fig. 2 is a partial cross-sectional side view of the present invention;

fig. 3 is a top view of the present invention;

fig. 4 is a schematic structural view of the V-shaped carrier roller frame of the present invention.

In the figure: 1. the automatic feeding device comprises a manual screw, 2 nuts, 3 supports, 4 guide sleeves, 5 guide rods, 6 bearing seats, 7 driving rollers, 8 driven rollers, 9V-shaped roller supporting frames, 91 roller shaft grooves, 10 bases, 11 hand cranks and 12 movable supports.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples, and referring to fig. 1 to 4, a three-roller thin-wall pipe coiling machine is provided with a bracket 3 fixed on a base 10, the bracket 3 is made of angle steel, and the lower end thereof is welded with the base 10; the upper end of the bracket 3 is provided with a manual screw 1 with a handle through a nut 2, the lower end of the manual screw 1 is connected with a movable bracket 12, two ends of the movable bracket 12 are welded with a guide sleeve 4 on a guide rod 5, and the lower end of the guide rod 5 is welded with a base 10; a bearing seat 6 is arranged in the middle of the movable support 12, a driving roller 7 is arranged in the bearing seat 6, and a crank 11 is arranged at one end of the driving roller 7; a V-shaped roller carrier 9 is fixed on the upper surface of the base 10 and below the other end of the driving roller 7 in parallel, and roller shaft grooves 91 are symmetrically arranged above the V-shaped roller carrier 9; the symmetrical axis of the V-shaped roller frame 9 is parallel to the axis of the driving roller 7, and the driven roller 8 is arranged in parallel in the symmetrical U-shaped roller groove 91 of the V-shaped roller frame 9.

The utility model discloses a support 3 reciprocates along guide arm 5, and drive roll 7 links as an organic wholely with bearing frame 6, and adjustable drive roll 7 and driven roll 8's upper and lower clearance adapts to the panel of various thickness. When the driving roller 7 is pressed downwards, extrusion force is applied to the plate, the hand crank 11 at one end of the driving roller 7 is rotated to drive the plate to do circular motion, the manual screw 1 is gradually adjusted downwards, and the thin plate is pressed to be in a circular arc shape. The V-shaped roller frame 9 can adjust the horizontal distance according to the diameter requirement of the rolled pipe to finish the rolling of the pipe to the required diameter. Roll up the pipe and take out from the 7 outside ends of drive roll after taking shape, arrange welded joint department, put into again and roll up the system and maintain, can roll up out required standard diameter's thin wall pipe, use the utility model discloses afterwards, the reelpipe is of high quality, alleviates intensity of labour efficient.

The utility model discloses consider the requirement that the atress is big, manual screw 1 adopts trapezoidal screw (trapezoidal thread drive torque is big, long wear life), and manual screw 1's lower extreme and movable support 12 adopt unsteady articulate mode. The driving roller 7 is made of 45# steel. The movable support 12, the bearing seat 6, the guide rod 5, the guide sleeve 4, the hand crank 11, the support 3, the V-shaped roller frame 9 and the bottom plate 10 are made of Q235 steel. The shape of the V-shaped roller carrier 9 is that the pressing stroke of the driving roller 7 is considered to be increased, the driven roller 8 is horizontally adjusted to be placed in a U-shaped groove 91 of the roller shaft groove of the V-shaped roller carrier 9, and the horizontal distance is adjusted, so that thin-walled pipes with various diameters can be rolled to reach the diameter of a rolled circular pipe.
