Abstract

The utility model discloses a three-roll import rolling guide, which comprises a box body and a holding board and is characterized in that: the inside of the box body is arranged with two lower guide rollers with the same shape whose front and rear parts are arranged parallel; the front part of the box is hinged with the holding board through a connecting shaft; the holding board is arranged with an upper guide roller which is arranged above the two low guide rollers; and the combined images of the appearances of the upper and lower guide rollers are similar to the shape of a rolling matter. A stud is arranged at the back of the box body; a spring is arranged outside the stud; the holding board is arranged with a flute hole which holds the stud and is pressed on the spring; a nut is arranged above the hole on the holding board. The utility model can conveniently regulate the positions of the guide rollers to make the upper and lower guide rollers properly clamping the rolling matter and make the rolling matter being successfully guided into the roll pass of the rolling mill.

Description

Three-roller entrance rolling guide is defended

Technical field

The utility model is a kind of inlet rolling guide device that is used for section bars such as rolling angle iron, channel-section steel in the steel rolling continuous-rolling system.Especially relating to a kind of rolled piece of helping along its length makes it be directed into roll Pass and prevent that the rolled piece surface is by the special-purpose inlet rolling guide device of scratch exactly.

Background technology

Three-roller entrance rolling guide defend device be in the continuous section rolling system before finished product and in finished product sortie rolling with rolled piece accurately guiding enter roll pass and prevent the rolled piece surface by a kind of device of scratch, be mainly used in angle steel, channel-section steel rolling of section configuration complexity.Guarantee the up-to-standard of finished product rolled piece,, rolling parameter coupling correct except roll pass rationally, can rolled piece enter in the roll Pass smoothly and accurately also is crucial.

At present, domestic when above angle steel of rolling 5# and the above channel-section steel of 5#, before finished product, can not select for use because of there being suitable rolling guide, so in the actual production of steel rolling producer, have to adopt import sliding guide device with the required import guide and guards of finished product sortie.Because of the guiding poor accuracy of import sliding guide device, easily scratch rolled piece surface causes production accident many, and the percent defective height has seriously restricted the quality of shaped steel product and the raising of output.

The utility model content

The purpose of this utility model provides a kind of three-roller entrance rolling guide and defends device series, can satisfy domestic at rolling 5#～16# angle steel and the 5#～28# channel-section steel needs to the inlet rolling guide device.

The technical solution of the utility model is as follows:

Three-roller entrance rolling guide is defended, include casing, hold plate, it is characterized in that described box house is equipped with parallel and two lower guide rolls that shape is identical in front and back, casing front end top is equipped with the rotary plate of holding, the inside of holding plate is equipped with one and goes up deflector roll, and last deflector roll is positioned at the centre of two lower guide rolls; The outer table skeleton of upper and lower deflector roll has projection and groove respectively, and the gap shape that forms between projection and the groove is similar to the shape of rolled piece; A double-screw bolt is equipped with in the top, rear portion of casing, and double-screw bolt is with spring outward; The afterbody of holding plate has slotted eye, holds plate and packs into screw rod by this slotted eye and be pressed on the spring, of screw rod nut is installed.

Hold plate and be movably hinged, hold plate and can rotate around bearing pin by bearing pin and casing; The box back top is connected with charging aperture by bearing pin, and charging aperture can rotate around bearing pin.

Be equipped with the water stream channel that upper and lower deflector roll is sprayed water and cooled off at casing on the plate with holding.

Eccentric bushing is equipped with at the two ends of described lower guide roll axle, and eccentric bushing and lower guide roll axle are connected as a single entity with key, and eccentric bushing is installed on the casing.

The primary clustering that three-roller entrance rolling guide is defended device has: casing, hold plate, charging aperture, go up deflector roll, lower guide roll and spring attachment.Hold plate and utilize connecting axle to be connected with casing, hold plate and can rotate around connecting axle, the location of holding Board position is to regulate by a sleeve spring hold down gag at rear portion.Charging aperture utilizes a bearing pin to be connected with casing, and charging aperture also can rotate around bearing pin.Parallel and two lower guide rolls that shape is identical before and after box house is equipped with are held and are equipped with one in the plate and go up deflector roll, at casing and hold all have on the plate on the spray water spray apertures passage of cooling of deflector roll and lower guide roll.

In the time of in working order, last deflector roll is in two tops between the lower guide roll, and the utility model is that the cooperation by such three deflector rolls realizes the clamping to rolled piece.Charging aperture mainly plays the guiding rolled piece and enters this device.

Lower guide roll and last deflector roll are installed on casing respectively by guide roller axis and hold on the plate, and lower guide roll elasticity when rotated can realize with the end play that changes bearing by the nut of rotation deflector roll axle head.Can change the stroke of spring, the inclination angle of holding plate with adjustment by the nut of rotation on the double-screw bolt.Pack into double-screw bolt and be pressed on the spring owing to hold slotted eye on the plate, when screwing nut, the spring pressurized is held plate and is moved down, with on deflector roll also move down, thereby adjust the upper-lower position of going up deflector roll.Elasticity when last deflector roll rotates can realize by the end play of rotation guide roller axis change bearing.

By respectively the adjustment of upper and lower deflector roll being changed clamping gap to rolled piece, two lower guide rolls work the effect of lifting to rolled piece, last deflector roll plays the compacting stabilization to rolled piece, adjust in the gap between the upper and lower deflector roll that rolled piece should neither swing under the suitable situation, also dipping and heaving not, rolled piece could successfully be directed in the roll pass of milling train in this case.

The utility model guide and guards guiding accurately is difficult for scratch rolled piece surface, has improved the quality and the output of shaped steel product.

The specific embodiment

Three-roller entrance rolling guide is defended, include casing 1, hold plate 2, parallel and two lower guide rolls 9 that shape is identical before and after box house is equipped with, casing 1 front upper place is equipped with the rotary plate 2 of holding by connecting axle, holds deflector roll 8 is installed in the plate 2, and last deflector roll is above between two lower guide rolls, the outer table skeleton of upper and lower deflector roll has projection and groove respectively, and the gap shape that forms between projection and the groove is similar to the shape of rolled piece.The back upper place of casing 1 is equipped with double-screw bolt 5, and double-screw bolt 5 is outer to be with spring 4, holds on the plate 2 grooved hole and packs into double-screw bolt 5 and be pressed on the spring, holds on the slotted eye of plate nut is installed.Casing 1 rear end can be rotated around bearing pin with the bearing pin 6 hinged charging apertures 7 that are equipped with, charging aperture.At casing 1 with hold the water spray cooling hole path that is equipped with upper and lower deflector roll on the plate 2.

Lower guide roll 9 is installed on the lower guide roll axle 10, and the two ends of lower guide roll axle are with eccentric flange 11 and eccentric bushing 12, and eccentric flange 11 and eccentric bushing 12 are installed on the casing 1.When adjusting two lower guide rolls, must regulate off-centre, be in same horizontal plane with the axle center that guarantees two lower guide rolls 9 by same orientation.
