[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1 - Figure 2 As shown, an electrical cabinet production shearing device includes: a shearing bed 1, a shearing table 2 is provided on one side of the shearing bed 1, a shearing blade 4 and a pressing elastic plate 5 are provided below the shearing table 2, a processing metal plate 3 is placed on the top of the shearing table 2, and the processing metal plate 3 extends to the other side of the shearing table 2 and contacts the size reserved frame 6.

[0026] When it is necessary to shear the metal plate 3, the metal plate 3 is first placed on the top of the shearing bed 1. Then, the metal plate 3 is pushed under the shearing table 2 and passes through the shearing table 2 to reach the position of the size reservation frame 6. The size reservation frame 6 is set to limit the size of the metal plate 3 that can cross the shearing table 2 and the size of the workpiece to be processed. Then, the pressure plate 5 is pressed and the shearing blade 4 cuts to obtain the required workpiece.

[0027] See attached document Figure 3 - Figure 5The pre-sized frame 6 includes two ground rulers 601. Sliding legs 602 are longitudinally slidably mounted on the top of each ground ruler 601. A horizontal sliding rod 603 is slidably mounted on the top of each sliding leg 602. A lifting rod 604 is slidably mounted on the top of each horizontal sliding rod 603. A chamfered block 605 is detachably mounted on the side of each lifting rod 604 that is furthest from each other. The lifting rod 604 contacts the processed metal plate 3. A limiting rod 606 is vertically slidably mounted on the sliding leg 602 above the horizontal sliding rod 603. A feeding assembly 610 is located on the sliding leg 602 above the limiting rod 606. An internal pulley 608 is fixedly connected to the bottom of the lifting rod 604. A sliding groove is formed on the horizontal sliding rod 603 corresponding to the internal pulley 608, and the internal pulley 608 is slidably mounted inside the sliding groove. A sliding wheel 607 is rotatably mounted inside the upper end of the lifting rod 604, and the top of the sliding wheel 607 contacts the processed metal plate 3.

[0028] According to the above structure, when it is necessary to cut the metal plate 3, the longitudinal sliding leg 602 first takes the distance from the shearing table 2 to the transverse sliding rod 603 as the length that the metal plate 3 needs to be cut. Then, the distance between the two lifting rods 604 is adjusted laterally to adapt to the width of the metal plate 3, thereby lifting it. In this way, when cutting the metal plate 3, as long as the metal plate 3 is parallel and in contact with the limiting rod 606, the required workpiece size can be cut off, improving the accuracy and efficiency of the workpiece size. Among them, the sliding wheel 607 is used to reduce the friction with the metal plate 3, so that the metal plate 3 can slide on the lifting rod 604.

[0029] See attached document Figure 4 - Figure 6 The unloading assembly 610 includes an upper rod 611, which is located above the limiting rod 606. A support block 612 is fixedly connected to the top of the upper rod 611. An unloading handle 613 is rotatably installed inside the support block 612. A sliding limiting block 614 is rotatably installed at the end of the unloading handle 613. A lifting rod 615 is slidably installed at the bottom of the sliding limiting block 614. The end of the lifting rod 615 passes through the upper rod 611 and is fixedly connected to the limiting rod 606. An isolation wheel 617 is rotatably connected inside the lower end of the limiting rod 606. The bottom of the isolation wheel 617 contacts the processed metal plate 3. A blocking tooth 616 is fixedly connected to the bottom of the limiting rod 606 near the shearing bed 1. A locking interface is opened on the lifting rod 604 corresponding to the blocking tooth 616.

[0030] According to the above structure, when the processed metal plate 3 is cut, the lifting rod 615 is moved upward by rotating one end of the unloading handle 613. At this time, the lifting rod 615 drives the limiting rod 606 to slide vertically, so that the limiting rod 606 separates from the lifting rod 604. Then the cut processed metal plate 3 and the required workpiece can be slid to the side away from the shearing bed 1 and stacked. The isolation wheel 617 is used to ensure that the processed metal plate 3 can continue to move on the lifting rod 604 when the limiting rod 606 is pressed down, so that the limiting rod 606 will not contact the lifting rod 604. When the processed metal plate 3 is no longer below the limiting rod 606, the limiting rod 606 can immediately fit with the lifting rod 604. The blocking tooth 616 is used to increase the blocking effect on the processed metal plate 3.

[0031] The working principle of this utility model is as follows: When it is necessary to cut the metal plate 3, the metal plate 3 is first placed on the top of the shearing bed 1, and then the metal plate 3 is pushed under the shearing table 2 and passes through the shearing table 2 to reach the position of the size reservation frame 6. By setting the size reservation frame 6, the size of the metal plate 3 that can cross the shearing table 2 and the size of the workpiece to be processed are limited. Then, the elastic plate 5 is pressed, and the shearing blade 4 cuts to obtain the required workpiece.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
