Description

Technical Field

[0001] This utility model relates to the field of bar rolling production technology, and in particular to bar production line grouping, specifically a bar grouping and alignment control device. Background Technology

[0002] In a bar production line, hot-rolled bars are conveyed to the cooling bed via skirts. In existing technology, bars are typically aligned at the tail end on the skirts, resulting in uneven heads when the bars enter the cooling bed.

[0003] To facilitate subsequent length-cutting, the bars must be impacted at high speed against a lifting baffle positioned in front of the sawing zone, using mechanical impact force to force the bar heads to align. This process has significant drawbacks: First, the violent impact easily causes the bars to bend and deform, severely affecting product quality; some bars may need to be straightened by a straightening machine, or even become defective products. Second, the impact alignment process prolongs the production cycle and reduces production efficiency. Third, the lifting baffle and its transmission mechanism are prone to damage under frequent impacts, increasing equipment maintenance costs. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a bar stock alignment control device that aligns the bar stock heads during the conveying process, eliminating the need for an impact alignment step.

[0005] This utility model is achieved through the following technical solution: a bar stock grouping and alignment control device is provided, including a mounting bracket fixed on a base platform in the skirt area, and a rotating shaft rotatably mounted on the mounting bracket. The axis of the rotating shaft is perpendicular to the direction of bar stock movement. A sensing plate and a trigger plate extending to the front of the bar stock head are fixed on the rotating shaft. The device also includes a proximity switch adapted to the sensing plate, and the proximity switch is electrically connected to an actuator that drives the skirt board to flip the steel.

[0006] This solution involves setting a trigger plate extending to the front of the bar head. During the forward conveying of the bar, when the bar head collides with the trigger plate, the trigger plate rotates, thereby driving the induction plate to rotate via the rotating shaft. The rotation of the induction plate causes a change in the state of the proximity switch, which drives the actuator of the skirt plate flipping steel to operate, thus driving the skirt plate to perform the flipping steel action. Since the heads of each bar collide with the trigger plate at the same position, the heads of each bar are aligned.

[0007] As an optimization, the trigger plate is tilted, and the vertical projection of the lower end of the trigger plate is located in front of the vertical projection of its upper end. This optimization scheme avoids the rod head colliding directly with the trigger plate by setting the trigger plate in a tilted state, thus reducing damage to the rod head.

[0008] As an optimization, the vertical projection of the trigger plate is located in front of the vertical plane containing the axis of rotation, while the vertical projection of the sensing plate is located behind the vertical plane containing the axis of rotation. The torque generated by the trigger plate on the axis of rotation is greater than the torque generated by the sensing plate on the axis of rotation. A limiting plate is fixed on the mounting bracket, and a limiting rod extending to the rotation trajectory of the sensing plate is fixed on the limiting plate. When the rod is not in contact with the trigger plate, the limiting rod restricts the rotation of the sensing plate. This optimized design simplifies the structure by placing the trigger plate in an inclined state. It utilizes the gravity of the trigger plate and the limiting effect of the limiting rod to keep it in an inclined state before contacting the rod. When the head of the rod touches the trigger plate, the sensing plate can rotate accordingly.

[0009] As an optimization, the sensing plate has an arc-shaped elongated hole for the limit rod to pass through. The center of the arc-shaped elongated hole is located on the axis of the rotating shaft. The limit rod is threadedly connected to fastening nuts located on both sides of the sensing plate. This optimized design allows the tilt angle of the trigger plate to be adjusted by changing the position of the limit rod in the arc-shaped elongated hole after the fastening nuts are loosened, thereby meeting the requirements for using bars of different diameters.

[0010] As an optimization, a rotating roller is rotatably mounted at the lower end of the trigger plate, with the axis of the roller perpendicular to the direction of bar movement. This optimization scheme converts the sliding friction between the trigger plate and the bar into rolling friction by setting the rotating roller, thus avoiding scratches on the surface of the bar.

[0011] As an optimization, the mounting bracket includes a base plate fixedly connected to the foundation platform of the skirt area, and a support tube located above the base plate and fixedly connected to the base plate via at least two columns. The rotating shaft passes through the inner hole of the support tube and is rotatably connected to the support tube via a bearing. This optimized mounting bracket structure is simple, and by setting the support tube to support the rotating shaft, the support length is increased, thus improving stability.

[0012] The beneficial effects of this utility model are as follows: by setting a trigger plate to contact the head of the bar, the head of each bar is in the same position, driving the trigger plate to rotate. The trigger plate drives the sensing plate to rotate through the rotating shaft. When the sensing plate rotates, it triggers the proximity switch, thereby triggering the steel flipping action. This realizes the steel flipping when the heads of each bar move to the same position, and finally realizes the alignment of the bar heads. This eliminates the subsequent impact alignment process and completely avoids the bending of the bar caused by impact alignment in the prior art. Attached Figure Description

[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0015] like Figure 1 The device for controlling the alignment of bar stock groups includes a mounting bracket fixed on a base platform 10 in the skirt area, and a rotating shaft 1 rotatably mounted on the mounting bracket. The axis of the rotating shaft 1 is perpendicular to the direction of bar stock movement, and the direction of bar stock movement is consistent with the axis of the bar stock. A sensing plate 6 and a trigger plate 13 extending to the front of the bar stock head are fixed on the rotating shaft. When the bar stock moves forward to the trigger plate, the head of the bar stock contacts the trigger plate and pushes the trigger plate to rotate.

[0016] In this embodiment, the trigger plate and the rotating shaft are fixedly connected by welding a bushing 2 to the upper end of the trigger plate. The bushing 2 is sleeved and fixed on the rotating shaft. The bushing and the rotating shaft can be connected by a key, or the bushing and the rotating shaft can be fixed relative to each other by setting a tightening bolt on the bushing that reaches the rotating shaft. When the trigger plate rotates, it can drive the rotating shaft to rotate.

[0017] To prevent the trigger plate from scratching the surface of the bar, in this embodiment, a rotating roller 12 is rotatably provided at the lower end of the trigger plate 13, and the axis of the rotating roller is perpendicular to the direction of bar movement.

[0018] The bar stock grouping and aligning control device in this embodiment also includes a proximity switch 7 adapted to the induction plate. In this embodiment, a YDD-A15 type inductive proximity switch is used. The proximity switch 7 is electrically connected to the actuator driving the skirt board turning mechanism. The actuator driving the skirt board turning mechanism is existing technology, and its structure will not be described in detail. Both the actuator driving the skirt board turning mechanism and the proximity switch are electrically connected to the control system. The signal input terminal of the control system is electrically connected to the proximity switch, and its control output terminal is electrically connected to the actuator driving the skirt board turning mechanism. Specifically, a mounting plate 16 is fixed to the mounting bracket. The proximity switch is mounted on the mounting plate 16. When the trigger plate rotates due to the push of the bar stock, the induction plate rotates accordingly, causing a change in the state of the proximity switch, which in turn drives the actuator driving the skirt board turning mechanism to perform the turning action.

[0019] The trigger plate 13 is tilted, and the vertical projection of the lower end of the trigger plate is in front of the vertical projection of its upper end. The vertical projection of the trigger plate 13 is in front of the vertical plane where the axis of rotation is located, and the vertical projection of the sensing plate 6 is behind the vertical plane where the axis of rotation is located. The torque generated by the trigger plate on the axis of rotation is greater than the torque generated by the sensing plate on the axis of rotation.

[0020] In order to make the trigger plate tilted in its natural state, a limiting plate 5 is fixed on the mounting bracket in this embodiment. A limiting rod 9 extending to the rotation trajectory of the sensing plate is fixed on the limiting plate 5. In this embodiment, the limiting rod extends above the sensing plate. When the rod does not contact the trigger plate, the limiting rod 9 restricts the rotation of the sensing plate 6.

[0021] In this embodiment, a support nut 14 is welded onto the limiting plate, and the limiting rod 9 passes through the support nut 14 and is connected to the support nut by a thread, which facilitates the adjustment of the axial position of the limiting rod and reduces the installation difficulty.

[0022] To facilitate adjustment of the tilt angle of the trigger plate to accommodate rods of different diameters, the sensing plate 6 in this embodiment has an arc-shaped elongated hole 15 for the limit rod 9 to pass through. The center of the arc-shaped elongated hole 15 is located on the axis of the rotating shaft, and the limit rod is connected by threads to fastening nuts 8 located on both sides of the sensing plate.

[0023] The mounting bracket includes a base plate 11 fixedly connected to the base platform 10 of the skirt area, and a support pipe 3 located above the base plate 11 and fixedly connected to the base plate by at least two columns 4. The rotating shaft 1 passes through the inner hole of the support pipe 3, and the rotating shaft is rotatably connected to the support pipe through a bearing. The limiting plate 5 and the mounting plate 16 are both welded to the outer wall of the support pipe.

[0024] In use, the device in this embodiment is located on one side of the skirt conveyor roller. When the bar moves forward to the device, the head of the bar pushes the trigger plate to rotate, and the sensing plate rotates accordingly, causing the state of the proximity switch to change. This drives the skirt flipping mechanism to perform the flipping action, thereby achieving flipping when the heads of all bars are in the same position. This achieves head alignment of the bars and ensures that all bars can be flipped into the cooling bed in the optimal position with head alignment. This fundamentally avoids bar bending caused by impact with the baffle, improves the straightness and pass rate of the product, saves the time of impact alignment, simplifies the production process, and speeds up the production pace. It also reduces defective products and lowers the maintenance costs and energy consumption of equipment (baffles, straighteners).

[0025] In actual use, three control devices of this embodiment can be set sequentially along the bar conveying direction. The three control devices are arranged at intervals of 50 meters, 80 meters and 100 meters along the bar forward direction in the skirt area, respectively, to adapt to the usage requirements of bars of different lengths.

[0026] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
