Features
- The valve hole punching machine separates the traditional valve hole flattening, punching, and deburring processes into three dedicated units, solving common issues with standard machines, such as frequent punch breakage and difficult punch replacement.
- The automated loading and unloading system is driven by a high-power servo motor, ensuring consistent accuracy in positioning for each rim.
- Equipped with an independent hydraulic drive and electrical control system, the punch press utilizes PLC control, allowing for three operation modes: adjustment, manual, and semi-automatic.
- Includes over-travel and over-pressure protection, emergency stop, and filter clogging alerts for enhanced safety and reliability.
- Operating parameters such as working pressure, speed, and stroke range are fully adjustable to meet specific production requirements.
- Using image recognition technology, the system precisely identifies and locates the weld seam as the wheel rotates on the detection platform.
- The main frame can be adjusted for height, width, and tilt to accommodate rims of various sizes and specifications.
