[0002] The patent with authorization announcement number CN210676463U discloses a straight seam welded pipe forming frame, including a forming frame body. The forming frame body includes a middle frame and end frames integrally connected to both ends of the middle frame. Each end frame has a flat part at its outer end. The top surface of the flat part is flat. The middle frame has an upward convex arc. The end frames and the middle frame are connected by an arc-shaped transition. In the straight seam welded pipe forming process, the edge of the strip steel is pre-formed, which to a certain extent eliminates the edge stress of the strip steel and the overall stress of the welded pipe. It can effectively reduce the curvature of the product after pipe making, improve the straightening effect, and improve the straightness of the final product.

[0003] The straight seam welded pipe forming frame in the aforementioned patent does not address how to ensure the stability of the strip steel during the forming process. Therefore, it cannot guarantee the forming effect of the strip steel, thereby increasing the defect rate after forming and affecting the forming quality.

[0004] Therefore, this application proposes a straight seam welded pipe forming frame. Utility Model Content

[0005] This application proposes a straight seam welded pipe forming frame to solve the problems mentioned in the background art. When the strip steel is conveyed to the forming machine for forming, it drives the circular seat to rotate on the circular disk, causing the strip steel in the groove to wind around the arc-shaped vertical plate. Subsequently, the strip steel wound on the arc-shaped vertical plate will rotate on the circular seat through the circular rod, causing the strip steel to be conveyed around the circular rod towards the forming machine. During the strip steel conveying process, the strip steel will be provided with the correct direction through the guide rod, so as to ensure the precise conveying position of the strip steel during the forming process of the straight seam welded pipe, improve the quality after forming, reduce the defect rate, and greatly improve the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A straight seam welded pipe forming frame includes a support frame, a rotating frame, and a guide rod. The support frame consists of an annular frame, a circular disc, support plates, and arc-shaped support plates. Multiple support plates are fixedly connected to the outside of the circular disc. Each support plate is fixedly connected to the annular frame on the side away from the circular disc, and the circular disc is fixedly connected to the inside of the annular frame through multiple support plates.

[0008] In a preferred embodiment, the annular frame has a groove inside, and a strip steel is disposed inside the annular frame, with the strip steel placed inside the groove;

[0009] By creating grooves within the annular frame, the strip steel is positioned within these grooves during straight seam welded pipe forming, allowing for the storage of large quantities of strip steel and thus enhancing the device's practicality.

[0010] In a preferred embodiment, the annular frame is externally fixedly connected with multiple arc-shaped support plates, each of which is welded to the annular frame.

[0011] By fixing multiple arc-shaped support plates to the outside of the ring frame, the stability and support of the ring frame are improved, thereby enhancing the practicality of the device.

[0012] In a preferred embodiment, the rotating frame includes an outer support, which is composed of a circular base, an arc-shaped upright plate, and a hollow ring. The circular base is disposed on the top of the circular disk, and a first connecting rod is fixedly connected inside the circular base, with the bottom end of the first connecting rod rotatably connected to the inside of the circular disk.

[0013] By setting a first connecting rod between the circular base and the circular disk to connect the two and simultaneously achieve a rotational effect, the practicality of the device is improved.

[0014] In a preferred embodiment, a plurality of arc-shaped upright plates are fixedly connected to the top of the circular base, each of the arc-shaped upright plates being located at the top edge of the circular base, and the outer surface of each of the arc-shaped upright plates being arc-shaped.

[0015] By setting multiple arc-shaped vertical plates between the circular seat and the hollow ring for winding the strip steel, the special shape of the arc-shaped vertical plates can ensure that the strip steel is not easily affected and deformed, thereby improving the practicality of the device.

[0016] In a preferred embodiment, a hollow ring is fixedly connected to the top of each of the arc-shaped uprights, and the hollow ring is fixedly connected to the multiple arc-shaped uprights by bolts;

[0017] The practicality of the device is improved by connecting hollow rings to the top of multiple curved vertical plates. These hollow rings facilitate the conveying of steel strips.

[0018] In a preferred embodiment, the rotating frame further includes an inner support, which consists of a round rod and a second connecting rod. The top of the second connecting rod is fixedly connected to the round rod, and the bottom of the second connecting rod is rotatably connected to the circular seat. The round rod is located inside a plurality of arc-shaped upright plates, and the top of the round rod extends out of the hollow ring.

[0019] By setting up a round rod, which serves as an auxiliary for conveying the strip steel, the strip steel can be conveyed smoothly and efficiently. The strip steel, which is wound around the arc-shaped vertical plate, will rotate on the circular seat through the round rod, causing the strip steel to be conveyed around the round rod towards the forming machine, thereby improving the practicality of the device.

[0020] In a preferred embodiment, a guide rod is fixedly connected to the top of the hollow ring, and the guide rod is a circular column.

[0021] The guide rod provides the correct direction to ensure the precise feeding position of the strip steel during the forming process of the straight seam welded pipe, thereby improving the quality of the formed product, reducing the defect rate, and enhancing the practicality of the device.

[0022] The beneficial effects of this application are:

[0023] 1. This straight seam welded pipe forming frame, when the strip steel is conveyed to the forming machine for forming, will drive the circular seat to rotate on the circular disc, causing the strip steel in the groove to wind around the arc-shaped vertical plate. Then the strip steel wound on the arc-shaped vertical plate will rotate on the circular seat through the round rod, causing the strip steel to be conveyed around the round rod towards the forming machine. During the conveying process of the strip steel, the strip steel will be provided with the correct direction through the guide rod, so as to ensure the precise conveying position of the strip steel during the forming process of the straight seam welded pipe, improve the quality after forming, reduce the defect rate, and greatly improve the practicality of the device;

[0024] 2. In the straight seam welded pipe forming frame, the strip steel is located in the groove of the ring frame during the straight seam welded pipe forming process. One end of the strip steel is wrapped around the arc-shaped vertical plate of the outer support and then passes between two arc-shaped vertical plates, wrapping around the round rod. It is connected to the forming machine through the guide rod, which greatly improves the practicality of the device. Attached Figure Description

Each support plate 13 is fixedly connected to the annular frame 11 on the side away from the circular disc 12, and the circular disc 12 is fixedly connected to the inside of the annular frame 11 through multiple support plates 13.

[0031] The annular frame 11 has a groove 111 inside, and a strip steel 4 is placed inside the annular frame 11. By opening the groove 111 inside the annular frame 11, the strip steel 4 is located in the groove 111 of the annular frame 11 during the straight seam welded pipe forming process, which is used to store a large number of strip steel 4, thereby improving the practicality of the device.

[0032] Multiple arc-shaped support plates 14 are fixedly connected to the outside of the ring frame 11. Each arc-shaped support plate 14 is welded to the ring frame 11. By fixing multiple arc-shaped support plates 14 to the outside of the ring frame 11, the ring frame 11 is fixed, improving stability and support, thereby enhancing the practicality of the device.

[0033] The rotating frame 2 includes an outer support 21, which is composed of a circular base 211, an arc-shaped upright plate 212, and a hollow ring 213. The circular base 211 is set on the top of the circular disk 12. A first connecting rod 2111 is fixedly connected inside the circular base 211, and the bottom end of the first connecting rod 2111 is rotatably connected to the inside of the circular disk 12. By setting the first connecting rod 2111 between the circular base 211 and the circular disk 12, the relationship between the two is connected, and the rotation effect is achieved, thereby improving the practicality of the device.

[0034] Multiple arc-shaped upright plates 212 are fixedly connected to the top of the circular base 211. Each arc-shaped upright plate 212 is located at the top edge of the circular base 211, and the outer surface of each arc-shaped upright plate 212 is arc-shaped. By setting multiple arc-shaped upright plates 212 between the circular base 211 and the hollow ring 213 for winding the strip steel 4, the special shape of the arc-shaped upright plates 212 can ensure that the strip steel 4 is not easily affected and deformed, thereby improving the practicality of the device.

The round rod 221 is located inside the multiple arc-shaped vertical plates 212, and the top of the round rod 221 extends out of the hollow ring 213. By setting the round rod 221, the round rod 221 is used to assist in the conveying of the strip steel 4, so that the strip steel 4 can be conveyed smoothly and smoothly. The strip steel 4 wound on the arc-shaped vertical plate 212 will rotate on the circular seat 211 through the round rod 221, causing the strip steel 4 to be conveyed around the round rod 221 towards the forming machine, thereby improving the practicality of the device.

[0037] A guide rod 3 is fixedly connected to the top of the hollow ring 213, and the guide rod 3 is a circular column. The guide rod 3 provides the correct direction to ensure that the strip steel 4 is accurately conveyed during the forming process of the straight seam welded pipe, thereby improving the quality after forming, reducing the defect rate, and thus improving the practicality of the device.
