Abstract
The utility model discloses a die-setting height locking mechanism for a press machine and belongs to the technical field of press machine. The press machine comprises a connecting rod, a bulb screw rod, a pressing sleeve and a sliding block, wherein the upper end of the bulb screw rod is connected to the connecting rod; the lower end of the bulb screw rod is provided with an annular stair; the annular stair is positioned in a slot of the sliding block; the pressing sleeve is in threaded connection with the lower end of the bulb screw rod; a piston and a piston base are sleeved on the bulb screw rod above the pressing sleeve; the piston base is fixed on the sliding block through a bolt; the lower end face of the piston base is provided with an annular slot; the upper end face of the piston base is provided with an oil pouring port; the oil pouring port is communicated with the annular slot; the upper end of the piston is inserted into the annular slot of the piston base; two side walls of the upper end of the piston are respectively provided with a sealing ring; and the lower end face of the piston is fitted with the upper end face of the pressing sleeve. When the die locking is needed, high-pressure oil can be poured from the oil pouring port, the piston can drive the pressing sleeve to move downwards, the bulb screw rod is pressed, the clearance between the bulb screw rod and the connecting rod is eliminated, the bulb screw rod is stopped rotating, and the hydraulic die locking is realized.
Description
Technical field
The utility model relates to a kind of forcing press height of packing compact retaining mechanism, belongs to the press technologies field.
Background technology
Forcing press comprises connecting rod, ball screw, clamping sleeve and slide block, the upper end of ball screw links to each other with connecting rod, the lower end of ball screw is provided with circular step, and circular step is arranged in the groove of described slide block, and clamping sleeve is by being threaded in the lower end of described ball screw.The excircle of clamping sleeve is provided with gear, in order to drive the clamping sleeve rotation, and with the relative position of change clamping sleeve and ball screw, and then the adjusting of realization height of packing compact.After the height of packing compact adjusting puts in place, the screw thread between ball screw and the clamping sleeve need be pinned, stop the ball screw rotation, lock to realize height of packing compact.
The height of packing compact retaining mechanism of tradition forcing press is oil cylinder in the connecting rod bottom, produces power by hydraulic pressure, makes ball screw stressed, eliminates the gap between ball screw and the connecting rod, stops the ball screw rotation, thereby reaches the purpose of hydraulic pressure locked mode.This retaining mechanism, connecting rod need split processing, and its process and assemble difficulty is bigger, can not effectively guarantee the high locking of mould.
The utility model content
The purpose of this utility model is, provides a kind of simple in structure, the forcing press height of packing compact retaining mechanism of reliable lock.
For solving above technical problem, a kind of forcing press height of packing compact retaining mechanism provided by the utility model, comprise connecting rod, ball screw, clamping sleeve and slide block, the upper end of described ball screw links to each other with described connecting rod, the lower end of described ball screw is provided with circular step, described circular step is arranged in the groove of described slide block, described clamping sleeve is by being threaded in the lower end of described ball screw, be set with piston and piston seat on the ball screw of described clamping sleeve top, described piston seat is by being bolted on the described slide block, the lower surface of described piston seat is provided with cannelure, the upper surface of described piston seat is provided with pouring orifice, and described pouring orifice is connected with described cannelure; The upper end of described piston is inserted in the endless groove of described piston seat and the two side of described piston upper end is respectively equipped with sealing ring, and the lower surface of described piston and the upper surface of described clamping sleeve fit.
With respect to prior art, the utility model has been obtained following beneficial effect: regulate when height of packing compact and finish when needing locked mode, in cannelure, inject hydraulic oil by the pouring orifice on the piston seat, hydraulic oil promotes piston and moves down, and piston promotes the downward fine motion of clamping sleeve, makes the thread biting locking between clamping sleeve and the ball screw, and make ball screw stressed, eliminate the gap of ball screw and connecting rod, stop the ball screw rotation, thereby realize the hydraulic pressure locked mode.
