Problems solved by technology
[0004] Because the mechanical punching machine adopts the crank linkage mechanism, there is a dead point in the movement, and a flywheel must be assembled, which will cause the punching machine to be bulky, inefficient, and generate large movement noise
The hydraulic power generation medium is pressure oil, which will generate high pressure in the pipeline, coupled with the continuous reciprocating movement of the hydraulic oil, it is easy to cause leakage of hydraulic oil and affect the normal use of the punch press

Abstract
The invention relates to a device for die-cutting metal sheets and provides a metal sheet die-cutting device which can be widely used for die-cutting and molding of metal materials. The metal sheet die-cutting device comprises a servo motor, a speed reducer, a motor belt wheel, a toothed belt, a lead screw belt wheel, a precision nut rotary ball screw, a die mounting base plate, guide posts, guide sleeves, a connecting plate, a middle plate, a stamping die, an upper die plate, an upper limit switch, a return-to-zero switch and a lower limit switch. The precision nut rotary ball screw is formed by a lead screw nut, a combined bearing and a lead screw. The lead screw is arranged in the lead screw nut through threads of the lead screw in an inserted mode. The combined bearing and the lead screw belt wheel are installed on the lead screw nut. A mounting base is arranged below the die mounting base plate. The motor belt wheel is installed above the speed reducer. The lower portion of the speed reducer is connected with the servo motor through a transmission shaft. The speed reducer is fixed to the mounting base through a flange by using bolts. The mounting base is fixed to the die mounting base plate.
Description
technical field [0001] The invention relates to a metal sheet punching device, which relates to a device for punching metal sheets, which can be widely used for punching and forming metal materials. Background technique [0002] As a cold working machine, punch presses are widely used in punching and forming of metal materials, and are common equipment in most manufacturing plants. [0003] The main part of the punch press is its stamping power source. There are two types of power sources widely used now: one is the mechanical type using the crank-link mechanism; the other is the hydraulic transmission type. The mechanical type is driven by the motor to rotate the crankshaft, and the crank drives the connecting rod and the slider to move up and down in a straight line to complete the stamping action; the hydraulic type uses a hydraulic oil pump to generate pressure oil, and controls the movement of the piston rod of the hydraulic cylinder through the oil pipe and solenoid va...
