Torsion shaft bending machine system for compensating bending depth by using grating ruler

Abstract

The invention relates to the technical field of torsion shaft bending machine systems, in particular to a torsion shaft bending machine system for compensating bending depth by using a grating ruler, which comprises the following steps of: 1, mounting a grating ruler ruler on a sliding block; 2, after the grating ruler returns to the original position, setting the position direction of the grating ruler to be consistent with the position direction of the stop block, treading the slide block to press to the bottom (pressing to the stop block), and setting the current position of the grating ruler to be consistent with the Y-axis position (the stop block position); 3, giving a parameter h '= h + delta; 4, changing the angle compensation value delta to just fold out a set angle (such as 90 degrees), and meanwhile, storing the position L1 of the grating ruler at the moment; due to the fact that the compensation value is updated all the time, accumulated errors are eliminated, and influences caused by metal fatigue and abrasion are eliminated, the bending precision can be guaranteed when the bending machine continuously works for several hours, even several years and several months, it is guaranteed that under continuous work, the bending precision is high, one-time bending is in place, compensation time is saved, and machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of torsion-axis bending machine systems, in particular to a torsion-axis bending machine system that uses a grating ruler to compensate bending depth. Background technique [0002] The torsion axis synchronous bending machine is made of two oil cylinders installed on the left and right sides of the frame, which drives the slider to reciprocate up and down, and keeps the synchronization through the torsion axis to bend the plate and process the product. The lower mold is placed on the workbench, the upper mold is installed on the slider, and the slider is pressed down so that the workpiece plate placed between the upper and lower molds is bent and formed under the pressure of the upper and lower molds to form a bending angle. [0003] It is a semi-closed-loop bending machine, which is the positioning of the Y-axis servo control block (block installed inside or outside the two oil cylinders), and the oil cylin...

Problems solved by technology

However, the torsional axis bending machine with a grating ruler on the market only uses the grating ruler to measure the positions of the return point, shift point, clamping point, and pressure holding point, and does not use it for closed-loop compensation of the bending position. For this reason, The present invention proposes a torsion axis bending machine system that uses a grating ruler to compensate the bending depth to solve the above problems
