Description

Technical Field

[0001] The invention belongs to the technical field of numerical control center equipment, and specifically relates to a numerical control machine tool working fluid recycling device and a use method. Background Art

[0002] Wire electric discharge cutting (WEDM) is a type of CNC machine tool. Its basic principle is to use a continuously moving thin metal wire as a tool electrode, and pass a pulse current between the metal wire and the workpiece, and use the pulse spark discharge effect between them, and through the relative movement of the electrode wire and the workpiece, the workpiece is cut and formed. Wire electric discharge cutting is also referred to as wire cutting. Early wire cutting technology was mainly used in the processing of metal parts. With the development of technology, wire cutting is also used in the cutting of non-metallic parts. For example, wire electric discharge cutting is suitable for various high-hardness and high-temperature resistant ceramic materials, such as aluminum oxide, silicon carbide, etc. These materials are difficult to cut by traditional mechanical processing methods, but can be precisely cut by high-temperature discharge of electric sparks; at the same time, some plastic materials can also be processed by wire electric discharge cutting under specific process conditions. Common examples include engineering plastics and certain composite materials. Since wire cutting is different from general mechanical cutting and belongs to discharge machining, wire cutting machining fluid not only has the functions of cooling, chip removal, lubrication, and rust prevention, but also directly participates in the machining process as a discharge medium.

[0003] A large amount of debris will be generated during the online cutting process. Currently, most manufacturers pump the mixture of these debris and working fluid into the recycling system through a circulation pump. Since the treatment and filtration of solid debris are relatively simple, the solid debris causes greater wear on the circulation pump and even causes abnormal shutdown during work, affecting product quality and even production progress. In addition, in the treatment of working fluid, the flow rate is generally constant.

[0004] The authorization announcement number CN116275336B discloses a wire cutting machine tool protective cover that is easy to install. By splitting the protective cover into six components, the six components are independently packaged, and the components can be assembled before being assembled to the wire cutting machine tool, which greatly reduces the difficulty of assembly, saves assembly time and cost, and the oil tank shield component can prevent the splashing of cutting fluid, and the head cover shield component can recycle the cutting fluid mist to achieve the recycling of cutting fluid. The assembler can realize the installation of the shield top plate and the shield enclosure through the cooperation of the connecting block and the connecting groove without the assistance of others, which is more convenient and reduces manpower consumption. The positioning rod can be accurately positioned by moving the adjustment plate in any direction on the inner side of the movable hole to prevent the deformation of the shield enclosure from being unable to be positioned and installed. Although the invention can realize the recovery of cutting fluid mist, it does not process the solid debris in the cutting fluid, and the accumulation degree of solid debris cannot be timely understood through the protective cover component, resulting in the problem of not being able to clean up in time and affecting the processing quality of the workpiece.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The present invention provides a working fluid recycling device for a numerically controlled machine tool. Through the arrangement of a first temporary storage barrel assembly, a temporary storage barrel liquid outlet pipe assembly, a solid-liquid separation assembly, a separation box support frame, a cylinder assembly, a slag removal assembly, a second temporary storage barrel assembly and a PLC control system, the solid debris in the working fluid can be separated in time, and the working fluid can be recycled and reused, thereby effectively improving the resource utilization efficiency of the entire processing process. The center of gravity of the separation box body is arranged on the axis of the separation box deflection shaft. Under the action of the elastic support assembly, when the liquid height in the C area of ​​the separation box body is lower than the set value, the separation box body is always in a horizontal state; when the liquid height in the C area of ​​the separation box body is higher than the set value, deflection will occur, thereby facilitating the timely discharge of the working fluid.

[0037] The present invention provides a working fluid recycling device for a numerically controlled machine tool. When a separation box body is kept in a horizontal state, the inflow of working fluid containing solid debris causes an increase in the overall weight of the separation box body, thereby causing the piston to move downward; when the working fluid in the separation box body is discharged, the separation box body will quickly reset under the joint action of the elastic support assembly and the fifth spring, thereby causing the piston to move upward. During the movement of the piston, pressurized gas will be generated in the exhaust pipe and introduced into the drum assembly, thereby preventing the solid debris in the drum assembly from forming agglomerates and reducing the difficulty of subsequent cleaning.

[0038] The present invention provides a CNC machine tool working fluid recycling device, in which a separation box support frame and a separation box move as a whole in the height direction, thereby reducing the adverse effects of vibration. At the same time, through the setting of a reset component and a sealing door, the separation box body is in a "stuck" state, so large particles of solids can be removed quickly and conveniently.

[0039] The invention provides a CNC machine tool working fluid recycling device, wherein the slag removal component has a compact structure and is easy to operate, and the flow rate of the working fluid to the second temporary storage barrel can be regulated by adjusting the rotation angle of the rotating drum.
