Abstract
The utility model discloses a device for increasing the initial tension of a coil spring, which comprises a feeding device, a coil spring cutting device and a coil spring push bending device, wherein the feeding device, the coil spring cutting device and the coil spring push bending device are distributed around the circumference of the coil spring; the feeding device and the cutting device are positioned on the same horizontal plane; the push bending device is arranged above the horizontal plane and forms an acute angle with the horizontal plane; and the device also comprises an advancing device which moves vertically to the plane on which the feeding device and the cutting device are positioned. The device for increasing the initial tension of a coil spring has the advantages of high production efficiency, the initial tension of the coil spring is increased, and the coil spring for increasing the initial tension can be produced on batch.
Description
Technical field
The utility model belongs to the technology that strengthens the wind spring initial tension on the Digital Control Plane Roll-up Spring machine, particularly a kind of increasing wind spring initial tension device.
Background technology
Receive the influence of product with compact structure design concept, receive spatial constraints, under the prerequisite of spring rate regulation, the spring with big initial tension is used in therefore general choosing.Yet to this spring on the market with big initial tension requirement; Particularly the initial tension value is greater than the spring of
; Still there are not special former and automatic processing method; Conventional at present way is to adopt hand-rail type wind spring frock; Manual coiling, this original forming mode makes that labour intensity is very big, production efficiency is very low; Be difficult to produce in batches, simultaneously because people's uncertain factor causes the situation that the product quality fluctuation is big, qualification rate is not high.
The utility model content
The utility model technical problem to be solved is that the increasing wind spring initial tension device that a kind of production efficiency is high, can produce wind spring in batches is provided.
For solving the problems of the technologies described above; The increasing wind spring initial tension device that the utility model provides; It comprises the shearing device of pay-off, wind spring and the bending device of wind spring, and said pay-off, shearing device and bending device circumferentially distribute along wind spring, and said pay-off and shearing device are on a horizontal plane; The bending device is located at the top of horizontal plane and acutangulates with horizontal plane, and it also comprises the advance device perpendicular to the plane motion at pay-off and shearing device place.
As preferably, said advance device comprises servomotor, pallet and slide plate, and said servomotor is connected with pallet, and private clothes driven by motor pallet is perpendicular to the plane motion at pay-off place; Pallet is connected with slide plate slides, adjusts the position of slide plate according to the size in footpath in the wind spring; The end of said slide plate is provided with the crotch that can hold up the wind spring end, and crotch is fixedly connected with slide plate, utilizes crotch that the wind spring end is held up, and imposes on thrust of wind spring, thereby has increased the initial tension of wind spring.
After adopting above structure; The increasing wind spring initial tension device of the utility model compared with prior art; Have the following advantages: after 1, having increased the advance device; According to the requirement control advance amount of wind spring service behaviour, when first lap begins to coil, the feeding of advance device; Impose on additional thrust of wind spring; Wind spring is held up the plane that is higher than the pay-off place, increased the initial tension of wind spring, the highest initial tension value that makes reaches about
; 2, realized mechanized, improved production efficiency greatly, reduced labour intensity, according to statistics, productivity ratio can improve 60%; 3, adopt mechanized to realize the possibility of large-scale production in batches; 4, owing to adopt the mechanization production model, greatly reduce variation and fluctuation that human factor causes, the quality of product also improves thereupon.
Description of drawings
Fig. 1 strengthens the structural representation of wind spring initial tension device for the utility model;
Fig. 2 strengthens the structure cutaway view of wind spring initial tension device for the utility model.
Wherein: pay-off 1, shearing device 2, bending device 3, advance device 4, pallet 5, slide plate 6, crotch 7.
The specific embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Like Fig. 1～shown in Figure 2; It comprises the shearing device 2 of pay-off 1, wind spring and the bending device 3 of wind spring; Said pay-off 1, shearing device 2 and bending device 3 circumferentially distribute along wind spring; Said pay-off 1 and shearing device 2 are on a horizontal plane, and bending device 3 is located at the top of horizontal plane and acutangulates with horizontal plane, and it also comprises perpendicular to the advance device 4 of pay-off 1 with the plane motion at shearing device 2 places.
Preferred as present embodiment; Said advance device 4 comprises servomotor, pallet 5 and slide plate 6, and said servomotor is connected with pallet 5, and pallet 5 is slidingly connected with slide plate 6; The end of said slide plate 6 is provided with the crotch 7 that can hold up the wind spring end, and crotch 7 is fixedly connected with slide plate 6.
In the present embodiment: the size of controlling the advance amount through the adjustment of servomotor relevant parameter.
Job step: steel wire begins coiling, when first lap begins to coil through pay-off 1 under 2 effects of bending device; The 4 beginning feedings of advance device that is to say the plane motion of advance device 4 beginnings perpendicular to pay-off 1 place, and the plane at advance device 4 places in the motion is higher than the plane at pay-off 1 place gradually; Crotch 7 on the advance device 4 is given thrust of wind spring first lap, according to the advance amount of adjusting before the coiling, wind spring is increased a corresponding initial tensile force; After the wind spring first lap finished, 4 moments of advance device were return no longer action; Accomplish up to a wind spring coiling, just can obtain needed increase initial tension wind spring.
In addition, need to prove, the instantiation described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, characteristic and principle are done, include in the protection domain of present technique patent according to the present technique patent.Present technique person of ordinary skill in the field can make various modifications, replenishes or adopt similar mode to substitute to described instantiation, only otherwise depart from the method for present technique or surmount the present technique patent, all should belong to the protection domain of present technique.
