[0002] Rolled aluminum profile is an aluminum material produced by the rolling process. The rolling process refers to heating the aluminum ingot or billet to a certain temperature and then forming it into an aluminum profile of the desired shape and size through multiple rolling, stretching and other processing methods.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The utility model provides a technical solution: Figure 1-5 The utility model discloses a bending device for producing rolled aluminum profiles, comprising a bending die 1 installed at the bending drive end of the bending device and a first clamping block 2 and a second clamping block 3 respectively installed at the two clamping drive ends of the bending device. The cross-section of the second clamping block 3 is L-shaped, a support plate 4 is provided in the mounting groove of the second clamping block 3, and a limit member 5 is provided between the support plate 4 and the inner wall of the mounting groove of the second clamping block 3. The support plate 4 is composed of a plurality of rectangular rods 41, and two adjacent rectangular rods 41 are connected by an elastic member 42, and the support plate 4 is connected to the first clamping block 2 by a connecting member 6.

[0022] In this embodiment, when the bending device performs the bending operation of the rolled aluminum profile, the feeding mechanism of the bending device pushes the rolled aluminum profile into the groove of the bending die 1, and then the two clamping mechanisms of the bending device push the first clamping block 2 and the second clamping block 3 into the groove of the rolled aluminum profile. At this time, the first clamping block 2, the second clamping block 3, the support plate 4 and the limiting plate 12 clamp and limit part of the rolled aluminum profile from the inner and outer sides of the rolled aluminum profile to constrain and orient the side wall of part of the rolled aluminum profile, and then the first clamping block 2 and the bending die 1 are rotated to The rolled aluminum profile is bent. During the bending process of the rolled aluminum profile, due to the pulling of the rectangular rod 41 by the first clamp 2 and the bending deformation of the elastic member 42, the rectangular rod 41 is moved out of the mounting groove of the second clamp 3. The rectangular rod 41 is located in the groove of the rolled aluminum profile and cooperates with the bending mold 1 to clamp and limit the side wall of the rolled aluminum profile, thereby constraining and shaping the side wall of the bent part of the rolled aluminum profile. During the bending process of the rolled aluminum profile, the side wall of the rolled aluminum profile will not bend and deform, which will affect the bending effect of the aluminum profile.

[0023] In a further preferred embodiment of the present invention, Figure 1 As shown, the bending die 1 comprises a round rod 11 with an I-shaped cross section, a limiting plate 12 with a concave cross section is fixedly mounted on the outer circumference of the round rod 11, and the inner groove height of the limiting plate 12 is equal to the height of the wheel groove of the round rod 11;

[0024] In this embodiment, after the above-mentioned rolled aluminum profile is pushed into the groove of the bending mold 1, due to the mutual interference between the side walls of the round rod 11 and the side walls of the limiting plate 12 and the outer side walls of the rolled aluminum profile, the two side walls of the rolled aluminum profile can be constrained and limited by the outer side of the rolled aluminum profile, so that the two side walls of the rolled aluminum profile will bend and deform outside the rolled aluminum profile.

[0025] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the first clamping block 2 is arranged in a rectangular block shape, and the height of the first clamping block 2, the height of the second clamping block 3 and the height of the support plate 4 are smaller than the wheel groove height of the round rod 11;

[0026] In this embodiment, after the first clamp block 2, the second clamp block 3 and the support plate 4 are inserted into the groove of the rolled aluminum profile, the two side walls of the rolled aluminum profile will not bend and deform like in the pressed groove due to the mutual interference between the first clamp block 2, the second clamp block 3 and the support plate 4 and the inner wall of the rolled aluminum profile.

[0027] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 and Figure 5As shown, the connecting member 6 includes a connecting block 62 with a T-shaped cross section, one end of the support plate 4 is fixedly connected to the inner wall of the mounting groove of the second clamping block 3, a connecting groove 61 with a T-shaped cross section is provided in the first clamping block 2, and one end of the connecting block 62 is located in the connecting groove 61 and contacts the inner wall of the connecting groove 61, and the other end of the connecting block 62 is fixedly connected to the other end of the support plate 4;

[0028] In this embodiment, during the process of the two clamping mechanisms of the bending device pushing the first clamping block 2 and the second clamping block 3 into the groove of the rolled aluminum profile, as the first clamping block 2 and the second clamping block 3 are merged, the connecting block 62 can be inserted into the connecting groove 61, so that during the rotation of the first clamping block 2, the end of the support plate 4 close to the first connecting block 62 is synchronously pulled to rotate synchronously through the mutual interference between the connecting block 62 and the inner wall of the connecting groove 61.

[0029] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the elastic member 42 includes a plurality of elastic rods 421, and the elastic rods 421 are arranged between the corresponding two rectangular rods 41. A slide groove 422 with a T-shaped cross section is opened at the position corresponding to the elastic rod 421 in the rectangular rod 41. Both ends of the elastic rod 421 are inserted into the corresponding slide groove 422 and are slidably connected with the inner wall of the corresponding slide groove 422. Both ends of the elastic rod 421 are fixedly installed with a piston plate 423, and the outer peripheral wall of each piston rod is in contact with the inner wall of the corresponding slide groove 422.

[0030] In this embodiment, during the process of the first clamping block 2 pulling the support plate 4 to rotate synchronously, the angle between the rectangular rods 41 changes, so that the various parts of the support plate 4 are bent and deformed with different arcs, so that the support plate 4 is always located in the groove of the rolled aluminum profile. At the same time, part of the rectangular rods 41 are pulled out of the slide groove 422 and adaptively bent and deformed, so that the piston plate 423 moves toward the opening direction of the slide groove 422, thereby forming a negative pressure chamber in the slide groove 422.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, the stopper 5 includes a first magnetic plate 51, which is fixedly mounted at a position of the first clamping block 2 corresponding to the rectangular rod 41, and a second magnetic plate 52 is fixedly mounted at a position of the rectangular rod 41 corresponding to the first magnetic plate 51;

[0032] In this embodiment, after the bending operation of the above-mentioned rolled aluminum profile is completed, the two clamping mechanisms of the bending device contact the first clamping block 2 and the second clamping block 3 to clamp and limit the rolled aluminum profile. At this time, due to the pulling of the piston plate 423 by the negative pressure chamber in the slide groove 422, the deformation restoration of the elastic rod 421 and the mutual attraction between the first magnetic plate 51 and the second magnetic plate 52, the bent support plate 4 returns to a straight state and fits on the inner wall of the mounting groove of the second clamping block 3.

[0033] Working principle: When the bending device is bending the rolled aluminum profile, the feeding mechanism of the bending device pushes the rolled aluminum profile into the wheel groove of the round rod 1 and the groove of the limit plate 12, and then the two clamping mechanisms of the bending device push the first clamping block 2 and the second clamping block 3 into the groove of the rolled aluminum profile. At this time, the first clamping block 2, the second clamping block 3, the support plate 4 and the limit plate 12 clamp and limit part of the rolled aluminum profile from the inner and outer sides of the rolled aluminum profile to avoid bending deformation of the rolled aluminum profile;

[0034] It should be noted that, in the process of the first clamping block 2 and the second clamping block 3 gradually approaching and being level, the connecting block 62 can be driven to be inserted into the connecting groove 61, so that the first clamping block 2 and the support plate 4 are connected together through the mutual interference between the connecting block 62 and the inner wall of the connecting groove 61;

[0035] As the bending die 1 and the first clamping block 2 rotate, the bending equipment bends part of the rolled aluminum profile into a specific curvature. In the subsequent bending process of the rolled aluminum profile, the first clamping block 2 pulls the support plate 4, causing the support plate 4 to bend and deform, so that the support plate 4 will not be pulled out of the inner groove of the rolled aluminum profile. The two ends of the plurality of rectangular rods 41 cooperate with the round rods 11 to clamp and constrain the two side walls of the rolled aluminum profile, so that the side walls of the aluminum profile will not bend and deform during the bending process of the rolled aluminum profile.

[0036] It should be noted that as the rolled aluminum profile is bent, the spacing between the rectangular rods 41 changes accordingly. At this time, part of the rectangular rods 41 are pulled out of the slide groove 422 and adaptively bent and deformed, so that the piston plate 423 moves toward the opening direction of the slide groove 422, thereby forming a negative pressure chamber in the slide groove 422.

[0037] After the bending operation of the rolled aluminum profile is completed, the two clamping mechanisms of the bending device contact the first clamping block 2 and the second clamping block 3 to clamp and limit the rolled aluminum profile. At this time, due to the pulling of the piston plate 423 by the negative pressure chamber in the slide groove 422, the deformation restoration of the elastic rod 421 and the mutual attraction between the first magnetic plate 51 and the second magnetic plate 52, the bent support plate 4 restores its straight state and fits on the inner wall of the mounting groove of the second clamping block 3. According to the above repeated operations, the bending operation of the rolled aluminum profile can be performed continuously.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model.
