Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and particularly relates to a welding machine device with a punching edge function. Background Art

[0002] In the process of continuous production of cold-rolled strip steel and hot-rolled strip steel, it is usually necessary to connect multiple sections of strip steel to ensure the continuity and high efficiency of the production line. Welding can ensure seamless connection between strip steels, avoid production interruption, reduce the frequency of replacing strip steel, improve production efficiency, and reduce production costs.

[0003] When connecting two sections of strip steel, a welding device is used. First, the heads and tails of the two sections of strip steel are butted together, and the heads and tails of the two strip steels are welded together by a welding machine to form a weld. The welding machine adopts the principle of resistance roller welding. The main circuit is composed of an upper welding wheel and the overlapping part of the strip steel. Its welding principle is that two strip steels are overlapped and passed through an appropriate current, and heat is generated on the resistance of the material itself, the concentrated resistance at the contact part between materials and between materials and electrodes, and finally they are melted and welded together. After completion, the strip steel is run to the edge cutting shear to perform destructive edge cutting on the edge of the strip steel, and then a punching cup convexity test needs to be carried out on the cut edge to check whether the weld quality meets the requirements.

[0004] If the two sections of strip steel are not neatly overlapped during the welding process, it will lead to a reduction in the welding contact area, thereby reducing the welding strength, resulting in uneven stress distribution, causing stress concentration at the welding position, increasing the brittleness of the welding part, and reducing its tensile strength and durability. This will make the welding part more prone to quality problems such as fracture and pores. Summary of the Invention

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0023] As Figures 1 to 7 shown, this embodiment proposes a welding machine device with an edge trimming function, including an equipment frame 1. A feeding frame 2 is fixedly installed at the input end of the equipment frame 1, and a discharging frame 3 is fixedly installed at the output end of the equipment frame 1. It also includes a cleaning frame 4, a cleaning component, a position adjustment frame 5, a welding component, an edge trimming component and a position adjustment component. The cleaning frame 4 is fixedly installed on the feeding frame 2. The cleaning component is installed on the cleaning frame 4 and is used to clean the upper and lower sides of the strip before welding at the same time. The cleaning component includes a brush 6 and a driving part. Two brushes 6 are symmetrically and rotatably installed up and down inside the cleaning frame 4. The driving part is installed on the cleaning frame 4 and is used to drive the two brushes 6 to rotate in opposite directions.

[0024] Specifically, when welding two strips of steel, when the end of the first strip of steel moves to the discharging rack 3 and protrudes a part, the position-adjusting component is started to fix the first strip of steel. Then, a new coil of steel strip is installed on the loading equipment, and the front end of the new coil of steel strip is fed into the cleaning rack 4. Under the action of the driving part, the two brushes 6 are driven to rotate in opposite directions, so as to clean the upper and lower surfaces of the steel strip simultaneously to remove impurities such as dust and oxide layer on the steel strip. After passing through the cleaning rack 4, the steel strip will enter the equipment rack 1. When the second strip of steel protrudes a part from the feeding rack 2, the second strip of steel is fixed. At this time, an overlapping area appears between the first strip of steel and the second strip of steel. At this time, the welding component is started, and through the cooperation with the position-adjusting component, the overlapping position between the two strips of steel is welded. After welding, the edge of the steel strip needs to be processed by edge cutting. Through the setting of the edge punching component, the edge of the steel strip is destructively cut. After completion, the punched edge needs to be subjected to a cupping test to check whether the weld quality meets the requirements. If the cupping test is unqualified, the weld needs to be sheared and welded again.

[0025] As described above, Figure 3 As shown, the driving part includes a transmission gear 7 and a first motor 8. Transmission gears 7 are fixedly installed at both ends of the two brushes 6, and every two adjacent transmission gears 7 are meshed. The first motor 8 is fixedly installed on the cleaning component, and the output end of the first motor 8 is fixedly connected to one of the transmission gears 7.

[0026] Specifically, when cleaning the steel strip, the first motor 8 is started, and the first motor 8 drives one of the transmission gears 7 to rotate. Through the cooperation between the multiple transmission gears 7, the two brushes 6 are driven to rotate simultaneously, and the brush hairs of the brushes 6 clean the steel strip.

[0027] It should be added that after using for a period of time, in order to maintain a good cleaning effect, the brushes 6 need to be cleaned or replaced.

[0028] As Figure 4 shown, two position-adjusting racks 5 are symmetrically and fixedly installed inside the equipment rack 1 up and down. Welding components are installed on the two position-adjusting racks 5, and the two welding components are symmetrically arranged for welding two strips of steel. The welding component includes a sliding rack 9, a moving rack 10, a first hydraulic cylinder 11 and a welding part. The sliding racks 9 are slidably installed on the two position-adjusting racks 5, the moving racks 10 are slidably installed on the two sliding racks 9, the first hydraulic cylinders 11 are fixedly installed on the two sliding racks 9, the output ends of the first hydraulic cylinders 11 are fixedly connected to the moving racks 10, and the welding part is installed on the two moving racks 10 for welding the steel strip.

[0029] Specifically, when welding two strips of steel, first move the two sliding frames 9 synchronously to the overlapping position of the two strips of steel. At this time, start the first hydraulic cylinders 11 on the two sliding frames 9 respectively, so as to push the two moving frames 10 to move in the opposite direction until the welding parts on the tops of the two moving frames 10 are in contact with the overlapping position of the two strips of steel. At this time, drive the two sliding frames 9 to move synchronously. The two sliding frames 9 drive the moving frames 10 to move, and at the same time start the welding part to weld the two strips of steel. When the sliding frame 9 moves to the other end of the positioning frame 5 and the welding part moves out of the position of the strip of steel, the welding can be completed.

[0030] As described above, such as Figure 4 shown, the welding part includes a welding machine body 12. The welding machine bodies 12 are fixedly installed on the two moving frames 10. Welding wheels 13 are fixedly installed at the output ends of the two welding machine bodies 12. The welding wheels 13 are rotatably connected to the moving frames 10. It also includes abutting wheels 14. Two abutting wheels 14 are symmetrically and rotatably installed on each of the two moving frames 10.

[0031] Specifically, when welding two strips of steel, as the two moving frames 10 move in the opposite direction, the two moving frames 10 respectively push the corresponding welding wheels 13, welding machine bodies 12 and abutting wheels 14 to move until one of the two abutting wheels 14 on the two moving frames 10 abuts against the strip of steel, then the welding machine body 12 can be started. As the two sliding frames 9 move synchronously, the overlapping position of the two strips of steel is more easily welded after being rolled by the two abutting wheels 14 in the front in the moving direction. Subsequently, the welding wheel 13 contacts the strip of steel, and the two strips of steel can be welded together. Under the action of the two abutting wheels 14 at the rear, the welding position of the two strips of steel is rolled, and the welding stability can be improved.

[0032] As Figure 4 、 Figure 5 shown, the edge trimming assembly is installed on the welding assembly and is used for edge trimming and sampling of the welded strip of steel. The edge trimming assembly includes a second hydraulic cylinder 15, a mounting frame 16, an edge trimming knife 17 and a collection box 18. The second hydraulic cylinders 15 are fixedly installed on both sides of the two moving frames 10. The second hydraulic cylinders 15 on both sides of the two moving frames 10 are symmetrically arranged. The output ends of the four second hydraulic cylinders 15 are fixedly installed with mounting frames 16. The edge trimming knives 17 are detachably installed on the four mounting frames 16. Collection boxes 18 are fixedly installed on both sides of the bottom moving frame 10. The two collection boxes 18 are symmetrically arranged. It also includes a top frame 19 and a spring 20. The top frames 19 are slidably installed on the four mounting frames 16. Springs 20 are fixedly installed between the four mounting frames 16 and the four top frames 19.

[0033] Specifically, after welding, the strip steel needs to be edge-trimmed. At this time, the first hydraulic cylinder 11 is retracted, and the two sliding frames 9 are simultaneously moved to the edge-trimming position. The second hydraulic cylinders 15 on the same side of the two moving frames 10 are respectively started. The second hydraulic cylinders 15 push the mounting frames 16 to move, and the mounting frames 16 drive the edge-trimming knives 17 to move until the two edge-trimming knives 17 are both in contact with the welding positions of the two sections of strip steel. At this time, under the action of the two second hydraulic cylinders 15, the strip steel is edge-trimmed by the edge-trimming knives 17. When the top frame 19 and the edge-trimming knives 17 are simultaneously in contact with the strip steel, as the second hydraulic cylinders 15 continue to move, the spring 20 at this time is compressed, and relative movement occurs between the top frame 19 and the mounting frame 16 until after the strip steel is edge-trimmed by the two edge-trimming knives 17, the second hydraulic cylinders 15 are retracted. At this time, under the pressure of the spring 20, the spring 20 pushes out the strip steel that may be stuck in the edge-trimming knives 17 through the top frame 19, and the pushed-out strip steel will enter the collection box 18 at the corresponding position. Repeat the above steps to edge-trim the other side of the strip steel. Until after edge-trimming is completed, the two sections of specimens punched off are subjected to a cupping test to check whether the weld quality meets the requirements. As Figure 6 shown, the position adjustment assembly is installed on the equipment frame 1 and is used to adjust the position of the welding assembly. The position adjustment assembly includes a driving lead screw 21, a transmission nut 22, a second motor 23, a welding positioning part, and a moving guiding part. Driving lead screws 21 are rotatably installed inside the two position adjustment frames 5, transmission nuts 22 are threadedly sleeved on the two driving lead screws 21, the two transmission nuts 22 are respectively fixedly connected to the bottoms of the two sliding frames 9, two second motors 23 are fixedly installed on the equipment frame 1, and the output ends of the two second motors 23 are respectively fixedly connected to the two driving lead screws 21. A welding positioning part is installed inside the equipment frame 1 and is used to fix the strip steel during welding. Moving guiding parts are installed on the feeding frame 2 and the discharging frame 3 and are used to straighten the strip steel.

[0034] Specifically, when it is necessary to drive the two sliding frames 9 to move synchronously, the two second motors 23 need to be started synchronously. The two second motors 23 are highly coordinated with each other, so that the two driving lead screws 21 rotate synchronously. Through the cooperation of the driving lead screw 21 and the transmission nut 22, the sliding frame 9 can be driven to move.

[0035] As described above, as Figure 2 shown, the welding positioning part includes a first electric cylinder 24 and a positioning plate 25. First electric cylinders 24 are symmetrically and fixedly installed inside the equipment frame 1, two positioning plates 25 are symmetrically and slidably installed inside the equipment frame 1, and the positioning plates 25 are fixedly connected to the output ends of the first electric cylinders 24.

[0036] Specifically, when it is necessary to fix two strips of steel, the first electric cylinder 24 at the corresponding position is started. The first electric cylinder 24 drives the positioning plate 25 to move. The two positioning plates 25 correspond to the feeding rack 2 and the discharging rack 3 respectively. Through the cooperation between the two, the strip of steel can be fixed.

[0037] As described above, Figure 7 As shown in the figure, the moving guiding part includes a guiding frame 26, a second electric cylinder 27 and guiding wheels 28. Two guiding frames 26 are symmetrically and slidably installed on both the feeding rack 2 and the discharging rack 3. Two second electric cylinders 27 are symmetrically and slidably installed on both the feeding rack 2 and the discharging rack 3. The output end of the second electric cylinder 27 is fixedly connected to the guiding frame 26. Two guiding wheels 28 are symmetrically and rotatably installed on each guiding frame 26.

[0038] Specifically, during the process of moving the strip of steel, the second electric cylinders 27 on both sides of the feeding rack 2 or the discharging rack 3 need to be started synchronously. The second electric cylinder 27 drives the guiding frame 26 to move. The guiding frame 26 drives the guiding wheels 28 to move until the guiding wheels 28 contact the strip of steel, so as to correct the moving direction of the strip of steel, thereby reducing the problem of deviation at the overlapping position between the two strips of steel and improving the welding quality.

[0039] The working principle or usage process of this application is as follows: When welding two strips of steel, when the end of the first strip of steel moves to the discharging rack 3 and protrudes a part, the first electric cylinder 24 at the corresponding position is started. The first electric cylinder 24 drives the positioning plate 25 to move. The positioning plate 25 fixes the strip of steel through the cooperation with the discharging rack 3. Then, a new coil of strip of steel is installed on the feeding device, and the front end of the new coil of strip of steel is sent into the cleaning rack 4. At this time, the first motor 8 is started. The first motor 8 drives one of the transmission gears 7 to rotate. Through the cooperation between the multiple transmission gears 7, two brushes 6 are driven to rotate simultaneously. The bristles of the brushes 6 clean the upper and lower surfaces of the strip of steel at the same time to remove impurities such as dust and oxide layer on the strip of steel. After passing through the cleaning rack 4, the strip of steel will enter the equipment rack 1. When the second strip of steel protrudes a part from the feeding rack 2, the first electric cylinder 24 at the corresponding position is started, and the second strip of steel can be fixed through the cooperation between the positioning plate 25 and the feeding rack 2. During the process of moving the strip of steel, the second electric cylinders 27 on both sides of the feeding rack 2 or the discharging rack 3 are started synchronously. The second electric cylinder 27 drives the guiding frame 26 to move. The guiding frame 26 drives the guiding wheels 28 to move until the guiding wheels 28 contact the strip of steel, so as to correct the moving direction of the strip of steel, thereby reducing the problem of deviation at the overlapping position between the two strips of steel.

[0040] At this time, the first strip steel and the second strip steel are in an overlapping position, and welding can be started. When welding the two strip steels, first move the two sliding frames 9 synchronously to the overlapping position of the two strip steels, and start the two second motors 23 synchronously. The two second motors 23 are highly coordinated in height, so that the two driving lead screws 21 rotate synchronously. Through the cooperation of the driving lead screw 21 and the transmission nut 22, the sliding frame 9 can be driven to move. After moving to the working position, start the first hydraulic cylinders 11 on the two sliding frames 9 respectively, so as to push the two moving frames 10 to move in the reverse direction. As the two moving frames 10 move in the reverse direction, the two moving frames 10 respectively push the corresponding welding wheels 13, the welding machine body 12 and the abutting wheels 14 to move until one of the two abutting wheels 14 on the two moving frames 10 contacts the strip steel, and then the welding machine body 12 can be started. As the two sliding frames 9 move synchronously, the overlapping position of the two strip steels is more easily welded after being rolled by the two abutting wheels 14 in the front in the moving direction. Subsequently, when the welding wheel 13 contacts the strip steel, the two strip steels can be welded together. Under the action of the two abutting wheels 14 at the rear, the welding position of the two strip steels is rolled, so as to improve the welding stability and complete the welding.

[0041] After welding, the strip steel needs to be edge-cut. At this time, retract the first hydraulic cylinder 11, move the two sliding frames 9 to the edge-cutting position at the same time, and start the second hydraulic cylinders 15 on the same side of the two moving frames 10 respectively. The second hydraulic cylinders 15 push the mounting frames 16 to move, and the mounting frames 16 drive the edge-cutting knives 17 to move until both edge-cutting knives 17 contact the welding position of the two strip steels. At this time, under the action of the two second hydraulic cylinders 15, the strip steel is edge-cut by the edge-cutting knives 17. When the top frame 19 and the edge-cutting knives 17 contact the strip steel at the same time, as the second hydraulic cylinder 15 continues to move, the spring 20 is compressed at this time, and relative movement occurs between the top frame 19 and the mounting frame 16 until after the strip steel is edge-cut by the two edge-cutting knives 17, retract the second hydraulic cylinder 15. At this time, under the pressure of the spring 20, the spring 20 pushes out the strip steel that may be stuck in the edge-cutting knife 17 through the top frame 19, and the pushed-out strip steel will enter the collection box 18 at the corresponding position. Repeat the above steps to edge-cut the other side of the strip steel until after edge-cutting, perform a cupping test on the two cut specimens to check whether the weld quality meets the requirements. If the cupping test is unqualified, the weld needs to be sheared and welded again.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
