Description
Technical field
The present invention relates to power takeoff driving shaft, relate in particular to a kind of power takeoff driving shaft Cold Precision Forging Process of Spur.
Background technology
Power takeoff english abbreviation is PTO, it is exactly one group of change-speed gearing, claim again power take off, being generally to be formed by gear-box, Combined clutch, using gear to be connected with gearbox, is that axle is connected with lifting pump, it is an independent gear in gearbox, hang up this shelves, an open out, lifting pump just can turn round. Lifting pump is a hydraulic means, and lifting railway carriage, realizes self-unloading function. The special-purpose vehicle that dumper, fire fighting truck, concrete mixer, refrigeration etc. need extra power, obtains by power takeoff, and power takeoff is the attachment device that is contained in gearbox outside, and it obtains power from certain gear of gearbox. Being switched on or switched off of this power is that a magnetic valve by driver's cabin is controlled. Drive high-pressure oil pump for dumper by power takeoff; Drive water pump for fire fighting truck; Drive compressor for refrigeration car; Drive hydraulic motor Stirring tank. Power takeoff is generally connection for transmission axle or is directly connected with gear pump, is generally to connect power transmission shaft at home, and few people's design directly connects with gear pump, in Europe, North America, because the design of power takeoff is various, of a great variety. A kind of power takeoff driving shaft, comprises hollow shaft body, has inner circle and cylindrical, and described inner circle has the spline inner headed face 1, the internal diameter that connect successively and shrinks transition face 2, contraction inner headed face 3, internal diameter expansion transition face 4, expansion inner headed face 5 and large aperture inner headed face 6; Described cylindrical has the periphery 7, the external diameter that connect successively and shrinks transition face 8, contraction periphery 9, annular lug 10, straight-tooth periphery 11, the second periphery 12 and external diameter contraction flank 13. Adopt machine-tooled method to produce and have advantages of that precision is high, but its production cycle is long, manufacturing cost is high. First manufacturing firm all adopts precision forging blank technology both at home and abroad at present, then a little machined, can meet like this required precision, has reduced again manufacturing cost and cycle, also meets the trend of world today's development of manufacturing simultaneously. But because the external diameter of periphery 7 and annular lug 10 is large, shrink periphery 9 internal diameters little, belong to the little shape in large centre, two, increased difficulty to the forging demoulding. The production method that power takeoff driving shaft hot forging is traditional: blanking, heating, forge hot, normalizing, lathe processing, drilling machine bore mesopore (two boring), bore hole. China Intellectual Property Office discloses the quick precise extrusion new technology of CN1672863 axle tube forging, it is characterized in that adopting hot rolling round bar be heated to forging temperature on hydraulic press without setting up separately punching the wad operation Huo Qie Head operation, accurate quick penetrating endoporus and the outline of being shaped, technical process is: jumping-up-punching-perforation and forward extrusion-upsetting squeeze. China Intellectual Property Office also discloses CN101602157 and discloses a kind of production technology of speed reducer output shaft, comprises the following steps: a, buy raw material; B, blanking; C, be heated to 1120-1200 DEG C; D, the raw material that step c is heated pull out on pneumatic hammer swage block, and round as a ball on movable swage block, shaping forge the cylinder that substantially meets speed reducer output shaft size in loose tool; E, the base in steps d is put into jumping-up major part on friction press, enclosed closed die forging, forges output shaft forged piece; F, utilize remnant forging thermal quenching; G, 520-660 DEG C tempering; H, machine tooling; I, finished product. Power takeoff driving shaft hot forging shortcoming: tissue looseness, density is low; Intensity is low, and labour intensity is large; Efficiency is low, and the production cycle is long; Deep hole machining difficulty cost is high; Machining apparatus has high input; Waste raw material.
