[0001] The utility model relates to the technical field of welded pipe production, in particular to a welded pipe line roller. Background Art
[0002] Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip after curling and welding. The production process of welded steel pipe is simple, the production efficiency is high, the variety and specifications are many, and the equipment investment is small. The process flow of welded pipe includes raw material uncoiling, flattening, end shearing and welding, looping, forming, welding, internal and external weld bead removal, pre-correction, induction heat treatment, sizing and straightening, eddy current testing, cutting, water pressure inspection, pickling, final inspection (strict control), packaging and shipment.
[0003] At present, the welding pipe equipment on the market are all automated welding lines designed based on the technology of steel pipe welding pipe and stainless steel welding pipe. Due to the high standard requirements of titanium welded pipes and the properties of titanium, the technical requirements for the surface of the pipe and the difficulty in forming during the forming process are determined.
[0004] At present, the domestic thin-walled titanium welded pipe forming rollers generally use large-diameter copper rollers. Due to the expensive raw materials, the production cost of the rollers has increased significantly, and it is not conducive to maintenance. Some also use nylon rollers. Although the cost is reduced, the deformation and pressure bearing capacity of large-diameter pipelines is insufficient, and the forming requirements of the weld line cannot be met.
[0005] Therefore, it is necessary to provide a welding pipe line roller to solve the above technical problems. Utility Model Content
[0006] The utility model provides a welding pipe line roller, which solves the problem that the raw materials of copper rollers are expensive and the production cost is increased, and the nylon rollers with lower costs cannot meet the use requirements.

[0017] The utility model provides a welding pipe line roller, which cooperates with each other through structures such as an arc surface forming part, an axis part, a differential ratio part, a pressing part, an arc surface pressure arc surface forming part, a positioning part and a limit part. When in use, the arc surface forming part rotates under pressure and the pipeline is dragged by the bottom arc surface, so that the pipeline will not be strained due to the different linear speeds of the circumferential tangent during the welding pipe forming process, and the roller will not be damaged due to the outer ring speed of the roller being faster than the inner ring speed of the roller, thereby avoiding the need to replace the roller and avoiding the wear of the welding pipe caused by the roller, thereby reducing production costs.

DETAILED DESCRIPTION
[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0025] First embodiment
[0026] Please refer to Figure 1 , Figure 2 ,in, Figure 1 A schematic structural diagram of a first embodiment of a welding pipe line roller provided by the utility model; Figure 2 for Figure 1 The exploded structure schematic diagram is shown. A welding pipe line roller comprises: a curved surface forming part 1;
[0027] The shaft member 2 is arranged on the inner side of the arc surface forming member 1, and differential proportioning members 3 are arranged on both sides of the shaft member 2, and clamping members 4 are arranged on one side of the two differential proportioning members 3, and arc surface pressure arc surface forming members 5 are arranged on the outer side of the two clamping members 4, and positioning members 6 are arranged on one side of the two arc surface pressure arc surface forming members 5.
[0028] A limiting member 7 is disposed inside the positioning member 6 and the pressing member 4 , and one end of the limiting member 7 is threadedly connected to the inside of the end surface of the shaft member 2 .
[0029] The arc-shaped part 1 is made of alloy tool steel Cr12MoV alloy.
[0030] The surface of the arc-shaped forming part 1 is arc-shaped.
[0031] The shaft member 2, the differential matching member 3, the pressing member 4, the arc surface 5 and the positioning member 6 are all made of copper alloy material.
[0032] The working principle of a welding pipe line roller provided by the utility model is as follows:
[0033] When in use, the user inserts the shaft member 2 into the inner side of the arc surface forming member 1, and then respectively arranges the two differential proportioning members 3 at the two ends of the shaft member 2, and at the same time, the two differential proportioning members 3 are also at the two ends of the arc surface forming member 1, and then the user presses the two clamping members 4 on one side of the two differential proportioning members 3, and then the user sleeves the two arc-shaped members 5 on the outer sides of the two differential proportioning members 3 and the two clamping members 4, and then the user inserts one end of the two positioning members 6 into the inside of one side of the two arc surface pressure arc surface forming members 5, and then the user passes the limiting member 7 through the inside of the positioning member 6 and the clamping member 4, until one end of the limiting member 7 is threadedly connected to the inside of the shaft member 2, thereby installing the arc surface forming member 1, the shaft member 2, the differential proportioning member 3, the clamping member 4, the arc surface pressure arc surface forming member 5 and the positioning member 6;
[0034] When used for a long time, the outer side of the arc surface forming part 1 is severely worn and rubs against the surface of the welded pipe, causing damage to the welded pipe. The user can rotate the limit member 7 to make one end of the limit member 7 come out from the internal thread connection of the shaft member 2, and then disassemble the positioning member 6, the arc surface pressure arc surface forming part 5, the clamping member 4, the differential matching member 3 and the shaft member 2 respectively, and then disassemble and replace the arc surface forming part 1. In this way, the need to replace the entire roller can be avoided, and only the arc surface forming part 1 needs to be replaced, thereby reducing the production cost.

[0036] The arc surface forming part 1, the shaft part 2, the differential matching part 3, the pressing part 4, the arc surface pressure arc surface forming part 5, the positioning part 6 and the limit part 7 cooperate with each other. When in use, the arc surface forming part 5 rotates under pressure and the pipeline is dragged by the bottom arc surface. The pipeline will not be strained due to the different linear speeds of the circumferential tangent during the welding pipe forming process, and the roller will not be damaged due to the outer ring speed of the roller being faster than the inner ring speed of the roller, thereby avoiding the need to replace the roller and avoiding the wear of the welding pipe caused by the roller, thereby reducing production costs.

[0041] The inner side surfaces of the through slot 82 and the groove 81 are both provided with mounting screws 83 .
[0042] A threaded hole for threaded connection of a mounting screw 83 is provided on the rotating shaft for mounting the roller. A plurality of threaded holes can be provided according to the usage conditions to facilitate the mounting of the roller. In this way, when mounting the roller, the user can directly thread one end of the mounting screw 83 onto the inner side of the threaded hole to mount the roller.
[0043] By setting the groove 81, when in use, the nut of the mounting screw 83 can be stored in the inner side of the groove 81, thereby avoiding being exposed to the outside and subsequently affecting the normal rotation of the roller.
[0044] The working principle of a welding pipe line roller provided by the utility model is as follows:

[0046] Compared with the related art, the welding line roller provided by the utility model has the following beneficial effects:
[0047] Through the cooperation of the structures such as the shaft core 2, the mounting ring 8, the groove 81, the through groove 82 and the mounting screw 83, when in use, one end of the mounting screw 83 is passed through the groove 81 and the through groove 82 respectively, and then one end of the mounting screw 83 is threadedly connected to the inner side of the threaded hole, so that the roller can be installed. This makes it convenient for the user to subsequently install and disassemble the roller, thereby facilitating the user's use.
