Background technology
The most employing of rolling line adjusting device in the cold rolling production line of present four rollers adds cushion block and the traditional type wedge is adjusted.The shortcoming that adds cushion block is operation inconvenience, can only quantitatively adjust and to talk about degree automatically low; The shortcoming of traditional type wedge is that structure is extremely complicated, and weight is big, the cost height, and inconvenience is installed, uses, safeguarded to poor rigidity.Working roll and backing roll must cause the variation of rolling production line because of wearing and tearing in the cold rolling production line of four rollers, therefore rolling line adjusting device is one of essential important component in the rolling production line, and urgent need will design the instructions for use that a kind of novel rolling line adjusting device satisfies modern milling train.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Wedge universal stepless rolling line adjusting device and method for designing, designed stepless rolling line adjusting device is simple in structure, compact, performance safety, reliable, in light weight, cost is low, good rigidly, adjustment amount are big, easy to maintenance.
In order to address the above problem, technical scheme of the present invention is: a kind of method for designing of Wedge universal stepless rolling line adjusting device, it is characterized in that: it is designed to left-right turning screw rod with two output shafts of worm type of reduction gearing, the left and right sides Wedge type slide block that drives symmetrical structure by left and right sides spin nut moves horizontally, and drives the purpose that the upper support roll bearing seat realizes that the rolling line universal stepless is adjusted by ball ring simultaneously.
Wedge universal stepless rolling line adjusting device according to this method design, it comprises frame, worm type of reduction gearing, hydraulic motor, encoder, upper support roll bearing seat, it is characterized in that: its worm type of reduction gearing is a dual input dual output structure, worm type of reduction gearing is fixed on the connection crossbeam of two frames, power shaft worm screw one end and hydraulic motor join, the other end and encoder join, and output shaft is a left-right turning screw rod; Left-right turning screw rod spins with left and right sides spin nut screw thread respectively, and left and right sides spin nut is embedded in respectively in the vertical T type groove of Wedge type slide block, and the fixing wedge slide block of going up is fixed on the frame entablature, and the Wedge type slide block is connected by T type groove with fixing going up between the wedge slide block; Ball ring is arranged between Wedge type slide block and the upper support roll bearing seat, and the left and right sides Wedge type slide block of left and right sides spin nut drive symmetrical structure drives the upper support roll bearing seat by ball ring when moving horizontally and moves up and down.
Described ball ring is that the cancave cambered surface by concave spherical surface is pressed on the convex globoidal of protruding sphere and constitutes; Protruding sphere is in box body, and its lower surface is pressed in garden cylindricality box bottom, and cylindricality box body upper surface, garden is connected with two halves garden pressing plate, and two halves garden pressing plate is embedded in respectively in the garden annular groove of concave spherical surface, and whole ball ring is fused.
Characteristics of the present invention are: because this method for designing is changed system into left-right turning screw rod 4 with the output optical axis of known worm type of reduction gearing, save shaft coupling by left and right sides spin nut 5, directly drive the Wedge type slide block and move horizontally, simplify the structure.The left and right sides Wedge type slide block 3 that left and right sides spin nut 5 drives symmetrical structure moves horizontally, and drives the upper support roll bearing seat by ball ring then, realizes the purpose that the rolling line universal stepless is adjusted.Design this Wedge universal stepless rolling line adjusting device, have simple in structure, compact, performance safety, reliable, in light weight, cost is low, good rigidly, advantage that adjustment amount is big, easy to maintenance.
Description of drawings
The present invention is further detailed explanation with concrete mode below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the example structure schematic diagram.
Fig. 2 is the ball ring structural representation.
Among the figure: 1, frame; 2, the fixing wedge slide block of going up; 3, Wedge type slide block; 4, left-right turning screw rod; 5, left and right sides spin nut; 6, worm type of reduction gearing; 7, hydraulic motor; 8, encoder; 9, ball ring; 9-1, concave spherical surface 9-2, protruding sphere 9-3, box body; 9-4, pressing plate; 10, upper support roll bearing seat.
The specific embodiment
Embodiment as shown in Figure 1, critical piece comprises frame 1, fixing wedge slide block 2, Wedge type slide block 3, left-right turning screw rod 4, left and right sides spin nut 5, worm type of reduction gearing 6, hydraulic motor 7, encoder 8, ball ring 9, the upper support roll bearing seat 10 of going up.It is the left-right symmetry structure, its worm type of reduction gearing 6 is dual input dual output structure, be installed on the connection crossbeam of two frames 1, power shaft worm screw one end and hydraulic motor 7 join, the other end and encoder 8 join, worm type of reduction gearing 6 is changed system into output optical axis left-right turning screw rod 4 on the basis of known technology, left-right turning screw rod 4 spins with left and right sides spin nut 5 screw threads respectively, left and right sides spin nut 5 is embedded in respectively in the vertical T type groove of Wedge type slide block 3, the fixing wedge slide block 2 of going up is fixed on frame 1 entablature, and Wedge type slide block 3 is connected by T type groove with fixing going up between the wedge slide block 2; Ball ring 9 is arranged between Wedge type slide block 3 and the upper support roll bearing seat 10, drives upper support roll bearing seat 10 by ball ring 9 when the left and right sides Wedge type slide block 3 that left and right sides spin nut 5 drives symmetrical structure moves horizontally and moves up and down.Ball ring 9 is placed in upper support roll bearing seat 10 arc-shaped holes and left and right sides spin nut 5 plane contact.
