Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of certain aspects of the utility model that are consistent with the details of the claims below.

The present utility model will be described in further detail below with reference to the drawings and examples for better understanding of the technical solutions of the present utility model to those skilled in the art.

Example 1

Referring to fig. 1-8, the embodiment provides a simple washer symmetrical 90-degree bending die, which comprises an upper die 2 and a lower die 1 matched with the upper die 2, wherein a positioning cavity 5 is formed in the center of the lower die 1, a spring 4 is arranged in the positioning cavity 5, and a positioning cushion block 3 for fixing a washer is arranged above the spring 4; the upper die 2 is provided with at least two bosses, and holes matched with the bosses are uniformly formed around the positioning cavity 5.

Specifically, the cross section of the positioning cushion block 3 is of an inverted T-shaped structure, the bottom end of the positioning cushion block is in contact with the spring 4, and the top end of the positioning cushion block passes through the positioning cavity 5 and is exposed on the upper surface of the lower die 1.

Specifically, a limiting step 7 matched with the positioning cushion block 3 with the inverted T-shaped structure is arranged in the positioning cavity 5, and the limiting step 7 is used for limiting the positioning cushion block 3 to pop out of the lower die 1.

Specifically, the positioning cavity 5 is a through hole provided with a limiting step 7, and the through hole is in clearance fit with the positioning cushion block 3.

Specifically, the positioning cushion block 3 is fixedly connected with the spring 4; the positioning cushion block 3 is made of alloy tool steel (Cr 12 MoV).

Specifically, the lower die 1 is further provided with a groove 6 for placing a gasket, and the depth of the groove 6 is smaller than or equal to the thickness of the gasket.

Specifically, when the upper die 2 and the lower die 1 are closed, the spring 4 is pressed by the positioning cushion block 3 to buffer.

Specifically, the bending die can be used for processing products such as washers, locking plates and the like.

The embodiment also provides a simple application method of the gasket symmetrical 90-degree bending die, which comprises the following steps:

Before the bending die is used, the positioning cushion block 3 and the spring 4 are fixed and then are arranged in the positioning cavity 5, and the spring 4 is fixed, as shown in fig. 6; at the same time, the upper die 2 and the lower die 1 are clamped, and then the die is mounted on a punch press, so that the die can be processed. During processing, a positioning hole of a gasket passes through the top end of a positioning cushion block 3 (the top end of a vertical part in an inverted T-shaped structure) and is placed in a groove 6 of a lower die 1, and then an upper die 2 falls to the lower die 1 along with a punch to bend the gasket; when the upper die 2 presses down the positioning cushion block 3, the positioning cushion block 3 is pressed to drive the spring 4 to slowly retract into the positioning cavity 5, and when the upper die 2 and the lower die 1 are closed, the upper die 2 moves upwards again to return to the original position, and at the moment, the positioning cushion block 3 returns to the original position under the action of potential energy of the spring 4, so that the gasket is bent; because the gasket is limited by the positioning cushion block 3 and the groove 6, the gasket cannot shake randomly during processing, and the position and the size of the processed gasket are ensured to meet the requirements; the finished gasket is shown in fig. 9.

The foregoing is only a specific embodiment of the utility model to enable those skilled in the art to understand or practice the utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.

It will be understood that the utility model is not limited to what has been described above and that various modifications and changes may be made without departing from the scope thereof. The scope of the utility model is limited only by the appended claims.
