Embodiment Construction

[0022] Such as figure 1 As shown, a continuous non-pickling wire drawing process, its technological process is as follows:

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

[0024] (2) Peeling and grinding: Wind the wire on the four shelling wheels, change the bending rate of the wire to achieve the purpose of peeling, and pull the wire to the grinding mechanism after the shelling is completed. Grinding to remove rust on the wire surface;

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

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

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

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

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, wire drawing of metal wires is generally pickled with acid and then drawn. The process steps are: pickling—neutralization—scrubbing—drawing—reeling. 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 damage to the environment. pollution. [0003] Now there is also a method of wire drawing without pickling, and the process steps are: wire watering and rusting-peeling-drawing-reeling. However, this kind of process production is not continuous, and each process step is carried out independently. The entire operation process is scattered, and it is impossible to form an automated production line. The production efficiency is low, and the wire is easy...
