Description

Technical Field

[0001] The invention belongs to the technical field of slow-wire cutting equipment, and in particular relates to a slow-wire cutting equipment. Background Art

[0002] The wire cutting machine uses a continuously moving thin copper wire as an electrode, generates a temperature of more than 6000 degrees through pulsed spark discharge, removes metal and cuts into workpieces. Its processing accuracy can reach micron level, with the advantages of high precision and high surface finish, and is suitable for precision processing industry.

[0003] When cutting a workpiece, the slow wire cutting uses a continuously moving thin copper wire to perform pulse spark discharge on the workpiece, generating high temperature to erode the metal, and thus cut into shape. There is a gap between the thin copper wire and the workpiece, and the metal is removed by continuous discharge. In actual use, in order to dissipate the heat of the workpiece, the workpiece is immersed in coolant for processing. Since oxide scale and carbon slag will be generated on the workpiece during processing, these oxide scales and carbon slag will change the discharge gap between the thin copper wire and the workpiece, resulting in poor discharge state and excessively high local temperature of the thin copper wire, which often causes wire breakage.

[0004] There are few protective measures for thin copper wire in the prior art. Once the wire breaks during the cutting process, it will cause the trouble of rewinding the wire, which not only wastes time, but also leaves wire break marks on the workpiece, affecting the processing quality, and even causing the workpiece to be scrapped in severe cases.

[0034] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] like Figure 1 and Figure 2 As shown, a slow wire cutting device in one embodiment of the present invention includes a body 1, on which a liquid reservoir is provided, and the liquid reservoir contains a coolant. A mobile frame 2 is slidably connected to the body 1, and multiple sets of guide wheels 11 are installed on the body 1 and the mobile frame 2. Specifically, a workpiece is placed in the liquid reservoir, and a copper wire roll is rotatably connected to the body 1. The thin copper wire on the copper wire roll is guided by multiple sets of guide wheels 11 and is in a vertical state to perform electric cutting on the workpiece in the liquid reservoir.

[0036] When cutting the workpiece, oxide scale and carbon slag will be generated, which will cause the discharge gap between the thin copper wire and the workpiece to change continuously, resulting in the thin copper wire breaking.

[0037] In order to solve the above problems, Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, a fixed plate 3 is welded on the mobile frame 2, and the fixed plate 3 moves on the machine body 1 following the mobile frame 2. A connecting block 4 is welded on the front panel of the fixed plate 3, and a protective column 41 is plugged into the connecting block 4. A through groove 4101 is provided at the center of the column of the protective column 41, and the through groove 4101 runs through the protective column 41. A second water guide groove 412 is provided on the lower end surface of the protective column 41, and the second water guide groove 412 is located between the outer wall of the protective column 41 and the outer groove wall of the through groove 4101. A water through hole 4102 connected to the second water guide groove 412 is provided on the outer wall of the protective column 41, and a first water guide groove 401 matching the water through hole 4102 is provided on the connecting block 4, and a first water pipe 51 is plugged into the first water guide groove 401, and is inserted into the water through hole 4102 and connected to the second water guide groove 412, and a water pump 5 is welded to the end of the first water pipe 51 away from the connecting block 4.

[0038] Specifically, the thin copper wire guided by the guide wheel 11 penetrates into the through groove 4101, and the thin copper wire passing through the through groove 4101 discharges electricity with the workpiece, thereby cutting the workpiece. At this time, the water pump 5 is started, and the water pump 5 outputs the coolant into the first water pipe 51, and flows into the second water guide groove 412 through the first water pipe 51. Because the flow rate of the coolant entering the second water guide groove 412 remains unchanged, the volume of the second water guide groove 412 is smaller than the volume of the first water pipe 51, and the flow rate of the coolant sprayed out from the notch of the second water guide groove 412 is accelerated, forming a protective column, which can wash away the oxide scale and carbon residue generated on the workpiece, keep these oxide scales and carbon residue away from the thin copper wire and the workpiece, ensure that the discharge gap between the thin copper wire and the workpiece remains unchanged, and protect the thin copper wire. At the same time, the coolant sprayed from the second water guide groove 412 can quickly exchange heat with the coolant in the liquid storage tank, so that the temperature of the thin copper wire is further reduced, the heat dissipation effect of the thin copper wire is accelerated, and the thin copper wire is prevented from breaking.

[0039] Furthermore, a second water pipe 52 is welded to the water pump 5, and the end of the second water pipe 52 away from the water pump 5 is detachably connected to the filter 7. A third water pipe 71 is integrally formed on the filter 7, and the end of the third water pipe 71 away from the filter 7 is inserted into the liquid reservoir of the body 1. Specifically, since the water pump 5 continuously outputs coolant into the second water guide groove 412 during operation, excessive liquid in the liquid reservoir will overflow. The filter 7 continuously extracts the coolant in the liquid reservoir for filtration, and the filtered coolant enters the water pump 5, and is pressurized by the water pump 5 to flow into the second water guide groove 412, so that the volume of the coolant in the liquid reservoir can be kept unchanged. At the same time, there are no impurities in the coolant after being filtered by the filter 7, and the surface contamination of the thin copper wire can be prevented, thereby ensuring the conductivity between the electrode wire and the workpiece and improving the quality of the workpiece.

[0040] Furthermore, a second air guide groove 413 is provided on the lower end surface of the protective column 41, and the second air guide groove 413 is located between the groove wall of the second water guide groove 412 and the groove wall of the through groove 4101. A vent hole 4103 connected to the second air guide groove 413 is provided on the protective column 41, and a first air guide groove 402 matching the vent hole 4103 is provided on the connecting block 4, and an air pipe 61 is inserted into the first air guide groove 402, and an end of the air pipe 61 away from the connecting block 4 is connected to the air pump 6. Among them, the second water guide groove 412 and the second air guide groove 413 are both annular, and the groove bottom wall of the second water guide groove 412 is lower than the groove bottom wall of the second air guide groove 413. The second water guide groove 412 and the second air guide groove 413 are not connected to each other, which can prevent the protective gas in the second air guide groove 413 from flowing into the second water guide groove 412.

[0041] Specifically, the air pump 6 is connected to a protective gas. When the thin copper wire cuts a workpiece, the air pump 6 starts to compress the protective gas, and transmits it to the second air guide groove 413 through the air pipe 61. The protective gas is ejected from the notch of the second air guide groove 413 to form a virtual air column, thereby further isolating the oxide scale and carbon slag generated on the workpiece, further protecting the thin copper wire, and making the working state of the thin copper wire more stable. The protective gas can also stabilize the arc and reduce the fluctuation of the arc, thereby improving the cutting efficiency and cutting accuracy.

[0042] At the same time, the protective gas can isolate the air and prevent the thin copper wire from contacting with the oxygen in the coolant, thereby preventing the thin copper wire from oxidizing, ensuring that the thin copper wire does not undergo oxidation reaction, improving the secondary utilization rate of the thin copper wire, and reducing processing costs.

[0043] like Figure 5 and Figure 6 As shown, in order to fix the protective column 41, the water hole 4102 and the air hole 4103 on the protective column 41 are aligned with the first water guide groove 401 and the first air guide groove 402 on the connecting block 4. A fixing pipe 42 is integrally formed on the connecting block 4, and a slot 421 is formed on the upper end surface of the fixing pipe 42. The protective column 41 passes through the fixing pipe 42, and a protrusion 411 matching the slot 421 is integrally formed on the tube wall of the protective column 41.

[0044] Specifically, the protective column 41 is inserted into the fixing tube 42, and the protrusion 411 is aligned with the slot 421. When the protrusion 411 is inserted into the slot 421 and the lower panel of the protrusion 411 is in contact with the bottom wall of the second water guide groove 412, the water hole 4102 and the air hole 4103 can be aligned with the first water guide groove 401 and the first air guide groove 402 on the connecting block 4. In this way, even if the protective column 41 is damaged, a new protective column 41 can be quickly installed on the connecting block 4.

[0045] In order to keep the thin copper wire in a taut state at all times and prevent it from bending, Figure 2 and Figure 3 As shown, a first slide groove 21 is provided on the movable frame 2 , and the first slide groove 21 is between the two guide wheels 11 . A pressure wheel 22 is slidably connected in the first slide groove 21 .

[0046] Specifically, the pressing wheel 22 presses on the thin copper wire between two adjacent guide wheels 11. When the thin copper wire bends, the pressing wheel 22 slides downward in the first slide groove 21 under the action of gravity, and the weight of the pressing wheel 22 can keep the thin copper wire in a taut state.

[0047] like Figure 3 and Figure 4 As shown, in order to fix the workpiece, a clamping assembly is also installed in the machine body 1. The clamping assembly includes a pair of guide rails 8, and the pair of guide rails 8 are welded and connected to the opposite pool walls of the liquid storage tank. A pair of electronic sliders 81 are slidably connected to the guide rails 8, and a locking block 9 is integrally formed on the electronic slider 81, and a bearing plate 93 is integrally formed on the side wall of the locking block 9. A second slide groove 91 and a third slide groove 92 are provided on the locking block 9, and the second slide groove 91 and the third slide groove 92 are connected, and the bottom wall of the third slide groove 92 is in contact with the upper end surface of the bearing plate 93. A pair of clamping blocks 94 are slidably connected in the second slide groove 91 and the third slide groove 92, and a lead screw 95 is threadedly connected to the pair of clamping blocks 94, and a rotary motor 96 is installed on the lead screw 95.

[0048] Specifically, the pair of clamping blocks 94 are provided with internal threads matching the lead screw 95, and the internal threads on the pair of clamping blocks 94 rotate in opposite directions. When the lead screw 95 rotates clockwise, the pair of clamping blocks 94 approach each other. When the lead screw 95 rotates counterclockwise, the pair of clamping blocks 94 move away from each other.

[0049] When clamping a workpiece, first input the width of the workpiece to the machine body 1. After receiving the command, the electronic slider 81 moves on the guide rail 8 so that the distance between the pair of locking blocks 9 matches the size of the workpiece. At this time, the workpiece can be placed on the carrier plate 93, and the carrier plate 93 on the pair of locking blocks 9 can drag the workpiece. Then input the start command to the machine body 1 again, and the electronic sliders 81 approach each other again to clamp the workpiece. At the same time, the rotary motor 96 starts, driving the pair of lead screws 95 to approach each other, so that the four side walls of the workpiece can be clamped.

[0050] Furthermore, the clamping block 94 is concave, and the part of the clamping block 94 that slides on the supporting plate 93 is the clamping part. Since the lower panel of the clamping part of the clamping block 94 fits with the upper panel of the supporting plate 93, the weight of the clamping block 94 is pressed on the supporting plate 93, which will not generate additional stress on the lead screw 95. It can protect the lead screw 95 and prevent the lead screw 95 from bending due to long-term use.

[0051] Furthermore, the distance between the lower end surface of the pair of guide rails 8 and the bottom of the liquid reservoir is 15-20 cm, and the second chute 91 provided on the locking block 9 also penetrates the upper and lower end surfaces of the locking block 9. The oxide scale and carbon residue generated when the thin copper wire cuts the workpiece will float in the coolant. These substances have a greater density than the coolant and will sink to the bottom of the liquid reservoir. In the process of the oxide scale and carbon residue sinking to the bottom, they can pass through the second chute 91, preventing the oxide scale and carbon residue from falling into the second chute 91 and making it difficult to clean.

[0052] Because the bearing plate 93 is outside the side wall of the locking block 9, the oxide scale and carbon residue falling on the bearing plate 93 are easy to clean without wasting too much labor. At the same time, because the guide rail 8 is at a certain distance from the bottom of the liquid reservoir, when cleaning the bottom of the liquid reservoir, the oxide scale and carbon residue will not be blocked by the guide rail 8 and the locking block 9, which is convenient for cleaning and maintaining the liquid reservoir.

[0053] When in use, first fix the workpiece on the clamping assembly, and then start the machine body 1. At this time, the multiple groups of guide wheels 11 rotate, and the thin copper wire cuts the workpiece. When the thin copper wire cuts the workpiece, the water pump 5 continuously outputs the coolant, and the coolant output by the water pump 5 is transmitted to the second water guide groove 412 after passing through the first water pipe 51, and is sprayed from the notch position of the second water guide groove 412 to form a protective column, thereby protecting the thin copper wire. It can also wash away the oxide scale and carbon slag on the workpiece, keep these oxide scales and carbon slag away from the thin copper wire, ensure the discharge gap between the thin copper wire and the workpiece, and protect the thin copper wire. Furthermore, it can also speed up the flow rate of the coolant around the thin copper wire, so that the temperature of the thin copper wire is further reduced, accelerate the heat dissipation effect of the thin copper wire, and prevent the thin copper wire from breaking.

[0054] Compared with the prior art, the slow-wire cutting equipment of the present invention can effectively protect the thin copper wire when cutting the workpiece, preventing the oxide scale and carbon slag generated during the workpiece cutting process from changing the discharge gap between the thin copper wire and the workpiece, thereby ensuring a stable discharge state between the thin copper wire and the workpiece, and effectively preventing the thin copper wire from breaking due to changes in the discharge gap when cutting the workpiece, avoiding the scrapping of the workpiece, and thus helping to improve the processing quality and work efficiency.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0056] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
