Description

Technical Field

[0001] The invention relates to the technical field of stainless steel wires, in particular to a stainless steel wire which is easy to bend and a production process thereof. Background Art

[0002] Stainless steel wire, also known as stainless steel wire, is a kind of silk product with various specifications and models made of stainless steel as raw material. Common stainless steel wires with good corrosion resistance and high cost performance are 304 and 316 stainless steel wires. Stainless steel wire drawing is a metal plastic processing process in which the wire rod or wire blank is pulled out from the die hole of the wire drawing die under the action of the wire drawing machine to produce small-section steel wire or non-ferrous metal wire. Wires of different cross-sectional shapes and sizes of various metals and alloys can be produced by drawing. The drawn wire has precise size and smooth surface, and the drawing equipment and molds used are simple and easy to manufacture.

[0003] The existing stainless steel wire that is easy to bend and its production process only use grooving to achieve the purpose of easy bending. However, the shear resistance of the steel wire decreases after multiple bending, so it is easy to break. Or the steel wire is too hard to be easy to bend, so the toughness and strength of the steel wire cannot be well coordinated, and the use effect is poor. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a stainless steel wire that is easy to bend and a production process thereof, which solves the problem that the purpose of convenient bending can be achieved only by cutting grooves, but the shear resistance of the steel wire decreases after multiple bending, so that it is easy to break, or the steel wire is too hard to be easy to bend and use, so that the toughness and strength of the steel wire cannot be well coordinated, resulting in poor use effect.

[0005] (II) Technical solution To achieve the above purpose, the present invention is implemented through the following technical scheme: a stainless steel wire that is easy to bend, comprising a steel core, a tough layer is arranged on the outside of the steel core, a reinforcing layer is arranged on the outside of the tough layer, a steel pipe is sleeved on the outside of the reinforcing layer, a ring groove is opened on the surface of the steel pipe, a plurality of the ring grooves are arranged, a leather sleeve is sleeved on the outside of the steel pipe, fixing parts are arranged at both ends of the steel pipe, a protrusion is fixedly connected to the inner wall of the fixing part, a receiving groove is opened at both ends of the steel pipe, the fixing part is clamped in the inside of the receiving groove, a groove is opened in the inside of the receiving groove, and the protrusion is clamped in the inner wall of the groove. The reinforcement layer includes reinforcement wires, the number of which is set to be multiple, and the multiple reinforcement wires are spirally twisted inside the steel pipe. A connecting block is fixedly connected to one side of the reinforcement wire, and a connecting groove is opened on the other side of the reinforcement wire. The connecting block is clamped into the inside of the connecting groove of the adjacent reinforcement wire. The toughness layer can enhance the overall toughness of the steel wire and reduce the possibility of steel wire breakage. The reinforcement layer can enhance the overall compressive strength of the stainless steel wire and improve the overall strength of the steel wire. The fixing parts can be used to close the two ends of the stainless steel wire to prevent the original parts inside the steel wire from being forked and exposed, resulting in reduced quality of the steel wire.

[0006] Preferably, the toughness layer includes an outer protective layer, the outer protective layer is sleeved on the inside of the reinforcing wire, the inner protective layer is sleeved on the inside of the outer protective layer, and a composite wire is arranged between the inner protective layer and the outer protective layer. The position of the composite wire can be relatively fixed by the outer protective layer and the inner protective layer to prevent the position of the composite wire from changing, thereby ensuring the uniformity of the overall material distribution of the steel wire and ensuring the stability of the overall performance of the steel wire.

[0007] Preferably, the composite wire includes a metal wire group, the outer surface of which is coated with an adhesive. The metal wire group can strengthen the bearing tension of the stainless steel wire, and the metal wire group can be firmly bonded by the adhesive of phenolic glue to prevent separation between the metal wire groups or explosion of the ends, thereby improving the integrity of the metal wire group.

[0008] Preferably, an anti-corrosion filler is filled between the outer protective layer and the inner protective layer. The provision of the anti-corrosion filler can create a gap between the outer protective layer and the inner protective layer, so that the composite wire is more tightly connected between the outer protective layer and the inner protective layer. The provision of the anti-corrosion filler can increase the overall anti-corrosion performance of the steel wire and prevent internal rust, thereby extending the service life of the steel wire.

[0009] Preferably, the reinforcing wire and the composite wire are both in a spirally coiled shape. The spirally coiled reinforcing wire and the composite wire can effectively disperse the force, so that the steel wire is not easy to break when subjected to force, thereby enhancing the shear resistance of the steel wire when it is repeatedly bent.

[0010] A production process for stainless steel wire that is easy to bend, comprising the following steps: S1. First, a wire rod is selected, and then an oxide layer on the surface of the wire rod is removed by an alkaline solution, and finally the wire rod with the oxide layer removed is cleaned and dried to obtain a treated wire rod, and the treated wire rod is subjected to wire drawing by a wire drawing machine to obtain a steel core; S2, selecting two blanks of different diameters and subjecting them to multiple cold drawing to obtain outer protective layers and inner protective layers of two different diameters; S3, selecting a plurality of aluminum wires and bonding them with an adhesive to form a metal wire group, then twisting the plurality of metal wire groups into a spirally wound shape through a stranding machine to obtain a composite wire, and sleeve the composite wire between the outer protective layer and the inner protective layer to form a toughness layer; S4, selecting steel wire raw materials and drawing them through a wire drawing machine for multiple times to form reinforcing wires with connecting blocks and connecting grooves, clamping a plurality of the reinforcing wires into a ring shape, and then twisting them into a spiral shape through a stranding machine, thereby obtaining a reinforcing layer; S5, the rough tube blank after the treatment is selected and subjected to multiple cold drawing to obtain a steel tube; S6, sleeve the toughness layer on the outside of the steel core, then sleeve the reinforcement layer on the outside of the toughness layer, and then sleeve the steel pipe on the outside of the reinforcement layer, and perform wire drawing on the sleeved whole parts through a wire drawing machine to obtain preliminary stainless steel wire; S7, engraving the surface of the steel pipe by a laser engraving machine so that an annular groove, a convex block and a receiving groove are formed on the surface of the steel pipe, a fixing piece is obtained by a die-casting process, and the fixing piece is snap-fitted to the annular grooves at both ends of the steel pipe, and the convex block is clamped inside the groove; S8. The surface of the stainless steel wire with the fixed part is covered with a leather cover by a covering machine to obtain a final stainless steel wire product.

[0011] Preferably, in step S2, the wall thickness of the outer protective layer is slightly larger than the wall thickness of the inner protective layer, so that the wall thickness of the outer protective layer after subsequent wire drawing is closer to that of the inner protective layer, and the wall thickness of the outer protective layer after subsequent drawing is not much different from that of the inner protective layer, thereby achieving the same protective effect on the metal wire group and avoiding the outer protective layer being too thin and having a poor protective effect during drawing.

[0012] Preferably, in step S2, the surfaces of the outer protective layer and the inner protective layer are coated with a waterproof material, and the waterproof material is coated after the outer protective layer and the inner protective layer are drawn and formed. The waterproof material can prevent moisture from affecting the adhesive on the surface of the metal wire group, and can also effectively prevent moisture from invading the interior of the steel wire to corrode it, thereby extending the service life of the steel wire.

[0013] Preferably, in step S3, the surface of the aluminum wire is ground by a sandblasting machine to make the surface of the aluminum wire rough, thereby making it easy for adhesive to adhere. The surface of the aluminum wire ground by the sandblasting machine is rougher, so that the adhesive can firmly bond the metal wires into a metal wire group.

[0014] (III) Beneficial effects The present invention provides a stainless steel wire that is easy to bend and a production process thereof. It has the following beneficial effects: (I) The stainless steel wire that is easy to bend and its production process can increase the overall toughness of the steel wire by using the toughness layer, reduce the easy breakage of the steel wire when it is bent, and increase the overall strength of the steel wire by using the reinforcement layer, thereby extending the life of the steel wire when it is bent. Through the dual arrangement of the toughness layer and the reinforcement layer, the steel wire can be repeatedly bent while ensuring the strength of the steel wire, that is, the toughness of the steel wire is retained and the overall performance of the steel wire is enhanced.

[0015] (ii) The stainless steel wire that is easy to bend and its production process can reduce the possibility of a single reinforcing wire breaking by setting a plurality of reinforcing wires, and can form a close connection between adjacent reinforcing wires through the connecting blocks and the connecting grooves. The reinforcing wires are connected by the connecting blocks and the connecting grooves, which reduces the risk of wire leakage and improves the overall performance of the reinforcing wires.

[0016] (III) The bendable stainless steel wire and its production process can effectively disperse external force by arranging the reinforcing layer and the toughness layer into a spiral winding shape, so that the steel wire is not easy to break when subjected to pressure or tension. This force dispersion characteristic makes the spirally wound steel wire have higher strength and toughness, and can produce a certain buffering effect, thereby maintaining the stability of the structure.

[0017] (iv) The stainless steel wire that is easy to bend and its production process can close both ends of the steel wire through fixing parts. The design of the closed cross-section can effectively prevent the intrusion of external air, moisture and other substances, thereby avoiding rust and damage inside the steel wire and extending the service life of the steel wire.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-9The present invention provides a technical solution: a stainless steel wire that is easy to bend, comprising a steel core 1, a toughness layer 2 is arranged on the outside of the steel core 1, a reinforcement layer 3 is arranged on the outside of the toughness layer 2, a steel tube 4 is sleeved on the outside of the reinforcement layer 3, an annular groove 5 is opened on the surface of the steel tube 4, and a plurality of annular grooves 5 are arranged. The steel core 1, the toughness layer 2 and the reinforcement layer 3 can be locked by the arrangement of the steel tube 4 to prevent them from being loose, thereby improving the integrity of the stainless steel wire, and the steel tube 4 can further strengthen the stainless steel wire, and the arrangement of the annular groove 5 can facilitate the bending of the stainless steel wire, and reduce the plastic deformation and bulge of the squeezed part of the stainless steel wire, thereby improving the overall aesthetics of the stainless steel wire, and after multiple bendings and plastic deformation, the internal stress of the stainless steel wire changes, which may cause the steel wire to break, and the annular groove 5 can reduce the possibility of plastic deformation of the steel wire, thereby reducing the risk of the steel wire breaking during repeated bending, and the outer sleeve of the steel tube 4 is provided with a leather sleeve 6, and the arrangement of the leather sleeve 6 can reduce the contact between the steel wire and the air The contact area between the two ends of the steel pipe 4 is increased, thereby reducing the possibility of oxidation on the surface of the steel wire, and the leather cover 6 can reduce the wear of the surface of the steel wire and improve the aesthetics. Fixing members 7 are provided at both ends of the steel pipe 4, and the inner wall of the fixing member 7 is fixedly connected with a protrusion 8. Receiving grooves 9 are provided at both ends of the steel pipe 4. The fixing member 7 is clamped in the interior of the receiving groove 9, and a groove 10 is provided in the interior of the receiving groove 9. The protrusion 8 is clamped in the interior of the groove 10. The reinforcing layer 3 includes reinforcing wires 31. The number of reinforcing wires 31 is set to multiple. Multiple reinforcing wires 31 are spirally wrapped and twisted in the interior of the steel pipe 4. A connecting block 32 is fixedly connected to one side of the reinforcing wire 31, and a connecting groove 33 is provided on the other side of the reinforcing wire 31. The connecting block 32 is clamped in the interior of the connecting groove 33 of the adjacent reinforcing wire 31. The toughness layer 2 can enhance the overall toughness of the steel wire and reduce the possibility of steel wire breakage. The reinforcing layer 3 can enhance the overall compressive strength of the stainless steel wire and improve the overall strength of the steel wire. The fixing member 7 can be used to seal the two ends of the stainless steel wire to prevent the original fork inside the steel wire from being exposed, resulting in reduced quality of the steel wire.

[0022] Among them, the toughness layer 2 includes an outer protective layer 21, the outer protective layer 21 is sleeved inside the reinforcing wire 31, the inner protective layer 22 is sleeved inside the outer protective layer 21, and a composite wire 23 is arranged between the inner protective layer 22 and the outer protective layer 21. The position of the composite wire 23 can be relatively fixed by the outer protective layer 21 and the inner protective layer 22 to prevent the position of the composite wire 23 from changing, thereby ensuring the uniformity of the overall material distribution of the steel wire and ensuring the stability of the overall performance of the steel wire.

[0023] Among them, the composite wire 23 includes a metal wire group 231, the outer surface of the metal wire group 231 is coated with an adhesive 232. The metal wire group 231 can strengthen the bearing tension of the stainless steel wire, and the adhesive 232 of phenolic glue can firmly bond the metal wire group 231 to prevent separation between the metal wire groups 231 or explosion of the ends, thereby improving the integrity of the metal wire group 231.

[0024] Among them, anti-corrosion filler is filled between the outer protective layer 21 and the inner protective layer 22. The setting of the anti-corrosion filler can create a gap between the outer protective layer 21 and the inner protective layer 22, so that the composite wire 23 is more tightly connected between the outer protective layer 21 and the inner protective layer 22. The setting of the anti-corrosion filler can increase the overall anti-corrosion performance of the steel wire and prevent its internal corrosion, thereby extending the service life of the steel wire. When the device is used for industrial production or infrastructure, while ensuring the connection strength, the corrosion resistance of the steel wire is increased to improve the use effect. The anti-corrosion filler can be an epoxy resin anti-corrosion filler or a zinc-rich resin anti-corrosion filler, etc.

[0025] Among them, the reinforcing wire 31 and the composite wire 23 are both spirally coiled, making the reinforcing wire 31 and the composite wire 23 spirally coiled, the structure is more compact and stable, and more reliable when used. The spirally coiled reinforcing wire 31 and the composite wire 23 can effectively disperse the force, making the steel wire not easy to break when subjected to force, thereby enhancing the shear resistance when the steel wire is repeatedly bent.

[0026] A production process for stainless steel wire that is easy to bend, comprising the following steps: S1. First, a wire rod is selected, and then the oxide layer on the surface of the wire rod is removed by an alkaline solution. Finally, the wire rod with the oxide layer removed is cleaned and dried to obtain the treated wire rod, and the treated wire rod is drawn by a wire drawing machine to obtain a steel core 1. When selecting, a disc with a suitable diameter is selected according to the needs, and at the same time, a steel wire blank with a diameter that is too large is avoided. In the later drawing process, a lot of time is required for drawing the blank, which reduces the production efficiency of the stainless steel wire. Then, the oxide layer on the surface of the wire rod is removed by an alkaline solution. The stainless steel wire is soaked in a potassium permanganate alkaline solution, that is, potassium permanganate is added to a strong alkaline sodium hydroxide or potassium hydroxide solution. After soaking for a period of time, the purpose of loosening and removing the oxide scale on the surface of the stainless steel wire is achieved. Then, the wire rod is taken out, and finally the oxide layer is removed. The wire rod with the oxide layer is cleaned and dried. After being treated with an alkaline solution, some alkaline substances or oxide residues may remain on the surface of the stainless steel wire. Therefore, subsequent cleaning treatment is required. When cleaning the wire rod with the oxide layer removed, the wire rod is placed in clean water and swung and oscillated to completely remove the residue on the surface of the wire rod and restore the surface finish of the steel wire. The moisture on the surface of the wire rod is then dried by a dryer to obtain the treated wire rod. The treated wire rod is then repeatedly drawn by a wire drawing machine to obtain a steel core 1. The steel core 1 after drawing is subjected to a low-temperature tempering treatment to eliminate the internal stress of the steel core 1. Specifically, the steel core 1 is heated to a relatively low temperature, not exceeding 500°C, maintained for a period of time, and then slowly cooled. This can eliminate the internal stress generated by the steel core 1 during the cold drawing process and improve the physical and mechanical properties of the steel core 1. S2, select two rough tube blanks of different diameters and respectively undergo multiple cold drawing to obtain two outer protective layers 21 and inner protective layers 22 of different diameters. Similarly, select two suitable rough tube blanks of different sizes and treat them with alkaline solution to remove the oxides on the surface of the rough tube blanks, and then wash away the alkaline solution remaining on the surface with clean water, and finally dry the rough tube blanks with a drying device to obtain the treated rough tube blanks, and then use a wire drawing machine to continuously draw the rough tube blanks until the rough tube blanks reach the required wall thickness, and obtain two outer protective layers 21 and inner protective layers 22 of two different diameters; S3, select multiple aluminum wires and bond them with adhesive 232 to form a metal wire group 231, then use a stranding machine to twist the multiple metal wire groups 231 into a spiral winding shape to obtain a composite wire 23, and put the composite wire 23 between the outer protective layer 21 and the inner protective layer 22 to form a toughness layer 2, select an aluminum wire coil, and then soak it in an alkaline solution, take it out after soaking for a period of time, and then rinse the alkaline solution remaining on its surface with clean water, and then dry it through a drying device, and then straighten the treated aluminum wire coil through a straightening machine and cut it into small sections of the same length, and then bond seven aluminum wires in a group together through an adhesive 232 to obtain a metal wire group 231, and then make multiple groups of metal wire groups 231, twist multiple metal wire groups 231 into a spiral winding shape through a stranding machine to obtain a composite wire 23, and then put the composite wire 23 between the outer protective layer 21 and the inner protective layer 22; S4, select steel wire raw material and draw it through a wire drawing machine for multiple times to form a reinforcing wire 31 with a connecting block 32 and a connecting groove 33, connect multiple reinforcing wires 31 to form a ring, and then twist it into a spiral shape through a stranding machine to obtain a reinforcing layer 3. Similarly, select steel wire raw material and perform alkali washing, rinsing and drying treatments on it, and then draw it through a wire drawing machine with a mold with a connecting block 32 and a connecting groove 33 to obtain a reinforcing wire 31, and then connect multiple reinforcing wires 31 in sequence so that adjacent reinforcing wires 31 are connected to each other to form a ring-shaped reinforcing layer 3, and then twist the reinforcing layer 3 into a spiral reinforcing layer 3 through a stranding machine. The spirally arranged reinforcing layer 3 can enhance the overall strength of the steel wire, and the arrangement of the connecting groove 33 and the connecting block 32 can reduce the cracking between the reinforcing wires 31, thereby improving the stability between the reinforcing wires 31, and the arrangement of multiple reinforcing wires 31 can reduce the possibility of the reinforcing wire 31 breaking, thereby improving the service life of the steel wire; S5, the rough tube blank after the treatment is selected to be cold drawn multiple times to obtain a steel tube 4, the rough tube blank after the alkaline solution treatment is selected to be cold drawn multiple times to obtain a steel tube 4, and the steel tube 4 is subjected to low-temperature tempering treatment to eliminate the internal stress of the steel tube 4 and improve the performance of the steel tube 4; S6, sleeve the toughness layer 2 on the outside of the steel core 1, then sleeve the reinforcement layer 3 on the outside of the toughness layer 2, and then sleeve the steel tube 4 on the outside of the reinforcement layer 3, and use a wire drawing machine to draw the entire sleeved component to obtain preliminary stainless steel wire, align the middle of the toughness layer 2 with the steel core 1, and then sleeve it, similarly sleeve the reinforcement layer 3 on the outside of the toughness layer 2, and sleeve the steel tube 4 on the outside of the reinforcement layer 3, and then use a wire drawing machine to draw the entire component, so that the entire component can be drawn thinner and tighter, and obtain preliminary stainless steel wire; S7, engrave the surface of the steel pipe 4 by a laser engraving machine, so that an annular groove 5, a protrusion 8 and a receiving groove 9 are formed on the surface of the steel pipe 4, and a fixing piece 7 is obtained by a die-casting process, and the fixing piece 7 is snap-fitted on the annular groove 5 at both ends of the steel pipe 4, and the protrusion 8 is stuck in the inside of the groove 10, and the steel wire is initially obtained, and the steel pipe 4 on its surface is grooved. When grooving, the steel wire is fixed by a fixing clamp, and then the surface of the steel pipe 4 is engraved by a laser engraving machine to form an annular groove 5 and a receiving groove 9, and then the die-cast fixing piece 7 is stuck on both ends of the steel wire, and the protrusion 8 is stuck in the inside of the groove 10, so that the fixing piece 7 is fixed more tightly and not easy to fall off. The setting of the fixing piece 7 can make it difficult for the two ends of the steel wire to leak wire, thereby extending the service life of the steel wire; S8. The surface of the stainless steel wire with the fixed part 7 is covered with a leather cover 6 by a covering machine to obtain a final stainless steel wire product. The surface of the steel wire after the engraved ring groove 5 is cleaned by a cleaning brush, and then the surface is wiped with a dry cloth to prevent dust, impurities and moisture from remaining on the surface. Then, it is placed on a clean platform or in a clean environment. The covering machine is started to feed the steel wire into the equipment. The leather cover 6 is tightly attached to the surface of the steel wire through the action of the conveying wheel and the pressure wheel. During the covering process, the pressure and position of the pressure wheel are adjusted as needed to ensure that the leather cover 6 can be evenly covered on the steel wire. After the covering is completed, the steel wire is fed into a curing device, and the glue is cured by heating or natural cooling to form a strong bond. The leather cover 6 adopts a rubber leather cover 6, which makes the steel wire more elastic when bent and not easy to break.

[0027] Among them, in step S2, the wall thickness of the outer protective layer 21 is slightly larger than the wall thickness of the inner protective layer 22, so that the wall thickness of the outer protective layer 21 and the inner protective layer 22 after subsequent wire drawing are closer. During the drawing process, the material farther away from the center of the circle is easy to be drawn and thinned. Therefore, by setting the outer protective layer 21 to be slightly thicker than the inner protective layer 22, the wall thickness between the outer protective layer 21 and the inner protective layer 22 after subsequent drawing is not much different, thereby having the same protective effect on the metal wire group 231, avoiding the outer protective layer 21 being too thin and the protective effect being poor during drawing.

[0028] Among them, in step S2, the surfaces of the outer protective layer 21 and the inner protective layer 22 are coated with waterproof material, and the waterproof material is coated after the outer protective layer 21 and the inner protective layer 22 are drawn and formed. The waterproof material can prevent moisture from affecting the adhesive 232 on the surface of the metal wire group 231, and can also effectively prevent moisture from invading the interior of the steel wire to corrode it, thereby extending the service life of the steel wire.

[0029] Among them, in step S3, the surface of the aluminum wire is polished by a sandblasting machine to make the surface of the aluminum wire rough, so that it is easy to adhere to the adhesive 232. The surface of the aluminum wire polished by the sandblasting machine is rougher, so that the adhesive 232 can firmly bond the metal wires into a metal wire group 231.
