Description

Technical Field

[0001] This utility model belongs to the technical field of bending machine equipment, and in particular relates to a material stop beam for a bending machine. Background Technology

[0002] A bending machine is a mechanical device used to bend materials to a specific angle or shape. It is widely used in construction, manufacturing, automotive, aerospace and other fields to process various metal components, such as railings, frames, pipe fittings, etc.

[0003] The operation of a rod bending machine includes the following steps: First, the rod to be bent is placed on the worktable of the bending machine and secured with clamps or clamping devices to ensure it does not move or slide during the bending process. Next, a suitable bending die is selected and installed on the bending machine according to the required bending angle and shape. Then, the drive system of the bending machine is activated, pushing the bending die to apply pressure to the rod, causing it to undergo plastic deformation under the action of the die to achieve the preset bending angle. Finally, the clamps are released, and the processed rod is removed for further processing or use. This process is efficient and precise, capable of meeting the bending needs of various metal rods.

[0004] However, existing technologies have some problems: when placing rod materials, multiple stop beams are needed to position the rods. However, when the bending machine bends the rod materials, it applies a large force, causing friction between the rods and the stop beams, which causes wear on the stop beams and affects the accuracy of the stop beams. This results in the positional accuracy of the bent part of the rod being affected. Therefore, we propose a stop beam for bending machines. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a stop beam for a bending machine. By integrating a main stop block and a transmission assembly on the worktable, the main stop block can retract during bending of the rod, reducing friction and improving durability.

[0006] This utility model is implemented as follows: a material stop beam for a bending machine includes a worktable, a stop bar, a track groove, and a sliding groove. A main stop block is slidably connected inside the sliding groove. A transmission box is provided on the worktable, and a transmission component is provided inside the transmission box. The transmission component controls the sliding adjustment of the main stop block. A clamping component is provided on the worktable, and clamping parts are provided on the clamping component.

[0007] Optionally, the transmission assembly includes a drive wheel, a connecting rod fixedly connected to the drive wheel, a bevel gear fixedly connected to the connecting rod, a driven wheel meshing with the bevel gear, the driven wheel being rotatably connected to the transmission box, a screw threadedly connected to the driven wheel, and a connecting block rotatably connected to the screw.

[0008] Optionally, the main stop block is provided with a mounting groove, which is connected to the connecting block by screws, and the mounting groove is correspondingly provided with the connecting block.

[0009] Optionally, the clamping assembly includes a mounting block, and an auxiliary stop is provided on the worktable. Both the mounting block and the auxiliary stop have limit grooves, and both the mounting block and the auxiliary stop are connected to the worktable with screws.

[0010] Optionally, the mounting block has a sliding hole, a spring is installed in the sliding hole, a guide rod is slidably connected in the sliding hole, one end of the guide rod is provided with a limit ring, the other end of the guide rod is provided with a clamping member, one end of the spring is fixedly connected to the mounting block, and the other end of the spring is in contact with the limit ring.

[0011] Optionally, the clamping member includes a fixed clamp and a movable clamp, the fixed clamp and the movable clamp are correspondingly arranged, the fixed clamp and the movable clamp are connected by screws, the fixed clamp is fixedly connected to the guide rod, and both the fixed clamp and the movable clamp are provided with arc-shaped grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting up a transmission assembly, during operation, the rod is placed on the worktable, and the cylinder drives the rack and gear to mesh. While bending the rod, the rack drives the main stop block to move in the slide groove through the transmission assembly, so that the main stop block is away from the rod. This prevents the rod from contacting the main stop block during bending, thereby reducing friction and improving the durability of the main stop block, thus ensuring the durability of the main stop block.

[0014] 2. By setting up a clamping component, when in use, pulling the clamping component causes the guide rod to retract and compress the spring. After placing the rod, releasing the clamping component allows the spring force to clamp the rod, thus fixing it in place. The movable jaws on the clamping component can be adjusted by screws to accommodate rods of different sizes. Simply pulling the clamping component allows the spring force to automatically adapt to and clamp rods of different sizes, making operation simple and quick.

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown in the figure, the present invention provides a bending machine stop beam, including a worktable 1, a stop bar 11, a track groove 12, a slide groove 13, a main stop block 2 slidably connected inside the slide groove 13, a transmission box 14, a transmission assembly 3 inside the transmission box 14, the transmission assembly 3 controlling the main stop block 2 to slide and adjust, a clamping assembly 4, and clamping parts 5 on the clamping assembly 4.

[0024] Furthermore, the present invention provides a guide beam for a bending machine, which significantly improves the bending accuracy of the rod and the durability of the guide beam. By integrating the slide groove 13 and the transmission box 14 on the worktable 1, the main stop block 2 can retract during rod bending, reducing friction and improving durability. Simultaneously, the addition of the clamping assembly 4 and its clamping parts 5 further enhances the stability of the rod during bending, improves the bending accuracy, extends the service life of the guide beam, and effectively maintains bending accuracy, thereby ensuring high precision in the bending position of the rod.

[0025] Specifically, the main stop block 2 is provided with a mounting groove 21, which is screwed to the connecting block 36. The mounting groove 21 and the connecting block 36 are correspondingly set. The transmission component 3 includes a drive wheel 31, a connecting rod 32 is fixedly connected to the drive wheel 31, a bevel gear 33 is fixedly connected to the connecting rod 32, a driven wheel 34 meshes with the bevel gear 33, the driven wheel 34 is rotatably connected to the transmission box 14, a screw 35 is internally threaded to the driven wheel 34, and a connecting block 36 is rotatably connected to the screw 35.

[0026] Furthermore, this embodiment of the invention enhances the flexibility and durability of the material-stopping beam through an innovative design that creates an mounting groove 21 on the main stop block 2 and screws it to the connecting block 36. This design makes the connection between the connecting block 36 and the main stop block 2 more stable. Simultaneously, the precise fit between the driving wheel 31, connecting rod 32, bevel gear 33, and driven wheel 34 in the transmission assembly 3, as well as the threaded connection between the screw 35 and the connecting block 36, ensures a smooth and precise transmission process, making the sliding adjustment of the main stop block 2 smoother and more accurate.

[0027] Specifically, the clamping assembly 4 includes a mounting block 41, and an auxiliary stop block 22 is provided on the worktable 1. Both the mounting block 41 and the auxiliary stop block 22 have limit grooves 23, and both the mounting block 41 and the auxiliary stop block 22 are screwed to the worktable 1.

[0028] Furthermore, by introducing the mounting block 41 and auxiliary stop 22 into the clamping assembly 4, and by creating corresponding limiting grooves 23 on the worktable 1, the stability and precision control of the rod during the bending process are further enhanced. Both the mounting block 41 and the auxiliary stop 22 are securely connected to the worktable 1 with screws, ensuring their stability during operation and effectively preventing displacement caused by vibration or external forces. Simultaneously, the design of the limiting grooves 23 makes the positioning of the rod in the clamping assembly 4 more precise, reducing bending errors caused by positional deviations. This not only improves the overall efficiency of the bending operation, but more importantly, it significantly enhances the clamping capacity and precision retention of the stop beam.

[0029] Specifically, the mounting block 41 has a sliding hole 42, a spring 43 is installed in the sliding hole 42, a guide rod 44 is slidably connected in the sliding hole 42, a limit ring 45 is provided at one end of the guide rod 44, a clamping member 5 is provided at the other end of the guide rod 44, one end of the spring 43 is fixedly connected to the mounting block 41, and the other end of the spring 43 is in contact with the limit ring 45.

[0030] Furthermore, this embodiment of the invention further enhances the clamping flexibility and adaptability of the clamping member 5 by providing a sliding hole 42 on the mounting block 41 and incorporating structures such as a spring 43, a guide rod 44, and a clamping member 5. The introduction of the spring 43 ensures that the clamping member 5 always clamps the rod, guaranteeing stable clamping of the rod. The design of the guide rod 44 and the limiting ring 45 ensures the stability and guidance of the clamping member 5 during sliding, effectively preventing damage to the rod or positioning deviation caused by uneven clamping force.

[0031] Specifically, the clamping component 5 includes a fixed clamping claw 51 and a movable clamping claw 52. The fixed clamping claw 51 and the movable clamping claw 52 are correspondingly arranged and connected by screws. The fixed clamping claw 51 is fixedly connected to the guide rod 44. Both the fixed clamping claw 51 and the movable clamping claw 52 are provided with arc-shaped grooves 53.

[0032] Furthermore, this embodiment of the invention, through the design of a clamping member 5 combining a fixed clamping claw 51 and a movable clamping claw 52, ​​further enhances the clamping effect and adaptability of the stop beam. The fixed clamping claw 51 and the movable clamping claw 52 are correspondingly arranged and connected by screws, allowing the opening and closing degree of the clamping member 5 to be flexibly adjusted according to the size of the rod, ensuring stable clamping of rods of different specifications. Simultaneously, the fixed connection between the fixed clamping claw 51 and the guide rod 44, as well as the arc-shaped groove 53 designed on both, not only enhances the stability and guiding properties of the clamping member 5 but also helps reduce damage to the rod during clamping, improving the accuracy and safety of bending operations.

[0033] Working principle: During operation, the rod is placed on the workbench 1. The cylinder drives the rack and gear to mesh. While bending the rod, the rack drives the main stop 2 to move in the slide groove 13 through the transmission component 3, so that the main stop 2 is away from the rod. This prevents the rod from contacting the main stop 2 during bending, thereby reducing friction and improving the durability of the main stop 2.

[0034] In use, pull the clamping part 5, which will cause the guide rod 44 to retract and compress the spring 43. After placing the rod, release the clamping part 5. The spring force of the spring 43 will cause the clamping part 5 to clamp the rod, thereby fixing the rod. The movable jaw 52 on the clamping part 5 can be adjusted by screws to adjust the clamping range to adapt to rods of different sizes.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
