Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the one-step forming conductive needle processing mold of the present invention comprises a mold body 11, one side of the mold body 11 is provided with a stepped hole structure, the stepped hole is sequentially provided with an insertion hole 12, a forming hole 13 and a spring hole 14 from outside to inside, a buffer spring 15 is arranged in the stepped hole, and one end of the buffer spring 15 is supported in the spring hole 14; a notching 16 is further provided on one side of the insertion hole 12, and the notching 16 has a depth greater than that of the insertion hole 12.
The die is used for processing the conductive needle, the processed conductive needle finished product is shown in figure 3 and comprises a needle rod 1, the needle rod 1 is of a cylindrical structure, a circular truncated cone structure 2 is arranged on the needle rod 1, the side edge of the circular truncated cone structure 2 is provided with a plane notch structure 6, an anti-skid texture structure 3 is arranged on the rear side surface of the circular truncated cone structure 2, and the anti-skid texture structure 3 can prevent the conductive needle from rotating relative to a shell assembled with the conductive needle.
During processing, the rear end of the needle rod 1 is clamped by an external cylindrical clamping component, the cylindrical clamping component can be a double-arc-shaped clamping plate and the like, the cylindrical clamping component drives the needle rod 1 to enter a die from an insertion hole 12, the diameter of the insertion hole 12 is larger than that of the needle rod 1, and the diameter of the forming hole 13 is slightly smaller than that of the needle rod 1; in the entering process of the needle bar 1, the front end part of the needle bar can prop against the buffer spring 15, the buffer spring 15 plays a buffer role and generates certain thrust when the needle bar 1 exits; after the clamping component carries the needle bar 1 to enter the forming hole 13, the material of the outer circumference of the front end of the needle bar 1 is extruded and is gathered between the inner edge of the insertion hole 12 and the clamping component, and finally, a circular truncated cone structure 2 is formed on the needle bar 1; the front end of the clamping part is provided with an embossing structure with anti-skid grains, and the rear side of the circular truncated cone is naturally extruded with the anti-skid grain structure 3 when the circular truncated cone structure 2 is formed; the molding hole 13 and the spring hole 14 are in smooth transition through a conical surface, and the front end of the needle rod 1 is extruded by the conical surface to naturally form a corresponding conical surface structure.
After the extrusion processing is finished, the punch cutter enters the punching groove 16, and a part of the circular truncated cone structure inserted into the hole 12 is punched out, so that a plane notch structure 6 can be formed; after the extrusion processing is finished, a positioning part 4 and a threading hole 5 are processed at the rear end of the needle bar 1 by subsequent procedures.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
