Description

Technical Field

[0001] This utility model belongs to the field of solar energy technology, and specifically discloses a riveting and pressing device for the outer shell of a solar water tank. Background Technology

[0002] A solar water heating system is a device that uses solar collectors to collect solar radiation energy to heat water. It is currently the most economically valuable, technologically mature, and commercially viable application of solar thermal energy. A solar water heating system consists of a collector, an insulated water tank, connecting pipes, a control center, and a heat exchanger. The solar insulated water tank is a device used in centralized solar water heating or solar heating projects to collect and store the hot water generated by the collector. A solar insulated water tank generally consists of an inner tank, an insulation layer, and an outer shell. Existing solar water tank shells are cylindrical. During production, a bending machine is used to bend opposite edges of two sheets of material. After bending, the sheets are transported to a riveting and tenoning machine, where the bent portions of the two sheets are riveted together. This process involves four bends and two tenons. Existing solar water tank shell production lines require two machines, occupy a large area, have low production efficiency, often lead to product accumulation, and frequently cause errors in the riveting direction due to the need to flip the sheets during production.

[0022] This utility model relates to a riveting and tenoning device for the outer shell of a solar water tank. It integrates a bending unit and a riveting unit.

The top of the vertical section of the left pressure plate 1 and the right pressure plate 13 is fixedly connected to the end of the corresponding cylinder push rod. The cylinder is fixedly connected to the upper base 2. Under the action of the cylinder, the horizontal sections of the left pressure plate 1 and the right pressure plate 13 can rise and fall vertically relative to the riveting lower mold 4. When riveting the bent portion of the plate, the left pressure plate 1 and the right pressure plate 13 descend respectively, pressing the corresponding plate, thus completing the riveting. The upper mold 3 descends to press and tighten the lower mold 4, thus riveting the bent parts of the two plates. Then, the left pressure plate 1 and the right pressure plate 13 rise respectively to release the corresponding plates. The riveting upper mold 3 rises away from the riveting lower mold 4. The two plates are manually rotated to rotate the other bent part of the two plates onto the riveting lower mold 4. The left pressure plate 1 and the right pressure plate 13 descend again to press and tighten the corresponding plates. The riveting upper mold 3 descends again to press and tighten the lower mold 4, thus riveting the other bent part of the two plates. The left pressure plate 1 and the right pressure plate 13 rise respectively to release the corresponding plates. At the same time, the riveting upper mold 3 rises away from the riveting lower mold 4. Finally, the riveted solar water tank shell can be pulled out from the suspended end of the lower base 9. The production is convenient and efficient.

[0024] As an optional design, the preferred riveting and pressing device for the solar water tank shell has a lifting component between the riveting upper mold 3 and the upper base 2. Under the action of the lifting component, the riveting upper mold 3 can be lowered to press against the riveting lower mold 4 or raised away from the riveting lower mold 4 to achieve riveting.

[0025] As an optional design, the preferred method is the riveting and pressing device for the outer shell of the solar water tank, with the upper riveting mold 3 and the lower riveting mold 4 respectively arranged along the length direction of the outer shell of the water tank.

[0026] As an optional design, the preferred method for riveting and pressing the solar water tank shell is to connect a downwardly extending spring column to the bottom of the riveting lower mold 4 via a spring upper baffle 12. A compression spring 8 is fitted on the spring column, and a column hole is provided on the lower base 9 at a position corresponding to the spring column. The lower ends of the spring column and the compression spring 8 extend into the column hole respectively, and the lower end of the compression spring 8 is fixedly connected to the lower spring fixing plate 7 located below the lower base 9.

[0027] As an optional design, the preferred method for riveting and pressing the solar water tank shell is to have matching concave and convex structures on the opposite surfaces of the upper and lower bending dies. During bending, the upper bending die descends and cooperates with the lower bending die to bend the edge of the plate.

[0028] The working process of this utility model is as follows:

[0029] like Figure 2As shown, there are staff members on duty on the left and right sides of the riveting lower die 4. First, the first edge to be bent of the first plate 14 is placed between the left bending upper die 5 and the left bending lower die 6, and the first edge to be bent of the second plate 15 is placed between the right bending upper die 11 and the right bending lower die 10. The riveting upper die 3 descends and presses the riveting lower die 4. Under the action of the compression spring 8, the riveting lower die 4 descends relative to the lower base 9, while driving the left bending upper die 5 and the right bending upper die 11 to descend. The left bending upper die 5 and the left bending lower die 6 cooperate to complete the bending of the first edge to be bent of the first plate 14, and the right bending upper die 11 and the right bending lower die 10 cooperate to complete the bending of the first edge to be bent of the second plate 15.

[0030] like Figure 3 As shown, the worker on the right then holds the second plate 15 and passes it through the gap between the riveting upper die 3 and the riveting lower die 4 to the worker on the left side of the riveting lower die 4. The worker on the left receives the second plate 15 and places the second edge of the second plate 15 to be bent between the left bending upper die 5 and the left bending lower die 6 to complete the second bending of the second plate 15. At the same time, the worker on the left holds the first plate 14 and passes it from below the lower base 9 to the worker on the right side of the riveting lower die 4. The worker on the right holds the first plate 14 and places the second edge of the first plate 14 to be bent between the right bending upper die 11 and the right bending lower die 10 to complete the second bending of the first plate 14.

[0031] like Figure 4 As shown, the second bends of the first plate 14 and the second plate 15 are placed on the riveting lower die 4. The left pressure plate 1 and the right pressure plate 13 descend respectively, pressing the corresponding plates together. The riveting upper die 3 descends to press the riveting lower die 4, thus riveting the second bends of the two plates together. Then, the left pressure plate 1 and the right pressure plate 13 rise respectively, releasing the corresponding plates. At the same time, the riveting upper die 3 rises away from the riveting lower die 4. The two plates are then manually rotated counterclockwise. Figure 5 As shown, the first bent portion of the two plates is rotated onto the riveting lower mold 4. The left pressure plate 1 and the right pressure plate 13 descend again to press the corresponding plates together. The riveting upper mold 3 descends again to press the riveting lower mold 4 together to achieve the riveting of the first bent portion of the two plates together. The left pressure plate 1 and the right pressure plate 13 rise again to release the corresponding plates. At the same time, the riveting upper mold 3 rises away from the riveting lower mold 4. Finally, the riveted solar water tank shell can be pulled out from the suspended end of the lower base 9. The production is convenient and efficient.
