Description

Technical Field

[0001] The present invention belongs to the technical field of steel sorting, and particularly relates to a non-standard-length steel sorting device and a sorting system. Background Art

[0002] In the production and sales of steel, "standard-length" and "non-standard-length" are two common steel length specifications, and their main differences lie in the degree of length standardization and application scenarios.

[0003] Standard-length steel refers to steel produced according to a fixed length specified by the user. This length is pre-determined and is usually used in projects or processing scenarios that require precise dimensions. Due to the need for customized production, its production cost and selling price are usually higher than those of non-standard-length steel. Non-standard-length steel refers to steel produced within a standard length range during the production process, and its length usually has a certain fluctuation range (such as 6 - 12 meters, 9 - 15 meters, etc.). The length of this kind of steel is not fixed but is determined according to the actual conditions during the production process.

[0004] On a hot-rolled steel production line, the steel is conveyed from the cooling bed to a fixed-length shearing machine for shearing to obtain standard-length steel that meets the specifications. During this process, some short-length steel may be produced during the first shear and the last shear. To ensure the quality of the finished product, these short-length steel must be separated from the standard-length steel before entering the bundling machine.

[0005] Currently, the separation of short-length steel mainly relies on manual labor on the CD roller table. Workers need to quickly identify and pick out the short-length steel on the conveyor roller table through tools such as iron hooks. However, when the quantity of steel is large, workers cannot timely hook out the short-length steel from the CD roller table, and still some short-length steel will enter the bundling machine. Summary of the Invention

[0006] The purpose of the present invention is to provide a non-standard-length steel sorting device and a sorting system to timely screen the short-length steel on the CD roller table and improve production efficiency.

[0007] The present invention adopts the following technical solutions: A non-standard-length steel sorting device includes columns respectively arranged on both sides of the CD roller table;

[0008] A horizontal fixed rod is arranged between the two columns. The fixed rod extends from one side of the CD roller table to the other side, and the fixed rod is higher than the roller body of the CD roller table;

[0009] It further includes a moving rod, which is arranged parallel to the fixed rod and is located directly below the fixed rod;

[0010] A strip-shaped gap for the moving rod to pass through is opened on the guard plate of the CD roller table between the fixed rod and the moving rod;

[0011] The movable rod is installed on the first driving device, and the first driving device is used to drive the movable rod to move up and down.

[0012] Furthermore, a strip-shaped space in the vertical direction is provided in the middle of the column;

[0013] Both ends of the fixed rod are respectively fixed in the two strip-shaped spaces;

[0014] Both ends of the movable rod are respectively located in the two strip-shaped spaces.

[0015] Furthermore, a support rod is provided at the bottom of the strip-shaped space, and the support rod at the bottom is located below the movable rod.

[0016] Furthermore, a support rod is also provided at the top of the strip-shaped space. The support rod at the top is located above the fixed rod and is fixedly connected to the fixed rod.

[0017] Furthermore, both the fixed rod and the movable rod are round rods or round tubes.

[0018] Furthermore, the tops of the two columns are connected by a cross beam;

[0019] A bottom plate (170) is provided at the bottom end of each column;

[0020] The first driving device is installed on the cross beam or the bottom plate (170).

[0021] Furthermore, the distance between the fixed rod and the outlet of the CD roller path is less than or equal to the length of the specified-length steel and greater than the length of the short-length steel.

[0022] Another technical solution of the present invention: A non-specified-length steel sorting system includes a non-specified-length steel sorting device according to any one of the above;

[0023] It further includes a baffle provided at the outlet of the CD roller path. The baffle extends from one side of the CD roller path to the other side, and the baffle can move up and down relative to the CD roller path.

[0024] Furthermore, a second driving device is provided at the top of the baffle.

[0025] Furthermore, a cold shear is provided at the inlet of the CD roller path.

[0026] The beneficial effect of the present invention is that: by providing a fixed rod and a movable rod on the CD roller path, when the short-length steel on the CD roller path passes below the fixed rod and the specified-length steel does not pass below the fixed rod, the movable rod moves from bottom to top towards the fixed rod, and by driving the specified-length steel towards the fixed rod until the fixed rod and the movable rod clamp the specified-length steel, the sorting of the specified-length steel and the short-length steel can be realized.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation manners.

[0037] The present invention discloses a non-standard-length steel sorting device, as shown in Figure 1 and Figure 2 , which includes columns 150 respectively arranged on both sides of the CD roller table 400; a horizontal fixed rod 130 is arranged between the two columns 150, and the fixed rod 130 extends from one side of the CD roller table 400 to the other side, and the fixed rod 130 is higher than the roller body of the CD roller table 400; it further includes a moving rod 140, the moving rod 140 is arranged parallel to the fixed rod 130 and is located directly below the fixed rod 130 (that is, the projection planes of the two in the horizontal direction have an intersecting part); a strip-shaped gap for the moving rod 140 to pass through is opened on the guard plate of the CD roller table 400 between the fixed rod 130 and the moving rod 140; the moving rod 140 is installed on a first driving device, and the first driving device is used to drive the moving rod 140 to move up and down. The roller body is the main part of the roller in the CD roller table 400 that participates in transporting materials.

[0038] In the present invention, by providing a fixed rod 130 and a moving rod 140 on the CD roller path 400, when the short-length steel on the CD roller path 400 passes under the fixed rod 130 and the fixed-length steel does not pass under the fixed rod, the moving rod 140 moves upward towards the fixed rod 130, driving the fixed-length steel 500 to move towards the fixed rod 130 until the fixed rod 130 and the moving rod 140 clamp the fixed-length steel 500, enabling the sorting of the fixed-length steel 500 and the short-length steel 600.

[0039] A strip-shaped space in the up-and-down direction is provided in the middle of the column 150; both ends of the fixed rod 130 are respectively fixed in the two strip-shaped spaces; both ends of the moving rod 140 are respectively located in the two strip-shaped spaces. By providing the strip-shaped space on the column 150, the moving path of the moving rod 140 can be limited to prevent it from running off course, so that the fixed-length steel 50 can be stably clamped. Moreover, the fixed rod 130 and the moving rod 140 are in the strip-shaped space, which can also prevent the two from accidentally falling and affecting the normal operation of other equipment.

[0040] Regarding the strip-shaped space, it can also be composed of two sub-columns arranged in parallel to form the column 150 together, which can eliminate the need for processing the strip-shaped space and reduce the processing difficulty.

[0041] A support rod 160 is provided at the bottom of the strip-shaped space, and the support rod 160 at the bottom is located below the moving rod 140. By designing the support rod 160, the moving rod 140 can be supported, which is convenient for operation when disassembling or replacing the moving rod 140.

[0042] A support rod 160 is provided at the top of the strip-shaped space, and the support rod 160 at the top is located above the fixed rod 130 and is fixedly connected to the fixed rod 130. Since the moving rod 140 moves upward to apply force, higher requirements are put forward for the firmness of the fixed rod 130. Therefore, adding a support rod 160 in the force direction of the fixed rod 130 can make the fixed rod 130 more stable.

[0043] The form of the support rod 160 can be various, it can be plate-shaped, rod-shaped, groove-shaped, etc., and it can also be a non-standard shape, all based on stability.

[0044] In the present invention, both the fixed rod 130 and the moving rod 140 are round rods or round tubes. In this way, the contact parts of the two are tangent, in a linear clamping form, and the clamping line is similar to chopsticks picking up vegetables, with a greater clamping force, which can effectively prevent the fixed-length steel 500 from being continuously taken away by the CD roller path 400 due to too small or uneven clamping force.

[0045] In addition, a soft cushion layer is also provided on the clamping areas of the fixed rod 130 and the moving rod 140 to prevent the clamping areas of the fixed rod 130 and the moving rod 140 from damaging the threads on the surface of steel materials such as threaded steel during clamping.

[0046] The tops of the two columns 150 are connected by a cross beam 110; a bottom plate 170 is provided at the bottom end of each column 150; the first driving device is installed on the cross beam 110 or the bottom plate 170. The structural stability of the sorting device can be increased through the cross beam 110 and the bottom plate 170. When the first driving device is installed on the cross beam 110, its output shaft faces downward, and when the first driving device is installed on the bottom plate 170, its output shaft faces upward. Comparatively speaking, installing the first driving device on the bottom plate 170 is safer, but due to the presence of the CD roller path 400, there may be no installation conditions on the bottom plate 170, and in this case, it can be installed on the cross beam 110.

[0047] It should be noted that the distance between the fixed rod 130 and the outlet of the CD roller path 400 is less than or equal to the length of the specified-length steel 500 and greater than the length of the short-length steel 600. Since the steel materials move passively on the CD roller path 400 and at the same moving speed, the fronts of both the specified-length steel 500 and the short-length steel 600 are flush. This is because they are formed by cold shearing simultaneously. Therefore, when the specified-length steel 500 and the short-length steel 600 move simultaneously and their fronts are flush, the difference between the two lies in the rear end. The rear end of the specified-length steel 500 is further back than the rear end of the short-length steel 600.

[0048] Therefore, through the limitation of the above length conditions, it can be ensured that each time the fixed rod 130 and the moving rod 140 clamp the specified-length steel 500, thereby realizing their separation.

[0049] The present invention also discloses a non-specified-length steel sorting system, including the above-mentioned non-specified-length steel sorting device; it also includes a baffle 310 provided at the outlet of the CD roller path. The baffle 310 extends from one side of the CD roller path 400 to the other side, and the baffle 310 can move up and down relative to the CD roller path 400.

[0050] When the baffle 310 drops, its lower end is at the same height as the CD roller path 400, and it can block the specified-length steel 500 and the short-length steel 600 moving from the direction of the sorting device. Thus, the fronts of the steel materials in the same batch are blocked by the baffle 310, creating a distance difference at the rear ends of the two types of steel materials, enabling the fixed rod 130 and the moving rod 140 to clamp the rear ends of the specified-length steel 500. Furthermore, when the baffle 310 rises, the short-length steel 600 will continue to move forward below the baffle 310, realizing the sorting of the two types of steel materials.

[0051] In the present invention, since the baffle 310 is located above the CD roller path 400, a second driving device is provided at the top of the baffle 310, avoiding occupying the space of the CD roller path 400. It should be noted that both the first driving device and the second driving device can be selected as needed. For example, in this application, the first driving device is selected as the first cylinder 120 and the second driving device is selected as the second cylinder 300.

[0052] In addition, a cold shear 200 is provided at the entrance of the CD roller path 400. The steel can be cut into fixed-length steel 500 or short-length steel 600 by the cold shear 200.

[0053] Next, Figures 3 - 7 a detailed working process of the present invention will be described and explained.

[0054] As Figure 3 and Figure 4 shown, the column 150 is made of 14# channel steel, the cross beam 110 is made of a steel plate with dimensions of 3850mm×300mm×30mm, and the sorting device has a height of 1740mm and a span of 2550mm. The two cylinders are both of the QGBZ 125-250-MPI model, with a stroke of 250mm and a cylinder diameter of 125mm. The fixed rod 130 is made of a φ90mm steel pipe with a length of 2600mm and is welded and fixed to the column 150 to provide a solid fixed support for the device. The moving rod 140 is made of a φ90mm steel pipe with a length of 3400mm and can move flexibly under the drive of the cylinder.

[0055] The uncut steel is transported from the cold bed to the cold shear 200, and the cold shear 200 cuts the steel according to the preset size. Since the lengths and arrival times of the steel entering the cold shear 200 are different, some of the steel is at the head or tail end during cutting, resulting in short-length steel 600 after cutting.

[0056] After the cold shear 200 finishes cutting, as Figure 3 and Figure 4 shown, the fixed-length steel 500 and the short-length steel 600 move forward under the drive of the CD roller path 400. When the front ends of these steels approach the exit of the CD roller path 400, the baffle 310 drops under the drive of the second cylinder 300 to block the front ends of these steels, making their fronts face each other. This is because the lengths of the fixed-length steel 500 and the short-length steel 600 are different, and the positions of the tails of the two types of steel are also different. The tail end of the fixed-length steel 500 is behind the sorting device, and the tail end of the short-length steel is in front of the sorting device.

[0057] Next, start the first cylinder 120 to drive the moving rod 140 to move upward, and at the same time drive the tail end of the fixed-length steel 500 to rise until the moving rod 140 and the fixed rod 130 clamp the tail end of the fixed-length steel 500, as Figure 5 and Figure 6 shown. At this time, the tail end of the short-length steel 600 is not clamped.

[0058] Then, as Figure 7 shown, raise the baffle 310 through the second cylinder 300. The short-length steel 600 continues to move forward under the drive of the CD roller path 400. Since the tail end of the fixed-length steel 500 is clamped, its position remains unchanged until the short-length steel 600 enters the collection area, and then drive the first cylinder 120 to drive the moving rod 140 to move downward, and the fixed-length steel 500 continues to be driven forward by the CD roller path 400.

[0059] In this way, it can be ensured that the fixed-length steel 500 and the short-length steel 600 enter the steel collection area in batches, realizing the separation of the fixed-length steel 500 and the short-length steel 600.

[0060] Based on the existing production line equipment, the present invention adds an independent mechanical component, which is designed specifically for the steel separation task and does not rely on a complex electronic control system, simplifying the overall structure. By using the precise control of the cylinder, the automatic lifting, clamping, and separation of the steel are realized, which is crucial for improving the separation efficiency and accuracy. The device design focuses on simplicity, is easy to integrate into the existing production line, and is convenient for installation and operation. Due to the simple structure, the manufacturing and maintenance costs are relatively low, making the device have a high cost-benefit ratio. The device can adapt to bar production lines of different specifications, with good versatility and flexibility. The simplified design also means that the maintenance work is more convenient, reducing the long-term operation cost.
