Abstract
The present invention is a kind of cold bend pipe with small radius of curvature shaped device and method thereof of being used for.It is to adopt the circulation of hinge plug to put in the former pipe, the pushing processing method of push rod portion and hinge plug joint butt splice; Its device is to adopt the top connection-core clavus by push rod to dock 2～4 joint hinge plug effects in the former pipe, make the hinge plug in fairlead by and bending is freely in bending channel.Compared with the prior art the present invention has the working (machining) efficiency height, the characteristics that hinge plug joint is not easy to wear, easy to maintenance, and change or make easily hinge plug joint, can process the elbow below 1.5 inches.
Description
The present invention relates to a kind of bending and molding device, particularly a kind of cold bend pipe with small radius of curvature shaped device and method thereof of being used for.
According to the described content of Chinese patent 87210664.0 utility models:, provide a kind of hinge plug and back-stop mechanism that push rod connects that have to the cold bend pipe with small radius of curvature shaped device.
Boeing Co.'s bend pipe handbook is also mentioned the cold type device that pushes into for little bilge radius of bending or little light-wall pipe in addition, is the multi-ball type mandrel that adopts a kind of hinge joint with ball-shaped to be connected, and is connected with push rod.
Above-mentioned two kinds have the hinge plug that push rod connects, and the subproblem of its existence is that working (machining) efficiency is low, can not add elbow below 1.5 inches, and the hinge plug is fragile, and especially at the position of cutting somebody's hair, maintenance is inconvenient again, has only and changes the hinge plug that push rod connected.In order to overcome the problems referred to above, the present invention has designed the processing mode of a kind of push rod portion and hinge plug butt splice, has solved the small-bore cold method that pushes into the type elbow, has promptly improved working (machining) efficiency, makes parts not easy to wear.Make easy to maintenancely again, make plug joint easily.
It is not easy to wear to the purpose of this invention is to provide a kind of plug parts that make, and has solved the small-bore cold type elbow that pushes into, and improves the cold bend pipe with small radius of curvature shaped device and the method thereof of working (machining) efficiency.
The present invention adopts such method to realize: cold bend pipe with small radius of curvature shaped device and method thereof are to adopt the circulation of hinge plug joint to be placed in the former pipe, the pushing processing method of push rod portion and hinge plug joint butt splice.Its device is the whole workpiece butt joint that employing has the inner tube of a tyre and each semicircle of cover tire outside the bend pipe of bend pipe inboard, constitute the bending channel of the required curvature of bend pipe, dock fairlead in outer rim with an end of cover tire simultaneously, connect aforesaid bending channel, constitute former pipe introduction channel near the inner tube of a tyre; On the axial line in bending channel, by concentric with bending channel and to the corresponding to hinge plug of former pipe internal diameter joint, top connection-core clavus by push rod docks 2～4 joint hinge plug effects in the former pipe, make the hinge plug in fairlead by and bending is freely in bending channel.
The inner tube of a tyre is a rotary state when promoting hinge plug and former pipe.
Compared with the prior art the present invention has the working (machining) efficiency height, and the hinge plug is not easy to wear, characteristics easy to maintenance, and change or make easily hinge plug joint, and can process elbow below 1.5 inches, guarantee the requirement of machining accuracy.
Concrete structure of the present invention and embodiment are provided by the following drawings.
Fig. 1 is the general structure sectional structure schematic diagram of cold bend pipe with small radius of curvature shaped device of the present invention and method thereof.
Fig. 2 is the enforcement state diagram of cold bend pipe with small radius of curvature shaped device of the present invention and method thereof.
Fig. 3 is cold bend pipe with small radius of curvature shaped device of the present invention and method push rod top structure sectional structure schematic diagram that part connects thereof.
Fig. 4 is the cross-sectional view of cold bend pipe with small radius of curvature shaped device of the present invention and the former pipe of method thereof.
Below in conjunction with accompanying drawing concrete structure of the present invention and embodiment are done with further instruction.
See shown in the figure (1): cold bend pipe with small radius of curvature shaped device and method thereof are to adopt hinge plug joint (1) circulation to be placed in the former pipe (14), and the top (6) on the push rod (12) is connected with plug joint (9) and saves the pushing processing method of (1) butt splice with the hinge plug.Its device be in adopting revolution tire axle (4) fixing in revolution tire (5) and constitute the bending channel of bend pipe with outer fixed mould tire (10); At one of an end of bending channel butt joint fairlead (11) with the bending channel concentric, in fairlead (11), has a push rod (12), fore-end at push rod (12) has the top (6) that is connected by top axle (7), on top (6), has the plug joint (9) that connects by carrier bar (3), carrier bar (3) is with on carrier bar axle (2) institute top that is fixed on (6) and the plug joint (9), relative 2～4 the hinge plug joints (1) that are connected to plug joint (9), hinge plug (1) also is to adopt carrier bar (3) and by carrier bar axle (2) fixed core clavus, can make former pipe (14) bend to the elbow (8) of required radius of curvature like this.
See shown in Figure 4: processing cold push away small curvature radius bend pipe before, at first former pipe material is processed into former pipe (14), does not wait at two base angles, front end α is 28 °, rear end α
1It is 41 °.
See shown in Figure 3: push rod (12) is gone up the top (6) and plug joint (9) top that connect and is overall structure (13), and it is shaped as the cross section is trapezoidal shape, and the leading section demifacet is a cylindrical structure.Column structure top (13) can replace plug joint (9), and the working (machining) efficiency when making push-making angle fitting improves.
See shown in Figure 2: the duty of cold bend pipe with small radius of curvature device.During pushing, one cover plug joint (1) is put into former pipe (14), put into the fairlead (11) of mould then together again, start hydraulic mandril (12), promote top (6) and plug joint (9), advance in the former pipe (14), and continuation promotes former pipe (14) and a cover hinge plug (1) together enters in the bending channel of mould, 90 ° of elbows of forced shaping (8), after this start hydraulic mandril (12), drive top (6) and plug joint (9) and get back to original position together, again a cover hinge plug joint (1) that is installed in another former pipe (14) is put into fairlead (11), start hydraulic mandril (12), promoting top (6) and plug joint (9) pushes in the former pipe (14) together, the front end of this former pipe (14) pushes up the rear end of molded elbow (8), push rod (12) continues ejection head (6) and plug joint (9) advances, when forcing pushing to be shaped to elbow (8) the 2nd former pipe (14), end, previous elbow (8) is pushed out the bending channel mould and sends in the reeling machine, again hinge plug joint (1) release is returned to push machine and put into former pipe (14), recycle, finished a working cycles, the rest may be inferred in later pushing processing.
