Abstract
The utility model provides a kind of inner liner stainless steel elbow bending mould, including bending die, bending die bottom and is respectively arranged with high-pressure water nozzle along tubing axial direction to be processed；The bending die is respectively equipped with tubing clamping plate along tubing radially opposite sides to be processed, and every piece of tubing clamping plate is connect by telescopic rod with independent control motor.The utility model is gradually curved tubing along bending die using current scour, uniform stressed, and preventing from bending suddenly causes liner layer damaged, greatly increases the service life of inner liner stainless steel pipe.
Description
Technical field
The utility model relates to tubular object extruding field, specifically a kind of inner liner stainless steel elbow bending mould.
Background technique
Liner two-phase stainless steel composite steel pipe is in steel pipe inner wall thickness 0.35mm-0.5mm stainless steel tube, and this bimetallic is compound
Steel pipe greatly improves corrosion resistance of steel pipe during water delivery, defeated hot water, defeated coal gas, defeated natural gas, oil transportation, surface light
The advantages of sliding, fluid resistance is small, and remains steel pipe mechanical intensity height, and welding can be used, ditch mortise, be threadedly coupled, good airproof performance,
It overcomes that coating steel pipe is perishable, is gas transmission, water delivery, oil transportation using the defect of the plastic tube of hot-melt adhesive paste easy leak and aging
The ideal product of the upgrading of steel pipe.
Inner wall of the pipe forms one layer of very thin chromium oxide film internal lining pipe to liner two-phase stainless steel composite steel pipe in use,
The film prevents metal from continuing to aoxidize, therefore stainless steel has strong corrosion resistance, can not only bear the corrosion of water and air, and
And the corrosion of weak acid and weak base can be born.
Current stainless steel bend usually carries out heating bending and 2 butt welding to straight tube between 1mm-3mm due to thickness
Molding, for liner two-phase stainless steel composite steel pipe, since the stainless steel of liner is usually than relatively thin 0.3-0.5mm, direct bending or
Heating, welding are easy to cause the breakage of inner liner stainless steel pipe to cause product development to fail.
Utility model content
The utility model in order to solve problems in the prior art, provides a kind of inner liner stainless steel elbow bending mould, benefit
It is gradually curved tubing along bending die with current scour, uniform stressed, preventing from bending suddenly causes liner layer damaged, greatly increases
The service life of inner liner stainless steel pipe.
The utility model includes bending die, bending die bottom and is respectively arranged with high pressure along tubing axial direction to be processed
Sprinkler head；The bending die is respectively equipped with tubing clamping plate along tubing radially opposite sides to be processed, and every piece of tubing clamping plate passes through flexible
Bar is connect with independent control motor.
It is further improved, the high-pressure water nozzle of bending mould bottom has the independent spout of several hydraulic pressure.It is adjusted when processing every
The hydraulic pressure of a spray head gradually decreases centre to the hydraulic pressure on both sides, the stress that tube wall generates when can effectively reduce bending.
Utility model works method are as follows: tubing to be processed is put into below bending die, utilizes control motor control two sides
Tubing clamping plate clamps tubing, and the high-pressure water nozzle of bottom sprays high pressure water flow against tubing, and intermediate hydraulic pressure is high, and two side hydraulic pressures are low,
Tubing can be made to be folded over to high pressure water flow is sprayed into inside tubing along the high-pressure water nozzle of tubing axial direction to be processed simultaneously
The breakage of liner layer is reduced in journey.
The utility model beneficial effect is: being gradually curved tubing along bending die using current scour, uniform stressed is prevented
Only bending suddenly causes liner layer damaged, greatly increases the service life of inner liner stainless steel pipe.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model process principle figure.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
The utility model structure is as shown in Figure 1, include bending die 1,1 bottom of bending die and axial along tubing to be processed 2
Direction is respectively arranged with high-pressure water nozzle 5；The bending die 1 is respectively equipped with tubing clamping plate 3 along tubing radially opposite sides to be processed,
Every piece of tubing clamping plate 3 is connect by telescopic rod 4 with independent control motor.
It is further improved, the high-pressure water nozzle 5 of bending mould bottom has the independent spout of several hydraulic pressure.It is adjusted when processing every
The hydraulic pressure of a spray head gradually decreases centre to the hydraulic pressure on both sides, the stress that tube wall generates when can effectively reduce bending.
As shown in Fig. 2, tubing to be processed is put into below bending die when utility model works, control motor control is utilized
Two sides tubing clamping plate clamps tubing, and the high-pressure water nozzle of bottom sprays high pressure water flow against tubing, and intermediate hydraulic pressure is high, two side hydraulic pressures
It is low, while tubing can be made curved to high pressure water flow is sprayed into inside tubing along the high-pressure water nozzle of tubing axial direction to be processed
The breakage of liner layer is reduced during folding.
There are many utility model concrete application approach, and the above is only the preferred embodiment of the utility model, should
It points out, for those skilled in the art, without departing from the principle of this utility model, can also make
Several improvement out, these improvement also should be regarded as the protection scope of the utility model.
