Description

Technical Field

[0001] The invention relates to the technical field of sheet metal processing, in particular to a surface rust removal device for sheet metal processing. Background Art

[0002] Sheet metal parts are products processed by sheet metal technology, and they are indispensable in our lives. Sheet metal parts are made by filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending, die forging, and water jet cutting. Sheet metal parts are made of metal materials. If they are not stored properly, the surface of the sheet metal parts will rust, affecting the use of the sheet metal parts. Therefore, when processing the preserved sheet metal parts, it is necessary to first use a rust removal device to remove the rust on the surface of the sheet metal parts.

[0003] Due to the different shapes of sheet metal parts, a drum-type ultrasonic rust remover is currently commonly used to remove rust from sheet metal parts. The efficiency of rust removal on sheet metal parts is improved by the high-frequency vibration of the ultrasonic rust remover and the rotation of the drum. However, in order to prevent the rust remover in the ultrasonic cleaning tank from being thrown out, the rotation speed of the drum is usually relatively low, so it is difficult to make the sheet metal parts in the drum roll and disperse quickly, resulting in a large number of sheet metal parts inside the drum being attached to each other under the action of the rust remover when the drum rotates. Therefore, the two attached sheet metal surfaces cannot achieve rapid rust removal. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-9 In an embodiment of the present invention, a surface rust removal device for sheet metal processing includes an ultrasonic rust removal machine 1, a roller 2, two driving mechanisms 3, two spraying mechanisms 4, a lifting mechanism 5 and two drying mechanisms 6. The ultrasonic rust removal machine 1 and the roller 2 arranged inside are mainly used to improve the rust removal efficiency of the sheet metal;

[0039] Two driving mechanisms 3 are slidably connected to the two ends of the ultrasonic rust remover 1, and mainly drive the roller 2 to drive the sheet metal parts inside it to roll, so as to accelerate the flow of the rust remover inside the ultrasonic rust remover 1, so that the rust remover can quickly dissolve the rust spots on the sheet metal parts;

[0040] Two spray mechanisms 4 are embedded and fixed on both sides of the ultrasonic rust remover 1, and are mainly used to suck the rust remover in the ultrasonic rust remover 1 into the spray mechanism 4, and then spray it out in the form of a water column. The sprayed water column can hit the sheet metal parts in the drum 2, so that the sheet metal parts are turned over or the sheet metal parts that are attached to each other are spread out;

[0041] The lifting mechanism 5 is arranged inside the ultrasonic rust remover 1, and is mainly used to lift the drum 2 to a certain height to remove the rust remover in the ultrasonic rust remover 1, so that the sheet metal parts in the drum 2 can be drained;

[0042] Two drying mechanisms 6 are fixedly connected between the two ends of the ultrasonic rust remover 1 and are mainly connected to an external hot air blower to quickly dry the sheet metal parts entering the drum 2 .

[0043] Specifically, firstly, the drum 2 is taken out from the interior of the ultrasonic rust remover 1, and then a certain amount of rust remover is added into the interior of the ultrasonic rust remover 1, and the sheet metal parts to be rusted are placed into the interior of the drum 2, and then the drum 2 with the sheet metal parts is placed into the interior of the ultrasonic rust remover 1 through the lifting equipment, and the drum 2 is located on the lifting mechanism 5, and then the two driving mechanisms 3 are connected to the drum 2, and the drum 2 is driven to rotate by the two driving mechanisms 3. The rotating drum 2 can drive the sheet metal parts inside it to roll, and at the same time, the rotation of the drum 2 can pour a part of the rust remover into the two injection mechanisms 4, and then the rust remover is sprayed on the sheet metal parts in the drum 2 in the form of a water column through the injection mechanism 4. Since the rotation of the drum 2 will drive the sheet metal parts to roll, and then the water column impacts the sheet metal parts, the sheet metal parts in the drum 2 are turned over and the sheet metal parts that are attached to each other are washed away, so that the surface of the sheet metal parts can be completely immersed in the rust remover, so that the rust on the surface of the sheet metal parts can be removed more quickly. The rust spots are dissolved. When the rust spots on the surface of the sheet metal are completely dissolved, the lifting mechanism 5 lifts the drum 2 and the two driving mechanisms 3 to a certain height (the drum 2 is separated from the rust remover), and then the two driving mechanisms 3 drive the drum 2 to rotate again. At the same time, the two drying mechanisms 6 blow the hot air generated by the externally connected hot air blower to the sheet metal in the drum 2 to accelerate the drying of the sheet metal. When the sheet metal in the drum 2 is dried, the drum 2 is removed from the ultrasonic rust remover 1 again by the hoisting equipment, and the lifting mechanism 5 is restored to its original position. The device allows a part of the rust remover to be poured into the two injection mechanisms 4 through the rotation of the drum 2, and then the rust remover is sprayed on the sheet metal in the drum 2 in the form of a water column through the injection mechanism 4. Then, through the rotation of the drum 2 and the impact of the water column, the sheet metal in the drum 2 is turned over and the sheet metal parts that are attached to each other are washed away, so that the surface of the sheet metal can be completely immersed in the rust remover, thereby dissolving the rust spots on the surface of the sheet metal more quickly.

A liquid inlet pipe 44 that is fixed through the bottom of the ultrasonic rust remover 1 is fixed through one end of the sleeve 43, and a liquid outlet pipe 45 that is fixed through the inside of the rectangular shell 41 at a corresponding position is fixed through one end of the sleeve 43.

The sprayed water column impacts the sheet metal in the drum 2, and the sheet metal rolls under the rotation of the drum 2. Combined with the impact of the water column, the sheet metal can be turned over or the sheet metal parts that are attached to each other can be dispersed, so that the surface of the sheet metal can be completely immersed in the rust remover, thereby achieving faster rust removal of the sheet metal.

The rotating drum 2 can flip the sheet metal parts inside it, so that the rust remover can better remove rust from the sheet metal parts.

[0050] Embodiment 3

A double-axis motor 57 is fixedly connected to one end face of the ultrasonic rust remover 1, and the two output ends of the double-axis motor 57 are respectively fixedly connected to the worm 56 at the corresponding positions. Both sides of the two end faces inside the ultrasonic rust remover 1 are fixedly connected to limit plates 15, and a spherical groove is provided on the side of the limit plate 15. Both ends of one side of the connecting plate 51 are fixedly connected to connecting rods 58, and one end of the connecting rod 58 is fixedly connected to a ball 59 that slides and engages with the spherical groove at the corresponding position. The tops of the two ends of the two opposite side faces of the ultrasonic rust remover 1 are fixedly connected to a connecting frame 16, and the outer wall of the connecting frame 16 is penetrated by a pulley 17 that slides and abuts against the pull rope 54 at the corresponding position.

[0052] In this embodiment, the drum 2 with the sheet metal parts is placed between the two brackets 52 by using the lifting equipment, and the bracket 52 is located between the two limit rings 22, and then the drum 2 can be rotated between the two brackets 52 by the two driving mechanisms 3.
