Abstract
The invention relates to a compound drive mechanical servo press, which comprises a frame, a crank, a connecting rod, a servomotor, a ball screw, a slide block in a slide rail, a three-pair component, a punch hammer connecting rod and a punch hammer, wherein the crank is connected with the frame through a revolving pair; the crank is connected with a high-power constant-speed motor; the servomotor is connected with the slide block through the ball screw; three nodes of the three-pair component are respectively connected with the connecting rod, the punch hammer connecting rod and the slide block in the slide rail; the connecting rod is connected with the crank through a revolving pair; the tail of the punch hammer connecting rod is connected with the punch hammer through a revolving pair; and the punch hammer is positioned in a fixed guide rail. By matching the common high-power constant-speed motor and the low-power servomotor, the punching speed and punching position of the punch hammer can be accurately controlled, the problem of overhigh manufacturing cost of a high-power mechanical servo press is solved, the arranged three-pair component can diversify a pressure working curve of the punch hammer, and the compound drive mechanical servo press meets requirements of various punching operations.
Description
Technical field
The present invention relates to not have the metal forming process equipment of cutting, specifically, relate to a kind of servo-pressing machine.
Background technology
At the metal forming manufacture field, hydraulic press machine and mechanical press are two kinds of main equipments.Hydraulic press machine production efficiency is low, hydraulic system maintenance is difficult and cost is high.Traditional mechanical press lacks " flexibility ", can not obtain the pressure working curve of user according to different processing technology needs, is difficult to satisfy the modern market product diversification, changes requirement fast, that batch is little.In recent years, the mechanical press that servomotor directly drives has appearred, as the wild company of day Home Network link lever press, Japan Xiao Song HF series forcing press, Ohio, USA university duplex bar forcing press, Qiqihar second lathe group forcing press, this press structure form and standard machinery forcing press are basic identical, only change common electric machine into servomotor, can improve the speed characteristics and the dynamic performance of slide block by the input of regulating servomotor, this forcing press is not owing to use flywheel, energy is all provided by servomotor during punching press, if when needing large tonnage pressing machine, then need to use powerful servomotor, but high-power servomotor price is very expensive, and therefore the manufacturing cost of this forcing press is very high.
Summary of the invention
The objective of the invention is at existing metal forming is low, difficult in maintenance with the production efficiency that forcing press exists, cost is high and above-mentioned deficiency such as " flexibility " difference, the invention provides a kind of compound driving device formula servo-pressing machine, this forcing press is decided the rotating speed motor and the small-power servomotor drives jointly by high-power, high-power constant-seed motor provides the punching press work done, the small-power servomotor is realized the adjustment of block stamp position and speed, this forcing press can be according to different pressure processing crafts, complicated motion output rule is provided, satisfies the requirement of various stamping press.
Technical scheme of the present invention is: a kind of compound driving device formula servo-pressing machine, described forcing press comprises frame, crank, connecting rod, servomotor, ball-screw, the slide block in slide rail, three submembers, block stamp connecting rod and block stamp, and crank is connected by revolute pair with frame; Crank is decided the rotating speed motor and is connected with high-power, and high-powerly decides the rotation of rotating speed driven by motor crank by this; Be connected by ball-screw between small-power servomotor and the slide block, the rotation of servomotor drives ball-screw and rotates, and then the slide block that is connected on the ball-screw nut is moved; Three nodes of three submembers are connected with connecting rod, block stamp connecting rod, slide block in slide rail respectively, and connecting rod is connected by revolute pair with crank, and the end of block stamp connecting rod is connected with block stamp by revolute pair, and block stamp is within the fixed guide.
Beneficial effect of the present invention is: the present invention utilizes high-power constant speed common electric machine and small-power servomotor, can control the drawing velocity and the stamping position of block stamp accurately, solve the too high difficult problem of high-power machinery formula servo-pressing machine manufacturing cost, and the adding of three submembers, can make the pressure working curve of block stamp more diversified, finish stamping-out, blanking, bending, moulding, draw and technologies such as pressure-sizing.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
Specific embodiments of the invention as shown in Figure 1, a kind of compound driving device formula servo-pressing machine, described forcing press comprises frame 1, crank 2, connecting rod 3, servomotor 4, ball-screw 5, the slide block in slide rail 6, three submembers 7, block stamp connecting rod 8 and block stamp 9, and crank 2 and frame 1 are connected by revolute pair; Crank 2 is decided the rotating speed motor and is connected with high-power, and high-powerly decides 2 rotations of rotating speed driven by motor crank by this; Be connected by ball-screw 5 between small-power servomotor 4 and the slide block 6, the rotation of servomotor 4 drives ball-screw 5 and rotates, and then the slide block 6 that is connected on ball-screw 5 nuts is moved; Three nodes of three submembers 7 are connected with connecting rod 3, block stamp connecting rod 8, slide block 6 in slide rail respectively, and connecting rod 3 and crank 2 are connected by revolute pair, and the end of block stamp connecting rod 8 is connected with block stamp 9 by revolute pair, and block stamp 9 is within the fixed guide.
During work, crank 2 rotates under the high-power drive of deciding the rotating speed motor, for forcing press provides main kinetic energy, utilize ball screw assembly, 5 that rotatablely moving of servomotor 4 is converted to rectilinear motion, thereby driving slide block 6 beginnings moves in slide rail, realize the adjustment of block stamp 9 positions and speed, under crank 2 and slide block 6 associated movement effects, connecting rod 3 and three submembers 7 are according to complex track setting in motion comparatively, in this process, block stamp 9 also setting in motion under the effect of block stamp connecting rod 8 is because it is spacing to be subjected to the horizontal direction of guide rail, and block stamp connecting rod 8 is hinged again with block stamp 9, so block stamp 9 can only punching press up and down in guide rail.
