Technical field
The present invention relates to bender, belong to the metal forming machinery field in mechanical engineering.More specifically, refer to that one kind is large-scale
Bender is in mould flexibility compensation method during loaded-up condition.
Background technology
Large-sized bender is the class visual plant to band large-scale metal sheet material or plastic plate processing.Large-sized bender mould
Typically it is made up of multiple little moulds, but all have some flexible deformations in load or non-load, if do not carried out to mould
Flexible compensation, in the operating efficiency that will affect large-sized bender normal process flow process.At this stage, flexible compensation is typically by workman
Rule of thumb adjust, lack specific beasurement base, and enough precision can not be reached.
Content of the invention
It is an object of the invention to solving the problems, such as prior art, there is provided a kind of large-sized bender mould is flexible
Compensation method, its method is simple and reliable, practical, and compensation precision is high, simple to operate, is greatly improved production efficiency.
In order to enable above-mentioned purpose, the present invention presses technical scheme below and realizes：
A kind of large-sized bender mould carves type with flexible compensation method it is characterised in that including one group of foil gauge 1, motor 2
Compensation block 3, lower mould 4, mold 5, mould connection strap 6, control module 7 etc., wherein motor 2 are made up of multiple separated motors, upper mould
Tool 5 is made up of multiple little moulds.Described one group of foil gauge 1 linearly arranges on mold 5, for measuring large-sized bender load
Flexible deformation's amount of mould during work；Be bumped into mould connection strap 6 between the little mould of mold 5 so that mould with processed
Part is not directly contacted with, or linear contact, can be used for reduction large-sized bender mould operationally and occurs being pressed from both sides and by the situation of scraping；
Flexible deformation's amount result of described foil gauge 1 measurement feeds back to control module 7, motor 2 under the regulation of control module 7, accurately
Adjust rotational angle needed for each separated motor, the drive of each separated motor is carved type compensation block 3 accordingly and moved, realize carving type compensation block
The control of 3 pairs of amount of feeding being inserted into lower mould 4, makes lower mould 4 that mold 5 is carried out with accurately flexible compensation.
Further it is characterised in that：Described one group of foil gauge 1 should adopt high-precision foil gauge, ensure that realize right
Mold 5 flexible deformation accurately measures.
Further it is characterised in that：Described motor 2 adopts stepper motor, and each separated motor should be high accuracy and adjusts electricity
Machine, with separately adjustable rotational angle and can can drive and carve type compensation block 3 accordingly and move according to the needs of flexible deformation.
Further it is characterised in that：Described carve type compensation block 3 should have enough rigidity it is ensured that its be inserted into after can under
Mould 4 is adjusted effectively.
Further it is characterised in that：In described mold 5, each little mould should closely splice, and can suitably reduce mold 5
Flexible deformation.
Further it is characterised in that：Described mould connection strap 6 section is in mushroom, can reduce mould connection strap 6 and be added
The contact response of workpiece, and then improve the scratch resistant and anti-pinch effect of mold 5.
The present invention using the beneficial effect that technique scheme can reach is：

Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail：
As shown in Fig. 1 ~ 3, the present invention is a kind of large-sized bender mould flexibility compensation method it is characterised in that including one
Group foil gauge 1, motor 2, carve type compensation block 3, lower mould 4, mold 5, mould connection strap 6, control module 7 etc., wherein motor 2 by
Multiple separated motor compositions, mold 5 is made up of multiple little moulds.First, between large-sized bender mold 5 is by multiple little moulds
Be spliced, needing to be bumped into a cross sectional shape between little mould is in mushroom-shaped mould connection strap 6, it is possible to reduce mould with
Folder that the contact of work piece is led to and scraping.According to actual conditions, select suitable foil gauge quantity and its required installation
Position, after foil gauge is linearly installed on mold 5, the test result according to foil gauge 1 can obtain flexible produced by mold 5
Deformation, the data obtained is fed back in control module 7, and control module 7, according to the data obtained, accurately adjusts each point in motor 2
Rotational angle needed for motor, the drive of each separated motor is carved type compensation block 3 accordingly and is moved and then the high-precision control amount of feeding, under
