Description
Technical field
The utility model relates to the machinery using in a kind of transformer manufacture technology, is specifically related to a kind of apparatus for bending of transformer insulated cardboard.
Background technology
In transformer magnetic screen manufacturing process, need a large amount of edges be bent into L shaped insulating board, the thickness of this class insulating board is probably 1 millimeter, and length surpasses 1 meter, and edge folds is divided and is often only had several millimeters to tens millimeters.At present, it mainly adopts artisan craftsmanship to carry out bending, after the wet water of insulating board, with two bench vices, clamps, then uses wooden mallet beatening, and its complex operation, labour intensity is large, efficiency is low, and easy resilience after insulating board bending affects the insulation effect of transformer.
Summary of the invention
The purpose of this utility model is to provide a kind of apparatus for bending of transformer insulated cardboard, to improve bending efficiency, the reduction labour intensity of insulating board, avoids the resilience after insulating board bending simultaneously.
The apparatus for bending of transformer insulated cardboard described in the utility model, by operating desk, cardboard hold assembly and cardboard bending component, formed, described cardboard hold assembly comprises cushion block, bottom plate, filler strip and upper mounted plate, cushion block is positioned on operating desk, bottom plate is positioned on cushion block, filler strip is positioned on bottom plate, upper mounted plate be positioned on filler strip and vertical with bottom plate over against, upper mounted plate, bottom plate and cushion block are mounted by means of bolts on operating desk, make to be formed with between upper mounted plate and bottom plate the gap of clamping insulating board; Described cardboard bending component comprises rotatable support and movable pressing board, rotatable support is fixedly mounted on operating desk, and be positioned at a side of cushion block, movable pressing board is connected with rotatable support near one end of cushion block, one end away from cushion block is supported on operating desk and is welded with operating grip, the upper surface of movable pressing board and the upper surface flush of bottom plate, movable pressing board can relatively rotate the rotating shaft of support member along rotating near upper mounted plate direction.
Described cardboard bending component has two covers, lays respectively at the both sides of cardboard hold assembly, can carry out the bending of two insulating boards simultaneously, improves bending efficiency.
When bending operation, first insulating board is lain on movable pressing board, needed a side of bending to insert in the described gap that the support by filler strip of upper mounted plate and bottom plate forms, then by operating grip, upwards promote movable pressing board, movable pressing board rotates around the rotating shaft of rotatable support, bending insulating board, until movable pressing board is stopped by upper mounted plate and stops, insulating board is bent moulding just.The width that insulating board edge folds is divided can the distance to upper and lower fixing plate edge be realized by adjustment filler strip.
The utility model adopts operating desk, cardboard hold assembly and cardboard bending component to cooperatively interact, utilize lever principle to realize the bending of insulating board, its improved insulating board bending efficiency, reduced labour intensity, the actual bending angle of insulating board is greater than 90 °, thereby effectively reduced the resilience of insulating board, avoided affecting the insulation effect of transformer, guaranteed the product quality of transformer, and it is simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is working state schematic representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
The apparatus for bending of transformer insulated cardboard as shown in Figure 1, by operating desk 1, cardboard hold assembly and two cover cardboard bending components form, cardboard hold assembly comprises cushion block 4, bottom plate 5, upper mounted plate 7 and two filler strips 6, the thickness of every filler strip 6 is all 1.5 millimeters, cushion block 4 is positioned on operating desk 1, bottom plate 5 is positioned on cushion block 4, two filler strip 6 intervals are placed on bottom plate 5, upper mounted plate 7 be positioned on two filler strips 6 and vertical with bottom plate 5 over against, upper mounted plate 7, bottom plate 5 and cushion block 4 are fixedly mounted on operating desk 1 by bolt 9, make to be formed with between upper mounted plate 7 and bottom plate 5 gap of clamping insulating board 10.Every cover cardboard bending component all comprises rotatable support 2 and movable pressing board 3, two rotatable support 2 are all fixedly mounted on operating desk 1, and lay respectively at the both sides of cushion block 4, two movable pressing boards 3 all connect with corresponding rotatable support 2 near one end of cushion block 4, two movable pressing boards 3 are all supported on operating desk 1 and are welded with operating grip 8 away from one end of cushion block 4, the upper surface of two movable pressing boards 3 all with the upper surface flush of bottom plate 5, two movable pressing boards 3 all can rotate along close upper mounted plate 7 directions relative to the rotating shaft of corresponding rotatable support 2, two rotatable support 2 can guarantee that to the distance of upper mounted plate 7 two movable pressing boards 3 rotate 120 ° and by upper mounted plate 7, do not stopped around the rotating shaft of corresponding rotatable support 2.
As shown in Figure 2, when bending operation, first the insulating board of 1 millimeters thick 10 is lain on movable pressing board 3, need a side of bending to insert in the gap that the support by filler strip 6 of upper mounted plate 7 and bottom plate 5 forms insulating board 10, then by operating grip 8, upwards promote movable pressing board 3, movable pressing board 3 rotates around the rotating shaft of rotatable support 2, bending insulating board 10, until movable pressing board 3 is stopped by upper mounted plate 7 and stops, insulating board 10 is bent moulding just.The width that the edge folds of insulating board 10 is divided can be the in the situation that of loose bolts 9, by adjusting filler strip 6, to the distance at upper mounted plate 7, bottom plate 5 edges, realizes.
