The specific embodiment
Accompanying drawing discloses the structural representation of a preferred embodiment involved in the present invention without limitation, explains technical scheme of the present invention below with reference to accompanying drawing.
As shown in Figure 3, be drilled with technique for fixing hole 31 and drawing process hole 32 on the helical blade blank 30 waiting to draw.
As depicted in figs. 1 and 2, a kind of helical blade drawing device of the present invention, comprise frame, mandrel, the support plate 41 that described frame 4 comprises base plate 42 and fixedlys connected with base plate, described mandrel 8 is vertically mounted on a side of support plate 41, described drawing power set are positioned at mandrel 8 the same sides, and described drawing power set external part is provided with the blade stretching installation portion, and described support plate 41 1 sides that are positioned at mandrel 8 bottoms are provided with the vanes fixed installation portion.Specifically, described drawing power set are Electrohydraulic push rod 1.Described Electrohydraulic push rod 1 is fixed on the support 2.Described support 2 usefulness bolting are on pedestal.
Described blade stretching installation portion comprises joint 9, screw 6 and associated nut 7, described joint 9 one ends link to each other with Electrohydraulic push rod 1 external part, the other end is provided with groove, and screw 6 passes groove and waits that drawing helical blade blank 30 drawing process holes links to each other with nut 7.
Described vanes fixed installation portion comprises screw 6 and the associated nut 7 that passes support plate 41 circle open-works and wait to draw helical blade blank 30 technique for fixing holes 31.
Described base plate 42 is the flat board that is provided with anchor bolt installation hole of a horizontal positioned, and described support plate 41 vertically is installed on the base plate 42.
Described mandrel 8 one sides are provided with the back-up ring 5 that prevents the mandrel axial float, and described back-up ring 5 is fixedly mounted on the support plate 41.
The diameter of mandrel 8 should be than the little 2～5mm of helical blade 3 diameter of bores, helical blade 3 external diameter differences, and its diameter of bore is also different, when drawing various outer diameter helical blade 3, the mandrel 8 of replaceable different-diameter.When drawing than major diameter helical blade 3 in addition, required pulling force is also big, at this moment just Electrohydraulic push rod 1 pulling force can be transferred big or select specifiedly to push away greatly, the Electrohydraulic push rod of pulling force.
During installation, base plate 42 horizontal positioned, support plate 41 vertically is fixedly mounted on the middle part of base plate 42, can weld between base plate 42 and the support plate 41, also can be integrally formed by casting, on support plate 41, be provided with the round open-work that matches with mandrel 8, for preventing mandrel 8 axial floats, back-up ring 5 is inserted in mandrel 8, is fixed on the support plate 41 with back-up ring 5.The anchor bolt installation hole that foundation bolt passes base plate 42 fixes frame 4 on the ground.
Described drawing power set can adopt Electrohydraulic push rod, also can adopt electric pushrod.Electrohydraulic push rod is power source with the motor, by motor just (instead) make hydraulic oil pass through the double-direction gearpump pressure oil output to rotation, through the oil circuit integrated package, deliver to operating cylinder, realize the reciprocating motion of piston rod.Electrohydraulic push rod has auto-lock function, has designed pressure self-locking mechanism in the oil circuit integrated package of Electrohydraulic push rod, and motor stops operating, and piston rod rests on certain position immediately, and pressure oil is in packing state; Electrohydraulic push rod can starting under load, and electric pushrod is then very difficult; Same Electrohydraulic push rod its specified push away, in the weight range, but its push away, the pulling force step-less adjustment, thereby have the wide characteristics of driving force scope, electric pushrod then can't be accomplished; Electrohydraulic push rod can carry out stepless stroke adjustment according to customer requirements in specified stroke range, thereby realizes drawing the purpose of different pitch helical blades; Electrohydraulic push rod adopts all-hydraulic transmission, is active in one's movements, and operates steadily, and can effectively slow down external impulsive force, and Stroke Control is accurate, and electric pushrod then can not be accomplished; Electrohydraulic push rod adopts mechanical, electrical, liquid integrated full-closed structure, and working oil path is circulated in not to be had in the sealing steel cylinder of pressing, and volume is little, oil-proof, is convenient to installation and maintenance.As preferably, the present invention adopts Electrohydraulic push rod.The existing specialized factory of Electrohydraulic push rod produces, and can directly buy needed model and specification.
The course of work of Electrohydraulic push rod stretching blade is such: will wait to draw helical blade blank 30 and be inserted in mandrel 8, its technique for fixing hole 31 is installed on the vanes fixed installation portion of support plate 41, be about to the circle open-work centering on technique for fixing hole 31 and the support plate 41, with screw 6, nut 7 connects with the location, wait that the drawing process hole 32 that draws helical blade 30 then is installed on the blade stretching installation portion of Electrohydraulic push rod 1 external part, being about to wait to draw helical blade 30 1 ends inserts in joint 9 grooves, round open-work centering on drawing process hole 32 and the groove is used screw 6 then equally, nut 7 connects with the location.After preparation is carried out, Electrohydraulic push rod is switched on, motor is rotated in the forward, make hydraulic oil pass through the double-direction gearpump pressure oil output, through the oil circuit integrated package, deliver to operating cylinder, thereby give piston rod power, piston rod is waited to draw helical blade 30 by the drive of blade stretching installation portion and is outwards moved, and is drawn into rotation direction and the satisfactory helical blade 3 of pitch thereby will wait to draw helical blade blank 30.
The present invention draws power set, has reduced working strength of workers, has improved operating efficiency; By regulating the pulling force size and changing mandrel, can draw helical blade from diameter 150mm to 500mm; By in specified stroke range, carrying out stroke adjustment, can draw the helical blade of different pitch sizes, thereby reach the purpose of a tractor serves several purposes.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the invention.
