Drawings
FIG. 1 is a schematic diagram of a metal hot press molding apparatus according to an embodiment of the present invention;
fig. 2 is a top view of the metal hot press forming apparatus according to the embodiment of the present invention.
Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.
The metal hot-press forming device provided by the embodiment comprises a lower die component and an upper die component, and the specific structure is shown in fig. 1. The lower die component comprises a die body 6 and a die embedding opening 4, and a notch corresponding to the shape required by hot press molding of the metal material is formed in the upper surface of the die body 6. The female die rabbet 4 is fixed at the outer edge of the notch through a screw.
In addition, as shown in fig. 2, a plurality of positioning plates 7 distributed along the circumferential direction are further mounted on the die body 6, and the metal material to be hot-press molded can be fixed and positioned with high precision by the plurality of positioning plates 7, so that the metal material can be closely attached to the notch and the upper side of the die insert 4. The positioning plate 7 is provided with the oval strip holes, the oval strip holes have a unidirectional adjusting function, the positions of the positioning plate 7 can be adjusted according to the size of a metal material through the strip holes, and the die repairing times are reduced.
The upper die component in the hot press forming device of the embodiment comprises an upper die assembly 1 and a male die 5, wherein the shape of the male die 5 corresponds to the shape of the notch. The upper die assembly 1 is connected with the male die 5 through a screw, and can drive the male die 5 to move in the vertical direction so as to control the distance between the male die 5 and the notch and realize the hot press forming of the metal material between the female die body 6 and the male die 5.
When the hot press molding apparatus proposed in this embodiment is used to hot press mold a metal material, the die insert 4 is located at a position where the metal material starts to deform, so that the requirement for the material performance is high here, and the requirement for the material performance at other positions is low. Therefore, in this embodiment, the die insert 4 is made of a material selected to have superior high temperature resistance and strength to the die body 6. Like this, can avoid whole die body 6 all to adopt the high temperature high strength material of the high performance of expensive price to reduce the quantity of high temperature high strength material in the mould, can be under the prerequisite of guaranteeing the hot briquetting effect, reduce whole hot briquetting device's cost. Meanwhile, because the female die inlaying port 4 is fixed at the outer edge of the notch through a screw, when the female die inlaying port 4 is damaged through multiple times of hot press forming, the female die inlaying port 4 only needs to be replaced, the use of the female die can be ensured, the time and the cost for replacing the whole female die body 6 can be saved, and the disassembly and the repair and the adjustment are convenient.
In addition, still be fixed with support composite member 3 through the screw at the upper surface of die cavity 6, still be fixed with stripper 2 through bolt and nut in the upper end of support composite member 3. The stripper 2 also adopts the spill design, and the notch size of stripper 2 cooperatees with terrace die 5, not only can guarantee that terrace die 5 passes through smoothly, can also realize the purpose of unloading. In a normal case, when the metal material is subjected to hot press forming and is released from the mold, the metal material is stuck to the male mold 5, and separation between the material and the mold cannot be achieved. But when using a support assembly 3 to be fixed in stripper 2 in the take the altitude department of the upper surface of die body 6, drive terrace die 5 and rise to a take the altitude when last die assembly 1, the edge of metal material can take place mechanical contact with stripper 2, through the counter force that stripper 2 provided for metal material and terrace die 5 accomplish the separation, and need not improve separation efficiency with the help of other complicated device or technology. Similarly to the positioning plate 7, the stripper plate 2 is also provided with oval-shaped slots to facilitate adjustment according to the size of the metal material.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
