Description

Technical Field

[0001] The present application relates to the technical field of wire rod descaling, and in particular to a wire rod knotting detection device and a wire rod descaling device. Background Art

[0002] As an important consumable material for manual arc welding, the quality of the welding core of the welding rod directly affects the performance of the welded joint. The welding core of the welding rod usually exists in the form of wire rod before processing. Wire rod refers to a metal wire with a certain diameter and length made by hot rolling or cold drawing.

[0003] During the production process of wire rod, due to the limitations of smelting and rolling processes, a layer of oxide scale, commonly known as scale, often adheres to the surface of the wire rod. These scales not only affect the welding performance of the electrode, but may also cause defects such as pores and cracks during the welding process, so they need to be effectively removed.

[0004] At present, during the wire rod conveying process, a wire rod descaling machine is often used to remove the iron oxide scale on the wire rod surface, for example, the wire rod descaling machine disclosed in the application publication number CN102756001A. However, when the wire rod is knotted, the knot position of the wire rod is often blocked by the wire rod descaling machine, causing the wire rod to stagnate. If the on-site staff fails to discover this situation in time, the entire production line will stagnate for a long time, and in serious cases, safety accidents will occur. Utility Model Content

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0050] It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the embodiments and features in the embodiments of this application can be combined with each other without conflict.

[0051] In the description of the embodiments of the present application, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or is the orientation or positional relationship in which the product of the application is usually placed when in use, or is the orientation or positional relationship commonly understood by those skilled in the art. The terms "disposed", "opened", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, and an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements.

[0052] See also Figure 1A wire rod knotting detection device provided in an embodiment of the present application includes a mounting frame 61, on which a movable seat 62 is provided. The movable seat 62 can reciprocate in a vertical direction relative to the mounting frame 61, and the movable seat 62 has a vertically arranged through hole 621 for the wire rod 9 to pass through. The movable seat 62 is connected to a sensing disk 63, and the mounting frame 61 is provided with a photoelectric detector 64 that cooperates with the sensing disk 63 for detection, and the photoelectric detector 64 is used to be connected to the controller of the production line.

[0053] The mounting frame 61 is used to be mounted on the frame of the production line. The movable seat 62 is arranged on the mounting frame 61 and can reciprocate in the vertical direction on the mounting frame 61. The center of the movable seat 62 has a through hole 621 vertically penetrating the through hole 621. The diameter of the through hole 621 is larger than the outer diameter of the wire rod 9 so that the wire rod 9 can pass through the through hole 621. The diameter of the through hole 621 is smaller than the size of the knotted position of the wire rod 9 so that the knotted position of the wire rod 9 cannot pass through the through hole 621. During the production process, the wire rod 9 passes through the through hole 621 and is transported in a direction from bottom to top. If the wire rod 9 is not knotted, the position of the movable seat 62 does not change. If the wire rod 9 is knotted, when the knotted position of the wire rod 9 contacts the lower end of the movable seat 62, the wire rod 9 drives the movable seat 62 to move upward, so that the position of the movable seat 62 changes.

[0054] The induction disk 63 is connected to the movable seat 62, and the photoelectric detector 64 is connected to the mounting frame 61. The induction disk 63 cooperates with the photoelectric detector 64 to detect the position of the movable seat 62. When a change in the position of the movable seat 62 is detected, it indicates that the wire rod 9 is knotted. At this time, the photoelectric detector 64 sends a signal of the knotting of the wire rod 9 to the controller of the production line. The controller of the production line controls the production line to stop, so that the staff at the production site can promptly discover the knotting of the wire rod 9, so as to facilitate timely disposal of the knotting of the wire rod 9 and resume the operation of the production line as soon as possible.

[0055] There are two main ways of cooperating between the induction disk 63 and the photoelectric detector 64. The first is: in the initial state, the induction disk 63 is just within the detection range of the photoelectric detector 64. When the movable seat 62 drives the induction disk 63 to move upward, the induction disk 63 can be out of the detection range of the photoelectric detector 64. At this time, the photoelectric detector 64 can detect that the position of the movable seat 62 has changed, which further indicates that the wire rod 9 is knotted. The second is that in the initial state, the induction disk 63 is just outside the detection range of the photoelectric detector 64. When the movable seat 62 drives the induction disk 63 to move upward, the induction disk 63 can enter the detection range of the photoelectric detector 64. At this time, the photoelectric detector 64 can detect that the position of the movable seat 62 has changed, which further indicates that the wire rod 9 is knotted. Among them, the photoelectric detector 64 can adopt existing products and be purchased directly on the market. Exemplarily, the photoelectric detector 64 can be an infrared photoelectric detector.

[0056] See also Figure 1 The wire rod knotting detection device provided in the embodiment of the present application is used to be arranged on the production line to detect the knotting condition of the wire rod before the wire rod is descaled. The specific detection process is as follows: the mounting frame 61 is installed on the frame of the production line. In the initial state, the sensing disk 63 is just located within the detection range of the photoelectric detector 64. The wire rod 9 passes through the through hole 621 of the movable seat 62 and is conveyed in the direction from bottom to top. If the wire rod 9 is knotted, when the knotted position of the wire rod 9 contacts the lower end of the movable seat 62, the wire rod 9 drives the movable seat 62 and the sensing disk 63 to move upward. When the sensing disk 63 leaves the detection range of the photoelectric detector 64, the photoelectric detector 64 sends a signal of the knotting of the wire rod 9 to the controller of the production line, and the controller of the production line controls the production line to stop.

[0057] The wire rod knot detection device provided in the embodiment of the present application, when the photoelectric detector 64 and the induction disk 63 are used to detect that the wire rod 9 is knotted, the photoelectric detector 64 sends a signal to the controller of the production line to control the production line to stop, thereby reminding the on-site staff that the wire rod 9 is knotted, so that the on-site staff can deal with the knotting of the wire rod 9 in time to resume the operation of the production line as soon as possible, avoiding the situation where the staff fails to discover the knotting of the wire rod in time and causes the production line to stagnate for a long time.

[0058] The movable seat 62 can be slidably mounted on the mounting frame 61 through a guide mechanism consisting of a guide rail and a slider, so that the movable seat 62 moves upward under the action of an external force, and moves downward under the action of gravity after the external force is removed.

[0059] In some embodiments, see Figure 1 The mounting frame 61 is connected to a vertically arranged fixed tube 65 which is sleeved on the outside of the movable seat 62 . Both ends of the movable seat 62 are located outside the fixed tube 65 and are respectively connected to limit blocks 66 , one of which forms a sensing disk 63 .

[0060] Exemplarily, the fixed tube 65 is vertically arranged and fixedly connected to the mounting frame 61, the movable seat 62 is a vertically arranged movable tube, the inner hole of the movable tube forms a through hole 621, and the outer diameter of the movable tube is smaller than the inner diameter of the fixed tube 65, so that the movable tube can be movably arranged in the fixed tube 65. The length of the movable tube is greater than the length of the fixed tube 65. When the movable tube is arranged in the fixed tube 65, the two ends of the movable tube are respectively located outside the fixed tube 65, and the outer walls of the two ends of the movable tube are respectively connected to limit blocks 66, and the two limit blocks 66 are respectively limited with the two ends of the fixed tube 65 to prevent the movable tube from being separated from the fixed tube 65. Among them, the limit block 66 at the upper end of the movable tube forms an induction plate 63. Of course, the limit block 66 at the lower end of the movable tube can also form an induction plate 63.

[0061] The mounting frame 61 may be a frame structure made of steel. In some embodiments, the mounting frame 61 includes an upper mounting ring 611 disposed above the movable seat 62, a lower mounting ring 612 disposed below the movable seat 62, and a connecting rod 613 connected between the upper mounting ring 611 and the lower mounting ring 612.

[0062] Exemplarily, the upper mounting ring 611 and the lower mounting ring 612 are both horizontally arranged circular rings, the outer diameter of the upper mounting ring 611 is smaller than the outer diameter of the lower mounting ring 612, and the upper mounting ring 611 and the lower mounting ring 612 are connected by a plurality of connecting rods 613 evenly arranged around the circumference, thereby making the mounting frame 61 generally present a frustum-shaped structure with a small top and a large bottom, which is simple in structure, stable and reliable. The fixing tube 65 is arranged between the upper mounting ring 611 and the lower mounting ring 612, and is fixedly connected to the lower mounting ring 612 by a plurality of supporting rods 616 evenly arranged around the circumference.

[0063] In order to facilitate the connection between the mounting frame 61 and the rack of the production line, in some embodiments, see Figure 1 , connecting arms 614 extending upward are connected to both sides of the upper mounting ring 611, and a guide ring 615 for the wire rod 9 to pass through is installed between the two connecting arms 614. During installation, the upper ends of the two connecting arms 614 are connected to the frame by bolts. By providing the guide ring 615, the wire rod 9 can pass through the guide ring 615 for transportation, which can not only guide the wire rod 9, but also reduce the swing amplitude of the wire rod 9 during transportation.

[0064] See also Figure 2 An embodiment of the present application provides a wire rod descaling device, including a frame 1, on which is provided a descaling wheel group 2 and a first wire wheel 3 located on the wire inlet side of the descaling wheel group 2. The frame 1 is also provided with a support arm 4 extending obliquely upward from the direction from the descaling wheel group 2 to the first wire wheel 3. The upper end of the support arm 4 is connected to a second wire wheel 5 and a detection device 6 located below the second wire wheel 5. The detection device 6 is the wire rod knotting detection device provided in the above embodiment.

[0065] The frame 1 can be a frame structure composed of steel, which is used to be installed on the basis of the production line. The descaling wheel group 2 is installed on the frame 1, and is used to bend the wire rod 9 during the production process so that the oxide scale on the surface of the wire rod 9 falls off to achieve the descaling effect. The first wire wheel 3 is arranged on the inlet side of the descaling wheel group 2 and installed on the frame 1, and is used to guide the wire rod 9 so that the wire rod 9 can smoothly enter the descaling wheel group 2. The support arm 4 is installed on the frame 1 and arranged obliquely, and is used to install the second wire wheel 5 and the detection device 6. The second wire wheel 5 is installed at the upper end of the support arm 4, and is used to guide the wire rod 9. The detection device 6 is installed at the upper end of the support arm 4 and is located below the second wire wheel 5, which not only allows the detection device 6 to have a certain installation height, which is convenient for placing the wire rod 9 below it, but also can detect the knotting of the wire rod 9. Exemplarily, the mounting frame 61 of the detection device 6 is connected to the upper end of the support arm 4. Specifically, the upper mounting ring 611 or the connecting arm 614 is connected to the upper end of the support arm 4.

[0066] The working principle of the wire rod descaling device provided in the embodiment of the present application is as follows: Figure 2 The wire rod 9 first passes through the detection device 6, then bypasses the second wire wheel 5 and the first wire wheel 3 in sequence, and then passes through the descaling wheel group 2 for transportation on the production line. During this process, the detection device 6 is used to detect the knotting condition of the wire rod 9, the second wire wheel 5 and the first wire wheel 3 are used to guide the wire rod 9 and change the transportation direction, and the descaling wheel group 2 is used to remove the oxide scale on the surface of the wire rod 9.

[0067] The wire rod descaling device provided in the embodiment of the present application can not only utilize the descaling wheel group 2 to remove the oxide scale on the surface of the wire rod 9 to achieve the descaling effect, but also utilize the detection device 6 to detect the knotting condition of the wire rod 9 before descaling, and after detecting the knotting of the wire rod 9, send a signal to the controller of the production line to control the production line to stop, thereby achieving the effect of alarm stopping, so that on-site staff can deal with the wire rod knotting condition in time to resume the operation of the production line, and avoid the situation where the staff fails to discover the wire rod knotting in time and causes the production line to stagnate for a long time.

[0068] In some embodiments, see Figure 2 The support arm 4 is hinged to the frame 1, and a driving mechanism 7 is connected between the support arm 4 and the frame 1, and the driving mechanism 7 is used to drive the support arm 4 to flip up and down. When in use, the driving mechanism 7 drives the support arm 4 to rotate, and then the height of the detection device 6 can be adjusted to meet the requirements of different heights.

[0069] Exemplarily, the driving mechanism 7 may include a linear drive such as a hydraulic cylinder, a pneumatic cylinder or an electric push rod, and the two ends of the driving mechanism 7 are respectively hinged to the support arm 4 and the frame 1. The two ends of the support arm 4 are respectively located on both sides of the hinge position of the support arm 4 and the frame 1. In order to balance the weight of the detection device 6, a counterweight 41 is connected to the lower end of the support arm 4, thereby reducing the driving force for driving the support arm 4 to flip up and down.

[0070] In some embodiments, see Figure 1 , Figure 2 , Figure 3 A wire passer 8 is provided on the frame 1 at the wire inlet side adjacent to the descaling wheel group 2, and the wire passer 8 has a wire hole 81 for the wire rod 9 to pass through. During the production process, the wire rod 9 passes through the wire hole 81 after passing around the first wire wheel 3, and then passes through the descaling wheel group 2 for descaling. The wire passer 8 is provided to accurately position the wire rod 9 on the wire inlet side of the descaling wheel group 2, so that the wire rod 9 accurately enters the descaling wheel group 2 from the wire inlet side of the descaling wheel group 2 for descaling, avoiding the situation where the wire rod 9 is separated from the descaling wheel group 2 due to inaccurate positioning, thereby ensuring the continuity of the production line.

[0071] In some embodiments, see Figure 2 , Figure 3 The descaling wheel group 2 includes a first descaling wheel 21, a second descaling wheel 22, a third descaling wheel 23, a fourth descaling wheel 24 and a fifth descaling wheel 25 which are sequentially arranged along the conveying direction of the wire rod. During the production process, the wire rod 9 passes through the first descaling wheel 21, the second descaling wheel 22, the third descaling wheel 23, the fourth descaling wheel 24 and the fifth descaling wheel 25 in sequence. The wire rod 9 is repeatedly bent by the five descaling wheels during the conveying process, so that the oxide scale on the surface of the wire rod 9 falls off, achieving the descaling effect.

[0072] In some embodiments, see Figure 2 , Figure 3 The center lines of the first descaling wheel 21 , the second descaling wheel 22 and the fifth descaling wheel 25 are parallel, the center lines of the third descaling wheel 23 and the fourth descaling wheel 24 are parallel, and the center lines of the first descaling wheel 21 and the third descaling wheel 23 are perpendicular.

[0073] Exemplarily, the center lines of the first descaling wheel 21, the second wire wheel 5 and the first wire wheel 3 are parallel. The height of the first descaling wheel 21 is consistent with that of the second descaling wheel 22, and the second descaling wheel 22, the third descaling wheel 23, the fourth descaling wheel 24 and the fifth descaling wheel 25 are arranged at intervals from bottom to top. In this way, the bending direction of the wire rod 9 can be changed in three-dimensional space, further improving the descaling effect.

[0074] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiments shall still fall within the protection scope of the technical solution of the present application.
