[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model will be further described below in conjunction with the accompanying drawings of the specification.

[0026] The utility model provides the following technical solutions:

[0027] As attached Figure 1-3 As shown, the utility model discloses a blade formed by stamping, wherein the blade 1 is formed into a collapsed angle band 2 and a bright band 3 by die stamping, and an angle α is formed between the bright band 3 and the bottom of the blade 1. Specifically, in the present design, the blade 1 is stamped to form the bright band 3 and the collapsed angle band 2, and the presence of the collapsed angle band 2 enables the blade to better withstand the cutting force during the cutting process, while the formation of the bright band 3 ensures the smoothness and precision of the blade surface, thereby improving the cutting efficiency and processing quality.

[0028] Furthermore, the collapsed angle band 2 is a portion with rounded corners formed on the top of the blade 1 after the blade 1 is stamped, and the bright band 3 is a portion with a smooth surface formed at the bottom of the collapsed angle band 2 after the blade 1 is stamped. The bright band 3 can be directly used as the working surface of the blade 1. Specifically, in this embodiment, the formation of the bright band 3 makes the surface of the blade 1 smoother, and there is no need for subsequent additional processes to process the bright band 3, thereby improving production efficiency. The setting of the collapsed angle band 2 enables the blade to better withstand cutting forces during the cutting process. Specifically, the fillet angles formed on the collapsed angle band 2 are different according to different stamping requirements.

[0029] Furthermore, the mold includes a movable mold 4 and a static mold 5, wherein the movable mold 4 is arranged above one side of the static mold 5, a processing gap 6 is formed between the movable mold 4 and the static mold 5, the blade 1 is fixed on the static mold 5, one end of the blade 1 extends into the processing gap 6, the movable mold 4 punches the blade 1 in the processing gap 6, and the collapsed angle band 2 and the bright band 3 are sequentially formed on the blade 1 along the punching direction of the movable mold 4. Specifically, in this embodiment, during the punching process, the movable mold 4 applies pressure to compress the blade 1 in the processing gap 6, thereby realizing the formation of the collapsed angle band 2 and the bright band 3. The collapsed angle band 2 is formed by the plastic deformation of the material in the processing gap 6 due to the punching action of the movable mold 4 on the blade 1. The bright band 3 is formed by the friction and extrusion action of the movable mold 4 on the surface of the blade 1, which makes the surface of the material smooth and bright.

[0030] Furthermore, the thickness of the blade 1 is 0.1-0.6 mm, and the width of the processing gap 6 is proportional and inversely proportional to the material thickness ratio of the collapsed angle band 2 and the bright band 3 on the blade 1, respectively, and the thickness ratio of the bright band 3 to the collapsed angle band 2 on the blade 1 is the material thickness ratio. Specifically, in this embodiment, the thickness of the blade 1 is preferably 0.15-0.35 mm, which can not only ensure the strength and durability of the blade 1, but also ensure the uniformity and stability of the material deformation during the stamping process. At the same time, the width of the processing gap 6 has an important influence on the formation of the collapsed angle band 2 and the bright band 3. When the processing gap 6 is small, the stamping effect of the movable mold 4 on the blade 1 is more concentrated, which is conducive to the formation of a more obvious collapsed angle band 2; when the processing gap 6 is large, the stamping effect of the movable mold 4 on the blade 1 is relatively dispersed, and the formation of the collapsed angle band 2 is relatively weak. On the other hand, the formation of the bright band 3 is inversely proportional to the width of the processing gap 6. When the processing gap 6 is smaller, the friction and extrusion effect of the movable mold 4 on the surface of the blade 1 is stronger, which is conducive to forming a smoother and brighter bright band 3, thereby improving the surface quality of the blade 1, and can enhance the touch and comfort between the user's skin surface and the blade when cutting hair; while when the processing gap 6 is larger, the friction and extrusion effect is weakened, and the formation of the bright band 3 may not be obvious enough.

[0031] Further, when the width of the processing gap 6 is 0.01mm, the material thickness of the collapsed angle band 2 and the bright band 3 on the blade 1 accounts for 8%-10% and 50-60% respectively; when the width of the processing gap 6 is 0.008mm, the material thickness of the collapsed angle band 2 and the bright band 3 on the blade 1 accounts for 6%-8% and 55-65% respectively; when the width of the processing gap 6 is 0.006mm, the material thickness of the collapsed angle band 2 and the bright band 3 on the blade 1 accounts for 5%-7% and 60-70% respectively; when the width of the processing gap 6 is 0.005mm, the material thickness of the collapsed angle band 2 and the bright band 3 on the blade 1 accounts for 4%-6% and 65-75% respectively. Specifically, in this embodiment, the precise control of the material thickness ratio of the collapsed angle band and the bright band is achieved by changing the size of the processing gap. When the machining gap is 0.01mm, the material thickness of the collapsed angle zone accounts for a larger proportion, while the material thickness of the bright zone accounts for a smaller proportion, which is suitable for occasions that require stronger cutting force and higher cutting efficiency. As the machining gap gradually decreases, the material thickness of the collapsed angle zone gradually decreases, while the material thickness of the bright zone gradually increases, which enables the blade to withstand higher cutting forces and maintain higher surface quality during the cutting process. Therefore, according to specific machining requirements and cutting conditions, a suitable machining gap can be selected to prepare blades with different material thickness ratios to meet different cutting requirements.

[0032] Furthermore, the blade 1 also has a fracture portion 7 formed by die stamping, and the fracture portion 7 is formed on the side of the bright band 3 away from the collapsed angle band 2, and the fracture portion 7 is removed by grinding. Specifically, in this embodiment, the fracture portion 7 is a structure naturally formed during the die stamping process, and is located on the side of the bright band 3 away from the collapsed angle band 2. However, the existence of the fracture portion 7 may have an adverse effect on the performance of the blade 1, so it needs to be removed by grinding and other process means. In this way, the overall quality of the blade 1 can be guaranteed, and the needs of actual use can be met.

[0033] Furthermore, the hardness of the blade 1 is less than HV250. Specifically, in this embodiment, the hardness of the blade 1 is controlled within a range less than HV250. Such a hardness range not only ensures the strength and sharpness of the blade 1, but also avoids the problem of increased brittleness due to excessive hardness during the stamping process. Appropriate hardness can ensure that the blade 1 maintains good wear resistance and durability during long-term use, thereby improving production efficiency and work quality.

[0034] Further, the stamping speed of the mold is ≤40m / min, and the stamping frequency of the mold is ≤200 times / min. Specifically, in the present embodiment, by controlling the stamping speed to be below 40m / min and the stamping frequency to be below 200 times / min, during the processing, the stamping speed and stamping frequency of the mold are also important factors affecting the blade forming effect. Appropriate stamping speed and stamping frequency can ensure that the blade obtains uniform pressure distribution and stable deformation process during the stamping process, thereby obtaining an ideal collapsed angle band and bright band. Specifically, when the stamping speed is too fast or the stamping frequency is too high, the blade may be subjected to excessive impact force during the processing, causing uneven deformation of the blade, or even cracks or fractures. When the stamping speed is too slow or the stamping frequency is too low, the blade may be subjected to insufficient pressure during the processing, causing the formation of the collapsed angle band and the bright band to be not obvious or uniform enough. Therefore, by controlling the stamping speed and stamping frequency of the mold, effective control of the blade forming effect can be achieved.

[0035] Furthermore, the angle α is an acute angle. Specifically, in this embodiment, by designing the angle α to be an acute angle, the bright band 3 can be made more prominent, thereby improving the sharpness and cutting performance of the blade 1. The angle α is precisely controlled within the range of 88-90°. Such an angle design helps to optimize the cutting performance and stability of the blade 1. When the angle α is 88°, the sharpness of the blade 1 is significantly improved, and the cutting force distribution is more uniform, thereby improving the durability and service life of the blade 1. As the angle α gradually increases, the sharpness of the blade will decrease, but the cutting stability will be enhanced.

[0036] Furthermore, after the blade 1 is stamped, the angle between the bright band of the blade 1 and the horizontal plane of the top of the fracture portion is 88-90°, and the angle α is formed between the bottom surface of the blade 1 and the surface of the bright band 3 after the fracture portion 7 is ground.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
