Description

Technical Field

[0001] This utility model relates to the field of stainless steel wire processing technology, specifically to a drawing device for stainless steel wire processing. Background Technology

[0002] Stainless steel wire drawing is a metal plastic processing process in which wire rod or blank is drawn out of the die hole of a drawing die under the action of drawing force to produce small-section steel wire or non-ferrous metal wire. Wires of various metals and alloys with different cross-sectional shapes and sizes can be produced by drawing.

[0003] In the prior art, such as in publication number CN207043041U, a steel wire drawing machine is disclosed. It includes a frame, a drawing mechanism mounted on the frame, a traction mechanism for guiding the drawn steel wire, and a straightening mechanism disposed between the drawing mechanism and the traction mechanism. An elastic anti-detachment wheel is also provided between the straightening mechanism and the traction mechanism. The elastic anti-detachment wheel has an arc-shaped groove, and the straightened steel wire passes under the elastic anti-detachment wheel and is contained within the arc-shaped groove. This steel wire drawing machine effectively prevents the drawn steel wire from loosening and falling off during the cutting process, ensuring the working efficiency of the steel wire drawing machine and improving its safety.

[0004] Although the aforementioned patent incorporates a traction mechanism and anti-detachment wheel, it also has obvious drawbacks. For example, uneven lubrication during the drawing process leads to rapid die wear, poor wire surface quality, and the lubricant's effectiveness is affected by the large amount of impurities it contains after long-term use.

[0005] Therefore, this utility model provides a drawing device for processing stainless steel wire. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a drawing device for stainless steel wire processing, which solves the problems of uneven lubrication in the drawing process, leading to rapid die wear, poor wire surface quality, and the lubricant's reduced lubrication effect due to the large amount of impurities it contains after long-term use.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a drawing device for stainless steel wire processing, including a wire drawing device, wherein a winding drum is provided on the top surface of the wire drawing device, and an installation groove is provided adjacent to the winding drum. A lubrication system is fixedly connected in the installation groove, and a cleaning component is integrated inside the lubrication system.

[0008] The lubrication system includes a pump compartment and a lubrication chamber. The pump compartment is fixed in the mounting groove and is connected to the lubrication chamber through a cleaning component. A pump body is fixed to the bottom wall of the pump compartment. One end of the pump body passes through the lubrication chamber through a connecting pipe and is connected to a pressurizing pipe. An atomizing nozzle is provided at the end of the pressurizing pipe. Perforations for stainless steel wires to pass through are opened on both sides of the lubrication chamber.

[0009] The cleaning assembly includes a filter tube connecting the lubrication chamber and the pump chamber. A stainless steel filter screen, a sintered metal filter element, and a ceramic filter element are arranged sequentially from top to bottom inside the filter tube. The top of the filter tube passes through the lubrication chamber and the bottom is connected to the pump body.

[0010] Preferably, the pressurizing tube has a tapered structure with its inlet diameter being larger than the outlet diameter of the connecting tube, and its outlet end is connected to the atomizing nozzle to increase the lubricating oil pressure.

[0011] Preferably, the cleaning component has a multi-stage filtration structure consisting of a coarse stainless steel filter screen, a fine metal sintered filter element, and an ultra-fine ceramic filter element arranged sequentially inside the filter tube.

[0012] Preferably, when the pump body is running, a negative pressure is generated in the filter tube, so that the lubricating oil in the lubrication chamber flows sequentially through the coarse stainless steel filter screen, the fine metal sintered filter element, and the ultra-fine ceramic filter element before entering the pump body for circulation.

[0013] Preferably, the perforated inner wall of the lubrication chamber is provided with a wear-resistant bushing, and the axis of the perforation is inclined at an angle to the spray direction of the atomizing nozzle.

[0014] Preferably, the lubrication chamber, pump chamber, and cleaning components are integrated in the same mounting slot, and the filter pipe penetrates vertically through the lubrication chamber and pump chamber to realize the lubricating oil circulation path.

[0015] Beneficial effects

[0016] This invention provides a drawing device for processing stainless steel wire. Compared with the prior art, it has the following advantages:

[0017] 1. This stainless steel wire drawing equipment, through the gradually tapering conical structure design of the pressure tube and the atomizing nozzle, pressurizes and atomizes the lubricating oil pumped by the pump body to evenly cover the surface of the stainless steel wire. Combined with the wear-resistant bushing and inclined guide of the perforated inner wall of the lubrication chamber, it significantly improves the penetration and uniformity of the lubricant in the contact area between the steel wire and the die, thereby reducing the frictional heat of drawing and the wear of the die, while improving the surface finish of the stainless steel wire.

[0018] 2. This stainless steel wire drawing equipment, through the synergistic effect of the multi-layer filtration structure in the cleaning component, and driven by the negative pressure of the pump body, the lubricating oil used in the lubrication chamber undergoes multi-stage gradient filtration, which effectively intercepts metal debris, oxides and tiny particulate impurities, ensuring that the lubricating oil circulating to the atomizing nozzle maintains a high level of cleanliness, extending the service life of the lubricating oil and maintaining stable drawing process conditions.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-4 The first embodiment is shown: a drawing device for stainless steel wire processing, including a drawing device 1, a winding drum 2 on the top surface of the drawing device 1, an installation groove adjacent to the winding drum 2, a lubrication system 3 fixedly connected in the installation groove, and a cleaning component 4 integrated inside the lubrication system 3; the lubrication system 3 includes a pump chamber 31 and a lubrication chamber 32, the pump chamber 31 is fixed in the installation groove and communicates with the lubrication chamber 32 through the cleaning component 4, a pump body 33 is fixed on the bottom wall of the pump chamber 31, one end of the pump body 33 passes through the lubrication chamber 32 through a connecting pipe 34 and is connected to a pressure pipe 35, the end of the pressure pipe 35 is provided with an atomizing nozzle 36, and the lubrication chamber 32 has perforations on both sides for stainless steel wire to pass through.

[0027] Specifically, during the drawing process, the pump body 33 delivers lubricating oil to the pressure pipe 35 with a tapered structure through the connecting pipe 34. As the pipe diameter gradually decreases, the lubricating oil pressure increases significantly. Subsequently, the high-pressure lubricating oil forms uniform atomized particles through the atomizing nozzle 36 and covers the surface of the stainless steel wire. At the same time, the wear-resistant bushing on the perforated inner wall of the lubrication chamber 32 guides the stable movement of the steel wire by reducing its frictional resistance. The inclined angle design between the perforation axis and the spray direction of the atomizing nozzle 36 allows the atomized lubricating oil to penetrate directionally along the direction of the steel wire's travel, ensuring that the lubricating oil fully enters the contact interface between the steel wire and the mold. This reduces the accumulation of frictional heat and uniformly lubricates the inner wall of the mold, ultimately improving the surface quality of the stainless steel wire and extending the mold's life.

[0028] In this embodiment, the cleaning component 4 includes a filter tube 41 that connects the lubrication chamber 32 and the pump chamber 31. A stainless steel filter screen 42, a metal sintered filter element 43 and a ceramic filter element 44 are arranged sequentially from top to bottom inside the filter tube 41. The top end of the filter tube 41 passes through the lubrication chamber 32 and the bottom end is connected to the pump body 33.

[0029] Specifically, when the pump body 33 starts, a negative pressure is formed in the filter tube 41, which drives the lubricating oil containing metal debris and impurities in the lubrication chamber 32 to flow from top to bottom through the multi-stage filtration structure of the cleaning component 4: first, the coarse stainless steel filter screen 42 intercepts large metal debris and oxides, then the fine metal sintered filter element 43 further removes medium and fine particulate impurities, and finally the ultra-fine ceramic filter element 44 filters out tiny particles. The clean lubricating oil after three stages of filtration re-enters the pump body 33 and is sprayed out through the atomizing nozzle 36. This multi-stage gradient filtration mechanism effectively prevents impurities from re-entering the lubrication system 3, maintains the stability of lubricating oil viscosity and cleanliness, thereby ensuring consistent lubrication performance during the drawing process and reducing the equipment failure rate caused by oil contamination.

[0030] Figures 1-4 The second embodiment is shown. The main difference from the first embodiment is that the pressure pipe 35 has a tapered structure with a larger diameter at the inlet end than at the outlet end of the connecting pipe 34. The outlet end is connected to the atomizing nozzle 36 to achieve the increase of lubricating oil pressure. When the pump body 33 is running, a negative pressure is generated in the filter pipe 41, so that the lubricating oil in the lubrication chamber 32 flows through the coarse stainless steel filter screen 42, the fine metal sintered filter element 43 and the ultra-fine ceramic filter element 44 in sequence before entering the pump body 33 for circulation.

[0031] Specifically, through the tapered structure design of the pressure pipe 35, the pressure of the lubricating oil increases significantly as the cross-sectional area gradually decreases when it flows through the connecting pipe 34 into the pressure pipe 35. The high-pressure lubricating oil forms uniform and fine atomized particles through the atomizing nozzle 36, which has stronger penetration when covering the surface of the stainless steel wire, effectively reducing the dry friction between the steel wire and the die (not shown) during the drawing process, lowering the local temperature and improving the lubrication efficiency. During the operation of the pump body 33, a stable negative pressure is formed in the filter pipe 41, which forces the lubricating oil used in the lubrication chamber 32 to flow directionally through the multi-stage filtration structure, realizing the dynamic circulation and real-time purification of the lubricating oil, avoiding oil deterioration caused by impurity deposition, and reducing the frequency of manual cleaning.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working Principle: Pump body 33 delivers lubricating oil through connecting pipe 34 to tapered pressure pipe 35. Due to the reduced cross-sectional area, a pressurization effect is generated, causing the lubricating oil to form high-pressure atomized particles through atomizing nozzle 36, which are evenly sprayed onto the surface of the stainless steel wire passing through the perforations of lubrication chamber 32. The wear-resistant bushing on the inner wall of the perforation of lubrication chamber 32 reduces the frictional resistance of the steel wire. Combined with the inclined angle design between the perforation axis and the spray direction of atomizing nozzle 36, the lubricating oil is directionally guided to wet the mold contact interface along the direction of the steel wire's travel, forming a continuous lubricating film, which significantly reduces the heat of drawing friction and mold wear. At the same time, during the operation of pump body 33, a negative pressure is formed in filter pipe 41, driving the lubricating oil containing metal debris in lubrication chamber 32 to flow from top to bottom through the multi-stage filtration structure of cleaning component 4: coarse filter stainless steel filter screen 42 intercepts large particles of impurities, fine filter metal sintered filter element 43 captures medium particles, and ultra-fine filter ceramic filter element 44 filters out micron-sized dust. The lubricating oil purified by the three stages re-enters pump body 33 for recycling, ensuring the stability of lubricant cleanliness.
