Description

Technical Field

[0001] This utility model relates to the field of door frame production, and in particular to a bending device for door frame production. Background Technology

[0002] A door frame is a device used to prevent the wall next to the door from collapsing and to support the door panel. When using metal materials to make door frames, in order to save materials, the door frame is made hollow. Usually, the metal is made into a thin sheet with tensile properties, and then it is placed on the lower die of a frame pressing machine. The frame pressing machine is then started, and the upper die of the frame pressing machine presses on it, thus creating a bend. To make a door frame from a thin sheet, the sheet needs to be bent multiple times. After each bend, the upper die needs to be returned, and then the sheet is moved until the bending of the sheet meets the technical requirements.

[0003] Currently, some door frame bending equipment still has certain shortcomings in use: First, some bending equipment sets the positioning structure on the inside of the frame, and a support structure is specially set on the side where the worker stands, so that the worker can place the board on it before operation or during the gap when the upper die retracts, without having to lift it by hand all the time. However, some door panels are long, and when the worker flips them, the support structure will block the door panel, so that the worker needs to step outside the support structure to operate, or use his arm to lift the door panel to operate, which is more troublesome and inconvenient.

[0004] Secondly, current bending equipment is inconvenient for workers to quickly feed and unload materials, resulting in low overall processing efficiency.

[0005] Therefore, it is necessary to provide a new bending equipment for door frame production to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a bending device for door frame production that allows workers to quickly pick up and put down materials, while the supporting structure can be folded.

[0007] To solve the above-mentioned technical problems, the present invention provides a bending equipment for door frame production, comprising: a frame, a placement component, and a support structure. The frame has a positioning structure installed inside, and a bending structure installed on the top of the frame. The placement component is provided in two sets and is located on the left and right sides of the frame respectively. The placement component includes two supports, which are distributed left and right and are rotatably connected to each other by a lead screw. A drive motor is fixedly connected to the surface of one of the supports, and the output end of the drive motor is fixedly connected to one end of the lead screw. A movable part is sleeved on the surface of the lead screw, and the tops of the two movable parts are respectively fixedly connected to a first placement frame and a second placement frame through support rods.

[0008] The support structure includes two support members, each hinged to the front wall surface of the frame. An electric push rod is hinged between the support member and the frame. A foot switch is located at the front of the frame and is electrically connected to the electric push rod.

[0009] As a further embodiment of this utility model, positioning rods are fixedly connected to the support surfaces on both the front and rear sides of the lead screw, the positioning rods are slidably connected to the movable parts, and the lead screw is threadedly connected to the movable parts.

[0010] Through the above technical solution, in this device, after the user bends the sheet material into the desired shape using the bending structure, they can start the two drive motors on both sides through the operation panel on the frame. The drive motors can drive the lead screw to rotate, thereby causing the two sets of moving parts to move synchronously toward the user. The user can place the bent material on the first placement rack, and then take a new sheet material from the second placement rack. Afterwards, the drive motor is started again to make the moving parts return to their original position, avoiding the structure's position from affecting the user's ability to flip the sheet material. This structural design allows the user to place and take materials without repeatedly leaving the frame, making it easier and more efficient.

[0011] As a further embodiment of this utility model, a suction cup is fixedly connected to the bottom of the foot switch, and an operation panel is installed on the surface of the frame located between the two support members.

[0012] Through the above technical solutions, some bending equipment has a dedicated support structure on the side where the worker stands, allowing the worker to place the sheet metal on it before operation or during the retraction of the upper die, without having to lift it by hand. However, some door panels are quite long, and when the worker flips them, the support structure may block the door panel, requiring the worker to move to the outside of the support structure or lift the door panel with their arm, which is cumbersome and inconvenient. In this device, when the user is bending according to the steps, if the sheet metal needs to be flipped before the next bend, they can step on the foot switch to make the electric push rod drive the support to fold up. Then, the flipping operation can be smoothly connected after the current bending operation is completed, without being blocked by the support structure or experiencing any stagnation. After the flipping is completed, the foot switch can be released to allow the support to return to its original position. The structural design is reasonable and convenient for workers to operate.

[0013] As a further embodiment of this utility model, the bending structure includes a first electric telescopic rod, a plurality of which are fixedly connected to the top of the frame, and an installation component is fixedly connected between the telescopic ends of the plurality of first electric telescopic rods, and an upper pressure mold is fixedly connected to the bottom of the installation component.

[0014] With the above technical solution, the user can insert the sheet material between the lower and upper die, and then activate the first electric telescopic rod to press the bottom of the upper die firmly into the bending groove of the lower die, thereby bending the sheet material.

[0015] As a further embodiment of this utility model, a lower die is fixedly connected to the frame surface located below the upper die, and a bending groove is provided on the top surface of the lower die, which matches the bottom of the upper die.

[0016] With the above technical solution, when the upper die moves down, the sheet material placed on the lower die will be pressed into the bending groove and then bent.

[0017] As a further embodiment of this utility model, the positioning structure includes a second electric telescopic rod, which is fixedly connected to the inner wall of the frame. A lifting platform is fixedly connected to the telescopic end of the second electric telescopic rod. A third electric telescopic rod is fixedly connected to the top of the lifting platform. A connecting piece is fixedly connected to the telescopic end of the third electric telescopic rod. Positioning blocks are fixedly connected to both ends of the connecting piece.

[0018] Through the above technical solution, in order to ensure that the bending position on the board meets the required requirements, the structure is designed with a positioning structure. The control module can drive the positioning block to move up and down through the second electric telescopic rod, and the third electric telescopic rod can drive the positioning block to move back and forth, so that the positioning block is in the set position. In this way, after the user pushes the board between the upper and lower pressing molds, its end can smoothly abut against the positioning block to complete the positioning operation.

[0019] As a further embodiment of this utility model, a control module is fixedly connected to one side wall surface of the frame, and the first electric telescopic rod, the second electric telescopic rod, the third electric telescopic rod, the electric push rod, the operation panel, the foot switch and the drive motor are all electrically connected to the control module.

[0020] Through the above technical solution, the control module in this structure can operate various electrical appliances on the equipment, thereby facilitating operation by staff.

[0021] Compared with related technologies, the bending equipment for door frame production provided by this utility model has the following advantages:

[0022] 1. In this utility model, after the user bends the sheet metal into the desired shape using the bending structure, the user can start the two drive motors on both sides through the operation panel on the frame. The drive motors can drive the lead screw to rotate, thereby causing the two sets of movable parts to move synchronously toward the user. The user can place the bent material on the first placement rack, and then take a new sheet metal from the second placement rack. Afterwards, the user can continue to start the drive motor to make the movable parts return to their original position, avoiding the position of the structure from affecting the user's flipping of the sheet metal. This structural design makes it easier and more efficient for the user to place and take materials without having to leave the frame repeatedly.

[0023] 2. In this utility model, some bending equipment has a special support structure on the side where the worker stands, so that the worker can place the sheet metal on it before operation or during the gap when the upper die retracts, without having to lift it by hand. However, some door panels are long, and when the worker flips them, the support structure will block the door panel, requiring the worker to step outside the support structure to operate, or to lift the door panel with their arm, which is cumbersome and inconvenient. In this device, when the user is bending according to the steps, if the sheet metal needs to be flipped before the next bend, they can step on the foot switch to make the electric push rod drive the support to fold up, and then the flipping operation can be smoothly connected after the current bending operation is completed. It will not be blocked by the support structure, and the movement will not be stagnant. After the flipping is completed, the foot switch can be released to let the support return to its original position. The structural design is reasonable and convenient for workers to operate.

[0031] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a bending device for door frame production according to this utility model. Figure 1 ; Figure 2 This is a schematic diagram of the overall structure of a bending device for door frame production according to this utility model. Figure 2 ; Figure 3 This is a partial structural diagram of a bending device for door frame production according to this utility model. Figure 1 ; Figure 4 This is a partial structural diagram of a bending device for door frame production according to this utility model. Figure 2 A bending device for door frame production includes:

[0032] The frame 1, the placement component 2, and the support structure 3 are provided. The frame 1 is equipped with a positioning structure 4 and a bending structure 5. The placement component 2 is provided in two sets and is located on the left and right sides of the frame 1 respectively. The placement component 2 includes two supports 25, which are distributed on the left and right sides and are rotatably connected to a lead screw 23. A drive motor 27 is fixedly connected to the surface of one support 25. The output end of the drive motor 27 is fixedly connected to one end of the lead screw 23. A movable part 26 is sleeved on the surface of the lead screw 23. The tops of the two movable parts 26 are fixedly connected to a first placement frame 14 and a second placement frame 15 respectively through support rods.

[0033] The support structure 3 includes a support member 16. There are two support members 16, both of which are hinged to the front wall surface of the frame 1. An electric push rod 17 is hinged between the support member 16 and the frame 1. A foot switch 18 is located at the front side of the frame 1 and is electrically connected to the electric push rod 17.

[0034] like Figure 1-4 As shown, positioning rods 24 are fixedly connected to the surfaces of the brackets 25 located on both the front and rear sides of the lead screw 23. The positioning rods 24 are slidably connected to the movable part 26, and the lead screw 23 is threadedly connected to the movable part 26.

[0035] In this device, after the user bends the sheet material into the desired shape using the bending structure 5, they can start the two drive motors 27 on both sides through the operation panel on the frame 1. This allows the drive motors 27 to drive the lead screw 23 to rotate, thereby causing the two sets of movable parts 26 to move synchronously toward the user. The user can place the bent material on the first placement rack 14 and then take a new sheet material from the second placement rack 15. Afterward, the user can continue to start the drive motor 27 to make the movable parts 26 return to their original positions, avoiding the structural position affecting the user's ability to flip the sheet material. This structural design allows the user to place and take materials without repeatedly leaving the frame 1, making it easier and more efficient.

[0036] like Figure 1-4 As shown, a suction cup 19 is fixedly connected to the bottom of the foot switch 18, and an operation panel is installed on the surface of the frame 1 located between the two support members 16.

[0037] Some bending equipment has a dedicated support structure 3 on the side where the worker stands, allowing the worker to place the sheet metal on it before operation or during the retraction of the upper pressing mold 21, without having to lift it by hand. However, some door panels are quite long, and the support structure 3 can block the door panel when the worker is flipping it, requiring the worker to move to the outside of the support structure 3 or lift the door panel with their arm, which is cumbersome and inconvenient. In this device, if the user needs to flip the sheet metal before the next bend while bending according to the steps, they can step on the foot switch 18 to make the electric push rod 17 drive the support member 16 to fold up. Then, the flipping operation can be smoothly connected after the current bending operation is completed, without being blocked by the support structure 3 or experiencing any stagnation. After the flipping is completed, the foot switch 18 can be released to allow the support member 16 to return to its original position. The structural design is reasonable and convenient for workers to operate.

[0038] like Figure 1-4 As shown, the bending structure 5 includes a first electric telescopic rod 7. Several first electric telescopic rods 7 are provided and are all fixedly connected to the top of the frame 1. Mounting parts 8 are fixedly connected between the telescopic ends of several first electric telescopic rods 7. An upper pressure mold 21 is fixedly connected to the bottom of the mounting parts 8.

[0039] The user can insert the sheet material between the lower die 20 and the upper die 21, and then activate the first electric telescopic rod 7 to press the bottom of the upper die 21 firmly into the bending groove 22 of the lower die 20, thereby bending the sheet material.

[0040] like Figure 1-4 As shown, a lower die 20 is fixedly connected to the surface of the frame 1 located below the upper die 21. A bending groove 22 is provided on the top surface of the lower die 20, and the bending groove 22 matches the bottom of the upper die 21.

[0041] When the upper die 21 moves down, the sheet material placed on the lower die 20 is pressed into the bending groove 22 and then bent.

[0042] like Figure 1-4 As shown, the positioning structure 4 includes a second electric telescopic rod 10, which is fixedly connected to the inner wall of the frame 1. The telescopic end of the second electric telescopic rod 10 is fixedly connected to a lifting platform 11. The top of the lifting platform 11 is fixedly connected to a third electric telescopic rod 13. The telescopic end of the third electric telescopic rod 13 is fixedly connected to a connector 9. Positioning blocks 6 are fixedly connected to both the left and right ends of the connector 9.

[0043] To ensure that the bending position on the sheet material meets the required requirements, the structure is designed with a positioning structure 4. The control module 12 enables the second electric telescopic rod 10 to move the positioning block 6 up and down, and the third electric telescopic rod 13 enables the positioning block 6 to move back and forth, thereby positioning the positioning block 6 in the set position. In this way, after the user pushes the sheet material between the upper mold 21 and the lower mold 20, its end can smoothly abut against the positioning block 6 to complete the positioning operation.

[0044] like Figure 1-4 As shown, a control module 12 is fixedly connected to one side wall surface of the frame 1. The first electric telescopic rod 7, the second electric telescopic rod 10, the third electric telescopic rod 13, the electric push rod 17, the operation panel, the foot switch 18, and the drive motor 27 are all electrically connected to the control module 12.

[0045] In this structure, the control module 12 can operate various electrical appliances on the equipment, thus facilitating operation by staff.

[0046] The working principle of the bending equipment for door frame production provided by this utility model is as follows:

[0047] First step: In this device, after the user bends the sheet material into the desired shape using the bending structure 5, the user can start the two drive motors 27 on both sides through the operation panel on the frame 1. The drive motors 27 can drive the lead screw 23 to rotate, thereby causing the two sets of movable parts 26 to move synchronously toward the user. The user can place the bent material on the first placement rack 14, and then take a new sheet material from the second placement rack 15. After that, the drive motor 27 is started again to make the movable parts 26 return to their original position, avoiding the position of the structure affecting the user's flipping of the sheet material. This structural design makes it easier and more efficient for the user to place and take materials without having to leave the frame 1 repeatedly.

[0048] The second step: Some bending equipment has a special support structure 3 on the side where the worker stands, so that the worker can place the board on it before operation or during the gap when the upper pressure mold 21 retracts, without having to lift it by hand. However, some door panels are long, and when the worker flips them, the support structure 3 will block the door panel, requiring the worker to step outside the support structure 3 to operate, or to lift the door panel with their arm, which is more troublesome and inconvenient. In this device, when the user is bending according to the steps, if the board needs to be flipped before the next bend, they can step on the foot switch 18 to make the electric push rod 17 drive the support 16 to fold up. Then, the flipping operation can be smoothly connected after the current bending operation is completed, without being blocked by the support structure 3, and the movement will not be stagnant. After the flipping is completed, the foot switch 18 can be released to let the support 16 return to its original position. The structural design is reasonable and convenient for workers to operate.
