Second step, extracts spiral-plate and is placed on lower platen centre in order；
3rd step, enters grinding inclined-plane veneer directed downwardly from pallet side is gone out, is overlapped on the veneer of another inclined-plane upward；
4th step, starts top board hot pressing；
5th step, reaches setting time top board and rises solidification by cement completion automatically, open press, take out splice plate by specification point
Do not pile up；
6th step, is piled up, and descends sanction plate process.
It is preferred that, the specific process of the first step is：Veneer after being ground carries out specification screening and then carries out matching board,
Grinding is then subjected to block pattern row pattern up after plate face carries out gluing, gluing.
It is preferred that, the specific process of second step is：All veneers that need to be integrated are entered according to the glued order of regulation
Row is piled up, and the veneer order piled up is proofreaded after piling up.
It is preferred that, the specific process of the 3rd step is：Grinding surface veneer directed downwardly is inserted from the opposite side of pallet, with first
Face-up veneer progress is ground in step staggered, and the gluing between plate face staggeredly.
It is preferred that, the specific process of the 4th step is：After integrating staggeredly, the upper pressure that the veneer of gluing passes through hot press each other
Plate carries out hot pressing, and veneer is carried out into justifying pressing by hot glue and hot pressing, and the time of hot pressing is carried out according to the width of plate face
Can be different, when plate is wider than 1570 millimeters, hot pressing time is more than 65 seconds, and when plate is wide is less than 1200 millimeters, hot pressing time is
45 seconds, and the pressure value of whole hot press is more than 0.3MPa, hot pressing temperature is between 180 ~ 199 DEG C.
It is preferred that, the specific process of the 5th step is：After reaching between compacting, hot press is opened, the sheet material after hot pressing is carried out
Check, if any the position for not being pressed gluing, its dry glue is purged, repeated the above steps, if not having after whole sheet material compacting
It is defective to be piled up with installation specification.
Compared with prior art, the beneficial effects of the invention are as follows；The production of mitered electrical laminated wood is in common electrical lamination
Developed on the basis of wood production.Technique is to be partially adjusted.By using narrow boards hot pressing unit, the edge to veneer is entered
Row grinding, then by processes such as gluing hot pressing, realize whole change of veneer, produced after gluing, assembly, hot press HTHP
Go out high-quality mitered electrical laminated wood.
Embodiment
Below in conjunction with embodiment, the present invention is described further, but protection scope of the present invention is not limited to this.
Hot pressing mitered technique in a kind of mitered electrical laminated wood production process, it is characterised in that including following technique stream
Journey：
The first step, the brush coating that matching board is completed is ground veneer, and grinding inclined-plane is piled up on plate workbench is entered upward；
Second step, extracts spiral-plate and is placed on lower platen centre in order；
3rd step, enters grinding inclined-plane veneer directed downwardly from pallet side is gone out, is overlapped on the veneer of another inclined-plane upward；
4th step, starts top board hot pressing；
5th step, reaches setting time top board and rises solidification by cement completion automatically, open press, take out splice plate by specification point
Do not pile up；
6th step, is piled up, and descends sanction plate process.
Specifically, the specific process of the first step is：Veneer after being ground carries out specification screening and then matched somebody with somebody
Plate, then carries out block pattern row pattern up after plate face carries out gluing, gluing by grinding.
Specifically, the specific process of second step is：By glued order of all veneers that need to be integrated according to regulation
Piled up, the veneer order piled up is proofreaded after piling up.
Specifically, the specific process of the 3rd step is：Grinding surface veneer directed downwardly is inserted from the opposite side of pallet, with the
Face-up veneer progress is ground in one step staggered, and the gluing between plate face staggeredly.
Specifically, the specific process of the 4th step is：After integrating staggeredly, the veneer of gluing passes through the upper of hot press each other
Pressing plate carries out hot pressing, and veneer is carried out into justifying pressing by hot glue and hot pressing, and the time of hot pressing is carried out according to the width of plate face
Also can be different, when plate is wider than 1570 millimeters, hot pressing time is more than 65 seconds, when plate is wide is less than 1200 millimeters, hot pressing time
For 45 seconds, and the pressure value of whole hot press was more than 0.3MPa, and hot pressing temperature is between 180 to 199 DEG C.
Specifically, the specific process of the 5th step is：After reaching between compacting, hot press is opened, the sheet material after hot pressing is entered
Row is checked, if any the position for not being pressed gluing, its dry glue is purged, repeated the above steps, if after whole sheet material compacting
There is no defect to be piled up with installation specification.
Operation principle：Modified by original process, single sheet is subjected to gluing, then pass through hot pressing glue
