Description

Technical Field

[0001] This application relates to the field of hydraulic cutting machines, and more particularly to a cutting structure for a hydraulic cutting machine. Background Technology

[0002] A hydraulic cutting machine is a mechanical device that uses the pressure generated by a hydraulic system to cut materials through a mold. The hydraulic pump pressurizes the hydraulic oil and sends it into the hydraulic cylinder, which pushes the piston to move, thereby driving the cutting blade to move up and down to cut the material placed on the worktable. Hydraulic cutting machines have the advantages of high cutting accuracy, high efficiency, and simple operation, and can meet the needs of different customers.

[0003] However, in actual use, changing the cutting blade of existing hydraulic cutting machines is a complex and cumbersome process. It usually requires the use of multiple tools and multiple steps, such as disassembling bolts and nuts that fix the blade. This not only consumes a lot of time and manpower but also increases the labor intensity of the operators.

[0004] Regarding the aforementioned technologies, the inventors believe that hydraulic cutting machines suffer from operational inconvenience when changing cutting blades. Therefore, they have proposed a hydraulic cutting machine cutting structure to solve the above problems. Utility Model Content

[0005] To address the inconvenience of changing cutting blades in hydraulic cutting machines, this application provides a cutting structure for a hydraulic cutting machine.

[0006] The hydraulic cutting machine cutting structure provided in this application adopts the following technical solution:

[0007] A hydraulic cutting machine cutting structure includes a hydraulic cutting device. The hydraulic cutting device has symmetrically arranged lifting shafts on both sides of its top. A mounting frame is movably mounted on the outer surface of each lifting shaft. A cutting blade holder is located below the mounting frame. A blade body is fixedly mounted at the bottom of the cutting blade holder. A first groove is symmetrically formed on both the front and rear sides of the mounting frame. A limit screw is rotatably installed inside the first groove. A second groove is formed at the front and rear ends of the cutting blade holder at positions corresponding to the first groove. The bottom of the limit screw abuts against the bottom surface of the cutting blade holder and is threadedly connected to a limit nut. A material pressing mechanism is also provided below the mounting frame for compacting the material.

[0008] Preferably, the pressing mechanism includes a fixing plate, which is fixedly installed on the outer surface of the mounting frame near the first groove. A fixing rod is fixedly installed at the bottom end of the fixing plate. A hollow rod is sleeved on the bottom of the outer surface of the fixing rod. A limit plate is fixedly installed at the bottom end of the hollow rod. A spring is installed inside the hollow rod extending from the bottom end of the fixing rod.

[0009] Preferably, the first groove and the second groove have the same cross-sectional shape and structure, the limiting screw is located inside the first groove and the second groove, and the first groove and the second groove are mutually engaged with the limiting screw.

[0010] Preferably, guide holes are symmetrically provided on both sides of the upper surface of the mounting bracket, and one side of the outer surface of the lifting shaft is located inside the guide hole, and the lifting shaft and the guide hole are adapted to each other.

[0011] Preferably, the outer diameter of the fixing rod is smaller than the inner diameter of the opening at the top of the hollow rod, the bottom end of the fixing rod extends to the hollow rod and is welded with a fixing baffle, the inner diameter of the opening at the top of the hollow rod is smaller than the outer diameter of the fixing baffle, and the fixing rod and the hollow rod are interlocked.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By setting mutually cooperating groove No. 1 and groove No. 2, as well as limit screws and limit nuts on the mounting frame and cutting blade holder, when changing the blade, simply rotate the limit nut and loosen the limit screw to easily disassemble and install the cutting blade holder and blade body. There is no need to use multiple tools for complicated bolt and nut disassembly operations, which greatly saves the time and manpower for changing the blade, reduces the labor intensity of operators, and also improves the safety when changing the blade.

[0014] 2. Through the cooperation of the fixed plate, fixed rod, hollow rod, limiting pressure plate and spring in the pressing mechanism, the limiting pressure plate can tightly press the material under the action of the spring before cutting, preventing the material from shifting or deforming during the cutting process, thereby ensuring cutting accuracy and reducing the risk of material waste and tool damage.

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a cutting structure for a hydraulic cutting machine. (Refer to...) Figure 1-3 A hydraulic cutting machine cutting structure includes a hydraulic cutting device 1. Lifting shafts 2 are symmetrically arranged on both sides of the top of the hydraulic cutting device 1. A mounting frame 3 is movably mounted on the outer surface of the lifting shafts 2. Guide holes are symmetrically opened through both sides of the upper surface of the mounting frame 3. One side of the outer surface of the lifting shafts 2 is located inside the guide holes. The lifting shafts 2 and the guide holes are mutually compatible. A cutting blade holder 4 is arranged below the mounting frame 3. A blade body 5 is fixedly mounted at the bottom end of the cutting blade holder 4. A groove is symmetrically opened on both the front and rear sides of the mounting frame 3. 6. A limiting screw 7 is rotatably installed inside the first groove 6. The front and rear ends of the cutting blade holder 4 are provided with second grooves 8 at positions corresponding to the first groove 6. The first groove 6 and the second groove 8 have the same cross-sectional shape and structure. The limiting screw 7 is located inside the first groove 6 and the second groove 8. The first groove 6 and the second groove 8 are mutually engaged with the limiting screw 7. The bottom of the outer surface of the limiting screw 7 abuts against the bottom surface of the cutting blade holder 4 and is threadedly connected to the limiting nut 9. A pressing mechanism is also provided below the mounting frame 3 for compacting the material.

[0021] By aligning the second groove 8 on the cutting blade holder 4 with the first groove 6 on the mounting bracket 3 and inserting the limiting screw 7 into the second groove 8, the cutting blade holder 4 can be accurately installed under the mounting bracket 3 because the first groove 6, the second groove 8 and the limiting screw 7 are interlocked. Then, by rotating the limiting nut 9, it moves on the limiting screw 7 and gradually tightens. The limiting nut 9 abuts against the bottom surface of the cutting blade holder 4, thereby firmly fixing the cutting blade holder 4 and the blade body 5 on the mounting bracket 3.

[0022] Reference Figure 2 and Figure 3 The pressing mechanism includes a fixing plate 10, which is fixedly installed on the outer surface of the mounting frame 3 near the first groove 6. A fixing rod 11 is fixedly installed at the bottom of the fixing plate 10. A hollow rod 12 is sleeved on the bottom of the outer surface of the fixing rod 11. A limit plate 13 is fixedly installed at the bottom of the hollow rod 12. A spring 14 is installed inside the hollow rod 12 extending from the bottom of the fixing rod 11. The outer diameter of the fixing rod 11 is smaller than the inner diameter of the opening at the top of the hollow rod 12. A fixing baffle is welded to the bottom of the fixing rod 11 extending into the hollow rod 12. The inner diameter of the opening at the top of the hollow rod 12 is smaller than the outer diameter of the fixing baffle. The fixing rod 11 and the hollow rod 12 are interlocked.

[0023] When the hydraulic cutting device 1 is started, the lifting shaft 2 drives the mounting frame 3 to move downward. The limiting pressure plate 13 of the pressing mechanism first contacts the material placed on the worktable. Since the bottom end of the fixed rod 11 is equipped with a spring 14, when the limiting pressure plate 13 is blocked by the material, the spring 14 will be compressed, so that the limiting pressure plate 13 can tightly press the material.

[0024] The implementation principle of the hydraulic cutting machine cutting structure in this application embodiment is as follows: By aligning the second groove 8 on the cutting blade holder 4 with the first groove 6 on the mounting frame 3 and embedding the limiting screw 7 into the second groove 8, the limiting screw 7 plays a positioning role. Since the first groove 6, the second groove 8 and the limiting screw 7 are interlocked, the cutting blade holder 4 can be accurately installed below the mounting frame 3. Then, by rotating the limiting nut 9, it moves on the limiting screw 7 and gradually tightens. The limiting nut 9 abuts against the bottom surface of the cutting blade holder 4, thereby firmly fixing the cutting blade holder 4 and the blade body 5 on the mounting frame 3. When changing the blade, the limiting nut 9 is rotated in the opposite direction to loosen it and release the fixing of the cutting blade holder 4, so that the cutting blade holder 4 and the blade body 5 can be easily removed, achieving the purpose of quick blade replacement.

[0025] When the hydraulic cutting device 1 is started, the lifting shaft 2 drives the mounting frame 3 to move downward. The limiting pressure plate 13 of the pressing mechanism first contacts the material placed on the worktable. Since the bottom end of the fixed rod 11 is equipped with a spring 14, when the limiting pressure plate 13 is blocked by the material, the spring 14 will be compressed, so that the limiting pressure plate 13 can firmly press the material. Throughout the cutting process, the spring 14 always maintains a certain pressure to ensure that the material will not shift or deform. When the cutting is completed, the lifting shaft 2 drives the mounting frame 3 to move upward. The limiting pressure plate 13 leaves the material under the restoring force of the spring 14, completing one working cycle of pressing and cutting.
