Description

Technical Field

[0001] This utility model relates to a device for synchronously flattening fixed-length bars, belonging to the technical field of bar finishing area equipment. Background Technology

[0002] After the cold shear cuts the bars to the specified length, the bars begin the finishing process. They are conveyed to the chain bed entrance via a conveyor roller conveyor. During the conveyor roller conveyor process, the contact between each bar and the roller surface and cover plate is different, causing misalignment of the end faces. The misaligned bars need to be lifted and placed on an alignment roller conveyor arranged parallel to the conveyor roller conveyor. A fixed baffle is installed on one side of the alignment roller conveyor. The rotation of the alignment roller conveyor drives the bars to align against the fixed baffle. After realignment, the bars need to be lifted and placed on the working chain bed. The chain bed consists of chain conveyor devices spaced 1.25 meters apart. Therefore, when the bars on the alignment roller conveyor are lifted and placed on the inspection table chain bed, each set of flat supports must be kept horizontal and synchronized to ensure that the bars land smoothly on the chain bed and prevent the chain bed from tilting.

[0003] The existing bar stock flattening device consists of three shaft groups: a drive shaft, a driven shaft, and a sprocket. One sprocket is mounted on each of the drive and driven shafts, and two sprockets are mounted on the sprocket. The sprocket is connected to the drive and driven shafts via two chains to transmit motion. Due to different force conditions, the two chains stretch at different rates, causing the flattening arm to tilt during movement. This results in the bar stock falling onto the working chain bed at asynchronous times, leading to a skewed bar stock on the chain bed. Manual intervention is required to straighten the chain, significantly impacting production rhythm. Furthermore, because one side of the chain experiences greater force when the flattening arm lifts the steel, the other side of the chain is subjected to a sudden and significant impact force from the flattening arm and the bar stock when falling from a high point, causing the chain to break and halting production. Therefore, improving the existing bar stock synchronous flattening device is essential. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a synchronous flat support device for fixed-length bars. This flat support device can ensure the horizontal posture movement of the flat support arm, ensure that the bars can fall synchronously on the chain bed to achieve parallel transportation, lay the foundation for subsequent processes, improve the work quality of the processes, and ensure the normal operation of production.

[0005] The technical solution to the above technical problem is:

[0006] A synchronous flat support device for fixed-length bars includes a support frame, a drive shaft, a transition shaft, a driven shaft, a drive shaft, drive shaft bearing seats, transition shaft bearing seats, driven shaft bearing seats, drive shaft bearing seats, a drive gear, a transition gear, a driven gear, a drive sprocket, a transmission chain, a drive sprocket, a drive straight arm, a driven straight arm, and a flat support arm. The drive shaft, transition shaft, and driven shaft are arranged in parallel sequence. The drive shaft bearing seats, transition shaft bearing seats, and driven shaft bearing seats are arranged in pairs and fixed to the support frame. The two ends of the drive shaft, transition shaft, and driven shaft are rotatably connected to the corresponding drive shaft bearing seats, transition shaft bearing seats, and driven shaft bearing seats, respectively. The drive shaft bearing seats are fixed. Fixed on the lower surface of the bracket, the two ends of the drive shaft are rotatably connected to the drive shaft bearing housing respectively. The drive gear, intermediate gear, and driven gear are respectively mounted on the drive shaft, intermediate shaft, and driven shaft. The drive gear meshes with the intermediate gear and the intermediate gear meshes with the driven gear respectively. The drive sprocket and the drive sprocket are respectively mounted on the drive shaft and the drive shaft. A transmission chain is mounted between the drive sprocket and the drive sprocket. The lower ends of the two drive straight arms and the two driven straight arms are respectively mounted on the two ends of the drive shaft and the driven shaft. The two drive straight arms and the two driven straight arms are parallel to each other. The upper ends of the two drive straight arms and the two driven straight arms are rotatably connected to the middle and rear of the two flat support arms respectively.

[0007] The aforementioned synchronous flat support device for fixed-length bars comprises a support frame consisting of crossbeams, legs, and support arm beams. Legs are installed at the lower ends of two parallel crossbeams, and support arm beams are fixed parallel and vertically between the two crossbeams. Opposite drive shaft bearing seats, transition shaft bearing seats, and driven shaft bearing seats are respectively installed on the upper surfaces of the two support arm beams, and opposite drive shaft bearing seats are respectively installed on the lower surfaces of the two support arm beams.

[0008] The aforementioned synchronous flat support device for fixed-length bars comprises a horizontal support arm and two support rods. The upper ends of the two support rods are fixedly connected to the middle and rear ends of the horizontal support arm, and the lower ends of the two support rods are rotatably connected to the upper ends of the active straight arm and the driven straight arm respectively via a rotating shaft.

[0009] The beneficial effects of this utility model are:

[0010] In this invention, the drive shaft drives the active shaft to rotate via a transmission chain. The active shaft drives the transition shaft to rotate via an active gear and a transition gear. The transition shaft drives the driven shaft to rotate via a transition gear and a driven gear. The active shaft and the driven shaft drive the flat support arm to move horizontally via an active straight arm and a driven straight arm, respectively. The flat support arm performs a horizontal reciprocating lifting and lowering composite motion on the fixed-length bar.

[0011] This utility model has a simple structure and is easy to use. It can effectively ensure the horizontal movement of the flat support arm during rotation, ensuring that the fixed-length bars can be smoothly and synchronously placed on the equipment surface from the conveyor rollers to the alignment rollers and then to the inspection table chain bed. The parallel and orderly placement on the chain bed ensures the required spacing between each chain segment and improves the quality of several processes, thereby increasing the production rhythm. The gear transmission device operates continuously and stably with a long service life, reducing equipment maintenance time and improving equipment availability. Attached Figure Description
