Abstract
The invention discloses a transmission gear of a pressing machine, which comprises an eccentric gear fixedly mounted on a mandril of the pressing machine, a first oscillating bar device and a second oscillating bar device. The multiple oscillating bar devices realize mechanical transmission with stable punching and quick returning properties so that the punching is performed in the operating stroke from an upper dead point to a lower dead point, the descending speed of a slide block is reduced, the punching is stable in the punching operation, so that the technological requirement on the precision punching is met; and the slide block returns from the lower dead point to the upper dead point, the returning speed is increased, the quick returning property is realized, and the efficiency of the pressing machine is improved.
Description
Technical field
The present invention relates to mechanical manufacturing field, relate in particular to the transmission device of forcing press.
Background technology
The transmission device of UP machine, comprise motor, motor is given flywheel by V belt with transmission of power, described flywheel is by being installed in the clutch-brake at flywheel place, drive the rotating shaft that flywheel connected, this rotating shaft drives the next stage gear wheel by the pinion on the axle, and described gear wheel is by driving the eccentric gear rotation with its pinion on same axle, drivening rod swing during the eccentric gear rotation drives slide block and moves up and down.Thus rotatablely moving of gear become the reciprocating motion of slide block, and then carry out stamping-out or other deformation technique, make workpiece.This kind of drive is simple, can not satisfy the requirement of press ram travel speed, thereby efficient can not perform to maximum.
Summary of the invention
It is steady that technical problem to be solved by this invention provides a kind of stamped workpieces process that makes, and the slide block opening speed is driver of press faster.
For solving the problems of the technologies described above, technical scheme of the present invention is: driver of press, comprise the eccentric gear that is fixedly mounted on the forcing press axle, and also comprise
The first fork device comprises the fork that is rotatably installed in the eccentric gear on the described forcing press axle, and described fork is hinged with rocking bar, and described rocking bar rotating hinge is connected on the rocker shaft, and another swinging end of described rocking bar is hinged with pull bar;
The second fork device, comprise the swinging block that is rotatably installed in the eccentric gear on the described forcing press axle, the clutch end of the hinged described pull bar of power intake of described swinging block, the clutch end of described swinging block are hinged with and drive the connecting rod that PRESS PLUNGER and slide block move up and down.
As a kind of optimized technical scheme, described rocker shaft is between described rocking bar power intake and clutch end, and described rocker shaft is fixed on the crossbeam.
Owing to adopted technique scheme, driver of press comprises the eccentric gear that is fixedly mounted on the forcing press axle, also comprises the first fork device and the second fork device.By multiple oscillating bar devices, reach punching press steadily and the machine driving of quickreturn characteristics, feasible impulse stroke from top dead-centre to bottom dead centre is carried out punching press, slide block down speed slows down gradually, in punching course punching press steady, satisfy the precision stamping technological requirement; From bottom dead centre to top dead-centre, the slide block backhaul, opening speed is accelerated, and has quickreturn characteristics, has improved the efficient of forcing press.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The embodiment of the invention illustrates the present invention in conjunction with the known running part of forcing press, in the hope of understanding the present invention better.As depicted in figs. 1 and 2, driver of press comprises: motor, be fixedly mounted on the small pulley 1 on the motor output shaft, drive installation is on the forcing press gear shaft and be provided with the flywheel 9 of trough of belt, flywheel 9 is connected as a single entity with press machine clutch 8, press machine clutch 8 is connected with forcing press gear shaft 11, by gear drive transmission of power is arrived eccentric gear 7, eccentric gear 7 is fixedly mounted on the forcing press axle, be installed in fork 2 and swinging block 5 on the described eccentric gear 7, the rocking bar 3 that is connected with described fork 2, hinged in the middle of the described rocking bar 3 with rocker shaft 14, described rocker shaft 14 is fixed on the crossbeam 15, with the pull bar 4 that described rocking bar 3 is connected with swinging block 5, the connecting rod 6 that is connected with described swinging block 5.
The operation principle of the embodiment of the invention: forcing press braking device 10 is at first thrown off, press machine clutch 8 engages, by being fixedly mounted on the polywedge bet of the transferring power of installing between small pulley 1 on the described motor output shaft and described flywheel 9 troughs of belt, drive flywheel 9 rotations, flywheel 9 is by press machine clutch 8 driving pressure machine gear shafts 11 mounted thereto, by the gear driven idler gear 12 on the forcing press gear shaft 11, idler gear 12 (two) and intermediate gear shaft 13 (two) one, drive eccentric gear 7 by intermediate gear shaft 13 again, the rotating band movable pendulum motion block 5 of eccentric gear 7 moves up and down, also drive simultaneously fork 2 swings, fork 2 drives swinging block 5 by rocking bar 3 and connecting rod 4 and moves up and down, be subjected to drivening rod 6 motions that move up and down of the swinging block 5 of three transfer motion powers, move up and down by described connecting rod 6 drive guide pillars and slide block, punching course with multi-bar linkage steadily and quickreturn characteristics is finished the Sheet Metal Forming Technology of precision stamping spare.The transmission that present embodiment is realized can make the slide block opening speed very fast, and the stamped workpieces process is steady, thus improve production efficiency and product quality.
