Description

Cutting device

The present invention relates to a cutting device, and more particularly to a cutting device that utilizes a plurality of sensors and a clutch to cooperate to drive a cutter.

Wire cutting devices are widely used in many fields to cut a full length of metal wire, metal bars, etc. into a desired length.

However, the conventional cutting machine generally uses the method of air pressure and oil pressure to drive the cutter, so that the overall size of the processing machine is large, the components are complicated, and the reaction speed is slow and the working stroke is irrespective of the air pressure or oil pressure cutting machine. Long is one of the shortcomings of urgent need for improvement.

Further, in addition to the above-described cutting machine, there is also a processing machine for cutting a wire with a saw blade, but such a processing machine is prone to generate more iron filings during cutting, and at the same time, due to friction when sawing back and forth, The heat energy is easy to affect the properties of the wire.

In view of this, how to eliminate the above-mentioned defects is the technical difficulty point that the inventor of the case wants to solve; however, the inventor of this case is based on years of experience in the relevant industry, after many years of painstaking research, trial improvement, finally Successfully developed the case and made the invention born to enhance the efficacy.

In view of the above disadvantages, the cutting device of the present invention comprises: a machine having a front end provided with at least one first sensor. a transmission unit having a frame body, a transmission block, a clutch, an eccentric transmission shaft coupled to the clutch, and a second power source coupled to the clutch, the housing body having an accommodation space and two sides respectively The first through hole is penetrated, and the transmission block is provided with a second through hole penetrating therein, and is disposed in the accommodating space of the frame body, so that each of the first through holes is opposite to the second through hole, and the eccentric transmission shaft is threaded through The frame body, the first through holes and the second through holes allow the frame to be suspended in the frame body, and the clutch is electrically connected to the first inductor and the second inductor. And cutter The unit is disposed below the frame body. When the workpiece passes through the frame body to the front end of the machine frame and is sensed by the first sensor, the clutch drives the eccentric transmission shaft to rotate, so that the frame body is pressed down and the cutter unit is pressed. When the workpiece is broken and the frame is reset by the second sensor after the cutting, the clutch stops driving the eccentric drive shaft.

The main purpose of the cutting device of the invention is: high safety and easy operation, and the distance between the first sensor and the tool unit can quickly adjust the required length without setting complicated computer parameters or artificial Adjust to increase cutting efficiency.
