Abstract

The utility model relates to a prevent advanced high-strength steel from moving back unit and batch device of fish tail, including taking tail compression roller, support frame, pneumatic cylinder, take the tail compression roller to be connected with the piston rod of pneumatic cylinder, the pneumatic cylinder setting in the dolly both sides of unloading a roll, pneumatic cylinder and support frame fixed connection, the support frame is fixed on spool district civil engineering basis. The advantages are that: simple structure can install under the operating mode that does not change civil engineering foundation structure. The compression roller with the tail can be abutted against the steel coil under the driving of the hydraulic cylinder, the compression roller with the tail is in contact with the steel coil, and the defect that the outer diameter of a finished product of a continuous annealing line is scratched is effectively eliminated through a rolling mode. The pneumatic cylinder sets up in the dolly both sides of unloading, increases the position that compresses tightly of a tape tail compression roller, avoids producing sliding friction between last round of tape tail and the unloading car completely, and in addition, the tape tail compression roller that sets up in the dolly both sides of unloading still can play the effect of supporting the coil of strip simultaneously.

Description

Device for preventing advanced high-strength steel continuous annealing unit from coiling scratch

Technical Field

The utility model relates to a device for preventing batch fish tail defect especially relates to a device for preventing advanced high-strength steel continuous annealing unit batches the fish tail.

Background

In the normal production process of the continuous annealing unit, the finished coil is unloaded by lifting the unloading trolley before unloading, the unloading trolley rises under low pressure to jack up the steel coil, the strip tail of the steel coil is about one meter away from the preset position, and the coiling machine continues to rotate to the preset length of the strip tail and then starts to unload the coil. The main problem that this kind of mode coil stripping exists is, although the inside back surface quality of batching of whole roll steel sheet is good, nevertheless be exactly because produce sliding friction between the last circle of tape tail and the coil stripping car when coil stripping, consequently leave two meters about the outer lane of coil of strip and have the part of fish tail, especially to high strength steel product, because steel sheet intensity is higher, the head that sticks up appears easily when the outer lane relies on the dolly to push up tightly, lead to the outer lane can't tighten up, the coiler need continue to rotate and carry out the secondary and tighten up, aggravate the length and the severity of fish tail defect more. The coil stripping mode not only reduces the yield of products, but also causes the appearance of the steel coil to be unattractive, and causes dissatisfaction of the quality of users.

In the prior art, patent application No. 202120480049.7 discloses a hot rolled strip steel coiling guide device, which solves the problem that the existing equipment cannot perform good limiting on hot rolled strip steel when coiling the hot rolled strip steel. However, the device is suitable for the production process of hot rolled products, is not suitable for the coiling of cold rolled products, is in a motor driving mode, has the defect of large equipment installation space, and is not suitable for the requirement of installing the existing unit under the working condition that the civil engineering infrastructure is not changed.

Disclosure of Invention

For overcoming the not enough of prior art, the utility model aims at providing a prevent that advanced high strength steel from moving back the device that the unit batches the fish tail even, adopt the rolling mode contact coil of strip, effectively eliminate and move back even that the off-line finished product external diameter wipes the fish tail defect, improve product quality.

In order to achieve the above object, the utility model discloses a following technical scheme realizes:

the utility model provides a prevent advanced high strength steel continuous annealing unit from batching device of fish tail, includes area tail compression roller, support frame, pneumatic cylinder, takes the tail compression roller to be connected with the piston rod of pneumatic cylinder, the pneumatic cylinder setting in the dolly both sides of unloading a roll, pneumatic cylinder and support frame fixed connection, the support frame is fixed on reel district civil engineering basis.

The included angle between the central axis of the hydraulic cylinder and the vertical direction is 20-50 degrees.

The compression roller with the tail is connected with a piston rod of the hydraulic cylinder through a bearing.

Compared with the prior art, the beneficial effects of the utility model are that:

the device for preventing the coiling scratch of the advanced high-strength steel continuous annealing unit is simple in structure and can be installed under the working condition that the civil engineering foundation structure is not changed. The tape tail pressing roller can abut against the steel coil under the driving of the hydraulic cylinder, the tape tail pressing roller contacts the steel coil, and the defect that the outer diameter of a finished product is scratched when the tape tail is continuously withdrawn is effectively overcome through a rolling mode. The pneumatic cylinder sets up in the dolly both sides of unloading, increases the position that compresses tightly of two tape tail compression rollers, avoids producing sliding friction between last round of tape tail and the unloading car completely, and in addition, the tape tail compression roller that sets up in the dolly both sides of unloading still can play the effect of supporting the coil of strip simultaneously.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1-coil stripping trolley 2-tail press roll 3-steering roll 4-coil wrapper 5-hydraulic cylinder.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.

See fig. 1, a prevent advanced high-strength steel continuous annealing unit from batching device of fish tail, including taking tail compression roller 2, support frame, pneumatic cylinder 5, take tail compression roller 2 to be connected with the piston rod of pneumatic cylinder 5, pneumatic cylinder 5 sets up in 1 both sides of coil stripping dolly, can avoid producing sliding friction between the last round of tape tail and the coil stripping car like this, shortens the distance between tape tail head and the coil of strip simultaneously, avoids tape tail head to scrape equipment such as bump coil stripping car 1, wrapper aid 4. Pneumatic cylinder 5 and support frame fixed connection, the support frame is fixed on reel district civil engineering basis. The included angle between the central axis of the hydraulic cylinder 5 and the vertical direction is 20-50 degrees. The compression roller 2 with the tail is connected with a piston rod of the hydraulic cylinder 5 through a bearing.

When the hydraulic cylinder 5 is installed, the maximum outer diameter of the steel coil when the hydraulic cylinder is contracted to the waiting position is ensured not to interfere with the normal coiling of the unit, and the lifting and moving of the coil stripping trolley 1 are also avoided.

The steel coil is coiled by the steering roller 3, the coiling aid 4 assists in coiling, when coiling is about to be completed, when the number of remaining coiling meters is 10-15 meters, the hydraulic cylinder 5 drives the tape tail pressing roller 2 to ascend, after the tape tail pressing roller 2 contacts the steel coil, the tape tail pressing roller 2 passively rotates along with the steel coil, and the tape tail pressing roller 2 rotates along with the steel coil until coiling is completed, so that the tape tail is tightened. The coil stripping trolley 1 is lifted, and after the steel coil is lifted in place, the hydraulic cylinder 5 drives the belt tail compression roller 2 to descend to a waiting position.
