Description
Technical field
This utility model relates to the manufacture of power transformer, the specifically manufacture of Long Circle dry-type transformer coil.
Background technology
In the transformator manufacturing identical capacity, the ferrum of Long Circle dry-type transformer and the consumption of copper significantly reduce, and reduce
Production cost, saves ample resources for society, has good development prospect.But, Long Circle coil in winding process by
In the rebound effect of cable self, make coil produce at the short of long round section and bigger extend out power, cause coil line part
Divide with radian.Use the coil straight line portion outside dimension after pouring technology cast not meet technology requirement, have impact on coil
Mechanically and electrically performance.
Utility model content
Utility model purpose: for problems of the prior art, the utility model discloses a kind of Long Circle coil
Casting mold, this mould, by adding the straight device of clamping at straight line portion, controls Long Circle coil straight line portion external diameter well
Size, improves the mechanical strength that coil is overall, is prevented from coil cracking to a certain extent.
Technical scheme: the utility model discloses a kind of Long Circle coil pouring mould, including upper head plate, interior mould, external mold,
Bottom plate, base, boss panel, upper pressure rack, longitudinal direction are strained screw mandrel and press from both sides straight device, level tension screw mandrel；Wherein bottom plate is solid
On base, interior mould bottom is fixed with bottom plate, base by bolt, and interior mould top is fixed with upper head plate；External mold is by upper
Longitudinal direction tension screw mandrel tension between pressure rack and base, is fixed on base bottom boss panel, and boss panel encloses height position online
Put place to be connected with upper head plate；Pressing from both sides that straight device is vertically symmetrical is arranged on straight line portion outside external mold, lower end is provided with screw, by fastening
Bolt is fixed on and is arranged between the fixed supported slab on base and external mold；Level tension screw mandrel is installed in upper end, is strained by level
Straight for symmetrically arranged folder device is strained by screw mandrel.The straight device of one or more pairs of folder can be set.
Level tension screw mandrel can be arranged on the straight device of folder by being arranged on the screw pressing from both sides straight device upper end or recess.
Press from both sides straight device and can make tabular, i.e. press from both sides straight plate.
Further, pressing from both sides straight device is channel-shaped, i.e. presss from both sides straight trough.Folder straight trough upper end is provided with reinforcing plate and can improve further
Pressing from both sides the mechanical strength of straight device, described reinforcing plate upper end has recess and is easily installed level tension screw mandrel.
Beneficial effect: compared with prior art, this utility model has the advantage that 1, by adding the straight device of clamping, energy
Enough good control coil straight line portion outside dimensions, the coil entirety preventing coil from causing because external diameter exceedes technology requirement becomes
Shape；2, press from both sides straight device upper end and have recess, press from both sides straight device by this recess by symmetrically arranged two and use level tension screw mandrel
Tension, can regulate the setting height(from bottom) of level tension screw mandrel, it is adaptable to the casting mold of differing heights；3, straight device is pressed from both sides by tight
Fixing bolt, level tension screw mandrel is installed fixing, it is simple to dismantles and installs；4, the folder straight trough of channel-shaped is effectively increased and presss from both sides straight device
Mechanical strength, presss from both sides straightforward energy more preferable；5, set up the straight device of folder and do not destroy the integrity of external mold, seepage will not be caused；6, folder is straight
Groove can use standard model channel-section steel to make, and processing technology is simple.

Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with this utility model.
Embodiment one:
As it is shown in figure 1, a kind of casting mold for Long Circle dry-type transformer coil, including upper head plate 1, interior mould 2, outer
Mould 3, bottom plate 4, base 5, boss panel 6, upper pressure rack 7, longitudinally tension screw mandrel 8, fixed supported slab 10, folder straight trough 14, level are drawn
Tight screw mandrel 11.
When mould is installed, bottom plate 4 uses screw to be fixed on base 5, interior mould 2 bottom by screw and bottom plate 4,
Base 5 is fixed, and interior mould 2 top is fixed with upper head plate 1 by screw；Straining screw mandrel by the longitudinal direction between upper pressure rack and base will outward
Mould 3 is strained, and boss panel 6 is connected by securing member with upper head plate at coil height and position；Screw is used bottom boss panel
It is fixed on base.
In the present embodiment, a pair folder straight trough 14 is vertically symmetrical is arranged on the midpoint of straight line portion outside external mold, and folder is straight
Groove lower end is provided with screw, is fixed on by fastening bolt 9 and is arranged between the fixed supported slab on base and external mold, the length of folder straight trough
Spending longer more than 100mm than mold height, upper end has recess 12, is drawn by symmetrically arranged folder straight trough by level tension screw mandrel
Tightly.Fixed supported slab uses welding or is fixed on base with base cast-in-block mode.
The schematic diagram of the fixed supported slab 10 that Fig. 3 is disposed on base, can use welding or with base cast-in-block
Mode is fixed on base.
For the mechanical strength of reinforcement clamp straight trough, adding reinforcing plate 15 on folder straight trough top, recess is opened on reinforcing plate top, as
Shown in Fig. 4.Fig. 5 is the increase in the top view of the folder straight trough of reinforcing plate.
The size of folder straight trough can determine according to the size of mould, it would however also be possible to employ the channel-section steel of standard model, such as 5# channel-section steel
Make.
Embodiment two:
The present embodiment with the difference of embodiment one is: pressing from both sides straight device is tabular, i.e. presss from both sides straight plate 13, as shown in Figure 6.With channel-shaped
The straight device of folder compare, the processing technology pressing from both sides straight plate is simpler, can make the straight plate of folder of different in width according to actual needs.
