Abstract

The invention discloses a female die assembly of an accurately-positioning bending die for a middle hinge gasket. The female die assembly comprises a lower die seat, a lower base plate, a female die, a jacking block and a spring. The female die is installed above the lower die seat through a fastener. The lower base plate is arranged between the female die and the lower die seat. The middle of the female die is sleeved with the jacking block. The end of the jacking block is in a V shape. The lower end of the jacking block is fixedly connected with the spring, and the lower end of the spring penetrates the lower base plate and is fixedly connected to the lower die seat. The middle of the upper end face of the female die is in a V shape. Two symmetric positioning angle blocks are installed on the female die through screws, and the two positioning angle blocks are in a U shape. According to the bending die, the two positioning angle blocks in the U shape are designed according to the shape of a part to be machined, the accuracy of the pressure center position is ensured, and the forming quality and the size precision of a workpiece are improved.

Description

A kind of middle hinge gasket piece bending die master mold assembly of registration
Technical field
The present invention relates to a kind of mould structure for hinge gasket piece in processing, refer in particular to a kind of bending die master mold assembly of registration.
Background technology
Bending process is the needs according to part shape, by mould and forcing press, blank is curved the Sheet Metal Forming Technology method of certain angle, definite shape workpiece.Attachedly Figure 1 shows that middle hinge gasket piece, this part is typical V-arrangement part, workpiece shapes, relatively simple for structure, and symmetrical, and normally produce in enormous quantities, this part mainly contains Blanking Shaping and bending twice manufacturing procedure.In bending process, need to ensure the bright and clean and no marking of curved rear piece surface, usually be also the important required precision project of bool, but bending die of the prior art more or less can make the surface of bool occur damage in the course of the work, reduces the quality of workpiece; Simultaneously in BENDING PROCESS, also easily occur that pressurized central point offsets, and affects the form and dimensional precision of workpiece.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose the bending die master mold assembly that a kind of machining accuracy is high.
Technical solution of the present invention is achieved in that a kind of middle hinge gasket piece bending die master mold assembly of registration, comprises die shoe, lower bolster, die, kicker, spring; Described die is arranged on the top of die shoe by securing member; Lower bolster is provided with between described die and die shoe; The middle part of described die is arranged with kicker; The top of described kicker is V-shaped; The lower end of described kicker is fixedly connected with spring; The bottom of described spring is fixedly connected on die shoe through lower bolster; The middle part of described die upper surface is V-shaped; Described die is provided with location hornblock by screw; Described location hornblock has symmetrical two pieces.
Preferably, described two location hornblocks are U-shaped, and opening is all just to the center of die.
Preferably, described each location hornblock is also fixed on die 3 by two alignment pins.
Preferably, the shaped portion of described kicker and die is set to 88 °.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The middle hinge gasket piece bending die master mold assembly of registration of the present invention, by installing location hornblock on die, its location hornblock has two pieces, left and right, its Internal periphery designs accordingly according to the profile of workpiece to be processed, workpiece can be placed on die accurately, thus ensure the accurate of centre-of-pressure position, effectively improve forming quality and the dimensional accuracy of workpiece.

Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of middle hinge gasket piece;
Accompanying drawing 2 is master mold modular construction schematic diagram of the present invention;
Accompanying drawing 3 is the plan structure schematic diagram of master mold assembly of the present invention;
Accompanying drawing 4 is the enlarged diagram at A place in Fig. 2;
Wherein: 1, die shoe; 2, lower bolster; 3, die; 4, kicker; 5, spring; 6, screw; 7, hornblock is located; 8, alignment pin; 9, workpiece.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is the finished product structure schematic diagram of the middle hinge gasket piece needing processing, and the angle of its finished work-piece is 90 °.
The middle hinge gasket piece bending die master mold modular construction of registration of the present invention, as shown in accompanying drawing 2 ~ 4, comprises die shoe 1, lower bolster 2, die 3, kicker 4, spring 5; Described die 3 is arranged on the top of die shoe 1 by securing member; Lower bolster 2 is provided with between described die 3 and die shoe 1; The middle part of described die 2 is arranged with kicker 4; The top of described kicker 4 is V-shaped; The lower end of described kicker 4 is fixedly connected with spring 5; The bottom of described spring 5 is fixedly connected on die shoe 1 through lower bolster 2; The middle part of described die 3 upper surface is V-shaped; Described die 3 is provided with location hornblock 7 by screw 6; Described location hornblock 7 has symmetrical two pieces; Two location hornblocks 7, for accurately being located by workpiece to be processed, to guarantee the degree of accuracy of flexural center, can effectively improve component shaping and dimensional accuracy.
Further instruction, described two location hornblocks 7 are U-shaped, and opening is all just to the center of die 3.U-shaped is the corresponding size design made according to the profile of two pieces to be processed, during to guarantee that workpiece to be processed is placed on die 3, and accurate positioning all around.
Further instruction, described each location hornblock 7 is also fixed on die 3 by two alignment pins 8, to guarantee that the position of locating hornblock 7 is not easily subjected to displacement relative to die 3, the accurate location of guaranteeing workpiece to be processed again.
Further instruction, the shaped portion of described kicker and die is set to 88 °, considers the springback angle of workpiece.
The middle hinge gasket piece bending die master mold assembly tool of the registration of the present invention program, its course of work is: mix suitable male molding member and forcing press first to bending die master mold assembly, and installs on the table; The workpiece to be bent 9 of Blanking Shaping is put into die 3, is located by two pieces of location hornblocks 7, workpiece 9 is accurately located.Operationally, male molding member is descending with forcing press for mould, and when after punch and absorption surface, workpiece starts to be bent to absorption surface kicker under the work that presses down of punch, then works Work-sheet pressing at kicker and die one.Forcing press backhaul is up, and male molding member is and then up together, and the workpiece of bending forming is released by kicker under the effect of recoil of spring power, is taken off by finished work-piece, namely completes the bending operation of a workpiece.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
