Hole pattern steel strip reinforced multiple tube process units
Technical field
The present invention relates to multiple tube process units, more particularly to be hole pattern steel strip reinforced multiple tube process units.
Background technology
It is needed in hole pattern steel strip reinforced multiple tube process units to being carried out from surface cooling sizing from the tubing squeezed out in die head
Reason, reaches that tube surfaces are bright and clean, and circularity and diameter reach standard requirement, is all using directly by tap water from water inlet pressure in the past
In people's aquaporin, but actually in different climatic seasons and different working environments and different tubing specifications, material pair
The requirement of coolant water temperature is different, and water temperature cannot be adjusted, and can not guarantee that the standard of bright and clean tube surfaces, circularity and diameter is wanted
It asks, also previous aquaporin is mutually ganged up, and some places water flowing is more, and some places water flowing is few, or even part anhydrous is arrived
It reaches, tube surfaces inhomogeneous cooling is even, and tubing quality is difficult to ensure, reduces yield rate.
In hole pattern steel strip reinforced multiple tube process units in order to ensure tubing production continuity, it is necessary to before steel belt molding
Installation storage band device, in order to ensure that steel band is accurately curled into cylindrical shape in molding machine, and ensures that its abutment joint is flat
In whole consistent entrance welder, ensureing welding quality, it is desirable to steel band is entered with steady consistent state in molding machine, and
Storage before previous steel belt forming device with device in be not provided with position limiting structure to steel band, cause steel band to be molded entering
Device front left and right is swung, and it is smooth consistent with abutment joint to influence steel belt molding cylinder quality, so as to cause tubing quality decline.
Unreeling machine in hole pattern steel strip reinforced multiple tube process units is first component in production line, and previous unreels
Machine is all that steel band is placed in a core by motor drive rotation, and motor drives core rotation and the subsequent traction of production line
Machine interaction makes steel band run out, and this mode of broadcasting is not perfectly flat steady after so that steel band is gone out unreeling machine, up and down fluctuation and left and right pendulum
It is dynamic, follow-up work is influenced, such as reel forming and welding quality, causes tubing quality decline.
The center line of die head will be consistent with the entire production line center in hole pattern steel strip reinforced multiple tube process units, special
It is not, the tubing steel band in this way produced inside and outside plastics uniform wall thickness consistent with the diameter-setting equipment center line before die head, tubing
Circularity is guaranteed, and the adjustment of hole pattern steel strip reinforced multiple tube process units die head center line at present is to lean on the entire die head of manpower movement
Bearing, time-consuming and laborious also effect is bad, can not be finely adjusted processing, complicated for operation, inefficiency.
