[0002] Shearing machine is a kind of machine tool, it adopts hydraulic drive, reliable safety performance and easy operation. Shearing machine is suitable for metal recycling processing plants, scrap car dismantling yards, smelting and casting industries, and can perform cold shearing, pressing and flanging of various shapes of steel and various metal materials, as well as pressing and forming powder products, plastics, fiberglass, insulation materials, and rubber. Shearing machine is divided into different types: metal shearing machine, combined punching and shearing machine, hydraulic shearing machine and bar shearing machine. The most commonly used metal shearing machine is crocodile shearing machine and gantry shearing machine.

[0003] Existing shearing machines lack plate positioning components when in use. During the shearing process, the plates are not effectively positioned and fixed, which may cause the plates to shake or shift during the shearing process, which not only affects the shearing accuracy and effect, but may also cause damage to the shearing machine itself. In addition, it can only be applied to plates of one or several specific specifications, and cannot limit plates of different sizes and thicknesses, which not only increases the difficulty and time cost of operation, but may also affect production efficiency.

[0004] How to invent a new positioning mechanism to reduce the shearing damage of the plate to improve these problems has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0023] Example

[0024] Reference Figure 1-3A new positioning mechanism for reducing the shearing damage of a plate includes a mounting plate 1, on which a limiting slide groove 101 and a cutting groove 102 are respectively provided. The arrangement of the mounting plate 1 can effectively prevent the plate from shaking during cutting. A fixing platform 2 and a fixing seat 8 are respectively fixed on the mounting plate 1 at the end of the limiting slide groove 101. A motor 6 is fixedly connected to the left wall of the fixing platform 2. A lead screw 601 is fixedly connected to the output end of the motor 6. The lead screw 601 is rotatably connected between the fixing platform 2 and the fixing seat 8. A limit rod 602 is fixedly connected between the fixed platform 2 and the fixed seat 8, two limit slides 7 are arranged between the fixed platform 2 and the fixed seat 8, and the two limit slides 7 are both slidably connected to the inside of the limit slide groove 101, one of the limit slides 7 is threadedly connected to the lead screw 601, and the other limit slide 7 is slidably connected to the limit rod 602, and a connecting plate 9 is fixedly arranged between the two limit slides 7, and elastic limit devices are arranged at the upper ends of the fixed platform 2 and the limit slide 7, which can limit plates of different thicknesses;

[0025] It should be noted that the height of the bottom side wall of the cutting groove 102 is higher than the height of the connecting plate 9, so as to avoid the cutting device from damaging the connecting plate 9 when cutting the plate.

[0026] Reference Figure 3-4 The elastic limiting device includes a connecting rod 4 and a U-shaped groove provided on the upper ends of the fixed platform 2 and the limiting slide 7. The connecting rod 4 is slidably connected to the inside of the U-shaped groove. The upper end of the connecting rod 4 is fixedly connected to the pull plate 3. The lower end of the connecting rod 4 is fixedly connected to the pressing plate 5. The upper side wall of the pressing plate 5 is elastically connected to the bottom wall of the U-shaped groove through a connecting spring 401. The connecting spring 401 is sleeved on the outer side of the connecting rod 4. The side walls of the pressing plate 5 are fixedly connected to the limiting protrusions 501. The side walls of the U-shaped groove are provided with sliding grooves matching the limiting protrusions 501.

[0027] It should be noted that: both the pressing plate 5 and the U-shaped groove are provided with notches matching the cutting groove 102, ensuring that the cutting device will not be affected when cutting the plate. The height of the cutting groove 102 is greater than the thickness of the mounting plate 1, ensuring that the plate can be effectively cut. The bottom wall of the U-shaped groove is flush with the upper side wall of the mounting plate 1, ensuring the stability of the plate when placed. The gap between the pull plate 3 and the pressing plate 5 is greater than the movable range of the cutting device, which can ensure that during the cutting process, the cutting device will not conflict or rub against the positioning mechanism.

[0028] The working principle of the novel positioning mechanism for reducing the shearing damage of the plate is as follows: when the motor 6 drives the lead screw 601 to rotate, the limit slide 7 will move in the limit slide groove 101 through the connection with the lead screw 601. At the same time, driven by the connecting plate 9, the limit slide 7 on the other side will also slide on the limit rod 602. This moving characteristic allows the positioning mechanism to adapt to plates of different widths. By simply adjusting the movement of the limit slide 7, the positioning of plates of different widths can be achieved.

[0029] When the plate needs to be fixed, the operator can pull the pull plate 3 to lift the pressure plate 5, and place one end of the plate between the lifted pressure plate 5 and the U-shaped groove. Under the elastic force of the connecting spring 401, the pressure plate 5 will apply a stable pressure to the plate to ensure that the plate is firmly positioned in the U-shaped groove to prevent it from moving or sliding during the shearing process. Since both the pressure plate 5 and the U-shaped groove are designed with notches that match the cutting groove 102, this ensures that the plate will not be damaged by the limiting device during the positioning process.

[0030] When the plate is stably positioned, the cutting device can start working. The cutting device can freely move in the cutting groove 102 through its range of motion to perform precise cutting. Since the height of the cutting groove 102 is greater than the mounting plate 1, it ensures that the cutting device will not touch the mounting plate 1 or other fixed parts when cutting deeply, thereby ensuring the accuracy and depth of the cutting.

[0031] The design of this positioning mechanism takes into account plates of different thicknesses and sizes. By adjusting the position of the limiting slide 7 and selecting an appropriate combination of the pressure plate 5 and the U-shaped groove, it can adapt to different plate requirements. The elastic limiting device ensures that a stable limiting effect can be provided for plates of different thicknesses, thereby improving the scope of use and flexibility of the mechanism. This design not only improves shearing accuracy and reduces material damage, but also increases the operability and flexibility of plate cutting.
