The utility model reduces the resistance generated during axial propelling diameter shrinkage, and can be used for shaping the heads of steel pipes with hard materials and copper and aluminium pipes with soft materials with diameter shrinking.

Description

A metal-pipe spinning system machine

The utility model relates to the secondary process equipment of metallurgical tubing, relates to a kind of metal-pipe spinning system machine particularly, the system operation during it is applicable to before the crude metal tube-drawing.

The drawing processing of the middle thick steel pipe of domestic current, copper pipe, stainless steel tube etc. all is to reach required all size size by the extra heavy pipe base through drawing several times.And tube head must be burnt in stove before the drawing red again on pneumatic hammer, the forcing press forging attenuate, purpose is can be by the mould of drawing, making the clamp of drawbench block tube head can drawing.The major defect of this technical matters: the one, consumes energy causes environmental pollution; The 2nd, waste very much tubing because of the forging tube head is lack of standardization; The 3rd, personnel selection is many and efficient is low; The 4th, must cause production cost height, profit low for above-mentioned reasons.

The applicant's of the utility model application utility application: " metal pipe material dynamic model drop-head the machine " (applying date: 1994.9.15; Application number is 94241424.1) can solve the major defect of above-mentioned existing technology substantially.This system machine comprises a main frame, one Hydraulic Station and a voltage case, described main frame comprises a lathe bed, on lathe bed, fixing at least one pipe fluid power chuck, be located at slidably on the track-type facilities on the described lathe bed but also have straight line to move the support that pressure head (mould) is housed, and the center of described pressure head and described fluid power chuck are on same the center line.The undergauge of the tubing of the steel that the suitable material of a this system machine is hard, but its shortcoming is to contraction copper pipe and aluminium-alloy pipe, because material is soft, when the mould that contracts advances system, causes the short neck chap of the caliber that is contracted and the incompatibility drawing.

The purpose of this utility model is the shortcoming that solves a prior art system machine, and an a kind of system machine of the resistance can reduce the axial advance undergauge time is provided.

For realizing above-mentioned purpose of the present utility model, the utility model provides a kind of metal-pipe spinning system machine, comprise a main frame, one Hydraulic Station and an electric cabinet, described main frame comprises a lathe bed, on described lathe bed, fixing at least one pipe fluid power chuck, but the support that pressure head is housed that also has straight line to move is contained on the track-type facilities that is located on the described lathe bed slidably, and the center of described pressure head and described fluid power chuck are on same the center line, it is characterized in that described pressure head is a spinning head, advance at described support and carry out undergauge described spinning head of when operation and drive by transmission device and rotate.

Best, described spinning head has 180 ° three the fixing rolling wheel supports of being separated by mutually, each described rolling wheel support is provided with the roller of a band tapering, be fixed on the pivot pin of establishing on the described rolling wheel support with bearing arrangement, contract through the tubing head be inserted in the space that three set rollers surround, when described spinning head rotates, head and roller itself that described roller is clamped tubing rotate around described pivot pin, and the resistance when making described pressure head axial advance undergauge reduces greatly.

Best, the rotating speed of described spinning head is 200-1200 rev/min.The rotating speed of described spinning head is 300-600 rev/min of the best.

Owing on the basis that this practical practical characteristics is " at metal pipe material dynamic model drop-head machine " slide plate dynamic model axially advances and retreat, add a spinning head and drive three special rollers rotations, the resistance that produces in the time of can reducing the axial advance undergauge widely like this.Thereby can adapt to the hard thin-wall stainless steel of material, charcoal steel pipe undergauge system head, also applicable to the soft copper of material, aluminum pipe undergauge system head.

Below by drawings and Examples a system of the present utility model machine is described, in the accompanying drawing:

Fig. 1 is the structural representation of the utility model metal-pipe spinning system machine;

Fig. 2 is the front view of the spinning head of the utility model metal-pipe spinning system machine;

Fig. 3 is the side view of the spinning head of the utility model metal-pipe spinning system machine.

As shown in Figure 1, a metal-pipe spinning system of the present utility model machine, the same with existing a kind of metal pipe material system machine, comprise a main frame 10, one Hydraulic Stations 7 and electric cabinet 5.Main frame comprises a lathe bed 9, at least one pipe fluid power chuck 2 (being two in the present embodiment) is fixed on the lathe bed 9, also have the support 30 that 8, one of track-type facilities are equipped with pressure head 3 to be contained in slidably on the track-type facilities 8, the advance and retreat of this support 30 are activated by hydraulic jack 4.

The improvement of a metal-pipe spinning system of the present utility model machine is that above-mentioned pressure head 3 makes a spinning head 3, advances when carrying out the undergauge operation at support 30, and this spinning head 3 rotates.In one embodiment, spinning head 3 has 180 ° three the fixing rolling wheel supports 31 of being separated by mutually, each support is provided with the roller 32 of a band tapering, be fixed on the pivot pin of establishing on the rolling wheel support 30 33 with bearing arrangement, want the head of undergauge to be inserted in the space that these three rollers surround, when spinning head 3 rotations, roller is clamped head and the roller 32 of wanting undergauge tubing and itself is rotated around pivot pin 33, and the resistance when making pressure head 3 axial advance undergauges reduces greatly.In one embodiment, the rotating speed of spinning head 3 is 200/1200 rev/min, and is best, and the rotating speed of spinning head 3 is 300-600 rev/min.

A metal pipe material system of the present utility model machine is operated as follows: at first inserting in the chuck 2 tubing of head undergauge, clamp securely, and stretch out in the space that three rollers that head stretches into spinning head form.Energising then, Hydraulic Station 7 is started working, and under the control of control device 6, automatically the tubing with required drop-head clamps, and along with pressure in the hydraulic jack 4 increases, support 30 moves forward, spinning head 3 rotates, because roller 32 has suitable tapering to be convenient to want the tubing head of undergauge to import, when spinning head 3 rotated, roller 32 rolled on the tubing head of undergauge.After finishing undergauge, return spinning head support 30, unclamp anchor clamps 2, take off workpiece.Because the resistance of a system of the present utility model machine when the propelling undergauge of ram shaft reduces, thereby both can be suitable for the needs of the hard stainless pipe of material, charcoal steel pipe undergauge system head, also applicable to the soft copper of material, aluminum pipe undergauge system head.
