Description

Technical Field

[0001] This utility model relates to the field of bar and wire rod production technology, specifically to a device for preventing steel from piling up at the cut end of rolled steel. Background Technology

[0002] In steel bar and wire rod production lines, flying shears are installed at the entrance of key rolling mills to cut off steel bars with low head temperatures and those that are substandard. After cutting, these headed steel bars fall into the rolling mill channel, causing steel pile-up and other malfunctions that affect normal production. Currently, the flying shear cutting off the head relies solely on manual observation. When a head is found, the rolling mill is stopped and manually handled to reduce malfunctions. However, manual observation has significant uncertainties: firstly, the timing of detection is unpredictable, and secondly, labor costs are high, requiring constant monitoring of the operating status; otherwise, situations where headed steel bars are not easily detected may occur. Therefore, it is impossible to prevent malfunctions in real time. Utility Model Content

[0003] This invention provides a device to prevent steel from piling up at the cut end of a rolled steel plant, thereby solving the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A device for preventing steel from piling up at the cut end of a rolling mill, comprising:

[0006] Flying shears are used to cut the head of rolled steel, thus forming a cut head;

[0007] A collection area is located at the lower part of the flying shear;

[0008] The shear head drop channel is installed in the collection area and located at the lower part of the flying shear;

[0009] An adjustable bracket is installed in the collection area;

[0010] A hot metal detector, mounted on the adjustment bracket and located at the lower part of the cutter head drop channel, is used to detect the dropped cutter head;

[0011] A scrap steel hopper, located below the cut-off section, is used to collect the cut-off pieces.

[0012] In one possible design, the collection area includes:

[0013] First sidewall;

[0014] Second sidewall;

[0015] The bottom and both sides are respectively connected to the first sidewall and the second sidewall;

[0016] The first sidewall, the second sidewall, and the bottom form a receiving space.

[0017] In one possible design, the decapitation drop channel includes:

[0018] First side panel;

[0019] The second side panel is arranged parallel to the first side panel.

[0020] In one possible design, the decapitation drop channel also includes:

[0021] The first mounting plate is connected to the first side plate on one side and to the first side wall on the other side.

[0022] The second mounting plate is connected to the second side plate on one side and to the second side wall on the other side.

[0023] In one possible design, the adjustment bracket includes:

[0024] crossbar;

[0025] The first upright is rotatably connected to the horizontal bar;

[0026] The second upright is embedded inside the first upright and is slidably connected to the first upright.

[0027] In one possible design, the first upright and the second upright have multiple threaded holes along the axial direction, and the first upright and the second upright are connected by bolts passing through the threaded holes.

[0028] In one possible design, the first upright has an internal thread, the second upright has an external thread, and the first upright and the second upright are screwed together.

[0029] In one possible design, the adjustment bracket includes:

[0030] A sliding plate is installed on the first side wall, with a sliding rail provided;

[0031] The slider is embedded in the slide rail at its top.

[0039] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0040] This utility model provides a device to prevent steel scrap from piling up in the rolling mill. By setting up a scrap steel hopper and a scrap steel drop channel, the length of the scrap steel drop channel along the rolling direction is greater than that of the flying shear, and the diameter of the scrap steel hopper is greater than the outlet of the scrap steel drop channel. This ensures that every scrap cut by the flying shear falls into the scrap steel hopper from the outlet of the scrap steel drop channel, effectively preventing scrap from falling into the rolling mill channel and causing steel piling up, thus avoiding disruption to normal production. Furthermore, by installing a hot metal detector, every scrap cut by the flying shear is detected. If the flying shear performs a cutting operation but the hot metal detector does not detect a fallen scrap, it indicates that the scrap may have entered the rolling mill channel, requiring operator intervention. The hot metal detector further effectively prevents scrap from falling into the rolling mill channel and causing steel piling up, thus avoiding disruption to normal production.

[0044] The present invention will be further described in detail below with reference to embodiments:

[0045] like Figure 1-2As shown, this utility model provides a device for preventing the accumulation of steel cut heads during rolling mill operations, including: a flying shear 1, a collection area 4, a cut head drop channel 5, an adjusting bracket 6, a hot metal detector 7, and a scrap steel hopper 9. The flying shear 1 is used to cut the head of the rolled steel 2, thereby forming a cut head 3. The collection area 4 is located at the lower part of the flying shear 1, and its length is greater than that of the flying shear 1 along the rolling mill's forward direction. With this design, the cut head 3 is pushed forward by the rolling mill, and the flying shear 1 cuts off the cut head 3. On the one hand, the cut head 3 moves downward under the influence of gravity; on the other hand, the cut head 3 moves forward under the pushing force of the rolling mill. Therefore, the collection area 4 is located below the flying shear 1 and extends forward. The head-cutting drop channel 5 is installed in the collection area 4, located below the flying shear 1 and extending forward. That is, the head-cutting drop channel 5 is set below the flying shear 1 and extends to the lower left. The head-cutting drop channel 5 is set at an acute angle to the vertical direction and extends from the upper right to the lower left. The upper right opening of the head-cutting drop channel 5 is located below the flying shear 1. Along the rolling direction, the upper right opening of the head-cutting drop channel 5 is longer than the flying shear 1, thereby ensuring that all the falling head 3 can enter the head-cutting drop channel 5, effectively preventing the head 3 from falling into the rolling line channel and causing steel pile-up and other faults, thus avoiding affecting the normal operation of production. An adjusting bracket 6 is installed in the collection area 4, and a hot metal detector 7 is installed on the adjusting bracket 8 and located below the head dropping channel 5 to detect the falling heads 3. A scrap steel hopper 9 is located below the head dropping channel 5 to collect the heads 3. The diameter of the scrap steel hopper 9 is larger than the outlet of the head dropping channel 5, thereby ensuring that all heads 3 passing through the head dropping channel 5 can fall into the scrap steel hopper.

[0046] The device for preventing steel pile-up of cut ends provided by this utility model is designed with a cut end drop channel 5 and a scrap steel hopper 9. The length of the cut end drop channel 5 along the forward direction of the rolling mill 2 is greater than that of the flying shear 1, and the diameter of the scrap steel hopper 9 is greater than that of the outlet of the cut end drop channel 5. This ensures that each cut end 3 cut by the flying shear 1 falls into the cut end drop channel 5 and then enters the scrap steel hopper 9 from the outlet of the cut end drop channel 5. This effectively prevents the cut ends 3 from falling into the rolling mill channel and forming steel pile-up, thus avoiding disruption to normal production. Furthermore, a hot metal detector 7 is installed. Each cut end 3 cut by the flying shear 1 is detected by the hot metal detector 7. If the flying shear 1 performs a cutting operation but the hot metal detector 7 does not detect the fallen cut end 3, it indicates that the cut end 3 may have entered the rolling mill channel. The operator then handles the situation. By installing the hot metal detector 7, the device further effectively prevents the cut ends 3 from falling into the rolling mill channel and forming steel pile-up, thus avoiding disruption to normal production.

[0047] In one possible design, the collection area 4 includes a first sidewall 41, a second sidewall 42, and a bottom 43. The bottom 43 is connected to the first sidewall 41 and the second sidewall 42 on both sides, respectively. The first sidewall 41, the second sidewall 42, and the bottom 43 form a receiving space. The collection area 4 facilitates the installation and placement of the head drop channel 5, the hot metal detector 7, and the scrap steel hopper 9.

[0048] In one possible design, the head-dropping channel 5 includes: a first side plate 51 and a second side plate 52 arranged in parallel. The first side plate 51 and the second side plate 52 are inclined from the upper right to the lower left, forming an acute angle with the vertical direction. The inclination direction of the first side plate 51 and the second side plate 52 is consistent with the falling trajectory of the head 3, ensuring that the falling head 3 enters the head-dropping channel 5.

[0049] In one possible design, the head-dropping channel further includes: a first mounting plate 53 and a second mounting plate 54. One side of the first mounting plate 53 is connected to the first side plate 51, and the other side is connected to the first side wall 41; one side of the second mounting plate 54 is connected to the second side plate 52, and the other side is connected to the second side wall 42. By setting the first mounting plate 53, the first side plate 51 is fixedly mounted on the first side wall 41; by setting the second mounting plate 54, the second side plate 52 is fixedly mounted on the second side wall 42.

[0050] In one possible design, the adjusting bracket 6 includes a crossbar 61, a first upright 62, and a second upright 63. The first upright 62 is rotatably connected to the crossbar 61. The second upright 63 is embedded within the first upright 62 and slidably connected to it. The end of the second upright 63 is connected to a hot metal detector 7. By setting the first upright 62 and the second upright 63 to be slidably connected, the vertical height of the hot metal detector 7 can be easily adjusted. By setting the crossbar 61 and the first upright 62 to be rotatably connected, the horizontal direction of the hot metal detector 7 can be easily adjusted. This allows the position of the hot metal detector 7 to be adjusted according to the trajectory of the cutting head 3 and the cutting head falling channel 5.

[0051] In one possible design, the first upright 62 and the second upright 63 have multiple threaded holes along the axial direction, and the first upright 62 and the second upright 63 are connected by bolts passing through the threaded holes. The bolted connection is stable and reliable. By connecting and securing the first upright 62 and the second upright 63 through the different threaded holes, the second upright 63 can be raised or lowered relative to the first upright 62, thereby achieving the adjustment of the vertical height of the hot metal detector 7.

[0052] In one possible design, the first upright 62 has an internal thread, and the second upright 63 has an external thread on its outer periphery. The first upright 62 and the second upright 63 are screwed together. By setting the screwed-in internal and external threads, precise adjustment of the lifting and lowering of the second upright 63 relative to the first upright 62 can be achieved, facilitating precise adjustment of the vertical height of the hot metal detector 7.

[0053] In one possible design, the adjusting bracket 6 includes: a sliding plate 64, a slider 65, a first motor, a lead screw, and a vertical plate 66. The sliding plate 64 is horizontally positioned and mounted on the first side wall 41, with a horizontally positioned slide rail along its length. The top of the slider 65 is embedded in the slide rail. The first motor is mounted on one side of the slider 65. The end of the lead screw shaft is connected to the first motor, and the nut end of the lead screw is connected to the top of the vertical plate 66. The bottom of the vertical plate 66 is connected to the hot metal detector 7. By driving the lead screw with the first motor, precise lifting and automatic adjustment of the vertical plate 66 and the hot metal detector 7 can be achieved. By setting the horizontal sliding plate 64 and the slider 65, horizontal adjustment of the hot metal detector 7 can be achieved.

[0054] In one possible design, the adjusting bracket 6 further includes a second motor, mounted on the other side of the slider 65, for driving the slider 65 to move along the slide rail. By setting the second motor, the automatic horizontal adjustment of the slider 65 and the hot metal detector 7 is realized. The starting and stopping of the second motor realizes the horizontal movement and limiting and fixing functions of the slider 65 and the hot metal detector 7.

[0055] In one possible design, it also includes a controller electrically connected to the flying shear 1 and the hot metal detector 7.

[0056] In one possible design, this utility model provides a method for detecting and alarming the shear head of a bar / wire cutting process. A rolling mill is arranged before and after the shear head 1. When the rolled steel 2 passes through the shear head 1, the shear head 1 calculates the action time based on a set length. A shear head drop channel 5 is set below the shear head 1. After the shear head 1 completes its cutting action, the cut head 3 falls along the channel. A scanning hot metal detector 7 is installed below the channel. The hot metal detector 7 can detect the entire area of ​​the channel. When the cut head 3 falls, the hot metal detector 7 can detect it. Upon detection, the signal is transmitted to the controller. The controller performs logical operations to determine whether the cut head drop is normal if the detector detects a signal after the shear action, and abnormal if no signal is detected. The controller sends an alarm signal to the main control panel. After receiving the alarm signal, the operator sends the alarm information to the on-site maintenance personnel. The on-site maintenance personnel check whether the cut head is abnormal. If the cut head falls into the steel passage channel, it is removed promptly to prevent subsequent rolling failures caused by the cut head, thereby reducing the number of failures caused by the cut head.

[0057] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
