A water chamber welding platform

Abstract

The invention discloses a water chamber welding platform. The water chamber welding platform comprises a base, wherein a rotary bearing is arranged on the base; an upright post is fixed on the rotary bearing; two supporting plates are arranged on the upright post; a main piece groove for accommodating a radiator core is formed between the two supporting plates; cylinders are arranged on the upright post above supporting plates; pressure blocks are fixed on end parts of piston rods of the cylinders; the cylinders are communicated with a two-position four-way side exhaust valve; the two-position four-way side exhaust valve is communicated with a rotary pneumatic connector. Multiple cores can be welded at the same time in a centralized way, so that the labor productivity is improved; the two-position four-way side exhaust valve controls lifting and falling of the cylinders to prepress the cores and a water chamber, thus preventing damage to the water chamber, ensuring the welding quality, improving the welding reliability, reducing the using amount of valuable tin-lead solder and reducing the production cost; the rotary pneumatic connector is fixed on the top of a main intake pipe, an external gas source is connected to the rotary pneumatic connector, and independent rotation is formed at the rotary pneumatic connector, so as to avoid reverse interference of a PU (polyurethane) gas pipe during rotation of the upright post and ensure continuous and unlimited rotation of the upright post.

Description

technical field [0001] The invention relates to a welding device, in particular to a water chamber welding platform, which belongs to the technical field of heat exchangers. Background technique [0002] In the copper heat sink, when the upper and lower water chambers are connected to the main piece of the core body, except for a part connected by bolts and gaskets, the other part is welded by flame brazing with lead-tin solder. [0003] At present, in the production process of the copper heat sink, when the main sheet is aligned, the core needs to be placed on the ground, and the main sheet is manually aligned, and the work efficiency is low. When the water chamber is fixed, put the water chamber in the groove of the main piece as required, and manually adjust the welding gap, which will easily cause deformation of the workpiece and lead to uneven welding gap; when flame brazing, it is generally carried out without pre-compression force Welding is prone to welding deformat...
