Description

Technical Field

[0001] The utility model relates to the technical field of channel steel processing, in particular to a channel steel rolling structure. Background Art

[0002] Channel steel is a long steel strip with a grooved cross-section. Its rolling process is to compress and extend the steel billet or ingot in the length direction through specific processes and equipment to obtain channel steel products with the required cross-sectional shape, dimensional accuracy and surface quality.

[0003] Reference can be made to the existing literature for a channel steel rolling structure (CN220560137U). The reference literature uses the first driving mechanism to push the upper die downward, which can press the steel plate into the forming groove. By utilizing the structural coordination of the forming groove and the upper die, the steel plate can be rolled into a U-shaped structure to make channel steel. The overall structure is simple and easy to process, which is conducive to miniaturized layout. Compared with traditional rolling mill equipment, the cost investment is small and it is more suitable for the production needs of civil defense door manufacturers.

[0004] In the process of rolling the steel billet into a concave shape, a pressing plate needs to be pressed into the steel billet to form a groove. When the pressing plate is continuously pressed into the interior of the steel billet, it will contact and rub against the steel billet, causing the pressing plate to wear more during use. For example, the one-piece telescopic structure and pressing plate designed in the above-mentioned document are inconvenient to replace the pressing plate, and the fixed-length pressing plate has a limited scope of application and is not applicable to steel billets of larger lengths.

The present invention extends the pressing plate, and the extended pressing plate can be connected to both ends of the pressing plate by a splicing plate. The extended pressing plates can be continuously spliced ​​horizontally by the design of the splicing plate and the second clamping slot, thereby extending the length of the pressing plate so that it can be assembled according to the length of the steel billet. At the same time, the connecting seat, the pressing plate and the extended pressing plate can be connected by screws, so that the pressing plate can be independently disassembled and replaced, which is convenient for quickly replacing the worn pressing plate.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The extension pressing plate 9 is the same height as the pressing plate 8. After the extension pressing plate 9 and the pressing plate 8 are spliced, the whole can be rolled downward. The splicing plate 15 at one end of the extension pressing plate 9 can be just inserted into the card slot 10. The depth is half of the slot 10. When the two sets of splicing plates 15 are fully inserted into the slot 10, the extended pressure plate 9 is fitted with the end of the pressure plate 8 to complete the docking. The connecting seat 7 is connected to the telescopic part of the No. 1 electric cylinder 6. The connecting seat 7, the pressure plate 8 and the splicing plate 15 are all connected by screws 12, so that the pressure plate 8 can be partially removed from the connecting seat 7, and the slot 2 16 opened at the other end of the extended pressure plate 9 can be docked with the splicing plate 15, so that the extended pressure plates 9 can be docked with each other to continue to extend the length.

[0027] Specifically, two screw holes 11 are provided on the upper end of the pressure plate 8, and screw holes 17 17 that match the screw holes 11 are provided on the splicing plate 15. When the splicing plate 15 is fully inserted into the slot 10, the screw holes 11 and the screw holes 17 are aligned. The screw rod 12 is connected from the upper end of the connecting seat 7. The connecting seat 7 also has screw holes that match the screw holes 11 and the screw holes 17. Two screw rods 12 are connected from the upper end of the connecting seat 7. The screw rods 12 are connected to the screw holes 17 and the screw holes 11 in turn, so that the connecting seat 7, the pressure plate 8 and the splicing plate 15 are fixed, and then the fixing of the connecting seat 7, the pressure plate 8 and the extended pressure plate 9 is completed, and the screw rod 12 is locked by the nut 13 at the end face close to the connecting seat 7.

[0028] Furthermore, a second screw hole 17 is provided at the upper end of the extended pressure plate 9. The extended pressure plates 9 can be spliced ​​to each other by inserting the splicing plate 15 into the second slot 16. After the extended pressure plates 9 are docked with each other, the splicing plate 15 at one end of the extended pressure plate 9 is inserted into the second slot 16 of the other extended pressure plate 9 to complete the docking. At this time, the second screw hole 17 of the splicing plate 15 is aligned with the second screw hole 17 on the extended pressure plate 9, and the screw 12 and nut 13 can be connected and fixed according to the above operation.

[0029] In this embodiment, it includes: a base 1 and a top plate 3, the base 1 and the top plate 3 are connected by four support rods 2, the steel billet 5 is placed on the base 1, the top plate 3 is connected to the driving assembly and the rolling assembly, and the four support rods 2 fix the base 1 and the top plate 3.

[0030] Furthermore, electric cylinder No. 1 is fixedly installed on the upper end of the top plate 3, and the telescopic part of electric cylinder No. 1 passes through the top plate 3 and is connected to the upper end of the connecting seat 7. Electric cylinder No. 1 is fixed to the upper end of the top plate 3 by bolts. The operation of electric cylinder No. 1 drives the connecting seat 7 to move through the telescopic part, and then drives the calendering assembly fixed to the connecting seat 7 to move.

[0031] Furthermore, a scale plate 14 is embedded in the middle of the front end of the pressing plate 8, and the zero scale of the scale plate 14 is located at the bottom. When the pressing plate 8 is pressed into the inside of the steel billet 5, the depth of the pressing can be known by observing the scale part exposed by the scale plate 14, which is convenient for adjustment according to needs.

[0032] Specifically, such as Figure 4 As shown, the base 1 is symmetrically equipped with two clamping assemblies, which clamp and fix the two ends of the middle billet 5. The clamping assemblies are installed on the base 1 through the fixing seat 4. A No. 2 electric cylinder 18 is provided in the clamping assembly and is fixed to one end of the fixing seat 4. The telescopic part of the No. 2 electric cylinder 18 is connected to the limiting plate 19, and the rubber pad 20 is connected to the limiting plate 19. The No. 2 electric cylinder 18 is fixed to one end of the fixing seat 4 by bolts. The two No. 2 electric cylinders 18 run synchronously to drive the limiting plate 19 to move closer to the middle, clamping and fixing the two ends of the billet 5, effectively preventing the position of the billet 5 from shifting during the rolling process. The rubber pad 20 on the surface of the limiting plate 19 can reduce the hard wear on the billet 5.
