Description

Technical Field

[0001] The present invention relates to the technical field related to mold processing, and particularly to a slow wire cutting device for high-precision molds. Background Art

[0002] Slow wire cutting is a type of electrical discharge wire cutting. It uses a continuously moving thin metal wire (called the electrode wire) as the electrode to perform pulsed spark discharge on the workpiece to erode metal and cut into shape. It is mainly used for processing various workpieces with complex shapes and precision and small sizes. According to the running speed of the electrode wire, electrical discharge wire cutting machines are usually divided into two categories: one is slow wire (also called low-speed wire electrical discharge wire cutting machine), where the electrode wire moves in a low-speed one-way motion, generally with a wire walking speed lower than 0.2 mm / s, an accuracy of 0.001 mm level, and the surface quality is also close to the grinding level. The electrode wire is no longer used after discharge, the work is stable, uniform, with small jitter, and the processing quality is good. Moreover, with advanced power supply technology, high-speed processing has been achieved, and the maximum productivity can reach 350 mm2 / min. Since the slow wire cutting machine adopts the method of continuous wire supply for the wire electrode, that is, the wire electrode completes processing during movement, even if the wire electrode is worn, it can be continuously replenished, so the machining accuracy of parts can be improved. The surface roughness of the workpieces processed by slow wire cutting machines can usually reach Ra = 0.12 μm and above, and the roundness error, straightness error, and dimensional error of slow wire cutting machines are much better than those of fast wire cutting machines. Therefore, slow wire cutting machines are widely used in the processing of high-precision parts.

[0003] Currently, during the processing of molds by the existing slow wire cutting devices, generally, fixtures are required to lock the molds to ensure the stability of the molds during the cutting process. However, the existing mold fixtures are generally of a fixed structure, that is, they can only lock the fixed positions of the molds, such as the left and right sides or the front and back. However, when the slow wire cutting device cuts the mold, it often needs to perform cutting operations from different positions on the four sides of the mold. At this time, the fixture will block the cutting position of the slow wire. The current handling method is that after the staff stops the machine, manually remove the fixture, change the position of the mold, and then use the fixture to lock different positions of the mold. This operation method seriously affects the processing efficiency of the mold, and at the same time, the mold is prone to position deviation after being moved, thereby affecting the processing quality of the mold, and there is a certain room for improvement. Summary of the Invention

[0004] The purpose of the present invention is to provide a slow wire cutting device for high-precision molds to solve the problem that the fixture in the existing slow wire cutting device is difficult to automatically clamp and adjust different positions of the mold as mentioned in the above background art.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a high-precision slow wire cutting device for a mold, including a workbench 1, a positioning frame 2 is fixedly connected to the back of the workbench 1, a cutting assembly 3 is installed on the front of the positioning frame 2, a processing groove is opened on the upper surface of the workbench 1, a water-permeable plate 4 is fixedly connected to the inner wall of the processing groove, a fixture assembly 5 is fixedly connected to the upper surface of the water-permeable plate 4, a water-discharging assembly 6 is fixedly connected to the upper surface of the positioning frame 2, and filtering assemblies 7 are fixedly connected to both the left and right sides of the workbench 1;

[0023] The fixture assembly 5 includes a vertical fixture structure 51 and a horizontal fixture structure 52, and the vertical fixture structure 51 is used to block and position the mold during processing for the horizontal fixture structure 52.

[0024] Further, the vertical fixture structure 51 includes a rectangular frame 5101. Vertical plates 5102 are fixedly connected to both the front and back of the rectangular frame 5101. First support plates 5103 are fixedly connected to the upper surfaces of the two vertical plates 5102. First positioning plates 5104 are lapped on the upper surfaces of the two first support plates 5103. First mounting plates 5105 are fixedly connected to the fronts of the first support plates 5103 and the first positioning plates 5104. First bolts 5106 are threadedly connected to the upper surfaces of the two first mounting plates 5105. First cylinders 5107 are fixedly connected to the opposite backs of the two first positioning plates 5105. Vertical clamping plates 5108 are fixedly connected to the output ends of the two first cylinders 5107.

[0025] Further, the horizontal fixture structure 52 includes two cross plates 5201 which are respectively fixedly connected to the left and right sides of the rectangular frame 5101. Second support plates 5202 are fixedly connected to the upper surfaces of the two cross plates 5201. Second positioning plates 5203 are lapped on the upper surfaces of the two second support plates 5202. Second mounting plates 5204 are fixedly connected to the fronts of the second support plates 5202 and the second positioning plates 5203. Second bolts 5205 are threadedly connected to the upper surfaces of the two second mounting plates 5204. Second cylinders 5206 are fixedly connected to the opposite backs of the two second positioning plates 5203. Horizontal clamping plates 5207 are fixedly connected to the output ends of the two second cylinders 5206. When clamping the mold, turn on the two first cylinders 5107 to drive the two vertical clamping plates 5108 to clamp the front and back of the mold, which can ensure the stability of the mold during the cutting process, thereby improving the processing quality of the mold. When the two vertical clamping plates 5108 block the slow wire, there is no need for the staff to manually stop the machine. After disassembling the fixture, change the position of the mold and then clamp it, and then start the machine. Turn on the two second cylinders 5206 to make the two horizontal clamping plates 5207 press against the left and right sides of the mold. At the same time, the two first cylinders 5107 drive the vertical clamping plates 5108 to retract and move away from the mold, so that the position adjustment of the fixture for the mold can be quickly automated, thereby improving the processing efficiency of the mold. On the contrary, similarly, when the two horizontal clamping plates 5207 block the slow wire, the two first cylinders 5107 drive the vertical clamping plates 5108 to press against the front and back of the mold, and the second cylinders 5206 drive the horizontal clamping plates 5207 to retract and move away from the mold, with high flexibility. And by using the first mounting plates 5105, first bolts 5106, second mounting plates 5204 and second bolts 5205, the first positioning plates 5104 and the second positioning plates 5203 can be quickly removed from the first support plates 5103 and the second support plates 5202, which is convenient for quickly overhauling the first cylinders 5107 and the second cylinders 5206, and at the same time, the vertical clamping plates 5108 and the horizontal clamping plates 5207 can also be replaced.

[0026] Further, the water discharging assembly 6 includes a water tank 601. A water inlet pipe 602 is fixedly connected to the upper surface of the water tank 601. A sealing cover is threadedly connected to the top end of the water inlet pipe 602. A rectangular groove is formed in the front surface of the positioning frame 2. A water pump 603 is fixedly connected to the inner wall of the rectangular groove. An inlet end of the water pump 603 is communicated with a connecting pipe 604. An outlet end of the water pump 603 is communicated with a water delivery pipe 605. One end of the water delivery pipe 605 away from the water pump 603 is fixedly connected to a water outlet 606. The water pump 603 can convey the water in the water tank 601 to the processing tank through the connecting pipe 604 and the water delivery pipe 605, so as to immerse the mold and the fixture assembly 5, ensuring that the cutting assembly 3 can quickly cool the mold during the processing of the mold, thereby improving the processing quality.

[0027] Further, one end of the connecting pipe 604 away from the water pump 603 is communicated with the inside of the water tank 601, and the water outlet 606 is fixedly installed on the front surface of the positioning frame 2. A one-way valve 607 is installed on the surface of the water delivery pipe 605. Through the setting of the one-way valve 607, the water flowing into the processing tank through the water delivery pipe 605 and the water outlet 606 will not flow back.

[0028] Further, the filtering assembly 7 includes electric push rods 701. Output ends of both electric push rods 701 are fixedly connected with sealing plates 702. Sealing strips 703 are fixedly connected to opposite surfaces of the two sealing plates 702. And extrusion grooves adapted to the sealing strips 703 are formed in opposite surfaces of the two sealing plates 702. Receiving grooves are formed in the left and right inner walls of the processing tank, and the positions of the receiving grooves correspond to the positions of the sealing plates 702. The mutual cooperation and extrusion of the two sealing plates 702 and the sealing strips 703 can ensure that the water in the processing tank will not flow out during the processing, guaranteeing the sealing performance. After the processing is completed, the two electric push rods 701 drive the two sealing plates 702 to pull to both sides, so that the sealing strips 703 deformed by extrusion can be restored, and at the same time, the processing water in the processing tank can flow downward.

[0029] Further, a slot is formed in the front surface of the workbench 1. A strip-shaped frame 704 is inserted into the inner wall of the slot. A porous magnetic attraction plate 705 is fixedly connected to the inner wall of the strip-shaped frame 704. A filter screen 706 is fixedly connected to the inner wall of the strip-shaped frame 704, and the position of the strip-shaped frame 704 corresponds to the position of the water permeable plate 4. The filter screen 706 can filter some larger cutting debris, and at the same time, the porous magnetic attraction plate 705 can adsorb the fine metal debris in the water, facilitating the solid-liquid separation operation of the processing water, so that the processing water can be recycled, reducing the waste of water resources.

[0030] Furthermore, a fixing hole is opened on the front side of the workbench 1, and a collecting frame 707 is inserted into the inner wall of the fixing hole, and the position of the collecting frame 707 corresponds to the position of the strip frame 704. The water in the processing tank will eventually flow into the collecting frame 707, and the collecting frame 707 can be drawn out through the fixing hole, which is convenient for water recycling operations.

[0031] Working principle: first, place the mold at the center of the rectangular frame 5101 on the permeable plate 4. At this time, turn on the two first cylinders 5107 to move the two vertical clamps 5108 to the opposite sides, so that the front and back sides of the mold are clamped and fixed. At the same time, turn on the water pump 603. The water pump 603 transports the water in the water tank 601 to the processing tank through the connecting pipe 604, the water supply pipe 605 and the water outlet 606. When the water submerges the mold, start the cutting assembly 3 to make the wire-cutting wire generate an arc and cut the mold. When the two vertical clamps 5108 block the wire-cutting wire for processing, the two second cylinders 5206 are started and drive the two horizontal clamps 5207 to press the left and right sides of the mold. At this time, the two first cylinders 5107 drive the vertical clamps 5108 to retract, thereby quickly changing the clamping method of the mold, and there is no need for the staff to stop the machine and manually change the mold position for clamping. The operation is carried out continuously, which greatly improves the processing and cutting efficiency of the mold. After the mold processing is completed, the two electric push rods 701 are opened to move the two sealing plates 702 to both sides. At this time, the water in the processing tank flows downward to the collection frame 707. During the flow, the larger cutting waste in the processing tank will fall directly on the permeable plate 4, and some small debris will flow downward through the permeable plate 4. When it flows to the position of the strip frame 704, the filter screen 706 can filter some debris. At the same time, some metal debris will be adsorbed by the porous magnetic plate 705, and the filtered water flows into the collection frame 707, thereby completing the solid-liquid separation operation, facilitating the recycling of water and avoiding the waste of water resources. At the same time, the strip frame 704 can be pulled out of the slot, which is convenient for centralized processing of metal debris. At the same time, the filter screen 706 can also be replaced, which is more flexible.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
