(otherwise will cause previous aluminium bar or the clipped generation aluminium bar thin slice of latter aluminium bar) directly can clamp aluminium bar head by detaining stick block
Aluminium bar is pulled out forward shelf position (aluminium bar can not be ejected by not shearing Shi Ding stick mechanism) by portion, so that the transverse-moving mechanism that makes to take over the baton is suitable
The removing aluminium bar of benefit, to improve production efficiency, reduces the loss of aluminium bar；
Jia Bang mechanism is mainly used for stub clamping operation, and concrete condition is to exist when previous long aluminium bar is trimmed to residue length
When between one times of cut lengths and 2 times of cut lengths (waste that there will certainly be one section of aluminium bar to cut lengths is sheared at this time),
The residue length aluminium bar can be cut into two sections of roughly equal front and back stub (two sections are respectively less than cut lengths) by hot shears,
Back segment stub is picked up by Jia Bang mechanism first, long aluminium bar latter at this time ejects leading portion stub, will be latter by hot shears
Long aluminium bar shears next section of stub, this section of stub can be by leading portion stub polishing to cut lengths, and by taking over the baton, translation mechanism will
The leading portion stub of polishing to cut lengths, which removes, to be sent into extruder；Latter long aluminium bar is retracted heating furnace by rod-back machine structure at this time
Interior, Jia Bang mechanism puts down back segment stub, and latter long aluminium bar ejects back segment stub, is cut latter long aluminium bar again by hot shears
One section of stub is cut, this section of stub can be by back segment stub polishing to cut lengths, by translation mechanism of taking over the baton by polishing to calmly
The back segment stub of ruler length, which removes, to be sent into extruder, and this mode can greatly reduce the loss of aluminium bar, effectively increase
Stock utilization.
In addition to the implementation, all to use equivalent transformation or equivalent replacement the invention also includes there is an other embodiments
The technical solution that mode is formed should all be fallen within the scope of the hereto appended claims.
