Technical Field

[0001] This utility model relates to the field of trucks that are easy to load and unload, and more specifically, to a high-precision bending machine lower die guide rail structure. Background Technology

[0002] In the field of sheet metal bending, the lower die guide structure is the core component that determines bending accuracy and efficiency.

[0003] Traditional bending machines typically use a fixed V-groove design for the lower die, which has a single and non-adjustable groove size. When processing plates of different thicknesses or angles, the machine must be stopped, the entire lower die disassembled, and the corresponding V-groove module replaced. This operation is cumbersome and time-consuming. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a high-precision bending machine lower die guide rail structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows: A high-precision bending machine lower die guide rail structure includes a lower die guide rail mounting block, a lower die V-groove replacement component is provided inside the lower die guide rail mounting block, a clamping drive component is provided on one side of the lower die V-groove replacement component, and a bending buffer component is provided at the bottom of the lower die guide rail mounting block. To achieve this, the lower mold V-groove replacement component includes a replacement mounting slot, which is located inside the lower mold guide rail mounting block. The replacement mounting slot contains multiple V-modules. The lower mold guide rail mounting block has symmetrical sliding clamping slots on both sides. Clamping rods are slidably fitted inside the sliding clamping slots. Clamping plates are connected to the periphery of the clamping rods. Transmission threaded sleeves are symmetrically connected to one side of each of the two clamping plates. Transmission threaded rods are threadedly fitted inside the transmission threaded sleeves.

[0006] Furthermore, the transmission threaded rod is formed by symmetrically welding two threaded rods.

[0007] Furthermore, a sliding connecting plate is connected to the bottom of the lower mold guide rail mounting block. The sliding connecting plate is symmetrically installed at the bottom of the lower mold guide rail mounting block. A sliding limit rod is connected to the periphery of the sliding connecting plate, and the sliding limit rod slides in cooperation with the clamping plate.

[0008] Furthermore, the clamping drive assembly includes a transmission worm gear, a transmission worm meshing around the transmission worm gear, a worm fixing plate movably connected around the transmission worm, the worm fixing plate being connected to the lower mold guide rail mounting block, a drive motor connected to one end of the transmission worm, and the drive motor housing being connected to the worm fixing plate.

[0009] Furthermore, a controller is installed on one side of the lower mold guide rail mounting block, and the drive motor is electrically connected to the controller.

[0010] Furthermore, the bending buffer assembly includes a bending buffer mounting bracket, which is connected to the lower die guide rail mounting block. A damper is connected below the bending buffer mounting bracket, a return spring is sleeved around the damper, and a sliding seat is connected to the bottom of the damper.

[0011] Furthermore, the sliding seat and the bending buffer mounting bracket are in sliding engagement.

[0012] The beneficial effects of this utility model are as follows: (1) This utility model has made improvements to the existing technology. In actual use, by replacing the lower die V groove component, the traditional bending machine lower die usually adopts a fixed V groove design, and its groove size is single and cannot be adjusted.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] According to an embodiment of the present invention, a high-precision bending machine lower die guide rail structure is provided, including a lower die guide rail mounting block 1, a lower die V-groove replacement component 2 is provided inside the lower die V-groove replacement component 1, a clamping drive component 3 is provided on one side of the lower die V-groove replacement component 2, and a bending buffer component 4 is provided at the bottom of the lower die guide rail mounting block 1.

[0019] like Figure 1-4 As shown, according to the high-precision bending machine lower die guide rail structure of this utility model embodiment, the lower die V-groove replacement component 2 includes a replacement mounting groove 201, which is opened inside the lower die guide rail mounting block 1. The replacement mounting groove 201 is provided with a multi-V module 202. The lower die guide rail mounting block 1 is symmetrically provided with sliding clamping grooves 203 on both sides. The sliding clamping grooves 203 are slidably fitted with clamping rods 204. The clamping rods 204 are connected to clamping plates 205 on their periphery. The two clamping plates 205 are symmetrically connected to one side of each of the two clamping plates 205. The transmission threaded sleeves 206 are threadedly fitted with transmission threaded rods 207 inside the transmission threaded sleeves 206. The transmission threaded rods 207 are symmetrically welded by two screws. The lower die guide rail mounting block 1 is connected to a sliding connecting plate 5. The sliding connecting plate 5 is symmetrically installed at the bottom of the lower die guide rail mounting block 1. The sliding connecting plate 5 is connected to a sliding limiting rod 6 on its periphery. The sliding limiting rod 6 is slidably fitted with the clamping plate 205.

[0020] Through the above technical solution, the core function of the high-precision bending machine lower die guide rail structure during operation is to facilitate the convenient replacement and stable clamping of the lower die multi-V module 202, and to absorb bending impact. When different V-grooves need to be replaced to adapt to different bending requirements, the operator places the selected multi-V module 202 into the replacement mounting slot 201 inside the lower die guide rail mounting block 1. At this time, the controller 7 issues a command to start the drive motor 304 in the clamping drive assembly 3. The drive motor 304 drives the transmission worm gear 302 to rotate, and the transmission worm gear 302 drives the transmission worm wheel 301 meshing with it to rotate. The rotation of the transmission worm wheel 301 directly drives the two symmetrically welded transmission threaded rods 207 to rotate synchronously.

[0021] like Figure 1-4 As shown, according to the high-precision bending machine lower die guide rail structure of this utility model embodiment, the clamping drive assembly 3 includes a transmission worm gear 301, a transmission worm 302 meshing around the transmission worm gear 301, a worm fixing plate 303 movably connected around the transmission worm 302, the worm fixing plate 303 being connected to the lower die guide rail mounting block 1, a drive motor 304 connected to one end of the transmission worm 302, the housing of the drive motor 304 being connected to the worm fixing plate 303, a controller 7 being installed on one side of the lower die guide rail mounting block 1, and the drive motor 304 being electrically connected to the controller 7.

[0022] Through the above technical solution, the rotating transmission threaded rod 207 drives the two transmission threaded sleeves 206 to move towards or away from each other along the axial direction of the transmission threaded rod 207 through threaded engagement with the transmission threaded sleeves 206. Since the transmission threaded sleeves 206 are fixedly connected to the clamping plate 205, the clamping plate 205 moves synchronously. The clamping plate 205 drives the clamping rod 204 fixed thereon to slide within the sliding clamping grooves 203 symmetrically opened on both sides of the lower mold guide rail mounting block 1. In order to ensure the straightness and stability of the movement of the clamping plate 205, the clamping plate 205 also slides in engagement with the sliding limit rod 6 on the periphery of the sliding connecting plate 5 fixed at the bottom of the lower mold guide rail mounting block 1. When the two clamping plates 205 move toward each other under the drive, the clamping rods 204 on them firmly clamp the multi-V module 202 located in the replacement mounting slot 201 from both sides, locking it in the working position; the reverse movement releases the multi-V module 202 for replacement. The entire drive and clamping process is supported by the worm gear fixing plate 303.

[0023] like Figure 1-4As shown, according to the high-precision bending machine lower die guide rail structure of this utility model embodiment, the bending buffer assembly 4 includes a bending buffer mounting bracket 401, which is connected to the lower die guide rail mounting block 1. A damper 402 is connected below the bending buffer mounting bracket 401, and a return spring 403 is sleeved around the damper 402. A sliding seat 404 is connected to the bottom of the damper 402, and the sliding seat 404 slides in cooperation with the bending buffer mounting bracket 401.

[0024] Through the above technical solution, when the bending machine is performing sheet metal bending operations, the upper die applies pressure to the sheet metal, which presses against the multi-V module 202 of the lower die, thereby transmitting the impact force to the entire lower die structure. To effectively absorb and buffer this impact force, improving bending accuracy and component lifespan, the bending buffer assembly 4 located at the bottom of the lower die guide rail mounting block 1 plays a role. The impact force is transmitted through the bending buffer mounting bracket 401 to the damper 402 and the return spring 403 sleeved around the damper 402. Under pressure, the sliding seat 404 slides downward relative to the bending buffer mounting bracket 401, and the two slide in cooperation, compressing the return spring 403 and forcing the damper 402 to produce a damping effect, converting the impact kinetic energy into heat energy for dissipation. When the bending pressure is removed, the compressed return spring 403 pushes the sliding seat 404, along with the entire buffer device, upward to reset the lower die structure to its initial position, preparing for the next bending operation.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
