Problems solved by technology

[0004] The present invention aims at the technical problems existing in the prior art, and provides a control device for preventing tower unloading, which mainly solves the technical problems existing in the prior art that are difficult to solve on site, and especially solves the problem that is easily generated during pickling unloading. The friction between the steel coil and the reel causes the phenomenon that the core is pulled to form a tower-shaped steel coil. The technology of the present invention can effectively integrate the functions of support, follow-up, and stability and ensure that the steel coil will not produce a tower-shaped coil. Rolling effect, while effectively controlling the quality of the strip steel plate, thus effectively improving the yield

Embodiment 1

[0032] Example 1: see Figure 1-Figure 5 , A control device for preventing tower-shaped unwinding, said control device comprising a support assembly, a pressing assembly and a following assembly, the support assembly comprising a guide roller bearing 5, a guide roller 6 and a tongue 10, the pressing assembly It includes a cylinder 3, a compression spring 4, a guide plate sliding groove 7, a pressure plate 8, and a connecting rod 9. The cylinder 3 piston rod head is fixedly connected to the connecting plate in the middle of the connecting rod 9 bracket by a nut, and the connecting rod 9 is threaded Connected to the pressure plate 8, a set of compression springs 4 are respectively provided on both sides of the pressure plate 8, a convex structure guide roller 6 is provided under the guide plate chute 7, and the guide roller 6 is provided on the guide roller bearing 5. The assembly includes an executive guide rod 12 and an oil cylinder 14. The synchronous action of the guide rod 1...

Embodiment 2

[0033] Example 2: see Figure 1-Figure 5 , A control method of a control device preventing tower unloading, the method is as follows:

[0034] 1) The strip steel is successfully coiled into a coil without overflow, and the expansion and contraction function of the coil is implemented;

[0035] 2) There is a 15mm gap between the reel and the steel coil after shrinking, and the anti-tower device is inserted at this time;

[0036] 3) The compression cylinder action implements the anti-tower device to compress the reel;

[0037] 4) The unloading action starts. During the unloading process, the anti-tower type device follows the unloading trolley to move and follow and press it in real time;

[0038] 5) The steel coil is stably discharged to the reel;

[0039] 6) The anti-tower device is retracted to prepare for the unloading of the next roll.

[0040] In the step 1), in order to ensure the quality of the coil shape when the strip is crimped, this unit adopts 9 CPC correction devices to contr...

Abstract

The invention discloses a control device for preventing tower-shaped coil discharging. The control device is characterized by comprising a supporting assembly, a pressing assembly and a following assembly, wherein the supporting assembly comprises guide roller bearings, a guide roller and a plug tongue, and the pressing assembly comprises an air cylinder, compression springs, a guide plate slidingchute, a pressing plate and a connecting rod; and the head of an air cylinder piston rod is fixedly connected to a connecting plate in the middle of a connecting rod support through a nut, the connecting rod is connected to the pressing plate through threads, the two sides of the pressing plate are correspondingly provided with the group of pressing springs, the guide roller with a middle-convextype structure is arranged below the guide plate sliding chute, and the guide roller is arranged on the guide roller bearings.

Description

Technical field [0001] The invention relates to a control device, in particular to a control device for preventing tower-shaped unloading, belonging to the technical field of cold rolling equipment. Background technique [0002] At present, most domestic and foreign pickling units generally use the control technology to improve the quality of the inner and outer edges of the coil after unloading the pickling plate, which is mostly to add a set of push rod mechanisms above or below the reel of the coiler. To ensure that the tower-shaped coil appears after the unloading action, although it has a smoothing effect on the outer circle of the steel coil, it also has obvious defects. In order to ensure the coil shape quality when the strip is crimped, this unit A 9-channel CPC correction device is used to control the operation center of the strip to coincide with the center line of the unit, and a steering pinch roller with a convex structure and a certain self-correcting ability is set...
