Abstract
The present invention relates to a kind of methods deformed when prevent with the heat treatment of U-type groove shaped piece, before band U-type groove shaped piece shove charge, one end of several vertical ribs is welded on to the top of the U-type groove with U-type groove shaped piece, several both ends of rib anyhow are respectively welded on the thin-walled on U-type groove both sides, and U-type groove notch is placed on pallet downward；The lower end of several vertical ribs is withstood on pallet；To carry out high-temperature heat treatment with U-type groove shaped piece and pallet entirety shove charge, will integrally be come out and cooled down with U-type groove shaped piece and pallet after heat treatment, then is whole into furnace tempering, be tempered complete body come out of the stove it is air-cooled.The deformation generated during heat treatment by shaped piece top weight is sustained by vertical rib using the present invention, the deformation that U-type groove both sides thin-walled generates during heat treatment is controlled by rib anyhow, elimination stress processing after avoiding subsequent highly difficult aligning and aligning, manufacturing cost is saved, the manufacturing cycle is shortened.
Description
Technical field
The present invention relates to a kind of methods deformed when prevent with the heat treatment of U-type groove shaped piece.
Background technique
When band U-type groove shaped piece heat treatment, after can only placing downward its U-type groove notch, then it is heat-treated, because U-shaped
Two side wall of slot is thin, and deformation is easy to produce in heat treatment process, there is the body design of a square plate shape at the top of U-type groove, the square plate shape
During heat treatment, the top of U-type groove causes to deform ontology because bearing square plate shape ontology own wt.After deformation, after needing
Elimination stress processing after continuing highly difficult aligning and aligning.Therefore, it is necessary to which inventing one kind can control this kind band U-type groove shaped piece
The method to deform during heat treatment.
Summary of the invention
The purpose of the present invention is be directed to above-mentioned status, it is desirable to provide one kind can solve band U-type groove shaped piece and be heat-treated time-varying
The problem of shape, the prevention for eliminating stress processing after can avoid subsequent highly difficult aligning and aligning is at U-type groove shaped piece heat
The method deformed when reason.
The implementation of the object of the invention is, a method of prevent to deform when being heat-treated with U-type groove shaped piece, with U-shaped
Before 1 shove charge of slot shaped piece, one end of several vertical ribs is welded at the top of the U-type groove with U-type groove shaped piece, several muscle anyhow
Both ends are respectively welded on the thin-walled 7 on U-type groove both sides, and U-type groove notch is placed on pallet downward；Several vertical ribs
Lower end is withstood on pallet；
High-temperature heat treatment will be carried out with U-type groove shaped piece and pallet entirety shove charge, it will be with U-type groove shaped piece after heat treatment
And pallet integrally comes out and cools down, then whole into furnace tempering, be tempered complete body come out of the stove it is air-cooled.
The deformation generated during heat treatment by shaped piece top weight is sustained by vertical rib using the present invention,
The deformation that U-type groove both sides thin-walled generates during heat treatment is controlled by rib anyhow, avoids subsequent highly difficult aligning
And the elimination stress processing after aligning, manufacturing cost is saved, the manufacturing cycle is shortened.
Detailed description of the invention
Fig. 1 is rib arrangement states main view of the invention,
Fig. 2 is rib arrangement states side view of the invention,
Fig. 3 is rib arrangement states bottom view of the invention.
Specific embodiment
One end of several vertical ribs is welded on 6 at the top of the U-type groove with U-type groove shaped piece 1 by the present invention, several muscle anyhow
2 both ends of item are respectively welded on the thin-walled 7 on U-type groove both sides, and the notch of U-type groove 5 is placed in downward on pallet 4；It is several vertical
The lower end of rib is withstood on pallet.
Conventional high-temperature heat treatment will be carried out with U-type groove shaped piece and pallet entirety shove charge, it will be with U-type groove after heat treatment
Shaped piece and pallet integrally come out and cool down, then whole into furnace, carry out conventional tempering, have been tempered, integrally come out of the stove air-cooled.
Specific embodiment is used below.
Referring to Fig.1-3, the band U-type groove shaped piece of the applicant 2.5m long to a U-type groove, high 0.5m, before shove charge, by 4
Diameter is that one end of the vertical rib of 50mm is welded on the top of the U-type groove with U-type groove shaped piece, and 5 diameters of number are 50mm's
Anyhow rib both ends are respectively welded on the thin-walled on U-type groove both sides, and the notch of U-type groove 5 is placed in downward on pallet 4；It is several
The lower end of vertical rib is withstood on pallet.
Conventional high-temperature heat treatment will be carried out with U-type groove shaped piece and pallet entirety shove charge, it will be with U-type groove after heat treatment
Shaped piece and pallet integrally come out and cool down, then whole into furnace, carry out conventional tempering, have been tempered, integrally come out of the stove air-cooled.
Result after heat treatment: before not using the present invention, the deflection after heat treatment in terms of height reaches 8mm~10mm, wide
The deflection of degree aspect reaches 10mm~12mm, is unsatisfactory for technical requirements.After applying the present invention, the deformation after heat treatment in terms of height
Amount is only 2mm~3mm, and deflection 2mm~3mm in terms of width meets technical requirements.
The deformation generated during heat treatment by shaped piece top weight is sustained by vertical rib using the present invention,
The deformation that U-type groove both sides thin-walled generates during heat treatment is controlled by rib anyhow, avoids subsequent highly difficult aligning
And the elimination stress processing after aligning, manufacturing cost is saved, the manufacturing cycle is shortened.
Claims (2)
