The advantages of the utility model are: 1) After the utility model is moved out, the ordinary adjustment motor can be used, which is not easy to be damaged, and the sealing of the output shaft and the maintenance and replacement are very easy;

2) The utility model adopts a scalable precision universal joint transmission, which solves the problem of elongation and shortening of the transmission shaft when the upper sliding column moves up and down. There is no such problem when adjusting the worm on the upper connecting rod inside the upper bed to move together with the upper sliding column. The assembly and adjustment of the adjustment device are extremely convenient, saving costs and reducing labor intensity;

3) The utility model adds the control and display of the encoder, PLC, and touch screen, which can achieve precise adjustment and control of digital input, making the adjustment of the upper die punch of the super-large powder press more convenient and fast, and providing further intelligent adjustment lay the foundation;

4) The utility model adopts a thrust bearing installed on the end cover of the worm gear, and the lower end surface of the adjusting worm gear acts on the bearing, so that the frictional resistance of adjusting the rotation of the worm gear is very small, and the adjustment resistance is small at a super long distance outside the bed, and the adjustment is more efficient. Easy and convenient. In the past, the lower end surface of the worm wheel was in direct contact with the end cover surface of the worm wheel. Due to the relationship of gravity, the rotational friction resistance was relatively large, and the power requirement for adjusting the motor was relatively large.

Detailed ways

The utility model comprises an upstroke adjustment motor 1, and the upstroke adjustment motor 1 drives the adjustment transmission shaft 5 to rotate through a gear set;

The transmission of the adjustment transmission shaft 5 is divided into two sets, one of which is connected to the telescopic precision universal joint 9, the telescopic precision universal joint 9 drives the rotation of the adjustment worm 11, and the rotation of the adjustment worm 11 drives the rotation of the adjustment worm wheel 13, The adjusting worm gear 13 is connected with the upper connecting rod 12 through a connecting device, and the adjusting worm gear 13 is also threaded with a ball adjustment screw 16, and the ball adjustment screw 16 is connected to the upper sliding column and the upper beam;

The other said adjusting drive shaft drives the rotary encoder 3 to rotate through the encoding shaft coupling 5 .

The upstroke adjustment motor 1 drives the adjustment drive shaft 5 to rotate through the motor adjustment bevel gear 2 .

The adjustment transmission shaft 5 is installed on the adjustment support seat 8 through the tapered roller bearing 5 and the bearing end cover 7 , and the adjustment support seat 8 is fixed on the upper bed 10 .

The adjusting worm gear 13 is installed on the upper connecting rod 12 through a thrust bearing 15 and a worm gear end cover 14 .

The rotary encoder 3 is connected to PLC and displayed on a touch screen.

The working principle of the utility model is: the molding process of the powder product is a process of pressing the powder three times, that is, the pressing of the upper die, the pressing of the lower die and the final pressurization. The adjustment of the first pressurization amount of the upper die punch is realized by adjusting the upper and lower strokes of the upper die punch fixed on the formwork template. The formwork template is fixed on the upper beam of the machine, and the upper beam is connected and The upper die can be adjusted by the adjustment of the ball screw to move up and down, and the movement of the ball screw driven by the transmission of the worm gear pair. At the same time, the calculation and control of the upper punch adjustment motor is carried out through the rotary encoder, PLC and touch screen, so that the upper punch adjustment motor can be controlled to perform automatic adjustment by inputting adjustment data on the touch screen.

The working process of the utility model is: when the utility model is used, the upper punch adjustment motor 1 works and the adjustment transmission shaft 5 is driven by a pair of motor adjustment bevel gears 2 to rotate, and the adjustment transmission shaft 5 is installed through the tapered roller bearing 5 and the bearing end cover 7. On the adjustment support base 8, the adjustment support base 8 is fixed on the upper bed 10. On the one hand, adjust the transmission shaft 5 to drive the rotary encoder 3 to rotate through the encoder coupling 5, and then transmit the data related to the motor rotation to the PLC, and the PLC obtains the data signal and controls the upper punch to adjust the motor 1 according to the requirements of the touch screen operation data. The number of revolutions is finally formed by inputting data on the touch screen for automatic adjustment. On the other hand, the adjustment transmission shaft 5 drives the adjustment worm 11 to rotate through the telescopic precision universal joint 9, and the rotation of the adjustment worm 11 drives the adjustment worm wheel 13 to rotate. The adjusting worm gear 13 is assembled on the upper connecting rod 12 through the thrust bearing 15 and the worm gear end cover 14. The adjusting worm gear 13 and the ball adjusting screw 16 are threaded together. When the worm rotates, the ball adjusting screw 16 is prohibited from rotating.
