Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of noncircular gear transmission device that can control the slide block movement speed of punching apparatus.
Background technique
Punching apparatus is a kind of press work equipment that is applied to sheet-metal press working, punching, blanking, crooked flanging and shallow stretching, and stamping part all is widely used in industries such as wrist-watch, toy, tableware, telecommunication apparatus, instrument and apparatus, motor, electrical equipment, tractor and automobile making, haberdashery and hardware, wireless.
Punching apparatus be a kind of be the transmission device of groundwork mode with punching press power, generally include motor, clutch, flywheel, connecting rod, bent axle and slide block.During work, motor drives flywheel and clutch motion by drivign belt, and clutch drives bent axle by connecting rod, and the motion of bent axle drives slide block workpiece is done manual work.What connecting rod produced in this process is simple harmonic motion, the reciprocatory motion that bent axle produces, and slide block generally is moving up and down of Vertical direction, the workpiece that need process is located in the lower dead center place of slide block movement.Because motor generally is to drive crankshaft operation with uniform velocity, the speed and the time of an angle of the every rotation of bent axle are identical, and the distance of slider displacement also can be identical simultaneously.Therefore crankshaft rotating angle and the relativeness of slide position are with regard to the displacement stroke as sinusoidal curve.Because the slide block practical function only is the place, final position of its motion in the zone of workpiece, be that its operation point only is the trough place of sinusoidal curve bottom, slide block is all the same long in the time that the no working state of top dead center and working state in lower dead center stop, the workpiece that needs processing relatively, slide block under fast speeds punching press on workpiece, can cause the temperature of workpiece to raise, and then workpiece with this heat transfer to mould, make mould generation thermal expansion, shortened the working life of mould, increased the number of times that repairs a die, also reduced manufacturing efficiency, therefore, thereby how to have avoided that ram speed is too fast to be caused workpiece to heat up mould is exerted an influence, being urgent problem in the work, also is the key of increasing work efficiency and need overcome.
The model utility content
For the slide block of control punching apparatus in the speed of operation point, the utility model provides a kind of noncircular gear transmission device that can produce variable motion, the not equidistant principle of circles such as utilization realizes reducing the speed of slide block in the operation point, reaches and increases work efficiency, and prolongs the effect of die life.Concrete scheme is as follows: a kind of gear drive that reduces ram speed in the punching apparatus, comprise motor, belt pulley, flywheel, clutch, bent axle and slide block, wherein motor drives flywheel by belt pulley, flywheel drives clutch, bent axle drives slide block, it is characterized in that, between described clutch and the bent axle speed change gear is installed.
Another preferred version of the present utility model: described speed change gear comprises the driving gear and the driven gear that is installed on the bent axle on the output shaft that is installed in clutch, driving gear and driven gear engagement, the immovable point of described driving gear and output shaft does not overlap with the center of circle of driving gear, the immovable point of described driven gear and bent axle and the center of circle of driven gear be center of gravity not, and described driving gear is the same with ring gear diameter and the immovable point position is identical.
Another preferred version of the present utility model: described driving gear and had two and be meshing with each other respectively by gear.
Another preferred version of the present utility model: the immovable point of the immovable point of described driving gear and output shaft and driven gear and bent axle lays respectively at 1/3 and close circle centre position of its radius.
This programme utilizes two to be meshing with each other and not to be to be the gear of turning point with the center of circle, realizes the output of different rotating speeds, reaches and reduces the operating time of slide block on workpiece, has prolonged the working life of mould, has improved manufacturing efficiency.Select the different fixing point of output shaft, bent axle and gear, can realize the requirement of slide block friction speed.

Embodiment
As shown in Figure 1, motor 1 work drives belt pulley 2 rotations, belt pulley 2 drives flywheel 4 rotations by belt 3, flywheel 4 drives clutch 5 rotations, and the output shaft 6 of clutch 5 is connected with bent axle 8 by gear drive, and bent axle drives 7 pairs of workpiece of slide block by slide block connecting rod 10 and does manual work, and finishes entire work process, wherein gear drive uniform motion that clutch is transmitted is transformed into non-uniform movement and passes to slide block, thereby realizes the variation of slide block relative velocity.
The gear drive of this programme, be included in two driving gears 11 are installed on the output shaft 6 of clutch, two driven gears 9 are also installed in the corresponding position on bent axle 8, output shaft 6, the immovable point 12 of bent axle 8 and driving gear and driven gear is not positioned at the center of circle of gear, but certain position of staggering, work as output shaft like this, when bent axle rotates, the center of circle of driving gear 11 and driven gear 9 is just around output shaft, the immovable point 12 of bent axle and driving gear and driven gear moves in a circle, this moment driving gear, the driven gear excircle is just along with output shaft, the rotation of bent axle forms a sinusoidal curve figure of fluctuation as shown in Figure 4, gear side from the immovable point farthest is located in sinusoidal wave summit, and is located in sinusoidal wave minimum point from the nearest gear side of immovable point.The driving gear of output shaft is consistent on mounting point and size shape with the driven gear on the bent axle, and the slide block connecting rod 10 that connects slide block is installed between two driven gears.
When two driving gear rotations on the output shaft, drive two driven gear rotations on the bent axle, rationally adjust the engaging position of driving gear and driven gear, driving gear and driven gear are meshed in movement process closely, realize the continuous operation of slide block.Shown in Fig. 2,3; promptly when driving gear fixed distance point limit farthest on the output shaft is positioned at driving gear and driven gear contact points farthest; driven gear fixed distance point limit farthest is positioned at the contact points place of driving gear and driven gear on the bent axle; just need to keep the distance protection between driving gear and the driven gear immovable point constant; though so just can form driving gear and driven gear and be not with the center of circle is support motion, also can form tight contact between the two.
Shown in Fig. 2,3, when the immovable point of the driving gear on the output shaft 6 during, the path lengthening of rotation this moment away from the contact points of driving gear and driven gear, the movement velocity of slide block that just slowed down relatively, thus make slide block act on time decreased on the workpiece.When the immovable point of the driving gear on the output shaft during near the contact points of driving gear and driven gear, this moment, the path of rotation shortened, and had just accelerated the movement velocity of slide block relatively, and this moment, slide block was positioned at top dead center, promptly away from an end of workpiece.In whole work cycle, just formed like this, slide block speed when operative workpiece slows down, and when top dead center moves, speed up, for entire work process, the time that consumes is still the same, but but produced different effects, reached the purpose that prolongs die life, enhances productivity.
The immovable point of the diameter of change gear and gear and output shaft, bent axle can be realized different operating speed.The immovable point of output shaft and bent axle and gear being located at radius 1/3 place of gear and near the center of circle one side, can strengthening the control ability of slide block greatly, make slide block can realize the punching press purpose, is not again quality problems to occur.
