Abstract
The utility model belongs to the technical field of springs, in particular to an outer oblique tail-closing spring, and solves the problems such as easy grinding on workpieces and poor stability of the existing spring. The outer oblique tail-closing spring comprises a spring body formed by winding a spring wire rod; the outer oblique tail-closing spring is characterized in that at least one end of the spring body is bent towards the outside from the inside of the spring body to form an outer oblique tail-closing part, and the outer oblique tail-closing part and the end face of the spring body are positioned at the same plane and are vertical to the central line of the spring body. Compared with the prior art, the outer oblique tail-closing spring has the advantages of being simple and reasonable in structure, high in stability, strong in stability, high in strength and uniform in stress, in the use process the spring is not easily rubbed with the workpieces inside or outside the spring and the damage of the workpieces is not easily caused.
Description
Technical field
The utility model belongs to the spring technical field, especially relates to a kind of outer inclined ending spring.
Background technique
The purposes of spring is very extensive, is almost the indispensable element of common mechanical, when it is subjected to External Force Acting, namely produces resiliently deformable, thereby has stored strain energy and disengaged at random, the kind of spring, structural type, functional diversities.In the kind of spring, Compress Spring is a kind of helical spring that bears pressure, for a kind of spring that is the most extensively used in all spring kinds, between the circle of Compress Spring and circle, certain gap is arranged, spring contraction distortion when being subject to external load, store the sex change energy, the distortion of unloading rear spring disappears and reinstatement, and energy of deformation is converted into to mechanical work or kinetic energy.But existing spring exists many problems, such as the spring end face structure, tends to the sharp edge burr that produces due to the end face section etc. and causes the workpiece of installing in spring scratch or cause workpiece to damage with the mutual friction of workpiece phase.In addition, existing spring also exists: poor stability when spring uses, and smoothness is poor, and intensity is low, the problems such as discontinuity.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of spring with ends buckled outward [application number: 200920300796.7], it is characterized in that: the end portion of spring body is connected with the outer warping end head that is folded to spring body cylindrical outer diameter direction from spring body cylindrical inner diameter, and another end portion of spring body is connected with the outer warping end head that is folded to spring body cylindrical outer diameter direction equally.The be folded to distance of outer warping end head from spring body cylindrical inner diameter to the external diameter direction is 1/3～1/2 of spring body wire rod wire diameter.
Such scheme has solved the existing spring end face ending place problem that is plugged in the workpiece in spring easy to wear to a certain extent, but this scheme still exists: complex structure, the friction of workpiece that spring end face ending place is easy and spring is outer, poor stability when spring uses, smoothness is poor, intensity is low, the problem of discontinuity.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of simple and reasonable, and stationarity is high, not the outer inclined ending spring of workpiece easy to wear.
For achieving the above object, the utility model has adopted following technical proposal: this outer inclined ending spring, comprise the spring body of reeling and forming by a spring wire, it is characterized in that, the end of at least one end of described spring body bends the rear outer inclined ending section that forms laterally by spring body inboard, and the end face of described outer inclined ending section and spring body is in the same plane and all perpendicular to the center line of described spring body.Can avoid the end of spring body and be plugged in the intrinsic friction of workpiece of spring, while having guaranteed simultaneously the use of spring body, stability is high, and stationarity is strong.
In above-mentioned outer inclined ending spring, described spring body is volute spring, and described outer inclined ending section is located at the small end of spring body.
In above-mentioned outer inclined ending spring, the end of described outer inclined ending section to the substantially horizontal distance of the center line of spring body less than the end of the large end of the spring body substantially horizontal distance to the center line of spring body.Can avoid the workpiece phase mutual friction in outer inclined ending section and the spring body outside.
In above-mentioned outer inclined ending spring, the cross section of described spring wire is rounded, and the wire diameter of described spring body is 1.5mm-2mm.
In above-mentioned outer inclined ending spring, the internal diameter of the small end of described spring body is 7mm, and the internal diameter of the large end of described spring body is 18mm.
Compared with prior art, the advantage of this outer inclined ending spring is: simple and reasonable, in the spring using process, be difficult for friction of workpiece inboard with spring and the outside, and be difficult for causing the damage of workpiece, stability is high, and stationarity is strong, and intensity is high, and is stressed even.
The accompanying drawing explanation
The structural representation that Fig. 1 provides for the utility model.
The structural representation at another visual angle that Fig. 2 provides for the utility model.
In figure, spring body 1, outer inclined ending section 2.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1-2, this outer inclined ending spring, comprise the spring body 1 of reeling and forming by a spring wire, the end of at least one end of spring body 1 bends the rear outer inclined ending section 2 that forms laterally by spring body 1 inboard, outer inclined ending section 2 is in the same plane and all perpendicular to the center line of described spring body 1 with the end face of spring body 1, can avoid the end and the friction of workpiece that is plugged in spring body 1 of spring body 1, while having guaranteed simultaneously 1 use of spring body, stability is high, and stationarity is strong.
As a kind of technological scheme of comparatively optimizing, in the present embodiment, spring body 1 is volute spring, and outer inclined ending section 2 is located at the small end of spring body 1.The end of outer inclined ending section 2 less than the end of the spring body 1 large end substantially horizontal distance to the center line of spring body 1, can be avoided the workpiece phase mutual friction in outer inclined ending section 2 and spring body 1 outside to the substantially horizontal distance of the center line of spring body 1.The cross section of spring wire is rounded, and the wire diameter of described spring body 1 is 1.5mm-2mm.The internal diameter of the small end of spring body 1 is 7mm, and the internal diameter of the large end of described spring body 1 is 18mm.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as spring body 1, outer inclined ending section 2, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
