Abstract

The utility model discloses a three-roller reeling machine, comprising a hydraulic pressure station, a table-shape frame, a motor fixed under the frame, a top roller on the three taper-degree bowls set on the table-shape frame as a shape like a Chinese character ''pin'', a lower roller. The compaction devices of the top-roller big-end and of the top-roller small-end are respectively set at the two ends of the top roller. The top-roller big-end compaction device joins the rotation axis of the big-end. The pressing-head of the top-roller small-end compaction is set above the rotation axis of the top-roller small-end. The two lower rollers are installed on the same base, easy to remove and change the three rollers of the three-roller reeling machine and changing the different taper-roller can produce the roller of different taper-degree, reducing the re-investment of the traditional three-roller reeling machine.

Description

Three roller furling plate round machine

Technical field the utility model relates to a kind of furling plate round machine, particularly a kind of three roller furling plate round machine.

Background technology thin plate awl tube moulding process has punch forming and roll bending moulding on principle, wherein punch forming process has two kinds: press U-flat-volume circle, the equipment that uses is punch press; Roll bending moulding process: blanking---volume circle.The equipment of roll bending moulding has two roller furling plate round machine and three rollers (comprising more than three rollers) furling plate round machine.The thin plate of punch forming process awl tube shaped article is second-rate, and the awl tube easily forms a polygon, and secondly punch forming operation is more, and its advantage is to produce the product of different taperings by mold exchange more; Two roller furling plate round machine thin plates awl tube shaped article is second-rate, and its initial period easily forms straightway, produces the product of different taperings and need bore the different furling plate round machine of a tapering; The tube moulding of common three roller furling plate round machine thin plates awl is because three rollers are metallic roll, so the roll bending Forming Quality is better, but the product of different taperings can not realize that the product of producing different taperings needs the different furling plate round machine of roller tapering by changing frock.

The summary of the invention the purpose of this utility model is exactly at the deficiencies in the prior art, and it is convenient to provide a kind of cylinder to change, and can produce three roller furling plate round machine of different tapering awl tubes.

The technical solution of the utility model is as follows: a kind of three roller furling plate round machine, comprise Hydraulic Station, table-shape frame, be fixed in motor below the frame, be isosceles triangle and be installed in three tapering cylinder upper rollers on the table-shape frame, lower roller is respectively equipped with the big end hold-down mechanism of top roll, top roll small end hold-down mechanism at the two ends of described upper roller; The big end hold-down mechanism of top roll is connected with big end turning cylinder; The pressure head of top roll small end hold-down mechanism is positioned at the top of top roll small end turning cylinder; Two lower rollers are installed on the same pedestal.Upper roller is changed easy, and two lower rollers are installed on the same pedestal, change easier.

The tapering of described upper roller is tapering 0.5-1.5 a times of lower roller.Upper roller both can be identical with the tapering of lower roller also can be different with the tapering of lower roller.

The portal trestle of the big end hold-down mechanism of described top roll is fixed on the table-shape frame, across on the big end turning cylinder of top roll, the central shaft hole that big end turning cylinder penetrates Deflector block is slidingly matched, the left and right sides of Deflector block is respectively equipped with turning cylinder, is slidingly matched with the axis hole of the left and right sides fixed head of Deflector block fixed mount; The upper plate of Deflector block fixed mount is fixedlyed connected with the hydraulic column that passes the portal trestle upper plate; Hydraulic cylinder is fixed on the upper plate of portal trestle, holds the tailing screw flight of turning cylinder to cooperate with nut greatly, will hold turning cylinder to be connected with the fixed deflection piece greatly.Deflector block can be done rotation perpendicular to this axis with the axis of big end turning cylinder, to adapt to the roller of different taperings.

Be fitted with bearing in the central shaft hole of described Deflector block, hold turning cylinder to be fitted in the axis hole of bearing greatly.

Described top roll small end hold-down mechanism is by the fixed support that is fixedly connected on the table-shape frame, be fixedly connected on top roll small end one side, support bracket fastened top is connected with L bracket by passing support bracket fastened bolt, its top is fixedly connected with hydraulic cylinder, the hydraulic column of hydraulic cylinder is fixedlyed connected with pressure head, and pressure head and the corresponding position of top roll small end turning cylinder are provided with the circular arc depression.It is promptly rotatable to unclamp bolt L-shaped support, makes pressure head perpendicular to last roll axis, and the hydraulic column of hydraulic cylinder drives pressure head is pressed on the small end turning cylinder circular arc depression, and it is better that circular arc depression and top roll small end turning cylinder are fitted, the level and smooth rotation.The duty of top roll small end hold-down mechanism of tighting a bolt after adjusting both was fixed.

It is the circular arc through hole in the center of circle that the fixed support of described top roll small end hold-down mechanism is provided with the bolt, and bolt passes the circular arc through hole and is connected with L bracket.L bracket is promptly rotatable, and is fixing more firm.

Three rollers of three roller furling plate round machine of the present utility model change conveniently, and the different awl of conversion roller can be processed the awl tube of different taperings, has reduced the overlapping investment of traditional three roller furling plate round machine.
