Description
Technical Field
[0001] The utility model relates to the technical field of punching dies, in particular to a punching die. Background Art
[0002] As an important processing tool, punching dies are widely used in fields such as metal processing, plastic processing, and electronic product manufacturing. In industrial production, the punching process applies a certain pressure on the material through the die, causing the material to undergo plastic deformation or fracture under the action of the die, thereby forming holes of the required shape. This process has the advantages of high efficiency, precision, and high automation, and thus occupies an important position in modern manufacturing.
[0003] Although traditional punching dies perform well in many aspects, there are still some problems and limitations in practical applications: insufficient precision: traditional punching dies sometimes have difficulty meeting high - requirement manufacturing standards in terms of punching precision and consistency, especially in the processing of micro - holes and high - precision holes; poor flexibility: traditional dies are usually designed for holes of specific specifications and shapes, and it is difficult to adapt to the processing requirements of holes with different specifications and positions. This results in frequent die replacement and long adjustment times, affecting production efficiency; inconvenient waste treatment: if the waste generated during the punching process cannot be discharged in a timely and effective manner, it will accumulate in the die, affecting the normal operation of the die and the punching quality; complex maintenance: the structure of traditional dies is relatively complex, and the replacement and maintenance of components are inconvenient, increasing the downtime and maintenance costs of the equipment.

[0034] 2. Working process
[0035] Preparation work:
[0036] Before the punching operation, ensure that the material is placed on the bottom support table 31 of the lower die 3, and the position of the material needs to be aligned with the punching positions of the upper pressing table 32 and the punching needle 55.
[0037] According to the punching requirements, select the appropriate connecting plate 54 and punching needle 55 and install them on the upper die 5.
[0038] Start the punching die:
[0039] Start the pneumatic system, and the pneumatic push rod 34 presses the upper pressing table 32 downward to compact the material and fix the position of the material.
[0040] The force-applying push rod 7 starts to act, pushing the upper die 5 downward along the guide pillar 4.
