Advanced ring die drilling technology is mainly reflected in the following aspects:
• Intelligent fixed hole dredging device: In order to solve the problems of low efficiency, low automation and easy damage in traditional ring die drilling, researchers developed an intelligent fixed hole dredging device. The device combines the high permeability ferromagnetic and magnetic leakage detection principles, as well as the Hall effect detection algorithm, to realize automatic detection and clearing of blocked die holes, and improves the accuracy of hole positioning. Experimental results show that the device’s dredging efficiency can reach 1260 holes/hour, the die hole scratch rate is less than 0.15%, the operation is stable, and the device can automatically dredge the blocked ring die.
• CNC feed ring die drilling equipment: The CNC feed ring die drilling equipment developed by Mylet completely replaces the manual drilling process and significantly improves the smoothness of the holes and drilling efficiency.
• New ring die and its processing method: This technology involves a new type of ring die and its processing method. Its characteristic is that the central axis of the die hole intersects with the extension line connecting the center of the ring die and the center of the pressure wheel at the inner wall of the ring die, forming a An angle greater than 0 degrees and less than or equal to 90 degrees. This design reduces the angle between the extruded direction of the material and the direction of the die hole, making more effective use of power, reducing energy consumption, and improving production efficiency; at the same time, the intersection area formed by the die hole and the inner wall of the ring die increases, and the die hole The inlet is enlarged, the material enters the die hole more smoothly, the life of the ring die is extended, and the equipment usage cost is reduced.
• Deep hole drilling machine: MOLLART has developed a deep hole drilling machine specifically for flat ring dies, which are used in the animal feed and biological industries. The 4-axis and 8-axis ring die deep hole drilling machines on offer can drill holes from Ø1.5mm to Ø12mm in diameter and up to 150mm deep, with ring die diameters from Ø500mm to Ø1,550mm, and hole-to-hole drilling times. Less than 3 seconds. The 16-axis deep hole ring die machine tool is developed for mass production of ring dies, and can achieve unmanned operation during drilling.
• Granulator Intelligent Manufacturing Center: Zhengchang Granulator Intelligent Manufacturing Center adopts the most advanced ring die drilling production technology and has more than 60 gun drills to provide customers with high-quality ring die drilling services.
The development and application of these technologies not only improve the efficiency and quality of ring die drilling, but also reduce production costs, playing an important role in promoting the development of the pellet manufacturing industry.
