      Description

      1. The main machine base is fabricated from welded national standard 300/150-H type steel, with a 16mm thick steel plate on top. It is then machined using a gantry milling machine, ensuring flatness of the base while eliminating internal stress. The interior is coated with anti-rust paint to prevent rust and cracking in a humid environment.
      2. The open-and-close die frame is precision machined from 45# steel plates through multiple processing steps, ensuring surface flatness and accuracy. It is assembled according to mold assembly procedures.
      3. The punch and lower die plate of the stamping die are made from national standard Gr 12mov material, forged to high density, then vacuum heat-treated, followed by wire cutting, and finally assembled. The die can switch freely between single and double row without the need to remove the mold externally.
      4. The positioning bushing is made of bearing steel through forging and lathe processing, followed by vacuum heat treatment and precise grinding. It has high concentricity and strong wear resistance. Both sides of the adjustment base are synchronously adjustable with high precision and minimal deviation. The mold measurement positioning bar ensures that the mold size remains unchanged with each replacement, and the replacement can be completed within five minutes.
      5. The conveyor shaft is made of 45# cylindrical steel, roughly processed on the lathe and precisely ground on the external cylindrical grinder to ensure concentricity and accurate positioning.
      6. The hydraulic pump station system is developed and designed using Taiwanese technology, equipped with dual 7.5KW motors driving independent oil pumps, along with dual-power air cooling. The external oil pipes have anti-wear sleeves to prevent damage caused by fatigue wear, ensuring the stability and service life of the hydraulic system. The appearance is aesthetically pleasing with zero space occupation.
      7. The hydraulic cylinder uses a specially designated high-pressure thick-walled cylinder with excellent sealing, high load capacity, low noise, and long service life.
      8. The motor is a Taiwan joint-venture Shanghai Ruijin brand reducer. The punching machine has a dedicated distribution box, custom-designed specifically for Yiping Machinery. The positioning bushing is made of bearing steel through forging and lathe processing, followed by vacuum heat treatment and precise grinding. It has high concentricity and strong wear resistance. Both sides of the adjustment base are synchronously adjustable with high precision and minimal deviation. The mold measurement positioning bar ensures that the mold size remains unchanged with each replacement, and the replacement can be completed within five minutes.
