Automatic cutting machine

Abstract

An automatic cutting machine comprises a chassis, a frame, a main motor, a protective cover and a blade. The blade is driven by the main motor and is integrated with the main motor and the protective cover. The chassis is provided with a feed screw vertical to the chassis, a feed sliding plate which can move up and down along with rotation of the feed screw is arranged on the feed screw, the main motor is fixed on the feed sliding plate, the feed screw is driven by a feed motor arranged on the frame, the feed motor adjusts the rotation speed and the rotation direction by an automatic control unit, and further controls the feed speed, the down cut and the reset of the cutting machine based on the rotation speed and the rotation direction. By virtue of an automatic feed cutting mode, the cutting machine can help reduce the labor intensity of workers, prolong the service life of the motors, improve the machining precision and safety performance of the cutting machine, and improve the processing precision and safety performance.

Description

Technical field: [0001] The invention relates to a cutting device, in particular to a profile cutting machine capable of automatically cutting workpieces. Background technique: [0002] Existing profile cutting machines all adopt the manual feed operation mode, that is, the handle that is installed as one with the blade is pressed down by manpower, so that the blade cuts the workpiece. The disadvantages of this method of operation are: 1. High labor intensity; 2. When using, the downforce is not easy to control, and the heavy or light has a great impact on the motor, which seriously shortens the service life of the motor; 3. The cutting machine is in the When working, the blades (both are grinding wheels) are only used for grinding, so they should not be under too much pressure. In the actual operation process, affected by factors such as the production environment, the operator is often impatient during operation, and always Just think about it and cut off the workpiece, u...

Problems solved by technology

The disadvantages of this method of operation are: 1. High labor intensity; 2. When using, the downforce is not easy to control, and the heavy or light has a great impact on the motor, which seriously shortens the service life of the motor; 3. The cutting machine is in the When working, the blades (both are grinding wheels) are only used for grinding, so they should not be under too much pressure. In the actual operation process, affected by factors such as the production environment, the operator is often impatient during operation, and always Just think about it and cut off the workpiece, usually with too much force, which will easily cause overload damage to the equipment motor and overpressure of the cutting blade, resulting in a chipping accident, which is life-threatening; 4. Manual pressure can easily cause the blade to swing left and right during processing. Affect machining accuracy

In addition, the currently commonly used cutting machines do not have a dust collection design, and the sparks and dust splashes generated by grinding are relatively large during work, which poses a great hidden danger to the environment and fire prevention.
