Description

Technical Field

[0001] This application relates to the field of strip grinding, and in particular to abrasive belt grinding equipment for copper alloy strips. Background Technology

[0002] With the increasing demand for high-strength and lightweight materials in fields such as aerospace, new energy vehicles, and high-end equipment manufacturing, C19900 alloy has become a research hotspot due to its excellent strength, corrosion resistance, and processing performance. During the cold rolling process, C19900 is prone to forming a mixed layer of Cu2O (cuprous oxide) and TiO2. When annealed at a temperature exceeding 200℃, it is prone to forming CuO (black, thickness > 100nm) + TiO2 (dense oxide layer), resulting in a blackened surface.

[0003] In the prior art, chemical methods such as pickling are used to remove the oxide layer on the surface of C19900 alloy. However, the above chemical removal methods can lead to pollution and may also result in resource waste.

[0004] Therefore, it is necessary to develop abrasive belt grinding equipment for copper alloy strips to remove the oxide layer mechanically, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a sanding belt grinding device for copper alloy strips, which aims to solve the problem that the existing technology uses chemical methods such as acid pickling to remove the oxide layer on the surface of C19900 alloy. However, the above-mentioned chemical removal methods can lead to pollution and may also result in resource waste.

[0006] To achieve the above objectives, this application proposes a belt abrasive grinding device for copper alloy strip, comprising a frame, a conveyor belt mounted on the frame, and copper alloy strip placed on the conveyor belt. The device further comprises: a first drive roller rotatably mounted on the frame; a first driven roller rotatably mounted on the frame; an abrasive belt rotatably connected to the outer sides of the first drive roller and the first driven roller; and a limiting groove provided on the conveyor belt to accommodate the copper alloy strip.

[0007] In some embodiments, the device further includes: a pressure roller rotatably disposed on the frame; and a pressure member disposed on the outside of the pressure roller, the pressure member abutting against the copper alloy strip.

[0008] In some embodiments, it further includes: an auxiliary limiting member, wherein the conveyor belt is provided with an auxiliary limiting member.

[0009] In some embodiments, the device further includes: a first rotary power source, which is disposed on the frame and connected to a first drive roller.

[0010] In some embodiments, the device further includes: a second rotary power source disposed on the frame; a second drive roller rotatably disposed on the frame, the second rotary power source being connected to the second drive roller; and a second driven roller rotatably disposed on the frame, the conveyor belt being rotatably connected to the outside of the second drive roller and the second driven roller.

[0011] In some embodiments, it further includes: a support platform, which is disposed on the frame, and a portion of the conveyor belt contacts the support platform.

[0012] This application proposes a belt abrasive grinding device for copper alloy strips, including a frame with a conveyor belt on the frame. The copper alloy strip is placed on the conveyor belt. The device further includes: a first drive roller rotatably mounted on the frame; a first driven roller rotatably mounted on the frame; an abrasive belt rotatably connected to the outside of the first drive roller and the first driven roller; and a limiting groove on the conveyor belt to accommodate the copper alloy strip. During the grinding process, the copper alloy strip is placed on the conveyor belt, which moves the strip towards the abrasive belt, thus grinding the strip and removing the oxide layer. The limiting groove on the conveyor belt restricts the lateral movement of the copper alloy strip, preventing it from shifting during grinding and affecting the grinding effect.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] See Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, this application proposes a belt abrasive grinding equipment for copper alloy strip, including a frame 1, a conveyor belt 9 disposed on the frame 1, a copper alloy strip 6 placed on the conveyor belt 9, and further including: a first drive roller 12, which is rotatably disposed on the frame 1; a first driven roller 4, which is rotatably disposed on the frame 1; an abrasive belt 2, which is rotatably connected to the outside of the first drive roller 12 and the first driven roller 4; and a limiting groove 91, which is disposed on the conveyor belt 9 to accommodate the copper alloy strip 6.

[0017] The frame 1 serves as the structural foundation for the belt abrasive grinding equipment used for copper alloy strips. All other structures on the equipment are directly or indirectly mounted on the frame 1. The conveyor belt 9 is rotatably mounted on the frame 1. The conveyor belt 9 carries the copper alloy strip 6 and moves it to the underside of the abrasive belt 2 to complete the grinding of the copper alloy strip 6 and remove the oxide layer.

[0018] The first driving roller 12 and the first driven roller 4 together tension the abrasive belt 2 to maintain its shape. The rotation of the first driving roller 12 drives the abrasive belt 2 to rotate, thereby abrading the copper alloy strip 6 on the conveyor belt 9 and removing the oxide layer from it. Bearing supports are provided on both sides of the first driving roller 12 and the first driven roller 4, and the first driving roller 12 and the first driven roller 4 are rotatably mounted to the frame 1 via the bearing supports.

[0019] In this embodiment, as the sanding belt 2 rotates continuously, the conveyor belt 9 also rotates at a low speed, causing the unpolished portion of the copper alloy strip 6 to continuously move towards the sanding belt 2, while the portion of the copper alloy strip 6 with the oxide layer removed is continuously moved away from the sanding belt 2 by the conveyor belt 9. Preferably, the frame 1 is equipped with two sets of first driving rollers 12, first driven rollers 4, and sanding belts 2. The two sanding belts 2 are spaced apart along the length of the conveyor belt 9, allowing the copper alloy strip 6 to be polished twice in sequence, thus more effectively removing the oxide layer on the copper alloy strip 6.

[0020] The limiting groove 91 is one of the core structures of the grinding equipment. During the grinding process of the copper alloy strip 6, the copper alloy strip 6 is placed in the limiting groove 91. The limiting groove 91 restricts the left and right movement of the copper alloy strip 6, preventing it from moving left and right during the grinding process of the abrasive belt 2, which would affect the grinding effect. The depth of the limiting groove 91 is less than the thickness of the copper alloy strip 6. Preferably, the depth of the limiting groove 91 is half the thickness of the copper alloy strip 6.

[0021] Specifically, during the grinding process of the copper alloy strip 6, the copper alloy strip 6 is placed on the conveyor belt 9, which moves the copper alloy strip 6 towards the abrasive belt 2. The abrasive belt 2 then grinds the copper alloy strip 6, removing the oxide layer. Furthermore, the limiting groove 91 on the conveyor belt 9 restricts the lateral movement of the copper alloy strip 6, preventing it from shifting laterally during the grinding process and affecting the grinding effect.

[0022] In detail, the copper alloy strip 6 is polished using abrasive belt 2 to remove the oxide layer. The entire process does not use strong acids (such as hydrochloric acid and sulfuric acid), strong alkalis, or other corrosive chemicals. It does not generate acidic or alkaline wastewater or waste liquid containing heavy metals that would require costly treatment. This avoids complex wastewater treatment systems and environmental approval issues, and the operation is safer. During the polishing process, countless abrasive grains impact the metal surface at high speed, causing slight plastic deformation and forming a hardened layer, which improves the fatigue strength and wear resistance of the metal strip. Furthermore, while removing the oxide layer, it thoroughly removes other impurities from the surface, resulting in a highly clean and activated metal surface, which is highly beneficial for subsequent electroplating, spraying, and other processes, enhancing coating adhesion.

[0023] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the machine further includes: a pressure roller 14, which is rotatably mounted on the frame 1, with bearing supports at both ends, and is rotatably mounted on the frame 1 via the bearing supports; and a pressure member 15, which is located on the outside of the pressure roller 14 and abuts against the copper alloy strip 6. The pressure member 15 is made of rubber or sponge, and the distance between the axis of the pressure member 15 and the copper alloy strip 6 is less than the diameter of the pressure member 15. The pressure member 15 presses the copper alloy strip 6, reducing the probability of the copper alloy strip 6 folding, which is beneficial to the stable operation of the grinding process. Pressure rollers 14 are provided on both sides of the sanding belt 2. Preferably, two pressure rollers 14 are provided between the two sanding belts 2, and two pressure rollers 14 are provided on the opposite sides of the two sanding belts 2.

[0024] In this embodiment, the clamping member 15 has an opening and is sleeved on the clamping roller 14. The clamping roller 14 has a shoulder for positioning the clamping member 15. The clamping member 15 is deformed and sleeved onto the clamping roller 14. The clamping member 15 can clean the grinding surface of the copper alloy strip 6 before grinding, preventing dirt on the copper alloy strip 6 from directly contacting the abrasive belt 2 and extending the service life of the abrasive belt 2. More preferably, the clamping member 15 is supported by a sponge and is impregnated with cleaning fluid to better clean the grinding surface of the copper alloy strip 6, and the cleaning fluid also helps to quickly cool the copper alloy strip 6.

[0025] See Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, an auxiliary limiting member 92 is also included, which is provided on the conveyor belt 9. The auxiliary limiting member 92 is bonded to both sides of the limiting groove 91. The setting of the auxiliary limiting member 92 can change the width of the limiting groove 91, so that the limiting groove 91 can adapt to copper alloy strips 6 of different widths, enhancing the practicality of the grinding equipment.

[0026] See Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, it further includes: a first rotary power source 8, which is a motor, and is mounted on the frame 1. A second rotary power source 11 is mounted on the frame 1 by screws. The first rotary power source 8 is connected to a first drive roller 12. The output end of the first rotary power source 8 is connected to a first drive shaft via a coupling. A first drive wheel is mounted on the first drive shaft. A first drive shaft is welded to the first drive roller 12. The first drive shaft is mounted on the frame 1 via a bearing bracket. A second drive wheel is welded to the first drive shaft. A drive belt 7 is provided between the first drive wheel and the second drive wheel to transmit power from the first rotary power source 8 to the first drive roller 12, driving the first drive roller 12 to rotate, thereby driving the sanding belt 2 to rotate.

[0027] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, it further includes: a second rotary power source 11, which is disposed on the frame 1 and is a motor, and is mounted on the frame 1 by screws; a second drive roller 10, which is rotatably disposed on the frame 1 and connected to the second drive roller 10 by the second rotary power source 11; and a second driven roller 5, which is rotatably disposed on the frame 1, and the conveyor belt 9 is rotatably connected to the outside of the second drive roller 10 and the second driven roller 5. The second driving roller 10 and the second driven roller 5 together tension the conveyor belt 9 to maintain the shape of the conveyor belt 9. The second driving roller 10 and the second driven roller 5 are both mounted on the frame 1 through bearing brackets. The bearing brackets are mounted on the frame 1 with screws. The output end of the second rotary power source 11 is connected to the second drive shaft through a coupling. The first helical gear is welded on the second drive shaft. The second driving roller 10 is provided with a second driving shaft. The second driving shaft is mounted on the frame 1 through bearing brackets. The second driving shaft is welded with a second helical gear. The second helical gear meshes with the first helical gear to transmit power to the second driving roller 10.

[0028] See Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the system further includes a support platform 13, which is disposed on the frame 1, and a portion of the conveyor belt 9 contacts the support platform 13. The support platform 13 is used to support the conveyor belt 9, and the portion of the conveyor belt 9 that contacts the copper alloy strip 6 is in contact with the support platform 13 to effectively support the conveyor belt 9 and prevent the conveyor belt 9 from deforming under the weight of the copper alloy strip 6, the pressure of the clamping member 15, or the pressure of the sand belt 2.
