Abstract

The utility model discloses a hot straightening machine roller box with a support roller capable of being independently and directly arranged. The hot straightening machine roller box can be used for a heavy-load hot straightening machine in the iron and steel industry. Each support roller group I of an upper roller box I is directly arranged on an upper base I with a groove spigot; a plurality of lower support seats with groove spigots are arranged in a lower roller box I; a lower support seat freely falls and is arranged on a lower base I; a plurality of support roller groups I are arranged on each lower support seat; and a plurality of lubricating oil pipes are arranged between adjacent roller groups I in the upper roller box I and the lower roller box I and are respectively communicated with oil inlet holes and oil return holes of the support rollers. According to the hot straightening machine roller box disclosed by the utility model, a solid support roller is changed into a bearing type support roller, and thus the hot straightening machine roller box has the advantages of flexibility in rotation, great bearing capacity and low fault rate; the mode that a plurality of support rollers and an integral roller group form a group which is arranged on the roller box is changed into a mode that single support roller and two bearing plates form a group which is arranged on the roller box, and thus the convenience in replacement and detaching is realized, the central height of the support roller can be conveniently adjusted and further the assembly precision of the roller box is ensured.

Description

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

Technical field

The utility model 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

Thermal straightening machine is the heavily loaded metallurgical equipment that is used for aligning hot rolled plate on the hot rolling line, is widely used in iron and steel and non-ferrous metal industry, is used to eliminate the defectives such as limit wave, wooden dipper song of hot rolled plate, improves the plate face quality of hot rolled plate.The operation principle of thermal straightening machine is: when the elevated temperature heat rolling sheets gets into operating straightener; (interlocking is arranged in parallel smoothing roll about receiving; And rotation) active force of different directions and shown off waveform through straightener by repeatedly positive contraflexure, because inlet drafts big (being that pressure is big), the outlet drafts is little; The plastic deformation of sheet material to not having, makes unborn blemish be able to eliminate or improve by greatly.Common have nine roller straighteners, 11 roller straighteners.Template quality through behind the straightener aligning has many influence factors, and with regard to straightener itself, the roller box is its core, and its structure directly influences the complete machine precision, has also determined that can straightener the ordinary production operation simultaneously.

Fig. 8～14th, the roller box representative structure of prior art; There is following problem in it: 1. upper bed-plate 2 25, lower bottom base 2 26 rigidity are poor; Receive heavy straightening force effect in the work; And factor affecting such as hot environment and long term storage, all can cause the box-packed precision of joining of roller to reduce, directly influence the straightening quality of sheet material; 2. each backing roll group 2 20 all is made up of a plurality of backing rolls 2 21, and a plurality of backing roll 2 21 shared bearing blocks 23 belong to precision component, receives spatial constraints relatively weaker aspect size, is easy to generate distortion; 3. backing roll 2 21 is a solid construction, and taper roll bearing 22 supportings are adopted at two ends, and taper roll bearing 22 is prone to burn to death or break in the real work, need dismantle the shared bearing block 23 of a plurality of backing roll 2 21 during replacing, the maintenance operation difficulty; The backing roll group 2 20 of 4. relative with lower roll box 2 17 top roll box 2 18 is connected from the bottom surface is installed by screw 3 19, the dismounting inconvenience; 5. can not obtain the adjustment compensation after the assembly precision forfeiture, the big deviation of the high appearance in the center of several backing rolls 2 21 of same row, smoothing roll 2 24 can not keep good the contact with backing roll 2 21, causes the assembly precision premature failure because of stress changes.

Summary of the invention

For overcoming the deficiency of prior art, the goal of the invention of the utility model is to provide a kind of backing roll can be direct separately

The thermal straightening machine roller box of installing is to realize stable performance, overhaul conveniently, can keep assembly precision for a long time and to satisfy the purpose of technological requirement.

For realizing above-mentioned purpose, each backing roll group one of the top roll box one of the utility model all is directly installed on the upper bed-plate one of band groove seam; The lower support seat that several have the groove seam is housed in the lower roll box one, and the lower support seat freely falls to being placed on the lower bottom base one, and several backing roll groups one are installed on each lower support seat; Be arranged with lubricating oil pipe between the adjacent backing roll group one in top roll box one and the lower roll box one, lubricating oil pipe one, oil pipe two respectively with the advancing of backing roll, spill port UNICOM.

Said backing roll group one is connected with two support plates separately by some single backing rolls one and forms, and support plate is fastened on upper bed-plate one, the lower support seat through screw two, screw one respectively, and backing roll one is the bearing-type backing roll of the full roller structure of biserial; There is a boss bottom surface of support plate, and the boss both sides have screw hole, and the middle part has pin-and-hole; Upper bed-plate one is provided with positioning spigot, pin-and-hole and the screw hole of fixing each support plate; The lower support seat is provided with groove seam, pin-and-hole, the screw hole of fixing each support plate.

The utility model changes solid formula backing roll into the bearing-type backing roll, and bearing capacity is improved; The installation of backing roll group on the roller box is made up of a plurality of backing rolls and solid housing one group changes single backing roll into and two support plates are one group, make to change dismounting and become convenient, and the adjustable center of repaying backing roll of reorganizing and bringing up to full strength is high; The utility model has changed the structure of upper and lower base when changing backing roll group mounting means, the rigidity of straightener roller box is greatly improved at longitudinal direction.

The utility model compared with prior art has the following advantages:

1, rotate flexibly: bearing-type backing roll one staring torque is little, rotates flexibly, occurs the mutual phenomenon that abrades in the time of can avoiding smoothing roll contact with backing roll moment.

2, high adjustable the reorganizing and bringing up to full strength in center repaid: the roller group that " bearing-type backing roll-support plate " formed can be dismantled separately, is beneficial to maintenance and changes, and can conveniently adjust compensation to single backing roll one center height.

3, bearing capacity improves: bearing-type backing roll one is the full roller structure of biserial, and bearing capacity is big.

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

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