The combination of case is not present, also not within the protection scope of the requires of the utility model.
The utility model proposes it is a kind of can automatic material returning stamping die.
Referring to Figure 1, the utility model embodiment can automatic material returning stamping die, including be set to lower section lower die
Seat 10 and the upper die holder 1 for being set to top, 1 bottom surface of upper die holder are connected with cavity plate 6, and 6 bottom of cavity plate is equipped with moving up and down
Ejector block 5,5 inner concave of ejector block and 6 inner concave of cavity plate collectively constitute the groove to match with 12 top peripheral face of punch-pin, ejector block
5 tops are connected with the push rod 3 for passing through upper die holder 1, and 3 middle part outer peripheral surface of push rod is equipped with stop collar 31, are equipped with and fix at the top of upper die holder 1
Seat cavity 2 is equipped with the first spring 4 between 2 inner top surface of 31 top surface of stop collar and fixing seat cavity and is placed on 3 outer peripheral surface of push rod；Punch-pin
12 bottoms are fixedly linked with lower die holder 10, and binder block 8 is equipped between cavity plate 6 and lower die holder 10 and is placed on 12 outer peripheral surface of punch-pin, binder
8 bottom surface of block is connected by mandril 11.Preferably, 11 end of mandril of the present embodiment is connected and is pushed with hydraulic cylinder.
When the stamping die of the present embodiment is processed, the metal plate part 13 being not yet plastically deformed is placed in binder block 8 first
Then the position between cavity plate 6 drives mandril 11 upwards by hydraulic cylinder, to pass through binder block 8 and cavity plate 6 for metal plate part 13
It grips in advance, then drives punch-pin 12 gradually to move up by driving lower die holder 10, so that punch-pin 12 passes through in binder block 8
The mesoporous in portion and the bottom surface for being butted on metal plate part 13, are constantly moved up by punch-pin 12, so that plastic deformation occurs for metal plate part 13 simultaneously
It gradually fits on the inner concave that ejector block 5 and cavity plate 6 form, punch process has can be completed in such metal plate part 13, and works as metal plate part
After 13 have completed plastic deformation, punch-pin 12 moves down by lower die holder 10 and exits the centre bore of binder block 8, same with this
When, drive mandril 11 to move down by hydraulic cylinder, so that the drive of binder block 8 be moved down.Due to being set to metal plate part 13
For the push rod 3 of top after the upward active force of no punch-pin 12, the upper end of the first spring 4 is butted on 2 inner top surface of fixing seat cavity, and
The lower end of first spring 4 is butted on 31 top surface of stop collar, carries out axis thereof by the first spring 4 to push push rod 3 to moving down
It is dynamic, so that ejector block 5 imposes down force to the outer convex bottom face of metal plate part 13 and pushes down on metal plate part 13 to push away metal plate part 13
Out outside cavity plate 6.After being moved down due to ejector block 5, in ejector block 5 and cavity plate 6 between there are gaps, can effectively weaken metal plate part 13
With the negative pressure between cavity plate 6, metal plate part 13 can be displaced outwardly easily and realize the effect for being detached from cavity plate 6, to substantially reduce
Manually-operated working strength and raising working efficiency.
Referring to Figure 1, the edge rounding off between 6 inner concave of 5 inner concave of ejector block and cavity plate of the present embodiment, thus
So that metal plate part 13 is by punch-pin 12 to occurring inside cavity plate 6 to avoid too small between ejector block 5 and metal plate part 13 in plastic history
Contact area and stress is generated on metal plate part 13 and concentrates and influences the presentation quality of final finished.
Referring to Figure 1, it is equipped with second spring 9 between the binder block 8 and lower die holder 10 of the present embodiment and is placed on 11 periphery of mandril
Face can enhance the active force of the fixed metal plate part 13 of binder block 8, prevent from occurring in 13 punching course of metal plate part by the way that second spring 9 is arranged
Displacement.At the same time, during second spring 8 moves down binder block 8, the directly impact of binder block 8 will not occur under
10 top surface of die holder and cause noise and influence Impact mould service life.
Referring to Figure 1, it is respectively equipped with rubber pad 7 between 8 top surface of 6 bottom surface of cavity plate and binder block of the present embodiment, by setting
When setting rubber pad 7 makes binder block 8 and cavity plate 6 be fixedly clamped jointly to metal plate part 13, metal plate part 13 will not be made to move easily
And influence end product quality.In the other embodiments of the utility model, 6 bottom surface of cavity plate is respectively equipped with 8 top surface of binder block
Knurling structure, it is recessed by increasing when by surface setting knurling structure cavity plate 6 and binder block 8 being clamped jointly to metal plate part 13
Static friction active force between mould 6 and metal plate part 13 and between binder block 8 and metal plate part 13, so that metal plate part 13 be effectively prevent to strike out
Being displaced during type influences final product quality.
Referring to Figure 1, it is threadedly engaged and is connected with internal thread hole by bolt between the upper die holder 1 and cavity plate 6 of the present embodiment,
It is threadedly engaged and is connected with internal thread hole by bolt between lower die holder 10 and punch-pin 12, by helicitic texture, so that 1 He of upper die holder
Cavity plate 6 is securely fixed connected, is reliably connected between lower die holder 10 and punch-pin 12, is connected at the same time by using bolt
Structure, so that structure is more readily replaceable or repairs.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all under the design of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or
Directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
