Abstract
The utility model discloses a straightener working roll fastening device which comprises a bearing seat, a roll system box and a fastening bolt. One end of the bearing seat is connected with the working roll. The other end of the bearing seat extends into the roll system box and is connected with one end of the fastening bolt. A T-shaped groove is arranged at an extending end of the bearing seat. The fastening bolt is a straight rod of the same diameter. One end of the fastening rod is provided with a T-shaped head corresponding to the T-shaped groove and connected with the bearing seat by being inserted into the T-shaped groove. The straightener working roll fastening device is capable of eliminating stress concentration points of the fastening bolt, obtaining a large movement space between the fastening bolt and the bearing seat during bending of a roller, enabling the fastening bolt not to be broken, being replaced conveniently at a machine on the condition that the fastening bolt is broken, needing no replacement of the whole straightener roller system and therefore greatly saving treatment time of a failure.
Description
Technical field
The utility model relates to straightener, more particularly, relates to a kind of working roller of straightening machine hangers.
Background technology
The thermal straightening machine of rolling medium plate is determining the height of delivery quality and the craspedodrome rate of product, and thermal straightening machine is a visual plant that is between Medium and Heavy Plate Rolling and the finishing.In rolling and cooling procedure, owing to have inhomogeneous deformation and inhomogeneous cooling, the flatness defects such as camber, horizontal wooden dipper song, limit unrestrained (monolateral or bilateral), middle wave, lonitudinal warping and distortion generally can appear in steel plate, and namely rolled piece has certain original curvature 1/r under original state.The Levelling principle of straightener is exactly to make rolled piece repeatedly back-flexing through staggered working roll in straightener, produce certain yield deformation at the horizontal section outer layer metal of steel plate, make the part elongation that length is short or stretch tight tightlyer, the unevenness of original curvature reduces gradually, thus the glacing flatness that acquisition needs and less residual stress.
Application along with the controlled rolling and cooling technology, finish to gauge and acceleration cooled steel billet temperature (450～600 ℃) on the low side, and the yield strength of steel plate improves a lot, thereby very high requirement is proposed the performance of thermal straightening machine, thereby promoted thermal straightening machine to negative load-bearing capacity and the development of high stiffness structure, for improving straightening quality, require straightener to possess multiple straightening function, and require the thickness range of aligning to enlarge many.
The Wide and Thick Slab thermal straightening machine is the all-hydraulic reversible thermal straightening machines of quadruple nine rollers, and stressed is divided into left and right sides two parts on its working roll, and there is pin joint at the middle part, and hydraulic cylinder can carry out roller to upper roller system by eccentric shaft and this pin joint.Four main hydraulic cylinder for reduction system are arranged at upper stressed top, and hydraulic cylinder for reduction system can be set roll gap by servo valve control, but the hydraulic cylinder for reduction system synchronization action, but also single movement can be realized upper roller system fascinating along steel plate length and width during single movement.Hydraulic cylinder for reduction system is provided with device for pressure measurement, but in the pressure release of when overload with protection equipment.
All adopted spring balancing for working roll was close in the design of bolster at straightener in when work, its balance be overbalance to be generally working roll be 1.2～1.4 times of weight, belong to the overbalance state.
The structure of traditional working roller of straightening machine hangers as shown in Figure 1, working roll 1 is installed on the bearing block 2, it is in the box 3 that bearing block 2 is installed in roller, and limit section is by liner plate 4 location, top at bearing block 2 is processed with screwed hole, hanging bolt 5 one ends are coupled, alignment pin 6 after tightening, is installed hanging bolt 5 again, so that hanging bolt 5 can not become flexible, working roll 1 after assembling is that to be installed to roller be in the box 3, it is box 3 that hanging bolt 5 other ends pass roller, and by pad 7, disk spring 8, positioning sleeve 9 and locking nut 10 are set, with roller be that box 3 is locked.
In actual use, when straightener to steel plates straightening the time, can use the roller function for guaranteeing plate surface quality, the roller function is exactly with working roll 1 bending, at this moment hanging bolt 5 will run-off the straight, the large outer radius of hanging bolt 5 will be run into the inwall that roller is box 3 mesopores, and it is disconnected to cause hanging bolt 5 to be broken off with the fingers and thumb.Straightener also has some other function such as working roll 1 inclination etc. also can cause the fracture of hanging bolt 5, so hanging bolt 5 fracture accidents often occur in the machine use, because being subjected to the installing space position limitation, can't change at machine after hanging bolt 5 fractures and process, must be to change lower machine with whole working roll 1, waste time and energy.
The utility model content
For the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of working roller of straightening machine hangers, the centrostigma that can eliminate stress, thus can avoid the hanging bolt fracture.
For achieving the above object, the utility model adopts following technical scheme:
This working roller of straightening machine hangers comprises bearing block, roller is box and hanging bolt, bearing block one end links to each other in working roll, it is to link to each other in the box and with hanging bolt one end that the other end stretches into roller, the inserting end of described bearing block is provided with T-slot, the shaft of described hanging bolt is the identical straight-bar of diameter, and an end is provided with and the corresponding T shape of T-slot head, and links to each other with bearing block by inserting in the T-slot.
The T-slot open side of described bearing block is provided with a baffle plate, and baffle plate fixes by set bolt and bearing block, and with the block of T shape in T-slot.
Described set bolt is two.
It is box that the described hanging bolt other end passes roller, and is that box fixes by setting gradually pad, disk spring, positioning sleeve and locking nut and roller.
In technique scheme, working roller of straightening machine hangers of the present utility model comprises bearing block, roller is box and hanging bolt, bearing block one end links to each other in working roll, it is to link to each other in the box and with hanging bolt one end that the other end stretches into roller, and the inserting end of described bearing block is provided with T-slot, and the shaft of described hanging bolt is the identical straight-bar of diameter, one end is provided with and the corresponding T shape of T-slot head, and links to each other with bearing block by inserting in the T-slot.Adopt this hangers can eliminate the stress concentration point of hanging bolt, larger activity space is arranged between hanging bolt and the bearing block when roller, so that hanging bolt can not broken off with the fingers and thumb is disconnected.And, even the hanging bolt fracture also can conveniently be changed at machine, will not change lower machine by whole roller system of straightening machine, therefore greatly saved fault handling time.
Description of drawings
Fig. 1 is the structural representation of the working roller of straightening machine hangers of prior art;
Fig. 2 is the structural representation of working roller of straightening machine hangers of the present utility model;
Fig. 3 is A section left view among Fig. 2;
