Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, specifically a bending device for aluminum profile processing. Background Technology

[0002] In the field of aluminum profile processing, bending aluminum profiles is a common processing requirement, widely used in construction, furniture, transportation, and many other industries. Traditional aluminum profile bending devices, such as the one disclosed in Chinese Utility Model Patent Application No. 202323309224.4, use a clamping mechanism with clamping grooves to fix the aluminum profile and a hydraulic cylinder to drive the bending head to perform the bending operation. This device achieves adaptive clamping of aluminum profiles of different lengths by placing the aluminum material horizontally on the bottom inner walls of the two clamping grooves.

[0003] However, in practical applications, for some aluminum profiles, the processing requirements may only necessitate bending a specific area, while the remaining portion needs to maintain its original straight state, forming special structures such as a V-shape. However, existing bending devices, which only limit movement at both ends, can easily cause unnecessary overall bending of the aluminum profile in the middle of the clamping groove when the bending head is pressed down, thus affecting processing accuracy and product quality. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a bending device for aluminum profile processing to solve the problems in the background technology.

[0005] This utility model provides the following technical solution: a bending device for aluminum profile processing, including a base, a bending head mechanism disposed on the base, and a bending guide mechanism disposed on the base;

[0006] The bending head mechanism includes a bending plate that is vertically and movably disposed above the base;

[0007] The bending guide mechanism:

[0008] It includes profile support plates symmetrically arranged on both sides of the bending head mechanism for supporting aluminum profiles from the bottom, an upper limit structure arranged above the profile support plates for limiting the upper part of the aluminum profile, and a side limit structure arranged on the profile support plates for limiting the aluminum profile from the side.

[0009] A guiding structure that directs the profile support plate during bending;

[0010] The guiding structure includes horizontal guide rails fixed on both sides above the base and two vertical guide rails fixed on the base. Two shafts are fixed at both ends of the profile support plate. Two connecting blocks are rotatably connected to the two shafts. The two connecting blocks are slidably disposed in the horizontal guide rails and vertical guide rails respectively. A driving mechanism for driving the connecting blocks to slide is installed in the horizontal guide rails and vertical guide rails.

[0011] Compared with existing technologies, the advantages of this invention are as follows: Existing aluminum profile bending devices process aluminum profiles by clamping them at both ends and bending them in the middle, which easily leads to overall bending of the aluminum profile and affects processing accuracy. This invention, through the setting of the bending head mechanism and the guidance of the guiding mechanism, can maintain the straightness of both ends of the aluminum profile during the bending process, while automatically forming a V-shaped structure on the profile support plate. This allows for precise control of the bending area, effectively avoiding overall bending and significantly improving processing accuracy and product quality. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention relates to a bending device for processing aluminum profiles, comprising a base 1, a bending head mechanism 2 disposed on the base 1 for bending aluminum profiles 3, and a bending guide mechanism 4 disposed on the base 1 for limiting and guiding aluminum profiles 3 during bending.

[0019] The bending head mechanism 2 includes a bending plate 22 that is vertically and movably disposed above the base 1. A telescopic cylinder 21 is connected between the upper end of the bending plate 22 and the base 1. When the telescopic cylinder 21 extends, it can drive the bending plate 22 to move downward. When the bending plate 22 moves downward, it bends the aluminum profile 3 that is limited on the bending guide mechanism 4.

[0020] The bending guide mechanism 4 includes:

[0021] Symmetrically arranged on both sides of the bending head mechanism 2 are profile support plates 41 for supporting the aluminum profile 3 from the bottom, an upper limit structure 42 for limiting the upper part of the aluminum profile 3 above the profile support plates 41, and a side limit structure 43 for limiting the aluminum profile 3 from the side on the profile support plates 41. Through the arrangement of the profile support plates 41, upper limit structure 42, and side limit structure 43, the shape of the aluminum profile 3 is maintained during bending. It can be understood that the connection between the profile support plates 41, upper limit structure 42, and side limit structure 43 and the aluminum profile 3 is a movable connection. That is, during bending, the two ends of the aluminum profile 3 can move relative to the profile support plates 41, upper limit structure 42, and side limit structure 43. Here, the function of the profile support plates 41, upper limit structure 42, and side limit structure 43 is to keep the two ends of the aluminum profile 3 in a straight state.

[0022] The guiding structure that guides the profile support plate 41 during bending can be understood as follows: because the aluminum profile 3 is limited on both sides by the profile support plate 41, the upper limit structure 42 and the side limit structure 43, the aluminum profile 3 will gradually form a V-shaped structure when it is squeezed by the bending plate 22, and the guiding structure is used to guide the movement of the profile support plate 41.

[0023] It is worth mentioning that, in order to facilitate the formation of the V-shaped structure when the aluminum profile 3 is bent, a notch 31 can be made at the part of the aluminum profile 3 that needs to be bent before bending.

[0024] Please refer to the following: Figure 2 , Figure 4 as well as Figure 5The guiding structure includes horizontal guide rails 441 fixed horizontally on both sides above the base 1 and two vertical guide rails 442 fixed vertically on the base 1. Two shafts 443 are fixed to both ends of the profile support plate 41. The two shafts 443 are rotatably connected to two connecting blocks 444. The two connecting blocks 444 are slidably disposed within the horizontal guide rails 441 and the vertical guide rails 442, respectively. During bending, the two ends of the profile support plate 41, through the arrangement of the shafts 443 and the connecting blocks 444, can respectively be positioned within the horizontal guide rails 441 and 442. And the vertical guide rail 442 slides inside. For example, when the middle part of the aluminum profile 3 is pressed downward by the bending plate 22, the end of the profile support plate 41 near the bending mechanism 2 will move downward under the guidance of the vertical guide rail 442, while the end of the profile support plate 41 away from the bending mechanism 2 will move towards the bending mechanism 2 under the guidance of the vertical guide rail 442. The two profile support plates 41 move together to form a V-shaped structure, which maintains the shape of the aluminum profile 3 and prevents the aluminum profile 3 from bending as a whole.

[0025] Furthermore, such as Figure 4 As shown, a drive mechanism 445 for driving the connecting block 444 to slide is installed in the horizontal guide rail 441 and the vertical guide rail 442. The function of the drive mechanism 445 is to drive the connecting block 444 to move. Under the drive of the drive mechanism 445, the two sets of profile support plates 3 are synchronized and maintain stable movement, thereby better limiting the bending process of the aluminum profile 3.

[0026] In some embodiments, the upper limit structure 42 is a limiting wheel structure that is rotatably disposed above the profile support plate 41, and the limiting wheel structure is equidistantly disposed along the length direction of the profile support plate 41.

[0027] In some embodiments, the side limiting structure 43 includes a clamping plate 432 movably disposed on one side of the profile support plate 41 and a clamping cylinder 431 connected between the profile support plate 41 and the clamping plate 432. A baffle is fixed on the other side of the profile support plate 41, and a shaft 443 is fixed on the surface of the baffle. After the aluminum profile 3 is placed on the surface of the profile support plate 41, the clamping cylinder 431 extends to push the clamping plate 432 to move, so that the aluminum profile 3 reaches the bottom of the limiting wheel structure and the other side of the aluminum profile abuts against the upper limit of the baffle.

[0028] In some embodiments, the drive mechanism 445 is a motor lead screw drive mechanism.

[0029] In summary, this utility model aims to provide a bending device for aluminum profile processing. This device, through the design of a bending guide mechanism 4, including a profile support plate 41, an upper limit structure 42, a side limit structure 43, and a guide structure, can ensure that specific areas of the aluminum profile 3 are precisely bent while maintaining the straightness of the remaining parts during bending, thus avoiding unnecessary overall bending and improving processing accuracy and product quality.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
