Description

Technical Field

[0001] The present invention relates to the field of production and processing of wire rod, and particularly to a surface rust removal device and process for wire rod. Background Art

[0002] Wire rod is an important raw material for manufacturing various steel products, wire products (such as wire ropes, wire meshes) and standard parts such as screws and rivets. These products are widely used in the fields of mechanical manufacturing, automobile manufacturing, aerospace, etc.

[0003] During the storage and transportation of wire rod, rust will appear on its surface. Before the wire rod is put into specific use, the surface of the wire rod needs to be polished and rust removed. Traditional polishing and rust removal methods usually use sand belt polishing or wire disc polishing. However, during the use of the polishing equipment, since the cross-section of the wire rod is mostly circular, in order to ensure the polishing quality during polishing, all angles of the wire rod need to be polished. During the process of sand belt polishing, the sand belt not only needs to be in close contact with the side of the wire rod, but also needs to rotate itself and rotate around the wire rod at the same time. This results in a relatively complex structure of the polishing mechanism itself. At the same time, due to the service life problem of the sand belt itself, in order to ensure good polishing quality during use, the sand belt needs to be replaced frequently. For the traditional method of polishing the wire rod with a wire disc, it can only polish one side of the wire rod. In order to ensure the polishing quality, wire disc polishing mechanisms often need to be installed in two directions or even multiple directions. At the same time, the contact distance between the above two methods and the wire rod at a single contact point is very short. In order to ensure the polishing quality, multiple groups of sand belts or multiple groups of wire discs often need to be installed to polish the wire rod. This results in a very long length and a relatively large floor area for the rust removal equipment. Summary of the Invention

The steel wire coil bar is polished by a polishing device. During this process, the polishing device can polish and remove rust at multiple points of the steel wire coil bar in multiple layers of steel wire coil bar constraint grooves. In this way, the rust on the steel wire coil bar can be treated more thoroughly through multiple times of polishing and rust removal. At the same time, the ends of the steel wire coil bars facing the outside in the front and rear steel wire coil bar constraint grooves are opposite, so that all sides of each part of the steel wire coil bar can be polished by the polishing device, thereby ensuring the polishing effect.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention

[0040] To solve the technical problems proposed in the present invention

[0041] As Figures 1 to 10 shown, the present invention provides a surface rust removal device for steel wire coils, including:

[0042] A fixed frame 1, the fixed frame 1 includes two upper and lower fixing plates 11, and the two fixing plates 11 are fixedly connected by metal beams

[0043] Steel wire rod restraint cylinder 2, there are two of the steel wire rod restraint cylinders 2, the steel wire rod restraint cylinders 2 are fixedly connected to the upper fixing plate 11, a spiral steel wire rod restraint groove 21 is provided on the steel wire rod restraint cylinder 2, the steel wire rod restraint groove 21 penetrates through the side surface of the steel wire rod restraint cylinder 2, the starting end of the steel wire rod restraint groove 21 on the front steel wire rod restraint cylinder 2 is located below, the starting end of the rear steel wire rod restraint cylinder 2 is located above, and the end of the front steel wire rod restraint groove 21 is located on the left side, while the starting end of the rear steel wire rod restraint groove 21 is located on the right side;

[0044] Drive cylinder 3, the drive cylinder 3 is rotatably connected in the middle of the steel wire rod restraint cylinder 2;

[0045] Grinding device 4, the grinding device 4 is arranged at the middle position between the two steel wire rod restraint cylinders 2 on the upper fixing plate 11.

[0046] It should be noted that during the use process, the steel wire rod is passed through the steel wire rod restraint groove 21. In this process, first, the steel wire rod is inserted into the starting end of the front steel wire rod restraint groove 21 and passes out from its end along the steel wire rod restraint groove 21. Then, it is inserted into the starting end of the rear steel wire rod restraint groove 21 and finally passes out from the end of the rear steel wire rod restraint groove 21. In this process, the drive cylinder 3 is driven to rotate by a drive device such as a motor. During the rotation of the drive cylinder 3, the steel wire rod is tightened, and under the restraint of the steel wire rod restraint groove 21, it moves in a bolt shape along the steel wire rod restraint groove 21. The steel wire rod is ground by the grinding device 4. In this process, the grinding device 4 can grind and remove rust at multiple points of the steel wire rod in multiple layers of the steel wire rod restraint groove 21. In this way, the rust on the steel wire rod can be treated more thoroughly through multiple times of grinding and rust removal. At the same time, the ends of the steel wire rods facing the outside in the front and rear steel wire rod restraint grooves 21 are opposite, so that all parts of the side surface of the steel wire rod can be ground by the grinding device 4, thereby ensuring the grinding effect.

[0047] Such as Figure 1 and Figure 7 As shown, a steel wire rod winding device 5 is provided at the lower end of the rear steel wire rod restraint cylinder 2. The steel wire rod winding device 5 includes a winding rotating disk 51, a winding frame 52 is fixedly installed on the winding rotating disk 51. The winding frame 52 includes a bottom plate 521. A plurality of winding rods 5212 are fixedly installed circumferentially on the outside of the upper end of the bottom plate 521. The bottom plate 521 and the winding rotating disk 51 are fixedly connected by bolts.

[0048] After the traditional steel wire rod grinding equipment finishes grinding and removing rust from the steel wire rod, it is also necessary to wind up the steel wire rod. Therefore, a winding device for the steel wire rod needs to be installed separately longitudinally, which takes up a lot of space. In the present invention, the steel wire rod can be directly wound up by the winding device. In the present invention, the steel wire rod is already in a curled shape after it breaks away from the steel wire rod restraint cylinder 2. By driving a device such as a motor to drive the rotation of the winding rotating disk 51, the winding rotating disk 51 will drive the rotation of the winding frame 52 during the rotation process, and the winding rod 5212 on the winding frame 52 will wind up the steel wire rod into a disk shape.

[0049] As Figure 1 , Figure 7 and Figure 8 shown, a coaxial linkage device 6 is provided between the rear driving cylinder 3 and the bottom plate 521. The coaxial linkage device 6 includes an intermediate gear 61, a linkage gear 62, and an edge gear 63. A lower end of the rear steel wire rod restraint cylinder 2 is fixedly installed with an extension cylinder 22. A lower end shaft of the rear driving cylinder 3 is fixedly connected with the intermediate gear 61. An edge gear 63 is coaxially and fixedly installed at an upper end of the bottom plate 521. A plurality of linkage gears 62 are circumferentially arranged between the edge gear 63 and the intermediate gear 61. The linkage gear 62 is simultaneously engaged with the intermediate gear 61 and the edge gear 63. The intermediate gear 61 is rotatably mounted on the extension cylinder 22.

[0050] It should be noted that during the process of winding up the steel wire rod, the driving cylinder 3 drives the rotation of the intermediate gear 61. The intermediate gear 61 is engaged with the linkage gear 62 to drive the rotation of the linkage gear 62. The linkage gear 62 is engaged with the edge gear 63 during the rotation process to drive the rotation of the edge gear 63. The edge gear 63 drives the rotation of the winding rotating disk 51 and the winding frame 52 during the rotation process. When the steel wire rod is wound into a disk shape, its diameter is often very large, and the diameters of the bottom plate 521 and the steel wire rod restraint cylinder 2 are different. Therefore, in order to ensure the normal winding of the steel wire rod, the rotational speeds between the two need to be at a reasonable value. During this process, by adjusting the tooth ratio relationship between the intermediate gear 61, the linkage gear 62, and the edge gear 63, the outer speed of the steel wire rod restraint cylinder 2 and the outer speed of the bottom plate 521 are basically kept the same, so that the steel wire rod can be wound up well. Through the above device, the winding work of the steel wire rod can be carried out without occupying much floor area, further reducing the overall floor area used.

[0051] As Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, a plurality of wire guide rods 221 are slidably connected to the extension cylinder 22 along its radial direction. The wire guide rods 221 are evenly distributed in a stepped manner along the circumferential direction of the extension cylinder 22, and the wire guide rods 221 gradually increase in length from top to bottom. The extension cylinder 22 is coaxially rotatably connected with a cooperation disk 222. Corresponding to the wire guide rods 221, cooperation grooves 2221 are formed on the cooperation disk 222. The cooperation grooves 2221 are slidably connected with the wire guide rods 221. A guide groove 2211 is formed at the end of the wire guide rod 221, and a guide roller 2212 is rotatably connected in the guide groove 2211.

[0052] It should be noted that during the process of the wire from the wire coil restraining cylinder 2 to being wound by the winding frame 52, the contour diameter of the wire will change significantly. During this process, the guide roller 2212 on the wire guide rod 221 guides the path of the wire, making the path contour of the wire coil larger and larger, so as to make the winding of the wire coil smoother.

[0053] As Figure 4 and Figure 5 shown, the wire coil restraining cylinder 2 is a shell structure. A dust suction pipe 23 communicating with its interior is connected to the wire coil restraining cylinder 2. A plurality of dust suction holes 211 are formed on the side of the wire coil restraining groove 21 of the wire coil restraining cylinder 2.

[0054] During the process of grinding the wire, a large amount of floating rust particles will be generated, and this phenomenon is more obvious at the direct grinding place of the wire coil. During this process, by generating suction through the dust suction pipe 23, air will flow into the wire coil restraining cylinder 2 from the dust suction holes 211 and enter the dust suction pipe 23 from the wire coil restraining cylinder 2. At this time, the floating rust floating in the air can be treated to a large extent.

[0055] As Figure 10 shown, dense stripes are processed on the outer side of the driving cylinder 3.

[0056] This is to make it not easy to generate relative sliding between the driving cylinder 3 and the wire coil when pulling the wire coil.

[0057] As Figure 2 shown, the grinding device 4 includes a grinding slider 41 and a first grinding rod 42. The grinding slider 41 is slidably connected with the upper fixing plate 11. A first grinding rod 42 is rotatably connected in the grinding slider 41, and a wire grinding wheel is fixedly installed on the first grinding rod 42.

[0058] It should be noted that during the process of grinding the wire rod, the rotation of the first grinding rod 42 is driven by an external driving device such as a motor. During the rotation of the first grinding rod 42, the rotation of the wire grinding wheel is driven. During the rotation of the wire grinding wheel, the wire rod is ground. At the same time, during this process, the movement of the grinding slider 41 can be driven by the hydraulic rod to control the wire grinding wheel to move away from the wire rod, which is convenient for winding the wire rod or pressing the wire rod, thus facilitating the grinding of the wire rod.

[0059] Such as Figure 1 and Figure 9 As shown in the figure, the grinding device 4 includes a second grinding rod 43. The second grinding rod 43 is rotatably connected to the fixing plate 11. The second grinding rod 43 is circumferentially and evenly provided with grinding chutes 431. The grinding chutes 431 are provided along the axial direction of the second grinding rod 43. A plurality of pairs of grinding slides 432 are slidably connected in the second grinding rod 43. A support rod 433 is rotatably connected to the grinding slide 432 at the position of the grinding chute 431. A grinding plate 434 is provided corresponding to the grinding chute 431 on the outer side of the grinding rod. The support rod 433 is hinged to the grinding plate 434. A wire mesh is fixedly installed on the grinding plate 434. An adjusting screw 435 is rotatably connected to the middle position of the second grinding rod 43. The adjusting screw 435 is threadedly connected to the grinding slide 432, and the thread directions of the adjusting screw 435 at the same pair of grinding slides 432 are opposite.

[0060] It should be noted that during the process of grinding the wire rod, the rotation of the second grinding rod 43 is driven by an external driving device such as a motor. During the rotation of the second grinding rod 43, the rotation of the grinding plate 434 and the wire mesh is driven, and the wire rod is ground by using the wire mesh. During this process, the adjusting screw 435 can be rotated to threadedly connect the adjusting screw 435 with the grinding slide 432. The grinding slide 432 will move along the grinding chute 431, and the same pair of grinding slides 432 will move towards each other, so as to control the grinding plate 434 to move radially along the second grinding rod 43, so that the wire rod can be pressed to grind the wire rod.

[0061] Such as Figure 4 and Figure 6 As shown in the figure, the side surface of the wire rod restraint groove 21 is inclined, and one end of the wire rod restraint groove 21 close to the driving cylinder 3 is arc-shaped.

[0062] In this way, under the restraint of the wire rod restraint groove 21, the wire grinding wheel and the wire mesh can be bent towards the side surface of the wire rod, so that they can have a closer contact with the side surface of the wire rod, thereby grinding the wire rod more comprehensively.

[0063] In addition, the present invention also provides a surface rust removal process for steel wire rod, which includes the following steps:

[0064] S1: Pass the steel wire rod through the steel wire rod restraint groove 21. In this process, first pass the steel wire rod into the starting end of the front steel wire rod restraint groove 21, pass through it along the steel wire rod restraint groove 21 from its end, and then pass it into the starting end of the rear steel wire rod restraint groove 21;

[0065] S2: Drive the rotation of the drive cylinder 3 through a driving device such as a motor. During the rotation of the drive cylinder 3, the steel wire rod will be tightened, and it will move in a bolt-like shape along the steel wire rod restraint groove 21 under the restraint of the steel wire rod restraint groove 21;

[0066] S3: Grind the steel wire rod through the grinding device 4. In this process, the grinding device 4 can grind and remove rust at multiple points of the steel wire rod in multiple layers of steel wire rod restraint grooves 21. In this way, the rust on the steel wire rod can be treated more thoroughly through multiple times of grinding and rust removal. At the same time, the ends of the steel wire rods facing the outside in the front and rear steel wire rod restraint grooves 21 are opposite, so that it can be ensured that all parts of the side of the steel wire rod can be ground by the grinding device 4, thereby ensuring the grinding effect.

[0067] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation and specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present invention. In addition, "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0068] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or 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 communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0069] The above has described in detail an embodiment of the present invention, but the above content is only a preferred embodiment of the present invention and cannot be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made in accordance with the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
