The multi-sectional type automatic mold for one-step cutting and rolling of stainless steel profile according to claim 8, wherein: one side of the deformation positioning space (206) close to the positioning plate (207) is provided with a guide inclined plane (209), one end of the guide inclined plane (209) is communicated with the bottom surface of the deformation positioning space (206), and the other end of the guide inclined plane is communicated with the bottom surface of the main space (205).
10. A method of stamping, comprising the steps of:
the method comprises the following steps: conveying the section bar (1100) to the position below a first stripper plate (300), moving an upper template (100) downwards, and punching for the first time by using the first stripper plate (300);
step two: the section bar (1100) is continuously conveyed along the guide slide baffle (202) and is abutted against the positioning plate (207), and the circular hole formed by punching for the first time in the first step is used for positioning;
step three: the upper template (100) moves downwards, a first stripper plate (300) is firstly pressed on the section bar (1100), and a first punching is carried out on the second section of the section bar;
step four: continuously moving the upper template (100) downwards to enable the second stripper plate (400) to be pressed on the first section of section bar for secondary punching, forming a groove on the first section of section bar by matching the forming package insert (102) with the deformation positioning space (206), forming a punched hole on the groove by the extrusion needle (103), and at the moment, cutting off the tool rest (208) to enable the first section of section bar and the second section of section bar to be separated from each other;
step five: the upper template (100) moves upwards, and a second gap (800) is restored between the second stripper plate (400) and the upper template (100) under the action of the second elastic piece (700), so that the end part of the extrusion needle (103) is separated from the first section of the section bar;
step six: pushing the second section of section bar to indirectly push the first section of section bar, sliding the first section of section bar out of the extrusion space (201) under the action of the guide inclined plane (209), and enabling the second section of section bar to replace the first section of section bar to enter the extrusion space (201);
step seven: and repeating the operations from the second step to the sixth step to realize continuous production.
