Description

Technical Field

[0001] The utility model relates to the technical field of metal pipelines, in particular to an unwinding mechanism for metal pipeline processing. Background Art

[0002] Metal pipes are generally made by welding metal strips after uncoiling and stripping. However, metal strips are heavy during the uncoiling process and require an uncoiling machine to complete the process.

[0003] The existing metal strip coil unwinding machine for metal pipe processing has a relatively single support point for the metal strip coil, which mainly relies on a support rod that is offset from the center of the strip coil, resulting in a large force on the support rod. After long-term use, it is inevitable that the support rod will sink and deform slightly, which affects its service life.

[0004] Based on the following drawbacks of the existing metal strip unwinding for metal pipe processing: the existing single roller support at the center of the strip coil generates a single force area and poor support stability. To this end, we propose an unwinding mechanism for metal pipe processing. Summary of the invention

[0005] The main purpose of the utility model is to provide an unwinding mechanism for metal pipe processing, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The unwinding mechanism for metal pipe processing comprises an electric slide rail, a support seat and an arc-shaped material table, and also comprises a main support roller, an auxiliary support roller and a sprocket. The top of the sliding block of the electric slide rail is equipped with a support seat by bolts, and the top of the support seat is provided with an arc-shaped material table. A U-shaped seat is welded and connected to one end of the electric slide rail, and a support rod is rotatably connected to one side of the U-shaped seat by a bearing. A servo motor is installed on the other side of the U-shaped seat by bolts, and the driving end of the servo motor is installed and connected to the rotating shaft of the support rod by a coupling.

[0008] Furthermore, lifting grooves are provided at both ends of the arc-shaped material platform, and L-shaped mounting plates are provided at the bottom of the lifting grooves. Main support rollers and auxiliary support rollers are rotatably installed on both sides of the top of the L-shaped mounting plates through bearing seats. A lower frame is welded to the bottom of the arc-shaped material platform, and a servo push rod is installed on the bottom of the lower frame through bolts. The output end of the servo push rod is fixed to the bottom of the L-shaped mounting plate, and a storage groove corresponding to the lower frame is provided on the top of the support seat.

[0009] Furthermore, a b servo motor is installed on one side of the bottom of the L-shaped mounting plate by bolts, and sprockets are installed on the driving end of the b servo motor and the rotating shaft at one end of the main support roller by key pins, and the sprockets are connected by chain sleeves.

[0010] Furthermore, hydraulic push rods are embedded at both ends of the support seat, and the output end of the hydraulic push rod is connected to the bottom of the support seat by bolts.

[0011] Compared with the prior art, the utility model has the following beneficial effects: through the assembly consisting of an electric slide rail, a support seat, an arc-shaped material table, a main support roller, an auxiliary support roller and a sprocket, the raw metal strip coil for metal pipe processing can be uncoiled, and the center and the bottom of the metal strip coil can be double-assisted supported and rotation-assisted, which increases the force points of the metal strip coil and ensures better stability in the uncoiling of the metal strip coil, solving the problem of a single force area and poor support stability caused by the existing single roller support at the center of the strip coil.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The top of the sliding block of the electric slide rail 1 is installed with the support seat 2 by bolts, and the top of the support seat 2 is provided with an arc-shaped material table 3. One end of the electric slide rail 1 is welded and connected with a U-shaped seat 5, one side of the U-shaped seat 5 is rotatably connected with a support rod 6 through a bearing, and the other side of the U-shaped seat 5 is installed with a servo motor 7 by bolts, and the driving end of the servo motor 7 is installed and connected with the rotating shaft of the support rod 6 through a coupling.

[0020] Among them, lifting grooves 10 are opened through both ends of the arc-shaped material table 3, and L-shaped mounting plates 11 are arranged at the bottom of the lifting grooves 10. The main support rollers 12 and the auxiliary support rollers 13 are rotatably installed on both sides of the top of the L-shaped mounting plate 11 through bearing seats. The bottom of the arc-shaped material table 3 is welded and connected with a lower frame 9, and a servo push rod 16 is installed on the bottom of the lower frame 9 by bolts. The output end of the servo push rod 16 is fixed to the bottom of the L-shaped mounting plate 11, and a storage groove 8 corresponding to the lower frame 9 is opened on the top of the support seat 2.

[0021] Among them, a b servo motor 14 is installed on one side of the bottom of the L-shaped mounting plate 11 by bolts, and sprockets 15 are installed on the driving end of the b servo motor 14 and the rotating shaft at one end of the main support roller 12 by key pins, and the sprockets 15 are connected by chain sleeves.

[0023] It should be noted that the utility model is an unwinding mechanism for metal pipe processing. When working, the unwinding personnel first lift the metal strip coil to be made into a metal pipe onto the arc-shaped material table 3 through the lifting mechanism of the construction site, and slide the support seat 2 horizontally through the electric slide rail 1, so that the center of the strip coil on the arc-shaped material table 3 is inserted on the support rod 6, so as to achieve preliminary support for the center of the strip coil, and the use position of the arc-shaped material table 3 is raised and lowered by the hydraulic push rod 4, and the L-shaped mounting plate 11 is pushed up by the servo push rod 16, so that the main support on the L-shaped mounting plate 11 is The support roller 12 and the auxiliary support roller 13 support the bottom of the strip coil, so that the support rod 6, the main support roller 12 and the auxiliary support roller 13 successively provide dual support for the center and the bottom of the metal strip coil, ensuring that the raw material strip coil support of the metal pipe is more stable. During the cutting process, the support rod 6 and the main support roller 12 are driven to rotate by the a servo motor 7 and the b servo motor 14 in succession, so that the support rod 6 and the main support roller 12 respectively assist in rolling the center and the bottom of the strip coil, making the metal strip cutting operation easier and avoiding the pressure of a single support point and a rotation point.
