Description
[technical field]
The utility model relates to a kind of rolling metal machinery that is commonly called as milling train, the three-roller Y shaped milling train of particularly a kind of patrilineal line of descent with only one son in each generation moving axis.
[background technology]
Existing 120 ° of three-roller Y shaped milling trains claim the KOCKS milling train abroad, and it has two types:
A kind of is 120 ° of three-roller Y shaped milling trains of single-driven input shaft, please referring to Fig. 1, Fig. 2 and Fig. 3, this milling train just emerged as far back as nineteen forty-seven, be used for seamless steel pipe and welded tube stretch reducing unit and rod more, wire rod is fixed, on the tube reducing unit, label 1 ' represent bearing wherein, label 2 ' represent driving shaft, label 3 ' represent bevel gear, label 4 ' represent roll, label 5 ' represent driven axle, its feature is: driving shaft 2 ' 120 ° of three-roll racks of input, rotate synchronously by two pairs of bevel gears 3 ' 120 ° of three rolls of driving, and realize that three direction compressions are the three-dimensional calendering to metal bar.The advantage of this milling train is that transmission mechanism is simple, easy to manufacture, in light weight, cost is low.Abroad still adopt in a large number at present, domesticly be used in cable factory's copper, aluminum steel is cold rolling more.The outstanding defective of this milling train be two pairs of bevel gear 3 ' dummy rolls 4 ', owing to be subjected to the restriction of bevel gear engagement, three rolls 4 on production line ' can not radially depress adjustment, after three roll 4 ' hole slots wore and tore in the production, workpiece measurement can't recover the hole slot size after becoming greatly, have to often change whole three-roller head, cause the service efficiency of milling train low, production operational availability is low, and the product precision is low.
Second kind is 120 ° of three-roller Y shaped milling trains of three transmission power shafts, please referring to Fig. 4 and Fig. 5, wherein label 1 " represents bearing; label 2 " is represented driving shaft, label 3 " is represented bevel gear; label 4 " is represented roll, label 5 " is represented cylindrical gear driving system; label 6 " and represented shaft coupling, label 7, and " represent initiatively moving gear, label 8 " is represented upper transfer gear, label 9 " is represented lower transmissioning gear; label 10 " and is represented three-roll rack, and this three-roller Y shaped milling train outstanding feature is that 120 ° of three rolls can radially be depressed or promote and reach 10mm, changes the size of rolled piece at any time and improve dimensional accuracy on production line; Behind the roll wear, can depress, recover workpiece measurement by online adjustment roll.Therefore, this three-roller head life cycle is long, can boost productivity greatly.Its transport characteristics is that two pairs of bevel gears are moved on to outside the three-roller head in the three-roller head, links by Third Mate's Hooks coupling universal coupling and three roll spindle noses again, and consequently, 120 ° of three rolls are radially depressed the restriction that can not be subjected to bevel gear.In order to solve the synchronous rotation of 120 ° of three power transmission shafts, adopted complicated gear train, see shown in Figure 4ly, produce huge, complicated, the heavy adjustable three-roller Y shaped milling train of novel three transmission power shafts according to Fig. 4 schematic diagram of mechanism, see shown in Figure 5.
Comparison diagram 3 and two types of 120 ° of three-high mills of Fig. 5, be not difficult to find out the gap between them: a kind of be simple in structure, in light weight, cost is low, inefficient three-roller Y shaped milling train.The back is a kind of to be the three-high mill that the drive mechanism complexity is huge, heavy, cost is high, efficient is high, roller footpath φ 250 to φ 370, the tandem rolling unit of 3 frame to 5 frames, the price of KOCKS company is 3,500,000 to 6,000,000 dollars, very expensive, so a large amount of cable factories of China production of copper, aluminum steel are still used the nonadjustable three-roller Y shaped milling train of patrilineal line of descent with only one son in each generation moving axis so far.
