[0003] A stamping die refers to a die for stamping parts (usually metal parts), and generally has structures such as an upper seat plate and a lower template that can move relative to each other. There is a workpiece to be processed, which has a first section and a second section connected to each other and needs to be bent. For the existing stamping die for bending, generally, structures such as a punch are required, and under the drive of the upper seat plate, it performs up and down stamping operations relative to the lower template, and the workpiece is bent with poor accuracy. Or in another stamping die, it is necessary to cooperate with mechanisms such as adjusting pins and adjusting inserts to make the insert squeeze and move the workpiece. The overall structure is complex, the number of components is large, and the maintenance cost is high.

[0028] Please refer to Figures 1-3 , which is a bending adjustment device for this embodiment, used for bending a workpiece 100. Among them, the workpiece 100 includes a connected first section 101 and a second section 102; and the bending adjustment device includes:

[0029] An upper seat plate 1, an upper backing plate 2, an upper clamping plate 3, a stop plate 4, an upper stripping plate 5, and a lower template 6 that are stacked from top to bottom. There is a cavity between the lower template 6 and the upper stripping plate 5;

[0030] A lower die insert mechanism 7. The insert mechanism 7 is in the cavity. The lower die insert mechanism 7 includes a first lower die insert 71 and a second lower die insert 72. The first lower die insert 71 has a first inclined wall, the second lower die insert 72 has a second inclined wall, and the first inclined wall and the second inclined wall are arranged oppositely;

[0031] A punch mechanism 8. The punch mechanism 8 includes an adjusting punch 81 and an adjusting punch insert 82. One end of the adjusting punch 81 is clamped by the upper clamping plate 3. A chute is provided at the other end of the adjusting punch 81. The adjusting punch insert 82 has a slide rail matching the chute, and the adjusting punch insert 82 is slidably mounted on the adjusting punch 81; the adjusting punch insert 82 has an oppositely arranged bending surface and a third inclined wall;

[0032] Among them, the first section 101 of the workpiece 100 is clamped between the upper stripping plate 5 and the first lower die insert 71. The third inclined wall abuts against the second inclined wall, the bending surface abuts against the second section of the workpiece 100, and the second lower die insert 72 is connected to a lifting mechanism for lifting the second lower die insert 72. When the second lower die insert 72 is lifted by the lifting mechanism, the third inclined wall and the second inclined wall slide relatively, the adjusting punch insert 82 slides in the direction towards the workpiece 100 relative to the adjusting punch 81, and the second section 102 of the workpiece 100 is extruded by the bending surface.

[0033] For the above structure, during installation, it is necessary to pay attention to stacking the upper seat plate 1, the upper backing plate 2, the upper clamping plate 3, the stop plate 4, the upper stripping plate 5, and the lower template 6 in this order along the direction of the unified projection plane of the side. The lower die insert mechanism 7 is arranged in the cavity at the lower template 6. The adjusting punch insert 82 is arranged at the position between the first lower die insert 71 and the second lower die insert 72, and the upper stripping plate 5 and the first lower die insert 71 are used to pre - compress the first section 101 of the workpiece 100.

[0034] With the above structure, during use, the operator only needs to lift the second lower die insert 72 by a lifting mechanism (not shown in the figure) below it, causing the second lower die insert 72 to displace perpendicular to the projection plane. Then, the third inclined wall at the top of the second lower die insert 72 squeezes the second inclined wall of the adjusting punch insert 82. Since the adjusting punch insert 82 is limited by the adjusting punch 81, a relative displacement occurs between the slide rail of the adjusting punch insert 82 and the chute of the adjusting punch 81, and the adjusting punch insert 82 moves along the direction of the workpiece 100, causing the bending surface of the adjusting punch insert 82 to squeeze the second section 102 of the workpiece 100. During the squeezing process, since the first section 101 of the workpiece 100 is clamped and fixed, the second section 102 of the workpiece 100 rotates and deforms in the direction towards the first lower die insert 71 under the push of the adjusting punch insert 82, causing the workpiece 100 to be bent.

[0035] In the above process, if it is necessary to control the bending angle of the workpiece 100, the lifting height dimension of the second lower die insert 72 can be directly controlled, which is indirectly converted into different degrees of squeezing of the second section 102 of the workpiece 100. At the same time, if it is necessary to adjust the bending speed of the second section 102 of the workpiece 100 to improve the accuracy, the slopes of the third inclined wall of the second lower die insert 72 and the second inclined wall of the adjusting punch insert 82 can be adjusted. Replacing the parts with a more gentle slope can reduce the bending speed of the second section 102 of the workpiece 100, greatly improving the bending accuracy and also expanding the applicable range of this embodiment.

[0036] In one embodiment, the lifting mechanism is set as a gasket, and the cavity at the bottom of the second lower die insert 72 includes a reserved space for accommodating the gasket. Specifically, the gasket can be made of a metal sheet or other materials, and the thickness can be adjusted according to needs. The gasket adjustment is simple and economical, and is suitable for situations where the height of the second lower die insert 72 needs to be finely adjusted.

[0037] In another embodiment, the lifting mechanism is set as a hydraulic cylinder, and the output end of the hydraulic cylinder is connected to the bottom of the second lower die insert 72 so that the second lower die insert 72 can be lifted or lowered by the hydraulic cylinder. This method is usually used in operating environments that require automatic adjustment or frequent adjustment. Although the cost is high, the bending efficiency and stability are also high, and it can be selected according to needs.

[0038] Furthermore, the inclination angles of the second inclined wall and the third inclined wall match each other so that the second lower die insert 72 fits with the adjusting punch insert 82. Specifically, the inclination angles of both the second inclined wall and the third inclined wall are set to 45 degrees. With the above structure, whenever the second lower die insert 72 is lifted by a preset height, the adjusting punch insert 82 will also slide horizontally by the same preset distance, making the bending angle in this embodiment easy to control.

[0039] Furthermore, the length of the first inclined wall matches the length of the second section 102 of the workpiece 100. At the same time, the angle of the first inclined wall is the same as the preset target bending angle of the workpiece 100. That is to say, when the punch insert 82 is adjusted to extrude the second section 102 of the workpiece 100, the second section 102 can be extruded to fit onto the first inclined wall of the first lower die insert 71, so that the first inclined wall limits the bending angle of the workpiece 100, and the bending accuracy can be improved. Of course, the first inclined wall can also be a special-shaped surface, such as an arc, etc., so that the second section 102 of the bent workpiece 100 is formed into a specified shape, improving the processing efficiency.

[0040] The content disclosed above is only the preferred feasible embodiment of the present invention, and does not limit the scope of the patent application of the present invention. Therefore, all equivalent technical changes made by using the description and drawings of the present invention are included in the scope of the patent application of the present invention.

[0041] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, reference can be made to each other. The key point of each embodiment is to illustrate the differences from other embodiments.

[0042] Although the present application is depicted through embodiments, those of ordinary skill in the art know that the present application has many variations and changes without departing from the spirit of the present application. It is hoped that the appended embodiments include these variations and changes without departing from the present application.
