Since in production process, the impurity such as iron filings of metal-sheet edges often enter 11 gap of bearing, annular
In rolling groove 4, the movement of bearing 11 or ball 12 is hindered, is useful for removing crimping for this purpose, being detachably connected on U-shaped folder head 3
The cleaning device of impurity on wheel 1.Above-mentioned cleaning device includes a magnetic stripe 13 being arranged on 3 madial wall of U-shaped folder head（Referring to Fig. 3）, on
Magnetic stripe 13 is stated for absorbing the impurity such as the iron filings that may be adhered on crimping wheel 1, above-mentioned impurity is avoided to enter bearing 11 or ring
The movement of ball 12 is caused to hinder in shape rolling groove 4.
The working principle and beneficial effect of the utility model is as follows：
The fitting being set between 3 side wall of 1 side wall of crimping wheel and U-shaped folder head can reduce crimping wheel 1 and clamping part it
Between frictional force, the increased friction for avoiding the deformation due to crimping wheel 1 from causing it between clamping part, so that crimping wheel 1
It is more uniformly effective to the winding at sheet metal edge, promote the quality of crimping.Due to the meeting after working long hours of crimping wheel 1
Fever thermally expands 7 expanded by heating of part using this characteristic, abuts block 6 and ball 12 is pushed to move, increase crimping wheel 1 and clamping part
Between gap, the friction for both helping to further decrease ensures the normal rotation of crimping wheel 1.
As shown in fig. 6, being based on above-mentioned ventilating duct oral area hemming device, the utility model also proposed a kind of ventilating duct oral area
Crimping machine, similarly to the prior art, including board 14 is provided with branch on board 14 to agent structure perpendicular to 14 surface pivots of board
Axis 15, the one end of fulcrum 15 are detachably provided with convex and fix disk 16, be also connected on board 14 and be provided with the fixed disk turn of driving
Dynamic driving device.Above-mentioned driving device uses motor and driving belt 18,18 band of driving belt in the utility model
Dynamic fulcrum 15 rotates.Disk 16 is fixed on board 14 close to convex to be additionally provided with such as preceding ventilating duct oral area hemming device, ventilating duct
The supporting rod 2 of oral area hemming device is pushed by hydraulic cylinder 17 so that crimping wheel 1 can be bonded the edge for squeezing metallic plate, complete
At crimping.
The course of work of above-mentioned crimping machine is as follows：
When the setting of the ventilating duct of crimping, when convex is fixed on disk 16, convex fixes the rotation of disk 16 and ventilating duct is driven to turn
Dynamic, for ventilating duct oral area hemming device under the promotion of hydraulic cylinder 17, crimping wheel 1 abuts extruding with metal-sheet edges so that gold
The edge for belonging to plate deforms winding, is achieved in the crimping of ventilating duct.In the process, between crimping wheel 1 and U-shaped folder head 3
The probability that sliding friction occurs substantially reduces, and thereby guarantees that the effect of crimping.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
