Description
Technical field
The present invention is a kind of forming method of the continuous in-orbit drawing tubulation of space flight tubing, specifically thermoplastic composite
Plate unreels, drawing molding and welding process.
Background technique
Tubing is entered the orbit thermoplastic composite transport using rocket in continuous in-orbit drawing equipment, by space manufacture machine
The processing of people's completion product.This method can realize the quick manufacture of pipe structure, save in-orbit storage space, reduce cost, be
The construction of space main facilities lays the foundation, and fills the domestic gaps.The in-orbit continuous drawing process of Thermoplastic Laminates
Unreeling including plate forms and welding process.Wherein, plate passes through preforming tool, plate transition mold and qualitative mould
Shape tubing.The step is molding key, and can decision shape tubing and whether the pipe workpiece quality shaped meets reality
Border demand.If plate direct forming goes out tubing, then deflection is excessive, and obtained tubing is difficult to reach actual requirement, composite wood
Flitch material can not progressive forming go out tubing.
Summary of the invention
The present invention provides a kind of heat for above-mentioned problem present in the in-orbit continuous drawing forming technique of tubing in space
The method of the in-orbit continuous tubulation of plasticity tree composite board.
The present invention is achieved by the following technical solutions, following steps:
Step 1: Thermoplastic Laminates high temperature under the irradiation of infrared lamp unreels, coiled strip under external force by
It gradually flattens, into formative stage；
Step 2: Thermoplastic Laminates pass through pre-molding in high temperature assist formation mold, and it is small that plate starts one
Section forms bending section；
Step 3: thermoplastic composite material board material enters gradual transition after pre-molding under the pulling force effect of external force
Section, plate both ends are gradually drawn close and form overlap joint.
Step 4: in tubing, overlapped that part is welded, and then cools down tubing, fixed shape.According to required pipe length
It is cut.
Preferably, the step 1, specifically: temperature setting will guarantee at material during plastic composite board material unreels
In the state of elastomeric state, guarantee the extensibility of material.Temperature not be arranged the excessively high matrix by material and melt simultaneously.
Preferably, the step 2, specifically: the assist formation mold is approximately half horn shape, i.e. lower die plate material
Upstream end bendability is lower, is approximately straightened condition, and output end bendability is higher after plate forming, is approximately semicircle；Upper mold
Have plate upstream end, output end curvature and lower mold to cooperate.The tune of the shape of the plate upstream end and output end of auxiliary mould
Section all has a great impact to the pipe geometry and quality that shape with control and the control of die length, need to be according to itself
It is required that being adjusted.
Preferably, the step 3, specifically: the Thermoplastic Laminates after pre-molding are fixed in upper/lower die
Continue pultrusion under conditions of motionless and enter progressive molding die, gradually obtains composite material pipe.
Preferably, the step 4: welding stage cooperation setting pipe sleeve prevents occurring rebound phenomenon in welding process.
The invention has the advantages that the present invention utilizes the upper/lower die of special designing, make Thermoplastic Laminates
It is unreeled at high temperature, drawing molding, the continuous in-orbit drawing tube-making process of welding avoids deflection mistake in forming process
Big and reheating energy dissipation, can greatly improve production efficiency, shorten the production cycle, can promote and apply.

Specific embodiment
Elaborate below to the embodiment of the present invention: the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
In a specific embodiment according to the present invention, as shown in Figures 1 to 3, Fig. 1 is multiple for thermoplasticity provided by the invention
The overall schematic of the continuous in-orbit drawing molding tube-making process of condensation material plate, wherein supply 11, guiding 12, heating 13, pultrusion
Molding 14, welding 15, traction 16, cutting 17, main includes unreeling, pultrusion and welding portion；In conjunction with Fig. 2, according to this hair
The Thermoplastic Laminates of bright offer are configured to the in-orbit drawing continuous forming process of tubing, which includes feeding,
Rail is drawn, and 5, weld three major ways.Infrared heating equipment (infrared lamp 4) is used in the feeding process, guarantees heating temperature
Thermoplastic composite is set to be in elastomeric state easy to form.Drawing forming process includes that assistant formation and transition form two portions
Point.The upper/lower die of assist formation mold and some differences (Fig. 3) of traditional mold, lower 3 plate upstream end bendability of mold compared with
It is low, it is approximately straightened condition, output end bendability is higher after plate forming, is approximately semicircle；1 plate upstream end of upper mold with
Output end curvature and lower mold 3 cooperate.The adjusting and control of the shape of the plate upstream end and output end of auxiliary mould, and
