Description
Technical field
This technology is related to cold-working processing tool field, provides a kind of spoke stretching preforming and end face leveling die, uses
The mold can complete spoke in higher quality on a station and stretch two operation break-downs of preforming and end face smoothing.
Background technique
Spoke connects the part of wheel rim and wheel hub on wheel.As the wheel rim of wheel of vehicle, the device of spoke is protected, take turns
Spoke is one of wheel important component, it is characterized in that a pair of of circle cover plate, the diameter of cover plate and the diameter of wheel rim connect
Closely, there is the hole greater than axis of wheel rotation in the center of cover plate, has aperture in the part at cover plate close to edge, there is annular at the edge of cover plate
The curved surface of wheel plate, wheel plate can be fitted closely with the curved surface of wheel rim.
Spoke mostly uses the plate cutting with preferable ductility, is process through cold-working.
Plate with a thickness of 3 ~ 5mm, but it is the most commonly used with a thickness of the plate of 4mm.
It is part mostly important, crucial in spoke cold-working producing process that wheel spoke, which stretches preforming operation,.It is existing
Have in technology, the spoke of drawn preforming process production, there are the excessive leakages of middle part material, influence spoke drawing process
The stability of material distribution, causes the intensity of spoke each section unbalanced, there are the defects of stress collection, seriously affect spoke
Performance quality.
It is based on above-mentioned factor again, brings spoke end face uneven, to correct the phenomenon, ad hoc one of spoke end face is needed to smooth work
Sequence brings larger negative effect to following process, also increases spoke production cost, reduces the production efficiency of spoke.
Summary of the invention
The purpose of this technology is to provide a kind of preforming and end face leveling die of spoke stretching, can be one using the mold
Spoke is completed on a station in higher quality and stretches two operation break-downs of preforming and end face smoothing.
The purpose of this technology is achieved through the following technical solutions:
A kind of spoke stretches preforming and end face leveling die, including horizontally disposed, center line coaxial lower die and upper mold,
Upper mold is mobile to be arranged in the upper surface of lower die.
Upper mold includes that the coaxial top mold holder of center line, upper die holder, upper mold core and upper mold de- material block, upper die holder are connected firmly in upper mold
The bottom surface center of frame, upper mold core connect firmly below upper die holder, and upper mold de- material block is mobile to be arranged in upper die holder and upper mold core.
Lower die includes lower mold holder, lower die holder, lower mold core, the retainer molding ring seat of ring structure and retainer forming ring, retainer
Forming ring is connected firmly in the upper surface of retainer molding ring seat, and lower die holder connects firmly in the upper surface of lower mold holder center, and lower mold core is connected firmly in lower die
The upper surface of seat, retainer forming ring and the mobile setting of retainer molding ring seat are on lower die holder and lower mold core.
The profile of upper mold core lower end matches with the profile of spoke upper surface, and upper mold core is in outer diameter outside projection one and spoke
The convex rank that circle face height matches；The profile on lower mold core top and the inner ring surface of retainer forming ring can be with spoke lower surfaces
Profile matches.
In use, upper mold is connected firmly by the sliding block lower plane of top mold holder and lathe, lower die passes through under lower mold holder and lathe
Table top connects firmly, and starts lathe, and top mold holder part follows sliding block uplink, and upper mold de- material block is relative to top mold holder downlink in ejection shape
State.
Retainer forms ring seat, retainer forming ring relative to lower mold holder uplink, ejection.
Spoke stretched part is placed in retainer forming ring medial type chamber.
Lathe slide block down, upper mold core follow top mold holder part downlink, and the lower plane of convex rank connects at first on upper mold core outer diameter
Spoke stretched part is urged to lower plane and lower die in the middle part of spoke stretched part by wheel trolley spoke stretched part outer circle upper surface down
Plane contact on core, spoke stretched part start to carry out preforming deformation.
Lathe sliding block continues traveling downwardly, and upper mold core continues to push spoke stretched part and oppresses retainer forming ring, retainer molding
Ring seat makes its downlink, while upper mold de- material BOB(beginning of block) contacts and push down spoke stretched part, until spoke stretched part is complete
It is pressed together on the intracavitary preforming operation break-down of stretching for completing spoke of type of upper and lower mold core.
During entirely stretching preforming pushing, the lower plane of convex rank compresses spoke always and stretches work on upper mold core outer diameter
Part outer circle upper surface, until stretching preforming operation completes molding, the position of spoke excircle of workpiece upper surface and spoke it is preforming on
The design position size of the lower plane of convex rank is consistent in mandrel diameter, reaches and completes the workpiece outer diameter that spoke stretches preforming processing
Face height position consistency completes spoke end face and smooths operation break-down.
The beneficial effect of this technology is: preforming and end face leveling die is stretched using a set of above-mentioned spoke, it can be one
Spoke is completed on a station in higher quality and stretches two operation break-downs of preforming and end face smoothing.
As the improvement to this technology, the convex rank of projection to match with spoke circle end face height on upper mold core outer diameter
702 width is the thickness of a spoke workpiece plate；One material thickness is 3 ~ 5mm, takes this with a thickness of 4mm.
This improvement provides a reliable positioning base to the workpiece outer-diameter end face that smoothing spoke stretches preforming processing
It is quasi-.
As the further improvement to this technology, connects firmly the mobile setting of the guide sleeve in top mold holder and connecting firmly on lower mold holder
On the guide post in face.
This improvement, using the advantage of guide post sliding block pair, so that mobile be arranged in lower die of upper mold has accurate guiding
Effect.
As the further improvement to this technology, is erected in upper die holder and upper mold core and set cylinder, the cylinder body and upper mold of cylinder
Seat connects firmly, piston rod and upper mold de- material block are hinged；It is additionally provided between upper mold de- material block and upper mold core de- for limiting upper mold
Expect the limiting device of block downlink extreme position.
This improvement, using cylinder driving upper mold de- material block move up and down and for upper mold de- material block compress spoke stretch work
Part provides reliable and lasting power, easy to operate；Limiting device can guarantee that upper mold de- material block is mobile always again and be arranged upper
Without departing from reliability is higher in die holder and upper mold core.
As the further improvement to this technology, the top of circumferential uniformly distributed, the mobile movable ejector beam being arranged in lower mold holder
It holds and is abutted against with the bottom surface of retainer molding ring seat.
This improvement provides power using the lifting that the hydraulic die cushion of lathe forms ring seat, retainer forming ring for retainer, easily
In implementation.
As the further improvement to this technology, the spiral shell for connecting with lathe is all offered in top mold holder and lower mold holder
Pit.
