Description

Technical Field

[0001] This invention relates to the field of industrial electromechanical manufacturing technology, and in particular to an industrial electromechanical manufacturing cutting and welding apparatus and method. Background Technology

[0002] In the heart of industrial electromechanical manufacturing, from the skeleton of steel structures, the veins of rail transit, the tendons of ships to the joints of engineering machinery, every cutting and fusion of pipes and rods is a core link that determines the lifespan and reliability of the entire machine.

[0003] To address the problem of positioning errors amplified step-by-step due to the traditional production line process of cutting before welding and multiple clamping operations, which ultimately weakens the geometric accuracy of the weld, existing technologies have gradually developed integrated cutting and welding devices. By integrating cutting, welding, and grinding mechanisms into a single device, after clamping the workpiece, steps such as workpiece rotation cutting, excess material removal, workpiece grinding, and weld welding are performed sequentially. This reduces the number of clamping operations, thereby improving weld accuracy and work progress.

[0004] While the aforementioned integrated cutting and welding equipment has become increasingly widely used due to its advantages such as high operating speed and high weld precision, this integrated equipment creates a heat-affected zone at the edge of the workpiece cut after cutting and grinding. If the workpiece is directly welded without cooling, the coarse grains and residual stress left by the high temperature will induce cracks, porosity, and structural deterioration under the reheating of the electric arc, seriously affecting the weld quality. Currently, the common cooling methods are water cooling and air cooling. Water cooling can cause cooling hardening of high-carbon steel and stainless steel materials, and the active hydrogen released by the decomposition of water vapor is easily absorbed by the weld pool, forming needle-like pores. Air cooling is slow and generates dust, making it unsuitable for thick-walled pipes. It is evident that the above two cooling methods not only place high demands on the waterproofing and sealing of the original mechanisms of the equipment, but also limit the equipment's operation on materials such as high-strength steel, stainless steel, or thick-walled pipes, reducing the equipment's adaptability to materials. Summary of the Invention

The two sliders and the two abutment blocks are respectively provided with mutually cooperating inclined surfaces, and the two abutment blocks are respectively located below the two top rods.

[0008] In at least one embodiment of the present invention, a support platform is provided at the middle position of the lead screw, a lifting platform is provided on the support platform, the rotary drive member is provided on the lifting platform, the lifting member includes two top blocks fitted on both ends of the support platform on the lead screw and two first hinge rods, the two ends of each first hinge rod are respectively connected to the top block and the lifting platform, and the gear mechanism is provided at the middle position of the rotating shaft of the rotary drive member.

[0009] In at least one embodiment of the present invention, two fixed frames are horizontally slidably connected to the worktable, each top rod is hinged with a second hinge rod that is hinged to the lifting platform, the gear mechanism includes two first gears and two second gears, the bottom end of the top rod is provided with a roller, and the grinding component includes: The mounting block is slidably connected to the worktable in the longitudinal direction; the top and bottom of the mounting block are respectively provided with a first rotating shaft and a second rotating shaft, the first rotating shaft and the second rotating shaft are connected by a sprocket mechanism, and the second rotating shaft is provided with two first gears; Both mounting discs are rotatably connected to the first rotating shaft, and a grinding disc is connected to the opposite side of each of the two mounting discs by a spring; Both second gears are mounted on the shaft of the rotary drive component, and the two second gears are located below the two first gears respectively.

[0010] In at least one embodiment of the present invention, a spring rod is longitudinally provided at the top of the inner cavity of the fixed frame, and an inverted U-shaped frame is connected to the movable rod of the spring rod. The two first abutting posts are horizontally rotatably connected in the inverted U-shaped frame, and each of the first abutting posts and the second abutting post is provided with a rubber friction layer.

[0011] In at least one embodiment of the present invention, a plurality of mounting grooves are provided on the inner wall of the heat-conducting block, and a rubber friction strip is embedded in each mounting groove.

[0012] In at least one embodiment of the present invention, the bottom of the workbench is connected to a carrier plate via a support column, the abutting member is disposed on the carrier plate, a guide rod is longitudinally disposed at the bottom of the workbench, and the top of the abutting block is provided with a guide hole with an open top, the guide rod extending into the guide hole.

[0013] In at least one embodiment of the present invention, the position adjustment part includes a lifting part and a horizontal moving part disposed on the lifting part, and the cutting mechanism and the welding mechanism are mounted on the horizontal moving part.

[0014] This invention also proposes an industrial electromechanical manufacturing cutting and welding method, comprising the following steps: When it is necessary to cut the workpiece, the entire workpiece is passed through the fixed frame; then two sets of clamping devices are activated to clamp and fix the workpiece. During the process of the clamping devices clamping and fixing the workpiece from bottom to top, the cooling chain is sleeved on the workpiece. The cutting mechanism is then adjusted by the position adjustment unit to cut the workpiece. At the same time, the cooling medium flows through the cooling channel to remove the residual heat on the workpiece. Simultaneously, the rotary drive is activated so that the rotating shaft of the rotary drive drives the workpiece to rotate through the rotating wheel and the cooling chain, thereby completing the cutting of the entire workpiece. When welding is required, the part of the workpiece to be removed is released by the clamping device, and then the part to be welded is clamped and fixed. Then, the lifting device drives the grinding device to rise to grind the contact surface of the workpiece and form a welding bevel. In the same way as above, the workpiece is rotated by the rotation drive device. After grinding is completed, the lifting device drives the grinding device to retract. Subsequently, during the welding process, the position of the welding mechanism is adjusted by the position adjustment unit, enabling it to complete the welding of the workpiece.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The industrial electromechanical manufacturing cutting and welding device proposed in this invention, during cutting and welding operations, involves passing the workpiece through a mounting frame so that the cutting part of the workpiece is positioned in the center of the worktable. The workpiece is then clamped and fixed from bottom to top by clamping members. During the upward movement and clamping of the workpiece, it lifts the cooling chain hanging on the support rod, ensuring that the heat-conducting blocks fully adhere to the workpiece. Subsequently, during the cutting and welding process between the two cooling chains using the cutting and welding mechanisms, a cooling medium source continuously supplies cooling medium to the cooling channels of each heat-conducting block, rapidly removing heat from the heat-affected zone. Compared to traditional water cooling and air cooling methods, this method avoids workpiece hardening, introduces active hydrogen and dust, effectively suppresses the hardening tendency and residual stress of high-strength steel and heat-resistant alloys, significantly reduces weld cracks and porosity defects, and simultaneously improves post-weld geometric accuracy and surface quality, ensuring the device's adaptability to various materials.

[0016] Simultaneously, during the cutting and welding process of the workpiece, a rotating wheel mounted on the rotary drive component drives the cooling chain to rotate, which in turn causes the workpiece to rotate. This ensures that different cutting and welding areas of the workpiece correspond to independent heat-conducting blocks, guaranteeing the cooling quality of the workpiece while actively rotating it for cutting and welding operations. The use of this cooling chain not only eliminates the need for special waterproofing and sealing requirements on the various mechanisms of existing integrated devices, but also serves as the power component driving the workpiece rotation. This further reduces the structural complexity of the original device, making it suitable for integration into existing integrated cutting and welding devices. Furthermore, the use of a bottom-up clamping mechanism allows the cooling chain to be easily lifted by the workpiece during assembly, minimizing additional steps and adapting to industrialized production operations.

[0022] Combination Figures 1 to 7As shown, an industrial electromechanical manufacturing cutting and welding device includes a worktable 1 with a support frame 11. The support frame 11 is inverted U-shaped and has a position adjustment part 12. A cutting mechanism 13 and a welding mechanism 14 are mounted on the position adjustment part 12. The position adjustment part 12 is used to drive the cutting mechanism 13 and the welding mechanism 14 to move horizontally or vertically, so that the cutting mechanism 13 and the welding mechanism 14 can accurately reach the working area of ​​the workpiece 3. The device also includes: Two sets of fixing parts 2 are arranged opposite each other on both sides of the support frame 11 on the workbench 1. Each fixing part 2 includes a fixing frame 21 arranged on the workbench 1 and a clamping member 22 arranged in the fixing frame 21. The fixing frame 21 has two through ends. When fixing the workpiece 3, the workpiece 3 passes through the fixing frame 21. The top of the inner wall of the fixing frame 21 is horizontally rotatably connected to two first abutting posts. The clamping head 221 of the clamping member 22 is horizontally rotatably connected to two second abutting posts. The clamping member 22 is used to clamp the workpiece 3 from bottom to top. Two horizontal support rods 211 are arranged on the opposite side of the fixing frame 21.

[0023] Two cooling chains 4 are respectively connected to two support rods 211 on two fixed frames 21. Each cooling chain 4 includes multiple heat-conducting blocks 41 that are hinged to each other. The multiple heat-conducting blocks 41 are provided with interconnected coolant channels. The cooling channels on each heat-conducting block 41 are interconnected through flexible pipes. The coolant channels are connected to a cooling medium source. In the specific implementation process, the two cooling chains 4 are kept as close as possible to the cutting and welding position of the workpiece 3, as long as it does not affect the cutting and welding operation. The specific cooling medium is water. The cooling medium source includes a cooling water bath and a water supply pump to continuously supply cooling medium into the cooling channels. The cooling medium source is also equipped with a controller to control the cooling temperature of the cooling water bath and the water supply flow rate of the water supply pump, so that the cooling effect of the entire cooling chain 4 is controllable and adjustable. The specific cooling water bath is set on the lifting platform 63 and rises and falls together with the lifting platform 63.

[0024] The grinding section 5 includes a grinding component 51 located at the bottom center of the workbench 1 and a lifting component 52 connected to the grinding component 51. The lifting component 52 is used to drive the grinding component 51 to move up and down. The grinding section 5 is used to grind the contact surface of the workpiece 3 and form a welding bevel.

[0025] The rotary drive unit 6 is located below the workbench 1. The rotary drive unit 6 is a motor. Its shaft is equipped with a rotating wheel 61 that meshes with two cooling chains 4 and a gear mechanism 62 that connects to the grinding part 5. Specifically, the rotating wheel 61 can be made of rubber and drives the cooling chain 4 to rotate by friction. The rotary drive unit 6 is used to drive the cooling chain 4 to rotate through the rotating wheel 61, so that the cooling chain 4 drives the workpiece 3 to rotate at the same time, so as to cooperate with the cutting mechanism 13 and the welding mechanism 14 to perform operations.

[0026] As an alternative embodiment, the clamping member 22 includes a clamping head 221, a top rod 222 disposed at the bottom of the clamping head 221 and passing through the fixed frame 21 and the worktable 1, and an abutment member 7 disposed below the worktable 1. The abutment member 7 includes a lead screw 71 with bidirectional threads at both ends, a driving member 72 connected to the lead screw 71, sliders 73 threaded to both ends of the lead screw 71, and abutment blocks 74 disposed above the two sliders 73. The two sliders 73 and the two abutment blocks 74 are respectively provided with mutually cooperating inclined surfaces, and the two abutment blocks 74 are respectively located below the two top rods 222; the driving member 72 drives the lead screw 71 The rotation causes the two sliders 73, which are threaded onto the lead screw 71, to move toward opposite sides. Due to the inclined plane, the two sliders 73 push the abutment block 74 upward, which in turn causes the abutment block 74 to drive the clamping head upward via the push rod. The second abutment post on the clamping head cooperates with the first abutment post to clamp the workpiece 3. During the upward movement and clamping of the workpiece 3, the workpiece 3 gradually lifts the cooling chain 4, so that the cooling chain 4 is gradually hung on the workpiece 3. The assembly and use of the cooling chain 4 can be completed by lifting the workpiece, without adding any additional work steps, which is suitable for industrialized production operations.

[0027] As an alternative embodiment, a support platform 711 is provided at the middle position of the lead screw 71. The support platform 711 is a rectangular platform, and a lifting platform 63 is provided on the support platform 711. The rotary drive 6 is set on the lifting platform 63. The lifting component 52 includes two top blocks 521 fitted on the two ends of the support platform 711 on the lead screw 71 and two first hinge rods 522. The two ends of each first hinge rod 522 are respectively connected to the top block 222 and the lifting platform 63. The gear mechanism 62 is located at the middle position of the rotating shaft of the rotary drive 6. The lifting platform 711 is subjected to the action of the two sliders 73, and the two first hinge rods 522 realize the up and down lifting. During the operation of the device, only the forward and reverse rotation of the drive component 72 needs to be controlled to achieve multi-step coordinated control, and the operation steps of the device are simpler.

[0028] As an alternative embodiment, two fixed frames 21 are horizontally slidably connected to the worktable 1. Each top rod 222 is hinged with a second hinge rod 23 that is hinged to the lifting platform 63. The gear mechanism 62 includes two first gears 621 and two second gears 622. Rollers are provided at the bottom ends of the top rods 222. The grinding component 51 includes: a mounting block 511 and two mounting discs 514. The mounting block 511 is longitudinally slidably connected to the worktable 1. The top and bottom of the mounting block 511 are respectively provided with a first rotating shaft 512 and a second rotating shaft 513. The first rotating shaft 512 and the second rotating shaft 513 are connected by a sprocket mechanism. Connected to each other, the second rotating shaft 513 is provided with two first gears 621; the two mounting disks 514 are rotatably connected to the first rotating shaft 512, and the opposite sides of the two mounting disks 514 are connected to the grinding disks 515 by springs; the two second gears 622 are both set on the rotating shaft of the rotating drive 6, and the two second gears 622 are respectively located below the two first gears 621; specifically, the diameter of the second gears 622 is larger than that of the first gears 621, so that when the workpiece 3 is slowly rotated by the cooling chain 4, the grinding disks 515 can be driven at a larger speed to grind the bevel in the welding area of ​​the workpiece.

[0029] As an alternative embodiment, a spring rod is longitudinally provided at the top of the inner cavity of the fixed frame 21. An inverted U-shaped frame is connected to the movable rod of the spring rod. Two first abutment posts are horizontally rotatably connected inside the inverted U-shaped frame. The spring rod allows the first abutment posts to make appropriate clearance during the clamping process of the workpiece 3, thereby enabling the entire device to adapt to clamping operations of workpieces 3 of various diameters. Each of the first and second abutment posts is provided with a rubber friction layer. The rubber friction layer can fully restrict the horizontal axial movement of the workpiece 3 while ensuring stable clamping of the workpiece 3 and not restricting the rotation of the workpiece 3.

[0030] As an alternative embodiment, the inner wall of the heat-conducting block 41 is provided with multiple mounting grooves, and each mounting groove is embedded with a rubber friction strip. The selection of the magnetic block enables the heat-conducting block 41 to be stably adsorbed onto some workpieces 3, so as to ensure that the heat-conducting block 41 can stably carry out heat transfer. At the same time, the setting of the rubber friction strip enables the entire cooling chain 4 to generate sufficient friction between the workpiece 3 and the workpiece 3, so that the workpiece 3 can be driven to rotate more stably during the movement of the cooling chain 4, so that the workpiece 3 can be smoothly cut and welded.

[0031] As an alternative embodiment, the bottom of the workbench 1 is connected to a carrier plate 16 via a support column 15. The abutment 7 is disposed on the carrier plate 16, which serves as the supporting base of the device. The bottom of the carrier plate 16 is provided with a placement platform, and the bottom of the workbench 1 is provided with a guide rod 741 connected to the abutment block 74. Specifically, the top of the abutment block 74 is provided with a guide hole with an open top. The guide rod 741 extends into the guide hole and is slidably connected to the guide hole. The arrangement of the guide hole and the guide rod 741 enables the abutment block 74 slider 73 to move only upwards, thereby driving the clamping member 22 to stably clamp the workpiece 3 and preventing the abutment block 74 from tilting, which would cause the workpiece 3 to be unable to be stably clamped.

[0032] As an alternative embodiment, such as Figure 3 As shown, the position adjustment part 12 includes a lifting part 121 and a horizontal moving part 122 disposed on the lifting part 121. The cutting mechanism 13 and the welding mechanism 14 are mounted on the horizontal moving part 122. Specifically, both the lifting part 121 and the horizontal moving part 122 are screw-slider mechanisms, and both the cutting mechanism 13 and the welding mechanism 14 are disposed on the slider of the horizontal moving part 122.

[0033] This invention also proposes an industrial electromechanical manufacturing cutting and welding method, comprising the following steps: When it is necessary to cut the workpiece 3, the entire workpiece 3 is passed through the fixed frame 21, and the part of the workpiece 3 to be cut is placed in the middle of the worktable 1. Then, the drive unit 72 is activated to drive the lead screw 71 to rotate, which causes the two sliders 73 threaded on the lead screw 71 to move toward the opposite side. Due to the effect of the inclined plane and under the limit of the guide rod 741, the two sliders 73 push the abutment block 74 to move upward, which in turn causes the abutment block 74 to drive the clamping head to move upward through the push rod. Then, the second abutment post set on the clamping head cooperates with the first abutment post to clamp the workpiece 3. During the upward movement and clamping of the workpiece 3, the workpiece 3 gradually lifts the cooling chain 4, so that the cooling chain 4 is gradually hung on the workpiece 3.

[0034] As the two sliders 73 move toward each other, they push the top block 521 toward the support platform 711. The top block 521 lifts the lifting platform 63 via the first hinge rod 522 to ensure that the rotating wheel 61 on the lifting platform 63 remains in continuous contact with the cooling chain 4. When cutting the workpiece 3, the cutting mechanism 13 is adjusted by the lifting part 121 and the horizontal moving part 122 to cut the workpiece 3. At the same time, the cooling medium flows through the cooling channel to remove the residual heat on the workpiece 3. Simultaneously, the rotary drive 6 is activated so that the rotating shaft of the rotary drive 6 drives the workpiece 3 to rotate via the rotating wheel 61 and the cooling chain 4, thereby completing the cutting of the entire workpiece 3. After the workpiece 3 is cut, the remaining material to be removed is released by the clamping member 22, and then the welded part is clamped and fixed. Then, by continuously raising the lifting platform 63, the two second gears 622 mesh with the two first gears 621, and push the grinding disc 515 to rise. Then, the rotary drive member 6 is activated to drive the grinding disc 515 to grind the welding position of the workpiece 3 through the first gear 621, the second gear 622, the first rotating shaft 512 and the second rotating shaft 513, and to form a welding bevel. At the same time, driven by the cooling chain 4, the work of the entire welding area is completed. After grinding is completed, the grinding disc 515 is lowered.

[0035] Subsequently, during the welding process, the position of the welding mechanism 14 is adjusted by the position adjustment unit 12, and the welding of the workpiece 3 is completed; at the same time, during the welding process, the cooling chain 4 can continuously reduce the impact of the heat-affected zone on the welding quality in the above manner.

[0036] This invention provides an industrial electromechanical manufacturing cutting and welding device. By adopting an integrated cutting-welding device, the production line is transformed: a single workpiece clamping completes the entire sequence of operations, eliminating cycle time waste and error accumulation caused by multiple transfers and repetitive positioning, significantly reducing the processing cycle; on the same motion platform, the cutting and welding energy sources alternate according to the optimal thermal cycle sequence, instantly cooling, actively homogenizing, and rapidly dissipating the heat from the cut; the width of the heat-affected zone and the peak temperature decrease simultaneously, effectively suppressing the hardening tendency and residual stress of high-strength steel and heat-resistant alloys; significantly reducing weld defects such as cracks and porosity; and simultaneously improving post-weld geometric accuracy and surface quality; the merging of processes reduces floor space, molds, and labor input simultaneously, simplifying and streamlining on-site logistics; and achieving high equipment utilization and production flexibility, providing a high-quality, efficient, green, and intelligent new manufacturing paradigm for industries such as steel structures, rail transportation, shipbuilding, and engineering machinery.

9. An industrial electromechanical manufacturing cutting and welding method, based on the industrial electromechanical manufacturing cutting and welding apparatus according to claim 1, characterized in that, Includes the following steps: When it is necessary to cut the workpiece, the entire workpiece is passed through the fixed frame; then the two sets of clamping parts are activated to clamp and fix the workpiece. During the process of the clamping parts clamping and fixing the workpiece from bottom to top, the cooling chain is sleeved on the workpiece. The cutting mechanism is adjusted by the position adjustment unit to cut the workpiece. At the same time, the cooling medium flows in the cooling channel and the heat conduction block removes the residual heat on the workpiece. At the same time, the rotary drive is started so that the rotary drive drives the workpiece to rotate through the rotating wheel and the cooling chain, thus completing the cutting of the workpiece. When welding is required, the excess material to be removed is released by the clamping device, and then the workpiece is clamped and fixed. Subsequently, during the welding process, the position of the welding mechanism is adjusted by the position adjustment unit, and the workpiece is rotated by the cooling chain to complete the welding work.
