Description
Technical field
The present invention relates to the rolling machinery technical field, relate in particular to the integrated rolling mill axial adjusting device.
Background technology
In order to keep the tram of roll pass, need move axially or stationary roll and bear axial force and rolling torsion.Therefore,, be separately installed with axial adjusting device, general paired or single setting corresponding to the position of roll bearing in the outside of upright column of rolling mill.The purpose that axial adjusting device is set is to regulate the axial location of roll, guarantees import and export guide and guard and live pass to neutrality, thus the material shape size and the glacing flatness of control rolled piece.
At present, the shape rolling mill axial adjusting device is split type, divides three kinds of top rolls, central roll, lower roll, and the adjustment structure can be identical or different.As an example of this split type milling train axial adjusting device, describe with reference to figure 1 and Fig. 2.Like Fig. 1, shown in Figure 2, the bolt 11 of an end band pin-and-hole passes upright column of rolling mill 10 through holes, and bearing pin 13 will be adjusted pressing plate 12 and be positioned at up and down between a pair of bolt, and turn adjustment screw 14 realizes moving axially of breaker rolls or fixing.The shortcoming of this structure is: a, bolt locate with nut 15 from upright column of rolling mill is inboard, receive the influence of guide and guards such as crossbeam, can't clamp nut in the production process, and operation easier is big; B, stressed being prone to of nut are become flexible, and trip bolt frequently bears axial impact force, thread failure, and the transmission system unstability causes the plum-blossom connecting shaft and the roll roller crown to be hit, and adjacent milling train material shape is reversed, and answers back to import and export guide and guard and equipment; The pin-and-hole of c, bolt, bearing pin, adjustment pressing plate fit clearance are big, and bolt can't be fixed at upright column of rolling mill; D, complex structure, operation inconvenience, labour intensity is big, and milling train only plays the carry-over moment effect, adjustment material shape is unnecessary; E, technology accident are many, and transmission connecting shaft impacts mutually, the wearing and tearing of aggravation coupling box, cause beating technology accidents such as bald sleeve pipe, the distortion of roll roller head, interrupt producing continuously, the increase process rolls useless.
Summary of the invention
The present invention proposes in order to solve aforesaid problem, and its purpose is to provide a kind of easy and simple to handle and stable high integrated rolling mill axial adjusting device of axial restraint.
Integrated rolling mill axial adjusting device of the present invention; The integral shaft that comprise upright column of rolling mill, roll chock, is inserted into a plurality of button-headed bolts in the through hole of upright column of rolling mill, is used for fixing and adjusts roll chock to pressing plate, be formed on a plurality of oblate hole slot of integral shaft on pressing plate; Integral shaft is enclosed within respectively on a plurality of button-headed bolts of the through hole that passes upright column of rolling mill to a plurality of oblate hole slot of pressing plate through self; Add the semicolumn pad on a plurality of button-headed bolts respectively, through nut with it fastening and the location.
And it is two semicircle that the cross section, end of the oblate hole slot of integral shaft on pressing plate is.
And integral shaft position corresponding to roll chock on pressing plate is provided with opening.
And integral shaft is 20mm to the thickness of pressing plate.
Integrated rolling mill axial adjusting device of the present invention, owing to adopt integral shaft to pressing plate, so contact area is big, the stationary roll bearing block is firm.Integral shaft adopts oblate hole slot to pressing plate, and nut, semicolumn pad can closely contact with button-headed bolt, pressing plate.In addition, button-headed bolt is fixed on the groove in the upright column of rolling mill through hole through cup head, and therefore stressed all the time at a stable vertical plane, axial restraint is firm.And button-headed screw cooperates with upright column of rolling mill through cup head and does not rotate, and contact-making surface increases, and stress point increases, and fixed function is strengthened.
In addition, integrated rolling mill axial adjusting device of the present invention, simple in structure, change bearing shell, securing member is convenient.And clamp nut at any time in the production process is realized moving axially of breaker roll or fixing through the turn nut, and the adjustment operation is very easy.And labour intensity is low, and workload is few and little, does not need the post staffing.

The specific embodiment
Below, the embodiment that present invention will be described in detail with reference to the accompanying.At this, for the ease of explanation, describe as an example, and use identical symbol for identical part in the accompanying drawings with three-roller type steel rolling mill.
Fig. 3 representes the integrated rolling mill axial adjusting device of three contour roll forming steel milling trains of the present invention.The A-A line profile of Fig. 4 presentation graphs 3.
Like Fig. 3 and shown in Figure 4; Integrated rolling mill axial adjusting device of the present invention, comprise upright column of rolling mill 1, be arranged on the upright column of rolling mill 1 and be used for back-up roll 2 roll chock 3, be inserted into the through hole 5 of upright column of rolling mill 1 button-headed bolt 4, be used for fixing and the integral shaft of adjusting roll chock 3 to pressing plate 6.
Wherein, integral shaft is provided with 3 openings to pressing plate 6, corresponds respectively to three roll chocks 3 of three-roller type steel rolling mill, to be used for fixing respectively or to move and go up the bottom roll bearing block.Integral shaft is formed with 12 oblate hole slots 7 on pressing plate 6, be provided with 4 around each roll chock 3.In the present invention, the best semicircular in shape in the two ends of this oblate hole slot 7, arc radius can be 13mm.
