Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

As shown in fig. 1, an automobile panel stamping die pressing plate includes a pressing plate body 10, a stamping tool 11 of an upper die is installed below the pressing plate body 10, a superposed pre-pressing piece 20 is installed at the bottom of the pressing plate body 10, the pre-pressing piece 20 is arranged around the stamping tool 11, the pre-pressing piece 20 includes a first rod body 21 and a second rod body 22 which are hinged to each other, the upper end of the first rod body 21 is rotatably connected with the pressing plate body 10 through a pin, a torsion spring 23 for expanding the first rod body 21 is arranged at the connecting end of the first rod body 21 and the pressing plate body 10, the pre-pressing piece 20 further includes a spring 24 for expanding the first rod body 21 and the second rod body 22, one end of the spring 24 is fixedly connected with the first rod body 21, and the other end of the spring 24 is fixedly connected with the second rod body 22.

In this embodiment, a superposed prepressing element 20 is disposed below the pressure plate body 10 to prepress and fix the workpiece when the upper and lower dies are closed, so as to prevent the workpiece from deviating, and at the same time, the first rod 21 and the second rod 22 can be superposed and tightened at the final stage of prepressing, so as not to affect the closing of the upper and lower dies to punch the workpiece, and as the closing of the upper and lower dies is performed, the elastic potential energy of the torsion spring 23 and the spring 24 is stored more and more, and the pressing force on the workpiece is stronger.

In this embodiment, as shown in fig. 2 and 3, the first rod 21 and the second rod 22 are both prism-shaped, an included angle between center lines of the first rod 21 and the second rod 22 is an obtuse angle, and the first rod 21 and the second rod 22 are both provided with a beveled matching surface at a joint, the first rod 21 and the second rod 22 are connected by a hinge 25, a rotating shaft of the hinge 25 is disposed on an overlapped side of the first rod 21 and the second rod 22, as shown in fig. 3, a is an overlapped side of the first rod 21 and the second rod 22, and B is an overlapped back side.

The first rod body 21 and the second rod body 22 need to be automatically folded when pressed, so that the included angle of the central lines of the first rod body 21 and the second rod body 22 is an obtuse angle, the folding is more convenient, the inclined matching surface plays a role in limiting, the maximum included angle of the central lines of the first rod body 21 and the second rod body 22 is ensured to be an obtuse angle, and the hinge 25 is used for folding the first rod body 21 and the second rod body 22.

In this embodiment, as shown in fig. 2, the spring 24 is installed on the overlapped back sides of the first rod 21 and the second rod 22. The effect of spring 24 is at the elastic potential energy of storage when first body of rod 21 and the coincide of second body of rod 22 to improve the pressure of second body of rod 22 to the work piece, set up spring 24 at the coincide dorsal part, just can be at the in-process of the coincide of first body of rod 21 and second body of rod 22, through the extension spring 24 that opens of hinge 25, thereby make spring 24 store elastic potential energy, tie simple and practical.

In addition, as shown in fig. 2, a ball-shaped ram 221 is provided at the lower end of the second rod 22. The pre-pressing piece 20 is of an overlapped structure, a situation that a contact point of the second rod body 22 and a workpiece is deviated in the process of closing the upper die and the lower die can exist, and the spherical pressing head 221 is arranged at the lower end of the second rod body 22 to prevent the second rod body 22 from scratching the workpiece in the process of closing the upper die and the lower die.

In this embodiment, as shown in fig. 1, the bottom of the pressure plate body 10 is provided with an accommodating groove 12 adapted to the pre-pressing member 20. Make pre-compaction piece 20 become the hidden structure of compound die through setting up holding tank 12, reduced the influence of pre-compaction piece 20 to the work piece punching press more, need not adjust the height of pressing flitch body 10 simultaneously.
