Description
Technical Field
The invention belongs to the technical field of metal surface additive machining, and particularly relates to dumbbell powder spraying additive machining equipment applied to dumbbell surface machining and a control system thereof.
Background
At present, the surface additive machining of the dumbbell is mainly realized by a plastic dipping mode, and the plastic dipping mode is also called plastic coating, hot dipping plastic and hot compress plastic coating. Plastic dipping or coating is a plastic coating process. According to the different raw materials used in plastic dipping, the plastic can be divided into liquid plastic dipping (coating) and powder plastic dipping (coating). The liquid plastic dipping process mostly adopts thermoplastic plastic dipping liquid, a thermoplastic plastic coating film has the characteristics of preheating, softening, cooling and curing to form a film, the physical melting plasticizing film forming process is mainly adopted, and the processing and the production are simpler. The most typical common polyvinyl chloride (PVC) plastic dipping liquid is prepared by mixing polyvinyl chloride (PVC) with more than 10 high-grade additives and synthetic raw materials of additives according to the strict proportion, and carrying out fine mixing and reaction refining.
However, the plastic dipping has the following disadvantages:
1. the baking temperature is high, sometimes affects the hardness of the workpiece or generates deformation, so that the high temperature (160-280 ℃) resistant workpiece is not suitable for adopting a plastic dipping processing technology.
2. Because the color of the coating needs to be changed by soaking and molding in the grooves, the product which requires frequent change of the color of the coating is not suitable for adopting a liquid soaking and molding processing technology.
3. Products which can not sink in the plastic dipping liquid are not suitable for the plastic dipping processing technology.
4. For cast iron workpieces with air holes in the matrix, the defects of bubbling and air holes are easy to generate during plastic dipping, so the cast iron workpieces cannot be subjected to plastic dipping.
5. The operation of large-scale workpieces is complex, and the quality of plastic coating is not easy to guarantee, so the plastic coating is not suitable for the integral or local plastic dipping of the large-scale workpieces.
6. The liquid plastic-dipped film is not suitable for products requiring thin film coating because of the large thickness of the film.
7. Needs preheating and curing, so the heat preservation equipment is more, the production line is long, and the occupied area is large.
Particularly, the problem that the liquid plastic-dipped film is large in thickness and is not suitable for products requiring thin film coating is that the thickness of the film of the product cannot be controlled, the shape of the product after forming cannot be controlled, and the quality of the product cannot be accurately controlled.
In summary, a dumbbell powder spraying additive processing device and a control system thereof are urgently needed to reduce the phenomena of large consumption and waste of plastic dipping liquid, shorten the length of a plastic dipping production line, solve the problem that the plastic dipping thickness cannot be controlled, and improve the appearance quality of products.
