Description

Technical Field

[0001] This invention relates to the field of hardware processing technology, specifically to a roller bending machine for hardware processing. Background Technology

[0002] Some hardware products require the use of industrial machine tools to fold the edges of the plates, and then welding them to form a closed cavity. A medium under a certain pressure is then filled into the cavity. For example, in the manufacture of heat exchanger plates, the folding of the plate edges is usually done manually, that is, by hammering with a hand hammer.

[0003] The invention disclosed in CN104785584A enables the bending of rolled sheets, replacing manual manufacturing with mechanized processes. This significantly improves the production environment, increases production efficiency, and allows for control of bending precision. Furthermore, the improved stress characteristics during the production process control product performance and manufacturing defects.

[0004] However, when the device rotates the lower plate, it needs to continuously move the positions of the conical roller 5 and the cylindrical roller 6 to continuously bend the plate. However, when plates of different lengths and thicknesses are placed on the lower side for bending, the moving speeds of the conical roller 5 and the cylindrical roller 6 are different, and the bending angle of the conical roller 5 on the plate may be different during movement. This may cause the conical roller 5 and the cylindrical roller 6 to be subjected to uneven resistance during extrusion, which may damage the conical roller 5 and the cylindrical roller 6. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a roller bending machine for hardware processing.

[0006] This invention adopts the following technical solution: a roller bending machine for hardware processing, comprising a base and a fixed frame fixed to the upper end of the base. An air pump is fixed to the upper side wall of the fixed frame, a drive motor is fixed to the bottom end of the fixed frame, and a rotating disk is fixed to the output end of the drive motor. The rotating disk is rotatably disposed within the fixed frame. Multiple concentric fixed rings are fixed to the upper end of the rotating disk, with gaps between adjacent fixed rings. Two sliders are horizontally slidably disposed on the upper end of the fixed frame. An electric push rod is fixed to the upper end of each slider. A limit plate and a lifting frame are respectively fixed to the extended ends of the two electric push rods. A cylindrical roller is rotatably disposed within the lifting frame. The invention also includes:

[0007] An automatic triggering mechanism is installed inside the lifting frame to make the sheet metal bend more evenly.

[0008] And a switching mechanism that can automatically change the function of the gas, the switching mechanism being located inside the lifting frame.

[0009] As a further description of the above technical solution: the automatic triggering mechanism includes a conical roller disposed inside the lifting frame, a sliding column movably inserted inside the conical roller, both ends of the sliding column being horizontally inserted inside the lifting frame, a connecting block fixedly connected to one end of the sliding column, the connecting block being horizontally slidably disposed inside the lifting frame, an insert strip movably inserted into the outer wall of the conical roller, an annular block fixedly connected to one end of the insert strip extending to the outside of the conical roller, a pressing rod fixedly connected to one end of the insert strip located inside the conical roller, an inclined sliding surface being provided in the area where the sliding column abuts against the pressing rod, a friction plate being fixedly connected to the outer wall of the slider, the friction plate being in contact with the fixed frame, and an air inlet being provided in the sliding cavity where the slider is located on the side near the air pump, the air inlet being connected to the air pump.

[0010] As a further description of the above technical solution: the switching mechanism includes a connecting block, and a sliding groove is provided at the end of the connecting block away from the sliding column. The sliding groove is opened inside the lifting frame. A connecting groove one and a connecting groove two are opened on the inner wall of the sliding groove. The connecting groove two is set closer to the connecting block than the connecting groove one. An air jet hole is provided on the side of the cylindrical roller away from the conical roller. The air jet hole is opened on the lifting frame and is connected to the connecting groove two. A hose is connected to the lifting frame. One end of the hose is connected to the sliding groove where the slider is located. The connecting groove one is connected to the hose.

[0011] As a further description of the above technical solution: several fixing rings are provided at equal intervals, and the plate can be spirally clamped in the gap.

[0012] As a further description of the above technical solution: the insert is provided in a ring with several equally spaced segments.

[0013] As a further description of the above technical solution: the annular block is provided with an extrusion slope.

[0014] As a further description of the above technical solution: the jet hole faces downwards at an angle.

[0015] As a further description of the above technical solution: only when the connecting block blocks the second connecting groove can the gas ejected from the air inlet push the slider to move.

[0016] This invention provides an improved roller bending machine for metal processing, which has the following improvements and advantages compared with the prior art:

[0017] Firstly, through the setting of automatic triggering and switching mechanisms, the pumped gas can replace other driving sources to move the slider. Furthermore, by changing the air pressure, the movement of the slider can be automatically controlled, ensuring continuous and uniform extrusion of the sheet material with basically equal extrusion angles. This eliminates the need for manual or system control, coordinating the movement of the insert with the rotation of the sheet material. Automatic adjustment also ensures that the force on the conical roller and cylindrical roller is relatively uniform, preventing any one roller from being damaged due to excessive extrusion over a long period of time.

[0018] Secondly, during each automatic adjustment, the gas ejected from the jet nozzle can dissipate heat from the bent sheet, reducing the time required for subsequent cooling. Furthermore, the gas can replace the elastic element to reset the connecting block, reducing operating costs. After subsequent bending is completed, the gas will continue to be ejected from the jet nozzle for automatic heat dissipation, improving overall work efficiency.

[0019] In summary, by setting up automatic triggering and switching mechanisms, the injected gas can replace other driving sources to move the slider. Furthermore, by controlling changes in air pressure, the movement of the slider can be automatically controlled, ensuring continuous and uniform compression of the sheet material at essentially equal angles. This eliminates the need for manual or system control, coordinating the movement of the insert with the rotation of the sheet material. During each automatic adjustment, the gas ejected from the jet nozzles dissipates heat from the bent sheet material, reducing the subsequent cooling time. The gas can also replace elastic components to reset the connecting blocks, lowering operating costs. After subsequent bending, gas continues to be ejected from the jet nozzles for automatic heat dissipation, improving overall work efficiency. Attached Figure Description

[0029] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Please see Figure 1 - Figure 7 This invention provides a technical solution: a roller bending machine for hardware processing, comprising a base 1 and a fixed frame 2 fixed to the upper end of the base 1. An air pump 9 is fixed to the upper side wall of the fixed frame 2, and a drive motor 4 is fixed to the bottom end of the fixed frame 2. A rotating disk 3 is fixed to the output end of the drive motor 4. The rotating disk 3 is rotatably disposed within the fixed frame 2. Multiple concentric fixed rings 12 are fixed to the upper end of the rotating disk 3, with a gap 5 between adjacent fixed rings 12. Two sliders 8 are horizontally slidably disposed on the upper end of the fixed frame 2. Each slider 8 has an electric push rod 6 fixed to its upper end. A limit plate 7 and a lifting frame 10 are respectively fixed to the extended ends of the two electric push rods 6. A cylindrical roller 14 is rotatably disposed within the lifting frame 10. The machine also includes:

[0031] The automatic triggering mechanism 11 can automatically make the board bend more evenly. The automatic triggering mechanism 11 is set inside the lifting frame 10.

[0032] And the switching mechanism 13, which can automatically change the function of the gas, is located inside the lifting frame 10.

[0033] Several fixing rings 12 are provided at equal intervals, and the plate can be spirally locked in the gap 5.

[0034] Specifically, through the automatic triggering mechanism 11 and the switching mechanism 13, the injected gas can replace other driving sources to move the slider 8. Furthermore, by changing the air pressure, the movement of the slider 8 can be automatically controlled, ensuring continuous and uniform extrusion of the sheet material with essentially equal extrusion angles. This eliminates the need for manual or system control, coordinating the movement of the insert 113 with the rotation of the sheet material. During each automatic adjustment, the gas ejected from the jet nozzle 132 can dissipate heat from the bent sheet material, reducing the time required for subsequent cooling. The gas can also replace the elastic element to reset the connecting block 131, reducing operating costs. After subsequent bending, the gas will continue to be ejected from the jet nozzle 132 for automatic heat dissipation, improving overall work efficiency.

[0035] In another embodiment of the present invention, the automatic triggering mechanism 11 includes a conical roller 111 disposed inside the lifting frame 10. A sliding column 112 is movably inserted inside the conical roller 111. Both ends of the sliding column 112 are horizontally inserted inside the lifting frame 10. A connecting block 131 is fixedly connected to one end of the sliding column 112. The connecting block 131 is horizontally slidably disposed inside the lifting frame 10. An insert 113 is movably inserted into the outer wall of the conical roller 111. An annular block 115 is fixedly connected to one end of the insert 113 extending to the outside of the conical roller 111. A pressing rod 117 is fixedly connected to one end of the insert 113 located inside the conical roller 111. An inclined sliding surface 114 is provided in the area where the sliding column 112 abuts against the pressing rod 117. A friction plate 119 is fixedly connected to the outer wall of the slider 8. The friction plate 119 is in contact with the fixed frame 2. An air inlet 1110 is provided on the side of the sliding cavity where the slider 8 is located near the air pump 9. The air inlet 1110 is connected to the air pump 9.

[0036] The insert 113 is arranged in a ring with several equally spaced segments.

[0037] An extrusion slope 116 is provided on the annular block 115.

[0038] Specifically, through the automatic triggering mechanism 11 and the switching mechanism 13, the extracted gas can replace other driving sources to move the slider 8, and through the change of air pressure, the movement of the slider 8 can be automatically controlled, which can ensure continuous and uniform extrusion of the board material, and the extrusion angle is basically equal. It does not require manual or system control to coordinate the movement of the insert 113 with the rotation of the board material.

[0039] In another embodiment of the present invention, the switching mechanism 13 includes a connecting block 131. The end of the connecting block 131 away from the sliding column 112 is provided with a sliding groove 133. The sliding groove 133 is opened in the lifting frame 10. The inner wall of the sliding groove 133 is provided with a first connecting groove 134 and a second connecting groove 135. The second connecting groove 135 is set closer to the connecting block 131 than the first connecting groove 134. The cylindrical roller 14 is provided with a jet hole 132 on the side away from the conical roller 111. The jet hole 132 is opened on the lifting frame 10 and is connected to the second connecting groove 135. A hose 118 is connected to the lifting frame 10. One end of the hose 118 is connected to the sliding groove where the slider 8 is located. The first connecting groove 134 is connected to the hose 118.

[0040] The jet nozzle 132 faces downwards at an angle.

[0041] When the connecting block 131 blocks the connecting groove 135, the gas ejected from the air inlet 1110 can push the slider 8 to move.

[0042] Specifically, during each automatic adjustment, the gas ejected from the jet hole 132 can dissipate heat from the bent sheet material, reducing the time required for subsequent cooling. Furthermore, the gas can replace the elastic element to reset the connecting block 131, reducing operating costs. After subsequent bending is completed, the gas will continue to be ejected from the jet hole 132 for automatic heat dissipation, improving overall work efficiency.

[0043] Working principle: When using this device, the sheet material to be folded is spirally clamped into the gap 5 of the fixing ring 12. Then, the limiting plate 7 is moved down to the upper end of the sheet material to abut against it, preventing the sheet material from moving upward. Then, the lifting frame 10 is moved down by the electric push rod 6, so that the outer wall of the conical roller 111 abuts against the inner side of the upper end of the sheet material, and the insert 113 is pressed into the conical roller 111 by the sheet material. At this time, the insert 113 will drive the pressing rod 117 to press against the inclined sliding surface 114, thereby moving the sliding column 112 and the connecting block 131 toward the connecting groove 135. Then, the connecting block 131 blocks the groove. Connecting slot 2 135, at this time, the air pump 9 is turned on. The air pump 9 draws in from the outside and can no longer be discharged to the outside through the air inlet 1110, hose 118, connecting slot 1 134, connecting slot 2 135 and jet hole 132. At this time, the drawn-in air can gradually increase the gas in the sliding cavity where the slider 8 is located. At this time, the gas pressure is greater than the friction force between the friction plate 119 and the fixed frame 2, which is enough to push the slider 8 and the friction plate 119 to slide. Start the drive motor 4, which in turn drives the rotating disk 3 and the plate to rotate together. Since the plate is placed in a spiral shape, when the plate rotates, it will push the conical roller 11 1. Continuously moving towards the center, if, during movement, due to the different thicknesses of the plates, the plates do not completely abut against the fixing ring 12, causing a small range of sliding relative to the conical roller 111, the pressure exerted by the plates on the insert 113 decreases. Consequently, the gas pushes the connecting block 131 towards the insert 113, thus the connecting block 131 no longer blocks the connecting groove 135, allowing the gas to escape from the connecting groove 135. Finally, the gas is ejected from the jet hole 132. At this point, the gas pressure in the groove where the slider 8 is located is less than the friction force between the friction plate 119 and the fixing frame 2, thus the friction plate... 119 and slider 8 stop moving. After the plate rotates, the pressure between the plate and insert 113 increases again. Insert 113 can automatically block the connecting groove 135, allowing slider 8 to continue moving. This ensures that the movement of slider 8 and conical roller 111 can continuously and evenly compress the plate, and the compression angle is basically equal. It does not require manual or system control. The movement of insert 113 is coordinated with the rotation of the plate and can be automatically adjusted. It also makes the force on conical roller 111 and cylindrical roller 14 more uniform, preventing one of them from being damaged by excessive compression for a long time.

[0044] Furthermore, during each automatic adjustment, the gas ejected from the jet hole 132 can dissipate heat from the bent sheet material, reducing the time required for subsequent cooling. The gas can also replace the elastic element to reset the connecting block 131, reducing the cost of use. After subsequent bending is completed, the gas will continue to be ejected from the jet hole 132 for automatic heat dissipation, improving overall work efficiency.
