[0046] Working principle of cutting equipment:

[0047] First, the spiral material tube curled into a cylindrical shape is sleeved on the feeding positioning plate 33, and then the end portion is pulled out and passed through the through hole 3221 of the feeding tube 322 to the gap between the two pressing wheels 312. At this time, the two pressing wheels 312 just abut against the spiral material tube, and the bent rod 531 on the feeding rod 53 is partially penetrated in the spiral material tube. After starting the machine, the two pressing wheels 312 run and the spiral material tube is pressed and moves forward under the friction of the pressing wheels 312. The first cutting blade 41 divides the spiral material tube into a plurality of workpieces to be processed and processes openings on the workpieces to be processed. The workpieces to be processed are pressed on the pressing wheels 312. Driven by the positioning groove 3121 of 12, they are pushed onto the feeding rod 53 one by one, and the coolant in the oil injection pipe 55 cools the workpiece to be processed. The workpiece to be processed runs downward along the feeding rod 53 to the slot 513 surrounded by the two pressing blocks 511 and is laterally fixed by the clamping assembly 51. At this time, the workpiece to be processed is arranged horizontally, and the second cutting mechanism 60 cuts the workpiece to be processed in the slot 513 to form an opening, and then the two third driving mechanisms 512 respectively drive the two pressing blocks 511 to loosen, and the processed fixing ring 111 is guided out of the machine along the receiving rod 70.

[0048] In summary, the cutting equipment of the present invention has a simple structure and realizes highly automated production, which can not only save manpower but also ensure the quality of cutting, and the error reaches the required dimensional effect. It is simple and safe to operate and has high production efficiency.
