[0002] In the steel rolling workshop of a metallurgical plant, steel coils are the most common form of steel raw materials. The molten steel is solidified and rolled into a sheet of a certain thickness through continuous casting + hot rolling or direct casting and rolling, and then coiled into coils to facilitate subsequent heat treatment, cold rolling or other processing procedures. Therefore, the quality of the steel coil, especially the quality of the steel coil core, directly affects the quality and completion efficiency of the next process.

[0003] When the coil core has problems such as single or multiple loose circles or drooping of the lead, the coil cannot enter the next process directly and usually needs manual processing, such as manually cutting off the loose inner circle, or manually spot welding or other fixing methods after rotating and compacting the loose inner circle in the opposite direction if it is feasible within the scope of manpower. This method is feasible when the inner circle is not loose much or the steel thickness is thin (<2mm). Once the inner circle is loose a lot, or the steel thickness is thick (>2mm) and hard, it is basically impossible to do it manually.

[0004] At present, various steel coil inner ring spot welding devices have appeared in the industry, and a robot system is used to automatically spot weld the inner ring of the steel coil.

[0030] The technical scheme in the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Although the representative embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that various modifications and changes can be made to the present invention without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the embodiments, but should be limited by the attached claims and their equivalents.

[0031] Reference Figure 1-5 The present invention provides a coil core processing device, including a height adjustment device, a coil supporting device and a welding device; a coil saddle is provided at the lifting end of the height adjustment device; the coil supporting device and the welding device are respectively arranged on both sides of the height adjustment device; the welding device includes a first moving device and a welding gun installed on the first moving device; the coil supporting device includes a second moving device and a coil supporting assembly installed on the second moving device; the coil saddle is located in the working range of the coil supporting assembly and the welding gun.

[0032] When in use, ensure that the center height of the coil support assembly of the coil support device is the same as the theoretical center height when the coil core is processed. The steel coil or other coil to be processed is hoisted to the coil saddle of the height adjustment device by the metallurgical workshop crane or other equipment, and the height of the steel coil is adjusted by the height adjustment device so that the center position of the steel coil to be processed is aligned with the center of the coil support assembly. The number of spot welding and the spot welding position are designed according to the width. The second moving device drives the coil support assembly to move toward the steel coil, so that the coil support assembly is inserted into the first spot welding position farthest from the initial position of the coil support assembly in the steel coil core, and the corresponding lead position is identified. The first moving device drives the welding gun to move to the spot welding position, and welds the lead to form the first weld point. The second moving device drives the coil support assembly to move back to the second spot welding position. After identifying the lead, the welding gun is used to weld to form the second weld point. Operate in sequence until all spot welding operations are completed.

[0033] The support roll assembly can select a device that can provide support for the roll core as needed. It preferably includes a roll and a first driving member; the roll includes a roll shaft and a plurality of fan-shaped plates arranged along the circumference of the roll shaft; a pull rod is provided in the sliding sleeve of the roll shaft; one end of the pull rod is connected to the driving end of the first driving member, and the other end extends out of the roll shaft and is installed with a connector; the connector is provided with a plurality of axial inclined wedge strips corresponding to the fan-shaped plates one by one along the circumference of the roll shaft, and one end of the inclined wedge strip is rotatably connected to the connector; the end of the inclined wedge strip away from the connector is rotatably connected to the fan-shaped plate. The first driving member drives the pull rod to move back and forth axially in the roll shaft, and drives the fan-shaped plate at the other end of the inclined wedge strip to approach or move away from the roll shaft through the connector, thereby realizing the expansion or contraction of the roll, providing support for the roll core, and sorting and compacting the loose or collapsed ring layer inside the steel coil. Optionally, the first driving member is a winding hydraulic cylinder, the winding drum is provided with four claw-shaped fan-shaped plates, and the connecting head is a cross joint, each end of which is connected to an inclined wedge bar.

[0034] Furthermore, the coil support assembly further comprises a rotary drive member for driving the coil to rotate around the coil axis. The rotary drive member drives the coil to rotate in the opposite direction of the strip coiling, so as to better sort out and compact the loose or collapsed coil layer inside the steel coil to be processed. The rotary drive member preferably comprises a brake and a rotary hydraulic motor. The coil rotates forward and reversely under the drive of the rotary hydraulic motor and is braked by the brake.

[0035] Optionally, the first moving device uses a six-axis robot, with a welding tool head installed on the sixth axis, and a welding gun is set on the welding tool head to realize automatic spot welding of the inner ring of the steel coil. The device is located on the other side of the steel coil to be processed, and is offset from the coil core of the steel coil to be processed by a certain distance to facilitate the movement of the robot. The welding device can cooperate with the coil support device to complete the processing of the coil core. The second moving device includes a track, a trolley and a second driving member. The track and the second driving member are installed on the ground, located on one side of the steel coil to be processed, and aligned with the coil core of the steel coil to be processed. The length direction of the track is the same as the width direction of the coil. The coil support assembly is installed on the trolley, and the piston rod of the transverse hydraulic cylinder is connected to the trolley, driving the trolley to move along the center line of the coil on the track, approaching or moving away from the coil to be processed. The second driving member can choose a transverse hydraulic cylinder.

[0036] In a detailed implementation, the coil core processing equipment also includes a coil width measuring device; the coil width measuring device includes a first distance meter and a second distance meter; the first distance meter and the second distance meter are both located on an axis parallel to the center line of the coil; the detection direction of the first distance meter is the moving direction of the first moving device; the detection direction of the second distance meter is the moving direction of the second moving device. That is, the first distance meter and the second distance meter are located on both sides of the coil saddle, opposite to the two end faces of the coil, and on an axis parallel to the center line of the coil to be processed. During the test, the distance between the two distance meters is known, and the distance between the two distance meters and the corresponding end faces is measured respectively to obtain the coil width data. At the same time, it is also possible to determine whether the steel coil is centered on the coil saddle based on the measurement data to prevent the risk of overload and rollover that may exist during the lifting and lowering of the steel coil.

[0037] Furthermore, the coil core processing equipment also includes a coil height measuring device, which measures the coil height to determine the distance that the height adjustment device needs to adjust, so as to ensure that the center position of the steel coil to be processed is aligned with the center of the coil support assembly. The coil height measuring device selects a device with a height measurement function according to needs, and optionally includes a third distance meter, a column and a cantilever; the third distance meter is installed at one end of the cantilever, and the other end of the cantilever is rotatably connected to the column. The column is located on the center line of the steel coil to be processed, and the cantilever is supported and fixed by the column. When the height of the steel coil needs to be measured, the cantilever is rotated to the top of the steel coil to be processed, and the distance to the top of the steel coil to be processed is measured by the third distance meter. The height of the third distance meter is fixed, and the height of the coil saddle is known, so the outer diameter of the steel coil to be processed and the center height of the steel coil can be calculated. After the measurement is completed, the cantilever rotates the third distance meter to the initial vertical position, away from the steel coil to be processed, to make room for the lifting of the steel coil and protect the equipment.

[0038] The first rangefinder, the second rangefinder and the third rangefinder can all be laser rangefinders.

[0039] In order to improve the quality of spot welding, the coil core processing equipment also includes a tape head recognition device for identifying the position of the tape head of the coil core. The tape head recognition device is preferably a high-definition camera, which can be installed on the column of the height measuring device, and its horizontal position is facing the coil core of the coil to be processed. It can take a full picture of the coil core to be processed, and identify the position of the tape head in the coil core to be processed through the image recognition device, providing a basis for automatic spot welding.

[0040] In an optimized implementation, the height adjustment device includes a guide rod, a fixed base and a lifting hydraulic cylinder; the lifting hydraulic cylinder is installed on the fixed base, and the piston rod is connected to the coil saddle; a guide rod hole is provided on the fixed base; one end of the guide rod is connected to the coil saddle, and the other end is inserted into the guide rod hole. The number of guide rods is designed according to needs, and four guide rods are preferably provided to ensure the smooth lifting and lowering of the coil saddle. The device can be located in a pit as a whole, and the fixed base is installed on the foundation in the pit. The coil saddle is connected to the fixed base through a lifting hydraulic cylinder and four guide rods. The lifting hydraulic cylinder is located in the middle of the fixed base and can drive the coil saddle to move up and down; the four guide rods are respectively located at the four corners of the fixed base, and play a guiding role when the coil saddle moves up and down. When the coil saddle drops to the lowest position, its surface is basically flush with the ground.

[0041] The present invention also provides a coil core processing method, comprising the following steps:

[0042] S1. Place the coil to be processed on the coil saddle of the height adjustment device, which is at the lowest position H0. Measure the coil width by the coil width measuring device.

[0043] Specifically, a first distance meter and a second distance meter are respectively arranged on both sides of the coil, opposite to the two end surfaces of the coil, and the two distance meters are both located on an axis parallel to the center line of the coil.

[0044] During the test, the distance S0 between the two distance meters is known. By measuring the distances W1 and W2 between the two distance meters and the corresponding end faces, the coil width W = W0-(W1+W2) can be calculated. Multiple welding points are divided along the width direction in the coil core to ensure that the welding quality meets the final requirements.

[0045] At the same time, the measurement data can also be used to determine whether the steel coil is centered on the coil saddle. If the centering offset exceeds the threshold, there may be a risk of overloading and rollover during the lifting of the coil saddle to lift the coil to be processed. In this case, an alarm will be issued and the workshop crane will intervene to adjust it to a reasonable range.

[0046] S2. The center height of the reel of the coil support device is the theoretical center height of the coil core to be processed. The coil height measuring device is used to measure the outer diameter of the coil, and the distance that the height adjustment device needs to be adjusted is determined. The coil center height is the same as the center center height of the reel of the coil support device before the coil core can be processed.

[0047] Specifically, the coil height measuring device includes a third distance meter, a column and a cantilever; the third distance meter is installed at one end of the cantilever, and the other end of the cantilever is rotatably connected to the column. The column is located on the center line of the steel coil to be processed, and the cantilever is supported and fixed by the column. When the height of the steel coil needs to be measured, the cantilever is rotated to the top of the steel coil to be processed, and the distance to the top of the steel coil to be processed is measured by the third distance meter. The height of the third distance meter is fixed, and the height of the coil saddle is known, so the outer diameter of the steel coil to be processed and the center height of the steel coil can be calculated. After the measurement is completed, the cantilever rotates the third distance meter to the initial vertical position, away from the steel coil to be processed, to make room for lifting the steel coil and protect the equipment.

[0048] S3, the coiling device extends the coil into the coil core of the coil and moves it to the first welding point, which is the farthest away. At this time, the coil has entered the coil core of the coil to be processed. The coil expands and expands the inner coil. At the same time or after the coiling, the coil rotates in the opposite direction of the strip coiling to sort out and compact the loose or collapsed coils inside the coil. When the loose or collapsed coils are sorted out, the coil stops moving. The strip head recognition device is used to identify the position of the strip head in the first welding point, and the welding gun is moved to the strip head position for spot welding.

[0049] S4, the reel shrinks in diameter, and the second moving device drives the reel back to the second welding point, then expands in diameter again, rotates to arrange and compact the inner circle, identifies the position of the lead in the second welding point, and moves the welding gun to the lead position for spot welding.

[0050] S5, repeat S4 until all spot welding operations are completed. The coil support device and welding device return to the initial position, and the coil core processing is completed.

[0061] Embodiment 2:

[0062] This embodiment provides a coil core processing method based on the coil core processing device provided in Embodiment 1, comprising the following steps:

[0063] S1, the steel coil to be processed is hoisted by the crane in the metallurgical workshop to the coil saddle of the height adjustment device, at which time the coil saddle is at the lowest position H0. The center height of the reel of the coil support device is H C It is the theoretical center height of the steel coil core to be processed.

[0064] In the initial state, the distance S0 between the first distance meter and the second distance meter and the distance between the two distance meters and the center of the coil saddle are known. Measure the distances W1 and W2 between the first distance meter and the second distance meter and the corresponding end faces respectively, where the measured W2 is the straight-line distance between the end of the drum and the end face of the steel coil in the initial state. Calculate the width of the steel coil W = W0-(W1+W2). The distance between the center of the steel coil and the first distance meter is W / 2+W1, which is subtracted from the distance between the first distance meter and the center of the coil saddle to obtain the centering offset. Depending on whether the offset exceeds the threshold, it is determined whether the steel coil is centered on the coil saddle.

[0066] S2. The cantilever of the height measuring device rotates to the top of the steel coil to be processed, and the distance H1 to the top of the steel coil to be processed is measured by the third distance meter. The height of the third distance meter is H a , calculate the outer diameter of the steel coil to be processed A = H a -(H0+H1). After the measurement is completed, the cantilever rotates the third distance meter to the initial vertical position, away from the steel coil to be processed, to make room for the steel coil to be hoisted and protect the equipment.

[0067] Calculate the distance the coil needs to rise H = H C-(H0+A / 2), the lifting hydraulic cylinder of the automatic height adjustment device starts, driving the coil saddle to lift the steel coil to be processed by a stroke of H, so that the center of the steel coil to be processed is at the theoretical center height H C .

[0068] S3. The trolley of the coil support device moves L1=(W2+4W / 5) on the track toward the steel coil. At this time, the reel has entered the coil core of the steel coil to be processed and left some space for welding. The reel starts to support the coil under the drive of the support hydraulic cylinder, and rotates in the opposite direction of the strip coiling under the drive of the rotary hydraulic motor to achieve the purpose of sorting and compacting the loose or collapsed coils inside the steel coil to be processed. The support and rotation can be operated simultaneously or separately according to the actual situation of the looseness or collapse of the steel coil.

[0070] S4, the roll is reduced in diameter, and the trolley moves L2=W / 5 in the direction away from the steel coil, so that the roll part exits the coil core and then expands in diameter again, arranging and compacting the internal ring layer.
