A kind of electric screw press that the utility model provides, comprise motor, fuselage, slide block, screw rod and nut, it is characterized by: slide block can do reciprocating linear motion along the guide rail of fuselage, nut and fuselage are connected as one, the threaded engagement of screw rod and nut, and thrust bearing is equipped with in the bottom of screw rod, and cooperate with slide block by bearing, upper end at screw rod is equipped with flywheel, and pinion is meshed with gear wheel on the flywheel, the rotation of motor drives pinion; Brake is installed in the top of slide block, and brake block upwards compresses gear wheel by the spring force effect, prevents its rotation; The rectilinear motion measuring instrument is installed on the fuselage, in order to detect the displacement of slide block.
It is for the helical movement that motor of the present utility model drives gear wheel (flywheel) by pinion, the screw of flywheel and screw rod is converted to the rectilinear motion of slide block by screw pair.The torque of motor and rotating speed can be controlled the kinetic energy of gear wheel (flywheel) and the speed of slide block.Have the advantage of number of strokes height and blow energy and speed-controllable, be applicable to multiple pressure processing craft.Particularly, the utlity model has following advantage:
1. adopt motor to drive the gear wheel rotation, rotatablely moving of motor is converted to the rectilinear motion of slide block by screw pair through pinion.
2. according to the structure needs, the fly press of different size can select for use one or more motor to drive the gear wheel rotation by pinion.
3. according to the structure needs, the fly press of different size, can select gear wheel respectively is that high gear or pinion are high gear.
4. the control parameter that changes motor can be controlled the kinetic energy of flywheel, the motion of slide block (direction, speed, backward position), is applicable to multiple pressure processing craft.
5. adopt overload-release clutch to be subjected to excessive torque to prevent motor rotor and pinion, can also adopt composite to make pinion, the impulsive force with in reducing to turn round makes stable drive.
Description of drawings
Fig. 1 is the structure principle chart of electric screw press, (version when the facing of forcing press, partial sectional view, gear wheel are high gear).
Fig. 2 is the structure principle chart of electric screw press, (version when the facing of forcing press, partial sectional view, pinion are high gear).
Fig. 3 is the structure principle chart of electric screw press, (vertical view of forcing press).
The specific embodiment
The utility model is further specified as follows with example in conjunction with the accompanying drawings:
As shown in the figure, four guide rails are arranged on the fuselage 1 of forcing press, slide block 2 can do reciprocating linear motion along the fuselage guide rail.Nut 8 is connected as one with fuselage 1 by flange 6 and key 7, the threaded engagement of screw rod 5 and nut 8.Thrust bearing 3 is equipped with in the bottom of screw rod 5, and cooperates with slide block 2 by bearing 4.Be combined into flywheel by disk 9, gear wheel 10, brake pad 11, wheel hub 12, bolt 13 and spring 14, flywheel is installed in the upper end of screw rod 5.Pinion 16 is installed in the motor cabinet 18 by bearing 15 parts such as grade, and is meshed with gear wheel 10.Pinion 17 adopts the composite manufacturing, and the impulsive force in can reducing to turn round makes stable drive.Motor 19 drives pinion 16 rotations by overload-release clutch 17, and overload-release clutch 17 can prevent that motor rotor and pinion 16 are subjected to excessive torque.Motor 19 and motor cabinet 18 are for fixedlying connected and being installed on the fuselage 1 by bolt 20.Brake is made up of brake block 21, spring 22, brake cylinder body 23 etc., is installed in the top of slide block 2, and brake block 21 upwards compresses gear wheel 10 by the power effect of spring 22, prevents its rotation.As want release brake, then can with compression spring 22, allow brake block 21 break away from gear wheel 10 to brake cylinder body 23 stuffing pressure fluids.Rectilinear motion measuring instrument 23 is installed in the front of fuselage 1, in order to detect the displacement of slide block.
The utility model can adopt gear wheel 10 or pinion 16 as high gear.
Operation principle of the present utility model is as follows: release brake, operation control system can make motor 19 turning on request, rotating speed and torque rotation, and it is for the helical movement to drive gear wheels 10 by pinion 16.When motor 19 was rotated in the forward, the screw thread by nut 8 was transformed to slide block 2 moving downward along the fuselage guide rail to the screw of screw rod 5.The rotating speed of gear wheel 10 (flywheel) is ascending, and kinetic energy is also ascending.The size of kinetic energy depends on the driving procedure parameter of motor 19, is detected by rectilinear motion measuring instrument 23.When slide block 2 went downwards to mould compacting workpiece, resistance increased, and flywheel slows down and also discharges kinetic energy, became the downward pressure of slide block 2 by screw rod 5, nut 8 and fuselage 1, made component shaping.When motor 19 reverse rotations, flywheel and screw rod 5 are done the reverse acting spiral motion, so slide block 2 moves upward (backhaul) along the fuselage guide rail, the acceleration of slide block 2 backhauls and moderating process depend on the control parameter of motor 19.When closing on the backhaul predeterminated position, send signal by rectilinear motion measuring instrument 23, motor 19 quits work, brake, so gear wheel 10 stops operating, slide block 2 stops at the backhaul predeterminated position.
