[0002] Hook punching machine refers to special punching equipment used to manufacture various types of hooks. These hooks are widely used in hardware, home furnishing, decoration, logistics, automobile and other industries. The punching machine applies pressure to metal sheets through the mold to complete the cutting, punching, forming and other processes, thereby efficiently producing hooks of different shapes and specifications.

[0003] With the development of technology, more and more automatic loading and unloading mechanisms are used in stamping production, and the production efficiency has been greatly improved. However, due to the structural limitations of the stamping machine, the height of the stamping die is generally higher than the height of the stamping machine table, and the external loading or unloading mechanism cannot be directly connected to the stamping die, otherwise it will interfere with the stamping process.

A compression spring 17 is also provided on the outer surface of the cross bar 15, and the two ends of the compression spring 17 are respectively connected to the support plate 14 and the inner side of the movable disk 16. The mounting frame 13 is fixed to one side of the lower template 3 by bolts, and a plurality of threaded holes are provided on one side of the lower template 3. The height of the mounting frame 13 can be adjusted according to the positions of the plurality of threaded holes, thereby adjusting the installation position of the movable disk 16. For different positions and thicknesses of metal sheets, the contact area between the edge of the movable disk 16 and the metal sheet is adjusted to improve the blocking effect on the transportation of the metal sheet.

[0042] It should be noted that a discharge hopper 29 is also provided at the end of the lower template 3, and the discharge hopper 29 is located on one side of the mounting frame 13. One end of the discharge hopper 29 is detachably mounted to the lower template 3 by bolts, and the other end of the discharge hopper 29 is inclined toward the horizontal plane and is elastic.
