Description

Technical Field

[0001] The utility model relates to the technical field of malleable cast iron, in particular to equipment for processing external threads of malleable cast iron pipe fittings. Background Art

[0002] Malleable cast iron is made of molten iron with a certain chemical composition, which is cast into a white blank and then annealed. It has high strength, plasticity and impact toughness and can partially replace carbon steel. Malleable cast iron is often used in the production of pipe fittings. When processing malleable cast iron pipe fittings, they need to be threaded. Therefore, a device for processing the thread of malleable cast iron pipe fittings is needed.

[0003] When operators perform external threading work on malleable cast iron pipe fittings, they often use corresponding malleable cast iron pipe fitting external threading equipment. Although the existing equipment can achieve the purpose of external threading, waste slag will be generated during actual use. The waste slag will fall onto the processing table. If it is not cleaned up in time, it may cause accumulation, causing trouble for manual cleaning. In addition, the diameters of malleable cast iron pipe fittings are different, and the clamping and fixing mechanisms are mostly fixed modes, which cannot meet the requirements of clamping and fixing malleable cast iron pipe fittings of different diameters, and the practicality is reduced.
