The movable die head 32 is designed movably, the base die 321 is arranged on the mounting seat 31, the mounting seat 31 drives the base die 321 and the stamping die 322 to move through transmission, a workpiece is stamped, the stamping die 322 is limited through a clamping block 323 in the decompression cavity 3211, when the die head moves upwards, the base die 321 moves upwards first, the stamping die 322 and the base die 321 move upwards with a time difference, so that the bottom dead center of stamping is automatically maintained, and the forming quality is improved.
As an optimization, a return spring 33 is arranged in the decompression cavity 3211, and one end, away from the wall surface of the decompression cavity 3211, of the return spring 33 is abutted against the clamping block 323. Through setting up reset spring 33 in decompression cavity 3211, reset spring 33 other end and fixture block 323 are connected, when carrying out the work piece of different specifications and punching press, the work piece that thickness is thicker, the time that bottom dead center needs to keep is longer after punching press is accomplished, during punching press, through driving motor 21 and toggle transmission structure, make die 322 pass the through-hole on the work piece, the thicker work piece, then the tensile deformation volume is bigger, the pulling force between die 322 and the work piece is bigger, after punching press is accomplished, mount pad 31 drives basic mould 321 and moves upwards, make fixture block 323 in die 322 upper end slide in decompression cavity 3211, produce relative slip between basic mould 321 and the die 322, and carry out tensile to reset spring 33, when the tensile force that reset spring 33 is greater than the frictional force between die 322 and the work piece, the bottom dead center keeps and ends, thereby can be according to the work piece automatically regulated bottom dead center hold time of different thickness.
Preferably, the vertical height of the relief cavity 3211 is greater than the length of the upper section of the die 322. In the stamping die head, the bottom surface of the base die 321 can be contacted with the stamping die 322, so that the transmission stability is ensured.
The working principle of the invention is as follows: the offset electric cylinder 27 is installed through the locating groove 221 on the driving wheel 22, the offset electric cylinder 27 outputs displacement to drive the eccentric wheel 23 to linearly move, and the distance between the eccentric wheel 23 and the axis of the driving wheel 22 can be adjusted, so that when the eccentric wheel 23 rotates, the swing amplitude of the pitch rod 24 is changed, and the up-and-down displacement of the driving seat 26 is different, so that workpieces with different specifications are punched; the waste is sucked into the material guide cavity 14 through the material guiding electromagnet 46 and finally discharged between the floating seat 41 and the supporting seat 45, the lower side of the floating seat 41 is supported in an auxiliary mode through punched waste, when punching and blanking are carried out, the movable die head 32 locally punches a workpiece to form waste, the movable die head 32 moves downwards continuously and drives the floating seat 41 to move downwards, the waste between the floating seat 41 and the supporting seat 45 is punched, crushed and shaped, a plurality of waste are integrated into a whole through volume reduction molding, collection is facilitated, and because the strength of the waste at the lower side is smaller than that of the movable die head 32, gaps exist among the waste, part of energy which can be punched in the punching process is converted into deformation quantity of the waste, impact in the punching process is reduced, meanwhile, the strength of the bottom is weaker than that of the movable die head 32 because the bottom is supported through the waste, and the service life of the movable die head 32 is guaranteed.
While embodiments of the present invention have been shown and described, it will be understood that the above embodiments are illustrative and not to be construed as limiting the invention, and that variations, modifications, alternatives, and variations may be made to the above embodiments by those of ordinary skill in the art without departing from the spirit and principles of the invention.
