Abstract
A metal tube reducing appliance relates to a mechanical apparatus which is used for the reducing of the end portions of metal tubes, and the metal tube reducing appliance comprises a body, rollers and an end cap. The body is provided with a bore at the axial center, and 3 to 9 rollers are positioned in the bore, male thread is manufactured on an excircle, female thread and a through-hole are manufactured on the end cap, and the rollers are limited in the bore through the connection of the female thread of the end cap and the male thread of the body, the form of the bore which id positioned near one end of the body axial center can be conical, drum-type or concave, but the external contour of the roller can be cylindrical, conical, drum-type or concave. With the utility mode, the reducing of various metal tubes according to arbitrary reducing coefficient can be carried through, and the utility model has the advantages of simple structure, low cost of utility apparatus, high processing efficiency, low defective index and excellent quality of workpieces.
Description
Affiliated technical field
The utility model relates to a kind of mechanical device that is used for metal pipe material is carried out end diameter reducing.
Background technology
At present, general metal tube undergauge method mostly is to adopt the undergauge mould to carry out on press, and also having a kind of method is to adopt special-purpose spinning machine to carry out spinning method undergauge by spinning roller or friction pulley (comprising brake pad).More than these undergauge methods mostly exist frock complexity, equipment cost height, working (machining) efficiency is low and percent defective is higher, the frictional heating important disadvantages.The pressing undergauge also is subjected to the restriction of undergauge coefficient in addition.
Summary of the invention
The utility model provides a kind of metal tube Reducer, can the high-quality end diameter reducing of finishing metal tube.
The technical scheme that its technical problem that solves the utility model adopts is: the device of metal tube Reducer is provided with endoporus in the axle center, and is placed with 3 to 9 rollers in the hole, is processed with external screw thread on the cylindrical; Be processed with internal thread on the end cap and be connected with device external screw thread on one's body with through hole and by the internal thread on the end cap roller is limited in the endoporus, the endoporus pass that is provided with by an end in device body axle center can be taper, cydariform or spill; And the roller outline can be cylindrical, conical, cydariform or spill.This utility model can be carried out undergauge by any undergauge coefficient with various metal tubes, and it is simple in structure, use that equipment cost is low, working (machining) efficiency is high, percent defective is lower, workpiece quality is good, the deficiency that has existed when having overcome present general metal pipe material undergauge preferably.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. device bodies among the figure, 2. roller, 3. end cap, 4. workpiece.
Specific implementation method
In Fig. 1, on the axis of device body (1), be provided with endoporus, be placed with (2) 3 to 9 of rollers in the endoporus, internal thread by end cap (3) is connected with the external screw thread of device body roller (2) is limited in and forms a cover metal tube Reducer in the device body endoporus, this Reducer can be installed in the taper hole on the tail stock, metal tube is installed on the scroll chuck of lathe, start lathe during work, at this moment the endoporus of roller (2) and device body (1), the metal tube cylindrical is done rolling movement respectively, simultaneously by the wheel feed on the tail stock, force the metal tube distortion in rolling, finally form needed undergauge metal tube, be i.e. workpiece (4).The utility model also can service efficiency can be higher on special equipment.
Claims (3)
1. a metal tube Reducer is made up of device body, roller, end cap, it is characterized in that: the device of metal Reducer is provided with endoporus in the axle center, and on device body cylindrical, be processed with external screw thread, in device body endoporus, be placed with 3 to 9 rollers, be processed with through hole and internal thread on the end cap, and be connected by the external screw thread of internal thread with the device body, roller is limited in the device body endoporus.
2. the device body of metal tube Reducer according to claim 1 is characterized in that: the endoporus pass that is provided with by an end in the axle center can be taper, cydariform or spill.
