Abstract
The utility model relates to a forming die device of an oil return tube socket part in a pressure regulating valve component of an automobile engine, in particular to a built-in check valve device of an expanding type stamping die. The check valve device is arranged in a main body with a punch at the upper part and a valve body at the lower part; and a slender long through hole is formed on the main body. The check valve device is characterized in that a spring, a valve core, a valve seat and a plug screw are sequentially mounted in the valve body from the top down; the valve core and the valve seat are sealed on a conical surface; and a sealing copper strip is arranged between the valve seat and the inner plane of the valve body. The utility model mainly solves the technical problems that the prior ordinary hydraulic pressure expanding type die has a big structure, the sealing piece generally adopts a sealing ring or an O-shaped ring, the service life is short, the structure of the hydraulic pressure system is complex, and the prior expanding type die is difficult to suit automatic production; and furthermore, the check valve device has the advantages of small volume, high flexibility, reliable operation, long service life of the die and greatly reduced manufacture cost, and is applicable to automatic production.
Description
Technical field
The utility model relates to the mould device of oil return base part in a kind of automobile engine valve module of voltage regulation, particularly a kind of punching press built-in check valve apparatus of pattern tool that expands.
Background technology
Oil return base part in the automobile engine valve module of voltage regulation is assembled by punching press drawing part oil return base and car product oil return pipe, in order to reduce cost, the oil return base is designed to the punching press drawing part of one, the head moulding as shown in Figure 1, and dimensional requirement and surface quality have strict demand.In order to improve the head shaping strength, satisfy the part quality requirement, need to adopt hydraulic expanding type technology to realize.Common hydraulic expanding type mould structure is bigger, and seal generally adopts sealing ring or O type circle, and the life-span is shorter, the hydraulic system structure complexity, and be difficult to adapt to automated production.
The utility model content
The purpose of this utility model is to provide a kind of punching press built-in check valve apparatus of pattern tool that expands, it is bigger mainly to solve existing common hydraulic expanding type mould structure, and seal generally adopts sealing ring or O type circle, and the life-span is shorter, the hydraulic system structure complexity, and be difficult to adapt to the technical problem of automated production, its volume is little, and flexibility is strong, reliable operation, die life is long, greatly reduces manufacturing cost, and can adapt to automated production.
For addressing the above problem, the utility model is achieved in that
A kind of punching press built-in check valve apparatus of pattern tool that expands, it is arranged on top is that punch, bottom are in the main body of valve body, this main body is provided with one and connects elongated hole up and down; It is characterized in that: spring, spool, valve seat and plug screw are installed in the described valve body from top to bottom successively; Spool and valve seat are with conical surface seal, and a sealing copper sheet is set between valve seat and the valve body inner plane.
The described punching press built-in check valve apparatus of pattern tool that expands, it is characterized in that: described valve seat small end inwardly.
The described punching press built-in check valve apparatus of pattern tool that expands is characterized in that: described plug screw lower surface does not exceed the main body baseplane and installs.
By technique scheme, the beneficial effects of the utility model are:
The beneficial effects of the utility model are, volume is little, and flexibility is strong, reliable operation, and die life is long, greatly reduces manufacturing cost, and can adapt to automated production.
Description of drawings
Fig. 1 is the part figure after the oil return base formed product;
Fig. 2 is a cross-sectional view of the present utility model;
Fig. 3 is the A portion partial enlarged drawing of Fig. 2.
Among the figure, 1 main body, 2 springs, 3 spools, 4 sealing copper sheets, 5 valve seats, 6 plug screws.
The specific embodiment
See also Fig. 1,2, the utility model provides a kind of punching press built-in check valve apparatus of pattern tool that expands.As shown in the figure: it is arranged on top is that punch, bottom are in the main body 1 of valve body, and this main body 1 is provided with one and connects elongated hole up and down; Upper end punch profile and Fig. 1 product endoporus are fitted and are formed sealing, and the center elongated hole is the passage of the product cavity of medium inflow for liquid.Spring 2, spool 3, valve seat 5 and plug screw 6 are installed in the described valve body from top to bottom successively; Spool 3 is with conical surface seal with valve seat 5, and a sealing copper sheet 4 is set between valve seat 5 and the valve body inner plane.
Built-in check valve of the present utility model, spool and valve seat are with conical surface seal, place a sealing copper sheet in the middle of valve seat and the punch inner plane, the sealing surface of valve seat is processed into hangnail, and the fastening back of plug screw forms hard sealing, and plug screw must not exceed the punch baseplane, assemble the available thimble in back and promote spool by oilhole less than the lower end oilhole, spool should have certain acting force of the spring, and certain movement length is arranged, and can reset fully after thimble unclamps.
During work, it is fixing that punch assemblies is pressed into fixed head, and liquid medium enters valve seat 5 with the operating pressure of oil pump by mold runner, struts spool 3, flow into product cavity, patrix is along with forcing press is descending, and product is pressed into punch formation and seals, and the inner chamber medium presses down spool 3 and valve seat 5 conical surfaces applying formation sealing along with pressure increases refluence formation pressure, along with forcing press continues descending, the product cavity liquid medium can not be compressed, and forms high pressure, can reach the purpose of hydraulic expanding type.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
