Abstract

The utility model discloses a cold-bending shaping machine for a spiral pipe, through which various spiral of metal pipes can be made, belonging to the metal cold-working machinery. The cold-bending shaping machine for a spiral pipe comprises a shaping clamping device which considers a central shaft as a rotary shaft and comprises a guide sleeve, a central sleeve, a radius supporting rod, a supporting plate, a clamping device frame, a force application disc, a shaping wheel, etc. and a circular or semi-circular clamping fixture which is fixed on a base and considers the central shaft as a circle center and has certain screw pitch. The difficult that a common chemical enterprise has no special device to produce the spiral pipes for maintaining devices is solved. The utility model has the advantages of simple structure, low cost, good shaping quality, high efficiency, etc., and is suitable for a middle-sized and a small-sized enterprises to use.

Description

Cold-bending shaper for helix tube

The utility model discloses a kind of helix tube cold-bending forming machine that can make various spiral metal tubes, belong to the Machining Technology field.

At present, in the cooling device or heat exchanger apparatus that uses during chemical industry is produced, extensively adopted the helical pipe of all size to constitute.Because oxidation and corrosiveness are often damaged these pipelines, pose a big pressure to maintenance work, especially the processing and forming of helix tube is the complex work that general amateur factory is difficult to finish.Therefore, make production efficiency and the quality that a kind of simply constructed helix tube cold roll forming machinery can improve general chemical industry business equipment maintenance greatly.

Goal of the invention of the present utility model provides a kind of manual helix tube cold-bending forming machine.

Figure of description 1 is a structure front view of the present utility model.

Figure of description 2 is structure vertical views of the present utility model.In above-mentioned two accompanying drawings: 1 central shaft, 2 fairleads, 3 center, 4 radius poles, 5 support plates, 6 molds, 7 jig framves, 8 afterburning dishes, 9 briquetting rollers, 10 jig push rods, 11 directive wheel push rods, 12 directive wheels, 13 guiding push rod pins, 14 mold swing links, 15 mold disc, 16 add solenoid, 17 wedge locating blocks, fixing hole 18, groove 19, dovetail groove 20.

Constructing technology main points of the present utility model with one take central shaft as rotating shaft, the moulding jig that is made of fairlead, center, radius pole, support plate, jig frame, afterburning dish, briquetting roller etc. and one are fixed on that circle or the semicircle mold by a constant pitch take central shaft as the center of circle forms cold-bending shaper for helix tube on the base. Utilize the moulding jig that tubing radial effect power is bent into the helix tube shape with straight tube along the circular curve of mold.

Now, introduce structure situation of the present utility model according to Figure of description.A kind of helix tube cold-bending forming machine comprises one, and to be fixed on the base with central shaft 1 be that the circular or semicircle mold that a constant pitch is arranged in the center of circle and one are constituted with the moulding jig of central shaft 1 by rotating shaft, it is characterized in that:

1, circular or semicircle mold is by being fixed on some mold disc 15 on the central shaft with the circular or semi-circular shape of mold 6 support fixation, at the outer surface of mold 6 groove 19 that one cross section arranged is semicircular arc, one side of mold one ring-type has been installed with the fixing all-in-one-piece mold swing link 14 of mold 6, the outer of swing link 14 has dovetail groove 20 one;

2, the moulding jig is rigidly connected fixing by a center 3 that is enclosed within on the central shaft 1 with radius pole 4, a support plate 5 is housed in the end of radius pole 4, the jig frame 7 of a support plate 5 and a flute profile is spirally connected and is fixed together, installed one in jig frame 7 middle parts and the briquetting roller 9 of semicircular arc groove has been arranged with its rotating shaft all-in-one-piece outer surface, on the axle of briquetting roller 9 a foursquare prolongation is arranged, be connected with the reinforcing dish 8 of band square hole on the axle, a guiding push rod pin 13 also has been installed in jig frame 7 middle parts, fix a L type directive wheel push rod 11 above, in the short end of directive wheel push rod a directive wheel 12 has been installed, a jig push rod 10 is installed in the outside at jig frame 7, cover one adds solenoid 16 above, fixed a wedge locating block 17 in the bottom of jig frame, in addition, a fairlead 2 also has been installed on central shaft, and the interior overcoat of fairlead 2 is connected with center with central shaft respectively.

Assembling of the present utility model is performed such: central shaft is fixed on the base, on the swing link on the circular or semicircle mold fixing hole is arranged, with pre-buried bolt itself and base are fixed together, the center of moulding jig is enclosed within on the central shaft, support plate 5 matches to overlap with mold 6 the moulding jig is placed on circle or the semicircle mold, groove on the briquetting roller 9 on the moulding jig is corresponding with the groove 19 on the mold 6, the space of forming a circle, the wedge locating block 17 on the moulding jig fall into the location of matching in the dovetail groove 20 of mold swing link 14 outers.The interior cover of fairlead 2 is fixed on the central shaft 1, and overcoat is connected with center, has a pitch screw thread identical with mold pitch that interior overcoat bolt is fixed between the interior overcoat.

Working condition of the present utility model is straight metal tube to be put into the groove of mold, one end is fixed, the other end is placed along the mold tangential direction, give jig push rod and the reinforcing of directive wheel push rod simultaneously along tangential direction, can make straight tube constantly be processed to helical form along groove on the jig and briquetting roller travel direction.Because mold has a constant pitch in this process, and the moulding jig is moved axially along the center.Simultaneously, under the threaded function of fairlead, center also moves axially simultaneously, thereby the moulding jig is in all the time cooperate sliding mode stably, obtain good molding effect on mold, and more laborsaving.In addition, when moulding jig arrival metal tube end directive wheel can't be exerted pressure to it, rotatable afterburning dish was convenient to moulding to increase briquetting roller to the turning effort power of tubing.

Principal advantages of the present utility model is that simple structure, cost are low, the helix tube Forming Quality is good, working (machining) efficiency is high.

In the implementation process of the present utility model, is that the engineers and technicians in common mechanical field are known to each parts with material and processing, except that briquetting roller, directive wheel, jig frame used mechanical strength high high-quality steel or mould steel, miscellaneous part can adopt general carbon steel manufacturing.
