Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold bending product technology, and in particular to a feeding guide device for welded pipes. Background Technology
[0002] To ensure the surface quality of cold-bent products, the surface of the raw material coil needs to be protected before and during the forming process to prevent unnecessary scratches.
[0003] In existing feeding devices, guide rollers are mostly installed at the bottom and sides of the raw material coil. The guide rollers rotate synchronously when the raw material coil is conveyed, thereby preventing the raw material coil from contacting the bottom surface of the equipment and causing surface scratches. However, due to the gaps between the guide rollers, during the conveying process of the raw material coil, the head and tail of the material may penetrate into the interior of the vertical roller equipment through the gaps between the guide rollers, resulting in damage to the raw material coil. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a simple and stable feed guide device for welded pipes.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.
[0006] This application provides a feed guide device for welded pipes, comprising:
[0007] Mounting base;
[0008] The idler roller assembly is linearly arrayed and fixedly arranged in multiple groups on the mounting base along a first direction, each group including multiple idler rollers arranged linearly arrayed along a second direction;
[0009] The guide rollers are arranged symmetrically on the mounting base with respect to the multiple sets of idler roller assemblies, and each set includes multiple rollers arranged in a linear array along the second direction.
[0010] Wherein, the gap between the multiple idler roller assemblies in a corresponding group is not greater than the diameter of the idler roller assembly, and the multiple idler roller assemblies in adjacent groups are staggered in the second direction;
[0011] The first direction and the second direction are two perpendicular directions on the horizontal plane. The rotation axis of the idler roller assembly is parallel to the first direction, and the rotation axis of the guide roller is perpendicular to the horizontal plane containing the first direction and the second direction.
[0012] Further specifying, in the above-mentioned feeding guide device for welded pipes, a fixed base is fixedly provided on the end face of the mounting seat away from the ground, and at least one set of the idler roller assembly is fixedly arranged on the fixed base.
[0013] Further specifying, in the above-mentioned feeding guide device for welded pipes, two adjusting bases are symmetrically provided on the end face of the mounting base away from the ground about the fixed base, and the guide roller is rotatably mounted on the adjusting base;
[0014] The adjusting base is provided with at least one set of roller assemblies, and the adjusting base is movable relative to the fixed base in a first direction.
[0015] Further specifying, the above-mentioned feed guide device for welded pipe further includes a drive unit for driving the adjustment base to move relative to the fixed base.
[0016] Further specifying, in the above-mentioned feed guide device for welded pipes, the roller assembly is linearly arrayed along a first direction on the mounting base and fixedly provided in four groups.
[0017] Further specifying, in the above-mentioned feed guide device for welded pipes, the idler roller assembly includes a base and an idler roller body rotatably disposed on the base;
[0018] The outer circular surface of the idler roller body is arc-shaped with a diameter in the middle that is larger than the diameters at both ends.
[0019] Further specifying, in the above-mentioned feeding guide device for welded pipes, the base is provided with a clearance groove located on the side of the roller body near the ground;
[0020] The roller body is located in the relief groove in the radial direction.
[0021] Further specifying, in the above-mentioned feeding guide device for welded pipes, a central shaft is fixedly provided on the base by fixing bolts, and the roller body is sleeved on the central shaft and rotatably connected to the central shaft by bearing components.
[0022] Further specifying, in the above-mentioned feed guide device for welded pipes, two bearing components are provided on the central shaft;
[0023] The two bearing components are located at corresponding positions at both ends of the roller body.
[0024] Further specifying, in the above-mentioned feed guide device for welded pipe, a bushing and an elastic retaining ring are sleeved on the central shaft, and the bushing is located between two bearing components and abuts against the two bearing components respectively;
[0025] A limiting protrusion is fixedly provided on the outer circular surface of the central shaft. One of the bearing components abuts against the limiting protrusion on the side away from the bushing, and the other bearing component abuts against the elastic retaining ring on the side away from the bushing.
[0026] This utility model has at least the following beneficial effects:
[0027] 1. The bottom of the raw material coil is supported by the idler roller assembly, and the side of the raw material coil is limited and guided by the guide roller. When the raw material coil passes through the idler roller assembly and the guide roller, the idler roller assembly and the guide roller roll synchronously and the relative running speed with the surface of the raw material coil is 0, thereby avoiding surface scratches and protecting the surface quality of the raw material coil. At the same time, it also ensures that the equipment is not damaged when the raw material coil is fed. Since the multiple idler roller assemblies in adjacent groups are staggered, they can provide uninterrupted support when the raw material coil is fed, preventing the head or tail of the raw material coil from drilling into the vertical roller equipment and ensuring the stability of the device operation.
[0028] 2. The two adjustable bases that can move relative to the fixed base can be adapted to raw material coils of different specifications. That is, when adjusting the distance between the two sets of guide rollers, it can ensure stable contact and guidance of the side of the raw material coil, which greatly improves the practicality of the device.
[0029] 3. The arc shape of the outer circle of the idler roller body ensures that the middle part of the idler roller body contacts the surface of the raw material coil first, preventing the edge of the idler roller body from making indentations on the surface of the raw material coil.
[0030] 4. By setting the orientation of the clearance groove and the idler body, the overall height of the idler assembly can be reduced, making it easier to use in small spaces. On the other hand, impurities such as iron oxide scale can be discharged through the clearance groove, preventing the accumulation of impurities from affecting the rotation flexibility of the idler body.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0039] The feeding guide device for welded pipes provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0040] like Figures 1 to 4 As shown, this application provides a feeding guide device for welded pipes, including a mounting base 100, multiple sets of idler roller assemblies 200 linearly arrayed along a first direction and fixedly disposed on the mounting base 100, and two sets of guide rollers 300 symmetrically disposed on the mounting base 100 about the multiple sets of idler roller assemblies 200.
[0041] Each group of idler roller assemblies 200 includes a plurality of rollers arranged in a linear array along a second direction. The gap between the plurality of roller assemblies 200 in a corresponding group is no greater than the diameter of the roller assembly 200. The plurality of roller assemblies 200 in adjacent groups are staggered in the second direction.
[0042] Each set of guide rollers 300 includes multiple rollers arranged in a linear array along the second direction.
[0043] The first direction and the second direction are two perpendicular directions on the horizontal plane. The rotation axis of the idler roller assembly 200 is parallel to the first direction, and the rotation axis of the guide roller 300 is perpendicular to the horizontal plane containing the first direction and the second direction.
[0044] In this embodiment, the above-mentioned feeding guide device for welded pipes is used. The bottom of the raw material coil is supported by the idler roller assembly 200, and the side of the raw material coil is limited and guided by the guide roller 300. When the raw material coil passes through the idler roller assembly 200 and the guide roller 300, the idler roller assembly 200 and the guide roller 300 roll synchronously and the relative running speed with the surface of the raw material coil is 0, thereby avoiding surface scratches and protecting the surface quality of the raw material coil. At the same time, it also ensures that the equipment is not damaged when the raw material coil is fed. Since the multiple idler roller assemblies 200 in adjacent groups are staggered, they can provide uninterrupted support when the raw material coil is fed, preventing the head or tail of the raw material coil from entering the vertical roller equipment and ensuring the stability of the device operation.
[0045] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, four sets of idler roller assemblies 200 are linearly arrayed along a first direction on the mounting base 100.
[0046] It is understandable that the number of idler roller assemblies 200 is not limited to the one mentioned above, as long as it can match the width of the raw material roll. This will not be elaborated on here.
[0047] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, a fixed base 110 is fixedly provided on the end face of the mounting base 100 away from the ground, and at least one set of idler roller assemblies 200 are fixedly provided on the fixed base 110.
[0048] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, two adjusting bases 120 are symmetrically arranged on the end face of the mounting base 100 away from the ground about the fixed base 110, and the guide roller 300 is rotatably mounted on the adjusting base 120.
[0049] At least one set of roller assemblies 200 are fixedly provided on the adjusting base 120, and the adjusting base 120 can move relative to the fixed base 110 in a first direction.
[0050] In this embodiment of the application, the above-mentioned feeding guide device for welded pipe is adopted. By using two adjustable bases 120 that can move relative to the fixed base 110, it is possible to adapt to raw material coils of different specifications. That is, when adjusting the distance between the two sets of guide rollers 300, it can ensure stable contact and guidance of the side of the raw material coil, which greatly improves the practicality of the device.
[0051] In a preferred embodiment, a drive unit is also included for driving the adjustment base 120 to move relative to the fixed base 110.
[0052] In a preferred embodiment, the drive unit includes two slide grooves symmetrically arranged on the mounting base 100 about the fixed base 110, two adjusting bases 120 are respectively slidably arranged in the corresponding slide grooves, and a spring is provided between the adjusting base 120 and the groove wall.
[0053] Understandably, when the width of the raw material coil changes, the guide roller 300 adaptively adjusts its position within the chute under the action of the abutment of the side of the raw material coil and the elastic force of the spring, thereby achieving adaptation to the width of the raw material coil.
[0054] It is understandable that the configuration of the drive unit is not limited to the one mentioned above. For example, it can also be set as an electric push rod, which directly controls the relative distance between the two sets of guide rollers 300. As long as it can adapt to the width of the raw material coil, it will not be elaborated here.
[0055] In a preferred embodiment, such as Figures 1 to 3 As shown, the idler assembly 200 includes a base 210 and an idler body 220 rotatably disposed on the base 210.
[0056] The outer circular surface of the idler roller body 220 is arc-shaped with a diameter in the middle that is larger than the diameters at both ends.
[0057] In this embodiment of the application, the above-mentioned feeding guide device for welded pipe is adopted. By setting the outer circle of the roller body 220 in an arc shape, it can be ensured that the middle part of the roller body 220 contacts the surface of the raw material coil first, and prevent the edge of the roller body 220 from causing indentation on the surface of the raw material coil.
[0058] In a preferred embodiment, such as Figures 1 to 4 As shown, the base 210 is provided with a clearance groove 211 located on the side of the roller body 220 near the ground.
[0059] The roller body 220 is located in the relief groove 211 in the radial direction.
[0060] In this embodiment, the above-mentioned feed guide device for welded pipe is adopted. By setting the orientation of the relief groove 211 and the idler body 220, the overall height of the idler assembly 200 can be reduced, making it convenient to use in small spaces. On the other hand, impurities such as iron oxide scale can be discharged through the relief groove 211, preventing the accumulation of impurities from affecting the rotation flexibility of the idler body 220.
[0061] In a preferred embodiment, such as Figures 1 to 3As shown, a central shaft 250 is fixed on the base 210 by fixing bolts 240, and the roller body 220 is sleeved on the central shaft 250 and rotatably connected to the central shaft 250 by bearing 230.
[0062] In a preferred embodiment, such as Figures 1 to 3 As shown, two bearing components 230 are provided on the central shaft 250, and the two bearing components 230 are respectively located at corresponding positions at both ends of the roller body 220.
[0063] In a preferred embodiment, such as Figures 1 to 3 As shown, a bushing 260 and an elastic retaining ring 270 are fitted on the central shaft 250. The bushing 260 is located between two bearing components 230 and abuts against the two bearing components 230 respectively.
[0064] A limiting protrusion 251 is fixedly provided on the outer circular surface of the central shaft 250. One end face of the bearing component 230 away from the bushing 260 abuts against the limiting protrusion 251, and the other end face of the bearing component 230 away from the bushing 260 abuts against the elastic retaining ring 270.
[0065] It is understandable that by the contacting engagement between the limiting protrusion 251, bushing 260, elastic retaining ring 270 and the two bearing components 230, the two bearing components 230 can be positioned relative to the central shaft 250 and the roller body 220, thereby ensuring the rotational smoothness of the roller body 220 and improving the guiding ability of the raw material coil.
