Dynamic movable core rod, the width of the movable core rod is A, and length is B, and the distance between the guide plate of the left and right sides is D, front and rear
Distance is to be provided with compression rebound mechanism below d, the A=D, B=d, the movable core rod between the guide plate of both sides；It is described convex
The stamping surface of mould is square planar, and the width of the square planar is E, and length is F, the E=A-H.
The compression rebound mechanism includes being provided with some be available on the die shoe below some locating dowels, the locating dowel
Spring is set with the positioning hole that locating dowel enters, the locating dowel between the movable core rod and die shoe.
Connected between the cope plate and die shoe by telescopic guide rod, the guide rod includes guide pin bushing and guide pillar.
Outer surface width after the workpiece punch forming to be punched is W, and length is L, and the A=D=W, B and F are more than
Or equal to L.
It is bolted between the punch-pin and cope plate.
Buffer stopper is provided with die shoe below the movable core rod.
The beneficial effect that the present invention is reached：
Punch-pin and movable matrix cooperate, and realize the backfin to workpiece side to be processed, metal plate is formed U-shaped knot
Structure；Movable matrix includes guide plate and movable core rod, and movable core rod extrudes compression rebound mechanism in punching press and moved down, to be added
The workpiece of work enters in cavity plate under punch-pin punching press, bends side；After the completion of punching press, cope plate drives punch-pin to moving up
Dynamic, movable core rod is moved up under the screen resilience effect of compression rebound mechanism, and the workpiece after punching press is ejected in matrix cavity, made
It is easy to take out；Needing that ejecting mechanism is installed below cavity plate existing die mechanism more, so as to after punching press by cavity plate
Workpiece takes out, and the present invention need not install extra ejecting mechanism, is realized and is directly taken after processing using the mechanism of cavity plate in itself
Part.
Therefore, a kind of U-shaped computer cover plate processing mold provided by the present invention, can be achieved the flanging of metal plate, and
It is easy to pickup, it is easy to use, it is simple in construction.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Schematic diagram when Fig. 2 is punching press of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
A kind of U-shaped computer cover plate processing mold as illustrated in fig. 1 and 2, including cope plate 1 and die shoe 2, the die shoe
Movable matrix is provided with 2, the lower section of cope plate 1 is provided with punch-pin 3, and thickness is positioned over activity for H workpiece to be punched
Between cavity plate and punch-pin 3, the movable matrix includes the guide plate 4 of side, and the activity that can be moved up and down between guide plate 4
Core rod 5, the width of the movable core rod 5 is A, and length is B, and the distance between the guide plate 4 of the left and right sides is D, front and rear sides
Guide plate 4 between distance be d, the A=D, B=d, the lower section of movable core rod 5 is provided with compression rebound mechanism；The punch-pin
3 stamping surface is square planar, and the width of the square planar is E, and length is F, the E=A-H.
The compression rebound mechanism includes being provided with some locating dowels 6, the die shoe 2 of the lower section of the locating dowel 6 some
Spring 8, institute are set with the positioning hole 7 for being available for locating dowel 6 to enter, the locating dowel 6 between the movable core rod 5 and die shoe 2
State locating dowel 6 with positioning hole 7 to coordinate, movable core rod 5 is stably moved up and down, spring 8 enables movable core rod 5 in punching
