Description

Technical Field

[0001] The present application relates to the technical field of pipe processing, and in particular to a fully automatic expanding and bending machine. Background Art

[0002] Pipe bending machines are used to bend metal pipes and are widely used in industrial fields such as air conditioning, automobiles, and ships.

[0003] The pipe bending machine includes a frame, on which a circular die and a clamping die for controlling the bending radius are installed. Before bending the metal pipe, both ends of the metal pipe need to be expanded and the surrounding wall of the metal pipe needs to be pierced. In the related art, expanding equipment and piercing equipment are often used to expand and pierce the metal pipe. When bending the pipe fitting, the staff needs to place the metal pipe to be bent between the circular die and the clamping die. The circular die and the clamping die clamp the pipe fitting together, and the circular die rotates to drive the pipe fitting to bend. The pipe bending machine includes a left-bending type pipe bending machine and a right-bending type pipe bending machine. When the structure of the metal pipe is more complicated and it needs to be bent in multiple directions at the same time, it is necessary to use a left-bending type pipe bending machine and a right-bending type pipe bending machine to bend the metal pipe.

[0004] Regarding the related technology, the inventor also believes that when the bending structure of the metal pipe is more complicated, in the process of bending the metal pipe, it is necessary to use a left-type pipe bender and a right-type pipe bender to bend the metal pipe. The staff needs to move the metal pipe from the left-type pipe bender to the right-type pipe bender or from the right-type pipe bender to the left-type pipe bender, and the processing efficiency of the metal pipe is low. Summary of the invention

[0008] By adopting the above technical solution, when bending the metal tube, the first clamping assembly clamps the metal tube. When the metal tube needs to be bent to the left, the first driving member drives the die changing disk to rotate and moves the left bending assembly to the working area. The sliding assembly drives the clamping die to move close to the metal tube. The clamping die cooperates with the left bending assembly to achieve the left bending of the metal tube. When the metal tube needs to be bent to the right, the first driving member drives the die changing disk to rotate and moves the right bending assembly to the working area. The right bending assembly cooperates with the clamping die to achieve the right bending of the metal tube. During the processing of the metal tube, the staff does not need to switch the metal tube between the left bending type tube bending machine and the right bending type tube bending machine, thereby improving the processing efficiency of the metal tube.

[0039] The embodiment of the present application discloses a fully automatic expanding and bending machine.

[0040] Reference Figure 1 A fully automatic expanding and bending machine comprises a frame 1, on which a feeding area for conveying metal pipes, an expanding area for expanding the metal pipes, and a bending area for bending the metal pipes are formed.

[0041] The frame 1 is located in the feeding area and is slidably installed with a feeding component 2 for moving the metal pipe to the flaring area. The frame 1 is located in the flaring area and is provided with a first flaring table 3 and a second flaring table 4 for flaring the metal; the frame 1 is located between the flaring area and the bending area to form a moving component 5 for moving the flared metal pipe to the bending area. The frame 1 is located in the bending area and is rotatably installed with a die changing plate 6 and a first driving member 7 for driving the die changing plate 6 to rotate. The peripheral wall of the die changing plate 6 is installed with a left bending component 8 for driving the metal pipe to bend left and a right bending component 9 for driving the metal pipe to bend right. The frame 1 is slidably installed with a clamping die 10 that matches the left bending component 8 or the right bending component 9. The frame 1 is located in the bending area and is slidably installed with a first clamping component 11 for clamping the metal pipe.

[0042] Reference Figure 1 and 2 , the first driving member 7 is a servo motor, and the output shaft of the first driving member 7 is in the horizontal direction, and the servo motor is convenient for controlling the rotation angle of the mold changing disk 6. The left bending component 8 and the right bending component 9 have the same structure, and both are located on the peripheral wall of the mold changing disk 6. In the present embodiment, the angle between the left bending component 8 and the right bending component 9 is 90°. Both the left bending component 8 and the right bending component 9 can independently bend the bent pipe. When the metal pipe needs to be bent to the left, the mold changing disk 6 drives the left bending component 8 to rotate to the working area. When the metal pipe needs to be bent to the right, the mold changing disk 6 drives the right bending component 9 to rotate to the working area. During the processing of the metal pipe, the staff does not need to switch the metal pipe between the left bending type pipe bending machine and the right bending type pipe bending machine, thereby improving the processing efficiency of the metal pipe.

[0043] Reference Figure 2The left-bending assembly 8 includes an upper circular mold 81, a lower circular mold 82 and a second driving member 83 driven by air pressure. The second driving member 83 includes a power unit 831, a rotating shaft 832 and a telescopic shaft 833. The power unit 831 is connected to the air source to provide power. The power unit 831 is fixed to the peripheral wall of the mold changing plate 6 by bolt connection, the rotating shaft 832 is rotatably mounted on the end of the power unit 831 away from the mold changing plate 6, and the telescopic shaft 833 is slidably mounted on the rotating shaft 832. The upper circular mold 81 is fixed to the telescopic shaft 833, and the lower circular mold 82 is fixed to the rotating shaft 832. The power unit 831 can drive the rotating shaft 832 and the telescopic shaft 833 to rotate coaxially, and the power unit 831 can also drive the telescopic shaft 833 to telescopically move.

[0044] Reference Figure 2 and Figure 3 An annular groove 12 that fits the tube wall of the metal tube is formed between the upper circular die 81 and the lower circular die 82. An upper baffle 13 is integrally connected to the side wall of the upper circular die 81 close to the lower circular die 82, and a lower baffle 14 is integrally connected to the side wall of the lower circular die 82 close to the upper circular die 81. When the metal tube is bent, the first clamping assembly 11 clamps the metal tube, and the first clamping assembly 11 moves the metal tube between the upper circular die 81 and the lower circular die 82.

At the same time, the groove wall of the annular groove 12 is pressed against the tube wall of the metal tube, and the upper baffle 13 and the lower baffle 14 both abut against the groove wall of the metal tube away from the annular groove 12. The second driving member 83 drives the upper circular die 81 and the lower circular die 82 to rotate coaxially, so that the metal tube is bent along the trajectory of the annular groove 12.

[0045] In order to improve the bending stability of the metal tube, when the metal tube is bent, the clamping die 10 abuts against the peripheral wall of the metal tube, and the two side walls of the clamping die 10 that are far away from each other respectively form a first clamping groove 15 and a second clamping groove 16 that fit the metal tube wall, and the first clamping groove 15 and the second clamping groove 16 are both semicircular grooves. When the metal tube is bent to the left, the groove wall of the first clamping groove 15 abuts against the side wall of the metal tube away from the left bending component 8, and when the metal tube is bent to the right, the groove wall of the second clamping groove 16 abuts against the groove wall of the metal tube away from the right bending component 9. When the metal tube is bent, the clamping die 10 can apply a force opposite to the bending direction of the metal tube to the metal tube through the first clamping groove 15 and the second clamping groove 16, so that the metal tube is not easy to shake during the bending process, and the bending accuracy of the metal tube can be improved.

When it is necessary to pull a hole in the metal tube, the fifth driving member 28 drives the pulling hole core rod 25 to move. When the pulling hole core rod 25 moves, the contact position between the first inclined surface 26 and the second inclined surface 27 changes, and the pulling hole punch 24 slides outward along the sliding hole 221. The pulling hole punch 24 acts on the inner circumferential wall of the metal tube, and the pulling hole punch 24 penetrates the metal tube wall to complete the pulling hole of the metal tube.

[0060] Reference Figure 1 and Figure 8 , the moving assembly 5 includes a fourth screw rod 51, a fourth sliding block 52, a translation cylinder 53 and an electric clamp 54. The fourth screw rod 51 is rotatably installed at a high position of the frame 1, that is, the height of the fourth screw rod 51 is higher than the flaring area and the bending area. The axis of the fourth screw rod 51 is parallel to the axis of the first screw rod 172, and a servo motor for driving the fourth screw rod 51 to rotate is installed on the frame 1. The fourth screw rod 51 is penetrated by the fourth sliding block 52, and the fourth screw rod 51 is threadedly matched with the fourth sliding block 52.

[0062] The implementation principle of the fully automatic flaring and bending integrated machine in the embodiment of the present application is as follows: when processing a metal tube, the feeding assembly 2 works, the first clamping cylinder 205 and the second clamping cylinder 206 drive the left clamping plate 207 and the right clamping plate 208 to clamp the metal rod, and the second movable slide 203 drives the metal tube to move toward the flaring area. When flaring, the feeding assembly 2 delivers the metal tube to the positioning hole 30, and the transmission assembly 29 drives the second flaring column 32 to move toward the metal tube to complete the flaring of one end of the metal tube. Afterwards, the transmission assembly 29 drives the second clamping assembly 33 to move close to the metal tube, the feeding assembly 2 releases the clamping of the metal tube, the second clamping assembly 33 clamps the metal tube, and the transmission assembly 29 drives the metal tube to move toward the first flaring column 31 to flare the other end of the metal tube.

[0063] After the metal tube is expanded, the electric clamp 54 clamps the expanded metal tube, and the fourth screw 51 rotates to drive the electric clamp 54 clamping the metal tube to translate to the bending area. The translation cylinder 53 can drive the electric clamp 54 to move close to the first clamping assembly 11, and the pneumatic clamp 116 clamps the metal tube. The support tube 22 supports the metal rod. When it is necessary to pull a hole in the metal tube, the fifth driving member 28 drives the pulling core rod 25 to move, and the pulling core rod 25 pushes the pulling punch 24 to pull a hole in the metal tube. At the same time, according to the requirements of the bending direction of the metal tube, the die changing plate 6 can switch the left bending component 8 or the right bending component 9 to the working area. When the metal tube is bent, the upper circular die 82 and the lower circular die 82 clamp the metal tube, and the clamping die 10 abuts against the side wall opposite to the bending direction of the metal tube. The second driving member 83 drives the upper circular die 81 and the lower circular die 82 to rotate, and the metal tube rotates along the annular groove 12 to form a bend.

[0064] The driving motor 1131 can drive the metal tube to move, and the rotating motor 19 drives the metal tube to rotate, so as to control the bending position and the bending angle of the metal tube, thereby achieving high processing efficiency for the metal tube.
