Description

Technical Field

[0001] The present invention belongs to the technical field of steel strip edge trimming, and specifically relates to a cold-rolled steel strip edge trimming device. Background Art

[0002] After cold rolling, surplus edge materials will be generated at both sides of the steel strip, which macroscopically appear rough. For the quality requirements of the steel strip, edge trimming equipment is usually used to trim the two sides of the steel strip.

[0003] Currently, when the traditional steel strip edge trimming device trims the cold-rolled steel strip, the steel strip coil is usually installed on a placement rack on one side of the edge trimming device. At the same time, the steel strip on the steel strip coil is pulled out and installed with the winding equipment on one side of the edge trimming device, so that the steel strip passes between the inner cavities of the edge trimming device, and then the steel strip is wound by the traction of the winding equipment. When the steel strip is pulled through the inner cavities of the edge trimming device, the surplus edge of the steel strip can contact the cutting tool, and then the cutting tool is used to cut off the surplus edge.

[0004] In the actual application of the above solution, since the steel strip is wound and moved by the traction of an external winding device, and at the same time, the steel strip passes between the inner cavities of the edge trimming device, and the edge trimming device is used to limit both sides of the steel strip to prevent the steel strip from running off during the winding process. Moreover, the edge trimming device will also drive the cutting tool to fit with both sides of the steel strip. If there are surplus edges on the steel strip, the cutting tool will be used to cut and repair the surplus edges on both sides of the steel strip. However, there are still some problems. Since the cutting tool is fixed, and during the process of pulling the steel strip by the winding equipment, the surplus edge of the steel strip contacts the cutting tool to achieve edge trimming. If the cutting tool cannot cut off all the surplus edges of the steel strip at once, it will cause the cutting tool to pull the surplus edge and tear the entire steel strip, resulting in the problem of steel strip tearing. Moreover, after cutting off the surplus edges, a large amount of burrs will also be generated on both sides of the steel strip edge trimming. If the burrs are not polished off, it will also affect the quality of the steel strip.

[0005] Therefore, the present invention provides a cold-rolled steel strip edge trimming device. Summary of the Invention

Two semi-circular grinding pieces are arranged outside the rotating block.

[0010] Preferably, a micro spring is fixedly connected to the bottom of the inner cavity of the receiving groove. One end of the micro spring is fixedly connected to an I-shaped sliding column. One end of the I-shaped sliding column is fixedly connected to the semi-circular grinding piece. A T-shaped sliding column is fixedly connected to the upper end of the rotating block, and the T-shaped sliding column is slidably connected to the first clamping plate.

[0011] Preferably, two first springs are symmetrically and fixedly connected to the lower end surface of the second clamping plate, and one end of each of the two first springs is fixedly connected to the T-shaped sliding rod.

[0012] Preferably, two rotating disks are symmetrically and rotatably connected to one side of the inner cavity of the through groove. A plurality of tooth blocks are arranged outside the two rotating disks, and the tooth blocks outside the two rotating disks are arranged in a staggered manner. Grinding pieces are annularly arranged outside the cutting and pressing wheels.

[0013] Preferably, four fixing sleeves are symmetrically and fixedly connected to both ends of the first clamping plate and the second clamping plate. A rotating column is rotatably connected to the inner cavity of the four fixing sleeves. A rubber cushion layer is arranged outside the rotating column.

[0014] Preferably, four grooves are formed on the inner wall of the collection chamber. Fixed columns are fixedly connected to the inner cavities of the four grooves. Limiting blocks are slidably connected to the outside of the fixed columns. A pressing plate is fixedly connected between the limiting blocks.

[0015] Preferably, a fluff brush is arranged on the lower end surface of the pressing plate. Second springs are fixedly connected to the upper ends of the limiting blocks, and the second springs are fixedly connected to the inner walls of the grooves. Fluff brushes are arranged on both sides of the upper end of the main body of the trimming device.

[0016] Preferably, two fixing rods are symmetrically and fixedly connected to both ends of the main body of the edge trimming device.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For the cold-rolled steel belt edge trimming device of the present invention, the steel belt is installed between the first clamping plate and the second clamping plate, and then the external winding equipment is used to traction the steel belt for winding. During the process of traction the steel belt to move, if there are redundant edges and corners on both sides of the steel belt, they will slide between the cutting and pressing wheels, and the cutting and pressing wheels are used to roll-press the redundant edges and corners on both sides of the steel belt. After rolling and pressing the cutting marks on the redundant edges and corners on both sides of the steel belt, as the steel belt moves with the traction of the external winding equipment, the cutting knife will cut the redundant edges and corners on both sides of the steel belt along the rolled cutting marks. At the same time, the grinding blocks between the cutting knives are used to grind and repair the redundant edges and corners cut off from the steel belt, thus solving the problem that when the existing cold-rolled steel belt edge trimming device trims the redundant edges and corners on both sides of the steel belt, during the process of winding and moving the steel belt by the external winding equipment, the steel belt passes between the edge trimming equipment, and then the cutting knife is used to cut and repair the redundant edges and corners of the steel belt. However, since the cutting knife is fixed and the redundant edges and corners of the steel belt come into contact with the cutting knife during the process of traction the steel belt by the winding equipment to achieve edge trimming. If the cutting knife cannot cut off all the redundant edges and corners of the steel belt at once, it will cause the cutting knife to pull the redundant edges and corners and tear the whole steel belt, resulting in the problem of steel belt tearing.

[0020] 2. In the cold-rolled steel strip trimming device of the present invention, during the movement of the steel strip between the first clamping plate and the second clamping plate, the excess corners on both sides of the steel strip will slide into the space between the trimming wheels of the first clamping plate and the second clamping plate. Then, the trimming wheels are used to roll-press the excess corners on both sides of the steel strip. At the same time, the grinding sheets arranged in a ring shape outside the trimming wheels are used to grind both sides of the steel strip, thereby shaping both sides of the steel strip. After the excess corners on both sides of the steel strip move between the rotating disks, the tooth blocks outside the rotating disks are used to cut holes in the impressions rolled out, so as to facilitate the cutting knife to cut along the rolled-out impressions, improving the efficiency of steel strip trimming and preventing the cutting knife from being unable to cut off all the excess corners of the steel strip at once, resulting in the cutting knife pulling the excess corners and tearing the entire steel strip, causing the problem of steel strip tearing.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Embodiment:

[0035] As Figures 1 to 8 shown, a cold-rolled steel strip edge trimming device described in an embodiment of the present invention includes an edge trimming device main body 1. A collection cavity 33 is opened at the upper end of the edge trimming device main body 1, and a collection rack 28 is slidably connected to the bottom of the inner cavity of the collection cavity 33. A steel strip width adjustment assembly is arranged in the inner cavity of the collection cavity 33;

[0036] And the steel strip width adjustment assembly includes a fixed frame 5 fixedly connected to the inner wall of the collection cavity 33. A bidirectional threaded rod 12 is rotatably connected to the inner cavity of the fixed frame 5. One end of the bidirectional threaded rod 12 penetrates through the edge trimming device main body 1 and is fixedly connected with a crank 2. Two T-shaped sliders 13 are threadedly connected to the outside of the bidirectional threaded rod 12. Second clamping plates 24 are fixedly connected to the upper ends of the two T-shaped sliders 13. T-shaped sliding rods 26 are slidably connected to both sides of the upper end surfaces of the second clamping plates 24. First clamping plates 6 are fixedly connected to the upper ends of the T-shaped sliding rods 26. Through grooves 7 are opened between the first clamping plates 6 and the second clamping plates 24. A plurality of cutting and pressing wheels 8 are rotatably connected to the inner cavities of the through grooves 7, and the plurality of cutting and pressing wheels 8 are symmetrically arranged. A cutting tool 23 is installed inside the upper end of the second clamping plate 24, and the cutting tool 23 is slidably connected to the first clamping plate 6.

[0037] Specifically, in the prior art, the steel strip is pulled and wound by an external winding device. At the same time, the steel strip passes between the edge trimming devices, and the edge trimming devices are used to limit both sides of the steel strip to prevent the steel strip from running off during the winding process. Then, the edge trimming device drives the cutting tool to fit with both sides of the steel strip. If there are excess corners on the steel strip, the cutting tool will be used to cut and repair the excess corners on both sides of the steel strip. However, since the cutting tool is stationary, and during the process of pulling the steel strip by the winding device, the excess corners of the steel strip come into contact with the cutting tool to achieve edge trimming. If the cutting tool cannot cut off all the excess corners of the steel strip at once, it will cause the cutting tool to pull the excess corners and tear the entire steel strip, resulting in the problem of steel strip tearing.

[0038] In the present invention, one end of the steel strip is passed through the collection chamber 33 and installed between the first clamping plate 6 and the second clamping plate 24. Then, an external winding device is used to pull and wind the steel strip. During the process of pulling the steel strip by the external winding device, if there are excess corners on both sides of the steel strip, they will slide between the cutting and pressing wheels 8, and the cutting and pressing wheels 8 are used to roll press the excess corners on both sides of the steel strip. There are multiple cutting and pressing wheels 8, and they are symmetrically arranged. Therefore, multiple cutting and pressing wheels 8 can be used to roll press the excess corners on both sides of the steel strip multiple times, making the rolled imprints deeper and thinner, thereby improving the stability and safety during the edge trimming of the steel pipe. After rolling imprints for cutting are made on the excess corners on both sides of the steel strip, as the steel strip moves under the traction of the external winding device, the cutting tool 23 will cut the excess corners on both sides of the steel strip along the rolled cutting imprints. At the same time, the grinding blocks between the cutting tools 23 are used to grind and repair the areas where the excess corners of the steel strip are cut off, ensuring the flatness of both sides of the steel strip. Thus, it solves the problem that in the prior art cold-rolled steel strip edge trimming device, during the process of pulling and winding the steel strip by the external winding device, the steel strip passes between the edge trimming devices, and then the cutting tool is used to cut and repair the excess corners of the steel strip. However, since the cutting tool is stationary, and during the process of pulling the steel strip by the winding device, the excess corners of the steel strip come into contact with the cutting tool to achieve edge trimming. If the cutting tool cannot cut off all the excess corners of the steel strip at once, it will cause the cutting tool to pull the excess corners and tear the entire steel strip, resulting in the problem of steel strip tearing.

[0039] When trimming steel strips of different widths, by driving the crank 2 to rotate, the bidirectional threaded rod 12 is driven to rotate at the same time. During the rotation of the bidirectional threaded rod 12, the two T-shaped sliders 13 are thread-driven to move closer to each other in the inner cavity of the fixed frame 5. Then, the T-shaped sliders 13 drive the second clamping plate 24 to move synchronously, and at the same time, the second clamping plate 24 drives the first clamping plate 6 to move, so as to facilitate adjustment according to the width of the steel strip, so that the first clamping plate 6 and the second clamping plate 24 can clamp and limit the steel strip, improving the practicability of the cold-rolled steel strip trimming device, and solving the problem that when the existing cold-rolled steel strip trimming device trims steel strips of different widths, it is difficult to trim steel strips of different widths because it is inconvenient to adjust the distance of the trimming device according to the width of different steel strips.

[0040] As Figure 1 and Figure 7 shown, a plurality of rotating grooves are formed on the upper end surface of the second clamping plate 24, and rotating blocks 18 are rotatably connected to the inner cavities of the plurality of rotating grooves. Two sets of receiving grooves 19 are symmetrically arranged on both sides of the rotating block 18, and each set of receiving grooves 19 is composed of two receiving grooves 19. Two semi-circular grinding sheets 22 are arranged outside the rotating block 18.

[0041] Specifically, after the redundant corners of the steel strip are cut off, as the external winding device pulls the steel strip to wind and move, the two sides of the steel strip can be polished by the semi-circular grinding sheets 22, preventing a large number of burrs from being generated after the redundant corners on both sides of the steel strip are cut off because it is inconvenient to polish both sides of the steel strip, which affects the quality of the steel strip. At the same time, the semi-circular grinding sheets 22 can also polish and repair both sides of the steel strip, improving the quality of the steel strip.

[0042] As Figure 1 and Figure 3 shown, a micro spring 20 is fixedly connected to the bottom of the inner cavity of the receiving groove 19. One end of the micro spring 20 is fixedly connected to a T-shaped sliding column 21, and one end of the T-shaped sliding column 21 is fixedly connected to the semi-circular grinding sheet 22. A T-shaped sliding column 17 is fixedly connected to the upper end of the rotating block 18, and the T-shaped sliding column 17 is slidably connected to the first clamping plate 6.

[0043] Specifically, after the redundant edges and corners of the steel strip are cut off, as the external winding device pulls the steel strip to wind and move, when the steel strip moves to the rotating block 18, the I-shaped sliding column 21 is bounced by the micro spring 20 in the inner cavity of the receiving groove 19, and the I-shaped sliding column 21 slides out of the inner cavity of the receiving groove 19. At the same time, the I-shaped sliding column 21 pushes the semi-circular grinding piece 22 to fit with both sides of the steel strip. Then, as the winding device pulls the steel strip to wind and move, the semi-circular grinding piece 22 is used to grind both sides of the steel strip, preventing a large number of burrs from being generated after the redundant edges and corners on both sides of the steel strip are cut off, which would affect the quality of the steel strip due to the inconvenience of grinding both sides of the steel strip. Thus, the problem that a large number of burrs are generated after the redundant edges and corners on both sides of the existing cold-rolled steel strip trimming device are cut off, and if not ground, the large number of burrs will affect the quality of the steel strip and pose a safety hazard to the operators is solved.

[0044] As Figure 1 and Figure 7 shown, two first springs 27 are symmetrically fixedly connected to the lower end face of the second clamping plate 24, and one end of each of the two first springs 27 is fixedly connected to the T-shaped sliding rod 26.

[0045] As Figure 1 and Figure 7 shown, two rotating disks 25 are symmetrically rotatably connected to one side of the inner cavity of the through groove 7, and a plurality of tooth blocks 34 are arranged on the outside of each of the two rotating disks 25, and the tooth blocks 34 on the outside of the two rotating disks 25 are arranged in a staggered manner. A grinding piece 35 is annularly arranged on the outside of the cutting and pressing wheel 8.

[0046] Specifically, during the movement of the steel strip between the first clamping plate 6 and the second clamping plate 24, the first spring 27 bounces to push the T-shaped sliding rod 26, and the T-shaped sliding rod 26 is slidably connected inside the second clamping plate 24. At the same time, the first clamping plate 6 is pulled downward, so that the first clamping plate 6 drives the cutting and pressing wheel 8 to contact the cutting and pressing wheel 8 of the second clamping plate 24. When there are redundant edges and corners on both sides of the steel strip, the redundant edges and corners on both sides of the steel strip will slide into the space between the cutting and pressing wheels 8 of the first clamping plate 6 and the second clamping plate 24. Then, the cutting and pressing wheel 8 is used to roll-press the redundant edges and corners on both sides of the steel strip, and at the same time, the grinding piece 35 annularly arranged on the outside of the cutting and pressing wheel 8 is used to grind both sides of the steel strip, thereby shaping both sides of the steel strip. After the redundant edges and corners on both sides of the steel strip move between the rotating disks 25, the tooth blocks 34 on the outside of the rotating disks 25 are used to cut holes in the indentations rolled out, so as to facilitate the cutting knife 23 to cut along the rolled-out indentations, improve the efficiency of steel strip edge trimming, and prevent the cutting knife from being unable to cut off all the redundant edges and corners of the steel strip at once, resulting in the cutting knife pulling the redundant edges and corners to tear the entire steel strip, causing the problem of steel strip tearing.

[0047] As Figure 1 and Figure 4As shown, four fixing sleeves 9 are symmetrically and fixedly connected to both ends of the first clamping plate 6 and the second clamping plate 24, and a rotating column 10 is rotatably connected to the inner cavity of the four fixing sleeves 9. A rubber cushion layer is arranged outside the rotating column 10.

[0048] Specifically, when trimming steel strips of different widths, the distance is adjusted by driving the two second clamping plates 24 to move closer to each other. At the same time, the two second clamping plates 24 drive the first clamping plate 6 to move synchronously, so as to adjust according to steel strips of different widths. During the process of the second clamping plate 24 driving the first clamping plate 6 to move closer to each other, the second clamping plate 24 and the first clamping plate 6 will drive the fixing sleeve 9 to slide outside the rotating column 10 to adjust the distance. Then, the steel strip is clamped by the rotating column 10, and a rubber cushion layer is arranged outside the rotating column 10. Thus, during the movement of the steel strip, the rotating column 10 is used to assist in rolling, ensuring the flatness of the surface of the steel strip, and then improving the efficiency and accuracy of steel strip trimming.

[0049] Embodiment:

[0050] As Figure 4 and Figure 6 shown, four grooves 29 are formed in the inner wall of the collection cavity 33, and fixing columns 30 are fixedly connected to the inner cavities of the four grooves 29. A limiting block 32 is slidably connected to the outside of the fixing column 30, and a pressing plate 11 is fixedly connected between the limiting blocks 32.

[0051] As Figure 4 and Figure 6 shown, a fluff brush is arranged on the lower end surface of the pressing plate 11. A second spring 31 is fixedly connected to the upper end of the limiting block 32, and the second spring 31 is fixedly connected to the inner wall of the groove 29. Fluff brushes are arranged on both sides of the upper end of the trimming device main body 1.

[0052] Specifically, when the external winding device pulls the steel strip for winding and moving, the steel strip passes between the pressing plate 11 and the trimming device main body 1. At the same time, the second spring 31 in the inner cavity of the groove is used to bounce the limiting block 32 to move downward, and the limiting block 32 slides downward outside the fixing column 30, then drives the pressing plate 11 to move downward. Fluff brushes are arranged between the pressing plate 11 and the trimming device main body 1. Thus, when the steel strip passes between the pressing plate 11 and the trimming device main body 1, the pressing plate 11 is used in cooperation with the trimming device main body 1 to flatten the steel strip, preventing the uneven steel strip from affecting the trimming device for trimming the excess edges and corners of the steel strip. At the same time, the waste chips and dust on the surface of the steel strip are cleaned, thus solving the problem that in the process of pulling the steel strip for winding and moving by the existing cold-rolled steel strip trimming device, since a large amount of iron chips will be generated on the surface of the steel strip before production and processing, if not cleaned, the iron chips will lift the rotating column, affecting the rolling marks of the trimming device on the excess edges and corners of the steel strip and affecting the trimming efficiency.

[0053] As Figure 1 、Figure 2 and Figure 8 As shown in Figure 8 , two fixing rods 3 are symmetrically and fixedly connected to both ends of the trimming device body 1. One end of the trimming device body 1 is rotatably connected to a driving sprocket 14. A chain 15 is externally connected to the driving sprocket 14. Both ends of the chain 15 are connected to two driven sprockets 16 in a driving manner, and the two driven sprockets 16 are rotatably connected to the fixing rods 3. One end of the driven sprocket 16 penetrates through the fixing rod 3 and is fixedly connected to a steel belt winding and unwinding assembly 4.

[0054] As Figure 1 and Figure 8 shown in Figure 8 , the steel belt winding and unwinding assembly 4 includes a transmission column 41 rotatably connected inside the fixing rod 3. A limiting chute 42 is opened inside the transmission column 41. A bidirectional lead screw 43 is rotatably connected to the inner cavity of the limiting chute 42. Two sliding disks 44 are externally threaded to the bidirectional lead screw 43. Two push rods 45 are rotatably connected to the outside of the two sliding disks 44, and one end of the push rod 45 is rotatably connected to a clamping rod 46.

[0055] Specifically, when trimming the steel belt, by placing the steel belt roll outside the transmission column 41, simultaneously driving the bidirectional lead screw 43 to rotate, then the bidirectional lead screw 43 thread - drives the two sliding disks 44 to move closer to each other, and the sliding disks 44 drive the push rods 45 to move synchronously. At the same time, the push rods 45 push the clamping rods 46 to slide out from the inner cavity of the limiting chute 42, so that the clamping rods 46 expand and squeeze the steel belt roll to be fixed outside the transmission column 41. Then, the steel belt is pulled out from the outside of the steel belt roll, and the steel belt passes through the collection cavity 33 and contacts another transmission column 41. At the same time, the clamping rods 46 are used to drive the steel belt to be clamped and fixed with the transmission column 41. Then, the driving motor is used to drive the driving sprocket 14 to rotate, and the driving sprocket 14 drives the chain 15 to rotate. At the same time, the chain 15 drives the driven sprockets 16 to rotate. During the rotation of the driven sprockets 16, the two transmission columns 41 will be driven to rotate. Thus, the transmission column 41 drives the steel belt to be wound, and the transmission column 41 on the right side of the trimming device body 1 drives the steel belt roll to discharge the steel belt. As a result, the steel belt passes between the trimming devices, and then the trimming devices are used to trim the excess edges and corners of the steel belt. The excess edges and corners cut from both sides of the steel belt will directly fall into the collection cavity 33, and then the collection frame 28 is used to collect and process the waste generated by the steel belt trimming, thus solving the problem that in the existing cold - rolled steel belt trimming device, when trimming the steel belt, due to the inconvenient control of the discharging and winding speed of the steel belt, the discharging and winding speed of the steel belt is too fast, and the cutting knife is fixed, resulting in the cutting knife being unable to cut off the excess edges and corners of the steel pipe at once, causing the cutting knife to pull the excess edges and corners and tear the whole steel belt, resulting in the steel belt being torn.

[0056] Working principle: One end of the steel strip passes through the collection chamber 33 and is installed between the first clamping plate 6 and the second clamping plate 24. Then, an external winding device is used to traction and wind the steel strip. During the process of the steel strip being tractioned and moving by the external winding device, if there are excess edges and corners on both sides of the steel strip, they will slide into between the cutting and pressing wheels 8, and the cutting and pressing wheels 8 are used to roll-press the excess edges and corners on both sides of the steel strip. There are multiple cutting and pressing wheels 8, and they are symmetrically arranged. Thus, multiple cutting and pressing wheels 8 can be used to roll-press the excess edges and corners on both sides of the steel strip multiple times, making the rolled imprints deeper and thinner, thereby improving the stability and safety during the edge cutting of the steel pipe. After the excess edges and corners on both sides of the steel strip are rolled with cutting imprints, as the steel strip moves under the traction of the external winding device, the cutting knife 23 will cut the excess edges and corners on both sides of the steel strip along the rolled cutting imprints. At the same time, the grinding blocks between the cutting knives 23 are used to grind and repair the places where the excess edges and corners of the steel strip are cut, ensuring the flatness of both sides of the steel strip;

[0057] When cutting the edges of steel strips with different widths, by driving the crank 2 to rotate, the bidirectional threaded rod 12 is driven to rotate at the same time. During the rotation of the bidirectional threaded rod 12, the two T-shaped sliders 13 are thread-driven to move closer to each other inside the inner cavity of the fixed frame 5. Thus, the T-shaped sliders 13 drive the second clamping plate 24 to move synchronously, and at the same time, the second clamping plate 24 drives the first clamping plate 6 to move, so as to facilitate adjustment according to the width of the steel strip, so that the first clamping plate 6 and the second clamping plate 24 can clamp and limit the steel strip, improving the practicability of the cold-rolled steel strip edge cutting device;

[0058] When repairing the edges of the steel strip, the steel strip coil is placed outside the transmission column 41. At the same time, the bidirectional lead screw 43 is driven to rotate. Then, the bidirectional lead screw 43 thread-drives the two sliding disks 44 to move closer to each other, and the sliding disks 44 drive the push rod 45 to move synchronously. At the same time, the push rod 45 pushes the clamping rod 46 to slide out from the inner cavity of the limit chute 42. Thus, the clamping rod 46 expands and presses the steel strip coil to be fixed outside the transmission column 41. Then, the steel strip is pulled out from outside the steel strip coil, and the steel strip passes through the collection chamber 33 and contacts another transmission column 41. At the same time, the clamping rod 46 is used to drive the steel strip to be clamped and fixed with the transmission column 41. Then, the drive motor is used to drive the drive sprocket 14 to rotate, and the drive sprocket 14 drives the chain 15 to rotate. At the same time, the chain 15 drives the driven sprocket 16 to rotate. During the rotation of the driven sprocket 16, the two transmission columns 41 are driven to rotate. Thus, the transmission column 41 drives the steel strip to be wound, and at the same time, the transmission column 41 on the right side of the edge cutting device main body 1 drives the steel strip coil to discharge the steel strip. Thus, the steel strip passes between the edge cutting devices, and then the edge cutting devices are used to cut and repair the excess edges and corners of the steel strip. The excess edges and corners cut from both sides of the steel strip will directly fall into the collection chamber 33, and then the waste materials generated by the steel strip edge cutting are collected and processed by the collection frame 28.
