Description

Technical Field

[0001] The utility model belongs to the technical field of production of distribution boxes and relates to a bending and blanking component of a distribution box body. Background Art

[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection.

[0003] The massive parameters on the distribution box data generally constitute the low-voltage forest. According to the electrical wiring, it is required to assemble the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches.

[0004] At present, in the production process of the distribution box body, one of the steps is to bend the long strip of box plate three times and cut it once, so that the box plate presents a square shape, and then weld the two open ends of the square shape together to form a ring-shaped box body. When bending, a pressing plate descends to press the box plate against the base, and then a flap flips up 90° to bend the box plate; the first bending makes the box plate present an L shape, the second bending makes the bent part of the box plate present a U shape, and the third bending makes the bent part of the box plate present a square shape (the end is free), and finally the cutting knife at the bottom rises (the pressing plate also presses the box plate during cutting), and the cutting knife and the pressing plate form a shearing action and cut the box plate; after cutting, the pressing plate rises slightly, and the worker drives the free end of the box plate upward and expands the opening end of the box plate, and then moves the box plate so that the pressing plate passes through the opening of the box plate, and then separates the box plate from the pressing plate. However, in practice, it is found that since the box panels have certain rigidity and elasticity, and the ends of the box panels are relatively sharp and prone to burrs, manually opening the bent box panels is not only laborious, but also risky and has poor operating results.
