Abstract
The invention discloses a female die assembly of a bending die for a middle hinge gasket. The female die assembly of the bending die for the middle hinge gasket 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 top 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. An antiskid protection layer is arranged on the V-shaped surface of the middle of the upper end face of the female die. 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 female die assembly of the bending die for the middle hinge gasket, during machining in the bending process, a workpiece can be effectively prevented from being scratched, accuracy of the pressure center position is ensured, and the quality of the workpiece is improved.
Description
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 that can complete pad bending operation.
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 hinge gasket piece bending die master mold assembly in one, 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, and the surface of its V-type is provided with abrasionproof protective layer; Described die is provided with location hornblock by screw; Described location hornblock has symmetrical two pieces.
Preferably, described each location hornblock is also fixed on die by two alignment pins.
Preferably, described abrasionproof protective layer thickness is 0.3 ~ 0.5mm.
Preferably, the shaped portion of described kicker and die is set to 87 ° ~ 88 °.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Middle hinge gasket piece bending die master mold assembly of the present invention, be provided with abrasionproof protective layer at die upper surface, carry out in process bending, the problem that workpiece and the violent sliding friction of molding surface form scratch can be solved, effectively avoid abrading workpiece, improve the quality of workpiece; By installing location hornblock on die, workpiece can be placed on die accurately, thus ensure the accurate of centre-of-pressure position, effectively improve shaping and the dimensional accuracy of workpiece.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is the structural representation of the middle hinge gasket piece needing processing, and the knuckle of its finished work-piece is 90 °.
Middle hinge gasket piece bending die master mold modular construction of the present invention, as shown in accompanying drawing 2 ~ 4, comprises master mold assembly, male molding member and guidance set; Described master mold assembly 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, and the surface of its V-type is provided with abrasionproof protective layer 6; Described die 3 is provided with location hornblock 8 by 7 screws; Described location hornblock 8 has symmetrical two pieces, 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 each location hornblock is also fixed on die by two alignment pins, to guarantee that the position of locating hornblock 8 is not easily subjected to displacement relative to die 3, the accurate location of guaranteeing workpiece to be processed again.
Embodiment one: described abrasionproof protective layer 6 thickness is 0.3mm, then the shaped portion of described kicker 4 and die 3 is set to 88 °, considers the springback angle of workpiece.
Embodiment two: described abrasionproof protective layer 6 thickness is 0.5mm, then the shaped portion of described kicker 4 and die 3 is set to 87 °, considers the springback angle of workpiece.
The middle hinge gasket piece bending die master mold assembly tool 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 10 of Blanking Shaping is put into die 3, is located by two pieces of location hornblocks 8, workpiece 10 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.
