Description

The invention relates to devices for the manufacture of reinforcement, for example, for concrete, from non-metallic materials.

As a prototype, the description of the invention "Technological line for the manufacture of composite reinforcement" to the patent No. 2287646, IPC E04C 5/07, publ. November 20, 2006 (according to the first option). The aforementioned production line contains creel with roving rods, leveling device, annealing chamber, impregnation bath with tension device, squeezing device, molding unit, spiral winding device, polymerization chambers, pulling device, cutting unit. The molding unit is made in the form of a matrix with longitudinal channels installed directly in front of the spiral winding zone, and the distance from the winding point of the winding bundle of the composite reinforcement is equal to: (1 ÷ 10) d, where d is the diameter of the reinforcement. The squeezing device is made of elastic elastic material and is installed in front of the matrix, and the leveling device is made in the form of a comb, in which the number of grooves is not less than the number of channels in the matrix. The matrix has 2-10 channels evenly spaced around the central guide. The guide matrix is made in the form of a cone or a truncated cone. The squeezing device is made in the form of a plate with slots, the number of which is equal to the number of matrix channels. The leveling device is made of bent wire. The mechanism of the tensioner is located above the impregnation bath.

Signs that are common to the prototype and the claimed device consist in the presence of a frame with roving bobbins, a leveling device, a drying chamber, an impregnating bath with a tension device, a squeezing device, a molding unit with a winder, polymerization chambers, a pulling mechanism and a cutting unit.

The reason that prevents obtaining a technical result in a well-known technical solution, which is provided by a useful model, is the multichannel and conicity of the matrix, which determines the presence of excesses of roving harnesses. This design does not allow to increase the pulling speed due to the possibility of scoring and loosening of the harness due to alternating loads from kinks in the matrix. In addition, the slow cooling of the reinforcement after the polymerization chambers to the cutting unit also inhibits the speed of broaching the reinforcement.

The problem, which the utility model is aimed at, is to increase the productivity of the installation.

The technical result that mediates the solution of this problem is to increase the speed of broaching reinforcement.

The technical result is achieved by the fact that in a known installation for the manufacture of composite fittings, including a frame with roving bobbins, a leveling device, a drying chamber, an impregnating bath with a tension device, a squeezing device, a forming unit with a winder, polymerization chambers, which are sequentially located and connected in one technological line , pulling mechanism, cutting unit, according to a utility model, the molding unit is made in the form of an external rotating pipe with a winder installed on it, to the end of which d spacing collar is attached with a slot for the passage of winding the harness and is connected with it a matrix with the through hole and inside the outer rotatable tube mounted stationary pipe. In this case, the outer rotating tube, the fixed tube, the spacer sleeve and the matrix are installed coaxially. The technical result is achieved by the fact that the installation is additionally equipped with a cooling device located between the polymerization chambers and the pulling mechanism.

Since all elements of the molding unit, the outer rotating tube with the winder, the inner stationary tube, the spacer sleeve and the matrix are aligned, i.e. the holes of both pipes, the spacer sleeve and the matrix are on the same geometric axis, then the bundles and fittings passing through them along a straight path are not subject to kinks and hooks, which allows to increase the pulling speed, and hence the installation performance. The presence of a cooling device shortens the overall technological cycle somewhat, by reducing the cooling time of the reinforcement before cutting, and ultimately also aimed at enhancing the technical effect, i.e. to increase the speed of broaching.

New features of the claimed technical solution consist in the execution of the molding unit in the form of an external rotating pipe with a winder installed on it, in connecting to the pipe end of the sleeve with a slot for the passage of the winding harness, in connecting to the matrix sleeve with a through hole, in the installation inside the outer rotating pipe motionless pipe. In this case, the outer rotating tube, the fixed tube, the spacer sleeve and the matrix are installed coaxially. Equipping the installation with a cooling device located between the polymerization chambers and the pulling mechanism is also new.

The utility model is illustrated by drawings, where:

figure 1 - shows the installation diagram;

figure 2 - molding unit in section.

The installation for manufacturing composite reinforcement consists of sequentially installed frames 1 with roving bobbins, leveling device 2, drying chamber 3, impregnation bath 4 with tensioning device 5, squeezing device 6, molding unit 7 with winder 8, polymerization chambers 9, cooling device 10, pulling mechanism 11 and the node 12 cutting. The forming unit 7 consists of an outer rotating pipe 13 on which a winder is mounted 8. A spacer 14 with a slot 15 is connected to the end of the outer rotating pipe 13 to pass the winding bundle from the winder 8 to the valve core. The matrix 16 is connected to the other end face of the spacer sleeve 14 with a through hole. A fixed tube 17 is installed inside the outer rotating pipe. All components of the molding unit 7, namely, the outer rotating pipe 13, the fixed pipe 17, the sleeve 14 and the matrix 16, are mounted coaxially, i.e. their geometric axes are located on one straight line, providing a rectilinear trajectory of movement in the molding unit 7 bundles forming a rod, and reinforcement.

Installation for the manufacture of composite reinforcement works as follows. Rows made of mineral, such as glass or polymer, fibers from the bobbins of the frame 1 pass through a leveling device 2, which has the additional function of dividing the roving canvas into separate bundles. After the leveling device 2, the tows enter the drying chamber 3, where moisture is removed. Then the roving ropes enter the impregnation bath 4 filled with a polymer binder, are impregnated with it and pass through the tensioner 5 located under the bath 4. After the tensioner 5, the roving ropes pass through the squeezing device 6 made of elastic material, where excess binder is separated, which returns to the bath. Next, roving harnesses enter the stationary tube 17 and there, thanks to the binder, are combined into a rod, which then moves to the distance sleeve 14. In the distance sleeve 14, a wire comes through the slot 15, coming from the rewinder 8, which, rotating with it, carries out on the moving Spiral winding rod. Next, the wound rod passes through the through hole of the matrix into the polymerization chambers 9, where it is subjected to heat treatment, then through the cooling device 10, the pulling mechanism 11 and the cutting unit 12. In the cooling device 10, a gas or liquid medium is used as cooling, depending on the material of the composite reinforcement.
