Description
Technical field
This utility model is related to a kind of blanking device of truss web, is particularly well-suited to English truss class gantry crane abdomen
Use during bar blanking.
Background technology
Manual oxygen cutting is adopted during truss gantry crane girder web member blanking at present, workman's work is strong during manual oxygen cutting blanking
Big, inefficiency is spent, secondly because web member angle is difficult to control, and manual oxygen cutting cuts glacing flatness and is difficult to ensure that and waits objective in addition
Sight factor, causes the section that manual oxygen cutting cuts out to be often uneven, web member be placed between girder top-bottom chord occur it is very big
Gap, the weld seam between web member and chord member its quality cannot often ensure.Moreover also have and section bar is cut using sawing machine,
Such as round steel, cut off using sawing machine after gripping on the table, but existing girder web member uses rectangular tube, it is difficult to clamped
Cannot adjust with fixed and rectangle tube angulation, so as to can not guarantee cutting stock precision.
The content of the invention
Task of the present utility model is to propose a kind of automatically accurate blanking, and holder is fixed, it is ensured that web member and chord member weld seam
Welding quality a kind of truss web blanking device.
Task of the present utility model is done in such a way that it includes rotating sawing machine, it is characterised in that：Rotation sawing machine is fixed on
The top of work platformses, is provided with clamping device on the work top, the clamping device is by fixed block and movable block structure
Into, the bottom surface of movable block is installed in track, the fixed block be arranged on movable block to being fixed by bolts to workbench at face
On face, the back side of the movable block is provided with an oil cylinder that movable block can be promoted to move, clamping of the fixed block in the face of movable block
Holder is housed on face, on holder, has a V-type opening.One end of rotation sawing machine is connected with work platformses, and switch board is positioned on
The side of work top, rotates.
This utility model has the effect that：The technical program can make production efficiency improve more than 50 percent, it is ensured that
Cutting stock precision, makes girder web member realize slitless connection with top-bottom chord, it is ensured that the welding quality of web member and chord member weld seam,
The batch production of standard tonnage span truss class web member can be realized.
Description of the drawings
Fig. 1 is structural representation of the present utility model；Fig. 2 is the structural representation of fixed block；Fig. 3 is Fig. 2A-A directions
Structural representation.
Drawing explanation：1st, rotate sawing machine, 2, handwheel, 3, work platformses, 4, oil cylinder 5, saw blade, 6, track, 7, living
Motion block, 8, rectangular tube, 9, holder, 10, fixed block, 11, switch board, 12, V-type opening.
Specific embodiment
The technical program realizes the blanking to rectangular tube, institute using rotation sawing machine 1 using the holder on work platformses
It is that prior art is not described in detail to state rotation sawing machine.Specific embodiment is as shown in figure 1, one end and the work platformses of rotation sawing machine
Connection, rotates the saw blade 5 equipped with cut-out rectangular tube on sawing machine, it is possible to controls rotation by switch board 11 in X, Y plane, enters one
Step says that rotating the top that sawing machine is fixed on work platformses, clamping device being provided with the work top, the clamping device is
It is made up of fixed block 10 and movable block 7, the bottom surface of movable block is installed in track 6, and the fixed block is arranged on the right of movable block
It is fixed by bolts at face on work top, the back side of the movable block is provided with an oil cylinder 4 that movable block can be promoted to move,
Fixed block is equipped with holder 9 on the clamping face of movable block, has a V-type opening 12 on holder, this V-type opening entirety angle
90 ° of degree guarantee is constant, but the X angles in V-type opening can be adjusted between 30 ° ~ 60 °, it is therefore an objective to can firmly clamp square
The tube wall of shape pipe simultaneously can make rectangular tube adjustment certain angle, and scale is housed on the work top, and switch board is positioned on work top
Side, rotate, handwheel control rotation position of the sawing machine in horizontal plane.
During work, Jing after accurate calculating, sawing machine is rotated away from into work surface, rectangular tube is placed on into fixed block clamping face
In V-type opening, then sawing machine is rotated to above work top, start oil cylinder pushing movable block and folder is moved to fixed Block direction
After tight rectangular tube, shake handwheel makes rotation sawing machine rotate to an angle in horizontal plane, and starting switch board button makes under sawing machine
Drop, rectangular tube is cut in two, and the angle that the fixed block can be according to rectangular tube between lower edge on girder is changed, so as to
Ensure that cutting stock precision.
