Abstract

The utility model discloses an adjusting device for the axis distance of a guide roll for rolling guides and guards. The utility model has simple structure and convenient adjustment, is suitable for multiform installation and can keep the axis distance of the adjusted guide roll stable. A locating mechanism limiting the change of the distance between the guide rolls is added on a box body in the prior art. The position between the arms of the guide rolls can be adjusted by an adjusting screw in an adjustment mechanism when the utility model is installed in a lateral type or a horizontal type and can be positioned by a spring arranged between the two arms of the guide rolls. Consequently, the phenomenon of dropping the arms of the guide rolls is avoided, and the defect that the guide rolls are knocked frequently to be damaged when a guiding guard in the prior art is installed in a lateral type is overcome.

Description

The guide roller axis spacing regulator of rolling guide

Technical field

The utility model discloses the servicing unit that is used for drawn and rolled tube in a kind of metallurgy industry steel rolling continuous-rolling system, specifically is the guiding roll axes spacing regulator of the rolling guide that uses in a kind of tube rolling process.

Technical background

At present, the structure of the rolling guide that uses in the prior art as shown in Figure 1, Fig. 1 is the vertical view of 0930 type rolling guide, a left side of installing on the casing 7, right deflector roll arm 1, the deflector roll 8 of 2 front ends, wheelbase between 9 relies on adjustment cam 6 and is adjusted by screw 5, be positioned at deflector roll arm fulcrum shaft 4 and deflector roll 8, left side between 9, right deflector roll arm 1, be provided with support spring 3 between 2, because this guide and guards is applicable to vertical installation in the prior art, it is deflector roll 8,9, a left side, right deflector roll arm 1,2 the surface of revolution and spring 3 are positioned at horizontal plane, the elastic force of spring 3 is with a left side, right deflector roll arm 1,2 push open laterally along horizontal plane, screw 5 and adjustment cam 6 are kept in touch, support spring 3 is limit because of being subjected to structure, size is less, operating pressure only can satisfy and overcome deflector roll arm fulcrum shaft 4 and deflector roll arm 1, frictional force between 2, the prior art can keep deflector roll 8 under above-mentioned vertical installment state, wheelbase between 9 makes it can operate as normal.

In modifying rolling mill or new designing apparatus, usually roller (guide) apron must adopt side formula mounting means, promptly two deflector roll arms are in the upper-lower position state, because the deadweight that is in the deflector roll arm on top surpasses the operating pressure of support spring, last deflector roll arm will arm phenomenon occur falling usually, and adjusted deflector roll spacing arm is diminished, and when crossing steel serious impingement phenomenon will take place, cause deflector roll arm frequent breakage, can't operate as normal.

Technology contents

The purpose of this utility model be to provide a kind of simple in structure, easy to adjust and be suitable for that various ways is installed and the guiding roll axes that keeps the stable rolling guide of adjusted deflector roll spacing apart from adjusting device.

For achieving the above object, the technical solution adopted in the utility model is: the guide roller axis spacing regulator of rolling guide, by deflector roll arm fulcrum shaft is hinged the deflector roll arm arranged on the casing, the front end of deflector roll arm is provided with deflector roll, the tail end position of deflector roll arm is provided with the guiding mechanism of the deflector roll spacing of adjusting screw and the formation of cam between the two, it is characterized in that: be connected with extension spring between two deflector roll arms, this extension spring is positioned at two deflector roll arm tail ends, one side.

As shown from the above technical solution, substantially do not changing on the basis of original technical pattern, only adding the detent mechanism that spacing changes between the restriction deflector roll on its casing, make it when side formula, horizontal installation, all can adjust the deflector roll arm by the adjustment screw in the guiding mechanism, the extension spring location that position through adjusting is provided with between by two deflector roll arms, thus the arm phenomenon of falling of deflector roll arm avoided, and then overcome the defective of guide and guards of the prior art frequent breakage deflector roll when the side formula is installed.

The specific embodiment

Embodiment.

Referring to Fig. 2,3, the guiding roll axes of rolling guide is apart from adjusting device, by deflector roll arm fulcrum shaft is hinged deflector roll arm 20 arranged on the

casing

10,30, be positioned at the deflector roll arm 20 on the deflector roll arm fulcrum shaft, an end of 30 is respectively equipped with deflector roll, said structure can be referring to the prior art constructions among Fig. 1, deflector roll arm 20,30 the other end is provided with adjusts screw 40, the guiding mechanism of the 50 deflector roll spacings that constitute with between the two cam 60, cam 60 is fixed on the casing 10, two deflector roll arms 20 of this end, be connected with extension spring 70 between 30, the pulling force effect of extension spring 70 is with deflector roll arm 20,30 draw over to one's side, and guarantee to adjust screw 40,50 contact with the stable of cam 60, make deflector roll arm 20 simultaneously, the deflector roll fixation that is provided with on 30 is in suitable spacing position.Suitably rotating cam 60 turns over suitable angle, because cam 60 will make deflector roll arm 20,30 rotate around its deflector roll arm fulcrum shaft with the abutment action of adjusting screw 40,50, because the effect of extension spring 70, the distance adjustment between deflector roll is kept.In the prior art owing to many-sided reason, deflector roll arm fulcrum shaft is apart from deflector roll and adjust screw 40,50 between the two distances do not wait, the distance of deflector roll arm fulcrum shaft and deflector roll is significantly less than deflector roll arm fulcrum shaft and adjusts screw 40,50 between the two distances, the two ends of adding extension spring 70 are fixed on deflector roll arm 20, on the spiral pin 80 that 30 tail ends are provided with, above-mentioned deflector roll arm 20,30 is parallel to each other with the centre of gyration of deflector roll, this just makes extension spring 70 apart from deflector roll arm fulcrum shaft sufficiently long distance be arranged, as long as the tensile strength of extension spring 70 is suitably, be convenient to obtain the stable maintenance of deflector roll spacing, this scenario-frame is simple and reliable.
