Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
FIG. 1 is a schematic view of an on-line steel cutting system according to an embodiment of the present disclosure. Referring to fig. 1, an embodiment of the present disclosure provides an on-line steel cutting system, which includes a double-sided shearing machine 100, a cutting machine 200, and a centering device 300. The cutting machine 200 is disposed above the roller table 110 of the double-sided shearing machine 100. The centering device 300 is located at the front end of the cutter 200 in the conveying direction of the intermediate plate 400. When the double-sided shearing machine is used, the edges of two sides of a steel plate in the width direction are cut off by the double-sided shearing machine 100 to obtain a middle plate 400 with the same width; then, the centering device 300 is used for adjusting the position of the middle plate 400, so that the width direction of the middle plate 400 is consistent with the cutting direction of the cutting machine 200 positioned at the rear end of the centering device 300; after the position adjustment of the middle plate 400 is completed, the middle plate continues to move on the roller table 110 toward the cutting machine 200 until the middle plate moves to the cutting position below the cutting, and the cutting machine 200 cuts off the middle plate 400 in the width direction.

However, if the intermediate plate 400 is directly conveyed to the cutting position below the cutter 200 and cut by the cutter 200, the width of the intermediate plate 400 may be shifted during the conveyance process, so that the size of the final steel plate cut by the cutter 200 may vary, and the yield of the final plate may be reduced.
Therefore, in the present application, in order to ensure the length and width dimensions of the final plate material, the centering device 300 is used to adjust the position of the intermediate plate material 400 before the operation of cutting the intermediate plate material 400 in the width direction, so as to ensure that the width direction is consistent with the cutting direction of the cutting machine 200.
Referring to fig. 1, in one embodiment, the centering device 300 is installed at both sides of the roller table 110, and adjusts the position of the middle plate 400 by pushing the edge of the middle plate 400. For example: the number of the centering devices 300 is 4, the centering devices are installed on two sides of the roller table 110 and can move independently respectively, the centering devices are arranged in an array, and the distance between every two adjacent centering devices 300 is 3-7m along the conveying direction of the middle plate 400. Each centering device 300 includes a driving mechanism 310, an adjusting mechanism 320, and a rail 330, wherein the adjusting mechanism 320 is slidably disposed on the rail 330, the driving mechanism 310 drives the adjusting mechanism 320, and the adjusting mechanism 320 can slide on the rail 330 in a reciprocating manner. The drive mechanism 310 may be a hydraulic or pneumatic cylinder.
In other embodiments, 2 centering devices 300 may be provided, and two centering devices 300 are respectively installed on two sides of the roller table 110.
The middle plate 400 after the excessive waste on the two side edges of the steel plate is cut off by the cutter 120 continues to move forward on the roller table 110. Photoelectric sensors (not shown in the figure) are installed on two sides of the roller table 110 to monitor the moving state of the middle plate 400, when the middle plate 400 moves to the position where the photoelectric sensors are located, that is, the middle plate 400 reaches the position adjustment position, at the moment, the photoelectric sensors transmit signals at the moment to a controller electrically connected with the photoelectric sensors, the controller immediately and respectively controls 4 driving mechanisms 310 to operate, the driving mechanisms 310 respectively drive adjusting mechanisms 320 connected with the driving mechanisms and located on two sides of the roller table 110, so that the adjusting mechanisms 320 slide towards the middle plate 400 on the rails 330, the adjusting mechanisms 320 are contacted and act on the middle plate 400, the middle plate 400 moves under the pushing of the adjusting mechanisms 320 until the width direction of the middle plate 400 is consistent with the cutting direction of the cutting machine 200 under the pushing of the adjusting mechanisms 320, and the position adjustment of the middle plate 400 is completed. The controller then controls the 4 driving mechanisms 310 to operate in reverse, so that the 4 adjusting mechanisms 320 all move away from the middle plate 400, and reset, so as to adjust the position of the middle plate 400 next time.
When the middle plate 400 is shifted to the same side of the roller table 110, the centering devices 300 arranged in an array can be operated independently to adjust the position of the middle plate 400. And the plurality of centering devices 300 can improve the accuracy of position adjustment in the position adjustment of the middle plate 400.
In other embodiments, the centering device 300 may also be installed below the roller table 110, and abut against the lower surface of the middle plate 400 in a lifting manner to lift the middle plate, and then horizontally move to adjust the position of the middle plate 400. For example: there are also 4 centering devices 300, which can move independently and are arranged in an array, and the distance between two adjacent centering devices 300 is 3-7m along the conveying direction of the middle plate 400. Each centering device 300 comprises a driving mechanism 310, an adjusting mechanism 320, a rail 330 and a first lifting mechanism, wherein the driving mechanism 310, the adjusting mechanism 320, the rail 330 and the first lifting mechanism are all arranged below the roller table 110 of the double-sided shearing machine. The adjusting mechanism 320 is slidably disposed on the rail 330, the driving mechanism 310 drives the adjusting mechanism 320 so that the adjusting mechanism 320 can slide on the rail 330 in a reciprocating manner, and the first lifting mechanism is connected to the adjusting mechanism 320 in a driving manner.
At this time, the adjusting mechanism 320 includes a block-shaped pushing head and a friction increasing member disposed on the upper end surface of the pushing head, and the friction increasing member may be a rubber member covering the upper end surface of the pushing head. The first lifting mechanism is in driving connection with the lower end face of the push head and is located below the push head, the push head is driven by the first lifting mechanism to ascend or descend, the adjusting mechanism 320 is located above the roller table 110 or below the roller table 110, and when the adjusting mechanism 320 is located above the roller table 110, the friction increasing piece in the adjusting mechanism 320 abuts against the middle plate 400. The lower end of the pushing head is also connected with the rail 330 in a sliding manner, the driving mechanism 310 is located at one side of the pushing head and is connected with the pushing head in a driving manner, and the pushing head can slide on the rail 330 in a reciprocating manner under the driving of the driving mechanism 310.
At this time, the photoelectric sensors are still installed on both sides of the roller table 110 to monitor the moving state of the middle plate 400. When the middle plate 400 reaches the position of the photoelectric sensor and the middle plate 400 reaches the position-adjusting orientation, the controller electrically connected with the photoelectric sensor first controls the driving mechanism 310 to drive the pushing head to slide on the rail 330 toward the middle plate 400, until the pushing head moves to the lower side of the middle plate 400, the controller controls the driving mechanism 310 to pause. Next, the controller immediately controls the first lifting mechanism to operate, drives the push head located below the roller way 110 to ascend until the push head is located above the roller way 110, and in the process, the friction increasing piece at the upper end of the push head abuts against the middle plate 400, so that the middle plate 400 is jacked to a certain distance above the roller way 110, and then the first lifting mechanism stops operating. The driving mechanism 310 operates again to drive the pushing head to slide along the rail 330, so as to drive the middle plate 400 located above the adjusting mechanism 320 to move synchronously until the width direction of the middle plate 400 is consistent with the cutting direction of the cutting machine 200, and the operation of the driving mechanism 310 is suspended again. Then, the first lifting mechanism drives the push head to descend again until the push head and the friction increasing member descend below the roller table 110, and the intermediate plate 400 returns to the roller table 110 again, so that the position adjustment of the intermediate plate 400 is completed. Thereafter, the centering device 300 is reset so that the position of the intermediate plate 400 is adjusted next time.
At this time, when the friction increasing member abuts against the middle plate 400 and moves along the rail 330, the friction force between the middle plate 400 and the friction increasing member is increased, the two members are not easy to slide relatively, the moving consistency of the two members is ensured, and the accuracy of adjusting the position of the middle plate 400 is increased.
Referring to fig. 1, after the position adjustment of the middle plate 400 is completed, the middle plate 400 continues to move forward on the roller table 110 until the middle plate moves to the cutting position below the cutting head 210, and the cutting machine 200 completes the cutting of the middle plate 400 along the width direction thereof. The identification of the cutting position can still be accomplished using a photosensor and a controller.
Fig. 2 is a schematic view of a structure of a cutting machine in an embodiment of the present application. Referring to fig. 1 and 2, in the present embodiment, the cutting machine 200 includes a base 220 and a cutting head 210, wherein the cutting head 210 is a flame-type cutting head, and the cutting direction faces the middle plate 400. The base 220 is located the top of roll table 110 and sets up with roll table 110 interval, and the crop 210 slides and sets up in base 220, and the setting of sliding between crop 210 and the base 220 can rely on the rail to realize.
When the middle plate 400 moves to the cutting position, the cutting head 210 is started and slides along the base 220, the cutting direction of the cutting head 210 is consistent with the sliding direction of the cutting head, and the sliding direction of the cutting head 210 is consistent with the width direction of the middle plate 400, so that the middle plate 400 can be cut off in the width direction.
In other embodiments, the cutting machine 200 may be installed below the roller table 110 of the double-sided shearing machine 100, and the roller table 110 corresponding to the upper side of the cutting machine 200 may be configured to be opened and closed in a sliding manner. When the middle plate 400 reaches the cutting position, the roller ways 110 above the cutting machine 200 slide relatively to expose the cutting machine 200 below the cutting machine 200, and the cutting direction of the cutting head 210 faces upward. The cutting head 210 is activated and the cutting head 210 slides along the rail on the base 220, thereby cutting the middle plate 400 in the width direction. After the cutting is completed, the roller ways 110 above the cutting machine 200 slide in opposite directions to shield the cutting machine 200, and the cutting machine is restored to the initial state.
The cutter 200 cuts the intermediate plate member 400 in the width direction, and divides the intermediate plate member 400 into final plate members having a predetermined length and a predetermined width. The final plate can be directly conveyed to a warehouse for warehousing by the roller table 110.

Meanwhile, the centering device 300 can adjust the position of the middle plate 400 first, so that the width direction of the middle plate 400 is consistent with the cutting direction of the cutting machine 200, the cutting precision of the middle plate 400 in the width direction is improved, and the quality of the finished product of the final plate is further improved.
Referring to fig. 2, in order to adjust the cutting strength, the cutting machine 200 further includes a second lifting mechanism 230, and the second lifting mechanism 230 is disposed on the base 220. When the thickness of the middle plate 400 is changed to require the cutting strength of the cutting head 210 to be changed, the cutting power can be generally changed. In addition, the second elevating mechanism 230 may be raised or lowered to raise or lower the base 220 so as to synchronously raise or lower the cutting head 210 slidably installed on the base 220, thereby changing the distance between the cutting head 210 and the middle plate member 400 and changing the cutting strength of the cutting head 210.
In order to increase the precision of cutting the middle plate 400, a plate 240 is fixed to the bottom of the base 220 at intervals, the base 220 is disposed parallel to the plate 240, and heat insulation wool 250 is filled between the base 220 and the plate 240. The heat insulation wool 250 between the base 220 and the plate 240 serves as a heat insulation shock absorption layer, so that the deformation of the base 220 caused by long-time baking of the cutting head 210 can be reduced, and the vibration generated when the cutting head 210 slides on the base 220 can be reduced. Meanwhile, when the base 220 descends, the heat insulation cotton 250 is compressed, when the base 220 ascends, the heat insulation cotton 250 expands, and the heat insulation shock absorption layer can play a role in buffering when the base 220 descends and ascends.
