Problems solved by technology

However, the manual test takes a long time and requires the operator to have rich adjustment experience, which will affect the production efficiency of the automatic production line, and more sheets will be consumed in the process of the manual test (the sheet section used for the test will not be able to being directly utilized), resulting in waste of materials and increased production costs in a disguised form

Embodiment 1

[0030] Assuming that the width of the plate to be leveled is W, the thickness is T, and the yield limit is δs, the leveling machine is equipped with a first roller group adjustment device for adjusting the feeding gap D1 and a second roller group adjustment device for adjusting the discharging gap D2. Roller adjustment device. For fast and precise leveling of the sheet, the following steps can be implemented:

[0031] First, input the identification data of the sheet into the computer: width W, thickness T and yield limit δs to retrieve the empirical parameter values ​​for leveling of the corresponding sheet in the database. Such an empirical parameter value may be a set of data consisting of a value A and a value B, wherein the value A corresponds to the size of the feeding gap D1, and the value B corresponds to the size of the discharge gap D2.

[0032] Second, the computer reads the state value A' of the feed gap sensor used to measure the feed gap D1, and the state value ...

Embodiment 2

[0037] The numerical control leveling machine of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Such as figure 2 As shown, the CNC leveling machine of this embodiment consists of a frame 1, an upper leveling roller group 2, a lower leveling roller group 3, a first roller group adjustment device 4, a second roller group adjustment device 5, a first spring 6, and a second roller group adjustment device. Two springs 7, feed gap sensor 8, discharge gap sensor 9, first motor 10, second motor 11, PLC12 and computer 13 constitute.

[0039]Among them, the frame 1, the upper leveling roller group 2, the lower leveling roller group 3, the first roller group adjustment device 4, the second roller group adjustment device 5, the first spring 6, and the second spring 7 constitute the prior art. Leveling machine. The feeding gap D1 at the feeding end between the upper leveling roller group 2 and the lower level...

Embodiment 3

[0044] Such as image 3 As shown, the difference between this embodiment and Embodiment 2 is that: the feed gap sensor 8' and the discharge gap sensor 9' are installed vertically, rather than the oblique installation of Embodiment 2. The first motor 10' and the second motor 11' are variable frequency motors, the first motor 10' is connected to the corresponding port of the PLC12' through the first frequency converter 14; the second motor 11' is connected to the PLC12' through the second frequency converter 15 on the corresponding port.

[0045] The feeding gap sensor 8' is vertically installed, and the measured result is the length of the projection of the feeding gap D1 in the vertical direction. It is easy to know that there is a one-to-one correspondence between the length of the projection and the feeding gap D1. The above-mentioned projected length values ​​can then also be used as status values ​​for the feed gap sensor 8 ′.

Abstract

A numerical control leveling machine includes a frame, an upper leveling roller set, a lower leveling roller set, a first roller set adjustment device and a second roller set adjustment device; wherein the first roller set adjustment device is driven by a first motor, the second roller adjustment device is driven by a second motor, a feeding interval sensor for measuring a feeding interval D1 is arranged on a feeding end between the upper leveling roller set and the lower leveling roller set, and a discharging interval sensor for measuring a discharging interval D2 is arranged between the upper leveling roller set and the lower leveling roller set. The numerical control leveling machine also includes a control device storing an experience parameter value database. The feeding interval sensor, the discharging interval sensor, the first motor and the second motor are respectively communicated with corresponding ports of the control device. The feeding interval sensor and the discharging interval sensor are installed obliquely. The numerical control leveling machine of the invention is refitted based on the prior manual leveling machine, the refit cost is low, the debugging is simple, rapid, and accurate, and the use effect is notable.

Description

technical field [0001] The invention relates to a numerical control leveling method and a leveling machine for plate leveling. Background technique [0002] Before bending or slitting coiled sheet metal, it is usually necessary to level the sheet metal. The machine commonly used in the leveling process is a leveling machine, and its working principle is as follows: After the sheet is sent into the gap between the upper leveling roller group and the lower leveling roller group of the leveling machine, it will be pinched forward and moved forward During the process, the upper leveling roller group and the lower leveling roller group will repeatedly bend the sheet at the same time to eliminate its internal stress. Along the moving direction of the sheet, the upper and lower leveling rollers will repeatedly bend the sheet. The extent of the effect gradually weakens, and the sheet becomes smooth and smooth when it is finally output. [0003] Such as figure 1 As shown, each upp...
