Description

Technical Field

[0001] The utility model relates to the technical field of rust removal of metal products, and in particular to a rust removal tool based on 3D printing metal product processing. Background Art

[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, using powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. In the field of 3D printing, plastic materials, such as ABS and PLA, are the most widely used. Metal materials can also be used to print various metal parts.

[0003] However, since most metals have active chemical properties, they easily react with oxygen and other substances (oxidants) to become metal ions and are consumed, which can cause the outer wall of the metal product to be covered with rust. Therefore, surface rust removal is an extremely important step in the processing of metal products.

[0004] At present, the commonly used method for metal rust removal is to use electric tools to remove rust, that is, using electric brush wheels or various rust removal machines. However, this method is only suitable for large-area rust removal and is not suitable for small parts. 3D printers are limited by size, and the specifications of printed metal products are relatively small. At the same time, the shapes of metal products printed by 3D printers are relatively complex. Therefore, existing tools cannot be well applied to 3D printed metal products. It often takes a lot of time and energy to remove rust at tricky angles, which seriously affects the rust removal efficiency. In addition, more dust pollution will be caused during rust removal, which will cause harm to workers and the environment. Utility Model Content

[0047] Optionally, it is necessary to specifically explain that after the metal product is fixed, it is necessary to first spray the rust remover on the metal product, let it stand for a period of time, and then operate the rotary brushing part 5 to ensure a better rust removal effect.

When the lifting portion 6 starts to lift the base wall 51 upward, the inner baffle plate 76 is pulled out as the base wall 51 rises, so that the integrity between the base wall 51 and the bearing chassis 2 is not destroyed, and dust is further prevented from escaping, and dust is blocked as much as possible within the base wall 51 and the outer plate 75, thereby preventing a large amount of dust from floating outward and causing harm to the environment and staff. The limit strips 77 on the outer plate 75 can block the limit strips 77 on the inner baffle plate 76, so as to limit the travel of the inner baffle plate 76 and prevent the inner baffle plate 76 from falling off.

[0055] Optionally, the collecting mechanism 8 includes a connecting rod 81 connected to the bottom of the connecting block 58, and an electromagnet 82 vertically mounted at the end of the connecting rod 81.
