Description
Technical field
The present invention relates to automobile gearbox return component, a kind of specifically automobile gearbox return component riveting work
Dress.
Background technology
At present, the country possesses autonomous AT gearboxes（Automatic transmission automatic gear-box）The enterprise of technology
Relatively fewer, most of gearbox manufacturing enterprises are still in development phase, the manufacturing of its big multiple component to AT gearboxes
Technique is substantially all immature.Gearbox return spring component belongs to gear shifting actuating mechanism, is by one group of cylindrical screw bullet in structure
Spring is by riveting process, on riveting in parallel to a piece of stamping forming spring stop, gear of the main engine plants to return component after riveting
Plate flatness and the verticality of spring opposing flaps all have higher requirements.Since this spring stop is very thin, if being produced during riveting
Raw excessive plastic deformation may influence planarity requirements, but there are one to pulling-out force that each spring rivets for return component
Provisioning request, so the requirement to riveting frock in manufacturing process is of a relatively high, domestic many trial-production manufacturers cannot reach this
It is a little to require.
The content of the invention
It is an object of the invention to provide a kind of automobile gearbox return component riveting frock, can realize spring according to certain
It is required that riveting is on spring stop, and meet requirement.
Technique according to the invention scheme, the automobile gearbox return component riveting frock, including mold and lower die
Tool, the mold includes cope plate, upper die plate, upper mould fixed plate, discharging spring, fixed column, stripper and punch, described
Cope plate, upper die plate and upper mould fixed plate are fixedly connected sequentially；Stripper is installed on cope plate using discharging spring；Upper mold
Fixed plate is equipped with fixed column and some punches, and fixed column can move up and down in the guide groove of fixed plate；The lower mould
Including lower template, lead core return spring, lower mold backing plate, bottom plate, lower mold fixed plate, lead core and limited post, the lower template,
Lower mold backing plate and lower mold fixed plate are fixedly connected sequentially；Groove is provided with the contact surface of lower mold backing plate and lower mold fixed plate, under described
Die shoe plate is arranged in groove；The core of leading is located in the through hole set in lower template, lower mold backing plate and lower mold fixed plate, and fixed
On bottom plate, lead core and corresponded with punch；The via bottoms of lower template are equipped with screw plug with holes, and the lower end for leading core passes through band
The hole of hole screw plug, leads core return spring and is sleeved on the lower part for leading core, be arranged between bottom plate and screw plug with holes；Lower mold fixed plate
Multiple limited posts are equipped with, the height of limited post, which is higher than, leads core.
Further, the cope plate is equipped with guide post, and the position opposite with guide post is equipped with guide sleeve in the lower template.
Further, the end sidewalls of the punch are central raised arcwall face.
Compared with prior art, the advantage of the invention is that：Simple in structure, cost is relatively low, and working service is convenient；Punch
End sidewalls efficiently control the deflection of thin plate during riveting for central raised arcwall face, and plastic deformation is controlled in bullet
At spring baffle aperture, the influence that riveting produces baffle plane degree is reduced；Core and punch are led by spring, significantly reduce spring
The inclination produced during riveting, effectively controls the squareness tolerance of return component after riveting；It is raw equipped with automatic discharging plate
Produce efficiency and the degree of automation is high；Equipped with position-limit mechanism, prevent because manual operation or press failure cause spring conquassation.

Embodiment
With reference to specific embodiments and the drawings, the invention will be further described.
Automobile gearbox return component riveting frock as depicted, including mold and lower mould.Mold includes upper
Template 1, upper die plate 2, upper mould fixed plate 3, discharging spring 4, fixed column 5, stripper 7 and punch 8, wherein cope plate 1, upper mold
Backing plate 2 and upper mould fixed plate 3 are fixedly connected sequentially from top to down using bolt；Stripper 7 is installed on upper mold using discharging spring 4
On plate 1；Upper mould fixed plate 3 is equipped with fixed column 5 and some punches 8, and fixed column 5 can be in the guide groove of fixed plate 3 up and down
It is mobile.Lower mould includes lower template 9, leads core return spring 10, lower mold backing plate 11, bottom plate 12, lower mold fixed plate 13, leads core
15 and limited post 16, lower template 9, lower mold backing plate 11 and lower mold fixed plate 13 be fixedly connected sequentially from below to up using bolt；Under
Be provided with groove on the contact surface of die-cushion plate 11 and lower mold fixed plate 13, bottom plate 12 be arranged in groove and can in groove on move down
It is dynamic；Lead core 15 to be located in the through hole set in lower template 9, lower mold backing plate 11 and lower mold fixed plate 13, and be fixed on bottom plate
On 12, lead core 15 and corresponded with punch 8；The via bottoms of lower template 9 are equipped with screw plug 19 with holes, and the lower end for leading core 15 passes through band
The hole of hole screw plug 19, leads core return spring 10 and is sleeved on the lower part for leading core 15, be arranged between bottom plate 12 and screw plug with holes 19；
Lower mold fixed plate 13 is equipped with multiple limited posts 16, and the height of limited post 16, which is higher than, leads core 15.
It is equipped with guide post 6 on cope plate 1, the position opposite with guide post 6 is equipped with guide sleeve 14 in lower template 9, further strengthens
Locating effect.The end sidewalls of punch 8 are central raised arcwall face, have efficiently controlled the deformation of thin plate during riveting
Amount, by plastic deformation control at 17 aperture of spring stop, reduces the influence that riveting produces 17 flatness of spring stop.
Operation principle：Need to be used as power using aerostatic press during riveting and be pressed on cope plate, cope plate is pressed downwardly onto
Designated position, punch 8 will rivet aperture and open on spring stop 17, complete the riveting to spring stop 17 and spring 18.
When riveting starts, first spring stop 17 and workpiece spring 18 are positioned over to be sleeved in lower template 9 in sequence and lead core
On 15, leading core 15 can prevent workpiece spring 18 from being fallen since crooked or even side occurs for various factors, when mold moves downward,
Stripper 7 is contacted with limited post 16 first, not yet reaches press stroke at this time, and mechanism continues to move downward, at this time discharging spring 4
Can be compressed, and punch 8 can also contact and lead core 15, while leads core return spring 10 and will be compressed, lead core 15 can with punch 8 to
Lower movement, while bottom plate 12 also synchronously declines due to pressure, when press reaches predetermined stroke, punch 8 just may be used at this time
Aperture to be opened by the curved profile of punch, by 18 workpiece spring riveting, 17 spring stop, and fixed column 5 can push up at this time
Upper die plate 2, stripper 7 cannot continue opposite mold and move upwards, at this time limited post 16 may be prevented from mold continue to
Lower movement, can effectively protect whole device.
After the completion of riveting, mold starts to back out upwards, and at this time, punch 8 moves upwards, leads core 15 due to leading core return bullet
Spring 10 can prevent the workpiece that riveting is completed from shifting with 8 upward return of punch, and bottom plate 12 can rise at the same time herein,
Until top stops to lower mold fixed plate 13, prevention is led core 15 and is continued up；Simultaneously as the rigidity of discharging spring 4 is larger,
So during rising on the upper mold, stripper 7 can withstand limited post 16, prevent since the frictional force that plastic deformation produces makes
Riveting complete workpiece be sticked on mold punch 8, can effective guarantee pipeline system production.
