Description
Technical field
The present invention relates to a kind of processing method and special equipment of helical blade, relate in particular to and a kind of steel band is adopted cold extrusion processing, make it to be configured as the processing method and the special equipment of helical blade.
Background technology
At many grain processing equipments, on conveying worm, stump extractor, wheat turner, flat spin unloader, all to use a large amount of helical blades.In the past, when these parts of production and processing, adopted such technology: at first downcut the disk that certain diameter is arranged, cut out a circular hole at the disk centre punch then, make it to become an annulus from whole steel plate; On ring, cut out a breach or joint-cutting again; Stretch vertically above-mentioned, make it to become spirality, at last some such parts are welded as helical blade.The shortcoming of this method is significantly, at first from the material consumption angle, can cause the waste of lot of materials, has about 1/2 material to become leftover bits, and when especially some occasions used valuable alloy material such as stainless steel, its processing cost was higher.Simultaneously, owing to adopt welding processing, the precision of the helical blade that this method makes is low, production efficiency is low, personnel labor intensity is big.
Summary of the invention
The invention provides a kind of processing method and special equipment that uses banded plate through the helical blade of cold extrusion, traction moulding.
Processing method of the present invention may further comprise the steps:
1), adopts steel band, band steel or plate is cut into band shape;
2), banded plate is carried out plane extruding by at least one pair of tapered rollers, the deep camber position thickness of curved workpieces is less than small curve position thickness after the crimp;
3), the traction of the workpiece after will being out of shape coiling is a spiral;
4), spiral is taken out from the axis of traction, make.
Described extruding is cold extrusion.
Special equipment of the present invention comprises tapered rollers extruder and traction coiling machine, the outlet of tapered rollers extruder and the corresponding setting of inlet of drawing the coiling machine; Described tapered rollers extruder is made up of frame, at least one pair of tapered rollers and drive unit, and the tapering of tapered rollers is 1 ~ 15 degree, and two tapered rollers are provided with in the same way, and axis is 1 ~ 10 degree angle, and gap, roller major part place is little, and drive unit connects roller; Described traction coiling machine by frame, rotating shaft, all be located at three circumferential carry-over pinch rolls of rotating shaft and drive unit and form, carry-over pinch rolls are provided with V-shaped groove, the axis of three carry-over pinch rolls is parallel to rotating shaft, puts in height equidistant each other, and rotating shaft is opposite with the direction of rotation of three carry-over pinch rolls.
The carry-over pinch rolls key of traction coiling machine is connected on the traction rollers, also is connected with the axial adjustment fixture between carry-over pinch rolls and the axle.
Banded plate is subjected to one group of roll that has certain taper to prick pressure among the present invention, because the tapered rollers that is provided with in opposite directions among the present invention is fallen at an angle mutually, promptly bundle pressure in major part place is big, and it is little that the microcephaly locates to prick pressure; Major part place linear velocity is fast, and it is little that the microcephaly locates linear velocity, and the distortion on banded plate both sides is inhomogeneous, has produced bending, and then forces traction by the traction winding equipment, has both obtained the helical blade of required form.
The present invention adopts steel band or band steel to form through cold extrusion and traction coiling, save and used multiple working procedures such as whole the disk cutting, punching system ring, stretching, welding in the Sheet Metal Processing, saved process time greatly, improved efficient, reduced labour intensity, and the precision height of product.

The specific embodiment
Processing method of the present invention may further comprise the steps:
1), can directly adopt width to meet steel band, the band steel of helical blade width requirement, perhaps plate is cut into the band shape 3 that meets the helical blade width requirement;
2), banded plate 3 or steel band, band steel are carried out the plane cold extrusion by at least three pairs of tapered rollers 2, tapered rollers 2 each other at an angle, gap, major part place is little, so to prick pressure big at the major part place, it is little that the microcephaly locates to prick pressure; Major part place linear velocity is fast, and it is little that the microcephaly locates linear velocity, and the distortion on banded plate 3 both sides is inhomogeneous, has produced bending, and the deep camber position thickness of the banded plate 1 after the crimp is less than small curve position thickness;
3), the 1 traction coiling of the banded plate after will being out of shape is a spiral; Banded plate after the flexural deformation 1 is inserted in the V-shaped groove of bottom carry-over pinch rolls 4, and carry-over pinch rolls 4 meetings of rotation drive banded plate 1 motion after the flexural deformation, through behind the carry-over pinch rolls 4 of other two height, around the spiral-shaped helical blade 6 of rotating shaft 5 formation;
4), from traction rotating shaft 5, helical blade 6 is taken out, promptly make helical blade 6 of the present invention.
