Description

Technical Field

[0001] The present invention belongs to the technical field of steel ring coiling processing, and more specifically, relates to a steel ring coiling and packing adjusting device and an adjusting method. Background Art

[0002] Rolled steel coils are continuously operated both in their production process and in the process of using them to produce other products. They are produced and used in batches in units of rolls, so they all include a continuous winding process. However, in current actual production, it is found that due to the edge electrostatic effect of metals, for rolled steel coils, during the continuous winding process, the edges of the steel strips at the winding end are prone to serious edge warping and curling phenomena, resulting in the product quality not meeting the requirements.

[0003] After retrieval, such as the Chinese patent publication number: CN201848444U, the invention creation name is: a thin copper strip winding device, including components such as a frame, an electric control box, and a tensioning shaft; the electric control box, the tensioning shaft and other components are installed on the frame; the electric control box is connected to the tensioning shaft component, and the electric control instrument on the electric control box can display the counted winding turns, display the frequency modulation frequency of the winding motor, and control the constant linear speed of the thin copper strip being wound. The electric control box contains a turn encoder that measures the length of the wound copper strip and can give a signal according to a set value. By controlling the linear speed of the thin copper strip being wound through the electric control box and adjusting the winding tension of the copper strip during the winding process, the friction force obtained by the copper strip during winding is made uniform, so that it does not deviate during the winding process, thus solving the problem of edge warping and curling during the copper strip winding process. This solution is a beneficial research on solving the problem of edge warping and curling of steel coils, but there is still room for further improvement. After all, when adjusting for relatively thick steel coils, the strength is relatively large, and it is very difficult for this solution to solve the serious edge warping and curling phenomena of the steel strip edges. The industry's research on solving such problems has never stopped. Summary of the Invention

[0004] 1. Technical Problems to be Solved by the Invention

[0005] Aiming at the problem that steel coils are prone to edge warping and curling during the coiling process of steel rings in the prior art, the present invention provides a steel ring coiling and packing adjusting device and an adjusting method. By forming an annular stepped tensioning platform with a conical base and split tensioning pieces that are slidably matched, the edge warping and curling of the steel coil are adjusted accordingly, and thus the purpose of high-strength tensioning adjustment is achieved.

[0006] 2. Technical Solutions

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A steel coil rolling and packaging adjustment device of the present invention comprises a frustum-shaped base and a plurality of arc-shaped tensioning plates slidably connected to the conical surface of the base, wherein the plurality of tensioning plates are generally symmetrically or evenly arranged; the axis of the base is a vertical center hole, and the outer arc surface of the tensioning plates forms an annular stepped tensioning platform to facilitate the steel coil to be sleeved on the tensioning platform.

[0009] As a further improvement of the present invention, a slope-shaped slide groove is evenly and fixedly connected on the outer conical surface of the base, and a slide rail matching the slide groove is arranged on the inner side of the sub-tensioning plate. The number of the slide grooves is consistent with the number of sub-tensioning plates. When the base slides on the slide rail, a tensioning process of the steel coil is formed, which saves labor in operation and has high strength for adjusting the warping and curling of the steel coil.

[0010] As a further improvement of the present invention, there are more than two tensioning platforms to form multi-stage adjustment, generally two or three stages or more to cope with steel coils of different diameters.

[0011] As a further improvement of the present invention, a clamping platform and a clamping slot are respectively arranged on both sides of the tensioning plate. The clamping platform and the clamping slot of one tensioning plate are arranged in coordination with the clamping platform and the clamping slot of the other tensioning plate, and can be clamped together before the tensioning work is done to avoid up and down movement before tensioning and affecting the tensioning adjustment.

[0012] As a further improvement of the present invention, the cross section of the slide groove is T-shaped, and the cross section of the corresponding slide rail is also T-shaped, which can not only slide but also buckle the slide groove and the slide rail, and can also improve the tension strength.

[0013] As a further improvement of the present invention, the inner surface of the slide rail is provided with criss-cross oil grooves, which may be in the shape of a Chinese character "丰" or a Chinese character "井". The tensioning plate is horizontally perforated with oil filling holes connected to the oil grooves, which serves to lubricate the slide rail and make operation more labor-saving.

[0014] As a further improvement of the present invention, it also includes a central axis; a key pin is embedded in the upper part of the central axis; a key slot is reserved in the central hole to match the key pin to prevent the central axis from rotating relative to the central hole during the tightening process, and the base is driven to move on the slide rail through the central axis to improve the tightening strength.

[0015] As a further improvement of the present invention, a positioning blind hole is reserved on the upper part of the central axis, and the cavity on the base has a positioning hole whose shape and size match the positioning blind hole. Before the tightening work, the positioning blind hole and the positioning hole are connected by a positioning pin to prevent the central axis from moving up and down during the tightening process.

[0016] A method for adjusting a steel ring rolling and packing adjustment device, comprising the following steps:

[0017] Step 1: Insert the central shaft into the central hole, insert the key pin along the keyway; connect the positioning blind hole and the positioning hole through the positioning pin; push the slide rails of each split tensioning piece up or down along the corresponding sliding grooves on the base until the clamping platforms and clamping grooves of one split tensioning piece are engaged with those of another split tensioning piece, and then the outer arc surfaces of the split tensioning pieces form an annular stepped tensioning platform;

[0018] Step 2: Put the steel coil on the annular stepped tensioning platform;

[0019] Step 3: Push the central shaft forward. As the engaged clamping platforms and clamping grooves are slowly separated, the curled or flanged coil is tensioned and adjusted to a flat state.

[0022] (1) For the steel coil rounding and packing adjusting device of the present invention, the steel coil is put on the annular stepped tensioning platform formed by the outer arc surfaces of multiple split tensioning pieces, and then tensioned through the sliding fit between the conical base and the split tensioning pieces, and the curled or flanged part of the steel coil is tensioned and adjusted accordingly, which is different from the strut type tensioning, and thus achieves the technical effect of high-strength tensioning adjustment;

[0023] (2) For the steel coil rounding and packing adjusting device of the present invention, there are more than 2 tensioning platforms, forming a multi-stage adjustment, generally two-stage or more than three-stage to cope with steel coils of different diameters, and it has strong versatility;
