Fig. 2: the section enlarged diagram at C place among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing 1-2 the specific embodiment of the present utility model is made a detailed explanation.
Roll forming device on a kind of metal blade forming machine shown in Fig. 1-2 is by 7,4 groups of horizontal from left to right die mould wheels 10 of side plate, corresponding also 4 groups of hold-down devices 11 of side disposed thereon with die mould wheels 10 quantity.Die mould wheels 10 take turns 8 and constitute with the shaping cam 9 of the band arc plush copper of its coupling by the moulding of band arc groove is recessed.Adjacent die mould wheels 10 all connect all die mould wheels 10 homodromous movements of assurance by idle wheel 18, and idle wheel 18 all is between two shaping cams 9 of adjacent die mould wheels 10, and the shaping cam 9 on the low order end die mould wheels 10 connects motor by driving shaft 19.Shaping cam 9 on the low order end die mould wheels 10 is the equal of a driving wheel, other is all driven pulley, and moulding is recessed to be taken turns 8 and deviate from mutually with shaping cam 9 direction of rotation, and moulding is recessed to be taken turns 8 and be rotated counterclockwise, shaping cam 9 is to turn clockwise, and has guaranteed that the uniformity of blade outbound course promptly all moves right.
Hold-down devices 11 is arranged on the top of side plate 7, hold-down devices 11 is from top to bottom successively by adjusting gland 12, compression spring 13, suppressing plate 14, connecting rod 15, slide block 16 and adjust bolt 17 and constitute, the fixedly connected plate 14 that suppresses in connecting rod 15 upper ends, the lower end connects slide block 16, adjust bolt 17 be arranged on slide block 16 bottoms and position be in moulding recessed take turns 8 and shaping cam 9 between the junction, by adjust bolt 17 adjust moulding recessed take turns 8 and shaping cam 9 between the gap.Moulding is recessed to be taken turns 8 and is installed on the slide block 16, and shaping cam 9 is fixedly mounted on the side plate 7.Adjust the pretightning force of compression spring 13 by rotating gland 12, act on and make moulding material obtain forming force on the slide block 16 by suppressing plate 14, take turns 8 and shaping cam 9 rolls forming by moulding is recessed, adjust by adjusting bolt 17, make to be loaded on that moulding on the slide block 16 is recessed takes turns 8 and be fixed between the shaping cam 9 on the side plate 7 and keep certain clearance, guaranteed the material of roll extrusion different-thickness.
Moulding on every group of die mould wheels 10 is recessed take turns 8 and the radius of curvature of shaping cam 9 be that radian is from left to right held gradually and diminished, the radius of curvature that is every group is all inequality, the die mould wheels 10 that blade pass is crossed 4 different radians are pressed into, by the consistent accuracy standard of the blade radian of the repeatedly final formation of die mould, the good whole piece blade of firmness is difficult for flexural deformation.
The foregoing description only is a this patent embodiment preferably, for example in the die mould wheels 10 moulding recessed take turns 8 and the upper-lower position of shaping cam 9 can change.The structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection domain of this patent.
