[0002] The cutting blade assembly is used for cutting composite parts. To improve the fit of the joints, the cutting blade angle needs to be adjusted when changing material specifications. Currently, when adjusting the cutting blade, it is necessary to first adjust the blade to the required angle, and then make a linear adjustment until the blade tip enters the blade groove. This adjustment process is limited by the operating space, the cutting blade angle adjustment process is cumbersome and time-consuming, and if the operator adjusts it by himself, it may cause damage to the cutting blade or blade plate. Utility Model Content

[0003] The main purpose of this utility model is to provide a cutting blade adjustment device and a forming machine to solve the problem of the cumbersome cutting blade angle adjustment process in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a cutting blade adjustment device is provided, comprising: a cutting blade having a blade tip for cutting materials; and an adjustment assembly rotatably connected to the cutting blade, wherein the adjustment assembly has an arc-shaped track for adjusting the angle of the cutting blade, the center of the arc-shaped track being located at the blade tip and serving as the rotation center of the cutting blade, and the position of the blade tip remaining unchanged when the cutting blade is adjusted along the arc-shaped track.

[0005] Furthermore, the adjustment assembly includes multiple sequentially rotatably connected adjustment plates, each adjustment plate being set at an angle, and arc-shaped tracks being provided between adjacent adjustment plates and between the adjustment plate at the end of the transmission and the cutting blade.

[0006] Furthermore, the adjustment assembly also includes an adjustment protrusion, one of two adjacent adjustment plates having an arc-shaped track, and the other of two adjacent adjustment plates having an adjustment protrusion, the adjustment protrusion being located within the arc-shaped track and capable of moving along the arc-shaped track; and / or one of the adjustment plate at the transmission end and the cutter having an arc-shaped track, and the other of the adjustment plate at the transmission end and the cutter having an adjustment protrusion, the adjustment protrusion being located within the arc-shaped track and capable of moving along the arc-shaped track.

[0007] Furthermore, the adjusting plate includes a first segment and a second segment that are bent and connected in sequence. The first segment and the second segment are respectively provided with an arc-shaped track and an adjusting protrusion. The adjusting plate is rotatably connected to different adjusting plates through the first segment and the second segment, or to the adjusting plate and the cutting blade respectively.

[0008] Furthermore, there are multiple arc-shaped tracks, and at least one adjustment plate is provided with multiple arc-shaped tracks, with the arc-shaped tracks on the same adjustment plate being parallel to each other.

[0009] Furthermore, the planes containing the arc-shaped tracks on the two adjacent adjustment plates are set perpendicular to each other.

[0010] Furthermore, the cutting blade adjustment device also includes a blade setting component, which is detachably connected to the cutting blade and is used to limit the position of the blade tip.

[0011] Furthermore, one of the cutting tool and the cutting blade has a cutting tool protrusion, and the other of the cutting tool and the cutting blade has a cutting tool recess. The cutting tool protrusion is located inside the cutting tool recess to limit the position of the blade tip.

[0012] Furthermore, the cutting tool includes: a blade body; a blade head connected to the blade body, the blade head having a cutting tip; a clamping member for holding the blade body, the clamping member being movably connected to the blade body, and an adjusting component being rotatably connected to the clamping member.

[0023] To address the cumbersome process of adjusting the cutting blade angle in existing technologies, this utility model provides a cutting blade adjustment device and a forming machine.

[0024] like Figures 1 to 2 The cutter adjustment device shown includes: a cutter 10 having a blade tip 11 for cutting materials; and an adjustment assembly 20 rotatably connected to the cutter 10, the adjustment assembly 20 having an arc-shaped track 21 for adjusting the angle of the cutter 10, the center 22 of the arc-shaped track 21 being located at the blade tip 11 and serving as the rotation center of the cutter 10, the position of the blade tip 11 remaining unchanged when the cutter 10 is adjusted along the arc-shaped track 21.

[0025] In this embodiment, the center 22 of the arc-shaped track 21 is located at the blade tip 11 and serves as the rotation center of the cutting blade 10. This ensures that the rotation center of the cutting blade 10 is precisely positioned at the blade tip 11, guaranteeing that the blade tip 11 remains in its original position without displacement when the cutting blade 10 is adjusted along the arc-shaped track 21. This rotatable connection between the cutting blade 10 and the adjustment assembly 20 allows for flexible angle adjustment of the cutting blade 10 without disassembling it, improving adjustment efficiency. Furthermore, the arc-shaped track 21 effectively solves the problem of repeatedly calibrating the blade tip 11 position during traditional cutting blade adjustments, significantly shortening adjustment time, reducing operational difficulty, and avoiding cutting errors caused by blade tip 11 position deviation, thereby improving the efficiency and quality of composite part cutting operations.

[0026] like Figure 1 , Figure 2 As shown, the adjustment component 20 in this embodiment includes multiple sequentially rotatably connected adjustment plates 23. The adjustment plates 23 are angled together, and arc-shaped tracks 21 are provided between adjacent adjustment plates 23 and between the adjustment plate 23 at the transmission end and the cutting blade 10, thereby achieving multi-dimensional adjustment of the cutting blade 10's angle. Specifically, the adjustment component 20 in this embodiment includes three sequentially connected adjustment plates 23, and each adjustment plate 23 is provided with an arc-shaped track 21. The arc-shaped tracks 21 are angled together, thereby constructing a multi-dimensional adjustment network in space, allowing the cutting blade 10 to rotate along a preset path and thus accurately adjust to the required angle position. Thus, on the one hand, by using this multi-level adjustment plate 23 structural design, the angle of the cutting blade 10 can be adjusted in multiple directions, thereby improving the flexibility of the cutting blade 10 angle adjustment. On the other hand, the arc track 21 ensures that the cutting blade 10 can rotate along the arc trajectory of the preset arc track 21 during the angle adjustment process. In this embodiment, the center of the arc trajectory is set at the blade tip 11, so that the cutting blade can always move around the blade tip 11, ensuring that the position of the blade tip 11 remains unchanged. Therefore, when adjusting the angle of the cutting blade 10, there is no need to reposition the blade tip 11, which greatly improves the efficiency and accuracy of the adjustment. At the same time, the arc track 21 also provides guidance for the rotation of the cutting blade 10. Of course, the number of adjustment plates 23 and the setting angle between the adjustment plates 23 can be set according to actual needs. For example, when the cutting blade only needs to adjust the angle in two mutually perpendicular directions, only two mutually perpendicular adjustment plates 23 with arc tracks 21 can be set.

[0027] like Figure 1As shown, the adjustment assembly 20 in this embodiment further includes an adjustment protrusion 24. One of the two adjacent adjustment plates 23 has an arc-shaped track 21, and the other of the two adjacent adjustment plates 23 has an adjustment protrusion 24. The adjustment protrusion 24 is located within the arc-shaped track 21 and can move along the arc-shaped track 21. Specifically, in this embodiment, the adjustment protrusion 24 is installed within the arc-shaped track 21 and can slide within the arc-shaped track 21, thereby enabling the two adjustment plates 23 to move relative to each other along the arc-shaped track 21, thereby adjusting the cutting angle of the cutter 10. This embodiment also provides a locking member between the adjustment protrusion 24 and the arc-shaped track 21. When the angle of the cutter 10 is adjusted to the correct position, the locking member locks, thereby fixing the position of the adjustment protrusion 24 and the arc-shaped track 21 to fix the position of the cutter 10. When the angle of the cutter 10 needs to be adjusted, the locking member unlocks, thereby allowing the adjustment protrusion 24 to move within the arc-shaped track 21 to adjust the cutting angle of the cutter 10. Optionally, the locking element can be a bolt. In this way, by adjusting the cooperation between the protrusion 24 and the arc-shaped track 21, the position of the blade tip 11 can be kept unchanged when the angle of the cutting blade 10 is adjusted, thereby avoiding the re-alignment step and making it more suitable for working conditions that require frequent adjustment of the angle of the cutting blade 10, ensuring the accuracy and efficiency of the angle adjustment.

[0028] Similarly, the adjusting plate 23 located at the transmission end, connected to the cutting blade 10, is configured similarly with the cutting blade 10. One of the adjusting plate 23 and the cutting blade 10 has an arc-shaped track 21, while the other has an adjusting protrusion 24 located within the arc-shaped track 21 and capable of moving along it. In this embodiment, the adjusting plate 23 at the transmission end is provided with the arc-shaped track 21, and the cutting blade 10 is provided with the adjusting protrusion 24 that can slide within this arc-shaped track 21, thereby achieving relative movement of the cutting blade 10 along this arc-shaped track 21. The locking element is a bolt, located on the side of the adjusting plate 23 at the transmission end away from the cutting blade 10, passing through a threaded hole in the adjusting protrusion 24, thereby achieving locking and unlocking of the arc-shaped track 21 and the adjusting protrusion 24. The adjusting plate 23 located at the end of the transmission refers to the adjusting plate 23 adjacent to the cutting blade 10, that is, the adjusting plate 23 closest to the cutting blade 10. Of course, depending on actual needs, bolts can also be directly set as adjusting protrusions 24, and threaded holes are provided on the cutting blade 10. The bolts pass through the arc-shaped track 21 from the side of the adjusting plate 23 away from the cutting blade 10, and cooperate with the threaded holes on the cutting blade 10. This allows the cutting blade 10 to move along the arc-shaped track 21, and also facilitates the locking and unlocking of the adjusting plate 23 and the cutting blade.

[0029] like Figure 1As shown, in this embodiment, the adjusting plate 23 includes a first segment and a second segment connected by sequential bending. The first and second segments are respectively provided with an arc-shaped track 21 and an adjusting protrusion 24. The adjusting plate 23 is rotatably connected to different adjusting plates 23 via the first and second segments, or to both the adjusting plate 23 and the cutter 10. Specifically, both the first and second segments of the adjusting plate 23 are plate-shaped, and their edges are angled, forming an L-shaped bending structure. A reinforcing block is also provided at the connection between the first and second segments to improve the connection strength. The first segment has an arc-shaped track 21, while the second segment has an adjusting protrusion 24, allowing the adjusting plate 23 to simultaneously connect to adjacent adjusting plates 23 near the first segment and adjacent adjusting plates 23 near the second segment. The adjusting plate 23 located at the end of the transmission is connected to the adjusting plate 23 near the second segment via the adjusting protrusion 24 and to the cutter 10 via the arc-shaped track 21. In this way, on the one hand, the L-shaped arrangement of the adjustment plate 23 allows the arc-shaped tracks 21 on different adjustment plates 23 to form an angle, thereby enabling the adjustment assembly 20 to adjust the angle of the cutter 10 from multiple directions while keeping the blade tip 11 position unchanged, thus increasing the adjustment range of the cutter 10. On the other hand, the setting of the reinforcing block can ensure the strength of the adjustment plate 23, thereby ensuring the stability and reliability of the cutter adjustment device, and thus ensuring the cutting accuracy and quality, improving production efficiency. At the same time, when changing the cutting angle, there is no need to recalibrate the position of the blade tip 11, which can improve the convenience of operation and the accuracy of cutting, thereby reducing production costs. Of course, depending on the actual situation, considering that the adjustment plate 23 far from the cutter 10 is only adjacent to one adjustment plate 23, it is possible to set only the first segment or the second segment, that is, only the arc-shaped track 21 or only the adjustment protrusion 24, so as to achieve an angled connection with the adjacent adjustment plate 23.

[0030] In this embodiment, there are multiple arc-shaped tracks 21, and at least one adjustment plate 23 is provided with multiple arc-shaped tracks 21. The arc-shaped tracks 21 on the same adjustment plate 23 are parallel to each other, thus forming a precise multi-track adjustment system. Specifically, in this embodiment, each adjustment plate 23 is provided with multiple arc-shaped tracks 21. On the one hand, the parallel arrangement of the arc-shaped tracks 21 ensures that the position of the blade tip 11 remains consistent regardless of which track the cutter 10 is adjusted on, avoiding the tedious steps of adjusting the position of the blade tip 11 multiple times, reducing the error rate, and thus greatly improving cutting efficiency and accuracy. On the other hand, the connection between the multiple arc-shaped tracks 21 and the adjustment protrusion 24 can improve the reliability of the connection between the adjustment plates 23 and between the adjustment plates 23 and the cutter 10, ensuring the stability of the cutter 10 during the adjustment process.

[0031] In this embodiment, three adjustment plates 23 are provided, including a first adjustment plate, a second adjustment plate, and a third adjustment plate. The first adjustment plate, which is the one furthest from the cutter 10, has only a first segment with three parallel arc-shaped tracks 21. The second adjustment plate, connected to the first adjustment plate, has two parallel arc-shaped tracks 21, and the third adjustment plate has three arc-shaped tracks 21 connected to the cutter 10. Thus, each adjustment plate 23 has multiple parallel arc-shaped tracks 21, allowing for a stable connection between the adjustment plates 23. This enables the cutter 10 to make more stable angle adjustments in the same direction, ensuring smooth transmission of the cutter adjustment device and improving the accuracy of the cutting operation and the quality of the product. Of course, the number of arc-shaped tracks 21 can be adjusted according to actual conditions, ensuring that the arc-shaped tracks 21 on the same adjustment plate 23 are parallel to each other, and that the centers 22 of the arc-shaped tracks 21 on different adjustment plates 23 are all located at the blade tip 11.

[0032] In this embodiment, the planes containing the arc-shaped tracks 21 on two adjacent adjustment plates 23 are arranged perpendicularly to each other. That is, the planes containing the arc-shaped tracks 21 on two adjacent adjustment plates 23 intersect at right angles, meaning the first and second segments of the same adjustment plate 23 are perpendicular. This increases the adjustment dimensions of the cutting blade 10, allowing its angle to be adjusted in three mutually perpendicular directions. This improves the range of angle adjustment for the cutting blade 10, ensuring its flexibility in multi-dimensional angle adjustment and meeting the needs of multi-angle adjustment.

[0033] like Figure 1 As shown, in this embodiment, the cutting blade adjustment device further includes a blade adjusting member 30, which is detachably connected to the cutting blade 10. The blade adjusting member 30 is used to limit the position of the blade tip 11. Specifically, in this embodiment, the blade adjusting member 30 and the cutting blade 10 are matched in a limiting manner. Before using the cutting blade adjustment device, the blade adjusting member 30 needs to be used to adjust the initial position of the blade tip 11 in the blade groove. After the position of the blade tip 11 is adjusted, the blade adjusting member 30 is disassembled to avoid interference when adjusting the angle of the blade tip 11 later. The subsequent adjustment of the cutting angle of the blade tip 11 relies on the arc-shaped track 21, thereby further ensuring the accuracy and stability of the position of the blade tip 11 when frequently changing the cutting blade 10. Optionally, the blade adjusting member 30 can be bolted to other components. When disassembling the blade adjusting member 30, the bolts can be loosened.

[0034] In this embodiment, one of the blade setter 30 and the cutting blade 10 has a blade-setting protrusion, and the other has a blade-setting recess. The blade-setting protrusion is located within the blade-setting recess to limit the position of the blade tip 11. Specifically, in this embodiment, the blade setter 30 is configured as a rectangular block structure, and the blade setter 30 has a blade-setting recess on the side facing the blade tip 11. The cutting blade 10 has a blade-setting protrusion, thereby installing the blade setter 30 into a predetermined position. The blade-setting protrusion extends into the blade-setting recess and engages with it to adjust the initial position of the cutting blade 10, thereby fixing the position of the blade tip 11 in the blade groove, thus quickly positioning the blade tip 11 to ensure the accuracy of the blade tip 11's position.

[0035] like Figures 1 to 2 As shown, in this embodiment, the cutting blade 10 includes: a blade body 12; a blade head 13 connected to the blade body 12, the blade head 13 having a blade tip 11; and a clamping member 14 for clamping the blade body 12, the clamping member 14 being movably connected to the blade body 12, and the adjusting assembly 20 being rotatably connected to the clamping member 14. Specifically, the blade-setting member 30 has a groove on the side facing the blade tip 11 as a blade-setting recess, and the blade-setting protrusion can extend into the groove; the blade tip 11 is located at the end of the blade head 13 near the material, and the blade head 13 is fixedly connected to the blade body 12. Optionally, an upper clamping fixture for the cutting blade 10 is also provided above the blade body 12, and a lower clamping fixture for the cutting blade 10 is provided below it. In this way, the blade body 12 is clamped and fixed by the upper and lower clamping fixtures, thereby ensuring the stability and safety of the blade body 12 during operation, avoiding interference with other components that could cause damage, and thus improving the reliability of the cutting blade 10. One side of the clamping member 14 is also provided with an adjustment protrusion 24, which is movably connected to the third adjustment plate. In this embodiment, the adjustment protrusion 24 is connected to the third adjustment plate by bolts. The bolts pass through the arc-shaped track 21 and engage with the adjustment protrusion 24. When adjusting the angle, simply loosen the nut, determine the appropriate angle, and then tighten it to fix it. This achieves the relative rotation of the cutter 10 with respect to the third adjustment plate.

[0036] In this embodiment, along the arrangement direction of the blade body 12 and the blade head 13, the cross-section of the blade head 13 is approximately triangular, and gradually converges to a point along the direction close to the material. That is, in terms of the appearance of the blade head 13, the end of the blade head 13 near the material gradually narrows into a near-straight line, and the center 22 of the arc track 21, which is also the rotation center of the cutting blade 10, coincides with the endpoint of the triangle and lies on this straight line, thereby ensuring that the position of the blade tip 11 in the blade groove remains unchanged during the angle adjustment of the cutting blade 10. When the cutting blade 10 cuts the material, a small portion of the straight line contacts the material for cutting and serves as the rotation center of the cutting blade 10. Preferably, the straight section in contact with the material is close to the middle position of the blade tip 11 to ensure cutting quality; the length of this straight section varies depending on the thickness of the material.

[0037] In this embodiment, the cutting blade adjustment device is used as follows: First, the position of the blade tip 11 is determined by the blade setter 30, and then a linear adjustment is performed to adjust the blade tip 11 to a suitable position in the blade groove. No further adjustment is required afterward. When it is necessary to change the cutting angle, simply loosen the locking device and adjust the cutting blade along the arc track 21 to the required angle. During this process, the blade tip 11 moves around a point and does not change its relative position with the blade groove, so there is no need to re-set the blade.

[0038] This application also provides a forming machine including the aforementioned cutter adjustment device. This forming machine, by integrating the cutter adjustment device, ensures that the relative position of the cutter 10 and the cutter groove remains unchanged when adjusting the angle. This allows for rapid adjustment of the cutter 10's angle according to production needs, saving adjustment time, reducing operational difficulty, and extending the service life of the cutter 10, thereby improving production efficiency and product quality.

[0039] It should be noted that "multiple" in the above embodiments refers to at least two.

[0040] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0041] 1. This solves the problem of cumbersome blade angle adjustment process in existing technologies;

[0042] 2. By setting the center of the arc track at the tip of the blade and using it as the rotation center of the cutting blade, the rotation center of the cutting blade is precisely positioned at the tip of the blade. This ensures that when the cutting blade is adjusted along the arc track, the tip of the blade remains in its original position and does not shift.

[0043] 3. On the one hand, the rotatable connection between the cutting blade and the adjustment component ensures that the cutting blade can be flexibly adjusted in angle without disassembling it, thereby improving the adjustment efficiency of the cutting blade. On the other hand, the arc-shaped track effectively solves the problem of repeatedly calibrating the blade tip position during the traditional cutting blade adjustment process, thereby significantly shortening the adjustment time, reducing the difficulty of operation, avoiding cutting errors caused by blade tip position deviation, and thus improving the efficiency and quality of composite part cutting operations.
