Abstract
The invention discloses a hydraulic press buffering system. One or more main hydraulic cylinders are arranged on a machine body; a piston rod of each main hydraulic cylinder is connected and fixed together with a slide block; one or more buffering hydraulic cylinders are arranged on the machine body; a piston rod of each buffering hydraulic cylinder is connected and fixed together with the slide block; the piston cavity of each controlling hydraulic cylinder is communicated with the piston cavity of each buffering hydraulic cylinder through a pipeline; the piston cavity of each controlling hydraulic cylinder is connected with an oil tank through an electromagnetic valve; a piston of each controlling hydraulic cylinder is connected and fixed together with a threaded sleeve; a screw rod is arranged in an internal thread of the threaded sleeve; and the screw rod is connected and fixed together with a servo motor shaft. The hydraulic press buffering system has the advantage of high automatic degree, the buffering force and buffering time can be set according to practical requirements of a process, the product quality can be well improved, and normal running of equipment is facilitated.
Description
Technical field
The present invention relates to hydraulic press, be specifically related to the hydraulic press buffer system, belong to the hydraulic press technical field.
Background technology
Hydraulic press is at stamping-out, can produce larger moment impact in shearing and other technical process, for this reason, the hydraulic press relatively large or accurate for some generally all arranges buffer unit, existing buffer unit generally is arranged on the spring in the ram travel path, block rubber, cylinder or hydraulic cylinder, the principle of its utilization is the purpose that reaction force that medium produces through overcompression reaches buffering, although the sort buffer device has advantage simple in structure, but, because cushion effect is uncontrollable, so, can't make corresponding adjustment according to the concrete condition of technique, sometimes even this cushion effect that produces even play opposite effect.
Summary of the invention
The object of the invention is to: for the existing defects of buffer system of existing hydraulic press, the invention provides a kind of novel hydraulic press buffer system, overcome the existing existing defects of hydraulic press buffer system, the present invention realizes that the technical scheme that above-mentioned purpose adopts is: described hydraulic press buffer system, it comprises: servomotor, leading screw, silk braid, the control hydraulic cylinder, magnetic valve, fuel tank, main hydraulic cylinder, buffering hydraulic cylinder, fuselage, slide block, form, it is characterized in that: at fuselage one or more main hydraulic cylinder is installed, piston rod and the slide block of described main hydraulic cylinder are connected and fixed, install and fix one or more buffering hydraulic cylinder at fuselage, piston rod and the slide block of described buffering hydraulic cylinder are connected and fixed, the plunger shaft of described control hydraulic cylinder communicates with the plunger shaft of buffering hydraulic cylinder by pipeline, the plunger shaft of control hydraulic cylinder links to each other with fuel tank through magnetic valve, piston and the silk braid of control hydraulic cylinder are connected and fixed, be provided with screw mandrel in the internal thread of silk braid, described screw mandrel and servo motor shaft are connected and fixed.
Operation principle of the present invention is: main hydraulic cylinder is in the descending process of pressurization, technical process be about to complete in, that is: in the time of need to entering buffer status, signal source and programme-control closed electromagnetic valve, servomotor work, and driven plunger compression hydraulic oil, thereby making the interior pressure rise of buffering hydraulic cylinder, this pressure drag limited slip block is descending, thereby play the effect of buffering, when slide block went back to the city, controlled lower in signal source and program, cushion effect was removed.
Beneficial effect: have structure principle chart of the present invention and operation principle to find out, the present invention has the higher advantage of automaticity, especially can cushion effect and buffer time be set according to the actual needs of technique, can improve the quality of products preferably, and be conducive to the normal operation of equipment.
