Problems solved by technology
In addition to being able to shape the workpiece, stamping also has the function of stamping and cutting, that is, the workpiece can be punched down according to the set formation, such as punching a circular felt sheet, and punching through a cylindrical cutter head, in which the felt is pre-wound on the On the reel, when the driving wheel pulls the felt to move, the reel rotates to release the felt, but when the reel is wound with more felt, the weight is heavy, that is, the inertia is large, so it is difficult to pull the reel to rotate smoothly, causing the felt to move Inaccurate enough to affect stamping quality

Embodiment Construction
[0019] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0020] like figure 1 , figure 2 As shown, a blank drawing mechanism of a punching machine, the punching machine includes a frame 1, a punching platform 11 is fixedly connected to the frame 1, one end of the punching platform 11 is a feed end 12, and the blank pulling mechanism includes The positioning shaft 21 is used for the fixed sleeve of the felt reel. The feed end 12 of the stamping platform 11 is slidably connected to the moving frame 2 along the length direction. Two positioning seats 3 are slidingly connected to the upper side along the vertical direction, and a discharge cylinder 4 is fixedly connected to the lower side of the stamping platform 11, and a piston rod for the discharge cylinder 4 is arranged betwee...

The invention provides a sheet pull-out mechanism of a punching machine and belongs to the technical field of mechanical equipment. The problem that the quality is low when an existing punching machine punches felt is solved. The punching machine comprises a rack; the rack is fixedly connected with a punching platform; a charging barrel positioning mechanism comprises a positioning shaft; the feeding end of the punching platform is in sliding connection with a movable frame; the positioning shaft is rotationally connected with the movable frame; the upper side face of the feeding end of the punching platform is in sliding connection with two positioning bases; the lower side face of the punching platform is fixedly connected with a discharging cylinder; a transmission part is arranged between the discharging cylinder and the positioning bases; the end portion of a piston rod of the discharging cylinder is further fixedly connected with an ejector rod; and the punching platform is further provided with a reset tension spring capable of making the movable frame reset and move. The sheet pull-out mechanism of the punching machine can make a coiling block rotate to automatically release the felt and improve the punching quality.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a sheet pulling-out mechanism of a stamping machine. Background technique [0002] In the general sense, the punching machine drives the flywheel through the motor, and drives the crank linkage mechanism through the clutch and the transmission gear to move the slider up and down, and drives the stamping die to stamp the workpiece. In addition to being able to shape the workpiece, stamping also has the function of stamping and cutting, that is, the workpiece can be punched down according to the set formation, such as stamping a circular felt sheet, and punching through a cylindrical cutter head, in which the felt is pre-wound on the On the reel, when the driving wheel pulls the felt to move, the reel rotates to release the felt, but when the reel is wound with a lot of felt, the weight is heavy, that is, the inertia is large, so it is difficult to pull the reel to rotat...
