This process results in uniform stress distribution and a low weld defect rate, making it widely used in oil and gas transportation, coal slurry pipelines, and offshore platform construction. In the processing of double-sided submerged arc welded straight seam steel pipes, the plate rolling machine is the core equipment for rolling steel plates into cylindrical pipe blanks that conform to the diameter of the steel pipe. During the processing of double-sided submerged arc straight seam welded steel pipes, the steel plate needs to be pre-bent using a plate rolling machine. In the operation of existing plate rolling machines, workers need to use hoisting equipment or multiple workers to hand-load the steel plate into the plate rolling machine, which is quite inconvenient.

[0004] A plate rolling machine for double-sided submerged arc straight seam welded steel pipes includes: a plate rolling machine body, which consists of a base and a rolling roller, wherein the rolling roller is disposed above the base; An auxiliary clamping mechanism is located on the side of the base. The auxiliary clamping mechanism includes a support base and a lifting frame. The support base is bolted to the bottom side wall of one side of the base by bolts. Vertical frames are provided on the top surfaces of both sides of the support base. Each vertical frame is equipped with a lifting component for driving the lifting frame to adjust its height. The upper and lower sides of the opposite side walls of the two sets of lifting frames are provided with protruding plates for supporting and clamping the steel plate.

[0005] In one embodiment, the upper and lower sets of convex plates have multiple grooves on their opposite sidewalls. A spring is installed inside the groove, and the end of the spring is fixedly connected to the bottom end of the adjusting column located inside the groove.

[0006] In one embodiment, the ends of the plurality of adjusting columns are provided with brackets, and rollers are rotatably arranged inside the brackets, with the outer arc surfaces of the rollers in close contact with the surface and bottom surface of the steel plate, respectively.

[0007] In one embodiment, the lifting frame has an internal cavity, and a bidirectional screw is rotatably installed inside the cavity. The outer arc surfaces on both the upper and lower sides of the bidirectional screw are threaded with clamps, and the end of the convex plate passes through a guide groove opened in the side wall of the lifting frame and is fixedly connected to the clamps.

[0008] In one embodiment, the end sidewall of the protruding plate that penetrates the guide groove is in contact with and slidably connected to the inner wall of the guide groove, and the clamping plate is slidably connected to the inner wall of the cavity.

[0009] In one embodiment, the lifting frame is threaded onto the outside of a threaded rod disposed inside the vertical frame on the side wall facing the vertical frame, and the bottom end of the threaded rod is rotatably disposed with the bottom of the vertical frame.

[0010] In one embodiment, one of the vertical frames is fixedly disposed on the surface of the support base, one end surface of the support base is provided with an adjustment groove, and the bottom end of the other vertical frame is slidably connected to the inner wall of the adjustment groove.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0017] The following is combined Figures 1-6 This invention describes a plate rolling machine for double-sided submerged arc straight seam welded steel pipes.

[0018] In one embodiment, a plate rolling machine for double-sided submerged arc straight seam welded steel pipe includes: a plate rolling machine body 100, which is composed of a base 101 and a rolling roller 102, the rolling roller 102 being disposed above the base 101; Additional notes: The model of the plate rolling machine body 100 in this application can be: W12-30×3500-ZF; It includes, but is not limited to, the following structures: work roller, frame, base 101, transmission device, tipping mechanism, and electrical components; An auxiliary clamping mechanism 200 is located on the side of the base 101. The auxiliary clamping mechanism 200 includes a support base 201 and a lifting frame 206. The support base 201 is bolted to the bottom side wall of one side of the base 101 by bolts. Vertical frames 202 are provided on the top surfaces of both sides of the support base 201. Each vertical frame 202 is equipped with a lifting component for driving the lifting frame 206 to adjust its height. The upper and lower sides of the opposite side walls of the two sets of lifting frames 206 are provided with protruding plates 211 for supporting and clamping the steel plate. The support base 201 is fixed to one side bottom of the base 101 by bolts. The auxiliary clamping mechanism 200 is installed on the side of the plate rolling machine body 100. The auxiliary clamping mechanism 200 has a convex plate 211 inside that can clamp and support the steel plate, so that the steel plate can be clamped and supported when it is being loaded, without the need for external hoisting equipment or multiple workers to manually move and load the steel plate. like Figure 4 , Figure 5 and Figure 6 As shown, the upper and lower sets of protruding plates 211 have multiple grooves 213 on their opposite sidewalls. A spring 214 is installed inside the groove 213. The end of the spring 214 is fixedly connected to the bottom end of the adjusting column 212 located inside the groove 213. The ends of multiple adjusting columns 212 are provided with brackets 215, and rollers 216 are rotatably provided inside the brackets 215. The outer arc surfaces of the rollers 216 are in close contact with the surface and bottom surfaces of the steel plate, respectively. In this embodiment, grooves 213 are provided on the opposite sidewalls of the upper and lower sets of convex plates 211. A spring 214 is provided inside the groove 213. The top end of the spring 214 is fixedly connected to the bottom surface of the adjusting column 212 located inside the groove 213. The bottom diameter of the adjusting column 212 located inside the groove 213 is larger than the top diameter of the adjusting column 212. A rotatable roller 216 is provided at the top of the adjusting column 212. When the convex plate 211 is driven by the clamping plate 210 to clamp the steel plate, the roller 216 at the end of the adjusting column 212 first contacts the surface and bottom surface of the steel plate. The adjusting column 212 adapts to different steel plate thicknesses to avoid the convex plate 211 directly and rigidly clamping the steel plate, reducing the friction between the steel plate and the convex plate 211 during the feeding process, which would damage the convex plate 211 and affect its service life. like Figure 4 As shown, the lifting frame 206 has a cavity 207 inside, and a bidirectional screw 208 is rotatably installed inside the cavity 207. The outer arc surfaces on both the upper and lower sides of the bidirectional screw 208 are threaded with clamping plates 210. The end of the protruding plate 211 passes through the guide groove 209 opened in the side wall of the lifting frame 206 and is fixedly connected to the clamping plate 210. The end side wall of the protruding plate 211 passing through the guide groove 209 is in contact with and slidably connected to the inner wall of the guide groove 209. The clamping plate 210 is slidably connected to the inner wall of the cavity 207. In this embodiment, a rotatable bidirectional screw 208 is provided inside the lifting frame 206, and clamping plates 210 are sleeved on the outer arc surfaces of both the upper and lower ends of the bidirectional screw 208. The end of the convex plate 211 passes through the guide groove 209 opened on the side wall of the lifting frame 206 and is fixedly connected to the clamping plate 210. The inner wall of the guide groove 209 is slidably connected to the outer arc surface of the convex plate 211. The clamping plate 210 is slidably connected to the inner wall of the cavity 207. When the bidirectional screw 208 is driven to rotate, it drives the two sets of clamping plates 210 to move in opposite directions, thereby driving the convex plate 211 to clamp and support the steel plate. There is no need for workers to manually support or use external hoisting equipment to support the steel plate, making the operation more convenient. like Figure 2 and Figure 3 As shown, the lifting frame 206 is threaded onto the outside of the threaded rod 203 inside the vertical frame 202, with the side wall facing the vertical frame 202 threaded together. The bottom ends of the threaded rod 203 are rotatably connected to the bottom of the vertical frame 202. One vertical frame 202 is fixedly mounted on the surface of the support base 201. An adjustment groove 204 is provided on one end surface of the support base 201. The bottom end of the other vertical frame 202 is slidably connected to the inner wall of the adjustment groove 204. The outer wall of the support base 201 near the adjustment groove 204 has multiple insertion holes 205, and the vertical frame 202 is inserted into the insertion holes 205 with T-shaped pins. In this embodiment, an adjustment groove 204 is provided on one end surface of the support base 201. One vertical frame 202 is fixedly installed on the surface of the support base 201 away from the adjustment groove 204, and the other vertical frame 202 is slidably installed inside the adjustment groove 204. The side wall of the support base 201 is provided with multiple insertion holes 205 at the position of the adjustment groove 204. When steel plates of different widths need to be pre-bent, the worker pulls out the T-shaped pin inserted into the insertion hole 205, moves the vertical frame 202 to the position inside the adjustment groove 204, and after the movement is completed, inserts the T-shaped pin into the side wall of the vertical frame 202 and the corresponding insertion hole 205 to fix the vertical frame 202, so as to realize the pre-bending of steel plates of different widths.

[0019] Working principle: Before using the plate rolling machine body 100, the worker first installs the support base 201 to the base 101 with bolts; After installation, when the steel plate needs to be pre-bent, the worker adjusts the position of the vertical frame 202 inside the adjustment groove 204 according to the width of the steel plate. After adjustment, the threaded rod 203 is rotated to adjust the height of the two sets of lifting frames 206 according to the thickness of different steel plates. One end of the steel plate is placed inside the protruding plates 211 set on the opposite side walls of the two sets of lifting frames 206. The double-acting screw 208 is rotated so that the rollers 216 at the ends of the protruding plates 211 set on the opposite side walls of the two sets of lifting frames 206 are in close contact with the surface and bottom of the steel plate, thereby clamping and supporting the steel plate. After the steel plate enters the body 100 of the plate rolling machine, the worker can release the steel plate. The steel plate slowly enters the body 100 of the plate rolling machine under the rotation of the rolling roller 102 inside the body 100. There is no need for the worker to continuously manually support the steel plate or use external hoisting equipment to support the steel plate, making the operation more convenient.

[0020] Note: In this application, both the threaded rod 203 and the bidirectional screw 208 are configured as reciprocating screws. The reciprocating screw is manifested as two threaded grooves with the same pitch and opposite directions of rotation, connected at both ends by a transition curve. By rotating the reciprocating screw, the side of the helical groove pushes the slider placed in the helical groove to perform axial reciprocating motion.
