Description

Technical Field

[0001] The utility model provides a vertical wire cutting machine tool, belonging to the technical field of mechanical processing devices. Background Art

[0002] The principle of wire EDM is to use a thin single-strand metal wire and deionized water to work through discharge between the metal wire and the workpiece. When the heat generated by the discharge reaches the melting point of the metal material, it is used to achieve a process of dissolving and gasifying the cutting and separation of the metal material. The continuously moving metal wire is used as an electrode to perform pulse spark discharge on the workpiece to erode the metal and cut and shape it. Since the electrode wire never contacts the metal being processed, wire EDM is a stress-free processing technology. It can easily process complex parts and precision parts with hard conductive materials. Any conductive material can be processed by EDM. The difficulty of the workpiece being processed has nothing to do with the metal hardness of the material being processed, because there is no significant physical cutting force during the cutting process. This technology can be used to process alloys with higher hardness and complex shapes. The metal wire selected for the processing electrode is usually well conductive and has a higher melting point, such as copper, graphite, copper-tungsten alloy, and molybdenum. During the reprocessing process, the working electrode and the product are simultaneously lost. The coolant is used as a discharge medium to cool and remove chips during processing. Deionized water and emulsion are usually selected.

[0003] At present, when the wire cutting machine is in use, a large amount of coolant will be sprayed on the processing electrode. Most of the coolant will flow back and be reused after filtering. However, the speed of the electrode wire is relatively fast during operation. Under the action of tension, a small amount of coolant will be adsorbed on the metal wire. Then when the electrode wire is wound on the thread rolling drum, the thread rolling drum will throw out the coolant when rotating, resulting in the loss of coolant and environmental pollution. In addition, the electrode wire of the existing device is exposed when cutting the workpiece, so it is more dangerous when cutting. Utility Model Content

[0006] As an improvement, the machine tool includes a workbench, a fixing mechanism slidably arranged on the workbench to mount a workpiece, a wire guiding mechanism to control the direction of the electrode wire, and a cooling mechanism to cool the electrode wire;

[0007] As an improvement, the water shield includes diamond plates respectively arranged on both sides of the thread rolling cylinder, a top plate arranged on the upper ends of the two diamond plates, a bottom plate arranged on the lower ends of the two diamond plates, and a rear plate arranged at the rear ends of the two diamond plates;

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] according to Figure 1—4 shows: the utility model provides a vertical wire cutting machine tool: comprising a machine tool 1, a thread rolling drum 2 slidably arranged at the rear side of the machine tool 1; a water retaining cover 3 is arranged at the rear of the thread rolling drum 2, the lower end of the water retaining cover 3 is connected to the cooling mechanism 5 of the machine tool 1 through a hose 4, and corresponding infrared transmitters 7 and infrared receivers 8 are respectively arranged on both sides and the front end of the workbench 6 of the machine tool 1; wherein the machine tool 1 comprises a workbench 6, a fixing mechanism 9 slidably arranged on the workbench 6 for mounting a workpiece, a wire guiding mechanism 10 for controlling the direction of the electrode wire, and a cooling mechanism 5 for cooling the electrode wire; by arranging the water retaining cover 3 and the hose 4, the coolant adhering to the electrode wire can be thrown into the water retaining cover 3 when the electrode wire is wound on the thread rolling drum, and then returned to the cooling mechanism 5 through the hose 4, thereby avoiding the loss of coolant and polluting the environment, and by arranging the infrared transmitter 7 and the infrared receiver 8, when an object is at the edge of the workbench 6, it can be identified, so that the machine tool stops operating, thereby increasing the safety of the machine tool;

[0020] The water shield 3 includes rhombus plates 301 respectively arranged on both sides of the thread rolling drum 2, a top plate 302 arranged at the upper ends of the two rhombus plates 301, a bottom plate 303 arranged at the lower ends of the two rhombus plates 301, and a rear plate 304 arranged at the rear ends of the two rhombus plates 301; wherein the upper end surface of the bottom plate 303 is not higher than the upper end surface of the bottom plate of the thread rolling drum 2; thus, the coolant thrown into the water shield 3 can all be returned to the cooling mechanism 5 through the hose 4, so as not to flow onto the bottom plate of the thread rolling drum 2;

[0021] Among them, the circuits of the infrared transmitter 7 and the infrared receiver 8 are connected in series with the circuit of the machine tool 1; wherein, the recognition range of the infrared transmitter 7 and the infrared receiver 8 is the vertical part of the electrode wire located in the wire guide mechanism 10; in this way, when the infrared receiver 8 cannot receive the infrared rays emitted by the infrared transmitter 7, the machine tool 1 will be powered off, thereby stopping the operation and increasing the safety of the machine tool 1.

[0022] The principle of the utility model is as follows: when in use, the raw material is first placed on the fixed parts 9 of the workbench 6, and then one end of the electrode wire is fixed on one side of the thread rolling drum 2, and then the thread rolling drum 2 is rotated so that the electrode wire is completely wound on the thread rolling drum 2, and then the unfixed end of the electrode wire is passed through the wire guiding mechanism 10 and the raw material and fixed on the other end of the thread rolling drum 2, and then the machine tool 1 and the thread rolling drum 2 are started. When the electrode wire processes the raw material, the cooling mechanism 5 will cool the vertical part of the electrode wire located in the wire guiding mechanism 10, and part of the coolant will flow on the workbench 6, and part of it will be adsorbed on the electrode wire. When the electrode wire is winding around the thread rolling drum 2, the coolant will be thrown onto the water retaining cover 3, and then to the lowest point of the flow channel water retaining cover 3, and then return to the cooling mechanism 5 through the hose 4. When the machine tool 1 is in operation, the infrared ray emitted by the infrared transmitter 7 is blocked, and the infrared receiver 8 cannot receive the infrared ray, which will cause the machine tool 1 to be powered off, thereby suspending the operation, thereby increasing the safety of the machine tool.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
