Technical Field

[0001] The utility model relates to a forging tooling for a Z-shaped ring part, belonging to the technical field of forging tooling for aviation forgings. Background Technique

[0002] Forging is one of the important methods of metal plastic processing. Its main purpose is to form metal and improve the mechanical properties and internal structure of metal, etc. And forging production has high production efficiency and great flexibility, and is widely used in the production fields of forgings of various shapes, especially in the production process of various precision forgings.

[0003] As Figure 1 shown, it is a typical Z-shaped forging. If the conventional free forging method is used to produce such forgings, due to the low precision of free forging, relatively more metal materials need to be invested, and the cost of metal materials for aviation forgings is relatively high, so it will lead to an increase in production cost, and the final formed size deviation of the forging is relatively large and the surface quality is relatively poor. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is: to provide a forging tooling for a Z-shaped ring part to solve the technical problems existing in the above-mentioned prior art.

[0005] The technical solution adopted by the utility model is: a forging tooling for a Z-shaped ring part, including an upper sleeve ring, a lower sleeve ring and a guiding spacer block. The upper end of the lower sleeve ring matches the shape and size of the outer side wall of the Z-shaped forging, the lower end of the upper sleeve ring matches the shape and size of the top of the Z-shaped forging, the guiding spacer block is an inverted T-shaped column, the outer periphery of the lower end of the guiding spacer block matches the shape and size of the inner side wall of the Z-shaped forging, the upper sleeve ring is sleeved on the outer periphery of the upper end of the guiding spacer block, and the upper part size of the guiding spacer block matches the size of the upper sleeve ring.

[0006] Preferably, the lower end of the lower sleeve ring is flush with the lower end of the guiding spacer block.

[0007] Preferably, the height of the guiding spacer block is equal to the sum of the height of the upper sleeve ring and the height of the lower sleeve ring.

[0008] Preferably, the outer diameter of the upper sleeve ring is larger than the maximum outer diameter of the Z-shaped forging, and the outer diameter of the lower sleeve ring is greater than or equal to the outer diameter of the upper sleeve ring.

[0009] Advantages of the utility model: Compared with the prior art, the utility model designs a set of special forging tooling for Z-shaped forgings, solves the problems of low production efficiency and poor product quality of Z-shaped forgings caused by the open-die forging method, and can be flexibly adjusted according to the size and shape of the product, solves the problems of poor quality, more material waste and low production efficiency of such Z-shaped forgings, saves production costs, improves operation convenience and production efficiency. Description of the Drawings

[0010] Figure 1 It is a cross-sectional view of a Z-shaped forging.

[0011] Figure 2 It is a cross-sectional view of the overall structure of the utility model.

[0012] The reference numerals in the accompanying drawings of the specification include: upper collar 1, lower collar 2, guiding spacer 3, and ring blank 4. Detailed Embodiment

[0013] The following further introduces the utility model in conjunction with the accompanying drawings and specific embodiments.

[0014] Embodiment 1:

[0015] A forging tooling for a Z-shaped ring, as Figure 2 shown, includes an upper collar 1, a lower collar 2 and a guiding spacer 3. The upper end of the lower collar 2 matches the shape and size of the outer side wall of the Z-shaped forging. The lower end of the upper collar 1 matches the shape and size of the top of the Z-shaped forging. The guiding spacer 3 is in the shape of an inverted T-shaped column, and the outer periphery of the lower end of the guiding spacer 3 matches the shape and size of the inner side wall of the Z-shaped forging. The lower end of the lower collar 2 is flush with the lower end of the guiding spacer 3. The upper collar 1 is sleeved on the outer periphery of the upper end of the guiding spacer 3, and the upper part size of the guiding spacer 3 matches the size of the upper collar 1; the height of the guiding spacer 3 is equal to the sum of the height of the upper collar 1 and the height of the lower collar 2; the outer diameter of the upper collar 1 is larger than the maximum outer diameter of the Z-shaped forging, and the outer diameter of the lower collar 2 is larger than the outer diameter of the upper collar 1.

[0016] When in use, place the lower collar 2 and the guiding spacer 3 on the lower anvil surface of the hydraulic press, then place the ring blank 4 between the lower collar 2 and the guiding spacer 3, and then sleeve the upper collar 1 on the guiding spacer 3, and use the hydraulic press to press the upper collar 1 downward until the upper end of the upper collar 1 is flush with the upper end of the guiding spacer 3.

[0017] The lower parts of the upper collar 1, the lower collar 2 and the guiding spacer 3 are directly in contact with the blank to be forged and formed. The upper part of the guiding spacer 3 plays a role in guiding the upper collar 1 and improves the dimensional accuracy of the formed forging; greatly improves the forming quality of such "Z"-shaped forgings, also saves more raw material input, and improves economic benefits.

[0018] In practical applications, the shape and size of the upper collar 1, the lower collar 2 and the guiding cushion block 3 can be adjusted accordingly according to the shape and size of the Z-shaped forging.

[0019] As mentioned above, the above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
