Difunctional cutting machine control system

Abstract

The invention provides a difunctional cutting machine control system. The difunctional cutting machine control system is characterized in that the system comprises a frequency converter and a PLC, andthe frequency converter is connected with a revolution motor; a first circuit breaker is connected with a first intermediate relay, and the first intermediate relay is connected with a clutch; the clutch is connected with the revolution motor; the intermediate relay is connected with a cooling fan; a three-phase supply is connected with three alternating current contactors; and the three alternating current contactors are connected with a cutting motor, a hydraulic motor and a dust collection motor. The difunctional cutting machine control system has the advantages that the frequency converter cooperates with the revolution motor, stepless speed change of cutting and revolution can be controlled, and adjusting is conducted according to specific pipes; and through a pulse encoder and a meter wheel coaxially installed with the pulse encoder, fixed length precise automatic cutting can be achieved, quick switching between chipping-free cutting and chipping cutting can be achieved, the special cutting requirements are met, cutting action manual / automatic switching operation is conducted, and debugging is facilitated.

Description

technical field [0001] The invention relates to the field of pipe material cutting, in particular to a control system of a double-action cutting machine. Background technique [0002] The existing plastic pipe cutting machine control systems on the market are as follows: [0003] (1) Control system of cylinder type pipe chipless cutting machine: [0004] This kind of control system controls the lifting and lowering of the blade by controlling the expansion and contraction of the cylinder, so as to achieve the purpose of cutting pipes; the cylinder is connected to the blade, the blade is fixed on the blade through the blade seat, and the blade is prevented from loosening through the fixed block, and the electromagnetic reversing valve controls the blade During the cutting process, there are cylinder clamping devices to compress the pipe material. After the cutting is completed, the clamping device is released and the blade returns to the initial position. Disadvantages of t...

AI Technical Summary

Problems solved by technology

Disadvantages of this control system: 1. The cutting process is difficult to control, the generated pressure is unstable, and the incision is not smooth enough; 2. The blade feed speed is difficult to control, and it is difficult to achieve high-speed cutting

Disadvantages of this control system: 1. This type of plastic profile cutting device has too much sawdust and is difficult to collect, which is likely to cause environmental pollution, waste of raw materials, and affect the health of the operator; 2. This type of plastic pipe cutting device works When the noise is too loud, it will also cause harm to the operator's body
