Problems solved by technology
[0004] However, due to the large diameter of the grinding wheel, the desktop sawing machine is not suitable for cutting small workpieces, and it is difficult to achieve accurate cutting when cutting small workpieces, and the current sawing machines can only move forward and backward. If the diameter of the workpiece is large, then this The processing time of this cutting method is relatively long, and the cutting surface is uneven and accurate
Both of the above two sawing machines have no control circuit, so the control performance and safety performance are not very good, and it is impossible to accurately cut precise parts in actual cutting.

The invention discloses a PLC secondary control loop of a hydraulic band sawing machine. The PLC secondary control loop comprises a PLC circuit and a touch screen circuit. The PLC circuit and the touch screen circuit are sequentially connected through a data line, a PLC is connected in the PLC circuit, and the touch screen circuit is connected to a main power through a switching power supply. By the adoption of the mode, the control performance and the safety performance of the sawing machine can be effectively improved, and precise parts can be cut.
Description
technical field [0001] The invention relates to the field of sawing machine control loops, in particular to a PLC secondary control loop of a hydraulic band sawing machine. Background technique [0002] Sawing machines are commonly used cutting devices when people cut off or cut off various workpieces. Existing sawing machines are roughly divided into hand-held sawing machines and table sawing machines. The hand-held sawing machine is small in size and usually has a housing in which a motor and other components are arranged. On one side of the housing, there is a grinding wheel as a cutting tool. The grinding wheel is driven by the motor to adjust and rotate for cutting workpieces. The hand-held sawing machine also has a handshake part, and when in use, the handgrip part is held by hand to carry out cutting operations. [0003] The diameter of the grinding wheel used in the hand-held sawing machine is small, usually 100 mm to 200 mm in diameter. Since the hand-held sawing m...
