Description

Technical Field

[0001] The invention relates to a hot-rolled steel coil rust removal production device. Background Art

[0002] Hot-rolled steel coil is a steel product processed by hot rolling process and is widely used in construction, manufacturing, automobile industry and other fields. Hot rolling refers to heating the steel billet to an appropriate temperature and then rolling it through a roller to form the required steel coil. After the steel coil is left for a long time, it may oxidize and rust. It is necessary to use a hot-rolled steel coil rust removal production device for rust removal. The device is used to remove the oxide layer, rust and dirt on the surface of the hot-rolled steel coil. Rust removal is to protect the surface of the steel coil, improve its adhesion and surface quality, and provide a good foundation for subsequent processing or coating. In the process of derusting the steel coil, it is necessary to support and fix the steel coil on the device from the inside of the steel coil, and rotate the device to unfold the steel coil for derusting. Due to the different sizes of the steel coils, the inner diameters of the steel coils are also different. When the support device needs to be adjusted according to the different inner diameters of the steel coils, the process is cumbersome, which reduces work efficiency. In addition, some rust removal devices use chemical rust removal liquid for rust removal. A filter will be set inside the device to separate the rust removal liquid and rust residue, which is convenient for operators to classify and clean. However, the filter will become clogged after being used for a long time, and it needs to be disassembled by rotating the bolts multiple times to clean the filter, which is time-consuming and labor-intensive.

Implementation

[0008] See also Figure 1-Figure 5 A hot-rolled steel coil rust removal production device includes a base 1, which can be fixed to the ground by bolts, etc. to prevent the device from vibrating and tipping over during operation, affecting the rust removal effect. The left outer wall of the base 1 is fixedly connected to a fixed platform 2, and the top outer wall of the fixed platform 2 is fixedly connected to a stopper 3, which can be driven by a motor to rotate the stopper 3 and drive the steel coil to rotate, so that the steel coil is unfolded and transported to a shell 9 for rust removal. The outer wall of the stopper 3 is provided with multiple groups of through grooves 8, which can guide the splint 7 so that the splint 7 maintains linear motion when moving. The outer wall of the stopper 3 is slidably connected to a pull rod 4, which passes through one side outer wall of the stopper 3. The operator can hold and pull the pull rod 4 to drive the splint 7 to move to a suitable position to support and fix the steel coil.

[0009] The top outer wall of the pull rod 4 is provided with multiple groups of limit grooves 5. The setting of the multiple groups of limit grooves 5 allows the pull rod 4 to drive the splint 7 to be fixed at multiple positions to accommodate steel coils with different inner diameters. The outer wall of the pull rod 4 is hinged with the splint 7 through the connecting rod 6. A protrusion is provided on the outer wall of one end of the splint 7 to fix the steel coil and prevent it from falling off. One end of the connecting rod 6 is hinged to the outer wall of the splint 7, and the other end of the connecting rod 6 is hinged to the outer wall of the pull rod 4. When the pull rod 4 is pulled, the pull rod 4 drives the connecting rod 6 to flip and drives the splint 7 to move. The outer wall of the splint 7 is slidably connected to the inner wall of the through groove 8. When the splint 7 moves, due to the guiding effect of the through groove 8, the splint 7 maintains horizontal or vertical linear motion and expands outward or contracts inward at the same time.

[0010] The outer wall of the stopper 3 is fixedly connected with a card block A12, and the top inner wall of the card block A12 is elastically connected with a wedge block A14 through a spring A13. The outer wall of the wedge block A14 is provided with a protrusion, and the protrusion passes through the outer wall of one side of the card block A12 and slides on the outer wall of the card block A12. When the protrusion is moved upward, the wedge block A14 can be driven to move upward at the same time. One end of the spring A13 is fixedly connected to the top inner wall of the card block A12, and the other end of the spring A13 is fixedly connected to the top outer wall of the wedge block A14. When it is necessary to pull the pull rod 4 outward, the protrusion can be moved upward to move the wedge block A14 upward, and the limit of the pull rod 4 can be released.

[0011] The outer wall of the wedge block A14 is slidably connected to the inner wall of the clamping block A12, and the wedge block A14 is clamped in the limiting groove 5. In the absence of external force, the spring A13 drives the wedge block A14 to pop out downward due to its own elastic force, and the straight surface of the wedge block A14 contacts the inner wall of the limiting groove 5, which can limit the pull rod 4 and fix the position of the pull rod 4, thereby conveniently and quickly adjusting the position of the splint 7 according to the inner diameter of the steel coil.

[0012] The right outer wall of the base 1 is fixedly connected with a shell 9, which is the main body of the rust removal device. The chemical rust removal liquid can be transported to the interior of the shell 9 through a delivery pipe arranged on the outer wall of the top end of the shell 9, and the steel coil inside the shell 9 is rusted. A slide groove 10 is provided on the inner wall of the shell 9, and a filter screen 11 is slidably connected to the inner wall of the slide groove 10. The filter screen 11 can separate the rust residue from the rust removal liquid, which is convenient for operators to carry out classification processing. A clamping block B15 is fixedly connected to the outer wall of the clamping block B15, and a wedge block B17 is elastically connected to the inner wall of the bottom end of the clamping block B15 through a spring B16. When the filter screen 11 is installed in the interior of the shell 9, the wedge block B17 pops up due to the elastic force of the spring B16 itself, and the straight surface of the wedge block B17 contacts the outer wall of the filter screen 11, thereby limiting the filter screen 11 and fixing the filter screen 11 in the interior of the shell 9.

[0013] One end of the spring B16 is fixedly connected to the inner wall of the bottom end of the block B15, and the other end of the spring B16 is fixedly connected to the outer wall of the bottom end of the wedge block B17. When the filter 11 needs to be removed, the wedge block B17 can be pressed downward to release the limit of the filter 11 and take out the filter 11. The outer wall of the wedge block B17 is slidably connected to the inner wall of the block B15. The filter 11 can be disassembled and installed conveniently and quickly through the wedge block B17 without the need to rotate the bolts multiple times, saving time and effort.

[0014] When in use, the operator can first adjust the position of the clamping plate 7 according to the inner diameter of the steel coil to be derusted to support and fix the steel coil. When the clamping plate 7 needs to be adjusted outward, the pull rod 4 can be moved inward to make the arc surface of the wedge block A14 contact the inner wall of the limiting groove 5. The wedge block A14 is forced to move inward along the inner wall of the clamping block A12. When the pull rod 4 moves, it can drive the connecting rod 6 to flip and drive the clamping plate 7 to move. Through the guiding effect of the through groove 8, the clamping plate 7 maintains an outward linear motion. When the outer wall of the clamping plate 7 is completely in contact with the inner wall of the steel coil, the wedge block A14 pops up downward due to the elastic force of the spring A13 itself, and is clamped with the limiting groove 5. The straight surface of the wedge block A14 contacts the inner wall of the limiting groove 5, fixes the position of the pull rod 4, fixes the position of the clamping plate 7, and fixes the two sides of the steel coil through the stop block 3 and the protrusions set on the outer wall of the clamping plate 7, thereby supporting and fixing the steel coil to prevent the steel coil from falling off when rotating and affecting the rust removal effect.

[0015] When it is necessary to adjust the splint 7 inward, the protrusion set on the outer wall of the wedge block A14 can be moved upward, and the wedge block A14 can be driven to move upward. The spring A13 is forced to contract, so that the wedge block A14 is out of contact with the inner wall of the limiting groove 5, and the limit on the pull rod 4 can be released. Then the pull rod 4 is pulled outward to flip the connecting rod 6, and the splint 7 is driven to move linearly inward at the same time through the guiding effect of the through groove 8. When the splint 7 is adjusted to a suitable position and the outer walls of the splint 7 are completely in contact with the inner wall of the steel coil, the wedge block A14 pops up downward and engages with the limiting groove 5, fixing the position of the pull rod 4 and the splint 7, so that the position of the splint 7 can be conveniently and quickly adjusted according to the different inner diameters of the steel coil, thereby improving work efficiency.

[0016] When the steel coil is derusted on the inner wall of the shell 9, a large amount of rust residue will remain on the surface of the filter screen 11. At this time, the operator can press the wedge block B17 downward to make the wedge block B17 move downward along the inner wall of the card block B15 and break away from the outer wall of the filter screen 11, so as to release the limit of the filter screen 11 and take out the filter screen 11 for cleaning. When the filter screen 11 is cleaned and needs to be installed, the filter screen 11 can be aligned with the position of the slide groove 10, and the filter screen 11 can be inserted inward. The outer wall of the filter screen 11 contacts the arc surface of the wedge block B17, and the wedge block B17 moves inward under the extrusion force. When the filter screen 11 is installed, the wedge block B17 pops up upward due to the elastic force of the spring B16 itself, and the straight surface of the wedge block B17 contacts the outer wall of the filter screen 11, limiting the filter screen 11 and fixing the filter screen 11 inside the shell 9. It can be disassembled and installed without rotating the bolts multiple times, which is more time-saving and labor-saving.
