[0033] In summary: the utility model discloses a CNC pipe bending machine with continuous automatic unloading. The operator stacks the rectangular pipes to be bent in the storage cavity 32. At this time, the bottom group of rectangular pipes is just opposite to the through-port 33. The pusher block 34, the through-port 33 and the pipes match each other. When the device needs to feed, the user turns on the first motor 37. The first motor 37 rotates to drive the first reciprocating screw 38 to rotate. The first reciprocating screw 38 will drive the moving block 392 to move horizontally to the left or right along the first reciprocating screw 38. The moving plate 391 moves along the limit rod The push block 34 moves horizontally to the left or right until it enters the inner cavity of the through port 33. The push block 34 pushes the pipe fittings at the bottom of the storage cavity 32 out of the through port 33 and pushes this group of pipe fittings onto the top surface of the conveyor belt 21. The first reciprocating screw rod 38 then drives the move block 392, the L-shaped connection block 35 and the push block 34 to move horizontally to the right until the push block 34 completely leaves the through port 33. At this time, the next pipe fitting to be processed in the storage cavity 32 falls into the storage cavity 33. 2 is the lowest layer, waiting for subsequent feeding and processing work; when a group of pipe fittings is pushed on the top surface of the conveyor belt 21, the user turns on the driving component that controls the conveyor belt 21, and the pipe fittings are conveyed to the inner cavity of the bending chamber assembly 1 through the conveyor belt 21. When the objects are conveyed to the top surface of the workbench 11, the pipe fittings are positioned and fixed on the side by the clamping driving component 14. The two groups of clamping plates position one end of the pipe fitting, and the end position of the pipe fitting to be bent is in front of the push block 13 at this time. The two groups of hydraulic cylinders 12 are started and pushed out, and the hydraulic cylinders 12 drive the push block 13 to approach the bent end of the pipe fitting until the push block 13 After giving thrust to the end of the pipe fitting and completing the bending work, the two groups of hydraulic cylinders 12 are retracted; subsequently, the user turns on the working mode of the first motor 37 to make the push block 34 move horizontally back and forth, and the push block 34 continues to push the bottom layer of the workpiece in the storage cavity 32 for loading, and the above working steps are repeated until the workpiece in the storage cavity 32 is processed. This can automatically and continuously convey the pipe fittings for feeding through the feeding component 3 and the transmission chamber component 2. The whole operation is simple, and the automated operation improves the feeding efficiency, avoids the time-consuming and labor-intensive manual loading, and improves the practicality of the equipment;

[0034] In order to prevent the pipe from deviating when being transported on the conveyor belt 21, two sets of limit blocks 292 can be used for deviation correction. The user turns on the second motor drive on one side of the active roller 22 to rotate the active roller 22, and the conveyor belt 21 drives the conveyor belt 21 to transmit and the passive roller 23 also rotates at the same time. The rotation of the passive roller 23 drives the two sets of connecting rods 24 to rotate, and the connecting rods 24 drive the two sets of first rollers 25 to rotate. The first rollers 25 drive the two sets of second rollers 28 to rotate through the transmission effect of the belts 26. The two sets of second rollers 28 drive the two sets of second reciprocating screws 27 to rotate. The driving of the multi-thread rod 27 will cause the two groups of reciprocating blocks 291 to make horizontal reciprocating movements along the fixed rod 29, and then the two groups of limit blocks 292 will make alternating reciprocating movements approaching and moving away from each other. The two groups of limit blocks 292 are located on both sides of the pipes conveyed on the conveyor belt 21. Once the pipes conveyed on the conveyor belt 21 are offset, the two groups of limit blocks 292 will touch and limit the pipes, and correct them back to their original correct tracks. This arrangement, through the cooperation of the conveyor belt 21 and the two groups of limit blocks 292, is conducive to correcting the deviation of the conveyed pipes, and prevents the deviation of the pipes from affecting the quality of subsequent bending of the equipment and reducing the practicality of the equipment.
