Abstract
The present invention provides a kind of new core localization method, the method is except reducing freely being outside one's consideration for regulation, using deflection and torsion into this characteristic of positive correlation, in the case where core fixed mount is certain, different torsion combinations have corresponded to different core positions, so as to increased torque-indicating wrench for the quantitative torsion determined used by bolt, control will be more accurate.And due to being that torque-indicating wrench record will be very convenient accurate, the record for just completing core position is combined by record location bolt torsion.The core positioning order be, core is fitted with core fixed mount first, being accurately positioned for core fixed mount and mould is completed with core, then the positioning of core is completed with the core fixed mount having good positioning, using the torsion of each bolt of torque-indicating wrench precise control so as to complete being accurately positioned for core in position fixing process, and the torsion combination of record location bolt, to there is reinforcing material to position reduction through the core after mould.
Description
Technical field
The present invention relates to a kind of pultrusion composite materials rectangular tube core localization method.
Background technology
Pultrusion composite materials rectangular tube using outer cavity mould and central core die combination mode, the concentricity of core and external mold,
The stability of core decides the performance parameters such as the linearity of rectangular tube, thickness evenness.This just to core positioning propose compared with
Requirement high.Existing core positioning method, by the way that to core, four direction carries out position constraint with bolt up and down, adjustment
When the free degree it is excessive, waste time and energy and can also be interfered with each other to factor, cause low precision and time-consuming, laborious.Furthermore, core positioning
After generally require to remove core, just be reattached to core on core fixed mount through after mould by reinforced partly material,
Traditional positioning method is difficult core position accurate reproduction.
The content of the invention
It is an object of the invention to provide a kind of molded through pultrusion of composite material rectangular tube core localization method, can be preferable
Ensure that one-time positioning is accurate, positioning time shortens.
The present invention solve its technical problem concrete scheme be：
A kind of molded through pultrusion of composite material rectangular tube core localization method, first screws on core fixed mount setting on mould
Bolt is not screwed；By core through mould, core fixed mount until at core positioning, core head and core fixed mount frame end
Portion is concordant；
Core location nut is screwed make core two orthogonal faces be close to core fixed mount end L-type position
Plate, is just close to；
Adjusting the position of core fixed mount makes core be in die cavity center, and the front-end and back-end of die cavity, test are inserted using cushion block
The gap of core and the wall of die cavity four, gap is unanimously core and is located at die cavity center；
Core bolt is slowly screwed using torque spanner, torsion, record is read, then core bolt is unscrewed, by core
One section of mould pumpback, then core is moved at core positioning, core head is concordant with core fixed mount end, uses torque spanner
Tightening core location nut makes core be located at die cavity center and read torsion, records；Core bolt is unscrewed, core is extracted out；
Entry, reinforcing material is passed through into die cavity；Data when core location nut is adjusted by core after the completion of entrying tighten spiral shell
Mother, then connects core mold fixing plate, completes core position fixing process.
Compared with prior art, the present invention positions about original four sides with bolt on the basis of original positioning method
The mode of beam is changed to be fitted with core with L-type block, in addition the both sides elastic positioning of bolt.
The method is freely outside one's consideration except reduction regulation, using deflection and torsion into this characteristic of positive correlation, in core
In the case that fixed mount is certain, different torsion combinations have corresponded to different core positions, so as to increased torque-indicating wrench
For the quantitative torsion determined used by bolt, control will be more accurate.And due to being that torque-indicating wrench record will
It is very convenient accurate, the record for just completing core position is combined by record location bolt torsion.
Positioning core by positioning side's method can be accurate by positioning step, one-time positioning, and positioning time shorten to originally
1/3, and locating effect is more accurate, and the linearity and thickness evenness of the rectangular tube made by the localization method are had
Improve.
Brief description of the drawings
Fig. 1 is core positioning schematic diagram of the invention.
Fig. 2 is core positioning tool profile one of the invention.
Fig. 3 is core positioning tool profile two of the invention.
Specific embodiment
It is described in further detail to of the invention below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
The embodiment.
A kind of molded through pultrusion of composite material rectangular tube core localization method, is arranged on mould 1 by core fixed mount 3 first
On, bolt of screwing on is not screwed；By core 4 through mould 1, core fixed mount 3 until at core positioning, the head of core 4 and core
The frame end portion of mould fixed mount 3 is concordant；
Core location nut 5 is screwed to be made two orthogonal faces of core 4 be close to the L-type of the end of core fixed mount 3 to determine
Position plate 7, is just close to；
The position of adjustment core fixed mount 3 makes core 4 be in die cavity center, and the front-end and back-end of die cavity are inserted using cushion block 2, surveys
The gap of examination core and the wall of die cavity four, gap is unanimously core and is located at die cavity center；
Core bolt 5 is slowly screwed using torque spanner, torsion, record is read, then core bolt 5 is unscrewed, will
One section of 4 pumpback of core, then core 4 is moved at core positioning, the head of core 4 is concordant with the end of core fixed mount 3, uses torsion
Torque wrench tightens core location nut 5 makes core 4 be located at die cavity center and read torsion, records；Core bolt 5 is unscrewed,
Extract core 4 out；Entry, reinforcing material is passed through into die cavity；Data when core location nut 5 is adjusted by core after the completion of entrying
Nut is tightened, core mold fixing plate 6 is then connected, core position fixing process is completed.
