Abstract
The utility model discloses an adjusting device for adjusting the die height of a die in a press machine, comprising a sliding block and a sliding block adjusting mechanism, wherein the sliding block adjusting mechanism comprises a driving motor and two adjusting shafts symmetrically arranged along the central line of the sliding block; and a speed reducing device is arranged between each adjusting shaft and the driving motor. The adjusting device is characterized in that a friction-type torque limiter is arranged between the output shaft of the driving motor and each speed reducing device; a cam is fixedly and coaxially sleeved on each adjusting shaft; and an approach switch is arranged on one side of each cam. The adjusting device has the advantages that when the sliding block is in contact with an upper die, the sliding block adjusting mechanism is subjected to certain resistance to increase the output torque of the driving motor, now, the friction-type torque limiters slide to enable the driving motor to be separated from the speed reducing devices, and internal gears in the speed reducing devices stop rotating, so that the adjusting shafts and the cams are also led to stop rotating, the approach switches transmit signals to a control system in the sliding block adjusting mechanism after detecting that the cams stop rotating, and the control system controls the driving motor to stop operating, so as to prevent the driving motor from being damaged due to overload, meanwhile the sliding block is also prevented from continuously moving downwards to damage the die.
Description
Technical field
The utility model relates to a kind of forcing press, relates in particular to the high adjusting device of mould mould in a kind of forcing press.
Background technology
At present in the forcing press to the high adjustment of mould mould normally through slide block and drive that the upper and lower mobile guiding mechanism of slide block realizes.During work, guiding mechanism drive slide block moves down until the slide block bottom surface and contacts with the mold end face; But in the process of slide block adjustment downwards; When slide block touches mold; Guiding mechanism can run into certain resistance, moves down (being that motor works on) if guiding mechanism continuation this moment drives slide block, then can cause the output load of motor to strengthen; Finally cause the electric motor overheating scaling loss, and slide block touch that the mold continued moves down also can mold damage.
Summary of the invention
The utility model technical problem to be solved provides a kind of in the process that slide block moves, and can prevent that motor from can prevent simultaneously the high adjusting device of mould mould in the forcing press of mold damage because of the overload scaling loss.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the high adjusting device of mould mould in a kind of forcing press; Comprise slide block and slide block guiding mechanism; Described slide block guiding mechanism comprises drive motor and two symmetrically arranged adjustment axles of the center line along slide block; Described drive motor is fixedly mounted on the described slide block, is provided with deceleration device between described adjustment axle and the described drive motor, coaxially on the described adjustment axle is set with worm screw; Described slide block is provided with Worm and worm-wheel gearing; Be provided with the friction-type torque limiter between the output shaft of described drive motor and the described deceleration device, coaxial fixed cover is connected to cam on the described adjustment axle, and a side of described cam is provided with near switch.
Described deceleration device comprises reduction box and the driving gear, one-level travelling gear and the secondary travelling gear that are arranged in the described reduction box; Described reduction box is fixedly mounted on the described slide block; Described driving gear and one-level driving gearshaft are connected in the described reduction box; Connect through described friction-type torque limiter between the wheel shaft of described driving gear and the output shaft of described drive motor; Described driving gear, one-level travelling gear, secondary travelling gear are meshed successively; Described adjustment axle passes described reduction box and is coupling with described reduction box through the bearing supporting, and described secondary travelling gear is coaxial fixedly sleeved on described adjustment axle.
On the described tank wall that is fixedly mounted on described reduction box near switch, described near switch near described cam.
Described Worm and worm-wheel gearing comprises worm gear case, worm gear, set screw and adjusting nut; Described worm gear case is fixedly installed on the described slide block; The end of described set screw is stretched in the described worm gear case and is coupling in described worm gear case; The coaxial fixedly sleeved end of described worm gear in described set screw; Described worm gear is meshed with described worm screw, and described adjusting fixed by nut is arranged in the bottom of connecting rod of forcing press, described set screw and described adjusting nut bolt.
Compared with prior art, the utility model has the advantages that owing to be provided with the friction-type torque limiter between the output shaft of drive motor and the deceleration device, and the adjustment axle is gone up a coaxial fixed cover and is connected to cam; One side of cam is provided with near switch, and slide block moves down, when slide block touches mold; The slide block guiding mechanism receives certain resistance increases the output torque of drive motor; At this moment, the friction-type torque limiter just can skid, and makes the disengagement that is connected between drive motor and the deceleration device; The internal gear of deceleration device just stops operating; Cause adjustment axle and cam to stop operating, just signal is passed to the control system in the slide block guiding mechanism and detect near switch after cam stops operating, control system control drive motor quits work; To prevent drive motor, also can prevent to continue to move down mold damage simultaneously because of slide block because of the overload scaling loss.
