Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing, and in particular to a pipe flattening device. Background Technology
[0002] Metal pipes, also known as steel pipes, are used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, and are also an economical steel material. The development of the chemical industry, as well as the drilling and transportation of oil and natural gas, has strongly promoted the development of the steel pipe industry in terms of variety, output, and quality. Steel pipes can be divided into two main categories according to their production methods: seamless steel pipes and welded steel pipes. They can be used in various industries for liquid and gas pressure pipelines, gas pipelines, water pipelines, gas pipelines, heating pipelines, electrical conduits, etc.
[0003] To meet the diverse needs of various industries for steel pipes, flattening is necessary. A steel pipe flattening device is a machine used to flatten steel pipes. Existing flattening devices typically use conveyor rollers to transport the steel pipe to a specific position, then use cylinders or hydraulic cylinders to push a pressure block downwards, flattening and shaping the steel pipe on the resting surface. However, since most factories produce steel pipes of fixed sizes, the corresponding flattening devices are often only compatible with those pipe sizes, making them unsuitable for different sizes. Even if the conveyor rollers can be adjusted, the disassembly process is complex, wasting manpower and causing production line downtime. Therefore, some companies have adopted a solution of not adjusting the conveyor rollers to maintain continuous production line operation. This results in the displacement of small-sized steel pipes during transport or jamming of large-sized steel pipes, ultimately affecting product quality. Utility Model Content
