Abstract
The utility model provides a combined type pneumatic blank pressing and stretching mould which comprises a female mould and a core column. A male mould and a cutting ring are fixedly installed at the lower end of the core column through inner hex head screws, a blanking cover is arranged outside the core column, a guide cover is arranged outside the blanking cover, the guide cover is fixed on the bottom of a cylinder barrel through a lower end cover, a piston is arranged between the upper portion of the blanking cover and the cylinder barrel, a half-moon ring and a gland are arranged at the upper end of the piston, a cylinder gland and a core column compressing block are arranged at the upper end of the cylinder barrel, the upper portion of the core column is connected with a stud bearing, an Igus cover is arranged between the guide cover and the blanking cover, an O-shaped sealing ring is arranged on the inner ring of the piston, a Glyd ring is arranged on the outer ring of the piston, and another O-shaped sealing ring is arranged between the upper cover of the cylinder and the cylinder barrel. The combined type pneumatic blank pressing and stretching mould solves the problems that mechanical fatigue is easy to occur and product quality is influenced after long-time use of a compression spring, the cylinder can provide constant pressure which is beneficial to the improvement of stretching quality, and the cylinder is further combined with the stretching mould to form a cylindric cylinder stretching mould.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of combined pneumatic flanging drawing die.
Background technology
Drawing die uses Compress Spring to guarantee the pressure-pad-force of binder cover usually, because spring structure is simple, cost is low, still be widely used within the specific limits, but the pressure-pad-force of spring is to be directly proportional with the deformation quantity of spring, and along with the increase of amount of spring compression, the pressure of spring multiple in direct ratio increases, it is a kind of relatively undesirable stretching situation in stretching work, after service time is long, produce easily mechanical fatigue, affect product quality.
Summary of the invention
The utility model provides a kind of combined pneumatic flanging drawing die, and the Compress Spring that has solved the drawing die in the background technology easily produces mechanical fatigue, affects the shortcoming of product quality.
The technical solution of the utility model is achieved in that a kind of combined pneumatic flanging drawing die, comprise die, stem stem, the stem stem lower end fixedly is equipped with punch and blank ring by soket head cap screw, the stem stem outside is provided with the binder cover, binder cover outside is provided with fairlead, fairlead is fixed on the bottom of cylinder barrel by bottom end cover, be provided with piston between binder cover top and the cylinder barrel, the piston upper end is provided with first quarter moon ring and gland, the cylinder barrel upper end is provided with cylinder gland and stem stem compact heap, and stem stem top links to each other with the double-screw bolt bearing;
Be provided with easy Gus's cover between fairlead and the binder cover;
The piston inner ring is provided with the O RunddichtringO, and the outer ring is provided with Glais ring;
Be provided with another O RunddichtringO between cylinder upper cover and the cylinder barrel.
The beneficial effects of the utility model are: after the utility model has solved Compress Spring length service time, produce easily mechanical fatigue, affect the difficult problem of product quality, and the pressure of spring changes greatly, and cylinder can provide quite constant pressure, be conducive to improve the stretching quality, and with the drawing die modular design, form the cylinder drawing die of a kind of cylinder (aluminium matter workpiece).

Part explanation: 1, punch, 2, the blank ring, 3, the binder cover, 4, stem stem, 5, fairlead, 6, bottom end cover, 7, piston, 8, the first quarter moon ring, 9, gland, 10, cylinder barrel, 11, cylinder upper cover, 12, the stem stem compact heap, 13, O RunddichtringO, 14, the O RunddichtringO, 15, easy Gus's cover, 16, die, 17, bolt bearing, 18, Glais ring.
The specific embodiment
1-2 is further described the utility model below in conjunction with accompanying drawing: 1, a kind of combined pneumatic flanging drawing die, comprise die 16, stem stem 4, stem stem 4 lower ends fixedly are equipped with punch 1 and blank ring 2 by soket head cap screw, stem stem 4 outsides are provided with binder cover 3, binder overlaps 3 outsides and is provided with fairlead 5, be provided with easy Gus between fairlead 5 and the binder cover 3 and overlap 15, can guarantee that binder overlaps 3 easy on and off and slides, fairlead 5 is fixed on the bottom of cylinder barrel 10 by bottom end cover 6, binder overlaps between 3 tops and the cylinder barrel 10 and is provided with piston 7, piston 7 inner rings are provided with O RunddichtringO 14, guarantee air seal, the outer ring is provided with Glais ring 18, effect is that dynamic seal (packing) adds guiding, piston 7 can drive binder cover 3 and move up and down under compressed-air actuated effect, piston 7 upper ends are provided with first quarter moon ring 8 and gland 9, first quarter moon ring 8,9 pairs of pistons 7 of gland play sealing, fixation, cylinder barrel 10 upper ends are provided with cylinder gland 11 and stem stem compact heap 12, be provided with O RunddichtringO 13 between cylinder upper cover 11 and the cylinder barrel 10, stem stem 4 tops link to each other with double-screw bolt bearing 17.
When stem stem 4 moves downward under bolt bearing 17 drives, whole cylinder barrel 10 all moves downward, after binder cover 3 touches die 16, stop motion, stem stem 4 continues to move downward, and punch 1 is finished stretching with die 16 actings in conjunction, and blank ring 2 is finished the side cut operation, when stem stem 4 moves upward under bolt bearing 17 drives, whole cylinder barrel 10 all moves upward, and binder cover 3 resets under compressed-air actuated effect, and stem stem 4 continues to move upward, punch 1 separates with die, finishes a stretching process.
