Fig. 5 provides the driving Slipper cross sectional representation of the utility model press ram drive unit.In Fig. 5, be equipped with on another cardinal extremity of transmission toggle link (8) and drive ball seat (16).
Driving ball seat (16) can be to make one all-in-one-piece (not providing among the figure), is assemblied in rotationally on another cardinal extremity of transmission toggle link (8).The driving ball seat of this structure rotates assembling and drives ball seat (16), the drive disk assembly Contact Transmission that makes unworn ball seat sphere and be in contact with it after the sphere of part driving ball seat weares and teares.Can reduce the time that drives ball seat of changing, prolong the service life of the drive disk assembly that is in contact with it.
Drive ball seat (16) and also can make one split typely, can be inlaid in respectively on the upper surface, lower surface of another cardinal extremity of transmission toggle link (8).
In order to be fit to actuator chamber (18) the internal structure space of slide block (17), as shown in Figure 5, present embodiment is preferential to adopt split type driving ball seat, promptly is embedded with driving ball seat (1601) respectively on the upper surface of another cardinal extremity of transmission toggle link (8), lower surface, drives ball seat (1602) down.
Corresponding going up drives ball seat (1601) in the actuator chamber (18) of slide block (17), under drive ball seat (1602) and be respectively fitted with fixed block (2101) and following fixed block (2102), between last fixed block (2101) and last driving ball seat (1601), be equipped with abrading block (2001), be equipped with abrading block (2002) down down between fixed block (2102) and the following driving ball seat (1602), last driving ball seat (1601), the sphere that drives ball seat (1602) down respectively with last abrading block (2001), following abrading block (2002) coincide and assembles, and can be in last abrading block (2001), slide relatively between the break-in face of following abrading block (2002).
Last driving ball seat (1601) and the following width that drives ball seat (1602) are slightly less than the width of slide block (17).Thereby the impetus that has guaranteed the power that transmission toggle link (8) transmission is come acts on the middle part of slide block (17) all the time, and slide block can not produce eccentric load on (17).Solved existing forging press slide block drive link in descending process and can produce eccentric load and the large tonnage pressing machine drive link can be subjected to impulsive force and the higher rigidity problem will be arranged slide block.
Go up fixed block (2101) for one and lean assembling by the gap adjustment bolt (22) that is assemblied in slide block (17) upper surface.When sphere that drives ball seat (16) and last abrading block (2001), when descending abrading block (2002) to produce wearing clearance, adjusting bolt (22) by the gap rotates at any time, fixed block in the driving (2101), last abrading block (2001) contact with the sphere that drives ball seat (16), to compensate the deviation of bringing because of wearing and tearing.
Following fixed block (2102) is by the supports support of the actuator chamber that is assemblied in slide block (17) (18) bottom.
This support member can be a height adjustable back-up block, also can be the back-up block of other structures.
Piston (23) support assemblies of the hydraulic jack that is (25) that the present embodiment support member adopts.
As shown in Figure 5, the piston (23) that leans down the hydraulic jack (25) of fixed block (2102) is in the hydraulic chamber (24) that is assemblied in oil cylinder (25), and oil cylinder (25) is fixedly mounted in actuator chamber (18) bottom of slide block (17).For the size of the actuator chamber (18) that is fit to slide block (17), guarantee that the pressure loading that assembling facility and oil cylinder bear is even, the hydraulic chamber (24) of oil cylinder (25) is designed to 2 hydraulic chamber that are in series, be hydraulic chamber (2401), (2402), piston (2301), piston (2302) correspondence respectively are assemblied in hydraulic chamber (2401), (2402), and can in hydraulic chamber, move, support leaning down fixed block (2102).
In the cylinder body of oil cylinder (25), offer the oil duct (26) that is communicated with hydraulic chamber (24).
As Fig. 5, shown in Figure 6, corresponding oil duct (26) is equipped with shutoff gate gurgle valve (27) outside the cylinder body of oil cylinder (25), in the valve pocket (28) of shutoff gate gurgle valve (27), be provided with the spool (29) of shutoff oil duct, spool can be provided with sealing ring on (29), and rotary spool (29) can carry out shutoff with oil cylinder oil duct (26) or open.
In Fig. 6, on the valve body of shutoff gate gurgle valve (27), be respectively equipped with the priming valve (30) and the gate gurgle valve (31) that are communicated with valve pocket (28).
Priming valve (30) is made up of valve body (32) and the oiling oil duct (33) offered on valve body (32), is provided with the unidirectional valve of being made up of spring (34) and valve ball (35) of opening in the oil duct (33) refueling.
By priming valve (30), shutoff gate gurgle valve valve pocket (28), oil cylinder oil duct (26) can be unidirectional the hydraulic oil that in oil cylinder hydraulic chamber (2401), (2402), injects predetermined oil pressure.During operation, workpiece is carried by hydraulic oil the impulsive force that slide block (17) produces, and has played buffering and absorption, the steady noiselessness of forcing press forging and pressing operation.
Gate gurgle valve (31) is formed the valve ball (39) that draining screw (38) is installed and is leaned by this draining screw (38) by valve body (36) and the draining oil duct (37) offered in draining oil duct (37) on valve body (36).Rotation draining screw (38) relies on the valve ball (39) lean to carry out shutoff or open draining oil duct (37).
The utility model releases the hydraulic oil in oil cylinder hydraulic chamber (2401), (2402) when vexed car fault occurring, make between slide block (17) and transmission toggle link (8) and produce the gap, and power-driven system just can drive slide block (17) and get back to upper dead center position; Inject the hydraulic oil of predetermined oil pressure then in oil cylinder hydraulic chamber (2401), (2402), lathe just recovers operate as normal.Therefore, solve vexed car fault rapidly, reliably.
As Fig. 3, shown in Figure 5, operation principle of the present utility model is: after the driving force of motor (1) passes to flywheel (5) by belt (4) transmission, through flywheel driving shaft (7), travelling gear (14) on the flywheel driving shaft (7), a reduction gearing (13) that is meshed with travelling gear (14) is delivered on the bent axle (12), bent axle (13) rotates, the crank throw (11) of the off-centre of bent axle (13) is along a circular path rotation with eccentric arm, a cardinal extremity that makes the drive link (10) that connects crank throw (11) and transmission toggle link (8) drive transmission toggle link (8) moves back and forth on an arc road, another cardinal extremity that is supported on the lever transmission toggle link (8) on the frame (2) also moves back and forth on a predetermined arc road, the sphere of the driving ball seat (16) on this cardinal extremity is in last abrading block (2001), slide relatively between the break-in face of following abrading block (2002), drive slide block (17) simultaneously and guiding rising and decline in a predetermined stroke by slide block guide rail (19).
As Fig. 2, shown in Figure 7, the back shaft (15) that transmission toggle link (8) is supported on the frame (2) is an eccentric shaft, the brake coupling (40) of this back shaft (15) one ends assembling, and this brake coupling (40) is controlled the rotation of back shaft (15) or is stopped.Back shaft (15) other end is equipped with and drives the parts that back shaft (15) rotates.
The brake coupling (40) of assembling back shaft (15) one ends comprises a frictional disk (44) and a brake disc (41) that is installed on the frame (2) that is installed on the back shaft (15), one presses dish (45) and by mounting rod (43), tripping spring (42) frictional disk (44) is pressed with brake disc (41) and contact braking, and this brake coupling (40) comprises that also will press the disengagement oil cylinder (46) that dish (45) is thrown off frictional disk.
