Referring to fig. 1-4, the present embodiment provides a lifting balancing device for insert of drawing die, comprising a lifting plate 1, a chute 10 provided on the upper surface of the lifting plate 1, a pair of sliding blocks 11 slidably connected to the side walls of the chute 10, a round hole 110 provided on the rear surface of the sliding blocks 11, a lifting ring 12 fixedly connected to the upper surface of the sliding blocks 11, an adjusting groove 13 provided on the rear surface of the lifting plate 1, a pair of adjusting blocks 14 slidably connected to the side walls of the adjusting groove 13, a threaded groove 140 provided on the rear surface of the adjusting block 14, a half-tooth screw 141 screwed to the threaded groove 140, a connecting block 2 provided on the lower side of the lifting plate 1, and an insert 3 provided on the lower side of the connecting block 2.

The working principle is as follows: firstly, loosening the half-tooth screw 141, sliding the two adjusting blocks 14 to a proper distance, screwing the half-tooth screw 141 after the two sides reach lever balance, fixing the sliding block 11 through the friction force between the hexagonal head of the rear end of the half-tooth screw 141 and the lifting plate 1, and then lifting the lifting plate 1 by using lifting equipment.

In order to enable a worker to better judge whether the horizontal state is adjusted, the upper surface of the lifting plate 1 is fixedly connected with the horizontal plate 15, the upper surface of the horizontal plate 15 is provided with the horizontal groove 150, the side wall of the horizontal groove 150 is slidably connected with the horizontal block 151, and the friction force between the horizontal block 151 and the horizontal groove 150 is small, so that the horizontal block 151 slides only when a certain inclination exists, and when the horizontal block 151 is adjusted to be not in the two ends of the horizontal groove 150 but not in the two ends of the horizontal groove, the horizontal state is adjusted at the moment, and the lifting can be realized only by screwing the half-tooth screw 141.

Considering that the operator knows the mass of the insert 3 or the lifting center of gravity, the upper surface of the rear side of the slider 11 is provided with the mark 111, the upper surface of the rear side of the lifting plate 1 is provided with the scale mark 112, and the operator can quickly adjust the weight to be balanced by directly adjusting the scale mark 112 and the mark 111 after obtaining the moment arm by roughly calculating f1.11=f2.12.

If the specifications of the insert 3 are more, when the staff does not know the mass of the insert 3, the weighing sensor 16 is installed on the lower surface of the lifting plate 1, the upper surface of the connecting block 2 is fixedly connected with the weighing sensor 16, and then the indication number of the weighing sensor 16 can be read and then adjusted.

In order to ensure that the insert 3 can be stably and not fall down after being lifted during operation, a threaded fixing hole 20 is formed in the connecting block 2, the threaded fixing hole 20 is in threaded connection with a fastening screw 21, and the lower end of the threaded fixing hole 20 extends into the insert 3, so that the insert 3 is ensured to be relatively stable after being lifted.

In addition, in order to facilitate the tightness of the screws, the diameter of the half-thread screw 141 is equal to that of the round hole 110, and the rear end of the half-thread screw 141 and the upper end of the fastening screw 21 are fixedly connected with the L-shaped wrench 17, so that the tightness of the screws is more convenient.

Finally, the upper half part of the lifting ring 12 is in an inverted V shape, the connecting block 2 is in an L shape, and the inverted V shape of the upper half part of the lifting ring 12 can reduce the sliding of the lifting hook when the lifting hook is hooked on the lifting ring 12, so that the device is more stable after being lifted.

When the drawing die insert lifting balance device in the embodiment is specifically used, firstly, the insert 3 is connected with the connecting block 2 through the fastening screw 21, the lifting hook of the lifting device is hooked on the two lifting rings 12, the sliding of the lifting hook when the lifting hook is hooked on the lifting rings 12 can be reduced through the inverted V shape of the upper half part of the lifting rings 12, if a worker knows the mass and the lifting gravity center of the insert 3, the half-tooth screw 141 is directly unscrewed through the L-shaped spanner, the two adjusting blocks 14 slide to a proper distance, after the two sides reach lever balance, the half-tooth screw 141 is unscrewed again, the sliding block 11 is fixed through the friction force between the rear end hexagon head of the half-tooth screw 141 and the lifting plate 1, at this time, the lifting plate 1 is lifted by the lifting device, because the two sides reach lever balance, the insert 3 can always keep horizontal during lifting and transferring, if the worker does not know the mass and the gravity center of the insert 3, the position of the adjusting block 14 can be readjusted after observing the number on the weighing sensor 16, the lever balance is reached, the screw 141 can be unscrewed through the mutual adjustment of the two adjusting blocks, and the thread line is not exactly reached when the thread is in a state of being close to the thread 110, and the thread is not screwed to the thread line 110, and the thread is not screwed down at one end of the thread 110, the thread is tightly adjusted, and the thread is not screwed to the thread has the thread is tightly adjusted, and the thread is tightly adjacent to the thread hole, and has the thread is in the thread is tightly screwed to the thread has a hole and has a hole.
