Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, specifically a sheet metal bending positioning fixture. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching, cutting, compounding, bending, welding, riveting, splicing, and forming. Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as a term when assembling parts.

[0003] Current sheet metal bending equipment requires manual adjustment and fixation of the sheet metal during operation, which is not only time-consuming and labor-intensive, but also prone to inaccurate positioning. As a result, the precision of the processed sheet metal parts does not meet the process requirements, leading to low processing efficiency. Utility Model Content

[0014] 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.

[0015] like Figure 1-5 As shown, this utility model provides a technical solution: a sheet metal bending and positioning fixture, including a workbench 1, a support foot 101 fixedly installed at the bottom of the workbench 1, a spiral device 102 provided at the center of the top of the workbench 1, a mounting groove 103 provided at the front end of the spiral device 102, a motor 104 fixedly installed inside the mounting groove 103, a threaded rod 105 fixedly connected to the rear output shaft of the motor 104, a movable block 2 connected to the outside of the threaded rod 105, a threaded hole 201 opened at the center of the front end of the movable block 2, a mounting platform 202 provided at the top of the movable block 202, a limit plate 203 provided at the top of the mounting platform 202, a through hole 204 opened at the center of the top of the mounting platform 202, a mounting hole 205 opened at the bottom of the through hole 204, a motor 206 fixedly installed inside the mounting hole 205, a placement plate 3 fixedly connected to the top of the motor 206, and a bottom of the placement plate 3... The workbench 1 has a second limiting hole 301, a connecting hole 302 at the bottom center of the placement plate 3, a hydraulic cylinder 303 fixedly installed at the top of the placement plate 3, a hydraulic rod 304 installed inside the hydraulic cylinder 303, a clamping plate 305 fixedly installed at the end of the hydraulic rod 304 away from the hydraulic cylinder 303, a second mounting groove 306 at the top center of the placement plate 3, a lower mold 307 fixedly installed inside the second mounting groove 306, a support plate 106 fixedly installed at the top rear end of the workbench 1, a mounting plate 107 set at the top of the support plate 106, a first limiting hole 108 at the top of the mounting plate 107, a cylinder 4 fixedly installed at the top center of the mounting plate 107, a telescopic rod 401 installed inside the cylinder 4, a connecting plate 402 fixedly installed at the bottom of the telescopic rod 401, a limiting rod 403 set at the top of the connecting plate 402, and an upper mold 404 fixedly connected to the bottom of the connecting plate 402.

[0016] Furthermore, the threaded rod 105 has an external thread on its outer side and an internal thread on its inner side, and the threaded rod 105 is installed inside the threaded hole 201.

[0017] The above technical solution ensures that the threaded rod 105 and the threaded hole 201 are threadedly connected, and when the threaded rod 105 rotates, the movable block 2 will move back and forth with the rotation of the threaded rod 105.

[0018] Furthermore, both the limiting hole 108 and the limiting rod 403 are symmetrical front and back, and the limiting rod 403 is installed inside the limiting hole 108.

[0019] The above technical solution limits the telescopic rod 401 to prevent misalignment during its up-and-down movement, which would lead to inaccurate bending accuracy.

[0020] Furthermore, both the limiting plate 203 and the limiting hole 301 are annular structures, and the limiting plate 203 is installed inside the limiting hole 301.

[0021] The above technical solution limits the placement plate 3 to ensure that it does not deviate from its original position during rotation.

[0022] Furthermore, the output shaft of motor 206 is installed inside the through hole 204 and the connecting hole 302.

[0023] Through the above technical solution, it is ensured that after the second motor 206 is started, it can drive the placement plate 3 to rotate through the output shaft, thereby adjusting the angle of the sheet metal parts and bending the sheet metal parts in different directions.

[0024] Furthermore, a rubber protective pad is provided at the end of the clamping plate 305 that contacts the sheet metal part.

[0025] The above technical solution utilizes the soft properties of rubber material to prevent the clamping plate 305 from damaging the sheet metal parts during the fixing process.

[0026] Working principle: First, the sheet metal part is placed on top of the placement plate 3. Then, the hydraulic cylinders 303 at the top left and right ends of the placement plate 3 are activated, causing the hydraulic rods 304 to move the clamping plate 305 towards the center to fix the sheet metal part. Then, the motor 104 is activated, causing the threaded rod 105 to rotate, causing the movable block 2 to move the placement plate 3 and the sheet metal part backward to below the upper mold 404. Then, the cylinder 4 is activated, causing the telescopic rod 401 to move the upper mold 404 downward, so that the upper mold 404 and the lower mold 307 cooperate to bend the sheet metal part. When it is necessary to bend the sheet metal part in other directions, the motor 206 can be activated to rotate the placement plate 3, so that the other directions of the sheet metal part are aligned with the upper mold 404. Finally, after the sheet metal part is bent, the motor 104 is activated to move the movable block 2 forward, so that the placement plate 3 is in front of the worker, allowing the worker to take away the sheet metal part.

[0027] 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.
