Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die with internal tooth shape. Background Technology

[0002] In current industrial production, the machining of complex shapes such as punch teeth and polygons usually relies on CNC lathes. While this machining method meets production needs to some extent, it has many problems and limitations.

[0003] During the stamping process on a CNC lathe, due to design limitations, there is often insufficient space to discharge excess waste material after it is punched in. This leads to the accumulation of waste material in the processing area, which not only affects processing efficiency but may also damage processing accuracy and the equipment itself. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a punching internal tooth-shaped die, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a punching tooth mold, including a punching tooth upper mold and a punching tooth pin, wherein a punching tooth channel is provided through the interior of the punching tooth upper mold, and a waste discharge port communicating with the punching tooth channel is provided through the bottom, and the top of the punching tooth pin is integrally connected to the punching tooth head.

[0006] Furthermore, the shape of the punch head is adapted to the shape of the punch channel, and the punch needle includes a coarse needle rod and a fine needle rod. The coarse needle rod is located at the lower part of the fine needle rod, and the fine needle rod is integrally connected to the punch head. A boss is provided at the connection between the coarse needle rod and the fine needle rod.

[0007] Furthermore, the upper die of the punch is installed on the punching drive end of the stamping machine, and the bottom of the punch needle is fixed in the die clamp.

[0008] Furthermore, the shape of the punch channel and the punch head can be set to a tooth shape or a polygon as required.

[0009] Furthermore, during the stamping process, the boss can support the product and prevent it from moving further down once it reaches its lowest position.

[0010] Furthermore, during the downward pressing of the upper die of the punch, both the punch head and the fine needle rod will enter the interior of the punch channel.

[0011] This utility model provides a punching die with internal toothed profiles. Compared with the prior art, it has the following advantages:

[0012] This internal toothed die has a waste discharge port in the upper die that is connected to the punch channel. During the stamping process, the waste generated will be pushed to the waste discharge port by the punch head and removed from the waste discharge port, thus solving the problem of waste accumulation and affecting stamping efficiency.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a punching tooth mold, mainly composed of a punching tooth upper mold 1 and a punching tooth needle 2, wherein a punching tooth channel 12 is provided through the interior of the punching tooth upper mold 1, and a waste discharge port 11 is provided through the bottom of the punching tooth upper mold 1, the waste discharge port 11 is connected to the punching tooth channel 12, and the top of the punching tooth needle 2 is integrally connected to the punching tooth head 21.

[0020] The upper die 1 of the punch is installed on the punching drive end of the punching machine, and the bottom of the punch needle 2 is fixed in the die clamp. The punching drive end of the punching machine and the die clamp are not shown in the figure, and are both existing known technologies, which will not be described in detail here.

[0021] The shapes of the punch channel 12 and the punch head 21 are adapted to each other, for example, they can be set to tooth shape or polygon as required;

[0022] The punch needle 2 consists of two different needle rods, one thick and one thin, connected together. The thick needle rod is located below the thin needle rod. The punch head 21 is connected to the upper thin needle rod. A boss 22 is provided at the connection between the thick needle rod and the thin needle rod. During the punching process, the boss 22 can support the product and prevent it from moving further down when the product reaches the lowest position.

[0023] During the downward pressing of the upper die 1, both the punch head 21 and the fine needle rod will enter the interior of the punch channel 12;

[0024] During use, the product 3 is placed on the upper part of the punch needle 2. Then, the upper punch die 1 moves downward to punch the product 3. During the punching process, the product 3 moves downward synchronously due to the downward pressure of the upper punch die 1. As the product 3 moves downward, the corresponding punch head 21 inside it will push the center part of the product 3 upward, which is the waste. When the waste is pushed into the waste discharge port 11, the upper punch die 1 stops moving downward. At this time, the center of the product 3 will also be punched with a tooth shape or polygon according to the shape of the punch head 21. Then, the waste in the waste discharge port 11 is removed, and the punched product 3 is removed.
