Description

Spring thread-laying device

Technical field

A kind of spring thread-laying device is the utility model is related to, belongs to composite fiber winding technology field.

Background technology

In composite fiber winding product, the angle by reducing fiber and central axis is required in some cases To improve product axial tensile-strength.Existing wind is that fiber is wrapped on core rod by wrapping machine, such to twine Winding technologe can only typically be wound in 30 °~90 ° of angular range, and too small angle wound can cause fiber slippage, therefore nothing Method carries out the winding of more low-angle.

Thread-laying device is needed according to the section of product come the fixed shape and size of itself, it is therefore desirable to is prepared a large amount of different Thread-laying device.This causes thread-laying device quantity larger, and manufacturing cost rises and is not easy to manage.

At core rod both ends that fibre bundle is spacing by thread-laying device, stopping means needs to account for less circumferential sky in itself Between, and less circumferential spacing is kept, therefore self-strength is not high enough, colliding with for careless manipulation may cause Needle with hanging thread to be broken. Simultaneously as spacing position is very more and size is small, cause processing and manufacturing cost higher.

Utility model content

For in the prior art the defects of, the purpose of this utility model is to provide a kind of spring thread-laying device.

The utility model is achieved through the following technical solutions：

The utility model provides a kind of spring thread-laying device, and it includes fixed plate, if the edge of the fixed plate is provided with Dry locating slot, the locating slot is interior to be provided with fixing hole, and spring is equipped with the fixing hole.

Preferably, the section of the spring is rectangular.

Preferably, 1 fewer than the quantity of locating slot of the spiral quantity of the spring.

Preferably, the quantity of the fixing hole is two.

Compared with prior art, the utility model has following beneficial effect：

According to the spring thread-laying device that the utility model is related to, the spring silk of hanging wire spring is an entirety, improves extension The intensity at line position, thinner hanging wire spring can be formulated according to production requirement and more dense fiber is spacing, be advantageous to small Angle wound it is spacing.Further, locating slot and fixing hole can directly be set with core rod both ends, save fixed plate.Thus, It can meet that low-angle winding Arbitrary Shape Cross Section is free of deep camber concave inward structure (such as rectangle, circle, polygon, ellipse) Product.

Embodiment

The utility model is described in detail with reference to specific embodiment.Following examples will be helpful to this area Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that to ability For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made. These belong to the scope of protection of the utility model.

As shown in Fig. 1~8, a kind of spring thread-laying device provided by the utility model includes fixed plate 1, fixed plate 1 Edge is provided with locating slot 11 of some length equivalent to fixed plate thickness, is provided with two fixing holes 12 in locating slot 11, two solid Determine the both ends that hole 12 is located at locating slot 11 respectively, spring 2, the fixed packet that spring 2 passes through fixing hole 12 to be equipped with fixing hole 12 It is trapped among the edge of fixed plate 1.

The section of spring 2 is rectangular, and the both ends of spring 2 respectively have one section of part to stretch out.

1 fewer than the quantity of locating slot 11 of the spiral quantity of spring 2.

During assembling, due to the spiral quantity of spring fewer than the quantity of locating slot 1, one that spring one end is inserted in fixed plate Individual fixing hole, then will be caught in fixing groove per coil spring successively, finally, by the spring other end insert another in fixed plate fix Hole.

Use principle of the present utility model is：Separation is fixed by setting different width of the spring size a and fixed plate Size b, it is identical with product winding process angle that deflection angle α values are set by α=arccos (b/a)；Simultaneously as hanging wire spring It is connected, improves the intensity of itself, therefore thinner spring silk can be selected, accordingly, it is capable to farthest reduces spring to fibre The interference of dimension.

Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, This has no effect on substantive content of the present utility model.
