Abstract
The invention discloses a concentric stamping die. The concentric stamping die comprises an upper die base, a lower die base and a punch, and is characterized by also comprising an upper pressing plate, a hole flanging female die and a lower stripping plate, wherein the hole flanging female die comprises an upper hole flanging female die and a lower hole flanging female die; the lower hole flanging female die is arranged under the upper hole flanging female die; a female die orifice circle center of the upper hole flanging female die and a female die orifice circle center of the lower hole flanging female die are positioned on the same axial line; the upper hole flanging female die is arranged between the upper pressing plate and the lower stripping plate; the lower hole flanging female die is arranged on the lower die base and is positioned below the lower stripping plate; a hole flanging inner stripping block is arranged on the hole flanging female die; the punch comprises an upper segment punching rod, a lower segment punching rod and a top end cutter bit; the diameter of the lower segment punching rod is less than that of the upper segment punching rod; and the punch has a trapezoid column shape. In the concentric stamping die, the punch is used for flanging two holes, so that the hole flanging concentricity is ensured; and the concentric stamping die has the advantages of simple structure and convenience of use, is easy to operate, and can effectively ensure the concentric accuracy of a part with a concentric hole.
Description
Technical field
The present invention relates to a kind of mould, specifically is a kind of mould that is used for the punching press concentric hole.
Background technology
Ask for something is provided with the workpiece of concentric hole; The axle center that requires the hole like the hole flanging on two end faces of workpiece or punching point-blank; When such workpiece is carried out punching press; Normally punching press is distinguished in two holes, but the change of the displacement of workpiece and punching press condition, be difficult to avoid producing between two holes deviation of concentricity.Car seat headrest dowel hole etc. for example, it is just very high to the requirement of concentricity in process of production.
Summary of the invention
In order to solve the problems of the technologies described above, guarantee the positional precision of workpiece concentric hole, the invention provides a kind of concentric diel, comprise upper bolster, die shoe and be arranged on the drift on the upper bolster, it is characterized in that:
The top board, hole flanging die and the lower stripper that also comprise binder; Said hole flanging die comprises hole flanging die and following hole flanging die; Said down hole flanging die be arranged on the hole flanging die under, the die mouth axle center of last hole flanging die and the die mouth axle center of following hole flanging die are on same axis;
The said hole flanging die of going up is arranged between top board and the lower stripper, and said hole flanging die down is arranged on the die shoe, is positioned at the lower stripper below, is provided with in the said hole flanging die down and takes off piece in the hole flanging;
Said drift comprises epimere jumper bar, lower end jumper bar and top cutter head, and said lower end jumper bar diameter is less than the epimere jumper bar, and said drift is trapezoidal column.
Further technical scheme comprises:
Said going up between hole flanging die and the lower stripper is provided with a limiting plate, and said limiting plate two ends respectively are provided with the limited post of perforation limiting plate in two ends about in the of, and said limited post top is connected with last holding pad, and its bottom is connected with lower stripper.Said limiting plate is used to control the mould of hole flanging and the distance between the following hole flanging mould.
Said axle center of going up hole flanging die and following hole flanging die die mouth is on same vertical straight line.
Take off the piece bottom in the said hole flanging and be provided with elasticity reset device.
The position that is connected between said epimere jumper bar and the hypomere jumper bar is made as the inclined-plane.
The present invention is through being provided with two cover dies up and down in the punching press; The part that workpiece need be processed concentric hole is individually fixed between top board and the last hole flanging die, the position between lower stripper and the following hole flanging die; The axle center that two cover die die mouths are set is on same axis; Through a punching press of drift, accomplish twice hole flanging up and down.The present invention has simple in structure, easy to operate advantage, has improved the concentric precision of concentric hole workpiece greatly, has improved product quality.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a plan structure sketch map 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 accompanying drawing and the specific embodiment.
As shown in the figure; A kind of concentric diel comprises upper bolster, die shoe and is arranged on the drift 1 on the upper bolster, also comprises top board 2, hole flanging die and the lower stripper 7 of binder; Said hole flanging die comprises hole flanging die 3 and following hole flanging die 5; Following hole flanging die 5 be arranged on hole flanging die 3 under, the die mouth axle center of last hole flanging die 3 and the die mouth axle center of following hole flanging die 5 are on same axis, and be as shown in Figure 1.
After setting the material position on the hole flanging die, said top board 2 is pressed on the material of hole flanging.Lower stripper 7 is positioned at the below that hole flanging die 3 is provided with, and is pressed in down on the hole flanging material.Said hole flanging die 5 down is arranged on the die shoe, is positioned at lower stripper 7 belows, and the axle center that makes hole flanging die 3 and following hole flanging die 5 die mouths is on same vertical straight line.Be provided with a limiting plate between last hole flanging die 3 and the lower stripper 7; Said limiting plate two ends respectively are provided with the limited post 4 of perforation limiting plate in two ends about in the of; Said limited post 4 tops are connected with top board 2, and its bottom is connected with lower stripper 7, are used for the control interval distance between two molds up and down.Be provided with in the said hole flanging die 5 down and take off piece 6 in the hole flanging, take off piece 6 bottoms in the hole flanging and be provided with elasticity reset device.
Said drift 1 comprises epimere jumper bar, hypomere jumper bar and top cutter head, and said hypomere jumper bar diameter makes drift 1 be trapezoidal column less than the epimere jumper bar, and the position that is connected between epimere jumper bar and the hypomere jumper bar is made as the inclined-plane.
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 replacement or the technical scheme that obtained of equivalent transformation mode, all drop within protection scope of the present invention.
