Equipment Positioning: A high-precision automated device specifically designed for the punching process of oil collecting pipes in transformer radiators. Through PLC program control, servo motor-driven lead screw feeding, and adjustable punching distance design, it achieves precise processing and efficient production of pipe punching positions, solving the problems of low efficiency and large positioning errors in traditional manual punching. It is suitable for large-scale standardized production scenarios.
Core Functions and Working Principles
Fully Automated Process Control
PLC Program Setting
Parameters such as punching spacing, number of punches, and pipe length are input through a human-machine interface (touch screen), and the PLC system automatically generates the punching path.
Servo-Driven Feeding
The servo motor drives a precision ball screw to move the oil collecting pipe linearly along the guide rail with high positioning accuracy. The feeding speed is adjustable from 0-4000mm/min, ensuring the punching spacing error ≤±1mm.
Punching Execution
Hydraulic or pneumatic punching molds (optional multi-station rotating dies) automatically punch at preset positions. The single punching time is <1 second. Punching types include round holes and kidney-shaped holes, adapting to hole diameters in the range of φ8-φ30mm.
Flexible and Adjustable Punching Modes
Free Punching Spacing Setting
Supports equally spaced punching (e.g., one punch every 45mm) and unequally spaced punching (e.g., mixed spacing of 50mm, 45mm, 40mm), meeting the punching layout requirements for different heat dissipation needs of radiators.
Strong Pipe Compatibility
By replacing V-shaped support blocks or adjustable fixtures, it adapts to oil collecting pipes with diameters of φ50-φ200mm and lengths of 500-6000mm, compatible with materials such as carbon steel and stainless steel.
