Description

Technical Field

[0001] This application relates to the technical field of sheet metal processing equipment, and in particular to an auxiliary support frame for sheet metal for a bending machine. Background Technology

[0002] In the sheet metal processing industry, bending machines are commonly used equipment to bend sheet metal into the required shapes. When using a bending machine to bend sheet metal, due to the sheet metal's inherent length and weight, the portion of the sheet metal not held by the bending machine is prone to sagging and deforming due to gravity during the bending process. This reduces the bending accuracy and affects processing quality. Furthermore, when processing sheet metal of different sizes and shapes, it is difficult to quickly and accurately position and support the sheet metal, thus reducing processing efficiency.

[0003] A search revealed Chinese Patent Publication No. CN205628997U, which discloses a bending machine with a support frame. The machine includes a frame, a moving mold on top of the frame, a fixed mold on the lower part of the frame corresponding to the moving mold, a support frame on the frame corresponding to the fixed mold, the support frame being hinged to the frame, a support member between the support frame and the frame, an extension frame on the other side of the support frame corresponding to the frame, a sliding cavity inside the support frame, and the extension frame being slidably connected to the sliding cavity within the sliding cavity.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: existing support frames lack flexible adjustment mechanisms, resulting in time-consuming positioning of different sized plates and unstable support, thus affecting work efficiency. To address the problem of inconvenient positioning and support adjustment for different sized plates during plate bending in the prior art, this application establishes horizontal and vertical adjustment mechanisms and locking components, achieving precise support of the plates and improving bending accuracy and processing efficiency. Utility Model Content

[0005] To improve the ease of use of the support frame, this application provides an auxiliary support frame for sheet metal in a bending machine.

[0006] This application provides an auxiliary support frame for sheet metal in a bending machine, employing the following technical solution: It includes a base plate, on which a horizontal adjustment mechanism and a vertical adjustment mechanism are provided; the horizontal adjustment mechanism includes a support rod slidably connected to the base plate; a locking assembly is provided on the support rod; the locking assembly includes a locking plate fixedly mounted on the base plate; the locking plate has multiple locking blocks, the side of the locking block facing the bending machine being a first right-angled surface, and the side of the locking block facing away from the bending machine being a first inclined surface; a clamping plate is rotatably connected to the bottom of the support rod, and a limit plate is slidably connected to the lower end face of the support rod. The distance between the support frame and the bending machine is adjusted by the horizontal adjustment mechanism, thereby accommodating sheet metal of different specifications.

[0008] Optionally, a torsion spring is sleeved on the peripheral wall of the first rotating rod, with one end of the torsion spring fixedly connected to the first rotating rod and the other end of the torsion spring fixedly connected to the first rotating frame.

[0009] Optionally, the bottom of the support rod is provided with a first sliding groove, and the limiting plate is slidably connected to the support rod through the first sliding groove.

[0010] Optionally, the upper part of the limiting plate is provided with a lifting handle, and the support rod is provided with a through groove for accommodating the lifting handle; the through groove communicates with the first sliding groove; a first compression spring is provided between the top of the limiting plate and the wall of the first sliding groove.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This utility model, through the sliding connection between the support rod and the base plate in the horizontal adjustment mechanism, can change the lateral distance between the support frame and the bending machine, thereby adapting to plates of different lengths. In the vertical adjustment mechanism, rotating the first lead screw can cause the support plate to rise or fall along the second sliding groove, thus adapting to the working surface height of different specifications of bending machines and the support requirements of plates of different thicknesses.

[0016] 2. This utility model achieves unidirectional locking of the support rod through the cooperation of the locking block on the locking plate and the clamping plate. When the support rod moves towards the bending machine, it can be smoothly adjusted and stably fixed after adjustment, preventing positional changes due to factors such as the weight of the sheet metal and ensuring the stability of the support. By pulling the handle to release the limiting plate's restriction on the clamping plate, the support rod can be moved away from the bending machine. The operation is simple and can quickly complete the positioning and support adjustment of sheets of different sizes and shapes, improving processing efficiency. Attached Figure Description

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] This application discloses an auxiliary support frame for sheet metal used in a bending machine. For example... Figure 1 As shown, the system includes a base plate 1, on which a horizontal adjustment mechanism and a vertical adjustment mechanism are provided. The horizontal adjustment mechanism includes a support rod 2 slidably connected to the base plate 1. A locking assembly is provided on the support rod 2. The locking assembly includes a locking plate 3 fixedly mounted on the base plate 1. Multiple locking blocks 4 are provided on the locking plate 3. The side of the locking block 4 facing the bending machine is a first right-angled surface 5, and the side of the locking block 4 facing away from the bending machine is a first inclined surface 6. A clamping plate 7 is rotatably connected to the bottom of the support rod 2, and a limit plate 8 is slidably connected to the lower end face of the support rod 2.

[0025] In this embodiment, the distance between the support frame and the bending machine is adjusted by a horizontal mechanism to accommodate plates of different lengths, and the height of the working surface of the support frame is adjusted by a vertical adjustment mechanism to accommodate bending machines of different specifications. The locking plate 3 locks the clamping plate 7 in one direction, making it easier for the operator to adjust the lateral distance between the support rod 2 and the bending machine.

[0026] Please see Figure 2 and Figure 3 The bottom of the support rod 2 is provided with a first rotating frame 9, and the card plate 7 is provided with a first rotating rod 10; the card plate 7 is rotatably connected to the support rod 2 through the first rotating rod 10 and the first rotating frame 9; a torsion spring 11 is sleeved on the peripheral wall of the first rotating rod 10, one end of the torsion spring 11 is fixedly connected to the first rotating rod 10, and the other end of the torsion spring 11 is fixedly connected to the first rotating frame 9.

[0027] In this embodiment, when the operator pushes the support rod 2 toward the bending machine, the clamping plate 7 abuts against the first inclined surface 6 of the locking block 4. As the support rod 2 moves continuously, the clamping plate 7 rotates around the axis of the first rotating rod 10, thereby avoiding the locking block 4, and simultaneously storing energy in the torsion spring 11. When the clamping plate 7 no longer contacts the locking block 4, the torsion spring 11 drives the clamping plate 7 to reset. After the position of the support rod 2 is adjusted, the clamping plate 7 cannot rotate forward or backward under the combined action of the first right-angled surface 5 of the locking block 4 and the limiting plate 8, thereby locking the clamping plate 7 and achieving one-way locking of the support rod 2.

[0028] Please see Figure 4 The bottom of the support rod 2 is provided with a first sliding groove, and the limiting plate 8 is slidably connected to the support rod 2 through the first sliding groove; the upper part of the limiting plate 8 is provided with a lifting handle 12, and the support rod 2 is provided with a through groove 13 for accommodating the lifting handle 12; the through groove 13 communicates with the first sliding groove; a first compression spring 14 is provided between the top of the limiting plate 8 and the wall of the first sliding groove.

[0029] In this embodiment, when the position of the support rod 2 needs to be adjusted, the operator moves the pull handle 12 upward, the limiting plate 8 moves upward and releases the limiting of the clamping plate 7, the first compression spring 14 is compressed, the operator pushes the support rod 2 away from the bending machine, the clamping plate 7 contacts the first right angle surface 5 on the locking block 4, and under the obstruction of the first right angle surface 5, rotates in the direction of the bending machine with the axis of the first rotating rod 10 as the center, thereby avoiding the locking block 4 and realizing the release of the one-way locking of the support rod 2;

[0030] When the operator releases the lifting handle 12, the first compression spring 14 drives the limit plate 8 to move downward and reset.

[0031] Please see Figure 4 The support rod 2 has a second sliding groove 15, and the support plate 16 is slidably connected to the second sliding groove 15; the first lead screw 17 is rotatably connected inside the second sliding groove 15, and the lead screw nut that matches the first lead screw 17 is fixedly installed on the support plate 16.

[0032] In this embodiment, rotating the first lead screw 17 causes the support plate 16 to rise or fall along the second sliding groove 15, thereby adapting to different bending machine heights.

[0033] Please see Figure 1 A sliding frame 18 is fixedly installed on the base plate 1, and a first sliding rod 19 is installed on the sliding frame 18; a first sliding hole adapted to the first sliding rod 19 is opened on the support rod 2;

[0034] In this embodiment, the first sliding rod 19 and the sliding frame 18 make the support and movement of the support rod 2 more stable.

[0035] The implementation principle of the sheet metal auxiliary support frame for a bending machine in this application embodiment is as follows:

[0036] The base plate 1 is fixedly installed in a suitable position next to the bending machine to ensure that the sliding frame 18 and the first sliding rod 19 are stably connected, providing guidance for the horizontal movement of the support rod 2. The operator pushes the support rod 2 towards the bending machine, at which time the clamping plate 7 contacts the first inclined surface 6 of the locking block 4. Under the blocking action of the inclined surface, the clamping plate 7 rotates around the axis of the first rotating rod 10, compressing the torsion spring 11 to store energy, avoiding the locking block 4, and the support rod 2 can move smoothly. When the clamping plate 7 passes the locking block 4, the torsion spring 11 resets and drives the clamping plate 7 to fit against the first right-angled surface 5 of the locking block 4. At the same time, the limiting plate 8 limits the clamping plate 7 to prevent the clamping plate 7 from rotating in the other direction around the axis of the first rotating rod 10, thus forming a one-way locking (the support rod 2 can only move towards the bending machine and cannot be reversed).

[0037] When it is necessary to move away from the bending machine, the operator pulls the lifting handle 12 upwards, causing the limiting plate 8 to move upwards along the first sliding groove, compressing the first compression spring 14, and releasing the limiting plate 8 from limiting the clamping plate 7; pushing the support rod 2 away from the bending machine, the clamping plate 7 contacts the first right-angled surface 5 of the locking block 4, and under the action of resistance, rotates around the first rotating rod 10 towards the bending machine, disengaging from the locking block 4, thus unlocking; releasing the lifting handle 12, the first compression spring 14 drives the limiting plate 8 to reset, and limits the clamping plate 7 again;

[0038] By manually or with tools, the first lead screw 17 in the second sliding groove 15 is rotated, and the lead screw nut drives the support plate 16 to move up and down along the second sliding groove 15. After the lead screw is stopped, the support plate 16 is fixed at the target height through the threaded engagement between the lead screw nut and the first lead screw 17, which can adapt to the working surface height of different specifications of bending machines.

[0039] Place one end of the sheet material to be bent on the clamping end of the bending machine, and the other end on the support plate 16. Adjust the horizontal and vertical positions so that the support plate 16 supports the unclamped part of the sheet material. When the bending machine applies force to the bending part, the support plate 16 provides stable support through the support rod 2 and the locking assembly, preventing the sheet material from sagging due to gravity and ensuring bending accuracy. If the sheet material is changed to a different length or thickness, repeat the horizontal and vertical adjustment steps to quickly locate the support point.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
