Abstract
The invention discloses a non-driven on-line flat steel hot straightening machine comprising a roller way, roller way stands and vertical rollers. The vertical rollers are vertically arranged on the roller way stands at two sides of the roller way; each vertical roller on one side of the profile projections of the roller way stands and the vertical roller is arranged between the vertical rollers on the other side; and the surfaces of the two vertical rollers contact with the surface of the side edge of on-line flat steel. The invention makes the curvature and the surface quality of finished flat steel meet the requirements of users, improves the finished flat steel by more than 96 percent and has the advantages of convenient production operation and equipment maintenance and energy saving.
Description
Technical field:
The present invention relates to iron and steel enterprise's production line of bar, be specifically related to the bar on-line thermal straightening device.
Technical background:
When producing band steel with production line of bar, the particularly production of right angle pallet fork and mould band steel, owing to steel temperature, roll cooling water, import and export guide and guard and rolled piece reason such as nip, the bending (camber) that the band steel head occurs in various degree is difficult to avoid, but the client requires strictness especially to the flexibility of band steel, and every meter flexibility requires to be not more than 3 ‰, and this has just increased milling train greatly and has adjusted time and adjustment difficulty, even so also can produce substandard products, have a strong impact on the quality of finished steel.In order to guarantee that the steel bending degree can satisfy user's requirement, have to the steel head of bending is amputated by single multiple lengths in the production, this has had a strong impact on lumber recovery (lumber recovery has only about 92%), has increased production cost virtually.
Existing " a kind of band steel on-line straightening device " patent is that the guide groove both sides respectively add an adjustable A, B plate behind finished frame, and the inlet of A, B plate is made horn mouth, is convenient to import band steel.When have the curved band steel of lateral bending or S between A, B plate by the time, obtained aligning by force, the lateral bending and the S that have eliminated band steel are curved.But there is inevitable shortcoming in this mechanism, mainly shows following 2 points:
The one, the A of straightener, B plate and finished product band steel side are aligned by plane contact, wear and tear its surface easily and produce distortion, influence leveling effect, so the service life of A, B plate is shorter.
The 2nd, when straightener used, A, B plate scratched the surface of the finished product band steel side of high temperature easily, made finished steel produce major defect, influences surface quality, and aligned intensity and diminish, and be undesirable for big specification right angle pallet fork and mould band steel leveling effect.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of non-driven on-line flat steel hot straightening machine, and this straightener is aligned for the line that rolls contacts with the band steel side, can not scratch the finished product band steel side edge surface of high temperature in the aligning process, and leveling effect is good.
The present invention is achieved through the following technical solutions:
Non-driven on-line flat steel hot straightening machine, constitute by roller-way and roller bed frame thereof and vertical rolls, described vertical rolls is vertically installed on the roller bed frame of roller-way both sides, the side projection of roller bed frame and vertical rolls thereof, each vertical rolls of one side is between the opposite side vertical rolls, and the roll surface of both sides vertical rolls touches mutually with online band steel side edge surface.
2-4 vertical rolls is set respectively on the roller bed frame of described roller-way both sides, and the diameter of vertical rolls is 150～300mm, and the distance between each side vertical rolls is 250～350cm.
The present invention has the following advantages:
One, the present invention is that 150～300mm vertical rolls constitutes by roller-way and roller bed frame thereof and 5 to 7 diameters, the diameter of vertical rolls can be changed according to the specification size of band steel, spacing between the vertical rolls of roller-way both sides can be regulated by the screw rod that is connected with the vertical rolls roller seat, with the back-flexing degree of adjusting band steel and the band steel aligning that adapts to different size.
Two, the present invention is installed on position, the 1m left and right sides behind the finished frame in using, hot material aligning (steel are good 800～950 ℃ of plasticity) when not only helping just having gone out frame, and the roll-force of having utilized finisher promotes the vertical rolls rotation, need not external force drives, production operation and plant maintenance are very convenient, simultaneously energy savings.
Three, the present invention is carrying out in the aligning process band steel, the bilateral vertical rolls produces rolling friction with the band steel side edge surface of being aligned, received good effect to preventing that band steel from reversing to scratch with side, not only make the finished steel flexibility satisfy customer requirements, and the surface quality of finished steel satisfy customer requirements equally.Owing to there is not a head-bent, reduce crop length (every base about 1.2 meters), the band steel lumber recovery is reached more than 96%, lumber recovery improves 3.0%～4.0%.
Four, reduced the adjustment and the operation easier of milling train, improved operating rate, output is increased to about 600 tons for about 400 tons by original per tour.The present invention can promote the use of at similar band steel production line.
Description of drawings:
Fig. 1 is a schematic top plan view of the present invention;
Fig. 2 is Figure 1A direction schematic diagram (having increased outlet guide plate diagram).
The specific embodiment:
As shown in Figure 1, 2, the present invention is made of roller-way 1 and roller bed frame 2 thereof and vertical rolls 3.Vertical rolls 3 is vertically installed on the roller bed frame 2 of roller-way 1 both sides (in the present embodiment, the roller bed frame of roller-way one side is provided with two vertical rollses, opposite side is provided with three vertical rollses), the side projection of roller bed frame 2 and vertical rolls 3 thereof, each vertical rolls 3 (as shown in Figure 1) between opposite side vertical rolls 3 of a side.The roll surface of both sides vertical rolls 3 touches mutually with online band steel side edge surface.
Still as shown in Figure 1, 2, the roll shaft of vertical rolls 3 is fixed on roller seat 4, described roller seat 4 is provided with and the vertical inner bolt hole in roller-way 1 axis plane, screw rod 5 one ends stretch into inner bolt hole, the protruding roller bed frame 2 of the other end also is movably connected on roller bed frame 2 (also can connect by bearing) by axle sleeve, and this termination that screw rod 5 stretches out roller bed frame 2 is provided with shakes the hand 6.By the distance that 6 rotating screw bolts 5 of shaking the hand are regulated between the vertical rolls of both sides, the band steel aligning needs of adjusting the back-flexing degree of band steel and adapting to different size.Described roller seat 4 is provided with stopper slot 9, when use shake the hand 6 rotating screw bolts 5 regulate between the vertical rollses of both sides apart from the time, the both sides of roller seat 4 move around in stopper slot 9.
As shown in Figure 2, roller-way 1 both sides and vertical rolls 3 relative positions are provided with the recess 7 of regulating both sides vertical rolls 3 spacings, and described recess 7 width are greater than the radius of vertical rolls 3.Still as shown in Figure 2, the roller-way of vertical rolls 3 one sides is provided with the foreplate or the guide and guard groove 8 of vertical rolls 3.
It is 150cm that the present invention is used for width, and when thickness was the band steel aligning of 50cm, the diameter of vertical rolls was generally elected 200mm as.
