Description

High-precise section rolling device

The utility model belongs to the metallurgy rolling plant equipment, particularly a kind of precision rolling device that is used for the high accuracy section bar after the shape rolling mill finished product frame that is installed in.

In smelter, existing shaped steel rule circular knitting machine, scale machine generally have a posture, two to add multiple modes such as formula, three postures, and they are not all having weak point on the degree together.Can only control the size of a direction of product as: posture rule circular knitting machine, to reverse the size that is caused out of control and can't solve because of rolled piece; Three postures rule circular knitting machine often has the edger roll of not transmission, when mill speed is higher, accidents such as steel-fastening takes place easily; Two posture precision rolling devices are to adopt no memorial archway open frame structure, and horizontal roller adopts to give and compresses working method, lack the flexibility of axially adjusting, and cost is again than higher.

Day disclosure is speciallyyed permit the disclosed a kind of vertical horizontal mill unit of clear JP61-27106, and each interior framework comprises vertical roller group and horizontal roller group, transmission edger roll and the universal-joint spindle mode is arranged in employings, and structure is compactness inadequately.China Patent No. is that disclosed a kind of " the isoplanar universal mill in the open-train mill " is to constitute omnipotent pass by plain-barreled roll and edger roll in same vertical plane among the CN87203808U, be installed in the open-train mill machine row, be mainly used in the flank processing of section bar, and can not eliminate rolled piece cross section and longitudinal size deviation effectively.

The purpose of this utility model be for eliminate rolled piece vertically with the dimensional discrepancy in cross section, and the two-shipper frame rolling device that provides upright flat two close-coupleds of a kind of pony roll footpath, short central distance to arrange places after the section bar finished frame, with the realization precision rolling.

The utility model mainly is made of standing roller frame, plain-barreled roll frame, unit framework and transmission system, in design, adverse effects such as existing milling train is big because of spreading of bringing greatly of roller footpath in order to overcome, roll-force increase, moment increase, adopted the working roll in pony roll footpath to be rolled, its roller footpath only is 0.4～0.7 times of finished frame roller footpath; More compact for the flexural deformation and the machine packet size of making that reduce roll, adopt short roller body B=90～160mm; And the close-coupled frame that adopts high rigidity, short central distance, horizontally and vertically alternative to arrange, the frame central distance only is 1.5～2.5 times of roller footpath.Within being installed in after the milling train finished frame whole unit closely, the standing roller frame center line is about directly 3～5 times of roller in this device of finished frame centre-to-centre spacing, and its major technique is characterised in that:

1. standing roller frame adopts the underdrive mode, replaces universal-joint spindle with movable umbrella gear box.One of two umbrella gear box of transmission edger roll are fixing, and one movable, and the movable umbrella gear box and the screw-down of edger roll are realized action synchronously by set of gears mechanism, to guarantee the edger roll stable drive.

2. utilize unit framework that plain-barreled roll frame and standing roller frame are linked to be an integral body apart from ground continuously, fix with pull bar and the reliable and stable memorial archway of seaming realization, the unit mounting or dismounting are convenient, compact conformation.

3. horizontal roller and edger roll all use the profile of tooth that is positioned at the same side to take over the moment of torsion that transmits from motor, along slide rail whole unit framework hauling-out after taking apart, is hung away the profile of tooth catcher during roll change, simultaneously another is organized that the mounted unit framework of off-line pushes roll line along slide rail, realize fast roll changing.

The utility model is through trial run, can eliminate rolled piece cross section and longitudinal size deviation effectively, make the finished size tolerance be controlled at current international practice standard 1/2nd to 1/4th in, improve product percent of pass significantly, for enterprise creates considerable economic, this device has compact conformation, stable drive, advantages such as easy accessibility not only are used for the precision rolling of round steel, and can be widely used in the precision rolling of section bar.

Embodiment below in conjunction with in the accompanying drawing is described in detail the utility model.

Fig. 1 is edger roll pass and plain-barreled roll pass schematic diagram.

Fig. 2 is the vertical view of this device.

Fig. 3 is the side view of this device.

(1) is the edger roll motor among the figure, (2) be the profile of tooth catcher, (3) be the edger roll bearing block, (4) horizontal roller motor, (5) are gear-box, (6) be universal catcher, (7) be adjusting device, (8) are unit framework, and (9) are pull bar, (10) be nut, (11) be standing roller frame, (12) are the edger roll mechanism for axial adjusting, and (13) are bearing block, (14) be the edger roll screw-down, (15) be cushion block, (16) are bevel gear, and (17) are umbrella gear box, (18) be slideway, (19) be the edger roll catcher, (20) are bearing, (21) have the edger roll bearing block of tarpaulin for downside, (22) are guide and guards, (23) be bearing block, (24) be the horizontal roller axial adjusting device, (25) are horizontal roller, and (26) are the horizontal roller frame.

The structural principle of this device is, edger roll motor (1) is by the bevel gear (16) in profile of tooth catcher (2) transmission umbrella gear box (17), when adjusting the depressing of edger roll, utilize gear and housing screw to drive umbrella gear box (17) in the edger roll screw-down (14) along slideway (18) and edger roll bearing block (3) synchronization action, and to adopt spline and slideway (18) be that movable umbrella gear box (17) leads, and this mode has been saved traditional universal-joint spindle mode.Bevel gear bearing (16) is housed in the bevel gear (17), edger roll catcher (19) couples together bevel gear bearing edger roll (3), the edger roll bearing block (21) that upside edger roll bearing block (3) and downside have tarpaulin is housed in the edger roll memorial archway, and the guide and guards (22) that is fixed together by seaming mode and edger roll memorial archway (11), edger roll mechanism for axial adjusting (12) utilizes gear and screw to allow edger roll to do trace adjustment vertically, aligns to guarantee pass.The principle of horizontal roller axial adjusting device (24) and structure are all similarly, horizontal roller (25) two ends have bearing block, axial adjusting device (24) wherein is housed above the fore side bearing block (3), and horizontal roller motor (4) is by gear-box (5) and universal catcher (6) transmission horizontal roller (25).Standing roller frame (11) all links to each other with unit framework (8) by seaming with horizontal roller frame (26), and is tightened to one by pull bar (9) and nut (10), has constituted frame-type two-shipper frame high accuracy precision rolling device.

The main purpose that this device is depressed rolled piece is not to pursue to extend but the elimination dimensional discrepancy, so general section shrinkage rate is less than 6%.Accompanying drawing 1 is upright flat two passes, wherein the main effect of vertical pass is the size of control rolled piece dual-side, simultaneously closely leave abundant leeway at the roll gap annex, guarantee the unlikely defective such as the ears or side handles of a utensil that occurs of rolled piece, the main effect of plain barrel pass is the size of the control rolled piece top and bottom and two cheeks, compare with traditional round steel finished product hole, the plain barrel pass of this device more approaches standard round.
