Description

Technical Field

[0001] This utility model relates to the field of metal wire drawing equipment technology, specifically a wire drawing guide wheel. Background Technology

[0002] As a core component of wire drawing machines, the development of guide wheels is closely related to the advancement of metal processing technology. Early wire drawing machines mainly used wooden or ordinary steel guide wheels, which had simple structures and limited functions, only able to perform basic wire guiding. With the increasing demands for precision and surface quality in industrial production, guide wheels have gradually developed towards specialization and high performance.

[0003] Regarding the aforementioned technologies, the applicant believes that during the operation of the wire drawing machine, the guide wheel guides and constrains the metal wire through the guide grooves on its surface to achieve stable wire transport. When the guide wheel is operating at high speed, high-frequency sliding friction occurs between the metal wire and the coating surface of the guide groove. Under continuous load, wear and failure pits gradually form on the coating surface, which can cause the metal wire to become embedded in the pits and become stuck, resulting in quality problems such as tension fluctuations and surface scratches during transmission. Utility Model Content

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1 to 4This embodiment provides a technical solution: a wire guide wheel, including a wire guide wheel body 2 and a protective mechanism 1. The protective mechanism 1 is disposed on the outside of the wire guide wheel body 2. The protective mechanism 1 includes a main mounting groove 105 uniformly opened in the middle part of the outside of the wire guide wheel body 2. A first magnet block 107 is disposed at the bottom of the inside of the main mounting groove 105. Side mounting grooves 102 are uniformly opened at both ends of the outside of the wire guide wheel body 2. A second magnet block 103 is disposed at the bottom of the inside of the side mounting groove 102. A protective sleeve 101 is disposed on the outside of the wire guide wheel body 2. The protective sleeve 101 is made of ultra-high molecular weight polyethylene, which has low density, small centrifugal force when rotating at high speed, good dynamic balance, and can resist acid and alkali corrosion. It is suitable for humid or corrosive environments, thus facilitating effective protection of the outer surface of the wire guide wheel body 2. By physically isolating the metal wire from direct contact with the wheel body, surface wear caused by high-speed friction is significantly reduced.

[0031] The protective sleeve 101 has a first mounting block 106 evenly arranged in the middle part of its inner surface, and a second mounting block 104 evenly arranged at both ends of its inner surface. The side mounting groove 102 and the main mounting groove 105 are both set in multiple groups. The side mounting groove 102 is symmetrically distributed about the main mounting groove 105, which can facilitate the fixing of the protective sleeve 101 and improve the stability of the protective sleeve 101 during operation. The second magnet block 103 is magnetically connected to the second mounting block 104, and the first magnet block 107 is magnetically connected to the first mounting block 106. The main mounting groove 105 and the side mounting groove 102 are both circular. The first mounting block 106 and the second mounting block 104 are respectively inserted into the main mounting groove 105 and the side mounting groove 102.

[0032] The overall effect of Embodiment 1 is as follows: By embedding Mounting Block 106 and Mounting Block 104 into the main mounting groove 105 and the side mounting groove 102 respectively, the protective sleeve 101 can be conveniently fixed to the outside of the guide wheel body 2 through the magnetic adsorption effect of Mounting Block 107 and Mounting Block 103 inside the main mounting groove 105 and the side mounting groove 102 with Mounting Block 106 and Mounting Block 104. The protective sleeve 101 can effectively protect the outer surface of the guide wheel body 2, and by physically isolating the metal wire from direct contact with the wheel body, it significantly reduces surface wear caused by high-speed friction, avoids the problem of decreased accuracy caused by metal wire scratches and corrosion of the wheel body, and thus extends the service life of the guide wheel body 2. When the protective sleeve 101 is damaged, it can be easily removed and replaced by taking Mounting Block 106 and Mounting Block 104 out of the main mounting groove 105 and the side mounting groove 102, thus improving the practicality of the equipment.

[0033] Example 2

[0034] The inner side of the guide wheel body 2 is provided with an aluminum alloy inner ring 202, which can improve the strength of the guide wheel body 2. The inner diameter of the aluminum alloy inner ring 202 is set to Ø19mm and the outer diameter is set to Ø20mm. The aluminum alloy inner ring 202 has a fixing groove 3 inside, which can facilitate the fixing of the guide wheel body 2, thereby improving the stability of the guide wheel body 2 during operation. The outer side of the aluminum alloy inner ring 202 is provided with an elastic base layer 201. The elastic base layer 201 is made of thermoplastic polyurethane elastomer and carbon fiber. It is obtained by step-by-step polymerization reaction of polyol, isocyanate and chain extender. The molecular chain contains both hard segments (crystalline regions formed by isocyanate and chain extender) and soft segments (amorphous regions formed by polyol), which gives it high elasticity, high strength, wear resistance and aging resistance. The elastic base layer 201 is made of thermoplastic polyurethane elastomer and carbon fiber. The above elastic base layer 201 is the prior art and will not be described in detail below.

[0035] The outer side of the elastic base layer 201 is set as a wear-resistant layer 203, which is a polyurethane layer. With its unique molecular chain structure and designability, it plays a key role in high-speed friction, impact wear and other scenarios: it absorbs the sliding energy of metal wires or the impact energy of foreign objects through the toughness of the molecular chain, reduces contact stress by combining self-lubricating properties, and inhibits material softening by using thermomechanical stability, thus significantly improving wear life.

[0036] The effect achieved by the entire second embodiment is as follows: by passing the accessory through the fixing groove 3, the guide wheel body 2 can be installed in the workplace, and the guide groove on its surface can guide and constrain the metal wire to achieve stable conveying of the metal wire.

[0037] Working principle: By embedding mounting block 106 and mounting block 104 into the main mounting groove 105 and the side mounting groove 102 respectively, the protective sleeve 101 can be easily fixed to the outside of the guide wheel body 2 through the magnetic adsorption effect of the first magnet block 107 and the second magnet block 103 inside the main mounting groove 105 and the side mounting groove 102 with the first mounting block 106 and the second mounting block 104. The protective sleeve 101 can effectively protect the outer surface of the guide wheel body 2, and by physically isolating the metal wire from direct contact with the wheel body, it significantly reduces surface wear caused by high-speed friction, avoids the problem of decreased accuracy caused by metal wire scratches and corrosion of the wheel body, and thus extends the service life of the guide wheel body 2.

[0038] Finally, if the protective sleeve 101 is damaged, the protective sleeve 101 can be easily removed and replaced by taking out the first mounting block 106 and the second mounting block 104 from the main mounting groove 105 and the side mounting groove 102, which improves the practicality of the equipment.
