Problems solved by technology

[0005] The embodiment of the present invention provides a detection method for the expansion and contraction of the shaft of the coiler of the recoiling unit, which solves the problem that in the prior art, the diameter of the coiler occasionally shrinks during the working process and cannot be detected in time As a result, collapse occurs, resulting in the failure of unloading the strip normally, damaging the sleeve, degrading the product quality, and causing certain economic losses. The real-time monitoring of the diameter of the shaft of the coiler expands and shrinks to ensure that the strip Steel coils are unloaded normally, avoiding the technical effect of economic loss

Embodiment 1

[0037] The embodiment of the present application provides a method for detecting the expansion and contraction of the coiler shaft of the recoiling unit. figure 1 It is a schematic flowchart of a method for detecting the expansion and contraction of the coiler shaft of the recoiling unit in the embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0038] Step 110: Obtain the lateral movement size information of the hydraulic cylinder of the coiler;

[0039] Specifically, the coiler shaft is the main equipment responsible for coiling the steel strip into coils. The expansion and contraction control of the coiler shaft is the key to whether the finished steel coils can be coiled and unloaded normally. When the coiler coils thick-gauge strip steel, the load on the mandrel is too large, which may cause the phenomenon that the mandrel cannot be expanded, that is, the diameter of the mandrel shrinks, which makes it impossible to unload the coil nor...

Abstract

The invention provides a method for detecting expansion and shrinkage of a mandrel of a recoiling unit coiling machine. The method and the device relate to the technical field of electrical detection,and are applied to the recoiling unit coiling machine comprising a displacement sensor and an encoder. The method comprises the steps of: acquiring transverse moving size information of a hydraulic cylinder of the coiling machine; acquiring mandrel diameter expansion and shrinkage size information of the coiling machine according to the transverse moving size information; and determining whethera steel coil can be unloaded normally according to the mandrel diameter expansion and shrinkage size information. The method and the device solve the technical problems that the steel coil cannot be unloaded normally, a sleeve is damaged, the product quality is degraded and certain economic loss is caused due to coil collapsing because a diameter shrinkage situation accidentally occurs on the coiling machine in the operation process and cannot be detected timely, and achieve the technical effects of monitoring the mandrel diameter expansion and shrinkage size dimension of the coiling machine in real time, ensuring normal unloading of the steel coil and avoiding economic loss.

Description

technical field [0001] The invention relates to the technical field of electrical detection, in particular to a method and device for detecting expansion and contraction of a coiler shaft of a recoiling unit. Background technique [0002] The coiler is used to collect extra-long rolled parts and wind them into rolls for easy production, transportation and storage. The coiler is an important auxiliary equipment in the steel rolling workshop and an indispensable equipment in the coil rolling main rolling line. It is widely used in the production of strip and wire. The practice of steel rolling production has proved that ensuring the smooth operation of the coiler is of great significance to improving the production efficiency of the rolling mill. [0003] However, in the process of implementing the technical solutions in the embodiments of the present application, the applicant of the present invention found that the above-mentioned prior art has at least the following techni...
