Description

Technical Field

[0001] The utility model belongs to the technical field of wire cutting guide wire eye molds, and specifically relates to a wire cutting guide wire eye mold with coolant storage. Background Art

[0002] A wire cutting machine tool is an electro-discharge machining tool. Its basic working principle is to use a continuously moving thin metal wire (called tungsten-molybdenum wire) as an electrode to perform pulsed spark discharge on the workpiece to erode metal and cut it into shape. This kind of machine tool is mainly used for processing various workpieces with complex shapes and precision and small size, and is one of the indispensable equipment in the manufacturing industry.

[0003] In the tungsten-molybdenum wire cutting process, the wire cutting guide wire eye mold is a very important accessory. The wire cutting guide wire eye mold can reduce vibration and impact during processing, which helps to improve the processing accuracy and surface quality. It can also reduce the splashing and scattering of the processing fluid, avoid the adverse effects of the processing fluid on the processed parts, and further ensure the processing accuracy.

[0004] During the working process of wire cutting, it is necessary to use coolant to cool the tungsten-molybdenum wire. In the prior art, the coolant is introduced into the guide wire eye mold and then discharged from the guide wire eye mold to the tungsten-molybdenum wire for cooling. However, when the existing commercially available guide wire eye molds guide the coolant, there are problems with poor cooling effect on the tungsten-molybdenum wire. Therefore, a wire cutting guide wire eye mold with coolant storage is proposed. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a wire cutting guide wire eye mold with coolant storage that can overcome or at least partially solve the above problems.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a wire cutting guide wire eye mold with coolant storage, including: a housing installed with a wire guide tube, the wire guide tube is used for threading the guide wire, and a cavity is provided in the housing; a water inlet hole is circumferentially opened on the housing, and the water inlet hole is communicated with the cavity to introduce external coolant into the cavity; a coolant storage assembly is connected to the housing, and the coolant storage assembly has a water storage cavity for covering the guide wire with the coolant.

[0007] Preferably, a recessed area is opened on the outer periphery of the housing, and the water inlet hole is opened in the recessed area.

[0008] Preferably, external threads are opened on both sides of the housing located in the recessed area.

[0009] Preferably, a counterbore is opened at one end of the housing, and the end block at one end of the wire guide tube is located in the counterbore.

[0010] Preferably, the coolant storage assembly includes a connecting block and a water storage cylinder which are connected to each other. The connecting block is connected in a counterbore at one end of the housing. The water storage cavity is a cylindrical water storage cavity inside the water storage cylinder, and the cylindrical water storage cavity communicates with the cavity.

[0011] Preferably, the coolant storage assembly includes a connecting block and a water storage cylinder which are connected to each other. The connecting block is connected in a counterbore at one end of the housing. The water storage cavity is a cylindrical water storage cavity inside the water storage cylinder, and the cylindrical water storage cavity communicates with the cavity; a end cover is further connected to the open end of the water storage cylinder away from the connecting block, and a perforation is formed in the middle of the end cover.

[0012] Preferably, the coolant storage assembly includes a connecting block and a conical cylinder which are connected to each other. The connecting block is connected in a counterbore at one end of the housing. The water storage cavity is a conical water storage cavity inside the conical cylinder, and the conical water storage cavity communicates with the cavity. A wire threading hole is formed at one end of the conical water storage cavity.

[0013] Furthermore, openings are formed on the outer periphery of the wire guiding cylinder, and a conical through groove is formed in the wire guiding cylinder. The openings are used to introduce the coolant in the cavity into the conical through groove.

[0014] Furthermore, a first inclined surface is formed on the outer periphery of the wire guiding cylinder at one end away from the end block, and a second inclined surface is formed in the inner diameter of the connecting block. A conical flow guiding area is formed between the first inclined surface and the second inclined surface, and the conical flow guiding area faces the water storage cavity.

[0015] Furthermore, a slit is formed in the coolant storage assembly.

[0016] After adopting the above technical solution, the present utility model has the following beneficial effects compared with the prior art: through the formed water storage cavity, the present utility model can accumulate a large amount of coolant, and during the continuous water inlet process of the water inlet hole, the coolant in the water storage cavity is replaced. The wire passes through the water storage cavity, so the coolant can coat the wire located in the water storage cavity, enabling a large amount of coolant to contact the wire, thereby efficiently cooling and cooling the wire, better maintaining the cooling and cleaning effects on the wire, reducing various wire breaking methods caused by overheating during the wire discharge process, and improving the service life and cutting efficiency of the wire in wire electrical discharge machining;

[0017] When the coolant enters the cavity through the water inlet hole, a part of the coolant will enter the conical through groove again through the openings. The narrow end of the conical through groove is located at the end block; when the coolant enters the conical through groove through the openings, due to the narrow inner diameter of the conical through groove, the coolant will form friction on the wire, having a cleaning effect on the wire surface and also producing a certain polishing effect, making the wire more stable in the discharge state;

[0018] When the coolant in the cavity enters the water storage cavity, it will pass through the conical diversion area. Since the width of the conical diversion area is small, the coolant will be pressurized when entering the water storage cavity, which makes the coolant form a conical water column towards the axis of the housing. This can further wash and polish the wire passing through, making the wire more stable during the discharge state;

[0019] The setting of the slit can facilitate the disassembly and installation of the coolant storage component when the housing has been installed on the wire seat. It can quickly complete the disassembly and installation of the coolant storage component without having to disassemble the wire from the machine tool.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0032] Embodiment 1: Refer to Figures 1 - 8 , a wire cutting guide wire eye mold for coolant storage, comprising: a housing 1 installed with a wire guide tube 2, the wire guide tube 2 is used to pass the wire, and a cavity 16 is arranged in the housing 1; a water inlet hole 15, circumferentially opened on the housing 1, the water inlet hole 15 is communicated with the cavity 16, and is used to introduce external coolant into the cavity 16; a coolant storage assembly, connected to the housing 1, the coolant storage assembly has a water storage cavity, and is used to make the coolant cover the wire.

[0033] When the device is in use, the housing 1 is installed on the wire seat of the wire cutting machine tool. By passing the wire through the wire guide tube 2 and the coolant storage assembly, during the use process, the coolant enters the cavity 16 through the water inlet hole 15 and enters the coolant storage assembly. Since the water storage cavity of the coolant storage assembly has a certain length, a large amount of coolant can be accumulated in the water storage cavity. During the continuous water inlet process of the water inlet hole 15, the coolant in the water storage cavity is replaced. The wire passes through the water storage cavity, so the coolant can cover the wire located in the water storage cavity, so that a large amount of coolant can contact the wire, thereby efficiently cooling and cooling the wire, and can better maintain the cooling and cleaning effects on the wire, reducing various wire breakage methods caused by overheating during the wire discharge process, and improving the service life and cutting efficiency of the wire in electric discharge wire cutting.

[0034] And this device is suitable for being installed in the upper wire seat and the lower wire seat of the wire cutting machine tool.

[0035] A concave area 11 is opened on the outer periphery of the housing 1, and the water inlet hole 15 is opened in the concave area 11. The setting of the concave area 11 can facilitate the coolant to first enter the concave area 11 and then enter the cavity 16 of the housing 1 through the water inlet hole 15 when the housing 1 is installed on the wire seat.

[0036] External threads 12 are provided on both sides of the recessed area 11 on the housing 1. The provided external threads 12 can facilitate the quick and stable connection of the housing 1 with the upper wire seat and the lower wire seat.

[0037] Furthermore, the outer shape of the housing 1 is composed of a hexahedron 13 at one end and a cylinder. The recessed area 11 is opened on the outer periphery of the cylinder. The recessed area 11 is recessed into the outer periphery of the cylinder and is annular. The setting of the hexahedron 13 can facilitate the use of tools such as wrenches to tighten or disassemble the housing 1;

[0038] A wear-resistant guide block 20 is provided on the end block 21 of the wire guide tube 2 to improve the wear resistance of the wire guide tube 2.

[0039] Example 2: Refer to Figure 3 , a wire cutting wire guide eye mold for coolant storage, which is basically the same as Example 1. Further, a counterbore 14 is opened at one end of the housing 1. The end block 21 at one end of the wire guide tube 2 is located in the counterbore 14. The counterbore 14 is located at the end of the cylinder of the housing 1 away from the hexahedron 13 for installing the wire guide tube 2 and restricting the installation position of the wire guide tube 2.

[0040] Example 3: Refer to Figure 2 、 Figure 3 、 Figure 4 , a wire cutting wire guide eye mold for coolant storage, which is basically the same as Example 2. Further, the coolant storage assembly includes a connecting block 3 and a water storage cylinder 31 connected to each other. The connecting block 3 is connected in a counterbore 17 at one end of the housing 1. The water storage cavity is a cylindrical water storage cavity 32 in the water storage cylinder 31. The cylindrical water storage cavity 32 is communicated with the cavity 16;

[0041] The inner diameter of the counterbore 17 is larger than the inner diameter of the cavity 16, and internal threads are provided on the inner wall of the counterbore 17. The connecting block 3 is installed in the counterbore 17 by means of threaded connection;

[0042] The water storage cylinder 31 has a certain length;

[0043] Preferably, the height of the water storage cylinder 31 is the same as the length of the housing 1.

[0044] Example 4: Refer to Figure 5 、 Figure 6 , a wire cutting wire guide eye mold for coolant storage, which is basically the same as Example 2. Further, the coolant storage assembly includes a connecting block 3 and a water storage cylinder 31 connected to each other. The connecting block 3 is connected in a counterbore 17 at one end of the housing 1. The water storage cavity is a cylindrical water storage cavity 32 in the water storage cylinder 31. The cylindrical water storage cavity 32 is communicated with the cavity 16; A end cover 4 is also connected to the open end of the water storage cylinder 31 away from the connecting block 3, and a perforation 41 is opened in the middle of the end cover 4;

[0045] The inner diameter of the counterbore 17 is larger than the inner diameter of the cavity 16, and an internal thread is provided on the inner wall of the counterbore 17. The connecting block 3 is installed in the counterbore 17 by means of threaded connection;

[0046] The water storage cylinder 31 has a certain length;

[0047] Preferably, the height of the water storage cylinder 31 is the same as the length of the housing 1;

[0048] By connecting an end cover 4 to one end of the water storage cylinder 31, the size of the opening at the end of the water storage cylinder 31 away from the connecting block 3 can be reduced, thereby reducing the discharge speed of the coolant, further improving the coating effect of the coolant on the wire guide, and improving the cooling and cleaning effects on the wire guide;

[0049] And connecting an end cover 4 to one end of the water storage cylinder 31 is particularly suitable when installed on the wire loading base. One end of the water storage cylinder 31 is downward, which makes the size of the opening end of the water storage cylinder 31 connected with the end cover 4 further reduced. When installed on the wire loading base, the residence time of the coolant in the water storage cavity can be further increased, so that the wire guide is further coated with the coolant;

[0050] The connection method between the end cover 4 and the water storage cylinder 31 can adopt threaded connection, and the set screw penetrates through the outer wall of the water storage cylinder 31 to abut against the end cover 4.

[0051] Example 5: Refer to Figure 5 、 Figure 6 A wire cutting wire guide eye mold for coolant storage is basically the same as that in Example 2. Further, the coolant storage assembly includes a connected connecting block 3 and a conical cylinder 30. The connecting block 3 is connected in a counterbore 17 at one end of the housing 1. The water storage cavity is a conical water storage cavity 301 inside the conical cylinder 30. The conical water storage cavity 301 is communicated with the cavity 16, and a wire threading hole 302 is formed at one end of the conical water storage cavity 301;

[0052] The inner diameter of the counterbore 17 is larger than the inner diameter of the cavity 16, and an internal thread is provided on the inner wall of the counterbore 17. The connecting block 3 is installed in the counterbore 17 by means of threaded connection;

[0053] The water storage cylinder 31 has a certain length;

[0054] Preferably, the height of the water storage cylinder 31 is the same as the length of the housing 1;

[0055] The conical water storage cavity 301 formed inside the conical cylinder 30 can reduce the opening at the end of the conical cylinder 30 away from the connecting block 3, which reduces the flow rate of the coolant discharged from the conical water storage cavity 301. As a result, more coolant can be retained in the conical water storage cavity 301, further coating the wire guide, and thus improving the cooling effect;

[0056] Moreover, the solution of this embodiment is particularly suitable for being installed in the upper wire seat, which can further effectively prevent the coolant from flowing out of the conical water storage cavity 301 quickly under the action of gravity when the coolant enters the conical water storage cavity 301;

[0057] Furthermore, the outer shape of the conical cylinder 30 can be a cylinder.

[0058] Embodiment 6: Refer to Figure 4 , a wire cutting guide wire eye mold for storing coolant, which is basically the same as Embodiment 3, Embodiment 4, and Embodiment 5. Further, an opening 22 is provided on the outer periphery of the wire guide cylinder 2, and a conical through groove 24 is provided in the wire guide cylinder 2. The opening 22 is used to introduce the coolant in the cavity 16 into the conical through groove 24;

[0059] After the coolant enters the cavity 16 through the water inlet hole 15, a part of the coolant will enter the conical through groove 24 again through the opening 22, and the narrow end of the conical through groove 24 is located at the end block 21;

[0060] When the coolant enters the conical through groove 24 through the opening 22, due to the narrow inner diameter of the conical through groove 24, the coolant will form friction on the guide wire, which has a cleaning effect on the surface of the guide wire and will also produce a certain polishing effect, making the guide wire more stable in the discharge state.

[0061] Embodiment 7: Refer to Figure 3 , a wire cutting guide wire eye mold for storing coolant, which is basically the same as Embodiment 6. Further, a first inclined surface 23 is provided on the outer periphery of one end of the wire guide cylinder 2 away from the end block 21, and a second inclined surface 33 is provided on the inner diameter of the connecting block 3. A conical flow guiding area 34 is formed between the first inclined surface 23 and the second inclined surface 33, and the conical flow guiding area 34 faces the water storage cavity;

[0062] When the coolant in the cavity 16 enters the water storage cavity, it will pass through the conical flow guiding area 34. Since the width of the conical flow guiding area 34 is small, the coolant will be pressurized when entering the water storage cavity, making the coolant form a conical water column towards the axis of the housing 1, which can further wash and polish the passing guide wire, making the guide wire more stable in the discharge state and further reducing various wire breakage methods caused during the discharge of the guide wire, improving the service life and cutting efficiency of the wire electrode for electrical discharge wire cutting.

[0063] Embodiment 8: Refer to Figure 1 、 Figure 5 、 Figure 7 , a wire cutting guide wire eye mold for storing coolant, which is basically the same as Embodiment 7. Further, a slit 300 is provided on the coolant storage assembly;

[0064] The provision of the slit 300 facilitates the disassembly and installation of the coolant storage assembly without having to remove the wire guide from the machine tool when the housing 1 is already installed on the wire seat, enabling quick completion of the disassembly and installation of the coolant storage assembly.

[0065] Specifically, align the slit 300 with the wire guide so that the wire guide passes through the slit 300, thereby allowing the wire guide to enter the water storage chamber of the coolant storage assembly. Subsequently, screw the connecting block 3 of the coolant storage assembly into the counterbore 17 of the housing 1 to complete the installation or disassembly of the coolant storage assembly.

[0066] Furthermore, when the coolant storage assembly is provided with a slit 300, the fixing method for the end cap 4 in the coolant storage assembly can also be to sleeved a hoop on the outer periphery of the water storage cylinder 31. By tightening the hoop around the water storage cylinder 31 and using the contraction of the slit 300, the end cap 4 is clamped onto the water storage cylinder 31.

[0067] Furthermore, the material of the coolant storage assembly is alloy metal, plastic, rubber, wood, ceramic, glass or stone, preferably alloy metal, which is durable.

[0068] The water storage chamber formed by the present utility model can accumulate a large amount of coolant. During the continuous water inlet process through the water inlet hole 15, the coolant in the water storage chamber is replaced. Since the wire guide penetrates the water storage chamber, the coolant can cover the wire guide located in the water storage chamber, enabling a large amount of coolant to come into contact with the wire guide, thereby efficiently cooling and cooling down the wire guide, better maintaining the cooling and cleaning effects on the wire guide, reducing various wire breakage methods caused by overheating during the wire discharge process, and improving the service life and cutting efficiency of the wire electrode for electrical discharge wire cutting.

[0069] The above are only the preferred embodiments of the present utility model and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art of the present utility model, without departing from the scope of the technical solution of the present utility model, may make some modifications or equivalent variations using the technical content prompted above. However, any simple modification, equivalent variation and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the scope of the present utility model.
