CT slip ring conductive disc forming method

Abstract

The invention discloses a CT slip ring conductive disc forming method. The method comprises the steps of (1) preparing a conductive disc mold; (2) turning a copper plate ring groove on an annular copper plate at one time, and putting the annular copper plate into the conductive disc mold; (3) preparing a pouring material; (4) dividing the material into a component A and a component B; (5) respectively adding the component A and the component B into static mixing vacuum pouring equipment to be heated, stirred and subjected to vacuum defoaming; (6) spraying a polytetrafluoroethylene coating on the inner surface of the conductive disc mold, smearing an organic silicon release agent, and heating the conductive disc mold and preserving heat in a constant-temperature hot air oven; (7) vacuumizing the air pressure in a mold cavity through a vacuum pump; (8) pouring the inside of the mold cavity through the static mixing vacuum pouring equipment; (9) after the pouring is completed, carrying out heating curing on the conductive disc mold, and after furnace cooling, carrying out demolding; and (10) integrally milling and forming after demolding. According to the CT slip ring conductive disc forming method, the batch production can be realized, and the produced conductive disc is high in coaxiality.

Description

technical field [0001] The invention relates to the technical field of a CT slip ring, in particular to a method for forming a conductive disk of a CT slip ring. Background technique [0002] Disc slip ring is a kind of electric rotary connector, which can realize the unrestricted and free rotation transmission of signal and power. To make up for the disadvantage that the existing conductive slip ring must be installed in the center of the rotating shaft, it can be widely used in large security inspection machines, medical CT and other equipment. [0003] The size of the conductive disk of the CT slip ring is large, and the diameter can reach 1.5m. The current conductive disk manufacturing process on the market cannot well meet the preparation of the conductive disk with an outer diameter greater than 1 m, which affects the conduction of the CT slip ring to a certain extent. use of the disk. [0004] It is particularly necessary to independently develop a CT slip ring cond...

Problems solved by technology

[0003] However, the size of the conductive plate of the CT slip ring is relatively large, with a diameter of up to 1.5m. The current manufacturing process of the conductive plate on the market cannot well meet the preparation of the conductive plate with an outer diameter greater than 1m, which affects the conductivity of the CT slip ring to a certain extent.
