Abstract

The invention belongs to the field of mechanical automation, overcomes the defects of the prior art, and provides a novel and high-efficiency processing method and a novel and high-efficiency processing device for automatically filling fire retardant core materials in a fire retardant ring. The novel device for filling fire retardant ring core comprises a conveying device, a material automatic control system and an automatic control pneumatic press, wherein the automatic control pneumatic press comprises an automatic control flattening pneumatic press, an automatic control punching pneumatic press and an automatic control rammed expansion pneumatic press arranged in turn; and a material displacement monitoring device is arranged below the material automatic control system. Due to ingenious design and matching of various components, the fire retardant ring is automatically produced, and the production efficiency and product quality are improved. Moreover, the device is wide in application range and can produce products with various inner diameter dimensions. Compared with the conventional manual production, the invention has prominent substantial progress and characteristics.

Description

technical field [0001] The invention belongs to the field of mechanical automation, and in particular relates to a novel method and device for automatically filling a core body of a fire retardant ring. Background technique [0002] Due to the superior corrosion resistance of plastics, hard polyvinyl chloride pipes have been widely used in the construction industry to replace traditional metal pipes as drainage pipes. Its advantages are low price, convenient construction and long service life. But it has a fatal shortcoming, that is, it is easy to melt. Once a fire breaks out, the fire can easily spread along the hard PVC pipe, which poses a great safety hazard. For this reason, people design a kind of fire-stop ring, and this fire-stop ring is generally made up of metal shell and the expansion fire-stop core material that is contained in the shell. The fire retardant ring is placed on the connection between the hard polyvinyl chloride pipe and the floor or partition wall....
