The Chinese utility model 'punch quick-changing device' (publication number: CN206122487U) discloses a die punch, in particular a punch quick-changing device, which comprises a punch mounting plate, a shoulder-shaped punch seat, a punch and a pressure plate; the shoulder-shaped punch seat is fixed on the punch mounting plate, the pressure plate is positioned below the punch mounting plate, and the punch is positioned in a hole of the pressure plate; the bottom of the shoulder-shaped punch head seat is provided with a punch head groove, the top of the punch head is provided with a punch head bulge, the punch head bulge is inserted into the punch head groove, and the punch head is fixed on the shoulder-shaped punch head seat through a screw. Although the utility model provides a drift quick replacement device can shorten retooling time, nevertheless it with the utility model discloses a structure exists the difference.
Disclosure of Invention
The utility model aims at the not enough of above-mentioned prior art, provide a stamping die drift quick change device, realize mould drift quick detach, quick change.
For solving the above technical problem, the utility model discloses a technical scheme is:
a punching head quick-change device of a punching die comprises a pressing device, a striking rod and a punching head, wherein the striking rod is arranged between the pressing device and the punching head and is independently arranged;
the upper end and the lower end of the knock-out rod are both provided with first internal threaded holes;
and a second internal threaded hole is formed in the contact end of the punch and the striking rod.
The compressing device is a screw plug.
The screw plugs are arranged in two numbers and are coaxially arranged.
The first internally threaded hole and the second internally threaded hole are arranged equivalently.
The striking rod is made of 45# steel.
The utility model has the advantages that:
1) the quick-change device for the punch of the stamping die can be used on a plurality of stamping die repairing machines by arranging the pressing device, the striking rod and the punch, and compared with the mode of removing the die and changing the punch, the quick-change device for the punch of the stamping die has the advantages that the working time is effectively shortened, the labor intensity is reduced, and the process steps are reduced;
2) the double screw plugs are arranged, so that the self-locking and anti-loosening effects can be achieved, and the smooth operation of the punching process is ensured;
3) in the use, need not special device, one alone one set of spanner can be operated, and the operability is good, and is efficient.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an assembly view of the present invention and the upper die base.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
The utility model provides a quick change device for a punch of a stamping die, which is shown in figure 1 and figure 2.
This stamping die drift quick change device, including closing device, play pole 2 and drift 3, and play pole 2 arranges in between closing device and the drift 3, and the three sets up independently.
In the embodiment, the compression device is a screw plug 1, and the screw plug 1 adopts a standard component, has an external thread structure and is provided with an internal hexagonal wrench locking counter bore; preferably, the two screw plugs 1 are coaxially arranged to achieve a self-locking function.
The upper end and the lower end of the striking rod 2 are both provided with first internal threaded holes 21, and the striking rod is made of 45# steel; and a second internal threaded hole 31 is formed in the contact end of the punch 3 and the striking rod 2. In this embodiment, the first internally threaded hole 21 and the second internally threaded hole 31 are equally arranged for faster disassembly.
During punching operation, install this punching die drift quick change device in upper die base 4, can see specifically that fig. 2 shows, at first the drift 3 of impressing, secondly put into the knockout pin 2, put into the plug screw 1 at last, plug screw 1 leans on outer thread structure and upper die base 4 fastening connection, screw up two plug screws 1 through the spanner, make it and knockout pin 2 direct contact, and prop up drift 3 with knockout pin 2 downwards, compress tightly drift 3 on drift splint 5, make drift 3 fixed, whole mechanism of punching a hole is provided by two pieces of plug screws 1 in the direction atress that punches a hole, two pieces of plug screws 1 can play fastening, locking effect simultaneously, ensure to punch a hole the smooth realization of technology.
When the punch needs to be removed or replaced, the screw plug 1 is loosened by a wrench, and then the bolt is screwed into the first internal thread hole 21 of the knock-out rod 2 and taken out upwards; subsequently, the bolt is screwed into the second inner threaded hole 31 of the punch 3 and is upwards taken out, so that the punch 3 is quickly disassembled and quickly replaced, the punch quick-replacing device of the stamping die is simple and quick to operate, time and labor are saved for workers to operate, and the efficiency of punch replacement can be improved to a greater degree in the production process.
