Изобретение относитс к области обработки металлов давлением, в частности к обработке кромок отбортовкой , и может быть использовано при производстве деталей из листовых заготовок с отверстием и бортом вокруг него.The invention relates to the field of metal forming, in particular, to edge processing, and can be used in the manufacture of parts from sheet blanks with a hole and a flange around it.

Известен способ получени детали с отверстием и бортом вокруг него , при котором заготовку зажимают и воздействуют на нее деформирующим инструментом, сообщают относительное вращение заготовке и инструменту 1.A known method for producing a part with a hole and a flange around it, in which the workpiece is clamped and subjected to it by a deforming tool, reports the relative rotation of the workpiece and tool 1.

Известный способ позвол ет получать борт вокруг отверсти , направленный параллельно оси отверсти , что ограничивает номенклатуру производимых деталей.The known method allows to obtain a board around the hole, directed parallel to the axis of the hole, which limits the range of parts produced.

Целью изобретени вл етс расширение номенклатуры получаемы с деталей путем производства деталей с т орообразным бортом.The aim of the invention is to expand the nomenclature obtained from the parts by producing parts with a side board.

Цель достигаетс тем, что по способу получени детали с отверстием и бортом вокруг него, при котором заготовку зажимают, воздействуют на нее деформирующим инструментом и сообщают относительное вращение заготовке и инструменту, в заготовке предварительно получают отверстие, усили зажима в процессе образовани борта прикладывают к недеформиру10 емой части заготовки, усили деформировани прикладывают к поверхности, ограничивающей отверстие, последовательно по участкам в направлении от оси отверсти к периферии.The goal is achieved by the method of obtaining a part with a hole and a flange around it, in which the workpiece is clamped, a deforming tool is applied to it and the relative rotation of the workpiece and the tool is reported, a hole is preliminarily prepared in the workpiece, the clamping force is applied to the non-deformable portions of the workpiece, deformation forces are applied to the surface bounding the hole, successively in sections in the direction from the axis of the hole to the periphery.

На фиг. 1 показана заготовка с отверстием; на фиг. 2 - образование борта в начальной стадии; на фиг.З то же, в конечной стадии.FIG. 1 shows a blank with a hole; in fig. 2 - formation of the board in the initial stage; in FIG. 3 the same in the final stage.

Claims

In the sheet blank 1, in any known way, an opening is obtained (mainly through). Then the workpiece is clamped on the periphery so that. clamping forces are directed 395 from the hole axis to the periphery (not shown). The deforming tool 2 is inserted into the hole. Further, the relative rotation of the workpiece and the tool is combined, and it does not matter if the workpiece or the tool rotates. Provide contact of the workpiece with the tool. A tool interacting with the surface of the hole, or part of it, heats the metal in the contact zone as a result of friction between them. The metal is heated to a plastic state, and since the heated metal of the workpiece is subjected to a deforming tool in the direction perpendicular to the axis of the part, the metal also flows in the direction perpendicular to the axis of the part. The flanging is carried out sequentially in sections along the contour of the hole. When exposed to a tool, the working part of which has a length greater than the thickness of the sheet blank, the beads are obtained from both sides of the blank. The feeding of the deforming tool can be carried out in the radial direction or at an angle to the surface of the tool to be treated in a plane perpendicular to the axis. An example of implementation of the method. A 5 mm thick L-63-type brass sheet was clamped in the pattern of a lathe and a 15 mm diameter hole was drilled in it. Reporting the spindle of the machine to 2000 rpm, inserting a deforming tool into the hole, which is L-shaped and fixed in the tool holder of the machine support, and created a contact of its working part with the hole surface. The billet metal was heated by friction to plasticity. A deforming tool was filed in the radial direction (along arrow P) and the metal was formed a toroid-shaped bead. Between the board and the workpiece while forming a cavity. By deforming a hole with a diameter of up to 27 mm, the bead diameter was equal to 35 mm. The implementation of the proposed method is available to any enterprise that has metal-cutting equipment, and provides for obtaining parts of a wide range, in particular, parts with hubs and necks. The invention of the method for producing a part with a hole and a flange around it, in which the workpiece is clamped, is applied to it by a deforming tool and the relative rotation of the workpiece and the tool is reported, in order to expand the range of parts obtained by producing toroidal parts. , in the preform, a hole is formed; a force deformation is applied to the surface bounding the hole, successively in sections in the direction from the axis of the hole to the periphery.
