Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a cutting and welding machine. Background Technology

[0002] During steel strip production, the tail end of the preceding steel strip needs to be welded to the head end of the following steel strip to form a single unit. Before welding, a section of scrap material needs to be removed from the tail end of the preceding steel strip and / or the head end of the following steel strip to facilitate better alignment of the two sections. In another application scenario, when the aspect ratio of the sheet material needs to be changed, the square sheet material is first cut in half along one of its parallel sides, and then butt-welded along the other side. In both of these applications, the sheet material must first be cut, followed by alignment and welding.

[0003] One related technical solution provides a shearing butt welding machine, which uses a cutter and hydraulic components to shear the plate at the bottom of the butt welding machine, and then moves the plate to the top of the equipment for alignment welding.

[0004] The above technical solution has two drawbacks. First, because hydraulic shearing requires rigid compression of the sheet metal, the cut end face of the sheet metal becomes too rough, making it difficult to control the quality after welding. Second, since the shearing and welding of the sheet metal occur at different heights, the sheet metal needs to be manually transferred to workstations at different heights, which consumes more time. Utility Model Content

[0005] This invention provides a cutting and welding machine that can solve at least one of the above-mentioned technical problems.

[0006] To address the aforementioned technical problems, one or more embodiments of this utility model provide a cutting and welding machine, including a frame having a first direction and a second direction that are horizontal and perpendicular to each other. A worktable is mounted on the frame, and two clamping members are positioned above the worktable. These clamping members are capable of rising and falling to clamp the sheet metal to be processed on the worktable. A welding torch assembly is also positioned above the worktable, capable of moving along the first direction to weld the two butted sheet metal pieces.

[0007] A saw blade assembly is located below the workbench, comprising a vertical saw blade parallel to a first direction. The saw blade is rotatable about its own axis. The workbench has a through-slot extending vertically along the first direction. The upper end of the saw blade passes through the through-slot and is above the upper surface of the workbench. The saw blade assembly is translatable along the first direction to cut the sheet metal pressed between the clamping element and the workbench.

[0008] The beneficial effects of one or more of the above technical solutions are as follows:

[0009] Compared to the traditional method of hydraulic shearing, this solution utilizes the rotation of the saw blade to cut the sheet metal, which facilitates the improvement of the flatness of the cut end face of the sheet metal and is beneficial to improving the quality of the weld after subsequent welding of the sheet metal.

[0010] In this design, two clamping components and a welding gun assembly capable of translational movement along a first direction are located above the worktable. A saw blade assembly is located below the worktable. A vertical through-slit is formed on the worktable, with the upper end of the saw blade passing through and extending above the upper surface of the worktable. This allows the worktable to simultaneously cut the sheet metal and weld the two cut sheets together on its upper surface. Compared to existing technologies that place sheet metal cutting and welding at different heights, this design saves space in the welding machine, reduces the steps of moving the sheet metal up and down, and decreases the welding time required after cutting the sheet metal.

[0011] In addition, the clamping components of this solution can not only achieve clamping and positioning when cutting the plate, but also achieve clamping and positioning when welding the two plates together after cutting. That is, this solution can improve the utilization rate of the two clamping components and eliminate the need for additional clamping fixtures when sawing the plate, thus saving on structure.

Detailed Implementation

[0019] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0020] like Figures 1-6 As shown, one or more embodiments of this utility model provide a cutting and welding machine, including a frame having a first direction and a second direction that are horizontal and perpendicular to each other. A worktable 16 is provided on the frame, and a plurality of clamping members 12 are provided above the worktable 16. The clamping members 12 can be raised and lowered respectively to clamp the plates to be processed on the worktable 16. A welding gun assembly is also provided above the worktable 16, which can move along the first direction to weld the two plates after they are butt-jointed.

[0021] A saw blade assembly is located below the workbench 16, comprising a vertical saw blade 17 parallel to a first direction. The saw blade 17 is rotatable about its own axis. The workbench 16 has a through-slit 161 extending vertically through itself in the first direction. The upper end of the saw blade 17 passes through the through-slit 161 and is above the upper surface of the workbench 16. The saw blade assembly is capable of translational movement in the first direction to cut the sheet metal pressed between the clamping member 12 and the workbench 16.

[0022] Specifically, the frame includes two side plates perpendicular to the second direction, with the worktable 16, welding torch assembly, and sawing assembly all located between the two side plates. The frame also includes two end plates 23 perpendicular to the first direction, with the two side plates sealing off their ends along the first direction. In other words, in this embodiment, the side plates and end plates 23 of the frame form a roughly square working cavity to separate the cutting and welding components from the outside environment.

[0023] Specifically, an observation port 24 is provided at the end plate 23 on the front side of the frame. A filter is fixed to the observation port 24 by screws. The filter is used to observe and adjust the movement trajectory of the welding torch 8.

[0024] It should be noted that the horizontal setting of the first and second directions mentioned above should be understood as approximate horizontal. That is to say, the first and second directions can deviate from the absolute horizontal plane by about 10 degrees.

[0025] Specifically, the worktable 16 here is a long plate-shaped structure, and the length of the worktable 16 along the first direction is greater than its width along the second direction.

[0026] In this embodiment, the clamping member 12 is a pressure plate, one of which is located directly above the through-slit 161. The pressure plate located directly above the through-slit 161 has a receiving groove 15, which can accommodate the portion of the saw blade 17 that is higher than the worktable 16.

[0027] As a specific structural form, the cross-section of the receiving groove 15 perpendicular to the first direction is square. In other embodiments, the cross-section of the receiving groove 15 perpendicular to the first direction can be semi-circular or other shapes, which can be set by those skilled in the art.

[0028] In this embodiment, there are two clamping members 12, which are arranged opposite each other along the second direction. There is a gap 19 between the two clamping members 12 extending along the first direction to expose the seam of the two plates to the welding gun assembly.

[0029] Preferably, the two clamping members 12 are arranged symmetrically about the center of the frame along the second direction, so that the frame worktable 16 can evenly bear the force of the clamping members 12 clamping the plate. The gap 19 here is a long strip, and the welding gun 8 in the above-mentioned welding gun assembly can pass through the gap 19 to weld the joint between the two plates.

[0030] See Figure 2 and Figure 4 In this embodiment, the two clamping members 12 are respectively disposed on the inner side of the two side plates of the frame, and the side wall of the clamping member 12 is fitted with the inner wall of the side plate. At this time, the inner wall surface of the side plate can guide the clamping member 12 when it moves vertically, thereby reducing the probability of the clamping member 12 being tilted due to uneven force when it moves up and down.

[0031] More specifically, a clamping space 11 is formed between the lower surface of the clamping member 12 and the upper surface of the worktable 16. After the plate to be sawed or welded is placed in the clamping space 11, the clamping member 12 moves down to clamp the plate.

[0032] For ease of manufacturing, the aforementioned receiving groove 15 is provided below both pressure plates, thus requiring only one type of pressure plate to be produced. More specifically, the receiving groove 15 extends through both end faces of the entire pressure plate along the first direction, thereby ensuring that the pressure plate does not obstruct the saw blade 17 from entering or leaving the pressure plate along the first direction, ultimately ensuring that the pressure plate does not hinder the saw blade 17 from sawing the plate.

[0033] In this embodiment, the upper surface of the workbench 16 is provided with a copper electrode 162 extending along the first direction, and the copper electrode 162 is located directly below the gap 19.

[0034] Specifically, when using copper electrode 162, the copper electrode 162 can assist the welding torch 8 in welding the plate. The copper electrode here has the characteristics of high temperature resistance and rapid heat dissipation, which facilitates long-term assistance to the welding torch 8 in welding the plate.

[0035] In this embodiment, each of the two side plates has a feed inlet 5 that extends through itself in the second direction. The lower end of the feed inlet 5 is not higher than the upper end of the worktable 16, and the upper end of the feed inlet 5 is higher than the upper end of the worktable 16.

[0036] Specifically, the feed inlet 5 here is a square opening that runs through the entire side panel structure. The length of the feed inlet 5 along the first direction is not less than the size of the sheet material to be cut, so that the sheet material can be inserted into the clamping space 11 inside the frame through the feed inlet 5.

[0037] As can be seen, when the feed inlets 5 are set on both sides of the frame, when sawing the plates: a single plate can be inserted from either feed inlet 5 on both sides, and then pressed by the clamping member 12 above the saw blade 17. When welding plates, two plates are inserted into the clamping space 11 in the frame from the feed inlets 5 on both sides respectively. The joint of the two plates is located directly below the gap 19 of the two clamping members 12, and then the two plates are pressed together.

[0038] In this embodiment, the side plate includes a separate upper side plate 6 and a lower side plate 4, and the feed port 5 is formed at the interface between the upper side plate 6 and the lower side plate 4.

[0039] See Figure 1 The upper side plate 6 has a lower protrusion, and the lower side plate 4 has an upper protrusion. The upper and lower protrusions are arranged alternately along a first direction, and the vertical height of the upper protrusion is lower than that of the lower protrusion. That is, when the upper side plate 6 and the lower side plate 4 are vertically joined, the lower protrusion is in contact with the bottom surface of the upper side plate 6, and a gap 19 is formed between the bottom surface of the upper protrusion and the end face of the lower side plate 4 to form the feed inlet 5.

[0040] The upper side plate 6 and the lower side plate 4 are fixed by welding or riveting, which can be set by those skilled in the art.

[0041] Specifically, the lower side plate 4 is provided with a replacement port 401, which facilitates the replacement of the saw blade 17.

[0042] In this embodiment, the welding torch assembly and the saw blade assembly are driven by different linear drive components to translate along the first direction. The linear drive components are, but are not limited to, electric push rods, lead screw and nut assemblies or linear motors.

[0043] See Figure 5 The welding torch assembly is driven to translate along the first direction via a lead screw and nut assembly. Specifically, two brackets 13 are installed on the inner wall of one of the upper side plates 6, and the two ends of the lead screw 20 are rotatably mounted on the two brackets 13, extending along the first direction. A nut seat 21 is installed on the lead screw 20, and the nut seat 21 is connected to the welding torch 8 via a connector (not shown in the figure). One end of the lead screw 20 is connected to the output shaft of a rotary motor. During the rotation of the lead screw 20, the nut seat 21 drives the welding torch 8 to translate along the first direction.

[0044] Specifically, a lightweight slide rail 26 is provided on the side wall of one of the upper side plates. The slide rail 26 is connected to the slide groove on the nut seat, thereby guiding the welding torch 8 when the nut seat 21 drives it to move horizontally.

[0045] Specifically, the saw blade assembly includes a saw blade 17, which is coaxially fixed to the output shaft of the drive motor 10. The shaft of the drive motor 10 is horizontal and extends along a second direction. A cutting slide 9 is provided in the lower housing. The housing of the drive motor 10 is slidably connected to the cutting slide 9 via a guide (not shown in the figure) to guide the saw blade assembly when it translates along the first direction. The linear drive component required for the saw blade assembly is not shown in the figure; it can be designed by those skilled in the art.

[0046] In this embodiment, both clamping members 12 are pressure plates, and the upper ends of the adjacent sides of the two pressure plates are chamfered.

[0047] Specifically, by using a chamfer, a funnel-shaped space can be formed on the adjacent side of the two pressure plates. The gap 19 between the two pressure plates gradually decreases from top to bottom, making it easier to accommodate part of the structure at the lower end of the welding torch 8 using the larger gap 19 at the upper end.

[0048] In this embodiment, a lower housing 3 is also included, with a frame fixed to the upper end of the lower housing 3. The lower housing 3 houses a welding machine 25 with welding components and an electrical control box. Above the welding machine 25 is a receiving box 22 with an upper opening 27, located below the saw blade to receive waste material falling from the saw blade. An argon cylinder storage box 1 is also installed on the lower part of the outer side of the lower housing.

[0049] Specifically, the size of the receiving box 22 will be adjusted according to the model of the cutting and welding machine.

[0050] Specifically, an opening 27 is provided on the top plate of the lower box. The opening 27 is located between the receiving box 22 and the saw blade. Waste material generated by sawing at the saw blade falls into the receiving box 22 of the lower box through the opening 27.

[0051] In this embodiment, the clamping member 12 is driven by a lifting assembly, which includes, but is not limited to, a cylinder, an electric push rod, or a hydraulic cylinder. See also Figure 4 When the lifting assembly uses cylinder 14, the cylinder body of cylinder 14 is fixed to the inner wall of the upper side plate 6 of the frame, and the piston rod 18 of cylinder 14 extends vertically downward and is fixed to the upper end of the clamping member 12.

[0052] When the lifting assembly above the clamping member 12 is a cylinder 14, a gas station (not shown in the figure) for the matching cylinder 14 is also installed in the lower housing 3. In some other embodiments, when the lifting assembly above the clamping member 12 is a hydraulic cylinder, a hydraulic station for the matching hydraulic cylinder is also installed in the lower housing.

[0053] Additionally, in this embodiment, a lighting assembly 7 is provided above the frame to facilitate workers' observation of whether the sheet metal is accurately positioned within the pressing space 11. Casters 2 are also provided at the bottom of the lower housing 3, allowing the entire welding machine 25 to move between different workstations.

[0054] Specifically, in this embodiment, a strong magnet is provided on the base of the lower part of the lighting component 7. The strong magnet of the base can attract the entire lighting component 7 to different positions on the frame so as to move the lighting component 7 as needed.

[0055] Working principle: When using this device to cut the board, the saw blade assembly moves along the first direction to avoid the board to be cut. The board to be cut is inserted into the clamping space 11 from the feed port 5 near the saw blade 17, and the clamping member 12 moves down to clamp the board. Finally, the entire sawing assembly moves towards the board along the first direction, the upper end of the saw blade 17 is in the receiving groove 15, and the saw blade 17 rotates to complete the cutting of the board.

[0056] When welding is required, the clamping member 12 is lifted, placing the two plates to be welded below the two clamping members 12 respectively, with the end faces of the two plates touching and the joint directly below the gap. Then the welding torch assembly moves along the first direction and welds the two plates into a single unit.

[0057] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0058] Any aspects of this utility model not described in detail are known to those skilled in the art.
