Abstract

The invention discloses a two-point toggle rod mechanism. With the adoption of the two-point toggle rod mechanism, a slider has longer retention and dwell time at a bottom dead center through a unique running curved line of the two-point toggle rod mechanism. The two-point toggle rod mechanism has the characteristics of being beneficial for plastic deformation of materials, so that the product quality can be improved, and the materials are saved.

Description

A kind of two point elbow-bar mechanism
Technical field
The invention discloses a kind of new two point elbow-bar mechanism.
Background technology
In the existing technology, as light-alloy (magnesium, aluminium, titanium) and high-tension material punching press on universal machine tools, because the particularity of these materials needs repeatedly punching press and heating just can finish, its complex process, efficient is low; The machining feature of its requirement requires slide block to have than long residence time at bottom dead centre, to meet light-alloy and high-tension material characteristic of plastic deformation.
Summary of the invention
The present invention is directed to above-mentioned defective, 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 long time of staying.The plastic deformation characteristics that are conducive to light-alloy and high-tension material.
The technical solution used in the present invention is for this reason: motor of the present invention (1) drives flywheel (3) by belt pulley (2) and rotates, 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 installed in crank throw (6) by key and goes up and drive crank throw (6) circular motion, crank throw (6) is gone up while installing connecting rods (7) and drive link (7) swings up and down, connecting rod (7) drives upper elbow lever (8), lower elbow lever (9) swing, and lower elbow lever (9) drives slide block and 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 present invention by the operation curve of elbow-bar mechanism uniqueness, makes slide block at bottom dead centre be arranged the long stop dwell time.The plastic deformation characteristics that are conducive to material.So just can improve the quality of products, save material.
Description of drawings
Fig. 1,2,3 is structural representation of the present invention.
Fig. 4 is operation curve figure.
Wherein: 1 is that motor, 2 is ball screw for lower elbow lever, 10 for upper elbow lever, 9 for gear wheel, 6 crank throws, 7 connecting rods, 8 for gear shaft, 5 for flywheel, 4 for belt pulley, 3.
The specific embodiment
Motor 1 of the present invention drives flywheel 3 by belt pulley 2 and rotates, 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 installed on the crank throw 6 by key and drives crank throw 6 circular motion, while installing connecting rods 7 and drive link 7 swing up and down on the crank throw 6, connecting rod 7 drives upper elbow lever 8, lower elbow lever 9 swings, and lower elbow lever 9 drives slide block and 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.
The course of work of the present invention is: drive belt pulley 2 by motor 1, driving flywheel 3 by V belt rotates, flywheel is given gear shaft 4 by clutch with power transmission, gear shaft 4 drives gear wheel 5 and synchronizedly runs, gear wheel 5 is installed on the crank throw 6, connect by key, to drive that crank throw 6 is made circular motion and connecting rod 7 is installed on the crank throw 6, connecting rod 7 swings up and down, drive upper elbow lever 8, lower elbow lever 9 is swung, and 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.
Crank throw 6 continues rotation and slide block rests on bottom dead centre substantially when slide block runs to BBC, and when crank throw 6 continues rotation, slide block begins backhaul.Thereby realized the function in the bottom dead centre stop.
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. two point elbow-bar mechanism, it is characterized in that, motor (1) drives flywheel (3) by belt pulley (2) and rotates, 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 installed in crank throw (6) by key and goes up and drive crank throw (6) circular motion, crank throw (6) is gone up while installing connecting rods (7) and drive link (7) swings up and down, connecting rod (7) drives upper elbow lever (8), lower elbow lever (9) swing, and lower elbow lever (9) drives slide block and 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.
