step two: the PLC 44 controls the first driving motor 35, the first driving motor 35 drives the blanking baffle 34 to open, the sectional material piece 37 in the storage bin 33 slides out of the storage bin 33 due to gravity after the blanking baffle 34 is opened, and the first driving motor 35 drives the blanking baffle 34 to close after the time that one sectional material piece 37 slides out, so that other sectional material pieces 37 in the storage bin 33 cannot slide out, and the sectional material piece 37 slides to the fixed-length outer shell 23 through the blanking sliding plate 36;

step three: the section piece 37 falls from the storage opening 232 at the top of the fixed-length outer shell 23 to the inside of the fixed-length outer shell 23 for fixation, the support block 243 inside the fixed-length outer shell 23 supports the section piece 37, then the PLC 44 controls the second hydraulic pump 46 to start, the second hydraulic pump 46 drives the second hydraulic telescopic column 47 to stretch downwards, and the second hydraulic telescopic column 47 drives the saw blade 48 to move downwards;

step four: PLC controller 44 controls second driving motor 49 and starts when saw bit 48 moves down, second driving motor 49 drives saw bit 48 and rotates, saw bit 48 gets into the inside cutting with section bar piece 37 of fixed length shell body 23 through going into fixed length cutting opening 233, PLC controller 44 controls first hydraulic pump 241 and starts after the cutting finishes, first hydraulic pump 241 drives first hydraulic telescoping post 242 and contracts, first hydraulic telescoping post 242 drives supporting shoe 243 and breaks away from fixed length shell body 23 is inside, make section bar piece 37 after the cutting is accomplished can be smoothly from fixed length shell body 23 inside drop to collect storehouse 25 inside, then personnel pulling handle 26 will collect storehouse 25 through universal pulley 27 and remove to the assigned position place can.

In summary, the following steps: the fixed-length cutting device for processing the section bar is characterized in that the position of the section bar 37 is fixed after the section bar 37 falls from the object placing opening 232 at the top of the fixed-length outer shell 23 to the inside of the fixed-length outer shell 23, the fixed-length cutting opening 233 fixes the cutting position of the saw blade 48, the saw blade 48 enters the fixed-length outer shell 23 through being clamped into the fixed-length cutting opening 233 to cut the section bar 37, the cutting length of the section bar 37 is consistent through the object placing opening 232 and the fixed-length cutting opening 233, the precision is high, the cut section plane is neat, defective products are avoided, the production efficiency of the device is improved, raw materials are saved, the device controls each part to operate through the PLC 44, the device automatically operates, manpower resources are saved, the device enables the section bar 37 not to collide together when falling, and the section bar 37 is prevented from being clamped in the fixed-length outer shell 23 when falling, can be smooth fall into inside collection storehouse 25, then personnel pulling handle 26 will collect storehouse 25 and remove to the assigned position through universal pulley 27 and place can for the collection of section bar piece 37 is very light, and it is convenient to transport.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
