Description
Technical field
The utility model relates to hardware processing machinery fields, and in particular to a kind of buffer limit knot for stamping die
Structure.
Background technique
Stamping parts generally passes through stamping die cold stamping and realizes, stamping die generally comprises upper die and lower die, to be punched
Component is placed in lower die, upper mold downlink under the action of press machine, when to be punched on the workpiece and lower die in upper mold
After workpiece effect, workpiece stress to be punched deforms, and then becomes required Auto-body Panel.On the upper surface of lower die usually
Work limited block is set, will be in contact with work limited block when upper mold downlink, and then realize the sports limiting of upper mold.On however,
Mould and work limited block contact pier are dead, and the two rigid contact causes upper mold and work to limit since the pressure of press machine output is larger
Active force between the block of position is larger, and upper die and lower die are easy to appear damage.And how to realize between upper mold and work limited block
Buffering, while reducing the cost of stamping die, it has also become those skilled in the art's technical problem urgently to be resolved.
Utility model content
For the deficiency in the presence of the prior art, the utility model provides a kind of buffer limit for stamping die
Structure, structure is simply firm, can effectively slow down punching press vibration, extend die life.
To achieve the above object, the utility model uses a kind of the following technical solution: buffering for stamping die
Position limiting structure, including upper mold and lower mold set mounting base on lower mold, buffer limit mechanism, buffer limit are set in mounting base
Mechanism includes limited post, buffering sleeve, buffer spring, and limited post is mounted in mounting base by support, and buffering sleeve is set in
Limited post upper end, buffer spring are set on the limited post between buffering sleeve and support, and buffering sleeve lower end surface opens up annular groove,
One end of buffer spring is connected in support, and buffer spring is another to be terminated in annular groove, and upper mold is equipped with corresponding with buffering sleeve
Punching press stake, punching press stake end face open up the accommodating chamber for limited post insertion.Punching press stake produces downward pressure to buffering sleeve, in spring
Under the action of, which is buffered, while limited post is inserted into punching press stake, withstands accommodating chamber cavity bottom at the top of limited post
When upper mold is limited.
Further, mounting base is equipped with the mounting groove cooperated with support, and the cell wall of mounting groove is equipped with the spiral shell of crescent shape
Revolve rib.
Further, support periphery is equipped with the helicla flute cooperated with spiral ribs.
Further, lower mold is equipped with the groove for accommodating mounting base, and groove cell wall is equipped with clamping block, mounting base both ends
Equipped with the card interface cooperated with clamping block, lower mold side is inserted with the bolt for being fixedly connected with mounting base with clamping block.
Further, cushion is equipped in accommodating chamber.Prevent limited post with accommodating chamber cavity bottom because shock is damaged.
Compared with the prior art, the utility model has the following beneficial effects:
The utility model structure is simply firm, and buffering effect is strong, and punching press stake produces downward pressure to buffering sleeve, in spring
Under the action of, which is buffered, while limited post is inserted into punching press stake, withstands accommodating chamber cavity bottom at the top of limited post
When upper mold is limited, while further preventing under the action of cushion limited post and accommodating chamber cavity bottom because hitting
It is damaged, and then by buffering and limits vibration when reducing mould punching, extend the service life of mold.
