Description

Technical Field

[0001] The utility model relates to the technical field of steel strip cutting, in particular to a steel strip cutting device. Background Art

[0002] At present, flying shears are often used when cutting steel strips. On existing flying shears, strip blades are used to cut steel strips. Among them, the strip blades are fixed to the lifting blade holder of the flying shear by a number of screws. Therefore, every time the strip blades are installed and removed, a lot of screws need to be fully screwed in and fully screwed out. Since the screw installation and removal process is relatively cumbersome, it is easy to affect the convenience of the strip blade installation and removal, and then it is easy to affect the installation and removal efficiency of the strip blade.

[0003] A Chinese patent with announcement number CN218575138U discloses a steel strip cutting device, which is characterized in that it includes a lifting knife holder, a positioning strip, a strip knife strip, and at least two limit screws, wherein the lifting knife holder is respectively provided with a limit notch and a clearance notch, and the two ends of the positioning strip can be rotatably embedded in the left and right walls of the limit notch, and a horizontally penetrating limit slot is provided on the bottom surface of the positioning strip, and the limit slot can enter the clearance notch as the positioning strip swings, and the limit slot is a slot structure with a small lower opening and a large interior, and an embedding strip matching the limit slot is provided on the top of the strip knife strip, and a blade portion is provided on the bottom edge of the strip knife strip, and the embedding strip is embedded in the limit slot, and each limit screw is vertically screwed on the top surface of the lifting knife holder, and the lower end of each limit screw is embedded in the top surface of the positioning strip.

[0004] Although the steel strip cutting device described in the above patent can realize the convenient disassembly and replacement of the strip blade for cutting the steel strip by twisting twice and swinging and pulling when in use, it is still inevitable to twist the limit screw when replacing the strip blade. At the same time, it is also necessary to disassemble the strip blade by pulling after the positioning bar limit is released and swung. As a result, the entire disassembly process of the strip blade for cutting the steel strip is still relatively cumbersome, which is not convenient for the efficient replacement of the strip blade for cutting the steel strip.

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.

[0031] like Figure 1-Figure 4 As shown, a steel strip cutting device in this embodiment includes a mounting seat 4, a mounting groove 7 is opened in the middle of the bottom end of the mounting seat 4, a cutting blade 5 is installed in the mounting groove 7, and two quick-release components 6 are symmetrically installed on the two side walls of the mounting seat 4 facing the mounting groove 7. The quick-release components 6 include a groove 603 opened on the side wall of the mounting seat 4, a pull plate 602 installed in the groove 603, a pull handle 601 welded to the middle of the outer wall of the pull plate 602, a limit column 605 installed on the wall of the pull plate 602 facing the groove 603, a spring 604 installed between the pull plate 602 and the groove 603, and a limit column 605 opened on the cutting blade 5 facing the limit column 605. Slot 606, after the limit slot 606 and the limit column 605 are inserted into each other, the cutting blade 5 can be reliably limited and fixed in the mounting slot 7. The spring 604 is mainly used to realize the automatic resetting of the pull plate 602 after the external force is removed. During the replacement of the cutting blade 5, the bottom of the cutting blade 5 needs to be in contact with the cutting table. This design can enable the cutting blade 5 to be automatically separated from the mounting sleeve under the action of its own weight as the mounting sleeve moves upward after the limit is released. There is no need for manual sliding disassembly operation. At the same time, this disassembly method also saves the tedious operation of twisting and disassembly, which is convenient for the quick replacement of the cutting blade 5 during the steel strip cutting process.

[0032] like Figure 1-Figure 4 As shown, in this embodiment, a connecting plate 2 is also welded to the top of the mounting seat 4, and two guide ear plates 3 are symmetrically installed on the two side walls of the connecting plate 2. The guide ear plates 3 are mainly coordinated with the guide columns installed on the steel strip flying shear to ensure that the cutting plate 5 moves downward smoothly when cutting the steel strip. A hydraulic rod 1 is also fixed to the middle part of the upper end of the connecting plate 2 for convenient lifting of the cutting plate 5. The hydraulic rod 1 can realize the repeated lifting of the cutting plate 5 to facilitate the cutting operation of the steel strip.

[0033] like Figure 1-Figure 4As shown, in this embodiment, the cutting blade 5 is slidably connected to the mounting groove 7, the limiting groove 606 is formed on the cutting blade 5, and the limiting groove 606 does not penetrate the cutting blade 5, the limiting column 605 penetrates the side wall of the mounting seat 4 and is slidably connected to the side wall of the mounting seat 4, the size of the limiting column 605 matches the size of the limiting groove 606, which can ensure the smooth sliding of the limiting column 605 relative to the side wall of the mounting seat 4, the limiting column 605 penetrates the spring 604, one end of the spring 604 is welded to the pull plate 602, and the other end of the spring 604 is welded to the groove 603, the pull plate 602 is welded to the limiting column 605, the limiting column 605 is evenly spaced and parallelly distributed on the pull plate 602, and the pull handle 601 can be used to achieve convenient pulling and pulling operation of the pull plate 602.

[0034] The specific implementation process of this embodiment is as follows: when the cutting blade 5 is replaced during the steel strip cutting process, first, the bottom of the cutting blade 5 is brought into contact with the cutting table, and then the limiting column 605 is pulled out of the limiting groove 606 by means of the pull plate 602, and then the mounting seat 4 is driven upward by the hydraulic rod 1, and the cutting blade 5 can be made to slide out of the mounting groove 7 by the self-weight of the cutting blade 5 while the mounting seat 4 is moved upward. When the new cutting blade 5 is directly below the mounting seat 4, it is only necessary to pull the limiting column 605 out of the limiting groove 606 by means of the pull plate 602, and then the mounting seat 4 is driven upward by the hydraulic rod 1, and the self-weight of the cutting blade 5 can be used to make the cutting blade 5 slide out of the mounting groove 7. When the new cutting blade 5 is directly below the mounting seat 4, it is only necessary to pull the limiting column 605 out of the limiting groove 606 by means of the pull plate 602. The mounting groove 7 on the mounting seat 4 is reinserted into the upper part of the new cutting blade 5 and the pull plate 602 is released, so that the limiting column 605 can be reinserted into the limiting groove 606 on the new cutting blade 5 during the resetting process of the spring 604, so as to realize the rapid limitation of the new cutting blade 5. In the above-mentioned replacement method, it is quickly removed from the mounting groove 7 by sliding and pulling, which completely eliminates the screwing and pulling operations of the cutting blade 5 during disassembly, and facilitates the rapid replacement of the cutting blade 5 during the steel strip cutting process.
