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 1-6 A current-assisted titanium bellows rolling forming device includes a frame 1, a working main machine 2 is arranged on one side of the frame 1, a servo motor 21 is movably arranged on the working main machine 2 through a mounting frame, a rotating shaft 3 is installed on the output end of the servo motor 21, and a plurality of mounting seats 5 are arranged on the rotating shaft 3. A driving wheel 4 is installed on each mounting seat 5, and the driving wheel 4 includes a first resistor block 41 and a second resistor block 42, and a first insulating block 411 and a second insulating block 421 are fixedly arranged on the parts where the first resistor block 41 and the second resistor block 42 contact each other.

[0023] The rotating shaft 3 can drive the driving wheel 4 to rotate, so that the bellows can be processed by the driving wheel 4. The driving wheel 4 is composed of a first resistor block 41 and a second resistor block 42, so that the driving wheel 4 can be easily replaced when it is worn.

[0024] Among them, a rotating connector 31 is provided at the end of the rotating shaft 3, a conductive slip ring 32 is sleeved on the other end of the rotating shaft 3, a wire 30 is provided through the middle of the inner cavity of the rotating shaft 3, and the two ends of the wire 30 are respectively connected to the rotating connector 31 and the conductive slip ring 32. The outside of the rotating connector 3 and the conductive slip ring 32 are both energized, through which the current can be conducted to the wire 30 in the rotating shaft 3, and the current conduction in the wire 30 will not be affected when the rotating shaft 3 rotates. It is also worth noting that the specific structure and working method of the rotating connector 3 and the conductive slip ring 32 are the prior art disclosed in the comparative documents in the background technology and on the market, and do not belong to the main technical problems solved in this technical solution, so they are not elaborated in this utility model.

[0025] Wherein, mounting side plates 51 are provided on both sides of the mounting seat 5, through holes 52 are provided at the corners of the mounting side plates 51, screws 521 are adapted to be inserted in the through holes 52, and the screws 521 are inserted into the first insulating block 411 and the second insulating block 421. By setting the mounting side plates 51 and the screws 521, the first insulating block 411 and the second insulating block 421 can be fixed, thereby the first resistor block 41 and the second resistor block 42 can be fixed, thereby the driving wheel 4 can be installed.

[0026] Among them, both sides of the outer side of the mounting seat 5 are inwardly provided with first electrical connection holes 61, and the first electrical connection holes 61 are opened to the wire 30. The first electrical connection holes 61 on the first resistor block 41 and the second resistor block 42 are adapted to be provided with first electrical connection rods 6, and the first electrical connection rods 6 extend through the first insulating block 411 and the second insulating block 421. By inserting the first electrical connection rods 6 on the first resistor block 41 and the second resistor block 42 into the first electrical connection holes 61, they can be electrically connected with the wire 30.

[0027] Among them, the first resistor block 41 is provided with a second electrical connection rod 7, which extends through the first insulating block 411, and the second resistor block 42 is adapted to be provided with a second electrical connection hole 71 corresponding to the second electrical connection rod 7. By inserting the second electrical connection rod 7 on the first resistor block 41 into the second electrical connection hole 71 on the second resistor block 42, the circuit connection between the first resistor block 41 and the second resistor block 42 can be achieved. When the assembly is completed, the current enters the first resistor block 41 through the first electrical connection rod 6 from the wire 30, and then enters the second resistor block 42 through the second electrical connection rod 7. Finally, the current returns to the wire 30 through another first electrical connection rod 6, so that the circuit connection can be achieved. At this time, the first resistor block 41 and the second resistor block 42 can be driven to heat up by the current, so that the driving wheel 4 can be heated.

[0028] Furthermore, by providing the first insulating block 411 and the second insulating block 421 , a short circuit due to direct contact can be avoided, thereby increasing the safety of the device when in use.

[0029] Among them, a first hydraulic component 11 is arranged on the frame 1 below the servo motor 21, a second hydraulic component 12 is arranged on the frame 1 below the driving wheel 4, a bracket is fixedly arranged on the top extension end of the second hydraulic component 12, a shaping wheel 22 is rotatably arranged on the bracket, and the shaping wheel 22 and the driving wheel 4 are arranged alternately in sequence. The top extension end of the first hydraulic component 11 is fixedly connected to the mounting frame on the servo motor 21, so that the servo motor 21 can be driven up and down by the first hydraulic component 11, so that the height of the driving wheel 4 on the rotating shaft 3 can be adjusted. The top extension end of the second hydraulic component 12 is fixedly connected to the bracket of the shaping wheel 22, so that the height of the shaping wheel 22 can be adjusted by the second hydraulic component 12. Therefore, the processing of the corrugated pipe can be realized by the coordinated arrangement of the driving wheel 3 and the shaping wheel 22.

[0030] It is worth noting that the specific structures of the first hydraulic component 11, the second hydraulic component 12, the working main machine 2, and the specific matching processing methods between the driving wheel 4 and the shaping wheel 22 are all existing technologies, which are all technologies disclosed in the comparative documents in the background technology and on the market. They are not the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0031] In this embodiment, when the user needs to replace the driving wheel 4, he only needs to remove the screws 521 on the mounting side plate 51 from the first insulating block 411 and the second insulating block 421 to remove the first resistor block 41 and the second resistor block 42.

[0032] Then the user takes out the new first resistor block 41 and the second resistor block 42, and inserts the first electrical connection rods 6 on them into the first electrical connection holes 61 opened on the mounting seat 5. During the insertion of the first electrical connection rods 6, the second electrical connection rods 7 on the first resistor block 41 will also automatically adapt and be inserted into the second electrical connection holes 71 on the second resistor block 42. At this time, the circuit connection in the first resistor block 41 and the second resistor block 42 can be completed, so that they can be heated, and the wall of the corrugated tube can be processed through them.

[0033] In the utility model, the heating of the driving wheel 4 can be realized by setting the wire 30, the first resistor block 41 and the second resistor block 42. The processing of the bellows can be realized by setting the driving wheel 4 and the shaping wheel 22. Since the driving wheel 4 is formed by splicing the first resistor block 41 and the second resistor block 42, the driving wheel 4 can be conveniently disassembled and replaced when it is worn due to long-term use, thereby avoiding the influence of the wear of the driving wheel 4 on the normal processing of the bellows.

[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.
