Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a wire cutting machine. Background Art

[0002] The wire cutting machine is mainly composed of three parts: machine tool, CNC system and high-frequency power supply. The CNC system is composed of single-chip microcomputer, keyboard, frequency conversion detection system, and has the main functions of gap compensation, linear interpolation, circular interpolation, automatic wire breakage processing, etc. It can cut materials such as high-strength, high-toughness, high-hardness, high-brittleness, magnetic materials, as well as precision and small parts with complex shapes.

[0006] When using a wire cutting machine in the technical solution, the workpiece is placed on the upper side of the guide roller, and the workpiece is fed and conveyed by rotating the guide roller. When the workpiece enters, the motor in the drive box is started to drive the wire wheel to rotate, and the wire wheel drives the cutting wire to transmit at high speed to generate cutting force. The electric telescopic rod is started to drive the top plate to descend. At this time, the cutting wire descends to cut the workpiece. High-temperature heat is generated during the cutting process. The built-in pump body of the top box is started to send the coolant into the internal cavity of the circulation frame through the conduit, and then it is discharged outward through the nozzle. The sprayed coolant is sprayed onto the cutting line to achieve cooling.

[0011] Preferably, both ends of the top box are penetrated with a hose, and the lower end of the hose passes through the holes at both ends of the top plate and then connects to the inside of the box body. The hose cooperates with the internal reflux pump of the box body to reflux the cooling liquid in the box body into the top box.

[0012] Preferably, a liquid injection pipe is installed through one end of the upper end surface of the top box, and a sealing cap is threadedly installed on the outer end of the liquid injection pipe. The sealing cap is opened and coolant is added into the top box through the liquid injection pipe.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the operator starts the device through an external control device and places the workpiece on the upper side of the guide roller. The workpiece is fed into and conveyed by the rotation of the guide roller. When the workpiece enters, the motor in the drive box is started to drive the wire wheel to rotate, and the wire wheel drives the cutting wire to transmit at high speed to generate cutting force. The electric telescopic rod is started to drive the top plate to descend. At this time, the cutting wire descends to cut the workpiece. High-temperature heat is generated during the cutting process. The pump body built into the top box is started to send the coolant into the internal cavity of the circulation frame through the conduit, and then discharged outward through the nozzle. The sprayed coolant is sprayed onto the cutting wire to achieve cooling. The excess coolant flows back into the groove of the box body, enters the box body after being filtered through the filter net, and is returned to the top box through the reflux pump in the box body in conjunction with the hose to achieve circulation. The device has a simple structure and is easy to operate. It reduces energy consumption through the recycling of the coolant. The built-in filtering mechanism avoids pipeline blockage. At the same time, the compact structural design makes the device occupy a small area, which is convenient for processing small parts. BRIEF DESCRIPTION OF THE DRAWINGS
