[0001] This utility model relates to the field of edge cutting blade technology, specifically to a composite angle edge cutting blade. Background Technology

[0002] The compound angle cutting shear blade is an industrial tool used for cutting the edges of sheet metal. It is usually installed on shearing equipment and plays an important role in many industrial fields such as metal processing and sheet metal forming. By accurately cutting the edges of sheet metal, it helps to obtain sheet metal that meets the size and shape requirements, and is one of the key components to ensure product quality and production efficiency.

[0003] However, the existing composite angle cutting shear blades have some problems in practical applications. The adjustment method of the blades is relatively complicated, making it difficult to quickly and accurately adjust the blade angle and position. This results in insufficient adaptability when dealing with boards of different specifications and thicknesses, affecting the cutting effect and efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a composite angle cutting edge shear blade to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A composite angle cutting edge shear blade includes an adjustment assembly and an installation assembly. The adjustment assembly includes a first connecting rod, a second connecting rod, an adjustment component one, and an adjustment component two. The adjustment component one is disposed on the first connecting rod and the second connecting rod, and the adjustment component two is disposed on the adjustment component one.

[0008] Furthermore, in order to better ensure the adjustment effect, the adjustment component includes a first adjustment port and a second adjustment port. The first adjustment port and the second adjustment port are respectively opened at one end of the first connecting rod and the second connecting rod. The interior of the first adjustment port and the second adjustment port are connected by a cross shaft through a bearing.

[0009] Furthermore, to better ensure the limiting effect, the second adjusting component includes an adjusting handle, which is located at the output end of the cross shaft. The two output ends of the cross shaft are equipped with ratchet wheels, and tension springs and limiting rods are provided on both sides of the ratchet wheels, which are engaged with pawls.

[0010] Furthermore, in order to better ensure the limit adjustment effect, the tension spring and the pawl are equipped with a rotating shaft, and the rotating shaft and the limit rod are both connected to the first connecting rod and the second connecting rod.

[0011] Furthermore, in order to better ensure the installation effect of the shear blade, the installation assembly includes installation component one, which is located at one end of the first connecting rod.

[0012] Furthermore, to better ensure the fixing effect of the shear blade, the mounting component includes a blocking block, which is fixedly mounted on the first connecting rod. The shear blade is provided on one side of the blocking block, and a protective pad and a fixing bolt are provided at one end of the first connecting rod. The protective pad is in contact with one side of the shear blade, and the fixing bolt is threadedly connected to the first connecting rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting up adjustment components, the problem of inconvenient adjustment of the cutting blade of the existing composite angle cutting shear is solved. The first and second adjustment ports in adjustment component one are respectively opened at one end of the first and second connecting rods, and a cross shaft is connected inside by bearings, making the angle adjustment of the cutting blade more flexible. The adjustment handle in adjustment component two is set at the output end of the cross shaft.

[0024] 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.

[0025] Example 1: As Figures 1-4 As shown, a composite angle cutting edge shear blade according to an embodiment of the present utility model includes an adjustment component 1 and an installation component 2. The adjustment component 1 includes a first connecting rod 3, a second connecting rod 4, an adjustment component one, and an adjustment component two. One end of the second connecting rod 4 is equipped with a drive motor in actual use. The adjustment component one is disposed on the first connecting rod 3 and the second connecting rod 4, and the adjustment component two is disposed on the adjustment component one.

[0026] The adjustment component includes a first adjustment port 5 and a second adjustment port 6. The first adjustment port 5 and the second adjustment port 6 are respectively opened at one end of the first connecting rod 3 and the second connecting rod 4. The interior of the first adjustment port 5 and the second adjustment port 6 are connected by a cross shaft 7 through a bearing.

[0027] The second adjustment component includes an adjustment handle 8, which is located at the output end of the cross shaft 7. The two output ends of the cross shaft 7 are provided with ratchet 17. The ratchet 17 is engaged with a pawl 9. Tension springs 10 and limit rods 11 are provided on both sides. The tension springs 10 and the pawl 9 are provided with rotating shafts 12. The rotating shafts 12 and the limit rods 11 are both connected to the first connecting rod 3 and the second connecting rod 4.

[0028] Example 2: Figure 1 , Figure 5 As shown, according to an embodiment of the present utility model, a composite angle cutting edge shear blade is provided. The mounting assembly 2 includes a mounting component 1, which is disposed at one end of the first connecting rod 3.

[0029] The mounting component includes a blocking block 13, which is fixedly mounted on the first connecting rod 3. A shear blade 14 is provided on one side of the blocking block 13. A protective pad 15 and a fixing bolt 16 are provided on one end of the first connecting rod 3. The protective pad 15 is in contact with one side of the shear blade 14, and the fixing bolt 16 is threadedly connected to the first connecting rod 3.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In summary, with the aid of the above-mentioned technical solution of this utility model, when adjusting the angle of the shear blade 14 of the composite angle cutting shear, the cross shaft 7 is driven to rotate by an external power source. Since the cross shaft 7 is respectively installed in the first adjustment port 5 of the first connecting rod 3 and the second adjustment port 6 of the second connecting rod 4 through bearings, when the cross shaft 7 rotates, it will drive the first connecting rod 3 and the second connecting rod 4 to rotate relative to each other. This relative rotation can change the opening and closing angle of the shear blade 14 to adapt to the shearing requirements of different plate thicknesses. The adjustment handle 8 is set at the output end of the cross shaft 7. When it is necessary to fine-tune the angle of the shear blade 14, the adjustment handle 8 is moved to make the cross shaft 7 rotate. The two output ends of the cross shaft 7 are provided with ratchet 17, which are engaged with pawl 9. Tension springs 10 and limit rods 11 are respectively provided on both sides of the pawl 9. The tension spring 10 uses its own elasticity to tightly engage the pawl 9 with the ratchet 17, ensuring that the cross shaft 7 can be stably fixed after rotating to the appropriate position, thus achieving precise positioning of the shear blade 14 angle. At the same time, the rotating shaft 12 and the limiting rod 11 are connected to the first connecting rod 3 and the second connecting rod 4. The rotating shaft 12 provides a support point for the assembly of the tension spring 10 and the pawl 9, while the limiting rod 11 restricts the range of motion of the pawl 9, preventing it from swinging excessively and disengaging from the ratchet 17, thus ensuring the stability and reliability of the adjustment process.

[0032] The mounting component 1 of mounting assembly 2 is located at one end of the first connecting rod 3. The blocking block 13 is fixedly mounted on the first connecting rod 3, and a shear blade 14 is provided on one side of the blocking block 13. The blocking block 13 supports and limits the shear blade 14, ensuring that the shear blade 14 maintains a stable position and posture during the shearing process. One end of the first connecting rod 3 is also provided with a protective pad 15 and a fixing bolt 16. The protective pad 15 is in contact with one side of the shear blade 14. During the shearing process, the protective pad 15 can reduce the direct friction between the shear blade 14 and the plate, reduce the wear of the shear blade 14, and also play a certain buffering role to improve the shearing quality. The fixing bolt 16 is threadedly connected to the first connecting rod 3. By tightening or loosening the fixing bolt 16, the entire shearing device can be easily installed on the shearing equipment or disassembled, which facilitates the maintenance and replacement of the equipment.

[0033] Throughout the entire operation of the composite angle edge cutting shear blade 14, the adjusting component 1 and the mounting component 2 work together. The adjusting component 1, through a reasonable mechanical structure, enables rapid and precise adjustment of the angle of the shear blade 14, allowing it to adapt to the shearing needs of plates of different specifications and thicknesses. The mounting component 2 provides stable support and effective protection for the shear blade 14, and ensures that the entire shearing device can be easily and firmly installed on the shearing equipment. In actual shearing operations, the operator first adjusts the appropriate angle of the shear blade 14 using the adjusting component 1 according to the specific conditions of the plate, and then fixes the shearing device on the shearing equipment using the mounting component 2. When the shearing equipment is started, the shear blade 14 cuts the edge of the plate under the drive of the equipment. The protective pad 15 plays a role in protecting the shear blade 14 and improving the shearing quality during the shearing process, while the blocking block 13 ensures the stable shearing of the shear blade 14. All components cooperate with each other to complete the high-quality plate edge shearing task.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
