Description

Technical Field

[0001] The utility model relates to the technical field of profile pre-processing equipment, in particular to an automated device for profile pre-processing. Background Art

[0002] Hot-dip galvanizing is a common method for steel surface treatment. Its main steps include pre-treatment, hot-dip galvanizing and post-treatment. Pre-treatment includes degreasing, pickling, plating assistance, etc. Pre-treatment is an important part of the hot-dip galvanizing process, mainly to provide clean workpieces for hot-dip galvanizing so that the steel substrate surface and molten zinc can fully react. Pre-treatment equipment is one of the key equipment in the hot-dip galvanizing production line, and its performance directly affects the pre-treatment effect and production efficiency.

[0003] The existing profile pre-treatment production process generally uses workshop cranes and slings to lift bundled profiles, and manually immerses them in different pre-treatment process tanks to complete the degreasing, pickling, rinsing, and plating processes in sequence.

[0004] However, the existing pre-treatment equipment still has some problems and shortcomings in actual use. First, the existing lifting equipment needs to be manually controlled when completing the pre-treatment process, which has disadvantages such as harsh environment, low work efficiency, and high safety risks. Secondly, during the process of lifting and unloading materials, the profile may slip due to vibration or other reasons, causing production accidents. In addition, when draining the treatment liquid in the steel pipe, it is often not completely drained, which not only wastes the treatment liquid, but also may affect the subsequent hot-dip galvanizing process.

[0008] A downward pressing structure of downward pressing profiles is installed in the frame;

[0009] The frame is provided with a power mechanism for driving the rotating arm mechanism and the pressing structure to work synchronously.

[0012] Preferably, the transmission mechanism comprises a driven gear mounted on the outside of the rotating arm, a toothed plate is mounted on the outside of the moving crossbeam, and the driven gear and the toothed plate are meshingly connected.

[0013] Preferably, the downward pressing structure includes a downward pressing sleeve fixed on the movable crossbeam and a downward pressing guide rod hinged on the frame. The downward pressing guide rod passes through the inner side of the downward pressing sleeve and drives the downward pressing guide rod to swing as the downward pressing sleeve moves. The lower end of the downward pressing guide rod is hinged with a downward pressing plate.

[0014] Preferably, the frame is provided with lifting rings mounted on the frame.

[0015] After adopting the above structure, the utility model has the following advantages:

[0016] The utility model can control the closing of the rotating arm mechanism through the power mechanism, and at the same time, the downward pressure structure presses the profile, which can effectively solve the problem of profile slipping that may occur in the process of lifting and unloading materials in the existing equipment, and improve production safety; secondly, the device can timely remove impurities generated by pre-treatment, ensure the pre-treatment effect, and extend the service life of the treatment liquid; finally, the device can completely drain the treatment liquid in the profile, avoid the waste of treatment liquid, and improve the efficiency of the subsequent hot-dip galvanizing process.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] The utility model is further described in detail below in conjunction with the full text.

[0027] Combined with Figure 1-Figure 3 , an automated device for pre-processing a profile, comprising a frame 1, a power mechanism 6, a transmission mechanism 5, a rotating arm mechanism 2 and a pressing structure 3. The frame 1 is provided with a power mechanism 6, a plurality of rotating arm mechanisms 2 are arranged on both sides of the frame 1, the power mechanism 6 is connected to the rotating shaft of the rotating arm mechanism 2 through the transmission mechanism 5, and the pressing structure 3 is located below the frame 1, connected to the transmission mechanism 5 and moves synchronously.

[0028] Specifically, multiple groups of rotating arm mechanisms 2 capable of closing and separating the profiles are symmetrically (including offset) installed on both sides of the frame.

[0029] When the utility model is implemented, Figure 1 and Figure 3 As shown, the power mechanism 6 includes a telescopic rod 601 installed on the frame 1, a moving beam 602 is installed at the telescopic end of the telescopic rod 601, one end of the telescopic rod 601 is fixed on the frame 1, and the telescopic rod 601 can drive the moving beam 602 to move left and right.

[0030] Of course, not limited to the above structure, the power mechanism 6 can also adopt the following structure. The power mechanism 6 can also be set as a screw mechanism. The driving motor of the screw mechanism is installed on the frame 1, and a screw is installed on the output end of the driving motor. A ball slider used in conjunction with the screw is installed on the moving beam 602. At the same time, a limit column for limiting the movement of the moving beam 602 is installed on the frame 1, and the moving beam 602 is driven to move left and right through the screw mechanism.

[0031] A transmission mechanism 5 is installed between the power mechanism 6 and the rotating arm mechanism 2, and the power mechanism 6 drives the rotating arm mechanism 2 to close and separate through the transmission mechanism 5. The rotating arm mechanism 2 includes a fixed frame 201 installed on the side of the frame 1, and a rotating arm 202 is installed on the bearing inside the fixed frame 201. The power mechanism 6 controls the rotation of the rotating arm mechanism 2 through the transmission mechanism 5, driving the rotating arm 202 to close and separate, so that the hanger can lift and unload materials.

[0032] The pressing structure 3 includes a pressing sleeve 301 fixed on the moving crossbeam 602 and a pressing guide rod 302 hinged on the frame 1. The pressing guide rod 302 passes through the inner side of the pressing sleeve 301 and drives the pressing guide rod 302 to swing as the pressing sleeve 301 moves. The lower end of the pressing guide rod 302 is hinged with a pressing plate 303. When the rotating arm 202 is closed, the transmission mechanism 5 drives the pressing structure 3 to fall, and the pressing plate 303 presses the profile to prevent it from slipping. This design can effectively prevent the profile from slipping during the process of lifting and unloading, and avoid the occurrence of production accidents.

[0033] During the pre-treatment process, the power mechanism 6 controls the arm mechanism 2 to close and the pressing structure 3 to press the profile, so that the hanger can move up and down in the pre-treatment process tank, thereby achieving degreasing, pickling, rinsing, plating, etc. of the profile. At the same time, the frame 1 is relatively installed with a lifting ring 4. By controlling the height of the two lifting rings 4, an inclination angle is generated, so that the hanger is tilted, the treatment liquid in the profile can be discharged, and impurities generated by the pre-treatment can be removed, the pre-treatment effect is improved, and the service life of the treatment liquid is extended.

[0034] After the pre-treatment is completed, the power mechanism 6 controls the arm mechanism 2 to close, so that the hanger can lift the profile out of the pre-treatment process tank. At the same time, the downward pressure structure 3 presses the profile to prevent it from slipping. The inclination angle of the hanger is controlled to completely drain the treatment liquid in the profile to save the treatment liquid and improve the efficiency of the subsequent hot-dip galvanizing process.

[0035] Multiple sets of rotating arm mechanisms 2 for closing and separating profiles are mirror-mounted on both sides of the frame 1;

[0036] The frame 1 is provided with a power mechanism 6 for driving the rotating arm mechanism 2 and the pressing structure 3 to work synchronously;

When the moving beam 602 moves, the toothed plate 502 is driven to move, thereby driving the driven gear 501 to rotate, so that the rotating arm 202 rotates, achieving the effect of closing and separating the two rotating arms 202.

[0038] When the utility model is implemented, Figure 1 , Figure 2 and Figure 4 As shown, a pressing structure 3 for pressing down the profile is installed in the frame 1, and the pressing sleeve 301 is fixed on the moving beam 602. The pressing guide rod 302 can slide up and down in the pressing sleeve 301. A limit plate is provided on the moving beam 602, and the pressing guide rod 302 is hinged by the pressing rotating shaft. The power mechanism 6 drives the moving beam 602 to move left and right, and the pressing sleeve 301 moves left and right together with the moving beam 602, driving the pressing guide rod 302 to swing left and right through the limit of the pressing sleeve 301 and the hinge of the pressing rotating shaft, driving the pressing plate 303 to rise or fall, and the pressing plate 303 descends to press the profile, preventing the profile from slipping during the lifting and unloading process to avoid production accidents.

[0039] The working principle of this utility model:

[0040] When the power mechanism 6 is working, the arm mechanism 2 can be controlled to close through the power mechanism 6, and the pressing structure 3 works at the same time, driving the movable beam 602 to move left and right, and the pressing sleeve 301 moves left and right together with the movable beam 602, driving the pressing guide rod 302 to swing left and right through the limit of the pressing sleeve 301 and the hinge of the pressing rotating shaft, driving the pressing plate 303 to rise or fall, and the pressing plate 303 descends to press the profile, so that the hanger can lift the profile out of the pre-treatment process tank, and at the same time, the pressing structure 3 presses the profile to prevent it from slipping, and controls the inclination angle of the hanger to completely drain the treatment liquid in the profile, so as to save the treatment liquid and improve the efficiency of the subsequent hot-dip galvanizing process.

[0041] The above describes the utility model and its implementation methods, which is not restrictive. What is shown in the full text is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
