Description
The utility model relates to a kind of hydraulic power press, particularly a kind of portable hydraulic perforating press.
Existing hydraulic piercing press mainly is made up of hydraulic power station, frame, cylinder body, piston rod, sealing ring, drift, die, hold-down nut, back-moving spring, because back-moving spring is enclosed between the below and cylinder body cavity of resorption that is placed on piston on the piston rod, strengthened the cylinder body height, the relative piston effective travel that reduced, the perforating press volume is increased, weight increases, heaviness, uses and carries inconvenience.
The purpose of this utility model will provide a kind of portable hydraulic perforating press exactly, and not only volume is little for it.In light weight, consumable material is few, low cost of manufacture, and also use is carried light.
Task of the present utility model is following finishing, cylinder body with thread connection in locating the epimere macropore of cylindrical shoulder hole, C type frame upper right side is housed, the epimere macropore of the cylindrical shoulder hole of the cylindrical cavity of cylinder body and C type frame has constituted oil cylinder, in the hypomere of the cylindrical shoulder hole of oil cylinder and C type frame, piston rod is housed, the outside piston of the inwall of cylinder body and piston rod epimere seals with sealing ring, prevent leakage of oil, in the coaxial blind hole of piston rod is back-moving spring, one end of back-moving spring links to each other with the inner chamber of cylinder block upper surface, and the other end links to each other with piston rod.Drift is connected and fixed with the lower end of hold-down nut and piston rod, die is contained in C type frame lower right and locates in the cylindrical shoulder hole macropore, on the upper end wall of oil cylinder epicoele cylinder body, offer oilhole, can link to each other with the high-pressure oil pipe of hydraulic power station, hydraulic oil enters in the epicoele of oil cylinder, piston rod is moved downward, below die, have material-dropping hole feed beans to get rid of.
The utility model is that existing being placed on is enclosed within the oil cylinder cavity of resorption on the piston rod and back-moving spring in the piston below changes into and being placed in the coaxial blind hole of piston rod, because the change of back-moving spring shape, position, the volume of cylinder body and oil cylinder is reduced, weight saving, economical with materials, cost reduce, and portably use conveniently.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is the utility model concrete structure profile.
Fig. 2 is a profile under the utility model punching state.
Below in conjunction with Fig. 1, Fig. 2 describes in detail according to a specific embodiment of the present utility model, screw thread on the external cylindrical surface of the screw thread on the coaxial cylindrical shoulder hole epimere macropore inwall at C type frame 4 upper right side places and cylinder body 3 links to each other, the inner chamber of cylinder body 3 and C type frame 4 upper right side are located circular shoulder hole epimere macropore and have been constituted oil cylinder 9, locate in the sector hole piston rod 2 to be housed under the coaxial cylindrical shoulder hole in oil cylinder 9 and C type frame 4 upper right side, the inwall of piston on the piston rod 2 and cylinder body 3 seals with sealing ring 10, in the coaxial blind hole of piston rod 2 back-moving spring 1 is housed, one end of back-moving spring 1 is connected with cylinder body 3 upper end wall, and the other end is connected with piston rod 2.Offer oilhole 11 on cylinder body 3 roofs, when the high-pressure oil pipe of hydraulic power station and oilhole 11 connect good after, open reversal valve, under the effect of hydraulic oil and back-moving spring 1, piston rod 2 pumps, on the hypomere outside cylinder of piston rod 2, screw thread is arranged, the upper surface of drift 6 abuts against the lower surface of piston rod 2, and connected with hold-down nut 5, an another group shoulder hole coaxial with upper end cylinder shoulder hole is arranged at the bottom righthand side place of C type frame 4, the macropore of this group coaxial cylindrical shoulder hole epimere is equipped with die 7, the axis of die 7 is coaxial with piston rod 2, be material-dropping hole 8 below die 7, the course of work of portable hydraulic perforating press is as follows: with the workpiece 12 of certain width and thickness.Firm setting level between the drift 6 of normal diameter and coaxial die 7, the high-pressure oil pipe and the oilhole on the cylinder body 3 11 of hydraulic power station are connected, opening reversal valve makes hydraulic oil enter in the epicoele of oil cylinder 9 by oilhole 11, piston on the piston rod 2 in the hydraulic oil promotion oil cylinder 9 in the epicoele, the inwall of piston and cylinder body 3 is sealed with sealing ring 10, make it oil-proof, the piston rod 2 that moves downward is downward simultaneously with the drift 6 that its lower end firmly links to each other, drift 6 contacts with workpiece 12 earlier, under the extrusion shearing of drift 6, material generation plastic deformation on the workpiece 12 between drift 6 and die 7, shear, to expect that beans 13 wash out, material beans 13 drop out by material-dropping hole 8, the twisting reversal valve, piston rod 2 makes the hydraulic oil draining from oilhole 11 in oil cylinder 9 epicoeles under the elastic force effect of back-moving spring 1, above the piston of piston rod 2 shifted onto, promptly finished a course of work.
