In the feeding process, the three-in-one feeder requests the positioning accuracy in the feeding process, and usually requests the positioning pin to be set in the mold to eliminate the feeding error each time, so the feeding device needs to have the relaxation function, and the feeding step is completed at each feeding step. In the future, it is necessary to relax the feed roller to arrive at each article to position it from the beginning to eliminate the cumulative error of each feed.
Nowadays, with the continuous development of the times, many requests for quality and quantity are becoming more and more severe. Just like today's requests for many mechanical aspects are also different. Let's think that the three-in-one feeder should have a high degree of automation, leveling, good feeding accuracy, high punching synchronization function, simple operation, great saving manpower and space, and won the ever-added stamping customers. Love. However, with the addition of the required amount, the domestic manufacturers engaged in the production of three-in-one feeders are constantly added, but the quality that comes with them has also been mixed, especially in the planning and production, which highlights the constant addition of questions. Today, the price of the South China Sea straightening machine is exemplified by several common handling techniques for the three-in-one feeder. Let's learn together:
In the feeding process, the three-in-one feeder requests the positioning accuracy in the feeding process, and usually requests the positioning pin to be set in the mold to eliminate the feeding error each time, so the feeding device needs to have the relaxation function, and the feeding step is completed at each feeding step. In the future, it is necessary to relax the feed roller to arrive at each article to position it from the beginning to eliminate the cumulative error of each feed. In addition, the three-in-one feeder is used during the process of relaxation. The power source used for relaxation is the air pressure, and it is usually used in conjunction with the punching machine. It is inevitable that there will be an oscillation, and it will often be caused by the oscillation of the three-in-one. The positioning screw is loose and affects the leveling feeding accuracy. Therefore, the method adopted today is to directly process the countersunk hole on the side plate, and the spacing between the tapping and fixing plates on the positioning shaft end may not be added. Condition the positioning axis to eliminate errors.
Faulty disease, analysis of the disease: coiled snake
Analysis of the elements: 1. The width of the material roll and the orientation of the material wheel are not suitable; 2. The pressure of the roller is uneven; 3. The slippage is stuck; 4. The pressure of the roller is too large.
Sweeping method: 1. Adjusting from the beginning; 2. Adjusting from the beginning; 3. Checking whether the mold guide groove is in line with the NC, whether there is scrap rising in the mold, whether the data has burrs; 4. Adjusting from the beginning.
Fault 2: sudden errors in feeding
Analysis of the elements: 1. Whether the adjustment of the data by the NC feeder is suitable; 2. The transmission gap between the roller and the servo motor is too large; 3. The unevenness of the coil material.
Sweeping method: 1. Is the speed of the leveling machine NC adjusted, or whether the leveling and NC base spacing and material arc height and punching speed are appropriate; 2. Adjust the belt; 3. Check the length and width of the coil. Thickness is not a norm.
Fault 3: Feeding errors have a fixed direction
Analysis of the elements: 1. The feed wheel pressure is lacking; 2. The feed length is too long; 3. The feed is lacking; 4. There is hair or material attack in the mold.
Sweeping method: 1. Add pressure; 2. The upper mold is unloaded to form a pulling material; 3. Check whether the width of the coil and the orientation of the mold guide plate are appropriate, or whether the mold and the NC are in a straight line; Does the board and stripper have burrs and foreign objects?
