The square tube die mould drilling mold of a kind of die mould and punching one-step moulding, applied to machining equipment field.The square tube pipe fitting of mold processing can be directly bolted with other components, other auxiliary parts and process is not required.It includes upper die and lower die, and the upper mold is made of cope plate, upper die plate, upper mould fixed plate, guide sleeve, spring, punch retainer and punch-pin, and the lower die is made of lower mold fixed plate, lead, cavity plate, jacking block.Compared with prior art, the invention has the advantages that：1st, the attachmentes such as sealing plate, gusset and bottom plate are eliminated, quantities is reduced, has saved cost.2nd, processing is simple and fast, is easily installed, is readily transported, shortens the duration.3rd, reduce the welding job amount of steel structure node, reduce manually, reduce labour cost.
Description
Technical field
The invention belongs to machining equipment fields, and in particular to the square tube die mould system of a kind of die mould and punching one-step moulding
Punch die.
Background technology
Existing steel structure bolt connecting node gusset is numerous, must weld.Being welded to connect can have the disadvantage that：
1. in the heat affected area near weld seam, the metallographic structure of steel changes, and local material is caused to become fragile；
2. welding residual stress and residual deformation make the reduction of compression member bearing capacity；
3. welding structure is very sensitive to crackle, localized cracks are easy for expanding to entirety, brittle fracture under low temperature problem is more once occurring
It is prominent.
4. welding, gusset is numerous, and welding capacity is big, and processing is relative complex, and processing is long in time limit.
5. cost is higher, during factory process, part square tube, sealing plate, gusset and bottom plate is welded into an entirety, then arrived
Assembling.Rod piece space hold with sealing plate, gusset and bottom plate is larger, transport difficult, and transportation cost is larger.
The content of the invention
The purpose of the present invention is intended to provide a kind of composite die of structurally simple, economical practicality.Side after this mould molding
Pipe flattens, punching one-step moulding, is bolted convenient for rod piece is subsequent.It can be on the basis for reducing quantities, reducing cost
On, it improves construction efficiency, realize engineering equipment, EM equipment module, modularization standardization.Square tube rod piece after the processing of this mold is not
Need additional sealing plate, gusset, bottom plate that can be bolted with steel column.Steel have been saved, have eliminated the expense of human weld
With shortening the duration, greatly reduce cost.
A kind of square tube die mould drilling mold of die mould and punching one-step moulding, for processing square tube end, including upper mold, under
Mould, it is characterised in that：The upper mold includes cope plate, guide sleeve, punch-pin, and two guide sleeves, convex are fixedly connected with below cope plate
Mould, piercing punch, the lower die are made of lower mold fixed plate, lead, cavity plate, jacking block, and lower mold fixed plate the upper surface of is fixed to be connected
It connects there are two lead, cavity plate and jacking block, lead is mating with guide sleeve, and cavity plate and jacking block are located between two leads, top
Block is located between two cavity plates.
Compared with prior art, the invention has the advantages that：
1st, the attachmentes such as sealing plate, gusset and bottom plate are eliminated, quantities is reduced, has saved cost.
2nd, processing is simple and fast, is easily installed, is readily transported, shortens the duration.
3rd, reduce the welding job amount of steel structure node, reduce manually, reduce labour cost.

Specific embodiment
A kind of square tube die mould drilling mold of die mould and punching one-step moulding, for processing square tube end, it include upper mold,
Lower die.
Shown in Fig. 1, Fig. 2, Fig. 3, the upper mold is by cope plate 1, upper die plate 2, upper mould fixed plate 3, guide sleeve 4, spring
5th, punch retainer 6 and punch-pin 7 form, and two guide sleeves and one piece of upper die plate, upper die plate are fixedly connected with below cope plate
Between two guide sleeves, upper mould fixed plate is arranged below in upper die plate, and upper mould fixed plate 3 is fixedly connected with piercing punch
11, punch retainer 6 is fixedly connected with die mould punch-pin 7.Spring 5, spring are provided between upper mould fixed plate and punch retainer
There is two level lead 13 in inside.
Shown in Fig. 4, Fig. 5, Fig. 6, the lower die is made of lower mold fixed plate 10, lead 8, cavity plate 9, jacking block 12, lower die
Fixed plate the upper surface of is fixedly connected there are two lead, cavity plate and jacking block, and lead is mating with guide sleeve, and cavity plate and jacking block are located at
Between two leads, jacking block is located between two cavity plates.
The present invention is compound die, and flattening, punching two procedures are completed in a stroke.Square tube after processing can be direct
It is bolted with component, auxiliary gusset need not be further added by.
Operation principle of the present invention：Upper mold is linked by die shank and slider of punch.Lower die is fixed on punching machine using pressing plate
On workbench.Upper mold is oriented to lower die by lead.
During work, square tube is sent into against backgauge and positions, and when upper mold declines with slider of punch, punch-pin 7 is first flattened and is arranged on
The square tube workpiece of die top completes flattening process.
Then the punching mold compression spring in upper mold, which continues to decline, completes punching operation.At this moment square tube workpiece be stuck in punch-pin with
Between jacking block, when upper mold is gone up, square tube workpiece borrows the elastic force of spring to be ejected from cavity plate hole by jacking block by top plate, then takes away
Square tube workpiece, so far completes whole work process.
