Specific embodiment
Specific introduce is made to the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figures 1 to 5, a kind of mold 100 for edge rolling, comprising: upper die holder 10, lower die holder 20, inner support column
21, the sliding block 22, two of upper die forming block 11, two side pushes away formed punch 12, thumb wheel 23, pusher dog bracket 13 and pusher dog 14.
Specifically, inner support column 21 is supported the inner sidewall of part to be processed.The outer surface of inner support column 21 is
Cylindrical surface.Predeterminated position part to be processed being socketed on the outer surface of inner support column 21.Two sliding blocks 22 are respectively to being added
The left and right ends of work part carry out molding binder.Upper die forming block 11 carries out molding binder to the upper end of part to be processed.When upper
When die holder 10 is moved relative to lower die holder 20 to molding direction, two sides push away formed punch 12 and push two sliding blocks 22 to inner support respectively
The direction of column 21 moves, until contacting part to be processed and carrying out molding binder to the both ends of part to be processed.Simultaneously upper mold at
Type block 11 contacts part to be processed and carries out molding binder to the upper end of part to be processed.
As a kind of specific embodiment, two sliding blocks 22 are slidingly attached to lower die holder 20.Side push away formed punch 12, upper mold at
Type block 11 and pusher dog bracket 13 are fixed to upper die holder 10.Inner support column 21 is installed to lower die holder 20.Inner support column 21 is set to two
Between a sliding block 22.
Specifically, upper die holder 10 drives driving oblique when upper die holder 10 is moved relative to lower die holder 20 to molding direction
Face 121 moves downward.Driving inclined-plane 121 and cooperation inclined-plane 221 pass through 22 transverse movement of inclined-plane mating band movable slider.Two sliding blocks
22 inside support column 21 is close under the action of two sides push away formed punch 12 respectively, carries out molding pressure to the both ends of part to be processed
Material.
As a kind of specific embodiment, side pushes away formed punch 12 and is formed with driving inclined-plane 121.Sliding block 22 is formed with and drives
The cooperation inclined-plane 221 that inclined-plane 121 cooperates.Driving inclined-plane 121 favours the direction that upper die holder 10 is moved relative to lower die holder 20.Match
It is equal relative to the angle of 10 direction of motion of upper die holder with driving inclined-plane 121 to close inclined-plane 221.Driving inclined-plane 121 and cooperation inclined-plane
221 is parallel.
After upper die forming block 11 and two sliding blocks 22 carry out molding binder to part to be processed, pusher dog 14 is in upper die holder 10
The driving rotation of thumb wheel 23 is when moving relative to lower die holder 20 to die sinking direction to drive inner support column 21 around the rotation of thumb wheel 23
Axis rotates certain angle, so as to be processed zero on the cylindrical surface for being socketed in inner support column 21 when inner support column 21 rotates
Part carries out circumferential grinding to improve the circularity of part to be processed.
In mold die sinking, upper die holder 10 is moved to die sinking direction relative to lower die holder 20 and is moved upwards.At this point, upper mold
Seat 10 drives pusher dog 14 to move upwards.Pusher dog 14, which stirs thumb wheel 23, makes thumb wheel 23 rotate, to drive 21 turns of inner support column
Dynamic move angle.Thumb wheel 23 is fixed to support column 21.The pivot center of thumb wheel 23 and the pivot center of support column 21 are with always
Line.
As a kind of specific embodiment, thumb wheel 23 is fixed to inner support column 21.Pusher dog 14 is rotatablely connected to pusher dog branch
Frame 13.Thumb wheel 23 is formed with the moving tooth 24 cooperated with pusher dog 14.
As a kind of specific embodiment, pusher dog bracket 13 connects restricted pusher dog 14 and rotates relative to pusher dog bracket 13
The position limiting structure 15 of position.Specifically, position limiting structure 15 is spacer pin；Spacer pin is fixed to pusher dog bracket 13.
As an alternative embodiment, position limiting structure can also be formed by pusher dog bracket, or perhaps position limiting structure
A part as pusher dog bracket.
Specifically, pusher dog 14 is under the effect of gravity in perpendicular to pusher dog bracket when pusher dog 14 is not contacted with thumb wheel 23
13 nature.When upper die holder 10 is moved relative to lower die holder 20 to molding direction, moving tooth 24 and the pusher dog 14 of thumb wheel 23 are connect
Touching, pusher dog 14 rotate under the active force for the gravity for overcoming pusher dog 14 that moving tooth 24 applies relative to pusher dog bracket 13, from
And pusher dog 14 is collapsed, allow pusher dog bracket 13 to continue to move completion molding to molding direction, after completing molding, pusher dog 14 is in weight
The nature perpendicular to pusher dog bracket 13 is returned under power effect, opens pusher dog 13.When upper die holder 10 relative to lower die holder 20 to
When being opened direction movement, position limiting structure 15 is contacted with pusher dog 14 prevents the opposite pusher dog bracket under the active force of thumb wheel 23 of pusher dog 14
13 rotate, and pusher dog 13 cannot open bigger angle.Pusher dog 14 is dialled under the drive of upper die holder 10 by the driving of moving tooth 24
23 rotation of wheel is to drive inner support column 21 to rotate.
Inner support column 21 is rotated when mold is opened, and the inner wall of edge rolling part is made to realize higher circularity.
As a preferred embodiment, upper die holder 10 is moved to die sinking position from die-closed position relative to lower die holder 20
When, pusher dog 14 drives thumb wheel 23 to rotate 90 degree.
As a preferred embodiment, thumb wheel 23 includes 4 moving teeth 24；Rotation axis of 4 moving teeth 24 in thumb wheel 23
It is uniformly distributed in the circumferential direction of line.
When mold 100 is opened, side pushes away formed punch 12 and moves upwards disengaging in the contact of sliding block 22.Resetting apparatus drives two cunnings
Block 22 is completed to reset to the direction sliding from inner support column 21 returns to initial position.As a kind of specific embodiment, reset
Device is air spring.
Inner support column 21 is moved along the pivot center direction of thumb wheel 23 to be detached from part to be processed.Part to be processed and interior branch
Dagger 21 separates, and staff takes out part to be processed with can be convenient.As a preferred embodiment, thumb wheel 23 drives
Inner support column 21 slides to be detached from part to be processed relative to lower die holder 20 along the pivot center of thumb wheel 23.The rotation of thumb wheel 23
Glide direction of the axis perpendicular to sliding block 22.The pivot center of thumb wheel 23 and the glide direction of sliding block 22 are each perpendicular to upper die holder 10
The direction moved relative to lower die holder 20.
As a kind of specific embodiment, the mold 100 for edge rolling further includes hand control valve 25.By controlling hand
Dynamic control valve 25 drives thumb wheel 23 to slide that inner support column 21 is driven to slide relative to lower die holder 20 relative to lower die holder 20.
Mold 100 for edge rolling further include prevented when the opposite lower die holder 20 of interior support column 21 slides part to be processed with
The stop configurations slided with inner support column 21.As a kind of specific embodiment, stop configurations are fixed block 26.It is fixed
Block 26 is fixed to lower die holder 20；Inner support column 21 passes through fixed block 26.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
