Description

Technical Field

[0001] The utility model relates to the field of metal wire drawing equipment, in particular to a wire drawing machine pretreatment device for removing iron wire oxide scale. Background Art

[0002] Metal mesh is needed for turnover box products in the logistics and warehousing industry. The raw material is generally "iron wire coil" blank. Due to certain requirements on the diameter, roundness, smoothness, etc. of the metal mesh products, the blank needs to be drawn 2-5 times.

[0003] However, the surface of the iron wire blank is generally attached with an oxide layer. Direct wire drawing will affect the finish of the final product and easily scratch the wire drawing die, which cannot meet the wire drawing requirements. Therefore, the iron wire blank is pretreated before the wire drawing process. The pretreatment process includes two steps: removing the oxide layer and lubricating. The existing wire drawing machine pretreatment device is a fixed bracket of a fixed roller group inlaid with bearings. The roller group includes 2-5 rollers of the same structure (such as Figure 1 The iron wire blank is wound and stretched between rollers to remove the oxide layer attached to the surface. The pre-treated iron wire then enters the wire drawing powder box for lubrication.

[0004] However, the existing wires after pretreatment are straight and smooth, with low friction and poor powder adhesion, which leads to insufficient lubrication and affects the quality and appearance of the products after the wire drawing process. At the same time, the wire drawing machine is subject to large friction during processing and is easily damaged, requiring frequent maintenance. Utility Model Content

[0005] The utility model aims to provide a wire drawing machine pretreatment device for removing iron wire oxide scale, so as to increase the powder content of the iron wire blank and improve the lubrication effect, thereby solving the problems mentioned in the background technology.

[0006] In order to solve the above problems, the technical solution adopted is: a wire drawing machine pretreatment device for removing oxide scale of iron wire, comprising a fixed bracket and 2-5 rollers fixed in the middle of the fixed bracket, each of the rollers is connected to the fixed bracket through a rolling bearing, and a groove for the iron wire blank to pass through is opened on the rim of each roller; a plurality of protrusions are evenly distributed along the circumference of the rim of the last roller in the feeding direction, and the iron wire blank bypasses between the rollers during feeding, and when passing the last roller, the iron wire blank advances from the outside in close contact with 1-3 of the plurality of protrusions, thereby changing the shape of the iron wire blank.

[0007] Specifically, the groove for the iron wire to pass through is an annular square groove.

[0008] Furthermore, a plurality of through holes are opened in the wheel rim of the roller, the protrusions are placed in the through holes, and both ends of the protrusions are welded to the wheel rim or connected to the wheel rim through a blocking piece.

[0009] Furthermore, the blocking member is a thread plug.

[0010] Preferably, the bumps are columnar, and the number of the bumps is 4-6.

[0011] During feeding, the iron wire blank material directly enters the wire drawing powder box filled with lubricating powder in a wave shape after leaving the wire drawing machine pretreatment device.

[0012] It should be noted that the wire drawing powder box is available through commercial channels, and its structural composition is part of the prior art. The wire drawing die is also an existing product, which is fixed to one end of the wire drawing powder box, and its design structure does not need to be adjusted whether the iron wire blank is fed in a straight line or in a wave shape.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The device arranges a plurality of protrusions on the rim of the roller so that the iron wire entering the wire drawing powder box is wavy, thereby increasing the friction between the iron wire and the lubricating powder, thereby increasing the amount of powder attached, enhancing the lubrication effect, and reducing the wear of the iron wire and the wire drawing die during wire drawing, thereby extending the service life of the wire drawing die and reducing the equipment maintenance cost.
