Technical Field

The invention relates to a special die for a sports parallel bar lever capable of automatically adjusting the position of a coated cloth bucket, and belongs to the technical field of sports parallel bar lever equipment processing equipment.

Background

The glass fiber lever is a composite material which uses glass fiber as a reinforcing material and synthetic resin as a base material, and the glass fiber and the synthetic resin are bonded together to form a rigid rod product with a fixed shape, which can bear tensile stress and bending, compression and shearing stress. The existing processing technology is to produce the glass fiber reinforced plastic pultrusion sections with different shapes according to a die with a certain section shape. The glass fiber reinforced plastic product has the characteristics of high strength, corrosion resistance, high temperature resistance and the like, and the glass fiber is an inorganic non-metallic material with excellent performance and has the advantages of good insulativity, strong heat resistance, good corrosion resistance and high mechanical strength. The novel hair-dyeing and-weaving process is characterized in that glass balls or waste glass is used as a raw material and is manufactured through processes of high-temperature melting, wire drawing, winding, weaving and the like, the diameter of each monofilament ranges from several micrometers to twenty-several-meter micrometers, the diameter of each monofilament is equivalent to 1/20-1/5 of one hair, and each bundle of fiber precursor consists of hundreds of monofilaments and even thousands of monofilaments. The sports equipment formed by drawing and winding the glass fiber has strong heat resistance and good corrosion resistance, and the mechanical strength is superior to that of the conventional metal, plastic and wooden materials, so the sports goods made of the glass fiber reinforced plastic material are widely used.

The cross section of the parallel-bar lever is made into an oval shape (like the cross section shape of a vertical egg) with a large circle tangent to a small circle for the comfortable holding of athletes, and the fatigue test of the parallel-bar lever produced by the conventional stretch-wrap die shows that reticulation appears in small diameter measurement when 2 ten thousand times of fatigue occurs but the mechanical performance is not influenced; when the number of the cracks reaches 5 ten thousand, the small diameter side has obvious cracks, and the service life is not ideal enough.
