Description

Technical Field

[0001] The utility model relates to the technical field of online processing equipment for glass fiber reinforced plastic pultruded profiles, and in particular to a clamp-type position limiting correction device with adjustable distance. Background Art

[0002] FRP channel steel (pultruded channel steel, pultruded profile) is made of alkali-free untwisted glass fiber roving, which is warped and impregnated with polyester resin for continuous pultrusion and heat curing. It has high mechanical and insulation properties and can be processed into different shapes for use in various fields, bringing many conveniences to industry and production processing.

[0003] The pultrusion of FRP composite materials is affected by the cross-sectional shape of the product, the stress of fiber yarn and fiber felt cloth, and warping and deformation will occur after leaving the mold cavity. The existing problems are: using the mold cavity pre-deformation correction requires rich experience and continuous correction, the process is complicated, and the adjustment time is long. After extrusion molding, the shape accuracy is usually inaccurate due to the wide shape structure, and after transportation, it is necessary to manually adjust the shape again to achieve the surface correction of the FRP pultruded profile. However, this correction method is not only difficult to ensure the uniform shape accuracy of all FRP pultruded profiles, but also cannot be flexibly adjusted for FRP pultruded profiles of different shapes and sizes, resulting in a single correction shape. Utility Model Content

[0004] The utility model aims to provide a clamping type limit correction device with adjustable distance, which is used to solve the technical problems of large deformation and difficult adjustment of profiles produced by the existing pultrusion process.

[0005] The basic scheme provided by the utility model is: a clamp-type position limiting correction device with adjustable distance, comprising at least one correction component; the correction component comprises two guide members, a rotating rod, at least two correction ring groups and two fasteners;

[0006] The guide member comprises a U-shaped body with a sealing plate at at least one end, wherein the sealing plate is provided with a mounting hole, and a strip hole is provided on a side of the U-shaped body opposite to the opening; the rotating rod passes through the strip hole and can be rotatably installed between the two guide members; the at least two groups of correction ring groups are coaxially installed on the rotating rod at a preset distance; the correction ring group comprises two annular columns, wherein there is a spacing between the two annular columns; the fastener comprises a first screw rod; the screw rod passes through the mounting hole of the guide member and is connected to the end of the rotating rod in a preset manner.

[0007] Furthermore, the rotating rod includes a cylindrical body; bearings are installed at both ends of the cylindrical body; a second screw is installed at the center of the bearing away from the cylindrical body; and matching nuts are provided on both sides of the second screw.

[0008] Furthermore, a fastening screw is installed on the correction ring.

[0009] Furthermore, the correction ring is made of 3240 epoxy material.

[0010] Furthermore, the annular column has a ring width of 10-20 mm and a column height of 20-30 mm.

[0015] Furthermore, the preset method is to abut the first screw against the outer end nut.

[0016] The working principle and advantages of the utility model are as follows: the product corrected by the correction device of this scheme is generally pultruded channel steel, and the correction position is the notch. The pultruded channel steel is conveyed on the working platform, and the edge of the notch is limited by the spacing between two annular columns for correction and adjustment. At the same time, as the channel steel is conveyed, the edge of the channel steel contacts the cylindrical body of the rotating rod, and rotates synchronously under the action of the bearing, and the annular column also rotates synchronously with the rotating rod, thereby reducing contact friction and ensuring product quality; during the correction process, the fastener applies force to the end of the rotating stem by welding or abutment to ensure the stability of the rotating rod and prevent displacement. According to the size of the channel steel, adjust the installation position of the rotating rod in the strip hole so that the height of the rotating rod is adapted to the height of the surface to be corrected of the product; adjust the spacing of the correction ring group to adapt to the width of the notch; adjust the spacing of the annular columns to adapt to the thickness of the channel steel, so as to achieve the purpose of being able to adjust the molded product up, down, left, and right.

[0017] The single correction component of this solution has a simple structure, and the spacing positions can be flexibly adjusted to adapt to products of different specifications, different production modes, and different position correction requirements. At the same time, according to the situation of the production line, multiple sets of correction components can be flexibly matched to perform correction at the same time, which can meet a variety of production scenarios and has strong versatility. In addition, the rotating rod and the correction ring group can be rotatably set with the rotating rod, which can reduce contact friction during the correction process, reduce product wear, and ensure product quality.

[0022] The following is a further detailed description through specific implementation methods:

[0023] The marks in the drawings of the specification include: guide member 1, U-shaped body 11, sealing plate 12, strip hole 13, rotating rod 2, cylindrical body 21, bearing 22, second screw 23, outer end nut 24, inner end nut 25, annular column 3, fastening screw 31, first screw 4, channel steel 5.

[0024] The embodiment is basically as shown in the attached Figure 1 As shown: a distance-adjustable clamp-type position limiting correction device includes at least one correction component; the correction component includes two guide members 1, a rotating rod 2, at least two correction ring groups and two fasteners. The correction object is generally a product with a notch, such as a channel steel 5, but it is not limited to this. This embodiment is only described with a channel steel 5 with a notch.

[0025] The guide member 1 includes a U-shaped body 11 with a sealing plate 12 at at least one end. The U-shaped body 11 is 600-650 mm long and 50-60 mm wide. It adopts a steel structure and can provide stable support. The other end may be sealed or not. Because when using this tooling, the guide member 1 is fixedly installed on the production line work platform and can be reasonably set according to actual assembly needs.

[0026] like Figure 2 and Figure 3 As shown, a strip hole 13 is formed on one side of the U-shaped body 11 relative to the opening, and the length of the strip hole 13 is 400-500 mm. Such a data range can adapt to the height adjustment needs of various specifications of correction products. The sealing plate 12 has a mounting hole with a hole diameter of 22-25 mm, which can be adapted to the installation of fasteners.

[0027] The rotating rod 2 includes a cylindrical body; bearings 22 are installed at both ends of the cylindrical body. The cylindrical body is a hollow structure, and steps are provided at both ends to position the bearings on the left and right. The outer circle of the bearing and the inner circle of the cylindrical body are interference fit to tighten the bearings; away from the cylindrical body, a second screw 23 is installed at the center of the bearing 22, and the second screw is also provided with steps to position the bearings on the left and right. The inner circle of the bearing and the outer circle of the second screw are interference fit to tighten the bearings. The second screw 23 is provided with matching outer end nut 24 and inner end nut 25. In this way, the second screw passes through the strip hole 13 and cooperates with the inner and outer end nuts 24 to fix the rotating rod 2 between the two guide rods. The cylindrical body 21 can rotate under the action of the bearing 22, so that the rotating rod 2 can pass through the strip hole 13 and be rotatably installed between the two guide members 1. In this embodiment, the length of the cylindrical body is 1100-1150mm and the diameter is 50-60mm; the length of the second screw 23 is 1200-1300mm and the diameter is 14-18mm; such a size combination is compatible with the product specifications and weight and other characteristics, and can achieve stable and effective installation of the rotating rod 2 between the guide members 1. It can also effectively bear the weight of the product during the product correction process. At the same time, the rotating rod 2 can effectively rotate as the corrected product moves up and down, and finally achieve the purpose of correcting the rigid extrusion die product.

[0028] like Figure 3 and Figure 4 As shown, the at least two sets of correction ring groups are coaxially installed on the rotating rod 2 at a preset distance. The setting of the preset distance is adapted to the correction product, such as the slot width of the channel steel 5. The preset distance d1 is 0-1000mm, which can be adapted to a variety of specifications and can also achieve the purpose of left and right adjustment of the just-molded product; when d1 is 0, the slot size of the channel steel suitable for correction is determined by the height of the two correction columns on both sides, that is, the slot width can be 40-60mm.

[0029] The correction ring set includes two annular columns 3, wherein there is a spacing between the two annular columns 3, and the spacing is adapted to the correction product, such as the notch edge size of the channel steel 5. The annular column 3 can be made of 3240 epoxy material. The radial cross-section of the annular column is annular, and a column structure is formed after the annular axial stretching is a certain height. The ring width is defined by the difference between the radial outer ring radius and the inner ring radius, and the column height is defined by the axial height. The ring width of the annular column 3 is 10-20mm, and the column height is 20-30mm. The spacing d2 is 2-20mm. A fastening screw 31 is installed on the cylindrical surface of the annular column 3. The fastening screw is tightened after the preset distance d1 and the spacing d2 are determined according to the product structure.

[0030] The fastener includes a first screw rod 4 and a matching nut thereof; the first screw rod 4 passes through the mounting hole of the guide member 1 and is connected to the end of the rotating rod 2 in a preset manner. The first screw rod 4 has a length of 500-550 mm and a diameter of 18-20 mm, which is matched with the mounting hole and the length of the guide member.

[0031] The preset method is to weld the first screw rod 4 to the outer end nut 24 or to abut the first screw rod 4 against the outer end nut 24 .

[0032] The specific use process of this tool is as follows:

[0033] The product to be corrected by the correction device of this scheme is generally a pultruded channel steel 5, and the correction position is the notch. Two guide members 1 are fixedly installed on both sides of the working platform of the pultrusion production line, and the rotating rod 2 is horizontally installed between the two guide rods through the strip hole 13. According to the size of the channel steel 5, the installation position of the rotating rod 2 in the strip hole 13 is adjusted so that the height of the rotating rod 2 is adapted to the height of the surface to be corrected of the product; when the notch is upward during correction, the rotating rod 2 is installed at a high place, and the channel steel 5 is located below the rotating rod 2. At this time, the first screw 4 abuts against the end of the rotating rod 2, that is, the outer end nut 24, to provide a downward force to the rotating rod 2, stabilize the rotating rod 2, and avoid upward displacement during the transmission of the channel steel 5; when the notch is downward during correction, the rotating rod 2 is installed at a low place, and the channel steel 5 is located above the rotating rod 2. At this time, the first screw 4 is welded to the end of the rotating rod 2, that is, welded to the outer end nut 24, to provide an upward force to the rotating rod 2, stabilize the rotating rod 2, and avoid downward displacement of the rotating rod 2 due to the weight and movement of the channel steel 5 during the transmission of the channel steel 5. Adjust the spacing of the correction ring group to match the width of the slot; adjust the spacing of the annular column 3 to match the thickness of the channel steel 5, and at the same time, fasten the annular column 3 to the rotating rod 2 through the fastening screws 31 of the annular column 3.

[0034] The pultruded channel steel 5 is conveyed on the working platform, and the edge of the groove passes through two annular columns 3. The distance between the two annular columns 3 is used for clamping limiting and correction adjustment. At the same time, as the channel steel 5 is conveyed, it contacts the cylindrical body 21 of the rotating rod 2. The cylindrical body 21 rotates synchronously under the action of the bearing 22, and the annular column 3 also rotates synchronously with the rotating rod 2, thereby reducing contact friction and ensuring product quality.

[0035] The number of groups and the spacing between groups of components can be adjusted according to the actual production line layout, so that multi-point calibration can be performed on the calibration products on the production line to ensure product accuracy.

[0036] The present embodiment provides a distance-adjustable clamp-type limit correction device. The single correction component has a simple structure, and multiple spacing positions can be flexibly adjusted to adapt to different specifications of products and different production modes and different position correction requirements. At the same time, according to the production line conditions, multiple groups of correction components can be flexibly matched for simultaneous correction, which can meet a variety of production scenarios and has strong versatility. In addition, the rotating rod and the correction ring group can be rotatably set with the rotating rod, which can reduce contact friction during the correction process, reduce product wear, and ensure product quality. The corrected channel steel can meet the customer's requirements for product size accuracy.
