At present, the inner tube of steel support post is to make with pipe, and external diameter is generally 48mm, and internal diameter is 40mm, and length is more than 1500mm-2500mm, is arranging the through hole of diameter 15mm-20mm above inner tube, and quantity is minimum more than 10.Traditional machining methods are the dimensional requirements according to hole, choose the drill bit of corresponding size and process with drilling machine, are subject to the restrictive condition of machining, and speed can not improve, and the efficiency of processing is very low, and can accurately the machining hole position; Because of the wearing and tearing of drill bit, do not guarantee the dimensional accuracy in hole; Iron filings, along with drill bit screws out, easily enter drill bit by operator's hand scroll, cause industrial accident; The hole of drill bit processing also is with jagged, needs special messenger's cleaning of polishing, and has increased operation, and potential safety hazard is very large.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of hole punched device that can improve punching efficiency.

For solving the problems of the technologies described above, the utility model comprises base plate, the base plate right-hand member is fixed with the plug fixture, the plug fixture is provided with the plug apart from the plate upper surface certain distance, plug is provided with and steel pipe to be processed position, the through hole that size is corresponding, base plate under described plug is provided with the steel pipe stopper slot adapted with outer diameter of steel pipes, described plug top is provided with die shank, be fixed with the red needle fixed form on die shank, red needle fixed form below is provided with a plurality of red needles corresponding with through hole, the corresponding through hole of base plate is provided with lower through-hole, the lower through-hole below is provided with material-dropping hole, be respectively equipped with cutting edge in described through hole and lower through-hole, on described base plate, be equipped with for the lead to red needle fixed form guiding.

Described plug right-hand member is provided with a plurality of locating holes, and the spacing of the spacing between the adjacent positioned hole and the punching of steel pipe to be processed adapts.

Described plug fixture comprises the bottom plate that is fixed on the base plate right-hand member, has been bolted upper mounted plate on bottom plate, forms the plug plug-in opening between upper mounted plate and bottom plate, and the plug right part is inserted in the plug plug-in opening fixing.

Described lead is two, and the red needle fixed form is run through in its ，Qi upper end, both sides that is symmetricly set on plug.

After adopting said structure, hole punched device is arranged on drilling machine, by red needle, replaces drill bit, guarantee the precision of Kong Yukong position, reduce costs, save the energy.Aspect technical operation, operate this kind of drilling machine and compare the with low content of technology of common driller, the worker training is easy.Because the utility model is special-purpose punching die, people's hand, away from drift, can not hindered hand, with the iron filings of drilling machine, easily rolls up palmistry relatively, and the utility model is safer, thoroughly eliminates safe hidden trouble, and more easily implements.

The accompanying drawing explanation

Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the cross-sectional schematic of Fig. 1 along the A-A line.

The specific embodiment

As depicted in figs. 1 and 2, hole punched device comprises base plate 1, base plate 1 right-hand member is fixed with the plug fixture, the plug fixture comprises the bottom plate 3 that is fixed on base plate 1 right-hand member, the upper surface of bottom plate 3 is provided with the arc lower hole, on bottom plate 3, by bolt 5, is fixed with upper mounted plate 4, and the corresponding arc lower of the lower surface of upper mounted plate 4 hole is provided with arcuate socket, arc lower hole and upper arcuate socket form the plug plug-in opening, and plug 2 right parts are inserted in the plug plug-in opening fixing.Plug 2 left ends are provided with and steel pipe to be processed position, the through hole 17 that size is corresponding, plug 2 right-hand members are provided with a plurality of locating holes 11, the spacing of the spacing between adjacent positioned hole 11 and the punching of steel pipe to be processed adapts, base plate 1 under plug 2 is provided with the steel pipe stopper slot 15 adapted with outer diameter of steel pipes, in the time of can preventing punching by steel pipe stopper slot 15 is set, steel pipe 14 moves, plug 2 tops are provided with die shank 6, be fixed with red needle fixed form 7 on die shank 6, red needle fixed form 7 belows are provided with four red needles corresponding with through hole 8, the size of red needle 8 and the spacing of adjacent two red needles are corresponding with the punching of steel pipe to be processed, the corresponding through hole of base plate 1 is provided with lower through-hole 9, lower through-hole 9 belows are provided with material-dropping hole 10, wherein through hole 17, lower through-hole 9 and material-dropping hole 10 coaxially arrange, be respectively equipped with cutting edge 16 in through hole 17 and lower through-hole 9, on base plate 1, be equipped with for the lead 13 to red needle fixed form 7 guiding, lead 13 is two, it is symmetricly set on the both sides of plug, red needle fixed form 7 is run through in its upper end.
