Example 1
A spinning die with an extending movable block ring is used on spinning equipment and comprises a top die pressing plate 1, an ejection block 2, a body die 3, an ejection connecting block 4, a movable block ring 5, an ejection connecting rod 6, an ejection rod pressing block 7 and a machine table connecting flange 8. The top die pressing plate 1 is arranged above the body die 3, the top die pressing plate 1 and the body die 3 are matched for fixing a spinning casting, and after the spinning casting is fixed by the top die pressing plate 1 and the body die 3, the spinning casting can do rotary motion along with the spinning die. The spin casting in this embodiment is a hub. The spin casting includes a mounting face 9, spokes 10 and a rim 12.
This phantom 3 fixed connection is in board flange 8 top, and ejecting connecting rod 6 is established in the central axis department of this phantom 3, can slide from top to bottom along this phantom 3. The bottom of the ejection connecting rod 6 extends into the machine table connecting flange 8, an ejection rod pressing block 7 is fixedly mounted at the bottom of the ejection connecting rod 6, and the top of the ejection connecting rod 6 penetrates through the body model 3 and extends to the inner space of the body model 3.
The ejection connecting rod 6 is fixedly provided with an ejection connecting block 4, and the tops of the ejection connecting block 4 and the ejection connecting rod 6 are mutually clamped and fixed through bolts. The ejecting connecting blocks 4 are uniformly distributed on the radial section of the inner space of the body die 3 by taking the central axis of the body die 3 as the center of a circle.
The ejection block 2 is arranged on the upper edge of the inner space of the body mould 3, and the ejection block 2 is fixedly connected above the ejection connecting block 4 through a bolt. The invention can be fixed not only by bolts but also by bolts, and any mode capable of fixedly connecting the ejection block 2 and the ejection connecting block 4 is within the protection scope of the invention. The outer surface of the ejection block 2 is matched with the upper edge of the inner surface of the body die 3; the upper surface of the ejection block 2 is matched with the back surface of a spoke 10 of the spinning casting in a fitting manner, and the upper surface of the ejection block 2 keeps a distance with the mounting surface 9 of the spinning casting; the inner surface of the ejection block 2 is kept at a distance from the spokes 10 and the mounting surface 9 of the spinning casting. The structure design ensures that the acting force is uniformly distributed on the spinning casting when the spinning casting is demolded, thereby preventing the occurrence of demolding locking. The ejection block 2 is provided with an annular inner ring protruding out of the bottom surface, and the ejection connecting block 4 is clamped between the body mould 3 and the inner ring, so that the ejection connecting block 4 and the ejection block 2 are connected more firmly.
After the spinning is finished, the oil cylinder enables the ejection connecting rod 6 to slide upwards, and the ejection block 2 is driven by the ejection connecting block 4 to eject upwards and is far away from the body mould 3. Because the ejection blocks 2 are uniformly distributed at the circumferential edge position of the body die 3, stress is uniformly distributed on the spokes 10, and stress is prevented from being concentrated at the central position of the spinning casting, so that the spinning casting is easier to demould, and the production efficiency is improved. The ejector block 2 of the present invention can be adjusted according to the curvature of the spokes 10. When spinning castings of different models need to be matched, only one small part, namely the ejection block 2, needs to be replaced, and the whole die change is not needed, so that the development cost of the die is greatly reduced, and the die change efficiency is improved.
The outer side of the lower edge of the body mould 3 is provided with a movable block ring 5. The movable block ring 5 is fixed on the body module 3 through bolts or bolts and the like.
When in use, the outer wall of the body mould 3 and the inner wall of the rim 12 of the spinning casting are mutually butted. In the same horizontal position, the diameter of the outer wall of the body mould 3 is slightly smaller than or equal to that of the inner wall of the rim 12, so that the two can just keep a mutual contact state.
The loose piece ring 5 includes a connecting portion and an installation portion provided below the connecting portion.
The outer wall of the connection portion and the inner wall of the rim 12 are adapted to fit. When spinning castings with different heights need to be spun, only a proper loose piece ring needs to be selected according to the length of the rim 12, the back-and-forth transfer field is reduced, the production of products with different models can be realized by directly replacing the loose piece ring, and the production cost of the die is reduced.
The installation part of the movable block ring 5 is provided with a key groove 11, so that the mould can be conveniently hoisted.
Example 2
A spinning die with an extended loose piece ring, which is different from embodiment 1 in that: the ejection connecting block 4 is not provided, and the ejection block 2 is directly connected with the ejection connecting rod 6.
The upper surface of the ejection block 2 is matched with the curvature of the spoke 10, and the lower surface of the ejection block 2 is connected with the top of the ejection connecting rod 6, wherein the ejection block and the top of the ejection connecting rod are fixedly connected, and the ejection block and the top of the ejection connecting rod can be bolts or any structural mode capable of fixedly connecting the ejection block and the top of the ejection connecting rod.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
