Radial extruding forming device of cut-fiber reinforcement rubber composite material

Abstract

The invention relates to a radial extrusion molding device for the composite material of short fiber reinforced rubber, in particular to a device for realizing the radial direction of short fiber in rubber material. Eight threaded holes are produced on the front side of the flange of the device, eight double threaded screws and nuts are used for connecting the flange, a flow channel plate, a blocking supporting plate, a shaping plate and a machine head pressing plate into a whole in sequence, a rubber overflow valve is installed above the flange, and a threaded hole is drilled under the flange to install a pressure sensor; a pair of blocking adjusting blocks is positioned in the middle of the blocking supporting plate, one end of a blocking adjusting bolt is fixed with the blocking adjusting blocks, the other end thereof is connected with the blocking supporting plate through thread, and the blocking adjusting bolt is used for controlling the blocking gap; a pair of shaping adjusting blocks is positioned in the middle of the shaping plate to adjust the shaping gap, the shaping adjusting blocks are clamped between the blocking supporting plate and the machine head pressing plate and fixed through screws. The device has the advantages of simple structure, reliable principle, broad application range, low cost, good production efficiency, high product quality and stable performance.

Description

Technical field:

[0001] The invention relates to a radial orientation extrusion molding device for short fiber reinforced rubber composite materials, in particular to a continuous extrusion molding of short fiber reinforced rubber which realizes radial orientation extrusion molding of short fibers in rubber materials during the extrusion process installation. Background technique:

[0002] Short fiber-rubber composites are one of the ideal materials for preparing high-performance tires. Studies have found that adding short fibers to the rubber compound can significantly reduce the rolling resistance, wet skid resistance and hysteresis loss of the tire, and improve the tear resistance and chipping resistance of the tread, which can reduce the weight of the tire and make the tire more durable. Driving noise is reduced. If the short fibers are radially oriented in the rubber compound, the overall rigidity of the tire can be improved, and the balance handling, ride comfort and...
