Technical Field
The utility model relates to a press technical field, in particular to hot die forging press seals high adjusting device.
Background
A closing height adjusting apparatus of a hot die forging press in the related art, as shown in fig. 1, realizes the closing height adjustment by changing the length a of a link. When the sealing height needs to be adjusted, the oil cylinder controls the pressing rod 6 to lock the eccentric shaft 1, so that a certain gap is formed between the pressing rod and the eccentric shaft 1, and the condition required by adjusting the sealing height is achieved; the eccentric shaft neck of the eccentric shaft is connected with the lower end of the connecting rod, the eccentric shaft 1 is further provided with a turbine, a worm 8 meshed with the turbine is arranged in the sliding block, the support of the worm is installed in the sliding block, one end of the worm is in transmission connection with a universal coupling 5 through a gear pair 7, and the universal coupling is in driving connection with a motor 4 installed on the guide rail. When the motor 4 drives the eccentric shaft to rotate through the universal coupling 5, the bevel gear pair 7 and the worm 8, the eccentric phase of the eccentric shaft 1 is changed, so that the length A of the connecting rod can be adjusted, and finally the sealing height of the press machine can be adjusted. However, since the motor 4 is fixed on the guide rail, the spline shaft and the spline housing of the universal joint coupler must move up and down along with the motor, and the universal joint mainly comprises the spline shaft, the spline housing and the fork head. When the spline shaft main part is in the spline housing, the universal joint can normally work to bear larger torque, otherwise the universal joint spline arm shaft is easy to break. When the arm shaft is fully inserted into the arm sleeve, the slide block is at the top dead center position, so that the slide block must be at the top dead center position when the seal height is adjusted. When the closing height is adjusted, the universal joint bears larger torque when rotating, but in actual working conditions, the spline shaft of the universal joint does reciprocating motion along with the press machine, so that the spline shaft and the spline sleeve are required to have higher coaxiality and good lubricating conditions, but the working environment of the press machine is poorer, and the spline arm shaft of the universal joint is often broken in the process of adjusting the closing height. Especially when the press slider is overloaded before running to the lower dead point, the clutch can skid and the occurrence of stuffy car, if the problem is solved by adjusting the closed main height, the transmission torque of the universal joint needs to be added, and the breakage of the arm shaft is more easily caused.
SUMMERY OF THE UTILITY MODEL
