The invention relates to a moving adjusting mechanism for a transverse cutting sub-die. The moving adjusting mechanism comprises moving air cylinders and compressing oil cylinders; the cylinder bodies of the moving air cylinders are fixed on a large die plate, and the piston rods of the moving air cylinders are connected on the shelf of the transverse cutting sub-die through thrust shafts; when the piston rods of the moving air cylinders are retracted, the transverse cutting sub-die is located at an odd-hole transverse cutting position or an even-hole transverse cutting position, and the travel of the piston rod of each moving air cylinder is one step; the cylinder bodies of the compressing oil cylinders are fixed on the lower part of the large die plate, the piston rods of the compressing oil cylinders upwardly pass through the large die plate and are connected with T-shaped blocks, the upper parts of the T-shaped blocks are connected with springs, and the other ends of the springs are compressed by pressing blocks; the shelf of the transverse cutting sub-die is provided with a first socket and a second socket which correspond to the T-shaped blocks, and when the transverse cutting sub-die is located at the odd-hole transverse cutting position or the even-hole transverse cutting position, the T-shaped blocks are respectively embedded into the first and the second sockets. Themoving adjusting mechanism with a simple and ingenious structure can conveniently, quickly and accurately adjust the position of the transverse cutting sub-die.
