Description

Technical Field

[0001] The present invention relates to the field of metal processing, and particularly to a stainless steel strip deburring and shearing machine. Background Art

[0002] Stainless steel strips are formed by cold rolling or hot rolling of carbon alloys. Stainless steel strips, like raw materials for metal products, are widely used in civil hardware, light industry, non-ferrous metals and other fields. After the steel strips are rolled and formed, it is necessary to cut the two edges of the strips. The purpose of cutting is to make the two edges of the steel strips neat and facilitate subsequent winding and packing.

[0003] After the two edges of the steel strip are cut by the commonly used shearing machine on the market, the cut of the steel strip will be deformed. The deformed position at the edge of the steel strip is similar to a small raised structure. If the cutting edge of the shearing machine is worn, this small raised structure will generate fine burrs. Whether it is the raised edge cut or the burrs, they are all relatively sharp. When workers wind and pack the steel strip, they often scratch their gloves and cause hand injuries.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1 - 3 , a burr-removing and shearing machine for stainless steel strips shown in the figure, includes: a workbench surface, and a slide rail frame 1, a shearing machine table 2, a first conveyor table 3, and a second conveyor table 4 fixedly installed on the workbench surface. The first conveyor table 3 and the second conveyor table 4 are used to convey the steel strip. The shearing machine table 2 cuts the side edges of the conveyed steel strip. The slide rail frame 1 is located between the shearing machine table 2 and the second conveyor table 4, and the first conveyor table 3 is located on the side of the shearing machine table 2 away from the slide rail frame 1. Two symmetrically distributed sliding blocks 5 are slidably installed inside the slide rail frame 1. An oppositely threaded screw rod 6 is rotatably arranged inside the slide rail frame 1, and the two sliding blocks 5 are threadedly sleeved outside the oppositely threaded screw rod 6. The first conveyor table 3 and the second conveyor table 4 are common conveying structures in the prior art, mainly used to horizontally convey the steel strip, and the shearing machine table 2 is also a shearing structure in the prior art, used to cut and process the burrs on both sides of the conveyed steel strip;

[0031] It further includes: a grinding unit for grinding the side edges of the cut steel strip, and the grinding unit is located at the bottom of the sliding block 5;

[0032] A cooling unit for cooling and lowering the temperature of the contact part between the grinding unit and the steel strip;

[0033] A cleaning unit for cleaning the sludge generated by grinding the side edges of the steel strip;

[0034] The grinding unit, the cooling unit, and the cleaning unit are synchronously driven to operate.

[0035] The grinding unit is located on the frame 7 assembled under each sliding block 5, and the frame 7 moves with the sliding block 5. A motor 8 is fixedly installed inside each frame 7. Two symmetrically distributed first rotating shafts 9 are rotatably assembled on the end faces of the two frames 7 close to each other, and the two first rotating shafts 9 are symmetrically arranged up and down. Two symmetrically distributed movable arms 11 are rotatably sleeved on the outer surface of each first rotating shaft 9. The other ends of the two movable arms 11 distributed outside the same first rotating shaft 9 are jointly rotatably assembled with a second rotating shaft 10. A grinding roller 12 is fixedly sleeved on the outer surface of each second rotating shaft 10. A first spring 13 is fixedly installed between each movable arm 11 and the frame 7. Tooth discs 36 are fixedly sleeved on the outer surfaces of the two first rotating shafts 9 on the same side, and the two tooth discs 36 are meshed with each other. A second synchronous belt group 15 is transmission-assembled between the first rotating shaft 9 and the second rotating shaft 10 assembled on the same movable arm 11. A first synchronous belt group 14 is transmission-assembled between the output end of the motor 8 and the end of one of the first rotating shafts 9. Under the action of the first spring 13, the two grinding rollers 12 symmetrically distributed up and down can be brought into contact with each other. Moreover, through the action of the two meshed tooth discs 36, the two grinding rollers 12 can rotate synchronously and in opposite directions.

[0036] Working principle: The steel belt is conveyed by the first conveyor table 3 and the second conveyor table 4 in the prior art, and the side of the steel belt is cut by the shearing machine table 2 in the prior art. Before the cutting process, the staff needs to adjust the positions of the two groups of grinding rollers 12, that is, by rotating the non-unidirectional threaded rod 6, the two sliding blocks 5 drive the two frames 7 to move synchronously and in opposite directions. During the movement, the two groups of grinding rollers 12 can clamp and process the cut side of the steel belt. Since the grinding rollers 12 symmetrically distributed downward have a certain elastic pressure under the action of the first spring 13, that is, when the frame 7 moves towards the steel belt, the grinding rollers 12 can be pressed against the side edge of the steel belt. Then, the motor 8 can be started. The motor 8 can make the two first rotating shafts 9 drive the two second rotating shafts 10 to rotate synchronously through the first synchronous belt group 14 and the two meshed tooth discs 36. The rotation directions of the two grinding rollers 12 distributed up and down are opposite. During the rotation of the grinding rollers 12, the edges of the steel belt with the cut side during the conveying process can be ground. The edges of the steel belt after grinding are in the shape of smooth arc angles, and the sharp edges and small burrs caused by the cutting of the steel belt can be completely ground off, which can avoid the situation that the staff's hands are scratched by burrs or cutting end faces when winding and transporting the steel belt, and improve the safety of the steel belt winding and transporting operation.

[0037] Embodiment 2: Please refer to Figure 4 and Figure 5, This embodiment is a further illustration of Embodiment 1. The cooling unit includes a sealing cylinder 16 fixedly installed at the bottom of the frame 7. One end of the sealing cylinder 16 is fixedly and communicatively connected with a first delivery pipe 17, and a second delivery pipe 18 is also fixedly and communicatively connected to the side wall of the sealing cylinder 16. A piston disk 19 is slidably fitted inside the sealing cylinder 16, and a second spring 20 is provided at one end of the piston disk 19 close to the first delivery pipe 17. The second delivery pipe 18 extends upward towards the motor 8, and the end of the second delivery pipe 18 away from the sealing cylinder 16 is fixedly butt-connected with a nozzle, and the nozzle faces the grinding roller 12. First check valves and second check valves are also assembled outside the first delivery pipe 17 and the second delivery pipe 18. A triggering component is also provided outside the sealing cylinder 16. When the motor 8 is started, the triggering component can also be started, so that the piston disk 19 reciprocates inside the sealing cylinder 16, and the coolant inside it is sprayed onto the grinding roller 12 through the nozzle.

[0038] The triggering component includes a turntable 23 fixedly sleeved on the end of one of the first rotating shafts 9, and at least two arc-shaped lifting blocks 24 arranged at equal circumferential intervals are fixedly provided on the end face of the turntable 23 facing the frame 7. A curved rod 21 is fixedly provided at one end of the piston disk 19 away from the second spring 20, and the curved rod 21 slidably penetrates through the sealing cylinder 16. A spherical block 22 is fixedly provided at the end of the curved rod 21 away from the piston disk 19, and the spherical block 22 is in movable contact with the inclined surface of the arc-shaped lifting block 24. When the turntable 23 and the arc-shaped lifting block 24 rotate, the curved rod 21 can be pushed through the spherical block 22, and under the action of the second spring 20, the reciprocating movement of the piston disk 19 can be realized.

[0039] The flow direction of the first check valve is unidirectional flow from the first delivery pipe 17 to the sealing cylinder 16, and the flow direction of the second check valve is unidirectional flow from the sealing cylinder 16 to the second delivery pipe 18. The first check valve and the second check valve play a role in restricting the fluid flow direction.

[0040] In this embodiment: In this solution, considering the long-term contact friction between the grinding roller 12 and the steel strip, the temperature of the grinding roller 12 will rise, affecting the service life of the grinding roller 12. Therefore, in this solution, when the motor 8 is starting up, the first rotating shaft 9 can drive the arc-shaped lifting block 24 to rotate through the turntable 23. During the rotation, the arc-shaped lifting block 24 can intermittently push the curved rod 21 through the spherical block 22. With the cooperation of the second spring 20, the reciprocating movement of the piston disk 19 inside the sealing cylinder 16 can be realized. The coolant can be replenished from the outside into the sealing cylinder 16 through the first delivery pipe 17, and then output through the second delivery pipe 18 and sprayed onto the grinding roller 12 through the nozzle, so as to cool down the grinding roller 12 and avoid the problem that the grinding roller 12 is easily damaged due to excessive temperature.

[0041] Embodiment 3: Please refer to Figure 6 andFigure 7 , this embodiment is a further illustration of Embodiment 2. The cleaning unit includes a cleaning frame body 25 fixedly installed at one end of the frame 7 away from the shearing machine table 2. One end of a first rotating shaft 9 close to the cleaning frame body 25 is assembled with an extension shaft 26 through a coupling, and the extension shaft 26 is rotatably fitted inside the cleaning frame body 25. At least two groups of cleaning components are arranged inside the cleaning frame body 25, and the cleaning components are driven to operate by the extension shaft 26. The extension shaft 26 can rotate inside the cleaning frame body 25 following the first rotating shaft 9.

[0042] The cleaning components include a first transmission shaft 29 and a second transmission shaft 30 rotatably fitted inside the cleaning frame body 25. The first transmission shaft 29 and the second transmission shaft 30 are both vertically distributed with respect to the extension shaft 26, and the extension shaft 26 is located between the first transmission shaft 29 and the second transmission shaft 30. A cleaning wheel 31 for wiping the sludge on the side of the steel belt is fixedly sleeved on the outer surface of the second transmission shaft 30. A third synchronous pulley belt group 32 is transmission-assembled between the first transmission shaft 29 and the second transmission shaft 30. A worm 27 is fixedly sleeved on the outer surface of the extension shaft 26, and a first worm gear 28 meshing with the worm 27 is fixedly sleeved on the outer surface of the first transmission shaft 29. Through the meshing of the worm 27 and the first worm gear 28 and the action of the third synchronous pulley belt group 32, the second transmission shaft 30 can be made to drive the cleaning wheel 31 to rotate.

[0043] The cleaning wheel 31 is made of a flexible material and is a V-shaped wheel. A brush member for cleaning the impurities attached to the surface of the cleaning wheel 31 is also arranged inside the cleaning frame body 25. The material of the cleaning wheel 31 can be sponge, flexible cloth, etc. The V-shaped cleaning wheel 31 can have a certain degree of wrapping around the side of the steel belt, thereby improving the cleaning effect.

[0044] The brush member includes a second worm gear 34 located on the side of the worm 27 away from the first worm gear 28, and the second worm gear 34 also meshes with the worm 27. A third transmission shaft 33 rotatably embedded inside the cleaning frame body 25 is fixedly arranged inside the second worm gear 34, and a brush wheel 35 for cleaning the surface of the cleaning wheel 31 is fixedly sleeved on the outer surface of the third transmission shaft 33. The sludge on the side of the steel belt is a mixture of polished metal powder and coolant.

[0045] The outer surface of the brush wheel 35 is tangent to the outer surface of the cleaning wheel 31, and the metal powder adhered to the surface of the cleaning wheel 31 can be brushed off by the bristles of the brush wheel 35.

[0046] In this embodiment, during the grinding process of the edge of the steel strip by the grinding roller 12 sprayed with the coolant, mud and dirt will be generated. The components of the mud and dirt are a mixture of the machining grease originally on the surface of the steel strip, the metal powder debris generated by grinding, and the coolant. This mud and dirt will adhere to the side of the steel strip during transportation, which will cause the mud and dirt to easily adhere to the clothes of the staff during the later winding and handling of the steel strip, and it is difficult to clean. Therefore, in this solution:

[0047] During the continuous transportation of the ground steel strip, the first rotating shaft 9 can drive the extension shaft 26 to rotate. The worm 27 sleeved on the surface of the extension shaft 26 can drive the first worm gear 28 and the second worm gear 34 to transmit at the same time, so that the cleaning wheel 31 and the brush wheel 35 can rotate at the same time. The cleaning wheel 31 can wipe and absorb the mud and dirt adhering to the surface of the edge of the steel strip to ensure the cleanliness of the edge of the steel strip;

[0048] Since the brush wheel 35 is driven by the second worm gear 34 and the cleaning wheel 31 is driven by the first worm gear 28, and the first worm gear 28 and the second worm gear 34 are respectively assembled on both sides of the worm 27, the rotation directions of the two are opposite. After the cleaning wheel 31 wipes and absorbs the mud and dirt, the metal debris or metal powder on its surface can be cleaned by the bristles on the surface of the brush wheel 35. The bristles on the surface of the brush wheel 35 are made of nylon material.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
