Technical Field

[0001] The invention belongs to the technical field of metal cutting, and more particularly relates to a metal parts wire cutting device. Background Art

[0002] Wire cutting is a process that uses a continuously moving thin metal wire as an electrode to perform pulsed spark discharge cutting on the workpiece. This process is widely used in many fields such as mold manufacturing and mechanical processing. During the cutting process, it is also necessary to set up a coolant to remove the large amount of heat generated during the cutting process to avoid deformation of the parts. At the same time, the coolant can also remove the debris generated during the cutting process.

[0003] In the existing technology, in order to achieve the recycling of coolant, it is necessary to filter and separate the debris in the coolant; in the traditional method, a filter is often set at the drain port to intercept the debris, but the filter is easy to clog and needs to be replaced frequently, which requires the machine to be shut down for replacement, affecting processing efficiency.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or indirectly on the other element. It should be understood that the terms “length”, “width”, “upper”, “lower”, “front”, “back”, “top”, “bottom”, “inside”, “outside”, etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0041] Please also refer to Figures 1 to 6 The metal parts wire cutting device provided by the present invention is now described. The metal parts wire cutting device comprises a base 1, a separation box 2, a roller assembly 4 and a liquid collecting box 3; a workbench 11 is provided on the top surface of the base 1 for sliding; a downwardly concave drainage trough 12 is provided at one end of the workbench 11; the separation box 2 is provided at the bottom of the workbench 11; the top of the separation box 2 is connected to the drainage trough 12 in correspondence with the upper and lower parts; the bottom of the separation box 2 is provided with a liquid guide port 21 corresponding to the upper and lower parts of the drainage trough 12; the roller assembly 4 is placed in the separation box 2; the roller assembly 4 includes a rotating roller 42 provided at both ends of the drainage trough 12, and a roller 42 provided at both ends of the roller 42. A soft metal mesh 41 is correspondingly wound between the two rotating rollers 42; the outer edge of the soft metal mesh 41 extends horizontally over the wall of the drainage trough 12; the collecting tank 3 is placed at the bottom of the separation tank 2 and is connected to the liquid guide port 21 from top to bottom; wherein, the mixture formed by the coolant and chips enters the separation tank 2 through the drainage trough 12 and is filtered by the soft metal mesh 41. The liquid is discharged into the collecting tank 3 from the liquid guide port 21, and the chips remain on the soft metal mesh 41; when the rotating roller 42 rotates, the chips move with the soft metal mesh 41 to the rotating roller 42.

[0042] It should be noted that the soft metal mesh 41 has a certain toughness and can be wound around the corresponding rotating roller 42 .

[0043] It should be understood that the two rotating rollers 42 are defined as the first rotating roller 42 and the second rotating roller 42. Multiple layers of soft metal mesh 41 are wound around the first rotating roller 42. The multiple layers of soft metal mesh 41 are distributed in a mosquito coil-like manner, and one end extends under the drainage trough 12 and is fixed on the second rotating roller 42. When the soft metal mesh 41 placed under the drainage trough 12 is blocked, the second rotating roller 42 can be rotated to allow the blocked soft metal mesh 41 to be wound around the second rotating roller 42, and the winding layer of the soft metal mesh 41 on the first rotating roller 42 can be unfolded to re-extend under the drainage trough 12, thereby realizing the replacement of the soft metal mesh 41.

[0044] In addition, it should be understood that when too much swarf accumulates on the soft metal mesh 41, it will clog the soft metal mesh 41. When the soft metal mesh 41 rotates to the second rotating roller 42, some of the larger particles or accumulated upper chips will automatically fall below the second rotating roller 42, so the soft metal mesh 41 can be reused; however, there are still a small number of granular chips or lower-layer chips that may be clogged in the mesh of the soft metal mesh 41, so when the soft metal mesh 41 is used for the second time, its actual usage time is relatively short, and the more times it is recycled, the shorter the corresponding usage time of the soft metal mesh 41 will be, until it is completely clogged and the soft metal mesh 41 reel needs to be replaced.

[0045] Specifically, the workbench 11 has an upper slide 111 and a lower slide 112; the lower slide 112 is slidably connected to the base 1 along a moving direction perpendicular to the soft metal net 41, and a first driving mechanism 8 for driving the lower slide 112 to slide is provided between the lower slide 112 and the base 1, and the first driving mechanism 8 includes a first rotating screw and a first driving motor, and a belt transmission member; the first rotating screw is passed through between the enclosure at the top of the base 1 and the lower slide 112 along a moving direction perpendicular to the soft metal net 41, and the first rotating screw is threadedly connected to the lower slide 112; when the first driving motor drives the first rotating screw to rotate, the lower slide 112 moves on the first rotating screw; further, a first slide rail is provided on the base 1, and the lower slide 112 is slidably connected to the first slide rail.

[0046] In addition, the upper slide 111 is slidably connected to the lower slide 112 in a direction perpendicular to the first rotating screw, and a second driving mechanism 9 for driving the upper slide 111 to slide is provided between the upper slide 111 and the lower slide 112, and the second driving mechanism 9 includes a second rotating screw and a second driving motor; the second rotating screw is passed between the lower slide 112 and the upper slide 111 along a moving direction parallel to the soft metal net 41, and the second rotating screw is threadedly connected to the upper slide 111; when the second driving motor drives the second rotating screw to rotate, the upper slide 111 moves on the second rotating screw; further, a second slide rail is provided on the lower slide 112, and the upper slide 111 is slidably connected to the second slide rail.

[0047] Exemplarily, a positioning plate 13 is provided on the top of the workbench 11. The positioning plate 13 has a T-shaped structure. One end of the T-shaped positioning plate 13 extends to the metal wire, and a clamping member 14 is provided on the positioning plate 13. The clamping member 14 is used to clamp the parts to be processed.

[0048] Optionally, the clamping member 14 includes a Z-shaped clamp and a limiting bolt; one side of the Z-shaped clamp abuts against the positioning plate 13, and the other side extends above the part to be processed; the limiting bolt passes through the extended side of the Z-shaped clamp in the vertical direction and abuts against the part to be processed.

[0049] There are multiple groups of clamping members 14, which are arranged at intervals around the workpiece to be processed; preferably, there are two groups of clamping members 14, which are clamped on the upper and lower sides of the workpiece to be processed.

[0050] Specifically, the separation box 2 is a box-type structure with an open top, and the top of the separation box 2 is fixed to the bottom surface of the workbench 11. In order to conveniently represent the structure of the first partition 22 and the second partition 23 inside the separation box 2, the following text is used in the present application. Figure 2 The circumferential side wall of the separation box 2 is hidden, specifically the side wall close to the first drive assembly 5 is hidden.

[0051] The metal parts wire cutting device provided by the present invention is compared with the prior art. The scheme shown in the embodiment of the present application is that the separation box 2 is arranged at the bottom of the workbench 11 and can move with the workbench 11 so that the drainage trough 12 always corresponds to the metal soft mesh 41 up and down; the present application is provided with a roller assembly 4, which can filter the mixture formed by the coolant and chips through the metal soft mesh 41, so that the liquid is discharged into the collecting box 3 after passing through the drainage trough 12, the metal soft mesh 41, and the liquid guide port 21, while the chips are attached to the metal soft mesh 41; and when the rotating roller 42 rotates, the metal soft mesh 41 with the chips moves to the rotating roller 42, which can drive the chips away from the liquid guide port 21 and wrap the blocked metal soft mesh 41 around one of the rotating rollers 42. At the same time, a new metal soft mesh 41 is replaced to the bottom of the drainage trough 12. There is no need to stop the machine to replace the filter device, which can effectively ensure the efficiency of the cutting work, keep the working environment of the cutting device clean, and reduce interference with the cutting process.

[0052] See also Figure 4 In some possible embodiments, multiple groups of roller assemblies 4 are provided, and the multiple groups of roller assemblies 4 are arranged at intervals up and down, and the metal soft mesh 41 of each group of roller assemblies 4 corresponds to the drainage trough 12 up and down. Optionally, the moving directions of each two adjacent groups of metal soft meshes 41 are opposite; or, the moving directions of each two adjacent groups of metal soft meshes 41 are the same.

[0053] By making the moving directions of two adjacent groups of soft metal meshes 41 opposite to each other, the chips can be dispersed to the rotating rollers 42 at both ends, thereby achieving uniform distribution of the chips and avoiding large amounts of accumulation.

[0054] Multiple groups of roller assemblies 4 are arranged at intervals up and down, which can achieve multi-layer filtration. Different groups of metal soft meshes 41 can filter the mixture multiple times, further improving the filtration accuracy, more effectively separating the coolant and chips, ensuring the cleanliness of the coolant, and facilitating the stable operation of the cutting device.

[0055] Furthermore, the mesh size of the multi-layer soft metal mesh 41 is gradually reduced from top to bottom, and the multi-layer filtration disperses the chips step by step, reducing the filtration pressure of the top layer soft metal mesh 41 and the possibility of local blockage, thereby extending the service life of the soft metal mesh 41 and reducing equipment maintenance costs.

[0056] Preferably, two groups of roller assemblies 4 are provided, and the moving directions of the metal soft meshes 41 of the two groups of roller assemblies 4 are the same or opposite. The specific moving directions can be selectively set according to actual needs. Preferably, the moving directions of each two adjacent groups of metal soft meshes 41 are opposite.

[0057] See also Figure 2 and Figure 4 In some embodiments, a first driving assembly 5 is further provided in the separation box 2 , and a power output end of the first driving assembly 5 is power-connected to one of the rotating rollers 42 of each group of roller assemblies 4 .

[0058] By driving one of the rotating rollers 42 to rotate through the first driving assembly 5, the other rotating roller 42 can be driven by the soft metal mesh 41 to rotate synchronously, so that one rotating roller 42 can reel in the soft metal mesh 41 and the other rotating roller 42 can release the soft metal mesh 41, thereby realizing the replacement of the soft metal mesh 41 at the bottom of the drainage trough 12.

[0059] By uniformly driving each group of roller assemblies 4, the rotating rollers 42 cooperate with each other tacitly, which can more efficiently drive the movement of multiple groups of metal soft meshes 41, so that the chips are transported to the designated position in time, speeding up the speed of filtering and cleaning chips, and improving the working efficiency of the entire wire cutting device.

[0060] See also Figure 4 , exemplarily, the first driving assembly 5 includes multiple groups of first gears 51, multiple moving keys and a rotating driving member 53; multiple groups of first gears 51 correspond one to one with multiple groups of roller assemblies 4, and multiple first gears 51 are arranged correspondingly up and down in the vertical direction; the first gear 51 is fixedly connected to the adjacent rotating rollers 42 in each corresponding group of roller assemblies 4; multiple moving members 52 are arranged at intervals up and down in the vertical direction, and all extend along the moving direction of the soft metal mesh 41; each moving member 52 is provided with a group of first racks 521 on the upper and lower sides; the moving members 52 are all slidably connected in the separation box 2 along the moving direction of the soft metal mesh 41; the power output end of the rotating driving member 53 is connected to one of the rotating rollers 42 to drive the corresponding first gear 51 to rotate; wherein, a moving member 52 is passed through each two adjacent first gears 51, and the first rack 521 is meshed with the adjacent first gear 51 up and down; when one of the first gears 51 rotates, the other first gears 51 rotate synchronously driven by the first racks 521.

[0061] Specifically, the rotating driving member 53 can be a rotating motor or a manually driven rotating handle; the power output end of the rotating driving member 53 drives one of the first gears 51 to rotate, and the first gear 51 engages with the adjacent first rack 521 to make the first rack 521 slide, and drives the first rack 521 on the same moving member 52 to slide accordingly, thereby realizing the rotation of another adjacent first gear 51. Similarly, the synchronous rotation of multiple first gears 51 can be realized; each first gear 51 drives the rotating roller 42 fixedly connected to it to rotate, so that the metal soft mesh 41 can be replaced.

[0062] Furthermore, a guide column 24 extending along the moving direction of the metal soft net 41 is provided in the separation box 2, and a guide groove 522 suitable for the guide column 24 to pass through is provided in the moving part 52. When the first gear 51 rotates, the first rack 521 drives the moving part 52 to slide on the corresponding guide column 24.

[0063] The first drive assembly 5 adopts a gear rack transmission structure with a simple and compact structure. The multiple first gears 51, the moving member 52 and the first rack 521 cooperate with each other to achieve effective power transmission, a stable and reliable transmission process, reduce the probability of failure, and improve the reliability and stability of the equipment.

[0064] See also Figure 5 In some embodiments, two groups of first partitions 22 are arranged at intervals along the moving direction of the soft metal mesh 41 in the separation box 2, and the two groups of first partitions 22 divide the separation box 2 into a liquid flow chamber 25 in the middle and a chip storage chamber 26 at both ends of the liquid flow chamber 25; wherein, each first partition 22 is provided with a clearance groove 221 suitable for the soft metal mesh 41 to pass through, and two rotating rollers 42 are correspondingly arranged in the two chip storage chambers 26, and the soft metal mesh 41 is arranged in the liquid flow chamber 25, and both ends pass through the clearance groove 221 and are wound and fixed with the corresponding rotating rollers 42.

[0065] By providing a first partition 22, the separation box 2 is divided into a liquid flow chamber 25 and a chip storage chamber 26, thereby facilitating the separation of liquid and solid components. Even if the coolant and chips have their own independent flow and storage space in the separation box 2, it is convenient to manage the coolant and chips separately, thereby improving the efficiency of filtering and cleaning.

[0066] Optionally, the bottom wall of the separation box 2 corresponding to the bottom of the liquid flow chamber 25 is higher than the bottom wall of the separation box 2 corresponding to the chip storage chamber 26 to prevent the separated coolant from mixing with the chips.

[0067] Furthermore, two guide protrusions are provided on the soft metal mesh 41, which extend along the moving direction of the soft metal mesh 41, and a plurality of filter meshes are arranged in an array between the two guide protrusions; guide grooves 522 adapted to the guide protrusions are provided on the top and bottom groove walls of the give way groove 221, and when the soft metal mesh 41 moves, the guide protrusions slide in the guide grooves 522.

[0068] Furthermore, the bottom of the clearance groove 221 is flush with the bottom of the soft metal mesh 41 , and the top side of the clearance groove 221 is higher than the soft metal mesh 41 so that the chips can enter the chip storage cavity 26 .

[0069] See also Figure 5 For example, a longitudinally extending second partition 23 is further provided in the separation box 2, and the second partition 23 is arranged perpendicular to the two groups of first partitions 22; one side of the second partition 23 forms a closed side of the liquid flow cavity 25, and the other side and the wall of the separation box 2 accommodate the first drive assembly 5.

[0070] The longitudinally extending second partition 23 accommodates the first drive assembly 5 in a specific space, making the internal structure of the separation box 2 compact and the layout more reasonable, saving space and facilitating installation and use in a limited work area.

[0071] In addition, one side of the second partition 23 forms a closed side of the liquid flow cavity 25, which can prevent liquids such as coolant from entering the area where the first drive component 5 is located, avoid the erosion of the drive component by the coolant, protect the drive component, ensure its stable operation, and reduce failures and maintenance costs caused by the intrusion of coolant.

[0072] See also Figure 4 In some possible embodiments, the metal parts wire cutting device further includes two sets of scraping assemblies 6, which are correspondingly arranged on the outer sides of the two rotating rollers 42; the scraping assemblies 6 are used to scrape off the chips on the metal soft mesh 41.

[0073] As mentioned above, some large-sized chips fall under the action of gravity, and small-sized chips may be stuck in the mesh of the metal soft net 41. The scraping assembly 6 can scrape the chips on the metal soft net 41 in time to prevent the chips from accumulating too much on the metal soft net 41 and affecting the filtering effect.

[0074] It should be understood that timely cleaning of chips helps maintain the filtering performance of the metal soft mesh 41, ensures that the coolant can pass smoothly, maintains the normal operation of the cutting device, and at the same time ensures the cleanliness of the coolant, which is beneficial to the cutting quality of metal parts and reduces the impact of excessive impurities in the coolant on cutting accuracy and surface quality.

[0075] See also Figure 2 and Figure 4In some embodiments, the scraping assembly 6 includes a telescopic driving member 62 and multiple sets of scrapers 61; one end of the telescopic driving member 62 is fixed on the inner wall of the separation box 2, and the other end extends toward the roller assembly 4; one end of the multiple sets of scrapers 61 is fixed to the extended end of the telescopic driving member 62, and the other end extends to the outer peripheral wall of the rotating roller 42.

[0076] The telescopic driving member 62 can adjust the telescopic length of the scraper 61 according to actual needs to adapt to chips of different thicknesses or accumulation conditions.

[0077] Specifically, the telescopic drive member 62 drives multiple groups of scrapers 61 to extend and retract synchronously, thereby adjusting the distance between the scraper 61 and the rotating roller 42; it should be understood that when the metal soft mesh 41 is rolled up or released on the rotating roller 42, the outer metal soft mesh 41 is either close to or away from the extended end of the scraper 61. By adjusting the distance between the scraper 61 and the rotating roller 42, interference between the scraper 61 and the metal soft mesh 41 can be avoided, and the scraping effect of the scraper 61 can be ensured.

[0078] Optionally, the telescopic driving member 62 is one or more of a telescopic cylinder, a telescopic hydraulic cylinder or an electric telescopic rod.

[0079] One end of the scraper 61 extends to the outer peripheral wall of the rotating roller 42, which can effectively scrape off the chips on the soft metal mesh 41. This arrangement of the scraper 61 can accurately scrape off the chips at the rotating roller 42, ensuring that the chips can be smoothly separated from the soft metal mesh 41.

[0080] See also Figure 4 , exemplarily, the scraper 61 is an L-shaped plate; one side of the L-shaped plate is connected to the telescopic driving member 62, and the other side extends horizontally to the metal soft mesh 41 on the rotating roller 42.

[0081] The scraper 61 is an L-shaped plate, and its horizontally extending side can increase the contact area with the outer peripheral wall of the rotating roller 42, thereby more effectively scraping off the chips on the metal soft mesh 41 near the rotating roller 42. It should be understood that a larger scraping area helps to improve scraping efficiency and ensure that the chips are thoroughly removed.

[0082] In addition, the L-shaped plate structural design makes the scraper 61 more stable when scraping chips, and is not easy to shake or fall off, thereby enhancing the scraping effect, ensuring that the chips on the metal soft mesh 41 are completely scraped off, reducing residue, and improving the quality of filtering and cutting work.

[0083] Furthermore, a chip removal hole 611 extending vertically is provided on the horizontally extending side of the scraper 61 so as to guide the scraped chips downward from the chip removal hole 611 .

[0084] See also Figure 5Optionally, the scraping and conveying assembly 6 also includes a nozzle 7 and a blower; the nozzle 7 is arranged on the top wall of the separation box 2 and corresponds to the scraper 61 above and below; the air inlet end of the nozzle 7 is used to communicate with the air supply end of the blower to blow off the chips accumulated on the scraper 61.

[0085] The nozzle 7 is connected to the blower to blow off the chips accumulated on the scraper 61, which can completely remove the chips remaining on the scraper 61, thereby further ensuring the cleanliness of the scraping assembly 6, avoiding the residual chips from adhering to the metal soft mesh 41 again, affecting the filtering effect, and ensuring the efficient and stable operation of the entire wire cutting device.
