At present, in the three-way pipe course of working, generally first forge into rectangle, and then, by the manufacturing process of saw or mill, it is manufactured to needed shape.Such manufacture, not only manufacturing efficiency is low, and the end properties produced is poor.Now, for manufacturing efficiency and the end properties that improves three-way pipe, need design three-way valve mold and threeway extrusion oil cylinder, and the cylinder bottom flange is the requisite structure of threeway extrusion oil cylinder.Therefore, it is vital designing a kind of cylinder bottom flange that can be used in the threeway extrusion oil cylinder.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cylinder bottom flange that can be used in the threeway extrusion oil cylinder is provided.
In order to achieve the above object, the utility model designs a kind of cylinder bottom flange of threeway extrusion oil cylinder, comprise the cylinder bottom flange body, it is characterized in that: the rear surface of cylinder bottom flange body is provided with groove one, the front surface of cylinder bottom flange body is provided with groove two, be provided with through hole between groove one and groove two, the middle part of cylinder bottom flange body is provided with annular groove one, be arranged with tooth-shape structure outside the front side of cylinder bottom flange body, the addendum surface of tooth-shape structure and the angle between Dedendum surface are 30 °, distance between the addendum surface center line of tooth-shape structure and Dedendum surface center line is 16 millimeters, the rear side of cylinder bottom flange body is arranged with three grades of steps outward, three grades of steps comprise step one, step two and step three, the front surface of step two is evenly equipped with 16 tapped holes, the outer surface of step three is provided with two annular grooves two.
The cross section of described annular groove one is trapezoidal.
The cross section of described annular groove two is rectangle.
The tooth-shape structure of described cylinder bottom flange body is arranged with the cylinder bottom nut outward.
Be embedded with piston rod in described groove one.
The outer cylinder bottom trim ring that is arranged with of the step two of described cylinder bottom flange body, between described cylinder bottom flange body and cylinder bottom trim ring, the employing tapped hole is connected.
Step three outer surfaces of described cylinder bottom flange body are arranged with cylinder body.
The utility model compared with the existing technology, changed the external and internal compositions of cylinder bottom flange, piston rod can be embedded in the cylinder bottom flange, also make cylinder bottom nut, cylinder bottom trim ring and cylinder body can be set in outside the cylinder bottom flange, thereby make the cylinder bottom flange can be used in the threeway extrusion oil cylinder, to improve manufacturing efficiency and the end properties of three-way pipe.
