Detailed Description
The present invention is further illustrated by the following examples, which are only a part of the examples of the present invention, and these examples are only for explaining the present invention and do not limit the scope of the present invention.
As shown in fig. 1-2, a voice coil bobbin punching processing device includes a base 1, an outer guide die 2 and an inner guide die 3 are disposed on the base, the outer guide die 2 has a cylindrical inner cavity, and the inner guide die 3 is disposed at an axial center of the outer guide die inner cavity and keeps a certain distance from an inner side wall of the outer guide die 2.
A fixed seat 12 is installed on the inner guide die 3, and a round hole in the center of the fixed seat 12 is used for fixing the voice coil to be processed. The round hole is communicated with the processing groove of the inner guide die 3, and the inner die knife edge positioned on the inner guide die 3 is opposite to the processing groove and used for punching the voice coil.
A plurality of cylinder mounting brackets 5 are provided around the outer guide die 2, and the cylinders 4 of the mounting of the cylinder mounting brackets 5 are provided toward the outer guide die. In the embodiment of the present invention, there are 6 cylinder mounting blocks 5 disposed at regular angular intervals on the periphery of the outer guide mold. The base 1 is provided with a bus bar 10, the bus bar 10 is connected with each cylinder 4, and the cylinders are driven to move through an external pressure regulating valve. The complicated connection structure caused by connecting too many conduits is avoided.
The piston part of the cylinder 4 fixes a punching needle 9 which passes through the punching hole of the outer guide die and the guide die needle sleeve 11 of the inner guide die and faces the axis of the inner guide die 3 and is connected with an inner die knife edge (not shown) of the inner guide die 3.
