Problems solved by technology

The Chinese patent with the application number 200320100608.9 provides a method for standing seaming of metal roof panels. Although it overcomes the defects of complicated operation and easy damage to metal roof panels in the traditional lock seam method, the inelastic deformation formed by it The lock seam is only 360°+90°+35°, and the wind force it can resist is not very strong, and it cannot resist the wind force in severe strong wind areas or typhoon-prone areas

Embodiment 1

[0028] Such as Figure 1-Figure 3 As shown, a metal roof panel lock seam method comprises the following steps:

[0029] (1) Set the 90° angle of the metal roof panel to be locked as the first angle 1; bend the lateral side of the first angle 1 inward to form an angle of 110° and set it as the second angle 2; set the second angle 2 The longitudinal edge of the second angle 2 is bent inwardly to form an angle of 30° to position the third angle 3, and the third angle 3 is continuously bent inwardly through two processes. The first process bends the third angle 3 to 20°, and the second process bends the third angle 3 to the inside. The angle bent in the first process is then bent to 0° to obtain the third angle 3 of 0°; this step (1) is completed on the lockstitch folding machine invented by our company.

[0030] (2) Continue to bend the second angle 2 of the part to be seamed obtained in step (1) through four processes, the first process bends to 86°, and the second process bend...

Embodiment 2

[0034] Such as Figure 1-Figure 3 As shown, a metal roof panel lock seam method comprises the following steps:

[0035] (1) Set the 90° angle of the metal roof panel to be locked as the first angle 1; bend the lateral side of the first angle 1 to the inside to form an angle of 110° and set it as the second angle 2; the second The longitudinal side of the corner 2 is bent inward through three bending processes to form the third corner 3, and the longitudinal side of the second corner 2 is bent inward to form an angle of 30° to position the third corner 3, and the third corner 3 is passed through two processes Continue to bend inwardly, the first process bends the third angle 3 to 15°, and the second process bends the angle bent in the first process to 3° to obtain the third angle 3 of 3°; this step (1 ) is completed on the lockstitch folding machine invented by our company.

[0036] (2) Continue to bend the second angle 2 of the part to be seamed obtained in step (1) through ...

Embodiment 3

[0040] Such as Figure 1-Figure 3 As shown, a metal roof panel lock seam method comprises the following steps:

[0041] (1) Set the 90° angle of the metal roof panel to be locked as the first angle 1; bend the lateral side of the first angle 1 to the inside to form an angle of 110° and set it as the second angle 2; set the second angle 2 The longitudinal side of the second angle 2 is bent inwardly to form an angle of 30° to position the third angle 3, and the third angle 3 is continuously bent inwardly through two processes. The first process bends the third angle 3 to 25°, and the second process bends the third angle 3 to the inside. The angle bent in the first process is then bent to 5° to obtain a third angle 3 of 5°; this step (1) is completed on the lockstitch folding machine invented by our company.

[0042](2) Continue to bend the second angle 2 of the part to be seamed obtained in step (1) through four processes, the first process bends to 89°, and the second process ...

Abstract

The invention relates to an operating method in the field of machinery, in particular to a metal roof panel whipstitching method. The metal roof panel whipstitching method comprises the following steps of: (1) setting an angle of 90 degrees in a part to be whipstitched of a metal roof panel as a first angle, inwards bending a transverse edge of the first angle to be a second angle of 110 degrees, and bending a longitudinal edge of the second angle to form a third angle of 0 to 5 degrees; (2) continuously bending the second angle of the part to be whipstitched to form an angle of 0 to 5 degrees; and (3) continuously bending the first angle of the part to be whipstitched obtained in step (2) to form an angle of 0 to 5 degrees. The metal roof panel whipstitching method is easy to operate and control and good in whipstitching effect.

Description

technical field [0001] The invention relates to an operation method in the field of machinery, in particular to a lock seam method for metal roof panels. Background technique [0002] At present, metal roof panels have been widely used on the roof of factory buildings. When using them, the male ribs, female ribs and brackets of the metal roof panels need to be installed first, and then the metal roof panels are locked and seamed. [0003] The locking seam of metal roof panels is mainly to lock the joints between the roof forming panels tightly according to different rolling combinations, so that the roof is tightly sealed and the structure is strengthened, so as to prevent water leakage and strengthen the overall structure and other effects. After the HV486 metal roof panel was launched on the market, it was favored by consumers because of its high cost performance. However, there is no good lock seam method for this metal roof panel on the market at present. The Chinese p...
