Abstract
The invention discloses circular arc rolling equipment for square pipes. The circular arc rolling equipment comprises a sliding sleeve, an upper shaft, a lower shaft and pressing rollers. The lower shaft is fixed to a frame through a bearing. The upper shaft is installed on the sliding sleeve through a bearing. The sliding sleeve controls the upper shaft to move up and down. The pressing rollers are installed at the shaft ends of the same side of the upper shaft and the lower shaft correspondingly. A groove is machined in the outer surface of each pressing roller. The grooves are matched with the widths of the circular-arc-machined square pipes correspondingly. The square pipes are controlled in the pressing rollers correspondingly and rotate along with rotation of the shafts, and thus the purpose that circular arcs are formed on the square pipes in a rolled mode is achieved. Through the circular arc rolling equipment, manual operation can be reduced effectively, and cracks liable to occur due to assembly welding are avoided. The sizes of the machined square pipes with radians are regular, and the radian uniformity is good.
Description
Technical field
The present invention relates to a kind of special equipment of rolling and processing, be specifically related to a kind of square tube circular arc roll unit.
Background technology
When current requirement is processed with the square tube of circular arc, many employings assembling method is processed, and welding processing is carried out to junction, this method expense of not only taking a lot of work is expected, weld is also the stress concentration point of this angled square tube simultaneously, be easy to, because reaching fatigue point by effect of stress for a long time, easily ftracture.
Summary of the invention
For the technical problem of above-mentioned existence, the object of this invention is to provide and a kind ofly can meet converted products requirement simultaneously again easily fast and very durable equipment.
The technical solution used in the present invention is: a kind of square tube circular arc roll unit comprises: sliding sleeve, upper axle, lower shaft, pressure roller.Lower shaft is fixed on the top of the shelf by bearing; Upper axle is arranged on sliding sleeve by bearing, and sliding sleeve controls upper axle and moves up and down; The homonymy axle head of upper axle, lower shaft is provided with pressure roller, and pressure roller outer surface is processed with groove, and the square tube width of this groove and Machining Arc adapts, and square tube is controlled in pressure roller, rotates along with the rotation of axle, thus realizes the object that square tube is rolled into circular arc.
Technique scheme and prior art have the following advantages and beneficial effect:
1. square tube circular arc roll unit effectively can reduce a manual operation, avoids the easy cracking that assembled welding causes.
2. the square tube structured size having radian of square tube circular arc roll unit processing, radian uniformity is good.

Detailed description of the invention
Below in conjunction with Fig. 1, embodiments of the invention are described further: a kind of square tube circular arc roll unit comprises: sliding sleeve (1), upper axle (2), lower shaft (3), pressure roller (4).Lower shaft (3) is fixed on shelf (5) by bearing; Upper axle (2) is arranged on sliding sleeve (1) by bearing, and in sliding sleeve (1) control, axle (2) moves up and down; The homonymy axle head of upper axle (2), lower shaft (3) is provided with pressure roller (4), pressure roller (4) outer surface is processed with groove, the square tube width of this groove and Machining Arc adapts, square tube is controlled in pressure roller (4), rotate along with the rotation of axle, thus realize the object that square tube is rolled into circular arc.
A kind of operation principle of square tube circular arc roll unit is: pressure roller 4 groove width adapts with the square tube width being processed with circular arc, to bring when sliding sleeve 1 moves downward on axle 2 and upper axle 2 that pressure roller 4 is corresponding to be moved downward, thus reduce arc forming radius, and pressure roller 4 relies on the power of motor and gear to rotate on lower shaft 3 and lower shaft 3, thus the roll extrusion action realized square tube, square tube is rolled into by the reciprocating action of this series the circular shape meeting product requirement.
A kind of square tube circular arc roll unit effectively can reduce manual operation, and make the square tube of radian have good intensity, the square tube structured size having radian of processing, radian uniformity is good.
Claims (2)
1. square tube circular arc roll unit comprises: sliding sleeve, upper axle, lower shaft, a pressure roller, is characterized in that: lower shaft is fixed on the top of the shelf by bearing; Upper axle is arranged on sliding sleeve by bearing, and sliding sleeve controls upper axle and moves up and down.
2. a kind of square tube circular arc roll unit according to claim 1, it is characterized in that: the homonymy axle head of upper axle, lower shaft is provided with pressure roller, pressure roller outer surface is processed with groove, the square tube width of this groove and Machining Arc adapts, square tube is controlled in pressure roller, rotate along with the rotation of axle, thus realize the object that square tube is rolled into circular arc.
