FI92805C - Device for winding metal wire / rod - Google Patents

Description

! 92805 APPARATUS FOR COOKING YARN / BARS AND ARTICLES.

For example, when continuously casting a metal wire / rod, a simple and reliable winder is required, i.e. a winder, which bends the wire with a constantly changing bending radius into as tight a winding as possible. The yarn is made at a maximum of 5 meters per minute, but with many threads at the same time.- The desired coil weighs 2-5 tons; the coil must be easily movable by forklift or crane due to its size and tightness.

In known solutions, the wire is pushed by means of a motor-driven traction roller 10 followed by a separate bending roller into a rotating receiving frame (either driven by the wire's own thrust or by a separate motor) in which the coil is formed.Especially when thin (<8 mm) when pushing a heavy swirl. The frame must rotate at varying speeds following changes in the bending radius of the wire, and its weakness is based on the high quality requirements of the rotating mechanism. When the weight of the coil is several tons, the device is expensive, in addition, the central bearing of the pallet lifts the pallet off the floor 20 or requires immersion, if the removal of the coil is to be done with a fork carriage, for example.

Now, in the present invention, the receiving platform of the coil does not rotate, but a normal: transport platform that is at rest on the floor can be used as the receiving platform. The present invention 25 is as set forth in the claims and shown in Figures 1 (side) and 2 (top), with reference to which the operation of the device is as follows:

For example, a continuously cast wire arrives from a casting machine to a vertically operating push roller 3, the rollers 30 of which push the wire guide / bending arc 4. This bending arm is mounted to rotate about a vertical axis below the push roller and has e.g. rollers to guide the wire. The bending arm is shaped so that the wire, when passing through it, receives a suitable bend to form the coil 35. At the end of the bending arm, there is an adjustable bending roller 5 with which the bending radius of the wire can be adjusted

Claims (5)

2 92805 continuously changes to form a tight heavy coil. The motor moving the bending roller can be adjusted by a computer program according to a suitable bending program. 40 After passing through the bending arm, the wire falls freely on the transport base, creating a intended coil. When the wire remains in a stationary coil on the platform, the bending arm rotates at the speed of movement of the wire against the incoming direction of the wire. 45 When the coil has grown to the intended size, the wire is cut, the transport pallet with the coils 2 is moved away and a new one is replaced. If required for transport / storage, the coil can be formed in a canopy or cage-like frame made for this purpose. Claims: Apparatus for winding a metal wire / rod, consisting of a motorized push roller and a rotatably mounted guide / bending arm, characterized in that the guide / bending arm of the device 1 rotates freely under the control of a wire 55 and at a speed given by the wire. 2. The last part of the guide / bending arm in the direction of travel of the wire can be adjusted so that the diameter of the wire loop formed can be changed as required. 60 In the case of upstream vehicles with a metal wire / Stange with a motor vehicle in the form of a roller coaster and a sheave of the headlamps from Figure 1 on the basis of the ledgers / collars and the three-way rails can be adjusted to the diameter of the three-wheeled tracks after use.
