An intelligent double-layer fixed exothermic welding mold to improve product qualification rate

Abstract

The invention discloses an intelligent double-layer fixed exothermic welding mold for improving the qualified rate of products. Its structure includes a clamping handle and a mold body. The clamping handle is locked with the mold body. Composed of opening and closing clamps, the handle is connected with the closing clamp shaft, and the opening and closing clamps are locked. The opening clamp includes the upper shaft pendulum, the bobbin, and the lower shaft plate. In the present invention, the copper bar is placed in the mold body, the copper bar joint is placed in the center of the mold body, the gasket is put in, molten powder is poured in, and the ignition gun is used to ignite the ignition powder after the top cover is covered; the thermal induction drives the operation of the bobbin device, After the inner shaft rotates for a few seconds, the inner mold device is driven to run. The copper bars are bound and fixed by the inner mold strips, and the mold frame is assisted in fixing, which not only realizes the fixation but also heats up through the waste heat of the mold frame, ensuring the appearance and quality of the shape and size of the welding tools. , It also reasonably controls the welding time, avoiding the situation that the solder joints stick to the mold for too long, resulting in the scrapping of the mold.

Description

technical field [0001] The invention relates to the field of moulds, in particular to an intelligent double-layer fixed exothermic welding mould, which improves the qualified rate of products. Background technique [0002] Exothermic welding is a simple, high-efficiency, high-quality metal joining process. It uses the chemical reaction heat of metal compounds as a heat source, and conducts heating operations directly or indirectly through superheated molten metal. A certain shape and size are formed in the cavity to meet the requirements of the project. It is most suitable to wait 15-20 seconds before opening the exothermic welding mold. [0003] Although the structure of the prior art makes the processing of the exothermic welding device easier, the solder joints may stick to the mold if the welding is completed for a long time during use, and the mold weld joints sticking will cause the mold to be scrapped. If the time is not controlled If it is not good, remove the weldi...

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art, to provide an intelligent double-layer fixed exothermic welding mold that improves the product qualification rate, to solve the problem that although this structure makes the processing of the exothermic welding device simple If the welding time is too long during use, the solder joints may stick to the mold. If the mold welding mouth sticks, the mold will be scrapped. If the time is not controlled properly, the welding tool will be removed, which will lead to unsightly shape and size of the welding tool and poor quality. But off the question
