Description

Technical Field

[0001] The utility model relates to a bending machine, in particular to a bending die for the bending machine. Background Art

[0002] The bending principle of the bending machine is to control the bending angle by the depth (bending depth) of the upper mold pressing the sheet in the die mouth of the lower mold, or to press the workpiece into a workpiece with the same angle as the mold. The bending mold on the bending machine is composed of different parts. The shape of the object is mainly processed by changing the physical state of the molding material. According to different processing requirements, different bending molds often need to be replaced during the production process.

[0003] Depending on the shape of the product, it is often necessary to bend the strip multiple times. The existing multiple bending operations often achieve product forming by bending multiple times in succession. The workload of this operation will increase in turn according to the complexity of the product shape, which also leads to a huge workload when processing products with complex shapes or tricky angles. Based on the above problems, the present invention was born. Utility Model Content

The first lower forming block in motion forms a linkage with the second lower forming block under the action of the second linkage component to drive the second lower forming block to move and perform a second bending process on the strip sheet.
