Description
Technical field
The present invention relates to a kind of blanking device of truss web, especially suitable under English truss class gantry crane web member
Used during material.
Background technology
Use manual oxygen cutting during truss gantry crane girder web member blanking at present, worker's work is strong during manual oxygen cutting blanking
Spend big, operating efficiency is low, secondly because web member angle is difficult to control, manual oxygen cutting cuts glacing flatness and the visitor such as is difficult to ensure that in addition
Sight factor, cause the section that manual oxygen cutting is cut out to be often uneven, web member be placed between girder top-bottom chord occur it is very big
Gap, weld seam its quality between web member and chord member can not often ensure.Moreover also have and section bar is cut using sawing machine,
Such as round steel, cut off after gripping on the table using sawing machine, but existing girder web member is using rectangular tube, it is difficult to clamp
It can not be adjusted with fixed and rectangle tube angulation, so as to can not guarantee cutting stock precision.
The content of the invention
The task of the present invention is to propose a kind of automatic and accurate blanking, and holder is fixed, and ensures the weldering of web member and chord member weld seam
Connect a kind of blanking device of truss web of quality.
The task of the present invention is done in such a way that it includes rotation sawing machine, it is characterised in that：Rotation sawing machine is fixed on work
The top of platform, clamping device is installed on the work top, the clamping device is made up of fixed block and movable block, living
The bottom surface of motion block is installed in track, the fixed block be arranged on movable block to being fixed by bolts at face on work top,
The back side of the movable block is provided with an oil cylinder that movable block can be promoted to move, and fixed block fills on the clamping face of movable block
There is holder, there is a V-type opening on holder.One end of rotation sawing machine is connected with workbench, and switch board is positioned on workbench
The side in face, rotate and handwheel is housed in the fixing end of sawing machine.
The present invention has the following effects that：The technical program can make production efficiency improve more than 50 percent, ensure that down
Expect precision, girder web member and top-bottom chord is realized slitless connection, ensure that the welding quality of web member and chord member weld seam, can be real
The batch production of existing standard tonnage span truss class web member.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；Fig. 2 is the structural representation of fixed block；Fig. 3 is the structure in Fig. 2A-A directions
Schematic diagram.
Drawing explanation：1st, rotate sawing machine, 2, handwheel, 3, workbench, 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.
Embodiment
The technical program realizes the blanking to rectangular tube, institute using rotation sawing machine 1 using the holder on workbench
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 workbench of rotation sawing machine
Connection, the saw blade 5 equipped with cut-out rectangular tube on sawing machine is rotated, and rotation can be controlled by switch board 11 in X, Y plane, enter one
Step says that rotation sawing machine is fixed on the top of workbench, is provided with clamping device on 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 pair 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 adjust certain angle, scale is housed on the work top, switch board is positioned on work top
Side, rotate and handwheel 2 be housed in the fixing end of sawing machine, position of the handwheel control rotation sawing machine in horizontal plane.
During work, after accurate calculate, sawing machine is rotated away from working face, rectangular tube is placed on fixed block clamping face
In V-type opening, then sawing machine rotated to above work top, start oil cylinder pushing movable block and be moved to folder to fixed Block direction
After tight rectangular tube, shaking handwheel makes rotation sawing machine make in horizontal plane internal rotation certain angle, startup switch board button under sawing machine
Drop, rectangular tube is cut in two, and the fixed block can be changed according to angle of the rectangular tube on girder between lower edge, so as to
It ensure that cutting stock precision.
