[0002] Rebars may rust during transportation and storage, which may affect their use. Therefore, it is necessary to remove rust from the rusted rebars. The industry usually uses rebar rust removal devices to remove rust from rebars. Existing rebar rust removal devices can only be used for rebars with fixed pitch and fixed diameter. In addition, there may be irregular protrusions and burrs on the surface of the rebar, which may cause the rust removal device to fail to contact the rebar surface, affecting the quality of rust removal. Summary of the invention
[0003] The utility model aims to provide an efficient threaded steel bar rust removal device, which can adapt to threaded steel bars with different pitches and different diameters.
[0004] In order to achieve the above-mentioned purpose, the utility model provides an efficient threaded steel rust removal device, specifically:
[0005] The invention comprises a chemical rust removal mechanism, which comprises a rust removal part, which comprises a rust removal shell with a liquid inlet on the top and a rust removal sponge in the rust removal shell, wherein the rust removal sponge has a channel for the threaded steel bar to pass through the rust removal sponge along the axis, and openings with a diameter larger than the diameter of the rust removal sponge channel opening are formed at both ends of the rust removal shell at positions corresponding to the channel opening of the rust removal sponge, and the rust removal sponge is soaked in a chemical rust removal liquid;
[0006] The invention comprises a clamping mechanism, which clamps one end of the threaded steel bar, and a rust removal sponge faces a passage opening of the clamping mechanism for the other end of the threaded steel bar to extend into; the chemical rust removal mechanism and the clamping mechanism move relatively close to each other, so that various places of the threaded steel bar pass through the rust removal sponge and react with the chemical rust removal liquid in the rust removal sponge to achieve rust removal.
[0007] Furthermore, the chemical rust removal mechanism includes a wiping portion with a wiping sponge inside, and the wiping sponge has a channel along the axis for the threaded steel to cross the wiping sponge, and the diameter of the wiping sponge channel opening is the same as that of the rust removal sponge channel opening; during the relative movement and approaching process of the chemical rust removal mechanism and the clamping mechanism, the threaded steel passes through the rust removal sponge at various locations and then passes through the wiping sponge to be wiped and absorb the chemical rust removal liquid remaining on the surface.
[0008] Furthermore, the rust removal shell and the rust removal sponge are both cylindrical, and the rust removal shell is provided with a detachable end cover for replacing the rust removal sponge inside.
[0009] Furthermore, the wiping part comprises a cylindrical wiping shell, and the wiping sponge is cylindrical and is installed in the wiping shell.
[0010] Furthermore, the wiping shell is provided with a detachable end cover for replacing the wiping sponge inside.
[0011] Furthermore, it includes a mobile platform, the chemical rust removal mechanism and the clamping mechanism are respectively arranged at both ends of the mobile platform, and the chemical rust removal mechanism also includes a rust removal drive device, which drives the rust removal part and the wiping part to move from one end of the mobile platform to the other end, thereby moving close to the clamping mechanism.

[0013] Furthermore, the clamping mechanism includes a first clamping member, a second clamping member, and a clamping drive device for driving the first clamping member and the second clamping member to move relatively and close to clamp the threaded steel bar.
[0014] Furthermore, the clamping drive device includes a bidirectional screw and a motor that drives the bidirectional screw to rotate.

[0015] Furthermore, the clamping parts of the first clamping member and the second clamping member are made of elastic material.
[0016] There are many different pitch specifications and many different diameter specifications of threaded steel in the industry. The utility model uses a rust removal sponge soaked in a chemical rust removal liquid to remove rust from the threaded steel. The rust removal sponge is provided with a channel for the threaded steel to pass through. The diameter of the channel is set to be slightly smaller than the diameter of the threaded steel with the smallest diameter specification in the industry. Since the sponge has very large telescopic elasticity, threaded steels of other diameter specifications can pass through the rust removal sponge from the channel and all surfaces can contact the chemical rust removal liquid on the rust removal sponge to achieve rust removal; and even if the threaded steel has different pitches and there are irregular protrusions and burrs on the surface, all surfaces of the threaded steel can contact the chemical rust removal liquid on the rust removal sponge to achieve rust removal.

[0024] The present invention is further described in detail below in conjunction with specific implementation methods.
[0025] like Figure 1 As shown, the threaded steel rust removal device includes a chemical rust removal mechanism 1. The chemical rust removal mechanism 1 includes a rust removal part 11 and a wiping part 12. The rust removal part 11 includes a rust removal shell 110 with a liquid inlet 10 on the top and a rust removal sponge 112 located in the rust removal shell 110 (see Figure 3 ). The rust removal shell 110 and the rust removal sponge 112 are both cylindrical. The rust removal sponge 112 has a channel 113 along the axis for the threaded steel bar to cross the rust removal sponge 110. The two ends of the rust removal shell 110 have openings 111 with a diameter larger than the diameter of the rust removal sponge 112 at the corresponding positions of the channel opening of the rust removal sponge 112. The operator introduces the chemical rust removal liquid from the liquid inlet 10 into the rust removal sponge 112 in the rust removal shell 110, so that the rust removal sponge 112 is soaked with the chemical rust removal liquid. Figure 1 As shown, the wiping portion 12 includes a cylindrical wiping shell 120. Figure 4 As shown, a cylindrical wiping sponge 122 is provided in the wiping housing 120. The wiping sponge 122 has a channel 123 along the axis for the threaded steel bar to cross the wiping sponge 122, and the diameter of the channel opening of the wiping sponge 122 is the same as the channel opening of the rust removal sponge 112. Openings 121 with a diameter larger than the diameter of the channel opening of the wiping sponge 122 are provided at both ends of the wiping housing 120 at positions corresponding to the channel opening of the wiping sponge 122.
[0026] The threaded steel rust removal device includes a clamping mechanism 2. The clamping mechanism 2 includes a first clamping member 21, a second clamping member 22, and a clamping drive device for driving the first clamping member 21 and the second clamping member 22 to move relatively close to clamp the threaded steel. The clamping drive device includes a bidirectional screw rod 24 and a motor 23 for driving the bidirectional screw rod 24 to rotate. The first clamping member 21 and the second clamping member 22 are respectively connected to the upper and lower ends of the bidirectional screw rod 24. The motor 23 drives the bidirectional screw rod 24 to rotate. Since the thread directions of the upper half and the lower half of the bidirectional screw rod 24 are opposite, the first clamping member 21 and the second clamping member 22 move synchronously in opposite directions, thereby synchronously moving closer or moving away.
[0027] If the above-mentioned threaded steel rust removal device is used to remove rust from the threaded steel 100, the operator first inserts the left end of the threaded steel 100 into the rust removal sponge 112 through the opening 111, and places the right end of the threaded steel 100 between the two clamping members 21 and 22 of the clamping mechanism 2 (in the initial state, the two clamping members 21 and 22 are far away from each other), and then operates the motor 23 to drive the bidirectional screw rod 24 to rotate forward, so that the first clamping member 21 and the second clamping member 22 move synchronously and approach until the right end of the threaded steel 100 is clamped. The clamping part of the first clamping member 21 and the second clamping member 22 is made of elastic material, which can produce a certain deformation, so that threaded steels of different diameters can be clamped. The threaded steel rust removal device includes a mobile platform 3, and the chemical rust removal mechanism 1 and the clamping mechanism 2 are respectively arranged at the left and right ends of the mobile platform 3. The mobile platform 3 is provided with a guide slide 31 along the length direction. The chemical rust removal mechanism 1 also includes a telescopic motor (not shown) as a rust removal drive device, which is arranged inside the mobile platform. The bottom of the rust removal part 11 and the wiping part 12 extend downward from the guide slide 31 into the interior of the mobile platform, and are connected to the telescopic rod of the telescopic motor through the same slider. The telescopic motor drives the rust removal part 11 and the wiping part 12 to move from the left end to the right end of the mobile platform 3 along the guide slide 31, and the clamping mechanism 2 is fixed, so that the rust removal part 11 and the wiping part 12 move close to the clamping mechanism 2. In this process, the threaded steel 100 is fixed, and the rust removal part 11 and the wiping part 12 move from the leftmost end of the threaded steel 100 to its rightmost end. In this way, the threaded steel 100 passes through the rust removal sponge 112 at various places to react with the chemical rust removal liquid in the rust removal sponge 112 to achieve rust removal, and then passes through the wiping sponge 122 to be wiped and absorb the chemical rust removal liquid remaining on the surface.
[0028] Not preferably, other embodiments can be changed to have the rust removal part 11 and the wiping part 12 fixed, and the telescopic motor is changed to drive the clamping mechanism 2 to move from the right end to the left end of the mobile platform, so that the clamping mechanism 2 moves close to the rust removal part 11 and the wiping part 12. During this process, the rebar 100 follows the clamping mechanism 2 and moves from right to left, so that the rebar 100 moves from the left end to the right end successively through the rust removal part 11 and the wiping part 12, that is, after the rebar 100 passes through the rust removal sponge 112 at various places to react with the chemical rust removal liquid in the rust removal sponge 112 to achieve rust removal, it immediately passes through the wiping sponge 122 to be wiped and absorbs the chemical rust removal liquid remaining on the surface.
[0029] The diameter of the channel 113 of the rust removal sponge 112 through which the threaded steel bar passes is set to be slightly smaller than the diameter of the threaded steel bar with the smallest diameter specification in the industry. Since the sponge has a very large expansion and contraction elasticity, threaded steel bars of other diameter specifications can pass through the channel through the rust removal sponge 112 and all surfaces can contact the chemical rust removal liquid on the rust removal sponge 112 to achieve rust removal; and even if the threaded steel bar has different pitches and there are irregular protrusions and burrs on the surface, all surfaces of the threaded steel bar can contact the chemical rust removal liquid on the rust removal sponge 112 to achieve rust removal. Therefore, the utility model uses the chemical rust removal liquid to achieve efficient rust removal, and can be adapted to rust removal of threaded steel bars with different pitches and different diameter specifications. After the threaded steel bar passes through the rust removing sponge 112 to achieve rust removal, chemical rust removing liquid will remain on its surface. In order to prevent the chemical reaction from excessively affecting the material of the threaded steel bar itself, the threaded steel bar passes through the rust removing sponge 112 to achieve rust removal and then enters the wiping sponge 122 for wiping. In this way, the chemical rust removing liquid remaining on the surface of the threaded steel bar can be wiped off, and the rust on the surface of the threaded steel bar can also be wiped clean, killing two birds with one stone. In particular, in this embodiment, there is a gap between the rust removal part 11 and the wiping part 12. Since the threaded steel has threads on its surface, when passing through the rust removal sponge 112, a portion of the chemical rust removal liquid at the channel of the rust removal sponge 112 will be brought out from the left end of the channel, and then flow away from the gap between the rust removal part 11 and the wiping part 12. In this way, the chemical rust removal liquid that has chemically reacted at the channel of the rust removal sponge 112 can be brought out, and the unreacted chemical rust removal liquid at other positions of the rust removal sponge 112 can flow to the channel, ensuring that the threaded steel can react with the unreacted chemical rust removal liquid when passing through the rust removal sponge 112, thereby ensuring the rust removal effect. During the rust removal process, the operator can continue to slowly add chemical rust removal liquid to the rust removal sponge 112 in the rust removal shell through the liquid inlet 10.
[0030] The rust removal shell 110 is provided with a detachable right end cap 114. After a batch of threaded steel bars are rust-removed, if the rust removal sponge needs to be replaced, the operator can remove the right end cap 114 of the rust removal shell 110, take out the rust removal sponge 112 therefrom, and then load the new rust removal sponge 112 into the rust removal shell 110, and then put the right end cap 114 back to replace the rust removal sponge. Similarly, the wiping shell 120 is provided with a detachable left end cap (not shown in the figure due to viewing angle). After working for a period of time, the wiping sponge 122 will absorb more chemical rust removal liquid. To ensure the subsequent wiping effect, the operator can remove the left end cap of the wiping shell 120, take out the wiping sponge 122 therefrom, and then load the new dry wiping sponge 122 into the wiping shell 120, and then put the left end cap back to replace the wiping sponge.
[0031] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
