Description

Technical Field

[0001] This utility model relates to the field of auxiliary blanking technology for stamping parts, and in particular to a stamping air blowing device for small sheet metal parts. Background Technology

[0002] Stamping is a processing technology that uses a mold to apply pressure to metal sheets to rapidly form them. By placing a metal sheet on a special mold, complex parts such as car shells and home appliance panels can be produced in seconds. It is both precise and efficient. This process is widely used in the manufacturing industry and can mass-produce various thin-shell parts. It is an indispensable production method in modern industrial assembly lines.

[0003] During the stamping process, sheet metal needs to be stamped to form bent structural parts. To ensure safety, after the stamping machine completes one stamping of the sheet metal, the worker will use a rod with a magnet at one end to attract and remove the stamped part directly below the stamping machine. Although this method greatly ensures the safety of the worker, it is only effective for magnetic parts, and the worker needs to spend extra time removing the part attracted to the rod. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stamping air blowing device for small sheet metal parts. It solves the problems of limitations and inconvenience in the existing technology when using magnetic components to remove parts from under the impact machine for worker safety during the stamping process.

[0005] According to an embodiment of this utility model, a stamping air blowing device for small plates includes a fixing member, a support rod, and a hose.

One end of the support rod is rotatably connected to the top of the fixing member through a rotating table. The fixing member is provided with a limiting member to restrict the rotation of the rotating table. A connecting rod is provided at the other end of the support rod. A connecting platform is provided at the end of the connecting rod away from the support rod. A connecting cylinder is fixedly provided on the connecting platform. One end of the hose passes through the connecting cylinder. A locking member is also connected to the connecting cylinder to lock the hose and the connecting cylinder together.

[0006] Compared with the prior art, this utility model has the following beneficial effects: By installing this device on the machine base of the stamping machine and pointing the spray direction of the device's hose toward the mold, after the stamping machine punches and bends the sheet metal, the stamping head of the stamping machine lifts up, and the sheet metal will slightly rebound due to the release of elasticity. After being slightly attracted by the stamping head, it falls onto the top of the mold. During this process, the high-pressure gas sprayed from the hose blows the bent sheet metal to a position away from it, realizing the function of unloading the bent sheet metal from the mold. It can be used for unloading different materials from the mold, has a wide range of applications, and at the same time reduces the labor intensity of workers and ensures the safety of workers.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 4As shown in the figure, this utility model embodiment proposes a stamping air blowing device for small plates, including a fixing member, a support rod 5, and a hose 6. The fixing member is used to fix it to the worktable of the stamping machine. The fixing member includes: a concave block 1, a screw 2 threadedly connected to the concave block 1, one end of the screw 2 extending into the groove of the concave block 1 and having a clamping block 3, and a handle 4 fixedly fixed to the other end of the screw 2. One end of the support rod 5 is rotatably connected to the top of the fixing member through a rotating platform 7. The fixing member has a limiting member to restrict the rotation of the rotating platform 7. The other end of the support rod 5 has a connecting rod 8. The end of the connecting rod 8 away from the support rod 5 has a connecting platform 9. A connecting cylinder 10 is fixedly fixed on the connecting platform 9. One end of the hose 6 passes through the connecting cylinder 10. A locking member is also connected to the connecting cylinder 10 to lock the hose 6 and the connecting cylinder 10 together. The rotating platform 7 is rotatably connected to the top of the concave block 1, and the rotating platform 7 is fixedly connected to the support rod 5. When installing this device, it is fixed to the machine platform of the stamping machine by the fixing component. In the fixed type, the groove of the concave block 1 is stuck in the machine platform of the stamping machine. Then, the handle 4 is turned, which drives the screw 2 to rotate, so that the screw 2 is screwed into the groove of the concave block 1, so that the clamping block 3 at the end of the screw 2 abuts against the machine platform of the stamping machine, so that the device is clamped and fixed on the machine platform of the stamping machine. Then, the support rod 5 is rotated so that the connecting cylinder 10 faces the mold on the stamping machine. The rotating platform 7 is fixed by the limiting component. One end of the hose 6 is inserted into the connecting cylinder 10 and locked by the locking component. The other end of the hose 6 is connected to the external high-pressure air pump so that the hose 6 can spray high-pressure airflow when needed. During operation, the press presses down onto the die, bending the sheet metal placed on the die. After one pressing action, due to the compression of the inner layer and tension of the outer layer during bending, when the press head lifts, the sheet metal will slightly rebound due to elastic release. It will be slightly attracted by the press head and fall onto the top of the die. During the process of the bent sheet metal falling onto the die, the high-pressure air pump is activated. The high-pressure air pump sprays high-pressure gas through hose 6. The high-pressure gas blows the bent workpiece to the side away from it on the machine platform. The device features an inclined plate with side panels. The bent sheet metal falls onto the inclined plate and is positioned at a predetermined location. It's worth noting that a solenoid valve or pneumatic valve can be used to control the high-pressure air pump's valve opening and closing via electrical or pneumatic signals. This allows high-pressure gas to be released from the hose 6 only when needed. Specifically, the valve can be opened via a foot pedal or linked to the stamping machine via a PLC programmable logic controller. The high-pressure air pump's valve opens during the lifting process after the stamping machine completes one stamping operation, performing a blowing operation. With this device, after the sheet metal is stamped and bent by the stamping machine, the high-pressure gas ejected from the hose 6 blows the bent sheet metal to a position away from it, effectively unloading the bent sheet metal from the mold. This device is suitable for a wide range of sheet metal materials, reducing the time workers spend retrieving materials from the mold, improving production efficiency, reducing labor intensity, and ensuring worker safety.As a similar embodiment, the fixing element can be a magnetic base.

[0021] like Figures 1 to 2 As shown, the locking component further includes: a locking sleeve 11, a connecting tube at one end of the locking sleeve 11, an external thread 12 on the connecting tube, a plurality of elastic clips 13 at equal intervals at the end of the connecting tube away from the locking sleeve 11, an internal thread adapted to the external thread 12 at the end of the connecting tube facing the locking sleeve 11, and the inner diameter of the connecting tube 10 gradually decreasing along the direction away from the connecting tube. Specifically, the inner diameter of the connecting cylinder 10 includes a threaded section and a constricted section. The threaded section is located at the end of the connecting cylinder 10, and the constricted section is connected to the threaded section. The constricted section is a section where the inner diameter of the connecting cylinder 10 gradually decreases. When the hose 6 is locked and fixed on the connecting cylinder 10, the hose 6 is passed through the locking sleeve 11 and the connecting cylinder 10 in sequence, and one end of the hose 6 extends out of the connecting cylinder 10. Then, the locking sleeve 11 is rotated, and the locking sleeve 11 is screwed onto the connecting cylinder 10 through the external thread 12 on the connecting pipe. During the process of the connecting pipe being screwed into the connecting cylinder 10, the elastic clamp 13 is limited by the constricted section and gradually moves towards the axis of the connecting cylinder 10, thereby clamping the hose 6, restricting the movement of the hose 6, ensuring the stability of the hose 6 when spraying high-pressure gas, and preventing the hose 6 from swinging arbitrarily after being subjected to reaction force.

[0022] like Figures 3 to 4 As shown, the limiting component further includes a spring 14, and the top of the fixing component has a mounting groove. A column 15 is slidably mounted in the mounting groove. A pin 16 is provided at one end of the column 15 facing the rotating platform 7. One end of the spring 14 is fixedly connected to the column 15, and the other end of the spring 14 is fixedly connected to the side of the mounting groove away from the rotating platform 7. The rotating platform 7 has several insertion holes for the pin 16 to be inserted. The column 15 moves towards the rotating platform 7 under the push of the spring 14, and the pin 16 is inserted into the insertion hole on the rotating platform 7, thereby restricting the rotation of the rotating platform 7. When it is necessary to adjust the blowing direction of this device, the column 15 is pulled towards the spring 14 to overcome the elastic force of the spring 14, so that the pin 16 is dislodged from the insertion hole. At this time, the rotating platform 7 can be adjusted arbitrarily to change the blowing direction of this device (the orientation of the connecting cylinder 10). Finally, the pin 16 is reinserted into the insertion hole.

[0023] like Figure 5As shown, in another embodiment, the limiting component includes: a spring 14; a mounting groove is provided on the top of the fixing component; a column 15 is slidably disposed in the mounting groove; one end of the spring 14 is fixedly connected to the column 15; the other end of the spring 14 is fixedly connected to the mounting groove on the side away from the rotating platform 7; a rubber ring 17 is sleeved on the circumferential outer wall of the rotating platform 7; and a first rubber pad 18 is provided on the end of the column 15 facing the rotating platform 7. In another embodiment, when adjusting the blowing direction of the device, pulling the column 15 causes it to move away from the rotating platform 7, separating the first rubber pad 18 from the rubber ring 17. At this time, the rotating platform 7 can be adjusted arbitrarily. After the blowing direction of the device is adjusted, the column 15 is released, and the column 15 moves towards the rotating platform 7 under the push of the spring 14. At this time, the first rubber pad 18 abuts against the rubber ring 17, and the friction between them restricts the rotation of the rotating platform 7.

[0024] Furthermore, the clamping block 3 is rotatably connected to the screw 2. When the screw 2 rotates and screws into the groove of the concave block 1, because the screw 2 and the clamping block 3 rotate, when the clamping block 3 comes into contact with the press machine platform, the clamping block 3 and the machine platform do not rotate. The screw 2 continues to rotate to make the clamping block 3 fit even tighter, preventing the device from coming loose from the machine platform.

[0025] like Figure 1 and Figure 3 As shown, furthermore, a second rubber pad 19 is provided on the side of the clamping block 3 away from the screw 2. The second rubber pad 19 can increase the friction between the clamping block 3 and the machine tool.

[0026] Furthermore, the support rod 5 is a telescopic rod. Specifically, the telescopic rod can be a tubular telescopic rod, which can be lengthened or shortened to adapt to molds of different heights, thereby increasing the applicability of this device.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
