Technological Innovation: A seamless steel pipe feeding frame

On June 28, 2025, financial news reported that the National Intellectual Property Administration announced that Shandong Chunxiao Steel Pipe Manufacturing Co., Ltd. has obtained a patent for "A Seamless Steel Pipe Feeding Frame" (Authorization announcement number CN223032189U), which was filed in August 2024.

The patent abstract indicates that this utility model belongs to the technical field of steel pipe feeding. A regulating limit component is provided below the main body of the feeding frame, and lifting and stabilizing components are provided at both ends below it.

The limit adjustment assembly includes a fixed plate, with springs installed at both ends on the top. The top of the springs is connected to a limit frame, and the middle part of the lower surface of the limit frame is fixedly connected to a fixed block. A handle is installed at the bottom, and a fixed rod is embedded inside.

This design, by adjusting the limit component, allows for the selection of whether to limit as needed, preventing the seamless steel pipe from shifting and enhancing its practicality. Relying on the lifting and stabilizing component, the main roller can be quickly lifted off the ground, with simple operation and enhanced working stability.

Its technical background and inventions are as follows:

Background technology

Seamless steel pipes are made by piercing a single round steel pipe and have no weld seams on the surface. When feeding seamless steel pipes, a feeding frame is required.

However, during the operation of the existing feeding frame, no structure is set to limit the seamless steel pipes. As a result, the seamless steel pipes are prone to positional deviation during the feeding process, which affects subsequent processing.

Technological invention

The purpose of this new utility model invention patent is to provide a seamless steel pipe feeding frame to solve the problem proposed in the background technology that no structure is set to limit the seamless steel pipe. For details, please refer to the following picture
