Description

Technical Field

[0001] This utility model relates to the field of wind turbine volute manufacturing technology, and in particular to a wind turbine volute forming device. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas; it is a type of driven fluid machinery. In China, "fan" is a common abbreviation for gas compression and gas transportation machinery. Commonly referred to as a fan, blower, or wind turbine, it is widely used for ventilation, dust removal, and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings; for ventilation and induced draft in boilers and industrial furnaces; and for cooling and ventilation in air conditioning equipment and household appliances. The volute casing is a common shell structure in fan construction. During processing, two side plates need to be welded to a bent steel plate. However, due to the elasticity of the steel plate itself and the stress generated during bending, the volute casing is prone to deformation during welding, leading to poor welding results and affecting the yield rate.

[0003] A search revealed a Chinese patent publication number CN219074014U, which discloses a fan volute and a volute plate forming device for the fan volute, including a left side plate, a right side plate, and a volute plate. The volute plate is connected to the left side plate and the right side plate by a biting method.

[0004] To address the issues in the aforementioned technologies where connections are made via snap-fit ​​mechanisms, requiring more bending of the steel plate and increasing processing difficulty, which is not conducive to rapid production in small factories, a fan volute forming device is proposed.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-5 As shown, a fan vortex casing forming device includes a processing plate 3 clamped inside a clamping shell 1 and a clamping shell 2. Multiple support wheels 13 are movably connected to the inner side of the processing plate 3. A support frame assembly is rotatably connected to one end of each support wheel 13. An unfolding motor 24 is fixedly connected to one end of the support frame assembly. One end of the unfolding motor 24 is fixedly connected to a swinging assembly. One end of the swinging assembly is fixedly connected to a support push rod 4. One end of the support push rod 4 is fixedly connected to the clamping shell 1.

[0031] The swing assembly includes a swing motor 22 and a swing link 23. One end of the swing motor 22 is fixedly connected to the movable end of the support push rod 4, one end of the swing link 23 is fixedly connected to the power output end of the swing motor 22, and the other end of the swing link 23 is fixedly connected to the unfolding motor 24.

[0032] After clamping shell 1 and clamping shell 2 are spliced ​​together, they can fit against the outside of the bent processing plate 3, which can fix the processing plate 3 from the outside to prevent shaking. At the same time, the support push rod 4 inserts the swing motor 22 and swing assembly into the inside of the bent processing plate 3 from one side. Then the unfolding motor 24 works to unfold the support frame assembly. Multiple support wheels 13 press against the inside of the processing plate 3 from the inside to further fix the processing plate 3. The swing motor 22 can adjust the position of the support wheels 13 to achieve better support, which can effectively prevent the processing plate 3 from twisting during welding. No additional bending is required on the processing plate 3, reducing the processing steps.

[0033] In this embodiment, the support frame assembly includes a fixed support frame 20, a middle support frame 12, and a rotating support frame 21. One end of the fixed support frame 20 is fixedly connected to the unfolding motor 24, one end of the rotating support frame 21 is fixedly connected to the power output end of the unfolding motor 24, and one end of the middle support frame 12 is rotatably connected to the power output end of the unfolding motor 24. A limit mechanism is movably connected between the fixed support frame 20, the middle support frame 12, and the rotating support frame 21.

[0034] The limiting mechanism includes a limiting groove 14 and a limiting rod 15. The limiting groove 14 is opened on one side of the fixed support frame 20, the middle support frame 12 and the rotating support frame 21. One end of the limiting rod 15 is fixedly connected to the fixed support frame 20, the middle support frame 12 and the rotating support frame 21 respectively, and the other end of the limiting rod 15 is movably connected to the limiting groove 14.

[0035] When the unfolding motor 24 rotates, it will drive the rotating support frame 21 to rotate. At this time, the rotating support frame 21 will drive the adjacent middle support frame 12 to rotate through the limiting rod 15 and the limiting groove 14 until the limiting rod 15 can no longer move, thus completing the limiting. It can be quickly unfolded to achieve support, and can also be stored and folded for easy removal after side plates are welded on both sides of the processing plate 3.

[0036] In this embodiment, one end of clamping shell 1 and clamping shell 2 has a mounting groove 16, and an electromagnet 17 is fixedly connected to the inside of the mounting groove 16. After the processing plate 3 is fixed by clamping shell 1 and clamping shell 2, the electromagnet 17 can be activated to further fix it and prevent shaking.

[0037] In this embodiment, a separation push rod 18 is fixedly connected to one end of the clamping shell 1, the movable end of the separation push rod 18 is fixedly connected to the clamping shell 2, and an anti-deviation rod 19 is fixedly connected to one end of the clamping shell 2, and the anti-deviation rod 19 is slidably connected to the clamping shell 1.

[0038] The telescopic release rod 18 facilitates the opening and closing of clamping shell 1 and clamping shell 2, while the anti-deviation rod 19 improves the stability of opening and closing.

[0039] In this embodiment: after clamping shell 1 and clamping shell 2 are spliced ​​together, they can fit against the outside of the bent processing plate 3, which can fix the processing plate 3 from the outside to prevent shaking. At the same time, the support push rod 4 inserts the swing motor 22 and swing assembly into the inside of the bent processing plate 3 from one side. Then the unfolding motor 24 works to unfold the support frame assembly. Multiple support wheels 13 press against the inside of the processing plate 3 from the inside to further fix the processing plate 3. The swing motor 22 can adjust the position of the support wheels 13 to achieve better support, which can effectively prevent the processing plate 3 from twisting during welding. There is no need to bend the processing plate 3, which reduces the processing steps.

[0040] When the unfolding motor 24 rotates, it will drive the rotating support frame 21 to rotate. At this time, the rotating support frame 21 will drive the adjacent middle support frame 12 to rotate through the limiting rod 15 and the limiting groove 14 until the limiting rod 15 can no longer move and the limiting is completed. It can be quickly unfolded to achieve support, and can also be stored and folded for easy removal after side plates are welded on both sides of the processing plate 3.

[0041] After the processing plate 3 is fixed in place by clamping shell 1 and clamping shell 2, electromagnet 17 can be activated to further fix it and prevent shaking. The extension and retraction of the separation push rod 18 can facilitate the opening and closing of clamping shell 1 and clamping shell 2. The anti-deviation rod 19 improves the stability of opening and closing.

[0045] The bending push rod 6 can extend and retract through the drive wheel 10 in conjunction with the bending wheel 8 to press the processing plate 3. When the bending motor 9 drives the drive wheel 10 to rotate, the processing plate 3 is bent. The feeding push rod 11 can adjust the position of the bent steel plate. After bending, it is immediately fixed and welded to reduce the possibility of deformation after relaxation.
