Electric Water Heater Production Line
Please find the video at: /watch?v=708VMKiukoo
Outer tank inward bending machine used to process the outer tank of electric water heater. This machine finish the inward bending of outer tank two ends.
Effieiency: nacking 5/6 pieces per minute.
Includ: two same machines. One necking/inward bending one end and the other necking the other end.
| Process parameters | ||
| 1 | Applicable product | Electric water heater shell necking (including inward connecting method). |
| 2 | Power | 415V,3L/N/PE,50 Hz. |
| 3 | Driving power | All feeding mechanisms adopt servo motors |
| 4 | Ambient Condition | -5°C~+45°C, workpiece is with normal temperature |
| 5 | Applicable material | δ0.4~0.6mm CRC |
| 6 | Applicable Shell length | 350mm~1400mm |
| 7 | Applicable Shell diameter | φ310~500mm |
| 8 | Provided necking expand core size | Φ310,φ360,φ410,φ460 |
| 9 | Logistics lines before and after the machine | Conveyer which matching previous welding equipment, and conveyer which connecting next punching step. |
| 10 | Equipment housing construction | Adopts whole steel welded construction for housing. The housing has been carry out heat treatment after finish welding which brings enough strength and hardness, the machining after that can provide good accuracy. |
| 11 | Equipment housing construction | After tightened the expand cord radial runout ≤0.15mm, can ensure diameter size shiftable, accuracy will be repeated. |
| 12 | Shell barrel appearance requirement | Barrel will be deformed by the expand core after necking process. The shell surface will not be deformed after all process steps. . |
| 13 | Necking area appearance requirement. | Free of any wave folding shape, no any repair required after process (Applicable for 0.6mm and 0.4mm sheet). |
| 14 | Design speed | 3pcs/min (calculate based on Φ410 * 600 * 0.6mm Shell, suitable for both inward & outward joint connecting). |
| 15 | Life of necking blade | Necking blade working life is no less than 600K cycles |
| 16 | Dimension accuracy requirement | Necking dimension should satisfy drawings, should ensure dimension stable, accuracy ≤ ±0.3mm, length tolerance ≤ ±1mm |
| 17 | Convey system | Workpiece logistics will be done automatically, including workpiece clamp and feed in, reverse and turnover, before&after steps connecting, no manual operation required (exclude people to monitor) |
| 18 | Critical necking rotate blade and expand core already have racing protection, can be racing. Process chamber is sealed completely, but can be monitored through transparent window; configured Photoelectric automatic protection function. | |
| 19 | Operation method | Provide manual and automatic two working modes |
| 20 | Operation description | The machine is configured HMI function, all parameters can be set on HMI as per actual requirement; can finish different workpiece shift setting on HMI except expand core change. |
| 21 | Equipment maintainability | With Fault self-test function, have enough maintain space, components are easy to be disassembled. |
| 22 | Fixture change | Two trained workers can finish different diameter&length necking fixture (necking blade and expand core) change within 20mins |
| 23 | Machine dimension | Working table height: 700-800mm. Match with Hanyan’s equipment |
