Description
Technical field
The present invention relates to the more changing device of metallurgical equipment moulds of industrial equipment, in particular for the die holder on pipe end thickening machine
More changing device.
Background technology
When designing pipe end thickening machine mould, single die holder is designed with for installing life in order to save operation cost
Mould required for production, in production because the difference of steel pipe specification is frequently necessary to more mold exchange.The maximum produced when thickening machine
When specification steel pipe and larger minimum gauge diameter difference, if carrying out installation mold using same die holder, small dimension steel can be caused
The mold weight of pipe is too big and wastes expensive mold materials, now, and design different size die holder can not only reduce mould
Appearance and size, and more mold exchange is also more convenient.Every thickening machine can thicken the steel pipe of different size, change production rule
It is accomplished by changing the die holder of suitable different size steel pipe during lattice.
The weight of die holder in itself is very heavy, and the manpower before will seem by the die change system of overhead traveling crane more wastes time and energy
And it is dangerous very high, or even mold changing can not be completed.Therefore, when different size pipe end thickeies, replacing is provided with different size
The die holder of mould is exactly a comparatively not only economic but also time saving mold changing scheme.
