To a certain extent, it improves the use safety of the device, the stamping efficiency and effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a stamping die with a waste cleaning structure and its using method to solve the problem in the prior art that the stamping die lacks an automatic cleaning component, needs to be shut down regularly, and the workbench is cleaned manually, which seriously affects the stamping work efficiency.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A stamping die with a waste cleaning structure and its using method, including a stamping device main body. An electric push rod is installed inside the stamping device main body. A moving block is installed at the output end of the electric push rod. Suction nozzles are embedded at the top and bottom of the moving block. One end of each of the two suction nozzles is installed with a three-way connector. The three-way connector is located inside the moving block. One end of the three-way connector is installed with a dust suction pipe. A waste collection basket and a fan are installed inside the stamping device main body. The fan is located on one side of the waste collection basket. The waste collection basket is located below the electric push rod. The top of the waste collection basket is connected to one end of the dust suction pipe. One end of the fan is installed with a connecting pipe, and one end of the connecting pipe is connected to the waste collection basket.

[0006] Preferably, an operation area is provided on one outer wall of the stamping device main body. A workbench is installed at the top of the operation area. A lower die is installed on the top of the workbench through bolts. Through hole grooves are evenly arranged inside the lower die. Small electric push rods are evenly embedded at the top of the workbench. A ejector pin is installed at the output end of the small electric push rod, and the ejector pin is located inside the through hole groove.

[0007] Preferably, a hydraulic cylinder is installed inside the main body of the stamping device. The output end of the hydraulic cylinder is installed with an adapter plate, and the bottom of the adapter plate is installed with an upper die through bolts. The position of the upper die corresponds to that of the lower die.

[0008] Preferably, a box door is movably installed on the front of the main body of the stamping device. The position of the box door corresponds to that of the waste collection basket. An operation panel and a controller are installed on the front of the main body of the stamping device. The operation panel is located above the box door, and the controller is located on one side of the box door.

[0009] Preferably, an opening groove is provided on the outer wall of one side of the main body of the stamping device, which is used to facilitate the movement of the moving block and the suction nozzle.

[0010] Preferably, an air outlet is provided on the outer wall of one side of the main body of the stamping device, and a dust-proof net is arranged inside the air outlet.

[0011] Preferably, a power socket is installed on the back of the main body of the stamping device, and the power socket is used to connect to the power supply.

[0012] Preferably, the using method of the stamping die includes the following steps: S1: First, connect the power supply to the power socket. The operator inputs the operation parameters through the operation panel. After fixing the blank on the lower die, the hydraulic cylinder pushes the upper die into the lower die to punch and stretch the blank. S2: After one stamping is completed, first clean the waste. Then start the small electric push rod to push the ejector pin upward to apply a thrust to the blank in the lower die and eject the stamped part from the lower die to facilitate taking the part.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, when the fan is started, the fan serves as the suction source to extract the air in the waste collection basket, and the air in the dust collection pipeline is quickly extracted, thereby forming a negative pressure area in the pipeline. Since the waste collection basket is connected to the suction nozzle through the dust collection pipeline, a negative pressure will be formed at the suction nozzle. Under the action of the negative pressure, the waste attached to the surfaces of the lower die and the upper die is carried by the surrounding air flow into the suction nozzle, and then flows along the dust collection pipeline towards the waste collection basket. After the air flow carrying the waste enters the waste collection basket, due to the relatively large space of the collection basket, the air flow speed will quickly decrease, and the waste is separated from the air flow under the action of gravity and inertia and settles at the bottom of the waste collection basket, reducing the manual cleaning steps, improving the use safety of the device to a certain extent, reducing the downtime for cleaning through automatic cleaning, and improving the stamping efficiency and effect to a certain extent.

[0014] 2. By uniformly applying a thrust force to the stamping part, the present invention can make the forces received by all parts of the stamping part uniform when it leaves the mold, prevent deformation caused by excessive or insufficient local stress, ensure that the stamping part maintains good shape accuracy, effectively reduce such surface defects, improve the surface quality of the stamping part, reduce the demolding time, and thus can shorten the entire stamping production cycle and improve production efficiency.

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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] Please refer to Figure 1 、Figure 2 and Figure 3 An embodiment provided by the present invention: A stamping die with a waste cleaning structure and its use method. A stamping die with a waste cleaning structure and its use method includes a stamping device main body 1. An electric push rod 8 is installed inside the stamping device main body 1. A moving block 7 is installed at the output end of the electric push rod 8. Suction nozzles 10 are embedded at the top and bottom of the moving block 7. One ends of the two groups of suction nozzles 10 are installed with a three-way connector 12. The three-way connector 12 is located inside the moving block 7. One end of the three-way connector 12 is installed with a dust suction pipe 11. A waste collection basket 13 and a fan 14 are installed inside the stamping device main body 1. The fan 14 is located on one side of the waste collection basket 13. The waste collection basket 13 is located below the electric push rod 8. The top of the waste collection basket 13 is communicated with one end of the dust suction pipe 11. One end of the fan 14 is installed with a connecting pipe 15. One end of the connecting pipe 15 is communicated with the waste collection basket 13; The stamping device main body 1 is equipped with an automatic cleaning structure. After one stamping, the upper die 6 returns to its original position. Then the electric push rod 8 operates to push the moving block 7 to move, so that the suction nozzles 10 are moved out of the stamping device main body 1, and the two groups of suction nozzles 10 face the upper die 6 and the lower die 3 respectively. The fan 14 is started. The fan 14 serves as a suction source to extract the air in the waste collection basket 13, and the air in the dust suction pipe 11 is quickly extracted, thus forming a negative pressure area in the pipe. Since the waste collection basket 13 is communicated with the suction nozzles 10 through the dust suction pipe 11, a negative pressure will be formed at the suction nozzles 10. Under the action of the negative pressure, the waste attached to the surfaces of the lower die 3 and the upper die 6 is carried by the surrounding air flow into the suction nozzles 10, and then flows along the dust suction pipe 11 towards the waste collection basket 13. After the air flow carrying the waste enters the waste collection basket 13, due to the large space of the collection basket, the air flow speed will quickly decrease. The waste separates from the air flow under the action of gravity and inertia and settles at the bottom of the waste collection basket 13. A filtering device is provided inside the connecting pipe 15 to filter out impurities and dust, ensuring that the air flow entering the connecting pipe 15 and the fan 14 is clean. The clean air is then discharged into the atmosphere or recycled through the fan 14, reducing the manual cleaning steps, improving the use safety of the device to a certain extent, reducing the downtime for cleaning through automatic cleaning, and improving the stamping efficiency and effect to a certain extent.

[0020] Please refer to Figure 2 and Figure 4, An embodiment provided by the present invention: A stamping die with a waste cleaning structure and its usage method. An operation area is provided on one outer wall of the stamping device main body 1. A workbench 2 is installed on the top of the operation area. A lower die 3 is installed on the top of the workbench 2 by bolts. Through holes 19 are evenly arranged inside the lower die 3. Small electric push rods 17 are evenly embedded in the top of the workbench 2. A ejector pin 18 is installed at the output end of the small electric push rod 17. The ejector pin 18 is located inside the through hole 19; A hydraulic cylinder 4 is installed inside the stamping device main body 1. A connecting plate 5 is installed at the output end of the hydraulic cylinder 4. An upper die 6 is installed at the bottom of the connecting plate 5 by bolts. The upper die 6 corresponds to the position of the lower die 3; The lower die 3 is installed on the workbench 2 by bolts. After installation, the ejector pin 18 is embedded in the through hole 19. The lower die 3 is a concave die. Corresponding to the lower die 3 is the upper die 6. The upper die 6 is a convex die. The upper die 6 directly acts on the blank to cause separation or deformation of the part. The lower die 3 is a part in the stamping die that bears the pressure of the upper die 6 and causes separation or deformation of the blank in its cavity. During stamping, the hydraulic cylinder 4 pushes the upper die 6 into the lower die 3 to perform operations such as blanking and stretching on the blank. After one stamping is completed, waste cleaning is carried out first, and then the small electric push rod 17 operates to push the ejector pin 18 upward to apply a thrust to the blank in the lower die 3 to eject the stamped part from the lower die 3, facilitating part taking. By uniformly applying a thrust to the stamped part, the forces received by each part of the stamped part when leaving the die can be made uniform, preventing deformation due to excessive or insufficient local force, ensuring that the stamped part maintains good shape accuracy, effectively reducing such surface defects, improving the surface quality of the stamped part, reducing the demolding time, and thus shortening the entire stamping production cycle and improving production efficiency.

A dust-proof net is provided inside the air outlet 16; A power socket 23 is installed on the back of the stamping device main body 1 for connecting to a power source; When using this device, the power supply needs to be connected to the power socket 23 first. The operator inputs operation parameters through the operation panel 21 to control the stamping operation. The air outlet 16 facilitates the airflow from the fan 14 to the outside. The dust net is used to prevent dust from entering the main body 1 of the stamping device. The operator regularly opens the box door 20, pulls out the waste collection basket 13, and pours out the waste collected in the waste collection basket 13. After completion, the empty waste collection basket 13 is put back into the main body 1 of the stamping device, and the connecting pipe 15 and the dust suction pipe 11 are reconnected to the waste collection basket 13.

[0022] Working principle: When using this device, the power supply needs to be connected to the power socket 23 first.
