The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 shows the first embodiment of diel of the present invention.Diel of the present invention comprises patrix 1, counterdie 2 and joggle die moving up and down 3.Patrix 1 is provided with the first drift 11 for punching.Patrix 1 and counterdie 2 are the moulds on existing punch press, and joggle die 3 can be arranged on a guide rail mechanism, also can be connected on a lever 5 as shown in Figure 6, drive joggle die 3 to realize move up and down by lever 5.Joggle die 3 is arranged between patrix 1 and counterdie 2, and the side that this joggle die is relative with the first drift 11 is provided with lower die orifice 31, and a side relative with counterdie 2 is provided with the second drift 32 for punching.The bottom of patrix 1 is also provided with the projection 12 of downward protrusion, and after the first drift 11 is gone out the hole of tubular material 4 upper surfaces, this projection 12 moves downward promotion joggle die 3.
The diel of the first embodiment is for coaxial on punching press tubular material and the different hole group in aperture, and therefore, the center line of the first drift 11 and the second drift 32 is located on the same line, and the first drift 11 is different from the external diameter of the second drift 32.Lower die orifice 31 is a through hole, and the external diameter of the aperture of through hole 31 and the first drift 11 matches, and runs through the second drift 32.Because the first drift 11 is coaxial with the second drift 32, therefore, when using this diel punching press, can guarantee the axiality in upper and lower surperficial two holes of tubing.
In real work, as shown in Figure 1, usually adopt two cover diels punching to be carried out in the two ends of tubular material 4 simultaneously, thereby can further enhance productivity.
Fig. 2 shows the second embodiment of diel of the present invention, and the diel of the second embodiment is for coaxial on punching press tubular material and the identical hole group in aperture.Wherein, the center line of the first drift 11 and the second drift 32 is located on the same line, and the first drift 11 equates with the external diameter of the second drift 32.Lower die orifice 31 is single order trapezoidal hole.
Fig. 3 and Fig. 4 show respectively for the equal hole group of punching press disalignment and aperture and diel for the different hole group of punching press disalignment and aperture.In Fig. 3, the first drift 11 is positioned on different straight lines from the center line of the second drift 32, and the first drift 11 equates with the external diameter of the second drift 32.In Fig. 4, the first drift 11 is positioned on different straight lines from the center line of the second drift 32, and the external diameter of the first drift 11 and the second drift 32 is not etc.
The process for stamping of tubular material of the present invention, comprises the following steps:
In step 3, patrix 1 can move downward by the projection 12 promotion joggle dies 3 that are arranged on patrix 1.Yet the present invention is not limited to this, also can arrange one independently linkage drive joggle die to move downward.
In above-mentioned blanking method, described hole should not be limited to said outline line blind bore on ordinary meaning.
Fig. 5 shows the schematic diagram of the otch that utilizes diel stamping-out tubular material of the present invention.In Fig. 5, use the diel of the first embodiment of the present invention, the position of the first drift 11 and the second drift 32 is moved on to the edge of tubular material 4, can realize tubular material 4 otch, once can go out upper and lower two otch, and can guarantee the precision of these two otch.
Joggle die of the present invention, when the hole of the upper surface of the first drift punching press tubular material of patrix, plays the effect of die;
And at the first drift, go out behind the hole of upper surface of tubular material, under the drive of patrix, move downward, play the effect of punch, and gone out the hole of the lower surface of tubular material.Therefore, the present invention has reduced stamping procedure, and a step has completed the punching press in upper and lower surperficial two holes of tubular material, thereby improved production efficiency, reduce production cost, and in the situation that the hole on the upper and lower surface of needs is coaxial, can realize more high-precision coaxial degree.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claim of the present invention.
