Abstract
A six-bar linkage curved device includes an eccentric crankshaft (2) that is installed on the pressing machine, one end of a connecting rod (3) is linked with the eccentric crankshaft, the other end of the connecting rod is linked with a slider (4) that is installed in the slot or track, the device is characterized in that the eccentric crankshaft is linked with one end of a rocker (1), and the other end of the rocker is articulated in the press body.
Description
Technical field
The utility model relates to a kind of linkage mechanism, particularly a kind of coupler curve type six bar mechanism that is applicable to press machine.
Background technique
The power transmitting mechanism of common pressure machine is made of crankshaft-and-connecting-rod, this mechanism drives crankshaft rotating by the big flywheel of rotation on press machine, the bent axle of rotation drivening rod again swings, thereby driving the slide block be connected the connecting rod lower end moves up and down and finishes stamping process, one week of crankshaft rotating returns upper dead center by upper dead center to lower dead centre, and its movement velocity characteristic curve is a sinusoidal curve, this curve shows that its acceleration is descending, and is ascending again.Yet this speed characteristics can not adapt to technology lower and uniform working stroke requirements of speed to speed such as deep drawn, cold hobbing.
The model utility content
Technical problem to be solved in the utility model be to provide a kind of simple and reasonable, the operating time prolongs relatively, the mould contact velocity is slow, noise is low, vibrations are little, the coupler curve type six bar mechanism of long service life, to overcome deficiency of the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of coupler curve type six bar mechanism, comprise the eccentric crankshaft that is arranged on the press machine, connecting rod one end and eccentric crankshaft are hinged, the connecting rod the other end is hinged with the slide block that is arranged in slide block guide groove or the guide rail, its structure characteristic is that eccentric crankshaft and rocking bar one end are hinged, and the rocking bar the other end is hinged on the fuselage of press machine.
The line of the rotating center of above-mentioned eccentric crankshaft and rocking bar and eccentric crankshaft hinged place constitutes man type with the rotating center of eccentric crankshaft with the line of connecting rod and eccentric crankshaft hinged place.
The needs that the utility model can satisfy pull and stretch speed and boost productivity, it is compared with common crankshaft-link rod press machine has following feature: the slide block that the connecting rod lower end is connected is done at the uniform velocity mobile in long working stroke, adapt to technology lower and uniform working stroke requirements of speed such as deep drawn, cold hobbing to speed, slow with the mould contact velocity; The impact of mould and workpiece when also having reduced the work beginning simultaneously, shakes all smallerly at its noise, can effectively prolong working life of mould; It high moment of torsion occurs easily when distance slide block lower dead centre higher position, help realizing the deep-draw and the deep-draw processes of slab; It is low and even at long working stroke medium velocity, has satisfied the needs of the reasonable drawing speed of plate, has improved the quality of drawing part; It has anxious time, fireballing characteristic in backhaul, so the working stroke time of press machine prolongs relatively, guaranteed the feeding time, has avoided the mechanism hand interference, helps the automation line; And do not exceed under the situation of sheet material Limit Drawing speed 25m/min in assurance, multi-link lever press allows the higher press number of strokes, can increase work efficiency more than 50%.
Description of drawings
Fig. 1-Fig. 4 is the utility model one embodiment's working procedure structural representation.
Fig. 5 is the user mode structural representation of the utility model on press machine.
Fig. 6 is a performance chart of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 5, this coupler curve type six bar mechanism, comprise the eccentric crankshaft 2 that is arranged on the press machine, connecting rod 3 one ends and eccentric crankshaft 2 are hinged, connecting rod 3 the other ends are hinged with the slide block 4 that is arranged in slide block guide groove or the guide rail, slide block 4 joins with mould, and eccentric crankshaft 2 is hinged with rocking bar 1 one ends, and rocking bar 1 the other end is hinged on the fuselage of press machine.The line of the rotating center of eccentric crankshaft 2 and rocking bar 1 and eccentric crankshaft 2 hinged places constitutes man type with the rotating center of eccentric crankshaft 2 with the line of connecting rod 3 and eccentric crankshaft 2 hinged places, sees Fig. 1-Fig. 4; For balance-impact power, rocking bar 1, eccentric crankshaft 2, connecting rod 3 and slide block 4 can be arranged in pairs on the press machine, see Fig. 5.
Referring to Fig. 6, can learn from its performance chart: the utility model stand under load characteristic is good, and the slide block stress curve performance of being determined by driving parts intensity is also than higher.Among Fig. 6, S represents displacement, the V representation speed.
Claims (3)
