Intelligent computerized numerical control (CNC) spring machine

Abstract

The invention discloses an intelligent CNC spring machine used for processing extension springs, compression springs, torsion springs, spiral springs and the like. The intelligent CNC spring machine comprises a straightening mechanism, a wire feeding mechanism, a pitch mechanism, a core seat mechanism, a knife seat mechanism and a computer control system. The pitch mechanism comprises a pitch servo motor and a pitch ball screw pair driving a pitch shaft to move; the core seat mechanism comprises a core seat lifting mechanism and a core rod core-pulling mechanism; and the knife seat mechanism comprises a plurality of sliding knife seats and knife seat driving mechanisms and can move along an arc-shaped track in a radial direction. The spring machine is provided with five sections including a straightening section, a wire feeding section, a pitch section, a core seat section and a knife seat section according to the principle of spring formation, and has reasonable structure design and is driven by a full servo and controlled by a computer so as to realize fully closed loop control and be capable of reducing the rejection rate of finished products. The intelligent CNC spring machine can be widely applied to the production of various extension springs, compression springs, torsion springs, spiral springs and the like, with simple operation, high processing precision and high production efficiency.

Description

technical field

[0001] The invention relates to a spring processing equipment, in particular to an intelligent computer numerical control spring machine, which is suitable for processing tension springs, compression springs, torsion springs, scroll springs and the like. Background technique

[0002] At present, spring processing equipment is divided into mechanical transmission type and computer numerical control type according to the working mode. Mechanical adjustment is difficult, labor-intensive, inefficient, and limited by the shape of the spring. Computer numerical control type is divided into computer universal spring machine and computer compression spring machine according to the type of spring processed. The computer universal function can process springs with complex shapes. Spring shape restrictions. The computer compression spring machine is mainly used to process various compression springs. The efficiency of processing compression springs is higher than that...
