[0020] A forming die for a water heater panel with the above structure. When in use, the user places the plate on the concave flanging die core 5 above the lower die 2. When the external hydraulic equipment drives the upper die 1 to move downward, the convex flanging die core 4 fixedly arranged on the backing plate 3 moves downward to press the plate. The four sides of the plate are flanged upward through the concave flanging die core 5. At the same time, the convex punching die core 6 on the backing plate 3 punches the concave punching die core 7, so that a display hole is opened on the plate. After punching, the stripper plate 9 pushes the plate upward through the built-in resilient material and limits the resilient stroke of the stripper plate 9 through the resilient limiting part 100. The pressure plate 8 also presses the plate tightly on the stripper plate 9 during stamping through the resilient material. At the same time, the moving mechanism 400 drives the cushioning part 300 to move toward the concave flanging die core. At this time, the plate is clamped on the convex flanging die core 6 due to flanging, and the plate is pushed downward through the stripping part 200, and the plate falls on the cushioning part 300. Compared with the prior art, it can flange and punch the plate at the same time, prevent the surface of the plate from being scratched, and improve the production quality.

[0021] As Figure 3 shown, in some embodiments of the present invention, in order to respectively limit the pressure plate 8 and the stripper plate 9, the resilient limiting part 100 includes a plurality of through holes 101 penetrating through each of the backing plates 3. A plurality of limiting sleeves 102 are sleeved around the periphery of the pressure plate 8. A first counterbore groove 103 is penetrated through both the upper die 1 and one of the backing plates 3. A first bolt 104 is arranged in each of the first counterbore grooves 103. Each of the first bolts 104 is in threaded cooperation with the adjacent limiting sleeve 102. A second counterbore groove 105 is penetrated through both the lower die 2 and the other backing plate 3. A guide sleeve 106 is arranged in each of the second counterbore grooves 105. A second bolt 107 is movably inserted into each of the guide sleeves 106. Each of the second bolts 107 is in threaded cooperation and arranged below the stripper plate 9.

[0022] When a forming die for a water heater panel with the above structure is in operation, during the process of manufacturing the die, the user can place resilient springs or urethane rubber in the through holes 101 of each backing plate 3. After the convex flanging die core 4 and the convex punching die core 6 respectively flange and punch the plate, the stripper plate 9 located in the concave flanging die core 5 pushes the plate upward through the resilient spring. At the same time, the second bolt 107 located in the second counterbore groove 105 also moves upward through the guide sleeve 106. Since the second bolt 107 is in threaded cooperation and arranged below the stripper plate 9, after the stripper plate 9 moves to a certain position, the second bolt 107 is clamped at the counterbore of the second counterbore groove 105. The pressure plate 8 in the convex flanging die core 4 is pressed downward through the resilient spring, so that the plate is always under the pressure of the pressure plate 8 during stamping to prevent deformation. The downward pressing distance of the pressure plate 8 is limited by the first bolt 104 in threaded cooperation with the limiting sleeve 102, and the first bolt 104 is clamped at the counterbore of the first counterbore groove 103.

[0023] As Figure 3 and 4 shown, in some embodiments of the present utility model, in order to achieve the effect of pushing the plate downward, the material discharging portion 200 includes a U-shaped material discharging plate 204 disposed outside the convex punching die core 6.

Each hanging rod 202 is sleeved on the U-shaped material discharging plate 204. A plurality of tension springs 203 are connected between the U-shaped material discharging plate 204 and the upper die 1. An inclined block 205 is fixed in the middle of the U-shaped material discharging plate 204. A push rod motor 206 is fixed below the upper die 1. A slider 207 capable of fitting with the inclined block 205 is fixed at the output end of the push rod motor 206.

[0024] When a water heater panel forming die with the above structure is in operation, the slider 207 fixed at the output end of the push rod motor 206 is driven to move by the push rod motor 206, so that the inclined block 205 drives the U-shaped material discharging plate 204 to move downward. When the U-shaped material discharging plate 204 moves, it moves through the hanging rod 202 in the guiding hole 201. Finally, the U-shaped material discharging plate 204 is reset by a plurality of tension springs 203 connected between it and the upper die 1.

When it moves under the plate, the flap pieces 304 symmetrically fixed at the rear side of the receiving plate 302 are blocked on the blocking shafts 305 symmetrically fixed on the right side of the support table 10, restricting the moving distance of the receiving plate 302.

[0027] As Figure 4As shown, in some embodiments of the present utility model, in order to achieve the effect of driving the cushioning part 300 to move towards the concave flanging die core 5, the moving mechanism 400 includes a through groove 401 penetrating through the middle of the support table 10. Below the through groove 401 and symmetrically fixed below the support table 10 are mounting plates 402. Between the mounting plates 402 are symmetrically sleeved with rollers 403. Between the rollers 403 is sleeved and connected with a synchronous belt 404. On the synchronous belt 404 are provided a plurality of protruding ribs 405 at intervals. Below the material receiving plate 302 are provided a plurality of grooves 406 at intervals. Each of the protruding ribs 405 can be engaged in the grooves 406. Fixed to the sleeved end of one of the rollers 403 is a first spur gear 407. Fixed below the support table 10 is a motor 408. Fixed to the output end of the motor 408 is a second spur gear 409. The second spur gear 409 and the first spur gear 407 are meshed with each other.

[0028] When a water heater panel forming die with the above structure is in operation, the motor 408 drives the second spur gear 409 to rotate. When the second spur gear 409 rotates, it drives the first spur gear 407 to rotate. When the first spur gear 407 rotates, one of the rollers 403 drives the other roller 403 to rotate through the synchronous belt 404. When the synchronous belt 404 rotates, the plurality of protruding ribs 405 thereon are engaged with the grooves 406, so that the material receiving plate 302 moves along the slide rail 301.
