Description
Technical field
The utility model relates to a kind of hydraulic pressure modeling machine structure control system of metal cold spinning end socket flanger, and particularly a kind of three oil cylinders, four connecting rods of cold spinning end socket flanger are imitated the type control device.
Background technology
The eighties in last century, China introduces and imitated cold spinning end socket flanger has two kinds of structures, that is: " T " font structure of gondola " one " font structure and Germany.Because of the structure of two kinds of flangers respectively has pluses and minuses, so China makes up the hydraulic pressure modeling machine structure of " returning " glyph framework, transmission mechanism and the German flanger of Italian flanger and transform; Simultaneously, electric part has also been done corresponding adjustment, and the conventional element of interlocking such as original contactor and button or interlocking has been transformed into the control of PLC system, and this also is the at present domestic cold spinning end socket flanger that generally adopts.The cold spinning end socket flanger electrical system of China is made up of substrate, power module, CPU module, digital quantity input module, digital quantity output module, switch, relay, electromagnetic valve coil and executive component etc., because of control section all is the digital quantity interface, so, when the modeling machine structure moves, will all open spool because of the electromagnetic valve coil of energising, system's hydraulic oil is just from flowing through here, after the dead electricity, spool is under the effect of spring force, will Close All, system's hydraulic oil is just from ending here.So the flow fuel feeding that tiltedly draws oil cylinder, synchronous fuel tank group to configure according to flow control valve in the modeling machine structure that is to say that tiltedly drawing oil cylinder and synchronous fuel tank group is the constant speed operation.Wherein the synchronous fuel tank group is to be made of two diameter differences, oil cylinder that length is identical, oil cylinder and back oil cylinder before being divided into; The preceding oil pocket annulus area of back oil cylinder equates with the back oil pocket area of preceding oil cylinder, preceding oil cylinder and back oil cylinder are the mode of being connected in series, thereby oil cylinder and back oil cylinder are under flexible measure-alike situation before the assurance, the hydraulic oil constancy of volume that preceding oil pocket between the maintenance two-piston and back oil pocket are discharged, supplied with; The parallel distance of preceding oil cylinder and back oil cylinder is determined by pressure wheel main shaft link position, therefore, two identical and parallel oil cylinders of length are connected with flanger frame fixation end with the pressure wheel main shaft by rotary pin shaft respectively, just having constituted one is the parallelogram linkage of centre point with the rotary pin shaft, and the motion mode that remains with parallelogram provides up and down the power that pushes away, draws to the pressure wheel main shaft; Tiltedly draw the imitative molded dimension of oil cylinder control to use, the length of oil cylinder must equate with the axis section radius of briquetting roller mould, and be parallel to each other, the spacing of parallel lines is determined by the pressure wheel main axis length, like this, tiltedly draw the oil cylinder two ends to constitute two centre points with framework, pressure wheel main shaft respectively with rotary pin shaft, the pressure point of pressure wheel main shaft and briquetting roller constitutes a centre point, the axis section radius of briquetting roller mould constitutes virtual centre point, like this, two fixing points, pressure point and virtual point have just constituted the parallelogram linkage of the imitative type of motion.Though the flanger after improving has incorporated the advantage of the two, because hydraulic pressure modeling machine structure still adopts the control technology of the traditional Electromagnetic Control direction valve of Germany, flow valve, pressure valve, so still there is following shortcoming in this hydraulic pressure modeling machine structure:
1, is difficult to control crudy.Flanger is when converted products, can not adjust oil cylinder because of the three position four-way electromagnetic valve of the routine that adopts and import and export flow, cause the flexible speed of oil cylinder not adjust, for solving the end socket process quality issue, the minimum speed of the end socket kind of often processing can only be set at the work feed speed of oil cylinder, therefore, production efficiency is lower, versatility is relatively poor.
2, be not suitable for the Development and Trial of new product.When the minimum oil cylinder setting speed of flanger processing end socket kind can not satisfy titanium alloy, almag, nickel alloy, two-way steel, composite plate rotary pressed head crudy, will adjust the flow control valve of Hydraulic Station, to change the work speed of synchronous fuel tank; Therefore, not only time-consuming, but also trouble is not suitable for Development and Trial and the single-piece or the small lot batch manufacture of new product.
3, increase product and processed preceding auxiliary time.Flanger is when head formed by spinning, because of the command range of synchronous fuel tank is to stretch out or withdraw with the speed after setting, and tiltedly draw oil cylinder under the promotion or pulling of synchronous fuel tank, what move is the hinge track of parallelogram, constitute curve by the hinge tracing point, because the existence of curve the phenomenon that pitch does not wait will occur, and then influence the die cavity quality of product and the uniformity of material density; For satisfying the die cavity quality requirement of product, usually all will choose product wants the mid point of segment height arc length of spinning as reference, and calculate the segment girth and rotate a circle the needed time, the measuring and calculating synchronous fuel tank stretches out or the speed of withdrawing is adjusted the flow control valve of Hydraulic Station; So, increased the auxiliary time before the product processing, cause initial workpiece product process-cycle long, day balanced produce wayward.
Summary of the invention
In order to solve the shortcoming and defect that exists in the above-mentioned prior art, the purpose of this utility model is to design a kind of three oil cylinders, four connecting rod modeling machine structures of cold spinning end socket flanger, can realize that three oil cylinders, four connecting rods are under the control of magnetic railings ruler and angle rotary encoder feedback fraction, the import and export flow of online adjustment oil cylinder, control oil cylinder stretching speed, make the single-piece end socket or the small lot end socket of unlike material in spinning process, have more versatility, not only can enhance productivity, can solve the technical problem of continuous multi-curvature head formed by spinning again well, satisfy the process requirements that the smart skill of equipment is produced.The technical solution of the utility model is as follows:
A kind of three oil cylinders, four connecting rods of cold spinning end socket flanger are imitated the type control device, it is characterized in that comprising: power module, CPU module, RS232 communication module, digital quantity input module, digital quantity output module, high speed counting module, D/A output module, touch-screen, magnetic railings ruler, rotary encoder and proportioning valve amplifier;
