Description

Technical Field

[0001] The invention relates to the technical field of steel wire production, in particular to a surface treatment device for steel wire production. Background Art

[0002] After the steel wire has undergone the heat treatment process, an oxide layer will appear on its surface. In order to ensure the quality of subsequent processing, the oxide layer on the surface needs to be removed. The current treatment method is pickling, which is a chemical rust removal method. The acid is volatile and pollutes the atmospheric environment. The emissions generated will pollute the land and water environment. The secondary treatment process of the emissions is complex and costly, which does not conform to the existing development trend of energy conservation and environmental protection.

[0003] At present, some manufacturers propose to use grinding wheel grinding to remove the oxide layer. However, when grinding with a grinding wheel, the contact between the grinding wheel and the steel wire is only one point, and the grinding effect is limited. It is difficult to ensure the grinding effect of the circumferential surface of the steel wire. In addition, during the grinding process, it is not convenient to clean up the debris generated by grinding in time. The polished steel wire also needs to be processed by cleaning equipment and drying equipment before it can be put into the next production process. The whole process is cumbersome and the production efficiency is low.

[0004] Therefore, we propose a surface treatment device for steel wire production to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a surface treatment device for steel wire production to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A surface treatment device for steel wire production, comprising a bottom box, a fixing plate fixedly mounted on the bottom box, and a screw ring mounted on one side of the fixing plate extending toward the center of the bottom box, a screw barrel passing through the inside of the screw ring and screwed together, a steel wire passing through the inside of the screw barrel, and a grinding assembly for grinding the surface of the steel wire mounted on the end of the screw barrel, and when the screw barrel rotates, the grinding assembly is controlled to rotate and move along the extending direction of the steel wire for grinding;

[0008] The grinding assembly includes a pair of grinding blocks, which adopt an arc structure and are symmetrically distributed about the axis of the screw barrel. Telescopic guide rods are installed on the opposite sides of the two grinding blocks, and the end of the telescopic guide rod away from the grinding block passes through a convex plate, which is fixed to the edge of the port of the screw barrel. A telescopic part for driving the telescopic guide rod to extend and retract is fixed on the outer wall of the convex plate, and a spring is also installed between the convex plate and the grinding block.

[0009] In a further embodiment, a movable plate is rotatably installed on the periphery of one end of the screw barrel close to the grinding assembly. The movable plate is slidably connected to the bottom box through a slider, and the sliding direction of the movable plate is consistent with the axial direction of the screw barrel. A cleaning ring and a drying ring coaxial with the screw barrel are installed on the movable plate, and the cleaning ring is located between the drying ring and the grinding assembly.

[0010] In a further embodiment, a plurality of spray bars are evenly distributed along the circumference on one side of the cleaning ring close to the grinding assembly, the spray bars are connected to the inside of the cleaning ring, and the spray bars are inclined toward the axis of the cleaning ring.

[0011] In a further embodiment, the outer shape structure of the drying ring adopts a trumpet-shaped structure, the inner diameter of one end of the trumpet-shaped structure facing the cleaning ring is smaller than the inner diameter of the port at the other end, the outer shell of the drying ring adopts a hollow structure, and an annular air outlet is formed at one end of the drying ring close to the cleaning ring.

[0012] In a further embodiment, a liquid injection component for supplying liquid to the cleaning ring and an air injection component for supplying air to the drying ring are respectively installed at both ends of the base box, and the liquid injection component and the air injection component work alternately. When the screw barrel drives the grinding component forward for grinding, the liquid injection component injects liquid into the cleaning ring to spray the surface of the steel wire. When the screw barrel drives the grinding component to move backward and reset, the air injection component injects gas into the drying ring to blow away water droplets on the surface of the steel wire.

[0013] In a further embodiment, the liquid injection assembly and the gas injection assembly have the same structure, and both are composed of a hollow tube and an outer cover tube that are socketed with each other, and one end of the hollow tube extending into the outer cover tube is equipped with a piston block through a one-way valve, and a circular hole is opened inside the piston block, and a one-way valve 2 is installed at the inlet at the rear end of the outer cover tube.

[0014] In a further embodiment, a liquid inlet pipe is installed at the outer end of the one-way valve 2 in the liquid injection assembly, and the liquid inlet pipe is connected to the inside of the bottom box, and a filter screen for filtering oxide scale and impurities is installed inside the bottom box.

[0015] In a further embodiment, a gear ring is fixed to one end of the screw barrel away from the grinding assembly, the outer edge of the gear ring is meshed with a driving gear, and a movable frame is rotatably installed on both sides of the gear ring and the driving gear, the movable frame is slidably connected to the bottom box, and a servo motor that drives the driving gear to rotate is installed on the outer wall of the movable frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention arranges the grinding component to contact the surface of the steel wire, and then rotates the screw barrel, which can drive the grinding component to rotate and grind along the circumference of the steel wire surface to remove the oxide layer. Under the thread limiting action of the screw ring, the screw barrel can rotate and move along the axis at the same time, thereby controlling the grinding component to rotate and move along the extension direction of the steel wire for grinding, effectively improving the grinding effect.

[0018] The present invention arranges the screw barrel to drive the liquid injection assembly to inject liquid into the cleaning ring when it moves along the extension direction of the steel wire, so that when the grinding assembly is grinding, the cleaning ring can spray liquid toward the grinding position, which not only facilitates the flushing of debris generated by grinding, but also helps to cool the grinding assembly, thereby ensuring the working effect of the grinding.

[0019] The present invention arranges the screw barrel so that it can drive the gas injection assembly to inject gas into the drying ring when it moves, so as to spray gas into the grinding area, blow away the water droplets remaining on the surface of the steel wire, and then reduce the moisture content on the surface of the steel wire, perform pre-drying, and make the drying efficiency higher when the steel wire enters the next drying process for processing.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0030] See also Figure 1-2 A surface treatment device for steel wire production comprises a base box 1, on which a fixing plate 2 is fixedly mounted, and a spiral ring 3 is mounted on one side of the fixing plate 2 extending toward the center of the base box 1, a screw barrel 4 is penetrated inside the screw ring 3, the axial direction of the screw barrel 4 is parallel to the length direction of the base box 1, the screw barrel 4 and the spiral ring 3 are threadedly connected, a grinding assembly 5 for grinding the surface of the steel wire is mounted at the end of the screw barrel 4, the grinding assembly 5 comprises a pair of grinding blocks 54, the pair of grinding blocks 54 adopts an arc structure, and is symmetrically distributed about the axis line of the screw barrel 4, when grinding, the steel wire penetrates the inside of the screw barrel 4, the grinding blocks 54 contact the surface of the steel wire, when the screw barrel 4 rotates, it can move along the axial direction of the steel wire while rotating by utilizing the thread effect between itself and the spiral ring 3, thereby controlling the grinding assembly 5 to rotate and move together, thereby realizing rotary moving grinding along the axial direction of the steel wire, and achieving better grinding effect.

[0031] See also Figure 2, considering that in actual use, the grinding block 54 will wear out when rubbing against the surface of the steel wire. Therefore, after long-term use, as the grinding block 54 wears out, the grinding block 54 gradually cannot be close to the surface of the steel wire, thereby affecting the grinding effect. Therefore, telescopic guide rods 52 are installed on the opposite sides of the two grinding blocks 54, and the end of the telescopic guide rod 52 away from the grinding block 54 passes through the convex plate 51, which is fixed to the edge of the port of the screw barrel 4. A telescopic member 55 for driving the telescopic guide rod 52 to extend and retract is fixed on the outer wall of the convex plate 51. The telescopic member 55 can adopt an electric push rod to control the distance between the grinding block 54 and the steel wire by extension, so that the two are in a close contact state, thereby ensuring the grinding effect. A spring 53 is also installed between the convex plate 51 and the grinding block 54 to improve the stability of the grinding block 54 during telescopic movement.

[0032] See also Figure 3-4 , considering that the oxide layer debris generated by grinding needs to be processed in time to prevent it from being stuck between the grinding block 54 and the surface of the steel wire and affecting the grinding effect, a movable plate 6 is rotatably installed on the outer periphery of the screw barrel 4 close to the grinding assembly 5, and the movable plate 6 is slidably connected to the bottom box 1 through a slider 61, so that when the screw barrel 4 rotates and moves, it only drives the movable plate 6 to move, and does not drive the movable plate 6 to rotate. The sliding direction of the movable plate 6 is consistent with the axial direction of the screw barrel 4. A cleaning ring 7 and a drying ring 9 coaxial with the screw barrel 4 are installed on the movable plate 6, so that the cleaning ring 7 and the drying ring 9 can move together with the movable plate 6, wherein the cleaning ring 7 is between the drying ring 9 and the grinding assembly 5, and the cleaning ring 7 is used to flush the grinding position, which can not only flush away the debris, but also cool the grinding block 54 to ensure its good working effect, and the drying ring 9 can pre-dry the surface of the flushed steel wire, which is convenient for the steel wire to save drying time when it enters the drying process later.

[0033] See also Figure 5 Furthermore, in order to improve the flushing effect, a plurality of spray rods 71 ​​are evenly distributed along the circumferential direction on one side of the cleaning ring 7 close to the grinding assembly 5. The spray rods 71 ​​are connected to the inside of the cleaning ring 7, and the spray rods 71 ​​are inclined toward the axis of the cleaning ring 7, so that the spray port of the spray rod 71 is aligned with the grinding position of the grinding assembly 5. Multiple spray rods 71 ​​spray toward the circumferential surface of the steel wire at the same time, and the flushing efficiency is improved.

[0034] See also Figure 6 Furthermore, in order to improve the pre-drying effect, the external structure of the drying ring 9 adopts a trumpet-shaped structure, the inner diameter of one end of the trumpet-shaped structure facing the cleaning ring 7 is smaller than the inner diameter of the port at the other end, the outer shell of the drying ring 9 adopts a hollow structure, and an annular air outlet is formed at one end of the drying ring 9 close to the cleaning ring 7, the annular air outlet is aligned with the polished area of ​​the steel wire surface, and the airflow blown out from the annular air outlet of the drying ring 9 can effectively remove the water droplets remaining on the surface of the steel wire.

[0035] See also Figure 3-6 In order to facilitate the operation of the cleaning ring 7 and the drying ring 9, a liquid injection assembly 8 for infusing liquid into the cleaning ring 7 and a gas injection assembly 10 for infusing gas into the drying ring 9 are respectively installed at both ends of the bottom box 1, and the liquid injection assembly 8 and the gas injection assembly 10 work alternately. The liquid injection assembly 8 and the gas injection assembly 10 have the same structure, and the liquid injection assembly 8 and the gas injection assembly 10 are composed of a hollow tube 11 and an outer cover tube 12 which are connected to each other. A piston block 13 is installed at one end of the hollow tube 11 extending into the outer cover tube 12 through a one-way valve 14, and a circular hole is opened inside the piston block 13. A one-way valve 2 15 is installed at the inlet of the tail end of the outer cover tube 12. When the screw barrel 4 drives the grinding assembly 5 forward for grinding, the piston block 13 in the gas injection assembly 10 is first pulled forward, and then the outer cover tube in the gas injection assembly 10 is moved forward through the one-way valve 2 15. 12 is inflated, and at the same time, the piston block 13 in the liquid injection component 8 is driven to move forward, thereby compressing the liquid in the outer cover tube 12 in the liquid injection component 8, so that the liquid is transported to the cleaning ring 7 through the inside of the piston block 13, the one-way valve 14 and the hollow tube 11, and the liquid is injected into the cleaning ring 7 to spray the surface of the steel wire. On the contrary, when the screw barrel 4 drives the grinding component 5 to move back and reset, the piston block 13 in the liquid injection component 8 moves backward, and then the outer cover tube 12 in the liquid injection component 8 is filled with liquid through the one-way valve 15, and at the same time, the piston block 13 in the gas injection component 10 is driven to move backward, thereby compressing the gas in the outer cover tube 12 in the gas injection component 10, so that the gas is transported to the drying ring 9 through the inside of the piston block 13, the one-way valve 14 and the hollow tube 11, and the drying ring 9 sprays air to blow away the water droplets on the surface of the steel wire.

[0036] See also Figure 2-4 Considering that the water after flushing will be collected by the bottom box 1, in order to further reduce resource consumption, a liquid inlet pipe 16 is installed at the outer end of the one-way valve 15 in the injection assembly 8, and the liquid inlet pipe 16 is connected to the inside of the bottom box 1 to facilitate the recovery of the water in the bottom box 1 for secondary flushing. By installing a filter screen 17 for filtering oxide scale and impurities inside the bottom box 1, the oxide scale and impurities can be prevented from mixing in the recovered water.

[0037] See also Figure 2-4 In order to facilitate the driving of the screw barrel 4 to rotate, a gear ring 41 is fixed to one end of the screw barrel 4 away from the grinding assembly 5, and the outer edge of the gear ring 41 is meshed with a driving gear 44, and a movable frame 42 is rotatably installed on both sides of the gear ring 41 and the driving gear 44, and the bottom of the movable frame 42 is fixed on the slider 61, so that the movable frame 42 slides relative to the bottom box 1, and a servo motor 43 is installed on the outer wall of the movable frame 42, and then the servo motor 43 is used to drive the driving gear 44 to rotate, and then the meshing action between the servo motor 43 and the gear ring 41 is used to drive the screw barrel 4 to rotate.

[0038] Working principle: the steel wire to be treated passes through the screw barrel 4, the grinding component 5, the cleaning ring 7 and the drying ring 9. Under the action of the external traction equipment, the steel wire first moves a short distance in the device and then stops. Then the device is started for surface treatment. The screw barrel 4 first drives the grinding component 5 to rotate and move in the direction of the liquid injection component 8 for grinding. At this time, the screw barrel 4 compresses the liquid injection component 8, so that the cleaning ring 7 sprays liquid to flush the grinding area. At the same time, the screw barrel 4 pulls the gas injection component 10 for inflation. After grinding the section of steel wire, the screw barrel 4 drives the grinding component 5 to retreat. At the same time, the grinding component 5 does not contact the steel wire during the retreat process. At this time, the screw barrel 4 compresses the gas injection component 10, so that the drying ring 9 blows air to pre-dry the polished steel wire section. At the same time, the screw barrel 4 pulls the liquid injection component 8 to replenish the liquid. When the screw barrel 4 retreats to the initial position, the surface treatment operation of the section of steel wire is completed, and then the steel wire moves forward for a distance, and the above operation is repeated for grinding.
