Abstract

The invention discloses a plate bending mechanism based on extensible bending rods. The plate bending mechanism comprises a support, a lower rotating table, an upper rotating table, a bending baffle and a motor, wherein the lower rotating table and the upper rotating table are in shaft connection with the support, the bending baffle is fixed with the support and located between the lower rotating table and the upper rotating table, and the motor is installed on the support and drives the lower rotating table and the upper rotating table to rotate. The bending rods are arranged on two sides of the bending baffle, and a driving mechanism driving the bending rods to extend is installed on the lower rotating table or the upper rotating table. Bending is achieved through two bending rods which are extensible freely, and due to the fact that the bending rod on one side not needing bending can be retracted, the problem of bending interference is solved. In addition, the bending rods can be arranged to be closer to the bending baffle, so that the bending torsion generated by the motor with the same power is larger. Meanwhile, the contact distance between the plate bending mechanism and a plate can be shortened in the bending process due to reduction of a bending radius, surface scratch is effectively reduced, and accordingly low-scratch, low-interference and efficient bending is achieved.

[0013] 作为优选,所述的下旋转台和上旋转台上设有供折弯棒通过的通孔。 [0013] Advantageously, the lower turntable and an upper turntable provided with holes for passing the bent rod. 因此,折弯挡板两侧的折弯棒伸出时,直接穿过下旋转台和上旋转台,保证了折弯棒的固定强度,从而容易将板材折弯,保证折弯效果。 Accordingly, when the bending rod is bent flap projecting on both sides, and under the turntable on the turntable directly through, to ensure that the bent rod fixing strength, thereby easily bending a plate material, the bending effect is guaranteed.

[0014] 所述折弯棒可布置在下旋转台和上旋转台的外缘或者下旋转台和上旋转台的内部区域,由于材料折弯过程中是靠电机扭力来对抗材料变形时所产生的力,因而力臂大,同样的材料变形所产生的扭矩就大,需要电机的功率就大,作为优选,所述折弯棒靠近所述折弯挡板的板材出口,使得等效的折弯半径可以大大减小,使得同等功率的电机产生的折弯扭力更大。 [0014] The rod may be arranged folded outer edge of the turntable and the lower turntable rotation of the inner region of the upper or lower table and an upper turntable, since the material during the bending by the motor torque is generated against the deformation of the material force, and thus the large arm, the torque produced by the same deformable material is large, the large power requirements on the motor, as is preferred, the bending of the bending rod close to an outlet baffle plate, so that the equivalent bending the radius can be greatly reduced, so that the same motor power greater bending torque generated.

[0016] 驱动机构具体可选用多种形式,作为优选,所述的驱动机构为气缸,结构简单,使用方便。 [0016] DETAILED drive mechanism can be selected in various forms, as is preferred, the drive mechanism is a cylinder, the structure is simple, easy to use.

[0017] 作为优选,所述驱动机构固定设置在下旋转台上,使得折弯棒从下旋转台伸出,由于折弯挡板中间的板材受重力影响,会顺势落在下旋转台上,下旋转台提供一个支撑面,因而,将驱动机构固定设置在下旋转台上,方便折弯。 [0017] Advantageously, the drive mechanism is fixed the lower rotary table, so that the bent rods protrude from the lower turntable, since the intermediate baffle plate is bent by gravity, it will fall under the homeopathic turntable, rotating providing a support table surface, and thus, the driving mechanism is fixed to the lower rotary table, to facilitate bending.

[0018] 下旋转台和上旋转台通过电机驱动,有两种优选的形式,一种是,所述的下旋转台和上旋转台通过连接件固定连接,所述的电机为一台,该电机通过减速机与下旋转台或者上旋转台齿轮配合,从而带动下旋转台、上旋转台、连接件、折弯棒和驱动机构一起转动,通过一台电机和一台减速机就可以达到板材折弯的目的,容易控制。 Rotation [0018] of the rotary table and an upper table by a motor drive, there are two preferred forms, one is the lower turntable and the turntable is fixedly connected by the connection member, according to a motor, which through the motor reducer and the rotary table or gear fitted on the rotating table, so as to drive the turntable, the turntable is rotated together with the connecting member, and the bent rod drive mechanism, through a motor reducer and a sheet can be achieved the purpose of bending, easy to control. 更进一步优选,所述的电机通过减速机与上旋转台齿轮配合,所述的驱动机构固定设置在下旋转台上,分别合理布置在上旋转台和下旋转台上,使得本发明基于伸缩折弯棒的板材折弯机构,结构更紧凑,使用更方便。 Still further preferably, the motor with the gear through the gear on the rotary table, said driving means fixed to the lower rotary table, respectively, and a rational arrangement on the turntable the turntable, so that the present invention is based on a telescopic folding rod plate folding means, more compact, easier to use.

[0019] 另一种是,所述的电机为二台,每台电机通过各自的减速机与上旋转台或下旋转台齿轮配合,且上旋转台和下旋转台同步旋转。 [0019] Another is that the motor is two sets, each motor by the turntable and the turntable with a gear reducer or the respective lower and upper rotary table and rotating table rotated synchronously. 通过同步驱动的方式,可以避免板材折弯过程中连接件的干扰影响,上旋转台、下旋转台各自固定,上旋转台和下旋转台通过电机进行同步驱动,真正实现无干涉死区的折弯过程,折弯效果更好。 By way of synchronous drive, to avoid interference of the connector plate during the bending, on a rotary table, each rotating table is fixed, the turntable and the turntable is driven by synchronized motors, the real off without interference dead zone bending process, bending better.

[0020] 与现有技术相比,本发明具有如下优点: [0020] Compared with the prior art, the present invention has the following advantages:

[0021] 本发明将圆弧形折弯件旋转的折弯方式改为通过两根可自由伸缩的折弯棒实现折弯,由于不需要折弯的一侧的折弯棒可以收缩回去,因而在折弯过程中可以避免现有的板材折弯机构中由于圆弧形折弯件的存在所导致的折弯干涉问题。 [0021] The present invention will be folded arcuate manner to achieve bent parts bent by rotating two free expansion rod is bent, since the bending does not need to bend the rod side may shrink back, thus folding sheet to avoid the conventional bending mechanism due to the presence of the arc-shaped bent parts resulting in interference problems during the bending. 此外折弯棒可以布置的离折弯挡板的距离更近,也就是等效的折弯半径可以大大减小,使得同等功率的电机产生的折弯扭力更大,便于折弯厚的不锈钢板材。 Further bending of the rod can be disposed closer from the folded flap, which is equivalent bend radius can be greatly reduced, so that the same motor power greater bending torque generated, to facilitate bending thick stainless steel sheet . 同时,折弯半径的减小还可以减小折弯过程中板材折弯机构和板材的接触距离,从而有效地降低表面划伤。 At the same time, reducing the bending radius of the contact distance also reduces the sheet during the bending and the sheet folding mechanism, thus effectively reducing the surface scratches.
