The purpose of this utility model is to adopt following technical scheme to realize: the hole punched device of described scaffold tube, it is characterized in that: adopt hole punched device to carry out punching on the steel plate before the scaffold tube moulding, described hole punched device, be installed in hydraulic press on, between the lower table face, it is by cope match-plate pattern, lower bolster, lifting column, the punch holder, punch, sideboard, cylinder, stripper, die, die holder and backing plate are formed, in cope match-plate pattern, four jiaos of installation lifting columns that distribute constitute square bearer between the lower bolster, the affixed punch holder in cope match-plate pattern bottom surface in square bearer, installing more than one group every group at the punch holder is two punch, and the centre-to-centre spacing of two punch must equate with the centre-to-centre spacing of adjacent two connecting holes of scaffold tube, corresponding with each punch position, the sideboard of band open-work on a side of punch holder is installed by air cylinder driven, towards a side of cylinder cushion block is housed at each open-work, below the punch holder, stripper is set, the die holder of dress die in connecting on the lower bolster below the stripper, install backing plate between die holder and the lower bolster, with corresponding, in being connected guide plate arrangement by the two ends of the lower bolster of the steel plate band import department of punching symmetry by the steel plate bandwidth of punching.
Described lifting column, be made up of fairlead, lead, it is corresponding with the position of each fairlead to connect fairlead at every angle of cope match-plate pattern, connects lead on lower bolster respectively, its each lead is inserted in respectively in the corresponding fairlead, and can do synchronous ascending, descending campaign in fairlead.It mainly is to make guiding to punch, die to use.
Described stripper, corresponding with each punch position, in its plate face, be provided with through hole.Be to be used for the steel plate band of staying on the punch owing to extruding force after the punch work is laid down, so that next stamping-out.
Described each punch is made up of convex die rod, punch case, returning spring, adorns convex die rod in punch case, suit returning spring on the convex die rod section in punch case.Described returning spring is when being in off position in punch returns to open-work on the sideboard, makes punch be returned to the operating position by the elastic force of spring itself.
Described guide plate arrangement is made up of guide roller, roll shaft and slide block.Slide block is installed on lower bolster, the roll shaft that has guide roller is installed on slide block.It is the device that processed steel plate is played guiding function, makes the steel plate band enter stamping-out position accurately by its guiding.
Described sideboard is the control device whether punch works, and it is by air cylinder driven, the piston rod by cylinder flexible, and punch work and idle switching are finished in the top that makes cushion block on the sideboard and open-work align punch in turn.
Described backing plate is that the immense pressure when preventing stamping-out produces the device that destroys to template, and it adopts the high material of hardness to make usually.Combine the above technical measures of being taked, realize the purpose of this utility model.
The punching operation traditional owing to the utility model and existing scaffold tube is different, the utility model is to carry out the punching operation before the scaffold tube moulding, just will need the steel plate band of punching to flow to the utility model by conveying equipment, at first the guide plate arrangement in the utility model enters between punch and the die, surveyed the accurate position of punching by optoelectronic device after, send signal to hydraulic press, hydraulic press is to pressing down, and the punching operation is finished in punch and die interlock; Then, hole punch steel plate band becomes scaffold tube by next procedure roll compacting.So, just solved the problem on deformation of scaffold tube when punching.Combine the above technical measures of being taked, realize the purpose of this utility model.
Compared with prior art, the utility model not only project organization is reasonable, because it is to adopt the pressure punching device on the steel plate before the scaffolding steel pipe moulding, this hole punched device not only project organization is reasonable, its punching concentricity height, versatility is good, and has the production efficiency height, handling safety is used characteristics such as very convenient.
