Description

Technical Field

[0001] The invention relates to the technical field of plate processing, and in particular to an arc track plate folding machine for multi-cavity plates. Background Art

[0002] The plate bending machine is an important equipment for bending and forming workpieces in the sheet metal industry. Its function is to press metal plates into parts of various shapes according to process requirements. For example, the structure of a hydraulic plate bending machine mainly consists of a left and right column, a workbench, and a crossbeam to form a frame. The left and right cylinders are fixed on the columns. The slide is connected to the piston rod of the cylinder and moves up and down along the guide rail fixed on the column. The lower die is fixed on the workbench, and the upper die is installed at the lower end of the slide. The hydraulic system provides power, and the electrical system gives instructions. Under the action of the cylinder, the slide drives the upper die downward and closes the lower die to achieve the bending of the sheet metal.

[0003] With the development of industrial production, thin-walled light steel multi-cavity panels have been widely used in many fields such as construction materials, machinery manufacturing, elevator shafts, and ship transportation.

[0004] However, since thin-walled light steel multi-cavity plates are new types of plates, their structural form is different from that of ordinary metal plates. They have a certain thickness and multi-cavity structure. Traditional bending (plate folding) equipment cannot meet their specific bending requirements, which greatly limits the processing efficiency and construction quality of thin-walled light steel multi-cavity plates. At present, there is no bending equipment suitable for the processing of thin-walled light steel multi-cavity plates on the market. Summary of the invention

[0005] The object of the present invention is to provide an arc track folding machine for multi-cavity plates, which helps to solve the above technical problems.

[0006] The present invention is achieved in that:

[0007] A curved track folding machine for a multi-cavity plate comprises a base, a positioning pressure strip and a swinging tool holder; a folding platform is arranged on the upper part of the base for placing the multi-cavity plate to be bent; the positioning pressure strip is movably arranged on the folding platform for penetrating the plate cavity of the multi-cavity plate to fix the multi-cavity plate; the swinging tool holder is movably arranged on the base and can swing back and forth around an axis parallel to the folding platform to bend the multi-cavity plate.

[0008] Furthermore, the swing tool holder includes a folding plate holder, a first gear, and a driving device; the first gear is arranged on the folding plate holder and driven to rotate by the driving device; an arc-shaped inner gear ring is arranged on the base, and the arc-shaped inner gear ring meshes with the first gear. Its technical effect is that the arc-shaped inner gear ring meshing with the first gear is arranged on the base, and the reaction force of the base can be used to push the component composed of the folding plate holder, the first gear, and the driving device to move along the arc track during the rotation of the first gear to realize the bending operation of the multi-cavity plate.

[0009] Furthermore, the number of the folding plate rack, the first gear, and the arc-shaped inner gear ring is multiple, and the folding plate rack, the first gear and the arc-shaped inner gear ring correspond to each other one by one. The multiple first gears are coaxially arranged and connected to each other by a transmission shaft and a coupling. Its technical effect is that the design of multiple folding plate racks, first gears and arc-shaped inner gear rings can distribute the reaction force of bending the multi-cavity plate to each first gear and arc-shaped inner gear ring in a dispersed manner to increase the processing load of the equipment. At the same time, the design of the transmission shaft and the coupling is conducive to completing the bending of long multi-cavity plates.

[0010] Furthermore, a guide roller is provided on the folding plate frame, and an arc-shaped guide rail is correspondingly provided on the base; during the meshing process between the first gear and the arc-shaped inner gear ring, the guide roller can always clamp the arc-shaped guide rail. The technical effect is that the setting of the guide roller and the arc-shaped guide rail further defines the arc-shaped track of the folding plate frame, ensures the accurate bending of the multi-cavity plate, and increases the service life of the equipment.

[0011] Furthermore, the folding plate frame includes a left clamping plate and a right clamping plate; the first gear is arranged between the left clamping plate and the right clamping plate. The technical effect is that since the first gear is arranged on the folding plate frame and the first gear has a rotating shaft, the folding plate frame is designed as a structure of a left clamping plate and a right clamping plate, and the movable accuracy of the folding plate frame is further improved.

[0012] Furthermore, the swinging tool holder includes a folding plate frame with an arc-shaped outer gear ring on the outer edge; a second gear and a driving device are arranged on the base, and the second gear is driven to rotate by the driving device; the arc-shaped outer gear ring and the second gear are meshed with each other. The technical effect is that the second gear meshing with the arc-shaped outer gear ring is arranged on the base, and the driving device can also be fixedly installed on the base. During the swinging process of the folding plate frame, the second gear and the driving device do not swing with the folding plate frame, which reduces the energy consumption of the equipment and improves the operation stability and service life of the equipment.

[0013] Furthermore, the number of the folding plate rack and the second gear is multiple; the multiple second gears are coaxially arranged and connected to each other by a transmission shaft and a coupling. The technical effect is that the design of the multiple folding plate racks and the second gears can distribute the reaction force of the bending multi-cavity plate to each second gear and the arc-shaped outer gear ring in a dispersed manner to increase the processing load of the equipment. At the same time, the design of the transmission shaft and the coupling is conducive to completing the bending of long multi-cavity plates.

[0014] Furthermore, a guide roller is provided on the folding plate frame, and an arc-shaped guide rail is correspondingly provided on the base; during the meshing process between the second gear and the arc-shaped outer gear ring, the guide roller can always clamp the arc-shaped guide rail. The technical effect is that the setting of the guide roller and the arc-shaped guide rail further defines the arc-shaped track of the folding plate frame, ensures the accurate bending of the multi-cavity plate, and increases the service life of the equipment.

[0015] Furthermore, the swing tool holder is also provided with a movable blade plate; the movable blade plate is arranged at the upper end of the folding plate holder, close to the positioning pressure strip; a plurality of reinforcing ribs are arranged between the movable blade plate and the folding plate holder. The technical effect is that the design of the movable blade plate and the reinforcing ribs can further improve the overall mechanical strength of the swing tool holder, improve the bending accuracy of the multi-cavity plate and the processing load of the equipment.

[0016] Furthermore, the driving device includes a driving motor and a reducer; the driving motor is connected to the first gear through the reducer. The technical effect is that the reducer is used to reduce the rotation speed, increase the torque, and ensure the bending efficiency and quality of the multi-cavity plate. At the same time, the number of driving motors can be reduced through the transmission shaft and the coupling to complete the bending of long multi-cavity plates.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The arc track folding machine for multi-cavity plates of the present invention abandons the extrusion scheme of upper and lower dies adopted in traditional bending equipment, and is the first to introduce a design scheme suitable for bending thin-walled light steel multi-cavity plates. The multi-cavity plates are fixed on the folding platform through the plate cavities by using positioning strips, and the bending of the multi-cavity plates is achieved by swinging the swinging tool holder. It has the advantages of precise bending positioning, low energy consumption, and high processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] First embodiment:

[0030] Figure 1 An axonometric view of the initial state of the arc track folding machine for multi-cavity plates provided by the first embodiment of the present invention; Figure 2 A left side view of the initial state of the arc track folding machine for multi-cavity plates provided by the first embodiment of the present invention; Figure 3 A left side view of the initial state of the arc track folding machine for multi-cavity plates of the first embodiment provided by the present invention (with the left clamping plate 311 removed); Figure 4 An axonometric view of the folding state of the arc track folding machine for multi-cavity plates of the first embodiment provided by the present invention; Figure 5 A left side view of the folding state of the arc track folding machine for multi-cavity plates of the first embodiment provided by the present invention; Figure 6 The left side view of the arc track folding machine for multi-cavity plates of the first embodiment of the present invention is shown in the folding state (without the left clamping plate 311).

[0032] The swinging tool holder 300 includes a folding plate holder 310, a first gear 320, and a driving device; the first gear 320 is arranged on the folding plate holder 310 and driven to rotate by the driving device; the base 100 is provided with an arc-shaped inner gear ring 120, and the arc-shaped inner gear ring 120 is meshed with the first gear 320. In this embodiment, the arc-shaped inner gear ring 120 meshing with the first gear 320 is arranged on the base 100, and the reaction force of the base 100 can be used to push the component integrated with the folding plate holder 310, the first gear 320, and the driving device to move along the arc track during the rotation of the gear 320 to achieve the bending operation of the multi-cavity plate 400.

[0033] It should be noted that the folding plate platform 110 fixes the multi-cavity plate 400 by means of the positioning pressure strip 200, and the position of the positioning pressure strip 200 is the position where the multi-cavity plate 400 needs to be bent. The swing axis of the swing tool holder 300 is close to the positioning pressure strip 200 and is parallel to the positioning pressure strip 200. The multi-cavity plate 400 is bent when the swing tool holder 300 is driven to swing upward.

[0034] The arc track folding machine for multi-cavity plates of this embodiment abandons the extrusion scheme of upper and lower dies used in traditional bending equipment, and is the first to introduce a design scheme suitable for bending thin-walled light steel multi-cavity plates 400. The multi-cavity plates 400 are fixed on the folding platform 110 through the plate cavities using positioning strips 200, and the bending of the multi-cavity plates 400 is achieved by swinging the tool holder 300 along the arc track. It has the advantages of precise bending positioning, low energy consumption, and high processing efficiency.

[0035] Optionally, the folding plate platform 110 may also be disposed on a lower surface of the base 100 , and the swinging tool holder 300 is swung downward to achieve the bending of the multi-cavity plate 400 .

[0036] In the optional solution of the above embodiment, further, as Figure 1 , Figure 4As shown, the number of the folding plate rack 310, the first gear 320, and the arc-shaped inner gear ring 120 are all multiple, and the folding plate rack 310, the first gear 320 and the arc-shaped inner gear ring 120 correspond one to one, and the multiple first gears 320 are coaxially arranged and connected to each other by a transmission shaft and a coupling. In this embodiment, the design of multiple folding plate racks 310, the first gear 320 and the arc-shaped inner gear ring 120 can disperse the reaction force of the bending multi-cavity plate 400 to each first gear 320 and the arc-shaped inner gear ring 120 to increase the processing load of the equipment. At the same time, the design of the transmission shaft and the coupling is conducive to completing the bending of the long multi-cavity plate 400.

[0037] In the optional solution of the above embodiment, further, as Figure 1 to Figure 6 As shown, the folding plate frame 310 is provided with a guide roller 150, and the base 100 is correspondingly provided with an arc-shaped guide rail 130; during the meshing process between the first gear 320 and the arc-shaped inner gear ring 120, the guide roller 150 can always clamp the arc-shaped guide rail 130 during the movement. In this embodiment, the arrangement of the guide roller 150 and the arc-shaped guide rail 130 further defines the arc-shaped track of the folding plate frame 310, ensures the accurate bending of the multi-cavity plate 400, and improves the service life of the equipment.

[0038] In the optional solution of the above embodiment, further, as Figure 1 , Figure 4 As shown, the folding plate frame 310 includes a left clamping plate 311 and a right clamping plate 312; the first gear 320 is arranged between the left clamping plate 311 and the right clamping plate 312. In this embodiment, since the first gear 320 is arranged on the folding plate frame 310 and the first gear 320 has a rotation axis, the folding plate frame 310 is designed as a structure of the left clamping plate 311 and the right clamping plate 312, and the activity accuracy of the folding plate frame 310 is further improved.

During the swinging process of the plate folding frame 310, the second gear 140 and the driving device do not swing with the plate folding frame 310, which reduces the energy consumption of the equipment and improves the operation stability and service life of the equipment.

[0042] At this time, the structure in which the first gear 320 and the arc-shaped inner gear ring 120 mesh with each other in the first embodiment can still be retained, but it is not used as a power mechanism. The first gear 320 is not connected to the driving structure and is only used as a guide to maintain the swing tool holder 300 moving along the arc.

[0043] In the optional solution of the above embodiment, further, as Figure 7 , Figure 8 As shown, the number of the folding plate rack 310 and the second gear 140 are both multiple; the multiple second gears 140 are coaxially arranged and connected to each other by a transmission shaft and a coupling. In this embodiment, the design of the multiple folding plate racks 310 and the second gear 140 can disperse the reaction force of bending the multi-cavity plate 400 to each second gear 140 and the arc-shaped outer gear ring 313 to increase the processing load of the equipment. At the same time, the design of the transmission shaft and the coupling is conducive to completing the bending of the long multi-cavity plate 400.

[0045] In the optional scheme of any of the above embodiments, further, Figure 1 to Figure 8As shown, the swinging tool holder 300 is further provided with a movable blade plate 330; the movable blade plate 330 is arranged at the upper end of the folding plate holder 310, close to the positioning pressure strip 200; and a plurality of reinforcing ribs 340 are arranged between the movable blade plate 330 and the folding plate holder 310. In this embodiment, the design of the movable blade plate 330 and the reinforcing ribs 340 can further improve the overall mechanical strength of the swinging tool holder 300, improve the bending accuracy of the multi-cavity plate 400 and the processing load of the equipment.

[0046] In the optional scheme of the above embodiment, further, the driving device includes a driving motor and a reducer 500; the driving motor is connected to the first gear 320 (in the first embodiment) or the second gear 140 (in the second embodiment) through the reducer 500. In this embodiment, the reducer is used to reduce the rotation speed, increase the torque, and ensure the bending efficiency and quality of the multi-cavity plate 400.
