It is limited.
Thereby, when tubular protective sheath 80 wears, or needs to shape to the steel pipe of different sizes, also may be used
Directly to change.
To sum up, the present invention is mutually combined to form steel pipe shaping mould using upper mould and lower mould, solves in the prior art one
It is not high that intensity easily occurs in the mould of body cast type, the problems such as easily abrasion, so as to also ensure while mould strength is ensured
The precision of steel pipe sizing, and because the mould after improvement is formed by upper mould and lower module are vertical, when certain part appearance in mould
Abrasion, can only replace abrasion upper mould or lower mould without overall replacement, then ensure also to improve just while economy
Profit.
Further, the present invention protects the easy dull die in type-approval process using the higher tubular protective sheath of hardness
Mouthful, so as to avoid mould mouth because abrasion and caused by precision problem, improve can steel pipe shaper service life, and manage
Shape protective case can also be dismantled, when tubular protective sheath wears, or needs to shape to the steel pipe of different sizes,
Can also directly it change.
Embodiments of the invention are the foregoing is only, it is not limited to the scope of patent protection of the present invention.It is any ripe
Alike those skilled in the art is practised, is not being departed from spirit and scope of the invention, the change made and the equivalence replacement of retouching, is still this hair
Bright scope of patent protection.
