The utility model takes off piece through in the hole flanging die, being provided with in the hole flanging; In hole flanging, take off the die of setting up punching on the piece; Waste material when efficiently solving punching is bonded at the defective of hole flanging oral area, and the waste material of punching is discharged through the blanking through hole of punching concave die, has advantage simple in structure, easy to use; Be easy in production operation, apply, improve the hole flanging yield of products greatly.
Description of drawings
Fig. 1 is the initial position structural representation of the utility model;
Fig. 2 be the utility model kill the positional structure sketch map.
The specific embodiment
For technical scheme and the technical purpose of illustrating the utility model, the utility model is done further introduction below in conjunction with the accompanying drawing and the specific embodiment.
As shown in the figure, a kind of punching adds the antiseized materials device of hole flanging, comprise taking off piece 3 in drift, die, the hole flanging,
Said drift comprises knife bar 11 and the cutter head 12 that is connected with knife bar 11; Said cutter head 12 comprises anterior cutter head 13 that is used for punching and the main part 14 that is used for hole flanging; The diameter of the barrel portion of main part 14 is greater than the diameter of said anterior cutter head 13 barrel portions; Anterior cutter head 13 is the arc shape of evagination with the transition connecting portion of main part 14, and the transition connecting portion of knife bar 11 and main part 14 is made as the arc shape of indent.Said die comprises hole flanging die 2, punching concave die 4, is provided with a through hole 21 in the said hole flanging die 2, is provided with in the through hole and takes off piece 3 in the hole flanging; Said punching concave die is located at takes off in the hole flanging on the piece 3, and punching concave die 4 bottoms are provided with the through hole 41 of blanking.
Said through hole 21 comprises two parts of size, and preceding through-hole diameter is less than the diameter of back through hole; Take off piece 3 in the hole flanging and be made as and through hole 21 corresponding trapezoidal columns, be inserted in the said through hole 21.The diameter of through hole took off piece 3 rear ends and is provided with the circular chuck 31 that a diameter equals rear through hole before the diameter that takes off piece 3 front ends in the said hole flanging equaled in the hole flanging, and said circular chuck 31 is stuck on the through-hole wall of through hole front, back, to take off the position of piece 3 in the fixing hole flanging.
Take off piece 3 bottoms in the said hole flanging and be provided with the elastic reset device.
At first, with anterior cutter head 13 on material plate towards aperture, dash to pass through the material thickness of slab, anterior cutter head stretches in the punching concave die 4 of taking off in the hole flanging on the piece 3, waste material is discharged from the blanking through hole 41 in the punching concave die.When diameter during greater than the main part of the cutter head 13 of front portion 14 contact materials, the beginning hole flanging.Because main part 14 diameters are greater than anterior cutter head 13, the arcuate front ends of main part 14 is against on the die mouth of punching concave die, drives to take off piece 3 in the hole flanging after press down, main part 14 is accomplished hole flanging, withdraws from hole flanging die 2, takes off piece 3 in the hole flanging and resets, and ejects material.
