The embodiment of the application relates to tubing bending equipment for heat exchanger production, which comprises the following implementation principles:
When a plurality of groups of pipes need to be synchronously bent, the rotating motor 21 is started, the driving gear 22 on the output shaft of the rotating motor 21 drives the driven gear 24 to synchronously rotate, so that the rotation of the rotating rod 23 is realized, and because the rotating rod 23 and the autorotation bending head 12 are coaxially arranged, the rotating rod 23 can drive the rotating arm 13 to revolve around the axis of the autorotation bending head 12 as the center when rotating, so that the revolution bending head 14 on the rotating arm 13 revolves around the axis of the autorotation bending head 12 as the center, and the plurality of groups of pipes can be synchronously bent at the same time.
When feeding of a plurality of groups of pipes is required, the feeding motor 31 is started, an output shaft of the feeding motor 31 drives the screw rod 32 to rotate, the sliding seat 33 is in threaded connection with the screw rod 32, and therefore the screw rod 32 rotates to drive the sliding seat 33 to move on the sliding rail 36, simultaneous movement of the plurality of groups of pipes is achieved, when feeding displacement of the plurality of groups of pipes is required to be respectively adjusted, the plurality of groups of feeding cylinders 34 are started, and the plurality of groups of feeding cylinders 34 perform different displacement compensation on the clamping die 35 through the pushing plate 37.
When the friction born by the pipe during bending needs to be reduced, the self-turning bending head 12 is vertically rotatably mounted on the mounting box 11, the revolution bending head 14 is vertically rotatably mounted on the rotating arm 13, and when the pipe is bent, the sliding friction born by the pipe can be converted into rolling friction, so that the friction born by the pipe is effectively reduced, and the abrasion to the outer surface of the pipe is reduced.
When the forming effect of the pipe needs to be detected, the laser emitter group 61 is started, if the bending section of the pipe is rebounded, the outer side edge of the pipe can block the light emitted by the laser emitter group 61, at the moment, the receiver group 62 can not receive illumination, signal output can be carried out, so that the bending effect of the pipe is detected, and the pipe which is unqualified in detection is repeatedly bent until the bending requirement is met.
