DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below in conjunction with the drawings and the detailed description of the embodiments:

[0019] As Figures 1 to 4 shown, a bending device for a water heater panel, characterized by comprising: a bottom plate 1, reinforcing ribs 13 are provided on each of the bottom plates 1, a plurality of support rods 12 are fixed between the bottom plate 1 and the base 2, a base 2 is provided above the bottom plate 1, a lower die 3 is fixed above the base 2, a support frame 4 is fixed on the front side of the lower die 3, a counterbore 5 is provided around the lower die 3, a first lower bending die core 6 is provided on each of the counterbores 5, a stripping plate 7 is provided above the lower die 3, second lower bending die cores 8 are provided on the left and right sides of the lower die 3, a first upper bending die core 9 is provided below the support frame 4, a placement groove 10 is provided in the middle of the first upper bending die core 9, a second upper bending die core 11 is provided in the placement groove 10, a driving mechanism 100 capable of driving the first upper bending die core 9 and the second upper bending die core 11 to move downward is provided above the support frame 4 and the first upper bending die core 9, a first moving mechanism 200 capable of driving the second lower bending die core 8 to move upward is provided on the left and right sides of the bottom plate 1, and a second moving mechanism 300 capable of driving the stripping plate 7 to move upward is provided in the middle of the bottom plate 1.

[0020] For a bending device for a water heater panel with the above structure, when in use, the user places the water heater panel above the first lower bending die core 6 and the second lower bending die core 8 on the counterbore 5. At this time, the driving mechanism 100 drives the first upper bending die core 9 provided below the support frame 4 to move towards the water heater panel, so that the first upper bending die core 9 initially bends the periphery of the water heater panel on the first lower bending die core 6 and the second lower bending die core 8. Then, the driving mechanism 100 presses the second upper bending die core 11 provided in the placement groove 10 downward, and the first upper bending die core 9 moves upward by a distance through the driving mechanism 100, so that the heights of the first upper bending die core 9 and the second upper bending die core 11 are inconsistent. Then, the first moving mechanism 200 drives the second lower bending die core 8 to move upward, so that the second lower bending die core 8 cooperates with the second upper bending die core 11 to bend the left and right sides of the water heater panel upward again to form a hem. Then, the driving mechanism 100 moves the second upper bending die core 8 upward, and at the same time drives the stripping plate 7 to move upward through the second moving mechanism 300 to complete the material stripping. Compared with the prior art, it can automatically process the water heater panel into a hem in one time, reducing the processing cost.

[0021] As Figure 3As shown, in some embodiments of the present utility model, in order to achieve the effect of driving the first upper bending die core 9 and the second upper bending die core 11 to move downward, the driving mechanism 100 includes a first hydraulic cylinder 101 fixed above the support frame 4. The output end of the first hydraulic cylinder 101 passes through the support frame 4 and is fixed to the first upper bending die core 9. Second hydraulic cylinders 102 are symmetrically fixed above the second upper bending die core 11, and the output ends of the second hydraulic cylinders 102 pass through the first upper bending die core 9 and the second upper bending die core 11 and are fixedly connected.

[0022] When a water heater panel bending device with the above structure is in operation, the first upper bending die core 9 moves downward through the first hydraulic cylinder 101, so that the first upper bending die core 9 can move towards the water heater panel. During the secondary bending, the second upper bending die core 11 is first pressed downward through the second hydraulic cylinder 102, and the first upper bending die core 9 moves upward by a certain height through the first hydraulic cylinder 101 to provide a clearance position for the secondary bending of the water heater panel. When the first upper bending die core 9 moves upward, the second hydraulic cylinder 102 moves the second upper bending die core 11 downward synchronously.

[0023] As Figure 3 and 4 As shown, in some embodiments of the present utility model, in order to achieve the effect of driving the second lower bending die core 8 to move upward, the first moving mechanism 200 includes first motors 201 symmetrically fixed on the bottom plate 1. A first screw rod 202 is fixed to the output end of the first motor 201. Guide sleeves 203 are fixed on the left and right sides of the bottom plate 1. Guide rods 204 are movably inserted into each of the guide sleeves 203. A support seat 205 is connected and fixed between every two symmetrically arranged guide rods 204. A connecting plate 206 is fixed on the support seat. Slots 207 are provided on the left and right sides of the lower die 3. The connecting plate 206 is movably arranged in the slots 207. Each of the second lower bending die cores 8 is respectively connected and fixed to the adjacent connecting plate 206. A first thread sleeve 208 is fixed in the middle of each of the support seats 205, and the first thread sleeve 208 is in threaded cooperation with the first screw rod 202.

[0024] When a water heater panel bending device with the above structure is in operation, the output end of the first motor 201 drives the first screw rod 202 to rotate, so that the first screw rod 202 drives the first thread sleeve 208 to rotate and move upward when rotating. At this time, the first thread sleeve 208 drives the support seat 207 to move upward, so that the support seat 207 drives the connecting plate 206 to move upward. While the connecting plate 206 is moving, the guide rod 204 moves upward along the guide sleeve 203, and the connecting plate 206 drives the second lower bending die core 8 to move upward.

[0025] As Figure 3 and 4As shown, in some embodiments of the present utility model, in order to achieve the effect of driving the stripping plate 7 to move upward, the second moving mechanism 300 includes a second motor 301 fixed above the bottom plate 1. A first straight gear 302 is fixed to the output end of the second motor 301. A rotating sleeve 303 is fixed to the middle of the bottom plate 1. A rotating shaft 304 is movably sleeved in the rotating sleeve 303. A second straight gear 305 is fixed above the rotating shaft 304. The second straight gear 305 meshes with the first straight gear 302. A second screw rod 306 is fixed above the second straight gear 305. A second threaded sleeve 307 is fixed to the middle of the stripping plate 7. The second screw rod 306 is in threaded cooperation with the second threaded sleeve 307. Guide columns 71 are fixed around the stripping plate 7. Insertion holes 72 are provided around the lower die 3. The guide columns 71 are movably inserted into the insertion holes 72. A through groove 73 is provided in the middle of the lower die 3. The second threaded sleeve 307 is movably arranged in the through groove 73.

[0026] When a water heater panel bending device with the above structure is in operation, the second motor 301 drives the first straight gear 302 to rotate. When the first straight gear 302 rotates, it drives the second straight gear 305 to rotate. When the second straight gear 305 rotates, it drives the rotating shaft 304 to rotate in the rotating sleeve 303. At the same time, the second straight gear 305 drives the second screw rod 306 to rotate. When the second screw rod 306 rotates, it drives the second threaded sleeve 307 to rotate and move upward. When the second threaded sleeve 307 moves, it drives the stripping plate 7 to move upward. The stripping plate 7 moves along the insertion holes 72 through the guide columns 71 fixed around it, and the second threaded sleeve 307 moves along the through groove 73 provided in the middle of the lower die 3.
