Type hole upper section and the trailing end outer diameter size of double end lock pin T-type metal connecting piece match, lower section and ceramic insertion core outer diameter phase
Matching；The upper mold is entrenched in middle mould, and lower die is connected with middle mould by the T-type metal connecting piece of double end lock pin, lower die
Bottom end is designed as the structure to match with positioning through hole；The upper mold, middle mould, lower die split size and double end lock pin overall length phase
Deng.
Upper mold described in the utility model is cylindrical structure, and middle mould is circular groove type structure, and lower die is T-type circular platform type knot
Structure；Upper mold in certain the utility model, middle mould, lower die contour structures can also be other shapes（Such as rectangle）As long as can
Realize that above-mentioned dimensional fits and mold match principle.
Crimping formed punch described in the utility model includes the sliding seat connecting with housing slide, and sliding seat is built-in with teeth
Wheel, gear centre are connected with a control handle, and there is pressure head in sliding seat lower end with the design of base center corresponding position is crimped, described
Rack side is fixedly installed with a rack frame, and the gear in the rack gear of rack frame and the sliding seat is intermeshed.
The application method of the utility model is：Referring to Fig. 1, the bottom end of lower die is first put into the positioning through hole of crimping pedestal
In, then middle mould is placed in lower die, the T-type metal connecting piece of double end lock pin is put into middle mould and the through-hole at lower die center,
Then upper mold is put into middle mould, one end ceramic insertion core is fitted into the through-hole at upper mold center, the handle of control crimping formed punch makes
Crimping formed punch compresses downwards, i.e. the crimping of completion one end；Referring to fig. 2, after the completion of the crimping of one end, upper mold, middle mould, lower die are integrally turned over
Turn, is placed in crimping base center, is then fitted into other end ceramic insertion core in the through-hole at lower die center, the hand of control crimping formed punch
Handle compresses crimping formed punch downwards, removes crimp, removes the crimping that upper, middle and lower mould completes a double end ceramic insertion core
Work.
The utility model is simple in sturcture, ingenious in design, the crimping work for needing at least two molds that could complete script
Being integrated into only needs one set of die, reduces lead-time during crimping, while the pressure welding mold for passing through the utility model
Tool is crimped, and double end lock pin overall length and T-type metal connecting piece both ends protrusion length and end face quality all composite qualities require；And
And improve production efficiency and production qualification rate.
