Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing and non-limiting embodiment:

[0016] as attached Figure 1-3 Shown is a cardboard manual hemming device, which includes a base 7 , a limit beam 4 , a fixed beam 5 , and an overturning beam 6 . The left and right sides of the base 7 are respectively provided with brackets 1 . The limiting beam 4 and the fixed beam 5 are arranged between the two brackets 1 , and the limiting beam 4 and the fixed beam 5 are arranged correspondingly up and down and are respectively fixedly connected with the brackets 1 on both sides. There is a gap between the limit beam 4 and the fixed beam 5 to allow the cardboard to pass through. An overturning beam 6 is arranged in front of the fixed beam 5 , and the two ends of the overturning beam 6 are respectively connected with the brackets 1 on both sides of the base 7 through the rotating shaft 2 , and the overturning beam 6 can rotate around the rot...

Abstract

The invention discloses a device for bending edges of a paperboard manually, which is mainly used for bending and forming an insulating paperboard used in a transformer and belongs to the technical field of transformer manufacturing. The device comprises a base (7), wherein the left side and the right side of the base (7) are provided with brackets (1); a limiting beam (4) and a fixing beam (5) are arranged between two brackets (1); the limiting beam (4) and the fixing beam (5) are arranged opposite to each other vertically and are fixedly connected with the brackets (1) on the two sides of the base; a space through which the paperboard can pass is reserved between the limiting beam (4) and the fixing beam (5); a rotatable turning beam (6) of which two ends are connected with the brackets (1) on the two sides of the base is arranged in front of the fixing beam (5); the turning beam (6) is provided with handles (8); and the rear part of the fixing beam (5) is provided with a positioning mechanism. The device for bending the edges of the paperboard manually has a simple structure, can bend and form paperboards conveniently, is convenient to operate, has high processing efficiency, high bending quality and low bending rebound, and does not damage or contaminate the insulation of the paperboards.

Description

technical field [0001] The invention relates to a cardboard manual edge folding device, which is mainly used for bending and forming insulating cardboard in a transformer, and belongs to the technical field of transformer manufacturing. Background technique [0002] Among the solid insulation parts of oil-immersed power transformers, a considerable part of the insulation parts is bent into an "L" shape or "∏" shape by insulating cardboard, such as: pad insulation, upper beam insulation, side beam insulation, lead wire protection, etc. There are many types and specifications of slots, insulating bent plates, magnetic shielding insulating slots, etc., and the quantity is also large. For example, there are about a hundred pieces of magnetic shielding insulating paper slots in each 220kV transformer, and thousands of insulating bent plates. Usually, the above-mentioned insulating parts are generally processed by hand, that is, clamping with two pliers after wet water, and then b...
