Description
Technical field
The present invention relates to a kind of improved hot-forging moulds, belong to electric component field.
Background technology
Plate-shaped parts are the chief components of various industrial processes machineries, their shape and processing and manufacturing quality will
Directly influence the working performance of equipment（Such as the impeller cover of centrifugal blower）.One centrifugal blower can also use multigroup lid sometimes
Disk.Large centrifugal fan is the capital equipment of the industries such as China's metallurgy, oil, chemical industry and pharmacy.At present outside impeller disc boss
The bending forming of the side conical surface is mainly to realize that impeller disc material therefor is mainly stainless steel etc. by the method being machined
Intensity height and resistant material.Using cutting working method, that there are stock utilizations is very low, and subsequent mechanical processing capacity is big, manufacture
The problems such as of high cost and period is long.
A kind of hot forging bending die for the impeller disc being suitble to different diameter of bores is disclosed in the prior art（The patent No.
CN201220295938.7）Solves the above problem.But this molding die in the prior art is in actual use,
Since the outer diameter of lower die guide sleeve is fixed, workpiece may will produce workpiece shaking and fix loosely when in installation to lower die guiding set
Situation affects the precision of work pieces process.
Invention content
In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide a kind of improved hot forgings
Compression mould improves the service life of mold.
In order to solve the above technical problems, the technical solution adopted by the present invention is that, a kind of improved hot-forging mould, by connecting
Axis（1）, lower mold（2）, lower die guide sleeve（3）, upper die guide sleeve（4）And upper mold（5）Composition, the lower mold（2）For cone
Shape, upper mold（5）Interior cavity and lower mold（2）With lower die guide sleeve（3）Shape match, upper mold（5）With upper die guide sleeve
（4）Between coordinated by shoulder, connecting shaft（1）With lower mold（2）With lower die guide sleeve（3）Between be clearance fit；The lower die
Guide sleeve（3）Side wall on be provided with annular groove（6）, annular groove（6）Inside it is provided with workpiece fixation device.
Optimization, above-mentioned improved hot-forging mould, the workpiece fixation device includes several curved support plates（7）, arc
Shape support plate（7）It is uniformly arranged on annular groove（6）, curved support plate（7）Arc opening edge and annular groove（6）Inner wall
Fixed welding.
Optimization, above-mentioned improved hot-forging mould, the curved support plate（7）Quantity be 4 to 8.
Optimization, above-mentioned improved hot-forging mould, the curved support plate（7）Arc opening in the flexible branch of setting
Strut（8）, elastic supporting bar（8）Both ends respectively with annular groove（6）Inner wall, curved support plate（7）Inner wall is fixedly connected.
Optimization, above-mentioned improved hot-forging mould, the lower die guide sleeve（3）And upper die guide sleeve（4）It is replaceable.
Optimization, above-mentioned improved hot-forging mould, the lower die guide sleeve（3）And upper die guide sleeve（4）It is a diameter of a variety of
Specification is suitable for the impeller disc of different diameter of bores.
In the technical solution of the application, workpiece fixation device is increased, when workpiece is socketed on lower die guide sleeve（3）When upper, arc
Shape support plate（7）Flexible deformation occurs, passes through curved support plate（7）Generation flexible deformation after elastic restoring force workpiece is risen
Tightly so that workpiece is fixed on lower die guide sleeve（3）Above and it will not shake.In curved support plate（7）When flexible deformation occurs,
Elastic supporting bar（8）Also flexible deformation can occur, pass through elastic supporting bar（8）Elastic restoring force support arc support plate（7）,
Make curved support plate（7）With the support force bigger of workpiece.
