 refer to Figure 1-Figure 8 , a metal profile forming device, including a pipe 1 for triangular pipe production, the pipe 1 is covered with an outer extruding mechanism 2, and the outer extruding mechanism 2 is used to flatten the side wall of the triangular pipe, and the The outer extruding mechanism 2 is a triangular shaft rolling structure, which includes a connecting block 201 and a roller 202. The inner extruding mechanism 3 is sleeved inside the pipe material 1, and the inner extruding mechanism 3 is used for triangular The corners of the tube are formed, and the inner extrusion mechanism 3 is a triangular wheel rolling structure, which includes a mounting seat 301 and an extrusion wheel 304;
 The device fully considers the cost of production equipment and the cost of learning the skills of operators. The inner extrusion mechanism 3 and the outer extrusion mechanism 2 can be used to shape the common stainless steel thin-walled round tubes to obtain triangu...
A metal profile forming method, applied to the above-mentioned device, said method comprising the following steps:
 S1. Prepare a stainless steel thin-walled round pipe as the raw material pipe 1, and use tooling to support one end of the pipe 1, so that the subsequent use of the inner extrusion mechanism 3 and the outer extrusion mechanism 2 can be used for spinning under the pull of the cable 4;
 S2. Pass the cable 4 connected to the shaping block 306 through the pipe material 1, pull the cable 4 so that the round end of the shaping block 306 is inserted into the pipe material 1, and continue to pull the cable 4 relative to the pipe material 1, so that the pipe material 1 is located in the inner extrusion The part in front of the movement direction of the mechanism 3 initially obtains an approximately triangular outline under the extrusion of the shaping block 306, and the inner extrusion mechanism 3 has not yet fully entered the pipe 1;
 S3. Ap...
 The difference from Example 1 is that when the requirements for the edge shape of the triangular tube are relatively low, only the outer extruding mechanism 2 can be used for the final rolling operation, and the obtained edge of the triangular tube will have obvious radians.
