[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0026] See attached Figure 1-4 , a high-efficiency shearing machine, comprising a processing table 1, with limit plates 2 arranged on both sides of the top of the processing table 1, a pushing mechanism 3 is arranged between the two limit plates 2, and a pushing plate 4 driven by the pushing mechanism to intermittently move along the extending direction of the limit plates 2;

[0027] A bracket 5 is also provided on the processing table 1, on which a telescopic cylinder 6 is installed. The telescopic axis of the telescopic cylinder 6 extends vertically downward, and a lifting plate 7 is fixedly installed at the end. A shearing knife 8 is provided at the bottom of the lifting plate 7, and the shearing knife 8 is located above the unloading end of the processing table 1.

[0028] In this embodiment, after the plate to be sheared is placed between the two limit plates 2, the pushing mechanism 3 drives the pushing plate 4 to move intermittently along the extension direction of the limit plate 2, thereby pushing the plate to move synchronously and intermittently. When the plate stops moving, the telescopic cylinder 6 drives the lifting plate 7 to descend until the shearing knife 8 shears the front end of the plate. At this time, the plate continues to move, and the above steps are repeated to achieve automatic continuous shearing, which not only saves labor costs but also improves processing efficiency.

[0029] A collecting box 16 with an open top is placed below the unloading end of the processing table 1 for collecting the cut plates.

[0030] The pushing mechanism 3 includes a motor 301, an incomplete gear 302 is arranged on the rotating shaft of the motor 301, a tooth plate 303 is meshed on the incomplete gear 302, one end of the tooth plate 303 is fixedly connected to the pushing plate 4, and a first slider 304 is fixedly installed on the bottom, the first slider 304 is slidably connected to the first slide groove 101 opened on the top of the processing table 1, and the extension direction of the first slide groove 101 is the same as that of the limit plate 2.

[0031] In this embodiment, after the motor 301 is started, the incomplete gear 302 rotates synchronously. When the gear teeth of the incomplete gear 302 are meshed with the tooth plate 303, the first slider 304 is slidingly connected to the first slide groove 101, and the push plate 4 can be driven to move along the extension direction of the limit plate 2. After the incomplete gear 302 continues to rotate, its gear teeth will disengage from the tooth plate 303, and the push plate 4 will stop moving. Similarly, repeating the above process can realize intermittent movement of the push plate 4 along the extension direction of the limit plate 2.

[0032] The incomplete gear 302 is connected to the rotating shaft of the motor 301 by bolts, so that the incomplete gear 302 with different numbers of teeth can be replaced, thereby changing the intermittent moving distance of the push plate 4 to shear into plates of different specifications.

[0033] A second slider 9 is fixedly installed at the bottom of the limiting plate 2, and the second slider 9 is slidably connected to a second slide groove 102 opened on the top of the processing table 1. The extension direction of the second slide groove 102 is perpendicular to the first slide groove 101, and a screw rod 10 is rotatably installed inside, and the screw rod 10 is threadedly connected to the second slider 9, and a handle 11 is installed at the end.

[0034] In this embodiment, after holding the handle 11 and rotating it, the screw rod 10 synchronously rotates in the second slider 9, and then cooperates with the sliding connection between the second slider 9 and the second slide groove 102 to drive the second slider 9 to slide in the second slide groove 102, and the limit plate 2 keeps moving synchronously, so that the distance between the two limit plates 2 can be adjusted, which is used to limit plates of different specifications.

[0035] A guide slide rod 12 extending in the vertical direction is slidably mounted on the lifting plate 7 , a spring 13 is arranged on the guide slide rod 12 , a limit block 14 is arranged on the top, and a pressure block 15 is fixedly mounted on the bottom.

[0036] In this embodiment, the telescopic cylinder 6 drives the lifting plate 7 to descend, and the pressure block 15 descends synchronously, first abutting against the plate. When the shearing knife 8 shears the plate, the pressure block 15 cooperates with the spring 13 and the sliding of the guide slide rod 12 on the lifting plate 7, so that it can always abut against the plate, so as to improve the stability of the shearing knife 8 when shearing the plate.

[0037] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.

[0038] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art.
