A kind of plate folding circular arc mold
Technical field
The utility model belongs to the metal sheet Bending Mould technical field in field of machining, particularly relates to a kind of plate folding circular arc mold.
Background technology
For the bending of metal sheet, the working condition of legacy equipment is processed on lathe, operating process more complicated, need the degree of depth and the panel thickness of given bed die total height and bed die flex area inside groove, drift falls to contacting with plate, then continues the angle of bend that decline one predetermined altitude reaches needs.In numerical control bender, mathematical computations is carried out to some parameters that the falling head of drift presets according to operator, then, machine is pre-set, to realize the angle of bend of sequencing.Visible operating process is very complicated, and accumulated error is large, and bending result is not best, because such technology, the angle of acquisition many times can be made with error, often need again to revise, add production technology, thus increases cost.For solving the problems of the technologies described above, patent ZL201220311573.2 discloses a kind plate bending Inner arc mould, comprise drift and bed die, this bed die is made up of mold block and base, two mold block are symmetrical fixing two D type structures, the cambered surface of two D mould blocks is inside, and form groove between two D mould blocks, described drift lower end is cone structure.Described groove width is 90 ~ 100mm, is preferably 96mm.Drift lower end is cone structure, drift and groove with the use of.Although technique scheme solves above-mentioned technical problem to a certain extent, but, it is urgently to be resolved hurrily still to there is many technical problems in this technical scheme itself, such as: in technique scheme, inventor adopts the groove formed between two D mould blocks that plate is bent into circular arc, but in the process of above-mentioned bending, the plate deflection being positioned at circular arc both sides on workpiece is comparatively large, and this just easily makes final finished product not meet concrete instructions for use.
Summary of the invention
The utility model provides one compared to existing technologies for solving in known technology the technical problem that exists, and structure is more simple, and it is more convenient operate, and circular arc mold rolled over by the plate of the defect and deficiency that effectively solve the existence of existing bending equipment.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of plate folding circular arc mold, comprise: upper module and lower module, described upper module comprises installing handle for connecting staking punch and punch integrated with installing handle, described punch cross section is rhombus and its underpart is provided with the circular arc head that radian is less than 90 degree, two seamed edges that described circular arc head two ends are adjacent respectively are tangent, described lower module is on the table affixed and which is provided with die, and described die is made up of the arc-shaped groove matched with punch and the guiding angle tangent with groove two ends.
The utility model can also adopt following technical measures: the upper edge of described guiding angle is provided with chamfering.
The utility model can also adopt following technical measures: the radian of described circular arc head is 60 degree of-90 degree.
The utility model can also adopt following technical measures: the height of described guiding angle is 1-3 times of described groove height.
The utility model can also adopt following technical measures: the angle of described guiding angle is 40-60 degree.
The advantage that the utility model has and good effect are:
For solving technical problem of the prior art, the utility model provides technique scheme.
Compared with prior art, improvements of the present utility model are as follows:
The first: the utility model improves the structure of upper module, namely for connecting the installing handle of staking punch and punch integrated with installing handle, especially, the utility model design punch cross section is rhombus and its underpart is provided with the circular arc head that radian is less than 90 degree, two seamed edges that described circular arc head two ends are adjacent respectively are tangent, in this design, circular arc head is mainly used in plate bent into shape with groove match, the seamed edge of described punch, for compressing circular arc both sides plate shaping on workpiece, carries out bending operation with limit circular arc head.
It two is: the utility model design lower module is on the table affixed and which is provided with die, and described die is made up of the arc-shaped groove matched with punch and the guiding angle tangent with groove two ends.Groove, as the major part accepted with punch, for for enough spaces are reserved in plate bending, guides the Main Function of angle to be reduce circular arc both sides plate deflection shaping on workpiece.
In sum, compared to existing technologies, the structure of upper module and lower module is more simple, and the operation of plate bending is more convenient for the utility model, has the defect and the deficiency that guide angle effectively can solve the existence of existing bending equipment above design groove.
