The thermal straightening machine roller box that backing roll can directly be installed separately, for the heavily loaded thermal straightening machine of steel industry.Each backing roll group one of top roll box one is directly installed on the upper bed-plate one of band groove seam; Roll box one is built with the lower bearing support of several band groove seams, and lower bearing support freely puts off on lower bottom base one, each lower bearing support is installed several backing roll groups one; Be arranged with multiple lubricating oil pipe between backing roll group one adjacent in top roll box one and roll box one, oil pipe enters with backing roll respectively, spill port UNICOM.The present invention changes solid formula backing roll into bearing-type backing roll, and rotate flexibly, bearing capacity is large, and fault rate is little; The installation of backing roll group on roller box one group of being made up of multiple backing roll and solid housing changes single backing roll into and two pieces of support plates are one group, changes convenient disassembly, and conveniently can adjust that to compensate backing roll center high, and the assembly precision of roller box is protected.

Description

The thermal straightening machine roller box that backing roll can directly be installed separately

Technical field

The present invention relates to iron and steel and non-ferrous metal industry technical field, is the thermal straightening machine roller box that a kind of backing roll can directly be installed separately specifically.

Background technology

The defects such as thermal straightening machine is heavily loaded metallurgical equipment hot rolling line being used for align hot rolled plate, is widely used in iron and steel and non-ferrous metal industry, unrestrained for the limit of eliminating hot rolled plate, wooden dipper is bent, improve the board surface quality of hot rolled plate.The operation principle of thermal straightening machine is: when high-temperature hot rolling sheets enters operating straightener, be subject to upper and lower smoothing roll (indenting arranged in parallel, and rotate) active force of different directions and shown off waveform by positive contraflexure repeatedly and pass through straightener, due to entrance drafts large (namely pressure is large), outlet drafts is little, the plastic deformation of sheet material, by greatly to nothing, makes unborn blemish be eliminated or improve.Common have nine roller straighteners, 11 roller straighteners.Template quality after straightener aligning has many influence factors, and with regard to straightener itself, roller box is its core, and its structure directly affects complete machine precision, and can also determine straightener normally production run simultaneously.

Fig. 8 ~ 14 are roller box representative structures of prior art, there are the following problems for it: 1. upper bed-plate 2 25, lower bottom base 2 26 poor rigidity, by heavy straightening force effect in work, and the impact of the factor such as hot environment and long storage periods, capital causes roller box assembly precision to reduce, and directly affects the straightening quality of sheet material; 2. each backing roll group 2 20 is made up of multiple backing roll 2 21, and the bearing block 23 that multiple backing roll 2 21 shares belongs to precision component, weaker in size by space constraint, easily produces distortion; 3. backing roll 2 21 is solid construction, and two ends adopt taper roll bearing 22 to support, and in real work, taper roll bearing 22 is easily burnt to death or breaks, and needs to dismantle the shared bearing block 23 of multiple backing roll 2 21, maintenance operation difficulty during replacing; The backing roll group 2 20 of 4. relative with roll box 2 17 top roll box 2 18 is connected from installing bottom surface by screw 3 19, and dismounting is inconvenient; 5. assembly precision can not be adjusted compensation after losing, and large deviation appears in the center height of several backing rolls 2 21 of same row, and smoothing roll 2 24 and backing roll 2 21 can not keep good contact, cause assembly precision premature failure because stress changes.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present invention is the thermal straightening machine roller box providing a kind of backing roll directly to install separately, with realize stable performance, maintenance convenient, assembly precision can be kept for a long time and meet the object of technological requirement.

For achieving the above object, each backing roll group one of top roll box one of the present invention is directly installed on the upper bed-plate one of band groove seam; Roll box one is built with several lower bearing supports with fluted seam, and lower bearing support freely puts off on lower bottom base one, each lower bearing support is installed several backing roll groups one; Lubricating oil pipe is arranged with between adjacent backing roll group one in top roll box one and roll box one;

Described backing roll group one is connected with two pieces support plate separately by some single backing rolls one and forms, and support plate is fastened on upper bed-plate one by screw two, is fastened on lower bearing support by screw one, and backing roll one is the bearing-type backing roll of the full roller structure of biserial.

There is a boss bottom surface of described support plate, and boss both sides are with screw hole, and middle part is with pin-and-hole.

Described upper bed-plate one is provided with the positioning spigot of fixing each support plate, pin-and-hole and screw hole; Lower bearing support is provided with the groove seam of fixing each support plate, pin-and-hole and screw hole.

The entering of the backing roll one of described top roll box one, spill port and oil pipe one UNICOM, the entering of the backing roll one of roll box one, spill port and oil pipe two UNICOM.

The present invention changes solid formula backing roll into bearing-type backing roll, and bearing capacity is improved; One group that the installation of backing roll group on roller box is made up of multiple backing roll and solid housing changes single backing roll into and two pieces of support plates are one group, replacing is dismantled and becomes convenient, and the center that adjustable compensates backing roll is high; The present invention changes the structure of upper and lower base while changing backing roll group mounting means, and the rigidity of straightener roller box is greatly improved at longitudinal direction.

The present invention compared with prior art, has the following advantages:

1, rotate flexibly: bearing-type backing roll one staring torque is little, rotate flexibly, can avoid occurring mutually abrading phenomenon when smoothing roll and backing roll instantaneous touch.

2, high adjustable in center compensates: the roller group that " bearing-type backing roll-support plate " forms can be dismantled separately, is beneficial to examine and replace, conveniently can carry out adjustment compensation to single backing roll one center is high.

3, bearing power increase: bearing-type backing roll one is the full roller structure of biserial, and bearing capacity is large.

4, easy to maintenance: " bearing-type backing roll-support plate " roller group all at the front screw fastening of roller box, is safeguarded very convenient;

5, rigidity improves: the rigidity that improve roller box base from structure, can disadvantageous deformation effect in improvement work, can the assembly precision of maintaining roller box relatively.
