Description
Technical field
The utility model relates to the metal forming process equipment that does not have cutting, specifically, relates to a kind of servo-pressing machine.
Background technology
At the metal forming manufacture field, particularly in sheet-metal press working, moulding, thin plate drawing process, 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 adopts the fixed rotating speed motor as power source usually, by various transmission device, make executing agency carry out work with the fixed pressure curve, can not obtain the pressure working curve of user according to different processing technology needs, the inherent shortcoming that this forcing press lacks " flexibility " has hindered the further raising of Sheet Metal Forming Technology level, thereby is difficult to satisfy the modern market product diversification, changes fast, little requirement in batches.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.
The utility model content
The purpose of this utility model is at existing metal forming low with the production efficiency that forcing press exists, difficult in maintenance, the cost height, and above-mentioned deficiencies such as " flexibility " difference, the utility model provides a kind of two degrees of freedom combination drive mechanical type 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 punching press kinetic energy, 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.
The technical solution of the utility model is: a kind of two degrees of freedom combination drive mechanical type servo-pressing machine, described forcing press comprises frame, first crank, second crank, connecting rod, three submembers, block stamp connecting rod and block stamp, and first crank is connected by revolute pair with frame respectively with second crank; First 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 first crank by this; Second crank is connected with the small-power servomotor, and drives the rotation of second crank by this small-power servomotor; Three nodes of three submembers are connected with connecting rod, block stamp connecting rod, second crank respectively, and connecting rod is connected by revolute pair with first crank, and the end of block stamp connecting rod is connected with block stamp by rotating parafacies, and block stamp is within the fixed guide.
The beneficial effects of the utility model are: the utility model 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, also can make the pressure working curve of block stamp more diversified; Simultaneously, forcing press simple and compact for structure, cost is low, as long as suitable punch die is installed, just can finish stamping-out, blanking, bending, moulding on forcing press, draw and technology such as pressure-sizing.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
Specific embodiment of the utility model as shown in Figure 1, a kind of two degrees of freedom combination drive mechanical type servo-pressing machine, described forcing press comprises that frame 1, first crank 2, second crank 7, connecting rod 3, three submembers 4, block stamp connecting rod 5 and block stamp 6, the first cranks 2 and second crank 7 are connected by revolute pair with frame 1 respectively; First 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 first crank by this; Second crank 7 is connected with the small-power servomotor, and drives 7 rotations of second crank by this small-power servomotor; Three nodes of three submembers 4 are connected with connecting rod 3, block stamp connecting rod 5, second crank 7 respectively, and connecting rod 3 is connected by revolute pair with first crank 2, and the end of block stamp connecting rod 5 is connected with block stamp 6 by revolute pair, and block stamp 6 is within the fixed guide.
During work, first crank 2 rotates under the high-power drive of deciding the rotating speed motor, for forcing press provides main kinetic energy, second crank 7 rotates under the drive of small-power servomotor, realize the control of block stamp 6 positions and speed, under the common effect of rotatablely moving of first crank 2 and second crank 7, connecting rod 3 and three submembers 4 are according to complex track setting in motion comparatively, in this process, block stamp 6 also setting in motion under the effect of block stamp connecting rod 5, because the horizontal direction that is subjected to guide rail is spacing, and block stamp connecting rod 5 is hinged again with block stamp 6, so block stamp 6 can only punching press up and down in guide rail.
