Abstract
The utility model provides a kind of horn shape Compress Spring, comprises spring body, and described spring body is formed by stacking by metal wire rod is curling, the cross section of described metal wire rod is rounded, described spring body is horn-type structure, and its upper end is cylindrical part, and lower end is frustoconic shape part.The utility model makes Compress Spring shape into tubaeform, and Compress Spring and opponent's part area of contact are expanded, and to increase the stressed uniformity of loading, prevents that Compress Spring itself is because loading produces deformation, bending makes Compress Spring hydraulic performance decline.
Description
Technical field
The utility model relates to Compress Spring technical field, is specifically related to a kind of horn shape Compress Spring for oil pump.
background technique
Along with the fast development of Domestic Automotive Industry, auto manufacturing is increasing to the demand of mould, in punching press, plastic mould, is widely used elastic element, and particularly Compress Spring is as pusher, discharging, liftout, reset etc.In actual use, due to the existence of spring early failue problem, not only increase the workload of Mold repair, and affected normally carrying out of producing, the early failue of die springs is except the quality problems of spring itself, and spring also exists some problems with coordinating of opponent's part.
Especially the requirement of the spring in oil pump is higher, and this oil pump inner space is less, and connection mouth space, top is narrower, and pump body is longer, and spring fitting requirement for height is at 30mm, and the power while requiring to install has 100 N left and right.Due to the restriction of these sizes, if use the helical spring of typical circular steel wire in pump, spring can bending deflection in compression, causes the early failue of spring, if meet performance requirement with section wire, can greatly increase spring cost.
Model utility content
The utility model provides a kind of horn shape Compress Spring that can ensure quality of product, reduce product application risk.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of horn shape Compress Spring, comprises spring body, and described spring body is formed by stacking by metal wire rod is curling, and the cross section of described metal wire rod is rounded, and described spring body is horn-type structure, and its upper end is cylindrical part, and lower end is frustoconic shape part.
Further, the Length Ratio of described cylindrical part and frustoconic shape part is 2:1 to 3:1, comprises 2:1 and 3:1.
Further, the maximum diameter of described frustoconic shape part than for 1.5:1 to 2:1, comprises 1.5:1 and 2:1 with the diameter of cylindrical part.
Preferably, the total length of described spring body is 30mm to 40mm.
From above technological scheme, the utility model makes into tubaeform by Compress Spring shape, Compress Spring and opponent's part area of contact are expanded, to increase the stressed uniformity of loading, prevent that Compress Spring itself is because loading produces deformation, bending makes Compress Spring hydraulic performance decline; The change designing by shape, tubaeform Compress Spring is with respect to cylinder-shaped compression spring, and the stress of its setting height(from bottom) and working depth has reduced, and Security improves relatively; The pressure area of horn shape Compress Spring bottom increases, and can not be created in compression time, is subject to the impact of transverse force to cause spring in compression process, to produce distortion, extends the Compress Spring life-span and improves spring performance.
Brief description of the drawings
Fig. 1 is assembly structure schematic diagram of the present utility model, shows the upper and lower end of oil pump.
In figure: 1, spring body, 2, cylindrical part, 3, frustoconic shape part, 4, oil pump upper end, 5, oil pump lower end.
Embodiment
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present utility model is described in detail.
The utility model provides a kind of Compress Spring of horn-type structure, be mainly used in the long and narrow environment of installing space, especially the Compress Spring in oil pump, its spring length requirement is longer, being arranged to horn shape expands Compress Spring and opponent's part area of contact, to increase the stressed uniformity of loading, prevent that Compress Spring itself is because loading produces deformation, bending makes Compress Spring hydraulic performance decline.
As shown in Figure 1, Compress Spring of the present utility model comprises spring body, and described spring body is formed by stacking by metal wire rod is curling, the cross section of described metal wire rod is rounded, described spring body is horn-type structure, and its upper end is cylindrical part, and lower end is frustoconic shape part.For the raw-material selection of spring aspect, although section wire better performances, because cost is too high, without the market competitiveness, is therefore selected common round wire design spring.
The size of the upper end of Compress Spring of the present utility model and oil pump upper end connection mouth is suitable, adopt cylindrical part, while considering spring-compressed, external diameter becomes large, in the present embodiment, make Spielpassung between the external diameter of cylindrical part and oil pump upper-end inner diameter, when design makes spring-compressed like this, can not produce friction with oil pump internal diameter.For reaching the requirement of power, the total length of spring is designed to 30 to 40mm, and wherein the Length Ratio of cylindrical part and frustoconic shape part is 2:1 to 3:1, comprises 2:1 and 3:1.Consider the Security of spring in compression process, the maximum diameter of frustoconic shape part is 1.5:1 to 2:1 with the diameter of cylindrical part ratio, comprise 1.5:1 and 2:1, spring cylindrical part in compression process can not be absorbed in frustoconic shape partial interior and affect the normal use of Compress Spring like this.
The above mode of execution is only that preferred implementation of the present utility model is described; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
