Abstract
A 3-roller tube rolling mill is composed of a base, a closed machine frame with hydraulic push-pull and locking unit and lubricating tube, a motor, three roller units, three roller drive and balance regulators an electric controller.
Description
Technical field
The invention belongs to seamless steel pipe production, be specifically related to produce the three-roll pipe mill of seamless steel pipe.
Background technology
At present, the three roll pipe unit is one of leading equipment in the seamless steel pipe production.The traditional structure of three-roll pipe mill is: roll is installed in the rotary drum, can realize the different roll off angles and the stepless adjustment of feed angle, roll change behind the loam cake Unscrew of frame, and the kind of drive is a separate unit master motor central driving.A complete set of equipment of introducing as domestic certain factory, and domestic newly-built a few cover three roll pipe units of later stage, except that the kind of drive of part milling train is changed into 3 motors drive separately by a motor centralized driving, other structure is not all carried out big change.
Novel three roll pipe technology is the novel Bar Rolling Process that the eighties of last century the nineties is grown up, and compares with other type equipment, and its advantage mainly contains:
(1) steel pipe of producing is the dimensional accuracy height aspect external diameter and wall thickness, particularly compares with other various production technology of steel tube, and wall thickness accuracy is very high.
(2) deformation condition is more favourable when heavy wall, middle heavy wall pipe thin-wall steel tube.
(3) quality is good, and concerning some had critical heat deformation performance steel grade, deformation condition was more favourable, has higher efficient and economy.
(4) investment is cheap, the investment of three roll pipe unit only be equal specification continuous rolling-tube unit invest 1/5th to sixth.
But three-roll pipe mill has also exposed some defectives in the utilization process, mainly contain:
(1) the adjustment link of equipment is more, is easy to produce some equipment faults or defective.And online adjustment influences the production time, and the effective operation rate that improves equipment is lower;
(2) the equipment rigidity of open top roll housing is on the low side, and the dimensional accuracy and the surface quality that influence hollow forging are beneficial to the rolling thin-wall pipe;
(3) because the feature of three-roll rolling deformed area metal stress has determined to occur easily defectives such as tail triangle when the rolling thin-wall pipe, the lighter influences product quality, weight person causes technology accidents such as rolling card easily.
(4) quality of rolling hollow forging depends on the quality that equipment is adjusted to a great extent.And the relation of device context adjustment quality and workman's quality, control level and equipment precision is very big, is a uncertain factor.
Summary of the invention
Purpose of the present invention is studied with regard to the deficiency that above-mentioned existing three roll pipe machine technology exists, it is good to have designed rigidity of frame, hydraulic locking, have that roll leaves soon and frame quick change function, change the online line that is adjusted into of traditional pass and assemble adjustment outward, make the pass size guarantee to change into machinery assembling assurance, can shorten non-cutting time greatly by adjusting, the effective operation rate of raising equipment has improved the dimensional accuracy of adjusting precision and shutting out hollow forging.
For achieving the above object, the technical solution used in the present invention is:
Three-roll pipe mill, comprise three cover roll devices in the main motor, transmission device, closed frame, frame, and three covers adjust transmission and the bascule that rolls are depressed; It is characterized in that: frame and base are separable, are provided with gantry base and push-and-pull and locking device below the frame, and frame is realized fast assembling-disassembling and is fixed on the base reliably by push-and-pull and locking device; Power transmission shaft and roll in the transmission device are provided with rapid dismounting apparatus, and hydraulic pressure on the frame, lubricated pipe arrangement are furnished with snap joint with peripheral lubricating utensil, and electrical equipment is powered with the periphery and the interface of control appliance also is furnished with quick socket and is connected.
