[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0029] like Figure 1 , Figure 2 As shown, Figure 1 A schematic flow chart of a solution to the inner ring collapse of a sleeveless steel coil provided in an embodiment of the present application, Figure 2 This is a schematic diagram of the operation of a sleeveless steel coil provided in an embodiment of the present application.

[0030] A solution to the inner ring core collapse of a sleeveless steel coil 100, the solution comprising:

[0031] After the inner ring of the sleeveless steel coil 100 collapses, the loose inner ring strip steel is reset;

[0032] Take an auxiliary member 200, the auxiliary member 200 comprises a first section 201, a bending section 202 and a second section 203 connected in sequence, the first section 201 and the second section 203 are arranged opposite to each other, and the first section 201, the bending section 202 and the second section 203 enclose a holding space;

[0033] The first section 201 of the auxiliary member 200 is inserted between adjacent winding layers in the steel coil 100, and the second section 203 extends into the inner circle of the steel coil 100, so that the strip steel between the first section 201 and the second section 203 is located in the clamping space;

[0034] The auxiliary component 200 is operated to move along the axial direction of the steel coil 100 until the bending section 202 contacts the end surface of the steel coil 100 .

[0035] like Figure 1 , Figure 2 as well as Figure 3 As shown, Figure 3The schematic diagram of the auxiliary component 200 structure provided in the embodiment of the present application, in an optional implementation manner, the working principle of the solution in the present application is: when the method is used, it is first performed when the inner ring of the sleeveless steel coil 100 has a collapsed core, after the inner ring of the sleeveless steel coil 100 has a collapsed core, the loose inner ring strip steel is first reset, and then the auxiliary component 200 is taken out, the auxiliary component 200 includes a first section 201, a bending section 202 and a second section 203 connected in sequence, the first section 201 and the second section 203 are arranged opposite to each other, and the first section 201, the bending section 202 and the second section 203 are enclosed to form a holding space, and the first section 201 of the auxiliary component 200 is inserted Between adjacent winding layers in the steel coil 100, the second section 203 extends into the inner ring of the steel coil 100, so that the strip steel between the first section 201 and the second section 203 is located in the clamping space, and then the auxiliary component 200 is operated to move along the axial direction of the steel coil 100 until the bending section 202 contacts the end face of the steel coil 100. In this state, the problem of core collapse in the inner ring of the uncased steel coil 100 is solved, and a stable state is provided for coiling operations, avoiding extrusion deformation at the inner ring, improving the operating safety of operators, and quickly solving and processing when the inner ring core collapse occurs, so as to keep the processing operation stable and continuous, and improve production efficiency.

[0036] like Figure 1 , Figure 2 as well as Figure 3 As shown, in an optional embodiment, the length of the bending section 202 is an integer multiple of the thickness of the strip steel in the steel coil 100. By matching the length of the bending section 202 with the thickness of the strip steel, the first section 201 of the auxiliary component 200 is inserted between adjacent winding layers in the steel coil 100, and the second section 203 extends into the inner circle of the steel coil 100, until the strip steel between the first section 201 and the second section 203 is located in the holding space, and the length of the bending section 202 matches the thickness of the strip steel located in the holding space. To prevent the edge of the strip in the clamping space from being pushed against the first section 201 and the second section 203, after the first section 201 extends between adjacent winding layers in the steel coil 100, since the length of the bending section 202 does not match the thickness of the strip, the first section 201 is tilted and inserted between adjacent winding layers, which causes the first section 201 to push out a certain gap between adjacent winding layers, thereby reducing the consistency of the steel coil 100. By controlling the length of the bending section 202, it is possible to prevent the first section 201 from pushing out the gap between adjacent winding layers, thereby preventing deformation of the strip.

[0037] like Figure 1 , Figure 2 as well as Figure 3As shown, in an optional embodiment, the angle between the first section 201 and / or the second section 203 and the bending section 202 is an acute angle. When the first section 201 is inserted between adjacent winding layers in the steel coil 100 and the second section 203 extends into the inner circle of the steel coil 100, the end of the second section 203 away from the bending section 202 is pressed on the inner circle of the steel coil 100. On the one hand, a certain number of layers of strip steel are clamped by the first section 201 and the second section 203 to maintain the operating reliability of the auxiliary component 200, avoid relative slippage of the auxiliary component 200, and improve operating stability. On the other hand, the first section 201 and the second section 203 respectively occupy a smaller space to maintain stable winding and other operations of the steel coil 100.

[0038] like Figure 1 , Figure 2 as well as Figure 3 As shown, in an optional embodiment, the auxiliary component 200 has a deformation recovery force, so that the second section 203 is deformed and always remains pressed on the inner ring of the steel coil 100, and the deformation is restored after the second section 203 is separated from the steel coil 100.

[0039] The auxiliary part 200 has a certain deformation recovery force. When the auxiliary part 200 is not arranged on the steel coil 100, the clamping space between the first section 201 and the second section 203 on the auxiliary part 200 is in an initial state. When operation is required, the first section 201 and / or the second section 203 undergo a certain deformation, so that the clamping space is switched to a state that can accommodate a target amount of strip steel, thereby keeping the first section 201 and / or the second section 203 stable in relative position with the steel coil 100 under the deformation force, and restoring the deformation after the second section 203 is separated from the steel coil 100, so that the auxiliary part 200 can be arranged repeatedly and cyclically, with strong flexibility.

[0040] like Figure 1 , Figure 2 as well as Figure 3 As shown, in an optional embodiment, when the auxiliary component 200 is operated to move along the axial direction of the steel coil 100, pressure is applied to the bending section 202 in the axial direction of the steel coil 100 to reduce the difficulty of operation, and by applying a driving force through the bending section 202, the first section 201 and the second section 203 can be evenly driven to move respectively.

[0041] like Figure 3 as well as Figure 4 As shown, Figure 4A side view of the auxiliary component 200 provided in an embodiment of the present application, in an optional embodiment, a deflection angle is provided between the first section 201 and the second section 203, so that the mutual projections between the first section 201 and the second section 203 have overlapping parts and non-overlapping parts 204, and when operating the first section 201 to be inserted between adjacent winding layers in the steel coil 100, the non-overlapping part 204 is gripped, and the non-overlapping area can be reliably clamped or gripped regardless of whether the operation is performed by an operating arm or manually, thereby avoiding mutual interference between the first section 201 and the second section 203 and improving operational convenience.

[0042] In an optional implementation, the deflection angle is set in a range of 10°-30°.

[0043] like Figure 3 as well as Figure 4 As shown, in an optional embodiment, a tip 205 is provided at the end of the first section 201 for inserting between adjacent winding layers in the steel coil 100, so that the tip 205 can find the gap between adjacent winding layers for insertion and avoid causing resistance damage to the end faces of the strip steel of the adjacent winding layers.

[0044] In an optional embodiment, the auxiliary part 200 is provided in plurality and can be arranged at intervals on one end face or both end faces of the steel coil 100. The auxiliary part 200 is deformed by bending into the first section 201, the bending section 202 and the second section 203. It should be noted that the auxiliary part 200 can be arranged close to the end of the strip in the inner section of the steel coil 100, and the second section 203 on the auxiliary part 200 is pressed against one side of the strip winding to avoid the unconstrained state of the strip end and improve the constraint effect. After multiple accessories are arranged on both sides of the steel coil 100, the repair effect of the collapsed core state of the steel coil 100 is better and the overall reliability is higher.

[0045] like Figure 3 as well as Figure 4 As shown, in an optional embodiment, the length of the second section 203 is smaller than the length of the first section 201, thereby improving material utilization. It should be noted that the first section 201 extends between adjacent winding layers and is clamped by the strip steel of adjacent winding layers, thereby maintaining the relative position stability of the first section 201. The second section 203 is pressed onto the inner ring of the steel coil 100 with a shorter length, thereby meeting operational requirements.

[0046] In actual operation, the following steps are performed:

[0047] 1) Take a steel bar, determine the length of the bending section 202 by three times the thickness of the steel strip in the steel coil 100, and bend the bending section 202 on both sides to obtain the first section 201 and the second section 203, and keep the angle between the bending lines of the first section 201 and the second section 203 and the vertical line of the center line of the steel bar at 10°, and obtain the auxiliary part 200 after cutting the end of the first section 201 to obtain the tip 205, and repeat to obtain two;

[0048] 2) After the inner ring of the uncased steel coil 100 collapses, the loose inner ring strip is reset;

[0049] 3) Holding the non-overlapping portion 204 on the second section 203, move the auxiliary member 200 to one side of the steel coil 100;

[0050] 4) fine-tuning the first section 201 until the tip 205 is located between the third and fourth winding layers formed by the inner circle of the steel coil 100;

[0051] 5) applying pressure to the bending section 202 in the axial direction of the steel coil 100 until the first section 201 is inserted between the third winding layer and the fourth winding layer, and the second section 203 extends into the inner circle of the steel coil 100, and the second section 203 is pressed against the inner circle of the steel coil 100 by the deformation recovery force;

[0052] 6) Repeat the operation to arrange the two auxiliary parts 200 on both sides of the steel coil 100 respectively, complete the treatment of the core collapse problem of the inner ring of the steel coil 100, and start the subsequent coiling operation of the steel coil 100.
