Abstract
The invention relates to a heat treatment method-clamp method for a straight protection plate of a high cast iron shot blasting machine. The heat treatment method-clamp method specifically comprises the steps that the total thickness of the straight protection plate is 20 mm, and four corners and the middle of the long side are underlaid through stainless steel strips of 20*60; and seven layers to eight layers can be knocked, and a clamp is used for clamping the four corners and the middle to put the long side on a quenching hand disc to be heated. In the heating process, small bending during casting is straightened, forced strengthening of a mechanic part during quenching is ensured, and the good effect is achieved.
Description
Technical field
The present invention relates to Field of Heat-treatment, specifically, is the heat treating method-fixture method of the straight backplate of a kind of high cast iron shot-blasting machine.
Background technology
Grow because workpiece is thin, therefore especially very easily deform in thermal treatment in casting, warpage, because rich chromium cast iron fragility is large, can not straightening under normal temperature, can only the nature straightening when high temperature.We adopt lifting heating, and the method for lifting chilling, can solve the problem of distortion preferably, but can not solve the very high problem of hardness, the problem how solving distortion in the tough damp fire of oil becomes a great problem.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the heat treating method-fixture method of the straight backplate of a kind of high cast iron shot-blasting machine is provided.
For achieving the above object, the invention provides following technical scheme:
Straight backplate total thickness 20mm, paves corner, long limit and centre with 20x60 stainless steel strip, can knock 7-8 layer down, is then placed on quenching setting stick with clamp corner and centre and heats.
Compared with prior art, positively effect of the present invention is:
The problem of distortion can be solved preferably, the problem that hardness is very high and how to solve the problem of distortion in the tough damp fire of oil.
Accompanying drawing explanation
Fig. 1 is the heat treating method-fixture method figure of the straight backplate of a kind of high cast iron shot-blasting machine.
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Concrete grammar is:
Straight backplate total thickness 20mm, paves corner, long limit and centre with 20x60 stainless steel strip, can knock 7-8 layer down, is then placed on quenching setting stick with clamp corner and centre and heats.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
