Pressure pin unloading device and method for mold adjustment of hot die forging press

Abstract

The invention relates to the high-end equipment manufacturing industry, in particular to a pressure pin unloading device and method for mold adjustment of a hot die forging press. A locking cylinder and a disc spring are used to lock and release the clamping rod, and a sensor is used to detect the clamping rod. Inject high-pressure gas on the friction surface of the slider to achieve balance and stability and lift the pressure pin upward to reduce the gravity and rotational moment of the pressure pin to achieve the purpose of unloading. Make full use of the PLC controller to realize the rotation of the pressure pin and the locking and loosening Detect the PLC control interlock, solve the problem that the pressure pin rotation torque is too large when the hot die forging adjusts the height of the slider, which causes the rapid wear of the copper sleeve and the damage of the bevel gear pair, worm pair, and coupling splines. The hot-touch forging press and its automatic production line can effectively improve the transmission accuracy, reliability and reliability of the hot-touch forging press and its automatic production line. Productivity.

Description

Technical field: [0001] The invention relates to the technical field of high-end equipment manufacturing industry, in particular to a pressure pin unloading device and method for mold adjustment of a hot forging press. Background technique: [0002] Hot die forging presses and their automated production lines, as representative products of key breakthroughs in the high-end equipment manufacturing industry, are increasingly widely used in China due to their advantages of "precision, high efficiency, green and energy saving". like Figure 8 As shown, it is a structural schematic diagram of the existing hot die forging press. When the height of the slider is adjusted, the motor drives the rolling friction of the eccentric part of the pressure pin through the cross universal coupling, the meshing of the bevel gear pair and the meshing of the worm pair, and then Realize the adjustment of the mold loading height of the slider. After adjustment, the balance piston rod rises upward...

AI Technical Summary

Problems solved by technology

[0003] However, since the pressure pin bears the nominal force, the slider, the upper mold and the connecting rod, the weight is relatively heavy, and the reaction force of the balance bar is superimposed, resulting in a very large static rotational moment of the driving pressure pin, which aggravates the rapid wear of the copper sleeve and the umbrella Damage to gears, worms, and couplings

In addition, because there is no detection and control device on the existing hot die forging press, there may even be a problem of driving under the locked state of the pressure pin, resulting in damage to the transmission connector, and may also cause the motor to burn out due to overload

In addition, in order to ensure the rotation of the pressure pin, a certain gap is reserved in the transmission structure of the pressure pin, which reduces the transmission accuracy of the hot touch forging press.
