Description

Technical Field

[0001] The present application relates to the field of welding and cutting technology, and in particular to a welding and cutting machine for a cutting machine tool with a processing system. Background Art

[0002] Welding and cutting machine tools are professional mechanical equipment with advanced technology and powerful functions. They use a variety of high-tech welding technologies such as efficient gas shielded welding and precise argon arc welding. By generating a stable arc or high-temperature heat source, the metal reaches the melting point and fuses instantly, achieving a firm and reliable connection. At the same time, they use cutting-edge cutting methods such as flame cutting or plasma cutting, with the help of high-energy heat flow or ion beam, to quickly and accurately divide metal materials, meet the strict requirements for metal processing in various complex industrial manufacturing scenarios, and provide indispensable key support for modern industrial production.

[0003] When the welding machine is in use, waste is generated due to welding or cutting. When the waste cools down, it may stick to the welding platform. Therefore, the welding platforms of most existing welding machines are hollow, so that the waste can pass through the welding machine and fall to the bottom, thereby reducing the waste sticking to the welding platform.

[0004] When the existing welding and cutting machines are in use, although the waste will pass through the welding and cutting machine bed and fall to the bottom, the waste may still stick to the bottom of the machine bed after cooling, which not only increases the cleaning workload of the operator, but also the long-term accumulation of waste may cause damage to the welding and cutting machine bed. Summary of the invention

[0005] In order to facilitate the collection of waste materials during welding and cutting and to prevent the waste materials from sticking to the welding and cutting machine tool, the present application provides a welding and cutting machine for a cutting machine tool with a processing system.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0022] By adopting the above scheme, when waste collection is required, the driving motor drives the first threaded rod to rotate, so that the pusher plate moves toward the collection box, and at the same time, the first threaded rod drives the second threaded rod to rotate through the transmission of the first bevel gear and the second bevel gear, thereby driving the lifting frame and the collection box to descend, so that the pusher plate pushes the waste into the collection box, and then the driving motor moves in the opposite direction to return the pusher plate to its original position, and the lifting frame moves upward, thereby driving the collection box to move above the machine tool body, so that the operator can clean the waste in the collection box more conveniently.

Both ends of the moving gantry 2 are respectively slidably connected to the two longitudinal slide rails, and a travel cylinder 21 is slidably connected to the gantry 2, and the travel cylinder 21 is connected to a welding gun 3. A waste trough 11 is opened above the machine body 1, and a support frame 4 for supporting welding materials is arranged on the waste trough 11. The support frame 4 is composed of multiple cross bars and vertical bars, and gaps are left between the multiple cross bars to allow waste to pass through, and gaps are left between the multiple vertical bars to allow waste to pass through. Cooling liquid for cooling the waste is arranged in the waste trough 11. When cutting the welding material, the gantry 2 slides along the longitudinal slide rail, and the travel cylinder 21 slides along the gantry 2, thereby driving the welding gun 3 to move above the machine tool body 1, and then the welding gun 3 cuts or welds the welding material, and the waste generated by the welding falls and passes through the gap between the support frames 4, so that the waste falls into the waste trough 11, and the waste is cooled by the coolant in the waste trough 11, so that the waste is cooled before falling to the bottom of the trough, so that the waste is cooled and falls into the bottom of the waste trough 11.

[0041] Reference Figure 2 and Figure 3The machine tool body 1 is connected with a circulation structure 5 for filtering and recycling the coolant. The circulation structure 5 includes a water pump 51, a water inlet pipe 52 and a water outlet pipe 53. The water inlet pipe 52 connects the water pump 51 with the bottom of the waste tank 11, and the water outlet pipe 53 connects the water pump 51 with the upper position of the waste tank 11. A filter screen for blocking the entry of waste is arranged at one end of the water inlet pipe 52 connected to the bottom of the waste tank 11. A water distribution pipe 531 is arranged around the waste tank 11. A plurality of water distribution holes are opened on the surface of the water distribution pipe 531, and the water distribution pipe 531 is connected with the water outlet pipe 53. The coolant enters the water pump 51 through the water inlet pipe 52, and the filter screen blocks the waste. Then the water pump 51 drives the coolant to spray out at the water outlet pipe 53, thereby accelerating the flow rate of the coolant, thereby accelerating the cooling of the coolant, and making the cooling effect of the coolant better. The coolant enters the water distribution pipe 531, flows along the water distribution pipe 531 to the upper and lower parts of the waste tank 11, and flows out along the water distribution hole, so that the filtered coolant can be more evenly dispersed above the waste tank 11, while also reducing the kinetic energy of the coolant and reducing the fluctuation of the coolant water surface.

[0042] Reference Figure 2 The highest liquid level of the coolant is lower than the upper surface of the support frame 4, so as to avoid the coolant level being too high and causing the waste to stick to the support frame 4 after cooling.

A mesh for filtering water is arranged on the surface of the collecting box 61. The collecting box 61 is arranged on one side of the waste trough 11. Rod grooves are provided on the two side surfaces of the waste trough 11 adjacent to the collecting box 61, and the lower surface of the rod groove is inclined, so that the waste falling into the rod groove falls along the inclined surface to the bottom of the waste trough 11, and a first threaded rod 621 and a first guide rod 623 are respectively provided in the two rod grooves. The first threaded rod 621 is rotatably connected in the rod groove, and a driving motor 622 is fixedly connected to one end of the first threaded rod 621. Threaded holes and round holes are respectively provided at both ends of the pushing plate 62, and the first threaded rod 621 is threadedly connected to the pushing plate 62 through the threaded hole, and the first guide rod 623 is slidably connected to the pushing plate 62 through the round hole. When waste collection is required, the driving motor 622 drives the first threaded rod 621 to rotate, thereby driving the pushing plate 62 to move toward the collection box 61, so that the pushing plate 62 pushes the fallen waste into the collection box 61, and the guide rod limits the pushing plate 62, thereby collecting the waste in the waste trough 11 into the collection box 61, making it convenient for the operator to clean up the waste.

[0044] Reference Figure 5 and Figure 6A lifting slot 13 is provided in the machine tool body 1, and a through hole 12 is provided on one side of the waste slot 11. The through hole 12 connects the lifting slot 13 with the waste slot 11. A lifting frame 7 is slidably connected in the lifting slot 13. The lifting frame 7 is connected to the collecting box 61, and the collecting box 61 and the lifting frame 7 are detachable. In addition to the side of the collecting box 61 close to the through hole 12, the other three sides of the collecting box 61 are higher than the side of the collecting box 61 close to the through hole 12, so as to prevent the waste from falling into the collecting box 61. A second guide rod 72 and a second threaded rod 71 are separately provided. The second threaded rod 71 is rotatably connected in the lifting groove 13. The second threaded rod 71 is threadedly connected to the lifting frame 7. The second guide rod 72 is slidably connected to the lifting frame 7. One end of the first threaded rod 621 penetrates into the lifting groove 13, and one end of the first threaded rod 621 located in the lifting groove 13 is fixedly connected with the first bevel gear 624. One end of the second threaded rod 71 is provided with a second bevel gear 711, and the first bevel gear 624 is meshed with the second bevel gear 711. When waste collection is required, the driving motor 622 drives the first threaded rod 621 to rotate, so that the push plate 62 moves toward the collection box 61. At the same time, the first threaded rod 621 drives the second threaded rod 71 to rotate through the transmission of the first bevel gear 624 and the second bevel gear 711, thereby driving the lifting frame 7 and the collection box 61 to descend, so that the push plate 62 pushes the waste into the collection box 61. Then, the driving motor 622 moves in the opposite direction, so that the push plate 62 returns to its original position, and the lifting frame 7 moves upward, thereby driving the collection box 61 to move above the machine tool body 1, so that the operator can more conveniently clean the waste in the collection box 61.

[0045] Reference Figure 7A spring groove 14 is provided on the side surface of the through hole 12, and a baffle 8 is slidably connected in the spring groove 14, and a spring 81 is arranged in the spring groove 14, and both ends of the spring 81 are respectively connected to the spring groove 14 and the baffle 8. When the spring 81 is at its original length, the baffle 8 blocks the through hole 12, and a transmission hole 15 is provided on one side surface of the spring groove 14, and the transmission hole 15 connects the spring groove 14 with the lifting groove 13, and a transmission gear 83 is rotatably connected in the transmission hole 15, and a first tooth groove 82 is provided on the baffle 8 opposite to the transmission hole 15, and the transmission gear 83 is meshed with the first tooth groove 82, and a second tooth groove 73 is provided on the surface of the lifting frame 7, and the second tooth groove 73 is meshed with the transmission gear 83. When the lifting frame 7 descends to the lowest position, the baffle 8 opens to connect the waste trough 11 with the lifting groove 13. When there is no need to clean the waste, the baffle 8 blocks the through hole 12 to prevent the waste from entering the lifting groove 13 during welding and cutting. When the waste needs to be cleaned, the driving motor 622 drives the first threaded rod 621 and the second threaded rod 71 to rotate, so that the lifting frame 7 moves downward. When the lifting frame 7 moves to the lower position, the transmission gear 83 engages with the second tooth groove 73, so that the lifting frame 7 drives the transmission gear 83 to rotate, so that the transmission gear 83 drives the baffle 8 to move upward, thereby driving the baffle 8 to open, so that the waste can enter the lifting groove and fall into the collection box 61.

[0046] The specific implementation principle of the present application is: when welding and cutting are required, the gantry 2 moves along the longitudinal slide rail, and the travel cylinder 21 moves along the gantry 2, thereby driving the welding and cutting gun 3 to move above the machine tool body 1, so that the welding and cutting gun 3 performs welding and cutting on the welding and cutting materials, and the waste passes through the gap between the support frames 4 and falls into the coolant in the waste trough 11, so that the waste is cooled, and then the waste falls to the bottom of the waste trough 11. Since the coolant accelerates the cooling of the waste, the waste is cooled before falling to the bottom of the waste trough 11, thereby preventing the waste from sticking to the machine tool body 1; the circulation structure 5 allows the coolant to flow, accelerates the cooling of the coolant, and makes the cooling effect of the coolant better. When it is necessary to clean the waste, the driving motor 622 rotates, and the driving motor 622 drives the first threaded rod 621 to rotate, thereby driving the pushing plate 62 to move towards the collecting box 61. At the same time, the first threaded rod 621 drives the second threaded rod 71 to rotate through the rotation of the first bevel gear 624 and the second bevel gear 711, so that the lifting frame 7 and the collecting box 61 descend. When the collecting box 61 descends to near the bottom of the lifting groove 13, the transmission gear 83 engages with the second tooth groove 73, so that the lifting frame 7 drives the transmission gear 83 to rotate, so that the transmission gear 83 drives the baffle 8 to move upward, so that the through hole 12 is opened, and then the pushing plate 62 pushes the fallen waste into the collecting box 61, and then the driving motor 622 is flipped to make the pushing plate 62 return to its original position, and the lifting frame 7 moves upward, so that the waste box reaches the top of the machine tool body 1, which is convenient for the operator to clean the welding slag. At the same time, the lifting frame 7 drives the baffle 8 to close to prevent the waste from falling under the collecting box 61.
