Embodiment Construction

[0022] Such as figure 1 As shown, a continuous pickling-free wire drawing process, the process flow is as follows:

[0023] (1) Pay-off: place the wire to be processed on the pay-off device, and then pull the wire out into the peeling device;

[0024] (2) Shelling and polishing: Wind the wire on the four shelling wheels, and change the bending rate of the wire to achieve the purpose of shelling. After the shelling is completed, the wire is drawn to the polishing mechanism (3) The surface of the wire is processed Grinding to remove rust on the wire surface;

[0025] (3) Wire drawing: After polishing, the wire is drawn to the dry drawing machine and the water tank machine for drawing;

[0026] (4) Take-up: After the drawing is completed, the automatic take-up machine is used to take up the wire.

[0027] The entire process flow will be described in detail below in conjunction with specific process parameters.

[0028] Place the wire with a diameter of 6.5mm to be processed on the wire pa...

Abstract

The invention discloses a continuous acid-washing-free drawing process which comprises the following steps: placing wires to be processed on a despooling machine, drawing the wires out from the despooling machine to enable the wires to be wound around a husking device to conduct husking and guiding on the wires, polishing the wires which are husked through a polishing mechanism to remove rust on the surfaces of the wires, adding drawing powder on the surfaces of the polished wires in a drawing machine to conduct drawing and conducting wire rewinding on the wires which are drawn slim through a wire rewinding machine. The process can effectively remove the rust on the wires by conducting rotating polishing on the wires upwards, frontwards, backwards and downwards through the polishing mechanism. Acid is not used in removing of the rust on the surface of the wires, hydroelectric resources are saved, and pollution of acid mist, waste acid, waste water and the like is removed. The process flow can form a production line to carry out automatic continuous production, and is high in production efficiency, energy-saving and environment-friendly.

Description

Technical field [0001] The invention relates to a wire drawing process. Background technique [0002] At present, the wire drawing of metal wire generally adopts acid for pickling and then drawing. The process steps are: pickling-neutralization-brushing-wire drawing-wire take-up. The wire after this process needs to be annealed to eliminate internal stress. The acid after pickling will penetrate into the material, which will affect the toughness, strength and service life of the material, and the use of a large amount of acid will cause serious environmental problems. Pollution. [0003] Now there is also a method for wire drawing without pickling. The process steps are: watering the wire to rust-peeling-drawing-wire taking up. However, the production of this process is not continuous. Each process step is carried out independently. The entire operation flow is scattered and cannot form an automated production line. The production efficiency is low. In addition, the wire is easil...
