Description
Technical field
A kind of punching die is the utility model is related to, more particularly to it is a kind of in I-steel, the I-shaped of H profile steel punching, H profile steel
Double punching die.
Background technology
Annex manufacture uses the load bearing cross beam of I-steel, H profile steel as tower inner platform, present production in wind-power tower
Manufacturing process is using the landing slab mounting hole on drilling machine drilling or plasma cut machine cut crossbeam.Drilling efficiency is low, pitch-row
Low precision and round hole can only be bored；The appearance shaping of plasma cut machine cut hole is poor, and dimensional accuracy does not reach requirement, and cost is excessive.
Utility model content
The purpose of this utility model is to disclose the low I-shaped of a kind of high punching efficiency, pitch-row accurate, appearance looks elegant, cost, H
The double punching die of shaped steel.
To solve the above-mentioned problems, using following technical scheme：
The double punching die of I-shaped, H profile steel, including mold and lower mould, between upper and lower mould seat board by guide post and
Guide column sleeve is oriented to, and mold includes mold seat board, mold die shank, mold fixture, material returned buffer stopper and double upper punch,
Mold fixture is connected with mold seat board, and lower mould includes lower clamping cap and lower punch, and lower punch fixes lower clamping cap
On；The lower punch is that the cavity plate that upper surface is the bilateral gear structure of double inclined plane, its inclined-plane and the I-steel processed or H profile steel are cut
The gradient and flange width in face are adapted, and the cavity that the lower end of two opposite lower clamping caps is surrounded is taper, its inclined-plane
Gradient is adapted with the I-steel or the gradient in H profile steel section processed.
Above-mentioned I-shaped, the double punching die of H profile steel, the mold die shank are corresponding with the size in punching machine storehouse hole.
Above-mentioned I-shaped, the double punching die of H profile steel, the guide column sleeve and guide post use ball Guide column component.
Above-mentioned I-shaped, the double punching die of H profile steel, the upper punch rush for circular apertures punch or other class type holes
Head, using being heat-treated after the turning of 45# steel or linear cutter, hardness reaches HRC58-60.
Above-mentioned I-shaped, the double punching die of H profile steel, the lower punch use 40Gr alloy steel heat treatments, and hardness reaches
It is molded after to HRC58-60 according to upper punch size and lower clamping cap fit dimension wire cutting.
Above-mentioned I-shaped, the double punching die of H profile steel, the material returned buffer stopper use polyurethane elastomeric materials, it is grown
Short size is corresponding with the length size of upper punch.
Using the double punching die of the structure, overcome I-steel, H profile steel section is gradient can not be processed in punching machine
The difficult point that is clamped in journey, using double inclined plane, bilateral gear position lower punch mould, and double punch punchings, can rush round hole but also rush it
Its class type hole, using special positioning and discharging device, makes work efficiency improve 20 times, and ensure that machining accuracy.
Brief description of the drawings
Fig. 1 is the structure diagram with upper punch of the utility model.
Fig. 2 is the structure diagram with material returned buffer stopper of the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, it is oriented between mold seat board 2, lower mould seat board 10 by guide post 4 and guide column sleeve 3, lower punch
8 are fixed on lower clamping cap 9 with high-strength bolt；Mold die shank 1 is fixed on mold seat board 2 with high-strength bolt
Side, mold fixture 5 are fixed below mold seat board 2 with high-strength bolt, and material returned buffer stopper 7 and double upper punch 6 are fixed
On mold fixture 5, lower punch 8 is the cavity plate that upper surface is the bilateral gear structure of double inclined plane, its inclined-plane and the I-shaped processed
The gradient and flange width in steel or H profile steel section are adapted, and the cavity that the lower end of two opposite lower clamping caps 9 is surrounded is cone
Shape, the gradient on its inclined-plane are adapted with the I-steel or the gradient in H profile steel section processed, the position of relief hole 11 and upper punch 6
Put corresponding, which overcomes I-steel, the gradient difficult point that can not be clamped in punching machine process in H profile steel section, adopts
With double inclined plane, bilateral gear positioning lower punch, double punch punchings, can rush round hole but also rush other class type holes, using guide sleeve with
Guide post realizes the positioning of punch and lower punch, and the center of punching shaped steel is ensured using double inclined plane, bilateral gear positioning lower punch,
Longitudinally guiding and the fixation of shaped steel are carried out using lower clamping cap, is completed with reference to positioning device of hole gap in the reciprocating motion of punching machine
Rush circular hole or other class type holes.
