Technical field
The utility model relates to automobile production field, particularly a kind of automobile backward flanging mould.
Background technology
Along with the development of society, market competition is more and more fierce, under competitive environment, cost will be direct one of important indicator affecting Business survival, the quality of product is not affected reducing entreprise cost while, most important to enterprise, for existing Die & Mould Market, when multiple operation structure, market great majority adopt the punching structure principle of single square impact flange, in multi-mould stamping procedure, plate profile needs accurately location, the each operation of patrix holding pad pressure is all different, profile integrality needs to limit for different structure, corresponding adjustment is all wanted to process to plate impression, not only strengthen die cost, and feeding brings difficulty after giving punching press, mould production efficiency is caused to reduce.In the production process of the numerous punching parts of body of a motor car, due to the structural design of punching parts, cause Sheet Metal Forming Technology need to arrange flanging process, but the impact of some factor such as flange angle and pressing direction, in punching production process because of die size exceed platen face or each process mould pressing direction inconsistence problems bring up technique can not layout, if after Mold Making is shaping, rethinking solution problems can be more difficult.
Utility model content
The utility model is for solving the problems of the technologies described above as providing a kind of effective solution stamping parts flange shaping, and structure is simple, avoids pressing direction skimble-scamble automobile backward flanging mould.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of automobile backward flanging mould, comprise upper die base and lower die base, also comprise flange cutter block, flange cutter block mount pad, drive guider, taper wedge and backhaul air spring, described flange cutter block is arranged on flange cutter block mount pad, described flange cutter block mount pad is arranged in lower die base, the bottom of flange cutter block mount pad is ramp structure, and matches with the side ramp structure of taper wedge; Described driving guider is arranged in upper die base, and the bottom driving guider is ramp structure, for matching with the opposite side ramp structure of taper wedge; Described taper wedge moves and is arranged in lower die base, and described backhaul air spring is arranged in lower die base, and is connected with taper wedge; Also include displacement transducer, institute's displacement sensors is arranged on flange cutter block mount pad.
The utility model beneficial effect is: promote taper wedge by driving guider and drive flange cutter block to carry out work, reach stamping parts flange shaping, can also ensure whether flange puts in place completely, and structure is simple by displacement transducer, pressing direction is unified, and cost of manufacture is cheap.
As a kind of preferred structure of the present utility model, in order to improve the problem that the pressure that flange cutter block is subject to cannot be detected, also include pressure sensor, described pressure sensor is arranged on flange cutter block.So can be real-time the pressure data that flange cutter block is subject to detected, have very large assistance dissection to the displacement of flange cutter block, durability degree.
As a kind of preferred structure of the present utility model, move to improve taper wedge, the problem of easily wearing and tearing, described taper wedge is moved by wearing plate and is arranged in lower die base always.So will move around by wearing plate, will become wear-resistant, long service life.
As a kind of preferred structure of the present utility model, drive guider to carry out repercussion to improve, the problem of easily fracture, described driving guider is arranged in upper die base by nitrogen spring.Like this will have a buffer stage, improve the compression strength driving guider, improve service life.

Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Please with reference to Fig. 1 and Fig. 2, known as shown in the figure, the utility model automobile backward flanging mould comprises upper die base 1, lower die base 2, flange cutter block 3, flange cutter block mount pad 4, drive guider 5, taper wedge 6 and backhaul air spring 7, guider 5 is driven to be arranged in upper die base 1 by pin and bolt, the bottom driving guider 5 is inclined plane structure, be oppositely arranged with the inclined-plane, side of the taper wedge 6 being arranged on lower die base 2 by bolt, for matching with the side ramp structure of taper wedge 6, guider 5 is driven to be arranged on the top of taper wedge 6, taper wedge 6 moves horizontally and is arranged in lower die base 2, the bottom of guider 5 is driven to lean on the inclined-plane, side of taper wedge 6 when matched moulds, and promote taper wedge 6 to move horizontally.The opposite side sloped roof of taper wedge 6 is in the bottom of flange cutter block mount pad 4, and by the power driving guider 5 to be applied to taper wedge 6, taper wedge 6 promotes flange cutter block mount pad 4 and moves up.Flange cutter block mount pad 4 is also provided with displacement transducer 10, displacement transducer 10 is connected with flange cutter block mount pad 4, for detecting the displaced position of flange cutter block mount pad 4, flange cutter block mount pad 4 is provided with flange cutter block 3 simultaneously, flange cutter block 3 is also provided with pressure sensor 11, pressure sensor 11 is connected with flange cutter block 3, can be real-time the pressure data that flange cutter block 3 is subject to detected, have very large assistance dissection to the displacement of flange cutter block 3, durability degree.Flange cutter block 3 is arranged on flange cutter block mount pad 4 by bolt and pin, and flange cutter block mount pad 4 is arranged in lower die base 2.Drive guider 5 just can promote flange cutter block 3 by taper wedge 6 when matched moulds upwards to push up; carry out flaps work; after completing; lower die base 2 is also provided with the backhaul air spring 7 be connected with taper wedge 6; make taper wedge 6 backhaul by backhaul air spring 7, thus reach the effect of backward flanging, this mould structure is simple; pressing direction is unified, and cost of manufacture is cheap.
In certain embodiments; the bottom of described taper wedge 6 is also provided with wearing plate 8; taper wedge 6 is moved horizontally by wearing plate 8 and is arranged in lower die base 2; the top of described driving guider 5 is provided with nitrogen spring 9; guider 5 is driven to be arranged in upper die base 1 by nitrogen spring 9; so move around by wearing plate 8; taper wedge 6 will become wear-resistant; long service life; drive guider 5 will have a buffer stage; with improving the compression strength driving guider 5, improve service life.
During use; upper/lower die carries out matched moulds; the driving guider 5 of upper die base 1 promotes taper wedge 6; and the flange cutter block 3 promoted on flange cutter block mount pad 4 carries out work simultaneously, after completing, make taper wedge 6 backhaul by backhaul air spring 7; thus reach the effect of backward flanging; by being arranged on the displacement transducer 10 of flange cutter block mount pad 4, whether display flange cutter block 3 is walked to put in place, and whether flange is complete.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent shapes or Structural Transformation; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
