Abstract
The utility model discloses a kind of bend pipe accessory of square tube, including pad, front and the square tube bending part inner cavity of the pad coincide.Pad front fills in square tube inner cavity bending part and realizes support, ensuring square tube, tube wall will not be to inner cavity extensional in bending, and to keep the lumen size of bending place consistent, the stroke that cooling medium stream is crossed is consistent, and then ensure the safety of cooling effect and transformer station high-voltage side bus；Under the premise of identical tube chamber, overall dimensions can be reduced compared with the structure of more square tubes splicing, save space and material；It need not weld, workload is greatly reduced, improve process velocity.
Description
Technical field
The utility model is related to bend pipe rapidly fields, and in particular to a kind of bend pipe accessory of square tube.
Background technology
Copper tube in intermediate-frequency transformer secondary coil assemblies, technological requirement shape are U-shaped, and section is flat rectangular
Shape, is limited to the elongation and workpiece shapes of red copper, and bending after the prior art is heated with single square tube can not be supported because of inner cavity
And there is uncontrollable deformation, the square tube intracavity section as cooling water channel changes, and cooling medium stream speed can be made inconsistent,
Cooling effect is variant, and be easy to causeing transformer, local temperature is excessively high at work, and there are security risks；Therefore prior art is
As shown in figure 3, to spell neat welding fabrication after the size bending of gradual change after several red copper square tubes are heated respectively；First, in order to cold
But effect meets the requirements, it is necessary to ensure that the cross-sectional area of cooling water channel, and the outer wall that adjacent two square tubes are close to can increase red copper
The size of pipe entirety, occupies larger space, and material cost is higher；Secondly, size difference of the every square tube in bending part
The stroke that cooling medium stream is crossed can be caused different, cooling effect is variant, and temperature distribution is non-uniform when secondary coil being made to run, and holds
It is also easy to produce security risk；Again, welding job amount is big, and time-consuming for processing.
Invention content
The technical problem to be solved by the present invention is to provide a kind of bend pipe accessories of square tube, can solve existing copper tube
Using neat welding is spelled after more square tube gradual change bendings, cause occupied space big, of high cost, cooling effect is variant, welding job
The problem of amount is big, time-consuming.
The utility model is achieved through the following technical solutions：
A kind of bend pipe accessory of square tube, including pad, front and the square tube bending part inner cavity of the pad coincide.
The further scheme of the utility model is that the rear end of the pad is connected with connecting rod, and pad has both been facilitated to be inserted into, take
Go out, the structure outside tube chamber is extended to compared to pad rear end, weight can be mitigated, it is easy to operation, moreover it is possible to reduce cost.
The further scheme of the utility model is that the pad with link detachable is connect, by replacing different sizes
Pad can be adapted for the bendings of different size square tubes, further reduce the cost.
The further scheme of the utility model is to be connected with nozzle postive stop baffle on the connecting rod, prevent in process
Pad, which slides into tube chamber depths, influences machining accuracy.
The further scheme of the utility model is that the nozzle postive stop baffle is connected to connecting rod by threads turn, more
It is easy to control the insertion depth of pad, makes machining accuracy higher, the waste of material of square tube is reduced, further reduces the cost.
The further scheme of the utility model is to be also equipped with tube chamber supporting mechanism on the nozzle postive stop baffle, to lining
Block realizes further positioning, reduces the possibility that pad skids off tube chamber, further increases machining accuracy.
The further scheme of the utility model is that the tube chamber supporting mechanism includes being connected to the nozzle postive stop baffle back side
Guide sleeve, is slidably connected to the sliding block of guide sleeve, and more rear end thereofs are connected to the supporting rod of sliding block, the guide sleeve and cunning
It is provided with detent mechanism between block, multiple pilot holes, described more supporting rod front ends are provided on the nozzle postive stop baffle
Pass through pilot hole obliquely outward correspondingly；It is easy to operate using the structure of similar umbrella rib.
The utility model compared with prior art the advantages of be：
Pad front fills in square tube inner cavity bending part and realizes support, it is ensured that square tube tube wall in bending will not extend to inner cavity
Deformation, to keep the lumen size of bending place consistent, the stroke that cooling medium stream is crossed is consistent, and then ensures cooling effect, and
The safety of transformer station high-voltage side bus；Under the premise of identical tube chamber, whole ruler can be reduced compared with the structure of more square tubes splicing
It is very little, save space and material；It need not weld, workload is greatly reduced, improve process velocity.

Specific implementation mode
A kind of bend pipe accessory of square tube as shown in Figure 1 includes the pad 1 of cuboid made of cast iron or stainless steel, institute
State in pad 1, rear portion and square tube inner cavity coincide, front end face and square tube bending part inner cavity lateral wall cambered surface are coincide so that before it
Portion coincide with square tube bending part inner cavity；The rear end of the pad 1 screw thread be detachably connected with stainless steel made of connecting rod
2, on the connecting rod 2 threads turn be connected with stainless steel made of nozzle postive stop baffle 3；On the nozzle postive stop baffle 3
It is also equipped with tube chamber supporting mechanism, the tube chamber supporting mechanism includes the guide sleeve 4 for being connected to 3 back side of nozzle postive stop baffle, institute
It states guide sleeve 4 to be also made of stainless steel, be welded to connect with nozzle postive stop baffle 3,4 inner cavity of the guide sleeve is also by threads turn
In connecting rod 2, the thread turns needed for nozzle postive stop baffle 3 can be reduced, and then reduce thickness, the sliding of 4 outer wall of the guide sleeve
It is connected with the sliding block 5 of annular, detent mechanism, in the present embodiment, detent mechanism are provided between the guide sleeve 4 and sliding block 5
Using be arranged 4 outer wall of guide sleeve several annular, section be hemispheric convex stupefied 8, and be arranged in 5 inner wall of sliding block
Annular groove, the internal diameter of sliding block 5 is more than the outer diameter of guide sleeve 4, less than convex stupefied 8 outer diameter, and needs using slightly having elasticity
Material be made, such as plastics, when use, which needs to apply certain strength, makes the annular groove of 5 inner wall of sliding block be buckled on convex stupefied 8,
Or it is detached from from convex stupefied 8；The front end of the sliding block 5 is also rotatably connected to four supporting rods 6, is set on the nozzle postive stop baffle 3
It sets there are four pilot hole 7, four supporting rods, 6 front end passes through pilot hole 7 obliquely outward correspondingly, the support
6 preferred steel wire of bar has higher intensity and elasticity.
In use, the square tube lumenal cross-section of bending selects suitable pad 1 as needed, it is connected to connecting rod 2
Front end, further according to the position of square tube bending, then pad 1 is inserted into square tube inner cavity, directly by the position of adjustment nozzle postive stop baffle 3
It is close to nozzle to nozzle postive stop baffle 3, then pushes sliding block 5 that 6 front end of supporting rod is made to expand outwardly, until the annular of sliding block 5 is recessed
Slot is buckled in can make 6 front end of supporting rod be close to square tube inner wall and slightly deform on certain one convex stupefied 8, complete positioning, can be with other side
Pipe carries out Bending Processing；After process finishing, pushing back sliding block 5 makes supporting rod 6 collapse, and extracts pad 1 out.
