Description

Technical Field

[0002] By shooting steel sand at the steel surface at high speed, floating rust can be effectively removed. In fact, sandblasting is not only to remove rust, it also makes the surface of steel components rough and increases friction, which plays a certain role in improving structural stability. Since manual rust removal is inefficient and ineffective, steel structure factories are usually equipped with sandblasting equipment. Therefore, when it is necessary to ensure the quality of steel surface treatment and improve structural performance, sandblasting is an indispensable step.

[0003] Through sandblasting, dirt, scale, welding slag and other impurities on the steel pipe wall can be removed, so that the inner wall surface of the steel pipe presents the original color of the metal and reduces the internal surface stress. This can effectively increase the service life of the steel pipe, reduce the internal corrosion of the steel pipe, and thus improve the internal and appearance quality of the steel pipe.

[0004] At present, the sandblasting process for steel pipes is well developed, and automatic machinery can also be used to send the steel pipes into the sandblasting machine. In the existing technology, the steel pipes on the storage rack can be dialed into the working position by the automatic machinery, and the workpiece will work automatically after it is in place. However, the steel pipes on the storage rack still need to be placed manually, which only alleviates the time pressure of manually placing the steel pipes.

[0093] Initially, the two platforms 603 are adapted to fit the bottom plate 301 .

[0094] The working principle of the present invention is as follows:

[0095] First, the sealing chamber components in front and behind the sandblasting chamber components are opened, and the moving assembly slides along the slide rail 204 to the top of the loading platform 108 to wait for the steel pipe to be poured onto the outer roller mechanism 4. After the steel pipe is in place, the sealing chamber components in front and behind are closed, and the steel pipe starts to rotate on the moving assembly. The sandblasting machine on the guard plate 102 and the inner sandblasting assembly perform sandblasting treatment on the steel pipe inside and outside respectively. After the sandblasting cleaning is completed, the cleaned steel pipe is withdrawn, and the moving assembly slides along the slide rail 204 to the unloading platform 203, and the steel pipe automatically rolls to the unloading platform, thereby completing a working cycle.

[0096] The moving assembly slides along the slide rail 204 to the top of the loading platform 108, waiting to pour the steel pipe to be processed onto the outer roller mechanism 4. Due to the loose state of the second belt 7, the steel pipe poured onto the moving assembly will automatically slide into the adjacent first roller 401 and second roller 501 for stacking. If there is a problem with the accumulation of steel pipes, the cylinder 508 is retracted to move the inner roller mechanism 5 downward, thereby tightening the loose second belt 7 from the bottom. At this time, the upper layer of the second belt 7 is tightened into a plane. The first motor 403 is started to rotate and drive the second belt 7 to rotate, thereby separating and adjusting the accumulated steel pipes. After the inner roller mechanism 5 is restored to its state, the steel pipes can be reasonably stacked between the first roller 401 and the second roller 501. The stacking operation of the steel pipes can be automatically performed, which is convenient for locating the position of the steel pipes and improving the accuracy of subsequent sandblasting.

[0097] Slide the moving assembly along 304 to send the steel pipe into the sandblasting chamber assembly, then slide the inner sandblasting assembly along 304 into the sandblasting chamber assembly, close the movable doors 107 of the sealing chamber assemblies on both sides, and sandblast the outer wall of the steel pipe through the sandblasting machine on the guard plate 102. In addition, the sand pipe 208 corresponding to the sand pipe inserted into the steel pipe is sandblasted by the spray gun 209 sliding on the outside of the sand pipe 208, so that the inner and outer walls of the steel pipe are sandblasted simultaneously, thereby improving the sandblasting efficiency.

[0098] During the sandblasting process, the first motor 403 and the second motor 506 are started, and the steel pipe is driven to rotate by the fit between the steel pipe and the first roller sleeve 402 and the second roller sleeve 502, thereby improving the uniformity and comprehensiveness of the sandblasting process.

[0099] When the steel pipe is dumped during the loading stage, the third motor 605 is started to flip the swing table 603 upward (such as Fig.12 As shown), the steel pipe poured into the moving component can be blocked and connected to avoid problems such as the steel pipe slipping, thereby improving the safety of feeding.

[0100] During the sandblasting process, the third motor 605 is started to flip the swing table 603 downward (as shown in FIG. Fig.10 As shown), the space between the bottom plate 301 and the outer roller mechanism 4 and the inner roller mechanism 5 can be closed by the swing table 603, reducing the situation where sandblasting invades the interior of the moving component, thereby reducing the trouble of cleaning the sandblasting, extending the service life, and facilitating maintenance and cleaning.

[0101] When the sandblasting is completed and the material needs to be unloaded, first the inner sandblasting assembly is withdrawn and moved back into the auxiliary bin assembly along 304, and then the moving assembly is slid onto the unloading table 203 along 304. At this time, the third motor 605 is started to flip the swing table 603 to a tilted downward state (such as Fig.11As shown), the cylinder 508 is then retracted to straighten the second belt 7, and the first motor 403 is started to rotate to drive the second belt 7 to move, so that the steel pipe is automatically transported out, and the loading and unloading of the steel pipe can be automatically completed, thereby improving the automation performance.

[0102] The tilted and flipped swing table 603 can guide the unloading of the steel pipe, thereby improving the accuracy of unloading the steel pipe and enhancing the protection of the steel pipe.

[0103] By sandblasting the inside and outside of the steel pipe, the corrosion resistance of the workpiece and metal materials can be effectively improved, the adhesion strength of the coating on the metal surface can be improved, the corrosion resistance of the steel pipe can be improved, the service life of the steel pipe can be extended, the process of the workpiece surface can be optimized, and the quality of the steel pipe can be effectively improved.

[0104] The slide rail 204 is supported by the support legs 205 in the sandblasting chamber assembly, so that the sandblasting can remain at the bottom of the slide rail 204, reducing the incidence of its accumulation on the slide rail 204. In addition, by setting the slopes 303 at both ends of the second slide seat 302, when the second slide seat 302 slides along 304, the sandblasting that falls on 304 can be scraped off in advance, and by the M-shaped setting of the upper surface of 304, the scraped sandblasting can slide out to both sides of 304, thereby improving the smoothness of the operation of the moving assembly.

[0105] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
