Abstract
The utility model relates to the technical field of machines, in particular to a cylinder bottom pressing ring of a tee joint extrusion cylinder. The cylinder bottom pressing ring of the tee joint extrusion cylinder comprises a cylinder bottom pressing ring body, wherein a first stepped hole is formed inside the cylinder bottom pressing ring body, the first stepped hole is provided with two annular steps, the diameter of one annular step is 860 mm, and the diameter of the other annular step is 770 mm; steps are arranged on the periphery of the front side surface of the cylinder bottom pressing ring body; 16 second stepped holes are evenly distributed at the position, close to the first stepped hole, in the front side surface of the cylinder bottom pressing ring body; the second stepped holes penetrate through the front side surface of the cylinder bottom pressing ring body and the annular stepped surface of the first stepped hole. Compared with the prior art, the internal structure and external structure of the cylinder bottom pressing ring are changed so that a cylinder bottom flange can be sleeved with the cylinder bottom pressing ring, the cylinder bottom pressing ring can be embedded in a cylinder bottom of an oil cylinder, and the cylinder bottom pressing ring can be used on the tee joint extrusion cylinder so as to improve the production efficiency of a t-branch pipe and the performance of a finished product.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of cylinder bottom trim ring of threeway extrusion oil cylinder.
Background technique
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 trim ring is the requisite structure of threeway extrusion oil cylinder.Therefore, it is vital designing a kind of cylinder bottom trim ring 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 trim ring 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 trim ring of threeway extrusion oil cylinder, comprise cylinder bottom trim ring body, it is characterized in that: in cylinder bottom trim ring body, be provided with shoulder hole one, shoulder hole one is provided with two ring ladders, the diameter of two ring ladders is respectively 860 millimeters and 770 millimeters, the front side surface of cylinder bottom trim ring body is arranged with step outward, the front side surface of cylinder bottom trim ring body approaches shoulder hole one place and is evenly equipped with 16 shoulder holes two, and shoulder hole two runs through the ring ladder surface of front side surface and the shoulder hole one of cylinder bottom trim ring body.
The cross section of described step is annular, and interior circle radius is 970 millimeters, and exradius is 1000 millimeters.
The diameter of described shoulder hole two is respectively 860 millimeters and 770 millimeters.
At the bottom of described cylinder bottom trim ring body embeds oil cylinder, outside step is stuck at the bottom of oil cylinder.
Be embedded with the cylinder bottom flange in described shoulder hole one, between described cylinder bottom trim ring body and cylinder bottom flange, adopt shoulder hole two to be connected.
The utility model compared with the existing technology, changed the external and internal compositions of cylinder bottom trim ring, the cylinder bottom trim ring can be set in outside the cylinder bottom flange, the cylinder bottom trim ring also can be embedded at the bottom of oil cylinder, thereby make the cylinder bottom trim ring can be used in the threeway extrusion oil cylinder, to improve manufacturing efficiency and the end properties of three-way pipe.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Referring to Fig. 1 and Fig. 2,1 is cylinder bottom trim ring body; 2 is shoulder hole one; 3 is shoulder hole two; 4 is step.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1 and Fig. 2, the utility model has designed a kind of cylinder bottom trim ring of threeway extrusion oil cylinder, comprises cylinder bottom trim ring body.Be provided with shoulder hole 1 in cylinder bottom trim ring body 1, shoulder hole 1 is provided with two ring ladders, the diameter of two ring ladders is respectively 860 millimeters and 770 millimeters, the front side surface of cylinder bottom trim ring body 1 is arranged with step 4 outward, the front side surface of cylinder bottom trim ring body 1 approaches shoulder hole one 2 places and is evenly equipped with 16 shoulder holes 23, and shoulder hole 23 runs through the ring ladder surface of front side surface and the shoulder hole 1 of cylinder bottom trim ring body 1.
In the utility model, in order to coordinate with the internal structure of cylinder block better, the cross section of step 4 is annular, and interior circle radius is 970 millimeters, and exradius is 1000 millimeters.The diameter of shoulder hole 23 is respectively 860 millimeters and 770 millimeters.
The utility model is when work, at the bottom of cylinder bottom trim ring body 1 embeds oil cylinder, outside step 4 is stuck at the bottom of oil cylinder.Be embedded with the cylinder bottom flange in shoulder hole 1, between described cylinder bottom trim ring body 1 and cylinder bottom flange, adopt shoulder hole 23 to be connected.
The utility model has changed the external and internal compositions of cylinder bottom trim ring, the cylinder bottom trim ring can be set in outside the cylinder bottom flange, the cylinder bottom trim ring also can be embedded at the bottom of oil cylinder, thereby makes the cylinder bottom trim ring can be used in the threeway extrusion oil cylinder, to improve manufacturing efficiency and the end properties of three-way pipe.
