The round tube 400 passes through the round tube flattening die 20 under the traction of the traction mechanism, the round tube 400 is extruded into a rectangular tube 700, the rectangular tube 700 is conveyed to the clamping mechanism 600 and clamped by the clamping mechanism 600, then the rectangular tube 700 is cut off by the rectangular tube cutting mechanism 500, and the finished rectangular tube 700 is pushed against the rectangular tube collecting mechanism 800 when the next rectangular tube 700 is conveyed to the clamping mechanism 600, so that the automatic processing is realized, and the working efficiency is high.

Referring to fig. 2, 3 and 5, the round tube flattening mold 20 includes a mold main body 100, a molding core 200 and a molding core 300. The die body 100 is dug with through holes penetrating through both ends of the die body 100, and the through holes are arranged along the axis of the die body 100.

The molding die core 200 is provided with a rectangular channel 201 penetrating through two ends of the molding die core, the rectangular channel is coaxial with the through hole, and specifically, the cross section of the rectangular channel 201 is rectangular. One end of the rectangular channel 201 close to the molded output end is a molded end 202, and the shape of the molded end 202 is consistent with the outline shape of a common USB shell in the market. The other end of the rectangular channel 201, which is far away from the molding output end, is gradually expanded outwards to form a horn-shaped input end 203, and a first convex arc part 204 is smoothly transited between the molding end 202 and the input end 203.

Referring to fig. 2, 4 and 6, the mold core 300 includes a core rod 310. One end of the core bar 310 is narrowed to form a rectangular molding part 320, the core bar 310 and the rectangular molding part 320 are both rectangular corresponding to the molding end 202, and a concave second arc part 330 is smoothly transited between the core bar 310 and the rectangular molding part 320. The rectangular forming portion 320 is coaxially received in the forming end 202, so that equidistant gaps are formed between the rectangular forming portion 320 and the forming end 202, and between the second arc portion 330 and the first arc portion 204, and the gaps are spaces for receiving pipes to pass through smoothly. The circular tube material passes through the gap between the molding die core 200 and the molding die core 300 under the traction of the external force of the equipment, and the circular tube 400 is extruded into a rectangular tube 700 with compact structure.

Because the other end of the rectangular channel 201 is gradually expanded outwards to form a horn-shaped input end 203, the circular tube is gradually deformed under the guidance of the structure of the horn-shaped input end 203 and smoothly enters the forming end 202.
