Description

Technical Field

[0001] The utility model relates to the technical field of component lead bending dies, in particular to a component lead bending and shearing die. Background Art

[0002] Component leads refer to the conductors that extend outward from the component package. In surface mounted components, they are a general term for external leads such as wing-shaped leads, J-shaped leads, and I-shaped leads. However, the current existing component lead bending process requires multiple positioning and adjustments, which increases the complexity and time-consuming operation. The product needs to be repeatedly positioned during the process, and there are many repeated work sections at multiple stations, which is not conducive to diversified product management and increases production costs. In addition, the process may cause damage to the root of the pin, affecting the consistency of component bending and subsequent mounting operations. Moreover, it cannot be integrated with the shearing process, and cannot guarantee the consistency of the bent and sheared leads of the components and the quality rate of the final finished product. Therefore, in response to the above problems, the present application invents a component lead bending and shearing die, which bends the component into one piece, and integrates the shearing and bending processes, ensuring the consistency of the bent and sheared leads of the components and the quality rate of the final finished product.

The outer side of the upper die pressing block 3 The surface is in sliding and extruding contact with the inner side between the two bending dies 5. Through the setting of the upper die pressing block 3, the components are accurately positioned through the pressing head 202 on the lower die fixed block 2. The press machine 8 is used to press down and drive the bending and shearing foot integrated mechanism 7 to move downward, so that the upper die pressing block 3 in the bending and shearing foot integrated mechanism 7 contacts the component and presses it tightly, thereby achieving the effect of preventing the component from shifting during work. The top of the upper die pressing block 3 is fixedly provided with a compression spring 4. Through the coordinated use of the upper die pressing block 3, the module pressing head 202 and the bending die 5, the component bending process is integrated. The top of the compression spring 4 is in contact with the adhesive The bottom surface of the pressure plate 702 is fixedly connected, and through the setting of the shearing blade 6 and the compression spring 4, a spring transmission is set between the bending die 5 and the shearing blade, so that the shearing blade 6 continues to move downward after the bending die 5 bends the lead, and the excess lead is cut off by the shearing blade 6, thereby achieving the integration of the shearing and bending processes.
