Abstract

The utility model belongs to the technical field of rolling mills, which particularly relates to an axial adjustment mechanism of a roller of a rolling mill and solves the problem of low quality of a steel billet, which is caused by the irregular section of a blank rolled by a traditional 650 rolling mill. The axial adjustment mechanism of the roller of the rolling mill comprises the structure that both sides of the shaft end of a shaft box of the roller are respectively welded with an adjustment plate, and the end parts of the adjustment plates are provided with adjusting screws; and a seat is arranged on a rack of the rolling mill, a clamping block is fixed on the seat by a pin shaft, the position of the clamping block, which corresponds to the end parts of the adjustment plates, is provided with a groove, the outer side of the clamping block is provided with a positioning hole, a left supporting seat and a right supporting seat which rotate synchronously with the clamping block are also installed on the seat by pin shafts, a tightening bolt which is matched with the positioning hole is respectively fixed on the left supporting seat and the right supporting seat, and the end parts of the left supporting seat and the right supporting seat are connected by a left rotating adjustment screw sleeve and a right rotating adjustment screw sleeve. The utility model has the advantages that the mechanism has simple structure, the axial adjustment and the locking is reliable, the disassembly and the assembly are convenient, maintenance is not needed basically, and the quality of a rolled component is ensured and enhanced, so that full-line equipment has uniformity, and the use at a comparatively dangerous steel rolling site is more proper.

Description

The rolling mill roll mechanism for axial adjusting

Technical field

The utility model belongs to the milling train technical field, is specifically related to a kind of rolling mill roll mechanism for axial adjusting.

Background technology

Existing wire and bar mill field, 650 milling trains do not have mechanism for axial adjusting, make 650 milling train top and bottom rolls axially to adjust, and dislocation (as shown in Figure 1) might appear in lower pass on it, thereby make that the blank section that shuts out is irregular, influence following one rolling quality.

Summary of the invention

The utility model is irregular for the blank section that solves existing 650 milling trains and shut out, and causes the not high problem of billet quality, and a kind of 650 rolling mill roll mechanism for axial adjusting are provided.

The utility model adopts following technical scheme to realize:

The rolling mill roll mechanism for axial adjusting is characterized in that the adjustment plate perpendicular to roll axis that comprises that roll axle box axle head both sides are welded respectively, the end of adjusting plate along roll mandrel to both sides be respectively arranged with adjustment screw with roll axle box axially parallel; Be respectively arranged with seat on the rolling-mill housing of roll axle box axle head both sides, being fixed with by bearing pin on the seat can be relative to a clamp that rotates, the corresponding position of adjusting the plate end of clamp has groove, the position of corresponding adjustment screw is provided with wear plate in the groove, the clamp outside has locating hole, the left and right sides bearing that rotates synchronously with clamp also by bearing pin install present on, be fixed with the tight fixed bolt that cooperates with locating hole on the bearing of the left and right sides respectively, the end of left and right sides bearing by about tune the joint swivel nut and connect.

The utlity model has following beneficial effect: mechanism structure is succinct, axially adjust and reliable lock, easy accessibility, substantially need not safeguard, fill up the blank that 650 milling trains do not have mechanism for axial adjusting, guarantee and improved the quality of rolled parts, the designed reliability height, the use habit that meets the user also makes all fronts equipment have uniformity simultaneously, and it is more suitable to use at dangerous steel rolling scene.

Description of drawings

Fig. 1 can't axially adjust for existing 650 milling trains, the schematic diagram of last lower pass dislocation

Fig. 2 is a structural representation of the present utility model

Among the figure: the 1-650 topping roll, the 2-650 bottom roll, the 3-clamp, the 4-adjustment screw, the 5-seat tunes the joint swivel nut about 6-, 7-left and right sides bearing, the 8-tight fixed bolt, the 9-bearing pin, the 10-rolling-mill housing, 11-roll axle box, the 12-wear plate, 13-adjusts plate.

The specific embodiment

In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.

The rolling mill roll mechanism for axial adjusting, it is characterized in that the adjustment plate 13 that comprises that roll axle box 11 axle head both sides are welded respectively perpendicular to roll axis, the end of adjusting plate 13 along roll mandrel to both sides be respectively arranged with adjustment screw 4 with roll axle box 11 axially parallels; Be respectively arranged with seat 5 on the rolling-mill housing 10 of roll axle box 11 axle head both sides, being fixed with by bearing pin 9 on the seat 5 can be relative to seat 5 clamp that rotate 3, the clamp 3 corresponding positions of adjusting plate 13 ends have groove, the position of corresponding adjustment screw 4 is provided with wear plate 12 in the groove, clamp 3 outsides have locating hole, also install on present 5 with the left and right sides bearing 7 that clamp 3 rotates synchronously by bearing pin 9, be fixed with the tight fixed bolt 8 that cooperates with locating hole on the left and right sides bearing 7 respectively, the end of left and right sides bearing 7 by about tune joint swivel nut 6 and connect.

Specific operation process of the present utility model:

1, earlier with about tune 6 rotations of joint swivel nut left and right sides bearing 7 unclamped laterally.

2, rotation adjustment screw 4 makes bearing block and roll move to correct position.

3, again with about tune the rotation of joint swivel nut 6 left and right sides bearing 7 strain to the inside, and with clamp 3 clampings.

4, milling train can be started working.
