The specific embodiment
The utility model is described in further detail for the contrast accompanying drawing:
A kind of transverse straightener described in the utility model, agent structure comprises control device, preceding feeding guide roller 1A and back feeding guide roller 1B, before back feeding roller-way 2B is installed between feeding guide roller 1A and back feeding guide roller 1B, the distance of preceding feeding guide roller 1A and back feeding guide roller 1B should be less than the length of correcting sheet material.Pinch roll 4A before back feeding guide roller 1B one side is installed, preceding pinch roll 4A one side is provided with a pair of preceding laterally smoothing roll 6A, 6C, and preceding horizontal smoothing roll 6A, 6C vertically set up, and separate from slab delivery track both sides, and can be at width upper mounted plate base.Preceding laterally smoothing roll 6A, 6C one side are provided with plate straightening roll 7, plate straightening roll 7 one sides are provided with a pair of back laterally smoothing roll 6B, 6D, laterally smoothing roll 6B, 6B vertically set up in the back, separate from slab delivery track both sides, and can be, and slab is applied straightening force align at width upper mounted plate base.The back laterally side of smoothing roll 6B, 6D is provided with back pinch roll 4B, laterally smoothing roll 6B, 6D are connected with power set respectively with the back for preceding laterally smoothing roll 6A, 6C, described power set can be motor, hydraulic cylinder or pneumatic cylinder, the preferred servo-cylinder that adopts, servo-cylinder has the advantage that power output is stable, power is high, as shown in Figure 2, laterally smoothing roll 6B, 6D are connected with each servo-cylinder respectively with the back for preceding horizontal smoothing roll 6A, 6C.Back pinch roll 4B one side is provided with discharging guide roller 1C, and discharging guide roller 1C one side sets out material roller road 2C, and back feeding roller-way 2B goes up first checkout gear is installed, and described first checkout gear to the distance of preceding pinch roll 4A should be greater than the maximum length of slab.Discharging roller-way 2C goes up second checkout gear is installed, and control device is connected with second checkout gear with power set, plate straightening roll 7, first checkout gear respectively.
Described checkout gear preferably adopts laser detecting apparatus, and promptly first checkout gear is the first laser detecting apparatus 3A, and second checkout gear is the second laser detecting apparatus 3B, and laser detecting apparatus has the accuracy of detection height, the advantage that efficient is fast.
Feeding for convenience, the utility model is feeding roller-way 2A before preceding feeding guide roller 1A one side is provided with, feeding guide roller 1A both sides before preceding feeding roller-way 2A and back feeding roller-way 2B lay respectively at.
A kind of transverse straightener described in the utility model is not only applicable to the automobile longitudinal girder slab is laterally aligned, and can also have the narrow boards band of the ferrous metal of camber or waveform bending and non-ferrous metal or slab etc. to other edge and align.
When the utility model uses, before the automobile longitudinal girder slab is placed on the feeding roller-way 2A, slab by preceding feeding guide roller 1A after locating on its width at the uniform velocity forward (described front side promptly as shown in Figure 2 right side) send to.After slab entered back feeding roller-way 2B, the first laser detecting apparatus 3A shone the slab edge with 3 some lasing light emitters as measuring basis, once obtains the position data of three points on the slab edge.Send in the process at slab, three some lasing light emitters are gathered a secondary data at a certain distance, thereby obtain the related data of sickle curve of plate blank.Three some lasing light emitter mutual distance operated by rotary motion are at 1m.Before the slab front end arrives during pinch roll 4A, the first laser detecting apparatus 3A has detected the total length of slab, and will detect data and be sent to control device, the slab marginal position data that at every turn record according to three some lasing light emitters, control device can calculate the radius of curvature of slab at the camber curve at this section edge, and according to horizontal smoothing roll 6B after the radius of curvature adjustment of each section, the active force of 6D, adjust the backing roll height and position of close recessed crimp one side of this place's camber in the plate straightening roll 7 simultaneously, camber to slab is laterally aligned piecemeal, can improve flattening precision greatly like this.
Its concrete operations are: behind horizontal smoothing roll 6A, the 6C, preceding horizontal smoothing roll 6A, 6C clamp the plate both sides under the control of corresponding servo- cylinder 5A, 5C before the slab front end enters.The plate front end enters the back laterally when smoothing roll 6B, 6D through plate straightening roll 7,, slab is carried out pressure correct in horizontal plane laterally under the driving of the corresponding servo-cylinder 5B of smoothing roll 6B, 6D, 5D in the back.For example when the camber male bend limit of slab up when (i.e. top as shown in Figure 2), laterally smoothing roll 6B, 6D move upward in the back.Send in the process at slab, this gag press straightening is carried out continuously, just the back laterally the straightening force that applies of smoothing roll 6B, 6D be to detect to such an extent that the curvature of camber is constantly adjusted according to the first laser detecting apparatus 3A by control system.Continuous gag press straightening makes the recessed crimp fiber tension elongation of camber, and when bending moment increased to certain numerical value, recessed crimp surface reached plastic deformation, thereby camber is reduced until disappearance.Laterally when smoothing roll 6A, 6C, transverse pressure aligning process finishes before the slab rear end is left.
In this continuous transverse aligning process, slab is lived in the numerous leveling roll-ins on the plate straightening roll 7, and the located lateral of slab in horizontal plane also played a role.Concrete operations are: control device can be adjusted the height and position that each group on the plate straightening roll 7 supports according to testing result.When slab enters plate straightening roll 7, under the effect of staggered leveling roller,, make and obtain slab and get glacing flatness preferably through repeatedly alternating bending.Simultaneously, adjustment plate straightening roll 7 is respectively organized backing roll and is had different height and positions, makes recessed crimp one side of camber of slab that bigger drafts be arranged, and produces certain longitudinal extension.And camber male bend limit one edging is less, does not produce longitudinal extension, so just can reduce the camber of slab.
In the utility model, before introducing slab, preceding pinch roll 4A when horizontal smoothing roll 6A, 6C, promptly determined the reference position of slab on width.Before slab enters sheet flattening machine 7, control system is according to the slab edge camber parameter that measures, the backing roll height and position of respectively organizing to sheet flattening machine 7 is adjusted respectively, strengthened the drafts of the recessed crimp one side bearing roller of slab, make recessed crimp one side of slab produce certain plastic elongation, to reduce camber.When the slab front end enters the back laterally when smoothing roll 6B, 6D, under servo-cylinder drives, in horizontal plane, slab is carried out pressure and correct.
Continued at the uniform velocity to send to the right by discharging guide roller 1C through the slab after laterally aligning, at this moment, the second laser detector 3B detects once more piecemeal to the slab edge, judges whether the edge line degree reaches requirement.Enter next process behind the qualified slab stacking, do not meet the requirements of slab and will enter the utility model once more and align.
