Wherein, in use, because oil pressure is too high, all may there is leakage of oil situation in all welding positions of its high-voltage tube part to hydraulic oil press, especially, when high strength, high running rate compacting massive article, has a strong impact on the normal operation of production.
Utility model content
The purpose of this utility model is to provide a kind of high-pressure drive for hydraulic press hydraulic system, has solved existing high-voltage drive pipe in use, the problem of the welding position leakage of oil occurring because oil pressure is too high.
The technical scheme that the utility model adopts is: for the high-pressure drive of hydraulic press hydraulic system, comprise master cylinder and side cylinder, one side of side cylinder is connected with one end of three-way pipe, the other two ends of three-way pipe are connected with respectively tube connector and petroleum pipeline, tube connector is connected to master cylinder, and tube connector is one-time formed pipeline.
Feature of the present utility model is also,
Tube connector comprises connected successively traversing section, segmental arc and vertical section, and one end of traversing section is connected to master cylinder, and vertically one end of section is connected to three-way pipe.
The radius of curvature of segmental arc is not less than 50cm.
The beneficial effects of the utility model are: reduced the hydraulic oil impulsive force for pipeline in service, the vibration in use of hydraulic press high-voltage tube reduces greatly, has reduced equipment failure rate, has saved maintenance cost, has improved operation rate.

In figure, 1. master cylinder, 2. tube connector, 3. side cylinder, 4. three-way pipe, 5. petroleum pipeline, 6. transverse pipe, 7. VERTICAL TUBE, 8. corner tube, 21. traversing sections, 22. segmental arcs, 23. vertical sections.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing, the utility model is elaborated.
The utility model provides a kind of high-pressure drive for hydraulic press hydraulic system, as shown in Figure 1, comprise master cylinder 1 and side cylinder 3, one side of side cylinder 3 is connected with one end of three-way pipe 4, the other two ends of three-way pipe 4 are connected with respectively tube connector 2 and petroleum pipeline 5, tube connector 2 is connected to master cylinder 1, and tube connector 2 is one-time formed pipeline.
As shown in Figure 2, tube connector 2 comprises connected successively traversing section 21, segmental arc 22 and vertical section 23, and one end of traversing section 21 is connected to master cylinder 1, and vertically one end of section 23 is connected to three-way pipe 4.
The radius of curvature of segmental arc 22 is not less than 50cm.
Be illustrated in figure 3 the structure of the high-pressure drive of prior art, Comparatively speaking, the utility model adopts one-time formed tube connector 2, the transverse pipe 6, VERTICAL TUBE 7 and the corner tube 8 that have replaced prior art, and from function, the traversing section 21 of tube connector 2 is corresponding to transverse pipe 6, and segmental arc 22 is corresponding to corner tube 8, and vertically section 23 is corresponding to VERTICAL TUBE 7.
During high-pressure drive work of the present utility model, hydraulic oil enters from the lower end of petroleum pipeline 5, first through three-way pipe 4, flows to side cylinder 3, side cylinder 3 is started working, and meanwhile, hydraulic oil enters tube connector 2 by petroleum pipeline 5, by tube connector 2, enter into master cylinder 1 again, master cylinder 1 is started working.
In prior art, due to production space and production-scale needs, after needing first to determine position relationship between transverse pipe 6, VERTICAL TUBE 7 and corner tube 8, adopt again the mode of welding to connect, and because corner tube 8 is folding type structure, hydraulic oil through wherein time, is easily stopped and pipeline is produced to very large impulsive force, cause pipeline welding point to be subject to great concentrated stress, hydraulic oil of a specified duration will be from the outside seepage of weld seam.
And tube connector 2 of the present utility model is one-time formed pipeline, need not, through welding, therefore there is no weld seam; Also the radius of curvature due to segmental arc 22 is not less than 50cm, when hydraulic oil therefrom flows through, can not make because of the turning of right angle or other folding type hydraulic oil produce larger impulsive force.That is to say, the utility model connects by the circular arc of removing weld seam and being segmental arc 22 by the turning formula Innovation of Connection of corner tube 8, has reduced the risk of the hydraulic oil seepage device from two aspects.
By the way, the utility model has solved existing high-voltage drive pipe in use, the problem of the welding position leakage of oil occurring because oil pressure is too high, reduced the hydraulic oil impulsive force for pipeline in service, the vibration in use of hydraulic press high-voltage tube reduces greatly, reduce equipment failure rate, saved maintenance cost, improved operation rate.
