Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing equipment, in particular to a rust removal device used for bolt pre-processing. Background Art

[0002] During industrial production and maintenance, bolts are usually exposed to harsh environments, such as humidity, high temperature, chemical corrosion, etc., which can easily cause rust. Rust will reduce the strength and durability of the bolts, thereby affecting their tightening effect and safety. Therefore, it is necessary to pre-treat the bolts with a rust removal device. The rust removal device is used to remove rust on the surface of the bolts to ensure that the bolts have good performance and reliability when in use. In the prior art, rust-containing bolts are often derusted by soaking them in a rust removal solution;

[0003] The existing rust removal devices generally have technical defects when working, that is, during the rust removal process, the rust residue attached to the outer surface of the bolt will fall into the inside of the storage net frame. Although most of the rust residue will directly fall out of the holes of the storage net frame, some of the rust residue will still remain in the storage net frame or on the bolt. This results in that when the bolt is taken out from the storage net frame, it is necessary to manually clean the rust residue left on the surface of the bolt and the rust residue left inside the storage net frame, which seriously reduces the rust removal efficiency of the bolt. In this regard, the utility model provides a rust removal device for bolt pre-processing to solve the above technical problems. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1-Figure 2 As shown, a rust removal device for bolt pre-processing provided by an embodiment of the utility model comprises a rust removal tank 1, wherein an appropriate amount of rust removal solution is stored inside the rust removal tank 1. After the bolt is immersed in the rust removal solution in the rust removal tank 1, the rust removal solution can fully clean the rust on the surface of the rust removal tank 1, and during the rust removal process, some rust residue will fall off from the outer surface of the bolt;

[0021] A support frame 4 is connected to the side of the rust removal pool 1, and an electric telescopic rod 3 is installed on the outer side of the support frame 4, one end of the electric telescopic rod 3 is connected to an L-shaped support plate 11, and the surface of the L-shaped support plate 11 is slidably connected to a storage net frame 5, preferably, the number of the electric telescopic rod 3 and the L-shaped support plate 11 is two, and the two electric telescopic rods 3 and the L-shaped support plate 11 are symmetrically arranged with the storage net frame 5 as the center reference object;

[0022] The storage net frame 5 is used to hold the bolts. Before the bolts are immersed in the rust removal solution for rust removal, multiple bolts should be neatly and orderly stacked inside the storage net frame 5, and a gap of at least 2 cm should be left between adjacent bolts;

[0023] A guide rail 12 is provided on the surface of the L-shaped support plate 11, a guide slider 13 is installed on the outer side of the storage net frame 5, and the storage net frame 5 is slidably connected to the surface of the L-shaped support plate 11 through the cooperation of the guide slider 13 and the guide rail 12, a spring 14 is installed on the side of the storage net frame 5, a through hole 15 is opened on the surface of the L-shaped support plate 11, and a guide rod 16 is connected to the side of the storage net frame 5, and the guide rod 16 is sequentially arranged through the spring 14 and the through hole 15;

[0024] A mounting seat 7 is connected to the side of the rust removal tank 1 , and a pneumatic push rod 6 is installed on the surface of the mounting seat 7 , and an impact block 17 is provided at one end of the pneumatic push rod 6 .

[0025] In one embodiment of the utility model, when the bolts are derusted, a plurality of bolts are first neatly stacked inside the storage net frame 5, and then the two electric telescopic rods 3 are opened, and the two electric telescopic rods 3 jointly drive the L-shaped support plate 11 and the storage net frame 5 to move downward until the plurality of bolts inside the storage net frame 5 are completely immersed in the derusting solution inside the derusting tank 1, and then the storage net frame 5 and the bolts are left stationary inside the derusting tank 1 for a period of time, so that the rust on the outer surface of the bolts fully reacts with the derusting solution until the rust on the outer surface of the bolts is fully cleaned. It can be understood that during the derusting process, the rust residue attached to the outer surface of the bolt will fall into the storage net frame 5, but although most of the rust residue will fall directly from the holes of the storage net frame 5, some rust residue will still remain in the storage net frame 5 or on the bolts;

[0026] After the rust on the outer surface of the bolt is fully removed, the two electric telescopic rods 3 are opened again, and the L-shaped support plate 11 and the storage net frame 5 are restored to their original positions. It should be noted that at this time, the impact block 17 corresponds to the side of the storage net frame 5, and there is no shielding between the impact block 17 and the storage net frame 5. Then, the pneumatic push rod 6 is opened. After the pneumatic push rod 6 is energized, it will drive the impact block 17 to move quickly and move toward the storage net frame 5, so that the impact block 17 impacts the storage net frame 5 and causes the storage net frame 5 to vibrate, thereby causing the remaining Part of the rust residue inside the storage net frame 5 or on the bolts can be vibrated and fall into the holes of the storage net frame 5, so that after the storage net frame 5 and the bolts inside the storage net frame 5 are fished out from the rust removal solution, part of the rust residue left in the storage net frame 5 can be fully cleaned off. Therefore, when the bolts are taken out from the storage net frame 5, there is no need to manually clean the rust residue left on the surface of the bolts and the rust residue left inside the storage net frame 5, which not only improves the cleanliness of the bolts after rust removal, but also improves the rust removal efficiency of the rust removal device for bolt pre-processing.

[0027] Preferably, an inclined plate 2 is provided at the inner bottom of the rust removal pool 1, so that the rust residue dropped from the storage net frame 5 can be collected on one side of the inner bottom of the rust removal pool 1 under the guidance of the inclined plate 2, so that the staff can clean up this part of the rust residue.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment of the utility model, a collecting bucket 8 is detachably connected to the side of the rust removal pool 1, and a filter mesh plate 9 is installed inside the collecting bucket 8, a drain pipe 10 is arranged on the outside of the collecting bucket 8, and a control valve is installed on the outside of the drain pipe 10;

[0029] A connecting threaded hole is provided on the side of the rust removal pool 1 near the collecting bucket 8 , and a connecting thread is provided on the outer side of the collecting bucket 8 . The collecting bucket 8 is detachably connected to the rust removal pool 1 through the connecting threaded hole and the connecting thread.

[0030] In this embodiment, the inclined surface of the inclined plate 2 corresponds to the direction of the collecting bucket 8, and the rust residue guided by the inclined plate 2 will enter and be collected in the collecting bucket 8;

[0031] When the rust removing solution in the rust removing tank 1 is discharged, the valve on the drain pipe 10 can be directly opened, so that the rust removing solution in the rust removing tank 1 will be discharged through the collecting bucket 8 and the drain pipe 10, and when the rust removing solution passes through the collecting bucket 8, the rust residue contained in the rust removing solution will be intercepted by the filter mesh plate 9 arranged inside the collecting bucket 8, so that the rust residue in the rust removing solution can be fully collected inside the collecting bucket 8, and by providing a connecting threaded hole on the rust removing tank 1 and a connecting thread on the outer side of the collecting bucket 8, it is convenient for the staff to remove the collecting bucket 8 from the side of the rust removing tank 1, so that it is convenient for the staff to clean up the rust residue collected inside the collecting bucket 8.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
