Description

Technological line for the manufacture of non-metallic fittings

The utility model relates to the manufacturing technology of reinforcing elements used for reinforcing conventional and prestressed building structures and can be used to produce structural material instead of metal and wooden parts used in other industries and in the national economy.

A known production line for the manufacture of non-metallic reinforcement, including: creel with installed bobbins, annealing chamber. an impregnation chamber with a tensioning device, a molding unit with a die block, a prepolymerization chamber and a wrapper, final polymerization chambers, a pulling device and reinforcement winding and cutting units (RU 2075577, Е04С5 / 00, 5/07. 20.03.97). A disadvantage of the known line is the insufficient strength of the periodic profile of the reinforcement, due to the fact that the profile is formed by winding on the core of the braid thread, as well as the presence of a large number of polymerization chambers

The objective of the utility model is to simplify the design of the line and increase the strength of manufactured fittings.

The technical result achieved in the proposed line is the provision of the possibility of molding reinforcement in the form of a monolithic product with simultaneous polymerization in the molding process, which allows to increase the strength of the product and abandon all or most of the polymerization chambers.

The technical result is achieved by the fact that in the production line for the manufacture of non-metallic reinforcement containing a bobbin holder, impregnating chambers, a molding unit including a die block, a prepolymerization chamber and a profile forming device, a node for winding the reinforcement and / or node for cutting the reinforcement, a device for profile molding is made in the form of a heated pipe, detachable along the diametrical plane, with a recess on the inner surface, in shape corresponding to the profile of the reinforcement. The heated pipe may be made of a material having low adhesion when heated. In addition, the line may be provided with a depolymerization chamber installed between the profile forming device and the reinforcement winding unit and / or the reinforcing cutting unit. In addition, the line may

be equipped with a leveling device installed between the bobbin holder and the impregnation chamber.

In FIG. 1 shows a production line for the manufacture of non-metallic reinforcement; figure 2 - node 1 in fig. 1 in section.

The technological line consists of sequentially installed: bobbin holder 1; leveling device 2 for uniform tension of rovings across the section entering the annealing chamber 3; impregnation chamber 4 with a modular device 5; a molding unit consisting of a block of dies 6 of the prepolymerization chamber 7 and a device for forming the profile 8; depolymerization chambers 9; rotary block 10; pulling devices 11, 12; the winding unit 13 and the cutting unit of the reinforcement containing the circular saw 14 with the end starter 15 and the ejector 16.

The line also contains a unit for applying an adhesive or film coating, containing a chamber for applying a polymer binder 17 and abrasive material 18 and a coating chamber 19.

The bobbin holder 1 consists of a base frame, on which metal axes are mounted rotatably, on which bobbins with rovings and tension blocks and leveling combs are installed that specify the direction of movement of the roving.

1 feed chamber 4 is made with a slope of the bottom to the center of the chamber and is equipped with a tension device. The bottom of the camera has a PTFE coating.

The modular device 5 is made in the form of a fluoroplastic plate with holes for drawing off excess binder from the roving.

Block dies 6 consists of a series of sequentially installed metal dies with heating elements and fluoroplastic inserts with decreasing diameters of the conical holes in them and provides the formation of a section of the profile.

The annealing chamber 3 is provided with a high-frequency heater to ensure intensive drying and lubricant removal modes in an automatic mode. The device for forming the profile 8 (figure 2) is made in the form of a heated pipe, detachable along the diametrical plane and having a recess 20 on the inner surface corresponding to the shape of the periodic profile of the reinforcement. The nozzle is made of heat-resistant material, for example, ceramic. The technological line works as follows. On the rotating metal axes of the bobbin holder 1, a row of mineral and

chemical fiber and tension blocks, and on adjacent axes - leveling ridges. Roving from the bobbin passes through the rollers of the tension unit and the leveling ridges, after which the rovings are sent to the leveling device 2, which forms the roving web entering the annealing chamber 3.

In the annealing chamber 3, moisture and lubricant are removed, the processing temperature is up to 200 C. Then the dried roving sheet enters the impregnation chamber 4, filled with a polymer binder with a temperature of up to 60 ° C.

Performing a fluoroplastic lining of the chamber 4 prevents adhesion of the binder to the walls. The tension device and the slope of the bottom of the chamber 4 provides a given optimal mode of impregnation of the roving web with a binder. Next, the web impregnated with a binder passes through a modular device 5, squeezing excess binder, which is returned to the impregnation chambers}, and then crimped on the dies 6, partially forming a section of the reinforcement and entering the prepolymerization chamber 7, where it is partially cured. After that, the molded rod enters the device for forming the profile 8.

The rod is placed between the halves of the heated pipe 8 and crimped by them. In this case, the formation of the periodic profile of the reinforcement takes place and at the same time the polymerization of the reinforcement material takes place. The formation of the profile touched with the reinforcement allows to increase its strength. The heated sleeve serves simultaneously as a polymerization chamber, so that the need for subsequent polymerization chambers is eliminated. If necessary, one depolymerization chamber 9 can be included in the line, into which the reinforcement enters after final molding and polymerization in the device 8. A pulse heating mode is provided in the depolymerization chamber 9.

The cured rod is fed to the cutting unit, on which a circular saw 15 is cut into blanks of measured length and fed by the ejector 17 to the warehouse. The cured rod, if necessary, can be supplied by means of a rotary unit 11 to the unit for winding 13 into the bays.

A film or adhesive coating may be applied to the rod. To this end, a polymer binder and abrasive deposition chamber 17, a film coating chamber 18 and a coating curing chamber 19 are sequentially inserted after the rotary block 10 into the production line. A pulling device 12 or 13 is used for continuous drawing.
