Description

In modern construction, often, reed shields are used to avoid the use of scarce building materials. The process j of making reed shields by hand is considerably time consuming, so it is necessary to strive to fully mechanize the production of rock shield boards.

According to the invention, there is provided a machine for cutting strips made from reeds into which two pairs of cartridges with blades are applied, reciprocating in the vertical direction for clamping transverse gaskets pressed into the treated reed strip, and when the cartridges with blades are displaced in the horizontal direction. the direction is carried out by cutting the longitudinal wires connecting the reed, and bending the cut ends into transverse wires.

In FIG. 1 is a front view of the machine; FIG. 2 is the same side view; FIG. 3 is the same in section along the line AB in FIG. one; FIG. 4 is a side view of the cartridges clamping a strip of reeds; FIG. 5 is a side view of a roller abutting against a clamped gasket; FIG. b- front view of one of the patrci knives; FIG. 7 is the same side view; FIG. 8 is the same top view; FIG. 9-front view of the second

knife patrons; FIG. 10 is the same side view; FIG. 11 is the same top view.

The frame of the proposed machine (Figs. 1-3) consists of racks 7 connected to each other by ties. The pillars / frame are connected by parallels 25, in which crossbars 2, 3 can be reciprocated in vertical direction, connected by pulls 11, 12 to the arms 9 of shaft 4 and carrying fixed cartridges 24 with knives. The shaft 4, which communicates the movement of the crossbars 2, 3, is associated with a clamp clamp 10 equipped with a roller 20 interacting with a cam / 9 mounted on the shaft 3 fastened in bearings 6. The shaft 5 is connected to the handle 18, during which the shaft 4, which is connected to the shaft 5, this system receives swinging movements.

On the shaft 5 there are also eccentrics 13, connected by rods with sliders 21 carrying the knife holders 23, guided in parallel between the crossbars 2, 3, in order to bring them closer or away from the fixed crossbars 2, 3 cartridges 24. The blades of cartridges 23 vi 24 have a corresponding outline and scissors with blades 16, 26 (Fig. 6 - P) scissors for cutting the reed shield wire and curvilinear ribs 27-

edges for bending the ends of the cut wires.

A strip 28 of reeds, connected in advance by wires 30 and provided with transverse gaskets 7 pressed into it (Figs 1-3, 4, 5), is located between the upper and lower pairs of crossbars 2, 3. After the strip 28 is set, the handle 18 moves, which rotates the shaft 5, transmitting, on the one hand, swinging movements to the shaft and, on the other hand, informing the horizontal movements of the chuck holders 23 with knives.

When the shaft 4 is moved, in turn, the crossbars 2, 3, which are associated with it, move in the vertical direction, the rollers 8 of which abut against the gasket 7 pressed into the strip 28 of the reed and clamp the latter. While moving the cartridges 23, their knives together with the blades of the cartridges 24 are cut by blades 16, 2 (5 (Fig. B-P) of the wire 30 (Fig. 4) and curvilinear ribs 27 bend the cut ends 29 onto the transverse wires 22 that tie the reed.

Since the strip of the camouflage 28 usually moves during cutting, the machine frame will also move with it along the beams 17 in view of the clamping of the strip 7 of the strip 7 with the rollers 8. After finishing the work and releasing the strip 28 from the clamp, the frame of the machine will return to its original position cargo 7.5 (Fig. 3).

The subject matter of the invention.

Claims (6)

1. A machine for cutting strips made from reed into parts, characterized by the use of two pairs of cartridges 23 vi 24 a with knives (Fig. B-11) receiving reciprocating up and down movements for clamping The transverse gaskets 7 pressed into the strip (Figs. 4 and 5) and the relative displacement in the horizontal direction for cutting the idol wires 30 and bending the cut ends 29 (Fig. 4) onto the transverse wires. 2. In the machine tool according to claim 1, a mechanism for communicating to the cartridges with knives of vertical movement, characterized by the use of shaft 4 (FIG. -3) with arms 9, connected by bars / 7 and / 2 with bearing cartridges crossbars 2, 3, guided in parallel to the machine bed parallel to which shaft 4, oscillating movements from the handles 18 through the shaft 5 are communicated with the cam 19 acting on the roller 2 (9-bar thrust 10 connected to the shoulder on the shaft 4. 3. In the machine tool according to claim 1, a mechanism for the relative horizontal displacement of the chucks with knives, characterized by the use on the shaft 5 of eccentrics 13 (Fig. 1-3), connected with their pads with jumps 27 carrying the chucks 23 guided in parallel crossbars 2, 3, which device has the aim of bringing together the cartridges 23 with the cartridges fixed on the crossbars 2, 3 and moving away from them. 4. In the machine tool according to claim 1, use the rollers 8 connected with the upper cross bar 2, 3 to abut the gasket 7 (FIG. 4) and clamp the strip 28 from the reed stone. 5. In the machine tool according to claim 1, use knives that form blades 75 and 26 (fig. 6-11) scissors for cutting wires and curvilinear ribs of the 27-edge for bending the ends of the cut wires. 6. In the machine tool according to claim 1, the application of the load 75 (Fig. 3) to return the machine to its original position after moving it along the beams 77 by a moving strip, clamped by the roller 8 during the period of operation of the knives.
