[0027] It also includes a collecting chamber 6, which is opened at the lower side of the main body 1, and a plurality of equally spaced blanking grooves 23 are opened above the collecting chamber 6, the blanking grooves 23 are connected to the collecting chamber 6, and the blanking grooves 23 are adapted to the blanking die 5, a collecting box 8 is arranged inside the collecting chamber 6, and a weighing sensor 11 is arranged at the lower end of the collecting chamber 6;

[0028] It also includes a transmission cavity 17, which is opened on one side of the main body 1, and a threaded rod 19 is rotatably arranged at the middle position of the transmission cavity 17. The external thread of the threaded rod 19 is connected with a moving block 21, one end of the moving block 21 extends to the outside of the transmission cavity 17, and the moving block 21 is slidably matched with the transmission cavity 17. A push block 22 is welded on the inner side of one end of the outer side of the transmission cavity 17 for protecting the moving block 21 from rain, and guide rods 20 are welded on the front and rear sides of the transmission cavity 17, and the guide rods 20 penetrate the moving block 21, and the guide rods 20 are slidably matched with the moving block 21;

[0029] It also includes a connecting plate 13, which is welded on both sides of the connecting plate 13, and three are welded on each side at equal distances. A telescopic rod 15 is arranged at the lower end of the connecting plate 13, and a pressing plate 14 is arranged below the connecting plate 13, and the pressing plate 14 is connected to the output end of the telescopic rod 15.

[0030] When the hydraulic cylinder 3 is started, the connecting table 4 will drive the punching die 5 to move downward, and cooperate with the punching groove 23 to complete the punching operation. Before punching, the motor 18 drives the moving block 21 to move horizontally on the guide rod 20 through the threaded rod 19, and then pushes the push block 22 to send the sheet metal raw material into the punching area. When the punching die 5 moves downward, the pressing plate 14 firmly fixes the sheet metal raw material through the telescopic rod 15 and the second spring 16 to ensure accurate punching. The punched sheet metal parts fall into the collection box 8, and are buffered by the lifting plate 9 and the first spring 10. The weighing sensor 11 monitors the weight of the collection box 8 in real time. When the preset standard value is reached, the PLC controller 2 starts the sound and light alarm 12 to remind the operator to take out the material. The operator can easily take out the collection box 8 for unloading by rotating the door 7.

[0031] See also Figure 2 and Figure 3 A motor 18 is provided on one side of the main body 1, and the output end of the motor 18 is connected to the threaded rod 19 through a coupling. The motor 18 can provide stable power output and is directly connected to the threaded rod 19 through the coupling to ensure the accuracy and reliability of power transmission, thereby pushing the moving block 21 to move smoothly along the guide rod 20, thereby achieving accurate pushing of the sheet metal raw material;

[0032] See also Figure 1 A PLC controller 2 is provided on one side of the front end of the main body 1, and the input end of the PLC controller 2 is electrically connected to the output end of the weighing sensor 11. The PLC controller 2, as a central control system, can receive the weight information of the collection box 8 fed back by the weighing sensor 11 in real time, and make judgments and controls according to the preset standard value. Once the preset standard is reached, the sound and light alarm 12 is immediately activated to remind the operator to ensure that the operator can know and handle it in time;

[0033] See also Figure 1 and Figure 2 A sound and light alarm 12 is installed on one side of the upper end of the main body 1, and the input end of the sound and light alarm 12 is electrically connected to the output end of the PLC controller 2. The sound and light alarm 12 can provide obvious visual and auditory signals. Once the PLC controller 2 detects that the weight of the collection box 8 reaches the preset standard, the sound and light alarm 12 is immediately activated to attract the attention of nearby operators, so that they can quickly take measures to unload;

[0034] See also Figure 4 A lifting plate 9 is slidably arranged inside the collection box 8, and the lifting plate 9 is connected to the collection box 8 by a plurality of first springs 10 distributed in a rectangular array. When the sheet metal falls into the collection box 8, the lifting plate 9 will be pressed and move downward, compressing the first spring 10. Through the elastic recovery effect of the first spring 10, the sheet metal is buffered and protected, and the impact and noise on the collection box 8 are reduced;

[0035] See also Figure 4 The outside of the telescopic rod 15 is sleeved with a second spring 16, one end of the second spring 16 is connected to the connecting plate 13, and the other end of the second spring 16 is connected to the pressing plate 14. When the punching die 5 moves down, the pressing plate 14 will first contact the sheet metal raw material. Through the compression of the telescopic rod 15 and the second spring 16, the pressing plate 14 can firmly squeeze and fix the sheet metal raw material, ensuring that it will not move during the punching process, thereby ensuring the accuracy of the punching and the quality of the product;

[0036] See also Figure 1 and Figure 3 A revolving door 7 is installed at the front end of the main body 1. The revolving door 7 is convenient for the operator to quickly open and close, so as to facilitate the collection box 8 to take out and put materials during daily punching processing. The design of the revolving door 7 also ensures the sealing and safety of the main body 1, avoiding safety hazards during the punching process.

[0037] Working principle: when in use, place the sheet metal material on one side of the push block 22, start the motor 18, the motor 18 will drive the threaded rod 19 to rotate through the coupling, the threaded rod 19 will drive the moving block 21 to rotate synchronously, and the moving block 21 will slide with the two guide rods 20, so the moving block 21 will be limited axially, and the rotation of the moving block 21 will be converted into horizontal linear movement, and the moving block 21 will drive the push block 22 to move synchronously when it moves, so that the sheet metal material can be pushed, simulating the effect of manual pushing, improving safety, and at the same time, the remaining waste after punching can be pushed out of the punching area, which is convenient for the next punching. When punching, start the hydraulic cylinder 3, and the output end of the hydraulic cylinder 3 will move the connecting table 4 downward, and the punching die 5 at the lower end of the connecting table 4 is adapted to the punching groove 23 to complete the punching operation, and when the punching die 5 moves downward, the pressing plate 14 will first contact the sheet metal material to compress the telescopic rod 15 and the second spring 16. Under the recovery action, the pressing plate 14 will firmly squeeze the sheet metal raw material at the lower end, which can avoid movement during punching and ensure the accuracy of punching. The punched sheet metal parts will fall into the collection box 8 through the punching groove 23, so that they can be collected centrally through the collection box 8, without the need for multiple manual material collection, thereby improving the processing efficiency. When the sheet metal parts fall into the collection box 8, they will fall on the upper end of the lifting plate 9, so that the lifting plate 9 can move down to squeeze the first spring 10. The first spring 10 can have a certain buffering effect, and the weighing sensor 11 can weigh the overall weight of the collection box 8, and at the same time can transmit the weighing data to the PLC controller 2. The operator can pre-set the standard value. When the preset standard value is reached, the PLC controller 2 will start the sound and light alarm 12, which can attract nearby operators to come and pick up the materials. The collection box 8 can be taken out and unloaded by opening the rotating door 7. The operation is simple and convenient, which is convenient for daily punching processing.
