Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure processing devices, and more particularly to a rust removal device for steel structure manufacturing. BACKGROUND

[0002] Steel structure workpieces refer to structural assemblies or components manufactured using steel materials. Steel structure workpieces are commonly used in fields such as construction, bridges, ships, and mechanical equipment. After long-term storage, the outer surface of a steel structure workpiece may have many rust marks. After rusting, the strength of the workpiece may be weakened and the risk of breakage may increase. Therefore, the surface of the steel material needs to be rusted, and a rust removal device will be used.

[0003] For example, the existing patent CN114147005B provides a rust removal device for steel structure manufacturing. The first electric push rod can drive the laser emitting rod to move horizontally, and the third electric push rod can drive the laser emitting rod to move longitudinally, thereby enabling the steel material placed on the surface of the placement plate to be rusted in all directions. Compared with the past, manual operation is not required, thereby greatly saving labor and improving efficiency. Moreover, when the device is used for tubular steel materials, the fifth electric push rod is activated to drive the laser emitting rod to rotate, so that the laser emitting rod is inserted into the tubular steel material and then rotates, thereby enabling the interior of the steel material to be rusted. The device has strong adaptability and diversified functions, and compared with the past, it saves costs by using another targeted mechanism. The multiple movable rods can slide downward under the drive of the fourth electric push rod, thereby enabling the depth and position of the laser rust removal rod to be adjusted, and thereby enabling different lengths of tubular steel materials to be rusted, thereby improving the scope of application and adaptability.

[0004] However, the device still has some shortcomings in use. The laser rust removal rod used in the device cannot be bent when facing the inner wall of a curved steel material for rust removal, because the laser rust removal rod is extended and retracted by the electric push rod, and the electric push rod cannot drive the laser rust removal rod to move in a curved manner. Therefore, when facing a curved steel material, it is difficult to completely extend into the curved steel material for rust removal. Based on the above problems, we provide a rust removal device for steel structure manufacturing. SUMMARY

[0016] In summary, the present application has the following beneficial technical effects:

[0017] 1. By inserting the polishing assembly into the channel of the curved steel pipe, and fixing the polishing assembly in the channel by the moving positioning mechanism in the polishing assembly, then cooperating the external driving motor with the flexible shaft to make the polishing disc on the polishing assembly rotate in the channel and scrape the rust in the channel, and finally pushing the flexible shaft by the operator to make the polishing assembly move in the curved steel pipe, the rust in the pipe can be cleaned.

[0018] 2. By adjusting the gear shaft to rotate in the shell, and using four rack plates to synchronously move to the outside of the shell, the rollers on the horizontal bars can contact and press the inner wall of the pipe, the positioning of the shell is completed, and the stability of the shell placed in the pipe is ensured, when the flexible shaft is pushed, the shell can assist the polishing disc to move in the pipe under the action of the rollers, the rust on the inner wall of the pipe is removed, and the rack plates can be retracted to a certain extent, so that the use of different inner diameter pipes can be met to a certain extent.

[0019] 3. When the rollers contact and press the inner wall of the pipe, the rollers will move downward in the horizontal bar, at this time, the first spring on the movable rod will be retracted, and has elastic potential energy, when the shell passes through the bending part of the curved steel pipe, the rollers do not contact or less contact the inner wall of the pipe, at this time, the first spring corresponding to the rollers will be stretched to release the elastic potential energy, so as to push the rollers to contact the inner wall of the pipe, thereby ensuring the stability of the shell when passing through the bending part of the pipe.

[0020] 4. The first rotating shaft is driven by a flexible shaft, which in turn drives the second rotating shaft through two gears. The second rotating shaft rotates in the opposite direction to the first rotating shaft. The second rotating shaft drives the rotating sleeve through a belt, and the rotating sleeve rotates in the same direction as the second rotating shaft. Thus, the first rotating shaft drives the corresponding grinding disc to rotate, and the rotating sleeve drives the corresponding grinding disc to rotate, with the grinding discs on each rotating in opposite directions. This allows the grinding discs to rotate in both directions to remove rust from the inner wall of the steel pipe fitting. After the grinding disc on the first rotating shaft scrapes off the rust, the grinding disc on the rotating sleeve can reverse and scrape the scraped area again, thus ensuring the thorough removal of rust from the inner wall of the steel pipe fitting.

[0021] 5. The workpiece is placed on the processing platform and can be moved on the support panel by the electric pusher cylinder. The vertical plates on the support panel can then be inserted above the rotating roller. The protrusions on each vertical plate that can contact the workpiece will move downward, thus forming a concave surface that fits the workpiece with other protrusions. This restricts the workpiece and ensures its stability during the rust removal process. At the same time, all protrusions can be confined within the vertical plates and kept fixed. With the rotation of the ball bearings on the protrusions, the position of the workpiece can be easily adjusted and moved in all directions. Attached Figure Description
