Description
Technical field
It the utility model is related to the manufacture of epoxy cast transformer, and in particular to the frock of Yi Zhong order molded coil internal models.
Background technology
Epoxy cast transformer coil after vacuum pouring and solidification, it is necessary to slough whole casting molds, wherein, in cast
The knockout course of mould is complex and difficult.
In China, since more than 40 years of epoxy cast transformer development, the structure and releasing process of pouring into a mould internal model are also sent out
Give birth to and changed several times.Originally, high-tension coil is cast, and low-voltage coil is not poured into a mould, and the demoulding is also just not present in low-voltage coil
Problem.Later, high and low pressure coil was all cast, release problems all be present.And high-tension coil experienced the thickness with filler absolutely
Edge cast, the cast of packless thin insulating and the thin insulating with filler pour into a mould three developing stage, and it is poured into a mould internal model and experienced two
Secondary big change.It is initially slab edge rolling, splicing welding joint, lathe process into tapered complete internal model structure（It is hereinafter referred to as thick
Harden structure）.Sheet curling, drilling flanging are developed into later, add rubber strip sealing, the docking internal model structure of bolt and nut fastening
（Hereinafter referred to as thin-slab structure）, also have and the internal model of thin-slab structure made the structure with taper.Two kinds of internal model structures are abroad
Cast transformer development in, and the such process of experience.
Cast internal model for thick plate structure, it is the technique that power or jack extrusion are hit by impact during the demoulding, completes the demoulding
Technique, it is difficult not only to manufacture thick plate structure internal model, and the technique used is also complex and benzene weight.The structure and the own quilt of technique
Eliminate.
Cast internal model for thin-slab structure, several nuts, the spiral shell of fit sealing rubber strip are dismantled during the demoulding one by one
Bolt, or fixture, operated in the less space of internal coil diameter, and very very difficult, and molded coil come out of the stove after also have tens
The temperature of degree, operator is soaked with sweat, and labor intensity is big.Meanwhile after having taken off mould, re-replace and install again caulking gum
Bar, to be used when coiling next time.This tears a dress sealing rubber strip open, when consuming most stripper, influences again most
Latter treat form removal coil because temperature declines it is excessive and caused by form removal it is difficult.
Therefore, the releasing process of epoxy cast transformer coil improves, and particularly the releasing process of internal model improves, and is one
Individual problem.
The content of the invention
The purpose of this utility model is to realize that Yi Xing order goes out to pour into a mould the technique of internal model, cancels one and tear a dress caulking gum open
The process of bar, and accomplish that sealing rubber strip may be reused.
One of technical solutions of the utility model：
The frock of Yi Zhong order molded coil internal models, frock are included by base, concrete foundation, channel-section steel folder, stretching screw, drawing
Bar, balancing pole and flat steel bar, base, which is fixed in concrete foundation, forms immobilizing foundation, by symmetrically setting between channel-section steel folder and base
The stretching screw more than two pieces put connects to form molded coil fixing device；The flat steel bar of flat steel bar and fit sealing rubber strip
It is connected by least two pull bars with balancing pole and forms Nei Mo order and go out device, hanging of being connected with power set is provided with above balancing pole
Hook.
Further, the horizontal slotted hole of installation stretching screw is provided with base relative to the positive side diametric(al) of coil two.
Further, described pull bar upper end is annulus, and annulus is enclosed on energy level on balancing pole and is slidably connected, and pull bar lower end is
Hook, the hook of pull bar lower end hook the flat steel bar of flat steel bar and fit sealing rubber strip respectively, and flat steel bar is welded in internal model.
Further, two pieces channel-section steel folder is connected by symmetrically arranged four stretching screws.
Further, the length direction elongated central line of described pull bar should be with flat steel bar and the band steel of fit sealing rubber strip
The length direction center line of bar overlaps.
The two of technical solutions of the utility model：
Its application method of the frock of Yi Zhong order molded coil internal models, floor installation are having on concrete foundation, molded coil
It is placed on base, two pieces channel-section steel folder is pressed on molded coil, and abuts internal model, with stretching screw molded coil and groove
Steel clamp part clamps, and removes a fastening bolt spiral shell with the height such as flat steel bar on the flat steel bar of fit sealing rubber strip in internal model
Mother, hang up pull bar and balancing pole, with bridge type vehicle-driving lift by crane balancing pole, i.e., can order go out internal model.
Further, the position of flat steel bar internal model interior sealing rubber strip symmetric position, and flat steel bar vertical center line with
The vertical center line of sealing rubber strip is parallel and symmetrical, and the length of flat steel bar is about 1/3rd of whole pour mass height, flat
There is the hole that pull bar can be allowed to tangle on steel bar, the height such as the hole on flat steel bar and hole of one of fit sealing rubber strip.
Further, order goes out internal model point three steps operation Shang , during driving lifting；
The first step allows driving hook that pull bar and balancing pole in the position that just contact internal model stress, and are adjusted each
Stress point whether centring line；
Second step point makes a movement the switch that controls upwards of driving, internal model is loosened upwards, i.e. the de- dynamic teeming line of internal model
Circle；
Internal model, is pulled out molded coil by the switch that the 3rd step-length is controlled upwards by driving upwards, complete into order mold process.
This Shi should be carried out rapidly with Xin Xing order mold technique when molded coil is in hot, when molded coil temperature is down to ring
During the temperature of border, due to the contraction of epoxy resin, demoulding difficulty can increase, or even draw bad internal model, now just need to by out-of-date methods form removal,
Remove sealing rubber strip.
The internal model of pull-out somewhat arranges, you can further around next coil, without a mistake for tearing a dress sealing rubber strip open
Journey.
This Shi realizes Yi Xing order with Xin Xing order die craft equipments and application method and goes out to pour into a mould the technique of internal model, eliminates cast
Internal model one tears the process of a dress sealing rubber strip open, and sealing rubber strip may be reused, and greatly saves and consumes man-hour, saves material
Material, mitigate labor strength, product quality is ensure that, suitable for mold technique in the order of all high and low pressure molded coils.
