Description
Technical field
The utility model belongs to aviation shape extrusion field, particularly relates to a kind of stretch bending resistive block.
Background technology
Stretch bending technology is widely used in each manufacturing enterprise, and this kind of process not only may be used for extrudate, and also may be used for the curved material of plate, each Aviation Enterprise all has this technology, and for the processing and manufacturing of various airplane parts.Current Kazakhstan flies to have the part using this technology to produce and reaches hundreds of kind.But along with the globality of airplane component improves, the specification of airplane parts is also increasing, current capacity of equipment can not be applicable to the processing of the curved material part of plate, its immediate cause is the width (as shown in Figure 1) that the part width of the curved material part of plate has exceeded equipment jaw, causes this type of part processing difficulties.Turning round and look at a kind of method of urgent need makes current capacity of equipment can meet the processing needs of large gauge part.
Summary of the invention
Goal of the invention: a kind of a kind of stretch bending resistive block that can block stretch bending distortion is provided.
Technical scheme: a kind of stretch bending resistive block, for both sides arrange reeded aluminium block structure, be provided with the penetrating gap parallel with groove direction in the middle part of described aluminium block, described seam shape is consistent with section bar.
Beneficial effect: the utility model stretch bending resistive block can make the working ability of existing equipment be greatly improved, and the principle of stretch bending resistive block is simple, easy to use, low cost of manufacture, a set of stretch bending resistive block is applicable to various parts, the fund of large number quipments transformation can be saved, enhance productivity.
Accompanying drawing explanation
Fig. 1 is part, jaw schematic diagram;
Fig. 2 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, refers to Fig. 1 to Fig. 2.
The utility model makes full use of original stretch bending technique, and improves original technique, increases stretch bending resistive block, the range of application of original technique is expanded, meet the needs of part processing.
Along with the raising of current aircraft tonnage, the specification of part continues to increase, and some original process equipments can not meet the process requirements of existing part.Stretch bending process equipment limits due to jaw, can not meet part processing needs.
By the development test to original technique, discovery can to the curved material of plate carry out folding after put into jaw, the stretch wrap forming of part can be realized equally.But after associated jaw portion is folding, along with the increase of part (in Fig. 1, arc-shaped is part) stretch bending power, the folding fold of jaw (being jaw below circular arc in Fig. 1) folded part inwardly can conduct to inside parts, causes part forming failure (as Fig. 1).The folding fold conducting problem solving associated jaw portion is the key of head it off.
In order to solve the problem, devise stretch bending resistive block (as Fig. 2).A kind of stretch bending resistive block, for both sides arrange reeded aluminium block structure, be provided with the penetrating gap parallel with groove direction in the middle part of described aluminium block, described seam shape is consistent with section bar.
Before being shaped, section bar is inserted in resistive block gap, resistive block position between jaw and mould during shaping, when associated jaw portion fold inwardly conducts, encounters the obstruction of resistive block, cause fold inwardly to conduct, solve the folding fold conducting problem of associated jaw portion.
The utility model stretch bending resistive block can make the working ability of existing equipment be greatly improved, and the principle of stretch bending resistive block is simple, easy to use, low cost of manufacture, a set of stretch bending resistive block is applicable to various parts, can save the fund of large number quipments transformation, enhance productivity.
