Abstract
The utility model relates to an oil circuit control device of a three-way pipe fitting extrusion moulding machine, which comprises a one-way valve for injecting oil and an overflow valve, wherein the one-way valve and the overflow valve are disposed on an internal oil circuit outlet of an extrusion bar on one side of the extrusion moulding machine. The one-way valve and the overflow valve are simple and reliable in structure and can meet the largest work oil pressure of 2500 kilograms. The one-way valve can be connected between equipment and an external oil tank for a long time without having to opening and closing an oil injecting hole repeatedly and simultaneously prevents high-pressure oil flowing reversibly. The overflow valve can utilize the largest oil pressure when in manual adjusting and pressing so as to be adaptable to oil pressure tonnages with different requirements. When oil pressure in the equipment is larger than the largest oil pressure during bulging operation, the overflow valve opens automatically to drain and then reduce oil pressure, thereby protecting hydraulic systems of dies.

The utility model content
The applicant can not satisfy the shortcoming of the extruding production of large-scale heavy wall tee pipe fitting at above-mentioned existing tee pipe fitting extrusion molding oil way system, a kind of oil circuit control device of tee pipe fitting extrusion moulding machine simple and reliable for structure is provided, thereby can on existing equipment, carries out the extruding production of large-scale heavy wall tee pipe fitting.
The technical scheme that the utility model adopted is as follows:
A kind of oil circuit control device of tee pipe fitting extrusion moulding machine is included in tee pipe fitting extrusion moulding machine one side and pushes oiling check valve and the overflow valve that the outlet of excellent internal oil passages connects respectively; The valve seal of described oiling check valve is connected with oil-feed interface and oil out port, the oiling pipeline and the oiling chamber that communicate are arranged in the oiling check valve valve body, and form the oil circuit that communicates with oil-feed interface and oil out port respectively, described oiling is installed spool in the chamber, one end of spool and described oiling pipeline butt, the other end of spool is by spring and oil out port butt; The described overflow valve valve body one end oil-feed interface that is tightly connected, the other end and one is regulated nut and is connected, in the overflow valve valve body spill cavity is arranged, install spool in the described spill cavity, side at valve core rod has overfall on the overflow valve valve body, an end of spool and the inflow pipeline butt of described oil-feed interface, and the other end of spool is by a spring and a pushing block butt, the other end of pushing block is connected with an adjusting screw(rod), and adjusting screw(rod) is threaded with described adjusting nut.
The oil circuit control device of tee pipe fitting extrusion moulding machine, spool are piston-shaped.
Check valve and structure of relief valve that the utility model is provided with are simple and reliable, can satisfy maximum 2500 kilograms operating oil pressure.Check valve can be connected between equipment and the external fuel tank for a long time, does not need to carry out the unlatching closed procedure of oil filler point repeatedly, controls not reverse flow of high-voltage oil liquid simultaneously; Maximum oil pressure when overflow valve can adopt artificial adjustment compacting, thus the oil pressure pressure tonnage of different demands be applicable to; When the device interior oil pressure surpassed maximum oil pressure when bulging is worked, overflow valve was opened earial drainage automatically, reduced oil pressure, thus the hydraulic system of protection mould.
Description of drawings
Fig. 1 is for using tee pipe fitting extrusion moulding machine of the present utility model;
Fig. 2 is a check valve apparatus of the present utility model;
Fig. 3 is an overflow valve device of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, be connected with left side extruding rod 2 on the tee pipe fitting extrusion moulding machine side hydraulic cylinder 1, in the left side extruding rod 2 oil circuit 14 arranged, be equipped with the indication of observation oil pressure with 0～250Mpa special pressure table 3 in the oilhole outlet; Be connected with the right rod 7 that pushes on the side hydraulic cylinder 8 on right side, pushing in the rod 7 on the right side has oil circuit 9, and oil circuit 9 connects oiling check valve 6 and the overflow valve 10 of controlling the inner chamber oil pressure.Upside hydraulic cylinder 5 is connected with patrix 4, is provided with counterdie 12 in the bottom, is provided with push rod 11 in counterdie 12.Between patrix 4 and counterdie 12, place blank and squeeze out threeway 13.
The structure of check valve 6 of the present utility model as shown in Figure 2, be connected with oil-feed interface 21 and oil out port 28 in valve body 23 both sides, two interfaces all adopt screw thread to be connected with valve body 23, and be provided with sealing ring 22 and 26 connecting the end, valve body 23, oil-feed interface 21 is provided with the pipeline that is communicated with the axis of oil out port 28, the cavity 24 of a hollow is set and forms in valve body 23 and oil out port 28 junctions, spool 25 is set in cavity 24, spool 25 heads are taper, match at the opening of cavity 24 with valve body 23 central pipelines, spool 25 is terminal by spring 27 and oil out port 28 butts, spool 25 is similar to piston structure, but axial slip and assurance periphery and the sealing of cavity 24 walls.See Fig. 1, oil out port 28 is connected the arrival end that pushes excellent 7 internal oil passages 9 on the right side, and oil-feed interface 21 is connected to the special-purpose fuel tank of outside bulging.
During real work, see Fig. 2, Fig. 1, from 21 oilings of oil-feed interface, oiling pressure promotes spool 25 and retreats hydraulic pump from the fuel tank oil pumping, thereby fluid is from entering right side extruding rod 7 and pipe 13 from oil out port 28 smoothly.When filling with oil in the pipe 13 and carry out bulging work, the oil pressure in the pipe space is greater than oiling pressure, and inner fluid promotes spool 25 and seals oil-in, and hydraulic oil oppositely flows out from oil inlet end when avoiding work.
During real work, see Fig. 3, the position of pre-set adjusting screw(rod) 39 before work, adjusting screw(rod) 39 promotes pushing block 37, spring 34, makes coupling mechanism force be delivered to spool 32, thereby make spool 32 conical noses seal drain line 30, total this moment, this coupling mechanism force was exactly the maximum functional oil pressure.When the work of oil beginning bulging was filled with in the space of pipe 13, oil pressure rose this space in, when above above-mentioned total coupling mechanism force, fluid promotes spool 32 and retreats, when retreating to the position that no longer seals with valve body, fluid releases from overfall 33, thereby system oil pressure is descended.When the pressure shown in the Pressure gauge is excessive, but manual adjustment screw rod 39, so that draining pressure satisfies instructions for use.
More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, the utility model can be done any type of modification.
