Abstract
The utility model discloses a male die protection mechanism of a punching die, and relates to a die component. The male die protection mechanism comprises a male die, wherein the male die is fixedly connected with the lower portion of an upper die base through a male die fixing plate, a protection sleeve is sleeved outside the male die, the protection sleeve is a hollow cylinder body with two opening ends and is divided into an upper protection sleeve and a lower protection sleeve, the upper protection sleeve is meshed with the lower protection sleeve, the upper protection sleeve is arranged in an upper pressing plate fixedly connected with the lower surface of the male die fixing plate, the lower end of the lower protection sleeve is fixedly connected with a discharge plate through a lower pressing plate, the upper end of the lower protection sleeve extends into the upper pressing plate, the discharge plate is connected with the upper die base through a discharge screw which is connected with a spring in a sleeved mode, and the lower protection sleeve can slide relative to the male die and the upper pressing plate. The male die protection mechanism can protect the male die, prevents the male die from breaking, prolongs service life of the male die, is simple in structure, improves production efficiency, reduces die cost and is very practical.
Description
Technical field
The utility model relates to a kind of mold component, relates in particular to a kind of stamping die punch protection mechanism.
Background technology
Punching press is at room temperature to utilize the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out processing and forming such as punching, blanking, bending and pull and stretch.The quality of stamping parts, production efficiency and production cost etc. have direct relation with mould design and manufacturing.When using existing diel to carry out the aperture moulding, its corresponding punch is elongate rod, and strength and stiffness are poor, is easy to will often shut down the replacing punch because strut buckling causes the punch fracture when stamping-out, has reduced operating efficiency, has increased die cost.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of stamping die punch protection mechanism, can protect punch; avoid the punch fracture, prolong the service life of punch, and simple in structure; improve production efficiency, reduced die cost, very practical.
The technical solution of the utility model is: a kind of stamping die punch protection mechanism, comprise punch, punch is fixedly connected on the upper bolster below by punch retainer, punch is socketed with sheath outward, described sheath is the cylindrical shell of both ends open, hollow, sheath is divided into upper jacket and lower jacket, upper jacket and lower jacket are meshing with each other, upper jacket is arranged in the top board, top board is fixedly connected on the punch retainer lower surface, the lower jacket lower end is fixedly connected on the stripper by lower platen, and the upper end is stretched in the top board; Stripper is connected with upper bolster by the discharging screw, is socketed with spring on the discharging screw, and lower jacket is punch and top board slip relatively.
As preferably, punch adopts the GCr15 steel to make, and punch retainer adopts 45 steel to make, and is provided with backing plate between punch and the upper bolster, and backing plate adopts 45 steel to make.
As preferably, have on upper jacket and the lower jacket be used to the fan groove that is engaged with each other, the end face that upper jacket contacts with lower jacket is set to 60 degree sectors respectively.
The beneficial effects of the utility model are: sheath of the present utility model is socketed on convex mould surface; simple in structure; easy to assembly; sheath is divided into upper and lower sheath; be engaged with each other and end face is and is slidingly matched; when punching press; the fan groove of upper and lower sheath is in engagement all the time; punch all is among the sheath except lower end stamping-out part, makes punch almost lose buckling deformation even the possibility that fractures, and has improved the strength and stiffness of punch; prolonged the service life of punch greatly; reduced and shut down the time of safeguarding, improved operating efficiency, reduced die cost.Punch adopts the GCr15 steel to make, the intensity height, and easy fracture is not very practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model; as shown in Figure 1; a kind of stamping die punch protection mechanism; comprise punch 3; punch 3 is fixedly connected on the upper bolster below by punch retainer 5; the punch 3 outer sheaths that are socketed with; described sheath is both ends open; the cylindrical shell of hollow, sheath are divided into upper jacket 6 and lower jacket 2, and upper jacket 6 and lower jacket 2 are meshing with each other; in the present embodiment; as preferably, have fan groove on upper jacket 6 and the lower jacket 2, fan groove is preferably three; along circumferentially evenly distributing of upper jacket 6 and lower jacket 2, upper jacket 6 and lower jacket 2 are engaged with each other by fan groove.The end face that upper jacket 6 contacts with lower jacket 2 is set to 60 degree sectors respectively, is between sector to be slidingly matched, and it is little to rub, long service life.Upper jacket 6 is arranged in the top board 7, and top board 7 is fixedly connected on punch retainer 5 lower surfaces, and lower jacket 2 lower ends are fixedly connected on the stripper 1 by lower platen 8, and the upper end is stretched in the top board 7; Stripper 1 is connected with upper bolster by the discharging screw, is socketed with spring on the discharging screw, and lower jacket 2 is punch 3 and top board 7 slips relatively.
In the present embodiment, as preferably, punch 3 adopts the GCr15 steel to make intensity height, long service life.Punch retainer 5 adopts 45 steel to make, and is provided with backing plate 4 between punch 3 and the upper bolster, and backing plate 4 adopts 45 steel to make, and to the impact of upper bolster, prolongs the service life of upper bolster when backing plate 4 can reduce punching press.
More than a kind of stamping die punch protection mechanism provided by the utility model has been carried out detailed introduction, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.To change of the present utility model with to improve will be possible, and can not exceed design and the scope that accessory claim can be stipulated.
