The difference is that the bending region 201 is differently provided, and thus, the distance between the plurality of bending columns 225 may be changed to adjust the bending region 201, or the bending stage 223 having a different bending region 201 may be replaced. Furthermore, during the bending process, the corresponding bending table 224 needs to be provided, and during the adjustment of the bending region 201, the bending table 224 needs to be adjusted or replaced so that the structure of the bending table 224 can be adapted to the bending region 201.
The limiting assembly 230 comprises a limiting table 231, a first abutting part 232, a second abutting part 233 and a third abutting part 234; the limit table 231 is movably connected with the main frame body 210, the limit table 231 is used for being clamped with the first rotary table 221 so as to limit the rotation of the first rotary table 221 relative to the main frame body 210, and the limit table 231 can move relative to the main frame body 210 along the central axis of the first rotary table 221 under the action of external force so as to be separated from the clamping connection with the first rotary table 221; the first abutting portion 232 is connected to the obtained second turntable 222, the second abutting portion 233 is detachably connected to the limit table 231, and the third abutting portion 234 is detachably connected to the second turntable 222 or the limit table 231; the first contact portion 232 is configured to contact the second contact portion 233 to drive the stopper 231 to move relative to the main frame 210 along the central axis of the first turntable 221, so that the stopper 231 is disengaged from the first turntable 221; the first abutting portion 232 is configured to abut against the third abutting portion 234 to drive the first turntable 221 to move along its axis relative to the main frame 210, so that the to-be-bent piece located in the bending region 201 is separated from the plurality of bending columns 225;
the power assembly 240 includes a rotating motor, and the rotating motor is used for driving the second rotary table 222 to rotate so as to drive the abutting column 226 connected with the second rotary table 222 to rotate, so as to bend the to-be-bent piece located in the bending region 201, and along the rotating direction of the first rotary table 221, the first abutting portion 232 abuts against the second abutting portion 233 and the third abutting portion 234 in sequence.
In summary, in the process of bending, the efficient bending machine 200 adopts a manner that the second turntable 222 rotates relative to the first turntable 221, and bends a to-be-bent piece which is located in the bending region 201 and abuts against the plurality of bending columns 225 and abuts against the abutment column 226, in the process, the current bending piece extends into the bending region 201 to abut against the plurality of bending columns 225, the position abutting against the abutment column 226 is a processing initial position, the position is a position where bending in the processing process is zero degrees, and subsequently, an angle of rotation of the second turntable 222 relative to the first turntable 221 is a bending angle. Based on this, when the second rotary table 222 rotates to the position where the first abutting portion 232 abuts against the second abutting portion 233, the second rotary table 222 moves continuously along the same rotation direction, and the limiting table 231 is driven to move, so that the rotation limiting effect of the limiting table 231 and the first rotary table 221 disappears, that is, the rotation of the second rotary table 222 after the first abutting portion 232 abuts against the second abutting portion 233 drives the first rotary table 221 to rotate synchronously, and the rotation of the second rotary table 222 does not have the effect of bending the to-be-bent piece. Thus, the bending angle of the high-efficiency bending machine 200 can be adjusted by adjusting the interval between the second abutting portion 233 and the machining start position.
Further, in order to avoid that the rotation restriction action of the first turntable 221 is restored by the stopper 231 after the first abutting portion 232 abuts against the second abutting portion 233, when the second abutting portion 233 and the third abutting portion 234 are provided, the second abutting portion 233 and the third abutting portion 234 are continuously provided, and the abutting height of the portion between the second abutting portion 233 and the third abutting portion 234 is not lower than the abutting height of the second abutting portion 233.
It should be further noted that, in the bending process of the efficient bending machine 200, the rotation of the second rotary table 222 includes a bending process of a to-be-bent piece, a process of driving the limiting table 231 to move and a process of driving the first rotary table 221 to move, and when the first rotary table 221 is driven to move, the bending process of the to-be-bent piece is already performed in the process, and a to-be-bent piece is conveniently taken, so that in the process of driving the second rotary table 222 to rotate, the second rotation can be a one-way continuous rotation, thereby simplifying the structure, reducing the control cost, and facilitating the improvement of the bending efficiency.
The working principle of the efficient bending machine 200 is as follows:
after the piece to be bent extends into the bending area 201 and abuts against the abutting post 226, the second turntable 222 is driven by the rotating motor to rotate relative to the main frame body 210, so that the piece to be bent can be bent, and along with the continuous rotation of the second turntable 222, when the second turntable 222 rotates to the position where the first abutting portion 232 abuts against the second abutting portion 233, along with the continuous rotation of the second turntable 222, the limiting table 231 can be driven to move towards the direction close to the main frame body 210 along the central axis direction of the first turntable 221, so that the limiting table 231 is disengaged from the first turntable 221, that is, the rotation limiting effect of the first turntable 221 disappears, at this time, the rotation of the second turntable 222 can drive the first turntable 221 to synchronously rotate, and the bending effect of the piece to be bent of the second turntable 222 disappears, so that the bending angle can be ensured through the abutting effect of the first abutting portion 232 and the second abutting portion 233, avoiding the occurrence of bending errors. Moreover, after bending, in order to avoid the to-be-bent piece from being tightly clamped in the bending area 201, the second turntable 222 continuously rotates, so that the first abutting portion 232 and the third abutting portion 234 abut against each other, the first turntable 221 can be driven to move in the direction close to the main frame body 210 along the axis direction thereof through the abutting of the first abutting portion 232 and the third abutting portion 234, the to-be-bent pieces in the bending area 201 can be separated from the plurality of bending columns 225 on the first turntable 221, and material taking is facilitated.
Through the structural arrangement, the bending angle can be ensured in the bending process, and the second abutting part 233 is detachably connected with the limiting table 231, so that the bending angle can be adjusted through adjusting the position of the second abutting part 233, and the bending processing range can be expanded; moreover, after the bending process is completed, the bending column 225 on the first rotary table 221 can be separated from the piece to be bent through the movement of the first rotary table 221, so that the material can be conveniently taken, the labor intensity of workers can be reduced, and the bending cost of the piece to be bent can be reduced.
Further, in the embodiment, when the first turntable 221 and the second turntable 222 are disposed, in order to facilitate the second turntable 222 to be sleeved outside the first turntable 221 and enable the first turntable 221 to be matched with the limit table 231, the first turntable 221 includes a first cylinder and a second cylinder which are stacked; the first cylinder and the second cylinder are coaxial, and the second cylinder and the first cylinder are fixedly connected towards the end face of the main frame body 210; the second rotary table 222 and the limiting table 231 are both annular bodies, the inner circumferential surface of the second rotary table 222 is adapted to the outer circumferential surface of the first cylinder, and the inner circumferential surface of the limiting table 231 is adapted to the outer circumferential surface of the second cylinder; the end surfaces of the first cylinder and the second turntable 222 away from the main frame 210 are parallel.
Further, in the present embodiment, in order to facilitate adjustment of the bending region 201 to increase the processing range of bending, a positioning column and a plurality of screw holes are disposed on a surface of the first turntable 221, which is in contact with the bending table 223; the positioning column is positioned in the center of the bending table 223 and extends along the central axis of the first rotating table 221; the screw holes are arranged around the positioning column around the central axis direction of the first rotating table 221; the bending table 223 is provided with a positioning hole and a plurality of connecting holes, and the positioning hole is located at the center of the bending table 223 and is used for being matched with the positioning column; the plurality of connecting holes are positioned on the periphery of the positioning hole and correspond to the plurality of screw holes one to one; bending assembly 220 also includes a plurality of connecting posts that mate with a plurality of connecting holes and a plurality of screw holes to secure bending station 223 to first turntable 221.
In order to facilitate the adjustment of the position of the bending columns 225 on the bending table 223, a plurality of mounting portions are provided on the bending table 223, and each bending column 225 is detachably connected with one.
In this embodiment, the high-efficiency bending machine 200 includes four bending columns 225, and the four bending columns 225 are arranged in parallel with each other.
Further, in the present embodiment, in order to enable the limiting table 231 to limit the rotation of the first turntable 221, the outer circumferential surface of the first turntable 221 is provided with external teeth and a limiting portion 235, and the inner circumferential surface of the limiting table 231 is provided with internal teeth; the limiting part 235 is positioned on one side of the outer peripheral surface of the first rotating platform 221, which is far away from the main frame body 210, along the central axis direction of the first rotating platform 221; the outer teeth are for meshing with the inner teeth to restrict rotation of the first turntable 221; the stopper 235 abuts against the stopper 231 to restrict the movement of the first turntable 221 relative to the first turntable 221.
Further, in the present embodiment, the second abutting portion 233 and the third abutting portion 234 are both detachably connected to the position limiting table 231; the second abutting portion 233 and the third abutting portion 234 are both arc-shaped protrusions; and the maximum projection height of the second abutment 233 is smaller than the maximum projection height of the third abutment 234.
In order to allow the first rotary table 221 to return to the position for bending the to-be-bent member, that is, the third abutting portion 234 abuts against the first abutting portion 232, so that the first rotary table 221 can return to the position where the first cylinder and the second rotary table 222 are parallel to the end surface away from the main frame 210 after moving in the direction close to the main frame 210, the efficient bending machine 200 further includes a first elastic member and a first elastic member, and the first elastic member is used for allowing the first rotary table 221 to have a tendency to move in the direction close to the main frame 210.

It should be noted that, firstly, in order to avoid the displacement of the first rotating table 221 that affects the processing, when the first elastic member is disposed, and when the to-be-bent member is placed on the first rotating table 221, the pressure applied to the first rotating table 221 by the to-be-bent member does not drive the first rotating table 221 to displace.
