Abstract
The utility model discloses a top type compression spring, including oil pump upper end, oil pump lower extreme, path spring, big footpath spring, spring safety cover and pivot, its characterized in that: big footpath spring links to each other with the path spring, big footpath spring top is equipped with the oil pump upper end, path spring lower extreme is connected with the oil pump lower extreme, be equipped with the spring safety cover between oil pump upper end and the oil pump lower extreme, be equipped with the pivot on the spring safety cover, the spring safety cover is located compression spring's the outside, the utility model discloses simple structure, convenient operation changes traditional circular spring into the top type for the atress of spring mainly concentrates mid portion on, and setting up of spring safety cover makes inside compression spring obtain the protection, and bears partly pressure, makes the life greatly increased of spring.
Description
Technical field
The utility model relates to Compress Spring technical field, is specially a kind of top-type Compress Spring.
Background technique
Along with the fast development of Domestic Automotive Industry, the demand of auto manufacturing to mould is increasing, in punching press, plastic mould, widely use elastic element, 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 have impact on normally carrying out of production, the early failue of die springs is except the quality problems of spring itself, and spring also also exists some problems with coordinating of opponent's part.
Especially the spring in oil pump requires higher, this oil pump inner space is less, and connection mouth space, top is narrower, and pump body is longer, spring fitting requirement for height is at 30mm, require that power when installing has about 100N, due to the restriction of these sizes, if use the helical spring of typical circular steel wire in pump, spring is meeting bending deflection in compression, cause the early failue of spring, if use section wire to meet performance requirement, then can greatly increase spring cost.
Model utility content
The purpose of this utility model is to provide a kind of top-type Compress Spring, to solve the problem proposed in above-mentioned background technology.
For achieving the above object; the utility model provides following technological scheme: a kind of top-type Compress Spring; comprise oil pump upper end, oil pump lower end, little diameter spring, large diameter spring, spring protection cover and rotating shaft; it is characterized in that: described large diameter spring is connected with little diameter spring; oil pump upper end is provided with above described large diameter spring; described path lower spring end is connected with oil pump lower end; spring protection cover is provided with between described oil pump upper end and oil pump lower end; described spring protection cover is provided with rotating shaft, and described spring protection cover is positioned at the outside of Compress Spring.
Preferably, the total height of described large diameter spring and little diameter spring is 30mm.
Preferably, the diameter of described large diameter spring is two times of little diameter spring.
Preferably, the cross section of described spring protection cover is rhombus.
Compared with prior art; the beneficial effects of the utility model are: a kind of top-type Compress Spring; structure is simple; easy to operate; change traditional coil component spring into top-type, make the stressed of spring mainly concentrate on intermediate portion, spring protection cover be arranged so that inner Compress Spring is protected; and bear a part of pressure, the working life of spring is increased greatly.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, oil pump upper end, 2, oil pump lower end, 3, little diameter spring, 4, large diameter spring, 5, spring protection cover, 6, rotating shaft.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1; the utility model provides a kind of technological scheme: a kind of top-type Compress Spring; comprise oil pump upper end 1, oil pump lower end 2, little diameter spring 3, large diameter spring 4, spring protection cover 5 and rotating shaft 6; it is characterized in that: described large diameter spring 4 is connected with little diameter spring 3; oil pump upper end 1 is provided with above described large diameter spring 4; described little diameter spring 3 lower end is connected with oil pump lower end 2; spring protection cover 5 is provided with between described oil pump upper end 1 and oil pump lower end 2; described spring protection cover 5 is provided with rotating shaft 6, and described spring protection cover 5 is positioned at the outside of Compress Spring.
Described large diameter spring 4 is 30mm with the total height of little diameter spring 3, and the diameter of described large diameter spring 4 is two times of little diameter spring 3, and the cross section of described spring protection cover 5 is rhombus.
Concrete usage mode: the utility model in use; by the top-type Compress Spring that large diameter spring 4 and little diameter spring 3 are combined into; the stressed of spring is made mainly to concentrate on intermediate portion; spring protection cover 5 be arranged so that inner Compress Spring is protected; and bear a part of pressure, the working life of spring is increased greatly.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
