Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] The embodiment of the present application provides an intelligent mold for bending an air conditioner copper tube. The schematic diagram of the intelligent mold for bending an air conditioner copper tube is as follows: Figure 1-6 The intelligent mold for bending the air conditioner copper tube includes a bending table 10, one end of the top of the bending table 10 is connected to a clamping mechanism 20, and the other end of the top of the bending table 10 is connected to a bending mechanism 30;

[0033] The bending mechanism 30 includes a fixed wheel 31 connected to the upper surface of the bending table 10, a rotating rod 32 rotatably connected to the fixed wheel 31, and a movable wheel 33 rotatably connected to the rotating rod 32;

[0034] The inside of the wheel bodies of the fixed wheel 31 and the movable wheel 33 are both connected with magnetic suction components 34, and the magnetic suction components 34 are used to absorb the copper pipe of the air conditioner.

[0035] It should be noted that, in this embodiment, the air-conditioning copper tube is firmly clamped and bent. The adsorption effect of the magnetic component 34 effectively prevents the copper tube from sliding or deflecting during bending, thereby improving the bending accuracy and quality.

[0036] Optional, please refer to the attached Figure 1 There are multiple movable wheels 33, which are arranged at the bottom end of the rotating rod 32 along a linear array. A rotating shaft 331 is connected to the wheel body of the movable wheel 33, and the movable wheel 33 is rotatably connected to the rotating rod 32 through the rotating shaft 331.

[0037] In this embodiment, when the rotating rod 32 rotates, the multiple movable wheels 33 simultaneously exert force on the copper tube of the air conditioner to jointly complete the bending operation. The rotation of the movable wheels 33 can reduce the friction between the copper tube and make the bending process smoother.

[0038] Optional, please refer to the attached Figure 4 The magnetic attraction component 34 includes a first electromagnet ring 341 connected to the inside of the fixed wheel 31 and a second electromagnet ring 342 connected to the inside of the movable wheel 33. The second electromagnet ring 342 is connected to the outer surface of one end of the rotating shaft 331 extending to the inside of the movable wheel 33.

[0039] In this embodiment, the first electromagnet ring 341 in the magnetic attraction assembly 34 is installed inside the fixed wheel 31, and the second electromagnet ring 342 is installed on the outer surface of one end of the rotating shaft 331 extending to the inside of the movable wheel 33. When the first electromagnet ring 341 and the second electromagnet ring 342 are energized, they generate a magnetic field to attract the air conditioner copper pipe. By controlling the magnitude of the current, the strength of the magnetic field can be adjusted, thereby changing the magnitude of the adsorption force.

[0040] Optional, please refer to the attached Figure 1 and 6 A sliding rheostat 12 is connected to the upper surface of the bending table 10 , and the sliding rheostat 12 is electrically connected to the first electromagnet ring 341 and the second electromagnet ring 342 .

[0041] In this embodiment, the sliding rheostat 12 is connected to the upper surface of the bending table 10 and is electrically connected to the first electromagnet ring 341 and the second electromagnet ring 342. By changing the resistance of the sliding rheostat 12, the current in the first electromagnet ring 341 and the second electromagnet ring 342 can be adjusted, and then the adsorption force of the magnetic suction component 34 can be controlled, so that the stress distribution of the copper tube is different when bending at different angles. For example, when bending at a small angle, the deformation of the copper tube is relatively small, and the required adsorption force can be appropriately reduced; while when bending at a large angle, the external force on the copper tube is large, and a stronger adsorption force is required to maintain stability. The adsorption force of the magnetic suction component 34 is accurately controlled by the sliding rheostat 12, and can be adjusted in real time according to the specific bending angle requirements. When it is necessary to bend 30°, the adsorption force is reduced; when the bending angle increases to 90°, the adsorption force is increased in time to ensure that the copper tube will not slide due to insufficient adsorption force or be damaged due to excessive adsorption force during the bending process, thereby achieving high-precision processing of bending at different angles. The sliding rheostat 12 is used to detect the rotation angle so that the controller connected thereto can judge whether it is necessary to turn on and off the power of the electromagnet ring in time.

[0042] Optional, please refer to the attached Figure 6 The top of the rotating shaft 331 is connected to a gear plate 332 , one side of the gear plate 332 is meshedly connected to a rack 333 , one side surface of the rack 333 is connected to a sliding plate 334 , and the sliding plate 334 is slidably connected to one side of the sliding rheostat 12 .

[0043] In this embodiment, when the movable wheel 33 rotates, the rotating shaft 331 drives the gear plate 332 to rotate, and the meshing transmission between the gear plate 332 and the rack 333 causes the rack 333 to move, thereby driving the slide 334 to slide on the sliding rheostat 12, changing the resistance value of the sliding rheostat 12, and automatically adjusting the current of the first electromagnet ring 341 and the second electromagnet ring 342.

[0044] Optional, please refer to the attached Figure 1 An arc-shaped guide hole 13 is provided at the top of the bending platform 10 .

[0045] In this embodiment, the arc-shaped guide hole 13 at the top of the bending table 10 provides a motion track for the rotating shaft 331 at one end of the rotating rod 32 away from the fixed wheel 31. When the rotating rod 32 rotates around the fixed wheel 31, the rotating shaft 331 slides in the arc-shaped guide hole 13, limiting the rotation path of the rotating rod 32, so that the movable wheel 33 moves along a predetermined arc track.

[0046] Optional, please refer to the attached Figure 1 The cross section of the rotating rod 32 is L-shaped, and the rotating shaft 331 of the rotating rod 32 away from one end of the fixed wheel 31 extends into the hole body of the arc-shaped guide hole 13.

[0047] In this embodiment, when the motor 323 drives the rotating shaft 321 to rotate, the rotating rod 32 rotates around the fixed wheel 31, and the rotating shaft 331 moves along a predetermined arc trajectory under the constraint of the arc guide hole 13, driving the movable wheel 33 to bend the air conditioning copper tube.

[0048] Optional, please refer to the attached Figure 2 and 3 The clamping mechanism 20 includes a screw rod 21 rotatably connected to the top of the inner side of the bending platform 10, a first motor 22 connected to one end of the screw rod 21, and two sliders 23 connected to the outer surface of the screw rod 21, and a clamping wheel 24 is fixed to the top of the slider 23.

[0049] In this embodiment, in the clamping mechanism 20, the first motor 22 drives the screw rod 21 to rotate, and the rotation of the screw rod 21 drives the two sliders 23 to move relative to or away from each other on the screw rod 21. The clamping wheel 24 at the top of the slider 23 moves closer or farther away with the movement of the slider 23, thereby achieving the clamping and releasing operation of the air conditioner copper pipe.

[0050] Optional, please refer to the attached Figure 2 and 3 A guide hole 11 is provided at the top of the bending table 10. The guide holes 11 are symmetrically arranged and are used for the clamping wheel 24 to slide.

[0051] In this embodiment, the guide holes 11 at the top of the bending table 10 are symmetrically arranged, and the clamping wheels 24 slide in the guide holes 11 driven by the slider 23. The guide holes 11 provide a guide for the movement of the clamping wheels 24, ensuring that the moving direction of the clamping wheels 24 is accurate, so that the two clamping wheels 24 can accurately align and clamp the air conditioner copper pipe.

[0052] Optional, please refer to the attached Figure 4 The end of the rotating rod 32 close to the fixed wheel 31 is connected to a rotating shaft 321, and the rotating shaft 321 is rotatably connected to the fixed wheel 31. The bottom end of the rotating shaft 321 is connected to a reducer 322 through a coupling, and the input end of the reducer 322 is connected to a motor 323. The reducer 322 and the motor 323 are both connected to the inner top of the bending table 10.

[0053] In this embodiment, the power of the motor 323 is transmitted to the rotating shaft 321 through the reducer 322, and the reducer 322 reduces the speed of the motor 323 and increases the torque. The rotating shaft 321 drives the rotating rod 32 to rotate around the fixed wheel 31, so that the movable wheel 33 bends the air conditioner copper tube.

[0054] The specific operation mode of the present invention is as follows:

[0055] When using the air conditioning copper tube bending processing mold, start the first motor 22, the first motor 22 drives the screw rod 21 to rotate, and the screw rod 21 drives the two sliders 23 to move relative to each other, so that the clamping wheel 24 approaches and clamps the air conditioning copper tube under the guidance of the guide hole 11.

[0056] The first electromagnet ring 341 and the second electromagnet ring 342 are energized to generate magnetism, adsorb the copper tube of the air conditioner, and further stabilize the position of the copper tube. The motor 323 is started, and the motor 323 drives the rotating shaft 321 to rotate through the reducer 322, and the rotating shaft 321 drives the rotating rod 32 to rotate around the fixed wheel 31. The movable wheel 33 moves with the rotation of the rotating rod 32 to bend the copper tube of the air conditioner. During the rotation of the movable wheel 33, the rotating shaft 331 drives the gear plate 332 to rotate, and the meshing transmission between the gear plate 332 and the rack 333 moves the rack 333, thereby driving the sliding plate 334 to slide on the sliding rheostat 12, and automatically adjusting the current size of the first electromagnet ring 341 and the second electromagnet ring 342 to adapt to the different requirements for adsorption force during the bending process. At the same time, the rotating shaft 331 at one end of the rotating rod 32 away from the fixed wheel 31 moves under the guidance of the arc guide hole 13 to ensure the precise control of the bending angle.

[0057] After the bending is completed, the motor 323 is turned off, the power supply to the first electromagnet ring 341 and the second electromagnet ring 342 is stopped, the first motor 22 is started to make the screw rod 21 rotate in the opposite direction, the two sliders 23 move away from each other, the clamping wheel 24 releases the air-conditioning copper tube, and the bent copper tube is taken out.

[0058] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
