[0036] like Figures 1 and 2 As shown, this embodiment provides a shearing device, including a base 1, a driving assembly 2 and a shearing assembly 3, the driving assembly 2 includes a driving member 21; the shearing assembly 3 includes a first tool 31, a second tool 32 and a limiting member 33, the blade of the first tool 31 and the blade of the second tool 32 are opposite and staggered, the first tool 31 and the limiting member 33 are relatively arranged on the base 1, a limiting space is formed between the first tool 31 and the limiting member 33, the second tool 32 is arranged at the output end of the driving member 21, and the driving member 21 is used to drive the second tool 31. The tool 32 enters or moves away from the limited space along the height direction of the limited space. The limit member 33 is used to press the second tool 32 against the first tool 31. When the driving member 21 drives the second tool 32 into the limited space, the blade of the second tool 32 and the blade of the first tool 31 are staggered to complete the shearing of the workpiece to be processed. The limit member 33 makes the second tool 32 close to the first tool 31 during the shearing process, thereby ensuring that the second tool 32 and the first tool 31 are parallel, making the shearing smooth, and being able to make the sheared end surface of the workpiece to be processed flat.

[0037] Furthermore, the blade of the first tool 31 and the blade of the second tool 32 are both V-shaped, which can limit the workpiece to be processed and prevent it from sliding left and right, and the two V-shaped blades shear towards each other at the same time, which is equivalent to four blades working at the same time, thereby improving the shearing speed and efficiency. In addition, the two V-shaped blades are facing each other and staggered, which can avoid squeezing the workpiece to be processed, prevent deformation of the workpiece to be processed, and further ensure the flatness of the end face.

[0038] Furthermore, if Figure 1 and Figure 3 As shown, the first blade surface 311 of the V-shaped blade of the first tool 31 is inclined from top to bottom in a direction away from the second tool 32, and the second blade surface 321 of the V-shaped blade of the second tool 32 is inclined from bottom to top in a direction away from the first tool 31, which can improve the sharpness of the blade and further avoid squeezing the workpiece to be processed, which is beneficial to improving the flatness of the end surface and further improving the quality of the product.

[0039] like Figure 1 、 Figure 2 and Figure 4 As shown, in order to facilitate the installation of the first tool 31, the shearing device also includes a first tool holder 34. The first tool holder 34 is arranged on the base 1. The first tool 31 is detachably connected to the first tool holder 34, so that the first tool 31 is easy to disassemble and replace.

[0040] In this embodiment, the limiting member 33 is connected to the first tool holder 34 at an angle. The first tool 31, the first tool holder 34, and the limiting member 33 together form a U-shaped limiting space. The limiting member 33 can be integrally formed with the first tool holder 34, which has a simple structure and is easy to manufacture. Optionally, the limiting member 33 can also be directly mounted on the base 1, which is not limited here.

[0041] Furthermore, the limiting member 33 is provided with a groove 331 opposite to the cutting edge of the first tool 31 for accommodating the workpiece to be processed. One end of the workpiece to be processed is passed through the groove 331, the limiting space and the cutting edge of the first tool 31 in sequence until it abuts against the positioning member 41, and then the driving member 21 is started to drive the second tool 32 into the limiting space, and the second tool 32 and the first tool 31 jointly complete the shearing.

[0042] In some embodiments, the top of the stopper 33 is provided with a chamfer (not shown in the figure) to facilitate the second tool 32 to enter the limiting space smoothly and avoid being stuck by the stopper 33. Similarly, the top of the first tool 31 is provided with a chamfer (not shown in the figure) to facilitate the second tool 32 to enter the limiting space smoothly and avoid being stuck by the first tool 31.

[0043] In order to facilitate the installation of the second tool 32, the shearing assembly 3 also includes a second tool holder 35. The second tool holder 35 is arranged at the output end of the driving member 21.

One end of the guide rod 23 is connected to the second tool holder 35, and the other end is slidably passed through the mounting frame 22, which can provide guidance for the movement of the second tool holder 35 along the height direction of the limited space to avoid its moving path from being offset, and at the same time, it can prevent the second tool holder 35 from rotating, ensuring that the second tool 32 is parallel to the first tool 31.

[0045] Of course, in other embodiments, one end of the guide rod 23 is connected to the mounting bracket 22 , and the other end is slidably inserted into the second tool holder 35 , which can also achieve the above-mentioned effect.

[0046] Specifically, a guide rod 23 is provided on each side of the driving member 21, so that the movement of the second tool holder 35 is more stable. Optionally, the number of the guide rods 23 can also be set to one, three or five, etc., which is not limited here.

[0048] Furthermore, the shearing device also includes a positioning component 4, which includes a positioning member 41. The positioning member 41 is arranged on the base 1, and the positioning member 41 is arranged opposite to the shearing component 3 along the width direction of the limiting space. One end of the workpiece to be processed can pass through the limiting space and the V-shaped blade of the first tool 31 and abut against the positioning member 41. After the workpiece to be processed is abutted against the positioning member 41, shearing is performed, which can ensure that the length of the product obtained each time of shearing is consistent, and the positioning component 4 has a simple structure and low cost.

[0049] In order to facilitate the production of products of different lengths, the positioning member 41 is slidably connected to the base 1 in a direction close to or away from the cutting assembly 3, and the positioning member 41 can be locked with the base 1. The staff can adjust the distance of the positioning member 41 relative to the cutting assembly 3 and fix the positioning member 41 to the base 1, thereby facilitating the cutting of products of corresponding lengths. In some embodiments, a sliding groove extending along the width direction of the limiting space is provided on one of the positioning member 41 and the base 1, and a slider slidably connected to the sliding groove is provided on the other, which can also achieve a slidable connection between the positioning member 41 and the base 1.

The other end of the fastener 43 is used to press and fix the sliding member 42 on the base 1. When it is necessary to adjust the distance between the positioning member 41 and the shearing assembly 3, the fastener 43 is first loosened, then the sliding member 42 is slid along the width direction of the limiting space, and finally the fastener 43 is tightened to fix the sliding member 42 on the base 1. In this embodiment, the fastener 43 is a butterfly screw, which is convenient for manual tightening operation. Optionally, the fastener 43 can also be a bolt, etc., which is not limited here.

[0051] In this embodiment, there is only one fastener 43, the width direction of the confining space is consistent with the side direction of the base 1, and the sliding member 42 is engaged with the side of the base 1, thereby providing a guide for the sliding of the sliding member 42. Optionally, at least two fasteners 43 can be provided along the width direction of the confining space, or a sliding groove extending along the width direction of the confining space can be provided on one of the positioning member 41 and the base 1, and a slider slidably connected to the sliding groove can be provided on the other, which can also achieve a guiding effect on the sliding member 42. This is not limited here.
