Description
Technical field
The utility model relates to a kind of instructional device, specifically a kind of automatic shearing practice-training teaching device.
Background technology
The quick high accuracy automatic shearing equipment is with a wide range of applications; With the steel industry is example; Be that steel rolling mill or steel dispensing unit all is starved of quick high accuracy and cuts into complete equipment automatically; The sheet material of different-thickness different in width need be cut into unified size expeditiously, directly serves household electrical appliances or other production line, and need not reprocessing.Shearing that is to say at the material blank constantly that pauses, when the cutting knife edge of a knife separates, and Length Control system start-up; Feed length is united by PLC, servo-driver and is controlled, trigger beginning after, system is a basic parameter with preset plus-minus speed, top speed and target length directly; Calculate the running speed curve, the feeding of direct drive servovalve motor is when the length of carrying arrives specified length; The coiled material stop motion, the cutting knife edge of a knife downcuts, and coiled material is cut off.Circulate successively, automatically coiled material is cut into the sheet material of specified length.Professional colleges electricity type Major experimental real-training in the past, the controlling object of using each Educational Instrument Factory to produce usually, these controlling object are generally built by section bar, and comparison modelization has certain distance with actual production situation.
Summary of the invention
The purpose of the utility model provides a kind of robotization and shears the practice-training teaching device, this device micro the actual production device, mechanism's intuitive is strong, promptly presses close to produce actual, is convenient to the student again and learns to observe.
The purpose of the utility model realizes through following technical scheme:
A kind of automatic shearing practice-training teaching device, it is characterized in that: this device comprises uncoiling mechanism, straightener roll, drive roll and cutting mechanism, behind uncoiling mechanism, is provided with straightener roll, drive roll and cutting mechanism successively; Cutting mechanism is connected with the frequency converter motor, and drive roll is connected with servomotor; On drive roll, be provided with the clamping cylinder.
The utility model is provided with the shear motor support behind cutting mechanism, the frequency converter motor is arranged on the shear motor support.Said cutting mechanism comprises bracing frame, knife rest and cutting knife, and knife rest is arranged on the bracing frame, and cutting knife is installed on the knife rest, and knife rest is connected with the frequency converter motor.
The utility model is applicable to the THE ADIABATIC SHEAR IN of high precision, the short material of hard, and drive roll is surveyed long servomotor control by Mitsubishi's servo positioning control system control, and clamp system has replaced the hydraulic system on the industrial production line by pneumatic system, and pressure controlling is easy.The travelling speed of shearer is cooperated with shear motor through controller control servomotor by the frequency converter Electric Machine Control efficiently.
Cutter driving is the frequency converter motor, and material transmits and drives is servomotor.Shearing pauses at material and constantly carries out, and cutter mechanism is moved in the speed that whole process middle controller calculates all the time, thereby has guaranteed the speed of shearing.
Cutting mechanism is the pendulum guide rod cutting mechanism, comprises driving link and Passive part, utilizes the rotation of the rotation drive driving link of motor, is converted into the curvilinear motion of driving link pole the rectilinear motion of Passive part pole.Because the rotor axial of motor is fixed, so knife rest also can be done reciprocal motion on a vertical straight line.Utilize the guiding mechanism of two vertical guide rods, guarantee that knife rest can pump on vertical straight line as knife rest.
Shearing that is to say that at the material pause moment blank when cutting knife edge of a knife separated, fixed length was controlled by drive roll; Feed length is controlled by servomotor, after the triggering beginning, is basic parameter with preset plus-minus speed, top speed and target length directly; Calculate the running speed curve, the feeding of direct drive servovalve motor is when the length of carrying arrives specified length; The coiled material stop motion, the cutting knife edge of a knife downcuts, and coiled material is cut off.Circulate successively, automatically coiled material is cut into the sheet material of specified length.The power of stepping up that clamps cylinder just compresses plate by pneumatic transferring to, and makes plate fricton-tight rolling of speed by setting in two rollers, and it is long with survey to accomplish feeding.
The utility model is applicable to high precision, the short material shearing of hard; Can be widely used in the electric automatization of professional colleges, the comprehensive practical traning teaching of electromechanical integration relevant speciality; Small investment, real standard content is comprehensively comprehensive, combines producing the real standard of reality and school effectively; Can let real standard student learn the knowledge of control, Frequency Converter Control, physical construction, mechanical drive and the pneumatic aspect of Programmable Logic Controller application, servomotor; And integrated application in addition, the utility model is simple in structure and unique, has very high use value.
