Description
Technical Field
The utility model relates to a diaphragm is used to the cylinder, in particular to diaphragm is used to low friction proportion cylinder of electric current formula.
Background
The low-friction cylinder refers to a cylinder with small sliding resistance of a piston, and comprises a diaphragm type cylinder. The diaphragm type cylinder is an actuator which adopts a diaphragm capsule (cylinder diaphragm for short) as a seal, has no air leakage, no need of lubrication and small friction force, can provide power required by pushing, lifting, fastening, winding, rotating and other linear direction movements in various application occasions, and has a far-reaching market prospect.
The cylinder diaphragm is a cylinder with an opening at one end, the bottom surface of the cylinder is in contact with the piston head of the cylinder, and the cylinder diaphragm rolls over the surface of the piston along with the advance of the piston head, so that the frictional resistance between the piston and the cylinder is reduced. The traditional cylinder diaphragm is not specially provided with a research angle at the joint of the diaphragm opening and the diaphragm height, and is formed in a natural transition way only due to the manufacturing convenience. However, after a large number of experiments, the inventor finds that if the cylinder diaphragm has no angle or the angle is too small, the effective stressed area of the cylinder diaphragm is increased, so that the impact force is increased, and the service life of the cylinder is shortened; if the angle of the cylinder diaphragm is too large, the effective area of the cylinder diaphragm under stress is reduced, so that the required air source is larger, and the energy consumption cannot be reduced, and therefore, certain limitation on the angle is necessary.
In addition, the traditional cylinder diaphragm bottom R corner is generally provided with more than 2 layers of base cloth, which is mainly because the impact force is often very large when the cylinder is in operation, so in order to meet the service life of the cylinder, a circle of base cloth layer for reinforcing is usually required to be added at the bottom to compensate. A new rubber reinforcing layer 2 is additionally coated on the surface of the original base cloth layer 1 at the R' corner, so that a circle of the bottom of the diaphragm is locally thickened, and the performance sensitivity of the cylinder is often reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a diaphragm is used to low friction ratio cylinder of electric current formula has advantages such as frictional force is little, prevent static.
The diaphragm for the current type low-friction proportion cylinder comprises a diaphragm cover and a seal mounting ring, wherein the seal mounting ring is connected onto the diaphragm cover, the diaphragm cover comprises a base cloth layer, a middle bump layer and a rubber coating, the middle bump layer is anti-static particles and clamped between the base cloth layer and the rubber coating, anti-skidding bumps are shown on the inner surface of the diaphragm cover, the seal mounting ring comprises a base cloth layer and a rubber coating, an opening angle alpha is arranged at an opening of the diaphragm cover, and the degree of the opening angle alpha is 22-26 degrees.
Preferably, the opening angle α is 24 degrees.
Preferably, the thickness of the base fabric layer of the diaphragm cover is 0.25mm, the diameter of the antistatic particles is 0.02mm, and the thickness of the rubber coating is 0.3 mm.
Preferably, the thickness of the base cloth layer of the seal installation ring is 0.06mm, and the thickness of the rubber coating is 0.3 mm.
