Introduction
GB/T 37912—2019 Interpretation of the national standard for CNC punching and shearing compound machines
1. Standard Overview
This standard specifies the parameters, requirements, test methods, inspection rules, marking, packaging, transportation and storage of CNC punching and shearing compound machines, and is applicable to composite processing equipment that integrates the functions of CNC rotary head presses and CNC right-angle shearing machines.
2. Comparison of standard frames
| Standard dimensions | Technical parameters | Performance requirements | Safety specifications |
|---|---|---|---|
| Nominal punching force | 200kN, 250kN, 300kN | Meet the needs of composite processing and ensure stable operation at full load | Meet the safety requirements of GB 17120 and have reliable protective devices |
| Maximum shear plate thickness | 4.0mm (carbon steel) | Support continuous step-feed shearing function | Emergency stop button configuration complies with GB/T5226.1 |
| Maximum single-time processed plate size | 1000×1500mm | With automatic positioning and waste collection functions | Power-off protection mechanism for the press to ensure safe operation |
3. Background of standard formulation and technological evolution
Background analysis:With the increasing demand for automation and efficient processing in the manufacturing industry, CNC punching and shearing machines have gradually become important equipment in the metal processing industry. This standard is formulated to regulate market and technological development and ensure product quality and safety.
Technological evolution
From traditional mechanical punching and shearing equipment to modern CNC integrated systems, it has gone through the following stages:
- Single-machine operation: Early equipment required manual adjustment of parameters, which was inefficient.
- Automation control: Introduce PLC and servo motors to improve processing accuracy.
- Compound function integration: Combine stamping and shearing functions to improve production efficiency.
4. Implementation suggestions
To ensure the effective implementation of the standard and the efficient operation of the equipment, the following suggestions are put forward:
- Equipment selection: Select appropriate specifications according to production needs and refer to the technical parameters in Table 1.
- Operation training: Conduct systematic training for operators to master safety regulations and troubleshooting.
- Regular maintenance: Inspect and lubricate the equipment according to standard requirements to extend its service life.
- Update and upgrade: Pay attention to technological progress, optimize equipment configuration in a timely manner, and improve processing efficiency.
