[0016] like Figure 1 , Figure 4 , Figure 5 and Figure 6The sheet metal processing machine tool shown includes a base plate 1, a work plate 2 fixedly connected to the top of the base plate 1, a placement frame 3 fixedly connected to the top of the work plate 2, a plurality of sheet metal plates 4 arranged inside the placement frame 3, a sliding groove 5 opened on the top of the work plate 2, a movable plate 6 symmetrically arranged on the top of the work plate 2, an electric push rod 8 fixedly connected to the top of the movable plate 6, a clamping plate 9 fixedly connected to the movable end of the electric push rod 8, a connecting plate 15 arranged at the bottom of the work plate 2, a connecting column 7 fixedly connected to the top of the connecting plate 15, the connecting column 7 being inserted into the interior of the sliding groove 5, and the top end of the connecting column 7 being fixedly connected to the bottom of the movable plate 6.

[0017] like Figure 6 As shown, the placement frame 3 is integrally formed, including a frame body and a shelf below. The distance between the upper surface of the shelf and the bottom surface of the frame body is greater than or equal to the thickness of one sheet metal sheet 4, and less than the thickness of two sheet metal sheets 4. When several sheet metal sheets 4 are placed in the placement frame 3, the bottom sheet metal sheet 4 rests on the shelf. After the clamping plate 9 removes the bottom sheet metal sheet 4 from the gap between the shelf and the frame body, the sheet metal sheet 4 above the bottom sheet metal sheet 4 falls onto the shelf, and this cycle continues.

[0018] The inner wall of the clamping plate 9 is adapted to the sheet metal plate 4. A rubber pad 10 is fixedly connected to the inner wall of the clamping plate 9. A first limiting rod 11 is fixedly connected to the side of the clamping plate 9 near the electric push rod 8. The first limiting rod 11 passes through the moving plate 6.

[0019] The machine tool has two movable plates 6, which are located on both sides of the placement frame 3. After the rubber pads 10 are installed on the inner wall of the clamping plate 9, its height is the same as that of the sheet metal 4. The connecting plate 15 can move at the bottom of the working plate 2. When the connecting plate 15 moves, it can drive the movable plate 6 to move through the connecting column 7. When the machine tool is in use, multiple sheet metal 4 can be placed inside the placement frame 3. When processing the sheet metal 4, the electric push rod 8 can be activated. The electric push rod 8 can directly push the clamping plate 9 close to the sheet metal 4. When the two clamping plates 9 clamp the bottom sheet metal 4 in the placement frame 3 at the same time, the connecting plate 15 can be controlled to drive the movable plate 6 to move. When the movable plate 6 moves, it can drive the sheet metal 4 to move through the clamping plate 9, thereby realizing the loading of the sheet metal 4. When the sheet metal 4 is processed, the connecting plate 15 can be controlled to drive the movable plate 6 to move to the end of the working plate 2. Then, the electric push rod 8 can be controlled to drive the clamping plate 9 to retract, thereby realizing the unloading of the sheet metal 4.

[0020] In order for the connecting plate 15 to drive the moving plate 6 to move, such as Figure 1 , Figure 2 and Figure 3As shown, the bottom of the working plate 2 is fixedly connected to the first mounting block 12 and the first motor 16, the first mounting block 12 is rotatably connected to the first lead screw 13, the side surface of the first lead screw 13 is screwed with the first threaded block 14, the top of the first threaded block 14 is fixedly connected to the bottom of the connecting plate 15, and the output end of the first motor 16 is fixedly connected to one end of the first lead screw 13.

[0021] The bottom of the working plate 2 is fixedly connected to a second mounting block 17, and a second limiting rod 18 is fixedly connected to the second mounting block 17. A limiting block 19 is slidably connected to the side surface of the second limiting rod 18, and the top of the limiting block 19 is fixedly connected to the bottom of the connecting plate 15.

[0022] After the first motor 16 is started, the output end of the first motor 16 can drive the first lead screw 13 to rotate. When the first lead screw 13 rotates, the first threaded block 14 will drive the connecting plate 15 to move at the bottom of the working plate 2 due to the influence of the thread engagement. When the connecting plate 15 moves, it can drive the moving plate 6 to move synchronously through the connecting column 7. In addition, when the connecting plate 15 moves, the limiting block 19 will also slide synchronously on the side surface of the second limiting rod 18. The limiting block 19 and the second limiting rod 18 provide a limiting effect for the connecting plate 15, reducing the possibility of the connecting plate 15 deviating during the movement and improving the stability of the connecting plate 15.

[0023] In order for the machining tool 24 to process different positions of the sheet metal 4, such as Figure 1 and Figure 2 As shown, a mounting bracket 20 is fixedly connected to the top of the work plate 2, a second lead screw 21 is rotatably connected inside the mounting bracket 20, a second threaded block 22 is screwed onto the side surface of the second lead screw 21, and a processor 24 is fixedly connected to the bottom of the second threaded block 22.

[0024] The mounting bracket 20 has a limiting groove, and the top of the second threaded block 22 is inserted into the limiting groove. A second motor 23 is fixedly connected to one side of the mounting bracket 20, and the output end of the second motor 23 is fixedly connected to one end of the second lead screw 21.

[0025] After the clamping plate 9 moves the sheet metal plate 4 to below the processor 24, the processor 24 can process the sheet metal plate 4. After the second motor 23 is started, the output end of the second motor 23 can drive the second lead screw 21 to rotate. When the second lead screw 21 rotates, the second threaded block 22 will drive the processor 24 to move due to the influence of thread engagement, so that the processor 24 can process different positions of the sheet metal plate 4.

[0026] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
