Abstract
The present invention relates to casting technology field, specially a kind of elevator machine cylinder shrink rule cun control method.When the elevator machine cylinder is the elevator machine cylinder using material trademark QT400-15, axial reduced scale 6/1000ths, radial reduced scale 8/1000ths.When the elevator machine cylinder is the elevator machine cylinder using material trademark QT450-12, axial reduced scale 8/1000ths, radial reduced scale 8/1000ths.When the elevator machine cylinder is the elevator machine cylinder using material trademark QT500-7, axial reduced scale 10/1000ths, radial reduced scale 10/1000ths.The present invention is directed to this casting with more rope grooves of elevator machine cylinder, the present invention is according to the special construction and unlike material of its more groove, carry out differentiated reduced scale, so that the product size standard being poured in turn using mold made from this method, expanding with heat and contract with cold in casting process has been well adapted to, its influence is effectively avoided.
Description
Technical field
The present invention relates to casting technology field, specially a kind of elevator machine cylinder shrink rule cun control method.
Background technique
In elevator machine cylinder casting process, it necessarily will appear and expand with heat and contract with cold, finished product and die size be not after leading to casting
Unanimously, if according to stock size make mold, obtained cast product do not meet product size requirement, for elevator machine cylinder this
Kind has the casting of many grooves, does not discover how to carry out size control when casting more groove elevator machine cylinders in the prior art
System, therefore study a kind of method that can be casted into the control of row accurate size to elevator machine cylinder and be very important.
Summary of the invention
In view of the defect of the prior art, the present invention proposes a kind of elevator machine cylinder shrink rule cun control method, size control
System is accurate, guarantees that final products are of the required size.
In order to achieve the above objectives, the technical scheme adopted by the invention is that a kind of elevator machine cylinder shrink rule cun controlling party
Method, when the elevator machine cylinder is the elevator machine cylinder using material trademark QT400-15, mold axial direction reduced scale 6/1000ths, mould
Has radial reduced scale 8/1000ths.
Further, described rope end will have correction amount close to first groove of flange, and correction amount adds 1.5mm, groove circle
It slips over and crosses.
Further, it is laid with chill at flange drilling, prevents drill hole shrinkage porosite.
A kind of elevator machine cylinder shrink rule cun control method, the elevator machine cylinder are using material trademark QT450-12's
When elevator machine cylinder, mold axial direction reduced scale 8/1000ths, mold radial direction reduced scale 8/1000ths.
Further, described rope end will have correction amount close to first groove of flange, and correction amount is to add 1.5 mm, groove
Rounding off.
Further, it is laid with chill at the flange drilling, prevents drill hole shrinkage porosite.
A kind of elevator machine cylinder shrink rule cun control method, the elevator machine cylinder are using material trademark QT500-7's
When elevator machine cylinder, mold axial direction reduced scale 10/1000ths, mold radial direction reduced scale 10/1000ths.
Further, described rope end will have correction amount close to first groove of flange, and correction amount is plus 3mm, groove are round
It slips over and crosses.
Further, it is laid with chill at the flange drilling, prevents drill hole shrinkage porosite.
Beneficial effects of the present invention：For this casting with more rope grooves of elevator machine cylinder, the present invention is according to its more ditch
The special construction and unlike material of slot carry out differentiated reduced scale, so that using mold made from this method and then be poured
The product size standard arrived, has well adapted to expanding with heat and contract with cold in casting process, effectively avoids its influence.
