Inquiry has two places with the immediate prior art of the invention: (one) Japan, the patent No.: JP54006854, date of declaration 1979-01-19 by retrieval; (2) U.S., the patent No.: US6443040, date of declaration 2002-19-03; Its essence of patent of (seeing Appendix) Japan and the U.S. is the same substantially, all be on a cylinder, to be entwined with band steel (or steel plate), therefore must use special-purpose winding machinery (it is more accurate perhaps to be called the winding rolling mill), because the material that uses must be a band steel (or steel plate), so the trade mark of this steel must be the trade mark of steel board, we know have the steel of many trades mark can not rollingly become sheet material, as tool steel, bearing steel, mould steel, special alloy steel etc.Therefore in this regard, its employed steel has limitation, can not satisfy the conveying requirement to the solid material of all specific (special) requirements; In addition, owing to be to use band steel (or steel plate), the cross section of its helicallobe is a rectangle, if allow it become other shape, as trapezoidal, arc etc. are impossible;
Summary of the invention
The objective of the invention is need not the import price costliness the winding rolling mill, use existing standard equipment (also wanting corresponding increase tractor equipment and heating device certainly), produce the single-piece helicallobe.Nor operate in the engineering worker of this equipment with specialty, and only can produce with common standard equipment and staff, productive costs is lower, is easy to promote, and can produce the helicallobe of any trade mark steel and special cross-section shape.
Technical scheme: the one-piece auger blade manufacturing process of conveyor screw of the present invention, it is the round steel material that adopts any trade mark, on lathe, the round steel material is cut into screw shaped, conveyor screw is separated with the cutting of screw rod cylinder, again conveyor screw is penetrated on the standard cylinder, conveyor screw one end is fixed, and the other end is stretched to pitch by tractor and reaches governing criterion, and conveyor screw is taken out from cylinder.
The one-piece auger blade manufacturing process of described conveyor screw draws when adopting dead-soft steel or low-alloy steel at normal temperatures.
The one-piece auger blade manufacturing process of described conveyor screw draws under heated condition more than adopting medium-carbon steel or during the conveyor screw of other class alloy steel.The heating-up temperature scope is different according to the kind difference of steel, generally at 600～900 degree.
Beneficial effect: the present invention compares its beneficial effect and is undoubtedly technology and has striden major step forward with domestic present split type production method.Because the smooth smooth no weld seam of blade integral, therefore can reduce and material between resistance, raise the efficiency thereby reach, cut down the consumption of energy, reduces stable working hot-tempered.Made on the quality of conveyor screw and the technology content a big step.
The present invention compares with U.S. technology with Japan, need not use special-purpose winding rolling mill equipment (this equipment price should compare costliness), therefore also need not specialty operate in the engineering worker of this equipment, and only can produce with common standard equipment and staff, so productive costs is lower, be easy to promote.Can use the steel of any trade mark in addition in addition, produce the helicallobe that the cross section is other shape of non-rectangle, as trapezoidal, right-angled trapezium, circular arc etc., and this does not accomplish for Japan and U.S.'s technology.
