[0002] Fasteners are a type of mechanical parts used to firmly connect two or more parts into a whole. Among them, bolts are one of the commonly used fasteners; when producing fasteners, a cutting device is needed to cut them to achieve appropriate use dimensions.

[0003] When the existing cutting device is in use, two clamping blocks are used to squeeze and clamp the fastener to ensure the stability of the fastener during cutting. However, in order to ensure that the fastener is completely cut, the fastener needs to be kept suspended, which results in insufficient supporting force on the fastener. Especially when the fastener is about to be cut off, the insufficient supporting force easily causes the displacement of the fastener during fracture, and then the cross-section of the fastener is not flat enough, affecting the forming effect of the fastener after cutting.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Refer to Figures 1 - 4 , a cutting device for fasteners, including a base 1, and support foot pads 21 are installed at the bottom corners of the base 1. In the actual use process, the support foot pads 21 are anti-slip rubber pads, which can play a role in anti-slip support for the base 1 and ensure the stability of the cutting device during use.

[0028] A strip-shaped seat 2 is arranged above the base 1, and a cutting mechanism is arranged above the middle of the strip-shaped seat 2. Among them, the cutting mechanism includes a cutter 24, the top of the cutter 24 is connected to a lift 25, and the lift 25 is fixed on an L-shaped frame 26. In the actual use process, the lift 25 is one of an electric lift rod, a cylinder, and a hydraulic cylinder, and can drive the cutter 24 to approach or move away from the strip-shaped seat 2, so as to realize the cutting and loading / unloading operations of the fasteners;

[0029] It should be noted that a second guide shaft 27 is provided in parallel on the side of the elevator 25. The bottom of the second guide shaft 27 is fixed to the cutter 24, and the top of the second guide shaft 27 slidably penetrates through the L-shaped frame 26, which can provide guiding effect for the lifting of the cutter 24, so as to ensure the stable lifting of the cutter 24.

[0030] As Figure 1 and Figure 4 shown, cavities 3 are symmetrically formed at both ends inside the bar-shaped seat 2. A lead screw 4 is disposed inside the cavity 3, and the end of the lead screw 4 is rotatably installed at the end of the cavity 3. The relatively remote ends of the two lead screws 4 penetrate through the bar-shaped seat 2 and are connected with a first handle 5. During use, the first handle 5 can be held by hand to provide power for the rotation of the lead screw 4.

[0031] A slot 19 corresponding to the cavity 3 is also formed in the bar-shaped seat 2. Bar-shaped support plates 8 are provided above both ends of the bar-shaped seat 2. The length direction of the support plate 8 is perpendicular to that of the bar-shaped seat 2. A connecting frame 7 is installed at the bottom of the support plate 8. The connecting frame 7 penetrates through the slot 19 and is connected to the moving seat 6, and the moving seat 6 is threadedly installed on the lead screw 4. When the lead screw 4 rotates, the moving seat 6 can move along the axis direction of the lead screw 4 on the lead screw 4.

[0032] Furthermore, a first guide shaft 22 is provided in parallel below the lead screw 4. The end of the first guide shaft 22 is fixed to the end of the cavity 3, and a sliding seat 23 is slidably installed on the first guide shaft 22. The sliding seat 23 is fixed to the moving seat 6, which can provide guiding effect for the movement of the moving seat 6.

[0033] Among them, the slot 19 is formed on both sides of the bar-shaped seat 2, which can avoid waste chips falling into the lead screw 4 in the cavity 3 from the slot 19 during cutting, so as to prevent the waste chips from affecting the movement of the moving seat 6.

[0034] As Figure 1 and Figure 3As shown in the figure, support seats 9 are vertically installed at both ends of the top of the support plate 8. A connecting seat 10 is arranged between the two support seats 9. A screw rod 11 is rotatably installed on one side of the connecting seat 10. The other end of the screw rod 11 penetrates through one of the support seats 9 and is connected with a second handle 12. The screw rod 11 is threadedly connected with the support seat 9. A first clamping plate 13 is vertically installed on the other side of the connecting seat 10. A first limiting groove 14 is formed in the middle of the other end of the first clamping plate 13. Second clamping plates 15 are arranged on both sides of the first clamping plate 13. The second clamping plates 15 are vertically fixed on the other support seat 9. A second limiting groove 16 corresponding to the first limiting groove 14 is formed in the other end of the second clamping plate 15. Among them, both the first limiting groove 14 and the second limiting groove 16 are "V"-shaped grooves. By rotating the screw rod 11, the first clamping plate 13 can be pushed towards the second clamping plate 15, so that the first clamping plate 13 can penetrate between the two second clamping plates 15, thereby reducing the size of the space enclosed by the two limiting grooves, further tightening the end of the fastener, and at the same time providing multi-directional support for the fixed position to ensure the stability of the fastener during cutting.

[0035] Specifically, before cutting the fastener, one end of the fastener is first placed in the second limiting groove 16 therein, and then the corresponding first clamping plate 13 is controlled to approach it to complete the clamping and fixing of one end of the fastener. Subsequently, the lead screw 4 below it moves the fastener below the cutter 24 so that the cutting position of the fastener corresponds to the cutter 24. Then, the lead screw 4 at the other end is adjusted to make another set of clamping plates approach the fastener, and the other end of the fastener is placed in the limiting groove of the clamping plate and fixed again, thereby realizing the fixation of both ends of the fastener. Finally, the elevator 25 can be controlled to descend to complete the cutting of the fastener by the cutter 24.

[0036] In order to further improve the fastening effect after the fastener is placed in the limiting groove, anti-slip rubber pads with elasticity are installed on the inner sides of both the first limiting groove 14 and the second limiting groove 16, which not only enables the fastener to fit more closely with the inner wall of the limiting groove, reducing the shaking of the fastener, but also applies an additional elastic force to the fastened fastener to reinforce the fixation of the fastener.

[0037] During the movement of the connecting seat 10, as Figure 3 shown in the figure, a sliding groove 17 is provided at the bottom of the connecting seat 10. The connecting seat 10 is slidably installed on the sliding rail 18 through the sliding groove 17. The sliding rail 18 is fixed on the support plate 8 along the axial direction of the screw rod 11, which can guide the movement of the connecting seat 10. Because it is rotatably connected with the screw rod 11, the sliding rail 18 also limits the connecting seat 10, enabling the connecting seat 10 to perform a linear motion while maintaining the relative state between the first clamping plate 13 and the two second clamping plates 15.

[0038] During the cutting process, it is inevitable that some waste chips will float and fall into the cavity 3 from the slot 19. Therefore, a strip-shaped groove 20 corresponding to the cavity 3 is opened at the bottom of the base 1, and the strip-shaped groove 20 penetrates through the base 1 and communicates with the cavity 3, allowing the waste chips that fall into the cavity 3 to fall out from the strip-shaped groove 20, so as to prevent them from accumulating in the cavity 3 and causing difficult cleaning.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
