Description
Technical field
The present invention relates to shape extrusion technical field, in particular to shape extrusion fixture.
Background technology
Section bar is iron or steel and the material with some strength and toughness（Such as plastics, aluminium, glass fibre）By logical
Rolling is crossed, is extruded, the object with certain geometrical shape of the manufacturing process such as casting.Section bar can be divided into I-steel, channel-section steel, angle
Steel, round steel etc., present profile applications it is unusual extensively, the large number of rows such as train, subway, track traffic, curtain wall already pass through from
The not use of open form material, and the processing of section bar be unable to do without most of process equipment, existing shape extrusion by digital control processing
The heart is completed.
Section bar outer shape is different, and the flat vice in numerical control machining center can not clamp to be aided in, it is necessary to make fixture
Processing.The clamp structure of traditional numerical control machining center is complex substantially using profiling positioning method, and profiling is determined
There is gap in position, machining accuracy is not high, is not suitable for Precision Machining.
