Description
Technical field
The present invention relates to a kind of high-speed fine press, be specifically related to a kind of high-speed fine press driving mechanism, belong to the metal forming machinery processing technique field.
Background technology
In the metal forming machinery processing industry, for high-speed blanking press, requiring has very high bottom dead centre precision, and traditional high-speed blanking press bottom dead centre adopts slider-crank mechanism more, and the slide block bottom dead centre can't dynamically be adjusted, and directly affects the quality and the die life of stamping parts.High-speed blanking press is because the rotating speed height must be taked bascule, and the traditional crank forcing press can only be in the vertical direction balance, and horizontal direction inertia force can't well be eliminated.For crank press, change stroke and need change parts such as bent axle, waste time and energy.Because the high-speed blanking press stroke is less, generally in 50mm, when mould need overhaul, because insufficient space, mould must be taken out and overhaul, way commonly used is to increase the slide block lifting device, relies on the increase hydraulic jack that whole lifting of entablature realized.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of high-speed fine press driving mechanism is provided, be in series by slider-crank mechanism, rhombus-mechanism, symmetrical elbow-bar mechanism, rely on the change of a position of the fulcrum of rhombus-mechanism to realize the adjustment of stroke and the dynamic adjustment of bottom dead centre, throw of crankshaft is strengthened, the rotation of the complete cycle of crank changed in certain angle swing, when crank has just been realized the fast lifting of slide block when bottom dead centre is got back to top dead-centre fast, save hydraulic lifting apparatus, promoted the reliability of lathe.Symmetrical elbow-bar mechanism is carried out the symmetric arrangement balanced controls at above-below direction, and symmetrical elbow-bar mechanism horizontal direction inertia force is offset automatically, and vertical direction relies on secondary slide block to realize vertical direction inertia equilibrium of forces.
The present invention realizes with following technical scheme: a kind of high-speed fine press driving mechanism, be in series by slider-crank mechanism, rhombus-mechanism, symmetrical elbow-bar mechanism, it is characterized in that: described slider-crank mechanism comprises crank (2), connecting rod (3), crank (2), connecting rod (3) are articulated in the A point, crank (2) is hinged at O point and frame (1), and the other end of connecting rod (3) and small slide block (4) are articulated in the B point; Described rhombus-mechanism is made of fork (5), fork (5 '), support bar (6) and support bar (6 '), fork (5) and support bar (6) are articulated in the D point, fork (5 ') and support bar (6 ') are articulated in D ' point, support bar (6), support bar (6 ') and frame (1) all are articulated in the H point, the H point can be adjusted up and down, realizes the change of slide block (10) stroke and the dynamic adjustment of bottom dead centre precision.
Described elbow-bar mechanism comprises connecting rod, toggle link, ball head connecting rod, reaches the slide block formation, the F point that a bit is hinged on frame of described toggle link, can rotate around the F point, an end of toggle link drives slide block by ball head connecting rod and pumps, the other end and slave connecting rod, secondary slide block Compositional balance mechanism.
Described connecting rod, toggle link and ball head connecting rod are articulated in the E point jointly, and described ball head connecting rod is connected with slide block by the G point.
Described slave connecting rod is connected with secondary slide block by the J point.
Described crank can be worked under weave mode, and the fast return top dead-centre is realized the slide block fast lifting.
Advantage of the present invention is: this driving mechanism is in series by slider-crank mechanism, rhombus-mechanism, symmetrical elbow-bar mechanism, rely on the change of a position of the fulcrum of rhombus-mechanism to realize the adjustment of stroke and the dynamic adjustment of bottom dead centre, throw of crankshaft is strengthened, the rotation of the complete cycle of crank changed in certain angle swing, when crank has just been realized the fast lifting of slide block when bottom dead centre is got back to top dead-centre fast, save hydraulic lifting apparatus, promoted the reliability of lathe.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a schematic diagram of the present invention:
Crank pivot angle schematic diagram under the work of Fig. 2 weave mode:
Among the figure 1, frame, 2, crank, 3, connecting rod, 4, small slide block, 5, fork, 6, support bar, 7, connecting rod, 8, toggle link, 9, ball head connecting rod, 10, slide block, 11, slave connecting rod, 12, secondary slide block.(because the symmetry of mechanism, symmetrical component illustrates no longer separately).
The specific embodiment
As shown in Figure 1: crank 2 is hinged on the frame 1 by pin joint O, drives crank 2 by servomotor and realizes rotation, and crank 2, connecting rod 3 and slide block 4 constitute slider-crank mechanism, and rotatablely moving of crank 3 is converted into slide block 4 pumping in frame 1.Connecting rod 3, small slide block 4, fork 5 and fork 5 ' be articulated in jointly B point, fork 5, fork 5 ', support bar 6 and support bar 6 ' formation rhombus-mechanism, support bar 6, support bar 6 ' and frame 1 be articulated in the H point, the B point of rhombus-mechanism pumps, the H point can be adjusted, and is locked during punching press.Connecting rod 7, connecting rod 7 ', toggle link 8, toggle link 8 ', ball head connecting rod 9, ball head connecting rod 9 ' and slide block 10 constitute symmetrical elbow-bar mechanism.By the change of H point upper and lower position, realize D point level to the right, the change on a left side, and then the reducing, increase of realization slide block 10 strokes.The adjustment amount of ordering as H very hour can effectively change the skew that slide block 10 bottom dead centres cause because of speed and temperature change.At the H point suitable reducing gear is set, utilizes servomotor just can realize the accurate control of bottom dead centre.Symmetry elbow-bar mechanism inertia force is in the horizontal direction cancelled out each other.Toggle link 8 is hinged on the F point of frame 1, can rotate around the F point.Toggle link 8 other ends and slave connecting rod 11, secondary slide block 12 Compositional balance mechanisms, balanced controls vertical direction inertia force, horizontal direction inertia force is eliminated automatically.
Among Fig. 2, when forcing press when weave mode is worked, the wobble area of crank is the hatching zone, when the needs fast lifting, connecting rod returns top dead-centre rapidly, thereby realizes the fast lifting of slide block.
