Description
Technical field
The present invention relates to a kind of transformer accessory, more particularly to a kind of manufacturing technology field of iron core folder.
Background technology
Existing iron core folder includes high pressure upper clamping piece, high pressure lower clamping piece, low pressure upper clamping piece, low pressure lower clamping piece respectively,
Three pull bars are set between high pressure upper clamping piece, high pressure lower clamping piece, three are set between the low pressure upper clamping piece, low pressure lower clamping piece
Pull bar, high and low pressure upper clamping piece are oppositely arranged, and high and low pressure lower clamping piece is oppositely arranged, and the both ends of each pull bar pass through bolt, spiral shell respectively
Mother is fixed on the inner side of the upper and lower folder of high pressure of the homonymy；The upper and lower folder of high and low pressure of existing iron core folder is respectively
Section groove steel is made, and because channel-section steel is mostly standard specification, also needs to reprocess for making iron core folder so that production technology becomes
Cumbersome, low production efficiency is obtained, then has channel-section steel weight big so that whole iron core folder also accordingly increases；There are pull bar and high and low pressure again
Connected mode between upper and lower folder so that after iron core installation, gap be present between iron core and the upper and lower folder of high and low pressure, no
It is enough stable.
The content of the invention
In order to overcome above-mentioned technical problem, the present invention provides a kind of dry variant iron core folder.
The present invention includes four cell bodies formed by steel plate bending, and four cell bodies are respectively as high pressure upper clamping piece, height
Folder, low pressure upper clamping piece, low pressure lower clamping piece are depressed, the bottom of each cell body sets three connection grooves, the connection respectively
Groove is separately positioned on the angle between the cell body bottom surface and side, and a port for connecting groove is arranged on described
In cell body side wall, three arm-ties are set respectively between the cell body corresponding two-by-two, the both ends of the arm-tie are fitted together to respectively
In the connection groove of two corresponding cell bodies, the height of the connection groove is not more than the thickness of the arm-tie, institute
The outside bottom surface that arm-tie is stated with the cell body flushes；Multiple connection through holes are set on the bottom surface of the cell body.
The present invention corresponds to arrangement, connected between the upper and lower folder of high pressure of homonymy in use, four cell bodies are applied in combination two-by-two
Three arm-ties are connect, each arm-tie is respectively embedded into cell body, and each arm-tie does not protrude cell body surface, and is flushed with cell body surface, so exists
After iron core clamp is attached between folder, iron core with as high pressure upper clamping piece, high pressure lower clamping piece, low pressure upper clamping piece, low pressure lower clamping piece
It is very close to each other between cell body so as to be connected between iron core and folder more firm；Further, folder cell body is taken by whole plate punching, then
Bending is formed again, and its processing efficiency improves, and it is light that the cell body that bending is formed processes the cell body weight to be formed than existing product channel-section steel,
Without following process, production efficiency is improved, meanwhile, avoid the spillage of material in process.
Connection groove of the present invention is arranged on setting wire casing, the wire casing at the port in the cell body side wall and is arranged on
In the cell body side wall, the wire casing is arranged between arm-tie and the cell body side wall；Set wire casing is convenient to thread, beneficial to peace
Dress.
Connection groove of the present invention is dovetail groove, and the both ends of the arm-tie are arranged respectively to corresponding with the dovetail groove
Dove-tail form.It is arranged to given shape to be easy to arm-tie and connect the Qian He of groove on cell body, connects more stable.
Connection groove of the present invention can also be round groove, square groove, and the shape at arm-tie both ends connects respectively at accordingly
The shape for connecting groove is corresponding.
One Sidewall Height of cell body of the present invention is less than the half of another side wall, the shorter cell body side
Wall is the remote one side of upper and lower mutually corresponding cell body；Three breach are set in the higher cell body side wall.Idle side wall
Setting is shorter, can greatly mitigate the weight of cell body, equally, higher side wall is set into breach, can also mitigate cell body weight,
Whole iron core folder weight also mitigates significantly after assembling.
The present invention as high pressure upper clamping piece, low pressure upper clamping piece the cell body on hole for hoist is set.
