Problems solved by technology

The defect of this forming method is that after the sheet is bent into an arc shape, it still has great flexibility because the two ends are not connected. During the transfer process, a slight shaking can deform it, so it cannot be processed Accurate positioning can not realize the automatic transfer of its processing process, which leads to the fact that the processing of such parts still needs to rely on a large number of manual operations at this stage

Embodiment 1

[0028] Such as figure 1 , 2 As shown, an inner cylinder wall forming machine includes a hemming mechanism 20, an overturning mechanism 30, a buckle seam mechanism 40 and a shaping mechanism 50, and the hemming mechanism 20 is used to bend the two ends of the plane sheet 1 into a V shaped bayonet and transport the plane sheet 1 to the turning mechanism 30, the turning mechanism 30 is used to turn the two ends of the plane sheet 1 by 180° respectively and make the two ends butt joint at the buckle seam mechanism 40, the buckle The sewing mechanism 40 is used to crimp and fix the two ends of the planar sheet 1 so that the sheet is connected into an annular tube 2 , and the shaping mechanism 50 is used to roll the annular tube 2 into a cylindrical shape. The invention integrates the rolling and seaming mechanism 40 of the cylindrical part, and adjusts the processing sequence, that is, first seams and then shaping, which solves the defect that the thin-walled parts are not suitabl...

Embodiment 2

[0040] A tube forming method using the above forming machine, comprising the steps of:

[0041] Step 1: blanking, cutting the metal strip into a rectangular flat sheet 1;

[0042] Step 2: embossing, punching the concave-convex structure and mounting holes on the flat sheet 1 according to the design requirements;

[0043] Step 3: Folding, conveying the flat sheet 1 to the folding mechanism 20, and using the folding mechanism 20 to bend the two ends of the flat sheet 1 into a V-shaped bayonet;

[0044] Step 4: Overturning, conveying the flat sheet 1 after flanging to the overturning mechanism 30, using the overturning mechanism 30 to turn over the two ends of the flat sheet 1 by 180°, and transferring the V-shaped bayonets at the two ends to the buckle seam mechanism 40 buckle at;

[0045] Step 5: buckle the seam, use the buckle seam mechanism 40 to rivet the fastening area of ​​the V-shaped bayonet, so that the two ends of the flat sheet 1 are fixed to form the annular tube 2...

Abstract

The invention belongs to the technical field of assembling and manufacturing, and particularly relates to an inner cylinder wall forming machine. The inner cylinder wall forming machine comprises an edge folding mechanism, an overturning mechanism, a seam buckling mechanism and a shaping mechanism; the edge folding mechanism is used for bending the two ends of a planar sheet into V-shaped bayonetsand conveying the planar sheet to the overturning mechanism; the overturning mechanism is used for overturning the two ends of the planar sheet by 180 degrees and enabling the two ends to be in buttjoint at the seam buckling mechanism; the seam buckling mechanism is used for pressing and fixing the two ends of the planar sheet to enable the sheet to be connected into an annular cylinder; and theshaping mechanism is used for rolling the annular cylinder into a cylindrical shape. According to the inner cylinder wall forming machine, the rolling and seam buckling mechanisms of the cylindricalpart are integrated, the machining sequence is adjusted, that is, seam buckling is conducted firstly and then shaping is conducted, the defect that the thin-wall part is not suitable for being conveyed after being rolled is overcome, automatic forming of the thin-wall cylindrical part is achieved, the machining process is simplified, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of assembly and manufacturing, and in particular relates to an inner cylinder wall forming machine. Background technique [0002] Thin-walled cylindrical parts such as the inner wall of the washing machine are generally processed in the process of bending first and then buckling, that is, the flat sheet is first rolled out to a certain arc, and then the two ends of the flat sheet are riveted. Press into one. The defect of this forming method is that after the sheet is bent into an arc shape, it still has great flexibility because the two ends are not connected. During the transfer process, a slight shaking can deform it, so it cannot be processed Without precise positioning, it is impossible to realize the automatic transfer of its processing process, which leads to the fact that the processing of such parts still needs to rely on a large number of manual operations at this stage.
