Problems solved by technology

During the processing of the part, the part is released from the mold by tapping from one end (see the schematic diagram of the fitting of the part and the mold figure 2 ), due to the close contact between the four sides of the part and the mold, the surface size of the part cannot be guaranteed, which increases the movement resistance of the guide rail and cannot meet the use requirements

Embodiment Construction

[0029] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings, but the required protection scope is not limited to the description;

[0030] Such as figure 1 and Figure 7 Shown is the final size drawing of the parts processed by the present invention and the schematic diagram of the position of each bending section. The thin-walled sheet metal part includes a first side, a second side and a third side connected in sequence, the length of the first side is greater than the third side, and the first side and the third side are perpendicular to the second side side, and the first side and the third side are located on the same side of the second side, the first S-shaped curved section 1 is arranged on the first side, and the second S-shaped curved section 4 is arranged on the third side, The first side is connected to the second side through the first right-angle bending section 2, the second side is connecte...

Abstract

The invention discloses a shaping mold and method of thin-wall sheet metal parts. The mold consists of three sets of sub molds including a first bending mold, a second bending mold and a third bendingmold (wherein each set of sub mold consists of a female mold and a male mold). When spare parts are processed, the three sets of sub molds are bent according to the sequence of the mold 1, the mold 2and the mold 3, and the bending positions are shown as the figure 3. The specific processing technology of the spare parts comprises the steps of performing blanking, performing bending for the firsttime,...performing bending for the second time,...and performing bending. The mold disclosed by the invention is simple to operate, the profile size of the spare parts can be guaranteed, the labor intensity of workers can be reduced, and the production efficiency of the spare parts can be improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to sheet metal forming of a "ji"-shaped thin-walled part. Background technique [0002] "Ji"-shaped guide rail groove (for the structural diagram of the parts, see figure 1 ) The material is 0Cr17Ni7Al, the thickness of the material is t1.0, and the length of the groove of the part is L=618.5 +0.5 mm. At present, the molding process used for this type of parts is: after two extrusion and bending moldings, the parts are separated from the molding die; blanking-initial bending...-bending-...knocking repair-correction. During the processing of the part, the part is released from the mold by tapping from one end (see the schematic diagram of the fitting of the part and the mold figure 2 ), due to the close contact between the four sides of the part and the mold, the surface size of the part cannot be guaranteed, which increases the movement resistance of the guide ra...
