Abstract

The invention discloses a mechanical fast-forward hydraulic press machine. The mechanical fast-forward hydraulic press machine is formed by a servo motor, a ball screw assembly, a connecting rod mechanism, a hydraulic oil cylinder and a sliding block, and is characterized in that the ball screw assembly is driven to do linear motion due to the rotation of the servo motor, the connecting rod mechanism, the hydraulic oil cylinder and the sliding block are driven to do slider-crank mechanism motion by the ball screw assembly, the servo motor stops rapidly when the connecting rod mechanism is unbent, and the fast motion is finished; and the hydraulic oil cylinder is driven to do working feed by a hydraulic system so as to finish the technologies such as blanking, stretching and pressing, the hydraulic oil cylinder returns to the primary position after the technologies are finished, and then, the servo motor can drive the connecting rod mechanism to rapidly return to an original state through the ball screw assembly. According to the mechanical fast-forward hydraulic press machine disclosed by the invention, the transmission is realized by adopting the servo motor and a ball screw, the fast-forward speed is far higher than that of hydraulic transmission, and the mechanical fast-forward hydraulic press machine disclosed by the invention has the advantages that the speed is fast, the pressurization is stable, the noise is low, the energy is saved, and the like.

Description

A kind of mechanical F.F. hydraulic press
Technical field
The invention belongs to mechanical forging technology field, be specifically related to a kind ofly be used for that sheet metal blanking, bending, flange, thin plate stretch, smartly dash, metal parts cold-stamped forging equipment.
Background technology
Hydraulic press mainly is that organic frame, hydraulic system, cooling system, pressurization oil cylinder, patrix and counterdie are formed, and the pressurization oil cylinder is contained in the frame upper end, and connects with patrix, and cooling system connects with upper die and lower die.The mobile oil cylinder that the frame lower end is equipped with travelling table and is connected with travelling table, counterdie is placed on the mobile working table top; Its operation principle is: the driven by motor oil pump rotates; Pump is the oil suction fuel feeding from fuel tank, with mechanical energy be converted into Hydraulic Station pressure can, hydraulic oil is through the combination of various valves; Realized direction, pressure, Flow-rate adjustment; Be back in the oil cylinder or oil motor of hydraulic machinery through external pipeline, thereby conversion, the size of strength and the speed of speed of control hydraulic motor direction are accomplished the processing to workpiece; The weak point of hydraulic press: (1) during with the direct transmission of pump, installation power is bigger than corresponding punching machine; (2) owing to boost and step-down all needs certain hour in the working cylinder, the switching-over of valve also needs certain hour, and idle running speed is not high enough; (3) because liquid has compressibility, when fast discharging, can cause the vibration of press body or hydraulic system, punching precision is not high.
Summary of the invention
The present invention is directed to the deficiency of prior art, the mechanical F.F. hydraulic press that a kind of speed is fast, pressurization is steady, noise is low is provided, be used for the forging and pressing processing of sheet metal.
The technical scheme that the technical problem that the present invention will solve is taked is: described tool F.F. hydraulic press is made up of servomotor, ball screw assembly,, linkage, hydraulic jack, slide block.The servomotor rotation drives the ball screw assembly, moving linearly, and ball screw assembly, promotes linkage, oil cylinder and slide block and does the motion of crank slide block mechanism, and when linkage stretched, servomotor stopped rapidly, and quick acting is accomplished; Hydraulic system promotes oil cylinder and does the work feeding, accomplishes stamping-out, the technologies such as compacting that stretch, and after technology was accomplished, oil cylinder returned; Because of the present invention adopts servomotor and ball-screw transmission, fast forward speed is higher than hydraulic drive far away, and servomotor only does F.F., rewind down effect, and power reduces greatly.Pressure required when stamping-out, stretching, compacting is accomplished by hydraulic system, and the machine pressurization is steady, noise is low, and precision is high.
The invention has the beneficial effects as follows that servomotor has quick operation, brake fast; Highly sensitive advantage can guarantee to have auto-lock function when linkage stretches, and servoly has when a stopping braking function; Thereby guarantee that linkage can bear enough reaction forces; Guarantee hydraulic jack completion stamping-out, during technologies such as the compacting that stretches, and toward swivel motion.The present invention adopts servomotor and ball-screw transmission, and fast forward speed is higher than hydraulic drive far away, and servomotor is only done F.F., rewind down effect, and power reduces greatly; Pressure required when stamping-out, stretching, compacting is accomplished by hydraulic system, and the machine pressurization is steady, noise is low, and precision is high.

The specific embodiment
As can be seen from Figure 1, this tool F.F. hydraulic press is made up of servomotor 1, ball screw assembly, 2, linkage 3, hydraulic jack 4, slide block 5, is characterized in servomotor 1 rotation, drives ball screw assembly, 2 moving linearlies.Ball screw assembly, 2 promotes linkage and oil cylinder and slide block and does the motion of crank slide block mechanism.When linkage stretched, servomotor 1 stopped rapidly.At this moment, quick acting is accomplished, and hydraulic system promotes oil cylinder and does the work feeding, accomplishes technologies such as stamping-out, stretching compacting.
