Abstract
The utility model provides a directly-coupled slantingly-conveying roller for a Accu-Roll tube rolling set, which is applied in heat rolling seamless steel pipe production line of metallurgy machinery industry. In the utility mode, both a reverser and an auxiliary spline in conventional equipment are removed, a middle deceleration device is omitted, a combined type reducing motor is used for directly driving a universal coupling to be coupled with the slantingly-conveying roller, the included angle formed by the slantingly-conveying roller and a rolling center line is 40 degrees to 50 degrees, and the inclined included angle formed by the universal coupling and the slantingly-conveying roller is larger than 0 degree but smaller than 10 degrees. The slantingly-conveying roller has a simple structure and is low in reformation cost, avoids components prone to be in failure, not only maintains the pre-rotation function, but also improves the capillary forwarding force, realizes the purpose of reducing the misroll, improving the yield and decreasing the failure rate, and improves the work environment of the main equipment.
Description
[technical field]
The utility model relates to metallurgical machinery sector Accu-Roll tube rolling unit associated mode and tiltedly send roller.
[technical background]
The Accu-Roll pipe mill is the nucleus equipment on the hot rolled seamless steel tube production line, and as the ultimate unit of oblique milling mode, its portable station for the subsidiary engine part requires to finish hollow billet and axially carries, satisfy the rolling rotation initial velocity of oblique milling rotation again, after hollow billet is nipped, disengage with hollow billet immediately.
Portable station at present at home on the oblique milling line usually employing tiltedly send roller class, charging basket class, pinch roll and tiltedly send roller composite class, pinch roll and three rollers to embrace the center device class.
Tiltedly send roller class portable station owing to performance requirement and on-the-spot narrow spatial constraints, complex structure, compactness, maintainability is poor; Bevel Gear Transmission is often beaten tooth, and some bassoon also occurs, thick pipe is sent difficulty to.
Charging basket class portable station cost is relatively cheap, but collide between charging basket, and need smear dry oil lubrication to the whole rail slide plate, because the iron scale problem of heating hollow billet, on-the-spot rolling condition is more abominable, because hollow billet is sent into before the milling train not pre-rotation, the hollow billet quality there is very big influence in addition.
Pinch roll and tiltedly send roller composite class portable station because hollow billet appearance after the perforation and irregularity are pointed out tail etc. frankly except bending has spiral in addition, pinch roll causing useless pipe in case clamp and at the concave-convex surface place hollow billet is stopped the rotation on the contrary and advance.
It all is driven rolls that pinch roll and three rollers are embraced center device class portable station roller, can't wear large-scale unit (more than φ 114 units) with plug circulation in advance having plug, mainly is applicable to rolling small dimension steel pipe.
Since last century, the nineties Accu-Roll tube rolling unit was born, above-mentioned drawback was design of puzzlement equipment and maintenance management personnel's a a great problem always.
[summary of the invention]
The purpose of this utility model is at above drawback, the improved Accu-Roll tube rolling unit associated mode that provides a kind of reliability, economy to have both tiltedly send roller, this associated mode send tiltedly that roll structure is simple, improvement cost is little, the parts that saved easy generation fault, both kept the pre-rotation function, improved hollow billet again and moved ahead and send power to, thus realize reducing roll useless, improve output and reduce the purpose of rate of breakdown, and improved the working environment of main equipment.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is as follows:
A kind of Accu-Roll tube rolling unit associated mode tiltedly send roller, mainly comprise and tiltedly send roller, Hooks coupling universal coupling, its improvements are: the combined type reducing motor directly drives Hooks coupling universal coupling and tiltedly send roller to link, and the angle that tiltedly send roller and rolling centerline is 40 ° of-50 ° of angles; Original technical commutator and auxiliary spline thereof have been cancelled.
Adopt above technical scheme, when the angle that tiltedly send roller and rolling centerline during near 45 °, the angle between combined type reducing motor and the roller can satisfy the use needs of common universal-joint spindle.Consider tiltedly to send roller adjustable height 103mm, then at the combined type reducing motor and tiltedly send and select Hooks coupling universal coupling between roller, Hooks coupling universal coupling and tiltedly send slanted angle between the roller greater than 0 ° less than 10 °.
Motor directly drives Hooks coupling universal coupling and tiltedly send roller to link, and the trouble points such as having saved original technical commutator and auxiliary spline thereof that directly links keeps the pre-rotation function, has increased the angle that tiltedly send roller and roll line again, has improved hollow billet and has moved ahead and send power to.
The hollow billet that tiltedly send roller only need reach 780N.m and 105.39r/min carries pace to get final product, so omit the intermediate reduction gear device, selects the combined type reducing motor for use, has improved the working environment of main equipment, keeps not influencing the operating position of existing plug return roller table.
[description of drawings]
Shown in the drawings is the utility model structural profile schematic diagram.
[specific embodiment]
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Accu-Roll tube rolling unit associated mode shown in the drawings tiltedly send roller, by bearing (1), tiltedly send roller (2), screw (3), Hooks coupling universal coupling (4), combined type reducing motor (5), motor base (6) to constitute.Tiltedly sending roller (2) and rolling centerline angle is 45 °.The motor model that combined type reducing motor (5) is selected for use is DSZYPCJ200-15-189-B3-I, rated power: 15KW, specified output speed: 189r/min, frequency range 3-100HZ (3-50HZ speed regulation by constant torque, 50-100HZ constant-power speed regulation).Hooks coupling universal coupling (4) and tiltedly to send the slanted angle between the roller (2) be 2.5825 °.
Claims (3)
1. an Accu-Roll tube rolling unit associated mode tiltedly send roller, mainly comprise bearing (1), tiltedly send roller (2), screw (3), Hooks coupling universal coupling (4), its improvements are: combined type reducing motor (5) directly drives Hooks coupling universal coupling (4) and tiltedly send roller (2) to link.
2. a kind of Accu-Roll tube rolling unit associated mode according to claim 1 tiltedly send roller, it is characterized in that, tiltedly sending the roller (2) and the angle of rolling centerline is 40 °-50 °.
3. a kind of Accu-Roll tube rolling unit associated mode according to claim 1 tiltedly send roller, it is characterized in that, Hooks coupling universal coupling (4) and tiltedly send slanted angle between the roller (2) greater than 0 ° less than 10 °.
