Description
Technical field
What the utility model full-automatic dry powder press core bar cylinder related to is stripper apparatus behind a kind of full-automatic dry powder press.
Background technology
Usually, full-automatic dry powder press core bar part directly is fixed on the second line of a couplet fishplate bar of template, when the demoulding, second line of a couplet fishplate bar and concave template action downwards simultaneously carry out the demoulding, for the bigger part of knockout press, easy pressed compact with stamping draws bad, causes pressed compact to scrap.
Summary of the invention
The purpose of this utility model is to provide a kind of full-automatic dry powder press core bar cylinder at above-mentioned weak point, adopt the core bar cylinder to carry out the back demoulding, can reduce knockout press, can guarantee that pressed compact good after the punch forming is intact, be specially adapted to valve guide bushing forming parts and thin wall type blank material charging forming.
Full-automatic dry powder press core bar cylinder takes following scheme to realize: full-automatic dry powder press core bar air cylinder structure comprises second line of a couplet fishplate bar, backing plate, cylinder body, sealing ring, gland, pad, core bar, piston, piston rod, adapter sleeve, adjusting nut, core bar connecting rod.
Second line of a couplet fishplate bar is contained in the following guide pillar lower end of dry powder press, cylinder body is contained on the second line of a couplet fishplate bar, between cylinder base and the second line of a couplet fishplate bar backing plate is housed, and piston, piston rod are housed in the cylinder body, piston rod top is connected with the core bar connecting rod by adapter sleeve, and core bar is fixed on core bar connecting rod top.The sealing ring gland is contained in cylinder body top, on the sealing ring gland sealing ring is housed.Pad is contained in the cylinder body upper end, and pad plays wear-resisting effect through after the Quenching Treatment.Adjusting nut is contained on the core bar connecting rod by screw thread, is used to regulate the core bar height, and core bar is flushed with die.
The core bar gland can be housed to reach the fixedly purpose of core bar between adjusting nut and cylinder body, make core bar become fixed core bar.
Cylinder body top is provided with the epicoele air inlet, and inferior part of the cylinder block is equipped with the cavity of resorption air inlet.
Full-automatic dry powder press core bar cylinder is realized three kinds of functions:
1, when full automatic press demoulding end, core bar is below being positioned under the effect of hydraulic pressure or air pressure, and die at first moves downward to demoulding position after the blank compression moulding, and core bar is because the effect of frictional force is positioned at the top; After die arrived demoulding position, core bar promoted piston rod under hydraulic pressure or the effect of air pressure medium and moves downward in cylinder body, break away from type blank.Die, core bar break away from moulded blank respectively, can reduce knockout press.
2, when full automatic press demoulding end, core bar is below being positioned under the effect of hydraulic pressure or air pressure; Die filling, core bar continue to be positioned at the below; Die sand off, core bar promote piston rod and move upward and carry out powder and fill under hydraulic pressure or the effect of air pressure medium in cylinder body; Get rid of many coreds bar part powder; Compacting finishes, and at first die is deviate from, and core bar promotes piston rod under hydraulic pressure or the effect of air pressure medium and moves downward in cylinder body then, deviates from moulded blank; Unsteady core bar is mainly used in the valve guide bushing forming parts.
3, when full automatic press demoulding wire harness, core bar is below being positioned under the effect of hydraulic pressure or air pressure; Die filling, core bar continue to be positioned at the below; Die filling, core bar promote piston rod and move upward under hydraulic pressure or the effect of air pressure medium in cylinder body, get rid of the powders of the many dresses of core bar part; Compacting finishes, and die, core bar move downward the demoulding simultaneously.The method is mainly used in the charging of thin wall type blank.
Reasonable in design, the compact conformation of full-automatic dry powder press core bar cylinder, owing to adopt the core bar cylinder to carry out the back demoulding, can reduce knockout press, get rid of many coreds bar part powder, can guarantee that pressed compact good after the punch forming is intact, be specially adapted to valve guide bushing forming parts and thin wall type blank material charging forming.
