Description

Technical Field

[0001] The utility model relates to the technical field of plate shears, in particular to an automatic cutting plate shear. Background Art

[0002] Automatic shearing machine is a mechanical device used to cut and shear plates. This device has many advantages, such as: improving production efficiency, faster and more consistent than manual operation. Ensuring the accuracy and quality of cutting and shearing, reducing errors. Reducing the intensity of manual labor. For example, in the metal sheet processing industry, automatic shearing machine can quickly and accurately cut large metal sheets into the required size and shape, providing materials that meet the requirements for subsequent processing procedures. It is widely used in automobile manufacturing, machinery manufacturing and other fields.

[0003] In the prior art, due to the lack of a special cleaning component on the shearing machine, when the plate enters the cutting box for cutting operation, various granular impurities may be attached to the surface of the plate. These granular impurities may include dust, metal debris, tiny solid particles, etc. During the cutting process, these granular impurities will come into contact with the cutting knife along with the plate. When the granular impurities interact with the blade, they may cause various adverse effects on the blade. On the one hand, the hardness of the granular impurities may be relatively high, and during the friction with the blade, the sharpness of the blade will be worn, gradually making the blade blunt, and reducing the cutting efficiency and quality. On the other hand, some sharp granular impurities may form scratches or notches on the blade, further damaging the integrity and durability of the blade. In addition, over time, a large amount of accumulated granular impurities may also block certain parts in the cutting box, affecting the normal operation of the equipment. Therefore, an automatic cutting shearing machine is proposed herein. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 An automatic plate cutting shearing machine includes a cutting box 1, the upper and lower inner walls of the cutting box 1 are both equipped with hydraulic cylinders, and the upper and lower hydraulic cylinders are both equipped with cutting knives. The cutting box 1 is provided with a feed inlet and a discharge outlet, and the upper and lower hydraulic cylinders are both equipped with cutting knives with strong cutting capabilities, and the plates can be accurately cut through their coordinated operation. The hydraulic cylinders and the cutting knives are both well-known components in the technical field, and are not described in detail in this solution.

[0021] A fixed frame 3 is provided at the feed port through a fixed plate 2, and a movable port 6 is provided on the fixed frame 3. A double-headed screw 9 is provided in the movable port 6 through a driving motor, and the double-headed screw 9 can realize bidirectional rotational movement, thereby driving related components to perform corresponding actions. A movable rod 7 is provided in the movable port 6 through a limiting mechanism, and the movable rod 7 is threadedly sleeved on the double-headed screw 9. The movable rod 7 has threads, and the threads are sleeved on the double-headed screw 9, so that the movement can be realized under the rotation of the double-headed screw 9. A limiting plate 4 is provided on the side of the cutting box 1, and a wiping cloth is provided on the surface of the limiting plate 4. The surface of the limiting plate 4 is paved with a wiping cloth, and the wiping cloth can play a role in cleaning the surface of the plate, etc. The wiping cloth is connected to the limiting plate 4 by Velcro, which is convenient for replacing and cleaning the wiping cloth when needed.

[0022] The limiting plate 4 is provided with a slot corresponding to the movable rod 7 , the movable rod 7 is provided with an extrusion groove 11 , a positioning block 12 is provided in the extrusion groove 11 through an extrusion mechanism, and the limiting plate 4 is provided with a positioning hole 8 .

[0023] The limiting mechanism includes a limiting rod 10 installed in the movable opening 6, the limiting rod 10 is parallel to the double-headed screw 9, and the limiting rod 10 slides through the movable rod 7. It plays a role in limiting and guiding the movement of the movable rod 7, ensuring that it can move smoothly along a predetermined straight line direction.

[0024] The extrusion mechanism includes an extrusion spring 13 disposed in the extrusion groove 11, and the two ends of the extrusion spring 13 are elastically connected to the inner wall of the extrusion groove 11 and the outer wall of the positioning block 12. In this way, when positioning is required, the extrusion spring 13 can push the positioning block 12 into the positioning hole 8 to achieve a reliable positioning function.
