Problems solved by technology

The quality of the spiral duct produced by this stainless steel spiral duct mechanism is not good, especially the reliability of the connection of the spiral occlusal lap edge is not firm. Gradually began to appear that the occlusal edge is not embedded in the bottom, the occlusal seam is sloppy, and the shape of the air duct is abnormal, etc., and it is getting more and more serious

Abstract

The invention relates to a two-way active rolling type stainless-steel spiral air pipe machine. The two-way active rolling type stainless-steel spiral air pipe machine comprises a rack, a traction jaw, an upper pressing plate, a lower pressing plate, a fixing band mold and a rolling device, wherein the rolling device comprises a lower roller and an upper pressing roller. By virtue of the two-way active rolling type stainless-steel spiral air pipe machine, the passive friction driving between the upper pressing roller and a stainless-steel band is changed into the direct transmission of a speed reducer through a chain transmission mechanism so as to form a pure rolling pressing gap meshing state between the upper pressing roller and the upper surface of the stainless-steel band and between the lower roller and the lower surface of the stainless-steel band, and the phenomenon of slipping caused by the passive friction between the upper pressing roller and the stainless-steel band is avoided; meanwhile, hatching knurling is additionally performed on the outer cylindrical surface of the upper pressing roller, and the friction coefficient between the upper pressing roller and the stainless-steel band is increased, so that the phenomenon of breaking of meshed gap edges between inner and outer lapping edges caused by allowance slipping is eliminated. The two-way active rolling type stainless-steel spiral air pipe machine has the advantages of precise design, reasonable structure, tightness and firmness of pressing gaps, and high air pipe quality.

Description

technical field [0001] The invention relates to a spiral air duct machine, in particular to a spiral air duct machine which rolls a stainless steel strip material into a thin-walled pipe with a spiral seam, and belongs to the technical field of mechanical sheet metal. Background technique [0002] Stainless steel spiral ducts are usually made of SUS series strip materials. Due to the poor plasticity and tensile properties of SUS materials, which are not as good as galvanized iron strips, the manufacturing process of spiral air ducts is complicated and the manufacturing quality is difficult to guarantee. The existing stainless steel spiral air duct uses multiple sets of pulling jaws on the spiral air duct machine. On the one hand, the two sides of the SUS stainless steel belt are bent into occlusal edges, on the other hand, the stainless steel belt is pulled forward, and through the The fixed belt mold and rolling device that pulls the back of the jaw and has a set angle wit...
