Description

Bender system capable of stopping backwards and forwards automatically during step changing

Technical Field

The invention relates to the technical field of bending machines, in particular to a bending machine system with a rear material stop automatically stopping forwards during step changing.

Background

The bending machine is used for bending a metal plate in a cold state into workpieces with various geometric cross-sectional shapes by utilizing an equipped die (a general or special die), a special numerical control system for the bending machine is generally adopted, the coordinate axis of the bending machine is developed from a single axis to 12 axes, the numerical control system can automatically realize slide block operation depth control, slide block left-right inclination adjustment, back material stopper front-back adjustment, left-right adjustment, pressure tonnage adjustment, slide block approximate working speed adjustment and the like, the bending machine can conveniently realize actions of downward movement, inching, continuity, pressure maintaining, return stroke, midway stopping and the like of a slide block, and multi-elbow bending with the same angle or different angles can be completed by one-time feeding.

Many existing bending machines are lack of Z-axis configuration, when plates with different widths are folded, the bending machines need to walk behind the bending machines, the bending machines need to shift the Z1 and the Z2 axes by hands to enable the plates to move to the corresponding positions left/right, and in order to save time, some workers directly move in front of the bending machines, the hands extend between an upper die and a lower die to shift the Z axes, so that potential safety hazards are caused. Bending again, this mode needs twice click the button on the operating panel, wastes time and energy, and machining efficiency is low.

Disclosure of Invention

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a bender system that automatic forward berth of back dam when stepping, includes following step:

s1, adding a parameter into each step of parameters to form 'back stock stop forward stop';

s2, stepping on or maintaining the pressure to complete the automatic return of the slide block to the top dead center;

s3, starting START or bending to finish step changing, and reading the parameters of the step;

s4, judging a setting value of 'stopping the rear material forwards' and directly positioning the rear material to a set position (namely 'stopping forwards' and returning 0) in the step when the setting value is 0, if the height of the slide block is less than the required height of the stopping, stopping forwards and prompting a return stroke, stepping on the return stroke to a certain height, if the height of the slide block is more than or equal to the required height of the stopping, automatically extending the rear material to stop forwards ('stopping' 1), manually dialing the Z axis to a corresponding position, returning the rear material to the set position (namely 'stopping forwards' and returning 0), shielding a soft limit alarm when the rear material stops forwards and returns, and enabling the soft limit to be effective;

s5, the forward stop is 0, and the back stock stop is positioned and can be bent;

and S6, completing bending and pressure maintaining, and repeating the steps S2-S5.

Preferably, in S1, the settable value of "the back stock stop forward stops" is 0 or 1, when 0, it indicates not stopping forward, when 1, it indicates stopping forward, when the settable value is 1, it is determined whether the set value of the return height is greater than the height required for stopping, and if not, it is not allowed to set 1 and prompt.

Compared with the prior art, the bending machine system with the rear material blocking automatically stopping forwards during step changing is characterized in that the rear material blocking is judged according to different set values of the rear material blocking forwards stopping, so that plates with different bending widths are automatically positioned, the rear material blocking automatically extends out and stops, and automatically returns to a set position after the Z-axis position is shifted, and a button on an operation panel is not required to be pressed again during continuous bending, so that time and labor are saved, and the processing efficiency is improved.

FIG. 1 is a schematic flow chart of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1, in each step parameter, a parameter is added, namely 'back stock stop forward stopping', stepping on or maintaining pressure to finish automatic return stroke of the slide block to a top dead center, START or bending to finish step change, reading the parameter, judging a set value of 'back stock stop forward stopping', when the value is 0, the back stock stop is directly positioned to a set position of the step ('forward stopping' return 0), when the value is 1, if the height of the slide block is less than the required height of stopping, the slide block does not stop forward, and the return stroke is prompted, stepping on the return stroke to a certain height, if the height of the slide block is more than or equal to the required height of stopping, the back stock stop automatically extends forward to stop ('forward stopping' 1), manually dialing a Z axis to a corresponding position, stepping down, the back stock stop returns to the set position ('forward stopping' return 0), and the back stock stop goes out of a soft limit range due to forward stopping, at this moment, shielding a soft limit alarm, when the 'forward parking' is reset, the soft limit is effective, when the 'forward parking' is 0, the rear material stopping positioning is finished, the bending and the pressure maintaining are finished, and the steps from S2 to S5 are repeated.

Wherein, the settable value of "the back stock stop is parked forward" in S1 is 0 or 1, and when 0, it means not parking forward, and when 1, it means parking forward, and when the settable value is set to 1, it is judged whether the setting value of the return height is greater than the height required for parking, and if not, it is not allowed to set 1 and prompt.

In conclusion, the invention judges through different setting values of 'the rear material blocking is stopped forwards', so that the rear material blocking is automatically positioned when bending plates with different widths, the rear material blocking is automatically extended to stop, and automatically returns to the set position after shifting the Z-axis position, and when continuously bending, a button on an operation panel is not required to be pressed again, thereby saving time and labor and improving the processing efficiency.
