In figure: 1, patrix; 11, upper bolster; 12, patrix upper padding plate; 13, upper mold holder; 14, upper molded plate; 15, patrix is got drift ready; 2, counterdie; 21, die shoe; 22, counterdie backboard; 23, counterdie backing plate; 24, counterdie carbon air spring; 25, get module 25 ready; 3, patrix carbon air spring.
The specific embodiment:
Embodiment: see Fig. 3, shown in 4, automobile safety belt retractor raising point mould, comprise patrix 1 and counterdie 2, patrix 1 is by upper bolster 11, patrix upper padding plate 12, upper mold holder 13 and upper molded plate 14 form, at least three patrix carbon air springs 3 are fixed on upper bolster 11, together with the piston rod of patrix carbon air spring 3 is bolted on upper molded plate 14, together with patrix upper padding plate 12 is fixed by screws in upper mold holder 13, the piston rod sleeve of patrix carbon air spring 3 is in the default hole of patrix upper padding plate 12 and upper mold holder 13, patrix is got drift 15 ready and is fixed in mould upper padding plate 12 and upper mold holder 13, the front end that patrix is got drift 15 ready is dome shape, on upper molded plate 14, form patrix and get drift 15 ready through hole 151 and material strip coiler blank accepting hole 152,
Material strip B is placed between patrix 1 and counterdie 2, counterdie 2 is by die shoe 21, counterdie backboard 22 and counterdie backing plate 23 form, counterdie backboard 22 and counterdie backing plate 23 are fixed by screws on die shoe 21, counterdie carbon air spring 24 is fixed on die shoe 21, the piston rod of counterdie carbon air spring 24 passes the default hole on counterdie backboard 22 and counterdie backing plate 23 and exposes from the upper surface of counterdie backing plate 23, getting module 25 ready is placed in counterdie backing plate 23 and is fixed together by screw and counterdie backboard 22, get module 25 ready and form several shrinkage pools 251, it is relative one by one that several shrinkage pools 251 and several moulds are got drift 15 ready.
Described patrix carbon air spring 3 has four, and counterdie carbon air spring 24 has four.
Described material strip coiler blank accepting hole 152 has the shape matching with material strip coiler blank.
The front end that described patrix is got drift 15 ready is frustum of a cone column.
The front end that described patrix is got drift 15 ready is nipple-like.
Described four counterdie carbon air springs 24 are separately positioned on four angles of square counterdie backboard 22.
The described module 25 of getting ready has the upper surface shape identical with the base plate of blank on material strip B.
Described compression leg 16 be fixed on patrix upper padding plate 12 and sleeve in upper mold holder 13, compression leg 16 exposes the lower surface of upper mold holder 13.
Operation principle: material strip B is placed between patrix 1 and counterdie 2, upper bolster 11 is to be fixed on the drift of punch press, upper bolster 11 moves downward when punching press, first patrix carbon air spring 3 allows upper molded plate 14 contact with material strip B in top downwards upper molded plate 14, material strip B is shifted onto on the piston rod of counterdie backing plate 23 and counterdie carbon air spring 24, simultaneously patrix is got drift 15 ready and is moved downward and get several shrinkage pools 251 in module 25 ready and be engaged on material strip B and stamp out salient point again.It is in punching course, and the motion of getting drift 15 due to patrix ready will overcome 3 elastic resistances of patrix carbon air spring, so when patrix is got drift 15 ready and is punched in material strip B, have a shorter buffer time, can protect like this salient point A1 smooth surface of being up to.
Because the piston rod of counterdie carbon air spring 24 is crushed under material strip B, when patrix rises, the piston rod of mould carbon air spring 24 just can, by the demoulding of material strip B jack-up, facilitate material strip B to carry to lower one mould of the progressive die.
