AI Technical Summary

Technical Problem

Existing heat treatment anti-deformation tooling can only be applied to ring parts with the same inner diameter, and cannot meet the multi-size requirements of aero-engine ring parts with multiple varieties and small batches, resulting in wasted production costs and out-of-tolerance for forging dimensions.

Method used

A heat treatment anti-deformation fixture for ring parts with variable outer diameter was designed. By sliding adjustment of the central column and collar, combined with swing and angle control of the support arm, adaptive support for ring parts of different sizes can be achieved. The fixture includes a combination structure of central column, collar and support arm.

Benefits of technology

It enables flexible adjustment of tooling, making it suitable for ring parts of different sizes, reducing production costs and improving the applicability of tooling and the roundness accuracy of forgings.

Abstract

The utility model discloses a heat treatment anti-deformation tool for an annular piece with a variable outer diameter size, which is characterized by comprising a central column 10, a lantern ring 30 and at least eight supporting arms 20, the number of the lantern rings 20 is two, and the lantern rings 20 are arranged at the upper end and the lower end of the central column 10 in a sleeving mode and can slide up and down along the central column 10. Each supporting arm 20 comprises two supporting columns 21, two rocker arms 22 and a supporting baffle 23; one ends of the two supporting columns 21 are fixed to the upper lantern ring and the lower lantern ring respectively, and the other ends of the two supporting columns 21 are clamped in the clamping grooves 24 of the supporting baffles 23 and can slide up and down along the clamping grooves 24. One end of each rocker arm 22 is fixed in the center of the central column 10 and can swing along a fixed point, and the other end of each rocker arm 22 is fixed at the position, close to the supporting baffle 23, of the outer end of the supporting column 21 and can swing along the fixed point. The size of the tool can be adjusted by controlling the lantern ring to drive the supporting arm to slide up and down, and the tool can be suitable for annular pieces of different sizes. The die is mainly used for heat treatment of annular parts.

Description

TECHNICAL FIELD

[0001] The utility model relates to a heat treatment frock, especially, relate to a kind of annular piece heat treatment anti-deformation frock of variable outer diameter size. BACKGROUND

[0002] With the quality improvement requirement of various equipment, titanium alloy solid solution strengthening heat treatment is used more and more widely, compared with traditional titanium alloy annealing heat treatment, solid solution strengthening heat treatment can effectively improve the strength level of forging, but titanium alloy annular forging will occur irregular deformation in solid solution strengthening heat treatment process, resulting in forging size out of tolerance, causing scrap, waste production cost. At present, the heat treatment anti-deformation frock commonly used can only be used for the heat treatment of annular pieces with the same inner diameter size. For the annular pieces of aero-engine, the characteristics of multiple varieties and small batch lead to the need to produce multiple frocks of different sizes to meet the use requirements. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a kind of annular piece heat treatment anti-deformation frock of variable outer diameter size, which can be adjusted according to the inner diameter size of annular piece during use, thereby improving frock efficiency and reducing cost.

[0004] To solve the above technical problems, the annular piece heat treatment anti-deformation frock of variable outer diameter size comprises a center column, a sleeve ring and at least eight support arms. The sleeve ring has two parts, which are respectively sleeved on the upper end and lower end of the center column and can slide up and down along the center column. Each support arm comprises two support columns, two rocker arms and one support baffle. One end of the two support columns is fixed on the upper and lower sleeve rings, respectively, and the other end is clamped on the clamping groove of the support baffle and can slide up and down along the clamping groove. One end of the two rocker arms is fixed on the center of the center column and can swing along the fixed point, and the other end is fixed on the outer end of the support column near the support baffle and can swing along the fixed point.

[0005] In particular, the included angle between the two support arms is ≤45°.

[0006] Compared with the prior art, the utility model has the following advantages:

[0007] The annular piece heat treatment anti-deformation frock of variable outer diameter size can adjust the size of the frock by controlling the sleeve ring to drive the support arm to slide up and down, and can be suitable for annular pieces of different sizes. When the two sleeve rings are close to each other, they can support larger annular pieces; when the two sleeve rings are far away from each other, they can support smaller annular pieces. On the other hand, when the included angle between the two support arms is ≤45°, the roundness of the annular piece can be guaranteed to the maximum. BRIEF DESCRIPTION OF DRAWINGS

[0008] The utility model discloses further in combination with the drawings and specific embodiment makes further detailed description.

[0009] Figure 1 It is the variable outer diameter size's annular piece heat treatment anti-deformation frock structure schematic diagram of the utility model discloses.

[0010] Figure 2 It is the support arm structure schematic diagram of the utility model discloses. Specific embodiment

[0011] The utility model discloses variable outer diameter size's annular piece heat treatment anti-deformation frock, its characterized in that, this frock includes center column 10, sleeve ring 30 and at least 8 support arms 20, sleeve ring 20 has 2, respectively the upper end and lower end of center column 10 are covered, can slide along center column 10 up and down, every support arm 20 includes 2 support column 21, 2 rocker arm 22 and 1 support baffle 23, 2 support column 21 one end is fixed on the upper and lower sleeve ring respectively, the other end is clamped in the clamping groove 24 of support baffle 23 and can slide along clamping groove 24 up and down, 2 rocker arm 22 one end is fixed in the center of center column 10 and can swing along fixed point, the other end is fixed in the outer end of support column 21 and can swing along fixed point near support baffle 23's position.

[0012] Particularly, the included angle between the two support arms is ≤45°.
