Description

Technical Field

[0001] This utility model relates to the field of tungsten wire cold drawing technology, specifically a tungsten wire cold drawing control device. Background Technology

[0002] Tungsten wire is a metallic material with high hardness, high strength and good conductivity. Traditional hot drawing process has low production efficiency, low die life, low yield and high production cost. Cold drawing of tungsten wire is a processing method that uses a drawing die to plastically deform tungsten wire at room temperature to obtain the required shape and size. It is mainly used to manufacture tungsten wire diamond wire busbar.

[0003] During the cold drawing process of tungsten wire, lubricant is needed to reduce friction, reduce die wear, and control processing temperature. However, during the cold drawing process, as the drawing speed changes, the lubricant adhering to the surface of the tungsten wire may be thrown off the wire surface due to the drawing speed, which can easily affect subsequent drawing operations.

Detailed Implementation

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example

[0019] Please see Figs. 1-3 A tungsten wire cold drawing control device includes a base 1, a cold drawing mold 2 is arranged on the upper side of the base 1, a storage box 3 is arranged on the upper side of the cold drawing mold 2, a delivery pump 4 is arranged on the upper side of the storage box 3, baffles 5 are arranged on both sides of the cold drawing mold 2, a driving component 6 is arranged on the outer side of the baffles 5, the driving component 6 is connected to the driving tooth 7, an arc frame 8 is arranged on the inner side of the baffles 5, one side of the arc frame 8 passes through the baffles 5 and is connected to the driven tooth 9, and atomizing nozzles 10 are evenly arranged on the inner side of the arc frame 8.

[0020] A limiting component is provided on the other side of the arc frame 8. A collection trough 11 is provided on the upper side of the base 1. Guide slopes 12 are provided on both sides of the collection trough 11. A first filter plate 13 and a second filter plate 14 are respectively inserted into the upper side of the guide slopes 12. The interior of the arc frame 8 is hollow. The delivery pump 4 is connected to the interior of the arc frame 8 through a hose 15.

[0021] The limiting component includes a rotating disk 16 disposed on the other side of the arc frame 8, a limiting frame 17 inserted into one side of the rotating disk 16, and a ring of limiting holes corresponding to the limiting frame 17 disposed on the outer side of the baffle 5.

[0022] It should be noted that during the cold drawing process of tungsten wire, lubricant is needed to reduce friction, reduce mold wear, and control processing temperature. At this time, the delivery pump 4 can be controlled to run, draw lubricant from the storage tank 3, and send it into the arc frame 8 through the hose 15. Finally, the lubricant can be sprayed out through multiple sets of atomizing nozzles 10, so that the lubricant droplets are evenly distributed on the surface of the tungsten wire, which is convenient for subsequent cold drawing operations.

[0023] However, in actual operation, the cold drawing speed may vary. When the cold drawing speed is increased, the tungsten wire is drawn too quickly, and the lubricant droplets may be thrown off the wire surface, which may affect the subsequent cold drawing effect. At this time, the drive component 6 is controlled according to the cold drawing speed of the tungsten wire, and the active gear 7 and the driven gear 9 cooperate to drive the arc frame 8 and the atomizing nozzle 10 to adjust the angle, so that the initial velocity direction of the lubricant droplets is closer to the axis of the tungsten wire, reducing splash loss and ensuring the subsequent cold drawing effect.

[0024] After the angle adjustment is completed, the limiting frame 17 can be inserted through the rotating disk 16, and the limiting frame 17 can be inserted into the limiting hole, so that the angle of the arc frame 8 can be fixed and the arc frame 8 can be prevented from becoming loose.

[0025] Meanwhile, the splashed lubricating fluid droplets will enter the collection tank 11 for collection. The guide slope 12 can make the droplets quickly merge and form a liquid flow. Then, it can be filtered through the first filter plate 13 and the second filter plate 14. Finally, it can flow into the collection tank 11 through the discharge port for collection, which is convenient for subsequent processing.

[0026] Both the first filter plate 13 and the second filter plate 14 are provided with handles 19 on their upper sides, making it easy for operators to remove the first filter plate 13 and the second filter plate 14.

[0027] A liquid level observation port is provided on the front side of the storage tank 3, and a liquid replenishment port 20 is provided on the upper side of the storage tank 3 to facilitate the replenishment of lubricating fluid.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
