Description
Technical field
It the utility model is related to a kind of big arm support deburring stamping die of windshield wiper.
Background technology
Windshield wiper large arm dimensional accuracy is high, complicated, there is multiple torsions in forming process, centre installation plastic part
Square hole requires Glabrous thorn；Due to rain brush large arm irregular structure, needed in forming process by distorting complicated molding die
Punch forming, the burr installed in square hole influences molding effect, poor product quality, and the common progressive die can not realize feeding；
Traditional Sheet Metal Forming Technology is had using multiple tracks single die, and burr larger in square hole is installed after punching press and is gone by subsequent artefacts' polishing
Remove, low production efficiency, high processing costs.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind and can be used on continuous producing apparatus, and energy
The big arm support deburring stamping die of windshield wiper of enough automatically removing burr moulds.
The big arm support deburring stamping die of windshield wiper of the utility model, including suitable for continuous production Wiring technology
Overall mould bases, Burr removal mold is set on overall mould bases in front of molding die, and Burr removal mold includes upper die and lower die, on
Mould bottom, lower die tip coordinate crimping in workpiece square hole, it is characterised in that：Surrounding has cutting inclined-plane, surrounding at the top of lower die
Cutting inclined-plane form trapezium structure；The shape that cutting inclined-plane surrounds is adapted with workpiece square hole shape；Cut inclined-plane base with
Lower die side is smoothly transitted connection by circular arc；
The transition arc on the cutting inclined-plane is adapted with workpiece lumen circular arc；
The lower die top surface is the less arc-shaped curved surface of radian；
The upper mold bottom surface has the curved surface being adapted with lower die top surface.
The big arm support deburring stamping die of windshield wiper of the utility model, by coordinating at the top of lower die with upper mold bottom
Crimping, installation square hole punching press excision installation square hole edge is upward through by the cutting inclined-plane of surrounding at the top of lower die from workpiece lumen
Burr, can be used on continuous producing apparatus, and can automatically removing burr mould, without subsequent artefacts polish, size essence
Degree is high, and product quality is stablized, and production efficiency is high, and production cost is low.

Embodiment
As shown in the figure, a kind of big arm support deburring stamping die of windshield wiper, including suitable for continuous production Wiring technology
Overall mould bases 1,7, Burr removal mold is set in front of molding die on overall mould bases 1,7, and Burr removal mold includes upper mold
14th, lower die 11, upper mold 14 are fixedly connected in the overall top mold frame 1 of tinuous production and can move up and down with overall top mold frame 1,
14 bottom of upper mold has the upper mold core that can extend into windshield wiper large arm stent workpiece installation square hole；Lower die 11 is fixedly connected on
On the overall undercarriage 7 of tinuous production simultaneously, the top of lower die 11 has is adapted with windshield wiper large arm stent workpiece cavity shape
Raised core rod, can extend at the top of raised core rod in windshield wiper large arm stent workpiece installation square hole with 14 bottom of upper mold
Core rod coordinates crimping；
11 top surrounding of lower die has cutting inclined-plane 21, and the cutting inclined-plane 21 of surrounding forms trapezium structure；Cut inclined-plane 21
Stretched at the top of lower die 11 in windshield wiper large arm stent workpiece installation square hole and pass through punching press when coordinating and crimp with 14 bottom of upper mold
The direct punching of shearing force removes the burr of installation square hole inward flange so that workpiece square hole inner side edge bottom is formed and the top of lower die 11
The inclined-plane that trapezium structure is adapted, larger burr is removed by 11 top trapezium structure punching press of lower die in workpiece square hole, it is impossible to is gone
That removes flattens the inclined-plane for being formed and being adapted with 11 top trapezium structure of lower die, structure letter by 11 top trapezium structure impact extrusion of lower die
It is single, it is easy to operate, without subsequent artefacts' polishing operation；The shape and workpiece square hole shape at the top of lower die 11 that cutting inclined-plane surrounds
It is adapted, the top of lower die 11 can be smoothly stretched into workpiece square hole；The trapezium structure minimum dimension of 11 top surface of lower die is less than workpiece
Square hole size, trapezium structure full-size smoothly cuts off burr more than workpiece square hole size, and is capable of providing spacing；Cut inclined-plane
Base is smoothly transitted by circular arc with lower die side and is connected；It is consistent with workpiece square hole inner side edge gradient to cut slope, into one
Step improves burr excision reliability, and the transition arc for cutting inclined-plane and side is adapted with workpiece lumen circular arc, and lower die 11 stretches into
Workpiece lumen shape is can adapt to during workpiece square hole inscribe flash removed, unnecessary deformation will not be caused to workpiece；Lower die top surface
For the less arc-shaped curved surface of radian, upper mold bottom surface has the curved surface being adapted with lower die top surface, the less arc-shaped curved surface of radian
There is guidance quality so that upper mold is smoothly crimped with lower die in workpiece square hole, further improves burr excision stability.
The big arm support deburring stamping die of windshield wiper of the utility model, by coordinating at the top of lower die with upper mold bottom
Crimping, installation square hole punching press excision installation square hole edge is upward through by the cutting inclined-plane of surrounding at the top of lower die from workpiece lumen
Burr, can be used on continuous producing apparatus, and can automatically removing burr mould, without subsequent artefacts polish, size essence
Degree is high, and product quality is stablized, and production efficiency is high, and production cost is low.
