Abstract
The invention discloses an anti-sticking material device with a hole-punching and a hole-flanging functions, comprising a punch head, a female die and a hole-flanging inner separation block. The anti-sticking material device is characterized in that the punch head comprises a cutter bar and a cutter head connected with the cutter bar, wherein the cutter head comprises a front cutter head used for punching a hole and a main body part used for flanging the hole, and the cylinder diameter of the main body part is more than that of a front cylinder; the female die comprises a hole-flanging female die and a hole-punching female die, wherein a through hole is arranged in the hole-flanging female die, the hole-flanging inner separation block is arranged in the through hole, the hole-punching female die is arranged on the hole-flanging inner separation block, and a blanking through hole is arranged in the hole-punching female die. When the punching and the flanging are carried out in the prior art, a punched bottom hole does not have the female die; in the production process, the small hole-punching waste materials are adhered to the hole-flanged opening and are difficultly removed; because the inner separation block is arranged in the hole-flanging female die and the hole-punching female die is increased on the inner separation block, the problem of the waste materials during hole flanging is solved; and the invention has simple structure and is easily applied to production operation.
Description
Technical field
The present invention relates to the diel field, specifically is that a kind of punching adds the antiseized materials device of hole flanging.
Background technology
In the plant produced, when rapidoprint being done punching adding flange hole technology, towards little bottom outlet generally is not use die, in operation process, the little waste material that will produce punching sometimes is bonded at the situation of hole flanging oral area, can not remove, therefore just need a kind of die device that can solve the band waste problems.
Summary of the invention
In order to realize above-mentioned technical purpose, the invention provides a kind of punching and add the antiseized materials device of hole flanging, comprise in drift, die, the hole flanging and take off piece, it is characterized in that:
Described drift comprises knife bar and the cutter head that is connected with knife bar, and described cutter head comprises anterior cutter head that is used for punching and the main part that is used for hole flanging, and the cylinder diameter of described main part is greater than the cylindrical diameter of described anterior cutter head; Described die comprises hole flanging die, punching concave die, is provided with a through hole in the described hole flanging die, is provided with in the through hole and takes off piece in the hole flanging; Described punching concave die is located at takes off in the hole flanging on the piece, and the punching concave die bottom is provided with the through hole of blanking.
Further technical scheme comprises:
Described through hole comprises two parts of size, and preceding through-hole diameter is less than the diameter of back through hole; Take off piece in the hole flanging and be made as and the corresponding trapezoidal column of through hole, be inserted in the described through hole, the rear end of taking off piece in the hole flanging is stuck on the through-hole wall of through hole front, back.
The diameter that takes off the piece front end in the described hole flanging equals the diameter of preceding through hole, takes off the piece rear end in the hole flanging and is provided with the circular chuck that a diameter equals rear through hole.
Take off the piece bottom in the described hole flanging and be provided with the elastic reset device.
The transition connecting portion of described anterior cutter head and main part is the arc shape of evagination.
The present invention takes off piece by being provided with in the hole flanging in the hole flanging die, 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, the waste material of punching is discharged by 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 an initial position structural representation of the present invention;
Fig. 2 is the positional structure schematic diagram that kills of the present invention.
The specific embodiment
In order to illustrate technical scheme of the present invention and technical purpose, the present invention is done further introduction below in conjunction with the drawings and the specific embodiments.
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,
Described drift comprises knife bar 11 and the cutter head 12 that is connected with knife bar 11, described 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 described 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.Described die comprises hole flanging die 2, punching concave die 4, is provided with a through hole 21 in the described hole flanging die 2, is provided with in the through hole and takes off piece 3 in the hole flanging; Described 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.
Described 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 described 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 described hole flanging equaled in the hole flanging, and described 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 described hole flanging and be provided with the elastic reset device.
At first, at material plate upper punch aperture, towards saturating 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 with anterior cutter head 13, and waste material is discharged from the blanking through hole 41 in the punching concave die.When diameter during greater than the main part 14 contact materials of the cutter head 13 of front portion, 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 in the hole flanging to take off piece 3 after press down, main part 14 is finished hole flanging, withdraws from hole flanging die 2, takes off piece 3 in the hole flanging and resets, and ejects material.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
