[0002] A wire bending machine is a device that bends metal wire into specific shapes. It's used for bending wire in automotive parts, kitchen and bathroom hardware, and other household hardware products. In practice, wire bending machines frequently require mold changes, which is cumbersome to do manually, and existing automated mold-changing systems are complex. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide an inner die replacement mechanism for a wire bending machine, which has a simple structure and is easy to use on the wire bending machine.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a folding machine inner mold replacement mechanism, comprising a bracket, on which an inner mold, an outer mold and a replacement cylinder group are provided, the inner mold is arranged in the outer mold, the replacement cylinder group includes a first cylinder and a second cylinder, the cylinder bodies of the first cylinder and the second cylinder are fixedly connected and arranged in opposite directions, and the first output shaft of the first cylinder is connected to the inner mold.

[0005] In the above technical solution, a cylinder support plate is provided on one side of the bracket, and the transposition cylinder is assembled on the cylinder support plate.

[0006] In the above technical solution, the second output shaft of the second cylinder is fixedly connected to the cylinder support plate.

[0007] In the above technical solution, the first cylinder and the second cylinder work independently, and the extension directions of the output shafts are opposite.

[0008] In the above technical solution, the inner mold includes a die head and a linkage rod, and the linkage rod is fixedly connected to the first output shaft.

[0009] In the above technical solution, a guide tube is provided in the bracket, a plurality of bearings are provided on the outer periphery of the guide tube, and the linkage rod is provided in the guide tube.

[0010] To sum up, the technical solution of the present invention has the following beneficial effects compared with traditional technical means: the present invention controls the position of the inner mold through the transposition cylinder group to make it reach the corresponding work position, and fixes the first cylinder and the second cylinder body together. The first cylinder and the second cylinder can be controlled individually to move, or the two cylinders can be moved at the same time, thereby pushing the inner mold of the folding machine fixed on the transposition cylinder group to move back and forth, so that it reaches the work position required for folding. When the inner mold reaches the corresponding work position, it can cooperate with the outer mold to complete different processes in the bending and forming process.
