Abstract

The invention discloses a punching method of a tube hole set and a stamping die thereof. The method comprises the following steps of: setting a joggle die capable of moving up and down between an upper die and a lower die of a punching machine, wherein one side of the joggle die, which is opposite to a first punch head arranged on the upper die, is provided with a lower die port, and one side opposite to the lower die is provided with a second punch head; then aligning the lower die port with the first punch head and aligning the second punch head with the lower die; sheathing a tube on the joggle die; moving the upper die downwards, causing the upper die to drive the joggle die to move downwards after punching a hole of the upper surface of the tube by utilizing the first punch head of the upper die, and then punching the hole of the lower surface of the tube by utilizing the second punch head of the joggle die. When the first punch head punches the hole of the upper surface of the tube, the joggle die has the function of a concave die; and after the holes of the upper surface of the tube are punched by the first punch head, the joggle die has the functions of a convex die, and therefore, with the punching method, the punching of two holes of the upper surface and the lower surface of the tube can be accomplished in one procedure, thereby improving production efficiency.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is made and to further specify.

Fig. 1 shows first kind of 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 first drift 11 that is used for punching.Patrix 1 and counterdie 2 are the moulds on the existing punch press, and joggle die 3 can be arranged on the guide rail mechanism, also can be connected on the lever 5 as shown in Figure 6, drive joggle die 3 by lever 5 and realize moving up and down.Joggle die 3 is arranged between patrix 1 and the counterdie 2, and the side that this joggle die is relative with first drift 11 is provided with down die orifice 31, and a side relative with counterdie 2 is provided with second drift 32 that is used for punching.The bottom of patrix 1 also is provided with the projection 12 of downward protrusion, and after first drift 11 is gone out the hole of tubing 4 upper surfaces, this projection 12 will promote joggle die 3 and move downward.

The diel of first kind of embodiment is used for coaxial and hole group that the aperture is different on the punching press tubing, and therefore, the center line of first drift 11 and second drift 32 is located on the same line, and first drift 11 is different with the external diameter of second drift 32.Following die orifice 31 is a through hole, and the external diameter of the aperture of through hole 31 and first drift 11 is complementary, and runs through second drift 32.Because first drift 11 is coaxial with 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 simultaneously punching to be carried out at the two ends of tubing 4, thereby can further enhance productivity.

Fig. 2 shows second kind of embodiment of diel of the present invention, and the diel of second kind of embodiment is used for coaxial and hole group that the aperture is identical on the punching press tubing.Wherein, the center line of first drift 11 and second drift 32 is located on the same line, and first drift 11 equates with the external diameter of second drift 32.Following die orifice 31 is the single order trapezoidal hole.

Fig. 3 and Fig. 4 show the diel that is used for hole group that punching press disalignment and aperture the equate hole group different with being used for punching press disalignment and aperture respectively.In Fig. 3, first drift 11 is positioned on the different straight lines with the center line of second drift 32, and first drift 11 equates with the external diameter of second drift 32.In Fig. 4, first drift 11 is positioned on the different straight lines with the center line of second drift 32, and the external diameter of first drift 11 and second drift 32 does not wait.

The blanking method of tube hole set of the present invention may further comprise the steps:

Step 1, between the patrix 1 of punch press and counterdie 2, joggle die 3 moving up and down is set, the side that this joggle die 3 is relative with first drift 11 of being located at patrix 1 is provided with down die orifice 31, a side relative with counterdie 2 is provided with second drift 32, die orifice 31 is alignd with first drift 11, and second drift 32 aligns with counterdie 2;

Step 2 is set in tubing 4 on the joggle die 3, and makes the inwall of tubing 4 be close to the upper surface of joggle die 3;

Step 3, the operation punch press moves downward patrix 1, go out the hole of upper surface of tubing 4 at first drift 11 of patrix 1 after, make patrix 1 drive joggle die 3 and move downward, utilize second drift 32 of joggle die 3 to go out the hole of the lower surface of tubing 4.

In step 3, patrix 1 can move downward by the projection 12 promotion joggle dies 3 that are arranged on the patrix 1.Yet the present invention is not limited to this, also can be provided with one independently linkage drive joggle die and move downward.

In above-mentioned blanking method, described hole should not be limited to said outline line blind bore on the ordinary meaning.Fig. 5 shows the schematic diagram of the otch that utilizes diel stamping-out tubing of the present invention.In Fig. 5, use the diel of first kind of embodiment of the present invention, the position of first drift 11 and second drift 32 is moved on to the edge of tubing 4, can realize tubing 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 plays the effect of die when the hole of the upper surface of the first drift punching press tubing of patrix; And go out the hole of upper surface of tubing at first drift after, under the drive of patrix, move downward, play the effect of punch, and gone out the hole of the lower surface of tubing.Therefore, the present invention has reduced stamping procedure, and a step has been finished the punching press in upper and lower surperficial two holes of tubing, thereby has improved production efficiency, has reduced production cost, and under the coaxial situation in the hole on the upper and lower surface of needs, can realize more high-precision coaxial degree.
