to the jumping of waste material may affect customer satisfaction with the product and reduce brand reputation. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model proposes a small hole anti-jump waste structure.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A small hole anti-jump waste structure comprises a lower die entry block and a lower die plate, the lower die entry block is provided with a lower die blade for cooperating with a punch to punch a product and a hole expansion guide hole located below the lower die blade; the lower die plate is fixedly sleeved on the outer side of the lower die entry block, and the lower die plate is provided with an air pipe connected to an air suction groove on the side of the lower die entry block;

[0007] The air pipe is connected with the air suction groove. When the air pipe is working, the lower die blade and the expansion guide hole are vacuumed, so that the waste is taken out in the flow of air to achieve the purpose of preventing waste from jumping out.

[0008] Preferably, a lower pad is fixed to the bottom of the lower die block and the lower die plate, and a waste material discharge hole connected to the expansion guide hole is opened on the lower pad, so that the waste material can be discharged smoothly from the die during or after the stamping process.

[0009] Preferably, the suction groove is V-shaped or U-shaped. The V-shaped or U-shaped suction groove can enhance the adsorption effect and ensure that the waste can be effectively adsorbed and discharged smoothly.

[0010] Preferably, the end of the air pipe away from the suction groove is connected to an air connection head, and the air connection head is connected to a vacuum pump or other negative pressure device through a pipeline. Connecting a vacuum pump or other negative pressure device can provide a stable vacuum gas source, ensure that the vacuum effect formed by the suction groove is sufficient and lasting, and ensure the smooth adsorption and discharge of waste.

[0011] Preferably, the diameter of the expansion guide hole increases from top to bottom, so that waste can pass through smoothly, reducing the possibility of blockage or jamming.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are:

[0013] The small hole anti-jump waste structure can form a negative pressure environment by processing a V-shaped or U-shaped suction groove on the side of the lower die block and connecting the air pipe with a vacuum pump or other negative pressure device. During the stamping process, the waste contacts the suction groove, and due to the negative pressure, the waste is adsorbed around the lower die blade and the expansion guide hole to prevent it from jumping.

[0014] The aperture of the expansion guide hole increases from top to bottom. This design can better adapt to waste of different shapes and sizes, reduce the possibility of waste blockage or jamming, and also help the waste to pass through the guide hole more smoothly to prevent waste from being retained. The setting of the waste blanking hole provides a direct discharge path for the waste. After the stamping is completed, the waste can be smoothly discharged from the mold through the blanking hole, avoiding the problem caused by the accumulation of waste inside the mold.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The following is combined with Figure 1-2 To further explain this application in detail,

[0020] The embodiment of the present application discloses a small hole anti-jump waste structure, comprising a lower die block 1 and a lower die plate 4, the lower die block 1 is provided with a lower die blade 2 for cooperating with a punch to punch a product and a hole expansion guide hole 3 located below the lower die blade 2; the lower die plate 4 is fixedly sleeved on the outer side of the lower die block 1, and the lower die plate 4 is provided with an air pipe 6 connected to an air suction groove 5 on the side of the lower die block 1;

[0021] The air pipe 6 is connected with the air suction groove 5. When the air pipe 6 is working, the lower die blade 2 and the expansion guide hole 3 are vacuumed, so that the waste is taken out in the flow of air to achieve the purpose of preventing waste from jumping out.

[0022] By forming a vacuum state between the lower die blade 2 and the expansion guide hole 3, the waste can be effectively adsorbed and smoothly taken out, thereby avoiding the situation where the waste jumps and causes product crushing. The waste jump will cause the surface quality of the product to deteriorate. By effectively preventing the waste jump, the quality of product stamping and forming can be guaranteed to be stable, and the appearance and performance of the product can be improved. Reducing the waste jump can reduce the time and cost of waste treatment, improve the efficiency of the production process, and shorten the production cycle. The waste loss caused by the waste jump will increase the production cost, and this structure can effectively adsorb and remove the waste, reduce the waste loss, and reduce the waste jump. It can not only protect the product and production equipment, but also reduce the risk of operator injury and improve the safety of the production process.

[0023] A lower pad 7 is fixed to the bottom of the lower die block 1 and the lower die plate 4, and a waste material discharge hole 8 connected to the expansion guide hole 3 is provided on the lower pad 7. The waste material discharge hole 8 can provide a direct path so that the waste material can be discharged smoothly from the die during or after the stamping process, reducing the possibility of waste material clogging or obstruction.

[0024] The air suction groove 5 is V-shaped or U-shaped. The V-shaped or U-shaped air suction groove 5 can enhance the adsorption effect and ensure that the waste can be effectively adsorbed and discharged smoothly.

[0025] The end of the air pipe 6 away from the air suction groove 5 is connected to the air connection head 9, and the air connection head 9 is connected to a vacuum pump or other negative pressure device through a pipeline. Connecting a vacuum pump or other negative pressure device can provide a stable vacuum air source, ensure that the vacuum effect formed by the air suction groove 5 is sufficient and lasting, and ensure the smooth adsorption and discharge of waste. By connecting a vacuum pump or a negative pressure device, the negative pressure size and working time can be flexibly adjusted to achieve efficient energy utilization and reduce energy waste. Connecting a vacuum pump or other negative pressure device can achieve automatic control and adjustment, improve the degree of automation of production, and can adjust parameters according to actual needs to improve work efficiency.

[0026] The aperture of the expansion guide hole 3 increases from top to bottom. The aperture gradually increases from top to bottom to better adapt to waste materials of different shapes and sizes, so that the waste materials can pass smoothly, reducing the possibility of blockage or jamming. The gradually increasing aperture can reduce the resistance of the waste materials when passing through the expansion guide hole 3, improve the fluidity and smoothness of the waste materials, and reduce the possibility of the waste materials being blocked or retained. The design of gradually increasing aperture can make the waste materials more stable during the flow process, avoid the instability caused by material blockage, and ensure the smooth discharge of the waste materials.

[0027] The small hole anti-jump waste structure effectively prevents waste from jumping through designs such as the suction groove 5 and vacuum adsorption, the hole expansion guide hole 3, the waste drop hole 8 and negative pressure control, thereby ensuring the stable quality of product stamping and improving production efficiency and safety.
