The development of stamping processing towards high precision, high efficiency and high automation is an inevitable trend of the industry. This puts higher demands on the matching feeder equipment of the press, and also promotes the continuous updating and replacement of the punch feeder, from the initial The first generation of air feeders, to the second generation of roller feeders, has a significant improvement in accuracy, stability, and automation, but still can not meet the increasingly high precision stamping needs, and the holding and feeding actions and The connection of the stamping points of the mold is not good, and the debugging of the feeder machine is relatively cumbersome, and it has become increasingly unable to meet the needs of modern stamping processing.
NC feeder assembly
For this punching machine, the third-generation NC feeder was born. It is driven by a Mitsubishi servo motor as a feed roller. Mitsubishi PLC is equipped with a 7-inch high-precision touch screen as a control method. The signal line is connected to the cam of the punching machine to make full use of the punching machine. The time on the action path of the crankshaft realizes the feeding, feeding, returning, and clamping operations, and the feeding operation is flexibly completed, and the complete punching synchronization operation is realized. At the same time, the feeding length, the feeding times and the feeding speed are all in Jinzhide. The simple setting of the touch screen panel of the NC feeder is simple and convenient.
NC feeder test machine
It changed the problem that the feeding machine often fails to be timely and inaccurate in the feeding action. Through the connection with the crankshaft cam, the whole feeding process can be optimized, and the application of the feeder equipment is increased. Range, improved feeding accuracy, automation and stability.
NC feeder use
The feeder is used in conjunction with the punching machine. When the punching crankshaft is clockwise to 90° in the 240° range, the servo feeding mechanism is allowed to feed. At 240°, the feeding action starts and follows the current angle of the punch to drive the feeder in a timely and even manner. When the crankshaft is running to 90°, the feeding is completed. Feeding in this way, the feed time makes full use of the entire feed interval. At the same time, the Jinzhide NC feeding mechanism is equipped with a relaxation function. The relaxation mechanism usually adopts a solenoid valve to control the driving mode of the cylinder. The action angle is generally after the safety angle is completed after the completion of the feeding, and the mold is completely in contact with the material. , to eliminate the cumulative error fundamentally, to ensure the stability of long-term feeding accuracy.
