DE3622529A1 - Wire redrawing apparatus - Google Patents

Abstract

For redrawing wire, the invention proposes an apparatus by means of which the wire can be deposited in a drum or as a ring in a basket or wound directly onto a spool. Since it was hitherto possible to perform these various deposition functions only with different apparatuses, the invention leads to a considerable saving on the machine capacity required.

Description

The invention relates to a device for Draw wire and for optional storage of the wire in the barrel, as a ring in a basket or directly wound up a coil consisting essentially of one Machine frame with a stationary drawing die, one Drawing ring, a continuous cleaning device, one Deflection roller, a straightening unit, an extraction ring, one Wire guide and a driven plate with vertical Axle for holding a barrel or basket.

Such devices are used for the finishing of Wires, at the same time the specified diameter manufactured with great precision, the desired Strength values set and a wire with the desired surface is generated. It will also be on such devices the wire in the usual containers stored in the barrel, as a ring or coil. So far were for different storage types separate Pulling devices with matched Wire guide means required. For one and the same So the end product had to be two or three Pulling devices are provided to all of to be able to realize the types of storage requested by the customer. Such a machine capacity is a matter of course exploited economically only if all three Storage types are requested about the same number of times. Becomes Sometimes only one type of shelf is made, 2/3 of the existing machine capacity unused and arise Bottlenecks when such conditions last longer.

It is therefore the task of designing a device for drawing wire that is suitable for all types of storage in order to be able to achieve a better utilization of the machine capacity, which is no longer dependent on customer requirements. Of course, there should be no loss of product quality. In particular, for all types of storage - as with conventional machines - perfect wire guidance must be ensured, ie the wire must be under sufficient but not too great tension all the way and wire-wire contact must be excluded.

To solve this problem, a device of suggested type, which thereby is characterized that the pull ring and the pull ring on the same horizontal shaft of a drive are arranged and the same outer diameter have that the drawing ring with a spreader Guide grooves and the pull ring with a pressure roller is assigned to non-profiled cylinder surface and that also a winding device with a horizontal shaft is provided, the drive is train-controlled.

Expedient are still on the device Guide means for forming a wire loop arranged. The pull-out ring can also be a Spreading roller with guide grooves to be assigned. Furthermore is provided that the wire optionally from the spreader or from the pull-out ring to the guide means Winding device can be performed. Drawing ring, The pull-out ring and the spreading roller are expediently made of ceramic material while the pressure roller advantageously consists of plastic. To the  Possible uses of the device according to the invention to improve further, it is envisaged that they will be on rollers is designed to be movable.

Further details and advantages of the device according to the invention are explained in more detail with reference to FIGS. 1 and 2.

Fig. 1 shows a greatly simplified side view of a device for drawing wire while in

Fig. 2 shows the same device in front view and partly in section along the line AA of FIG. 1.

The device according to the invention essentially consists of a machine frame ( 1 ) with a stationary drawing die ( 2 ), a drawing ring ( 3 ), a continuous cleaning device ( 19 ), a deflecting roller ( 4 ), a straightening unit ( 20 ), an extracting ring ( 5 ), a wire guide ( 6 ) and a driven plate ( 7 ) with a vertical axis for receiving a barrel ( 8 ) or a basket. In addition, guide means ( 15 ) and ( 16 ) are provided for forming a wire loop ( 21 ). In addition, in the illustrated embodiment, also the pull-out ring (5) is associated with a spreader (17) with guide grooves. The wire ( 18 ) can optionally be guided from the spreading roller ( 17 ) or from the pull-out ring ( 5 ) via the guide means ( 15 ) and ( 16 ) to the winding device ( 12 ). The drawing ring ( 3 ), the extraction ring ( 5 ) and the spreading rollers ( 10 ) and ( 17 ) consist of ceramic material, preferably ceramic ZT 35 from Feldmühle. The pressure roller ( 11 ) is made of plastic, preferably Vulkolan with a Shore hardness of 85.

The entire device is mounted on rollers ( 22 ) and can therefore be easily moved to any suitable workstation if required.

From the illustration according to FIG. 2 it can be seen that the machine frame ( 1 ) is essentially L-shaped, with all the devices for pulling and winding being arranged on the vertical leg, while in the horizontal leg the turntable ( 7 ) for receiving a barrel ( 8 ) or a basket is stored. Both the pull ring ( 3 ) and the pull ring ( 5 ) are mounted on the shaft ( 9 ) of the drive ( 9 a ). The spreading rollers ( 10 ) and ( 17 ) are arranged at the same height but laterally offset (cf. FIG. 1). In addition, part of the guide means ( 15 ) can be seen, which is required to form the wire loop ( 21 ). In addition, you can see the pressure roller ( 11 ), which is required for a defined guidance of the wire over the pull-out ring when it is to be placed in the barrel ( 8 ) or in the basket. On the shaft ( 3 ) of the drive ( 14 ) the winding device ( 12 ) is arranged, which is required for the storage type "winding" shown in FIGS . 1 and 2.

With the device according to the invention is a machine created all the functions in wire drawing fulfilled and in particular for all three occurring Storage types is suitable. This can Wire drawing made much more economical will. Machine capacities that were previously only in view to the changing wishes of customers regarding the Storage type that had to be kept is no longer available required.
