Fully-automatic nut welding system for production of special-shape heating tube assembly line

Abstract

The invention relates to a fully-automatic nut welding system for production of a special-shape heating tube assembly line. The fully-automatic nut welding system comprises a speed chain, a tool mechanism and a nut welding device, wherein the speed chain is used for conveying a clamped special-shape heating tube to a nut welding station, the tool mechanism is installed on the speed chain and positions and clamps the special-shape heating tube so that subsequent welding of a nut and the special-shape heating tube can be facilitated, and the nut welding device is installed on the speed chain and completes a series of automated operations of the nut including sorting, taking-out, clamping and welding. By means of the fully-automatic nut welding system, fully-automatic nut welding of the heating tube can be achieved, the working beat is accelerated, and manpower is saved. Corresponding electrode fixtures are adopted, a nut special for resistance welding is not necessarily needed, the cost can be saved, and the fully-automatic nut welding system meets various requirements of various heating tubes; and the fully-automatic nut welding system is simple in system structure and easy to operate and maintain.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a full-automatic nut welding system used in the production line of special-shaped heating tubes. Background technique [0002] Heating tubes are widely used in various fields. In order to meet different application requirements, heating tubes have different shapes. Due to the complexity and variety of heating tubes, it is difficult to realize automation in the production process. As far as the present is concerned, all aspects of the production of the heating tube are completed manually, especially welding nuts on the heating tube flange. At this stage, in other industries, such as the automobile production industry, the existing automatic nut welding technology can only be welded for special welding nuts. The nut welding of heating pipes has different requirements for nut types, and the shape of special welding nuts has certain limitations. The cost is high, and the space on t...

Problems solved by technology

At this stage, in other industries, such as the automobile production industry, the existing automatic nut welding technology can only be welded for special welding nuts. The nut welding of heating pipes has different requirements for nut types, and the shape of special welding nuts has certain limitations. The cost is high, and the space on the heating tube flange is very small, the existing fully automatic welding technology is not suitable for the heating tube production industry

At present, the welding of the heating pipe nut is completed by manual argon arc welding, which is time-consuming and labor-intensive.
