Abstract
The utility model relates to a ring-shaped clamping sleeve for a hydraulic pipe joint, which comprises a pressing surface, a high flat surface, a low flat surface, a clamping surface and clamping blades. An inner surface of the clamping sleeve is provided with the clamping blades. The high flat surface and the low flat surface are in transition connection through an arc surface. An inclination angle theta 2 of the pressing surface and the inner surface of the clamping sleeve is in the range of 55 to 60 degrees. The inclination angle theta 1 of the clamping surface and the inner surface of the clamping sleeve is in the range of 18 to 20 degrees. Two clamping blades are arranged. The height of the left clamping blade is lower than the height of the right clamping blade. The top corner of each clamping blade is of a round shape and has a radius of 0.01 to 0.02mm. The high flat surface is 2 to 3mm higher than the low flat surface. The inner surface of the clamping sleeve is provided with the clamping blades, and the clamping sleeve cannot rebound when being pressed, so that the oil leakage phenomenon cannot occur. Moreover, an outer surface of the clamping sleeve is inclined at a certain angle, so that the clamping sleeve is more convenient and more labor-saving to install and has a wide market space.
Description
Technical field
The utility model relates to a kind of annular cutting ferrule, mainly is the good hydraulic fitting cutting ferrule of a kind of sealing, belongs to the hydraulic machinery field.
Background technique
Along with deepening constantly of reform, shipping industry and shipping business develop rapidly, the utilization of hydraulic machinery also more and more widely, especially more and more to the use of the hydraulic equipment of low-speed big, therefore also hydraulic pipe line is had higher requirement, some cutting ferrule internal surfaces of usefulness all are flat at present, and simple structure, therefore will cause leakage of oil for the high slightly hydraulic pipe line of pressure, influence the normal use of hydraulic equipment, the cutting ferrule of being badly in need of a kind of more reliable performance at present replaces.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic fitting annular cutting ferrule.
Problem to be solved in the utility model is the deficiency of existing hydraulic tube annular cutting ferrule easy oil leakage.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
The utility model hydraulic fitting annular cutting ferrule, comprise seal face, high plane, low degree, chucking face and card sword, the cutting ferrule internal surface is provided with the card sword, high plane is connected by the arc surface transition with low degree, the tiltangle 2 of seal face and cutting ferrule internal surface is the 55-60 degree, and the tiltangle 1 of chucking face and cutting ferrule internal surface is the 18-20 degree.
The card sword is provided with 2, and the height of left side card sword is lower than the height of right side card sword, and the drift angle of card sword is rounded, and radius is 0.01-0.02mm; High plane is higher than low degree 2-3mm.
The utility model has the advantages that: the cutting ferrule internal surface is provided with the card sword, can not rebound after compressing, so can not cause oil leakage phenomenon, and outer surface is certain skewed, installs more convenient laborsavingly, should have the market space widely.
Description of drawings
Fig. 1 be the utility model hydraulic fitting annular cutting ferrule partly cut open schematic representation;
Fig. 2 is the left view of the utility model hydraulic fitting annular cutting ferrule;
Fig. 3 is the card sword enlarged view of the utility model hydraulic fitting annular cutting ferrule;
Among the figure: 1, seal face 2, high plane 3, low degree 4, chucking face 5, card sword.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, the utility model hydraulic fitting annular cutting ferrule, comprise seal face 1, high plane 2, low degree 3, chucking face 4 and card sword 5, the cutting ferrule internal surface is provided with card sword 5, high plane 2 is connected by the arc surface transition with low degree 3, seal face 1 is 60 degree with the tiltangle 2 of cutting ferrule internal surface, and chucking face 4 is 18 degree with the tiltangle 1 of cutting ferrule internal surface.
The utility model hydraulic fitting annular cutting ferrule outer surface can be programmed by numerically controlled lathe, from left to right time processing forms, internal surface can go out 2 card swords 5 with special-purpose lathe tool car again by the two ends of numerically controlled lathe elder generation car to card sword 5, and the utility model has just machined like this.
