Description

Technical Field

[0001] This utility model relates to the field of stamping dies, specifically a precision stamping die device for internal metal components of headphones. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] For example, an automatic precision stamping die as described in (authorization announcement number CN212469484U) includes a stamping die body. A base is provided on the lower outer surface of the stamping die body. A buckle is provided on one outer surface of the base. A lubrication mechanism is provided on the inner surface of the buckle. The lubrication mechanism includes a transparent bottle body, a brush, a connecting rod, and a bottle cap. A compression column and a stamping block are provided on the upper outer surface of the base, and the stamping block is located outside the compression column. A top seat is provided on the upper outer surface of the compression column. A fixing hole and an anti-collision mechanism are provided on the upper outer surface of the top seat, and the anti-collision mechanism is located outside the fixing hole.

[0004] The aforementioned device, through its anti-collision and lubrication mechanisms, can improve the utilization efficiency of stamping dies and their working efficiency. Compared to the aforementioned device, this device, through its dual-camera real-time monitoring system for the die assembly, combined with the motor-threaded rod lifting and positioning mechanism of the material conveying assembly and the electric push rod driven suction cup gripper of the unloading assembly, achieves high-precision closed-loop control of the entire process from stamping to sorting of earphone micro metal parts. This breaks through the bottlenecks of traditional solutions in terms of micro-part damage rate, positioning deviation, and quality traceability, significantly improving production yield and overall equipment efficiency.

An electric push rod 14 is fixedly connected to the upper end of the die base 11. The upper end of the moving die 15 is fixedly connected to the telescopic rod at the lower end of the electric push rod 14, and the lower end of the moving die 15 is slidably connected to the fixed die 12.

[0025] This utility model provides an improved precision stamping die device for internal metal components of headphones, the working principle of which is as follows:

[0026] First, when using this device, place it in the work area and then connect it to an external power source to provide the necessary electrical energy for its operation.

[0027] Secondly, when this device is needed, the electric push rod 14 can be started by the display controller 24 when the raw material is placed on the upper end of the fixed mold 12. After the electric push rod 14 is started, it can drive the moving mold 15 to move downward. When the moving mold 15 moves downward and contacts the fixed mold 12, the raw material can be stamped and formed. At the same time, the first monitoring camera 13 can be started. After the first monitoring camera 13 is started, it can monitor the situation on the upper end of the fixed mold 12 and send the monitored image data to the display controller 24 for processing and display through the data line. This allows the display controller 24 to capture the mold closing state (such as material offset, punch breakage) at the moment of stamping in real time, replacing the traditional manual sampling inspection.

[0028] Example 2:

[0029] Please see Figures 1-4 Compared with Embodiment 1, the precision stamping die device for the internal metal components of the earphone of this utility model further includes: a material conveying assembly 2, a conveyor belt 21 fixedly connected to the front end of the die base 11, a lifting frame 22 fixedly connected to the front end of the conveyor belt 21, a slide rod 23 fixedly connected to the right end inside the lifting frame 22, a display controller 24 fixedly connected to the middle of the front end of the lifting frame 22, a second monitoring camera 25 fixedly connected to the rear side of the upper end of the lifting frame 22, and a motor 26 fixedly connected to the left side of the upper end of the lifting frame 22. After the motor 26 is started, it can drive the threaded rod 27 to rotate. The threaded rod 27 is rotatably connected to the left end inside the lifting frame 22, and the upper end of the threaded rod 27 is fixedly connected to the lower drive shaft of the motor 26.

After the telescopic electric push rod 33 is started, it can drive the telescopic suction cup frame 34 and its upper components to extend and retract. The front end of the telescopic suction cup frame 34 is slidably connected to the hollow groove in the lifting block 31. An electric push rod groove 35 is located at the front end of the telescopic suction cup frame 34. An air supply pipe 36 is fixedly connected to the upper end of the telescopic suction cup frame 34. The upper end of the air supply pipe 36 is fixedly connected to an external air pump. A suction cup 37 is fixedly connected to the lower end of the telescopic suction cup frame 34.

After the telescopic electric push rod 33 is started, it can drive the telescopic suction cup frame 34 to move backward and place the telescopic suction cup frame 34 on the upper end of the fixed mold 12. Then, the motor 26 can be started to drive the threaded rod 27 to rotate and drive the lifting block 31 to move downward so that the telescopic suction cup frame 34 contacts the metal component on the upper end of the fixed mold 12. Then, the external air pump is started to extract the air around the suction cup 37 through the air supply pipe 36 to adsorb the metal component. At the same time, the first monitoring camera 13 and the second monitoring camera 25 can be started to monitor the position of the conveyor belt 21, the telescopic suction cup frame 34 and its upper components, and send the image data to the display via the data cable. The controller 24 processes and displays the data, allowing it to control the real-time position of the telescopic suction cup frame 34 based on image data. When the suction cup 37 adsorbs the metal component on the upper end of the fixed mold 12, the controller can start the motor 26 and the telescopic electric push rod 33 to allow the metal component to be transported and placed on the upper end of the conveyor belt 21. Then, the controller can start the vacuum pump to allow the metal component to be placed on the upper end of the conveyor belt 21. At the same time, the controller can start the conveyor belt 21 to transport the metal component to complete the unloading. Then, the metal material can be placed on the upper end of the conveyor belt 21 and transported to the lower end of the telescopic suction cup frame 34. The controller can detect the position of the metal material based on image data and automatically load the metal material onto the upper end of the fixed mold 12 through the telescopic suction cup frame 34 and its upper components.

[0033] This utility model improves the precision stamping die device for internal metal components of headphones. By setting up a dual-camera real-time monitoring system for the die assembly 1, combined with the lifting and positioning mechanism of the motor 26-threaded rod 27 in the feeding assembly 2 and the electric push rod driven suction cup 37 gripper in the unloading assembly 3, it achieves high-precision closed-loop control of the entire process from stamping to sorting of micro metal parts for headphones. It breaks through the bottlenecks of traditional solutions in terms of micro-part damage rate, positioning deviation and quality traceability, and significantly improves production yield and overall equipment efficiency.
