Description

The grids are pulled by the drum 29 (Fig. 2) j, which receive rotation from the electric motor, through the gearbox 30. Through the same gearbox, the drum 31 receives the drive 5, to which the product roller 32 is pressed with the load 33. The wire is passed to the drum 31 under the pressure roller 34.

The device operates as follows. The invention relates to the manufacture of woven nets for reclamation, industrial and civil construction.

The purpose of the invention is expansion. technical capabilities and increased reliability.

The device for the fabrication of the wire mesh consists of a frame 1 on which the coils 2 for the wire, the tension rollers 3 and the block 4 are located.

twisting the wires before the parallel branches enter the wires 35 into the inclined channels up to the stop, after which the contact 36 mounted on the platform 16 is closed and the command is given not to be kinematically due to the operation of the electric motors 24,

spreading the twist along the entire length of the wire and forming the mesh profile of two parallel wires 35 along both ends of the twist-knot 8 knots 8 are clamped with limiters 15 of the twist.

the cell and the removal of the cell after twisting the wires and rotate in the cracks 13, containing 1x fixed sections 14 of the guide surfaces of the twist T5 movable limiting forks, mounted on a lifting platform 16 moving vertically along the columns 17 (Fig. 4), gesture - Simultaneously with the closure of the contact of the platform 16 connected with the carriage 6 of the hydrocyte, the platform 16 begins with a slow-moving cylinder 18, the carriage 6 is provided with a role-. Lennoy movement of the carriage 6 (Fig. 2, 19 (Fig. 2 and 4) for horizons and 4) along the guides 20 power tal reciprocating hydraulic cylinders 2 K. Pass some movement along the guides 20 hydrodistance, the carriage 6 presses the carriages drive cylinders 21. The speed switch 37 provides the leather to the driving gears 11 (Fig. 4) 1 to force the actuators to operate hydraulically through sprockets 22, pillows 18, which lower the platform 16 and release the grid moving in the movement limiters 7, from movable limit stops 15 55 twists and twisting wire assemblies 8, and power 1: cylinders 21 quickly return carriage 6 to its original position, at which the limit switch 38 is turned on

fixed rigidly on the same shaft with them, using a chain transmission 9 through a gearbox 23 by an electric motor 24.

In hydraulic cylinders 18 and 21 (Fig. 2), oil is pumped from tank 25 through throttle 26 by gear pump 27 driven by electric motor 28. Netting is carried out by drum 29 (Fig. 2) j received rotation from electric motor through reducer 30 the reducer receives the drive drum 31, onto which the product roller 32 is pressed with a load 33. A net is wound on the drum 31, passing under the pressure roller 34.

The device works as follows. Wire 35 (Fig. 1) of the coils

spreading the twist along the entire length of the wire and forming the mesh profile two parallel wires 35 along both ends of the twisting knots 8 are clamped with limiters 15 of the twist.

Simultaneously with the closure of the contact by the platform 16, the slowed-down movement of the carriage 6 (Figures 2 and 4) along the guides of 20 power cylinders 2 K begins. Pass a distance, the carriage 6 presses the limit switch 37 and gives a command to trigger power hydraulic pillows 18, which lower the platform 16 and free the grid, moving in the limiters 7 of the movement, from the movable forks, the twist limiters 15, and the wire twist assemblies 8, and the power 1: the cylinders 21 quickly return the carriage 6 to its original position at which rum switch on limit switch 38

actuation of the power cylinders 18 to the elevation of the platform 16. Thus, the cycle is repeated. At the same time, the time spent on moving two cells of the grid is less than the time taken for the carriage 6 for slow moving forward and fast returning back. When the start button is turned on, a command is issued to drive the rotation of the drums 29 and 31 (fig. 2) through the reducer 30, the drums rotate slowly without stopping from the beginning to the end of the process of making the mesh roll.
