Abstract
The utility model discloses a metal bent head forming device in the technical field of a metal pipe fitting forming device and aims at solving the problems of low work efficiency, serious environment pollution and high cost of metal pipe element bending in the prior art. The metal bent head forming device comprises a core bar and is characterized in that the core bar consists of a cord bar rod in a linear shape and a core bar head in an arc shape, the core bar head is connected with the tail end of the core bar rod, the cross section diameter of the core bar head is in a gradually enlarged shape from the small size to the large size, the start end of a core mold rod is provided with a pushing plate connected with a hydraulic driving device, the pushing plate is in clearance fit with the core bar rod, and the outer periphery of the core bar is also sheathed with an induction coil. The metal bent head forming device is used in the metal pipe fitting bent head forming process, the structure is simple, the cost is low, the metal bent head forming device can be used for producing metal bent heads with different wall thicknesses, in addition, the work procedures are few, the production period is short, the work efficiency is high, no pollution exists, and the body health of operators is not injured.
Description
Technical field
The utility model relates to a kind of metal tube shaped device, particularly a kind of forming of metal elbow device.
Background technology
In the prior art, a kind of pipe fitting bending method is arranged, use a kind of technique of filling, fill in pipe fitting, such as filling with plumbous, filling with wax or steel ball etc., what filling lead adopted is to add the lead suitable with pipe fitting internal diameter volume at inside pipe fitting, need through blanking, molten lead, fill with lead, moulding, deleading, scarfing 6 procedures, the pipe fitting surface also needs to remove the residual lead of pipe fitting inner wall through the mode of overpickling, is engaged in for a long time plumbous work, all can cause larger harm to the environment of plant and workman; Filling wax is the same with filling lead also will be through 6 procedures, and its manufacturing procedure is comparatively loaded down with trivial details, cause the production cycle of pipe fitting bending to prolong; 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.
For overcoming the deficiency in the above-mentioned technology, also has a kind of metal bends extrusion forming device in the prior art, comprise mould, 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, die cavity run through mould and with the mould exterior, die cavity is comprised of straight length and bend loss, be provided with in the straight length be used to the pressure-ram that promotes pipe fitting to be processed, external diameter and the inside diameter of straight pipe section of pressure-ram are suitable; Be provided with in the 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.Though this device has been simplified the bend pipe operation, and pollution-free in the forming process, not encroach on operating personnel healthy, but because the gap of leaving between the inwall of elbow extruding core and die cavity is certain, so this device can not be used for the bend pipe production of different wall flexibly, has greatly limited its scope of application.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple in structure, easy to operate, operation is few, pollution-free and can be used in the forming of metal elbow device that bends the different wall pipe fitting.
The purpose of this utility model is achieved in that a kind of forming of metal elbow device, comprise plug, described plug is comprised of the linearly mandrel stem of type and curved core head, and described core head is connected in the mandrel stem end, the ascending flaring shape that is of core head diameter of section; The top of described core bar is provided with the slurcam that links to each other with fluid pressure drive device, described slurcam and mandrel stem matched in clearance; The periphery of described plug also is set with induction coil.
During the utility model work, first several pipe fitting blanks are set on the mandrel stem, fluid pressure drive device drives slurcam promotion pipe fitting blank and moves to core head, the pipe fitting blank is after the induction coil heating, continuation advances along core head, the ascending reducing flaring of pipe fitting, until come off from core head, the forming of metal elbow operation is finished.Compared with prior art, the beneficial effects of the utility model are: metal bends simple in structure, with low cost, as to can be used for the production different wall; Operation is few, with short production cycle, high efficiency, and pollution-free, not encroach on operating personnel healthy.
As further improvement of the utility model, described induction coil is arranged at the joint location place of mandrel stem and core head, carries out preheating before metal tube bends, and can make bending radius more even, and internal diameter is more smooth.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 mandrel stem; 2 core heads; 3 slurcams; 4 induction coils; 5 pipe fitting blanks.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, comprise plug, plug is comprised of the linearly mandrel stem 1 of type and curved core head 2, and core head 2 is connected in mandrel stem 1 end, the ascending flaring shape that is of core head 2 diameter of sections; The top of core bar 1 is provided with the slurcam 3 that links to each other with fluid pressure drive device, slurcam 3 and mandrel stem 1 matched in clearance; The periphery of plug also is set with induction coil 4, and induction coil 4 is arranged at plug, and 1 and the joint location place of core head 2.
During the utility model work, first several pipe fitting blanks 5 are set on the mandrel stem 1, fluid pressure drive device drives slurcam 3 and promotes pipe fitting blank 5 to core head 2 motions, pipe fitting blank 5 is after induction coil 4 heating, continuation advances along core head 2, the ascending reducing flaring of pipe fitting, until come off from core head 2, the forming of metal elbow operation is finished.
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.
