Description

A kind of Spiral ducted unit

Technical field

The utility model belongs to pipe machining equipment technical field, and in particular to a kind of Spiral ducted unit.

Background technique

Currently, known Spiral ducted unit is all by the helically wound tubing of dribbling material volume of a fixed width, dribbling material passes through Raw material is input in holding-on machine by driving mechanism, transmission mechanism, holding-on machine curling downwards upwards respectively by the both sides of dribbling material, so Afterwards by the guidance of ring steel belt so that dribbling material crimp downwards while with upsweep while mutually fasten, then by phase up and down To the nipper wheels of rolling, the crimping mutually fastened is compressed.In existing air-cooled ducted air conditioner mid-game strip due to rolling in holding-on machine The process such as friction, bending deformation between friction and mold, it will a large amount of frictional heat and process residues are generated, on The higher surfaces externally and internally that will be bonded in pipeline of temperature for stating residue, since the duct length after most of processing is longer, pipeline Internal diameter it is smaller, cause the residue of inner surface of pipeline to be not easy to be removed, and due in holding-on machine mold work long hours, in height Under warm environment, it will the error for causing increase crimp profile after heat expansion reduces the surface hardness of mold, nipper wheels above and below reduction Surface hardness, or even the transmission shaft bending deformation for supporting nipper wheels can be made, eventually leading to the crimping mutually fastened cannot be tight Compression so that the phenomenon that leak, gas leakage occurs in the spiral duct wound, then have the high temperature generated in process that can also drop The service life of low die with edge-folded.

Solve the above problems used technical side in the utility model patent application No. is CN200920104861.9 Case is that support plate is provided with ventilation hole within the scope of ring steel belt, is located at disposed at air vent setting in the support plate other side There is blower.As it can be seen that it is after the process residues generated in production process are blown out processing from the direction far from support plate by blower Spiral duct, but there are a defects for the technical solution: with the increase of spiral duct length, blower can not blow out clast Spiral duct causes a large amount of process residues to be trapped in spiral duct far from the inner wall of support plate instead.
