Embodiment 1

[0056] Such as image 3 As shown, A is the normal bending condition, B is abnormal bending; among them, the upper mold 100 is the normal upper mold, and the upper mold 200 is the wrong upper mold installed by mistake, and the height of the upper mold 200 is 10mm longer than the upper mold 100 ; Set the working distance as 15mm; then set the load value of the upper die required in the fast-forward area to 3 tons, and then set the load value of the upper die required to bend workpieces 300 in the working area to 10 tons; determine the abnormal load of the upper die It means that in the fast-forward area, the current feedback actual die load value exceeds the preset upper die load value by more than 5 tons.

[0057] A: Under normal bending conditions, after the upper mold 100 enters the working area from the fast-forward area, the speed gradually decreases and enters the workpiece bending process. B is an abnormal bending situation. Since the upper die 200 is 10mm longer than th...

Embodiment 2

[0059] Such as image 3 As shown, A is the normal bending condition, B is abnormal bending; among them, the upper mold 100 is the normal upper mold, and the upper mold 200 is the wrong upper mold installed by mistake, and the height of the upper mold 200 is 10mm longer than the upper mold 100 ; Set the working distance as 15mm; set the load of the upper die required in the fast-forward area to be 3 tons, and then set the load of the upper die required to bend the workpiece in the working area to be 5 tons; the condition for determining the abnormal load of the upper die is The current feedback in the entering area is that the actual die load value exceeds the preset upper die load value by more than 5 tons.

[0060] B is an abnormal bending situation. Since the upper mold 200 is 10mm longer than the height of the upper mold 100, the upper mold 200 bends the workpiece 300 in advance in the fast-forward zone. At this time, the servo drive detects that the actual mold load value ...

Embodiment 3

[0062] Such as Figure 4 As shown, A is the normal bending condition, B is the abnormal bending condition; the upper mold 101 is the normal upper mold, and the upper mold 201 is the wrong upper mold installed by mistake; the upper mold 201 is 20mm longer than the vertical effective dimension of the upper mold 101 , set the working distance as 15mm, that is, the upper mold 201, the workpiece 301 and the lower mold 401 have been completely crushed to death in the fast-forward area; Bending workpiece 301 requires a load value of 5 tons on the upper die; the determination condition for the abnormal load of the upper die is that the current feedback in the fast-forward zone is that the actual die load value exceeds the preset upper die load value by more than 5 tons, then the folded value in the second embodiment Bend abnormality judgment is a failure condition.

[0063] Then in the fast-forward area, the upper mold 201 presses down the workpiece 301 and gradually approaches the V...

Abstract

The invention discloses an all-electric servo numerical-control bending machine with an upper die load monitoring and protecting device. A rapid feeding area and a work feeding area are included. The bending machine comprises a machine frame body, a numerical-control system, a servo system, a speed reducer, a synchronous wheel mechanism, a ball screw, a sliding block, an upper die, a lower die and a displacement sensor. The displacement sensor is arranged on one side of the sliding block and used for measuring the actual positions of the sliding block and / or the upper die. The all-electric servo numerical-control bending machine with the upper die load monitoring and protecting device has the beneficial effects that the defects that according to an existing all-electric servo numerical-control bending machine, the output bending force of an upper die cannot be limited in the work feeding area, the stress and movement conditions of the upper die cannot be monitored in the rapid feeding area, and stopping and alarming cannot be achieved under the condition that the upper die operates abnormally are overcome.

Description

technical field [0001] The invention relates to the technical field of numerical control bending machines, in particular to an all-electric servo numerical control bending machine with an upper die load monitoring and protection device, and a method for monitoring and protecting the upper die load of the bending machine. Background technique [0002] The main difference between the all-electric servo CNC bending machine and the general hydraulic CNC bending machine is that all motion axes are controlled by components such as electric servo motors and rolling screws, the hydraulic system is cancelled, and hydraulic oil is not used. [0003] At present, all-electric servo CNC bending machines on the market cannot limit the output bending force of the upper die in the work-in area and cannot monitor the force and movement of the upper die in the fast-forward area, and cannot protect the upper and lower dies. [0004] Specifically, the downward bending process is divided into a ...
