DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1 and Figure 4 As shown, the utility model provides a bending machine for processing refrigerator condenser tubes, comprising a fixed seat 1, a mounting seat 2 sliding on one side of the fixed seat 1 and a bending assembly, a linear guide rail is arranged on one side of the fixed seat 1 for driving the mounting seat 2 to adjust the position, the bending assembly comprises a bending wheel 3, a first arc groove plate 4 and a second arc groove plate 5, the diameter of the bending wheel 3 determines the bending diameter, so the bending diameter can be adjusted by replacing the bending wheels 3 with different diameters, a rotating disk 6 is arranged on the top of the fixed seat 1, the bottom of the rotating disk 6 passes through the fixed seat 1 and extends to the inside of the fixed seat 1, and the top of the rotating disk 6 is fixedly connected to a limiting column 7, and the limiting column 7 is connected to the bending wheel 3 through a mounting mechanism 8;

[0027] The mounting mechanism 8 includes a bidirectional threaded rod 81, a through slot 82 is provided inside the limiting column 7, and a vertical rod 83 is rotatably connected to the bottom of the inner wall of the through slot 82, a worm wheel 84 is fixedly connected to the surface of the vertical rod 83, a worm 85 adapted to the worm wheel 84 is fixedly connected to the middle of the bidirectional threaded rod 81, sleeves 86 are threadedly connected to both sides of the surface of the bidirectional threaded rod 81, and vertical plates 87 are fixedly connected to the tops of the two sleeves 86, and blocks 88 are fixedly connected to the opposite sides of the two vertical plates 87;

[0028] The two ends of the bidirectional threaded rod 81 are rotatably connected to the two sides of the inner wall of the through slot 82 respectively. The bottom of the bending wheel 3 is provided with a cavity 9 adapted to the limit column 7, and both sides of the inner wall of the cavity 9 are provided with a clamping groove 10 adapted to the clamping block 88. The top of the vertical plate 87 is slidably connected to the top of the inner wall of the through slot 82.

[0029] The top of the vertical rod 83 passes through the limiting column 7 and extends to the outside of the bending wheel 3. The top of the first arc-shaped groove plate 4 is fixedly connected with a mounting block 11, and the surface thread of the mounting block 11 passes through a screw 12. The threaded end of the screw 12 passes through the vertical rod 83 and extends to the inside of the vertical rod 83. The arrangement of the mounting block 11 and the screw 12 facilitates the fixing of the angle of the vertical rod 83 to prevent the vertical rod 83 from rotating without the action of external force, resulting in an unstable connection between the clamping block 88 and the clamping groove 10.

[0030] Both sides of the top of the rotating disk 6 are fixedly connected with mounting rods 13, and both sides of the bottom of the bending wheel 3 are provided with grooves 14 adapted to the mounting rods 13. The arrangement of the mounting rods 13 and the grooves 14 facilitates the installation of the bending wheel 3 to limit the position, thereby improving the installation accuracy and work efficiency;

[0031] A first motor 15 is fixedly connected to the bottom of the inner wall of the fixed base 1, and one end of the output shaft of the first motor 15 is fixedly connected to the bottom of the rotating disk 6 through a coupling. The first arc groove plate 4 is fixed to one side of the bending wheel 3, and the second arc groove plate 5 is fixed to the back of the first arc groove plate 4. A hole for the condenser to pass through is provided between the opposite sides of the first arc groove plate 4 and the second arc groove plate 5. By replacing the bending component, the size of the hole between the first arc groove plate 4 and the second arc groove plate 5 is different, so as to adapt to the limiting of condenser tubes of different diameters.

[0032] Through the arrangement of the above structure, the first motor 15 is started to drive the rotating disk 6 to rotate. The rotating disk 6 drives the bending assembly to rotate with the bending wheel 3 as the center to bend the condenser. The vertical rod 83 can be rotated by unscrewing the screw 12 out of the vertical rod 83. The vertical rod 83 drives the worm 85 to rotate through the worm gear 84, so that the bidirectional threaded rod 81 is rotated, thereby driving the two sleeves 86 to move in relative directions. Under the sliding action of the vertical plate 87, the sleeve 86 drives the block 88 to move out of the slot 10, so that the bending assembly can be disassembled from the limit column 7, so that different sizes of bending assemblies can be replaced according to the diameter of the condenser and the diameter required to be bent. After the size of the bending assembly is changed, the position of the mounting seat 2 is adjusted by the linear guide rail, and the clamping position of the limit assembly on the condenser is aligned with the perforation of the bending assembly, so as to facilitate subsequent bending processing.

[0033] Embodiment 2

[0034] Based on Example 1, please refer to Figure 1 , Figure 5 and Figure 6 As shown, a second motor 16 is fixedly connected to one side of the mounting base 2, and one end of the output shaft of the second motor 16 is fixedly connected to a screw rod 17 through a coupling, and one end of the screw rod 17 away from the second motor 16 is rotatably connected to one side of the inner wall of the mounting base 2, and the front and back sides of the bottom of the inner wall of the mounting base 2 are slidably connected with vertical plates 18, and the top of the vertical plates 18 penetrates the mounting base 2 and extends to the top of the mounting base 2, and a horizontal plate 19 is fixedly connected between the opposite sides of the two vertical plates 18, and the surface of the screw rod 17 is connected to the internal thread of the horizontal plate 19, and a limiting assembly is arranged on the top between the opposite sides of the two vertical plates 18, and the limiting assembly is located at the top of the mounting base 2, and the limiting assembly includes two cylinders 20, and the two cylinders 20 are respectively fixed on the opposite sides of the two vertical plates 18, and one end of the output shaft of the cylinder 20 is fixedly connected to a clamping plate 21, and the clamping position of the clamping plate 21 is arranged as a triangular groove, which can clamp condenser tubes of different sizes.

[0035] Through the arrangement of the above structure, when in use, the cylinder 20 drives the clamping plate 21 to fix and clamp the condenser, and then the second motor 16 is started to drive the screw rod 17 to rotate, and the limit assembly is driven by the cross plate 19 to move on the screw rod 17, so as to transport the clamped condenser to the bending assembly. After the condenser passes through a section of the bending assembly, the clamping of the condenser is released, and the two clamping plates 21 only play a limiting role on the condenser. At this time, the condenser can be bent through the bending assembly.
