Description

These problems not only affect the aesthetics of the product, but may also reduce the performance and service life of the product. Therefore, profile straightening technology is crucial to ensure product quality, improve production efficiency, and reduce costs. The commonly used straightening method is to use mechanical stretching force at both ends of the profile to eliminate deflection and bending in the profile.

The shape and size of the protective cover 324 should match the rotating disk 323 to ensure that it can tightly wrap the rotating disk 323 without affecting the rotation of the rotating disk 323. The protective cover 324 is provided with two clamping ports 3241. The two clamping ports 3241 are respectively arranged corresponding to the two clamping devices 33.

When the clamping mechanism 332 needs to be moved, the first cylinder 3311 is started, and its movable end begins to extend and retract, and the movable member 3312 reciprocates as the movable end extends and retracts.

In this embodiment, a receiving groove is provided on the material transport plate 533 for clamping the profile. The lifting mechanism 531 includes a positioning frame 5311, a lifting cylinder 5312, a guide rail 5313 and a lifting plate 5314. The positioning frame 5311 is fixedly connected to the first transmission mechanism 521, the lifting cylinder 5312 and the guide rail 5313 are fixedly connected to the positioning frame 5311 respectively, and the lifting plate 5314 is fixedly connected to the movable end of the lifting cylinder 5312. The lifting or lowering action is generated by the telescopic movement of the piston. The lifting plate 5314 is slidably connected to the guide rail 5313, and the guide rail 5313 provides a guiding and supporting function for the lifting plate 5314 to ensure that the lifting plate 5314 can move smoothly along a predetermined path during the lifting process. The moving mechanism 532 is fixedly connected to the lifting plate 5314. When the lifting plate 5314 lifts the profile, the moving mechanism 532 can move horizontally on the lifting plate 5314 and move the profile to a designated position. The moving mechanism 532 includes a translation motor 5321, a threaded rod 5322 and a connecting frame 5323. The connecting frame 5323 is fixedly connected to the lifting mechanism 531. The translation motor 5321 is fixedly connected to one end of the connecting frame 5323. One end of the threaded rod 5322 is fixedly connected to the output end of the translation motor 5321. One end of the threaded rod 5322 away from the translation motor 5321 is rotatably connected to one end of the connecting frame 5323 away from the translation motor 5321 through a bearing. The material transport plate 533 is sleeved on the threaded rod 5322 and is rotatably connected to the threaded rod 5322. When the translation motor 5321 is started, its output end begins to rotate, and the threaded rod 5322 fixedly connected to the output end of the translation motor 5321 rotates accordingly. The material transport plate 533 mounted on the threaded rod 5322 will move linearly along its axial direction as the threaded rod 5322 rotates due to the threaded cooperation with the threaded rod 5322. By controlling the rotation direction and speed of the translation motor 5321, the linear movement distance and direction of the material transport plate 533 can be accurately controlled, thereby realizing the translation function.

[0046] The working principle of the profile straightening machine of this embodiment is as follows: First, the profile after straightening falls into the first storage rack 2. According to the shape of the profile to be loaded, a suitable holding fixture 333 is selected for installation. Then, the rotating device 32 is started to drive the clamping device 33 to rotate. According to the preset loading order, one of the clamping devices will first rotate to the first storage rack 2 to clamp the profile. At this time, the telescopic mechanism 331 starts to work and adjusts the position of the clamping mechanism 332 so that the holding fixture 333 can accurately contact the profile to be transferred. The clamping mechanism 332 is started and the profile is tightly clamped by the holding fixture 333. After clamping the profile, the rotary drive device 51 continues to work and rotates the profile to the conveying mechanism 34. At this time, the clamping mechanism 332 releases the clamping force of the holding fixture 333 on the profile, so that the profile can smoothly fall off from the clamping fixture. Then the profiles pass through the conveying mechanism 34 to the second storage rack 4. After a certain number of profiles are gathered, the moving mechanism 532 is controlled to make the material transport plate 533 contact with the batches of profiles, and the lifting mechanism 531 is started to lift the profiles. Then the moving mechanism 532 starts to work, and moves the material transport plate 533 and the profiles to the top of the first transmission mechanism 521. The lifting mechanism 531 is controlled to descend and the profiles are placed on the first transmission mechanism 521. Then the driving device 51 drives the third sub-rotor 5223 to rotate, and the third conveyor belt 5224 starts to move, and drives the first sub-rotor 5221 and the second sub-rotor 5222 to rotate. At this time, the first transmission mechanism 521 is started to transport the profiles to the profile separation transmission mechanism 522. The profiles are subjected to the thrust and gravity generated by the speed difference on the profile separation transmission mechanism 522, and the separated profiles are transported to the second transmission mechanism 523, and the profiles are further separated and transported.

[0047] The profile straightening machine in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the profile straightening machine realizes the full automation of the profile from straightening to punching, which not only greatly improves the production efficiency and quality stability, but also reduces the production cost and the risk of manual intervention.
