The invention discloses a kind of deflection compensating mechanism of bending machine, include mainly workbench, sliding block, strain transducer, mold, oil cylinder and proportioning valve composition.The deflection of cutter and workbench is acquired by strain transducer, collected deflection information generates instruction by processor processing, the instruction control cylinder movement that processor generates, and oil cylinder, which acts on workbench, to be made its protrusion appropriate and then play the role of compensation.Beneficial effects of the present invention are：Achieve the effect that accurately control deflection compensation by the real-time linkage of sensor and oil cylinder, improve work efficiency, avoid the cumbersome and inaccurate of manual debugging, improves the precision and qualification rate of work pieces process, it is simple in structure, it is easy for installation.
Description
Technical field
The present invention relates to processing machinery fields, are specifically related to a kind of deflection compensating mechanism of bending machine.
Background technology
Bender is a kind of common processing equipment, it applies convenient, processing efficiency especially in the process of thin plate
It is high.But due to cutter in process and mold unbalance stress, cutter will appear the deflection deformation being recessed upwards, and mold meeting
There is the deflection deformation to lower recess, especially this deflection deformation is more obvious when bender span is larger, to the essence of processing
Degree influences very big.Existing deflection compensation method generally use workbench adds convex in advance, and wedge block adds the methods of convex to work
Carry out advance deflection compensation as platform or simple adjust automatically can be carried out, and these methods cannot be satisfied it is increasing
The needs of different station deflection compensation when requirement on machining accuracy and multistation are processed.
Invention content
In order to solve the above technical problems, the present invention provides a kind of deflection compensating mechanism of bending machine.
A kind of deflection compensating mechanism of bending machine of the present invention, including sliding block, cutter, tool coupling, mold and bottom
Plate, the cutter are connected by the tool coupling with the sliding block, and the mold is fixed on the bottom plate, affiliated pedestal
Under the bottom plate；Characterized by further comprising strain transducer, upper protective shell, lower protective shell, oil cylinder, proportioning valve, pedestal,
Processor, conducting wire；Several described strain transducers are embedded in the both sides of the top of the cutter and the lower part of the mold
Outer surface, each sensor are connected with the conducting wire respectively, and the other end of the every conducting wire connects the processor；By
More in the type of existing strain transducer, application method is also not quite similar, can be by it by taking resistance strain sensor as an example
It is attached to the position for needing to monitor deformation, can be pasted by level shown in attached drawing also can be according to specific working environment and data processing
It needs to paste.
The upper protective shell is sleeved on the upper outside of the cutter, and the sensor is covered, and the upper protective shell passes through
Screw is connected with the sliding block；The lower protective shell is sleeved on the lower outside of the mold, the lower protective shell by screw with
The bottom plate is connected；The upper protective shell can be customized with lower protective shell by the size of cutter and mold, and should ensure that is not influencing knife
Strain transducer is closely covered in the case of the use of tool and mold as possible, makes strain transducer and extraneous severe building ring
Border is isolated.Protective shell is connected with sliding block and bottom plate by screw respectively, easy to disassemble, does not influence to replace cutter and to sensor
It is safeguarded.
The mold is fixed on the bottom plate, several oil cylinders are disposed vertically under the bottom plate, the oil cylinder
Top and the bottom plate perpendicular contact, each described oil cylinder is coupled there are one the proportioning valve and is used cooperatively, often
One proportioning valve is connected by the conducting wire with the processor, the lower part of each oil cylinder with the pedestal
Vertical connection.
The strain transducer incudes the deformation situation of the cutter and each point of the mold and in real time passes signal
It is defeated by the processor；The processor receive information handle after the signal of the strain transducer and dynamically to
Each proportioning valve sends out instruction；The pressure of each oil cylinder of each proportional valve control, makes each oil cylinder root
Different degrees of stretch is carried out according to the needs of deflection compensation.
By the real-time monitoring and processing to deformation signal, the deformation data of each position is collected, and then pass through oil
The flexible of cylinder applies external force to bottom plate, and cutter and the deformation quantity of mold is made mutually to compensate.
Beneficial effects of the present invention are：Reach the effect for accurately controlling deflection compensation by the real-time linkage of sensor and oil cylinder
Fruit improves work efficiency, and avoids the cumbersome and inaccurate of manual debugging, improves the precision and qualification rate of work pieces process, knot
Structure is simple, easy for installation.
Description of the drawings
In order that the present invention can be more clearly and readily understood, right below according to specific embodiment and in conjunction with attached drawing
The present invention is described in further detail.
Fig. 1 is a kind of structural schematic diagram of deflection compensating mechanism of bending machine.
Wherein：Protective shell, 7- under 1- sliding blocks, 2- cutters, 3- tool couplings, 4- strain transducers, the upper protective shells of 5-, 6-
Mold, 8- bottom plates, 9- oil cylinders, 10- proportioning valves, 11- pedestals, 12- processors, 13- conducting wires.
Specific implementation mode
As shown in Figure 1, a kind of deflection compensating mechanism of bending machine of the present invention, including the connection of sliding block 1, cutter 2, cutter
