Description
Technical field
The utility model belongs to milling equipment technical field, more particularly, relates to a kind of mill guide beam effectively preventing to loosen.
Background technology
At present, mostly the processing of plate, wire and rod, be to adopt mill milling.And steel usually needed to adopt guide beam to carry out leading position before being rolled, thus control the entry angle of steel, enable steel accurately, stably enter roll pass according to set direction and state, and then steel can be made stably to enter in wire casing be rolled.The structural stability of mill guide beam can affect the accuracy leading position to a certain extent, thus affects the quality of rolled piece and the height of rolling efficiency.
Before guide beam of the prior art is normally fixed on the roll pass of milling train, as shown in Figure 1, it mainly comprises that two of being symmetrical set lead a bracket 2, entablature 1, sill 3, hold down assembly, slide rail 4 and lead screw assembly 5, wherein, leading a bracket 2 for two is set on a pull bar, the two ends of entablature 1 are connected with the upper end of two pull bars respectively, the two ends of sill 3 are connected with the lower end of two pull bars respectively, and entablature 1, sill 3 and two pull bars form a quadrilateral frame.Be provided with at the middle part of above-mentioned entablature 1 and hold down assembly, this holds down assembly and comprises down screw rod 10, adjusting sleeve 9 and brake block 11, adjusting sleeve 9 is plugged in the middle part of entablature 1, one end of down screw rod 10 is connected with brake block 11 through adjusting sleeve 9, the other end of down screw rod 10 is fixed on the top of entablature 1 by nut, lead a bracket 2 for two can drag entablature 1 and move up and down along pull bar, thus drive pressure assembly to be fixed steel rolling.Above-mentioned lead screw assembly 5 is positioned at the below of sill 3, slide rail 4 can be driven to move linearly along the upper surface of sill 3 by lead screw assembly 5, thus regulates the horizontal level of rolled piece, enables rolled piece aim at roll pass.But because guide beam of the prior art is fixed on milling train by bolt 6, the guide and guard be fixed in the operation of rolling on guide beam are often subject to the shock of steel billet, thus cause guide beam to occur to loosen relative to milling train, and then cause guide and guard not import in the hole slot of milling train by steel billet exactly, cause heap steel, and then affect production efficiency.
In order to solve the problem that above-mentioned guide beam easily loosens, be typically employed in prior art on rolling mill body and be welded and fixed block 8, and install tightening leading screw 701 and lower tightening leading screw 702 respectively two outer webs leading a bracket 2, make to tighten fixed thread thick stick 701 and lower tightening leading screw 702 holds out against fixed block 8, thus can make to a certain extent to install firmly between guide beam and milling train, prevent guide beam from occurring to loosen, but take technique scheme also can only prevent guide beam from occurring to loosen relative to milling train in the vertical direction, guide beam loosens then more serious in the horizontal direction.As Chinese Patent Application No.: 201220505571.7, the applying date: on September 29th, 2012, invention and created name is: the novel of a kind of milling train leads a boom device, novel in this application case leads a boom device, comprise brace summer, screw mandrel, four short screws, long bolts and lead a balladeur train, brace summer is fixed on milling train as main frame, and one end of four short screws contacts with brace summer, supports moving up and down of brace summer by moving up and down of short screw.This application case is arranged on the stability that namely can improve guide beam to a certain extent by four short screws, but guide beam loosening in the horizontal direction is still more serious.In addition, due to four between short screw with guide beam also for screw thread pair is connected, and steel billet is constantly clashed in the operation of rolling, thus cause the screw thread pair of four short screws also can loosen, thus make guide beam occur to loosen relative to milling train, make to lead location, position to be forbidden, cause billet rolling quality to be affected, and produce heap steel phenomenon.
