Description

TECHNICAL FIELD

[0001] The application relates to a high-wire coil outer ring packaging line automatic hook welding device and belongs to the technical field of resistance welding. BACKGROUND

[0002] At present, after steel wire rods produced on site are wound into coils, the coils are first transferred to a packaging station through a hanging flow line, are automatically packed and bound by a plurality of steel wires or steel belts, and then are subjected to a plate hanging operation. In the prior art, whether manual plate hanging or machine plate hanging is adopted, in order to simplify steps and reduce the difficulty of technical implementation, welding and sealing of hooks are not performed after plate hanging is completed.

[0003] However, as the economic benefits of steel plants are better and better, and the process flow is more and more standardized, in order to ensure the safety of the coil plate, if the hooks are not welded and sealed, the plate is likely to be removed or replaced artificially, causing unnecessary losses.

[0006] The principle of the application is as follows: in use, the fulcrum fixing mechanism clamps the fulcrum part of the hook, the force point poking mechanism clamps the force point part of the hook, and the force point part is pulled to open the welding point part of the hook, so that the plate hanging operation is performed. After the plate hanging operation is completed, the force point poking mechanism is released, the welding point part of the hook is automatically closed, the welding driving mechanism drives the butt welding electrode to reach the welding point part, a welding operation is performed, and thus the welding and sealing of the hook are formed, so that the plate on the hook is prevented from being removed or replaced artificially.

[0017] The present application will be further illustrated in conjunction with the accompanying drawings and specific embodiments, which are only used to illustrate the present application and not to limit the scope of the present application.

[0018] A high wire coil outer ring packaging line automatic hook welding device, as shown in the accompanying Figures 1-3 , comprising a hook 1, a mounting flange 2, a fulcrum fixing mechanism 3, a force point poking mechanism 4, a welding driving mechanism 5, a butt welding electrode 6, a laser sensor 7.

[0019] As shown in the accompanying Figure 4 , the hook 1 is formed by bending a single steel wire, the first and last joints of the steel wire form a welding point 1a, the middle part forms a fulcrum 1b, and one end forms a force point 1c. In this embodiment, the steel wire is bent several times, and the overall shape is a hammer head shape. The first and last joints of the steel wire cross at the top to form the welding point 1a. The middle part is bent outward to form the fulcrum 1b. The bottom is bent into a U shape to form the force point 1c.

[0020] The mounting flange 2 is used to connect external driving, such as industrial robots.

[0021] As shown in the accompanying Figures 1-3 , the fulcrum fixing mechanism 3, the force point poking mechanism 4, and the welding driving mechanism 5 are respectively fixedly connected with the mounting flange 2. The fulcrum fixing mechanism 3 is located between the force point poking mechanism 4 and the welding driving mechanism 5, and is in alignment with the fulcrum 1b of the hook 1 for fixing the hook 1. The movable end of the welding driving mechanism 5 is fixedly connected with the butt welding electrode 6, which is in alignment with the welding point 1a of the hook 1 for welding the welding point 1a. The force point poking mechanism 4 is in alignment with the force point 1c of the hook 1 for clamping and pulling the force point 1c to open or close the welding point 1a.

[0022] The fulcrum fixing mechanism 3 specifically includes a first fixed plate 3a and a fulcrum fixing jaw 3b. The fulcrum fixing jaw 3b is connected with the mounting flange 2 through the first fixed plate 3a, and is in alignment with the fulcrum 1b of the hook 1.

[0023] The force point poking mechanism 4 specifically includes a second fixed plate 4a, a force point pushing cylinder 4b, and a force point fixing jaw 4c. The fixed end of the force point pushing cylinder 4b is connected with the mounting flange 2 through the second fixed plate 4a, and the movable end is connected with the force point fixing jaw 4c. The force point fixing jaw 4c is in alignment with the force point 1c of the hook 1 to clamp the force point 1c, and under the driving of the force point pushing cylinder 4b, the welding point 1a is opened or closed.

[0024] The welding drive mechanism 5 specifically includes a third fixed plate 5a, a lifting cylinder 5b, a butt welding cylinder 5c, and a rotating cylinder 5d. The two poles of the butt welding electrode 6 are respectively fixed to the fixed end and the movable end of the butt welding cylinder 5c. The fixed end of the lifting cylinder 5b is connected to the mounting flange 2 through the third fixed plate 5a, and the movable end is connected to the butt welding cylinder 5c through the rotating cylinder 5d. The butt welding electrode 6 reaches the welding point 1a under the drive of the lifting cylinder 5b and the rotating cylinder 5d, and clamps the welding point 1a under the drive of the butt welding cylinder 5c to perform the welding action.

[0025] The laser sensor 7 is fixed on the mounting flange 2 and faces the welding point 1a of the hook 1.

[0026] The automatic hook welding device in this embodiment consists of two stages: tag hanging and welding. During the tag hanging stage, as shown in the attached... Figure 1 As shown, the hook's fulcrum 1b is first held by the fulcrum-fixing gripper 3b, and the hook's force point 1c is held by the force point-fixing gripper 4c. Then, distance detection is performed by the laser sensor 7, and based on this detected distance, an external drive pushes the automatic hook welding device to the labeling position on the outer ring of the coiled packaging line. (The rest is as shown in the attached diagram.) Figure 2 As shown, the force-fixing jaw 4c is pulled out, causing the welding point 1a of the hook to open and engage with the outer ring of the coil packaging line. The force-fixing jaw 4c is then released, completing the entire labeling action.

[0027] During the welding process, as shown in the attached document... Figure 3 As shown, through the cooperation of the rotary cylinder 5d and the lifting cylinder 5b, the welding electrode 6 is rotated to the welding point 1a. After the welding cylinder 5c drives the two poles of the welding electrode 6 to abut and clamp the welding point 1a, the welding electrode 6 performs the welding action to complete the sealing of the welding point, thereby preventing the nameplate from being removed, lost or replaced by human intervention, and ensuring the safety of the steel information.
