Description

Pre-bending structure for round-covered part

Technical Field

The utility model belongs to the technical field of the mould structure, especially, relate to a package circle part preflex structure.

Background

At present, the most widely used tool in the process of stamping and bending hardware is a bending die, as shown in fig. 1, a part a of the hardware is connected with a part B of the hardware, the part B is cylindrical after being wrapped by a circle, the part a needs to be bent at present, but the part a cannot be bent due to shielding of the part B, and a pre-bending structure for the wrapped-circle part is provided for solving the technical problem.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide a circle of packet part structure of bending in advance, can provide sufficient space of bending for the product part of bending, improve the quality of bending of product, improve the mould efficiency of bending

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a peripherical part is bending structures in advance, includes the mould body, the lower mould of mould body is provided with down the mould and goes into the son, the son top is provided with to bend down and dodges the recess, the last mould elastic mounting of mould body is used for pressing down the product and makes it fall into to bend and dodge the kicking block in the groove, the kicking block lateral part is provided with and is used for waiting to bend the part to the product and go up the mould punching pin that bends, the kicking block is prior to last mould punching pin contact product.

Compared with the prior art, the utility model discloses realize following beneficial effect:

the utility model discloses a set up mould punching pin, kicking block, lower mould and go into the son and bend and dodge the groove in the mould, and make the kicking block be prior to mould punching pin contact product, press the product through the kicking block, for the product part of bending reserves sufficient space, guarantee the quality that the product was bent, improve the product efficiency of bending.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples

Referring to fig. 1-4, a pre-bending structure for a rounded part comprises a die body, wherein a lower die of the die body is provided with a lower die insert 10, the top of the lower die insert 10 is provided with a bending avoiding groove 11, an upper die of the die body is elastically provided with a floating block 30 used for pressing a product to enable the product to fall into the bending avoiding groove, the side part of the floating block 30 is provided with an upper die punch 20 used for bending a part of the product to be bent, and the floating block 30 is in contact with the product before the upper die punch 20.

In this embodiment, the part B of the product 50 has a hollow cylindrical structure formed by a round, and in order to prevent the floating block 30 from breaking the part B structure by pressure during the lowering process, the floating block is elastically connected to the upper mold plate seat through the return spring 40, and in order to further protect the surface of the part B of the product, the bottom of the floating block 30 is provided with a round bevel edge 31.

In this embodiment, it is provided with the position of letting portion 21 that possesses the product B part of dodging to go up mould punch 20 and be close to floating block one side, and through setting up position of letting portion 21, not only further avoid last mould punch 20 to destroy product B part at the in-process that descends, also be favorable to guaranteeing bending of product a part moreover, further improve work efficiency.

In the specific implementation process, when the mold is closed, the upper mold of the mold moves downwards to close the lower mold, in the process of moving downwards of the upper mold, the floating block 30 contacts the part B of the product in advance with the upper mold punch 20 and presses the part B of the product downwards to make the joint of the part A and the part B out, and then the upper mold punch descends to bend the part A; when the mold is opened, the upper mold moves upwards, and the upper mold punch 20 and the floating block 30 move upwards along with the upper mold to be away from the product.

The utility model discloses a set up mould punching pin 20, kicking block 30, lower mould and go into sub 10 and bend and dodge groove 11 in the mould, and make kicking block 30 earlier than last mould punching pin 20 contact product, press product 50 through the kicking block, for product 50 bending part reserves sufficient space, guarantee the quality that the product was bent, improve the product efficiency of bending.

The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which should not limit the scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
