Prefabricated smoke exhaust pipeline forming machine

Abstract

The invention discloses a prefabricated smoke exhaust pipeline forming machine. The prefabricated smoke exhaust pipeline forming machine comprises an outer template and an inner template. The outer template comprises an outer bottom template. Side templates are installed on both sides of the outer bottom template through locking devices. The outer bottom template and the templates on both sides enclose an external mould cavity which is internally provided with a plurality of inner templates which can be detached. The inner templates enclose a mandrel in the external mould cavity. A forming cavity is formed between the inner and outer templates. An end frame is arranged between the outer wall of the mandrel at each end of the forming cavity and the corresponding inner wall of the outer template. Extendable inner mould support frames corresponding to the end frames are arranged at both ends of an internal cavity of the mandrel. The openable outer template locking devices are arranged at the ends of the two side templates. According to the prefabricated smoke exhaust pipeline forming machine provided by the invention, moulds of thin wall smoke exhaust pipelines can be mechanically produced, thereby solving the problem that mechanical production is not available in the moulding field of prefabricated non-circular thin wall members. The product is formed by one step, the production efficiency is improved, the labor intensity of workers is reduced, and the product is high in strength and good in quality.

Description

technical field [0001] The invention relates to the technical field of prefabricated molding machinery for building facilities, in particular to a prefabricated exhaust gas pipe forming machine. Background technique [0002] The existing flue gas exhaust pipe has a non-circular cross-sectional inner cavity, which is basically hand-made, and the production efficiency is low. The horizontal prefabrication method is adopted, and the prefabrication site takes up a lot of space. Since the flue gas pipe wall is 10— For thin-walled pipes with a thickness of 15mm, it is difficult to keep the wall thickness of the pipes consistent during manual production, and the waste of raw materials is serious. In addition, the pipe walls are not completed at one time during manual production. The product strength is low, and the product quality is difficult to guarantee. broken. As a result, prefabricated component forming machines for producing thin-walled exhaust gas ducts appeared on the mar...

Problems solved by technology

[0002] The existing flue gas exhaust pipe has a non-circular cross-section inner cavity, which is basically handmade, and the production efficiency is low. The horizontal prefabrication method is adopted, and the prefabrication site takes up a lot of space. Since the pipe wall of the flue gas exhaust pipe is 10— For thin-walled pipes with a thickness of 15 mm, it is difficult to keep the wall thickness of the pipes consistent during manual production, and the waste of raw materials is serious. In addition, the pipe walls are not completed at one time during manual production. The product strength is low, and the product quality is difficult to guarantee. broken

As a result, prefabricated component forming machines for producing thin-walled exhaust gas ducts appeared on the market to realize mechanized mold production for exhaust gas ducts. However, the existing prefabricated component forming machines have complex structures, cumbersome disassembly and assembly of internal and external templates, and low production efficiency.
