Technical Field

[0001] The invention relates to the technical field of cutting, in particular to an adjustable wire cutting machine tool. Background Art

[0002] Wire cutting machine is an electrical processing technology originated from the Soviet Union in 1960. It was created and invented by Lazarenko and his wife when they were studying the phenomenon of switch contacts being damaged by spark discharge corrosion. Its basic principle is to use free positive ions and electrons to quickly form an ionized conductive channel in the field. When a current is formed between the two plates, countless collisions occur between the particles to form a plasma zone, and the temperature rises rapidly to 8000 to 12000 degrees, causing the materials on the surfaces of the two conductors to melt instantly. At the same time, due to the vaporization of the electrode and the electrolyte, a bubble is formed, and the pressure rises to a very high level. Then the current is interrupted, the temperature drops sharply, and the bubble explodes inward. The power generated throws out the molten material, and the corroded material re-condenses into small spheres in the electrolyte and is discharged. Through the monitoring and control of NC control and the execution of the servo mechanism, this discharge phenomenon is made uniform and consistent, so as to achieve the purpose of cutting the workpiece.

[0003] Wire cutting machine tool technology is mainly divided into three types: fast wire, medium wire and slow wire. They all use metal wire as a tool to process conductive materials through the principle of electric spark discharge. Fast wire is suitable for rough processing and removal of large amounts of material, while slow wire is suitable for fine processing and removal of small amounts of material. The electrode wire material is usually molybdenum wire or copper wire, which has good conductivity and relatively low melting point. During the processing, a high-frequency pulse power supply is used to provide the energy required for processing, and the discharge process is controlled by pulse parameters. At the same time, a special working fluid is used to cool, lubricate and remove the debris generated by the discharge.

[0004] The tightness of the electrode wire in the wire cutting machine directly affects the cutting efficiency, quality and equipment maintenance, and needs to be adjusted reasonably to ensure the best cutting effect and stable operation of the equipment. Summary of the invention

The two first electric guide rails are symmetrically arranged and arranged inside the working cylinder. The two first electric guide rails are fixedly connected to the working cylinder and electrically connected to the controller.

The lower end of the conical funnel is communicated with the collecting box, and the upper end is communicated with the working cylinder.

[0021] After the trigger button is turned on, the controller turns on the water pump. When the controller turns on the water pump, the water pump transports the coolant in the collection box to the universal nozzle through the connecting pipe. The coolant is sprayed onto the workpiece and the electrode wire through the universal nozzle to clean the metal debris on the workpiece and the electrode wire, and cool the workpiece and the electrode wire at the same time to prevent the heat generated during cutting from causing temperature stress in the workpiece, resulting in internal damage to the workpiece, and to prevent overheating and damage to the electrode wire.

A plurality of holes for filtering are arranged on the conveyor belt, and the conveyor belt is sleeved on the first rotating roller and the second rotating roller, and the conveyor belt passes through the second opening and the third opening.

[0025] After the coolant cools the workpiece and electrode wire, the coolant drives the metal debris through the conical funnel and falls onto the conveyor belt. The conveyor belt filters the metal debris in the coolant, and the filtered coolant enters the collection box, thus completing the circulation of the coolant.

[0026] When the second motor is started, the second motor rotates to drive the first rotating roller to rotate, and the first rotating roller and the second rotating roller cooperate to drive the conveyor belt to rotate. The conveyor belt transports metal debris into the debris box for easy handling by the staff.

Then the controller turns on the first electric guide rail, the second electric guide rail and the water pump, so that the workpiece can be cut and cooled after the electrode wire starts working, thereby reducing the consumption of the electrode wire and improving the processing efficiency.
