In an embodiment of the present utility model, the number of the first thread groove and the second thread groove is three, and the three first thread grooves and the second thread groove are respectively along the upper flange and the lower flange. The flanges are evenly spaced in the circumferential direction and arranged inside the upper flange and the lower flange.

In an embodiment of the present utility model, the center positions of the upper flange and the lower flange are provided with installation holes.

In one embodiment of the present utility model, the upper flange is detachably mounted on the servo press, hydraulic press or pneumatic press through mounting bolts, and the lower flange is detachably mounted on the corresponding on the head of each press.

In an embodiment of the present invention, the upper flange and the lower flange are both circular, and the materials of the upper flange and the lower flange are both low-temperature carbon steel.

As mentioned above, a press flexible connector of the present invention has the following beneficial effects:

The utility model can make the lower flange move upward by pressing the lower flange with the pressure head, so that the lower flange can squeeze the spring, and then make the spring elastically contract, so that the lower flange and the upper flange can be pressed tightly, realizing The indenter can float at any angle, has compensation and relative axis offset, and avoids the adjustment of the staff during subsequent reinstallation, and reduces the labor intensity of the staff. For the problem of relative axis, the structure is simple and the design is reasonable, so it is suitable for production and popularization and application.

Detailed ways

The implementation of the present utility model is illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

Please refer to Figure 1 to Figure 2. It should be noted that the structures, proportions, sizes, etc. shown in the drawings attached to this specification are only used to match the content disclosed in the specification, for those who are familiar with this technology to understand and read, and are not used to limit the implementation of the utility model Therefore, it has no technical substantive meaning. Any modification of structure, change of proportional relationship or adjustment of size shall still fall within the scope of The technical content disclosed by the utility model must be within the scope covered. At the same time, terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit this specification. The practicable range of the utility model, and the change or adjustment of its relative relationship, without any substantial change in the technical content, shall also be regarded as the practicable scope of the utility model.

Please refer to Fig. 1 and Fig. 2. The utility model provides a flexible connector for a press. The specific embodiment of the utility model is that it includes an upper flange 1, and a lower flange 2 is provided on the bottom side of the upper flange 1. The upper flange 1 is provided with a first thread groove 3, and the lower flange 2 is provided with a second thread groove 4, the first thread groove 3 and the second thread groove 4 correspond up and down, and the upper flange 1 and the lower flange 2 A fixing bolt 5 is provided, the bottom end of the fixing bolt 5 passes through the first thread groove 3 and is screwed into the second thread groove 4, and the surface of the fixing bolt 5 is covered with a spring 6 arranged in the second thread groove 4, Under the elastic action of the spring 6, there is a gap 8 between the upper flange 1 and the lower flange 2, and there is a 2mm gap 8 between the upper flange 1 and the lower flange 2, and the first thread groove 3 and the second thread groove 4 The number of each is three, and the three first thread grooves 3 and the second thread grooves 4 are evenly spaced inside the upper flange 1 and the lower flange 2 along the circumference of the upper flange 1 and the lower flange 2 respectively. ;

Specifically, since a gap 8 of 2 mm is reserved between the upper flange 1 and the lower flange 2, when a servo press, hydraulic press or pneumatic press is used to process the product, the pressure head is in contact with the product at this time , the product squeezes the pressure head, so that the pressure head squeezes the lower flange 2, so that the lower flange 2 moves upward, makes the lower flange 2 squeeze the spring 6, and then makes the spring 6 elastically contract until the lower flange 2 The flange 2 and the upper flange 1 are pressed tightly, so that the pressure head can float at any angle, with compensation and relative axis offset, and after the product is processed, under the action of the elastic elongation of the spring 6, the lower The flange 2 returns to its original position, which is convenient for the staff to operate and use.

A further embodiment is, please refer to Figure 1 and Figure 2, the center of the upper flange 1 and the lower flange 2 are provided with a mounting hole 7, the upper flange 1 is detachably mounted on the servo press, On the hydraulic press or pneumatic press, the lower flange 2 is detachably installed on the pressure head of each press through the mounting bolts. The upper flange 1 and the lower flange 2 are both circular, and the upper flange 1 and the The material of the lower flange 2 is low-temperature carbon steel.
