Specific embodiment
In the present embodiment, to optimize grid siding bending molding process in high muscle thickness rate, a kind of high muscle thickness rate Intranet is proposed
Lattice siding bend molding apparatus, the molding machine include lock pressing mold 4, and lock pressing mold 4 includes to cutter groove 41, formpiston 42, former 44
Sliding and flexible media 43, formpiston 42 are detachably mounted to in cutter groove 41, and former 44 is equipped with the first groove and the second groove, leans on
The diameter of first groove of nearly formpiston 42 is greater than the diameter of the second groove far from formpiston 42, the first groove and the combination of the second groove
Concave slot is formed, transition face, mistake are equipped between the lower horizontal plane of the first groove and the vertical plane of the second groove contacted therewith
It crosses between face and the lower horizontal plane of the first groove in obtuse angle, between transition face and the vertical plane of the second groove in obtuse angle.
In the present embodiment, V-groove is equipped with to cutter groove 41, the section of the formpiston 42 is sector, fan-shaped angle and V-groove
It is adapted, formpiston 42 is bolted on in cutter groove 41.
In the present embodiment, flexible media 43 is polyurethane rubber.
When installing lock pressing mold 4, formpiston 42 is connect by bolt with to cutter groove 41, then will be placed in the upper of bending machine to cutter groove 41
It is fixed by pressing plate 3 on die holder 2, then former 44 is placed on the workbench 6 on fuselage workbench 7 again, by adjusting plate
Behind 5 adjustment positions, former 44 is fixed on workbench 6, sliding block 1 is operated by digital control system when lock is pressed and is moved down, formpiston is made
42 and former 44 come into full contact with.
In the present embodiment, the method for grid siding brake forming in high muscle thickness rate, comprising steps of
S1. grid siding in high muscle thickness rate is pressed using grid siding bend molding apparatus lock in above-mentioned high muscle thickness rate, passed through
