Description
Technical field
The utility model relates to a kind of blanking die.
Background technology
Handle meeting and the wall collision of opening the door at every turn and always worrying door cause wall to be damaged, and affect outward appearance; If there has been the door lock pad just can be relieved, the wall that it can protect you can not collided by door handle again.The blanking die that for this reason needs a kind of punching out lock pad.Blanking die is the profile along sealing separates product or process part processing with plate punch die,
The utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to use, blanking die that efficient is high.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is: blanking die, comprise successively from top to bottom: die shank, convex mould base, upper padding plate, fixed head, punch, stripper, die and die socket, it is characterized in that: be provided with guide pillars and bushes between described convex mould base and the die socket, described die is provided with alignment pin in billot direction of feed and side thereof.
Amplify on described punch top, and the upper end is set in case the band shoulder structure of leaving behind; Punch and fixed head closely cooperate.
As preferred version, the sword cornice of described die is gradient; Leave the cutting edge gap between described punch and die.
Beneficial effect: the blanking die that the utility model provides, simple in structure, easy to use, automation efficient height, good product quality; Discharging is effective, and is easy to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, be a kind of blanking die, comprise successively from top to bottom: die shank 1, convex mould base 2, upper padding plate 3, fixed head 4, punch 5, stripper 6, die 7 and die socket 8, it is characterized in that: be provided with guide pillar 9 and guide pin bushing 10 between described convex mould base 2 and the die socket 8, described die 7 is provided with alignment pin 11 in billot direction of feed and side thereof; Amplify on described protruding 5 mould tops, and the upper end is set in case the band shoulder structure of leaving behind; Punch 5 closely cooperates with fixed head 4.
As preferred version, the sword cornice of described die 7 is gradient; 7 of described punch 5 and dies leave the cutting edge gap.
Blanking die in the utility model has guide pillar, guide pin bushing guiding, thereby the guidance quality the when positioning accuracy of punch and matrix and work is all better.It is H6/h5 that the guide pin bushing endoporus required with cooperating of guide pillar.The punch section is thin and delicate, and in order to gain in strength and rigidity, amplify on punch top.Punch and fixed head tight fit, upper end band shoulder is in case leave behind.Die sword cornice is gradient, rushes part and is difficult for being trapped in the sword hole, alleviates simultaneously the wearing and tearing of counter blade wall, and one time the sharpening amount is less.The cutting edge size changes with sharpening.The size of cutting edge of die has determined blanking size.The cutting edge gap is arranged between punch and die.In billot direction of feed and side thereof, alignment pin is housed, when the billot feeding, determine the stamping-out position.Workpiece is discharged from the material-dropping hole of die, billot is unloaded by stripper, this discharging that is widely used in without the guiding elastic stripper on the moulds such as the smooth blanking of thin material and part requirement, punching, compound die, and suppressing element can be with spring or ebonite board, discharging is effective, and is easy to operate.
Below disclose the utility model with preferred embodiment, so it is not to limit the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode obtains, all drops within the protection domain of the present utility model.
