Aluminum alloy flux-cored wire forming machine

Abstract

The invention discloses an aluminum alloy flux-cored wire forming machine which comprises a deforming device, a powder adding device, an opening closing device and a diameter reducing device. The deforming device is arranged on one side of the powder adding device; the opening closing device and the reducing device are arranged on the other side of the powder adding device in sequence; the deforming device is formed by combining two to four groups of adjacent vertical rollers; the opening closing device is formed by combining one to two groups of adjacent vertical rollers, one group of horizontal rollers and one group of vertical rollers, wherein the one group of horizontal rollers and the one group of vertical rollers are arranged behind the one to two groups of adjacent vertical rollers; and the diameter reducing device is formed by combining one to eight groups of horizontal rollers and one to eight groups of vertical rollers. The aluminum alloy flux-cored wire forming machine disclosed by the invention adopts a combining mode of centralized transmission and split transmission, can be used for manufacturing a high-quality aluminum flux-cored wire and a high-quality aluminum alloy flux-cored wire one time from an aluminum or aluminum alloy strip to welding powder to a finished product. By adoption of the aluminum alloy flux-cored wire forming machine, the production efficiency is increased, the quality of the flux-cored wire is improved, and the flux-cored wire manufacturing cost is lowered. The aluminum alloy flux-cored wire forming machine is a novel high-efficiency low-consumption energy-saving environmentally-friendly device for manufacturing the aluminum alloy welding material.

Description

technical field [0001] The invention relates to a welding wire forming machine, in particular to an aluminum alloy flux-cored welding wire forming machine. Background technique [0002] Aluminum and aluminum alloy flux-cored wire, including copper-aluminum flux-cored wire, aluminum-silicon flux-cored wire, aluminum-magnesium flux-cored wire, etc., as a new welding material, is widely used in the automotive field, such as water tanks, condensers and evaporators , used in industrial refrigeration, refrigeration and air conditioning, refrigerators, motors and transformers and other fields. Aluminum alloy flux-cored wire solves the ideal welding problem of replacing copper with aluminum in the above-mentioned industries. It has many advantages such as saving resources, energy, and environmental protection, and can bring huge economic and social benefits to users. However, at present, my country's aluminum and aluminum alloy flux-cored wire basically relies on imports from devel...

Problems solved by technology

Since the main component of the filler powder used in the production of aluminum alloy flux-cored wire is potassium fluoride, this powder has a light specific gravity and poor fluidity. The filler used in the carbon steel flux-cored wire is a mixture of metal and non-metal, and the specific gravity is relatively heavy. The powder barrel is large and the powder lowering part is relatively long. Powders with light specific gravity such as potassium fluoride are easy to stagnate in the lower sub-device and are not easy to be added to the aluminum alloy belt, so the filling rate cannot be guaranteed.

The traditional forming machine generally rolls between 8 and 12 passes, and cannot directly produce flux-cored wire products with specifications of 2.0, 1.8, and 1.6. Even if the forming machine is equipped with 24 passes, not only the cost is high, the energy consumption is large, and the equipment operation Complicated, especially after changing rolls, and not easy to adjust, seriously wasting production time
