Description

The invention relates to equipment for the manufacture of long products from layered composite materials and can be used in the processing of composite materials, for example, based on thermoplastic binders.

A device for forming long products from layered composite materials is known, containing two mandrels and a steel tape fixed to them with the possibility of alternately rewinding under tension to crimp the long material, as well as tempering and

receiving mechanisms.

Among the disadvantages of the known device, in addition to increased production space and energy costs, the spread of properties and the instability of the physico-mechanical characteristics of the materials of products produced on mandrels at the same time should be attributed to them.

The purpose of the invention is to improve the quality of products.

This goal is achieved by the fact that in the device for forming long products from layered composite materials containing two mandrels and a steel tape fixed to them with the possibility of alternately rewinding under tension to crimp the long material, as well as the release and receiving mechanisms according to the invention, the mandrels are installed parallel one over

another with the possibility of mutual contact, and the dispensing and receiving mechanisms of long material are located on opposite sides of the steel strip in the contact zone of the mandrels.

In FIG. 1 is a schematic diagram of a device, a general view; figure 2 is the same, a top view; in Fig.Z - the same. side view.

A device for forming products from a layered composite material based on a polymer binder comprises mandrels 1 and 2, steel tape 3, which are capable of alternately winding under tension on mandrels 1 and 2 of steel tape 3 with tape materials, and individual drives 4 and 5 and 2.

The coils 6 and 7 of the steel strip 3 have opposite threads on the mandrels 1 and 2, the transition section between them, on which the steel tape 3 reverses its direction, is in the contact zone.

Mandrels 1 and 2 of the device are installed in parallel, one opposite the other, tempering mechanisms with bobbins 8 and 9, supporting tape materials are located on opposite sides of them.

The operation of the device is as follows.

In the initial position, the steel strip 3 is completely wound on one of the mandrels 1 or 2 with the fastening of its free end to the other mandrel.

The heating of the mandrels 1 and 2 is turned on, their drives 4 and 5 are turned on. Between turns b or 7 of the steel strip 3, from the side of the release mechanism 8 or 9, respectively, tape material is supplied to one of the mandrels until it is wound together with the entire steel tape 3, while the winding of the turns of the steel tape 3 together with the tape material is produced by direct contact with another mandrel having a supply of free turns of steel tape 3. Then, after the curing of the tape material, synchronous switching is performed when the drives 4 and 5 rotate the mandrels 1 and 2 in the opposite direction, from the opposite side tape material is fed between the turns of the steel tape 3 to the mandrel from which the turns of the steel tape 3 were wound, from the mandrel on which the tape material was already wound, t .e. continuous winding is carried out in the form of a finished tape product onto the bobbin of the release mechanism with constant contact of mandrels 1 and 2 through turns b and 7 of steel strip 3.

Thus, the process of winding tape materials and the selection of finished tape products is carried out continuously, the finished product is removed, another bobbin with tape material is installed and the process continues with the curing of the products on mandrels.

The manufacture of tape products from composite materials based on woven reinforcement and thermoplastic binder on an experimental sample of the device showed the high quality of the material and its effectiveness.

In this case, the tape material is crimped due to the tension of the steel strip and the normal pressure of the mandrels in contact with each other. In addition, such arrangement of units reduces the floor space.
