Description

Technical Field

[0001] The present application relates to the field of aluminum profile processing, and in particular to an automated aluminum profile processing device. Background Art

[0002] The processing technology of rod-shaped aluminum profiles is: forging - heat treatment - surface treatment - cutting - inspection and packaging.

[0003] In practice, aluminum profiles are typically cut by transferring them to a cutting device to obtain the desired length. The cuts are then transferred to a conveyor line for subsequent processing. This means the profiles must be transferred multiple times during the cutting process, resulting in low efficiency. Summary of the Invention

[0004] In order to improve the processing efficiency of aluminum profiles, the present application provides an automated processing device for aluminum profiles.

[0005] The present application provides an automated aluminum profile processing device that adopts the following technical solutions:

[0006] An automated processing device for aluminum profiles includes a first conveyor line, a second conveyor line, a cutting assembly and a clamping assembly, wherein a cutting gap exists between the first conveyor line and the second conveyor line; the cutting assembly includes a saw blade and a driving assembly for driving the saw blade to rise and fall; the clamping assembly is provided on the side where the first conveyor line and the second conveyor line are close to each other, and the conveyor line consists of a frame and conveying rollers distributed on the frame; the clamping assembly includes a clamping plate relatively slidably arranged on the frame and a pressing plate lifted and lowered on the frame.

[0007] By adopting the above technical solution, the rod-shaped aluminum profile is conveyed on the first conveyor line and the second conveyor line. After moving to a certain position, the conveyor line stops conveying. At this time, the two clamping plates slide toward each other to clamp the aluminum profile, and at the same time, the pressure plate descends to press the aluminum profile, so as to fix the position of the aluminum profile. Then the saw blade descends to cut the aluminum profile. After the cutting is completed, the two sections of aluminum profile continue to be conveyed, and the staff will inspect and package them at the end of the conveyor line. That is, in this way, the aluminum profile can be cut directly during the transportation process, without the need for transfer in the middle, which greatly saves time and helps to improve the processing efficiency of aluminum profiles.

[0008] Preferably, a clamping surface is formed on each side of the two clamping plates that are close to each other, and the clamping surfaces are inclined, and the two clamping surfaces are inclined from bottom to top in a direction away from each other.

[0009] By adopting the above technical solution, the clamping surface is set at an angle. When the inclined surface abuts against the aluminum profile, the clamping plate forms a supporting force on the aluminum profile in two directions, one of which is a vertical supporting force. This force component can share the supporting force of the conveyor roller on the aluminum profile, preventing the conveyor roller from being subjected to long-term stress and affecting its service life.

[0010] Preferably, a first cylinder is provided on the frame, and the end of the piston rod of the first cylinder is fixedly connected to a mounting plate, a sliding groove is provided on the mounting plate, and a sliding block is provided on the side of the clamping plate away from the clamping surface, the sliding block is slidably fitted in the sliding groove, and a return spring is provided in the sliding groove, one end of the return spring is connected to the bottom wall of the sliding groove, and the other end of the return spring is connected to the sliding block, and a locking member for locking the position of the sliding block is provided on the frame.

[0011] By adopting the above technical solution, the movement stroke of the piston rod is affected by the air pressure. If the air pressure is unstable, it may cause the movement to change, and then cause the aluminum profile to not abut against the movement. Therefore, the clamping plate and the mounting plate are slidably matched. The clamping plate first abuts against the aluminum profile, and then the cylinder will continue to push the mounting plate to slide. At this time, the return spring is compressed. In this way, even if the stroke of the cylinder changes, it will not affect the abutment between the clamping plate and the aluminum profile. The position of the sliding block is locked by the locking piece to prevent the clamping plate from slipping during the cutting process, thereby affecting the cutting effect.

[0012] Preferably, a mounting bracket is mounted on the frame, a second cylinder is vertically arranged on the mounting bracket, and the pressure plate is fixedly mounted on the end of the piston rod of the second cylinder.

[0013] By adopting the above technical solution, the second cylinder is operated to drive the pressing plate to descend, thereby achieving the pressing of the aluminum profile.

[0014] Preferably, the locking member is configured as a locking rod, which is fixedly mounted on one side of the pressure plate. A locking groove is provided on the sliding block, and when the pressure plate descends, the locking rod is plugged into and fitted into the locking groove.

[0015] By adopting the above technical solution, the position of the sliding block is locked through the cooperation of the locking rod and the locking groove, which can prevent the clamping plate from being displaced during the cutting operation and affecting the cutting effect of the aluminum profile.

[0016] Preferably, a receiving groove is provided on the side of the locking groove away from the second cylinder, a folding spring piece is provided in the receiving groove, the lower end of the folding spring piece is fixedly connected to the bottom wall of the receiving groove, the upper end of the folding spring piece is fixedly connected to a slider, and a sliding groove cooperating with the sliding of the slider is provided in the receiving groove; an abutment plate is fixedly connected to the locking rod, and when the locking rod is plugged into the locking groove, the abutment plate abuts against the slider and drives the slider to slide.

[0017] By adopting the above technical solution, after the locking rod is inserted into the locking groove, the abutment plate abuts against the slider and drives the slider to slide downward. At this time, the folding spring is compressed, and the edge of the folding spring will move toward the direction close to the locking rod, and then gradually abut against the locking rod. That is, in this way, the locking between the locking rod and the sliding block is achieved, which can prevent the sliding block, that is, the clamping plate, from offsetting, thereby ensuring the stability of the clamping of the aluminum profile.

[0018] Preferably, the bottom of the two clamping plates on the side close to each other is provided with an abutment block, and the two clamping plates move toward each other. When the two abutment blocks abut, the clamping plates stop moving; the clamping plates are provided with a compensation plate for sliding on the clamping surface, and the clamping plates are provided with a sliding groove at the clamping surface, and the compensation plate is provided with a sliding rod that slides with the sliding groove, and a compression spring is provided in the sliding groove, one end of the compression spring is connected to the bottom wall of the sliding groove, and the other end of the compression spring is connected to the sliding rod, and the clamping plate is provided with a positioning piece for positioning the sliding rod.

[0019] By adopting the above technical solution, the two clamping plates can be positioned by the abutment of the two abutment blocks, thereby ensuring that the locking rod and the locking groove are plugged in and matched. If the aluminum profile has a certain processing error or a certain change in size, the clamping plate cannot effectively abut against the aluminum profile. At this time, the elastically retractable compensation plate can ensure that the aluminum profile is tightly abutted, and after tightening, the sliding rod is locked by the positioning piece, which helps prevent vibration during the cutting process, causing the compensation plate to move, affecting the processing effect of the aluminum profile.

[0020] Preferably, a first locking tooth is provided on the side of the sliding rod, and the positioning member is provided as a second locking tooth, and the second locking tooth slides in a direction approaching and away from the first locking tooth.

[0021] By adopting the above technical solution, when the clamping plate finishes moving, the second locking tooth slides and engages with the first locking tooth, thereby achieving positioning and locking of the position of the sliding rod.

[0022] Preferably, a first mounting groove is provided in the sliding block, and a linkage rod is slidably connected in the first mounting groove, and a second mounting groove is provided in the clamping plate and communicates with the sliding groove, and a connecting rod is provided on the second locking tooth, and the connecting rod passes through the second mounting groove and extends into the first mounting groove, and an abutment spring is sleeved on the connecting rod, one end of the abutment spring is connected to the inner wall of the second mounting groove, and the other end of the abutment spring is connected to the first locking tooth; one end of the linkage rod extends into the locking groove, and a first wedge surface is formed at this end of the linkage rod, and a second wedge surface is formed at the other end of the linkage rod, and an abutment portion is formed on the end of the connecting rod that cooperates with the second wedge surface; an abutment spring is provided in the first mounting groove, one end of the abutment spring is connected to the inner wall of the first mounting groove, and the other end of the abutment spring is connected to the linkage rod.

[0023] By adopting the above technical solution, when the locking rod is plugged into the locking groove, the lower end of the locking rod cooperates with the first wedge surface, causing the linkage rod to slide, and the linkage rod cooperates with the second wedge surface and the abutment portion to cause the connecting rod to slide, that is, the second locking tooth slides, and the second locking tooth slides and engages with the first locking tooth to achieve positioning locking of the sliding rod position; when the cutting is completed, the pressure plate rises, synchronously driving the locking rod to rise, and under the action of the abutment spring, the linkage rod is reset, and then under the action of the abutment tension spring, the second locking tooth is reset and disengaged from the first locking tooth, and then the clamping plate slides to release the clamping action on the aluminum profile.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. This application sets the cutting assembly between the conveyor lines, and directly completes the cutting action on the aluminum profile conveying path, without the need for additional transportation of the aluminum profile, which greatly reduces the processing efficiency;

[0026] 2. The clamping surface of the clamping plate is inclined, which can also form a supporting force for the aluminum profile in the vertical direction, reducing the force on the conveyor roller and ensuring the life of the conveyor line;

[0027] 3. The clamping plate slides elastically on the mounting plate. When the cylinder stroke changes, the spring acts to keep the clamping plate pressed against the aluminum profile at all times. The locking rod and the locking groove cooperate to prevent the clamping plate from floating. When the locking rod and the locking groove are plugged in, the folded spring can compensate for the gap between the locking rod and the locking groove, so that the locking rod and the locking groove form an interference fit, thereby improving the locking effect of the locking rod on the sliding block.

[0037] The following is combined with Figures 1-8 This application is described in further detail.

[0038] The embodiment of the present application discloses an automated processing device for aluminum profiles.

[0039] Example 1

[0040] Reference Figure 1The automated aluminum profile processing apparatus includes a first conveyor line 1, a second conveyor line 2, a cutting assembly 3, and a clamping assembly 4. A cutting gap 5 is formed between the first conveyor line 1 and the second conveyor line 2. The first conveyor line 1 and the second conveyor line 2 constitute the entire conveyor line for aluminum profile processing, that is, the present application performs cutting operations while conveying aluminum profiles. Both conveyor lines are composed of a frame 21 and conveyor rollers 22 distributed on the frame 21.

[0041] The cutting assembly 3 includes a saw blade 31 and a driving assembly for driving the saw blade 31 to rise and fall. The driving assembly is configured as a screw slide 32. A door-shaped frame 51 is erected between the two conveyor lines. The screw slide 32 is mounted on the door-shaped frame 51. The saw blade 31 is disposed on the slide seat of the screw slide 32 and is rotated by a motor.

[0042] Reference Figure 1 and Figure 2 There are two clamping assemblies 4 corresponding to two conveyor lines. Taking one of the clamping assemblies 4 as an example, the clamping assembly 4 includes a clamping plate 41 slidingly arranged on the frame 21 and a pressing plate 42 lifting and lowering arranged on the frame 21.

[0043] During the production process, rod-shaped aluminum profiles are transported along the first and second conveyor lines 1 and 2. Once the ends of the profiles have moved to a certain position, the conveyor lines stop. Two sets of clamping plates 41 slide toward each other, clamping the profiles. Simultaneously, the pressure plate 42 moves downward to hold them in place. Once the profiles are positioned, the saw blade 31 descends to perform the cutting operation. The two sections of aluminum profile continue to move along the conveyor lines. Once the cut sections reach the end of the conveyor lines, they are inspected and packaged.

[0044] This process eliminates the intermediate transfer step by directly cutting during the aluminum profile transportation process, greatly shortens the processing time, and effectively improves the production and processing efficiency of aluminum profiles.

[0045] A clamping surface 411 is formed on each of the two clamping plates 41 , where the two clamping plates 41 are close to each other. The clamping surfaces 411 are inclined, and the two clamping surfaces 411 are inclined from bottom to top in a direction away from each other.

[0046] The clamping surface 411 is inclined. When the inclined surface contacts the aluminum profile, the clamping plate 41 exerts a supporting force in two directions. The vertical component of force helps to offset the load of the conveyor roller 22 on the aluminum profile, preventing the conveyor roller 22 from being subjected to excessive pressure over a long period of time, which could affect its service life. This structural design optimizes the support system by leveraging the principle of mechanical force distribution, ensuring stable clamping of the aluminum profile while effectively extending the service life of the conveyor roller 22.

[0047] Reference Figure 2 、 Figure 3 and Figure 4A first cylinder 6 is installed on the frame 21, and the end of the piston rod of the first cylinder 6 is fixedly connected to a mounting plate 61. A sliding groove 611 is provided on the mounting plate 61. A sliding block 7 is integrally formed on the side of the clamping plate 41 away from the clamping surface 411. The sliding block 7 slides and fits with the sliding groove 611. A return spring 612 is provided in the sliding groove 611. One end of the return spring 612 is connected to the bottom wall of the sliding groove 611, and the other end is connected to the sliding block 7. A locking member for locking the sliding block 7 is provided on the frame 21.

[0048] Since the movement stroke of the piston rod is affected by air pressure, if the air pressure is unstable, the stroke may change, and then the clamping plate 41 may not contact the aluminum profile. For this reason, a structural design of sliding fit between the clamping plate 41 and the mounting plate 61 is adopted: after the clamping plate 41 contacts the aluminum profile first, the cylinder continues to push the mounting plate 61 to slide, and at this time the reset spring 612 is compressed. This design can prevent the contact state between the clamping plate 41 and the aluminum profile from being affected by the fluctuation of the cylinder stroke. Even if the cylinder stroke changes, the elastic compensation effect of the reset spring 612 can ensure that the clamping plate 41 always maintains the contact state. In addition, by locking the position of the sliding block 7 with a locking piece, the clamping plate 41 can be effectively prevented from displacement during the cutting process, avoiding the impact of unstable clamping on the cutting accuracy, thereby ensuring the cutting quality of the aluminum profile.

[0049] Reference Figure 2 and Figure 3 The frame 21 is provided with a mounting frame 211, on which the second cylinder 8 is mounted. The second cylinder 8 is arranged vertically downward, and the end of the piston rod of the second cylinder 8 is fixedly connected to the connecting plate 81. The pressing plate 42 is fixedly mounted on the connecting plate 81. After the clamping plate 41 clamps the aluminum profile, the second cylinder 8 is operated, driving the pressing plate 42 to descend and press the aluminum profile.

[0050] The locking member is provided as a locking rod 9, which is arranged vertically. The upper end of the locking rod 9 is fixedly connected to the connecting plate 81, that is, located on one side of the pressure plate 42. The sliding block 7 is provided with a locking groove 71. When the pressure plate 42 descends, the locking rod 9 gradually forms a plug-in fit with the locking groove 71. The locking rod 9 and the locking groove 71 cooperate to lock the position of the sliding block 7, preventing the clamping plate 41 from shifting during the cutting process, which would affect the cutting effect.

[0051] The implementation principle of the automated aluminum profile processing device of the embodiment of the present application is as follows: the rod-shaped aluminum profile is conveyed from the first conveyor line 1 to the second conveyor line 2. At the end of the second conveyor line 2, another process is performed. During the conveying process of the aluminum profile, after conveying a certain distance, the conveying is stopped. At this time, the clamping plate 41 moves to clamp the aluminum profile, and then the pressure plate 42 descends to press the aluminum profile. Finally, the saw blade 31 descends to cut the aluminum profile. After the cutting is completed, the conveyor line continues to convey, and then the above operation is repeated. In this way, there is no need to transfer the aluminum profile midway for separate cutting operations, which greatly improves the overall processing efficiency of the aluminum profile.

[0052] Example 2

[0053] Reference Figure 5 The difference between this embodiment and embodiment 1 is that a receiving groove 72 is provided on the side of the locking groove 71 away from the second cylinder 8, and a folding spring piece 10 is provided in the receiving groove 72. The folding spring piece 10 is composed of several W-shaped pieces. The lower end of the folding spring piece 10 is fixedly connected to the bottom wall of the receiving groove 72, and the upper end of the folding spring piece 10 is fixedly connected to the slider 101. A sliding groove 721 that slides with the slider 101 is provided in the receiving groove 72; an abutment plate 91 is fixedly connected to the locking rod 9. When the locking rod 9 is plugged into the locking groove 71, the abutment plate 91 abuts against the slider 101 and drives the slider 101 to slide.

[0054] When the locking rod 9 is inserted into the locking slot 71, the abutment plate 91 contacts the slider 101 and pushes it downward, compressing the folding spring 10. During this compression process, the edge of the folding spring 10 moves toward the locking rod 9, gradually abutting against it, thereby locking the locking rod 9 and the sliding block 7. This structural design effectively prevents the sliding block 7 and the clamping plate 41 from shifting, ensuring the stability of the aluminum profile during the clamping process and providing reliable positioning for subsequent cutting operations.

[0055] Example 3

[0056] Reference Figure 7 and Figure 8 This embodiment differs from Embodiment 2 in that an abutment block 412 is fixedly connected to the bottom of each of the two clamping plates 41 on the side where they approach each other. When the two clamping plates 41 move toward each other, the clamping plates 41 stop moving after the abutment blocks 412 abut. A sliding groove 20 is defined on the clamping surface 411 of the clamping plate 41. A sliding rod 30 is slidably connected within the sliding groove 20. A compensation plate 301 is provided at the end of the sliding rod 30. A compression spring 201 is provided within the sliding groove 20. One end of the compression spring 201 is connected to the bottom wall of the sliding groove 20, and the other end is connected to the sliding rod 30. A positioning member is provided on the clamping plate 41 to locate the position of the sliding rod 30.

[0057] By abutting the two abutment blocks 412, the positions of the two clamping plates 41 can be positioned, thereby ensuring the precise insertion and fit of the locking rod 9 and the locking groove 71. If there are processing errors or dimensional fluctuations in the aluminum profile, the clamping plate 41 may not be able to effectively abut the aluminum profile. At this time, the elastically retractable compensation plate 301 can achieve adaptive tightening of the aluminum profile. After the compensation plate 301 is pressed against the aluminum profile, the positioning member is used to lock the sliding rod 30, which can avoid the displacement of the compensation plate 301 due to vibration during the cutting process, thereby ensuring that the processing accuracy of the aluminum profile is not affected. This structural design solves the problem of abutment failure caused by dimensional deviation through the dual mechanisms of elastic compensation and rigid locking, and can maintain a stable clamping state during the processing, effectively improving the reliability of aluminum profile cutting.

[0058] A first locking tooth 73 is provided on the side of the sliding rod 30, and the positioning piece is set as a second locking tooth 40. The second locking tooth 40 slides in a manner close to and away from the first locking tooth 73. The second locking tooth 40 slides and engages with the first locking tooth 73 to achieve the positioning locking of the position of the sliding rod 30.

[0059] A first mounting slot 50 is defined within the sliding block 7. The end of the first mounting slot 50 extends into the clamping plate 41. A linkage rod 60 slidably engages within the first mounting slot 50. A second mounting slot 60 communicating with the sliding slot 20 is defined within the clamping plate 41. A second locking tooth 40 slidably engages with the second mounting slot 60. A connecting rod 401 is fixedly connected to one side of the second locking tooth 40. The connecting rod 401 is located within the second mounting slot 60 and then passes through the second mounting slot 60 into the first mounting slot 50. An abutting tension spring 402 is sleeved on the connecting rod 401. One end of the abutting tension spring 402 is connected to the inner wall of the second mounting slot 60, and the other end is connected to the first locking tooth 73. One end of the linkage rod 60 extends into the locking groove 71, and the linkage rod 60 is located below the accommodating groove 72, and a first wedge surface 601 is formed at this end of the linkage rod 60, and a second wedge surface 602 is formed at the other end of the linkage rod 60. The end of the connecting rod 401 is formed with an abutment portion that cooperates with the second wedge surface 602, and an abutment spring 501 is provided in the first mounting groove 50, one end of the abutment spring 501 is connected to the inner wall of the first mounting groove 50, and the other end is connected to the linkage rod 60.

[0060] When the locking rod 9 is inserted into the locking slot 71, its lower end engages with the first wedge surface 601, causing the linkage rod 60 to slide. The linkage rod 60, through the cooperation of the second wedge surface 602 and the abutment portion, drives the connecting rod 401 to slide, thereby displacing the second locking tooth 40. When the second locking tooth 40 slides and meshes with the first locking tooth 73, the sliding rod 30 is locked in place.

[0061] After the cutting operation is completed, the pressure plate 42 rises, driving the locking rod 9 upwards. Under the action of the abutment spring 501, the linkage rod 60 returns to its initial position. Subsequently, under the tension of the abutment tension spring 402, the second locking tooth 40 returns to its original position and disengages from the first locking tooth 73. Finally, the clamping plate 41 slides, releasing its grip on the aluminum profile.

[0062] This locking and unlocking mechanism achieves precise control and stable locking of the position of the sliding rod 30 through a multi-structure design of wedge surface transmission, spring return and tooth engagement. It can not only ensure the reliability of aluminum profile clamping during the cutting process, but also quickly release the lock after the operation is completed, ensuring the continuity and efficiency of the production process.

[0063] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
