Abstract
Description
Technical Field
[0001] This invention relates to the field of rust removal technology for electric hammer drill bits, specifically a rust removal device for the surface of hardware electric hammer drill bits. Background Technology
[0002] A hammer drill is an electrically powered rotary hammer drill with a safety clutch and a pneumatic hammering mechanism. It works by using a piston to compress gas and impact the drill bit, requiring minimal manual force. It can drill holes 6-100mm in hard materials such as concrete, brick, and stone, and is highly efficient at drilling in these materials. However, it cannot drill holes in metal.
[0003] Different types of drill bits are often required during use. These bits are prone to rust during storage, leading to a reduction in their lifespan. Therefore, rust prevention treatment is necessary. The quality of rust prevention largely depends on the adhesion of the rust-preventive paint to the surface, and the adhesion itself depends on the quality of rust removal on the pipe surface. In other words, among factors such as rust removal quality, anti-corrosion layer thickness, and type, rust removal quality has the greatest impact on drill bit lifespan. Therefore, rust removal quality must be given high priority. Current rust removal techniques commonly use manual wire brushes and sandpaper, which are inefficient, labor-intensive, and severely impact production, reducing economic benefits.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] Example:
[0027] like Figure 1-6As shown, this embodiment of the invention provides a rust removal device for the surface of a metal electric hammer drill bit, including a rust removal mounting cylinder 1. A first conical head 2 is rotatably connected to one end of the rust removal mounting cylinder 1 in a sealed manner. A second conical head 3 is fixedly connected to the end of the first conical head 2 away from the rust removal mounting cylinder 1. A sealing ring is provided inside the second conical head 3 to ensure the sealing performance when it is sleeved with the electric hammer. Multiple sets of fixing components arranged in a ring array are installed on the outer surface of the second conical head 3. The fixing components include a fixing mounting block 4 fixedly connected to the outer surface of the second conical head 3. A transverse connecting plate 5 is fixedly connected to one side of the fixing mounting block 4. A threaded rotating shaft 6 is threaded through and threadedly connected to the surface of the transverse connecting plate 5. A fixing rotating block 7 is fixedly connected to one end of the threaded rotating shaft 6, and a limit clamping block 8 is fixedly connected to the other end of the threaded rotating shaft 6.
[0028] The other end of the rust removal mounting cylinder 1 is fixedly connected to a threaded retaining ring 9. The inner wall of the threaded retaining ring 9 is threadedly connected to a surface cleaning component. The surface cleaning component includes a rotating mounting disk 10 threadedly connected inside the threaded retaining ring 9. Four connecting long straight bars 12 arranged in a circular array are fixedly connected to one side of the rotating mounting disk 10. A fixed brush body 13 is fixedly connected to the surface of the connecting long straight bars 12. A rotating horizontal plate is fixedly connected to the other side of the rotating mounting disk 10. An arc-shaped connecting block 11 is fixedly connected to the side of the rotating horizontal plate away from the rotating mounting disk 10.
[0029] A connecting mounting base 16 is fixedly connected to the outer surface of the rust removal mounting cylinder 1. A mounting positioning component is connected to the bottom of the connecting mounting base 16. The mounting positioning component includes a U-shaped snap-fit seat 17 fixedly connected to the bottom of the connecting mounting base 16. A movable mounting strip 20 is provided on the inner side of the U-shaped snap-fit seat 17. A threaded fixing shaft 22 is threadedly connected between the movable mounting strip 20 and the U-shaped snap-fit seat 17. A sleeve assembly is provided at the other end of the movable mounting strip 20. The sleeve assembly includes a sleeve ring 18. A rectangular mounting piece 19 is fixedly connected to the outer surface of the sleeve ring 18. The movable mounting strip 20 is located away from the U-shaped snap-fit seat 17. One end of the seat 17 is rotatably connected to the side wall of the rectangular mounting plate 19. The outer surface of the sleeve ring 18 is threaded with a locking bolt 23. The sleeve ring 18 is placed on the handle of the electric hammer, and the locking bolt 23 is manually tightened so that the locking bolt 23 abuts against the handle of the electric hammer, thereby fixing the sleeve ring 18 on the handle of the electric hammer. Then, the movable mounting strip 20 is rotated to rotate into the inside of the U-shaped clamp seat 17. The movable mounting strip 20 is threadedly connected to the U-shaped clamp seat 17 through the threaded fixing shaft 22. At this time, the installation of the rust removal mounting cylinder 1 is completed.
[0030] Both the movable mounting strip 20 and the U-shaped snap-fit seat 17 have through-holes 21 corresponding to the threaded fixed shaft 22. The outer surface of the rust removal mounting cylinder 1 is fixedly connected to the rust remover adding tube 14. A rubber sealing plug 15 is inserted inside the rust remover adding tube 14. Four fixed brush bodies 13 are arranged in a ring array and are located inside the rust removal mounting cylinder 1. The rubber sealing plug 15 is opened, and rust remover is added into the rust removal mounting cylinder 1 through the rust remover adding tube 14. Then the electric hammer switch is turned on. After the electric hammer is started, it rotates with the drill bit, so that the drill bit is continuously rotated and soaked in the rust remover. At the same time, the drill bit is in continuous contact with the fixed brush body 13, and the rust on the drill bit is cleaned by the fixed brush body 13.
[0031] Working principle:
[0032] When in use, the second conical head 3 is fitted onto the sliding sleeve of the electric hammer (the sliding sleeve is an important part of the electric hammer when the drill bit is clamped. When the electric hammer is started, the sliding sleeve and the drill bit rotate together). Then, the rotating block 7 is rotated to rotate the threaded rotating shaft 6, so that the threaded rotating shaft 6 moves while rotating, so that the four limit clamping blocks 8 clamp the sliding sleeve of the electric hammer.
[0033] Next, place the sleeve ring 18 onto the handle of the electric hammer and manually tighten the locking bolt 23 so that the locking bolt 23 abuts against the handle of the electric hammer, thereby fixing the sleeve ring 18 onto the handle of the electric hammer. Then rotate the movable mounting strip 20 to rotate it into the U-shaped retaining seat 17. Connect the movable mounting strip 20 and the U-shaped retaining seat 17 by threaded fixing shaft 22. At this point, the installation of the rust removal mounting cylinder 1 is completed. Then connect the rotating mounting plate 10 to the threaded fixing ring 9. The fixed brush body 13 is located inside the rust removal mounting cylinder 1. Then open the rubber sealing plug 15 and add rust remover into the rust removal mounting cylinder 1 through the rust remover adding tube 14. Then turn on the electric hammer switch. After the electric hammer starts, it rotates with the drill bit, so that the drill bit is constantly rotating and soaking in the rust remover. At the same time, the drill bit is constantly in contact with the fixed brush body 13, and the fixed brush body 13 cleans the rust on the drill bit.
[0034] After the drill bit is cleaned and rust removed, remove the rotating mounting plate 10, pour out the rust remover, and then remove the rust removal mounting cylinder 1.
