Description

Technical Field

[0001] The utility model belongs to the technical field of stamping devices, and particularly relates to a punching device for conductive cloth tape with automatic slag discharge. Background Art

[0002] When electronic products are in use, they will release electromagnetic waves, causing electromagnetic interference among other surrounding electronic devices and resulting in abnormal operation. Therefore, in order to achieve electromagnetic shielding and static electricity conduction, conductive cloth tapes are usually provided on the circuit boards of electronic product lines. At the same time, the screws and columns provided on the circuit boards of electronic product lines need to be avoided. Generally, a stamping device is used to process the avoidance holes of the conductive cloth tape. However, since the conductive cloth tape is made of conductive cloth and is thin and sticky, the waste material from each stamping of the avoidance hole will stick to the punch head. When a certain thickness of conductive cloth tape adheres to the punch head, it will affect the stamping effect of the stamping device. As a result, the stamping device needs to be shut down, and the waste conductive cloth tape on the punch head needs to be manually removed. This method affects the stamping forming of the avoidance holes on the conductive cloth tape, is time-consuming and laborious, thus reducing the work efficiency. Moreover, the waste materials are scattered everywhere, which is not convenient for collection and treatment and affects the working environment. Summary of the Invention

Specific Embodiments Specific Embodiment 1:

[0024] Refer to Figures 1 to 3As shown in the figure, an automatic slag-discharging punching device for conductive cloth tape includes a stamping device 1. The stamping device uses an existing stamping die and is provided with an upper template 2, a lower template 3, a punch 4, etc. A guiding column 5 is arranged between the upper template 2 and the lower template 3. The punch 4 is arranged on the upper template 2, and a convex film 6 is arranged on the lower template 3. A punching hole 4-1 is formed on the lower end face of the punch 4, and the punching hole 4-1 is located in the middle of the punch 4, so that the conductive cloth tape to be processed is uniformly stressed, ensuring the punching quality. The punching hole 4-1 is a round hole or a rectangular hole, and the punching hole 4-1 is determined according to the shape and size of the punching required for the conductive cloth tape. The punching hole 4-1 of the punch 4 cooperates with the convex film 6 of the lower template 3, so that the upper film drives the punch to move downward to cooperate with the convex film of the lower template, and a relief hole is punched on the conductive cloth tape. A slag-discharging groove 4-2 is formed at the upper end of the punch 4. The slag-discharging groove 4-2 is a rectangular groove, and discharge ports are formed on two opposite sides of the slag-discharging groove 4-2. The slag-discharging groove 4-2 is communicated with the punching hole 4-1 to form a waste stacking space. The waste generated by punching enters the waste stacking space through the punching hole. When the waste accumulates and fills the slag-discharging groove, the waste is pushed from one discharge port to the other discharge port, so that the waste is extruded from the other side, realizing automatic stacking and discharging of waste.

[0025] The punching hole 4-1 is a stepped hole with a gradually increasing diameter from bottom to top. This stepped hole facilitates the automatic upward stacking movement of the waste generated during the stamping of the punch through the punching hole, effectively avoiding material jamming.
