Description

Technical Field

[0001] This utility model relates to the field of profile processing equipment technology, specifically a hydraulic profile bending processing device. Background Technology

[0002] Currently, the demand for our ESD products is very high. Conventional plate rolling machines are difficult to process and the precision is hard to control. Similar irregular flat steel bars cannot be processed in single pieces. Two bars need to be spliced ​​and welded together, one for auxiliary processing and the other for processing the useful material. This results in a waste of labor and materials and low work efficiency. Under these circumstances, we developed this hydraulic tooling, which fully meets the needs of on-site profile processing.

[0003] Document CN202022012642 discloses a profile bending processing apparatus, comprising: a support platform; a first drive mechanism disposed on the support platform; a clamping mechanism disposed on the support platform; a pressing mechanism disposed on the support platform; a first bending mechanism disposed on the side of the support platform, the first bending mechanism including a bending rod and a telescopic rod connecting the bending rod; and a second bending mechanism, the second bending mechanism including a second drive mechanism and a turntable mechanically connected to the second drive mechanism, the turntable being provided with a plurality of bending columns. This structure cannot provide appropriate bending fits for profiles of different shapes, and the profiles are easily worn when passing through it.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above problems, this utility model discloses a hydraulic profile bending processing device. Different passive pulleys can be used for profiles of different shapes. The passive pulleys and the top extension processing mold cooperate to perform bending processing on the profile. The anti-deformation correction fixture further performs bending processing on the profile.

[0006] The technical solution of this utility model is as follows: a hydraulic profile bending processing device, including a frame base plate, tooling tables are provided on both sides of the frame base plate along the length direction, a left extension cylinder and a right extension cylinder are provided between the tooling tables, a left extension processing mold and a right extension processing mold are respectively provided inside the left extension cylinder and the right extension cylinder, and two passive pulleys are provided between the left extension processing mold and the right extension processing mold, and anti-deformation correction tooling is provided between the passive pulleys.

[0007] By adopting the above technical solution, the profile is placed between the passive pulley and the top extension processing mold. The top extension processing mold is driven out by the hydraulic cylinder and cooperates with the anti-deformation correction tooling to perform bending processing on the profile.

[0008] Preferably, the left and right extension cylinders are arranged opposite each other and located in their respective housings, and the output ends of the left and right extension cylinders are connected to the left and right extension processing molds, respectively.

[0009] By adopting the above technical solution, when it is necessary to process the profile, the hydraulic cylinder drives the extension processing mold to extend outward to process the profile. After the processing is completed, the extension processing mold retracts.

[0010] Preferably, the left and right extrusion processing molds are half-cylinders, which are half of a cylinder passing through the center of a circle. One side of the rectangular cross-section of the half-cylinder is located at the output end of the hydraulic cylinder, and the other side of the arc-shaped cylinder is set opposite to it.

[0011] By adopting the above technical solution, the curved side of the extrusion mold can be bent.

[0012] Preferably, a lifting guide groove is provided at the bottom between the left and right lifting processing molds, and an anti-deformation correction fixture is provided on the lifting guide groove. The anti-deformation correction fixture is placed on the U-shaped slider and is located between the arcs of the left and right lifting processing molds.

[0013] By adopting the above technical solution, when the anti-deformation correction fixture is not needed, it is placed on the U-shaped slider and slides to the other side on the lifting guide groove, so that the profile is not disturbed.

[0014] Preferably, the anti-deformation correction fixture is a cuboid in shape, with its length parallel to the lifting guide groove. The anti-deformation correction fixture has an inward V-shaped groove on the side facing the semi-cylinder, and the curvature of the V-shaped groove is adapted to the shape of the profile. When not in use, the anti-deformation correction fixture is placed on a U-shaped slider, which is then inverted and slid on the lifting guide groove.

[0015] By adopting the above technical solution, when the profile requires a high degree of curvature, the top-extension processing mold is used in conjunction with the anti-deformation correction fixture. The top-extension processing mold and the anti-deformation correction fixture are located on both sides of the profile at the same position to squeeze and bend it to achieve the desired curvature.

[0016] Preferably, the passive pulleys are located on both sides of the center line between the left and right top-extension processing molds. The passive pulleys have a mounting shaft at their center, which is fixed to the machine frame base plate. The passive pulleys have a through hole at their center that matches the mounting shaft. The passive pulleys and the mounting shaft are detachably connected. The upper surface of the passive pulleys on the mounting shaft is also provided with a mounting cover plate.

[0017] By adopting the above technical solution, the mounting shaft is fixed on the base plate of the frame, and then the passive pulley is sleeved on the mounting shaft. A mounting cover plate is then provided on the passive pulley. The passive pulley and the mounting shaft are rotatably connected. When the profile comes into contact with the passive pulley, the profile can pass through relatively smoothly, preventing burrs and other phenomena from forming on the surface of the profile.

[0018] Preferably, the passive pulley is irregularly shaped, such as a frustum shape (larger at the top and smaller at the bottom), a barbell shape (larger at both ends and smaller in the middle), or a cylinder shape (equal in size at the top and bottom). The side of the passive pulley is the contact surface with the profile, and the bottom of the passive pulley is located below the top surface of the cylinders of the left and right extrusion processing molds.

[0019] By adopting the above technical solution, a passive pulley of the appropriate shape is selected on the mounting shaft according to the different shapes of the profiles, so as to adapt to different profiles.

[0020] The advantages of this utility model are: 1. This utility model has a driven gear that rotates on the mounting shaft and can be replaced according to the actual shape of the profile, which is simple, convenient and quick and has strong adaptability.

[0021] 2. In this utility model, the profile extends into the position between the passive pulley and the top extension processing mold. The left and right top extension processing molds are driven by hydraulic cylinders, which can apply positive and negative pressure to achieve the bending processing of the profile and adjust the size of the arc.

[0022] 3. This utility model uses a passive gear, which is an irregularly shaped processing wheel, to process irregular arc-shaped strip profiles. It can be processed directly on the work site, with high work efficiency, and fully meets the on-site profile processing requirements. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figure 1 As shown, a hydraulic profile bending processing device includes a frame base plate 1. Tooling tables 2 are provided on both sides of the frame base plate 1 along the length direction. A left extension cylinder 3 and a right extension cylinder 4 are provided between the tooling tables 2. A left extension processing mold 5 and a right extension processing mold 6 are respectively provided inside the left extension cylinder 3 and the right extension cylinder 5. Two passive pulleys 11 are provided between the left extension processing mold 5 and the right extension processing mold 6. A reverse deformation correction fixture 9 is provided between the passive pulleys 11. The profile is placed between the passive pulleys 11 and the extension processing mold. The extension processing mold is driven out by the cylinder and cooperates with the reverse deformation correction fixture 9 to perform bending processing on the profile.

[0031] The left extension cylinder 3 and the right extension cylinder 4 are arranged opposite each other and located in the corresponding housing 12. The output ends of the left extension cylinder 3 and the right extension cylinder 4 are connected to the left extension processing mold 5 and the right extension processing mold 6. When the profile needs to be processed, the cylinder drives the extension processing mold to extend outward to process the profile. After the processing is completed, the extension processing mold retracts.

[0032] The left and right extrusion processing molds 3 and 4 are half cylinders. The half cylinder is half a cylinder passing through the center of the cylinder. One side of the rectangular cross-section of the half cylinder is located at the output end of the cylinder, and the curved side of the cylinder is set opposite to it. The curved side of the extrusion mold is exactly facing the bending process.

[0033] A lifting guide groove 7 is provided at the bottom between the left lifting processing mold 5 and the right lifting processing mold 6. An anti-deformation correction fixture 9 is provided on the lifting guide groove 7. The anti-deformation correction fixture 9 is placed on the U-shaped slider 8. The anti-deformation correction fixture 9 is located between the arcs of the left lifting processing mold 3 and the right lifting processing mold 6. When the anti-deformation correction fixture 9 is not needed, it is placed on the U-shaped slider 8 and slides to the other side on the lifting guide groove 7, so that the profile is not disturbed by it.

[0034] The anti-deformation correction fixture 9 is a cuboid in shape. The length of the anti-deformation correction fixture 9 is parallel to the lifting guide groove 7. The anti-deformation correction fixture 9 has an inward V-shaped groove 901 on the side facing the semi-cylinder. The curvature of the V-shaped groove 901 is adapted to the shape of the profile. When the anti-deformation correction fixture 9 is not in use, it is placed on the U-shaped slider 8. The U-shaped slider 8 is placed upside down and slid on the lifting guide groove 7. When the profile requires a high degree of curvature, the lifting processing mold works with the anti-deformation correction fixture 9. The lifting processing mold and the anti-deformation correction fixture 9 are located on both sides of the profile at the same position to squeeze and bend it to achieve the desired curvature.

[0035] The passive pulley 11 is located on both sides of the center line between the left extrusion processing mold 5 and the right extrusion processing mold 6. The passive pulley 11 has a mounting shaft 10 at its center. The passive pulley 11 and the two extrusion processing molds on both sides form a vertical cross shape. The mounting shaft 10 is fixed on the machine frame base plate 1. The passive pulley 11 has a through hole 1101 at its center that matches the mounting shaft 10. The passive pulley 11 and the mounting shaft 10 are detachably connected. The upper surface of the passive pulley 11 on the mounting shaft 10 is also provided with a mounting cover plate 1102. The passive pulley 11 is located symmetrically on both sides of the anti-deformation correction fixture 9. The mounting shaft 10 is fixed on the machine frame base plate 1. Then the passive pulley 11 is fitted onto the mounting shaft 10. The passive pulley 11 is then provided with a mounting cover plate 1102. The passive pulley 11 and the mounting shaft 10 are rotatably connected. When the profile contacts the passive pulley 11, the profile can pass through relatively smoothly, preventing burrs and other phenomena from forming on the surface of the profile.

[0036] The passive pulley 11 is irregularly shaped. It can be a frustum shape (larger at the top and smaller at the bottom), a barbell shape (larger at both ends and smaller in the middle), or a cylinder shape (equal in size at the top and bottom). The shape of the passive pulley 11 includes, but is not limited to, these three shapes. The side of the passive pulley 11 is the contact surface with the profile. The bottom of the passive pulley 11 is located below the top surface of the cylinder of the left and right extrusion processing molds 5 and 6. Depending on the different shapes of the profiles, a passive pulley 11 of the appropriate shape is selected on the mounting shaft 10 to adapt to different profiles.

[0037] For profiles of different shapes, passive pulleys 11 of different shapes can be fitted onto the mounting shaft 10 to accommodate different profiles. If the profile requires a small curvature, the profile can be placed directly between the passive pulley 11 and the top extension processing mold on one side. Then, the hydraulic cylinder lifts the top extension processing mold, and the top extension processing mold performs arc processing on the profile. If the curvature requirement is high, the anti-deformation correction fixture 9 on the U-shaped slider 8 is lifted and placed between the left top extension processing mold 6 and the right top extension processing mold 5. The profile is located on one side of the right V-groove 901 of the anti-deformation correction fixture 9, which can achieve the processing of the profile curvature.
