Description

Technical Field

[0001] This application relates to the field of steel wire drawing technology, and in particular to a water tank wire drawing nozzle dust suction head, wherein the testing device is used for online cleaning of metal dust inside the nozzle. Background Technology

[0002] In the process of producing steel wire cord from water tank wire drawing, after the steel wire is drawn through the finished die, the finished die needs to be fixed with the help of the mastic structure, and the drawn steel wire passes through the circular cavity in the center of the mastic.

[0003] Traditional manufacturing processes commonly use tungsten carbide dies as drawing tools, but this method has significant shortcomings, primarily manifested in large fluctuations in wire diameter, making it difficult to meet the specifications required for high-precision production. To improve product dimensional accuracy, existing technologies have introduced polycrystalline dies to replace tungsten carbide dies for drawing, effectively improving the stability of wire diameter and overcoming previous challenges in precision control.

[0004] However, the application of polycrystalline molds also brings new challenges. Because their core size is significantly smaller than that of tungsten carbide molds, the steel wire is in closer contact with the core during the drawing process, resulting in increased metal dust. This dust tends to accumulate in the circular cavity of the mold core, and as the accumulation increases, it adversely affects the heat dissipation of the mold and the drawing process, thereby affecting product quality.

[0005] Currently, methods for cleaning dust accumulation are inadequate. Operators must stop the machine and disassemble the entire mastic assembly to clean its internal cavities. This offline cleaning method is cumbersome, involving multiple steps such as disassembly, cleaning, and reassembly. It not only causes production interruptions and affects continuous operation but also significantly reduces production efficiency while increasing time and labor costs.

[0006] Therefore, developing a specialized tool capable of online cleaning of metal dust inside the magnification layer during the wire drawing process in water tanks has become an urgent need to solve current technical bottlenecks, ensure production continuity, and improve overall efficiency.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0008] The purpose of this application is to provide a water tank brushed metal dust suction head for online cleaning of metal dust inside the brushed metal part.

[0009] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution: This utility model provides a water tank suction head, including: a suction nozzle, a handheld end, and a suction device connection port; the handheld end is fixedly connected to the suction nozzle, and the included angle between the two is 90° to 135°; a wire receiving groove is provided on one axial side of the suction nozzle, and the wire receiving groove extends from the front end of the suction nozzle to the connection with the handheld end; the suction device connection port is located on the handheld end away from the suction nozzle.

[0010] Furthermore, the suction nozzle has a cylindrical structure.

[0011] Furthermore, the diameter of the suction nozzle is set to be smaller than the inner diameter of the circular cavity in the center of the nozzle.

[0012] Furthermore, the width of the wire receiving groove is 1.2 to 1.5 times the diameter of the largest wire produced.

[0013] Furthermore, the inlet of the wire receiving groove is chamfered.

[0014] Furthermore, the chamfer is 45°.

[0015] Furthermore, the handheld end and the vacuum nozzle are integrally molded.

[0016] Furthermore, the bending angle between the handheld end and the vacuum nozzle is 130°; the length of the handheld end is designed to be 90-110mm, and a diamond-shaped anti-slip texture is set on its surface.

[0017] Compared with the prior art, the beneficial effects achieved by this application are as follows: By designing a suction head with a specific bending angle, operators can easily apply force, allowing the suction nozzle to penetrate into the interior of the mastic cavity for precise dust adsorption. Furthermore, a through-hole steel wire receiving groove on the suction nozzle ensures stable embedding of the moving steel wire during the wire pulling process, enabling online cleaning of mastic dust without requiring machine shutdown or equipment disassembly. This significantly improves production efficiency and ensures continuous and stable operation of the production line. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1

[0022] like Figure 1-2 As shown, this embodiment provides a water tank suction head, including: a suction nozzle 1, a handheld end 2, and a suction device connection port 4; the handheld end 2 is fixedly connected to the suction nozzle 1, and the included angle between the two is 90° to 135°; a wire receiving groove 3 is provided on one axial side of the suction nozzle 1, and the wire receiving groove 3 extends from the front end of the suction nozzle 1 to the connection point with the handheld end 2; the suction device connection port 4 is provided on the handheld end 2 at the end away from the suction nozzle 1.

[0023] The suction nozzle 1 is used to clean dust from the nozzle area. The handheld end 2 is easy for workers to hold. The suction device connection port 4 adopts a standardized quick-connect structure, and the interface specifications are matched with the dust collection device used in the workshop, which can achieve quick connection. The handheld end 2 and the suction nozzle 1 are bent at an angle of 90° to 135°. This angle design is convenient for operators and can avoid interference between the handheld end 2 and the wire drawing equipment. The wire receiving groove 3, which is opened on one side of the suction nozzle axis, extends from the front end of the suction nozzle 1 to the bent connection part with the handheld end 2, thus forming a complete wire avoidance channel, so that the wire can be embedded in it when cleaning dust, thus eliminating the need to stop the machine for cleaning.

[0024] By setting a suction nozzle 1 with a certain bending angle and a handheld end 2, and opening a through-type steel wire receiving groove 3 on the suction nozzle 1, the suction nozzle 1 can be stably embedded in the moving steel wire, thereby realizing online cleaning of mastic dust.

[0025] The vacuum nozzle 1 has a cylindrical structure.

[0026] The diameter of the suction nozzle 1 is set to be smaller than the inner diameter of the circular cavity in the middle of the nozzle.

[0027] The cylindrical suction nozzle 1, with a diameter slightly smaller than the inner diameter of the circular cavity in the center of the mastic, ensures that it can smoothly extend into the mastic cavity and maintain a reasonable gap with the inner wall; the length of the suction nozzle 1 is designed to reach the bottom of the mastic cavity, ensuring the cleaning effect of dust at the bottom of the mastic cavity.

[0028] The width of the wire receiving groove 3 is 1.2 to 1.5 times the diameter of the largest wire produced.

[0029] The width of the wire receiving groove 3, which is set at 1.2 to 1.5 times the diameter of the wire, ensures that wires of all production specifications can be stably embedded, while avoiding excessive gaps that would affect the dust collection effect.

[0030] The inlet of the wire receiving groove 3 is chamfered.

[0031] The chamfer is to facilitate the quick sliding of the moving steel wire into the steel wire receiving groove 3.

[0032] The chamfer is 45°.

[0033] The chamfer was optimized to 45° based on actual measurements.

[0034] The handheld end 2 and the vacuum nozzle 1 are integrally molded.

[0035] The handheld end 2 and the suction nozzle 1 adopt an integrated molding structure to ensure structural strength and dimensional accuracy; and use wear-resistant nylon material, or similar material with moderate hardness, high temperature resistance and certain elasticity, to prevent hard abrasion and high temperature melting when the suction nozzle 1 comes into contact with the high-speed running steel wire, and to reduce rigid collision damage with equipment parts.

[0036] The bending angle between the handheld end 2 and the vacuum nozzle 1 is 130°; the length of the handheld end 2 is designed to be 90-110mm, and a diamond-shaped anti-slip texture is set on its surface.

[0037] The bending angle between the handheld end 2 and the vacuum nozzle 1 has been optimized to 130° through actual testing. At this angle, the operator can easily exert force to operate. The handheld end 2 is designed to be 90-110mm long and has a diamond-shaped anti-slip texture on the surface to improve grip stability in wet and slippery environments. Example 2

[0038] Taking a working condition with a mastic cavity inner diameter of 24 mm and a steel wire diameter of 0.38 mm as an example, the specific implementation method of this application is described as follows: The suction nozzle 1, with a cylindrical structure, has a diameter approximately 4 mm smaller than the inner diameter of the bottom of the mastic cavity. In this embodiment, the inner diameter of the cavity is 24 mm, and the diameter of the suction nozzle 1 is set to 20 mm to ensure smooth insertion and to form an appropriate gap with the inner wall of the cavity, facilitating airflow during suction. The length of the suction nozzle is designed to fully contact the bottom of the mastic cavity, thereby achieving thorough removal of metal dust deposited at the bottom and avoiding cleaning dead zones. The handheld end 2 and the suction nozzle 1 are manufactured using an integrated molding process, which ensures the overall structural strength and dimensional accuracy while avoiding strength loss due to assembly gaps. The bending angle between the two has been optimized to 130° through actual operation testing, making it easier for operators to apply force. The length of the handheld end is set at 90–110 mm, and the surface is processed with diamond-shaped anti-slip texture to enhance grip stability in wet and slippery environments. The width of the wire receiving groove is set at 1.3 times the diameter of the largest wire produced. When producing wires with a maximum diameter of 0.38mm, the groove width is set at 0.50mm. This ensures stable embedding of wires of different specifications while avoiding negative pressure loss due to excessive gaps. The groove inlet features a 45° chamfer with a length of 4mm, complemented by a 0.5mm radius arc transition. This allows high-speed wires to slide quickly into the groove, achieving convenient "push-in" alignment and significantly reducing operational difficulty.

[0039] The working principle of this application is as follows: First, connect the suction head's suction device connection port 4 to the workshop's suction equipment, start the suction equipment, and generate negative pressure at the suction nozzle 1. Next, the operator stands to the side of the stretching equipment, holds the handle end 2 with one hand, aligning the 45° chamfered part of the suction nozzle 1 with the steel wire, and gently pushes it along the direction of the steel wire's movement. The chamfer guides the steel wire smoothly into the steel wire receiving groove 3. The entire alignment process takes no more than 5 seconds. Then, slowly push the suction nozzle 1 into the mastic cavity until it contacts the bottom, hold for 1 second, and then perform two reciprocating movements up and down along the entire length of the cavity. With the help of negative pressure airflow, the metal dust adhering to the inner wall and accumulated at the bottom can be thoroughly removed. This cleaning process takes no more than 15 seconds. Finally, slowly withdraw the suction nozzle 1 in the opposite direction of pushing in, ensuring that the steel wire smoothly detaches from the steel wire receiving groove 3. The entire process does not require machine shutdown and does not affect the continuous operation of the production line.
