Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate profile processing, in particular to a punching device based on aluminum plate profile. Background Art

[0002] In the field of aluminum sheet profile processing, the stamping device is the key equipment to achieve profile forming. The existing stamping device for aluminum sheet profiles is usually equipped with a basic limit and clamping mechanism. Its core structure includes a mounting plate, a roller and a simple driving component. The mounting plate is used to carry the aluminum sheet profile to be processed (i.e., the workpiece), and the roller applies pressure to the aluminum sheet through relative movement in the up and down or horizontal direction, so that it undergoes plastic deformation to achieve a predetermined shape. The driving component generally uses a motor or a hydraulic cylinder, which is responsible for controlling the spacing and pressure of the rollers and the feed speed of the workpiece; However, there are the following technical defects in the stamping process of aluminum profiles: Insufficient limiting accuracy, which can easily lead to rolling deviation: Existing devices mostly use fixed baffles or low-precision limiting wheels, which cannot dynamically adapt to the thermal expansion, vibration or slight deformation of the workpiece during the rolling process. This rigid limiting method can easily cause interference between the workpiece and the limiting structure, resulting in deviation or tilt during rolling, and then causing defects such as edge wrinkles and uneven thickness; Uneven rolling at the ends affects product quality: the existing equipment is not capable of handling the ends of the workpiece, especially when the length of the workpiece exceeds the effective contact range of the rollers. The ends are prone to insufficient rolling or uneven deformation due to insufficient force. This local defect will directly affect the mechanical properties and appearance quality of the profile and reduce the yield rate. Summary of the invention

This series of actions optimizes the rolling process and ensures the smooth progress of rolling. BRIEF DESCRIPTION OF THE DRAWINGS

The moving member 410 includes a slide bar 411, a tooth plate 412 and a top plate 413. The ends of the slide bar 411 and the tooth plate 412 are fixedly connected. The top plate 413 is fixedly installed on the top of the slide bar 411 and the tooth plate 412. The slide bar 411 and the tooth plate 412 are slidably installed on the mounting seats 49, and the tooth plate 412 is meshed with the half gear 48. Support rods 415 are slidably connected to both sides of the mounting plate 414 in a transverse manner. The support rods 415 are L-shaped, and one end of the support rods 415 is fixedly mounted on the fixing plate 41, and a row of pulleys 416 for assisting the movement of the workpiece 3 is arranged on the top of the other end. A second cylinder 419 is fixedly installed on both sides of the top of the mounting plate 414, and a U-shaped plate 418 is fixedly connected to the output end of the second cylinder 419, and the U-shaped plate 418 is slidably installed on the T-shaped plate 417, and a moving rod 424 is slidably connected to both sides of the T-shaped plate 417, and a pressing block 420 that is slidably adapted to the U-shaped plate 418 is fixedly connected to the bottom of the moving rod 424, and a damping spring 425 sleeved on the moving rod 424 is provided between the pressing block 420 and the T-shaped plate 417, and limiting wheels 421 rotatably installed on the mounting plate 414 are provided on both sides of the pressing block 420; The U-shaped plate 418 includes a lifting rod 422 and a pushing rod 423, the lifting rod 422 and the pushing rod 423 are fixedly connected, the end of the lifting rod 422 is tilted and corresponds to the position of the pressing block 420, and the end of the pushing rod 423 corresponds to the position of the working piece 3.

[0020] In the embodiment of the present invention, during the rolling process of the workpiece 3, the workpiece 3 needs to be placed between the two control components 4, and at the same time, ensure that the workpiece 3 is also located between the two rollers 2. Specifically, both ends of the workpiece 3 need to be placed on the mounting plate 414 to ensure its stability. In order to further support the bottom of the workpiece 3, the support rod 415 and the pulley 416 are designed to provide necessary support. The function of the pulley 416 is to assist the workpiece 3 to move back and forth, so that it is more flexible during the rolling process. At the same time, the limiting wheels 421 on both sides of the mounting plate 414 limit the two sides of the workpiece 3 to prevent it from shifting. Through the limiting function of the limiting wheels 421, it can be ensured that the workpiece 3 maintains a stable position and posture during the rolling process, thereby reducing rolling defects caused by vibration or unstable factors. In addition, the pressing block 420 moves downward under the elastic force of the damping spring 425, so that the pressing block 420 cooperates with the mounting plate 414 to clamp and fix the end of the workpiece 3. The pressing block 420 moves downward under the elastic force of the damping spring 425 and is in close contact with the end of the workpiece 3 to form a clamping fixation. This clamping method can effectively fix the workpiece 3 to prevent it from moving or slipping during the rolling process. Next, the servo motor 43 is turned on to drive the transmission rod 42 to rotate synchronously, and the transmission rod 42 drives another transmission rod 42 to rotate synchronously through the synchronous pulley transmission member 44, so that the transmission rod 42 drives the driving gear 45 to rotate synchronously, and the driving gear 45 drives the two meshing driven gears 47 to rotate synchronously, and the driven gear 47 drives the half gear 48 to rotate synchronously, so that the two half gears 48 can intermittently drive the meshing toothed plate 412 and the sliding rod 411, the top plate 413, the mounting plate 414, and the T-plate 417 on the mounting seat 49 to reciprocate during the continuous rotation process, thereby driving the working piece 3 located between the two control components 4 to be located The two rollers 2 reciprocate and use the rollers 2 to reciprocate the workpiece 3. The control component 4 controls the workpiece 3 to reciprocate on the rollers 2, thereby improving the stability of the rollers 2 when rolling the workpiece 3, so that it can continue to perform cold rolling work stably. In this process, the control components 4 on both sides cooperate with each other to control the workpiece 3 to move on the upper and lower rollers 2. The control component 4 controls the reciprocating movement of the workpiece 3 between the rollers 2, which reduces the rolling deviation caused by unstable position, thereby improving the rolling accuracy and stability. The stable rolling process reduces the wear and impact of the rollers 2, thereby extending the service life of the rollers; The reciprocating rolling method enables the workpiece 3 to pass through the roller 2 multiple times, thereby receiving more rolling times in the same time, thereby improving the cold rolling efficiency. When one end of the workpiece 3 moves to the vicinity of the roller 2, in order to prevent the end from being unable to be rolled, the second cylinder 419 is turned on to drive the U-shaped plate 418 and the end of the workpiece 3 to move toward the side of the roller 2. In this way, the lifting rod 422 on the U-shaped plate 418 pushes the pressing block 420 and the moving rod 424 upward through the inclined surface and compresses the damping spring 425, so that the pressing block 420 no longer suppresses the end of the workpiece 3. At the same time, the pushing rod 423 pushes the end of the workpiece 3 to move onto the upper and lower rollers 2. The roller 2 is enabled to roll the end of the workpiece 3. At the same time, when the two control components 4 control the workpiece 3 to move in the opposite direction, the other end of the workpiece 3 can be rolled. Through the push of the second cylinder 419, the U-shaped plate 418 and the end of the workpiece 3 can move toward the side of the roller 2, ensuring that the entire workpiece can be rolled evenly and completely. During the rolling process, both side ends of the workpiece 3 can be rolled, which helps to improve the overall uniformity of the rolled product. Through the coordinated work of the two control components 4, when the workpiece 3 moves back and forth between the rollers 2, both side ends of the workpiece 3 can be fully rolled, reducing quality problems caused by uneven rolling.

[0021] Embodiment 2: Combination Figure 2 , Figure 3 , Figure 4 As shown, on the basis of the first embodiment, the roll 2 includes a support roll 21 and a working roll 22, the support roll 21 and the working roll 22 are rotatably mounted on the support frame 1 through a mounting frame 23, and the support roll 21 is located at the outer end of the working roll 22, during the working process of the working roll 22, the support roll 21 is tightly attached to the working roll 22 to prevent deformation, and during the rotation of the working roll 22, the support roll 21 will also rotate, and will not hinder the work of the working roll 22; A first positioning seat 26 and a second positioning seat 28 are respectively provided on both sides of the support frame 1, and a first adjusting rod 27 and a second adjusting rod 29 are respectively threadedly connected to the first positioning seat 26 and the second positioning seat 28, a support base 24 is provided at the inner end of the first adjusting rod 27, and the mounting frame 23 is fixedly installed on the support base 24, an adjusting base 25 is provided at the inner end of the second adjusting rod 29, and the support base 24 is slidably installed on the adjusting base 25, the bottom of the support base 24 and the top of the adjusting base 25 are both inclined and slidably arranged, and the first positioning seat 26 and the second positioning seat 28 can be installed, positioned and fixed according to actual requirements; A frame 211 is fixedly installed on the upper end of the support frame 1, and a first cylinder 212 is fixedly installed on the frame 211.

The fixing seat 210 is connected to the roller 2 located above.

[0022] In the embodiment of the present invention, by controlling the first adjusting rod 27 and the second adjusting rod 29 to move inward, the first adjusting rod 27 and the second adjusting rod 29 drive the support base 24 and the adjusting base 25 to move inward. When the support base 24 and the adjusting base 25 move inward, since the bottom of the support base 24 and the top of the adjusting base 25 are both inclined and slidably arranged, the support base 24 and the adjusting base 25 drive the roller 2 located below to move upward when moving inward, thereby adjusting the position of the roller 2 below. By turning on the first cylinder 212, the connecting rod 213 and the fixing seat 210 are driven to move downward, thereby driving the roller 2 located above to move downward, thereby adjusting the position of the upper roller 2; By adjusting the gap between the upper and lower rollers 2, the thickness of the workpiece during the rolling process can be accurately controlled, which is crucial for producing products with specific thickness specifications. The appropriate rolling gap can ensure the uniformity and consistency of product thickness. Accurate adjustment of the position of roller 2 helps reduce defects in the rolling process, such as uneven thickness, surface scratches, cracks, etc. These defects will directly affect the appearance and performance of the product, and the appropriate position of roller 2 can minimize the occurrence of these problems, thereby improving product quality.
