Abstract
The utility model discloses a nitrogen spring for an automobile die. The nitrogen spring comprises a cylinder base, a hollow cylinder body on the cylinder base, a plunger arranged in the hollow cylinder body and an air inflation assembly arranged on the cylinder base. The nitrogen spring is characterized in that the plunger is sequentially sleeved with a supporting ring, an inner plunger sleeve and a dust-proof seal cover from bottom to top, the bottom end of the plunger is fixedly sleeved with the supporting ring, the supporting ring is sleeved with the inner plunger sleeve, the dust-proof seal cover is arranged at the top of the hollow cylinder body, and meanwhile the top end of the plunger extends out of the hollow cylinder body. The nitrogen spring for the automobile die is simple in structure and convenient to use and install. Seal performance of the nitrogen spring for the automobile die is improved by arranging the dust-proof seal cover at the top of the hollow cylinder body.
Description
Technical field
the utility model relates to a kind of nitrogen spring, especially a kind of automobile die nitrogen spring.
Background technique
in recent years, fast development along with Domestic Automotive Industry, Ge great automobile factory has proposed more and more higher requirement to producing the important equipment mould of automobile, not only want to realize necessary function, and to reduce costs to greatest extent, thereby reduction product price, for enterprise development provides strong price guarantee.In producing the important equipment mould of automobile, using in a large number elastic element always, in recent years, Tool and Die Technology and mould manufacture level have a great development and improve, industrial products are increasing to the demand of mould, mould is towards precision, complicated, efficiently, long-life direction develops rapidly, and original conventional elastic means exists certain shortcoming, can not meet the needs of this situation, can not solve ideally the requirement of stamping process, often affect stamping part quality, make the mould structure design more complicated that becomes, affect the time that mould is changed on press machine, the die space that conventional elastic means is occupied is simultaneously too large, has increased the cost that mould is manufactured, for another example conventional elastic means is for requiring the techniques such as bending that initial force is larger, flange, also undesirable.Consequent result is, the quality of stamped part is unstable, and adjusting mould wastes time and energy.
Summary of the invention
the utility model object is: provide a kind of simple in structure, good airproof performance and automobile die nitrogen spring easy to install.
the technical solution of the utility model is: a kind of automobile die nitrogen spring, comprise cylinder seat, be located at the hollow cylinder body on described cylinder seat, be located at the plunger in described hollow cylinder body, and be located at the inflatable component on described cylinder seat, it is characterized in that, on described plunger, be set with successively the support ring arranging from bottom to top, plunger inner sleeve and dust seal cover, described support ring fixed cover is loaded on described plunger bottom, in described plunger, be sheathed on described support ring, described dust sealing is covered on described hollow cylinder body top, described plunger top extends to described hollow cylinder body outside simultaneously.
preferably, described inflatable component comprises the charging air inlet of being located at described cylinder seat side, for being communicated with the inner chamber of described hollow cylinder body and the inlet hole of described charging air inlet, and the plug screw of being located at described charging air inlet inlet.
preferably, described support surrounding place side is provided with circulatory motion seal ring.
the utility model has the advantages that:
1. of the present utility model simple in structure, easy to install, and improve the sealing of nitrogen spring for this automobile die by dust seal cover is set at hollow cylinder body top.
. the utility model further improves the sealing in nitrogen spring working procedure for this automobile die by circulatory motion seal ring being set at support surrounding place side.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the utility model structural representation;
wherein: 1 cylinder seat, 2 hollow cylinder bodies, 3 plungers, 4 support rings, 5 plunger inner sleeves, 6 dust seal covers, 7 charging air inlets, 8 inlet holes, 9 plug screws, 10 circulatory motion seal rings.
Embodiment
embodiment: shown in Fig. 1, a kind of automobile die nitrogen spring, comprise cylinder seat 1, be located at the hollow cylinder body 2 on cylinder seat 1, be located at the plunger 3 in hollow cylinder body 2, and be located at the inflatable component on cylinder seat 1, on plunger 3, be set with successively the support ring 4, plunger inner sleeve 5 and the dust seal cover 6 that arrange from bottom to top, support ring 4 fixed covers are loaded on plunger 3 bottoms, plunger inner sleeve 5 is located on support ring 4, dust seal cover 6 is located at hollow cylinder body 2 tops, and plunger 3 tops extend to hollow cylinder body 2 outsides simultaneously; 4 weeks sides of support ring are provided with circulatory motion seal ring 10; Inflatable component comprises the charging air inlet 7 of being located at cylinder seat 1 side, for being communicated with the inner chamber of hollow cylinder body 2 and the inlet hole 8 of charging air inlet 7, and the plug screw 9 of being located at charging air inlet 7 inlets.
the utility model has the advantage of, simple in structure, easy to install, and improve the sealing of nitrogen spring for this automobile die by dust seal cover 6 is set at hollow cylinder body 2 tops; In 4 weeks sides of support ring, circulatory motion seal ring 10 is set simultaneously and further improves the sealing in nitrogen spring working procedure for this automobile die.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications of doing according to the Spirit Essence of the utility model main technical schemes, within all should being encompassed in protection domain of the present utility model.
