Description

Technical Field

[0001] The utility model relates to cold-rolled steel bar production equipment, in particular to a cold-rolled steel bar feeding and turning mechanism, belonging to the technical field of steel bar production equipment. Background Art

[0002] In the production of cold-rolled rebar, vertical loading can achieve higher production speeds. This requires a loading and unloading device, which flips the coiled material from horizontal to vertical and is crucial for non-stop feeding. Current production lines use a turning device, such as the one described in Chinese Patent CN104624673A for a vertical wire rod loading system. This device is driven by dual hydraulic cylinders. The hydraulic rods of the hydraulic cylinders extend and retract, driving the turning table up and down, changing the orientation of the raw material coils. Over time, hydraulic cylinders are susceptible to leaks due to the presence of oxide scale formed on the raw material during loading and aging of the internal cylinder seals. Because the cylinders are located between the turning table and the base, replacement requires the turning table to be tilted downward, exposing the two 100 / 70-1425 cylinders. However, due to the long stroke of the cylinders, the piston rods are fully exposed when tilted downward, resulting in a long, cramped environment and difficult, time-consuming, and labor-intensive replacement. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above-mentioned problems existing in the current cold-rolled vertical feeding and turning mechanism, and to provide a cold-rolled steel bar feeding and turning mechanism.

[0004] In order to achieve the purpose of the utility model, the following technical solutions are adopted: a cold-rolled steel bar feeding and turning mechanism, including a turning table, a turning material rack fixedly connected to the turning table, the turning table is rotatably connected to the support, two arc-shaped outer gear rings are fixedly connected to the turning table, the center of the outer gear ring is concentric with the rotation axis of the turning table, a transmission shaft is rotatably installed on the side of the outer gear ring, support bearings are installed at both ends of the transmission shaft, the support bearings are located in the bearing box, the bearing box is fixedly connected to the frame, two transmission gears are fixedly connected to the transmission shaft, the two transmission gears are respectively engaged with the two outer gear rings, and the transmission shaft is fixedly connected to the output shaft of the hydraulic motor.

[0005] Furthermore, the width of the transmission gear is smaller than the width of the outer ring gear.

[0006] Furthermore, when viewed from above, the flip rack is located in the middle of the two outer gear rings.

[0007] The positive and beneficial technical effect of the utility model is that the mechanism effectively solves the problem of inconvenient maintenance and replacement of the oil cylinder of the turning device, improves work efficiency and reduces labor intensity while utilizing the existing hydraulic system. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 It is a side view schematic diagram of the present utility model. DETAILED DESCRIPTION

[0010] In order to more fully explain the implementation of the present invention, the following examples are provided. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.

[0011] The present invention is further explained in detail in conjunction with the accompanying drawings, in which the following marks are: 1: turning table; 2: turning material rack; 3: material roll; 4: shaft; 5: outer ring gear A; 6: hydraulic motor; 7: support; 8: bearing box A; 9: bearing box B; 10: transmission shaft; 11: transmission gear A; 12: transmission gear B; 13: outer ring gear B.

[0012] As shown in the attached figure, Figure 1 This is a schematic diagram of the flip rack in the horizontal position. Figure 2 This is a schematic diagram of a turning rack in a vertical position. A cold-rolled steel bar feeding and turning mechanism includes a turning platform 1, a turning rack 2 fixedly connected to the turning platform, and a material coil 3 mounted on the turning rack 2. The turning platform 1 is rotatably connected to a support 7 via an axis 4. Two arcuate outer gear rings are fixedly connected to the turning platform 1. The two arcuate outer gear rings in the figure are outer gear ring A5 and outer gear ring B13. When viewed from above, the turning rack 2 is located directly between the two outer gear rings.

[0013] The center of the outer gear ring is concentric with the rotation axis of the turning table 1. A transmission shaft 10 is rotatably installed on the side of the outer gear ring. Support bearings are installed at both ends of the transmission shaft. The support bearings are located in bearing boxes. The bearing boxes at both ends in the figure are bearing box A8 and bearing box B9 respectively. The bearing boxes are fixedly connected to the frame. Two transmission gears are fixedly connected to the transmission 10. The two transmission gears in the figure are transmission gear A12 and transmission gear B13 respectively. The two transmission gears are respectively engaged with the two outer gear rings. The width of the transmission gear is smaller than the width of the outer gear ring, which is convenient for assembly. The transmission shaft 10 is fixedly connected to the output shaft of the hydraulic motor 6.

[0014] When this mechanism is operating, the hydraulic motor rotates counterclockwise via high-pressure hydraulic oil supplied by the hydraulic control valve station. This hydraulic motor drives the drive shaft, which in turn rotates the transmission gears fixed to each end of the drive shaft. This in turn causes the two outer ring gears meshing with the gears to rotate simultaneously. The outer ring gears then drive the tilting platform and tilting rack downward. Once tilted into position, the feeder car unloads and places the raw materials on the tilting rack. The hydraulic control valve station reverses the output through the control valve, causing the hydraulic motor to rotate clockwise, causing the tilting platform and tilting rack to tilt upward, flipping the raw materials from a horizontal to a vertical position and completing the tilting process. It is common knowledge in the prior art that the hydraulic control valve station controls the forward and reverse rotation of the hydraulic motor.

[0015] After describing the implementation mode of the present invention in detail, people familiar with the technology can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention, and the present invention is not limited to the implementation mode of the examples given in the specification.
