Abstract
The utility model discloses a novel tensile hydraulic press adopting an oil cylinder and two sets of double-toggle mechanism as the crimping mechanism of the hydraulic press. The toggle mechanisms have the action of enlarging force to reduce the dimensions of the oil cylinder; only one small oil cylinder is provided; because of the self-locking function of the toggle mechanisms, pressure can be maintained even when the power of the oil cylinder is disassembled; therefore, oil does not need to be supplied for maintaining pressure, the oil circuit system is simple, the blank holder force is large, the speed is fast. Simultaneously the crimping mechanism and an adjusting mechanism for adjusting the size of the blank holder force are also arranged; a single toggle mechanism, a double-toggle mechanism and a multiple-toggle mechanism can be adopted according to different requirements.
Description
Hydraulic drawing press belongs to forging machine tool.
The hydraulic drawing press of using has two kinds of forms at present: 1, the hydraulic drawing press of band flanging oil cylinder, and blank body directly adopts oil cylinder, reach enough pressure-pad-forces, cylinder sizes is bigger, generally on four angles, adopt four, the oil cylinder number of elements is more, big with oil mass, need continuous repairing, keep-up pressure the oil piping system complexity, speed is slower, and cycle period is longer; 2, the hydraulic drawing press of band hydraulic die cushion, blank body adopts hydraulic die cushion, plays the flanging effect, the hydraulic die cushion complex structure, size is bigger, and oil piping system complexity, speed are also slower, and cycle period is longer.
The purpose of this utility model is to design has only a small size oil cylinder, does not need the repairing pressurize, and oil piping system is simple, big pressure-pad-force is arranged, and speed adopts the hydraulic drawing press of duplex rod-type blank body faster.
The design that achieves the above object is to adopt an oil cylinder and two to overlap the blank body of dual-elbow-bar mechanisms as hydraulic drawing press, again by the hydraulic oil cylinder driving elbow-bar mechanism, reach the flanging effect, elbow-bar mechanism has the effect of amplification power, and cylinder sizes is dwindled, because of elbow-bar mechanism has self-locking action, also can pressurize even shed oil pump power, reach energy efficient, quick action, cycle period is short, the purpose that efficient is high.
The advantage that adopts this dual-elbow-bar mechanism is the effect that elbow-bar mechanism has amplification, and cylinder sizes is dwindled a lot, and it is bigger to produce pressure-pad-force, and pressure-pad-force is stable, is difficult for changing fluctuation, because of elbow-bar mechanism has self-locking action, also can keep-up pressure workpiece pressing even shed oil pump power.Another advantage of the utility model is the size that blank body can be regulated four jiaos of pressure-pad-forces.
Fig. 1 is the front view of the utility model hydraulic drawing press;
Fig. 2 is a side view.
Be further described in conjunction with the accompanying drawings:
Hydraulic drawing press is by entablature 5, flanging entablature 8, flanging sill 12, sill 15, four root posts 6, oil cylinder 1,2, four adjusting screw mandrels of piston 4 and regulate nut 3 and blank body is formed.Blank body is made up of an oil cylinder 14 and two cover dual-elbow-bar mechanisms.Described elbow-bar mechanism is by oil cylinder 14, piston 13, and piston rod 17, distance rod 19, toggle link 18, support 16,21, strut 20 is formed.Piston 13 is arranged in the oil cylinder 14, oil cylinder 14 is installed in sill 15 centers, piston rod 17 1 ends are connected with piston 13, the other end is a T shape plate, four jiaos of T shape plate respectively with distance rod 19,19 ', 19 ＂, the a of 19 , a ', a ＂, a is point articulated, distance rod 19,19 ', 19 ＂, the other end of 19 and toggle link 18,18 ', 18 ＂, the b of 18 , b ', b ＂, b is point articulated, toggle link 18,18 ', 18 ＂, the lower end of 18 and support 16,16 ', 16 ＂, 16 are hinged, support 16,16 ', 16 ＂, 16 are fixedlyed connected with sill 15, toggle link 18,18 ', 18 ＂, the c of 18 , c ', c ＂, c point and strut 20,20 ', 20 ＂, 20 are hinged, strut 20,20 ', 20 ＂, the other end of 20 and support 21,21 ', 21 ＂, 21 are hinged, support 21,21 ', 21 ＂, 21 are fixedlyed connected with flanging sill 12.
The operation principle of blank body: the cavity of resorption oil-feed of oil cylinder 14, oil pressure moves up piston 13, and piston rod 17 moves up thereupon, impel distance rod 19,19 ', 19 ＂, 19 outwards move, make toggle link 18,18 ', 18 ＂, 18 rotate, by strut 20,20 ', move on 20 ＂, 20 , flanging sill 12 is moved up, impelling up and down, mould 9,11 compresses stretched part 10, oil cylinder 1 epicoele oil-feed, piston 2 moves down, and it is descending to drive punch 7, and stretched part 10 is shaped.Otherwise when piston 13 moves down, piston rod 17 moves down thereupon, distance rod 19,19 ', move in 19 ＂, 19 , toggle link 18,18 ', 18 ＂, 18 rotate, and flanging sill 12 is moved down, mould unclamps up and down, stretched part ejects.
The utility model also is provided with the governor motion that blank body is regulated the pressure-pad-force size, regulates nut 3 by rotating four, regulates screw mandrel 4 and moves up and down, and can regulate the size of four jiaos of pressure-pad-forces, four jiaos of total quadruplets.
The elbow-bar mechanism that novel hydraulic drawing press of the present utility model adopted can adopt single elbow-bar mechanism, dual-elbow-bar mechanism and overlap elbow-bar mechanism more according to different needs, all belongs to design protection domain of the present utility model.
