Detailed Description

The core of the specific embodiment is to provide a limiting structure, and the limiting structure can prevent the forge piece of the sectional forming die from transverse displacement in the longitudinal moving process, so that the problem in the field at the present stage is solved.

Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

The limiting structure provided by the specific embodiment is applied to limiting of a segmented forming die and is characterized by comprising a boss 1 and a groove 2; the boss 1 and the groove 2 can move relatively in the longitudinal direction, and can realize limit in the transverse direction. During actual design, boss 1 and recess 2 of limit structure can be located the different sections that segmentation forming die needs to match respectively to make boss 1 and recess 2's cooperation enough make segmentation forming die vertically take place relative movement, can transversely carry on spacingly to segmentation forming die again, and then satisfy large-scale die forging's design demand. Therefore, the utility model provides a limit structure can make segmentation forming die horizontal misposition can not appear at longitudinal movement in-process forging, has solved the difficult problem in this field at present stage. Please refer to fig. 1.

In the limiting structure provided by the present embodiment, the positions where the boss 1 is matched with the groove 2 are the top surface 3 and the two side surfaces 4 of the boss 1; wherein, the top surface 3 of the boss 1 is contacted with the bottom surface of the groove 2 in a matching way; two sides 4 of boss 1 respectively with two inner wall phase-match contacts of recess 2, and then can make and can vertically realize sliding between boss 1 and the recess 2 to can make and transversely realize spacing between the two, and then ensure that the mould can not appear transversely the mispositioning between longitudinal movement's in-process forging.

Further, among the above-mentioned limit structure, can design the top surface 3 of boss 1 for cambered surface, plane, perhaps other can with the bottom surface of recess 2 face of cooperateing the contact, and can make and can not appear horizontal dislocation when taking place longitudinal movement between boss 1 and the recess 2.

In order to better realize the longitudinal sliding between the top surface 3 of the boss 1 and the bottom surface of the groove 2, the top surface 3 of the boss 1 can be designed into an arc surface, and the bottom surface of the groove 2 can also be designed into an arc surface matched with the top surface 3, so that the freedom of the longitudinal sliding between the boss 1 and the groove 2 is ensured.

In the limiting structure provided by the present embodiment, the top surface 3 of the boss 1 may be designed as a concave arc surface, that is, the top surface 3 is designed as an arc surface with two ends tilted and a middle concave; correspondingly, the bottom surface of the groove 2 can be designed to be a convex arc surface matched with the arc-shaped top surface 3, namely, the bottom surface of the groove 2 can be designed to be a convex arc surface with the middle convex and two ends sinking.

Above-mentioned limit structure, side 4 of boss 1 can be the inclined plane, and the incline direction of this side 4 can be towards the central point of forging puts or keeps away from the intermediate position of forging, in order to guarantee to realize vertically smooth and easy the removal between boss 1 and the recess 2, need with the inner wall design of recess 2 for with this side 4 assorted inclined plane, in order to guarantee longitudinal self-sliding between the two.

In the limiting structure provided by the specific embodiment, the two side surfaces 4 of the boss 1 can be designed into inclined surfaces, the two inner walls of the groove 2 are designed into inclined surfaces respectively matched with the two side surfaces 4 correspondingly, and the design basis is that the boss 1 and the groove 2 can longitudinally move.

Further, in the above-mentioned limit structure, both side surfaces 4 of the boss 1 may be designed in a manner of inclining from the top surface 3 of the boss 1 to the outer side of the boss 1; in the same way, the two inner walls of the groove 2 are designed to be of an inclined design matching the two side faces 4 of the boss 1.

This embodiment provides a limit structure, for better assurance when longitudinal sliding appears between boss 1 and recess 2, can not appear horizontal dislocation, need guarantee that boss 1 possesses certain height to avoid lateral shifting's emergence. For example, the height of the boss 1 can be selected to be between 30mm and 50mm, and within the range, the transverse displacement between the boss 1 and the groove 2 can be well avoided, and the quality of the segmented mold can not be influenced.

According to the limiting structure provided by the specific embodiment, the inclination angle of the side surface 4 of the boss 1 can be selected from 3-5 degrees, and the arrangement of the angle can not only well ensure the longitudinal sliding between the boss 1 and the groove 2, but also avoid the transverse misalignment between the boss 1 and the groove when the boss and the groove slide longitudinally.

This embodiment still provides a segmentation forming die, and this segmentation forming die includes foretell limit structure, therefore this segmentation forming die is also the utility model discloses in the scope of right protection.
