Abstract
The utility model discloses a metal bend extrusion forming device, belongs to the technical field of metal tube extrusion devices, and aims at solving the problems of high bending cost, high environmental pollution and low work efficiency of a metal tube in the prior art. The metal bend extrusion forming device comprises a molding mould which is formed by two mould boards through mutual splicing. A mould cavity matched with the shape of a finished product is arranged inside the molding mould. The mould cavity penetrates through the molding mould and is communicated with the outside of the molding mould. The mould cavity is composed of a straight tube segment and a bend tube segment. An extrusion pushing rod for pushing a tube billet is arranged in the straight tube segment. The external diameter of the extrusion pushing rod is matched with the internal diameter of the straight tube segment. A bend extrusion core model which has the same camber with a finished bend is arranged in the straight tube segment. A gap is maintained between the bend extrusion core model and the mould cavity, and the thickness of the gap is at least the same as the wall thickness of the tube billet. The metal bend extrusion forming device is used for extrusion of the bend of the metal tube, can complete extrusion and bending of the metal tube through one-time molding, has no need for cooling, is short in production cycle, high in work efficiency, and simple in working procedures, has no pollution and does no harm to health of workers.
Description
Technical field
The utility model relates to a kind of metal tube pressurizing unit, particularly a kind of metal bends extrusion forming device.
Background technology
Traditional bent tube technique uses bending machine, guiding by bending machine, pipe is bent, but this technique is in tube bending, the position of tube bending is out of shape easily, may become flat, be ellipticity, cumbersome in the pipe fitting docking like this, and also the docking site is also than being easier to cause leakage.Therefore in the existing tube bending method, use a kind of technique of filling, in pipe, fill, such as filling with plumbous, filling with wax or steel ball etc., what fill with plumbous employing is to add the lead suitable with pipe fitting internal diameter volume at inside pipe fitting, needs through blanking, molten lead, fills with lead, moulding, deleading, scarfing 6 procedures, and the pipe fitting surface also needs to remove the residual lead of pipe fitting inner wall through the mode of overpickling, be engaged in for a long time plumbous work, all can cause larger harm to the environment of plant and workman; Fill with wax with fill with plumbous the same also will be through 6 procedures, the forming method of filling with plumbous and filling with wax needs that the chien shih pipe fitting cools off when a large amount of, will cause like this production cycle prolongation of pipe fitting bending; The method of steel ball need to be added steel ball repeatedly in forming process, needing more after moulding, exchange device carries out the steel ball shaping again, cause whole activity time long, the equipment that needs is also more, and also larger to the wearing and tearing of core rod, pipe fitting is also wrinkling easily, and these fillers in use can reduce or loss, and the cost of pipe fitting bending is higher.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides that the crooked cost of a kind of metal tube is low, low in the pollution of the environment, the metal bends extrusion forming device of high efficiency.
The purpose of this utility model is achieved in that a kind of metal bends extrusion forming device, comprise mould, described mould is made of two mutual amalgamations of template, the inside of mould is provided with the die cavity that is complementary with finished form, described die cavity run through mould and with the mould exterior, described die cavity is comprised of straight length and bend loss, is provided with in the described straight length be used to the pressure-ram that promotes pipe fitting to be processed, and external diameter and the inside diameter of straight pipe section of pressure-ram are suitable; Be provided with in the described bend loss and the crooked consistent elbow extruding of finished product elbow core, leave identical with tube wall thickness to be processed at least gap between the inwall of elbow extruding core and die cavity.
During the utility model work, at first the metal pipe blank is cleaned, and at metal pipe blank surface parcel one deck plastic foil; Then, the pipe blank is pushed die cavity from straight length by pressure-ram, the end of pipe is socketed on the elbow extruding core gradually, and pressure-ram continues the extruding pipe fitting, and pipe moves towards crooked along the gap between elbow extruding core and the mould intracavity wall; When the working end of the working end of pressure-ram and elbow extruding core leant, the elbow extruding was finished at last, withdrawed from successively pressure-ram and elbow extruding core, and die sinking can be taken out the elbow of extrusion modling.Compared with prior art, the beneficial effects of the utility model are: pipe need not cooling through pushing crooked one-shot forming, and is with short production cycle, high efficiency; Operation is simple, and is pollution-free, not encroach on operating personnel healthy.
As further improvement of the utility model, the cross section of described pressure-ram is rounded, and the working end end face of pressure-ram is provided with step surface, and described step surface is located at the pressure-ram axis with upper/lower positions; Described elbow extruding core is rounded along the projection of axis direction, and the working end end face of elbow extruding core is provided with the boss that is complementary with step surface.The axis projection of elbow extruding core is rounded, after withdrawing from, the working end can repair elbow, so that the end of elbow is rounded, the sub-blank of elbow extruding core Inserting Tube is convenient in the setting of elbow extruding core boss, makes pipe move towards crooked along elbow extruding core; Step surface on the end face of pressure-ram working end plays position-limiting action, when boss is resisted against on the step surface, and then elbow extrusion modling.
Description of drawings
Fig. 1 is that the utility model uses the status architecture schematic diagram.
Wherein, 1 template; 2 die cavitys; 3 pressure-rams; 301 step surfaces; 4 elbows extruding core; 401 boss; 5 pipe fittings to be processed.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, comprise mould, mould is made of the 1 mutual amalgamation of two templates, the inside of mould is provided with the die cavity 2 that is complementary with finished form, die cavity 2 run through mould and with the mould exterior, die cavity 2 is comprised of straight length and bend loss, is provided with in the straight length be used to the pressure-ram 3 that promotes pipe to be processed, and external diameter and the inside diameter of straight pipe section of pressure-ram 3 are suitable; Be provided with in the bend loss and the crooked consistent elbow extruding of finished product elbow core 4, leave identical with pipe 5 wall thickness to be processed at least gap between the inwall of elbow extruding core 4 and die cavity 2.The cross section of pressure-ram 3 is rounded, and the working end end face of pressure-ram 3 is provided with step surface 301, and step surface 301 is located at pressure-ram 3 axis with upper/lower positions; Elbow extruding core 4 is rounded along the projection of axis direction, and the working end end face of elbow extruding core 4 is provided with the boss 401 that is complementary with step surface 301.
If the end of pipe fitting need to be squeezed into specific shape, by the just in the end step enforcement finishing of axis projection shape that changes elbow extruding core 4, guarantee that the end of pipe fitting finally meets the requirements.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
