Abstract

The invention relates to a device for trimming wire mats. The invention has for its object to bring a device used, with which the wire meshes of different sizes and grid are made without Nibbelueberstaende. According to the invention, this is achieved by the device consisting of two lower blades, the male connector, the deflectors and the left and right feed devices. During the cutting process, the male connector is precisely defined over the wire mat lowered and the deflectors adjust them. The feed device exerts a pressure on the wire mat, whereby it hangs something and rests exactly on the male connector. After the first step, the male connector is raised again, the second feed device acts on the wire mat and the male connector lowers over this. Now the pre-adjustment and the cutting process are done again. Fig. 1 {wire mat; nibbling; Cutter; Scissors; Male connector; Lower blade; Upper blade; deflector; Feeder; Buffer loop}

Description

Field of application of the invention The invention is used in the manufacture of wire meshes of various dimensions. Characteristic of the known state of the art It is known that the separation of wire mesh by means of conventional impact shears, which by a pulse from the Welding machine is triggered takes place. This technology requires a double Nachnibbeln. Further, by cutting devices of the company "Schlatter" known that idle strokes are carried out by means of control,

which guarantee a uniform distance between the wires, ie from one grid to the other, and only then

Cut done. With this solution, in addition to the great expense of control and mechanics to an increased Wire consumption. Even by the fixed positioner can not occur due to the welding process delay in the grid

be compensated, a cutting of the cross wire is possible.

According to DE PS 2809 299 is a pair of scissors for separating the parallel longitudinal elements of gratings or gratings

known, in which a fixed horizontal cross-sectional guide bar with ordered, comb-like counter-holder and a movable cutter bar, are arranged on the comb-like knife, is provided. The leadership and the

Blades are slidable in a machine frame in the vertical direction. At both ends of the guide bar is ever a stop surface. Both bars are guided between two sliding surfaces. According to DE OS 2439185 a scissors is known, which is placed on the grid to be cut through. With this pair of scissors

the guide bar is provided with equally spaced counter-teeth arranged with comb teeth.

The cutter bar also has comb teeth. The solutions shown in the prior art do not correspond in their function to the conditions of use or

cause too much technical effort and material consumption.

Object of the invention

The aim dor invention is to bring a device for trimming wire mats in application, the use of which the wire mats are made without Nibbel supernatants, thereby eliminating physically heavy work, increases the effectiveness, improves quality and material can be saved.

Explanation of the essence of the invention Dor invention is based on the object to bring a device used, with the produced wire mesh in

different sizes and pitches without nibble supernatants directly in the technological process and with the

Device upstream production facilities are made exactly matched. According to the invention this is achieved in that the device in its basic construction of lower blades, a male connector, Deflectors and left and right feed devices consists. The device arranged behind the mesh welding machine picks up the wire mat with its longitudinal and transverse wires. After welding the transverse wires to the longitudinal wires, the grids are laterally and within the mat benibbelt and

thus produced the first finished measure. For trimming the longitudinal wires is a pair of scissors, consisting of a top and

Bottom knife, arranged. The cutting itself is done so that the Meeserleiste defined exactly in height over the longitudinal wire of the wire mat

is lowered, whereby the deflectors pre-adjust the wire mat.

By means of precisely matched pressure is pressed by the feed device on the right on the wire mat and so long,

until a slight bulging occurs, or by a corresponding counter-pressure, the feed device is turned off, whereby all transverse wires of the wire mat abut exactly on the male connector.

Then the knife bar is shut down, the first cut is made. Now, the knife bar is raised to about 2 mm above the cutting plane, then the feed device is operated on the left and at the same time lowered the male connector to 1/10 mm above the wire mat.

The deflectors realize the pre-adjustment of the wire mat with defined pressures against the male connector, the pressure is increased until a slight bulging occurs, then the second cut is carried out.

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawing shows

Fig. 1: Overall view of the device. The device consists of the feed devices left and right 4.5, the deflectors 6, the male connector 7 and the Lower blades 9. The feed devices 4.5 convey the wire mesh 1 with longitudinal and transverse wires 2, 3, precisely defined to the interface. Due to the special design of the deflector 6, which are arranged on the male connector 7, takes place when shutting down the Knife strip 7, the Vorjustage of the wire grid 1 in the first and second cutting process. _; To push the feed device 4, 5, the wire mesh 1 against the male connector 7 is a constantly different Transport route necessary. This is ensured by the formation of the buffer loop 8.

Claims (1)
