Description

Technical Field

[0001] The present application belongs to the technical field of metal processing equipment, and more specifically, relates to a leveling machine. Background Art

[0002] The flattening machine is a common mechanical equipment used to process metal sheets. The flattening machine can cut the rolled sheets into the required length to convert the steel coils into steel plates.

[0003] The existing leveling machine includes an upper measuring pinch roller, a lower measuring pinch roller and a cylinder. The output end of the cylinder is connected to the upper measuring pinch roller. The cylinder is used to drive the upper measuring pinch roller to move relative to the lower measuring pinch roller. Since the steel plate transmitted by the leveling machine may be abnormally warped, the steel plate is prone to direct collision with the cylinder, thereby causing damage to the cylinder and triggering a series of safety accidents. Therefore, the leveling machine has poor stability and insufficient safety. Utility Model Content

[0004] One of the purposes of the embodiments of the present application is to provide a leveling machine to solve the technical problem in the prior art that when the steel plate transmitted by the leveling machine is warped, the steel plate is prone to direct collision with the cylinder, resulting in poor stability and insufficient safety of the leveling machine.

[0005] To solve the above technical problems, in the first aspect, an embodiment of the present application provides a leveling machine for transmitting steel plates, the leveling machine comprising a working platform and a pinch roller arch, the working platform is connected to the pinch roller arch, the side of the working platform facing the pinch roller arch is for the transmission steel plate to be placed and is equipped with a lower ranging pinch roller; the pinch roller arch is equipped with a support frame and a cylinder, one side of the support frame is hinged to the pinch roller arch, and the other side is rotatably connected to an upper ranging pinch roller, the output end of the cylinder is connected to the support frame, and is used to drive the support frame to swing relative to the pinch roller arch; the pinch roller arch is also connected to a guardrail, and the guardrail is arranged around the outer periphery of the support frame; a distance sensor is suspended on the side of the guardrail away from the pinch roller arch, the distance sensor is electrically connected to a proximity switch, and the distance sensor is used to sense the warping of the steel plate so that the proximity switch controls the start and stop of the leveling machine.

[0006] The beneficial effect of the leveling machine provided by the present application is that: by setting up an operating platform and a pinch roller arch to cooperate with each other, the operating platform is provided with a lower ranging pinch roller, and the pinch roller arch is installed with an upper ranging pinch roller through a support frame, and a transmission gap can be formed between the upper ranging pinch roller and the lower ranging pinch roller for the steel plate to pass through, and the cylinder can drive the support frame to swing relative to the pinch roller arch, so that the upper ranging pinch roller and the lower ranging pinch roller are respectively pressed against the two side surfaces of the steel plate, thereby ensuring that the steel plate is transported more smoothly. Compared with the leveling machine in the prior art, the pinch roller arch of the present application is also connected to a guardrail, and a distance sensor is suspended and installed on the guardrail. The distance sensor can sense the warping of the steel plate surface and send a signal to the proximity switch, so that the proximity switch stops the operation of the leveling machine in time after receiving the signal, thereby preventing the steel plate from continuing to move; in the special case where the distance sensor or the proximity switch fails and causes the warped steel plate to continue to move, the guardrail can collide with the steel plate to prevent the steel plate from colliding with the cylinder, thereby ensuring the safety of the cylinder, and the leveling machine has better stability and higher safety.

[0007] In a feasible technical solution, the guardrail includes a crossbeam and two longitudinal beams. The crossbeam is arranged opposite to the pinch roller arch. The two longitudinal beams are respectively connected to the opposite ends of the crossbeam, and one end of each longitudinal beam away from the crossbeam is respectively connected to the pinch roller arch.

[0008] By adopting such a design, the guardrail has a simple structure and high production efficiency.

[0009] In a feasible technical solution, the cross beam and the two longitudinal beams are further away from the lower distance measuring pinch roller relative to the upper distance measuring pinch roller.

[0010] By adopting such a design, it can be ensured that when the steel plate is normally transported, the cross beam and the longitudinal beam will not collide with the steel plate.

[0011] In a feasible technical solution, the orthographic projection of the crossbeam on the working platform is farther away from the pinch roller arch relative to the lower ranging pinch roller.

[0012] By adopting such a design, when the steel plate is warped, it can be prevented from being transported around the longitudinal beam through the gap between the cross beam and the working platform, so as to ensure that the longitudinal beam can collide with the steel plate, thereby realizing the protective function of the guardrail.

[0013] In a feasible technical solution, the guardrail also includes two diagonal braces, which correspond one to one with the two longitudinal beams, and each of the diagonal braces is connected to the pinch roller arch at one end and to the crossbeam or the corresponding longitudinal beam at the other end.

[0014] By adopting such a design, the connection stability between the guardrail as a whole and the pinch roller arch can be enhanced.

[0015] In a feasible technical solution, the guardrail further includes a cantilever, and two ends of the cantilever are respectively connected to the crossbeam and the distance sensor.

[0016] By adopting such a design, the distance sensor can be conveniently installed on the guardrail, and the assembly efficiency is higher.

[0017] In a feasible technical solution, the number of the cantilevers is the same as that of the distance sensors and both are multiple, and the multiple cantilevers correspond to the multiple distance sensors one by one.

[0018] By adopting such a design, the accuracy of the flattening machine in sensing the warping degree of the steel plate can be improved to meet higher precision production requirements.

[0019] In a feasible technical solution, the cylinder is hinged to the pinch roller arch, and the connection between the cylinder and the pinch roller arch is farther away from the working platform than the connection between the support frame and the pinch roller arch.

[0020] By adopting such a design, the cylinder can be further away from the steel plate relative to the entire support frame, so as to further avoid collision between the steel plate and the cylinder.

[0021] In a feasible technical solution, the support frame includes a rotating shaft and two connecting rods, each of the connecting rods is hinged to the pinch roller arch, the rotating shaft is closer to the pinch roller arch than the upper ranging pinch roller, the output end of the cylinder is rotatably connected to the middle part of the rotating shaft, and both ends of the rotating shaft and both ends of the upper ranging pinch roller are rotatably connected to the two connecting rods.

[0022] By adopting such a design, the support frame has a simple structure and is more convenient to produce and process.

[0023] In a feasible technical solution, an encoder is installed at the end of the upper distance measuring pinch roller, and the encoder is used to measure the conveying distance of the steel plate.

[0024] By adopting such a design, the encoder can calculate the length of the steel plate using the number of revolutions and the circumference of the upper ranging pinch roller, and feed the data back to other equipment to make subsequent processing of the steel plate more accurate.

[0045] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0046] Please also read Figures 1 to 3 The embodiment of the present application provides a leveling machine, which includes a working platform 10 and a pinch roller arch 20. The working platform 10 is connected to the pinch roller arch 20. The working platform 10 faces the pinch roller arch 20 on one side for placing a transmission steel plate 100 and is equipped with a lower distance measuring pinch roller 30. The pinch roller arch 20 is equipped with a support frame 40 and a cylinder 50. One side of the support frame 40 is hinged to the pinch roller arch 20, and the other side is rotatably connected to an upper distance measuring pinch roller 60. The output end of the cylinder 50 is connected to the support frame 40 to drive the support frame 40 to swing relative to the pinch roller arch 20. The pinch roller arch 20 is also connected to a guardrail 70. The guardrail 70 is arranged around the outer periphery of the support frame 40. A distance sensor 80 is suspended on the side of the guardrail 70 away from the pinch roller arch 20. The distance sensor 80 is electrically connected to the proximity switch. The distance sensor 80 is used to sense the warping of the steel plate 100 so that the proximity switch controls the start and stop of the leveling machine.

[0047] By setting the working platform 10 and the pinch roller arch 20 to cooperate with each other, the working platform 10 is provided with a lower distance measuring pinch roller 30, and the pinch roller arch 20 is installed with an upper distance measuring pinch roller 60 through a support frame 40. A transmission gap can be formed between the upper distance measuring pinch roller 60 and the lower distance measuring pinch roller 30 for the steel plate 100 to pass through. The cylinder 50 can drive the support frame 40 to swing relative to the pinch roller arch 20, so that the upper distance measuring pinch roller 60 and the lower distance measuring pinch roller 30 are respectively pressed against the two side surfaces of the steel plate 100, ensuring that the transportation of the steel plate 100 is more stable; the pinch roller arch 20 is also connected with The guardrail 70 is equipped with a distance sensor 80 which can sense the warping of the surface of the steel plate 100 and send a signal to the proximity switch so that the proximity switch can stop the operation of the leveling machine in time after receiving the signal, thereby preventing the steel plate 100 from continuing to move. In the special case where the distance sensor 80 or the proximity switch fails, causing the warped steel plate 100 to continue to move, the guardrail 70 can collide with the steel plate 100 to prevent the steel plate 100 from colliding with the cylinder 50, thereby ensuring the safety of the cylinder 50 and improving the stability and safety of the leveling machine.

[0048] In application, the leveling machine is provided with a transmission device for transmitting the steel plate 100. The transmission device, the proximity switch and the distance sensor 80 are electrically connected. The steel plate 100 moves from the side of the working platform 10 close to the pinch roller arch 20 toward the side of the working platform 10 close to the distance sensor 80. The output end of the cylinder 50 performs telescopic movement to adjust the relative position of the upper ranging pinch roller 60 and the lower ranging pinch roller 30, so that the upper ranging pinch roller 60 and the lower ranging pinch roller 30 are pressed against the opposite sides of the steel plate 100.

[0049] In application, the distance sensor 80 can emit laser toward the steel plate 100 for distance measurement. The proximity switch can be an electromagnetic relay or a single-chip microcomputer. The proximity switch has a built-in program to set the warping limit value of the steel plate 100. The value detected by the distance sensor 80 is compared with the warping limit value to control the start and stop of the leveling machine.

[0050] Specifically, when the warping value of the steel plate 100 detected by the distance sensor 80 is less than the warping limit value, the leveling machine keeps running and the transmission device can continue to transport the steel plate 100. When the warping value of the steel plate 100 detected by the distance sensor 80 is not less than the warping limit value, the proximity switch stops the operation of the leveling machine and the transmission device stops transporting the steel plate 100.

[0052] In application, the pinch roller arch 20 and the guardrail 70 are both made of metal, and the opposite ends of the longitudinal beam 72 are respectively welded or bolted to the cross beam 71 and the pinch roller arch 20. It can be understood that the guardrail 70 can also be made of plastic material, and the cross beam 71 and the two longitudinal beams 72 are integrally injection molded, and the end of the longitudinal beam 72 is bolted to the pinch roller arch 20. The guardrail 70 has a simple structure and high production efficiency.

[0061] In one embodiment, please refer to Figures 1 to 3 The guardrail 70 further includes a cantilever 74 , and two ends of the cantilever 74 are respectively connected to the crossbeam 71 and the distance sensor 80 .

[0062] In application, by adopting such a design, the distance sensor 80 can be conveniently installed on the guardrail 70, and the assembly efficiency is higher.

[0063] In another embodiment, see Figure 4 The number of cantilevers 74 and the number of distance sensors 80 are the same and both are multiple, and the multiple cantilevers 74 correspond to the multiple distance sensors 80 one by one.

[0064] In application, by adopting such a design, the accuracy of the flattening machine in sensing the warping degree of the steel plate 100 can be improved to meet higher precision production requirements.

[0065] In one embodiment, please refer to Figures 1 to 3 The cylinder 50 is hinged to the pinch roller arch 20 , and the connection between the cylinder 50 and the pinch roller arch 20 is farther away from the working platform 10 than the connection between the support frame 40 and the pinch roller arch 20 .

[0066] In application, by adopting such a design, the cylinder 50 can be further away from the steel plate 100 relative to the entire support frame 40 to further avoid collision between the steel plate 100 and the cylinder 50 .

[0067] In one embodiment, please refer to Figures 1 to 3 The support frame 40 includes a rotating shaft 41 and two connecting rods 42. Each connecting rod 42 is hinged to the pinch roller arch 20. The rotating shaft 41 is closer to the pinch roller arch 20 than the upper measuring pinch roller 60. The output end of the cylinder 50 is rotatably connected to the middle of the rotating shaft 41. Both ends of the rotating shaft 41 and both ends of the upper measuring pinch roller 60 are rotatably connected to the two connecting rods 42.
