AI Technical Summary
Existing nylon beads cannot be molded entirely from PEEK material, resulting in insufficient wear resistance and self-lubrication.
PEEK beads were prepared by mixing PEEK material with long fiber reinforced carbon fiber (long fiber glass fiber), granulating the mixture by heating it in a granulator, and then molding it in an injection molding machine by controlling the particle size, length and temperature parameters.
PEEK chain beads with excellent wear resistance and self-lubricating properties were successfully prepared, realizing the application of PEEK material in chains.
Abstract
Description
Technical Field
[0001] This invention relates to the field of chains, and more specifically to the production process of PEEK beads on chains. Background Technology
[0002] There is a nylon chain, and each link of the nylon chain is fitted with a nylon bead. The nylon bead is made of nylon. There is also a PEEK material. Using PEEK to make the bead can make the bead have better wear resistance and self-lubrication. However, using PEEK material to make the bead will make it difficult for the bead to be shaped well. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a production process for PEEK beads on a chain.
[0004] To solve the above problems, the technical solution adopted by the present invention is: a production process for PEEK beads on a chain, characterized by the following process steps: (1) Powdered PEEK material is metered and fed into the granulator, and long glass fibers are continuously cut into segments and fed into the granulator. The mass fraction of PEEK material is 65-75%, and the mass fraction of long glass fibers is 25-35%. (2) PEEK material and long fiber glass fiber are mixed in a granulator and heated to 380-400°C before granulation. The resulting particles have a particle size of 1.8-2.2 mm and a length of 2.8-3.2 mm. (3) Add the obtained particles to the injection molding machine, dry at 140-160℃, melt at 380-420℃, and then pour the molten material into the mold to form PEEK beads. The temperature of the mold is 160-200℃, the injection pressure is 75-85 MPa, the injection speed is 20-30%, and the beads are taken out of the mold after cooling for 40 seconds.
[0005] Furthermore, in the aforementioned production process of PEEK beads on the chain, the length of the cut long fiber glass is 0.1mm.
[0006] Furthermore, in the aforementioned production process of PEEK beads on the chain, the mass fraction of PEEK material is 70%, and the mass fraction of long-fiber glass fiber is 30%.
[0007] Furthermore, in the aforementioned production process of PEEK beads on the chain, the resulting particles have a diameter of 2mm and a length of 3mm.
[0008] Furthermore, the aforementioned production process for PEEK beads on the chain includes: adding the obtained particles into an injection molding machine, drying at 150°C, melting at 400°C, and then pouring the molten material into a mold to form PEEK beads. The mold temperature is 180°C, the injection pressure is 80 MPa, and the injection speed is 20-30%.
[0009] The advantages of this invention are: the production process of PEEK beads on the chain can effectively form PEEK beads, so that PEEK material can be applied to the beads of the chain. Detailed Implementation
[0010] The present invention will now be described in further detail with reference to specific embodiments.
[0011] The manufacturing process for PEEK beads on the chain is as follows: (1) Powdered PEEK material is metered and fed into the granulator, and long glass fiber is continuously cut into segments and fed into the granulator. The mass fraction of PEEK material is 70%, and the mass fraction of long glass fiber is 30%. (2) PEEK material and long fiber glass fiber are mixed in a granulator and heated to 400°C before granulation. The resulting particles have a diameter of 2 mm and a length of 3 mm. (3) Add the obtained particles to the injection molding machine, dry at 150°C, melt at 400°C, and then pour the molten material into the mold to form PEEK beads. The mold temperature is 180°C, the injection pressure is 80 MPa, the injection speed is 25%, and after cooling for 40 seconds, take it out of the mold. This is how PEEK beads are obtained.
[0012] To achieve better granulation, the length of the long-fiber glass fibers after cutting is 0.1mm.
