Description

Technical Field

[0001] The invention relates to the field of metal processing, in particular to a wire cutting device for processing metal parts. Background Art

[0002] Wire cutting is an electrical machining method that uses metal wire (usually molybdenum wire or copper wire) as an electrode to cut the workpiece under the action of electric sparks. Its basic principle is to use the heat energy generated by electric spark discharge to cut the workpiece, and to achieve the machining of the workpiece by controlling the motion trajectory of the electrode wire. There is no significant mechanical chip force during the machining, which is suitable for machining conductive or semi-conductive materials and realizing the production of complex parts. It has high machining accuracy, generally reaching ±0.01mm, and the surface roughness can reach Ra1.6μm.

[0003] Wire cutting has been widely used in various fields, especially in the mechanical processing industry. It can process some pipe fittings or valve components and cut high-precision cut surfaces on the components. These components are generally used in more harsh environments, such as some high-pressure and high-temperature oil extraction environments. High-precision cut surfaces can provide safety for oil extraction.

[0004] Wire cutting processing has been widely used, but the current wire cutting processing equipment has limitations. When the workpiece is being processed, there are multiple cutting processing points on a component, and the current operation method generally fixes the workpiece while the cutting wire moves, that is, the cutting wire is transferred from one processing point to another, and this method has an adverse effect on accuracy. The wire cutting machine has many parts, and not only the stable transmission of the cutting wire itself, the stable release of the cutting wire by the release wheel, and the stable winding of the cutting wire by the winding wheel must be considered, but also the transfer of the cutting wire from one processing point to another must be considered, which requires the use of parts that can realize displacement. Furthermore, the wire cutting machine is mounted above the processing table, and the wire cutting machine plus the displacement parts are relatively bulky, which has an adverse effect on the displacement accuracy.

[0005] At the same time, the subsequent wire cutting machine body maintenance or replacement of the cutting wire needs to be moved up and reset, away from the processing table and the workpiece. At this time, the wire cutting machine body is in a relatively high position, and the maintenance line of sight and operation angle will cause troubles.

[0045] A plurality of lower pressing plates 6 are arranged above the base plate 3, and a distance of a width of a giving way groove 5 is set between two adjacent lower pressing plates 6, and both ends of each lower pressing plate 6 are vertically connected to both sides of the base 2, and a plurality of arc grooves 7 are provided on the lower surface of each lower pressing plate 6, and the arc grooves 7 are arranged one by one corresponding to the placement grooves 4;

[0046] A cutting line 8 is provided above the lower pressing plate 6, one end of the cutting line 8 is wound around the release wheel, and the other end of the cutting line 8 is wound around the winding wheel;

[0047] In this embodiment, the lifting platform 1 is driven by a lifting assembly, and the lifting assembly includes a vertical screw rod 9 and a motor for driving the vertical screw rod 9 to rotate. The vertical screw rods 9 are respectively arranged at the corners of the lifting platform 1 to drive the lifting platform 1 to move up and down.

[0048] A groove for the base 2 to slide is provided on the surface of the lifting platform 1, and the groove is arranged along the transverse direction of the lifting platform 1. A transverse screw rod 10 is arranged in the groove, and a motor for driving the transverse screw rod 10 to rotate is arranged at the end of the lifting platform 1;

[0049] In this embodiment, a metal part processing wire cutting device is designed, which is suitable for processing a rod-shaped workpiece 101. One end of the workpiece 101 is inserted from one side of the lower pressing plate 6, and the workpiece 101 is inserted into the space between the placement groove 4 and the arc groove 7. The workpiece 101 is stably seated in the placement groove 4 by its own gravity, and then the horizontal screw rod 10 is driven to rotate, and the bottom plate moves along the horizontal direction of the lifting platform 1, and the processing point on the workpiece 101 is moved to the position below the cutting line 8, and then the vertical screw rod 9 is driven to rotate, and the processing point on the workpiece 101 gradually moves up, and at the same time, the cutting line 8 also starts to run and cuts the processing point;

[0050] In this embodiment, the workpiece 101 is used as a movable part and the cutting line 8 is used as a fixed part. The cutting line 8 can process multiple processing points by simply moving the base plate and the lifting platform 1, and the components for realizing the displacement of the processing points are installed on the lifting platform 1 and the base 2, that is, the vertical screw rod 9, the horizontal screw rod 10, and the motor components are installed on the lifting platform 1 and the base 2, which can realize the stable movement of the workpiece 101 and improve the displacement accuracy of the processing points. At the same time, when replacing the cutting line 8 or repairing the cutting body later, it is only necessary to control the lifting platform 1 to move downward and the base 2 away from the cutting body. At this time, the cutting body is at a lower position to facilitate the operation of the staff.

[0051] Reference Figure 1 - Fig.13 , protrusions 11 are provided on both sides of the base 2, the protrusions 11 are arranged along the transverse direction of the base 2, and a first slide groove 12 is provided on the side walls opposite to the two protrusions 11, and the first slide groove 12 is arranged along the transverse direction of the base 2, and both sides of the base plate 3 extend and are slidably connected in the first slide groove 12;

[0052] Considering the problem of the size of the space between the placement groove 4 and the arc groove 7, a single space can only process workpieces 101 of the same specification and size, and the adaptability is poor. For this reason, the substrate 3 is set to be replaceable, and the substrate 3 has a variety of specifications with different thicknesses. When processing a workpiece 101 with a larger diameter, a substrate 3 with a smaller thickness can be installed, and both sides of the substrate 3 can be slid into the first slide groove 12, which is more convenient to replace;

[0053] At the same time, it is also considered to process some workpieces 101 with different diameters at both ends, such as Figure 7 As shown, two substrates 3 with different thicknesses can be installed in the No. 1 slide groove 12, which can support and lift multiple workpieces 101, ensure the stability of the workpieces 101, and is more flexible to use, and can process workpieces 101 of various specifications.

[0055] The connecting plate 14 is arranged along the transverse direction of the base 2, and the lower horizontal part of the connecting plate 14 is embedded in the No. 2 slide groove 13, the upper horizontal part of the connecting plate 14 is placed on the upper surface of the protrusion 11, and the upper surface of the upper horizontal part of the connecting plate 14 is connected to the two vertical ends of the lower pressure plate 6; the lower horizontal part of the connecting plate 14 is slidably connected in the No. 2 slide groove 13. When processing workpieces 101 of different sizes, the connecting plate 14 can be removed from the No. 2 slide groove 13, and the lower pressure plate 6 can be removed together with the connecting plate 14, and the lower pressure plate 6 can be replaced, and the lower pressure plate 6 that can adapt to the size of the workpiece 101 to be processed, or the lower pressure plate 6 can be removed. Some workpieces 101 are solid, and their own weight can stably sit in the placement groove 4 without the need for the lower pressure plate 6 to press down.

[0056] Reference Figure 1 - Fig.13 A plurality of No. 1 sliding holes 15 are horizontally provided in each No. 1 sliding groove 12, and the No. 1 sliding hole 15 penetrates the outer wall of the protrusion 11, and a No. 1 latch 16 is provided in the No. 1 sliding hole 15, and the No. 1 latch 16 is slidably connected in the No. 1 sliding hole 15 through a return spring; No. 1 fixing holes 17 adapted to the No. 1 latch 16 are provided on both sides of the base plate 3;

[0057] Chamfers are set at both ends of the connecting plate 14. When the connecting plate 14 is slidably installed in the No. 2 slide groove 13, the chamfer first squeezes the outer end of the No. 1 pin 16, and squeezes the No. 1 pin 16 to the No. 1 slide hole 15. At the same time, the inner end of the No. 1 pin 16 protrudes and is embedded in the No. 1 fixing hole 17. At this time, the No. 1 pin 16 fixes the substrate 3 on the base 2, and the substrate 3 can be further fixed on the lifting platform 1 to prevent the substrate 3 from shifting due to its own inertia when moving horizontally on the base 2, which affects the deviation of the processing point on the workpiece 101.

[0058] Reference Figure 1 - Fig.13 The upper surface of the upper horizontal portion of the connecting plate 14 is provided with a plurality of rectangular grooves 18, and the rectangular grooves 18 are L-shaped; the vertical end of each of the lower pressing plates 6 is provided with an L-shaped plug block 19;

[0059] Each lower pressure plate 6 is independently arranged on the connecting plate 14 and can be flexibly replaced according to the size specifications of the workpiece 101; install the lower pressure plate 6, embed the insert block 19 in the rectangular groove 18, and push the lower pressure plate 6 to move toward the inner bottom of the rectangular groove 18, at this time, the insert block 19 can be fixed in the rectangular groove 18 in the vertical direction, remove the lower pressure block 27, and push the lower pressure plate 6 to move in the opposite direction, so that the insert block 19 is horizontally separated from the bottom of the rectangular groove 18, and the lower pressure plate 6 can be taken out at this time.

[0060] Reference Figure 1 - Fig.13 A second sliding hole 20 is formed in the bottom surface of each rectangular groove 18 in the vertical direction, and the second sliding hole 20 penetrates to the lower surface of the upper horizontal portion of the connecting plate 14, and a second latch 21 is provided in the second sliding hole 20, and the second latch 21 is slidably connected in the second sliding hole 20 through a return spring; a plurality of second fixing holes 22 are formed on the upper surface of the protrusion 11;

[0061] A No. 2 latch 21 is set on the connecting plate 14. When the lower pressure plate 6 is installed on the connecting plate 14, the plug block 19 on the lower pressure plate 6 is inserted into the rectangular groove 18, and at the same time, the No. 2 latch 21 is pressed downward, and the lower end of the No. 2 latch 21 is pressed into the No. 2 fixing hole 22. At this time, the installation of the lower pressure plate 6 is completed, and the connecting plate 14 is further fixed on the protrusion 11 through the No. 2 latch 21, which improves the integrity among the bottom plate, the base plate 3 and the lower pressure plate 6, and helps to improve the accuracy of the displacement of the workpiece 101.

[0062] Reference Fig.14 - Fig.15 , each of the lower pressing plates 6 is provided with a plurality of auxiliary components, the auxiliary components including a base block 23 arranged on the upper surface of the lower pressing plate 6, a bolt 24 is spirally connected to the base block 23, the lower end of the bolt 24 penetrates into a guide groove 25 opened on the top surface of the arc groove 7, the groove body of the guide groove 25 is arranged in an "eight" shape, and an extrusion plate 26 is symmetrically arranged in the guide groove 25, the lower end of the extrusion plate 26 extends to the notch position of the guide groove 25, the upper end of the extrusion plate 26 is rotatably connected to a pressing block 27, and the pressing block 27 is rotatably connected to the lower end of the bolt 24;

[0063] The auxiliary components in this embodiment are designed for some lighter workpieces 101 to prevent the workpieces 101 from being displaced during cutting, such as some aluminum pipes, iron pipes with smaller thickness, etc. During online cutting, a dielectric liquid is also used. The dielectric liquid has two main functions: one is to cool the workpiece 101, and the other is to wash away tiny chips and keep the spark gap area clean. At this time, the dielectric liquid may drive the workpiece 101 to move for lighter workpieces 101, especially the short and small parts that have been cut off, which are more likely to flow with the dielectric liquid and come into contact with the cutting line 8, affecting the normal operation of the cutting line 8. For this reason, an auxiliary component is set on the lower pressure plate 6; the bolt 24 is rotated, and the bolt 24 drives the pressure block 27 to press down, and pushes the extrusion plate 26 to move out along the guide groove 25, and finally squeezes on the surface of the workpiece 101. At this time, the extrusion plate 26 firmly squeezes and stabilizes the workpiece 101 to ensure the subsequent cutting stability;

[0064] The lower pressing plate 6 designed in this embodiment also has various specifications, that is, the vertical parts at both ends of the lower pressing plate 6 have different lengths, so that downward pressure can be applied to workpieces 101 of different specifications.

[0065] Reference Figure 1 , Fig.16 and Fig.17 , a liquid supply unit is provided at one end of the lifting platform 1;

[0066] The liquid supply unit includes a bracket 28 fixedly connected to one end of the lifting platform 1, and a plurality of springs are arranged on the bracket 28. A sleeve 29 is fixedly connected to the end of the spring. A liquid supply pipe 30 is inserted into the sleeve 29. A fastening bolt 31 is arranged above the sleeve 29. The fastening bolt 31 is threadedly passed through the sleeve 29 and can be squeezed on the liquid supply pipe 30.

[0067] In this embodiment, the designed liquid supply unit is used to provide medium liquid for the tubular workpiece 101, and the liquid supply unit provides medium liquid for it from the tube body, so that the medium liquid can completely cover the processing point of the pipe fitting and wash away tiny chips at the same time; one end of each liquid supply tube 30 is connected to the external liquid pump through the hose 32, and the liquid pump can pump the medium liquid into the liquid supply tube 30, and the other end of the liquid supply tube 30 is inserted into a port of the pipe fitting, and the other end of the pipe body can be temporarily blocked with a rubber block. When the cutting line 8 cuts the pipe fitting, a bamboo tube is first used outside the pipe fitting to provide medium liquid for the outer surface of the pipe fitting. When the cutting line 8 penetrates the pipe wall of the pipe fitting, the liquid pump is driven, and the medium liquid flows out from the liquid supply tube 30, fills the inside of the pipe fitting, and overflows from the cutting port, and the medium liquid flows along the cutting port, which can completely take away the chips and will not flow at the edge of the cutting port, thereby reducing the impact of the chips on the remaining uncut parts.

[0068] The fastening bolt 31 and the sleeve 29 are provided to adjust the insertion depth of the liquid supply tube 30 into the pipe fitting to prevent the cutting line 8 from squeezing and touching the liquid supply tube 30 and causing the cutting line 8 to be disconnected. The sleeve 29 is connected to the bracket 28 by a spring, so that the liquid supply tube 30 can be smoothly inserted into pipe fittings of different heights. The elasticity of the spring itself can move the liquid supply tube 30 up and down, so that the liquid supply tube 30 is inserted into the pipe fitting.

[0069] Reference Figure 1 , Fig.16 and Fig.17 The end of the liquid supply pipe 30 is fixedly connected with a rubber bladder 33, one side of the rubber bladder 33 is fixedly connected with a cover 34, the liquid supply pipe 30 and the cover 34 are connected through the rubber bladder 33, and a plurality of drainage holes 35 are provided on the rubber cover 34;

[0070] A rubber bladder 33 is arranged at the other end of the liquid supply pipe 30, and a cover body 34 with a plurality of drainage holes 35 is arranged on the rubber bladder 33. When the medium liquid is injected into the liquid supply pipe 30, the hydraulic pressure of the medium liquid causes the rubber bladder 33 to expand and squeeze on the inner wall of the pipe fitting. At the same time, the medium liquid is discharged into the pipe fitting from the drainage holes 35 and finally discharged from the incision on the pipe fitting. The designed rubber bladder 33 is used to block the other end of the pipe fitting. One end of the pipe fitting is temporarily blocked by a rubber block, and the other end of the pipe fitting is blocked by the expandable rubber bladder 33, so that the medium liquid is blocked in the pipe body, and the medium liquid can fully flush and cool the cut.

[0071] Reference Fig. 9 - Fig.11 A locking assembly is provided on the vertical portion of each of the lower pressing plates 6, and the locking assembly includes an insert plate 36 slidably connected to the side wall of the vertical portion of the lower pressing plate 6, and the insert plate 36 can be inserted into the rectangular groove 18; when the lower pressing plate 6 is installed, the insert plate 36 is lifted by fingers, and then the insert block 19 is inserted into the rectangular groove 18. When the insert block 19 is installed in place, the insert plate 36 is released, and the insert plate 36 is squeezed into the gap between the insert block 19 and the rectangular groove 18, filling the gap between the insert block 19 and the rectangular groove 18, thereby improving the stability between the insert block 19 and the rectangular groove 18, and also improving the stability of the lower pressing plate 6.

[0072] Working principle:

[0073] Place the workpiece 101 flat on the substrate 3, then find the lower pressure plate 6 that matches the specifications of the workpiece 101, and install the lower pressure plate 6 on the connecting plate 14 through the plug block 19, and then drive the horizontal screw rod 10 to move the processing point on the workpiece 101 to the bottom of the cutting line 8. If the workpiece 101 to be processed is a pipe fitting, after the processing point on the workpiece 101 moves to the bottom of the cutting line 8, one end of the pipe fitting is sealed with a rubber block, and the other end of the liquid supply pipe 30 is inserted into the pipe fitting, and then the vertical screw rod 9 is driven, the processing point on the workpiece 101 gradually moves upward, and the cutting line 8 also starts to run and cuts the processing point. When the cutting line 8 cuts the pipe fitting, first use a bamboo tube outside the pipe fitting to provide medium liquid for the outer surface of the pipe fitting. When the cutting line 8 penetrates the pipe wall of the pipe fitting, the liquid pump is driven, and the medium liquid flows out from the liquid supply pipe 30. The medium liquid fills the inside of the pipe fitting and overflows from the cutting port.
