Problems solved by technology

[0002] At present, the top frame and bottom frame used for low-voltage cabinets in China generally connect the sides of the frame together to form a whole frame by means of assembly or welding. There is stress, so it is easy to deform under the action of external force in the later stage, which affects the mechanical and electrical properties of the switchgear and brings great difficulty to the normal use of the switchgear

Embodiment Construction

[0012] An assembled frame is used for the top frame and bottom frame of the electric control cabinet. The frame is mainly formed by cutting, stamping and bending galvanized steel sheets at one time, which saves the process of assembly or welding.

[0013] The process flow of the present invention is: 1) first place the galvanized steel plate on the shearing machine, and cut it into a square steel plate of a specified size by the shearing machine; 2) place the cut square steel plate on the punching machine, press the corresponding top frame or bottom 3) Fold the edges on the folding bed, each edge of the frame 1 is provided with a secondary fold 1' formed by bending twice at right angles, the frame is the main part of the switch cabinet body, through The assembled frame produced by the present invention can make the diagonal size of the top frame and the bottom frame of the switch cabinet have no deviation. Because it is formed at one time, there is no stress between the frames,...

Abstract

An assembling frame used as top frame or bottom frame is made up of galvanized steel plate through the integration of shearing, punch and crimping. It can be used for cabinet.

Description

technical field [0001] The invention relates to an assembled frame, which belongs to the technical field of machinery. Background technique [0002] At present, the top frame and bottom frame used for low-voltage cabinets in China generally connect the sides of the frame together to form a whole frame by means of assembly or welding. There is stress, so it is easy to deform under the action of external force in the later stage, which affects the mechanical and electrical properties of the switchgear and brings great difficulty to the normal use of the switchgear. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art and provides an assembled frame with precise dimensions and no deformation. [0004] In order to solve the above problems, the present invention adopts the following technical solutions: an assembled frame, which is formed by cutting, punching and bending gal...
