Uncoiling and wire drawing device

Abstract

The invention discloses an uncoiling and wire drawing device. The uncoiling and wire drawing device comprises a base, a feeding frame, an uncoiling mechanism, a wire drawing mechanism, a wire coilingmechanism and a control mechanism, wherein the uncoiling mechanism comprises a first uncoiling part, a longitudinal straightening part, a transverse straightening part and a material conveying part; the wire drawing mechanism comprises a wire drawing bin, wire drawing wheels, wire drawing liquid sprayers, a filter screen and a liquid collecting groove; and the wire coiling mechanism comprises a wire winding rotary shaft, a fixing seat and a wire winding motor. According to the uncoiling and wire drawing device, an upper positioning roller and a lower positioning roller are arranged to cooperate with each other, relative positions and rotating speed of the upper positioning roller and the lower positioning roller are adjusted according to the size of a wire rod, so that stability of the material feeding is guaranteed; the first uncoiling part, the longitudinal straightening part, the transverse straightening part and the material conveying part are arranged to cooperate with one another, the wire rod is straightened in all directions, and convenience is provided for subsequent processing; and the wire drawing wheels and the wire drawing liquid sprayers are arranged to cooperate witheach other, wire drawing operation is carried out on the wire rod in a closed environment, noise and dust pollution are reduced, the environment is protected, and the wire drawing effect is good.

Description

【Technical field】 [0001] The invention relates to the technical field of wire rod processing, in particular to an uncoiling wire drawing device. 【Background technique】 [0002] In order to save costs, hardware processing companies began to purchase large-scale coiled and packaged metal materials, and process and cut them into strips by themselves; these metal coils are not only heavy in tonnage, but also large, and manual operation is neither convenient nor safe. When the coil is placed on the uncoiler, due to the different diameters of the inner circumference of the coil itself, the coil often slips when it is rotated and uncoiled on the main shaft, and the existing uncoiler does not have a good straightening effect on the wire, which affects the follow-up The processing quality of the wire. [0003] After the wire is uncoiled, it is often necessary to draw the wire to make the diameter, roundness, internal metallographic structure, surface finish and straightening of the ...

Problems solved by technology

But in the actual operation process, especially in the steel wire drawing process of the dry wire drawing machine, the temperature at the deformation position of the steel wire drawing can rise to 500 ° C, and the lubricating powder used in the dry wire drawing machine is usually at a temperature higher than 200 ° C. Softening occurs at ℃, and the lubricating powder attached to the surface of the steel wire after softening will adhere to the surface of the wire drawing die when it passes through the drawing die, so that the lubricating powder loses its lubricating effect, thereby reducing the drawing efficiency of the dry wire drawing machine

At the same time, after the wire drawing machine stops and cools down, the softened lubricating powder attached to the surface of the wire drawing die will harden again, resulting in the formation of irregular protrusions on the surface of the wire drawing die, which will affect the wire drawing effect when the wire drawing machine is running again. The wire drawing efficiency of the wire drawing machine is reduced, and on the other hand, the energy consumption of the wire drawing is increased
