Steel ball, the both ends of the spring bear against the plug, steel ball, and the side wall of the punch is equipped with arc groove, the punch
Punch installation trench bottom is inserted into, the steel ball is against the bottom inflection point of the arc groove.
Further, the diameter of the through-hole is less than the diameter of steel ball, and the part that the steel ball exposes to through-hole is corresponding
Action is more than the corresponding depth of bottom inflection point of the arc groove.
Further, the mold includes lower die, and the lower die includes die holder, buoyant plate and punch, the buoyant plate
Floating mount on the die holder and passing through guiding mechanism and the die holder and be oriented to and coordinate, the punch be set to it is described under
The copper guide sleeve coordinated with the punch is installed on die holder and in the buoyant plate, the buoyant plate；The guiding mechanism
Including guide plate and guide holder, the guide holder is equipped with a pair of and is divided into the buoyant plate both sides, the guide holder with it is described
Die holder is fixedly connected, and the guide plate includes interior guide plate and outer guide plate, and the buoyant plate is opposite with the guide holder
One side end face is fixed with outer guide plate, and a guide holder side end face opposite with the buoyant plate is fixed with interior guide plate, institute
Outer guide plate is stated to be bonded to each other and be slidably matched with the interior guide plate.
Further, it positions and is fastened by bolts by flat key between the guide holder and the die holder.
Further, the interior guide plate and the outer guide plate are wearing plate.
During the die change punch that the utility model leads to, thimble is inserted into from centre hole, and steel ball is pushed, and releases steel ball pair
The limiting of punch, so as to take out punch；Punch after replacement, steel ball limit punch against at arc-shaped groove bottom inflection point
Position is fixed；The structure is dismantled without counterweight header fixed seat, is installed, is positioned so that the replacement operation of punch is simpler just
It is prompt.

Specific embodiment
The mold for being capable of quick-replaceable punch of the utility model, as shown in Figure 1 and Figure 2, consolidates including punch 6 and punch
Reservation 13, punch fixed seat 13 are fixed in lower die, punch fixed seat 13 offer punch mounting groove 14, steel ball mounting groove 15 with
And the centre hole 22 that steel ball mounting groove 15 connects, steel ball mounting groove 15 are obliquely installed relative to punch mounting groove 14 and connect steel ball
Mounting groove 15, the lower end of steel ball mounting groove 15 are encapsulated by plug 19, and spring 18 and steel ball 17 are equipped in steel ball mounting groove,
The both ends of spring 18 bear against plug 19, steel ball, and the side wall of punch 6 is equipped with arc groove, and punch 6 is inserted into punch mounting groove
14, bottom, steel ball is against the bottom inflection point of arc groove, it is preferable that the diameter of through-hole is less than the diameter of steel ball, and steel ball exposes to
The action of the part of through-hole is more than the depth of bottom inflection point 22.When replacing punch, thimble is inserted into from centre hole, will be under steel ball
Pressure releases limiting of the steel ball to punch, so as to take out punch；Punch after replacement, steel ball against at arc-shaped groove bottom inflection point,
And then punch is limited and is fixed；The structure so that the replacement of punch, positioning action are simpler convenient.
The upper mold of the mold includes upper mold seat 1 and profiled sheeting 3, and profiled sheeting 3 is installed on by being molded backing plate 2 under upper mold seat 1,
Its lower die include die holder 5, buoyant plate 4 and punch 6,4 floating mount of buoyant plate on die holder 5 and pass through guiding mechanism under
Die holder 5 is oriented to cooperation, and punch 6 is set on die holder 5 and is equipped with what is coordinated with punch 6 in buoyant plate 4, buoyant plate 4
Copper guide sleeve 7；Guiding mechanism includes guide plate and guide holder 10, and guide holder 10 is equipped with a pair of and is divided into 4 both sides of buoyant plate, is oriented to
Seat 10 is fixedly connected with die holder 5, and guide plate includes interior guide plate 9 and outer guide plate 8, and buoyant plate 4 is opposite with guide holder 10
One side end face is fixed with outer guide plate 8, and the side end face opposite with buoyant plate 4 of guide holder 10 is fixed with interior guide plate 9, outer guiding
Plate 8 is bonded to each other and is slidably matched with interior guide plate 9.By setting the copper guide sleeve coordinated with punch, Neng Gouyou on buoyant plate
Effect reduces effect of the lateral force to punch, makes shaping column longer life expectancy, while copper guide sleeve also is able to improve punching precision；Buoyant plate
It is oriented to by guide holder, inside and outside guide plate cooperation between die holder, there is better mechanical strength, prevent in lateral force
Effect occurs to be oriented to deformation, flitch buoyance lift is avoided to shift, it is ensured that subsequent process punching precision.
It positions and is fastened by bolts by flat key between guide holder 10 and die holder 5, as shown in Figure 1,11 pacify for bolt
Hole is filled, 12 be flat key mounting hole；Interior guide plate 9 and outer guide plate 8 are wearing plate, have better service life.
