Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy profile production, and more particularly to a device for automatically adjusting the length of cut and extruded aluminum alloy profiles. Background Art

[0002] In aluminum alloy extrusion production, the finished product is often formed from a round cast bar of fixed specifications after being deformed under high temperature and high pressure and passed through a mold cavity with a specific shape. The resulting extruded product can be as short as ten meters or as long as more than fifty meters, far exceeding the specified length required by the client.

[0003] Currently, to ensure the cutting quality and length requirements of aluminum alloy profiles, manual measurement and adjustment of the baffle to the appropriate distance are performed. After a cut, the remaining profile is moved forward by rollers. When the head of the profile hits the baffle, it is considered the required length. However, collisions with large and heavy aluminum alloy profiles often cause the baffle position to shift. This necessitates constant manual adjustment of the distance between the baffle and the saw blade and re-checking the finished product size. This results in time-consuming and labor-intensive cutting, low work efficiency, and inconsistent cut lengths, impacting customer experience.

[0004] Therefore, there is an urgent need for a device that can automatically adjust the length of cut and extruded aluminum alloy profiles. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a device for automatically adjusting the length of cut extruded aluminum alloy profiles, so as to solve the problem that the length of the finished product needs to be re-inspected and the position of the baffle needs to be repeatedly adjusted in the existing cutting method.

[0008] To further optimize the technical solution, the cutting mechanism includes a vertically arranged saw blade, the saw blade is connected to a cutting motor, and the cutting motor is connected to a PLC operation panel; a protective shell is provided outside the saw blade, and a collection mechanism for collecting cut aluminum chips is provided on the protective shell.

[0009] To further optimize the technical solution, the collection mechanism includes an aluminum chip collection pipe connected to the protective shell, a fan is connected to the aluminum chip collection pipe, and the other end of the aluminum chip collection pipe is connected to a collection bag.

[0010] To further optimize the technical solution, the collection bag is a high-density collection bag.

[0011] To further optimize the technical solution, the positioning mechanism includes a horizontally arranged slide rail set on a support frame, and a vertically arranged baffle is connected to the slide rail through a slider; the baffle is connected to a DC drive motor through a rack, and the controlled end of the DC drive motor is connected to a PLC operation panel; a pneumatic locking device for fixing the position of the baffle is provided on the slide rail, and the pneumatic locking device is connected to an air pipe.

[0012] To further optimize the technical solution, the outer surface of the roller is wrapped with a layer of felt fibers for increasing friction.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is as follows.

[0014] This utility model provides a device that automatically adjusts the length of cut and extruded aluminum alloy profiles. The PLC on the operating panel compares the set value with the data measured by the photoelectric sensor. Based on the comparison result, the baffle plate is adjusted to move forward and backward, offsetting changes in cutting length caused by baffle plate displacement due to impact, reducing the need for repeated manual length checks. A pneumatic locking device replaces the manual bolting required to secure the baffle plate. An aluminum chip collection device operates when the saw blade is activated, reducing aluminum chip splashing during cutting. This utility model offers the advantages of high automation, high efficiency, high precision, and labor savings. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] A device for automatically adjusting the length of cut and extruded aluminum alloy profiles, combined with Figure 1As shown, it includes a cutting platform, a collection mechanism, a PLC operation panel 6, a positioning mechanism, and a photoelectric sensor 8; the cutting platform includes a support frame 12, a roller 2, and a synchronous belt 3; the collection mechanism includes an aluminum chip collection pipe 51 and a collection bag 52; the collection mechanism includes a saw blade 7, a protective shell 14, and a collection mechanism; the positioning mechanism includes a baffle 10, a slide rail 11, a DC drive motor 13, an air pipe 15, and a pneumatic locking device 9.

[0019] The cutting platform is connected to the cooling bed 1 at the same height. The cutting platform includes a support frame 12, mounted with several rollers 2. These rollers 2 are used to transport the profiles 4 onto and off the cooling bed 1. The rollers 2 are coated with a layer of felt fiber to increase friction and prevent scratches on the aluminum alloy profiles 4 during transport. Several timing belts 3 are connected between the rollers 2 to ensure synchronous motion. These timing belts 3 are connected to the power motor that provides the driving force.

[0020] A cutting mechanism is located in the middle of the support frame 12, with the controlled end of the cutting mechanism connected to the PLC operation panel 6. The cutting mechanism includes a vertically mounted saw blade 7, which is connected to a cutting motor, which is connected to the PLC operation panel 6. A protective shell 14 is provided around the saw blade 7 to increase safety during use.

[0021] The cutting mechanism is provided with a collection mechanism, which is mounted on the protective shell 14 and is used to collect aluminum chips from cutting. The collection mechanism includes an aluminum chip collection pipe 51 connected to the protective shell 14. A fan is connected to the aluminum chip collection pipe 51. The other end of the aluminum chip collection pipe 51 is connected to a collection bag 52. The collection bag 52 is a high-density collection bag to prevent fine aluminum chips from flying.

[0022] A positioning mechanism is located at the right end of the support frame 12, the input of which is connected to the PLC operation panel 6. This positioning mechanism comprises a horizontally positioned slide rail 11 mounted on the support frame 12. A vertically positioned baffle 10 is connected to the slide rail 11 via a slider. This baffle 10 is connected to a DC drive motor 13 via a rack, and the controlled end of the DC drive motor 13 is connected to the PLC operation panel 6. A pneumatic locking device 9 is installed on the slide rail 11 to secure the position of the baffle 10. This pneumatic locking device 9 is connected to an air pipe 15, which is in turn connected to an air source.

[0023] A photoelectric sensor 8 is provided on the cutting mechanism, and the output end of the photoelectric sensor 8 is connected to the PLC operation panel 6. The photoelectric sensor 8 is installed outside the saw blade protection shell 14. There is an inevitable gap between the photoelectric sensor 8 and the saw blade. Therefore, it is necessary to manually enter the gap length on the PLC operation panel 6 for compensation.

[0024] When the present invention is actually used, the required cutting length is input on the PLC operation panel, the DC drive motor 13 is started, the baffle 10 slides to a fixed position on the slide rail 11, and the photoelectric sensor 8 detects the distance between the baffle 10 and the pneumatic locking device 9 and locks the baffle 6 position manually after the data is correct.

[0025] The roller synchronous belt 3 drives the aluminum profile to move forward until it collides with the baffle 10. The saw blade 7 starts, the cutting of the aluminum profile 4 begins, and the aluminum chip collection device 5 starts synchronously. The strong suction force sucks away the cut aluminum chips and collects them into the waste bag.

[0026] After the aluminum profile 4 is cut, it is removed. Roller 2 and timing belt 3 drive the aluminum profile forward until it collides with baffle 10. If the impact force is too great, causing baffle 10 to shift forward, photoelectric sensor 8 detects that the length exceeds the set value, and saw blade 7 cannot be activated. The PLC on the operation panel unlocks baffle 10, and drive motor 13 drives baffle 10 backward to adjust the position. Cutting will not resume until the data from photoelectric sensor 8 matches the set value.
