Description
Technical field
The utility model belongs to the improvement of cold-rolling mill rolling line wedge structure, and particularly the cold-rolling mill rolling line is adjusted the wedge device.
Background technology
The cold rolling unit rolling line of steel rolling mill, be installed in fixedly wedge and the wedge that is installed in the work that hydraulic cylinder drives under the roll change buggy on the mill housing underframe, to move the wedge wedge by hydraulic cylinder pushes and pulls out, utilize the inclined-plane roll is raised and to be fallen, with adjusting various frame height of rolling line, former ramp structure is easy to wear, scuffing and jam.The milling train wedge device of cold rolling unit in use once caused sliding surface to damage, movable wedge jam can't be adjusted, have to utilize repair time reconditioning sliding surface repeatedly, cause the wedge precision to continue to reduce, wedge adjusting equipment drifts about voluntarily when steel rolling, and stablizing of influence of rolled line repeatedly causes product quality defect, adopt regular manual intervention to recover roll line early stage, and template can not get reliable control like this.Wedge is the visual plant of unit, bears following function: 1, adjust the roll line absolute altitude each frame rolled band steel is passed through at same horizontal plane; 2, adjust working roll and backing roll position during roll change to roll change.3, adjust the wedge position automatically according to the indication of wedge hydraulic cylinder displacement transducer, make the band steel in the operation of rolling of tandem rolling unit, remain same plane and pass, guarantee the stability of continuous rolling, but because original-pack wedge structure is too simple, dynamic and static wedge is with material 42C
rM
oQuenched and tempered steel, relatively high pressure welding when causing local high spot steel rolling is brought in friction together, produces during slip that deep trouth scratches or the jam push-and-pull is motionless, not only influences roll change, roll location is demarcated the unstability that also causes the wedge self-locking, has a strong impact on the production of cold rolling mill.
Summary of the invention
The purpose of this utility model is to provide a kind of cold-rolling mill rolling line to adjust the wedge device, and it is rational in infrastructure, not only can improve the stability of wedge self-locking, guarantee constant product quality, and the service life that can improve the wedge device, equipment fault reduced, convenience easy to maintenance, maintenance cost is low.
The purpose of this utility model is achieved in that a kind of cold-rolling mill rolling line adjustment wedge device, comprise quiet wedge and the moving wedge that is slidingly matched with quiet wedge, on the sliding surface of quiet wedge, installing the wear-resisting copper lining board that matches with moving wedge sliding surface, dynamic pressure compensation oil duct is being set on the face that is slidingly matched of wear-resisting copper lining board, be positioned at and installing wedge on the sliding surface of the quiet wedge in the forward and backward two ends of wear-resisting copper lining board and scrape and sweep device, wedge is scraped the end face of sweeping device and is matched with the sliding surface of moving wedge.
During the utility model work, under the effect of the powerful impact external force of steel rolling, the fine generation self-locking of the big precision high energy of inclined-plane actual contact face because of copper lining board and moving wedge, because of dynamic pressure compensation oil channel structure design on the copper lining board make former under the situation of lubricating grease abundance, take place sliding inclined wedge and fixedly wedge adhesion and scratch phenomenon and no longer take place, because of sealing on the quiet wedge scrape the design of sweeping device make lubricating grease no longer bleed the bottom emulsion system, foreign can not engaging friction face.
Tandem mills rolling line wedge adjusting equipment is assemblied in each framework memorial archway window bottom, end face contacts with lower support roll bearing seat bottom, roll servo-actuated wedge inclined-plane raises and reduces, utilizing wearing and tearing to scrap dynamic and static wedge makes the blank design improvement and drives for the middle part adds and press the copper lining board and sealed at both ends the scraping of the design of compensation oil duct to sweep device, when producing, steel rolling can satisfy the requirement that the roll line absolute altitude is adjusted fully, reduce the wedge accident rate, reduce maintenance.Wedge maintenance is only changed copper lining board and is scraped and sweeps device and just can recover original precision, convenience easy to maintenance.And can promote the use of at similar unit according to this wedge project organization.The utility model is rational in infrastructure, not only can improve the stability of wedge self-locking, guarantees constant product quality, and the service life that can improve the wedge device, reduces equipment fault, convenience easy to maintenance, and maintenance cost is low.

The specific embodiment
A kind of cold-rolling mill rolling line is adjusted the wedge device, as shown in Figure 1 and Figure 2, comprise quiet wedge 2 and the moving wedge 1 that is slidingly matched with quiet wedge 2, on the sliding surface of quiet wedge 2, installing the wear-resisting copper lining board 3 that matches with moving wedge 1 sliding surface, dynamic pressure compensation oil duct is being set on the face that is slidingly matched of wear-resisting copper lining board 3, be positioned at and installing wedge on the sliding surface of the quiet wedge 2 in wear-resisting copper lining board 3 forward and backward two ends and scrape and sweep device 4, wedge is scraped the end face of sweeping device 4 and is matched with the sliding surface of moving wedge 1.As shown in Figure 3, the structure of dynamic pressure compensation oil duct is vertical main oil gallery 5 that the both sides on wear-resisting copper lining board 3 sliding surfaces of rectangle are being provided with symmetry respectively, be communicated with the laterally auxilliary oil duct 6 of inner side edge separately two uniform respectively settings in vertical main oil gallery 5 inboards, the wherein auxilliary oil duct 6 interlaced arrangements of two main oil gallerys 5, not connected, fuel feed hole 7 is being set on main oil gallery 5.The shape of main oil gallery 5 and auxilliary oil duct 6 is the uncovered oil duct with circular arc bottom surface, and wherein the cross-sectional area of main oil gallery 5 is bigger than the cross-sectional area of auxilliary oil duct 6.Because wear-resisting copper lining board 3 is provided with dynamic pressure compensation oil duct, moving wedge 1 pushes the auxilliary oil duct 6 of end sealing with lubricating grease by main oil gallery 5 when sliding, and unnecessary lubricating grease overflows and produces upwards thrust, produces oil film and separates and slide into pair.As shown in Figure 4, wedge is scraped and is swept device 4 and be made of polyurethane, scrapes on the end face outer long side of sweeping device 4 at the rectangle wedge lip limit 8 is set, and the rib 9 that is provided with on lip limit 8 and other three limits constitutes scraping of sealing and plays a minor role.The end face of rib 9 is an arc-shaped surface.Wedge is scraped and is swept device 4 and make the lubricating grease bottom emulsion system that no longer bleeds, and foreign can not engaging friction face.Lip limit 8 is used to scrape sweeps foreign and the inner lubricating grease that overflows of sealing, and rib 9 is used for scraping the power of sweeping and preventing 8 upsets of lip limit of balance lip limit 8.
