Description

Stamping die structure of low punching press burr

Technical Field

The utility model relates to a punching press technical field especially relates to a stamping die structure of low punching press burr.

Background

In the etching and stamping process, the copper material passes through the stamping die, the upper die is lifted, the feeding mechanism carries out copper material conveying, the stamping punch falls along with the upper die after the copper material is positioned, a stamping hole is formed, and a stamping process is completed.

In the stamping process, due to factors such as equipment vibration and a die structure, the stamping punch cannot be guaranteed to fall vertically and lift vertically, a certain inclination exists, when the stamping punch falls obliquely or lifts obliquely, burrs can appear at the edge of the stamping hole, the generated burrs follow a copper material to perform subsequent production, when subsequent exposure is performed, an exposure machine uses the stamping hole to perform positioning, the positioning pin is inserted into the stamping hole at the moment to cause the burrs to fall off, and the fallen burrs enter an exposure die along with the copper material to cause poor exposure and influence the product quality.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a stamping die structure of low punching press burr, can prevent effectively that punching press hole edge from producing the burr in the stamping process, and the burr drops and causes the bad problem of exposure in the exposure production process, has effectively improved production quality and production efficiency.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a stamping die structure of low punching press burr, includes mould and bed die, go up the three guide pillar group that is provided with the triangle between mould and the bed die, each guide pillar group is including the guide arm, the guide arm overcoat is equipped with reset spring, the one side that goes up the mould and be close to the direction of feed is provided with the drift, the drift includes location drift and main drift, be provided with on the bed die with drift complex die-cut.

Preferably, the three guide post groups are respectively two main guide posts and one auxiliary guide post, and the auxiliary guide posts are arranged far away from the feeding direction.

Preferably, a ball bearing sleeve is arranged between the guide rod and the upper die.

Preferably, a waist-shaped hole is formed in one side, close to the feeding direction, of the upper die along the length direction, and the positioning punch is arranged in the waist-shaped hole.

The beneficial effects of the utility model are that: the utility model provides a pair of stamping die structure of low punching press burr has adjusted the structural design between last mould and the bed die, and the structural design of mould is more stable, effectively prevents to rock the problem of the punching press drift that leads to and copper product out of plumb because of the mould in stamping process, has reduced the bad loss of exposure that leads to because of punching press hole burr, has not only improved product quality, has improved production efficiency moreover.

Drawings

Fig. 1 is a schematic view of a structure of a stamping die with low stamping burrs according to the present invention;

fig. 2 is a schematic structural view of the upper waist-shaped hole inner punch of the upper die of the utility model;

FIG. 3 is a schematic structural view of the upper guide post of the middle and lower molds of the present invention;

the parts in the drawings are numbered as follows:

1. an upper die; 2. a lower die; 3. a guide bar; 4. a return spring; 5. positioning the punch; 6. a main punch; 7. notching; 8. a main guide post; 9. an auxiliary guide post; 10. a ball bearing sleeve; 11. a kidney-shaped hole.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Example (b):

as shown in fig. 1, a stamping die structure of low punching press burr, including last mould 1 and bed die 2, the guide pillar between last mould and the lower mould is two under the conventional conditions, single linear punching press is because of equipment vibrations easily, factors such as mould structure cause the punching press drift to appear the slope, arouse punching press hole edge burr, this scheme sets up three guide pillar group between last mould 1 and bed die 2, and be the triangle and arrange, this kind of structural design has effectively increased the stability of mould structure, effectively prevent to be out of plumb state because the mould rocks the punching press drift that causes and copper product in the punching press process.

As shown in fig. 1 and 3, the three guide post groups are two main guide posts 8 and one auxiliary guide post 9 respectively, the auxiliary guide post 9 is far away from the feeding direction, the feeding is prevented from being influenced, each guide post group comprises a guide rod 3, a reset spring 4 is sleeved outside the guide rod 3, and the original position is restored after the punching of the die is completed in the assistance of the reset spring. Further, in order to reduce friction between the return spring 4 and the upper die 1, a ball bushing 10 is provided between the guide bar 3 and the upper die 1.

As shown in fig. 1, 2 and 3, a punch is arranged on one side of the upper die 1 close to the feeding direction, a punching groove 7 matched with the punch is arranged on the lower die 2, and the punching hole forming process of the copper material is realized through the matching of the punch and the punching groove 7. The drift includes location drift 5 and main drift 6, and during the pay-off, mould 1 lifts up in the punching press, and in the copper product passed through the gyro wheel and got into stamping die, the copper product was fixed a position through location drift 5, and main drift 6 carries out the punching press hole shaping action to the copper product along with last mould 1 together. Further, in order to flexibly adjust the distance between the punches and meet diversified production requirements, a waist-shaped hole 11 is formed in one side, close to the feeding direction, of the upper die 1 along the length direction, and the positioning punch 5 is arranged in the waist-shaped hole 11.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
