Abstract
The utility model discloses an end beveled spring. A tail end part (3) of a spring body (1) is provided with a beveled end surface (2) which forms a bevel angle with an end surface (4) of the spring body (1); and the beveled end surface (2) extends from the end surface (4) to the tail end with the direction inclining towards the spring body (1). The beveled end surface (2) is the bevel section of the whole steel wire at the tail end part (3) inclining towards the spring body (1). The end beveled spring changes the traditional mode of cutting section, and avoids the damage to the assembled and used components, which is caused by the scratch of sharp-edge burr, outward convexness and inward concavity generated by section cutting of the end with the assembled and used components, especially with the plastic parts and rubber parts.
Description
Technical field
The utility model relates to a kind of spring, especially a kind ofly carries out the spring of cutting sth. askew in the termination at spring body end.
Background technique
Spring is widely used a kind of elastic element in machinery and the electron trade, spring can produce bigger resiliently deformable when stand under load, mechanical work or kinetic energy are converted into energy of deformation, and the distortion of unloading rear spring disappears and reinstatement, and energy of deformation is converted into mechanical work or kinetic energy.Pressure spring is a kind of helical spring that bears pressure in the spring, be a kind of spring that is the most extensively used in all spring kinds, product application range extensively reaches occasions such as electronics, motor, computer, information, steam turbine car, bicycle, hardware ﹠ tools, gift, toy and even national defense industry, because of its design and principle are easy to grasp, production control is also simple.Between the circle of pressure spring and the circle certain clearance is arranged, spring contraction deformation when being subjected to external load stores energy of deformation.And the distortion of unloading rear spring disappears and reinstatement, and energy of deformation is converted into mechanical work or kinetic energy, and purposes is the widest.During fabrication, the spiral ring that coiled separates makes each circle that pitch be arranged, so that stressed contraction maintains the tension force of upholding to two ends, can not be compressed fully by busy hour, must be between number of active coils retention gap, in order to avoid friction or other materials embed, cause fatigue ruption; Its end shape has the two ends ring, two ends polish etc., and sharp edge burr, evagination, the indent that the termination section produces but common end-face structure tends to causes causing that the assembly to being assembled particularly uses the scraping damage that is easy to generate the assembly that is assembled with the assembling of working of plastics, rubber parts.
The model utility content
The utility model sharp edge burr, evagination, indent that to be solution produce because of the spring tip section cause easily causing that the scraping damage criminal facts that the assembly that is assembled is produced influence the quality present situation of assembly, and provide a kind of being difficult in the assembling using process that load module is produced the spring of cutting sth. askew in termination that scraping damages.
The utility model is to solve the problems of the technologies described above the concrete technological scheme that is adopted to be: the utility model is to solve the problems of the technologies described above the concrete technological scheme that is adopted to be: a kind of spring, end portion at the spring body is provided with the angled end-face that is provided with spring body end face bevel, and angled end-face is by the tangential spring body of end face terminad bearing of trend.
As preferably, angled end-face is the whole steel wire oblique section of the end portion of spring body.
As preferably, angled end-face becomes behind the angled end-face more directly the straight section of steel wire to spring body compression direction by the oblique spring body of distal end faces elder generation's terminad bearing of trend.
As preferably, be equipped with angled end-face at the two ends of spring body.
The beneficial effects of the utility model are: change traditional section mode, sharp edge burr, evagination, the indent of avoiding the termination to produce because of section cause with the assembly that uses of assemble particularly with working of plastics, rubber parts scraping caused to the damage of the assembly of assemble use, guarantee the quality of product of the assembly that assembled, improved the Endurance life of the assembly that uses that assembles to a certain extent.

Embodiment
Among the embodiment 1 shown in Figure 1, a kind of spring is provided with the angled end-face 2 that is provided with spring body 1 end face 4 bevels in the end portion 3 of spring body 1, and angled end-face 2 is by the oblique spring body 1 of end face 4 terminad bearing of trends.End face 2 the whole steel wire oblique section of cutting sth. askew for the end portion 3 of the spring body 1 of cutting sth. askew.Be equipped with angled end-face 2 at the two ends of spring body 1.
Among the embodiment 2 shown in Figure 3, angled end-face 2 by 1 one-tenth angled end-face of the end face oblique spring body of 4 first terminad bearing of trends 2 after more directly to the straight section 5 of steel wire of spring body 1 compression direction.All the other are identical with embodiment 1.
Claims (4)
1. termination spring of cutting sth. askew, it is characterized in that: the end portion (3) in spring body (1) is provided with the angled end-face (2) that is provided with spring body (1) end face (4) bevel, and angled end-face (2) is by end face (4) the oblique spring body of terminad bearing of trend (1).
2. according to the described termination of claim 1 spring of cutting sth. askew, it is characterized in that: described angled end-face (2) is the whole steel wire oblique section of spring body (1) end portion (3).
3. according to the described termination of claim 1 spring of cutting sth. askew, it is characterized in that: described angled end-face (2) becomes behind the angled end-face (2) more directly the straight section of steel wire (5) to spring body (1) compression direction by end face (4) the oblique spring body of first terminad bearing of trend (1).
4. according to claim 1 or the 2 or 3 described terminations spring of cutting sth. askew, it is characterized in that: described spring body (1) is equipped with angled end-face (2) at 2 ends of spring body (1).
