Description

Technical Field

[0001] The invention relates to the technical field of tin-phosphor bronze surface treatment, in particular to a device for removing an oxide layer on the surface of tin-phosphor bronze before hot rolling treatment. Background Art

[0002] Tin-phosphor bronze is widely used in high-load friction components such as bearings and gears due to its excellent corrosion resistance, high elastic modulus, and fatigue resistance. To meet the demands of complex operating conditions, the material is often processed into round rolls to achieve uniform load distribution, reduce stress concentration, and improve adaptability to heat treatment processes. However, the removal of the surface oxide layer before hot rolling presents significant technical bottlenecks.

[0003] Traditional processes use chemical polishing or mechanical grinding to remove the oxide layer, but this method cannot completely remove stubborn oxide layers. More critically, existing processes lack the hammering treatment of the round tin-phosphorus bronze roll, resulting in three core defects: First, the residual oxide layer is pressed into the substrate during hot rolling, forming a source of microcracks and significantly reducing the material's fatigue life; second, the surface roughness caused by grinding exacerbates hot rolling stress concentration, increasing the risk of cracking; and finally, the work-hardened layer that is not released by hammering reduces the material's plasticity, affecting the subsequent forming accuracy.

[0004] In view of this, a device for removing the surface oxide layer of tin-phosphorus bronze before hot rolling is proposed to solve the above problems. Summary of the Invention

[0019] Compared with the prior art, the present invention provides a device for removing the surface oxide layer of tin-phosphor bronze before hot rolling treatment, which has the following beneficial effects:

[0020] 1. This device for removing the oxide layer on the surface of tin-phosphorus bronze before hot rolling treatment uses a striking block that is linked to the wave groove of the limit plate through a connecting frame. When the grinding mechanism moves horizontally, the roller rolls along the wave groove, forcing the connecting frame to drive the striking block to move up and down. The periodic fluctuation of the wave groove causes the striking block to hammer the workpiece surface at a fixed frequency, generating instantaneous impact force, effectively stripping off the oxide layer with strong adhesion. The rotating friction with the grinding pad also forms a dual effect of mechanical stripping and friction removal.

[0021] 2. The device for removing the oxide layer on the surface of tin-phosphorus bronze before hot rolling treatment has a wave groove of the limit plate with a periodic undulating structure. Its shape, such as the peak height and wavelength, directly determines the knocking frequency and amplitude. By replacing the limit plate with different wave groove specifications, it can adapt to different oxide layer thicknesses or workpiece hardness. The wave groove extends along the axial direction of the workpiece to ensure that the knocking block vibrates uniformly within the entire processing width, avoiding excessive or insufficient local processing.

[0022] 3. This device for removing the oxide layer on the surface of tin-phosphorus bronze before hot rolling treatment uses a liquid infusion mechanism that achieves efficient, uniform, and environmentally friendly treatment of the oxide layer on the surface of tin-phosphorus bronze through the multiple functions of power coupling, precise liquid supply, dynamic compensation, and chemical liquid. Its advantages include adaptive adjustment of liquid supply volume, precise cooling of the processing area, and real-time debris removal, which significantly improves processing quality and production efficiency while reducing energy consumption and waste emissions.

[0023] 4. This device for removing the oxide layer on the surface of tin-phosphorus bronze before hot rolling treatment uses a high-frequency vibration hammer to strike the workpiece surface, generating an instantaneous impact force that causes local plastic deformation on the material surface. According to Hertz contact theory, stress concentration in the contact area forces the material to produce minute deformations, thereby changing the stress distribution in the surrounding area. In addition, the vibration waves generated by the high-frequency striking propagate within the material, stimulating dislocation movement and grain boundary sliding. According to the principle of vibration aging, the vibration energy causes the microscopic residual stress within the material to be reduced through the release of elastic strain energy. Vibration relaxes the residual stress within the material, making it particularly suitable for materials that are prone to work hardening, such as tin-phosphorus bronze, and can reduce the tendency to deform during subsequent heat treatment or use.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 6 In this embodiment, a device for removing the surface oxide layer of tin-phosphor bronze before hot rolling treatment includes a support structure 1 for supporting a grinding mechanism 4, and a chuck 2 and a driving mechanism 3 used in conjunction with the grinding mechanism 4 are provided on the support structure 1. A knocking mechanism 5 and a limit plate 6 for treating the tin-phosphor bronze are provided on one side of the grinding mechanism 4. The support structure 1 is also provided with an infusion mechanism 7 used in conjunction with the grinding mechanism 4; the support structure 1 includes a base plate 101, and a first support seat 102 and a third support seat 104 are welded and installed on the upper surface of the base plate 101. A second support seat 103 is slidably provided on the upper surface of the base plate 101, and a chuck 2 is provided between the opposite sides of the first support seat 102 and the second support seat 103.

[0033] In order to achieve clamping flexibility, the support structure 1 also includes an electric telescopic rod 105 fixed on the third support seat 104, and the output end of the electric telescopic rod 105 is fixed to the outer wall of the second support seat 103. Two sets of guide rails are fixed on the upper surface of the base plate 101, and the second support seat 103 is slidably connected to the guide rails. The electric telescopic rod 105 pushes the second support seat 103 to move horizontally, and cooperates with the first support seat 102 to realize automatic clamping of the workpiece through the chucks 2 on both sides, adapting to workpieces of different lengths, reducing manual adjustment time, and improving production flexibility. It should be noted that the support structure 1 realizes the automation, precision and efficiency of the clamping of tin-phosphor bronze workpieces through the coordinated design of the electric telescopic rod 105 and the guide rail, while ensuring the stability of the processing process and the overall rigidity of the device. This design not only improves the quality of oxide layer removal, but also significantly enhances the adaptability of the device to different production needs. A collection structure can be set on the upper surface of the base plate 101.

[0034] The driving mechanism 3 includes a driving motor 301, a driving shaft 302 and a lead screw 307 for displacing the grinding mechanism 4. A gear is provided between the driving motor 301 and the driving shaft 302. The driving motor 301 is a dual-axis motor, and a synchronizer is provided between the other output shaft and the lead screw 307. The top sides of the first support seat 102 and the third support seat 104 are fixed with a limit seat for limiting the position of the lead screw 307. The two ends of the lead screw 307 are axially limited to prevent axial movement when the lead screw 307 rotates. Specifically, the driving motor 301 is fixed on the first support seat 102, the driving shaft 302 is connected to the internal bearing of the first support seat 102, and one end of the driving shaft 302 is fixed to the outer wall of the left chuck 2. The gear is composed of a meshing transmission gear 303 and a driven gear 304. The transmission gear 303 is fixed to the right output shaft of the driving motor 301, and the driven gear 304 is fixed to the outer surface of the driving shaft 302. Specifically, the synchronizer includes two synchronizer wheels 305, which are respectively fixed to the end of the lead screw 307 and the left output shaft of the drive motor 301. A synchronizer belt 306 is connected between the two synchronizer wheels 305. The two synchronizer wheels 305 are set in different sizes. The drive motor 301 is a dual-axis motor. The right output shaft drives the drive shaft 302 to rotate through the gear transmission gear 303 and the driven gear 304, thereby driving the left chuck 2 and the workpiece to rotate; the left output shaft drives the lead screw 307 to rotate through the synchronizer synchronizer wheel 305 and the synchronizer belt 306, thereby controlling the horizontal displacement of the grinding mechanism 4. It is worth mentioning that the combined transmission of the gear and the synchronizer belt 306 ensures that the rotation speed of the workpiece and the moving speed of the grinding mechanism 4 are accurately matched, thereby avoiding uneven surface treatment caused by speed differences.

[0035] To achieve surface treatment of the phosphorus bronze roller, the grinding mechanism 4 includes a grinding block 401. A first connecting block 402 is welded to the top of the grinding block 401. A second connecting block 404, which limits the position of the connecting frame 503, is fixed to the outer wall of the first connecting block 402. A grinding pad 403 is embedded within the grinding block 401. The first connecting block 402 is threadedly connected to the lead screw 307. A guide plate 405 is fixed to the outer wall of the first connecting block 402 to guide the shaft 507. It should be noted that the curved surface of the grinding pad 403 conforms to the surface of the phosphorus bronze roller workpiece. Through the combined motion of the workpiece's rotation and the horizontal movement of the grinding mechanism 4, spiral grinding is achieved.

[0036] To improve the surface treatment effect of the tin-phosphor bronze of the round roller, the striking mechanism 5 includes a striking block 501 and a connecting frame 503 disposed above the striking block 501. The bottom side of the connecting frame 503 is fixed with a mounting shaft 502 for mounting the striking block 501. The mounting shaft 502 is a telescopic structure. The top side of the connecting frame 503 is provided with a connecting piece for use with the limit plate 6. The connecting frame 503 passes through the interior of the second connecting block 404, and a circular pad 505 is fixed to the outer surface of the connecting frame 503. A buffer spring 504 is fixed between the circular pad 505 and the second connecting block 404. The striking block 501 is fixed to the bottom end of the mounting shaft 502 by bolts, and a buffer pad 509 is fixed to the inner side of the striking block 501. Specifically, the connecting member includes a connecting end 506 fixed to the top side of the connecting frame 503, a shaft 507 is fixed inside the connecting end 506, a roller 508 is mounted on a bearing at one end of the shaft 507, and a wave groove 61 adapted to the roller 508 is opened inside the limiting plate 6. It should be noted that the knocking block 501 is linked to the wave groove 61 of the limiting plate 6 through the connecting frame 503. When the grinding mechanism 4 moves horizontally, the roller 508 rolls along the wave groove 61, forcing the connecting frame 503 to drive the knocking block 501 to move up and down. The periodic fluctuation of the wave groove 61 causes the knocking block 501 to hammer the surface of the workpiece at a fixed frequency, generating an instantaneous impact force, effectively stripping off the oxide layer with strong adhesion, and forming a dual effect of "mechanical stripping and friction removal" with the rotating friction of the grinding pad 403, which is particularly suitable for materials such as tin-phosphor bronze with a dense oxide layer and strong bonding with the substrate. The buffer pad 509 is fixed on the inner side of the striking block 501 and directly contacts the surface of the workpiece. The buffer spring 504 limits the upper limit of the striking force to avoid depression or deformation of the workpiece surface due to excessive vibration. Since tin-phosphor bronze is soft in texture, the buffer pad 509 uses flexible materials such as rubber or polyurethane to disperse the impact force and prevent knock marks.

[0037] In addition, the wave groove 61 of the limiting plate 6 is a periodic undulating structure, and its shape, such as the peak height and wavelength, directly determines the knocking frequency and amplitude. By replacing the limiting plate 6 with different specifications of the wave groove 61, it can adapt to different oxide layer thicknesses or workpiece hardnesses. The wave groove 61 extends along the axial direction of the workpiece to ensure that the knocking block 501 vibrates uniformly within the entire processing width, avoiding excessive or insufficient local processing.

[0038] It is worth mentioning that when the striking block 501 vibrates and hammers the surface of the workpiece with high frequency, the instantaneous impact force generated will cause local plastic deformation on the material surface. According to Hertz contact theory, the stress concentration in the contact area will force the material to produce small deformations, thereby changing the stress distribution in the surrounding area. In addition, the vibration waves generated by high-frequency striking propagate inside the material, stimulating dislocation movement and grain boundary sliding. According to the principle of vibration aging, the vibration energy causes the microscopic residual stress inside the material to be reduced through the release of elastic strain energy. Vibration relaxes the residual stress inside the material, which is especially suitable for materials such as tin-phosphorus bronze that are prone to work hardening, and can reduce the tendency to deform during subsequent heat treatment or use.

[0039] Among them, a guide block 63 and a connecting arm 62 for fixing are fixed on the outer wall of the limit plate 6, and the connecting arm 62 is fixed to the limit seat bolt. The outer surface of the guide block 63 is slidably mounted with a sliding sleeve 604 fixed to the outer wall of the second connecting block 404. The cooperation between the guide block 63 and the sliding sleeve 604 limits the connection frame 503 to move only in the vertical direction, avoiding the lateral offset of the knocking block 501 causing the knocking force to be dispersed or the surface of the workpiece to be scratched. The vertical guide ensures that the knocking position is accurate each time, which meets the requirements of high-precision processing. Replace the knocking block 501 with different hardness or shape to adapt to different workpieces, or adjust the material of the buffer pad 509 to optimize the protection effect.

[0040] In order to further improve the treatment effect, the infusion mechanism 7 includes a pump body 701 and a nozzle 705 arranged on the grinding mechanism 4, and a connecting pipe is provided between the pump body 701 and the nozzle 705. The pump body 701 is fixed to the outer wall of the first support seat 102 by bolts. The pump body 701 is a gear pump, and the gear rotor inside the pump body 701 is fixed to the left end of the drive shaft 302. The nozzle 705 is fixed to the outer surface of the grinding block 401, and a number of equidistantly distributed spray holes 706 are opened inside the nozzle 705. The nozzle 705 is adjacent to the grinding area, and the chemical liquid is directly sprayed onto the surface of the workpiece, quickly reducing the temperature of the grinding area to prevent the tin-phosphor bronze from softening due to overheating or sintering of the oxide layer. It should be noted that the equidistant nozzles 706 ensure that the chemical liquid is evenly distributed along the axial direction of the workpiece to avoid uneven treatment caused by excessively high or low local concentrations. The nozzle 705 is annular in shape, and there are two nozzles 705, symmetrically distributed on the left and right sides of the grinding block 401. A connecting pipe is installed between the two nozzles 705. Specifically, the connecting pipeline includes a first infusion pipe 702 fixed to the output and input ends of the pump body 701. The first infusion pipe 702 on the output end is flange-connected to a bellows expansion pipe 703. The bellows structure can axially expand and contract to compensate for the pipeline stress generated by the movement of the grinding mechanism 4 and prevent loosening or leakage at the connection. The other end of the bellows expansion pipe 703 is fixed to a second infusion pipe 704 connected to the nozzle 705. The infusion mechanism 7 achieves efficient, uniform, and environmentally friendly treatment of the oxide layer on the surface of tin-phosphorus bronze through the multiple effects of power coupling, precise liquid supply, dynamic compensation, and chemical liquid. Its advantages include adaptive adjustment of the liquid supply volume, precise cooling of the processing area, and real-time removal of debris, which significantly improves the processing quality and production efficiency while reducing energy consumption and waste emissions. In addition, a sprayed chemical liquid, such as an acidic or complexing agent solution, reacts chemically with the oxide layer, accelerating its dissolution or peeling. Other cooling liquids can also be sprayed to reduce the friction coefficient between the polishing pad 403 and the workpiece surface, reduce heat generation, and extend the life of the polishing pad 403. It should be noted that the chemical liquid can clean the workpiece surface, exposing a fresh metal substrate and improving the adhesion of subsequent electroplating or coating.

[0041] The working principle of the above embodiment is:

[0042] First, the workpiece is placed between the two chucks on both sides, and the electric telescopic rod 105 pushes the second support base 103 to move to achieve automatic clamping;

[0043] The driving motor 301 is started, and the screw 307 is driven to rotate through the synchronous wheel 305 and the synchronous belt 306, driving the grinding mechanism 4 to move horizontally. At this time, the knocking mechanism 5 set on the grinding block 401 moves accordingly, and the roller 508 moves along the wave groove 61 of the limit plate 6, forcing the connecting frame 503 to reciprocate up and down, so that the knocking block 501 hammers the surface of the workpiece at a high frequency. At the same time, the buffer spring 504 absorbs the impact force to prevent overload;

[0044] Then the right end of the driving motor 301 drives the driving shaft 302 through the gear to rotate the chuck 2 to drive the workpiece to rotate. At the same time, the polishing pad 403 contacts the surface of the workpiece to polish. The left end of the driving shaft 302 is linked to the pump body 701 to pump the chemical liquid through the bellows 703 and the nozzle 705 to evenly cover the surface of the workpiece.

[0045] Finally, the electric telescopic rod 105 is retracted, and the chuck 2 is released to remove the workpiece.

[0046] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
