A support frame is fixedly connected to the top of the base, and a hydraulic cylinder is mounted on the top of the support frame. A connecting rod is fixedly connected to the piston rod of the hydraulic cylinder, and a cutter head is fixedly connected to one end of the connecting rod.

Furthermore, it lacks protection against flying debris, which can easily cause injury to nearby personnel during the shearing process, making it unsafe to use. Utility Model Content

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a safety shearing limiting device, such as Figure 1-4 As shown, the safety shearing limiting device includes: a support plate 1, with two mounting slots on the top of the support plate 1; a support frame 2 fixedly mounted on the top of the support plate 1; a shearing machine 3 mounted on the support frame 2; two first screws 4 rotatably mounted on the inner walls of the two mounting slots respectively, with the ends of the two first screws 4 extending to the outside of the support plate 1; two connecting blocks 5 threadedly mounted on the two first screws 4 respectively, with the two connecting blocks 5 slidably connected to the inner walls of the two mounting slots respectively; two limiting mechanisms for fixing materials respectively assembled on the two connecting blocks 5; and a protective mechanism mounted on the support frame 2 for blocking splashes.

[0023] In this embodiment, when the device is in use, the position of the connecting block 5 in the mounting groove can be adjusted by rotating the first screw 4, thereby adjusting the position of the limiting mechanism. This allows the distance between the two limiting mechanisms to be adjusted, enabling them to fix materials of various widths and prevent displacement, thus improving the versatility of the device. After the material is limited, a protective mechanism covers the entire shearing machine 3. This protects the shearing machine 3 from the flying debris generated during the shearing process, effectively reducing the risk of injury to surrounding personnel from flying debris, improving safety, and achieving good results.

[0024] In a further preferred embodiment of this utility model, the limiting mechanism includes: a horizontal plate 6 welded to the top of the connecting block 5, the horizontal plate 6 having a sliding groove; a bidirectional screw 7 rotatably mounted on the inner walls of both sides of the sliding groove, both ends of the bidirectional screw 7 extending to the outside of the horizontal plate 6; two sliders 8 threadedly mounted on the bidirectional screw 7, both sliders 8 being slidably connected to the inner wall of the sliding groove; two clamping plates 9 respectively fixedly mounted on the two sliders 8; and a first motor 16 fixedly mounted on the horizontal plate 6, the output shaft of the first motor 16 being fixedly connected to one end of the bidirectional screw 7.

[0025] In this embodiment, the limiting mechanism is used to fix the material. When fixing, the first motor 16 is started, which drives the bidirectional screw 7 to rotate. The bidirectional screw 7 drives the two sliders 8 to move closer to each other, and the two sliders 8 drive the two clamping plates 9 to move closer to each other, thereby clamping the material to be processed tightly and preventing it from shifting during processing. The limiting effect is good.

[0026] In a further preferred embodiment of the present invention, the protective mechanism includes: a second motor 10 fixedly installed on the top of the support frame 2, a second screw 11 fixedly installed on the output shaft of the second motor 10, and a screw sleeve 12 threadedly installed on the second screw 11; and a baffle plate 13 fixedly sleeved on the screw sleeve 12, the baffle plate 13 being in contact with the support frame 2.

[0027] In this embodiment, the protective mechanism is used to block flying debris. When in use, the second motor 10 is started, which drives the second screw 11 to rotate. The second screw 11 drives the screw sleeve 12 to move vertically, and the screw sleeve 12 drives the shielding plate 13 to move vertically until the bottom of the shielding plate 13 contacts the material. Then, with the cooperation of the support frame 2, the entire shearing machine 3 can be covered. In this way, the shearing machine 3 can block the flying debris generated during the shearing process, effectively reducing the risk of injury to surrounding personnel from flying debris and improving the safety of use.

[0028] In a further preferred embodiment of the present invention, a plurality of sliding rods 14 are fixedly installed on the top of the support frame 2, and the plurality of sliding rods 14 are slidably connected to the baffle plate 13.

[0029] In this embodiment, through the sliding connection between the slide rod 14 and the baffle plate 13, the baffle plate 13 can remain stable during movement and is not easy to shake or tilt, thereby improving the stability of the entire protective mechanism.

[0030] In a further preferred embodiment of the present invention, anti-slip pads 15 are fixedly installed on one side of each of the plurality of clamping plates 9, and the plurality of anti-slip pads 15 are all made of rubber.

[0031] In this embodiment, by using the anti-slip pad 15, when the clamping plate 9 clamps the material to be processed, the anti-slip pad 15 can provide additional friction, thereby enhancing the clamping effect and preventing the material from sliding or shifting during the shearing process.

[0032] In a further preferred embodiment of the present invention, handwheels are fixedly installed at the ends of the two first screws 4 that are far apart from each other, and a support base is fixedly installed at the bottom of the support plate 1.

[0033] In this embodiment, handwheels are fixedly installed at the ends of the two first screws 4 that are far apart from each other. The design of the handwheels makes it easier for the user to rotate the first screws 4, thereby adjusting the position of the connecting block 5 and the limiting mechanism. A support base is fixedly installed at the bottom of the support plate 1. The support base provides stable support for the entire device, enhancing the stability and reliability of the device.

[0034] In a further preferred embodiment of the present invention, a U-shaped frame is fixedly installed on the top of the support frame 2, and the U-shaped frame is rotatably connected to the second screw 11.

[0035] In this embodiment, a U-shaped frame is fixedly installed on the top of the support frame 2. The U-shaped frame is rotatably connected to the second screw 11. This U-shaped frame provides stable support and rotation environment for the second screw 11, enabling the second screw 11 to rotate smoothly.

[0036] In summary, compared with related technologies, this solution allows users to more conveniently rotate the first screw 4 via a handwheel, thereby adjusting the position of the connecting block 5 within the mounting groove. This allows for adjustment of the distance between the two limiting mechanisms, enabling them to fix materials of various widths and prevent displacement, thus improving the versatility of the device. The clamping action of the limiting mechanisms tightly holds the material to be processed, further enhancing the stability of the material during the shearing process. The protective mechanism covers the entire shearing machine 3, shielding it from flying debris generated during material shearing. This design effectively reduces the risk of injury to surrounding personnel from flying debris, improves safety, and demonstrates good performance.

[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
