Description
Technical Field
[0001] This utility model relates to the field of metal wire processing equipment, and in particular to a straight-line polishing machine. Background Technology
[0002] A linear polishing machine is a device that performs linear polishing. In metal wire processing, linear polishing machines are used to remove oxide layers, burrs, scratches, etc. from the surface of wires to improve surface smoothness and uniformity, in order to meet the needs of subsequent electroplating, coating, or direct use.
[0003] At present, most linear polishing machines on the market use the circumference of the abrasive belt or the rotating polishing disc to polish the wire: (1) Using the abrasive belt polishing method, the abrasive belt wears out quickly and needs to be replaced frequently, which affects the polishing efficiency. Moreover, after polishing, marks or scratches are easily formed on the surface of the wire, and the polishing effect is not ideal; (2) Using the circumference of the polishing disc polishing method, the contact area between the polishing disc and the surface of the wire is small, the polishing is not uniform, and the polishing effect is not ideal. Utility Model Content
[0004] In response to the shortcomings of existing linear polishing machines, the applicant provides a linear polishing machine with a reasonable structure, which uses the end face of a fine polishing wheel to polish the wire, resulting in high smoothness and uniformity of the polished wire.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A linear polishing machine includes a fine polishing device. Several sets of polishing components are arranged at intervals along the processing direction of the wire on the fine polishing device. Each set of polishing components is arranged at a different angle, and one set of polishing components completes the polishing of the two sides at a certain angle.
[0007] Each polishing assembly includes a set of two polishing wheels arranged face-to-face. The two polishing wheels are mounted on a main shaft, which is connected to a motor. A spring and a retaining sleeve are fitted on the main shaft. The retaining sleeve is fixedly connected to the main shaft. The spring is located between the polishing wheels and the retaining sleeve, with its two ends pressing against the polishing wheels and the retaining sleeve respectively. The two polishing wheels are pressed against each other under the action of the spring. The end faces of the polishing wheels that are pressed against each other are the polishing surfaces. During polishing, the wire passes between the polishing surfaces of the two polishing wheels for polishing.
[0008] As a further improvement to the above technical solution:
[0009] Each polishing wheel is fixedly connected to a connecting sleeve, which is fitted onto the main shaft, and a spring is pressed against the connecting sleeve.
[0010] The polishing wheel includes an annular base plate and an annular polishing layer. The polishing layer is axially positioned on one side of the base plate. The polishing layer includes several grinding layers and several cleaning layers. The grinding layers and cleaning layers are vertically positioned on the base plate along the axial direction and are stacked alternately along the circumferential direction.
[0011] The grinding layer uses abrasive cloth, and each grinding layer consists of a single sheet of sandpaper or two or more sheets of sandpaper with the same grit size stacked together; the cleaning layer uses scouring pad.
[0012] The base plate of the polishing wheel is provided with several first ear plates, which extend radially inward and have first connecting holes, which are elongated holes. The sleeve of the connecting sleeve is provided with several second ear plates, which extend radially outward and have second connecting holes. The second ear plates of the connecting sleeve correspond to the first ear plates of the polishing wheel, and the connecting sleeve and the polishing wheel are connected by fasteners at the second connecting holes and the first connecting holes.
[0013] On the fine polishing device, guide sleeve assemblies are respectively provided between the two sets of polishing components, on the inlet side of the first set of polishing components, and on the exit side of the last set of polishing components.
[0014] The fine polishing device has a water spray pipe interface at the inlet end of each polishing component. The water spray pipe interface is connected to a nozzle, which can spray water onto the wire at the inlet end of the polishing component.
[0015] The fine polishing device is connected to the circulating water tank through the inlet and outlet water pipes, and the spray pipe interface is connected to the inlet water pipe.
[0016] Along the wire processing direction, a coarse polishing device is installed before the fine polishing device; the coarse polishing device is equipped with a set of counter-rotating flaps, a turntable, a transmission shaft assembly, and a drive assembly, the drive assembly including a first drive group and a second drive group; the two flaps are connected to the turntable, the flaps are connected to the first drive group through a transmission structure, the turntable is connected to the transmission shaft assembly, and the transmission shaft assembly is connected to the second drive group through a transmission structure; along the wire processing direction, the flaps are in front and the transmission shaft assembly is behind; a through hole for the wire to pass through is opened in the center of the transmission shaft assembly.
[0017] The coarse polishing device is connected to the circulating water tank through the inlet and outlet pipes; the coarse polishing device and the fine polishing device are mounted on the frame, and the circulating water tank is located on one side of the frame; the inlet pipe of the coarse polishing device is also equipped with a spray pipe interface, and a nozzle is connected to the spray pipe interface, which can spray water onto the wire at the feed end of the impeller.
[0018] The beneficial effects of this utility model are as follows:
[0019] The precision polishing device of this invention uses a set of precision polishing wheels with their faces pressed together to polish the wire at a specific angle. By cooperating with several sets of polishing components evenly distributed along the circumference, the entire circumference of the wire is polished. The contact area between the end face of the precision polishing wheel and the outer surface of the wire is large, the polishing is more uniform, and the surface of the wire is smoother after polishing.
[0020] In this invention, the two polishing wheels of the polishing assembly are held together by the elastic force of a spring. Even if the polishing surface of the polishing wheels is worn, the spring can be adjusted to keep the two polishing wheels in close contact, thus ensuring the polishing effect.
[0021] The present invention features a polishing wheel with several grinding and cleaning layers arranged circumferentially. Polishing and cleaning are performed simultaneously, and the abrasive material generated during polishing is promptly carried away by the water flow. This ensures that the abrasive in the grinding layers remains sharp, resulting in better grinding effect, longer service life, and higher surface smoothness and uniformity of the polished wire.

[0037] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0038] like Figures 1 to 3 As shown, a coarse polishing device 200 and a fine polishing device 300 are sequentially arranged on the frame 100 of this utility model along the processing direction of the wire 500. A circulating water tank 400 is provided on one side of the frame 100. The coarse polishing device 200, the fine polishing device 300 and the circulating water tank 400 are respectively connected by an inlet pipe 70 and an outlet pipe 80. The circulating water tank 400 provides rinsing water to the wire 500 through the inlet pipe 70. The rinsed water flows back to the circulating water tank 400 through the outlet pipe 80 to settle clean, is filtered and then recycled.
[0039] like Figure 1 , Figure 3 , Figure 4 As shown, the coarse polishing device 200 is equipped with a set of counter-rotating flap wheels 10, a turntable 20, a transmission shaft assembly 30, and a drive assembly 90. The drive assembly 90 includes a first drive group 901 and a second drive group 902. The two flap wheels 10 are connected to the turntable 20. The flap wheels 10 are connected to the first drive group 901 through a transmission structure. The first drive group 901 drives the two flap wheels 10 to rotate (accelerating their rotation based on the existing revolution and rotation of the second drive group 902). The turntable 20 is connected to the transmission shaft assembly 30. The transmission shaft assembly 30 is connected to the second drive group 902 through a transmission structure. The second drive group 902 drives the turntable 20 to rotate through the transmission structure and the transmission shaft assembly 30, thereby driving the two flap wheels 10 to revolve and rotate. Along the processing direction of the wire 500, the flap wheels 10 are in front, and the transmission shaft assembly 30 is behind. The flap wheels 10 perform coarse polishing on the wire 500 through their rotation and revolution. The drive shaft component 30 has a through hole 301 in the center, through which the wire 500 passes.
[0040] like Figures 1 to 3As shown, the polishing device 300 is provided with several sets of polishing components 40 at intervals along the processing direction of the wire 500. The number of polishing components 40 is at least three sets, and ten sets are provided in this embodiment. The arrangement angle of each set of polishing components 40 is different, such as... Figure 5 The angles of several sets of polishing components 40 are evenly distributed circumferentially within a range of 180 degrees. In this embodiment, the ten sets of polishing components 40 have an angle of 18 degrees for the first set, 36 degrees for the second set, ..., and 180 degrees for the tenth set. Each set of polishing components 40 completes the polishing of the surfaces on both sides of a certain angle. In this embodiment, the first set of polishing components 40 completes the surface polishing of the wire 500 at 18 degrees and 198 degrees, the second set completes the surface polishing of the wire 500 at 36 degrees and 216 degrees, ..., and the tenth set completes the surface polishing of the wire 500 at 180 degrees and 360 degrees. After the wire 500 passes through the fine polishing device 300, the polishing components 40 at different angles work together to complete the 360-degree polishing of the entire circumference of the wire 500.
[0041] On the fine polishing device 300, guide sleeve assemblies 50 are respectively provided between the two sets of polishing components 40, on the wire inlet side of the first set of polishing components 40, and on the exit side of the last set of polishing components 40. The guide sleeve assemblies 50 support and guide the wire 500 to ensure the linear travel of the wire 500.
[0042] like Figure 6 As shown, the polishing device 300 has a water spray pipe interface 60 at the inlet end of each polishing assembly 40. The water spray pipe interface 60 is connected to the water inlet pipe 70, and a nozzle (not shown in the figure) is connected to the water spray pipe interface 60. The nozzle can spray water onto the wire 500 at the inlet end of the polishing assembly 40. On the one hand, the sprayed water can rinse the wire 500 that is about to enter the polishing assembly 40 and cool it down. The sprayed water flows into the polishing assembly 40 along with the wire 500 and comes into contact with the abrasive in the polishing assembly 40, preventing damage. The 500 wire generates heat during polishing, ensuring the structural stability of the 500 wire and resulting in more consistent quality. Furthermore, water washing removes dust, preventing dust generation and offering a safer alternative to traditional dust collectors, as it is non-flammable. The water flow also carries away abrasive particles, making them sharper and extending their lifespan. These particles are then carried into the circulating water tank 400 for sedimentation and filtration, creating a cleaner and more environmentally friendly working environment. Additionally, rust inhibitors or other coating agents can be added to the spray water, combining rust prevention and coating for the 500 wire. Figure 4 As shown, a water spray pipe interface 60 is also provided on the water inlet pipe 70 of the coarse polishing device 200. A nozzle (not shown in the figure) is connected to the water spray pipe interface 60. The nozzle can spray water onto the wire 500 at the inlet end of the impeller 10 for cooling and dust removal.
[0043] like Figure 7As shown, each polishing assembly 40 includes a set of polishing wheels 1 arranged face-to-face. The end faces of the two polishing wheels 1 facing each other form the polishing surface. During polishing, the wire 500 passes between the polishing surfaces of the two polishing wheels 1 for polishing. The two polishing wheels 1 are mounted on the same spindle 3, which is connected to a motor 4. The motor 4 drives the two polishing wheels 1 to rotate together in the same direction via the spindle 3, and the polishing surfaces of the two polishing wheels 1 polish the wire 500. A connecting sleeve 2 is fixedly connected to each polishing wheel 1, and the connecting sleeve 2 is fitted onto the spindle 3. On the main shaft 3, a spring 5 and a fixing sleeve 6 are respectively fitted on each polishing wheel 1. The fixing sleeve 6 is fixed on the main shaft 3. The spring 5 is located between the connecting sleeve 2 and the fixing sleeve 6. The spring 5 is in a compressed state, with one end pressed against the connecting sleeve 2 and the other end pressed against the fixing sleeve 6. The two polishing wheels 1 are pressed against each other when the spring 5 is in action. The two polishing wheels 1 are pressed against each other by the elastic force of the spring 5. Even if the polishing surface of the polishing wheel 1 is worn, the spring 5 can keep the two polishing wheels 1 pressed against each other by adjusting the amount of compression, so as to ensure the polishing effect.
[0044] like Figure 8 As shown, the polishing wheel 1 includes an annular base plate 11, with an annular polishing layer 12 axially arranged on one side surface of the base plate 11. Several first ear plates 111 are arranged circumferentially on the inner side of the base plate 11, extending radially inward. Each ear plate 111 has a first connecting hole 112, which is an elongated hole to facilitate angle adjustment of the polishing wheel 1. The polishing layer 12 includes several grinding layers 121 and several cleaning layers 122. The grinding layers 121 and cleaning layers 122 are vertically arranged axially on the base plate 11, and are stacked circumferentially to form an annular shape. The grinding layers 121 are made of abrasive paper and mainly function as grinding surfaces for polishing the wire 500. Each grinding layer 121 can be a single sheet of abrasive paper or composed of two or more sheets of abrasive paper of the same grit size stacked together. The cleaning layer 122 uses a scouring pad, which mainly serves a cleaning function, removing water and abrasive particles. The polishing wheel 1, through several circumferentially spaced grinding layers 121 and cleaning layers 122, polishes and cleans simultaneously, ensuring that the abrasive particles generated during polishing are promptly removed by the water flow. This guarantees that the abrasive in the grinding layer 121 remains sharp, resulting in better grinding performance, longer service life, and higher surface smoothness and uniformity after polishing the wire 500.
[0045] like Figure 9 As shown, the connecting sleeve 2 includes a sleeve 21 fitted onto the main shaft 3. Several second ear plates 22 are arranged circumferentially around the outer periphery of the sleeve 21. The second ear plates 22 extend radially outward, and second connecting holes 23 are formed on the second ear plates 22. Figure 7As shown, the second ear plate 22 of the connecting sleeve 2 corresponds to the first ear plate 111 of the polishing wheel 1. The connecting sleeve 2 and the polishing wheel 1 can be fixedly connected by fasteners at the second connecting hole 23 of the second ear plate 22 and the first connecting hole 112 of the polishing wheel 1.
[0046] In actual use, the wire 500 is rough polished and straightened by the rough polishing device 200, and then sent to the fine polishing device 300. After the polishing of the entire circumference of the wire 500 is completed by the cooperation of several sets of polishing components 40 at different angles, it is sent out.
[0047] The precision polishing device 300 of this utility model uses a set of precision polishing wheels 1 with their faces pressed together to polish the wire 500 at a specific angle. By cooperating with several sets of polishing components 40 evenly distributed along the circumference, the entire circumference of the wire 500 is polished. The contact area between the end face of the precision polishing wheel 1 and the outer surface of the wire 500 is large, the polishing is more uniform, and the surface of the wire 500 is smoother after polishing.
[0048] The above description is an explanation of the present utility model and not a limitation thereof. The present utility model can be modified in any form without departing from its spirit.
