Technical field
The utility model relates to the press technologies field, specifically refers to a kind of four-point press ram mould height adjusting device.
Background technology
Forcing press is extensively used in field of machining, and a kind of four-point forcing press is wherein arranged, because the slide block good stability, it is strong to bear the unbalance loading ability, and the four-point forcing press all adopts welded-steel plate construction.Slide block movement is steady, and precision is high, and can keep for a long time precision constant.The machine mainly is applicable to the operations such as the punching and blanking, bend tension of the large shape plate of wide format; be widely used in the industries such as automobile, tractor, aviation, washing machine, motor, can fill band air cushion or stretching hydraulic die cushion and photo-electric personal safety protector according to user's requirement of ordering goods.The slide-action die height adjusting device of four-point forcing press of the prior art is that single-point is dull mostly; that is to say; the four-point forcing press comprises four adjusting levers; each adjusting lever is singly connected with an adjustment motor; when needs adjustment slide-action die is high; must be by control circuit or four adjustment motor synchronous workings of remote controller control; the slide-action die height of finding the four-point forcing press of this structure in the practical operation is difficult to keep synchronism when adjusting, and often can occur because motor is out of step and causes the phenomenon that going up and down with different paces of adjusting lever causes.Slide-action die height adjusting device of the prior art only has adjustment component simultaneously, less than the high in real time display unit of mould, can't well guarantee to adjust precision when carrying out adjusting operation.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of synchronism good, and adjust the high four-point press ram mould height adjusting device of precision.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of four-point press ram mould height adjusting device, it comprises slide block, adjusting lever, electro-motor and guide rail, slide block and guide rail are slidingly matched, described adjusting lever is four, lower end and the slide block of each adjusting lever are fixed, it also comprises the worm gear case group, gear-box, the high indicator of mould and decoder, described gear-box is provided with an input rotating shaft and four output revolving shafts that rotate synchronously, described electro-motor only has one, the rotating shaft of described electro-motor links to each other with input rotating shaft on the gear-box, all be connected with worm screw on four output shafts on the gear-box, described worm gear case group is four, is connected with an adjusting lever on each worm gear case group, and described four worm gear case groups are connected one to one with worm screw on four output shafts, the high indicator of described mould is installed in four worm screws any one, and described decoder is electrically connected with the high indicator of mould.
After adopting above structure, the utlity model has following advantage: utilize the interior saw-tooth thread adjusting lever of four groups of worm gear cases that electrical motor driven is fixed in slide block to rotate, thereby realize the up and down adjustment action of slide block.Motor output shaft connects by torque force limiting device with gear-box, can effectively protect the motor can overload work.Left and right sides gear is fixed on two connecting axles in front and back in the gear-box, is incorgruous rotation during transmission, thereby determines the transmission direction of four groups of worm gear cases, makes the direction of rotation of adjusting lever consistent.Connecting axle all connects with shaft coupling with worm gear case with gear-box, gear-box, but need increase the gear that the effect of connection diaxon is arranged at the high indicator decoder of mould built-up section, by gear pair and turn to reductor to connect respectively the high indicator of mould and decoder, through reasonable gear ratio calculation, reach the synchronous and interlocking of the high indicator of mould and decoder.Namely provide simultaneously the equal high signal of mould to controller, when asynchronous such as two signals, adjust action and stop at once.The high indicator of mould can arrange bound numerical value, belongs to mechanical positioning device; Decoder can be set bound numerical value in controller, belong to the electronic type positioner.The dual mode location purpose that all can reach capacity plays the dual fail-safe effect.Gear-box part and all airtight protections of the high indicator decoder of mould built-up section prevent the generation of security incident.The adjustment amount of slide block is reflected to the high indicator of mould and decoder through screw thread transmission, worm and gear group, gear-box and a series of gearratios of gear pair, and then is shown on the control screen.The operator can adjust accurately by the numerical value of control screen display, adjusts precision and reaches 0.1mm.This kind is simple in structure, easily make and assembling, and the precision height is easy to operate.
As improvement, it also comprises be used to the rotation speed monitoring device of monitoring described four worm screw rotational synchronization, and described rotation speed monitoring device is installed in four worm screws on the output shaft any one.The rotating speed uniformity of connecting axle before and after can further monitoring (two groups of worm screws namely).
