Description

Technical Field

[0001] This utility model relates to the field of steel coil shearing technology, and in particular to a high-efficiency tooling for continuous shearing and forming of steel coils. Background Technology

[0002] Steel coils, also known as rolled steel, are steel products that have been hot-rolled or cold-pressed into coils. To facilitate storage and transportation, as well as various processing, the main types of coils are hot-rolled coils and cold-rolled coils. Hot-rolled coils are processed products before the recrystallization of steel billets, while cold-rolled coils are processed after hot-rolled coils. In the use of steel coils, it is often necessary to cut them.

[0003] During steel coil cutting, the process takes time, causing the steel coil conveying device to pause briefly. However, frequent start-stop cycles reduce production efficiency and increase equipment wear and maintenance costs. Currently, the common method to avoid conveyor shutdowns is to install storage pits to store and buffer the steel coils, thus adjusting the production rhythm.

[0004] However, the introduction of the storage pit increases the complexity and risk of equipment failure, and occupies a significant amount of space. In addition to the original feeding and cutting equipment, additional equipment is needed to move the steel coils in and out of the storage pit, such as overhead cranes and hoists, as well as potentially supporting guiding and positioning devices. The coordinated operation of these new devices requires a more complex control system, increasing the difficulty of equipment installation, commissioning, and subsequent maintenance. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency tooling for continuous shearing and forming of steel coils, aiming to solve the problems of increased equipment complexity and failure risk, as well as the large space occupation caused by the storage pit during current steel coil shearing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency tooling for continuous shearing and forming of steel coils, including a lead screw and a shearing table. The outer wall of the lead screw is provided with a ball bearing mechanism, and a laser shearing device is provided on the lower side of the ball bearing mechanism. Both ends of the lead screw are provided with driving mechanisms. The front driving mechanism is equipped with a second motor, the output end of which is located at the front end of the lead screw. The driving mechanism is equipped with a first motor, the output end of which is provided with a gear. The teeth of the gear are meshed with a rack. A crossbeam is provided on the lower side of the rack. Supports are fixedly connected to the lower sides of both ends of the crossbeam. The lower sides of the four supports are fixedly connected to the upper side of the shearing table. A steel coil is placed on the shearing table below the two crossbeams.

[0007] Preferably, a slide bar is provided on the upper side of the laser shearing device, and the upper side of the slide bar is provided on the lower side of the ball bearing mechanism. A vertical frame is fixedly connected to the side wall between the two drive mechanisms. The middle part of the vertical frame is a hollow structure, and the side wall of the slide bar is slidably connected to the middle part of the vertical frame.

[0008] Preferably, a bearing is fixedly connected inside the rear drive mechanism, the lead screw passes through the drive mechanism, and the rear end of the lead screw is disposed on the inner ring of the bearing.

[0009] Preferably, the crossbar and rack pass through the left and right side walls of the drive mechanism.

[0010] Preferably, connecting plates are fixedly connected to both the left and right sides inside the drive mechanism, and connecting rods are fixedly connected to the lower side of the connecting plates. Rollers are provided at both ends of the connecting rods, and the rollers are slidably connected to the upper side of the crossbeam.

[0011] Preferably, the upper side of the crossbeam is provided with two sliding grooves, which are respectively located on the front and rear sides of the rack, and a predetermined distance is maintained between the sliding grooves and the rack. The sliding grooves are slidably connected to the rollers.

[0012] Preferably, the bottom of the connecting rod is higher than the top of the rack.

[0013] Preferably, a cylinder is provided on the shearing table, and a baffle is provided at the output end of the cylinder. The side of the baffle away from the cylinder is in contact with the steel coil, and a predetermined distance is maintained between the baffle and the steel coil. There are four cylinders, which are evenly distributed at the four corners of the shearing table on the same plane. The baffle and the crossbar maintain a predetermined distance.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the shearing table supports the bracket. The output of motor one drives the gear to rotate. Through the meshing connection of the gear and rack, motor one moves on the horizontal frame, thereby driving the drive mechanism to move, which in turn drives the lead screw and laser shearing device to move. When the moving speed of the vertical frame is the same as the moving speed of the steel coil, the output of motor two starts to drive the lead screw to rotate, thereby realizing the laser shearing device to shear the steel coil. This solves the problem that the storage pit increases the complexity of the equipment and the risk of failure, and occupies a lot of space when shearing steel coils.

[0016] 2. In this utility model, the sliding connection between the groove and the roller provides support for the connecting rod, which in turn supports the connecting plate, thereby supporting the drive mechanism; thus improving the stability of the device. Attached Figure Description

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a high-efficiency tooling for continuous shearing and forming of steel coils, including a lead screw 3 and a shearing table 7. A ball bearing mechanism 2 is provided on the outer wall of the lead screw 3, and a laser shearing device 6 is provided on the lower side of the ball bearing mechanism 2. Both the front and rear ends of the lead screw 3 are provided with a drive mechanism 11. A second motor 20 is provided inside the front drive mechanism 11, and the output end of the second motor 20 is located at the front end of the lead screw 3. A first motor 18 is provided inside the drive mechanism 11, and a gear 19 is provided at the output end of the first motor 18. The tooth end of the gear 19 is meshed with a rack 12. A crossbeam 10 is provided on the lower side of the rack 12. A bracket 1 is fixedly connected to the lower side of both ends of the crossbeam 10. The lower sides of the four brackets 1 are fixedly connected to the upper side of the shearing table 7. A steel coil 13 is provided on the shearing table 7 below the two crossbeams 10.

[0025] In this embodiment, Figure 1 The directions are front, back, left, and right. The laser shearing device 6 uses a laser to shear the steel coil 13, which is existing technology. Specifically, when using this device, the vertical frame 4 is located at the far left of the horizontal frame 10, and the laser shearing device 6 is located at the far front of the vertical frame 4. After the steel coil 13 moves a certain distance at a constant speed on the shearing table 7, the output end of the motor 18 drives the gear 19 to rotate. Through the meshing connection between the gear 19 and the rack 12, the motor 18 moves on the horizontal frame 10, driving the drive mechanism 11 to move, which in turn drives the lead screw 3 and the laser shearing device 6 to move from left to right. When the moving speed of the vertical frame 4 and the moving speed of the steel coil 13 are the same, the laser shearing device 6 and the steel coil 13 are relatively stationary. The output end of the motor 20 starts to drive, driving the lead screw 3 to rotate, which in turn drives the ball bearing mechanism 2 to move, thereby driving the laser shearing device 6 to start moving from front to back to shear the steel coil 13.

[0026] After the steel coil 13 is sheared, the laser shearing device 6 stops operating. The output of motor 18 drives the gear 19 to rotate, causing motor 18 and drive mechanism 11 to move from right to left on the crossbeam 10 and move to the leftmost side of the crossbeam 10, waiting for the next shearing operation. When the next shearing operation is performed, motor 18 repeats the above actions, and motor 20 rotates in the opposite direction, causing the laser shearing device 6 to start the shearing operation from back to front. This solves the problem that the storage pit increases the complexity of the equipment and the risk of failure, and occupies a lot of space when shearing the steel coil 13.

[0027] Reference Figure 1 A slide bar 5 is provided on the upper side of the laser shearing device 6. The upper side of the slide bar 5 is located on the lower side of the ball bearing mechanism 2. A vertical frame 4 is fixedly connected to the side wall between the two drive mechanisms 11. The middle part of the vertical frame 4 is hollow. The side wall of the slide bar 5 is slidably connected to the middle part of the vertical frame 4.

[0028] Specifically, when the lead screw 3 starts to rotate, the ball mechanism 2 moves on the lead screw 3 through the sliding connection between the lead screw 3 and the ball mechanism 2. When the lead screw 3 starts or stops, the ball mechanism 2 will wobble slightly due to inertia and needs to pause for a certain period of time before shearing can be performed. Through the sliding connection between the slide rod 5 and the middle of the vertical frame 4, the vertical frame 4 and the slide rod 5 can counteract the inertial effect generated when the lead screw 3 starts or stops, thereby improving the working efficiency of the device.

[0029] Reference Figure 2 The rear drive mechanism 11 is internally fixedly connected to a bearing 14, and the lead screw 3 passes through the drive mechanism 11. The rear end of the lead screw 3 is set on the inner ring of the bearing 14.

[0030] Specifically, when the drive mechanism 11 moves, it drives the bearing 14 to move. Through the rotational connection between the lead screw 3 and the bearing 14, the bearing 14 drives the lead screw 3 to move in the same direction, thus achieving the rotational effect of the lead screw 3.

[0031] Reference Figure 1 The crossbeam 10 and the rack 12 pass through the left and right side walls of the drive mechanism 11.

[0032] Specifically, this arrangement ensures that the drive mechanism 11 does not interfere with the crossbeam 10 and rack 12 when it moves.

[0033] Reference Figure 3 and Figure 4 The drive mechanism 11 has connecting plates 15 fixedly connected to both the left and right sides inside. A connecting rod 21 is fixedly connected to the lower side of the connecting plate 15. Rollers 17 are provided at both ends of the connecting rod 21. The rollers 17 are slidably connected to the upper side of the cross frame 10.

[0034] Specifically, when the drive mechanism 11 moves on the crossbeam 10, it drives the connecting plate 15 to move, which in turn drives the connecting rod 21 to move. Through the sliding connection between the roller 17 and the crossbeam 10, the moving efficiency of the drive mechanism 11 is improved. At the same time, it also provides support for the drive mechanism 11, thereby reducing the supporting effect of the motor 18 on the drive mechanism 11 and improving the operating efficiency of the device.

[0035] Reference Figure 3 and Figure 4 The upper side of the cross frame 10 is provided with two sliding grooves 16. The two sliding grooves 16 are respectively located on the front and rear sides of the rack 12, and the sliding grooves 16 and the rack 12 maintain a predetermined distance. The sliding grooves 16 and the rollers 17 are slidably connected.

[0036] Specifically, the sliding connection between the slide groove 16 and the roller 17 reduces the probability of the drive mechanism 11 shifting back and forth during its movement on the crossbeam 10, thereby improving the stability of the lead screw 3 rotation and thus improving the accuracy of the laser shearing device 6.

[0037] Reference Figure 3 and Figure 4 The bottom of the connecting rod 21 is higher than the top of the rack 12.

[0038] Specifically, this arrangement ensures that the connecting rod 21 does not interfere with the rack 12 when it moves on the crossbeam 10, which helps to improve the operational stability of the device.

[0039] Reference Figure 1A cylinder 9 is provided on the shearing table 7. A baffle 8 is provided at the output end of the cylinder 9. The side of the baffle 8 away from the cylinder 9 is in contact with the steel coil 13, and a predetermined distance is maintained between the baffle 8 and the steel coil 13. There are four cylinders 9, which are evenly distributed at the four corners of the shearing table 7 on the same plane. The baffle 8 and the crossbar 10 maintain a predetermined distance.

[0040] Specifically, when the steel coil 13 moves onto the shearing table 7, the extension and retraction of the output end of the cylinder 9 causes the baffle 8 to come into contact with the steel coil 13 and then retract to maintain a certain distance. This ensures that the steel coil 13 does not shift during its movement and also avoids friction between the baffle 8 and the steel coil 13. The position setting of the baffle 8 ensures that the laser shearing device 6 will not interfere with the baffle 8 during operation, thereby improving the stability and accuracy of the device.

[0041] Working principle: When the steel coil 13 moves onto the shearing table 7, the extension and retraction of the output end of the cylinder 9 causes the baffle 8 and the steel coil 13 to fit together and then move back to maintain a certain distance; the vertical frame 4 is located on the far left of the horizontal frame 10, and the laser shearing device 6 is located at the far front of the vertical frame 4.

[0042] After the steel coil 13 moves a certain distance at a constant speed on the shearing table 7, it is supported by the sliding connection of the slide groove 16 and the roller 17, which in turn supports the connecting rod 21, the connecting plate 15, and the drive mechanism 11. When the output of the motor 18 drives the gear 19 to rotate, the gear 19 and the rack 12 mesh together, causing the motor 18 to move on the crossbeam 10, thereby moving the drive mechanism 11. The lead screw 3 and the vertical frame 4 are connected to the drive mechanism 11, thus moving the lead screw 3 and the vertical frame 4. This allows the laser shearing device 6 to move from left to right.

[0043] When the vertical frame 4 moves at the same speed as the steel coil 13 after being driven by motor 18, the lead screw 3 is driven to rotate by the output end of motor 20. The lead screw 3 rotates and is connected to the middle of the vertical frame 4 by sliding rod 5, thereby causing the laser shearing device 6 to move from front to back to shear the steel coil 13.

[0044] After the steel coil 13 is sheared, the laser shearing device 6 stops shearing, and the output of motor 18 reverses, driving gear 19 to rotate. This causes motor 18 and drive mechanism 11 to move from right to left on the crossbeam 10, and move to the leftmost side of the crossbeam 10, waiting for the next shearing operation. When the next shearing operation is performed, motor 18 repeats the above actions, and motor 20 rotates in the opposite direction, causing the laser shearing device 6 to start the shearing operation from back to front. This solves the problem that the storage pit increases the complexity of the equipment and the risk of failure, and occupies a lot of space when shearing the steel coil 13.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
