A kind of nck high-speed servo feeder and its control method

Abstract

The invention discloses a NCK high-speed servo feeder and a control method thereof. The feeder comprises a base, main engine boards are symmetrically arranged on the base, a lower roller and an upperroller are arranged between the main engine boards through a bearing, the lower roller and the upper roller are arranged in parallel and are matched to clamp a material, a servo motor for driving thelower roller and the upper roller to work is arranged on the base, the control method comprises the steps of switching the work mode of the servo motor between the displacement mode and the moment mode, clamping and loosening of the material are controlled, and the stamping precision is ensured; and a loosening assembly does not need to be arranged, control through one servo motor is achieved, theequipment cost and the control cost of the feeder are greatly reduced, and meanwhile, due to the fact that the loosening assembly easily damaged is abandoned, the service life of the feeder is prolonged.

Description

technical field [0001] The invention relates to the technical field of punch feeding, in particular to a control method for an NCK high-speed servo feeder. Background technique [0002] In the mechanical stamping industry, when the punch press is stamping, it is necessary to transport the pre-rolled steel material to the punch press. The general process is to uncoil the steel material first, and then transport it to the punch press through the feeder for stamping. [0003] In the process of the feeder clamping and feeding the punch to the punching machine, there must be a mechanical release for each punching. The reason is that the feeding machine uses the upper and lower rollers to clamp the material and transport it to the punching die. If the punching press is punching, the upper and lower rollers are still clamped. The device will cause micro-deformation of the steel, which will affect the stamping accuracy. Therefore, at the moment of punching, it is necessary to lift ...

AI Technical Summary

Problems solved by technology

[0004] At present, the relaxation and reset of the upper roller are generally realized by the cylinder, eccentric structure, etc., and the lifting and reset of the upper roller are controlled by the reciprocating action of the system control cylinder and the eccentric structure. The structure and control are more complicated, especially with the ultra-high-speed feeding. With the popularization of machine tools, this traditional relaxation component cannot meet the stamping frequency requirements, and the high-frequency reciprocating motion of the relaxation component also affects the service life of the equipment and increases the production cost of the equipment.
