Background

The basic structure of a first CP-type single-screw prototype manufactured by Xinmaien (B.Zimmern) in France in 1960 consists of a cylindrical screw and 2 pairs of star wheels. The star wheel is floating. The star wheel is a star wheel body (generally made of metal) star wheel sheet (currently, the Chinese name of PEEK (polyetheretherketone) is common in China). The connection between the two star wheel plates is realized by a pin with an O-shaped ring, and after the floating star wheel is adopted, the elasticity of the O-shaped rubber ring is used for reducing the vibration clearance generated in the operation of the machine, so that the abrasion degree of the PEEK star wheel plate is not enough, and the abrasion generated in the operation of the star wheel plate for PEEK is very large because the screw rod is made of metal.

The molded line abrasion of the star wheel sheet in the long-term running process of the machine can cause gas leakage, so that the gas production rate of the machine is smaller and smaller along with the running of time. The star wheel sheet is required to be replaced at the moment when the gas using requirement of enterprises cannot be met. The material price of its star wheel piece is expensive, and what single screw compressor needs to solve at present is the wearing resistance of star wheel piece, life, and the highest consumptive material in the air compressor machine, and the solution is still urgent, and for the enterprise if the star wheel piece can operate for a longer time, the price/performance ratio that the enterprise produced just is higher, just also reduces and controls more costs. Therefore, a carbon fiber star wheel sheet manufacturing device is provided.

The embodiment of the utility model provides a carbon fiber star wheel piece making devices, carbon fiber star wheel piece have reached the stromatolite of high-quality through laser precision cutting carbon cloth, and carbon fiber is spread the technique and is developed rapidly these years, one of the compound material forming technology that production efficiency is the highest. The novel forming technology is generally applied to the aviation and aerospace industries, and is currently applied to a water lubrication air compressor, and the novel method for manufacturing the carbon fiber star wheel sheet sequentially comprises the steps of cleaning and preparing a mold, coating a hole sealing agent, coating a release agent on an adhesive sealing tape, cutting a carbon fiber fabric, sealing vacuum, sucking and injecting resin, curing, demoulding and post-treatment. The novel carbon fiber star wheel sheet adopts a novel high-temperature die pressing process. The carbon fiber high-temperature mould pressing process firstly cleans a mould to avoid dust and sundry residues, as shown in two pictures in figures 1 and 2, the carbon fiber high-temperature mould pressing process is a high-temperature mould pressing mould, firstly cleans an upper mould and a lower mould in figures 1 and 2 smoothly, and then coats the upper mould and the lower mould for demoulding and extrusion to prevent the product from being adhered with the mould too tightly after being formed. And then preparing carbon fiber prepregs for stacking layer by layer and performing pre-compaction. And (3) putting the stacked prepreg into a mould for mould assembly, and carrying out one-step molding at a certain time and temperature. As shown in figure 3, the lower die is provided with a heating pipe system which is externally connected with a constant temperature controller. Carbon fiber molding temperature control is particularly important, and typically the mold temperature is raised over a range of temperatures. The material has better fluidity and the crosslinking and curing speed is increased, but the too high temperature of the die in the carbon fiber compression molding can cause the premature initiation of the crosslinking reaction of the material and the too high curing speed. Resulting in inconsistent solidification of the inner and outer layers of the material in the mold cavity. The surface material is hardened first, and the low molecular substance generated by the cross-linking reaction is volatilized outwards when the inner layer is solidified. The carbon fiber product is swelled, cracked and warped, and has poor flowability and slow curing speed when the molding temperature is too low. The crosslinking reaction does not proceed sufficiently, resulting in too low strength and no gloss of the product. The strength and life requirements for the star wheel plate are great. The carbon fiber star wheel sheet has many excellent performances, and the carbon fiber has high axial strength and modulus, low density, no creep, non-oxidation environment, ultrahigh temperature resistance and good fatigue resistance. The coefficient of thermal expansion is small and has anisotropy. And the advantages are very suitable for the selection of the star wheel sheet of the single-screw air compressor, and are incomparable with PEEK star wheel sheets. The above embodiments are only for illustrating the concept of the novel process and the advantages of the novel process compared with other materials, and are more preferable embodiments of the screw air compressor.
