Description

Technical Field

[0001] The present invention relates to the technical field of metal wire surface treatment, and particularly to a surface high-precision treatment device for metal wire processing. Background Art

[0002] Metal wire processing refers to the process of processing metal raw materials (such as steel, copper, aluminum, etc.) into linear products with specific shapes, sizes, and properties through a series of technological means. During the processing, the surface of the metal wire needs to be treated. Specifically, pre-treatments such as grinding or polishing the surface of the metal wire are required to effectively repair or eliminate the defects on the surface of the metal wire and remove rust, thereby improving the appearance quality and overall quality of the metal wire. However, the current grinding methods for metal wires mostly rely on manual operations, and this method has obvious drawbacks. On the one hand, the labor intensity is extremely high, and workers are prone to fatigue during long-term operations. On the other hand, the grinding efficiency is low, making it difficult to meet the requirements of large-scale processing and production of metal wires.

[0003] After retrieval, a Chinese patent with the publication number CN115741278B discloses a surface treatment device and treatment process for metal wire processing. This patent realizes continuous and comprehensive grinding of the outer surface of the metal wire through the rapid rotation of multiple grinding rollers on the surface of the metal wire and the conveyance of the metal wire. However, since the contact area between the grinding roller and the outer surface of the metal wire is usually relatively limited, when processing metal wires with a larger diameter, more time is often required to ensure the uniformity of grinding, thereby reducing the grinding efficiency of the metal wire. In addition, the dust generated during the grinding process of the metal wire is likely to adhere to the outer surface of the grinding roller, which not only weakens the grinding effect of the grinding roller but also may interfere with the normal grinding process of the metal wire, thereby reducing the grinding quality and having poor practicability. Summary of the Invention

[0015] Compared with the existing technology, the advantages of the present invention are as follows: 1. Through the mutual cooperation of the rotation mechanism, the regulation mechanism, and the blowing mechanism, the present invention can not only make the abrasive belt closely fit with the main body of the metal wire with a larger area before grinding the main body of the metal wire with a larger diameter by two abrasive belts, so that the number of abrasive grains participating in grinding on the abrasive belt per unit time increases, but also use the gas filled into the adjusting roller by the air pump to blow off the dust adhered to the surface of the abrasive belt due to the grinding operation, thereby reducing the negative impact of the dust adhesion on the grinding effect of the abrasive belt, and then effectively improving the grinding efficiency and grinding quality of the main body of the metal wire. In addition, through the setting of the air suction mechanism, the dust inside the rotating housing and on the outer surface of the main body of the metal wire can be sucked out by turning on the dust collector and opening the dust suction holes and dust suction grooves, thereby avoiding the escape of dust and effectively ensuring the product appearance of the main body of the metal wire after grinding.

[0016] 2. Through the mutual cooperation of the regulation mechanism and the blowing mechanism, the present invention can flexibly adjust the tension of the abrasive belt by the staggered extrusion of the pressure roller and the adjusting roller on the abrasive belt, so that it can always maintain a taut state, enabling the abrasive belt to closely fit with the main body of the metal wire with different diameters during grinding and maintaining a large contact area with the main body of the metal wire with different diameters. This can not only prevent the abrasive belt from affecting its rotation smoothness due to slackness, but also effectively ensure the grinding effect on the surface of the main body of the metal wire, that is, effectively ensure the grinding quality and efficiency of the main body of the metal wire with different diameters, and improve the wide applicability of the device.

[0017] 3. Through the mutual cooperation of the rotating mechanism and the regulating mechanism, the present invention enables the two abrasive belts to revolve around the main body of the metal wire while rotating on their own axes. The combination of this revolution and rotation enables the abrasive belts to continuously change their contact positions with the main body of the metal wire, thereby achieving comprehensive grinding of the main body of the metal wire, effectively improving the grinding quality. Meanwhile, under the action of the wire winding and unwinding device, the main body of the metal wire can continuously move to one side, thus realizing continuous grinding operation on the main body of the metal wire, and further improving the grinding efficiency of the main body of the metal wire.

[0018] 4. Through the setting of the air suction mechanism, the present invention can not only suck the dust inside the rotating housing and on the outer surface of the main body of the metal wire, but also discharge the air with a relatively high temperature generated inside the installation cavity due to the grinding of the main body of the metal wire by the abrasive belts. Thereby, while reducing the temperature inside the installation cavity, it also accelerates the air circulation inside it, and can, to a certain extent, reduce the temperature of the contact surface between the abrasive belt and the main body of the metal wire, reduce the aging speed of the abrasive belt, and effectively improve the service life of the abrasive belt.

[0019] 5. Through the setting of the spring in the pressing component, the present invention enables the pressure roller to adapt to the slight displacement of the main body of the metal wire. When the main body of the metal wire undergoes slight displacement, through the extrusion of the spring, the pressure roller can move flexibly accordingly, ensuring that under the combined action of the four pressure rollers, the pressure distribution between the main body of the metal wire and the abrasive belt remains uniform, thereby improving the uniformity of grinding the main body of the metal wire, that is, further improving the grinding quality of the main body of the metal wire.

[0027] Referring to Figures 5 to 10, a blowing mechanism is provided on the installation cavity 17 and the installation housing 22 for blowing air on the surfaces of the two abrasive belts 20. The blowing mechanism includes two lifting components 24, which are symmetric to each other and are respectively arranged on the installation housing 22 on two U-shaped sliding bars 25. Two adjusting rollers 243 are rotatably connected to each of the two lifting components 24. The lifting component 24 is used to lift and lower the adjusting roller 243. The inside of the adjusting roller 243 is hollow, and a partition piece 245 is fixedly installed through the middle position of its outer wall. The adjusting roller 243 is located on the side of the installation housing 22 away from the pressing component 23 and is located between the two abrasive belts 20. A plurality of air outlet grooves 244 are evenly formed on the adjusting roller 243, and the plurality of air outlet grooves 244 are evenly distributed on both sides of the partition piece 245. Two air supply components are symmetrically arranged in the installation cavity 17, and the two air supply components are respectively located on the side of the two lifting components 24 away from the pressing component 23, and are respectively used to convey gas into the corresponding adjusting roller 243.

[0028] Refer to Figures 6 to 10 , the two lifting components 24 have the same structure. One of the lifting components 24 includes four mounting blocks and four third electric telescopic rods 241. The four mounting blocks are symmetrically installed in pairs on one side of the two installation housings 22. Two of the third electric telescopic rods 241 are installed at the tops of the two upper mounting blocks, and the other two third electric telescopic rods 241 are installed at the bottoms of the two lower mounting blocks.

[0029] Refer to Figures 5 to 10 , the two air supply components have the same structure.

[0030] Refer to Figures 1 to 4 and Figure 11, an air suction mechanism and a limiting mechanism are provided on the processing table 1. The air suction mechanism is used to suck out the gas in the rotating housing 9, and the limiting mechanism is used to limit the metal wire body 4. The air suction mechanism includes a dust collector 5 and a support frame 10. The dust collector 5 and the support frame 10 are both detachably installed on the top of the processing table 1. A dust suction frame 11 is installed on the support frame 10. A connecting pipe is installed at the output end of the dust collector 5, and the dust collector 5 is connected to the dust suction frame 11 through the connecting pipe. One side of the dust suction frame 11 is located in the through hole on the end cover 8, and a through hole three for the metal wire body 4 to pass through is provided through the dust suction frame 11. A plurality of dust suction grooves are evenly opened in the through hole three. A plurality of dust suction holes are opened on one side of the dust suction frame 11 located in the through hole. The limiting mechanism includes two first electric telescopic rods 6. The two first electric telescopic rods 6 are both installed on the top of the processing table 1 and are respectively located on both sides of the outer box 3. A limiting ring 7 for the metal wire body 4 to pass through is detachably installed at the output ends of the two first electric telescopic rods 6. The first electric telescopic rod 6 and the limiting ring 7 are used to limit the metal wire body 4 to prevent the metal wire body 4 from shifting during movement and grinding. And since the limiting ring 7 is detachably installed at the output end of the first electric telescopic rod 6, different diameter limiting rings 7 can be replaced according to work requirements.

[0031] In the present invention, when surface treatment (i.e., surface grinding) is performed on the metal wire body 4 with a larger diameter, first, the metal wire body 4 is guided from the straightening device 2 to the outer box 3. At this time, the metal wire body 4 has passed through the limiting ring 7 between the straightening device 2 and the outer box 3. Then, the metal wire body 4 passes through the through hole two on the outer box 3 and the connecting seat 15, the connecting ring 16, the through hole one on the rotating housing 9, the through hole on the end cover 8, and the through hole three on the dust suction frame 11 in sequence, and finally passes through the limiting ring 7 corresponding to the position of the dust collector 5 and is connected to the external wire drawing and winding device (at this time, the metal wire body 4 is located between the two abrasive belts 20).

[0032] Then, by controlling the two second electric telescopic rods 26, the two U-shaped sliding strips 25 are driven to move to appropriate positions, and then by controlling the driving part in the installation housing 22, the two mounting plates 231 on the U-shaped sliding strip 25 start to approach each other, so that the two pressure rollers 235 on the two mounting plates 231 approach each other and squeeze the two abrasive belts 20. Since two pressure rollers 235 are distributed on both sides of the metal wire body 4, therefore, the two abrasive belts 20 can be squeezed by the pressure rollers 235 on both sides of the metal wire body 4 and closely adhere to the upper half area and the lower half area of the metal wire body 4. At this time, the contact area between the abrasive belt 20 and the metal wire body 4 is large, so that the number of abrasive grains participating in grinding per unit time increases (the abrasive grains refer to the abrasive grains distributed on the surface of the abrasive belt 20), thereby effectively improving the grinding efficiency of the metal wire body 4.

[0033] When performing the above extrusion operation, the T-shaped strip 232 can limit the movement of the transmission block 233, that is, it can limit the extrusion distance of the pressure roller 235, so as to ensure that the two abrasive belts 20 will not come into contact due to the extrusion of the pressure roller 235, and further avoid affecting the normal use of the abrasive belt 20. If a metal wire rod body 4 with a smaller diameter is encountered, since the length of the abrasive belt 20 is unchanged, it is difficult to make the two abrasive belts 20 closely adhere to the surface of the metal wire rod body 4 only by the extrusion of the pressure roller 235. At this time, the third electric telescopic rod 241 can be controlled to make the two adjusting rollers 243 on the same side move away from each other and extrude the two abrasive belts 20. This staggered extrusion method of the pressure roller 235 and the adjusting roller 243 on the abrasive belt 20 can flexibly adjust the tension of the two abrasive belts 20 to keep them in a taut state, thus effectively ensuring that the abrasive belt 20 can closely adhere to the metal wire rod body 4 with different diameters and maintain a large contact area. This not only can avoid the influence of the slack of the abrasive belt 20 on its rotation smoothness, but also can effectively ensure the grinding effect on the surface of the metal wire rod body 4, that is, effectively ensure the grinding quality and grinding efficiency of the metal wire rod body 4 with different diameters.

[0034] When performing the grinding work, the motor 12 and the two drive motors work simultaneously. Under the action of the drive motors, the two driving rollers 18 start to rotate, so that the two driven rollers 19 and the two abrasive belts 20 start to rotate, that is, the two abrasive belts 20 start to rotate self-rotationally to grind the position where they contact the metal wire rod body 4. At the same time, under the action of the motor 12, the gear 13 starts to rotate, so that the driving gear ring 14 and the rotating housing 9 rotate synchronously. This rotational movement enables the two abrasive belts 20 to revolve around the metal wire rod body 4 while rotating self-rotationally. The combination of this revolution and self-rotation enables the abrasive belt 20 to continuously change its contact position with the metal wire rod body 4, thereby realizing the comprehensive grinding of the metal wire rod body 4, and further effectively improving the grinding quality. At the same time, the wire winding and unwinding device is turned on. Under the action of the wire winding and unwinding device, the metal wire rod body 4 can continuously move to one side, thereby realizing the continuous grinding operation of the metal wire rod body 4, and further improving the grinding efficiency of the metal wire rod body 4.

[0035] Since the pressure roller 235 is rotatably connected to the two transmission blocks 233, the pressure roller 235 can firmly press the abrasive belt 20 through the elastic force of the spring 234. The telescopic property of the spring 234 enables the pressure roller 235 to effectively cope with the slight displacement caused by vibration during the grinding and movement of the metal wire body 4. When the metal wire body 4 has a slight displacement, the pressure roller 235 can move flexibly accordingly, ensuring that under the combined action of the four pressure rollers 235, the pressure distribution between the metal wire body 4 and the abrasive belt 20 remains uniform, thereby improving the uniformity of grinding the metal wire body 4 (i.e., improving the grinding quality). If the spring 234 is not provided, when the metal wire body 4 has a small displacement, since the pressure roller 235 cannot adjust its position flexibly, there will be a large difference in the contact pressure between it and the two abrasive belts 20. Since the grinding effect is positively correlated with the pressure magnitude, this uneven pressure will cause the grinding degree on the surface of the metal wire body 4 to be uneven, that is, the phenomenon of uneven grinding occurs.

[0036] While starting the drive motor, by controlling the third electric telescopic rod 241, the two adjusting rollers 243 on the same side are respectively brought into contact with the two abrasive belts 20. Therefore, when the abrasive belt 20 rotates, the adjusting roller 243 will also rotate accordingly, that is, the adjusting roller 243 will rotate with the rotation of the abrasive belt 20, thereby reducing the friction between the abrasive belt 20 and the adjusting roller 243. At this time, the air pump 21 is turned on, and gas is filled into the shunt pipe 27 through the air pump 21. The gas entering the shunt pipe 27 will pass through the communication housing 242 under the action of the connecting hose 246 and finally be filled into the inside of the adjusting roller 243 through both ends of the adjusting roller 243. The gas filled into the inside of the adjusting roller 243 will be discharged through a plurality of air outlet grooves 244 thereon and blown onto the surface of the abrasive belt 20, thereby being able to blow off the dust adhered to the surface of the abrasive belt 20 due to the grinding operation, and further reducing the negative impact of the dust adhesion on the grinding effect of the abrasive belt 20 (if there is a lot of dust adhered to the abrasive belt 20, it will not only reduce the grinding effect of the abrasive belt 20, but also interfere with the normal grinding process of the metal wire body 4). In addition, the partition piece 245 on the adjusting roller 243 is used to partition the internal space thereof, thereby reducing the mutual interference between the gases filled from both ends of the adjusting roller 243 and ensuring that the gases discharged through the plurality of air outlet grooves 244 can be evenly, stably and powerfully blown onto the surface of the abrasive belt 20.

[0037] While blowing air onto the surface of the abrasive belt 20, turn on the dust collector 5. Since a plurality of dust suction holes are provided on one side of the dust suction frame 11 (the dust suction frame 11 does not contact the end cover 8), and a plurality of dust suction grooves are provided in the through hole three on the dust suction frame 11, therefore, under the action of the dust collector 5, not only can the dust inside the rotating housing 9 be sucked out through the dust suction holes to avoid dust dispersion, but also the dust attached to the outer surface of the metal wire rod body 4 can be specifically sucked out by the dust suction grooves, thereby preventing the dust attached to the metal wire rod body 4 from being discharged together with the metal wire rod body 4 to affect the product appearance (that is, effectively ensuring the product appearance after the metal wire rod body 4 is polished). In addition, during the process of sucking dust through the above-mentioned dust suction holes, the air with a higher temperature generated inside the installation cavity 17 due to the polishing of the metal wire rod body 4 by the abrasive belt 20 can be discharged, thereby reducing the temperature inside the installation cavity 17 and accelerating the air circulation inside it. Furthermore, to a certain extent, the temperature of the contact surface between the abrasive belt 20 and the metal wire rod body 4 can be reduced, the aging speed of the abrasive belt 20 can be decreased, and the service life of the abrasive belt 20 can be effectively improved.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
