DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A device for bending and forming a copper tube of an air conditioner comprises a bottom plate 100, a metal center 101 is fixedly mounted on the bottom plate 100, a rubber bending block 102 is fixedly sleeved on the metal center 101, a sliding block 200 is slidably mounted on the top side of the bottom plate 100, two driving rods 201 are rotatably mounted on the sliding block 200, and a rotating bending block 103 is rotatably mounted on the other end of the two driving rods 201, and the two rotating bending blocks 103 are both slidably mounted on the top side of the bottom plate 100. On the side, the rubber bending block 102 and the rotating bending block 103 are both provided with arc grooves 104, and the arc grooves 104 on both sides are adapted to each other, and the two rotating bending blocks are used to push the copper tube to bend and deform on the metal center and the rubber bending block. Compared with the manual bending of the copper tube, the metal center, the rubber bending block and the rotating bending block have a larger force-bearing area and a more uniform force, making the bending part more lubricated and natural, and not prone to flattening or breakage. U-shaped and L-shaped copper tubes can also be processed according to needs.

[0023] In an optional embodiment: a U-shaped rack 300 is fixedly installed on the top side of the base plate 100, two mounting blocks 202 are fixedly installed on the top side of the sliding block 200, and the same power gear 203 is rotatably installed between the two mounting blocks 202, the power gear 203 is meshed with the U-shaped rack 300, and an operating rod 204 is movably installed on the side of the power gear 203, and the operating rod 204 is provided with anti-slip grooves 205. A connecting slot 207 is provided at one end of the operating rod 204 close to the power gear 203, and a connecting block 208 is movably installed in the connecting slot 207. The connecting block 208 is fixedly installed on the side of the power gear 203, and a reset knob 209 is fixedly installed on the other side of the power gear 203.

[0024] It should be noted that the operating rod 204 is clamped on the connecting block 208 through the connecting slot 207 to drive the power gear 203 to rotate. The anti-slip pattern 205 on the operating rod 204 can fit the user's hand to avoid slipping. Since the rotation angle of the operating rod 204 is limited, the operating rod 204 needs to be constantly removed and reinstalled to ensure the continuous rotation of the power gear 203, thereby achieving continuous and uniform control of the copper tube for bending, avoiding flattening and breakage caused by bending too quickly.

[0025] In an optional embodiment: a positioning groove 301 is opened on the top side of the bottom plate 100 , and a positioning pin 302 is inserted into the positioning groove 301 .

[0026] It should be noted that one end of the driving rod 201 is fixed at the position of the positioning slot 301 by the positioning pin 302, so that only one end of the copper tube is bent.

[0027] In an optional embodiment: a sliding T-slot 210 is opened on the bottom side of the sliding block 200, a sliding track 206 is slidably installed in the sliding T-slot 210, and the sliding track 206 is fixedly installed on the top side of the base plate 100. When the sliding block 200 moves, the sliding T-slot 210 and the sliding track 206 are first restricted to move only on the fixed track.

[0028] In an optional embodiment: driving holes 2011 are provided at both ends of the driving rod 201, and driving shafts 2012 are rotatably installed in the two driving holes 2011. The two driving shafts 2012 are respectively fixedly installed on the top sides of the sliding block 200 and the rotating bending block 103. The movable sliding block 200 drives the driving rod 201 to move its position through the driving hole 2011 and the driving shaft 2012, and the driving rod 201 drives the rotating bending block 103 to move on the base plate 100 through the driving hole 2011 and the driving shaft 2012 at the other end.

[0029] In an optional embodiment: two movable grooves 1033 are opened on the top side of the bottom plate 100 , and movable blocks 1034 are slidably installed in the two movable grooves 1033 . The two movable blocks 1034 are movably installed on the bottom sides of the two rotating bending blocks 103 .

[0030] It should be noted that the movable groove 1033 and the movable block 1034 at the bottom side of the rotating bending block 103 ensure that it can slide a certain distance after rotation.

[0031] In an optional embodiment: the rotating bending block 103 has a rotating hole 1031 on it, a rotating shaft 1032 is rotatably installed in the rotating hole 1031, and the rotating shaft 1032 is fixedly installed on the top side of the movable block 1034. It should be noted that the rotating bending block 103 can be rotated while moving through the rotating hole 1031 and the rotating shaft 1032, thereby achieving the effect of bending the two ends of the copper tube.

[0032] Working principle of this utility model:

[0033] When using the device, first, the copper tube needs to be placed between the two rotating bending blocks 103 and the rubber bending block 102. After the rotating bending block 103 moves, the arc grooves 104 on both sides can ensure that the position of the copper tube is fixed. At this time, the user can rotate the operating rod 204, and the operating rod 204 is stuck on the connecting block 208 through the connecting slot 207, thereby driving the power gear 203 to rotate. The anti-slip pattern 205 on the operating rod 204 can fit the user's hand to avoid slipping. Since the rotation angle of the operating rod 204 is limited, the operating rod 204 needs to be constantly removed and reinstalled to ensure the continuous rotation of the power gear 203, so as to achieve continuous and uniform control of the copper tube to bend, avoiding the flattening and breakage problems caused by too fast bending. The rotating power gear 203 walks on the U-shaped rack 300, thereby driving itself and the sliding block 200 and the driving rod 201 to move. When the sliding block 200 moves, it first slides the T-slot 210 and the sliding track 206 to the fixed track. The movable sliding block 200 drives the driving rod 201 to move through the driving hole 2011 and the driving shaft 2012, and the driving rod 201 drives the rotating bending block 103 to move on the bottom plate 100 through the driving hole 2011 and the driving shaft 2012 at the other end. At the same time, the rotating bending block 103 can be rotated while moving through the rotating hole 1031 and the rotating shaft 1032, thereby achieving the effect of bending both ends of the copper tube. The movable groove 1033 and the movable block 1034 on the bottom side of the rotating bending block 103 ensure that it can slide one end distance after rotation. If an L-shaped copper tube needs to be processed, one end of the driving rod 201 can be fixed to the position of the positioning groove 301 through the positioning pin 302, thereby achieving that only one end of the copper tube will be bent.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
