Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 and fig. 2, the utility model discloses a billet bending machine, including veneer reeling machine body 1, be equipped with first veneer reeling roller 11, second veneer reeling roller 12 and third veneer reeling roller 13 on veneer reeling machine body 1, third veneer reeling roller 13 sets up between first veneer reeling roller 11 and second veneer reeling roller 12 to be located the top at first veneer reeling roller 11 and second veneer reeling roller 12. In order to enable the plate bending machine to meet the bending requirements of steel bars, particularly flat steel, the third plate bending roller 13 is sleeved with a sleeve 14, and an annular bending groove 141 which is coaxial with the sleeve 14 and is matched with the thickness of the steel bars is arranged on the outer surface of the sleeve 14.

The degree of depth of bending over groove 141 can set up wantonly, and the preferred width that is greater than the billet can avoid bending over a slow fire in-process steel bar like this to take place to appear along the condition of its thickness direction bending deformation.

During the bending over a slow fire, put into annular bending over groove 141 with billet 2 in, utilize the height of veneer reeling machine adjustment third roll bending roll 13 to can adjust bending over a slow fire groove 141 and first roll bending roll 11, the distance of second roll bending roll 12, and then adjust bending over radian of billet 2. Start the drive arrangement on the veneer reeling machine body 1, rotate through first veneer reeling roller 11 of drive arrangement drive and second veneer reeling roller 12, can be with billet 2 forward movement, the billet receives the bending machine groove 141 decurrent squeezing action and takes place the bending at the removal in-process to the realization is to the bending machine of billet 2. The utility model discloses a billet bending machine device directly overlaps at third book board roller 13 and establishes sleeve 14 to set up annular bending machine groove 141 on sleeve 14, through bending machine groove 141 and the cooperation of billet 2, can fix the billet, can guarantee that the crooked direction of the especially band steel of billet is at its width direction, has satisfied the bending machine requirement of the especially band steel of billet, and very big billet bending machine efficiency still can save the purchase expense of bending machine equipment.

When the steel strip is not to be hot-bent, the sleeve 14 is removed from the third bending roll 13 and is continuously used for hot bending the sheet.

The sleeve 14 can be fixed on the third plate rolling roller 13 by means of a jacking screw, but the third plate rolling roller 13 is easily damaged, and the subsequent plate rolling of the plate rolling machine is affected. In the embodiment of the present invention, the sleeve 14 is in clearance fit with the third rolling plate roller 13, so as to rotate relative to the third rolling plate roller 13. Therefore, the damage to the third rolling plate roller 13 is small, and the sleeve 14 is more convenient to mount and dismount.

The sleeve 14 can be arbitrarily arranged at the position of the third plate rolling roller 13, but because the plate rolling roller of the plate rolling machine is longer in length, the plate rolling roller is locally stressed when bending a steel bar, and particularly when the third plate rolling roller bends the steel bar, especially a flat steel bar with a larger width, the bending moment of the third plate rolling roller is larger, so that deformation is easy to occur, and the plate rolling effect of the plate rolling machine can be influenced. In order to reduce the bending moment applied to the third rolling roll and prevent the third rolling roll from deforming, as shown in fig. 3, preferably, the sleeve 14 is arranged at one end of the third rolling roll 13 close to the operation side tilting bracket 15 on the rolling machine body 1, one side of the sleeve 14 close to the transmission side bracket 19 on the rolling machine body 1 is provided with a balance mechanism located above the third rolling roll 13 for applying a pressure downward to the third rolling roll 13, and the balance mechanism is located between the operation side tilting bracket 15 and the transmission side bracket 19 and is installed on the installation frame 16 detachably connected with the frame of the rolling machine body 1. Thus, when bending the steel bar, the sleeve 14 is arranged at one end of the third plate rolling roller 13 close to the operation side overturning bracket 15 on the plate rolling machine body 1, the distance from the stress point of the steel bar 2 on the third plate rolling roller 13 to the operation side overturning bracket 15 is short, the bending moment received by one end of the third plate rolling roller 13 close to the operation side overturning bracket 15 on the plate rolling machine body 1 is small, the other end of the third plate rolling roller 13 can provide a downward pressure through a balance mechanism to offset or partially offset the upward force of the steel bar on the third plate rolling roller, so that the bending moment of one end of the third plate rolling roller 13 close to the transmission side bracket 19 can be reduced, and therefore, the deformation of the third plate rolling roller can be prevented. The balance mechanism is arranged on the mounting frame 16 which is detachably connected with the frame of the plate bending machine body 1, so that the balance mechanism is conveniently detached from the plate bending machine after being used without influencing the subsequent plate bending of the plate bending machine. The mounting frame 16 can be detachably connected with the frame of the plate bending machine body 1 by means of bolting, clamping, pin connection and the like.

When setting up balance mechanism, sleeve 14 adopts and the clearance fit of third roll board roller 13 to can be for the pivoted structure of third roll board roller 13, third roll board roller 13 can be rotated by sleeve 14 when bending over a fire and third roll board roller 13 does not take place to rotate, and balance mechanism can not receive the lateral force like this, is more convenient for set up balance mechanism.

The balancing mechanism can be a cylinder, a hydraulic cylinder, a screw rod or the like. As shown in fig. 3, in order to adjust the pressure of the balance mechanism on the third rolling plate roller 13 according to actual conditions, the balance mechanism is preferably a screw 18 vertically arranged above the third rolling plate roller 13, and the screw 18 is in threaded connection with the mounting frame 16. Therefore, the screw 18 is screwed downwards to provide a downward pressure, and the screw 18 is screwed to adjust the pressure. In order to prevent the screw rod 18 from damaging the third rolling plate roller 13, an arc block 17 connected with the screw rod 18 in a rotating way can be arranged at the end part of the screw rod 18 so as to increase the contact area with the third rolling plate roller 13.

Specifically, the simmer bending groove 141 may be formed by directly grooving the outer surface of the sleeve, but this requires a thicker sleeve and is wasteful of material. In order to save materials, as shown in fig. 4, in the present invention, two annular plates 142 are welded to the sleeve 14 at intervals, and the simmer bending groove 141 is formed between the annular plates 142.

As shown in fig. 4, in order to prevent the annular plate from being deformed, a plurality of support ribs 143 are welded to the outer side of the annular plate 142 and spaced along the annular plate 142. In order to make the sleeve 14 be stressed more uniformly and better, the supporting ribs 143 of one of the annular plates 142 are staggered with the supporting ribs 143 of the other annular plate 142.
