Description
Technical Field
The invention belongs to the technical field of precision optical machine assembly and adjustment, and particularly relates to a silicon rubber cutting device and a silicon rubber cutting method.
Background
The silicon rubber has certain elasticity after being cured, and is often used for bonding optical elements in an optical-mechanical system, so that the influence of stress on the optical elements can be reduced. Because the space of an optical-mechanical system is compact, the thickness of a silicon rubber bonding adhesive layer is small (generally less than 1mm), and how to remove parts bonded by silicon rubber becomes a technical problem, and the existing removal mode mainly comprises two modes of physical cutting and chemical soaking.
Chemical soaking generally directly foams silicon rubber to be removed in solvents capable of dissolving the silicon rubber, such as ether, gasoline and the like, the method is simple to operate, and the solvents can reach all narrow spaces, but have two disadvantages: firstly, the solvent needs to be soaked for a long time and fully reacts with the silicon rubber, and the larger the area of the rubber layer is, the longer the removal time is; and secondly, solvents such as ether and gasoline can cause the falling off of the film layers of the optical parts and the paint layers of the mechanical parts, thereby limiting the application range of the method.
In general, in physical cutting, a cutter or a wire saw is selected to cut the adhesive layer according to conditions such as the depth and the operable space of the adhesive layer, the cutter can only be used in scenes with shallow adhesive layers and large operating space, and the wire saw can cut a bonding surface with narrow and complex operating space and deep adhesive layer. The wire saw cutting principle is that silicon rubber is cut by carborundum on a steel wire in a reciprocating motion, however, during cutting, the temperature of the steel wire is increased by heat generated by friction, the mechanical property of the steel wire is reduced, and the steel wire is easy to break. In the cutting process, the cut silicon rubber still tightly wraps the steel wire due to elasticity, and the steel wire cannot be cooled by continuously watering like cutting metal. The surface of the steel wire is also adhered by silicon rubber scraps, so that the cutting effect of the carborundum is weakened, and the heat generated during cutting is further increased. When a common wire saw is used for cutting silicon rubber with the Shore A hardness of more than 50 by using a steel wire with the diameter of 0.35mm, the steel wire can be broken when the rubber layer with the depth of 2-3mm is cut on average, the time for replacing the steel wire accounts for more than 50% of the total cutting time, and the cutting efficiency is seriously influenced.
In view of the above, there is a need for a new silicone rubber cutting device and cutting method.

3) disassembling the side cover and the ratchet wheel on the frame, winding the steel wire passing through the slit around the two guide wheels and the tension wheel of the frame, winding and fixing the residual steel wire on the winding post, and reinstalling the side cover and the ratchet wheel;
4) adjusting the tensioning wheel by using a tensioning nut to tension the steel wire;
5) installing a detachable brush head;
6) pulling the cutting device to cut the silicon rubber, rotating the ratchet wheel to convey the steel wire when the frame moves forwards, and keeping the ratchet wheel still when the frame moves backwards, wherein the steel wire cuts the silicon rubber;
7) when the steel wire wound on the winding post in the forward direction is completely and reversely wound to the other side, the claw is pressed down by hand, the ratchet wheel is loosened, meanwhile, the steel wire is contacted on the silicon rubber layer and pulled backwards, the steel wire can be wound in the forward direction again by means of the friction force between the silicon rubber and the steel wire, the initial position is recovered, and the cutting is started again.
