[0030] The embodiment of the present invention provides a pipe bending device for producing air-conditioning condensers. Figures 1 to 4 As shown, a pipe bending device for producing air conditioner condensers includes: a base frame 1, a first bracket 11, a first driving part, a first motor 12, a first gear 13, two chucks 14, a second bracket 15, two sets of bending parts and a second driving part, wherein:

[0031] The first bracket 11 is arranged on the top of the base frame 1;

[0032] The first driving part is in transmission connection with the first bracket 11, and is used for driving the first bracket 11 to move on the base frame 1;

[0033] The first motor 12 is disposed on the first bracket 11;

[0034] The first gear 13 is disposed on the rotating shaft of the first motor 12;

[0035] The two chucks 14 are rotatably connected to the first bracket 11, and the two chucks 14 are respectively meshed with the upper and lower ends of the first gear 13;

[0036] The second bracket 15 is arranged on the top of the base frame 1;

[0037] The two groups of bending parts are arranged on the second bracket 15;

[0038] The second driving part is in driving connection with the bending part, and is used for driving the bending part to perform a bending operation.

[0039] When the device is used to bend the condenser pipe, the two pipes are respectively installed on the two chucks 14, and the two pipes pass through the two bending parts respectively, and then the second driving part drives the bending part to perform the bending operation. After completing one bending operation, the first driving part drives the first bracket 11 to move to the right to realize the feeding of the pipe, and then the first motor 12 drives the first gear 13 to rotate, and the first gear 13 drives the two chucks 14 to rotate, and then the pipe is rotated to 180 degrees. At this time, the second bending operation can be performed, and this is repeated.

[0040] From the above, it can be seen that the device can bend two pipes at one time through the design of two sets of bending parts, thereby improving the efficiency of the pipe bending operation.

[0041] In some embodiments, the first driving unit includes a second motor 2 , a screw is disposed on a rotating shaft of the second motor 2 , the screw is threadedly connected to the first bracket 11 , and the first bracket 11 is slidably connected to the base frame 1 .

[0042] During operation, the second motor 2 drives the screw to rotate, and the screw drives the first bracket 11 to move on the base frame 1, thereby driving the pipe on the chuck 14 to move, thereby realizing the feeding operation.

[0043] In some embodiments, the bending portion includes a platform 31, a bending wheel 32 and a clamping portion, the platform 31 is arranged on the second bracket 15, a first cylinder 33 is provided on the platform 31, a sliding member 34 is provided at one end of the first cylinder 33, the sliding member 34 has a first groove, the bending wheel 32 has a second groove, and the clamping portion is used to fix one end of the pipe during bending.

[0044] Optionally, the second driving unit includes a third motor 41 , a second gear 42 is provided on the rotating shaft of the third motor 41 , the second gear 42 is meshed with a third gear 43 , the third gear 43 is sleeved with a rotating shaft 44 , and the two bending wheels 32 are arranged on the rotating shaft 44 .

[0045] Optionally, the pressing portion includes a support plate 51 disposed on the rotating shaft 44 , a second cylinder 52 is disposed on the support plate 51 , a pressing block 53 is disposed on the telescopic shaft of the second cylinder 52 , and a third groove is formed on the pressing block 53 .

[0046] When bending, the pipe passes through the first groove and the second groove, and then the second cylinder 52 drives the third groove on the clamping block 53 to clamp the pipe in the second groove, and then the third motor 41 drives the second gear 42 to rotate, the second gear 42 drives the third gear 43 to rotate, and the third gear 43 drives the rotating shaft 44 to rotate, thereby driving the bending wheel 32 and the clamping block 53 to rotate at the same time, and at the same time the first cylinder 33 drives the sliding member 34 to move to the right, thus completing the bending operation. When it is necessary to rotate the pipe to 180 degrees, first make the clamping block 53 loosen the pipe.

[0047] In some embodiments, the rotating shaft 44 includes an upper section 61, a lower section 62 and a middle section 63. The middle section 63 is fixedly connected to the lower section 62 and is rotatably connected to the upper section 61. The upper section 61 and the lower section 62 are both provided with protrusions, and the protrusions are detachably connected to a connecting plate 64. When the connecting plate 64 cooperates with the protrusions, the lower section 62 can drive the upper section 61 to rotate. When the connecting plate 64 is separated from the protrusions, the upper section 61 does not rotate when the lower section 62 rotates.

[0048] When the quantity is not large, it may be necessary to bend only one pipe at a time. In order to allow the two bending parts to operate separately or simultaneously, the present invention designs a special rotating shaft 44. When the connecting plate 64 cooperates with the protrusion, the lower section 62 can drive the upper section 61 to rotate. At this time, the two bending parts can work simultaneously. When the connecting plate 64 is separated from the protrusion, when the lower section 62 rotates, it will only drive the middle section 63 to rotate. Since the middle section 63 is rotationally connected to the upper section 61, the upper section 61 does not rotate at this time, that is, the bending part of the upper section 61 does not work. In this way, the two bending parts can operate separately or simultaneously.

[0049] In some embodiments, the bending wheel 32 is detachably connected to the top of the rotating shaft 44. Specifically, the detachable connection can be performed by bolt connection, so that different types of bending wheels 32 can be easily replaced.

[0050] One or more embodiments of this specification are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification should be included in the scope of protection of this disclosure.
