With the continuous growth of demand for cold-rolled ribbed steel bar in the construction industry and the increasing demand for production efficiency and quality, the performance optimization of the finished product push-out mechanism becomes increasingly important. It is responsible for smoothly pushing the spool with steel bar products from the production line, so as to carry out subsequent handling, storage or further processing operations.

[0003] The traditional cold-rolled ribbed steel bar finished product push-out mechanism mostly adopts the traditional mechanical push plate structure. It is usually directly contacted with the spool by a fixed push plate connected with the power source (such as air cylinder, hydraulic cylinder, etc.). When the spool needs to be pushed out, the power source drives the push plate to move linearly, and the push plate pushes the spool by relying on the friction between them.

DETAILED DESCRIPTION

[0031] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] Refer to Figure 1 - Figure 3The utility model provides an embodiment: a kind of finished product push-out mechanism for cold-rolled ribbed steel production process, including fixed frame 1, support frame 2 is fixedly connected in the side wall of fixed frame 1, the side wall of fixed frame 1 is provided with push subassembly, fixed frame 1 and support frame 2 inside are provided with I -beam 3, the side wall of support frame 2 is provided with rotating wheel 4, the side wall of fixed frame 1 is provided with clamping subassembly;Push subassembly includes fixed block 5, fixed block 5 side wall is fixedly connected in the side wall of fixed frame 1, fixed block 5 between fixedly connected with fixed link 6, and fixed link 6 plays the role of supporting and positioning fixed plate 7, fixed link 6 side wall rotationally connects with fixed plate 7, the side wall of fixed plate 7 is fixedly connected with connecting frame 8, connecting frame 8 between fixedly connected with rotating shaft 9, rotating shaft 9 side wall rotationally connects with rotating wheel 10, and rotating wheel 10 is used to change the sliding friction between fixed plate 7 and I -beam 3 into rolling friction, the side wall of fixed frame 1 is fixedly connected with support block 11, support block 11 side wall is provided with hydraulic rod 12, and the output end of hydraulic rod 12 is connected with fixed plate 7;

[0033] After cold-rolled steel product is rolled to I -beam 3, I -beam 3 needs to be pushed out, at this time, start hydraulic rod 12, hydraulic rod 12 as power source, can provide relatively powerful and stable thrust, and its working principle is based on the transmission of liquid pressure in hydraulic system, after the hydraulic oil is pressurized by oil pump, is delivered to the cylinder of hydraulic rod 12, pushes the piston movement, and then makes hydraulic rod 12 extend, generates linear direction thrust, and hydraulic rod 12 pushes fixed plate 7, and fixed plate 7 rotates with fixed link 6 as the shaft, and fixed link 6 plays the role of supporting and positioning fixed plate 7, so that fixed plate 7 can only rotate in specific direction around its side wall, guarantee the relative stability of the direction of force and action point when pushing I -beam 3, and I -beam 3 is pushed in contact with the rotation of fixed plate 7, and rotating wheel 10 is arranged on the side wall of fixed plate 7, and rotating wheel 10 is installed on the side wall of rotating shaft 9, when fixed plate 7 pushes I -beam 3, rotating wheel 10 contacts with I -beam 3 and starts to rotate, and the existence of rotating wheel 10 changes the sliding friction between fixed plate 7 and I -beam 3 into rolling friction, and the rolling friction coefficient is far less than the sliding friction coefficient, and the change of this friction mode greatly reduces the force required to push I -beam 3, so that the whole pushing-out process is more smooth and efficient, and simultaneously, due to the reduction of friction, the wear of fixed plate 7 and I -beam 3 in the contact process is also significantly reduced, which not only prolongs the service life of fixed plate 7 and I -beam 3, reduces the maintenance cost and replacement frequency of equipment, but also helps to guarantee the stability of I -beam 3 in the pushing-out process, avoids the phenomenon of uneven or jamming caused by wear, thereby improves the overall quality and reliability of the pushing-out process after cold-rolled steel product is rolled to I -beam 3.

[0034] Refer to Figure 1 Figure 3 ​The clamping assembly comprises a connecting plate 13 fixedly connected to the side wall of the fixing frame 1, a sliding rail 14 fixedly connected between the connecting plates 13, a supporting plate 15 slidingly connected to the side wall of the sliding rail 14, a fixed ring 16 fixedly connected between the supporting plates 15, a fixed frame 17 rotatably connected to the side wall of the fixed ring 16, an arc groove 18 formed in the fixed frame 17, a connecting frame 19 arranged in the arc groove 18, a sliding plate 20 slidingly connected in the connecting frame 19, the sliding plate 20 rotatably connected to the side wall of the fixed ring 16, a roller 21 rotatably connected in the sliding plate 20, the roller 21 enabling the reinforcing steel bar to more smoothly enter the clamping assembly and wind around the spool 3, a connecting block one 23 rotatably connected to the side wall of the fixed frame 17, a connecting block two 24 rotatably connected to the side wall of the fixed ring 16, and a screw rod 22 rotatably connected in the connecting block two 24, the screw rod 22 serving as a transmission component, and the connecting block one 23 threadedly connected to the side wall of the screw rod 22.

[0035] The reinforcing steel bar needs to pass through the clamping assembly when winding on the spool 3, and the clamping assembly has the function of clamping reinforcing steel bars of different sizes. The rotating block is an operating component, and the rotating force applied from outside can be transmitted to the screw rod 22 by rotating the rotating block. The screw rod 22 serves as a transmission component, and its rotation can convert rotary motion into linear motion. When the screw rod 22 rotates, the connecting block one 23 moves on the side wall of the screw rod 22. The connecting block one 23 serves as a connection and transmission component, and it transmits the linear motion of the screw rod 22 to the fixed frame 17. The fixed frame 17 rotates under the drive of the connecting block one 23, and the rotation of the fixed frame 17 changes the spatial posture of the connecting frame 19. The sliding plate 20 is arranged in the connecting frame 19. Due to the rotation of the fixed frame 17, the sliding plate 20 moves in the connecting frame 19, thereby changing the distance between the sliding plates 20. Such a design can adapt to reinforcing steel bars of different diameters. For thinner reinforcing steel bars, the distance between the sliding plates 20 can be reduced to achieve close clamping. For thicker reinforcing steel bars, the distance can be increased to accommodate them. Meanwhile, the roller 21 is rotatably arranged in the sliding plate 20. The main function of the roller 21 is to reduce the friction between the reinforcing steel bar and the clamping assembly. When the reinforcing steel bar moves between the sliding plates 20, the roller 21 rotates with the movement of the reinforcing steel bar, which enables the reinforcing steel bar to more smoothly enter the clamping assembly and wind around the spool 3. The clamping assembly enables the reinforcing steel bar to maintain a stable position and posture during the winding process on the spool 3, avoiding shaking and deviation of the reinforcing steel bar, and ensuring that the reinforcing steel bar can be uniformly and closely wound on the spool 3, thereby improving the quality and precision of the reinforcing steel bar winding.

[0036] Working principle: after the cold rolled steel finished product is wound on the spool 3, the hydraulic rod 12 is started to push the fixed plate 7, the fixed plate 7 rotates on the side wall of the fixed rod 6, and the fixed plate 7 is pushed by the spool 3 in contact with the fixed plate 7, the side wall of the fixed plate 7 is provided with the rotating wheel 10, and the rotating wheel 10 rotates on the side wall of the rotating shaft 9 in contact with the spool 3, thereby reducing the force and reducing the wear.

[0037] The steel bar needs to pass through the clamping assembly when winding on the spool 3, in order to clamp different sizes of steel bars, the screw rod 22 is rotated by rotating the rotating block, and the connecting block one 23 moves on the side wall of the screw rod 22, and the movement of the connecting block one 23 makes the fixed frame 17 rotate, the rotation of the fixed frame 17 makes the sliding plate 20 in the connecting frame 19 move, thereby changing the distance between the sliding plates 20, and the rollers 21 rotate in the sliding plates 20, which makes the steel bar more smoothly enter the clamping assembly and wind on the spool 3.

[0038] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the protection scope of the present application.
