[0039] The edge of the support side plate 3 is offset to coincide with the corner along the cutting groove 32 to form a bending area 31, and the bending area 31 is bent to form a plurality of mutually separated bending lugs 34.

[0040] The inner side of the support side plate 3 close to the bending area 31 is stamped to form a reinforcing rib 36.

[0041] One side edge of the support side plate 3 is arranged in a "Z" shape, and the corners of the edges contained in the side are all arranged with rounded corners.

[0042] It also includes a plurality of reinforcing members 10, which can be installed between the bending lugs 34 to reinforce the bending lugs 34.

[0043] The connecting piece 4 includes a plurality of connecting rods 41 and two connecting angle steels 42, and the connecting rods 41 and the connecting angle steels 42 are both installed between the two support side plates 3.

[0044] The two connecting angle steels 42 are installed between the two sides of the bottom of the two support side plates 3, and locally extend out of the two support side plates 3 to form reinforcing members 10, which not only connect the two support side plates 3, but also connect and reinforce the adjacent bending lugs 34 in the support side plate 3.

[0045] The setting of the cutting groove 32 can avoid the interference between the bending ears 34 at the straight edges of the support side plate 3, and the bending groove 33 is arranged at the edge angle of the rounded edge, the width of the bending ear 34 corresponding to the rounded area can be reduced, so that the bending ear 34 can be bent and formed, thereby enhancing the vertical support strength of the support side plate 3.

[0046] The detachable connection can be achieved by bolt connection.

[0047] Please refer to Figure 3 A conveyor head and tail frame production method for producing the conveyor head and tail frame 1 comprises the following steps:

[0048] S1, the top and bottom of the steel plate with a thickness not less than 4mm are arranged symmetrically along the origin to cutting end points, and a "Z" shaped division line 35 is arranged between the two cutting end points, and the rectangular plate is cut into equivalent support side plates 3 along the "Z" shaped division line 35;

[0049] S2, the bending area 31 with a width of 30mm to 60mm is formed by inwardly offsetting along the edge of the support side plate 3, the cutting groove 32 is arranged at the edge angle of the straight edge of the support side plate 3, and the two sides of the cutting groove 32 are respectively perpendicular to the corresponding two edges; the bending groove 33 is arranged at the edge angle of the rounded edge, the depth of the bending groove 33 is less than the length of the side of the cutting groove 32, and the rounded corner is R50 to R150mm;

[0053] The shape optimization of the support side plate 3 after stamping and shaping mainly includes the increase of the cross-sectional moment of inertia, the limited dispersion of stress of the stamping deformation structure, and during the stamping deformation process, the outer layer of the support side plate 3 is subjected to tension and the inner layer is subjected to pressure, and the strain gradient is increased. The strain gradient is inversely proportional to the bending radius, the smaller the curvature radius, the greater the strain gradient, and the higher the stress borne by the outer layer of fibers. On the other hand, during the stamping deformation process, the material undergoes plastic deformation, the dislocation density increases, and work hardening is formed, which indirectly improves the rigidity.
