Description

The whole process guiding hot punching blank punching device of a kind of pair of guide pillar structure
Technical field
The invention belongs to the pressure processing technology field, relate to the hot punching blank punching device of a kind of pair of guide pillar structure.
Background technology
In many industrial processes field, need produce tubular metal parts, for example shell body, tool joint, oxygen cylinder etc. with certain intensity.When making these parts, can utilize red stamping technology to carry out blank processing usually, the blank metal continuity that processes is good, and can directly bar be processed into required form, and the specification condition restriction to bar is little simultaneously, can improve the performance of material.
In addition, to add the equipment that adopts man-hour all be to utilize the precision of equipment itself to guarantee the precision of red punching press blank adopting red punching press to carry out blank, and the sexual needs that liquidate of mould are manually constantly adjusted in process, and deviation appears in machining accuracy easily.
Summary of the invention
The objective of the invention is to adopt red punching press to carry out the precision problem that blank adds man-hour, propose the whole process guiding hot punching blank punching device of a kind of pair of guide pillar structure for solving.
The technical solution adopted in the present invention is as follows:
The whole process guiding hot punching blank punching device of a kind of pair of guide pillar structure comprises upper bolster, die shoe, shedding mechanism, material jacking mechanism, cooling body, punch-head assembly and die assembly.
Upper bolster links to each other with outside press moved cross beam, and cooling body, punch-head assembly all are fixed in the upper bolster.Shedding mechanism is fixed on the die assembly, and die assembly is fixed in the cavity of die shoe.Material jacking mechanism passes to the press of outside from the cavity of die shoe and the cavity of die assembly.
Have the through hole of two symmetries at the work top of die shoe, simultaneously, on the template of the upper bolster of hot punching blank punching device, have the through hole of two symmetries.
Be inserted in a sleeve in each through hole, sleeve adopts and is bolted on the work top of die shoe.
Adopt interference fit to be fixed together at an end of a guide pillar with upper bolster template through hole.The other end of guide pillar passes sleeve, and can slide in sleeve.
The course of work of this device is as follows:
When carrying out red punching operation, at first, the press moved cross beam is mentioned upper bolster, drives punch-head assembly and upwards mentions the die cavity that leaves die assembly.Simultaneously, driving guide pillar moves upward.
When the press moved cross beam reaches upper limit, in the die cavity of die assembly, put into blank.Afterwards, punch-head assembly is descending under the drive of press moved cross beam, and blank is carried out punching.At this moment, guide pillar will not advance in the sleeve towards contacting blank under drift.In punch process, guide pillar passes sleeve, thereby has avoided the deviation of blurting out.
After the press moved cross beam arrived lower limit, moved cross beam drove the punch-head assembly backhaul, and shedding mechanism stays blank in the die cavity of die assembly.Afterwards, the shedding mechanism return, moved cross beam drives punch-head assembly and gets back to upper limit, and the liftout attachment of press promotes the die cavity that material jacking mechanism ejects blank die assembly.At last, material jacking mechanism return.A punching press is finished.Cooling body cools off punch-head assembly in whole process.
Beneficial effect
Apparatus of the present invention, contrast existing equipment and process have the following advantages:
The existing equipment low precision, mould unbalance stress during mold work causes the wall thickness that drift is crooked, the generation of punching press blank is bigger poor.For the wall thickness that reduces red punching press blank poor, reduce the allowance of blank, reduce the norm of material consumption and follow-up machine and add cost, it is poor to remedy equipment precision by the omnidistance guiding of the outer guiding post mould that adopts high strength, high accuracy, high rigidity, increased drift and perforating die to neutrality, reduced human factor, uneven stressed when having improved frock work, increase the frock life-span, reduced the wall thickness deviation of red punching press blank, thereby saved raw material.
Description of drawings
Fig. 1 is the structure composition frame chart of the specific embodiment of the invention.
Fig. 2 is the schematic diagram that concerns of die shoe 2 in the specific embodiment of the invention, first through hole 8, sleeve 10;
Fig. 3 be in the specific embodiment of the invention upper bolster 1 and second through hole 9 concern schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further details.
The whole process guiding hot punching blank punching device of a kind of pair of guide pillar structure as shown in Figure 1, comprises upper bolster 1, die shoe 2, shedding mechanism 3, material jacking mechanism 4, cooling body 5, punch-head assembly 6 and die assembly 7.
Upper bolster 1 links to each other with outside press moved cross beam, and cooling body 5, punch-head assembly 6 all are fixed in the upper bolster 1.Shedding mechanism 3 is fixed on the die assembly 7, and die assembly 7 is fixed in the cavity of die shoe 2.Material jacking mechanism 4 passes to the press of outside from the cavity of die shoe 2 and the cavity of die assembly 7.
Have first through hole 8 of two symmetries at the work top of die shoe 2, be inserted in a sleeve 10 in each first through hole 8, sleeve 10 adopts and is bolted on the work top of die shoe 2, as shown in Figure 2.Simultaneously, on the template of the upper bolster 1 of hot punching blank punching device, have second through hole 9 of two symmetries, as shown in Figure 3.
Adopt interference fit to be fixed together at an end of a guide pillar 11, can adopt the lifting screw further fixing with upper bolster 1 template second through hole 9.The other end of guide pillar 11 passes sleeve 10, and can slide in sleeve 10.
The course of work of this device is as follows:
When carrying out red punching operation, at first, the press moved cross beam is mentioned upper bolster 1, drives punch-head assembly 6 and upwards mentions the die cavity that leaves die assembly 7.Simultaneously, driving guide pillar 11 moves upward.
When the press moved cross beam reaches upper limit, in the die cavity of die assembly 7, put into blank.Afterwards, punch-head assembly 6 is descending under the drive of press moved cross beam, and blank is carried out punching.At this moment, guide pillar 11 will not advance in the sleeve 10 towards contacting blank under drift.In punch process, guide pillar 11 passes sleeve 10, thereby has avoided the deviation of blurting out.
After the press moved cross beam arrived lower limit, moved cross beam drove punch-head assembly 6 backhauls, and shedding mechanism 3 stays blank in the die cavity of die assembly 7.Afterwards, shedding mechanism 3 returns, moved cross beam drives punch-head assembly 6 and gets back to upper limit, and the liftout attachment of press promotes the die cavity that material jacking mechanism 4 ejects blank die assembly 7.At last, material jacking mechanism 4 returns.A punching press is finished.Cooling body 5 cools off punch-head assembly 6 in whole process.
