Abstract

The utility model provides a prefill valve part for a hydraulic system of a bending machine, which aims to overcome the defect existing in the traditional mounting structure form. The prefill valve part for the bending machine comprises a prefill valve base in which a prefill valve is integrated and a section of oil pipe; a first oil port connected with a hydraulic cylinder pipeline is arranged on the prefill valve base; and one end of the oil pipe is connected with a second oil port pipeline of the prefill valve base through a first connector. The utility model has the advantages that firstly, the prefill valve part is directly connected with a hydraulic cylinder, and a middle pipeline for bearing high pressure is eliminated, so that the sealing reliability is greatly improved; secondly, the prefill valve part is in butt joint with an oil tank within a short distance, so that the integral structure is simple and attractive, and the cost is reduced; and thirdly, the prefill valve part can be firstly assembled and then mounted, so that the production efficiency is greatly improved.

Description

Bender liquid-filling valve parts
Technical field
The utility model relates to panel beating and uses the bender field, relates in particular to a kind of liquid filling valve for hydraulic system parts of bender.
Background technique
The topping up loop all is made up of liquid-filling valve (or Pilot operated check valve), topping up valve seat, control oil channel and coupled pipeline in the bender hydraulic system, it has two kinds of effects: 1) during the F.F. of bender knife rest, to the oil cylinder epicoele, make the oil cylinder epicoele be full of fluid from oil suction in the fuel tank; 2) during the bender return, make the fluid of oil cylinder epicoele flow back to fuel tank fast.Topping up loop operating mode characteristics are big flows, also need bear high pressure simultaneously, so the mounting structure form in topping up loop is very important, are related to attractive in appearance, the efficiency of assembling and the sealing of hydraulic system pipeline.
Bender hydraulic system topping up loop mainly is installed on the oil cylinder end face or above the fuel tank, by pipeline liquid-filling valve, oil cylinder and fuel tank three is coupled together then both at home and abroad at present.The mounting type that facts have proved above traditional topping up loop apparatus has following shortcoming.1. pipeline is too complicated, not attractive in appearance; 2. efficiency of assembling is low excessively; 3. seal for pipe joints is poor.
Summary of the invention
The utility model provides a kind of bender liquid filling valve for hydraulic system parts at above problem, to eliminate the shortcoming in traditional mounting structure form.
For achieving the above object, the utility model has been taked following technological scheme:
Bender liquid-filling valve parts, topping up valve seat and the one section oil pipe of liquid-filling valve that comprised an internal integration; Described topping up valve seat is provided with and is used for first hydraulic fluid port that is connected with the oil hydraulic cylinder pipeline; One end of described oil pipe is connected with the second hydraulic fluid port pipeline of topping up valve seat by first joint.
The other end of described oil pipe is provided with and is used for second joint that is connected with the fuel tank pipeline.
Above-described first joint and second joint can be that the flange-type pipe connects, and oil pipe is enclosed within the position that the flange-type pipe connects, and the leakproof of reinforced steel wire larynx hoop is housed.
On the topping up valve seat, can be provided with control cover plate, be used to connect the hydraulic control oil circuit of liquid-filling valve.
The topping up valve seat is fixed on the side of oil hydraulic cylinder by screw, and first hydraulic fluid port and oil hydraulic cylinder epicoele are connected, and oil pipe is connected to fuel tank, has realized that so just the hydraulic pipe line between " fuel tank-topping up valve seat-oil hydraulic cylinder " three connects.Be incorporated into liquid-filling valve in the topping up valve seat and be directly installed on the oil hydraulic cylinder, can simplify the mounting structure in topping up loop on the one hand, shorten oil circuit and connect, on the other hand, the topping up valve seat is made by the slug material, has higher bearing capacity.And the oil pipe of software can be convenient to the topping up valve seat and be connected with pipeline between the fuel tank.
Liquid-filling valve parts of the present utility model, can finish the assembling of this parts earlier after, be installed to again on the complete machine, avoid needing in the past to intercept the way of tubing length according to complete machine, improved manufacturing efficiency greatly.
The beneficial effects of the utility model are: (1) liquid-filling valve parts directly are connected with oil hydraulic cylinder, have cancelled the intermediate conduit of bearing high pressure, have improved the reliability of sealing greatly; (2) the liquid-filling valve parts are realized short-range the butt joint with fuel tank, and overall structure is simple, attractive in appearance and reduced cost; (3) the liquid-filling valve parts can be assembled earlier, and install the back, has improved manufacturing efficiency greatly.

Embodiment
Below in conjunction with drawings and Examples the utility model content is described further.
As shown in Figure 1, fuel tank 1, oil hydraulic cylinder 2 carry out the pipeline connection by liquid-filling valve parts 3.
The structure of liquid-filling valve parts 3, as shown in Figure 2.Liquid-filling valve parts 3 by topping up valve seat 4, the first flange-type pipe connect 5, oil pipe 6 and the second flange-type pipe connect 7 and assemble successively.
As shown in Figure 3, integrated liquid-filling valve in the topping up valve seat 4, topping up valve seat 4 outsides are provided with first hydraulic fluid port 8 and second hydraulic fluid port 9.First hydraulic fluid port 8 is used to be communicated to the epicoele of oil hydraulic cylinder 2; Second hydraulic fluid port 9 is used to be communicated with oil pipe 6, and its outside is equipped with the first flange-type pipe and connects 5.On topping up valve seat 4, control cover plate 10 also is installed, control cover plate 10 is provided with the oily interface 11 of control, and this interface is used to connect the hydraulic control oil circuit of liquid-filling valve.
Oil pipe 6 is enclosed within the first flange-type pipe and connects the 5 and second flange-type pipe and connect between 7.For preventing the jointing leakage of oil, oil pipe 6 is enclosed within the position that the flange-type pipe connects, and reinforced steel wire larynx hoop 12 is housed.
More than after each part can be assembled into the liquid-filling valve parts earlier, be installed on the complete machine again.During installation, first hydraulic fluid port 8 is connected to the epicoele of oil hydraulic cylinder 2; The second flange-type pipe connects 7 and is connected on the fuel tank 1.
What this specification was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under working principle of the present utility model and thinking all are considered as protection domain of the present utility model.
