Technical Field
[0001] This utility model relates to the field of drilling tooling technology, and in particular to drilling mold plates and drilling components. Background Technology
[0002] High-speed train locomotives often generate significant noise during operation. Therefore, during the manufacturing process of high-speed train locomotives, it is necessary to install several sound-permeable holes on the bottom perforated plate to help the noise generated by internal equipment or devices leak out. The sound-permeable plate is roughly fan-shaped, with an arc-shaped bottom (narrow end) and a wave-like top to adapt to the locomotive's shape. The sound-permeable holes on the plate are arranged according to a certain rule.
[0003] The material of high-speed train heads is generally fiberglass. When processing these holes using existing technology, it is usually done manually one by one with an electric drill. The manual drilling method makes it difficult to control the spacing between holes, the orientation of the holes is also difficult to control, the operation is difficult, the drilling is difficult, and it is difficult to produce regular holes.
[0004] Therefore, in view of the shortcomings of the above-mentioned solution in actual production and implementation, it has been modified and improved. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, we have specially provided a punching mold plate and punching components to solve the technical problems of difficult and difficult punching operation on high-speed train heads.

With the help of this die plate, the sound-permeable perforated plate can be accurately punched. The hole position is fixed, which reduces the difficulty of operation and solves the technical problems of difficult and difficult drilling operation on high-speed train heads. In addition, the presence of the steel sleeve makes the die plate more wear-resistant and durable, and improves its service life.
