Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an automatic alignment baffle for a bar cooling bed. Background Technology

[0002] The bar cooling bed consists of a skirt plate, cooling bed rack, alignment roller conveyor, steel conveyor chain, traverse trolley, input and output roller conveyors, and corresponding transmission and electrical detection components. The cooling bed rack consists of two parts: a moving rack and a stationary rack. Its main purpose is to ensure uniform cooling of the finished steel on the cooling bed. However, the heads and tails of the steel bars falling from the skirt plate are not aligned when they are placed on the bed. When these unaligned steel bars are moved to the output roller conveyor by the steel conveyor chain and traverse trolley and transported to the cold shear, they cannot be effectively aligned. The uneven finished products cannot improve the yield and shearing quality of the bar stock.

[0003] The existing alignment method suffers from severe wear on the hydraulic cylinder-driven slider and frequent friction between the baffle and the tail of the steel during actual operation. This requires frequent manual switching of the baffle and the hydraulic cylinder connecting slider. Furthermore, it is only suitable for products with 3 cuts or less. It cannot achieve the tail scrap removal function when producing 12- and 14-size steel with 4 cuts or more. Therefore, an automated cooling bed tail scrap removal device suitable for 4-cut and above processes is needed. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic alignment baffle for bar cooling beds, in order to solve the problems of existing alignment methods in actual operation. Due to the severe wear of the hydraulic cylinder-driven slider and the frequent friction between the baffle and the tail of the steel, the baffle and the hydraulic cylinder connecting slider need to be frequently switched manually. Furthermore, the existing method is only suitable for products with 3 cuts or less, and cannot achieve the tail rejection function when producing 4-cut and 5-cut processes of 12- and 14-cut specifications.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: an automatic alignment baffle for a bar cooling bed, comprising a base, a bracket on the base, the bracket being "I"-shaped, a cylinder fixedly connected to the bracket, a baffle one fixedly connected to one side of the bracket, the baffle one being wedge-shaped with the bracket, a connecting plate on the side of the bracket adjacent to the baffle one, a baffle two fixedly connected to the piston rod of the cylinder, the piston rod of the cylinder driving the baffle two to move through the connecting plate, and a limiting component on the bracket for limiting the tail position of the last bar in the same batch.

[0006] The principle and beneficial effects of this utility model are as follows: Baffle 1 and Baffle 2 are used to align the bars conveyed by the roller conveyor on the cooling bed. Based on the bar cutting process of the corresponding batch, when the skirt plate discharges the last segment of the same bar after cutting, the skirt plate sends a signal to the transmission device of the cooling bed rack. When this segment of bar reaches this utility model, the transmission device of the cooling bed rack sends a signal to the cylinder. After receiving the signal, the cylinder automatically retracts its piston rod, driving Baffle 2 to move into the support. The last segment of bar is then conveyed to the limiting component via the conveyor roller conveyor, where the limiting component limits this segment. This utility model can effectively align the tail of the bar and, while aligning the remaining segments, can specially position the last segment, allowing for rapid screening of the last segment in subsequent shearing processes and cutting and removing its tail, thus achieving automated alignment and screening.

[0007] Option 2, a preferred option of the basic design, features a reinforcing plate at the connection between the bracket and the base, located on the side furthest from the first baffle. This reinforcing plate enhances the stability of the connection between the bracket and the base.

[0008] Option 3, an optimal choice from the basic option, includes a limiting assembly comprising a motor and a lead screw. The electrode is placed on a base, and the lead screw moves through the motor. One end of the lead screw is fixed to the inner ring of a bearing, and the outer ring of the bearing is fixed to a limiting plate. The motor rotates the lead screw, which in turn moves the limiting plate back and forth. The position of the limiting plate can be adjusted according to the product plan corresponding to different specifications, thereby adjusting the shearing range of the final section of the bar.

[0009] Option 4, a preferred option of Option 2, has a pulley at its bottom, which is slidably connected to the base. Using the pulley to assist the movement of the baffle 2 reduces the pressure on the cylinder piston rod and also reduces friction between the baffle 2 and the base.

[0010] Option 5, an optimal choice from the basic options, features a second pulley at the bottom of the limiting plate, which is slidably connected to the base. Using the second pulley to replicate the movement of the limiting plate reduces the pressure on the lead screw and minimizes friction between the limiting plate and the base.

[0011] Option six, an optimal choice from option three, involves electrically connecting both the cylinder and the motor to the PLC controller. By remotely controlling the extension and retraction of the cylinder piston rod and the rotation direction and frequency of the motor using the PLC controller, automated alignment of the bars can be achieved.

[0016] Example

[0017] The basic implementation examples are as follows: Figure 1 and attached Figure 2 As shown: An automatic alignment baffle for a bar cooling bed includes a base 1, a bracket 3 mounted on the base 1, the bracket 3 being I-shaped, a cylinder 4 fixedly connected to the bracket 3, a baffle 5 fixedly connected to one side of the bracket 3, the baffle 5 forming a wedge shape with the bracket 3, a connecting plate 6 provided on the side of the bracket 3 adjacent to the baffle 5, a second baffle 7 fixedly connected to the piston rod of the cylinder 4, the piston rod of the cylinder 4 driving the second baffle 7 to move through the connecting plate 6, and a limiting component provided on the bracket 3 for limiting the tail position of the last bar in the same batch, the limiting component including... The motor 8 and lead screw 9 are mounted on the base 1. The lead screw 9 moves through the motor 8. One end of the lead screw 9 is fixed to the inner ring of the bearing 10. The outer ring of the bearing 10 is fixed to the limit plate 11. The bottom of the baffle 2 7 is provided with pulley 12, which is slidably connected to the base 1. The bottom of the limit plate 11 is provided with pulley 2 13, which is slidably connected to the base 1. The connection between the bracket 3 and the base 1 is provided with a reinforcing plate 2, which is located on the side opposite to the baffle 1 5. The cylinder 4 and the motor 8 are both electrically connected to the PLC controller.

[0018] The implementation method of this embodiment is as follows:

[0019] During the 4-splitting process, the process program is set via the central controller. The skirt plate continuously feeds the splitting bars to the cooling bed. The cooling bed rack sequentially conveys the splitting bars forward. At this time, the piston rod of cylinder 4 is extended, pushing baffle 2 7 out of connecting plate 6. After the forward-conveyed bars move to this device via the conveyor rollers, the inclination angle of baffle 1 5 causes the five bar segments abutting against baffle 1 5 to be arranged at an angle. After the first four bar segments pass baffle 1 5, they abut against baffle 2 7 in sequence for tail alignment. After the first four bar sections pass through baffle 2 7, cylinder 4 drives baffle 1 5 to retract. At the same time, motor 8 rotates screw 9, causing it to move limit plate 11 forward. After limit plate 11 moves to the designated position, motor 8 stops, and the fifth bar section abuts against limit plate 11. This process causes the fifth bar section to protrude beyond the first four bar sections. After the fifth bar section passes limit plate 11, motor 8 rotates screw 9 in the opposite direction, causing it to move limit plate 11 backward. At the same time, cylinder 4 drives baffle 1 5 to extend out of connecting plate 6, and the alignment work continues to repeat.
