Abstract
The utility model relates to a local non-oxidation heat treatment device which is a cladding body for wrapping the outer surface of a casting workpiece needing heat treatment. The cladding body is made of metal sheets, a shape follow-up iron sheet is manufactured according to the contour of the casting workpiece by the local non-oxidation heat treatment device, so that the casting workpiece is wrapped, the dimension of the casting workpiece cannot be affected by scale generated on the surface of the casting workpiece after heat treatment, annealing requirements are met, the overall dimension of the casting workpiece is ensured, and the device has a high use value.
Description
Technical field
The utility model relates to a kind of be used to preventing foundry goods excessively oxidated thermal treatment unit when the thermal treatment.
Background technology
In order to improve the mechanical characteristics of foundry goods, after the cast casting moulding, need to give corresponding thermal treatment.In, all unavoidably produce one deck oxide skin after the large-scale steel-casting thermal treatment, when needing to heat-treat again after some foundry goods roughing, because coming off of oxide skin is easy to make foundry goods physical dimension less than normal.
Summary of the invention
The purpose of this utility model is to provide a kind of local non-oxidation thermal treatment unit, this part non-oxidation thermal treatment unit can make the heat treating castings rear surface can not affect casting dimension because producing oxide skin, both satisfy the annealing requirement, guaranteed again foundry goods physical dimension.
The technical solution of the utility model is: a kind of local non-oxidation thermal treatment unit, and this device is a kind of cladding be used to being wrapped in foundry goods outer surface of workpiece to be heated, described cladding is made by metal sheet.
In order to draw materials conveniently, described metal sheet can adopt iron sheet.
Because most foundry goods all is circular, according to the specification of foundry goods, can be prefabricated in advance, satisfactory circular cover body is used as cladding.
For the foundry goods of some more complicated, adopt simple cover body can't cover its surface fully, the interval that foundry goods need to be divided into several simple appearance profiles makes cladding.Therefore, described cladding can be to be combined by a plurality of annular solids and cover body.
The utility model has the advantage of: this part non-oxidation thermal treatment unit is to make the conformal iron sheet according to the foundry goods profile, to wrap foundry goods, makes the heat treating castings rear surface can not affect casting dimension because producing oxide skin; Both satisfy the annealing requirement, guaranteed again foundry goods physical dimension; Has higher use value.
Description of drawings
Fig. 1 is the structural representation of the local non-oxidation thermal treatment unit among the embodiment.
Label declaration: the stair-stepping cover body of 1-circular cover body 2-.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperation accompanying drawing be described in detail below, but the utility model are not limited to this.
Referring to attached Fig. 1 and 2, local non-oxidation thermal treatment unit of the present utility model, this device is a kind of cladding be used to being wrapped in foundry goods outer surface of workpiece to be heated, described cladding is made by metal sheet.
In order to draw materials conveniently, described metal sheet can adopt iron sheet.
Because most foundry goods all is circular, according to the specification of foundry goods, can be prefabricated in advance, satisfactory circular cover body 1 is used as cladding.
For the foundry goods of some more complicated, adopt simple cover body can't cover its surface fully, the interval that foundry goods need to be divided into several simple appearance profiles makes cladding.Therefore, described cladding can be to be combined by a plurality of annular solids and cover body, can also be stair-stepping cover body 2 certainly.
Although the utility model discloses as above with embodiment; so it is not to limit the utility model; anyly have the knack of this skill person; within not breaking away from spirit and scope of the present utility model; when being used for a variety of modifications and variations, therefore protection domain of the present utility model is as the criterion when looking accompanying the claim person of defining.
