Abstract
The invention relates to a numerical control press driven by a linear motor, comprising a press body, wherein the upper part of the press body is provided with a beater mechanism, and the lower part is provided with a mounting die and a worktable for bearing a workpiece; the beater mechanism comprises a main drive gear fixedly arranged at the press body, a beater head seat and a beater head arranged on the beater head seat; the main drive gear is a linear motor; and the beater head seat is directly connected with the linear motor. The numerical control press adopts the linear motor, thereby having the characteristics of high positioning precision, stable servo, sensitive response, a plurality of pressing times, high speed, and the like, and effectively overcoming the defects of back clearance, fraction abrasion, deformation, and the like of the traditional screw-driven system; and the overall precision of the control press is enhanced because four groups of slide rails are arranged for guide. Although the linear motor has higher manufacturing cost at present, on the whole, the invention has the advantages that the mechanic structure is simplified, the number of components easy to be worn is decreased to the least and the precision can be guaranteed in the long term.
Description
Technical field
The present invention relates to a kind of numerical control press mechanical field, particularly a kind of with the numerical control press of linear electric motors as main drive gear.
Background technology
In the numerical control press of prior art,, experienced the change and progress of three phases, be respectively mechanical type, fluid pressure type and servo electric machine type as the main drive gear of punching press power source.
The mechanical type main drive gear is made up of motor, flywheel, clutch and brake, bent axle, connecting rod and slide block etc.Motor rotates by belt and drives the flywheel rotation, and stores certain energy.During punching press, the clutch closure, the flywheel energy is delivered on the drift by crankshaft connecting rod system, when punching press finished, clutch was thrown off when drift moves upward, thereby removed the moment of torsion transmission of flywheel to bent axle, brake begins braking simultaneously, stops when making bent axle turn to top dead-centre.Connecting rod connects bent axle and press ram, rotatablely moving of bent axle is changed into the motion of vertical line up and down of slide block.Slide block moves up and down, and the drift of mould is pressed in the sheet material.The fluid pressure type main drive gear is compared with the mechanical type main drive gear, oil cylinder has replaced frame for movements such as crankshaft-link rod, Hydraulic Station provides power, both are connected by main hydraulic valve block, action by special electronic cards sequencing control whole system, and by the electronic sensor measurement in good time and the feedback that are connected on the oil cylinder piston bar, the final accurate control that realizes drift position, stroke and speed.The version of driven by servomotor formula main drive gear mainly contains following two kinds: a kind of on the basis of traditional mechanical type main transmission, servomotor is directly linked to each other with bent axle, and save flywheel and clutch and brake; Another kind is that servomotor links to each other with crank toggle mechanism by decelerator.Yet existing technology contents all needs to realize the operate as normal of punch press by changing the direction of motion, thereby can increase conversion component, and not only waste material, and course of work easy break-down causes unnecessary loss and trouble.
Summary of the invention
The objective of the invention is to the shortcoming that exists at prior art, provide a kind of simple in structure, precision is high, non-damageable with the numerical control press of linear electric motors as main drive gear.
Technical scheme of the present invention is: a kind of numerical control press driven by linear motor, comprise bed piece, lathe bed top is provided with beater mechanism, the bottom is provided with the workbench of installation mold and carrying workpiece, beater mechanism comprises the main drive gear that is installed in lathe bed, impact headstock and be installed on the impact head that impacts on the headstock, described main drive gear is linear electric motors, impacts headstock and directly is connected with linear electric motors.
Preferably: described lathe bed is provided with guide rail, and described impact headstock is provided with corresponding with it slide rail, impacts headstock and is installed on the guide rail of lathe bed by slide rail.
Preferably: described slide rail is provided with 4 groups, lays respectively at front and the side of impacting headstock.
Features such as beneficial effect of the present invention is: numerical control press of the present invention uses the linear electric motors punching press to have the positioning accuracy height, and is servo steady, and response is sensitive, and the punching press number of times is high, and speed is fast.Adopt linear electric motors as drive system, effectively overcome defectives such as the inevitable existing back clearance of traditional screw type system, frictional dissipation and distortion, and be provided with 4 groups of slide rails and lead, the overall accuracy of equipment is promoted.Though the manufacturing cost of linear electric motors own is higher at present, the frame for movement of comprehensively getting off is simplified, and easy-abrasion part reduces to Min., and precision can be guaranteed for a long time.
