Abstract

The invention discloses a circular tube end face nip machine comprising a disc and a centering fixture, wherein both of the disc and the centering fixture are arranged on a rack; the centering fixture is matched with the surface of a circular tube to be processed; the disc is arranged on one end of the rack; the disc is connected to a power device; and an inner roller mechanism and an outer roller mechanism are arranged on the disc in a manner of moving in opposition to each other in the radial direction on the surface of the disc. The nip machine is suitable for nipping circular tubes different in diameters and turnup shapes, particularly suitable for nipping the end face of a large-sized circular tube; and the machine is small in volume, low in weight, simple in structure, convenient for use and high in efficiency.

Description

technical field [0001] The invention relates to a biting device, in particular to a round tube end face biting machine. Background technique [0002] At present, the ventilation pipes of the dust removal equipment are mostly round pipes welded by thin steel plates (thickness above 3mm), and the connections are flange bolt connections. The flange must be welded first during production. In order to make the end face of the flange stick and pass through the bolts, it is necessary to weld a flange or drill a flange bolt hole. The assembly is complicated, the efficiency is low, and the cost is high. The use of galvanized iron (white iron) round pipes as ventilation pipes simplifies assembly and has the advantages of beautiful appearance, corrosion resistance, and light weight. The connection principle of galvanized iron sheet round pipe is as follows: figure 1 , the connected round pipe 1 end face needs to be flanged outwards (snapping buckle), clamped with pipe collar 18 and t...
