Background technology
Large-sized bender is the class visual plant to large-scale sheet metal or plastic plate processing.Large-sized bender mould is generally made up of multiple little moulds, but all has some flexible deformations in the time of load or non-load, if mould is not carried out to flexible compensation, in the operating efficiency that will affect large-sized bender normal process flow process.Present stage, flexible compensation is generally rule of thumb regulated by workman, lacks concrete beasurement base, and can not reach enough precision.
summary of the invention
The object of the invention is to solve the problem that prior art exists, provide a kind of large-sized bender mould flexible compensation method, its method is simple and reliable, practical, and compensation precision is high, simple to operate, can greatly enhance productivity.
In order to realize above-mentioned purpose, the present invention realizes by following technical scheme:
The flexible compensation method of a kind of large-sized bender mould, is characterized in that comprising one group of foil gauge 1, and motor 2, carves type compensation block 3, counterdie 4, mold 5, mould connection strap 6, control module 7 etc., wherein motor 2 is made up of multiple separated motors, and mold 5 is made up of multiple little moulds.Described one group of foil gauge 1 linearity is put on mold 5, flexible deformation's amount of mould while work for measuring large-sized bender load; Between the little mould of mold 5, be bumped into mould connection strap 6, mould is not directly contacted with work piece, or linear contact, can be used for reducing the mould of large-sized bender in the time of work and occur being pressed from both sides and being scraped situation; The flexible deformation that described foil gauge 1 is measured measures result feedback to control module 7, motor 2 is under the adjusting of control module 7, the required rotational angle of each separated motor of accurate adjustment, each separated motor drive is carved accordingly type compensation block 3 and is moved, realization is carved type compensation block 3 to being inserted into the control of the amount of feeding of counterdie 4, makes counterdie 4 carry out flexible compensation accurately to mold 5.
Further, it is characterized in that: described one group of foil gauge 1 should adopt high-precision foil gauge, can ensure to realize accurately measuring mold 5 flexible deformations.
Further, it is characterized in that: described motor 2 adopts stepper motor, each separated motor should be high accuracy and regulates motor, can independently regulate rotational angle and can drive according to flexible deformation's needs and carve accordingly type compensation block 3 and move.
Further, it is characterized in that: described in carve type compensation block 3 and should there is enough rigidity, ensure can effectively regulate counterdie 4 after it is inserted into.
Further, it is characterized in that: in described mold 5, each little mould should closely splice, can suitably reduce the flexible deformation of mold 5.
Further, it is characterized in that: described mould connection strap 6 cross sections are mushroom, can reduce the contact response of mould connection strap 6 and work piece, and then improve the scratch resistant and anti-pinch effect of mold 5.
The beneficial effect that the present invention adopts technique scheme to reach is:
(1) reliability is strong, practical;
(2) compensation precision is high, and cost is low;
(3) easy to operate, enhance productivity.
