Abstract
In the paper are presented elements of the deburring technology of rubber or plastic parts in cryogenic conditions. There is a proposal for deburring equipment that follows: simplicity in use, increased production capacity and reduced consumption of liquid nitrogen. The heat transfer through the insulating layer is calculated using several types of thermal insulation: perlite powder, spray-on polyurethane foam and aerogel blanket. The obtained results are used for the design of a cryogenic deburring equipment where the thermal transfer is minimal.
Highlights
The use of plastics and composites in the current era is due to their important advantages such as superior characteristics of corrosion resistance, ease of processing or low density and weight
The goal of the deburring process is to clean the parts from the burrs that have appeared on their surface during the manufacturing process
For the equipment designed and presented in the paper, three types of insulators were chosen (Aerogel Blanket, Spray-On Polyurethane Foam, Perlite Powder) [4] for which the liquid nitrogen flow rate is calculated according to the wall thickness
Summary
The use of plastics and composites in the current era is due to their important advantages such as superior characteristics of corrosion resistance, ease of processing or low density and weight. They are successfully replacing metallic materials whose processing is difficult and expensive. The use of cryogenic deburring technology leads to clean the interior and exterior burrs of the parts, in a much shorter time and with a higher quality than by using other methods. The cryogenic deburring equipments have several elements, necessary for the thermo-mechanical process.
