Description
Technical Field
The invention relates to the technical field of flat steel rolling, in particular to a vertical universal rolling mill for die flat steel, a flat steel rolling production line and a flat steel rolling method.
Background
The die flat steel is a section steel with a rectangular section, and the horizontal side and the side of the rectangle are vertical (the vertical degree of the horizontal side and the side is a key factor for evaluating the quality of a flat steel product). The method is widely applied to the field of die manufacturing, and the demand of the die flat steel is increasing along with the development of China in the field of die manufacturing. The current common rolling process is to roll the thickness of flat steel by adopting a two-roller horizontal rolling mill and the width of the flat steel by adopting a two-roller vertical rolling mill (in order to ensure the verticality of a horizontal side and a side, the common pass rolling is not adopted as far as possible (in pass rolling, a rolled piece is clamped by a pass side, and no steel turnover is generated), but a non-pass smooth roll with a completely flat roll surface is adopted for vertical rolling). The flat steel is rolled in the horizontal rolling mill stably, and the roll gap precision and the levelness of the rolling mill only need to be controlled well. When the flat steel rolled piece is rolled in the two-roller vertical rolling mill, the rolling deformation is unstable, and the steel turnover phenomenon often occurs. The reason for this is analyzed as follows:
as shown in fig. 1, when the roll 21 of the conventional two-roll vertical rolling mill 20 rolls the side edge of the flat rolled product 2, the deformed state of the flat steel in the two-roll vertical rolling mill is a high rolled product deformation state, and the deformed state is an unstable state, in which the flat steel is rolled by the smooth roll, there is no restriction of the holding of the grooved side wall (in order to ensure the perpendicularity of the horizontal edge and the side edge, the conventional grooved rolling is not used as much as possible), so that the flat rolled product 2 is liable to tip over (so-called "roll-over"). However, if the smooth roll is not adopted, but the pass is added, the verticality of the horizontal edge and the side edge of the rolled piece cannot be well ensured, so most production plants finally select smooth roll pass-free rolling. Production has also proved this, which is the case at present more or less in most of the flat steel production plants existing in China. When the flat steel is rolled vertically, the accident rate is very high, and even under the condition that horizontal press rolls are added at the front and the rear of the vertical rolling mill, the problem cannot be completely solved. The main reason is that the horizontal press roll and the vertical roll are not on the same rolling plane and are limited by the diameter of the vertical roll, and a certain distance is required between the horizontal press roll and the vertical roll, namely, the flat steel rolled piece 2 can enter the horizontal press roll after leaving the two-roll vertical rolling mill. The flat steel rolled piece 2 enters the compression roller after being turned over in the roller 21 of the two-roller vertical rolling mill 20, and the turned-over flat steel rolled piece 2 is pressed back by the compression roller, so that the control effect is poor, and the turning over can not be stably controlled.

Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The utility model provides a vertical universal mill for mould band steel, includes two edgers 1 and two horizontal rolls 3, and two edgers 1 bilateral symmetry set up, and two horizontal rolls 3 are symmetry about setting up, and the axis of two edgers 1 and the axis of two horizontal rolls 3 all are located same vertical plane, and a rolling hole is constituteed with two horizontal rolls 3 to two edgers 1, and edger 1 is the drive roll, and horizontal roll 3 is the driven roll, and edger 1 has connected gradually drive mechanism and power unit, as shown in fig. 2 and fig. 3.
The axes of the horizontal rolls 3 are horizontal, the axes of the two horizontal rolls 3 are parallel to each other, the axes of the vertical rolls 1 are vertical, and the axes of the two vertical rolls 1 are parallel to each other. The two vertical rolls 1 have rolling reduction, that is, both the two vertical rolls 1 can roll down, and the two vertical rolls 1 perform a rolling action. The two horizontal rollers 3 have no rolling reduction, namely the two horizontal rollers 3 can do rolling action to adjust the gap between the horizontal rollers and the surface of the rolled piece but do not roll down the rolled piece, and the two horizontal rollers 3 only play a supporting role to prevent the flat steel rolled piece 2 from tipping when the left vertical roller 1 and the right vertical roller 1 roll down.
Why the width of the flat steel is not rolled by the vertical rolls 41 of the conventional general universal rolling mill 40 (shown in fig. 4). In the conventional general universal rolling mill 40, the vertical roll 41 is usually a driven roll, and the horizontal roll 42 is a driving roll, that is, the horizontal roll 42 is sequentially connected with a transmission mechanism and a power mechanism, while the vertical roll 41 is not connected with the transmission mechanism and the power mechanism. When the existing common universal rolling mill is used for carrying out the reduction rolling on the side width of the flat steel, the passive vertical roller 41 is used for carrying out the reduction rolling, and the active horizontal roller 42 is preferably not used for carrying out the reduction rolling (because if the horizontal roller 42 is pressed down, a gap is formed between the outer side of the horizontal roller 42 and the roller surface of the vertical roller 41, a bulge is generated at the gap between the outer side of the maximum width of the horizontal roller 42 and the roller surface of the vertical roller 41 on the upper surface of a rolled piece, and the subsequent bulge is not easy to eliminate). At the moment, the vertical roller 41 is pressed down, but the transmission is not carried out by a motor, the rolled piece can be pushed to move forwards only by other rolling mills at the back, and the rolled piece drives the passive vertical roller 41 of the rolling mill to rotate and press down, so that the rolling mill is very inconvenient and easy to generate production accidents.
In the present invention, the width dimension of the flat steel rolled material 2 can be controlled by the left and right movements of the left and right vertical rolls 1. The height of the roll gap between the two horizontal rolls 3 is equal to the thickness of the flat steel rolled piece 2 or slightly larger than the thickness of the flat steel rolled piece 2, and the two horizontal rolls 3 only play a role of guiding and guarding in the rolling process. The two horizontal rolls 3 can be pressed down vertically, but the pressing down only has the function of adjusting the gaps between the upper and lower surfaces of the horizontal rolls 3 and the flat steel rolled piece 2, and the rolled piece thickness is not pressed down.
In this embodiment, the two horizontal rolls 3 are mirror images of each other and the two vertical rolls 1 are mirror images of each other. The vertical roll 1 is a driving roll, the vertical roll 1 is sequentially connected with a transmission mechanism and a power mechanism, the transmission mechanism comprises a connecting shaft 4, and the power mechanism comprises a main motor 6. The horizontal roller 3 is a driven roller, and the horizontal roller 3 is not connected with a transmission mechanism and a power mechanism. Two ends of the connecting shaft 4 are respectively connected with the vertical roll 1 and the main motor 6 through a coupler.
In the present embodiment, a constant gap L3 exists between the roll surface of the upper horizontal roll 3 and the roll surface of the left vertical roll 1, and a constant gap L4 also exists between the roll surface of the upper horizontal roll 3 and the roll surface of the right vertical roll 1. In the actual equipment design, the roll body length of the horizontal roll 3 can be set to only several specifications according to the width of a rolled piece to be produced specifically, so that the values of the gaps L3 and L4 are changed along with the selection of the rolling specification width and the roll body length of the vertical roll. The horizontal rolls 3 are used here as press rolls, and have no reduction, and serve to guide the rolled piece into the rolling mill and prevent the rolled piece from turning over.
The vertical universal rolling mill for die flat steel further comprises a stand, two vertical rolls 1 and two horizontal rolls 3 are fixed in the stand, a main motor 6 is fixedly connected with the stand, the connecting shaft 4, the coupling, the main motor 6 and the stand can adopt the prior art, and the connecting mode among the components can also adopt the prior connecting mode, namely the main invention point of the embodiment is that the common universal rolling mill is converted into the vertical universal rolling mill, the horizontal roll 42 of the prior common universal rolling mill 40 is used as the vertical roll 1 of the vertical universal rolling mill for die flat steel, the vertical roll 41 of the prior common universal rolling mill 40 is used as the horizontal roll 3 of the vertical universal rolling mill for die flat steel, the vertical roll 1 is used as a driving roll, and the horizontal roll 3 is used as a driven roll.
The vertical rolls 1 of the vertical universal rolling mill for die flat steel are arranged on the left side and the right side and are used for rolling the side edges of the flat steel, and the vertical rolls 1 are driving rolls and driven by a main motor 6, so that the biting rolling is easy to realize. The horizontal roller 3 of the vertical universal rolling mill for the die flat steel is a driven roller, is not driven by a motor, is used as a compression roller and is pressed on the upper surface and the lower surface of the flat steel. At the moment, the horizontal roller 3 does not have the reduction, and plays a role in guiding the rolled piece into a rolling mill and preventing the rolled piece from turning over.
The arrangement mode clamps the upper surface and the lower surface of a flat steel rolled piece 2 through a horizontal roller 3 of a vertical universal rolling mill, overcomes the production defect that steel is easy to turn over in the flat steel rolling process, and ensures the function of normally rolling the flat steel by pressing down the side edge of the flat steel through a vertical roller 1 with a motor.
A flat bar rolling line is described below, which comprises a plurality of two-roll horizontal rolling mills and a plurality of vertical universal rolling mills for die flat bars, which are arranged alternately in the rolling direction, the two-roll horizontal rolling mills being conventional two-roll horizontal rolling mills 30, and the vertical universal rolling mill for die flat bars being a vertical universal rolling mill 10 for die flat bars according to claim 1, as shown in fig. 5.
The rolling direction is a direction perpendicular to the paper surface of fig. 2 and directed to the inside of the paper surface, and corresponds to the left-right direction in fig. 5. The specific frame count of the two high horizontal mill 30 and the vertical universal mill 10 for the die flat is determined according to the rolling schedule. The rolling mills are finally determined according to the production specification and the blank specification of a specific workshop by specifically selecting a continuous rolling arrangement form or a reversible continuous rolling arrangement form. Preferably, in the flat steel rolling line, the first rolling mill is a two-high horizontal rolling mill 30, and the last rolling mill is also a two-high horizontal rolling mill 30, in the rolling direction.
