Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a high-efficiency roll welding equipment capable of continuous processing. Background Technology

[0002] In the field of sheet metal processing, roll welding equipment is a key piece of equipment for the automated production of cylindrical workpieces (such as pipes and container bodies), and is widely used in industries such as petrochemicals, engineering machinery, and environmental protection equipment. The core processes of existing roll welding equipment include two steps: sheet metal roll forming and longitudinal weld seam welding. However, current technology has significant shortcomings in terms of equipment integration, processing continuity, and welding accuracy, as detailed below:

[0003] Traditional equipment often employs a "single-station intermittent" processing mode, separating and independently operating the rolling and welding processes. After the sheet metal is formed by the rolling machine, it needs to be manually transported to the welding station or conveyed via a simple conveyor belt. This results in the rolling equipment being idle during the welding process, creating an intermittent "rolling-waiting-welding" production flow. According to industry statistics, the effective processing time of such equipment accounts for only 60%-70%, indicating a significant bottleneck in production capacity. Secondly, existing welding stations generally use fixed supports or simple limiting blocks to position the cylindrical workpieces. During the welding process, thermal deformation or conveyor vibration can easily cause misalignment, resulting in weld seam misalignment exceeding 0.5mm, affecting sealing performance. Although some integrated equipment has a rolling-welding linkage function, it uses a single pushing device to transport workpieces sequentially. The rolling assembly must wait for the previous workpiece to be welded before it can be unloaded, making it impossible to achieve parallel operation of "rolling and welding simultaneously," which does not meet the cost reduction and efficiency improvement requirements of intelligent manufacturing. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a high-efficiency rolling and welding equipment that can continuously process and automatically complete the entire rolling and welding process, with high welding continuity, which can significantly improve production efficiency.

[0005] The technical solution adopted by this utility model is: a high-efficiency rolling and welding equipment capable of continuous processing, including a frame, on which a rolling assembly, a welding assembly, and a pushing assembly are provided; the rolling assembly includes a pair of rolling rollers mounted on the upper end of the frame, and a first motor module for driving the rolling rollers to rotate relative to each other; a support plate with an arc structure is provided below the rolling rollers on the frame, so that the sheet material is output from between the two rolling rollers in a cylindrical structure and falls into the support plate; the welding assembly includes welding frames located at the horizontal ends of the support plate on the frame, each welding frame having an output port for the cylindrical sheet material to pass through, and the conveying of the welding frame... A welding module is provided at the splicing position of the cylindrical plate at the outlet. A positioning frame is provided on the side of the welding frame near the support plate, which is arranged around the welding port. Each positioning frame is arranged along the axial direction of the outlet. Positioning rollers are arranged at intervals on the inner side of the positioning frame, so that the positioning rollers make rolling contact with the outer circumferential surface of the cylindrical plate. The pushing assembly includes a pushing guide rail located below the rolling roller. Both ends of the pushing guide rail extend towards the welding frame on the corresponding side. A guide slider is provided on the pushing guide rail and slides along the arrangement direction of the pushing guide rail. The guide slider can drive the cylindrical plates that fall into the support plate to alternately translate into the corresponding welding frame.

[0006] In this technical solution, the rolling and welding equipment has a rolling assembly and a welding assembly, which can complete the rolling and welding operations sequentially. The sheet material to be rolled is fed between the rolling rollers, and after rolling, it forms a cylindrical structure and falls into the support plate. The pushing assembly located on the frame can push the cylindrical sheet material to the welding frame at the corresponding end through the guide slider. The welding frame is equipped with a positioning frame arranged around the cylindrical sheet material, which can limit the cylindrical sheet material and move it to the welding position. The welding process is automatically completed as the cylindrical sheet material moves towards the output end. By setting the welding assembly at both ends of the rolling assembly and using the pushing assembly to achieve alternating feeding of each welding module, this technical solution can improve welding efficiency and allow the rolling assembly to continuously process without waiting for welding to be completed, significantly improving production efficiency.

[0007] Preferably, the rolling roller is connected to a first motor module via a reducer module.

[0008] Preferably, the frame is provided with a plurality of input frames arranged at intervals along the axial direction of the rolling roller at the input end of the rolling roller, and the input frames are provided with input wheel sets arranged at intervals. When the sheet material is input into the rolling roller from the input frame, the input wheel sets make rolling contact with the lower surface of the sheet material.

[0009] Preferably, the positioning frame is provided with a plurality of clamping roller groups arranged around the output port. The clamping roller groups include clamping rollers arranged in pairs. The two ends of the clamping rollers are rotatably engaged with clamping seats installed on the welding frame. The curvature of the outer circumference of the clamping rollers is adapted to the curvature of the outer circumference of the cylindrical plate.

[0010] Preferably, the positioning frame is provided downstream of the welding module with an output guide wheel that can contact the outer periphery of the cylindrical plate, and the output guide wheel is connected to a second motor module via a transmission shaft.

[0011] Preferably, the frame has a supporting cylinder arranged coaxially with the output port, and the supporting cylinder can abut against the inner circumferential wall of the cylindrical plate.

[0012] Preferably, the frame includes a rolling frame for mounting the rolling assembly, welding bases for mounting welding frames are provided at both horizontal ends of the rolling frame, and support bases are also installed at the lower ends of the rolling frame and the welding bases, with spaced support beams at the lower ends of the support bases.

[0013] Preferably, the support base is provided with adjustable guide rails at both ends, which are arranged in opposite directions along its length. The adjustable guide rails are slidably engaged with the welding base, and the welding frame is provided with adjusting bolts.

[0014] The beneficial effects of this utility model are as follows: This utility model drives the cylindrical plate to alternately move between the support plate and the welding frames on both sides through the guide slider of the pushing assembly, realizing the parallel operation of "rolling-welding". The rolling assembly can continuously feed materials without waiting for the previous welding to be completed, completely breaking the intermittent production bottleneck of the traditional equipment of "rolling-waiting-welding", and improving production efficiency by more than 40%. High-precision flexible positioning is adopted to ensure the stability of welding quality. The positioning rollers arranged at intervals on the inner side of the positioning frame of the welding frame are also used to roll and contact the outer circumference of the cylindrical plate, forming a flexible limit constraint. It can adapt to workpieces of different diameters and can switch product specifications without changing hardware, significantly shortening the changeover time. The rolling assembly, welding assembly and pushing assembly are linked in real time through the electrical control system. After the rolling roller outputs the workpiece, it is immediately pushed to the welding station by the guide slider, effectively reducing the manual intervention rate. Attached Figure Description

Detailed Implementation

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0023] like Figures 1 to 4 As shown in the figure, a specific embodiment of the present invention provides a high-efficiency rolling and welding equipment capable of continuous processing, including a frame on which a rolling assembly 100, a welding assembly 200 and a pushing assembly 300 are provided, thereby enabling continuous and efficient completion of rolling and welding processing.

[0024] like Figure 1 As shown, the rolling assembly 100 in this embodiment includes a pair of rolling rollers 110 mounted on the upper end of the frame and a first motor module 120 for driving the rolling rollers 110. The rolling rollers 110 are connected to the first motor module 120 via a reducer module. A support plate 130 with an arc structure is provided below the rolling rollers 110 on the frame, so that the sheet material, after being output between the two rolling rollers 110, forms a cylindrical structure and falls into the support plate 130. Thus, when the first motor module 120 drives the rolling rollers 110, the rolling rollers 110 can roll the fed sheet material into a cylindrical structure. After the rolling process is completed, the cylindrical sheet material falls into the support plate 130 for subsequent welding. In practical applications, a reduction module structure is provided between the first motor module and the rolling rollers 110 to form a stable transmission structure and ensure the stability of the rolling process; this will not be elaborated further here.

[0025] like Figure 2 As shown, the welding assembly 200 in this embodiment includes welding frames 210 located at both horizontal ends of the support plate 130 of the frame. Each welding frame 210 has an output port for the cylindrical plate to pass through. A welding module 220 is provided at the output port of the welding frame 210 corresponding to the splicing position of the cylindrical plate. A positioning frame 230 is provided on the side of the welding frame 210 near the support plate 130, arranged around the welding port. Each positioning frame 230 is arranged axially along the output port. Positioning rollers 240 are arranged at intervals on the inner side of the positioning frame 230, so that the positioning rollers 240 are in contact with the outer surface of the cylindrical plate. Circumferential rolling contact; thus, welding modules 220 are set on the welding frames 210 on both sides of the support plate, corresponding to the splicing positions of the cylindrical plates. The positioning frame 230 can move the cylinder along the output port axial direction through the positioning rollers 240. During the movement, welding is continuously performed through the welding modules 220. After welding is completed, the cylinder is automatically output from the welding frame 210. The rolling contact design of the positioning rollers solves the defects of traditional rigid positioning: it limits the radial displacement of the cylinder (misalignment ≤ 0.2mm) and reduces the transfer resistance through rolling friction, avoiding weld deviation caused by thermal deformation or vibration.

[0026] like Figure 3 As shown, since the device has welding assemblies 200 on both sides of the rolling assembly 100, continuous welding can be achieved by alternately feeding the rolled cylindrical plates into one of the welding assemblies 200 during welding. Specifically, the pushing assembly 300 includes a pushing guide rail 310 located below the rolling roller 110. The two ends of the pushing guide rail 310 extend toward the welding frame 210 on the corresponding side. The pushing guide rail 310 is provided with a guide slider 320 that slides along the arrangement direction of the pushing guide rail 310. The guide slider 320 can drive the cylindrical plates that fall into the support plate 130 to alternately move into the corresponding welding frame 210. In this way, the push assembly 300 located on the frame can push the cylindrical plate into the welding frame 210 at the corresponding end through the guide slider 320. During the conveying process, the positioning roller 240 limits the cylindrical plate and moves it to the welding position. The cylindrical plate automatically completes the welding process as it moves towards the output end. By setting the welding assembly 200 at both ends of the rolling assembly 100, the push assembly 300 can achieve alternating feeding of each welding module 220, which helps to improve welding efficiency. The rolling assembly 100 can be continuously processed without waiting for the welding to be completed, which significantly improves production efficiency. In practical applications, the guide slider can be driven by a screw module, cylinder module or other drive structure to achieve reciprocating drive, which significantly improves welding efficiency by alternating feeding of the welding assembly.

[0027] like Figure 4As shown above, during the rolling process, the sheet material needs to be placed into the rolling roller 110 from the input end. To facilitate the input of the sheet material, this embodiment provides several input frames 140 arranged at intervals along the axial direction of the rolling roller 110 at the input end of the frame corresponding to the input end of the rolling roller 110. Each input frame 140 is equipped with an input wheel set 150 arranged at intervals. When the sheet material is input into the rolling roller 110 from the input frame 140, the input wheel set 150 makes rolling contact with the lower surface of the sheet material. In this way, after the sheet material is placed into the input frame 140, it can be horizontally pushed between the rolling rollers 110. The input wheel set 150 reduces the pushing friction, improving the smoothness and stability of the sheet material input.

[0028] like Figure 2 As shown, during the welding process, the welding assembly 200 needs to ensure stable contact between the splicing positions of the sheet metal and the welded parts to avoid problems such as welding deformation or uneven welding. In this embodiment, the positioning frame 230 is equipped with several clamping roller groups 250 arranged around the output port. The clamping roller group 250 includes a pair of clamping rollers, and the two ends of the clamping rollers are rotatably engaged with the clamping seats 260 mounted on the welding frame 210. The curvature of the outer circumference of the clamping rollers is adapted to the curvature of the outer circumference of the cylindrical sheet metal. In this way, during the welding process, the cylindrical sheet metal can be uniformly clamped to the outer circumference of the sheet metal by the clamping rollers, ensuring the stability of the splicing position of the cylinder and the positional accuracy of the welding process, and avoiding the occurrence of excessive gaps during the welding process.

[0029] like Figure 2 As shown, to enable the cylinder to be output while welding, this embodiment provides an output guide wheel 270 downstream of the positioning frame 230 corresponding to the welding module 220, which can contact the outer periphery of the cylindrical plate. The output guide wheel 270 is connected to a second motor module 280 via a drive shaft. When the second motor module 280 is running, it can drive the output guide wheel 270 to rotate, and when the output guide wheel 270 rotates, it can output the cylinder from the output port of the welding machine. At the same time, this embodiment also provides a support cylinder 290 coaxially arranged with the output port within the frame corresponding to the output port. The support cylinder 290 can abut against the inner peripheral wall of the cylindrical plate. The support cylinder 290 can support the cylindrical plate and, under the clamping action of the clamping rollers, ensure that the cylinder maintains its shape during the welding process, avoiding defects such as deformation and loss of roundness during processing.

[0030] like Figure 4As shown, the frame as a whole is used to support the entire structure. The frame provided in this embodiment includes a rolling frame 400 for mounting the rolling assembly 100. The rolling frame 400 has welding bases 500 for mounting welding frames 210 at both horizontal ends. The rolling frame 400 and the welding bases 500 are also equipped with support bases 600 at their lower ends. The support bases 600 have spaced support beams 700 at their lower ends. Thus, the rolling frame 400 can be used to install the rolling assembly 100, and the welding frame 210 is used to install the welding assembly 200. The entire structure is stably supported by the bottom support base 600, and the stability of the equipment during operation is ensured by the support beam 700. In practical applications, when welding cylindrical plates of different specifications, the distance between the welding assembly 200 and the rolling assembly 100 is different. To facilitate the adjustment of the distance between the welding assembly 200 and the rolling assembly 100, this embodiment has adjusting guide rails 800 arranged along its length at both ends of the support base 600. The adjusting guide rails 800 are slidably engaged with the welding base 500, and the welding frame 210 is provided with adjusting bolts. In this way, the welding frame 210 can slide along the adjusting guide rails 800, thereby realizing the adjustment of the position of the welding frame 210. After adjustment, the welding frame 210 can be fixed by adjusting bolts.

[0031] In practical applications, a controller structure, such as a PLC controller, should also be set up to input control commands. The controller structure is connected to the signals of each electrical device, so that the entire device can be automated according to the control program.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
