Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a bending machine for producing galvanized steel sheets. Background Technology

[0002] Galvanized steel sheet is a metallic material with a zinc layer covering the surface of steel sheet. The galvanizing process greatly improves the corrosion resistance and service life of the steel sheet. The interior of the galvanized steel sheet is an iron substrate, and the outer zinc layer plays a key role in protecting the internal iron material from corrosion. This material is widely used in many fields such as construction, home appliances, automobiles, ships and containers manufacturing, and electromechanical industries. Early bending processes mostly relied on manual operation and simple mechanical tools. Operators relied on experience and manual skills to bend the galvanized steel sheet. However, with the advancement of technology, electric drive technology has been gradually applied to bending machines, making the bending machine's power output more powerful and the operation relatively simple. It allows galvanized steel sheets to be bent at various angles to meet the needs of different scenarios. In order to better bend galvanized steel sheets, a bending machine for galvanized steel sheet production is needed.

[0003] The technological focus of galvanized steel sheet bending machines is on improving fixing efficiency, reducing reliance on manual labor, optimizing precision control, and enhancing surface protection. While these machines have introduced some mechanical transmission and control methods, representing an improvement over purely manual operation, limitations remain. The adjustment of bending angles is often imprecise, relying on relatively coarse dials and manual knobs, which cannot adapt to complex and ever-changing product design requirements. Furthermore, friction between the cutting tool and the steel sheet during bending reduces tool accuracy and significantly shortens tool life. Suitable cutting tools can better interact with the steel sheet during processing, reducing the tool's reaction force and wear on the equipment. Regularly replacing cutting tools to avoid excessive wear and increased equipment load helps extend the service life of the bending machine's mechanical components and hydraulic system. However, traditional bending machines still require significant manual labor for tool replacement, and manual angle adjustment is necessary when folding different thicknesses, resulting in numerous steps, consuming considerable manpower and time, and impacting the efficiency of bending galvanized steel sheets.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 2 - Appendix Figure 4This utility model provides an embodiment of a bending machine for producing galvanized steel sheets, including a frame 1. A sliding buckle 3 is slidably connected to the top left side of the inner wall of the frame 1. Sliding blocks 4 are slidably connected between adjacent sliding buckles 3. Clamping plates 5 are provided on the front and rear sides of the sliding blocks 4 to fix the cutting tool 16. A threaded rod 6 is threadedly connected to the inner wall of the clamping plate 5. Nuts 7 are threadedly connected to the front and rear sides of the outer wall of the threaded rod 6. When the cutting tool 16 needs to be replaced, it is rotated to loosen the cutting tool 16. A fixing block 8 is fixedly connected to the bottom of the sliding buckle 3. A supporting cylinder 23 is fixedly connected to the top of the fixing block 8. A spring 9 is provided on the outer wall of the supporting cylinder 23. Circular holes 22 are provided on the left and right sides of the top of the sliding block 4. Springs 9 are located on the inner walls of the two fixing blocks 8. When the hydraulic rod 25 descends, the sliding block 4 can move downwards, passing through the circular holes 22 and the supporting cylinder 23, thus pressing the spring 9 downwards. The spring 9 then rebounds back to its original position. Motor 12 is fixedly connected to both the left and right rear sides of the interior of frame 1. Gear 11 is fixedly connected to the output end of motor 12. A slide rail rack 10 is meshed with the outer wall of gear 11. After motor 12 is started, the sliding buckle 3 slides on the slide rail rack 10. Support block 2 14 is fixedly connected to the front side of sliding block 4. Motor 2 15 is fixedly connected to the rear side of support block 2 14. Threaded rod 2 6 is connected to the output end of motor 2 15. A screw thread is threaded near the edge of the rear end of threaded rod 2 6. Nut 27 is fixed to the rear side of the nut near the edge and connected to a support cylinder 17. The rear end of the support cylinder 17 is fixedly connected to a connecting plate 18. The motor 15 is started to rotate, thereby rotating the connecting plate 18 and loosening the clamping plate 5. The tool 16 is movably connected to the rear side of the clamping plate 5. An adjustment mechanism 2 is provided on the inner bottom of the frame 1. The adjustment mechanism 2 is used for multi-angle adjustment to adapt to different directions. The front side of the slide rail rack 10 is fixedly connected to the rear side of the slide buckle 3.

[0033] Specifically, when changing the tool 16, start the motor 12. At this time, the gear 11 connected to the output end of the motor drives the slide rail rack 10 to slide. The sliding buckle 3 connected to the slide rail rack 10 moves with the rack. After reaching the designated position, start the motor 25 to make the nuts 27 on all the threaded rods rotate, thereby loosening the clamping plate 5 and causing the tool 16 to fall off.

[0034] Please see the appendix Figure 1 - Appendix Figure 2The adjustment mechanism 2 includes a base 201, the bottom of which is fixedly connected to the top inner side of the frame 1. A base groove 202 is formed on the top of the base 201, and a slider 203 is slidably connected to the inner wall of the base groove 202. The base groove 202 allows the slider 203 to move on the base 201. A threaded rod 204 is threadedly connected to the middle of the slider 203, and a rotary switch 205 is threadedly connected to the outer wall of the threaded rod 204. A multi-angle abrasive 206 is movably connected to the bottom inner wall of the frame 1. When it is necessary to fix the multi-angle abrasive 206, the rotary switch 205 can be rotated for fixation. The inner wall of the multi-angle abrasive 206 is fixed. A fixed column 207 is connected to the frame 1. Motors 212 are fixedly connected to the left and right ends of the bottom inner side of the frame 1. A disc 211 is fixedly connected to the output end of motor 212. When motor 212 starts, it drives the disc 211 to rotate. A positioning block 210 is fixedly connected to the left side of the disc 211 near the edge. A rotating shaft 209 is rotatably connected to the positioning block 210. A connecting block 208 is rotatably connected to the outer wall of the rotating shaft 209. The front side of the connecting block 208 is fixedly connected to the rear side of the fixed column 207. When the disc 211 rotates, it moves through the positioning block 210 and the rotating shaft 209, thereby causing the connecting block 208 and the fixed column 207 connected to it to rise, thereby adjusting the angle.

[0035] Specifically, when angle adjustment is required, first release the rotary switch 205 that fixes the multi-angle mold 206, then start the motor 212. At this time, the disc 211 will rotate with the motor, thereby driving the positioning block 210, the rotating shaft 209, and the connecting block 208 to rotate together. The fixed column 207 is fixedly connected to the connecting block 208, so the multi-angle mold 206 begins to rise, and the angle can be adjusted at this time.

[0036] Please see the appendix Figure 5 - Appendix Figure 6 A limiting block 19 is fixedly connected to the upper part of the outer wall of the frame 1, and a fixing block 20 is fixedly connected to the bottom of the inner wall of the frame 1. The limiting block 19 prevents the sliding buckle 3 from derailing, while the fixing block 20 further secures it. A base 24 is fixedly connected to the rear bottom of the frame 1. A rotating cylinder 21 is rotatably connected to the outer wall of the base 24. When the tool 16 is changed, the tool 16 falls to the base 24 and then slides down through the rotating cylinder 21.

[0037] Specifically, when changing the tool 16, the limit block 19 can effectively prevent the slip 3 from derailing. After the tool 16 falls off, it can be effectively removed by rotating cylinder 21.

[0038] Please see the appendix Figure 2 - Appendix Figure 4The left side of the motor 12 is fixedly connected to the support block 13. The left and right sides of the slide rail rack 10 are fixedly connected to the protective blocks 26 so that it can slide stably on the slide rail rack 10. The top of the frame 1 is fixedly connected to the hydraulic rod 25. The inner side of the circular hole 22 is slidably connected to the outer wall of the support cylinder 23. When the hydraulic rod 25 moves downward, it prevents the spring 9 from deforming and thus failing to rebound.

[0039] Specifically, when changing the tool 16, it slides through the slide rail rack 10. The protective block 26 can play a stabilizing role. When the hydraulic rod 25 is pressed down, the sliding block 4 will move downward along with the circular hole 22 on it, passing through the support cylinder 23 to prevent the spring 9 from deforming due to excessive pressure.

[0040] Working principle: When the steel plate bending machine needs to change the tool 16, first start the motor 12, then the gear 11 on the motor 12 rotates on the slide rail rack 10, and then the sliding buckle 3 slides on the slide rail rack 10. At this time, the sliding block 4, which is slidably connected to the sliding buckle 3, will move with the sliding buckle 3. When the sliding buckle 3 reaches the base 24, turn off the motor 12, and then start the motor 2 15 to drive the threaded rod 2 6 to rotate. Then the nut 1 7 on the threaded rod 2 6 rotates together with the support cylinder 1 17 and its connecting plate 18, thereby separating the clamping plate 5 from the tool 16. At this time, the tool 16 can be replaced, realizing the flexibility of replacing tools 16 of different sizes, reducing the wear of the tool 16, and ensuring the processing accuracy.

[0041] When angle adjustment is required, first turn the rotary switch 205 to separate it from the multi-angle mold 206, then start the motor 212, which drives the disc 211 to rotate. At this time, the positioning block 210 and the rotating shaft 209, which are fixedly connected to the disc 211, rotate together. The connecting block 208 connected to the other side of the rotating shaft 209 and the fixing column 207 fixedly connected to it rotate upward, thereby driving the multi-angle mold 206 to rise. At this time, the angle can be adjusted, realizing the flexibility of angle change when facing different angle bends, meeting the needs of diversified processing, and improving production efficiency.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
