Definitions
- the invention relates to an overrun and braking device, especially for medium steel rolled sections, with a Infeed roller table and one in parallel assignment laterally offset braking device which in Working together form an overrun and braking system.
- Cooling bed lengths It is primarily about a higher speed of the entire material flow and about means and measures for orderly storage of rolled stock in adapted Cooling bed lengths.
- Such a device is for example from DE-OS 2 218 041 known. It follows that one from the Rolling rod running out of rolling mill first one Separating device for cropping the unusable head pieces of the Passed through the rolling rod and then on a ramp roller table reached. There is a brake roller table that can be lifted on one side activated and the braking of the moving Initiated. Such a brake roller table exists at known system from with a slight inclination to the rolling axis arranged transport rollers that the rolling rod over the Move the entire length to the cooling bed side. Once the roller bar laterally from the area of the overrun roller table onto the Deceleration roller table, it is lowered and the Overrun roller table is for the admission of a new rolling rod free again.
- the brake roller table is depending on the profile type of the Rolling rod controlled so that a cropping of the rod head in the separation device in a predetermined length can, or one in front of the Separating device lying end position is reached. if the Rolling rods are to be straightened, they pass one Straightening machine and are then over the outlet roller table the cooling bed.
- the braking device in Form arranged a brake roller table.
- Brake sliders have the disadvantage that at comparatively low rolling speeds no fast and safe lateral movement on the lifting brake slides he follows.
- tie rods become common Swiveling movement of the wipers that are thermally induced Length changes are subject to undesirable Can cause swiveling movements.
- a abrupt side wiping and the resulting Rough ejection movement in the side wall to deformation lead especially with thin-walled double-T profiles.
- the invention is based, an essential task to provide improved overrun and braking device, which a safe and quick cross-feed of rolled sections the entry area into the braking area while avoiding the allows the aforementioned disadvantages and difficulties.
- the Device should be straightforward, and in particular one Careful treatment of rolling stock without profile deformations guarantee.
- the overrun and braking device as a cooperating functional unit consisting of an infeed roller table with a lifting floor whose level is dominated by transport rollers and from a parallel assigned fixed brake trough formed is, the infeed roller table together with lifting floor and Transport rollers around a pivot point sunk to the side in an incline that slopes towards the brake trough can be swung open, becomes independent of the existing one Rolling speeds a quick and safe transverse movement on the transport level of the swiveling transport rollers reached.
- rollers stored on the lifting floor become one after running in Profiles raised together with the floor, causing after Reaching the upper stroke position due to the inclined position of the Systems easy and quick cross-conveying of the rolled stock is made possible.
- a rolled profile slides easily onto it set, rotating roles without risk of a Deformation transverse to the direction of transport in the braking area and is on this after lowering the roles in time Control braked quickly without risk of deformation.
- An embodiment essential to the invention provides that the infeed roller table together with the lifting floor and on it stored transport rollers by a laterally offset Pivot point in against the brake trough sloping incline can be swung out using swiveling means is trained.
- the brake trough and the infeed roller table are assigned to one another such that in raised position of the swiveling infeed roller table transport level formed by the transport rollers the bottom of the Brake trough protrudes at a parallel distance, the bottom and the lifting floor form a common inclined plane.
- Figure 1 shows the infeed roller table (1) and one in parallel assignment laterally offset Braking device in the form of a fixed brake trough (2), one facing the horizontal (x-x) to the outside inclined-sloping bottom (22).
- the neighboring one Infeed roller table (1) is designed with a lifting floor (10), its level (z-z) from transport rollers stored below it (11) is towered over. These roles cover both the width the infeed roller table (1) and the brake channel (2).
- the infeed roller table (1) together with its lifting floor (10) and those mounted on it Transport rollers (11) offset by one to the side Pivot point (20) in against the brake trough (2) sloping incline can be swung open with swivel means (21) trained.
- the infeed roller table (1) shows in the swung open position Figure 2. It can be seen that the brake trough (2) and the Infeed roller table (1) are assigned to each other such that in raised position of the swiveling infeed roller table (1) the transport plane formed by the transport rollers (11) the bottom (22) of the brake channel (2) at a parallel distance protrudes, the floor (22) and the lifting floor (10) one form common inclined plane (z-z). At this position of Infeed roller table (1) and brake channel (2) is after reaching the upper stroke position an easy and quick cross-conveying of the Rolled stock (30) possible.
- the rolling stock (30) slips onto the slightly set, rotating transport rollers (11) without Danger of deformation across the braking area of the Brake channel (2) and is in it by natural sliding friction slowed down gently.
- the Stroke movement of the pivoting means (21) can the entry of the Braking process can be controlled temporally and locally.
- the brake channel (2) in cross section a Z-shaped profile has with an adjacent roller table (1) downward leg (23) and one on the outside of the bottom (22) upwardly directed leg (24), the downward leg (23) when the Infeed roller table (1) as a side guide (25) for it promoted rolled sections (30) and the upward Leg (24) as a side guide (26) for in the brake channel (2) located roll profile (31, Fig. 3) is formed.
- the design of the device provides that the Infeed roller table (1) has an angular profile in cross section, with one of the transport rollers stored underneath (11) interspersed soil (10). This is on the outside of limited a vertical leg (27).
- the set angle can be between 2 and 20 degrees amount, preferably about 10 degrees.
- the design of the overrun and braking device provides that one stretched over the zenith of the transport rollers (11) Level some over the lifting floor (10) of the inlet channel (1) survives.
- a rolling rod (30) runs from a rolling mill Final rolling speed. After passing one Separating device for cropping an unusable head piece and occasionally after separating the rolling stock into pre-calculated ones Sections each section runs into the infeed roller table (1) the overrun and braking device. When you reach one predetermined by measuring means (not shown) The infeed roller table (1) is conveyed out of the position 1 with the rolled profile (30) conveyed thereon and with the transport rollers (11) after uninterrupted transport Activation of the pivoting means (21) in that shown in Fig. 2 Position swiveled up.
- the infeed roller table (1) is also the transport rollers (11) in the lowered position according to FIG. 3 (as also Fig. 1) lowered, whereby the profile (31) on the firm bottom (22) of the brake channel (2) comes to rest and is then braked by means of sliding friction.
- the device according to the invention is uncomplicated and effective and especially one gentle treatment of the rolling stock (30, 31) guaranteed.
- the invention optimally fulfills the above task.
