Description

Technical Field

[0001] The invention relates to the technical field of iron scale removing devices, in particular to a rolling-cutting double-sided shearing iron scale removing device. Background Art

[0002] Because the warm straightening machine in the wide and thick plate plant is arranged behind the cooling bed, the straightening temperature of thin-gauge steel plates after the cooling bed is low, and the brittle iron oxide scale at low temperature is severely broken after straightening. When the steel plate is sheared on both sides, the vibration caused by the blade shearing causes a large amount of broken iron oxide scale to fall into the scissor machine platform, adhere to the surface of the pinch roller and the surface of the presser foot, causing the surface of the pinch roller and the presser foot to bulge locally, directly causing corresponding indentations on the surface of the steel plate, and when the subsequent steel plate passes through the scissor machine platform, more iron oxide scale will also adhere to the lower surface, and will be pressed into the surface of the steel plate through the pinch roller and the presser foot to cause defects.

[0003] The traditional device only has a rubber pad scraper for the pinch roller, which can only clean the iron oxide scale on the surface of the pinch roller. The pinch roller will cause the iron oxide scale to adhere to the surface of the pinch roller due to the large amount of iron oxide scale on the steel plate, thereby causing indentations on the steel plate when the pinch roller conveys the steel plate. In addition, the traditional shearing device will continuously blow air through the air pipe during use, which may cause the iron oxide scale to be blown into the eyes of the staff when they come forward to check the machine.

[0004] In view of this, research and improvement are carried out on the existing problems, and a rolling-cut double-sided shear oxide scale removal device is provided. The device has a reasonable structural design, high stability, and takes all aspects of application into consideration. The purpose is to solve the problem and improve the practical value through this technology. Summary of the invention

[0005] The present invention blows air to the upper and lower ends of the steel plate when the steel plate enters, thereby blowing off the oxidized iron scale on the surface of the steel plate, preventing the oxidized iron scale from adhering to the first conveyor roller and the surface of the presser foot during the conveying process of the first conveyor roller, causing the first conveyor roller and the surface of the presser foot to be locally bulged, thereby causing indentations on the surface of the steel plate. At the same time, the conveying main pipe is controlled by a valve, so that the equipment starts air intake and blowing when it is running, and the air intake will gradually stop when the valve is closed, so that it is convenient for staff to come forward to check, thereby realizing a rolling-cutting type double-sided shearing oxidized iron scale removing device.

[0016] 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.

[0017] Reference Figure 1-5 An embodiment of the present invention is a rolling-cut double-sided shearing scale removing device, comprising a base 1, a protective outer cover 2 fixedly connected to the upper end of the base 1, a motor 3 for driving fixedly connected to one side of the outer cover 2, a first conveying roller 4 is arranged on the inner side of the outer cover 2, connecting shafts 5 are fixedly connected to both ends of the first conveying roller 4, a first cleaning purge pipe 6 is fixedly connected to one side of the first conveying roller 4 close to the outer end, a nozzle 7 is fixedly connected to one side of the first purge pipe 6 close to the inner side, a connecting pipe 8 for transmission is fixedly connected to the upper end of the first purge pipe 6, two groups of second purge pipes 9 are fixedly connected to both sides of the first conveying roller 4, a pulley A10 is fixedly connected to the outer side of the connecting shaft 5, a pulley B11 is arranged on one side of the pulley A10, a belt 12 for transmission is arranged on the inner side of the pulley A10, a cutting blade 13 is fixedly connected to one side of the pulley B11 close to the inner side, and a wear-resistant platform 14 is fixedly connected to the center of the inner side of the outer cover 2.

[0018] In an optional embodiment: the outer cover 2 is installed and fixed by the base 1, and the lower end of the outer cover 2 is hollow, which is convenient for the iron sheet produced by cutting to fall to the lower end to prevent it from accumulating inside and making it difficult to clean, and also facilitates subsequent cleaning. The motor 3 is fixedly connected with several groups on one side of the outer cover 2, and the driving end of each group of motors 3 is connected to the connecting shaft 5 at one end of the first conveying roller 4. The first conveying roller 4 is connected to the inner wall of the outer cover 2 through the connecting shafts 5 at both ends. Two groups of first purge pipes 6 are fixedly connected at one end of the outer cover 2, and the two groups of first purge pipes 6 are provided with several groups of nozzles 7, and each group of nozzles 7 is inclined toward the center. When the steel plate enters, it blows air to the upper and lower ends of the steel plate to blow away the oxidized iron sheet on the surface of the steel plate, preventing it from being attached to the first conveying roller 4 and the surface of the presser foot during the conveying process of the first conveying roller 4, resulting in local bulges of the first conveying roller 4 and the surface of the presser foot, thereby causing indentations on the surface of the steel plate.

[0019] In an optional embodiment: the first purge pipe 6 is connected to the two groups of second purge pipes 9 by a connecting pipe 8, and a plurality of groups of nozzles 7 are connected to the outer side of the second purge pipes 9. The nozzles 7 on the outer sides of the two groups of second purge pipes 9 are inclined toward the lower end and are located between the first conveyor rollers 4. When the steel plate is sheared on both sides, the vibration generated by the shearing of the cutting blade 13 causes a large amount of broken iron oxide to fall onto the shearing machine platform. At this time, the second purge pipe 9 will blow the generated iron oxide to the lower end, and at the same time blow air to the outer surface of the first conveyor roller 4, thereby cleaning the outer surface of the first conveyor roller 4.

[0020] In an optional embodiment: the cutting blade 13 is arranged at the gap at both ends of the first conveying roller 4, and the cutting blade 13 is arranged at both ends of the first conveying roller 4, and the two groups of cutting blades 13 are connected to each other, the pulley A10 is connected to the pulley B11 by the belt 12, and the wear-resistant platform 14 is fixed by connecting the lower end to the inner side of the outer cover 2, and the upper surface of the wear-resistant platform 14 is flush with the center of the first conveying roller 4, and the two groups of cutting blades 13 are movably connected to the inner wall of the outer cover 2. When the motor 3 drives the connecting shaft 5 to drive the first conveying roller 4 to rotate, the connecting shaft 5 will drive the pulley A10 to rotate synchronously, and the pulley A10 will drive the pulley B11 to rotate synchronously through the belt 12. Because the pulley B11 is connected to the cutting blade 13, the cutting blade 13 will be driven to rotate synchronously when the pulley B11 rotates, and the outer diameter of the pulley A10 is larger than the pulley B11, so the rotation frequency of the pulley B11 is greater than that of the pulley A10, and the two groups of cutting blades 13 are connected to each other, so that cutting is performed during the conveying process.

[0021] In an optional embodiment: a third purge pipe 15 is provided on one side of the wear-resistant platform 14, and the third purge pipe 15 passes through the outer cover 2 and is connected to the connecting pipe 8, and a conveying main pipe 16 is provided on the upper end of the third purge pipe 15, one end of the conveying main pipe 16 is connected to the connecting pipe 8, and the other end is connected to the air intake device. The third purge pipe 15 blows away the iron sheet generated by the steel plate when passing through the wear-resistant platform 14, thereby preventing excessive iron sheet from being accumulated on the surface of the wear-resistant platform 14, which may cause indentation to the steel plate during rear-end transportation.

[0022] In an optional embodiment: one side of the third purge pipe 15 is connected to the fourth purge pipe 17 through the connecting pipe 8, and a plurality of groups of nozzles 7 are fixedly connected to the outer side of the fourth purge pipe 17, and each group of nozzles 7 is slightly upward, and a second conveying roller 18 is arranged on the upper end of the fourth purge pipe 17, and the second conveying roller 18 is rotated by the drive of the motor 3, and each group of nozzles 7 on the outer side of the fourth purge pipe 17 is aligned with each group of second conveying rollers 18, so that when conveying the steel plate after cutting, the surface of the second conveying roller 18 is cleaned to prevent the long-term accumulation of iron oxide scale from causing defects on the surface of the steel plate.

[0023] In an optional embodiment: a group of the first conveying rollers 4 near the inner upper end is connected to a connecting rod 19 through a connecting shaft 5, and the connecting rod 19 extends through the outer cover 2 to the outer end and is connected to a rack 20, a gear 21 is provided on one side of the conveying main pipe 16, the gear 21 is located at the upper end of the rack 20, and the rack 20 is meshed with the gear 21, and one end of the gear 21 near the conveying main pipe 16 is fixedly connected to a spring rod 22, and the gear 21 is connected to the conveying main pipe 16 through the spring rod 22, and the spring rod 22 penetrates the conveying main pipe 16 and is connected to the internal valve of the conveying main pipe 16. When the equipment is started, when the motor 3 drives the first conveying rollers 4 to drive the motor 3 to rotate, a group of the first conveying rollers 4 at the rear end will drive the rack 20 to rotate synchronously through the connecting rod 19, and when the rack 20 rotates, it will continuously pass through the internal The tooth holes drive the gear 21 to rotate. Because the gear 21 is connected to the internal valve of the conveying main pipe 16 through the spring rod 22, when the rack 20 drives the gear 21 to rotate, the internal valve of the conveying main pipe 16 will be opened to intake air. Because the spring rod 22 has a certain tension, when the gear 21 is rotated, the spring rod 22 will drive the gear 21 to gradually rebound and reset. At the same time, the internal valve of the conveying main pipe 16 will be closed. Therefore, during the rotation of the rack 20, the internal valve of the conveying main pipe 16 will be continuously driven to open. When the equipment is closed, the rotation of the rack 20 will be stopped, so that the spring rod 22 will gradually close the valve inside the conveying main pipe 16, and the air intake into the connecting pipe 8 will be stopped, so as to prevent the staff from causing iron sheet splashing and causing harm to the body when they go forward to check after cutting a group of steel plates.

[0024] Working principle and process: The staff turns on the equipment, drives the first conveyor roller 4 to rotate through the motor 3 to convey the steel plate. While conveying, the two sets of cutting blades 13 will be driven by the transmission of the pulley A10 to rotate synchronously to cut the steel plate, and before the steel plate enters the equipment, the two sets of first purge pipes 6 will blow air to the upper and lower ends of the steel plate. The second purge pipe 9 will blow air to the surface and cutting position of the first conveyor roller 4 during cutting and conveying, so as to prevent the iron sheet from adhering to the surface of the first conveyor roller 4. At the same time, during the rotation of the first conveyor roller 4, the connecting rod 19 will drive the rack 20 to rotate to control the air intake of the conveying main pipe 16, so as to blow air while cutting.
