Description

Technical Field

[0001] This utility model relates to the field of cutting and leveling technology, and in particular to a steel plate cutting device. Background Technology

[0002] In the production of fiberglass, to improve its strength and durability, a layer of metal material, such as tinplate, is often laminated onto the fiberglass. Before lamination, the tinplate roll must be leveled and then precisely cut to ensure its size and shape match the fiberglass. However, during the cutting of tinplate, because tinplate is usually quite wide, a long cutting blade is required. This leads to insufficient stability of the cutting blade in traditional cutting devices with only one hydraulic cylinder. When using two hydraulic cylinders, the asynchronous extension and retraction speeds of the two cylinders result in inconsistent descent speeds on both sides of the cutting blade, further affecting the cutting accuracy. In addition, tinplate, as a soft plastic material, is prone to significant vibration during cutting, and may even bend or shift. These factors all negatively impact the cutting quality. Therefore, to improve the cutting accuracy and quality of tinplate, a more stable and precise cutting device is needed. Utility Model Content

[0010] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0011] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0012] according to Figures 1-2As shown, a steel plate cutting device includes a frame 1, which is configured as a portal frame. Support bases 2 are located at the bottom of both ends of the frame 1. A pair of lifting cylinders 3 are symmetrically arranged on the top of the frame 1. The movable ends of the lifting cylinders 3 pass through the top of the frame 1 and a cutter holder 4 is installed inside the frame 1. The lifting cylinders 3 control the lifting and lowering of the cutter holder 4, allowing the cutting blade 41 to cut. Lifting guide rails 5 are provided on the frame 1 at both ends of the cutter holder 4 to cooperate with the cutter holder 4. A feed table 6 is also provided at the bottom of the frame 1 behind the cutter holder 4, through which the tinplate to be cut passes. The bottom of the cutter holder 4 is equipped with a cutting blade 41, which is inclined. The inclined cutting blade 41 facilitates cutting. Symmetrical supports 2 are located on both sides of the front end of the cutter holder 4. The machine has a rack 12, and bearing seats 8 are provided on both sides of the front end of the frame 1. A rotating shaft 10 is provided at the front end of the frame 1 through the bearing seats 8. A pair of gears 11 are provided on the rotating shaft 10. The position of the gears 11 corresponds to the position of the rack 12. The teeth of the gears 11 and the rack 12 mesh with each other. The lifting guide rail 5 allows the cutter frame 4 to be raised and lowered stably. With the gears 11 and the rack 12, the two ends of the cutter frame 4 can be raised and lowered synchronously. Several spring seats 9 are arranged on the rear side of the cutter frame 4. An elastic pressure plate 13 is provided at the bottom of the spring seat 9. The elastic pressure plate 13 is located above the feed table 6. During the descent of the cutter frame 4, the elastic pressure plate 13 will follow and descend. The elastic pressure plate 13 and the feed table 6 can hold the tinplate and ensure that the cutting blade 41 at the front end can make precise cuts.

[0013] The spring seat 9 includes a mounting block 91, which is fixedly mounted on the rear side of the cutter holder 4. An adjusting screw 92 is vertically mounted on the mounting block 91, and a nut sleeve 93 is also mounted on the adjusting screw 92. The nut sleeve 93 is located on the upper end of the mounting block 91. The elastic pressure plate 13 is fixedly connected to the lower end of the adjusting screw 92. A pressure spring 94 is mounted on the adjusting screw 92 and is located between the elastic pressure plate 13 and the mounting block 91. The frame 1 at both ends of the elastic pressure plate 13 is provided with a second guide rail 95 that cooperates with the elastic pressure plate 13. The second guide rail 95 is used to ensure the stable lifting and lowering of the elastic pressure plate 13. The nut sleeve 93 is located on the upper end of the mounting block 91 to prevent the adjusting screw 92 from coming off. At the same time, by rotating the nut sleeve 93, the position of the nut sleeve 93 on the adjusting screw 92 can be changed, and the initial height position of the elastic pressure plate 13 can be adjusted.

[0014] The support base 2 is provided with multiple support screws 21, and the four corners of the bottom of the frame 1 are provided with connecting ears 14. The support screws 21 are passed through the connecting ears 14. A pair of adjusting nuts 22 are also provided on the support screws 21. The adjusting nuts 22 are located on the upper and lower sides of the connecting ears 14.

[0015] During use, the tinplate is conveyed by the rear conveyor, then passes through the feed table 6, and moves to the position where it needs to be cut before stopping. Then, the lifting cylinder 3 is activated, controlling the cutting blade 41 to move downward, forming a scissor structure with the front end of the feed table 6 to cut the tinplate. During the cutting process, the elastic pressure plate 13 presses down on the tinplate on the feed table 6 as the cutting blade holder 4 descends, preventing the tinplate from vibrating or bending during the cutting process, thus ensuring the cutting quality. When the cutting blade holder 4 is raised and lowered, the rack 12 also rises and falls accordingly. Through the cooperation of the rack 12 and the gear 11, the synchronicity of the two ends of the cutting blade holder 4 during the raising and lowering process can be ensured.

[0016] This design is ingenious. By cooperating with the lifting guide rail 5 and the rack 12 and gear 11, the cutting blade 41 can move precisely during cutting, thereby improving the cutting accuracy of tinplate. The elastic pressure plate 13 can keep the tinplate stable during cutting, preventing vibration, bending or displacement during the cutting process, and ensuring the consistency and reliability of the cutting quality.

[0017] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
