Description

Technical Field

[0001] The utility model belongs to the technical field of metal stamping parts, in particular to a stacked grid part of a stamped fire grate. Background Art

[0002] Gas water heaters operate by heating water continuously flowing through a coil through combustion, bringing the cold water to the desired temperature. A core component in a gas water heater is the fire grate, which mixes the gas and air, burns the gas, and transfers the heat generated by the combustion to a heat exchanger. Fire grate is typically made of high-temperature-resistant stamped metal, which can accommodate the complex shapes required.

[0003] The existing stacked grille parts of stamped fire grates still have some defects. After the stamping is completed, the joints of the plates are mostly fixed by welding. The fixing method is relatively simple and it is easy to loosen over time, causing damage to the grille parts and making it inconvenient to use. For this reason, we propose stacked grille parts of stamped fire grates. Utility Model Content
