Abstract

The utility model discloses a two-point toggle rod mechanism. A motor (1) drives a flywheel (3) to rotate through a belt wheel (2), the flywheel (3) drives a gear shaft (4) through a clutch, the gear shaft (4) drives a big gear (5) to synchronously move, the big gear (5) is arranged on a crank (6) through a key and drives the crank (6) to carry out circular motion, the crank (6) is simultaneously provided with a connecting rod (7) and drives the connecting rod (7) to vertically swing, the connecting rod (7) drives an upper toggle rod (8) and a lower toggle rod (9) to swing, and the lower toggle rod (9) drives a sliding block to vertically move. Through the unique motion curve of the toggle rod mechanism, the sliding block is made to have a long staying and dwell time at a lower dead point. The advantage of facilitating the plastic deformation of materials is achieved. Therefore, product quality can be improved, and materials are saved.

Description

A kind of two point elbow-bar mechanism
Technical field
The utility model discloses a kind of new two point elbow-bar mechanism.
Background technology
In existing technology, as light-alloy (magnesium, aluminium, titanium) and high-tension material punching press on universal machine tools, because needing Multi-step forming and heating, the particularity of these materials just can complete, its complex process, and efficiency is low; The machining feature of its requirement requires slide block to have than long residence time at bottom dead centre, to meet the characteristics of light-alloy and high-tension material plastic deformation.
The utility model content
The utility model is for above-mentioned defect, and purpose is to provide a kind of Quick return elbow-bar mechanism, and its speed in the nominal pressure stroke range is very slow and at bottom dead centre, arranged the longer time of staying.The plastic deformation characteristics that are conducive to light-alloy and high-tension material.
The technical solution adopted in the utility model is for this reason: motor of the present utility model (1) rotates by belt pulley (2) flywheel driven (3), flywheel (3) is by clutch drive gear axle (4), gear shaft (4) drives gear wheel (5) and is synchronized with the movement, gear wheel (5) is arranged on crank throw (6) by key and goes up and drive crank throw (6) circular motion, the upper installing connecting rods (7) simultaneously of crank throw (6) drive link (7) swing up and down, connecting rod (7) drives upper elbow lever (8), lower elbow lever (9) swings, and lower elbow lever (9) band movable slider moves up and down.
Described lower elbow lever (9) is connected with ball screw (10) by pin, and ball screw (10) and slide block are connected.
A kind of two point elbow-bar mechanism of the utility model, by the operation curve of elbow-bar mechanism uniqueness, make slide block, at bottom dead centre, be arranged the longer stop dwell time.The plastic deformation characteristics that are conducive to material.So just can improve the quality of products, save material.
The accompanying drawing explanation
Fig. 1,2,3 is the utility model structural representation.
Fig. 4 is operation curve figure.
Wherein: 1 be motor, 2 for belt pulley, 3 for flywheel, 4 for gear shaft, 5 for gear wheel, 6 crank throws, 7 connecting rods, 8 for upper elbow lever, 9 for lower elbow lever, 10 be ball screw.
The specific embodiment
Motor 1 of the present utility model rotates by belt pulley 2 flywheel drivens 3, flywheel 3 is by clutch drive gear axle 4, gear shaft 4 drives gear wheel 5 and is synchronized with the movement, gear wheel 5 is arranged on crank throw 6 by key and drives crank throw 6 circular motion, on crank throw 6, while installing connecting rods 7 drive link 7 swing up and down, connecting rod 7 drives upper elbow lever 8, lower elbow lever 9 swings, and lower elbow lever 9 band movable sliders move up and down.
Described lower elbow lever 9 is connected with ball screw 10 by pin, and ball screw 10 and slide block are connected.
The course of work of the present utility model is: by motor 1, drive belt pulley 2, by V belt flywheel driven 3, rotate, flywheel by clutch by power transmission to gear shaft 4, gear shaft 4 drives gear wheel 5 and synchronizedly runs, gear wheel 5 is arranged on crank throw 6, by key, connect, to drive that crank throw 6 circles and connecting rod 7 is arranged on crank throw 6, connecting rod 7 swings up and down, drive upper elbow lever 8, lower elbow lever 9 swings, lower elbow lever 9 is connected with ball screw 10 by pin, thereby moving up and down of lower elbow lever 9 driven to ball screw 10, ball screw 10 is connected by fixed form with slide block, thereby slide block moves up and down.
When slide block runs to BBC, crank throw 6 continues rotation and slide block rests on bottom dead centre substantially, and when crank throw 6 continues rotation, slide block starts backhaul.Thereby realized the function stopped at bottom dead centre.
The contrast of crank press stroke curve and two point elbow-bar mechanism curve (S1 (a) is that toggle link stroke curve, S3 (a) are the crank press curve).

Claims (2)

1. a two point elbow-bar mechanism, it is characterized in that, motor (1) rotates by belt pulley (2) flywheel driven (3), flywheel (3) is by clutch drive gear axle (4), gear shaft (4) drives gear wheel (5) and is synchronized with the movement, gear wheel (5) is arranged on crank throw (6) by key and goes up and drive crank throw (6) circular motion, the upper installing connecting rods (7) simultaneously of crank throw (6) drive link (7) swing up and down, connecting rod (7) drives upper elbow lever (8), lower elbow lever (9) swings, and lower elbow lever (9) band movable slider moves up and down.
2. a kind of two point elbow-bar mechanism according to claim 1, is characterized in that, described lower elbow lever (9) is connected with ball screw (10) by pin, and ball screw (10) and slide block are connected.
