Abstract
The utility model discloses a spring with outward buckled ends. The spring is characterized in that an outward buckled end (3) bent from the inside diameter of the cylinder of the spring body to the outside diameter direction thereof is connected at the tail end part (2) of the spring body (1), and an outward buckled end bent toward the outside diameter direction of the cylinder of the spring bodyis also connected at the other tail end part of the spring body (1). The bending distance of the outward buckled ends from the inside diameter of the cylinder of the spring body to the outside diameter direction thereof is one third to one half of the line diameter of the wire of the spring body. The requirement on the assembly of the outer surface of the spring and a component can be well satisfied, especially when the spring is used with the line diameter thereof as the screw pitch and matched with outside assembling, the scrape of the sharp edges of the ends to the thread and the teeth canbe better avoided, and the service reliability of the product can be improved.
Description
Technical field
The utility model relates to a kind of spring, especially a kind ofly carries out the spring that sticks up outside 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 state-owned pitch, 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., the sharp edge burr that the termination section produces but common end-face structure tends to causes causing the assembly to being assembled, when particularly assembling is used as the pitch coupling for the spring wire footpath, the scratch of the easier double thread of termination sharp edge, tooth line; Or use the scraping damage that more 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 that the termination section produces when to be solution because of spring use as outer assembling causes the screw thread that the assembly that is assembled is produced, the scraping of tooth line, the quality present situation that the damage present situation influences institute's load module easily, and provide a kind of in the assembling using process, to load module, or can not produce working of plastics, rubber parts outside the termination of scraping damage and stick up spring when particularly assembling is used as the pitch coupling for spring wire footpath.
The utility model is to solve the problems of the technologies described above the concrete technological scheme that is adopted to be: stick up spring outside a kind of termination, 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 the spring 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 matching requirements of spring outer surface and assembly can be better met, when particularly outer assembling is used as the pitch coupling for the spring wire footpath, the scratch of termination sharp edge double thread, tooth line can better be avoided taking place.
As preferably, the outer warping end head is 1/3～1/2 of spring body wire rod line footpath from spring body cylindrical inner diameter to the being folded to distance of external diameter direction.
As preferably, the outer warping end head begins the invagination position from end portion and plays the external formed angular range of cylindrical center of interior end points on the termination and spring body that sticks up of spring at 15～25 degree.
The beneficial effects of the utility model are: by the termination of spring being carried out the outer structure setting of sticking up, can better meet the matching requirements of spring outer surface and assembly, when particularly outer assembling is used as the pitch coupling for the spring wire footpath, can better avoid taking place the scratch of termination sharp edge double thread, tooth line, improve the product operational safety, sticking up setting simultaneously outside the termination also provides operation easily for producing assembling.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation that colludes spring in the utility model termination.
Embodiment
Among the embodiment shown in Figure 1, stick up spring outside a kind of termination, the end portion 2 of spring body 1 is connected with the outer warping end head 3 that is folded to spring body 1 cylindrical outer diameter direction from spring body cylindrical inner diameter, and another end portion of spring body 1 is connected with the outer warping end head that is folded to spring body cylindrical outer diameter direction equally.The outer warping end head is 2/5 of spring body wire rod line footpath from spring body cylindrical inner diameter to the distance that is folded to of external diameter direction.Outer warping end head 3 is spent 20 with formed angle 4 scopes of cylindrical center of spring body from the interior end points 5 that end portion begins to play on the spring body 1 outer warping end head 3 the invagination position.
Claims (3)
1. stick up spring outside a termination, it is characterized in that: the end portion (2) of spring body (1) is connected with the outer warping end head (3) that is folded to spring body (1) cylindrical outer diameter direction from spring body cylindrical inner diameter, and another end portion of spring body (1) is connected with the outer warping end head that is folded to spring body cylindrical outer diameter direction equally.
2. according to sticking up spring outside the described termination of claim 1, it is characterized in that: described outer warping end head is 1/3～1/2 of spring body wire rod line footpath from spring body cylindrical inner diameter to the distance that is folded to of external diameter direction.
3. according to sticking up spring outside claim 1 or the 2 described terminations, it is characterized in that: described outer warping end head (3) is rolled over the interior end points (5) that plays on spring body (1) the outer warping end head (3) position and is spent 15～25 with the formed angular range of cylindrical center of spring body outside end portion begins.
