Technical field
The present invention relates to technical field of metal formation, and in particular to a kind of sheet material rolls apparatus for bending.
Background technology
Sheet metal rolling bender is the equipment that Bending Processing is carried out to metal blank, and it includes two supporting plates and turned Dynamic multigroup format roll in two supporting plates.The upper roller and bottom roll for including being oppositely arranged per composing type roller, upper rolling Cylinder and bottom roll are provided with the folding surface being used cooperatively, with to carrying out bending work by the sheet material between upper roller and bottom roll Industry.Each upper roller is connected by a screw rod with supporting plate, stretching or the upper roller of the regulation that retracts and bottom roll by screw rod The distance between, to adapt to the bending operation of the sheet material of different-thickness.However, the sheet material rolling bender of prior art, its spiral shell The stretching of bar or the bad control of the distance of rollback, easily cause the distance between upper roller and bottom roll of every composing type roller no Deng so as to influence the precision of sheet metal bending.
The content of the invention
For above-mentioned problem, it is necessary to provide a kind of sheet material rolling bending that can improve sheet metal bending precision Machine.
To achieve these goals, the technical solution adopted by the present invention is as follows:
A kind of sheet material rolls bender, for 90 ° of sheet metal bending, the sheet material rolling bender to be included into what is be oppositely arranged Two supporting walls and the multigroup format roll laid along the direction of transfer interval of a sheet material, include vertically phase per composing type roller To the upper roller and bottom roll of setting, each supporting walls include supporting plate and some sliding blocks, are interval with the supporting plate more Individual chute, the sliding block are slidably installed in corresponding chute, and the sheet material rolling bender also includes several regulation spiral shells Bar, each adjusting screw rod are bolted in corresponding supporting plate and connected with corresponding sliding block, and the adjusting screw rod can be in external force In the presence of rotate to drive the sliding block vertically moving, at least side of the chute is provided with scale, the mark Chi is installed on corresponding body, to measure the position of the sliding block in the vertical direction, the upper roller and the bottom roll Include the cylinder body of telescopic shaft and fixed cover on the telescopic shaft, the opposite end point of the telescopic shaft of the upper roller It is not installed in rotationally on the sliding block of described two supporting walls, the opposite end of the telescopic shaft of the bottom roll rotationally fills respectively In described two supporting plates and positioned at the lower section of the chute, the rolling of the cylinder body and the bottom roll of the upper roller Cylinder main body is correspondingly provided with the folding surface being used cooperatively, and the sheet material rolling bender also includes base, screw mandrel drive mechanism and company Bar, one of supporting plate are fixed on the base, and another supporting plate is movably arranged on the base, the screw mandrel driving Mechanism includes screw mandrel, the driving screw mandrel motor rotated and the feed screw nut being bolted on the screw mandrel, the connecting rod connection The feed screw nut and the supporting plate of activity installing, make it that described two supporting walls are close to each other or are located remotely from each other.
Further, the magnitude range for the angulation that the folding surface and a shaping roll axis are formed is 0 ° -90 °, and described Direction of transfer of the size of the angulation of multigroup format roll along the sheet material is gradually increased to 90 °.
Further, each supporting plate includes body and several lids, and the chute sets on the body and had One opening, lid installing on the body and are covered in the opening of respective slide slots, the adjusting screw rod with it is corresponding Lid screws togather, and wears corresponding lid to be connected with corresponding sliding block, the opposite end difference of the telescopic shaft of the bottom roll It is installed on the body of described two supporting plates and is located at the one end of the chute away from the opening.
Further, the side wall for surrounding the chute is provided with the guidance part that vertically extends, right on the sliding block Guide part should be provided with, the guidance part is slidably matched with the guide part, with the motion guide to sliding block.
Further, one of the guidance part and the guide part are groove, and another pair should be set to protruding rail, described convex Rail is slidably contained in the groove.
Further, the sheet material rolling bender also includes the multiple limits laid along the direction of transfer interval of the sheet material Position mechanism, each position-limit mechanism include two locating parts being installed in respectively in described two supporting plates, and each locating part is located at Between two adjacent composing type rollers, each locating part includes screw rod, mounting bracket and limited roller, and the screw rod is bolted in accordingly In supporting plate, the mounting bracket is installed on the screw rod and between described two supporting plates, and the limited roller rotates Ground is installed on the mounting bracket.
Further, the perisporium of the limited roller is concavely provided with stopper slot.
Due to using above-mentioned technical proposal, the invention has the advantages that:
1st, sheet material of the invention rolling bender, upper roller are movably connected with corresponding supporting walls by a sliding block, Adjusting screw rod is bolted on corresponding supporting walls and is connected with sliding block, and the stretching of adjusting screw rod or rollback can drive roller to lean on Nearly bottom roll or remote bottom roll, to realize that upper spacing between roller and bottom roll is adjustable, so as to adapt to different-thickness sheet material Bending operation.Meanwhile sheet material rolling bender of the invention is also provided with scale at least side of chute, to measure sliding block The position of in the vertical direction, to ensure that the regulated quantity of the upper roller on same supporting walls is consistent, and then sheet material can be improved Machining accuracy.
2nd, sheet material of the invention rolling bender, one of supporting walls be actively installed on base and by connecting rod with Screw mandrel drive mechanism connects, by the cooperation of screw mandrel and nut, make it that described two supporting walls are close to each other or remote, simultaneously Coordinate the stretching motion of format roll telescopic shaft, so that the distance between two supporting walls are adjustable, to adapt to different in width The bending operation of sheet material, it is easy to use.
3rd, sheet material of the invention rolling bender, sheet material to be bent pass sequentially through format roll under the transmission of transport mechanism Carry out rolling bending.Due to format roll be provided with it is multigroup, and the folding surface of multigroup format roll with shaping roll axis formed angulation edge The direction of transfer of sheet material gradually increases, therefore, one less angle of bending when the sheet material bent often passes through a composing type roller, The bending angle of sheet material is become larger until reaching the predetermined angular of bending needed for sheet material after multigroup format roll.Due to this hair Bright sheet material rolling bender bending sheets by the way of continuous several times roll bending, therefore the deformation that can reduce sheet material is returned Bullet, to ensure that sheet metal bending has higher precision after being molded, improve the molding effect of sheet material.
4th, sheet material of the invention rolls bender, and interval is equiped with multiple position-limit mechanisms on each supporting walls.Each limit Position mechanism includes two locating parts being divided on two supporting walls.Each locating part includes screw rod, mounting bracket and limited roller. During bending operation, the perisporium of the limited roller of two locating parts abuts with the opposite sides of sheet material, so as to be positioned to sheet material, Further increase the machining accuracy of sheet material.
