Detailed description of the invention
Below in conjunction with accompanying drawing, start stop mode steel plate sample intelligent environment protection shearing equipment of the present invention is described in further detail.A kind of start stop mode steel plate sample intelligent environment protection shearing equipment, comprises and drives running part and shearing equipment body part; Drive running part to comprise motor 1 and reduction box 3, the motor shaft of motor 1 is connected with the high speed input shaft of reduction box 3; Shearing equipment body part comprises frame 13, top in frame 13 is provided with eccentric shaft 5, and one end of eccentric shaft 5 is connected with the low-speed output shaft of reduction box 3, and the bottom in frame 13 is provided with lower slide 24, the top of lower slide 24 is provided with upper tool post 15, and eccentric shaft 5 is connected with upper tool post 15 by connecting rod 6; Flywheel 2 is also provided with, as shown in Figure 1 to Figure 3 between motor 1 and eccentric shaft 5.
In the present embodiment, flywheel 2 is arranged between motor 1 and reduction box 3, and flywheel 2 is fixedly connected with the high speed input shaft of reduction box 3, and as depicted in figs. 1 and 2, or flywheel 2 also can be fixedly connected with the motor shaft of motor 1.Or flywheel 2 also can be arranged between one end of eccentric shaft 5 and reduction box 3, as flywheel 2 also can be fixedly connected with one end of eccentric shaft 5, or flywheel 2 is fixedly connected with the low-speed output shaft of reduction box 3.The weight of flywheel 2 can be 500kg ~ 4000kg.
Concrete, as shown in figures 1 and 3, the start stop mode steel plate sample intelligent environment protection shearing equipment that the present invention proposes, at least comprises two parts, and Part I is for driving running part: it at least comprises motor 1, flywheel 2, reduction box 3; Part II is shearing equipment body, and it at least comprises eccentric shaft 5, connecting rod 6, shearing edge gap adjusting device 7, eccentric shaft positioner 10, pusher tail apparatus 11, cuts front rollgang 12, frame 13, blank length measuring device 19, press-roller device 16.Two parts are connected (one end of eccentric shaft 5 is connected by shaft coupling 4 with the speedy carding process axle of reduction box 3) by shaft coupling 4, can reach convenient and manufacture, the effect of transport and installation and maintenance.
This shearing equipment operation principle is achieved in that being driven across reduction box 3 by motor 1 slows down, then is connected with eccentric shaft 5 by shaft coupling 4; Connecting rod 6 is enclosed within the eccentric part of eccentric shaft 5, and upper tool post 15 is connected with connecting rod 6 by bearing pin 23, and frame 13 in the vertical direction is provided with guide groove, and upper tool post 15 can slide up and down on its guide groove; Eccentric shaft 5 rotational movement upper tool post 15 vertically moves up and down, and lower slide 24 and frame 13 are same weldment, maintain static, thus coordinates upper tool post 15 to realize shear action.For alleviating the weight of complete machine, adopt little motor to realize large shear ability, the present invention is provided with flywheel 2 on the high speed shaft of running part, can realize Great inertia thus apart from shearing.As shown in Figure 3, shearing edge gap adjusting device 7 is arranged on shearing equipment body top board 8, and can realize automatically regulating upper tool post 15 horizontal level, rational blade clearance can realize high-quality shearing; Cut the lower right side that front rollgang 12 is arranged on frame 13, for coordinating the conveying of blank, and vibration when can resist shearing; Pusher tail apparatus 11 is arranged on the right side of frame 13, for being released by the tailing after shearing; Blank length measuring device 19 is arranged on the left side of frame 13, for coordinating the machinery location of the blank shearing different length.Compared with prior art, functional configuration is complete in the present invention, and automaticity is higher.
The original operating state (i.e. odd-job position) of this start stop mode steel plate sample intelligent environment protection shearing equipment is positioned at peak for the eccentric part of eccentric shaft 5, and upper tool post 15 is also positioned at peak simultaneously.Then, motor 1 starts flywheel driven 2 to accelerate to rotate, and the eccentric part of eccentric shaft 5 accelerates to move downward together with upper tool post 15, and prepare for shearing metallic plate, in the process, kinetic energy is converted to the potential energy of flywheel 2 and stores by motor 1.Then, upper scissor blade on upper tool post 15 shears this metallic plate (shearing station), when shearing metallic plate, release is simultaneously used for shearing metallic plate by the kinetic energy of motor 1 and the potential energy of flywheel 2, and the energy storage effect just because of flywheel 2 just makes to adopt little motor to realize large shear ability becomes possibility.After having sheared metallic plate, motor 1 slows down and makes the eccentric part of eccentric shaft 5 come back to peak, upper tool post 15 also comes back to peak place and prepares the next work period simultaneously, namely in a shearing work cycle of this start stop mode steel plate sample intelligent environment protection shearing equipment, the eccentric part of eccentric shaft 5 returns initial peak position after initial peak rotates one week, upper tool post 15 and upper scissor blade 21 also return initial peak position after initial peak drops to minimum point, motor 1 accelerates to maximal rate and then gets back to initial halted state after initial halted state starts.This shearing equipment drive control mode adopts start and stop duty, and the physical location of eccentric shaft 5 and upper scissor blade 21 is accurately controlled (eccentric shaft positioner 10 structure and principle have introduction later) by eccentric shaft positioner 10.Owing to adopting start stop mode control mode, this shearing equipment system energy consumption reduces greatly, and compared with equal class shearing equipment, this shearing equipment is more energy-conservation, more environmental protection.
