Description

The stroke adjustment retaining mechanism of multi-link lever press
Technical field
The present invention relates to a kind of press machine, in particular to a kind of multi-link lever press.
Background technique
In the production design work of existing multi-link lever press, there is the demand to stroke adjustment function, according to toggle link The characteristic of itself, the variation of relative position and size can change final stroke between leverage, wherein changing upper elbow lever upper end Position with fuselage tie point is a kind of commonplace tune travel schedule.But in the process of knuckle-lever press stamping products In, upper elbow lever is subjected to very big power, this requires lock Strok mechanism in the case where bearing larger pressure condition, can reliably meet its function Energy.In existing technology, lock Strok mechanism still can thoroughly be locked at work after not can guarantee press machine long-time use Dead stroke, this just integrally causes influence to stroke adjustment, it is made to lack practicability and reliability.
Summary of the invention
The object of the present invention is to provide a kind of stroke adjustment retaining mechanism of knuckle-lever press, it is easy to use and utilize high pressure The characteristic that oil keeps pressure stable makes locking device not lose effect because of part deformation, to improve tune Strok mechanism Practicability, reliability.
The technical scheme is that: the stroke adjustment retaining mechanism of multi-link lever press, including the elbow being fixed on fuselage Linkage, the elbow-bar mechanism include the connecting rod that one end is hinged on crankshaft, and the other end of connecting rod is hinged with upper elbow lever and lower elbow Bar, the lower elbow lever are hinged on sliding block, and described upper elbow lever one end is hinged on connecting rod, and the other end of upper elbow lever is hinged on stroke On regulating mechanism, the stroke control mechanism includes the mandrel being mounted on fuselage, and being set on the mandrel can be along mandrel axis To the movable block of sliding, the retaining mechanism that movable block can be locked on mandrel, the locking machine are installed on the movable block Structure includes the oil cylinder and piston being arranged in movable block, and the piston contradicts on the surface of movable block, the piston and oil cylinder it Between form hydraulic fluid chamber, internal galleries are equipped in the oil cylinder, the internal galleries are connected with the hydraulic fluid chamber.
When the present invention works normally, upper elbow lever upper end is connected with a movable block, and movable block can by being sleeved on mandrel It slides axially along mandrel, installation oil cylinder on movable block, when locking stroke, hydraulic oil generates high pressure and withstands piston, the fixation of piston Fixation of the movable block with respect to mandrel is realized, to reach fixed journey system;When needing to adjust stroke, make oil cylinder pressure release, eliminates and live The clamping force to mandrel is filled in, movable block can prolong the movement of mandrel axis direction to change slider stroke, compared with prior art, originally Advantageous effect of the invention is that the present invention is completed by the position of adjusting movable block to the upper elbow lever position being hinged on movable block The adjusting set, thus realize the adjusting to the stroke of a press, characteristic easy to adjust, and keeping pressure stable using high pressure oil So that locking device will not lose effect because of part deformation, to improve the practicability for adjusting Strok mechanism.The present invention is available During knuckle-lever press stamping products.
As a further improvement of the present invention, screw rod is provided through on the fuselage, the screw rod protrudes into the one of fuselage End is connected on movable block, can be more convenient sliding motion block.
As a further improvement of the present invention, one end that the screw rod protrudes into fuselage is fixedly connected with jacking block, the jacking block It is fixed on movable block, the stress surface of movable block can be increased, so that push-and-pull effect is more preferable.
As a further improvement of the present invention, dial is housed on the screw rod, it is ensured that the synchronism of stroke adjustment, Improve the precision adjusted.
As a further improvement of the present invention, it is equipped with sealing ring in the oil cylinder, can prevent hydraulic oil from revealing.
As a further improvement of the present invention, the movable block surface is equipped with copper sheathing, can protect movable block, avoids and core Abrasion is generated between axis.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is partial enlarged view at A in Fig. 1 of the present invention.
Wherein, 1 lower elbow lever, 2 connecting rods, 3 upper elbow levers, 4 movable blocks, 5 jacking blocks, 6 screw rods, 7 mandrels, 8 fuselages, 9 copper sheathings, 10 is living Plug, 11 oil cylinders, 12 sealing rings, 13 hydraulic fluid chambers, 14 internal galleries.
Specific embodiment
The following further describes the present invention with reference to the drawings:
The stroke adjustment retaining mechanism of multi-link lever press as shown in Figs. 1-2, including the toggle link machine being fixed on fuselage 8 Structure, elbow-bar mechanism include the connecting rod 2 that one end is hinged on crankshaft, and the other end of connecting rod is hinged with upper elbow lever 3 and lower elbow lever 1, under Toggle link 1 is hinged on sliding block, and 3 one end of upper elbow lever is hinged on connecting rod 2, and the other end of upper elbow lever 3 is hinged on stroke control mechanism On, stroke control mechanism includes the mandrel 7 being mounted on fuselage 8, and being set on mandrel 7 can move in axial sliding along mandrel 7 Block 4, the retaining mechanism that can be locked at movable block 4 on mandrel 7 is equipped on movable block 4, and retaining mechanism includes being arranged in movement Oil cylinder 11 and piston 10 in block, the conflict of piston 10 form hydraulic fluid chamber between the surface of movable block 4, piston 10 and oil cylinder 11 13, oil cylinder 11 is interior to be equipped with internal galleries 14, and internal galleries 14 are connected with hydraulic fluid chamber 13, are provided through screw rod on fuselage 8 6, one end that screw rod 6 protrudes into fuselage 8 is connected on movable block 4 by jacking block, dial, the oil in oil cylinder 10 are housed on screw rod 6 Slot is equipped with sealing ring 11, and movable block surface is equipped with copper sheathing 9.
When work, hydraulic oil generates high pressure and withstands piston 10, and the fixation of piston 10 realizes movable block 4 with respect to mandrel 7 It is fixed, to achieve the purpose that fixed journey system, realize the locked function of stroke;When stroke needs to adjust, oil pump off-load, " folder Tightly " effect disappears, and movable block 4 restores left and right and moves freely ability, is pushed with screw rod 6, can be moved to designated position realization and refer to Determine the adjusting of stroke, and the travel synchronization of the right and left can be made to adjust by dial, precision is high.The mechanism is by adding Pressure-off-load operation switches press machine very easily in stroke adjustment and fixed state, while utilizing high pressure oil The characteristic for keeping pressure stable makes retaining mechanism not lose effect because of part deformation.
