Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, specifically to a sheet metal flattening device for sheet metal processing. Background Technology

[0002] In the field of sheet metal processing, flattening sheet metal parts is a crucial step. During the manufacturing process, sheet metal parts often experience deformation, warping, or unevenness due to processes such as stamping, cutting, and welding. These uneven sheet metal parts not only affect the appearance quality of the product but also cause a series of problems during subsequent assembly, use, and maintenance, such as excessive assembly gaps, poor sealing performance, and stress concentration leading to cracking. Traditional sheet metal flattening methods mainly rely on manual operation, using manual hammering or simple mechanical devices to correct the sheet metal parts. However, this method has many shortcomings. First, manual operation is inefficient and cannot meet the needs of large-scale production; second, manual hammering makes it difficult to precisely control the force and direction, easily leading to excessive deformation or surface damage of the sheet metal parts; third, simple mechanical devices often lack flexibility and adaptability, and cannot handle sheet metal parts of different shapes and sizes.

[0003] With the advancement of technology and the development of automation, more and more companies are exploring the use of automated sheet metal flattening devices to improve production efficiency and product quality. However, existing automated flattening devices also have some problems. For example, during the flattening process of sheet metal parts, the lack of a stable structure to fix the sheet metal parts can lead to accidental displacement, thus affecting the flattening effect. Therefore, it is necessary to provide a sheet metal flattening device for sheet metal processing to solve the above-mentioned technical problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To overcome the shortcomings of existing technologies, a sheet metal flattening device for sheet metal processing is proposed to solve the problem that when flattening sheet metal parts, the lack of a stable structure to fix the sheet metal parts leads to accidental displacement of the sheet metal parts during the flattening process, which in turn affects the flattening effect.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a sheet metal flattening device for sheet metal processing, including a processing table, a mounting plate fixedly connected to the lower part of the processing table, and two sets of mutually symmetrical limiting components provided on the upper part of the processing table. The limiting components include a sliding plate slidably installed on the processing table, a rod sleeve fixed to the upper end of the sliding plate, and a rod body slidably inserted into the inner side of the rod sleeve. A limiting clamping rod is fixed to the other end of the rod body, and a spring is connected between the limiting clamping rod and the rod sleeve. The spring is sleeved on the outside of the rod body.

[0008] Furthermore, a drive assembly is provided at the lower part of the processing table. The drive assembly includes a stepper motor fixedly mounted on the upper part of the mounting plate, and a transmission shaft is connected to the upper power output end of the stepper motor. A first bevel gear is welded on the transmission shaft.

[0009] Furthermore, double-headed shafts are rotatably mounted on both sides of the lower part of the processing table, and a screw is fixed to one end of the double-headed shaft, while a second bevel gear that meshes with the first bevel gear is fixed to the other end of the screw. The screw is threadedly connected to the slide plate.

[0010] Furthermore, the processing table is provided with a sliding groove, and the sliding plate passes through the sliding groove and slides horizontally along its inner groove.

[0011] Furthermore, a mounting frame is fixed to the upper end of the processing table, and a hydraulic press is fixedly mounted on the top of the mounting frame. A pressure plate is fixed to the end of the hydraulic rod at the lower end of the hydraulic press.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model has the following advantages: By designing a limiting component and a driving component, specifically, by starting a stepper motor, its power output end drives the first bevel gear to rotate via a transmission shaft. The first bevel gear meshes with the second bevel gear, thereby driving the double-headed shaft to rotate. Screws are fixed to both ends of the double-headed shaft, and the screws are threadedly connected to the sliding plate. As the screws rotate, the sliding plate slides horizontally within the groove, further adjusting the position of the limiting clamp, so that the limiting clamp approaches and slightly clamps the two sides of the sheet metal part, fixing and limiting the centered sheet metal part. Due to the elastic force of the spring, the limiting clamp can adaptively adjust according to sheet metal parts of different sizes, ensuring stable clamping without damaging the surface of the sheet metal part. When the limiting component is adjusted to the correct position, the hydraulic press is started, and its hydraulic rod drives the pressure plate to descend. The pressure plate contacts and applies pressure to the sheet metal part, using the powerful pressure provided by the hydraulic press to flatten the sheet metal part. During the flattening process, the limiting component ensures that the sheet metal part will not move or deform due to excessive pressure, guaranteeing the accuracy and stability of the flattening effect.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] A sheet metal flattening device for sheet metal processing includes a processing table 1, a mounting plate 2 fixedly connected to the lower part of the processing table 1, and two sets of mutually symmetrical limiting components 3 provided on the upper end of the processing table 1. The limiting components 3 include a sliding plate 31 slidably installed on the processing table 1, a rod sleeve 32 fixed to the upper end of the sliding plate 31, and a rod body 33 slidably inserted into the inner side of the rod sleeve 32. A limiting clamping rod 34 is fixed to the other end of the rod body 33, and a spring 35 is connected between the limiting clamping rod 34 and the rod sleeve 32. The spring 35 is sleeved on the outside of the rod body 33.

[0020] In this embodiment, the limiting clamping rod 34 approaches and clamps the two sides of the sheet metal part to fix and limit the centered sheet metal part. Due to the elastic force of the spring 35, the limiting clamping rod 34 can adaptively adjust according to the sheet metal parts of different sizes to ensure stable clamping and not damage the surface of the sheet metal part.

[0021] In this embodiment, a drive assembly 4 is provided at the lower part of the processing table 1. The drive assembly 4 includes a stepper motor 41 fixedly installed on the upper end of the mounting plate 2, and a transmission shaft 42 is connected to the upper power output end of the stepper motor 41. A first bevel gear 43 is welded on the transmission shaft 42. Double-headed shafts 44 are rotatably installed on both sides of the lower part of the processing table 1. A screw 45 is fixed at one end of the double-headed shaft 44, and a second bevel gear 46 that meshes with the first bevel gear 43 is fixed at the other end of the screw 45. The screw 45 is threadedly connected to the slide plate 31. By starting the stepper motor 41, its power output end drives the first bevel gear 43 to rotate through the transmission shaft 42. The first bevel gear 43 meshes with the second bevel gear 46, thereby driving the double-headed shaft 44 to rotate. Screws 45 are fixed at both ends of the double-headed shaft 44. The screws 45 are threadedly connected to the slide plate 31. As the screws 45 rotate, the slide plate 31 slides horizontally in the slide groove 5, further adjusting the position of the limiting clamp 34.

[0022] In this embodiment, the processing table 1 is provided with a sliding groove 5, and the sliding plate 31 passes through the sliding groove 5 and slides horizontally along its inner groove.

[0023] In this embodiment, a mounting frame 6 is fixed to the upper end of the processing table 1, and a hydraulic press 7 is fixedly installed on the top of the mounting frame 6. A pressure plate 8 is fixed to the end of the hydraulic rod at the lower end of the hydraulic press 7. By starting the hydraulic press 7, its hydraulic rod drives the pressure plate 8 to descend. The pressure plate 8 contacts and applies pressure to the sheet metal part. The powerful pressure provided by the hydraulic press 7 flattens the sheet metal part. During the flattening process, the limiting component 3 ensures that the sheet metal part will not move or deform due to excessive pressure.

[0024] Working principle: When in use, the operator first places the sheet metal part on the processing table 1. By starting the stepper motor 41, its power output end drives the first bevel gear 43 to rotate through the transmission shaft 42. The first bevel gear 43 meshes with the second bevel gear 46, thereby driving the double-headed shaft 44 to rotate. The two ends of the double-headed shaft 44 are respectively fixed with screws 45. The screws 45 are threadedly connected to the slide plate 31. As the screws 45 rotate, the slide plate 31 slides horizontally in the slide groove 5, further adjusting the position of the limiting clamp 34 so that the limiting clamp 34 approaches and slightly clamps the two sides of the sheet metal part, fixing and limiting the centered sheet metal part. Due to the elastic force of the spring 35, the limiting clamp 34 can adaptively adjust according to the sheet metal parts of different sizes, ensuring stable clamping and not damaging the surface of the sheet metal part.

[0025] Once the limiting component 3 is adjusted to the correct position, the hydraulic press 7 starts, and its hydraulic rod drives the pressure plate 8 to descend. The pressure plate 8 contacts and applies pressure to the sheet metal part, using the strong pressure provided by the hydraulic press 7 to flatten the sheet metal part. During the flattening process, the limiting component 3 ensures that the sheet metal part will not move or deform due to excessive pressure, ensuring the accuracy and stability of the flattening effect. After the flattening operation is completed, the hydraulic rod of the hydraulic press 7 rises, the pressure plate 8 leaves the sheet metal part, the stepper motor 41 reverses, and the drive component 4 drives the slide plate 31 to reset to the initial position. The operator can then easily remove the flattened sheet metal part and prepare for the next round of processing.
