Description

Technical Field

[0001] This utility model belongs to the technical field of cold drawing equipment, specifically a tungsten wire cold drawing device with lubricant filtration. Background Technology

[0002] In the cold drawing process, the circulating lubricating fluid is prone to generating black flocculent precipitates under high-temperature conditions. Long-term accumulation of these substances can lead to mold and pipeline blockage, valve wear, and reduced lubrication performance, resulting in quality problems such as wire breakage, dimensional deviations, and surface defects. Currently, methods such as sedimentation separation, coarse filtration devices, and periodic manual cleaning are commonly used to remove impurities. However, these methods have limited effectiveness in removing fine impurities (such as metal powder and oxide particles) and cannot guarantee the cleanliness of the lubricating fluid. Therefore, existing technologies struggle to achieve an effective balance between filtration accuracy and system stability. An improved solution that introduces a high-efficiency filtration method into the return fluid pipeline of the cold drawing machine is urgently needed to address the problem of insufficient impurity removal in the circulating lubricating fluid. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a tungsten wire cold drawing device with lubricant filtration, which effectively solves the problem of poor filtration effect of existing cold drawing devices on circulating lubricant.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a tungsten wire cold drawing device with lubricant filtration, comprising a cold drawing machine, wherein a liquid storage tank and a circulation machine are provided at the top of the cold drawing machine, the circulation machine is connected to the cold drawing machine through a liquid inlet pipe, the liquid storage tank is connected to the cold drawing machine through a liquid return pipe, and a filtration mechanism is provided on the liquid return pipe;

[0005] The filtration mechanism consists of a filter pipe, a limiting guide support, an inclined tube, a filter element, and a sealing cap. The filter pipe is connected to the return pipe. The limiting guide support is welded to the middle of the top of the filter pipe. The inclined tube is welded to the middle of the bottom of the filter pipe. The filter element is inserted into the inclined tube and the filter pipe and fits against the limiting guide support. The sealing cap is connected to the end of the inclined tube away from the filter pipe.

[0006] The filter element consists of a support mesh cover, a filter mesh cover, a metal connecting ring, and a glass fiber filter element.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 5 This invention discloses a tungsten wire cold drawing device with lubricant filtration, comprising a cold drawing machine 1, a liquid storage tank 2 and a circulation machine 3 at the top of the cold drawing machine 1, the circulation machine 3 being connected to the cold drawing machine 1 via an inlet pipe 4, and the liquid storage tank 2 being connected to the cold drawing machine 1 via a return pipe 5, the return pipe 5 being equipped with a filter mechanism 6, the filter mechanism 6 comprising a filter pipe 7, a limiting and guiding support 8, an inclined pipe 9, a filter element 10, and a sealing cap 11, the filter pipe 7 being connected to the return pipe 5, and the limiting and guiding support 8 being welded to the middle position of the top of the filter pipe 7, thereby limiting the filter element 10 and guiding the lubricant to enter the filter element 10. Inside the filter pipe 7, the inclined tube 9 is welded to the middle of the bottom end of the filter pipe 7. The filter element 10 is inserted into the interior of the inclined tube 9 and the filter pipe 7 and fits against the limiting guide support 8. The sealing cap 11 is connected to the end of the inclined tube 9 away from the filter pipe 7. The filter element 10 is composed of a support mesh cover 12, a filter mesh cover 13, a metal connecting ring 14 and a glass fiber filter element 15. The filter mesh cover 13 is located inside the support mesh cover 12. An annular inner cavity 16 is formed between the support mesh cover 12 and the filter mesh cover 13. The metal connecting ring 14 is located at the top of the annular inner cavity 16 and is welded to the support mesh cover 12 and the filter mesh cover 13. The glass fiber filter element 15 is inserted into the interior of the annular inner cavity 16.

[0023] During the operation of the cold drawing machine 1, the lubricating fluid circulates for lubrication and cooling. When the lubricating fluid flows back through the return pipe 5, it is filtered by the filter mechanism 6. The lubricating fluid enters the interior of the filter pipe 7, then enters the interior of the filter element 10, and flows out from the side of the filter element 10. At this time, the filter screen 13 and the glass fiber filter element 15 achieve filtration on both sides, which can filter out fine impurities and improve the cleanliness of the lubricating fluid. The filtered lubricating fluid continues to flow back along the return pipe 5. When it is necessary to clean or replace the filter element 10, the sealing cover 11 is removed and the filter element 10 is taken out.

[0024] Flanges 17 are welded to both ends of the filter pipe 7 and to the return pipe 5 near the filter pipe 7, which facilitates the installation of the filter pipe 7.

[0025] The sealing cap 11 is threaded to the inclined tube 9, and an O-ring 18 is provided between the sealing cap 11 and the inclined tube 9 to improve the sealing performance of the connection between the sealing cap 11 and the inclined tube 9.

[0026] A drain pipe 19 is fixedly installed at the bottom end of the sealing cover 11. A conical rubber sealing head 20 is installed inside the sealing cover 11. A positioning rod 21 connected to the conical rubber sealing head 20 is slidably inserted at the center position of the end of the sealing cover 11 away from the inclined pipe 9. A pressing plate 22 is fixedly installed at the end of the positioning rod 21 away from the conical rubber sealing head 20. A spring 23 is sleeved on the positioning rod 21 between the pressing plate 22 and the sealing cover 11. An O-ring 24 that fits against the positioning rod 21 is installed at one end inside the sealing cover 11.

[0027] When an emergency cleaning of impurities is required, push the pressing plate 22 directly. The pressing plate 22 moves the positioning rod 21, and the spring 23 contracts. The positioning rod 21 moves the conical rubber sealing head 20, so that the conical rubber sealing head 20 forms a gap with the inner wall of the sealing cover 11, allowing the lubricant and impurities to be discharged through the drain pipe 19, thereby achieving the emergency cleaning function. After cleaning, release the pressing plate 22, and the spring 23 will reset the device. The O-ring 24 can improve the sealing performance of the connection between the positioning rod 21 and the sealing cover 11.

[0028] In operation, the filtration mechanism, consisting of a filter pipe, limiting guide support, inclined tube, filter element, and sealing cap, can be connected to the return pipe. Filtration is achieved as the lubricating fluid flows back through the return pipe, preventing impurities from entering the storage tank and the circulation machine. The filter element, composed of a support mesh, filter mesh, metal connecting ring, and glass fiber filter element, provides dual filtration of the lubricating fluid, effectively removing fine impurities and improving its cleanliness. The sealing cap, threadedly connected to the inclined tube, allows for easy disassembly, facilitating filter element removal, cleaning, or replacement. The inclusion of a drain pipe, conical rubber sealing head, positioning rod, pressing plate, and spring allows for quick cleaning of the filter element's interior without disassembling it, enhancing operational convenience.
