Numerically-controlled double working position cutting machine and control method thereof

Abstract

The invention discloses a numerically-controlled double working position cutting machine. The numerically-controlled double working position cutting machine includes two cutting mechanisms and two clamp mechanisms; each cutting mechanism includes a feeding oil cylinder, a motor and a saw blade, the saw blades are mounted on the motors, and the motors are mounted on the feeding oil cylinders; eachclamp mechanism includes a clamp oil cylinder and a workpiece copying mold, the workpiece copying molds are mounted on the clamp oil cylinders, and the cutting mechanisms and the clamp mechanisms arecooperatively mounted. The invention further discloses a control method of the numerically-controlled double working position cutting machine. The control method includes the steps that a PLC receivesposition signals of a position feedback sensor and conducts judging; when a feeding position is close to the 1 / 3 position of the upper portion of a workpiece, the PLC controls the opening degree of aservo proportioning valve to increase, and the workpiece is fed and subjected to acceleration cutting; when the feeding position is close to the 1 / 3 position of the lower portion of the workpiece, the PLC controls the opening degree of a servo proportioning valve to reduce, and the workpiece is fed and subjected to reduction cutting. By adopting the numerically-controlled double working positioncutting machine and the control method thereof, the number of turnover times of the machined workpiece is reduced, and the machining efficiency is high; the numerically-controlled double working position cutting machine is small in occupied space, low in manufacturing cost, high in machining control accuracy and safety performance and convenient to maintain.

Description

technical field [0001] The invention belongs to the field of cutting machines, and in particular relates to a cutting machine for synchronously cutting both ends of a workpiece and an electric automatic control method. Background technique [0002] The workpiece is generally bent by a CNC bending machine to meet the requirements of the bending angle. In order to meet the end face size and end face quality of the bent workpiece, further cutting processing is required. Most of the existing cutting machines use the process of cutting both ends of the workpiece in sequence. , Every time the cutting process of one end is completed, the workpiece often needs to be re-clamped, which increases the turnover times of the workpiece and reduces the processing efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a numerically controlled double-station cutting machine, which can reduce the turnover, reduce the floor space of the equipment, th...
