When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0028] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0029] Reference Figure 1 and Figure 2 The utility model proposes a cutting device, including a base 1 and at least a cutting component 2; the cutting component 2 includes a lower die base 21, an upper die base 22 and a cutting piece 23. The lower die base 21 is movably arranged on the base 1. The surface of the lower die base 21 facing away from the base 1 is used to carry materials. The upper die base 22 is movably connected to the lower die base 21 and can move along the axial direction of the lower die base 21 to approach or move away from the lower die base 21. The cutting piece 23 is connected to the upper die base 22 and is used to approach the lower die base 21 as the upper die base 22 moves to cut the material on the lower die base 21.

[0030] In this embodiment, the base 1 serves as the basic support structure of the entire cutting device, providing a stable mounting platform for other components, ensuring that the entire device does not shake or shift during the cutting process, thereby ensuring cutting accuracy and stability.

[0031] In this embodiment, the lower die base 21 is movably arranged on the base 1, which enables the lower die base 21 to be adjusted within a certain range. For example, the lower die base 21 can be moved to a suitable position according to the size and shape of the material to better carry the material.

[0032] Among them, the surface of the lower mold base 21 facing away from the base 1 is used to carry the material. This surface is usually designed according to different material properties and may have anti-slip, anti-static and other functions to ensure that the material will not slide or generate static interference during the cutting process.

[0033] In this embodiment, the upper die base 22 is movably connected to the lower die base 21 and can move along the axial direction of the lower die base 21 to move closer to or away from the lower die base 21. This design allows the upper die base 22 to accurately control the distance between it and the lower die base 21, thereby adapting to cutting materials of different thicknesses.

[0034] The movement of the upper die base 22 can be achieved through a mechanical transmission mechanism (such as a cylinder, a hydraulic cylinder, a screw-nut mechanism, etc.), which can provide stable power and precise motion control.

[0035] In this embodiment, the cutting member 23 is connected to the upper die base 22. As the upper die base 22 moves closer to the lower die base 21, the cutting member 23 cuts the material on the lower die base 21. The shape and size of the cutting member 23 can be designed according to different cutting requirements. For example, it can be a blade, a saw blade, a laser head, etc.

[0036] The material of the cutting element 23 may also be selected according to the properties of the material to ensure cutting efficiency and quality. For example, a carbide blade may be selected for cutting metal materials, while a high-speed steel blade may be selected for cutting plastic materials.

[0037] The working process of the cutting device of the utility model is specifically as follows:

[0038] Place the material to be cut on the surface of the lower die base 21 facing away from the base 1. The movable design of the lower die base 21 allows the position of the material to be adjusted to the optimal cutting position.

[0039] The upper die base 22 moves along the axial direction of the lower die base 21 and gradually approaches the lower die base 21;

[0040] As the upper die base 22 approaches, the cutting piece 23 connected to the upper die base 22 gradually approaches the material on the lower die base 21. When the cutting piece 23 contacts the material, it starts to cut the material;

[0041] When the cutting piece 23 completes cutting of the material, the upper die base 22 moves away from the lower die base 21, takes out the cut material, and prepares for the next cutting.

[0042] The present invention movably arranges the lower die base 21 on the base 1, allowing the lower die base 21 to be adjusted within a certain range. For example, the lower die base 21 can be moved to a suitable position according to the size and shape of the material to better load the material. In addition, the upper die base 22 is movably connected to the lower die base 21 and can move along the axial direction of the lower die base 21 to drive the cutting member 23 toward or away from the lower die base 21, thereby adapting to cutting materials of different thicknesses. This allows the cutting device of the present invention to cut materials of different specifications and shapes, thereby improving the versatility and production efficiency of the device.

[0043] The cutting device of the utility model is suitable for cutting various materials, such as metal, plastic, wood, etc. It can be widely used in manufacturing, processing and other fields to meet the needs of different industries for material cutting.

[0044] In some embodiments, the lower mold base 21 and the base 1 can be articulated in a variety of ways. For example, the lower mold base 21 can be movably mounted on the base 1, and the position of the lower mold base 21 can be adjusted by moving the lower mold base 21 on the base 1. In another example, the lower mold base 21 can be rotatably mounted on the base 1, and the orientation of the lower mold base 21 can be adjusted by rotation. Of course, the above is merely exemplary, and the specific articulation method depends on actual needs and is not limited by the present invention.

[0045] Please refer to Figure 3 In order to adjust the position of the cutting assembly 2 on the base 1 to match the size of the material, in some embodiments, a slide rail 11 is provided on the base 1, and the lower mold base 21 is connected to a slider 12, which cooperates with the slide rail 11 so that the lower mold base 21 can move relative to the base 1.

[0046] The slide rail 11 can be fixedly connected to the base 1 , for example, by welding or bolting, to ensure that the slide rail 11 is firmly mounted on the base 1 and is not easily loosened.

[0047] The slider 12 serves as a tool for the lower die base 21 to move on the slide rail 11. The connection between the slider 12 and the lower die base 21 can be a fixed connection, such as welding, bolt connection, etc., which makes the installation more secure. During the translation process of the cutting component 2, the connection between the slider 12 and the lower die base 21 is not easy to shake and loosen, thereby causing the cutting component 2 to fall over and be bumped and broken.

[0048] In addition, the slider 12 can also be detachably connected to the lower die base 21 for easy disassembly and replacement. Of course, the above is only exemplary, and the specific method depends on actual needs, and the present invention is not limited thereto.

[0049] In this embodiment, the slider 12 cooperates with the slide rail 11 to provide high-precision linear motion, ensuring that the lower die base 21 moves accurately on the base 1. This is very important for ensuring cutting accuracy, especially when cutting materials with strict dimensional requirements. Secondly, the design of the slide rail 11 can provide stable support and guidance for the lower die base 21, so that it will not shake or shift when moving and bearing cutting forces. This helps to improve cutting quality and reduce scrap rate. In addition, the lower die base 21 can be easily moved on the base 1, and the operation is convenient and quick. The position of the lower die base 21 can be adjusted at any time according to production needs to adapt to the size of the current product, thereby enhancing the flexibility of the cutting device and improving production efficiency.

[0050] To improve the efficiency of movement of the cutting assembly 2, the base 1 may include two, three, or four or more slide rails 11. For example, the base 1 may include two slide rails 11 spaced apart from one another. The two slide rails 11, spaced apart along the length of the cutting assembly 2, can jointly bear the weight of the cutting assembly 2. This means that the pressure on each slide rail 11 is reduced compared to that on a single slide rail 11, making the movement of the cutting assembly 2 on the two slide rails 11 smoother and more efficient while preventing damage to the slide rails 11 caused by excessive pressure.

[0051] Similarly, the number of the sliders 12 can be 1, 2, 3 or more. For example, the cutting device includes two sliders 12, please refer to Figure 3 , two sliders 12 are arranged on the two slide rails 11 at intervals, and are respectively connected to the lower die base 21. The use of two sliders 12 to connect the lower die base 21 at intervals can, on the one hand, jointly bear the pressure of the lower die base 21 and avoid damage due to excessive force, and on the other hand, it can improve the smoothness and efficiency of movement. When the cutting assembly 2 needs to be moved to adapt to products of different sizes, the operator can push the two sliders 12 to move on the slide rails 11 and thereby drive the cutting assembly 2 to move. Of course, the above is only for example, and the specific number and layout are determined according to actual needs, and the present utility model is not limited here.

[0052] Please refer to Figure 1 In order to cut the product, the lower die base 21 is provided with a sliding groove 211 along the axial direction, and the upper die base 22 is connected to a sliding rod 221 that slides with the sliding groove 211. The sliding rod 221 can drive the cutting piece 23 of the upper die base 22 to move axially to cut the product.

[0053] The sliding rod 221 can be fixedly connected to the upper die base 22, such as by welding or bolting, to ensure a secure installation; the sliding rod 221 can also be detachably connected to the upper die base 22 to facilitate maintenance and replacement. Specific methods are determined based on needs, and the present invention is not limited thereto.

[0054] In this embodiment, the sliding groove 211 is axially arranged on the lower mold base 21, providing a motion track for the sliding rod 221 of the upper mold base 22. The shape and size of the sliding groove 211 need to match the sliding rod 221 to ensure that the sliding rod 221 can slide smoothly therein.

[0055] The material of the sliding rods 221 typically needs to have high strength and hardness to withstand the pressure and friction during the cutting process. Furthermore, the number and distribution of the sliding rods 221 affect the smooth movement of the upper die base 22. Generally speaking, the greater the number of sliding rods 221 and the more evenly distributed they are, the smoother the movement of the upper die base 22. For example, a sliding groove 211 can be provided at each of the four corners of the lower die base 21, with the upper die base 22 correspondingly connected to the four sliding rods 221. This ensures that the upper die base 22 does not tilt or wobble during movement. When cutting is required, the sliding rods 221, driven by external power, move axially along the sliding grooves 211 of the lower die base 21, thereby driving the upper die base 22 and the cutting element 23 in motion. The movement trajectory of the sliding rods 221 within the sliding grooves 211 determines the direction and distance of movement of the upper die base 22, ensuring that the cutting element 23 can accurately cut the material on the lower die base 21.

[0056] In this embodiment, the cooperation between the sliding rod 221 and the sliding groove 211 can ensure that the movement direction of the upper mold base 22 is always consistent with the axial direction of the lower mold base 21, thereby improving the cutting accuracy of the cutting piece 23 and avoiding problems such as cutting size deviation or uneven cutting surface caused by unstable movement of the upper mold base 22. Moreover, the movement of the sliding rod 221 in the sliding groove 211 is restricted and can only slide along the axial direction, which makes the upper mold base 22 more stable during movement. The adverse effects of the shaking or offset of the upper mold base 22 on the cutting process are reduced, and the reliability and service life of the device are improved. In addition, by adjusting the position of the sliding rod 221 in the sliding groove 211, the relative position of the upper mold base 22 and the cutting piece 23 can be easily changed to adapt to the cutting requirements of materials of different specifications and shapes, making the cutting device more flexible and versatile.

[0057] Please refer to Figure 3 In some embodiments, the lower die base 21 of the cutting device provided by the present invention is connected to a rotating shaft 3, and one end of the rotating shaft 3 away from the lower die base 21 can be rotatably disposed on the base 1 so that the lower die base 21 can rotate relative to the base 1.

[0058] First, determine the installation location of the rotating shaft 3 on the base 1 and machine the mounting hole or mounting seat to ensure the accuracy and flatness of the installation area. Mount one end of the rotating shaft 3 on the base 1, ensuring that the rotating shaft 3 can rotate freely and that the axial and radial runout are within the allowable range. Connect the lower die base 21 to the other end of the rotating shaft 3, either by welding or bolting, to ensure a secure and reliable connection. This ensures that when the cutting assembly 2 rotates, the connection between the rotating shaft 3 and the lower die base 21 will not loosen due to shaking, causing the cutting assembly 2 to tip over and be damaged.

[0059] In this embodiment, the rotating shaft 3 serves as a key component connecting the lower die base 21 and the base 1. It transmits power and achieves rotational motion. It is typically made of high-strength metal to ensure it withstands the weight of the lower die base 21 and the material, as well as the pressure during cutting, without deformation or damage.

[0060] When the angle or direction of the lower die base 21 needs to be adjusted, the rotary shaft 3 is driven by an external power source (such as a motor or manual operation), which drives the lower die base 21 to rotate together, thereby achieving the rotational movement of the lower die base 21 relative to the base 1. The rotation of the lower die base 21 allows the material to be cut at different angles and directions, thereby meeting the cutting needs of more complex shapes and increasing the cutting flexibility and versatility of the cutting device.

[0061] It should be understood that the base 1 is provided with a rotation support structure that cooperates with the rotating shaft 3, typically including bearings, bushings, or other similar components. These components function to reduce friction between the rotating shaft 3 and the base 1, allowing the rotating shaft 3 to rotate smoothly, while also being able to bear the weight of the rotating shaft 3 and the lower mold base 21.

[0062] Please refer to Figure 1 and Figure 3 In some embodiments, at least two groups of cutting components 2 are provided, and at least two groups of cutting components 2 are arranged side by side and spaced apart.

[0063] In this embodiment, the cutting device is provided with at least two groups of cutting components 2, which increases the cutting capacity and efficiency of the device, can cut multiple materials at the same time, or perform multiple cutting processes on the same material, greatly shortening the production time.

[0064] At least two sets of cutting assemblies 2 are arranged side by side, making the overall layout of the device more compact and reasonable. This design can fully utilize space, reduce the device's footprint, and facilitate operation and maintenance for operators. Furthermore, the spacing can prevent interference between adjacent cutting assemblies 2, ensuring that each cutting assembly 2 can perform cutting work independently.

[0065] It should be noted that multiple cutting assemblies 2 can operate simultaneously or be controlled separately as needed to achieve different cutting modes. For example, multiple cutting assemblies 2 can be set to work in a synchronized mode to continuously cut the same long strip of material, thereby improving production efficiency; or different cutting assemblies 2 can be set to different cutting parameters to cut the same material into different shapes and sizes.

[0066] In some embodiments, the lower die bases 21 of at least two sets of cutting assemblies 2 are arranged at the same height.

[0067] The equal height arrangement of the lower die base 21 ensures that the material is at the same height across the different cutting assemblies 2 during the cutting operation, thereby improving cutting accuracy and consistency. This is particularly true for situations where multiple materials need to be cut simultaneously or large materials need to be cut in sections, ensuring accurate cut dimensions.

[0068] In this embodiment, the lower die base 21 of the two cutting components 2 is connected to a rotating shaft 3. The cutting component 2 can be rotated on the base 1 through the rotating shaft 3 to change the orientation of the cutting component 2, and then the two cutting components 2 can be combined to cut out products of different shapes, such as isosceles trapezoids, right-angled trapezoids, rectangles, triangles, etc.

[0069] In some embodiments, the cutting device further includes a driving member, which is in transmission connection with the lower die base 21 so as to drive the lower die base 21 to rotate relative to the base 1 .

[0070] Among them, according to the size, weight and required rotation speed and torque of the lower die base 21, the driving member can be selected from an electric motor, a hydraulic motor or a pneumatic motor, etc. Specifically, it depends on actual needs and the present invention does not limit it here.

[0071] When the cutting direction of the cutting assembly 2 needs to be adjusted, the lower die base 21 is rotated by the driving member, thereby driving the upper die base 22 to rotate synchronously, thereby changing the angle of the cutting member 23 to perform cutting operations in different directions, and being able to cut products of different shapes.

[0072] Please refer to Figure 3 In some embodiments, a pointer 52 or a pointer 52 assembly 5 for displaying the rotation angle of the lower mold base 21 is provided between the base 1 and the lower mold base 21. The pointer 52 or the pointer 52 assembly 5 includes a dial 51 and a pointer 52 respectively provided on the base 1 and the lower mold base 21. One of the dial 51 and the pointer 52 can rotate relative to the other as the lower mold base 21 rotates.

[0073] In this embodiment, a dial 51 and pointer 52 are mounted on the base 1 and lower die base 21, respectively, forming an intuitive angle display system. The dial 51 is typically a circular or curved surface marked with angle scales, which accurately display the rotation angle of the lower die base 21. The pointer 52 is a slender component, one end of which is fixed to the base 1 or lower die base 21 where the dial 51 is located, and the other end points to the scale on the dial 51, moving as the lower die base 21 rotates.

[0074] One of the dial 51 and the pointer 52 rotates relative to the other as the lower die base 21 rotates. This design ensures that the pointer 52 accurately indicates the rotation angle of the lower die base 21. For example, if the dial 51 is fixed to the base 1, the pointer 52 will rotate relative to the dial 51 as the lower die base 21 rotates, thereby displaying the rotation angle of the lower die base 21. Conversely, if the pointer 52 is fixed to the base 1, the dial 51 will rotate relative to the pointer 52 as the lower die base 21 rotates, similarly achieving angle display.

[0075] When the rotating shaft 3 connected to the lower die base 21 drives the lower die base 21 to rotate relative to the base 1, relative motion occurs between the dial 51 and the pointer 52 fixed to the base 1 or the lower die base 21. The pointer 52 moves on the dial 51 as the lower die base 21 rotates. By reading the angle value on the dial 51 indicated by the pointer 52, the operator can accurately understand the rotation angle of the lower die base 21. This angle display method is intuitive and accurate. Without the need for other complex measuring tools, the rotation status of the lower die base 21 can be monitored at any time during the cutting process, making it easier for the operator to adjust and control, thereby achieving precise cutting of the material. In particular, when angle cutting or cutting of complex shapes is required, accurate angle display can ensure that the relative position of the cutting member 23 and the material is accurate, improving cutting accuracy and quality.

[0076] Please continue to refer to Figure 3 In some embodiments, at least one set of limiting components 4 for limiting the rotation angle of the lower mold base 21 is provided between the base 1 and the lower mold base 21. The limiting components 4 include limiting rods and arc-shaped limiting holes 41 respectively provided on the base 1 and the lower mold base 21. The curvature of the arc-shaped limiting hole 41 is consistent with the rotation direction of the lower mold base 21. The limiting rod and the arc-shaped limiting hole 41 cooperate to limit the rotation angle of the lower mold base 21.

[0077] In this embodiment, the limiting assembly 4 comprises a limiting rod and an arcuate limiting hole 41, respectively provided on the base 1 and the lower die base 21. The limiting rod is typically a slender rod-shaped component fixed to the base 1 or the lower die base 21. The arcuate limiting hole 41 is a hole with a specific curvature, provided on the base 1 or the lower die base 21 at a position corresponding to the limiting rod.

[0078] In this embodiment, the curvature of the arc-shaped limiting hole 41 aligns with the rotational direction of the lower die base 21. This ensures that the movement of the limiting rod within the arc-shaped limiting hole 41 accurately reflects the rotation angle of the lower die base 21. The cooperation between the limiting rod and the arc-shaped limiting hole 41 limits the rotational angle range of the lower die base 21, preventing excessive rotation of the lower die base 21, which could result in inaccurate cutting or damage to the equipment.

[0079] In this embodiment, at least one set of position-limiting assemblies 4 is provided between the base 1 and the lower mold base 21. This can limit the rotation angle of the lower mold base 21 from different directions, thereby improving the reliability and stability of the position-limiting mechanism. For example, a set of position-limiting assemblies 4 can be provided on either side of the base 1 to limit the rotation of the lower mold base 21 from two directions, ensuring that the lower mold base 21 rotates within a specified angular range.

[0080] When the rotary shaft 3 connected to the lower die base 21 drives the lower die base 21 to rotate relative to the base 1, the limiting rods fixed to the base 1 or the lower die base 21 will move within the arc-shaped limiting holes 41. When the limiting rods move to the ends of the arc-shaped limiting holes 41, they will prevent the lower die base 21 from rotating further, thereby limiting the rotation angle of the lower die base 21.

[0081] In this embodiment, the rotation angle of the lower die base 21 can be accurately controlled by the limit component 4, so as to avoid excessive rotation of the lower die base 21 and change in the relative position of the cutting piece 23 and the material, thereby improving the cutting accuracy and quality. Especially when precise angle cutting is required, the role of the limit component 4 is particularly important.

[0082] It should be understood that the operator can set the rotation angle range of the lower die base 21 by adjusting the position of the limit rod within the arc-shaped limit hole 41 according to actual needs. For example, the limit rod can be moved to the middle of the arc-shaped limit hole 41 to allow the lower die base 21 to rotate freely within a certain angle range; or the limit rod can be moved to both ends of the arc-shaped limit hole 41 to limit the rotation angle of the lower die base 21 to a smaller range.

[0083] The above are only some or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
