Abstract
The invention discloses a quenching rack suitable for controlling heat treatment quenching deformation of a seal head, and relates to the technical field of seal head-type part machining. The quenching rack comprises a main frame; the seal head is located in the main frame; the main frame is of a truss type steel structure; the inner surface of a mouth part of the seal head is provided with an expansion ring; the outer surface of the mouth part of the seal head is provided with an adjustable hoop; the top part of the seal head is also provided with a hold-down plate and a hold-down substrate corresponding to the hold-down plate. The problem that the quenching deformation of seal head-type parts in a nitrate furnace is excessive is solved by the quenching rack disclosed by the invention; according to the quenching rack disclosed by the invention, by enhancing integral rigidity of a fixture structure, rigidity is reasonable in distribution, and the parts are constrained; overall deformation of the parts during quenching is controllable by an anti-deformation control measure.
Description
Technical field
The present invention relates to end socket class part processing technique field, particularly relate to a kind of quenching frame being applicable to control the distortion of end socket heat-treatment quenching.
Background technology
End socket connects great circle arc by transition small arc-shaped and straight-line segment forms, its typical structure as shown in Figure 1, material selected by end socket is aluminium alloy LD10 M, and blank thickness is 26mm, and it is formed by the great circle arc connection of the small arc-shaped of the long straight-line segment of 40mm, R213mm and R1238mm.The wall thickness that in design requirements part, profile and theoretical profile deviation are not more than 3mm, mouth diameters is Φ 1756+1-2mm, part
mm, final materials behavior is quenching+artificial aging, and part mouth diameters is comparatively large, is typical large thick-wall aluminum alloy part.And part needs quenching heat treatment to improve intensity and over-all properties.
Factory adopts nitrate groove to carry out end socket quenching heat treatment, and part vertically enters to quench in tank liquor and water coolant.Therefore, it is serious that moment sharply cold and hot impact makes oral area be out of shape, and form ellipticity, meanwhile, oral area gross distortion makes transition small arc-shaped profile that irregular distortion occur, and part height size also changes.Thus the frock clamp be out of shape when needing for controlling end socket thermal treatment.
Summary of the invention
Object of the present invention is just to provide the quenching frame being applicable to control the distortion of end socket heat-treatment quenching, to solve the problem.
To achieve these goals, the technical solution used in the present invention is such: a kind of quenching frame being applicable to the distortion of control end socket heat-treatment quenching, comprise main frame, end socket is positioned at described main frame, described main frame adopts truss type steel structure, end socket oral area internal surface is provided with packing, and end socket oral area outside surface is provided with adjustable hoop, is also provided with compression plate and the compression pedestal corresponding with described compression plate at end socket top.
As preferred technical scheme: described compression pedestal adopts trussed-beam steel beam.
As preferred technical scheme: be also provided with at least one reinforcing structure.
Compared with prior art, the invention has the advantages that:
1) the present invention adopts the outer hooping structure of inner support to control the oral area distortion of end socket, effectively can control hot environment lower cover oral area roundness deformation;
2) the present invention is strengthened by local rigidity, and this is minimum in High Temperature Furnaces Heating Apparatus internal strain to make quenching frame;
3) the present invention effectively controls the height of part under hot environment, thus controls profile quality.
Accompanying drawing explanation
Fig. 1 is the typical structure of end socket;
Fig. 2 is the structural representation of quenching frame of the present invention;
Fig. 3 is the A-A sectional view of Fig. 2.
In figure: 1, main frame; 2, end socket; 3, packing; 4, adjustable hoop; 5, compression plate; 6, pedestal is compressed; 7, reinforcing structure.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment:
See Fig. 2-3, a kind of quenching frame being applicable to the distortion of control end socket heat-treatment quenching, comprise main frame 1, end socket 2 is positioned at described main frame 1, described main frame 1 adopts truss type steel structure, by increasing the rigidity of fixture and quenching frame structure, effectively suppresses the distortion of part in heat treatment process, end socket 2 oral area internal surface is provided with packing 3, and packing 3 is for controlling end socket 2 to internal strain; End socket 2 oral area outside surface is provided with adjustable hoop 4, and adjustable hoop 4 can ensure circularity at the bottom of three cores of end socket, controls the distortion that it is oval trend; Compression plate 5 and the compression pedestal 6 corresponding with described compression plate 5 is also provided with at end socket 2 top; Compress pedestal 6 and adopt trussed-beam steel beam, according to FEM Numerical Simulation, be also provided with several reinforcing structure 7.
The foregoing is only preferred embodiment of the present invention, not in order to limit this present invention, all do within this spirit of the present invention and principle any amendment, equivalently to replace and improvement etc., all should be included within this protection scope of the present invention.
Claims (3)
