Abstract
A multifunctional roller device comprises two rollers mounted on two sliders respectively. The multifunctional roller device is characterized in that the two rollers incline upwards and downwards for 6 degrees to 10 degrees relative to the horizontal plane, and the distance between the two sliders can be adjusted through an adjusting structure. According to the multifunctional roller device, three rollers are simplified to be two rollers, so that the distance between the two sliders can be adjusted conveniently, and seamless steel tubes of different specifications can be produced; simultaneously, as for the design of the inclined angles of the two rollers, pre-tightening force and tube forming factors are considered comprehensively; and by means of the design of a guide sleeve, the raw material position can be guaranteed, and the offset is prevented.
Description
Technical field
The utility model relates to the roll seamless steel tube technical field, specifically a kind of Multifunctional roll device.
Background technology
In general, the roll in mill of seamless steel tube machine or the punch all is that three pairings are used, and three rollers are isosceles triangle to be arranged, comes rolling.The arrangement form of the roll in the finishing mill of for example announcing in the Chinese patent 200720091705 just belongs to this situation, and the finishing mill of this three-roller type has following shortcoming:
Need higher installation accuracy, three rollers uniformly layout just can reach the effect of use, the while in general the position between three rollers all be well-determined, can only produce a kind of seamless steel pipe of specification.
The utility model content
The purpose of this utility model is to provide a kind of Multifunctional roll device, is a kind of double roller structure, and convenient the installation has convenient function of regulating simultaneously.
The technical scheme in the invention for solving the technical problem is: a kind of Multifunctional roll device, comprise two rolls, be installed in respectively on two slide blocks, it is characterized in that, two rolls respectively relative level are spent to 10 degree angles with downward-sloping 6 facing up, and the spacing of two slide blocks can be regulated by adjustment structure.
Described two slide blocks respectively relative level are spent angles with downward-sloping 8 facing up.
Be provided with a circular guide pin bushing in the front portion of two rolls.
Described adjustment structure is line slide rail.
Shown in roll be middle thick drum type, and the tapering of front end is 5 degree, the tapering of rear end is 1 degree.
The beneficial effects of the utility model are: the roll in the utility model has three to be reduced to two, can regulate more easily the spacing of two rolls, produces the seamless steel pipe of different size.The factor of pretension dynamics and tube forming has been considered in the simultaneously design synthesis at the angle of inclination of two rolls, and the design of guide pin bushing can guarantee raw-material position, prevents skew.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the A--A cutaway view among Fig. 1;
Fig. 3 is the space layout drawing of roll;
Fig. 4 is the cutaway view of roll;
Among the figure: 1 roll, 2 slide blocks, 3 leading screws are regulated, 4 circular guide pin bushings.
The specific embodiment
Such as Fig. 1～shown in Figure 4,
A kind of Multifunctional roll device, the roll 1 in this device comprises two, is divided into left and right sides roll, and roll is split-type design, is installed on the milling train by rotating shaft, and rotating shaft has motor-driven by universal joint.Two roll 1 arranged crosswise are divided into left and right sides slide block on two slide blocks 2, two rolls respectively relative level are spent angles (α angle) with downward-sloping 8 facing up, form the form of intersecting.The pattern of roll wherein as shown in Figure 3, this roll 1 is cydariform, and is middle larger than the diameter at two ends, and the tapering at two ends also has difference, wherein the tapering of an end is larger.Be convenient to like this nipping of plug blank material, form the angle of nipping, wherein the tapering of front end is about 5 degree (β angle), and the tapering of rear end is about 1 degree (γ angle).
The spacing of two slide blocks 2 can be regulated, slip forms by line slide rail, this adjusting is regulated 3 mechanisms by leading screw and is finished, guide screw movement spare is installed between slide block and milling train to be got final product, motor-driven is arranged, can regulate the spacing between two rolls easily, adapt to the manufacturing of the seamless steel pipe of different size requirement.
For preventing the skew of plug, be provided with a circular guide pin bushing 4 in the front portion of two rolls, so just can be so that plug be in position placed in the middle.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
