Description

Technical Field

[0001] The utility model relates to the technical field of concentricity correction, in particular to a pipe mold concentricity correction device. Background Art

[0002] The pipe mold is a device used to produce metal water-cooled ductile iron pipes of different sizes. It belongs to the field of mechanical engineering. The pipe mold is also called metal water-cooled ductile iron pipe mold. It is mainly used for the production of ductile iron pipelines. After two sets of annular pole pipe molds are connected, the connection needs to be tested for concentricity to prevent the concentricity from being offset at a large angle, causing the pole to bend or deform. The existing detection and correction work generally uses a ruler to measure first, and then loosens the connecting bolts of the two sets of annular pole pipe molds and adjusts them.

[0003] Existing technologies, such as: CN215472012U, a concentricity correction device for annular pole tube molds, can detect the connection concentricity of two sets of pole tube molds through the coordinated use of a shell, a mounting rod, a meter wheel, a spirit level and a display screen. Compared with the use of a ruler for measurement and detection, it effectively improves the detection efficiency and operation convenience, thereby paving the way for the next step of rapid correction and relatively improving the practicality of the device.

[0004] However, the device still has certain shortcomings during use. The pipe mold cannot be stably clamped and supported by the semicircular plate, which affects the concentricity value and correction operation measured by the meter wheel and the spirit level. After the semicircular plate of the device is stuck on the surface of the pipe mold, it is not convenient to adjust, which affects the work efficiency. At the same time, manually turning the handle affects the correction efficiency. Utility Model Content
