Description

Steel coil inner ring clamp

Technical Field

The utility model belongs to the technical field of cold-rolled steel coil production technique and specifically relates to an auxiliary fixtures for pressing from both sides tight coil of strip inner circle.

Background

The cold-rolled steel coil of the heavy-coil withdrawal straightening unit production line in the finishing workshop of the cold rolling factory, particularly the steel coil with the thickness specification less than or equal to 1.0 mm, has the defect of loose inner ring under most conditions, and is mainly characterized in that the inner ring collapses under the self weight of the steel coil to be loose due to the small tension of the relatively thin steel strip inner ring. The defects often cause the accidents that the cold-rolled steel coil cannot smoothly enter the mandrel of the uncoiler in the production process of the uncoiler, the inner ring of the steel coil is ejected out, and the rubber sleeve of the mandrel of the uncoiler is damaged, the blocking problem of the on-line production of the cold-rolled steel coil is high, and the production efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a coil of strip inner circle anchor clamps, this kind of anchor clamps can solve the cold-rolled coil of strip that current thickness is less than 1mm and go up the production and have the loose problem of inner circle of appearing easily.

In order to solve the problem, the utility model discloses a technical scheme be: this kind of coil of strip inner circle anchor clamps is including shearing into parallelogram's cold rolled coil of strip tie, form the anchor clamps body after the cold rolled coil of strip tie centering is bent and is hammered into, in the coil of strip is hammered into along the axial to the anchor clamps body, the chucking has 3 ~ 4 layers between two clamping pieces of anchor clamps body the coil of strip, one of them the clamping piece with the surface that exposes of the inner circle first layer of coil of strip closely laminates, the anchor clamps body with leave between the tape head of the inner circle first layer and be equipped with one section distance.

In the technical scheme of the steel coil inner ring clamp, a more specific technical scheme can also be as follows: the thickness of the cold-rolled steel coil binding belt is less than 1 mm.

Further, the thickness of the cold-rolled steel coil binding belt is 0.9 mm.

Further, the clamp body is clamped at the position, 300mm away from the belt head, of the first layer of the inner ring.

Further, the width of the cold-rolled steel coil binding band is 30 mm.

Further, the total length of the cold-rolled steel coil binding belt is 200 mm.

Furthermore, the diagonal angles of the two ends of the cold-rolled steel coil binding belt are 45 degrees.

Further, the clamp body is made of steel materials with the grade FD-2.

Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has:

1. the structure is simple, the cost is low, the reliability is high, the raw material source is wide, and the manufacture is relatively simple; the clamp for clamping the inner ring of the steel coil can be formed after the cold-rolled steel coil is cut into the parallelogram and folded and hammered, the clamp is hammered into the steel coil to be clamped for 3-4 layers, so that loosening of the inner ring can be effectively avoided, the steel coil inner ring can normally enter a mandrel of the uncoiler, the blocking fault of line production on the cold-rolled steel coil can be effectively reduced, the damage of a rubber sleeve of the uncoiler is prevented, and the production efficiency is improved.

2. The thickness, the width, the length and the clamping position of the cold-rolled steel coil bundling belt for manufacturing the clamp body are limited, so that the clamping force of the clamp body can be ensured, the inner ring of the steel coil is not loose in the moving process, and meanwhile, the clamp cannot move in the moving process of the steel coil and cannot block the steel coil entering an uncoiler.

3. The 45-degree oblique angle at the end part of the clamp body is convenient to shear and easy to insert into a steel coil.

4. The steel used by the clamp body has high strength, good wear resistance and long service life, and can be repeatedly used.

Detailed Description

Through repeated observation and analysis, continuous practice and exploration, continuous summary of processing experience and optimization of processing methods in actual production work, the applicant designs and manufactures a special clamp aiming at loosening of the inner ring of the cold-rolled steel coil, and the special clamp is further detailed in the following embodiment with the attached drawings:

the raw materials of the steel coil inner ring clamp shown in fig. 1 to 5 are cold rolled steel coil bundling belts which are used in a waste mode, the cold rolled steel coil bundling belts are made of steel materials with the brand number FD-2, the thickness of the cold rolled steel coil bundling belts is smaller than 1mm, and steel coil packing belts made of other steel materials can be adopted in other embodiments. The cold-rolled steel coil binding belt is cut into a parallelogram by using a wire shear, the total length L of the formed cold-rolled steel coil binding belt is 200mm, the width W of the cold-rolled steel coil binding belt is 30mm, the thickness H of the cold-rolled steel coil binding belt is 0.9mm, the opposite angles of the two ends of the cold-rolled steel coil binding belt are 45 degrees, the cold-rolled steel coil binding belt formed by shearing is bent in a centering way and is hammered by an iron hammer to form a clamp body, and the two clamping pieces of the clamp body are arranged in parallel.

When the clamp is used, firstly, a loose belt head of the inner ring of the cold-rolled steel coil is manually and clockwise compressed, the inner ring of the cold-rolled steel coil with loose strip steel is ensured to be tightly attached, the position, which is about 300mm away from the belt head, of the first layer of the inner ring of the steel coil is provided with a clamping piece of the clamp body, which is axially inserted into the inner ring of the steel coil with the solid steel coil along the steel coil and is about 3-4 layers of the inner ring steel coil, and the other clamping piece of the clamp body is tightly attached to the exposed surface of the first layer of the inner ring of the steel coil, then, the clamp is hammered into the steel coil by using an iron hammer, the tension of the clamp is repeatedly utilized, 3-4 layers of steel coils of the inner ring of the steel coil are tightly clamped between the two clamping pieces of the clamp body, the steel coil is clamped by the clamp body, and the inner ring of the clamp is collapsed to obtain very effective treatment. When the clamped steel coil is produced on line, the steel coil can smoothly enter the mandrel of the uncoiler, the production efficiency is much higher than that of the clamp which is not used, and the problems that the raw steel coil is ejected out and the rubber sleeve of the uncoiler is damaged in the process of entering the mandrel of the uncoiler are reduced. In addition, the clamp has the advantages of low cost, high reliability, simplicity, convenience, practicability and the like. The steel coil inner ring clamp is already put into daily production practice of the applicant in a large amount, unnecessary downtime in the production process is reduced until the steel coil inner ring clamp is put into production and use, and production efficiency and economic benefits are improved.
