[0001] The invention relates to the technical field of strip steel processing, and in particular to a strip steel grinding device for processing a cable bridge. Background Art

[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. During the production process, the strip steel is cut to the required width by cutting. There will be many burrs on the edge of the cut strip steel. The presence of burrs will cause uneven coiling and bending of the strip steel edge when coiling.

[0003] For example, the publication number is CN114559338B, and the name is a cold-rolled strip surface grinding treatment device, which belongs to the field of strip processing technology. The invention includes a base; a conveying platform is fixedly connected at the center of the base; a pair of connecting seats are symmetrically fixedly connected on both sides of the conveying platform on the base, and grinding assemblies for grinding the sides of the strip are rotatably connected on the connecting seats, and the two grinding assemblies are symmetrically arranged on both sides of the conveying platform in an "eight" shape; the grinding assembly includes a connecting plate, and a pair of driven wheels are fixedly connected at both ends of the connecting plate; a driving motor, the driving motor is fixedly connected to the lower surface of the connecting plate, and a driving wheel is fixedly connected to the rotating shaft of the driving motor; a grinding belt, and the grinding belt is rotatably connected to the driving wheel and the driven wheel respectively. The present invention is provided with a pair of grinding assemblies on the base. During grinding, the adjusting assembly brings the grinding assembly into close contact with the two sides of the strip, thereby achieving the purpose of cleaning the burrs on both sides of the strip.

[0004] For example, the publication number is CN114952467A, and the name is an automatic adaptive strip surface grinding and defect detection device and method, including: a truss robot, a strip grinding device, a defect detection device, and an auxiliary device; the strip grinding device, the defect detection device, and the auxiliary device are arranged on the truss robot; the auxiliary device adjusts the bonding state between the strip grinding device and the strip during the grinding process; the grinding track of the strip grinding device is a straight line, and the grinding marks are along the width direction of the strip. The invention improves the bonding state between the oilstone and the strip during the grinding process through the auxiliary roller device, and can adapt to the grinding and defect detection in the case of strip shape problems, and the grinding track of the present invention is a straight line, and the grinding marks are along the width direction of the strip, which meets the strip imaging detection conditions. In the case of overhang, C-warping, etc. in the strip shape, the strip imaging height is the same at different positions through the action of the auxiliary rollers, which ensures the imaging quality and avoids uneven phenomena such as light and dark stripes caused by height.

[0005] There are many burrs and defects on the surface of the steel strip during the production process of cable trays, so the surface of the steel strip needs to be polished when producing cable trays. However, due to the good ductility of the steel strip itself, it is difficult to ensure that both sides of the steel strip are polished evenly during polishing, and it is impossible to ensure the accuracy of the steel strip polishing and the matching of the bending shape of the cable tray. Therefore, the present application provides a steel strip polishing device for cable tray processing to meet the needs. Summary of the invention

[0006] The purpose of the present application is to provide a strip steel grinding device for cable tray processing, which can effectively solve the problems raised in the above-mentioned background technology.

Through the rolling of the pressure wheels, it can be ensured that the strip steel has good flatness before entering the grinding mechanism. The flat strip steel helps the subsequent grinding and bending processes to be smoother and reduce the problems caused by bending or twisting of the strip steel. The upper end of the supporting steel frame is provided with a grinding mechanism for grinding the upper surface of the strip steel, the bottom of the supporting steel frame is provided with a bottom grinding mechanism for grinding the lower surface of the strip steel, the upper end of the supporting steel frame is provided with a protective mechanism for cleaning dust arranged on the outside of the grinding mechanism, a guiding mechanism for guiding the strip steel to enter between the bottom grinding mechanism and the grinding mechanism for grinding is provided on one side of the upper end of the supporting steel frame, and a grinding mark mechanism for producing bending grinding marks on the upper surface of the strip steel is provided on the other side of the upper end of the supporting steel frame.

[0008] Wherein, the guiding mechanism comprises two partitions, an inclined plate is arranged between the two partitions, a roller is rotatably installed between the two partitions and at the lower part of the inclined plate, and the two partitions are fixedly installed on the upper end of the supporting steel frame.

[0012] Among them, the grinding mechanism includes a driving box fixedly installed inside the grinding box frame, a hub is arranged on one side of the driving box, and the outer surface of the hub is provided with a plurality of arc pieces distributed in a ring array, and the outer surfaces of the plurality of arc pieces are jointly sleeved with an outer wheel. The grinding wheel squeezes the strip steel downward to make it present an arc shape. The arc shape helps to disperse stress and reduce stress concentration caused by bending, thereby improving the structural strength of the cable tray. Moreover, by grinding the surface of the strip steel with the grinding wheel, burrs can be effectively removed.

[0013] Wherein, a rubber block is arranged between every two arc pieces, and the arc pieces are made of elastic metal material with good plasticity.

[0014] Among them, a grinding wheel is arranged on the outer surface of the outer wheel, and the grit number of the grinding wheel is the same as that of the grinding belt.

Such double-sided grinding can ensure the high quality of the surface of the steel strip, and the arc shape formed during the grinding process reduces the burrs generated during bending, thereby improving the strength of the finished product. The grinding mark mechanism is specifically used for grinding at the crease, which can effectively remove the burrs generated during the bending process, and the fine grinding of the crease can improve the dimensional accuracy of the cable tray and ensure matching during installation.

[0017] The present invention can ensure that the upper surface of the steel strip is evenly polished through the rotation of the grinding wheel. The larger diameter of the grinding wheel ensures that sufficient pressure is applied to the steel strip during the grinding process, thereby making the grinding effect more uniform. The grinding wheel presses the steel strip downward to make it present an arc shape. The arc shape helps to disperse stress and reduce stress concentration caused by bending, thereby improving the structural strength of the cable tray. In addition, burrs and other surface defects can be effectively removed by grinding the surface of the steel strip with the grinding wheel. The arrangement of the arc sheet and the rubber block can be self-adjusted according to the stress condition of the steel strip. The elastic characteristics of the arc sheet and the rubber block can be deformed accordingly when the stress on the steel strip changes, thereby better adapting to different grinding requirements.

[0018] In the present invention, the grinding mechanism squeezes the steel strip to produce deformation, so that the lower surface of the steel strip is in close contact with the grinding belt of the bottom grinding mechanism, thereby ensuring that the grinding belt can effectively grind the lower surface of the steel strip.

DETAILED DESCRIPTION

[0022] 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.

[0023] Example 1, Reference Figures 1 to 15 A strip steel grinding device for cable bridge processing shown in the figure comprises a grinding box frame 1, a supporting steel frame 7 is arranged inside the grinding box frame 1, pressure wheels 3 are arranged on both sides of the upper end of the supporting steel frame 7, a grinding mechanism 5 for grinding the upper surface of the strip steel is arranged on the upper end of the supporting steel frame 7, a bottom grinding mechanism 8 for grinding the lower surface of the strip steel is arranged at the bottom of the supporting steel frame 7, a protective mechanism 2 for cleaning dust is arranged on the upper end of the supporting steel frame 7, a guiding mechanism 4 for guiding the strip steel to enter between the bottom grinding mechanism 8 and the grinding mechanism 5 for grinding is arranged on one side of the upper end of the supporting steel frame 7, and a grinding mark mechanism 6 for grinding the upper surface of the strip steel to produce bending grinding marks is arranged on the other side of the upper end of the supporting steel frame 7.

[0024] It is worth mentioning that when the strip is ground, the strip is first rolled by the pressure wheel 3 and then fed into the interior of the guide mechanism 4. The guide mechanism 4 is used to guide the strip to be fed between the grinding mechanism 5 and the bottom grinding mechanism 8, and the grinding mechanism 5 grinds the upper surface of the strip. When grinding the strip, the grinding mechanism 5 will also squeeze the strip downward so that the lower surface of the strip contacts the bottom grinding mechanism 8. At this time, the strip ground by the grinding mechanism 5 and the bottom grinding mechanism 8 is in an arc shape. The ground strip is fed into the interior of the grinding mark mechanism 6, and the grinding mark mechanism 6 grinds the fold of the strip into the cable tray. Finally, the dust generated by the grinding mechanism 5 and the bottom grinding mechanism 8 when grinding the strip is adsorbed by the protective mechanism 2.

[0025] Among them, the rolling of the pressure wheel 3 can improve the flatness of the strip, ensuring that the strip can be smoother during subsequent grinding and bending. The rolling process reduces the deformation of the strip in subsequent processing and improves the dimensional accuracy of the finished product. The guiding mechanism 4 can ensure the accurate position of the strip during transportation and avoid deviation, thereby ensuring the consistency and accuracy of grinding.

[0026] The guiding mechanism 4 is able to smoothly guide the steel strip into the grinding area, reducing the stagnation time caused by improper position; the grinding mechanism 5 grinds the upper surface of the steel strip and squeezes the steel strip downward at the same time so that the lower surface of the steel strip contacts the bottom grinding mechanism 8. Such double-sided grinding can ensure the high quality of the surface of the steel strip, and the arc shape formed during the grinding process reduces the burrs generated during bending, thereby improving the strength of the finished product; the grinding mark mechanism 6 is specifically used for grinding at the creases, which can effectively remove the burrs generated during the bending process, and the fine grinding of the creases can improve the dimensional accuracy of the cable tray and ensure matching during installation.

[0027] The guiding mechanism 4 includes two partitions 43 , an inclined plate 41 is arranged between the two partitions 43 , a roller 42 is rotatably installed between the two partitions 43 and at the lower part of the inclined plate 41 , and the two partitions 43 are fixedly installed on the upper end of the supporting steel frame 7 .

[0028] Among them, when the strip steel is rolled by the pressure wheel 3, the flatness of the strip steel can be ensured, and the rolled strip steel is fed into the lower part of the roller 42. As the strip steel moves, the roller 42 is driven to rotate. The set roller 42 squeezes the strip steel to contact the bottom grinding mechanism 8, so that the strip steel can be fed between the grinding mechanism 5 and the bottom grinding mechanism 8.

[0029] Among them, the rolling of the pressure wheel 3 can ensure that the strip has good flatness before entering the grinding mechanism. The flat strip helps the subsequent grinding and bending process to be smoother and reduce the problems caused by bending or twisting of the strip.

[0030] The rotation of the roller 42 helps to guide the steel strip to smoothly enter between the grinding mechanism 5 and the bottom grinding mechanism 8. Since the roller 42 is in contact with the steel strip, it can ensure that the steel strip moves smoothly during the movement and avoid affecting the grinding efficiency due to position deviation.

[0031] Embodiment 2. This embodiment provides a further technical solution for the grinding mechanism 5, bottom grinding mechanism 8, protection mechanism 2 and grinding mechanism 6 according to the grinding mechanism 5, bottom grinding mechanism 8, protection mechanism 2 and grinding mechanism 6 proposed in Embodiment 1.

[0032] The grinding mechanism 5 includes a driving box 51 fixedly mounted inside the grinding box frame 1, a hub 54 is provided on one side of the driving box 51, a plurality of arc pieces 53 distributed in a circular array are provided on the outer surface of the hub 54, and an outer wheel 52 is commonly sleeved on the outer surfaces of the plurality of arc pieces 53.

[0033] The outer surface of the outer wheel 52 is provided with a grinding wheel 56 , and the grinding mesh number of the grinding wheel 56 is the same as that of the grinding belt 85 .

[0034] It is worth mentioning that the steel strip is first fed into the bottom of the grinding wheel 56, and the drive box 51 drives the hub 54 to rotate through the output shaft, and the rotation of the hub 54 drives the arc piece 53 and the outer wheel 52 to rotate. When the outer wheel 52 rotates, it drives the grinding wheel 56 to rotate. When the grinding wheel 56 rotates, it grinds the upper surface of the steel strip. Since the diameter of the grinding wheel 56 is relatively large, it will squeeze the steel strip downward when grinding the steel strip. Since the steel strip has good plasticity, the steel strip is in the shape of an arc when grinding. Since the grinding wheel 56 squeezes the steel strip when grinding the steel strip, the lower surface of the steel strip squeezes the bottom grinding mechanism 8.

[0035] Among them, when grinding the strip steel, the grinding wheel 56 is in close contact with the surface of the strip steel, and the outer wheel 52 squeezes the arc piece 53 after being subjected to force. Since the arc piece 53 is made of elastic metal material with good plasticity, when the arc piece 53 is squeezed and deformed, it squeezes the rubber block 55 set between every two arc pieces 53. The set rubber block 55 is made of hollow rubber, so when the rubber block 55 is squeezed, it will deform and shrink. When the grinding wheel 56 grinds the strip steel, the setting of the arc piece 53 and the rubber block 55 can be adjusted according to the force condition of the strip steel.

[0036] The rotation of the grinding wheel 56 can ensure that the upper surface of the steel strip is evenly ground, and the larger diameter of the grinding wheel 56 ensures that sufficient pressure is applied to the steel strip during the grinding process, thereby making the grinding effect more uniform.

[0037] The grinding wheel 56 presses the strip steel downward to make it present an arc shape. The arc shape helps to disperse stress and reduce stress concentration caused by bending, thereby improving the structural strength of the cable tray. In addition, by grinding the surface of the strip steel with the grinding wheel 56, burrs can be effectively removed. Furthermore, the arrangement of the arc piece 53 and the rubber block 55 can be self-adjusted according to the stress of the steel strip. The elastic characteristics of the arc piece 53 and the rubber block 55 can be deformed accordingly when the stress of the steel strip changes, thereby better adapting to different grinding requirements.

[0038] The bottom grinding mechanism 8 includes a second support frame 83 and a drive motor 81. The second support frame 83 is fixedly mounted on the lower end of the support steel frame 7. Pulleys 82 are arranged on both sides of the second support frame 83. The drive motor 81 is fixedly mounted inside the grinding box frame 1, and the output end of the drive motor 81 is fixedly connected to one of the pulleys 82. A grinding belt 85 is wound around the outer surfaces of the two pulleys 82. An auxiliary wheel 84 for assisting the transmission of the grinding belt 85 is arranged at the bottom of the second support frame 83.

[0039] It is worth mentioning that the grinding mechanism 5 squeezes the steel strip to produce deformation during grinding, and the lower surface of the deformed steel strip contacts the grinding belt 85, and the driving motor 81 drives the pulley 82 to rotate through the output end, and the rotation of the pulley 82 drives the grinding belt 85 to transmit, and the setting of the second support frame 83 and the auxiliary wheel 84 can make the deformed steel strip close to the surface of the grinding belt 85, because the set grinding belt 85 is tensioned on the surfaces of the two pulleys 82 when the steel strip is not grinding, only when the grinding mechanism 5 squeezes the steel strip to deform it and make it close to the surface of the grinding belt 85 can the steel strip be tensioned on the surface of the pulley 82.

[0040] Among them, the grinding mechanism 5 squeezes the steel strip to produce deformation, so that the lower surface of the steel strip is in close contact with the grinding belt 85 of the bottom grinding mechanism 8, thereby ensuring that the grinding belt 85 can effectively grind the lower surface of the steel strip. The close contact between the deformed steel strip and the grinding belt 85 helps to improve the grinding quality and reduce uneven grinding caused by poor contact.

[0041] The provision of the second support frame 83 and the auxiliary wheel 84 helps to ensure that the deformed strip steel can be closely attached to the surface of the grinding belt 85, thereby ensuring the consistency of grinding, reducing the deviation of the strip steel position during the grinding process, and improving the consistency and quality of grinding.

[0042] The protection mechanism 2 includes an outer shield 21 installed on the upper end of the supporting steel frame 7. The outer shield 21 is arranged to cover the outside of the grinding wheel 56, and an exhaust pipe 22 is arranged on one side of the outer shield 21. The exhaust pipe 22 is connected to an external dust reduction device.

[0043] Among them, when the grinding belt 85 and the grinding wheel 56 grind the surface of the strip steel, the dust generated by the grinding is collected inside the outer protective cover 21 and then discharged through the exhaust pipe 22. The exhaust pipe 22 is connected to an external dust reduction device to extract the dust inside the outer protective cover 21, thereby preventing the polished metal powder from polluting the working environment.

[0044] By providing the outer shield 21 and the exhaust pipe 22, the dust generated during the grinding process can be effectively collected and transported to external dust reduction equipment for treatment, thereby greatly reducing the pollution of the dust to the working environment.

[0045] The wear mark mechanism 6 includes a first support frame 63 and a mounting frame 61. The mounting frame 61 and the first support frame 63 are both fixedly mounted on the upper end of the support steel frame 7. A wedge plate 62 is provided on the inner wall of the support steel frame 7 and located at the lower part of the mounting frame 61. A pressure plate 64 is rotatably mounted on the outer surface of the mounting frame 61. Two mounting grooves 67 are symmetrically provided inside the pressure plate 64. A grinding rod 65 is provided inside the two mounting grooves 67. A rectangular groove 69 is provided on one side of the two grinding rods 65. A pin 66 that passes through the rectangular groove 69 is provided inside the pressure plate 64. A spring 68 is provided at the upper end of the pressure plate 64, and one end of the spring 68 is fixedly connected to the first support frame 63.

[0046] The pressing plate 64 is located on the upper portion of the wedge-shaped plate 62 , and the outer surface of the grinding rod 65 is provided with a grinding sheet.

[0047] It is worth mentioning that after the steel strip is polished by the polishing belt 85 and the polishing wheel 56, the polished steel strip is sent between the wedge plate 62 and the pressure plate 64. When the steel strip moves, the grinding rod 65 rubs against the upper surface of the steel strip, and the spring 68 squeezes the pressure plate 64 to contact the upper surface of the steel strip. The setting of the spring 68 enables the grinding rod 65 to be tightly attached to the surface of the steel strip and adjusted. The user can also unplug the pin 66 to remove the grinding rod 65 from the mounting slot 67 to replace the grinding rod 65 with different mesh sizes.

[0048] Among them, the grinding rod 65 further grinds the upper surface of the strip, which helps to remove burrs and other surface defects that may be generated during the bending process. The setting of the spring 68 enables the grinding rod 65 to be adaptively adjusted according to the thickness and surface condition of the strip, ensuring that the appropriate contact pressure is always maintained during the grinding process.

[0049] Working principle: When grinding the strip, the strip is first rolled by the pressing wheel 3. The rolling of the pressing wheel 3 can improve the flatness of the strip, ensuring that the strip can be flatter during the subsequent grinding and bending process. The rolling process reduces the deformation of the strip in the subsequent processing and improves the dimensional accuracy of the finished product. The guiding mechanism 4 can ensure that the strip is accurately positioned during the conveying process to avoid deviation, thereby ensuring the consistency and accuracy of grinding; Then it is sent to the interior of the guiding mechanism 4, which is used to guide the strip steel to be sent between the grinding mechanism 5 and the bottom grinding mechanism 8, and the grinding mechanism 5 grinds the upper surface of the strip steel. When grinding the strip steel, the grinding mechanism 5 will also squeeze the strip steel downward so that the lower surface of the strip steel contacts the bottom grinding mechanism 8. At this time, the strip steel grinded by the grinding mechanism 5 and the bottom grinding mechanism 8 is in an arc shape, and the grinded strip steel is sent to the interior of the grinding mark mechanism 6, and the grinding mark mechanism 6 is used to grind the fold of the strip steel bent into the cable tray. Finally, the dust generated when the grinding mechanism 5 and the bottom grinding mechanism 8 grind the strip steel is adsorbed by the protective mechanism 2.

[0050] The guiding mechanism 4 provided therein can smoothly guide the strip into the grinding area, reducing the stagnation time caused by improper position. The grinding mechanism 5 grinds the upper surface of the strip and squeezes the strip downward at the same time so that the lower surface of the strip contacts with the bottom grinding mechanism 8. Such double-sided grinding can ensure the high quality of the strip surface, and the arc shape formed during the grinding process reduces the burrs generated during bending, thereby improving the strength of the finished product. The grinding mark mechanism 6 is specifically used for grinding at the creases, which can effectively remove the burrs generated during the bending process, and the fine grinding of the creases can improve the dimensional accuracy of the cable tray and ensure matching during installation.

[0051] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
