Abstract
The utility model provides a multi-roller mould for a production line of aluminum-plastic composite pipes. The multi-roller mould for a production line of aluminum-plastic composite pipes is provided with at least two mould rollers, the mould pressing surface of each mould roller together forms a fully closed mould opening which is matched with the section periphery of an aluminum-plastic composite pipe. The multi-roller mould for a production line of aluminum-plastic composite pipes not only can dispose an aluminum pipe and a plastic pipe in a tight bond mode, but also has very long service life.
Description
The utility model relates to a kind of multiple roll mould, especially for the multiple roll mould on the production line of aluminum plastic.
PAP is a kind of building material, and its purposes more and more widely.The manufacturing of PAP is that gluing coats aluminum pipe outside the plastic tube of forming, injection moulding outer tube again, thus form PAP.PAP can have the plastic layer and the aluminium lamination of multilayer.In when producing PAP, requiring outside plastic tube and the interior plastic tube aluminum pipe combine closely, therefore, when the coating aluminum pipe, need carry out the processing that aluminum pipe and plastic tube are combined closely.Present processing method is for adopting the method for nylon jacket undergauge, and the multiple tube that is about to have coated aluminum pipe is pulled through in the trepanning of nylon jacket, and multiple tube is subjected to the circumferential extruding of trepanning inwall in the trepanning of nylon jacket, thereby aluminum pipe and plastic tube are combined closely.But when multiple tube passed the trepanning of nylon jacket, there were very large friction in multiple tube and trepanning, and therefore, the life-span of nylon jacket is very short, and the multiple tube of approximately handling the 1-2 km just needs to change.In addition, when changing cover, the production line of producing multiple tube need be stopped, cut off multiple tube, change.Therefore, reduced production efficiency, the production cost of multiple tube is increased greatly.
The purpose of this utility model is to provide a kind of multiple roll mould that is used on the production line of aluminum plastic, the processing of not only aluminum pipe and plastic tube can being combined closely of this multiple roll mould, and also its life-span is long a lot of with respect to the life-span of nylon jacket.
The purpose of this utility model is achieved in that a kind of multiple roll mould that is used on the production line of aluminum plastic, it is characterized in that: this multiple roll mould is provided with two mould rollers at least, and the mold pressing surface assembly group of each mould roller forms the totally enclosed die orifice that cooperates with the cross section peripheral shape of the PAP of injection moulding outer tube not.
Described cooperation is an interference fit, and this multiple roll mould is when the extruded aluminium plastic composite, and PAP is subjected to the circumferential extruding of multiple roll mould, and the aluminum pipe of PAP produces undergauge and sizing, thereby aluminum pipe and plastic tube are combined closely.
The cross section peripheral shape of described PAP is circular, square, oval, polygon or abnormity.
There is not the gap between the assembly set of contact face of described two adjacent mould rollers arbitrarily.Near one section small end face that is provided with projection separately of mold pressing surface, two small end faces do not have the gap contact on the assembly set of contact face of described two adjacent mould rollers arbitrarily.
Described mould roller rolls and is supported on the supporter.The centre of gyration of described mould roller is provided with bearing, be equipped with in the bearing axle be supported on the supporter, the centre of gyration of perhaps described mould roller is installed with axle, the axle two ends by bearings on supporter.The Support Position of described supporter is adjustable.
The outer field hardness of 1/3 thickness is identical in the described mould roller, is not less than HRC50, is preferably more than the HRC60.
The multiple roll mould that is used on the production line of aluminum plastic of the present utility model has following usefulness:
1, uses the multiple roll mould that is used on the production line of aluminum plastic of the present utility model, the processing of not only aluminum pipe and plastic tube can being combined closely of this multiple roll mould, and between mould roller and the PAP rolling friction, it or not the sliding friction between nylon jacket and the multiple tube, so its life-span is long with respect to the life-span of nylon jacket, and every group of multiple roll mould can be handled more than 10 myriametres.
2, the outer field hardness of 1/3 thickness is not less than HRC50 in the described mould roller.After these multiple roll mould wearing and tearing, because hardness is identical in the outer certain thickness of mould roller, after can processing again the mold pressing surface of multiple roll mould, continue to use, reduced the manufacturing cost of multiple roll mould.
3, described mould roller rolls and is supported on the supporter, and the Support Position of described supporter is adjustable.Therefore, during each mould roller, can adjust the position relation between each mould roller, not have the gap thereby can reach between the assembly set of contact face of adjacent two mould rollers in assembling.And, after processing mold pressing surface again after the wearing and tearing of mould roller, adjust supporter, make the mold pressing surface of each mould roller piece together the totally enclosed die orifice of composition again, thereby can continue to use.
