Description

TECHNICAL FIELD

[0001] The utility model relates to metal plating technology field especially relates to a metal plating drying furnace. BACKGROUND

[0002] Metal plating is also called chemical plating, which is to coat a layer of metal film on the surface of metal. Through the coating film, the performance of the metal in anti-flow, low temperature rise and anti-aging can be improved. After the metal is plated, it needs to be dried by a drying furnace, which can make the plating effect better.

[0003] After searching, the patent with publication number CN219923561U discloses a metal plating drying furnace. The metal after plating is placed on the support seat above the installation placement rack, then the sealing box door is closed, and then the hot air box is opened for drying. The heated hot air enters the inside of the box body and is discharged from the exhaust seat, which causes the heat of the heated air to be wasted, so the entire drying process needs to keep the heating mechanism working all the time, resulting in high energy consumption of the drying furnace. Secondly, the placement rack is directly fixed in the box body by screws. When taking and placing the metal parts, they need to be taken one by one, which results in a long time for taking and placing the metal parts. The box door needs to be opened during the entire process, and the heat in the box body will be completely lost. The subsequent drying needs to be reheated, which will increase the energy consumption. Therefore, it needs to be further improved. UTILITY MODEL CONTENT
