Description

Technical Field

[0001] This invention relates to the field of sheet metal pressing technology, specifically to a sheet metal pressing device. Background Technology

[0002] Sheet metal has the characteristics of being lightweight, high-strength, conductive (and suitable for electromagnetic shielding), low-cost, and capable of large-scale mass production, and has been widely used in the fields of electronics, communications, automotive, and medical devices.

[0003] Comparing with existing national patents, a stamping die for automotive body sheet metal parts that facilitates debris removal, patent application number CN202121135148.8, discloses a stamping die for automotive body sheet metal parts that facilitates debris removal. This die includes a die body, with one bottom end of the die body fixedly connected to one side of a support. Square limiting plates are fixedly connected to both ends of one side of the support's top. The middle of the support's top is slidably connected to the bottom end of a trapezoidal connector. This invention utilizes the trapezoidal connector's reciprocating sliding motion under the constraint of the two square limiting plates. This, in turn, causes the mold cleaning component to reciprocate, cleaning the automotive body sheet metal mold area of ​​the stamping die body. This solves the problem that existing automotive body sheet metal stamping dies lack a debris removal structure, requiring manual cleaning by mold operators. Manual cleaning is time-consuming, labor-intensive, and potentially dangerous, thus affecting the processing efficiency of automotive body sheet metal parts.

[0004] The aforementioned patent solves the problem that existing stamping dies for automotive body sheet metal parts do not have a debris removal structure. However, during the pressing process, the debris varies in size, with larger debris taking up space and smaller debris floating in the air, making them difficult to handle. Summary of the Invention

[0005] The purpose of this invention is to provide a sheet metal pressing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sheet metal pressing device, comprising a sheet metal pressing mechanism, wherein the sheet metal pressing mechanism includes a pressing device, an upper mold is fixedly connected to the inner top of the pressing device, a cutting blade is fixedly connected to the outer wall of the upper mold, a collection chamber is fixedly connected to the pressing device, a fixing rod is fixedly connected to the inner wall of the collection chamber, and a lower mold is fixedly connected to the outer wall of the fixing rod, with the lower mold located at the bottom of the upper mold. The sheet metal to be pressed is placed on the lower mold, the pressing device is powered on and started, the pressing device drives the upper mold to descend and press the sheet metal, the cutting blade cuts the excess plate on the outer wall of the lower mold, so that the excess sheet metal is cut off and the cut-off sheet metal debris falls into the collection chamber, the fallen debris falls into the collection chamber through a through hole, the pressing device is fixedly connected to a telescopic extrusion mechanism, and an airflow mechanism is fixedly connected to the inner wall of the lower mold;

[0007] The telescopic extrusion mechanism includes a telescopic machine. When powered on, the telescopic machine drives a telescopic rod to extend and retract. The telescopic rod pulls an L-shaped plate downwards, extruding and extruding debris. A torsion spring is installed inside the first bearing, preventing it from rotating easily. During extrusion, the L-shaped plate extrudes larger debris, causing long, strip-shaped debris to be compressed and folded. An arc-shaped block, following the descent of the L-shaped plate, also compresses the debris, further folding it and reducing its footprint. When the telescopic machine is activated, it moves the L-shaped plate up and down via the telescopic rod. During descent, the L-shaped plate extrudes and bends the strip-shaped debris, reducing its size. The area occupied by the debris is determined by the downward movement of the L-shaped plate and the arc-shaped block. The arc shape of the arc-shaped block compresses the debris, causing it to bend and further bending, thus ensuring the area occupied by the debris. The inner bottom of the pressing device is fixedly connected to the bottom of the telescopic machine. The telescopic machine is movably connected to a telescopic rod, which is inserted into the inside of the collection chamber. The top of the telescopic rod is rotatably connected to two first bearings. The outer wall of each first bearing is fixedly connected to an L-shaped plate. A limit block is fixedly connected to the inner wall of the collection chamber near the L-shaped plate. The L-shaped plate is in movable contact with the limit block. The outer wall of the L-shaped plate has a through hole.

[0008] According to the above technical solution, the outer wall of the L-shaped plate is rotatably connected to a second bearing, and the outer wall of the second bearing is fixedly connected to one end of an elastic rod. The end of the L-shaped plate is pressed against the limiting block, causing the L-shaped plate to rotate. Since the L-shaped plate is L-shaped, the right angle at the bottom of the L-shaped plate will rotate during the rotation process. The right angle of the L-shaped plate will squeeze the debris, causing the debris to bend and thus reducing the floor space. During the movement of the L-shaped plate, the conical block will move to squeeze the debris. The conical shape of the conical block will further squeeze the debris, ensuring that the floor space occupied by the debris is reduced. Moreover, during the rotation of the L-shaped plate, the right angle of the L-shaped plate will move, thereby squeezing the debris at multiple positions, reducing the floor space occupied by the debris, thus reducing subsequent processing steps, and allowing more debris to be stored.

[0009] According to the above technical solution, a conical block is fixedly connected to the other end of the elastic rod. The conical block descends and also presses against the debris, causing the debris to be compressed and accumulated. After the L-shaped plate descends, the end of the L-shaped plate contacts the limiting block. After the end of the L-shaped plate is compressed, the L-shaped plate rotates through the first bearing. During the rotation, the corner of the L-shape of the L-shaped plate moves away from the telescopic rod. During the movement, it drives the second bearing to move, causing the conical block to press into more positions, causing more debris to be compressed and folded, reducing the area occupied by the debris. After one compression, the telescopic machine drives the telescopic rod to rise again. The end of the L-shaped plate away from the first bearing will press against the fixed rod. Then, the L-shaped plate resets during the rising process. Several arc-shaped blocks are fixedly connected to the bottom of the L-shaped plate.

[0010] According to the above technical solution, the airflow mechanism includes a storage compartment, and the storage compartment is fixedly connected to the inner wall of the lower mold.

[0011] According to the above technical solution, the outer wall of the storage compartment is hinged with a door panel, and the outer wall of the storage compartment is fixedly connected with a sponge block.

[0012] According to the above technical solution, an airflow port is provided on the outer wall of the lower mold, and a fan is fixedly connected to the inner wall of the lower mold. When the fan is started, the fan draws airflow from inside the collection chamber through the first pipe, thereby drawing up dust and floating debris, which are then stored in the storage chamber. This reduces the amount of floating debris and the amount of debris inhaled by workers, thus protecting their health. The airflow from the fan is blown out through the airflow port, which blows away dust and debris near the outside of the lower mold, away from the pressing equipment, reducing the amount of debris in the airflow.

[0013] According to the above technical solution, one end of the second pipe is fixedly connected to the outer wall of the fan, and the other end of the second pipe is fixedly connected to the inside of the storage compartment.

[0014] According to the above technical solution, one end of the first pipe is fixedly connected to the outer wall of the fan, and the other end of the first pipe is inserted into the bottom of the lower mold.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When the telescopic machine is started, the telescopic machine drives the L-shaped plate to move up and down through the telescopic rod. During the descent, the L-shaped plate squeezes the strip-shaped debris, causing the debris to bend and reducing the area occupied by the debris. During the descent, the arc-shaped block follows the L-shaped plate and the arc shape of the arc-shaped block squeezes the debris, causing the debris to bend, further bending the debris and ensuring the area occupied by the debris.

[0016] The end of the L-shaped plate is pressed against the limiting block, causing the L-shaped plate to rotate. Because the L-shaped plate is L-shaped, the right angle at the bottom of the L-shaped plate will rotate during the rotation. The right angle of the L-shaped plate will squeeze the debris, causing the debris to bend and thus reducing the footprint. During the movement of the L-shaped plate, the conical block will move and squeeze the debris. The conical shape of the conical block will further squeeze the debris, ensuring that the footprint of the debris is reduced. Moreover, during the rotation of the L-shaped plate, the right angle of the L-shaped plate will move, thus squeezing the debris in multiple positions. The reduction of the debris footprint reduces subsequent processing steps and allows for the storage of more debris.

[0017] When the blower starts, it draws airflow from inside the collection chamber through the first pipe, thereby sucking up dust and floating debris, which is then stored in the storage chamber. This reduces the amount of floating debris and the amount of workers inhaling it, thus protecting their health. The blower airflow is then blown out through the air outlet, which blows away dust and debris near the outside of the lower mold, keeping them away from the pressing equipment and reducing the amount of debris in the airflow.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] Please see Figure 1-3 The present invention provides a technical solution: a sheet metal pressing device, including a sheet metal pressing mechanism 1, the sheet metal pressing mechanism 1 including a pressing device 11, an upper mold 12 fixedly connected to the inner top of the pressing device 11, a cutting blade 13 fixedly connected to the outer wall of the upper mold 12, a collection chamber 15 fixedly connected to the pressing device 11, a fixing rod 16 fixedly connected to the inner wall of the collection chamber 15, and a lower mold 14 fixedly connected to the outer wall of the fixing rod 16, and the lower mold 14 is located at the bottom of the upper mold 12. The sheet metal to be pressed is placed on the lower mold 14, the pressing device 11 is powered on and started, the pressing device 11 drives the upper mold 12 to descend and press the sheet metal, the cutting blade 13 cuts the excess plate on the outer wall of the lower mold 14, so that the excess sheet metal is cut off and the cut sheet metal debris falls into the collection chamber 15, and the fallen debris falls into the collection chamber 15 through the through hole 25. The pressing device 11 is fixedly connected to a telescopic extrusion mechanism 2, and the inner wall of the lower mold 14 is fixedly connected to an airflow mechanism 3.

[0030] The telescopic extrusion mechanism 2 includes a telescopic machine 21. When the telescopic machine 21 is powered on, it drives the telescopic rod 22 to extend and retract. The telescopic rod 22 pulls the L-shaped plate 24 downwards. The descent of the L-shaped plate 24 extrudes the debris. A torsion spring is installed inside the first bearing 23, making it difficult for the first bearing 23 to rotate. When the L-shaped plate 24 extrudes the debris, it extrudes larger debris, causing long, strip-shaped debris to be compressed and folded. The arc-shaped block 244 follows the descent of the L-shaped plate 24 and also presses onto the debris, further folding the debris and reducing its size. The area occupied by the pressing equipment 11 is fixedly connected to the bottom of the telescopic machine 21. The telescopic machine 21 is movably connected to the inside of the telescopic rod 22, and the telescopic rod 22 is inserted into the inside of the collection chamber 15. The top of the telescopic rod 22 is rotatably connected to two first bearings 23. The outer wall of each first bearing 23 is fixedly connected to an L-shaped plate 24. The inner wall of the collection chamber 15 is fixedly connected to a limit block 26 near the L-shaped plate 24. The L-shaped plate 24 is in movable contact with the limit block 26. The outer wall of the L-shaped plate 24 is provided with a through hole 25.

[0031] The outer wall of the L-shaped plate 24 is rotatably connected to a second bearing 241, and the outer wall of the second bearing 241 is fixedly connected to one end of an elastic rod 242.

[0032] The other end of the elastic rod 242 is fixedly connected to a conical block 243. As the rod descends, the conical block 243 will also press against the debris, causing the debris to be compressed and accumulated. After the L-shaped plate 24 descends, the end of the L-shaped plate 24 contacts the limiting block 26. After the end of the L-shaped plate 24 is compressed, the L-shaped plate 24 rotates through the first bearing 23. During the rotation, the L-shaped corner of the L-shaped plate 24 will move away from the telescopic rod 22. During the movement, the second bearing 241 will move, causing the conical block 243 to press against more positions, causing more debris to be compressed and folded, reducing the area occupied by the debris. After one compression, the telescopic machine 21 will drive the telescopic rod 22 to rise again. The end of the L-shaped plate 24 away from the first bearing 23 will press against the fixed rod 16. Then the L-shaped plate 24 will reset during the rising process. Several arc-shaped blocks 244 are fixedly connected to the bottom of the L-shaped plate 24.

[0033] In use: Place the sheet metal to be pressed onto the lower mold 14. Power on the pressing device 11 and start it. The pressing device 11 drives the upper mold 12 to descend and press the sheet metal. The cutting blade 13 cuts the excess sheet metal on the outer wall of the lower mold 14, causing the excess sheet metal to fall off. The sheet metal debris falls into the collection bin 15 through the through hole 25. Power on the telescopic machine 21 and start it. The telescopic machine 21 drives the telescopic rod 22 to extend and retract. The telescopic rod 22 pulls the L-shaped plate 24 down. The descent of the L-shaped plate 24 squeezes the debris. The first bearing 23 has a torsion spring inside, so the first bearing 23 does not easily rotate. When the L-shaped plate 24 squeezes the debris, it squeezes the larger debris, causing the long strips of debris to be squeezed and folded. The arc-shaped block 244 follows the descent of the L-shaped plate 24 and also squeezes the debris. The cone block 243 descends and presses onto the debris, causing it to fold further and reduce its footprint. As the L-shaped plate 24 descends, its end contacts the limiting block 26. After the end of the L-shaped plate 24 is pressed, the L-shaped plate 24 rotates via the first bearing 23. During this rotation, the L-shaped corner of the L-shaped plate 24 moves away from the telescopic rod 22. This movement causes the second bearing 241 to move, pressing the cone block 243 into more locations and folding the debris in more places, thus reducing its footprint. After one compression, the telescopic machine 21 raises the telescopic rod 22, and the end of the L-shaped plate 24 away from the first bearing 23 presses onto the fixed rod 16. Then, the L-shaped plate 24 returns to its original position during the upward movement.

Finally, the door panel 34 can be opened to remove the debris and dust from the storage chamber 33. After the airflow is filtered by the sponge block 36, it is blown out from the airflow port 35. The airflow port 35 is located on the side of the lower mold 14. When the airflow is blown out, it blows onto the sheet metal after cutting, causing the sheet metal debris adhering to the outer wall of the lower mold 14 to be blown off by the airflow.
