Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to a straightening machine. Background Art

[0002] Aluminum profiles usually refer to aluminum alloy profiles. Aluminum profiles have excellent machinability. When processing longer aluminum profiles, a certain amount of deformation is prone to occur, and they need to be straightened by a straightening device to facilitate subsequent processing.

[0003] The existing aluminum profile straightening device includes a straightening bracket and a clamping mechanism. The clamping mechanism is used to clamp the aluminum profile. A guide rail is arranged on the straightening bracket, and the clamping mechanism can slide on the guide rail. When straightening, the clamping mechanism clamps the aluminum profile to be straightened, and the clamping mechanism is tightened to both sides under the drive of the driving member to straighten the aluminum profile.

[0004] Although the existing straightening mechanism can complete the straightening work, most of the straightening mechanisms can only rely on pulling force for straightening. When the angle of the aluminum profile is offset, it needs to be rotated and corrected by the correction mechanism after straightening, which increases the processing steps and increases the processing cost. Therefore, a straightening device that can directly perform correction work after completing the straightening work is needed. Utility Model Content

[0032] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0033] like Figures 1 to 12 As shown, the utility model provides a straightening machine, including a straightening bracket 1, on which a straightening mechanism 3 and a correction mechanism 2 are arranged, the straightening mechanism 3 is used to clamp the aluminum profile for straightening, and the correction mechanism 2 is used to clamp the aluminum profile and perform rotation correction;

[0034] The correction mechanism 2 includes a correction bracket 20, a correction disk 22, a correction drive 27, a correction chuck 21 and a sliding drive 23. The sliding drive 23 is used to drive the correction chuck 21 to slide on the correction disk 22. The correction disk 22 is hinged on the correction bracket 20. The correction drive 27 is used to drive the correction disk 22 to rotate on the correction bracket 20.

[0035] In this embodiment, a first clamping plate 25, a first tooth 26 and a first locking drive member 24 are provided on the correcting chuck 21. The first tooth 26 is hinged to the correcting chuck 21. The first clamping plate 25 and the first locking drive member 24 are fixedly installed on the correcting chuck 21. The first locking drive member 24 is used to drive the first tooth 26 to approach or move away from the first clamping plate 25.

[0036] Through the above-mentioned design scheme, when straightening work is performed, the first biting tooth 26 is driven by the first locking drive member 24 to slowly swing down and approach the first clamping plate 25 until the aluminum profile is clamped, and then the axis position of the aluminum profile is determined according to the data of the aluminum profile. Under the drive of the sliding drive member 23, the correction chuck 21 is automatically adjusted to make the axis of the aluminum profile coincide with the axis of the correction disk 22, and then the correction drive member 27 is started to drive the correction disk 22 to rotate with the axis as the center of the circle to complete the correction work of the aluminum profile.

[0037] In this embodiment, the straightening mechanism 3 includes a tensioning drive 30, a slide 31, a straightening chuck 32 and a lifting drive 33. The tensioning drive 30 is fixedly installed on the straightening bracket 1. The tensioning drive 30 can drive the slide 31 to slide on the straightening bracket 1. A lifting drive 33 is installed on the slide 31. The lifting drive 33 is used to drive the straightening chuck 32 to rise or fall on the slide 31.

[0038] In this embodiment, a second clamping plate 34, a second biting tooth 35 and a second locking drive member 38 are provided on the straightening chuck 32. The second locking drive member 38 is hinged to the straightening chuck 32. The second locking drive member 38 is used to drive the second biting tooth 35 hinged on the straightening chuck 32 to move closer to or away from the second clamping plate 34 fixedly installed on the straightening chuck 32.

[0039] Through the above-mentioned design scheme, when straightening work is performed, the second biting tooth 35 can clamp the aluminum profile in cooperation with the second clamping plate 34 under the drive of the second locking drive member 38, and then the lifting drive member 33 controls the straightening chuck 32 to lift, so that the first clamping plate 25 and the second clamping plate 34 are in the same horizontal plane, and then the tensioning drive member 30 drives the slide 31 away from the correction mechanism 2, and the aluminum profile is straightened simultaneously while the correction is being performed. Performing two processing steps at the same time can effectively reduce the time cost required for the processing step, and the user can also save money on equipment.

[0040] In this embodiment, a limiting guide rail 10 is provided on the straightening bracket 1, an inclined surface is provided on the top of the limiting guide rail 10, an auxiliary pulley 36 is provided on the slide 31, and a conical surface rolling on the inclined surface is provided on the auxiliary pulley 36.

[0041] In this embodiment, a limiting elastic member 37 is provided on the auxiliary pulley 36 .

[0042] Through the above-mentioned design scheme, the inclined surface can enable the auxiliary pulley 36 to be stuck on the limiting guide rail 10, thereby preventing the slide 31 from shifting during straightening. At the same time, under the action of the limiting elastic member 37, the slide 31 can be stabilized in the middle position of the straightening bracket 1, ensuring that no shift will occur during the straightening and correction process.

[0043] In this embodiment, a balancing foot 5 is provided at the bottom of the straightening bracket 1 .

[0044] In this embodiment, a plurality of positioning components 4 are provided on the straightening bracket 1. The positioning components 4 include a transverse driving component 40, a lifting driving component 42 and a positioning block 41. The transverse driving component 40 is installed on the straightening bracket 1. The transverse driving component 40 is used to drive the lifting driving component 42 to move laterally. The lifting driving component 42 is used to drive the positioning block 41 to rise or fall.

[0045] Because when straightening work is being performed, the straightening machine is generally used with a transmission device, and the conveyor belt is used very frequently in the transmission device. The conveyor belt delivers the aluminum profile to be processed into the straightening range of the straightening machine. When loading, the transverse driving member 40 automatically adjusts the position of the positioning block 41 under the control of the system to ensure that the axis of the aluminum profile and the axis of the correction disk 22 are in the same vertical plane. When the conveyor belt is loading, the lifting driving member 42 drives the positioning block 41 to lift and block the aluminum profile to ensure that the correction work can be carried out accurately.

[0046] Compared with the prior art, the straightening machine provided by the utility model has the following advantages: when an aluminum profile has an abnormality and needs to be straightened, the transmission device transfers the aluminum profile to be processed to the top of the straightening bracket 1, and the positioning component 4 can make the axis of the lower aluminum profile and the axis of the correction disk 22 be in the same vertical plane, and then the straightening chuck 32 and the correction chuck 21 clamp the aluminum profile, and under the action of the lifting drive 33 and the sliding drive 23, the axis of the aluminum profile is lifted to coincide with the axis of the correction disk 22, and then the tensioning drive 30 drives the slide 31 to slide to tighten the aluminum profile, and then the correction disk 22 rotates, so that the aluminum profile is straightened and corrected at the same time.

[0047] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
