Description
Technical field
The present invention relates to a kind of structure of NC turret punch machine, be specifically related to a kind of punching structure of NC turret punch machine application switch reluctance servo motor.
Background technology
The punching press main transmission section of traditional NC turret punch machine has mechanical type and two kinds of structures of fluid pressure type.
Mechanical type is that AC asynchronous motor drive flywheel rotates at a high speed, finishes the punching press action by the crank mechanism in conjunction with driving mechanical main transmission of clutch during punching press.After the punching press action is finished, throw-out-of clutch, but AC asynchronous motor does not stop, and is in the state of running up all the time.And the top dead-centre of punching press and bottom dead centre are immutable, are unfavorable for the carrying out of technologies such as the moulding of sheet material or impression.Because the restriction of the startup frequency of clutch, the operating efficiency of whole punch press also is subjected to severely restricts.
The fluid pressure type NC turret punch machine adopts hydraulic system as power source in the power section of punching mechanism.Driving hydraulic cylinder by the hydraulic control card moves back and forth, and form closed-loop control to control card by real-time feedback position of LVDT position-detection sensor and speed, can finish punch press functions such as punching press, moulding, impression and mark, and can point-device control stop position.But the shortcoming of hydraulic system also is very tangible, at first is exactly that power consumption is big, and the Oil pump electrical machinery of Hydraulic Station is in the state of running up always, in view of the characteristics that oil pump itself leaks, keep position accurately, and the running that must not stop is constant to keep-up pressure.Hydraulic system is also very high to the particle requirement of hydraulic oil in addition, requires annual periodic replacement hydraulic oil and work filter core, so user's working service cost is higher.Being exactly the discharging of waste oil in addition, also is the pollution to environment.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, the punching structure of the NC turret punch machine application switch reluctance servo motor of a kind of energy-saving and environmental protection, efficient and freedom from repairs is provided.
Technical scheme of the present invention is: a kind of punching structure of NC turret punch machine application switch reluctance servo motor, comprise switch reluctance servo motor, bent axle, connecting rod and slide block, described switch reluctance servo motor is connected with bent axle, the bent axle that is directly driven by switch reluctance servo motor is connected with connecting rod, connecting rod is connected with slide block again, constitutes a planar linkage mechanism.
Described switch reluctance servo motor can be one, is directly installed on an end of bent axle.
Described switch reluctance servo motor also can be directly installed on the two ends of bent axle respectively for a pair of, and this bent axle is by described switch reluctance servo motor driven in synchronism.
The punching structure of NC turret punch machine application switch reluctance servo motor is that switch reluctance servo motor in the punch-out application specific of NC turret punch machine is as power source, directly be connected with the bent axle one or both ends, motor rotates and directly drives the bent axle rotation, by bent axle swing certain angle or crankshaft rotating, thereby drivening rod mechanism moves up and down, and realizes the punching press energy-conservation, quick and accurate to sheet material.
Described switch reluctance servo motor is a rotor biconvex electrode structure, and rotor is formed by silicon steel plate stacking, and no winding and permanent magnet allow higher temperature rise.
The rotational angle of described bent axle carries encoder feedback by switch reluctance servo motor and carries out half-closed loop control, and the angle or the rotation of bent axle swing can determine according to the distribution in the hole on the processed plate, thereby can carry out high-precision punching press and processing and forming.When adopting pair of switches reluctance servo motor driven in synchronism bent axle, the rotational angle of bent axle carries encoder by the active motor and carries out half-closed loop control, and slave motor is not with encoder, reaches synchronous effect by phase angle, the inside deviation of adjusting principal and subordinate's motor.
The lower dead point position of described slide block can be provided with arbitrarily, can adopt only stroke for the sheet material of different thicknesss of slab, and its punching stroke can be determined according to the thickness of sheet material, moves the needed time thereby reduce idle stroke, can enhance productivity greatly.
The invention has the beneficial effects as follows:
1, specific type of electric machine.Switched reluctance machines is a kind of specific type of electric machine.Starting torque is big, has the soft start characteristic, and starting current is little, avoids electrical network is impacted.Adopt advanced control theory, can realize the accurate control of Position And Velocity, frequently start-stop, forward and reverse running can realize four quadrant running and regenerative braking.Mechanical strength height in addition, system power factor height can reach more than 0.9, and overload capacity is strong.Direct driven loads, rotary inertia is little, the torque ratio of inertias is big, does not need the decelerator transferring power, also control lag can not take place, and is dynamically corresponding fast;
2, energy-conservation.Compare with the mechanical type main transmission of traditional forcing press in the past, saved the clutch of mechanical type main transmission and the transmission device of AC induction motor, simple in structure.Traditional mechanical type main transmission is driven the flywheel rotation and is gathered certain energy by AC induction motor, in the course of work, consumes during the punching press of flywheel energy, and accumulates again when returning top dead-centre.Mechanical clutch is owing to frequent work, and elements such as mechanical friction sheet also need frequent replacing as consumable accessory.And drive main transmission for switched reluctance machines, and energy need not storage, and motor also need not to turn round always, only starts when punching press and institute's energy requirement is provided.Usually be 2500-3000 hour the service life of hydraulic oil, just calculated by eight hours every days, needs to change one time hydraulic oil every year at least.And generally totally the working time reaches hydraulic oil filter core of needs replacing in 1000 hours.Renewal of facing renewal and hydraulic system need the frequent trouble of changing hydraulic oil and screen pack to adopt electric servo main drive gear then to avoid mechanical crankshaft-link rod clutch often to need more;
3, environmental protection.Compare with fluid pressure type main transmission, it had both saved the cooling system of hydraulic oil liquid, did not also have the leakage of hydraulic oil liquid and the pollution of waste oil disposal.When mechanical punch uses pneumatic clutch, can produce great noise.When the slide block diel penetrates plate, can be subjected to the effect of punching press counter-force to produce vibration and impact, the noise that brings thus also can increase with the increase of ram speed and stamping press.Switched reluctance machines but can be the controlling and regulate the speed of slide block of stroke all the time, thereby reach the purpose that reduces noise;
4, efficient.The ram travel and the speed of switch reluctance servo motor drive-type punching mechanism can be adjusted arbitrarily, can select the required shortest route of punching press, farthest save empty stroke time, set proper speed simultaneously, thereby boost productivity effectively;
5, optimize technology.The rotational angle of bent axle carries out half-closed loop control by switched reluctance machines and respective drive unit, and lower dead point position can be provided with arbitrarily, can improve the machining accuracy of mould.According to Sheet Metal Forming Technology and mould-type, control slide block to adapt to various punching press patterns by optimizer, as impression, punching, moulding etc., expanded the processing technology scope that numerical control is dashed.
