Description

[0002] In modern industrial production, profiles are an extremely important basic material, widely used in many fields such as construction, machinery manufacturing, automobile industry, aerospace, etc. Profiles are usually made by extrusion, rolling, forging and other processes. During these processes, due to the influence of various factors, such as extrusion speed, raw material thickness, rolling fluctuations and forging temperature, profiles often have deformation defects such as bending and twisting to varying degrees.

[0003] In addition, during the subsequent handling, storage and processing, the profiles may also be deformed due to external impact, unreasonable stacking, etc. If these deformations are not corrected, they will seriously affect the performance of the profiles and product quality.

[0004] In the related art, the profile is generally straightened with the aid of mechanical equipment (for example, a press) by applying a force to the highest point of the bent portion of the profile to force the portion to deform. Due to the existence of internal stress in some profiles, the single deformation of the profile during the straightening process is large, and the profile is easy to recover after one straightening. Relevant technicians need to apply force to the portion multiple times or continuously for straightening. This not only leads to low work efficiency, but also makes the surface of the profile prone to cracks or even tears, thereby reducing the yield of the profile. Summary of the invention

[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The profile straightening device of an embodiment of the present application is described below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 7 As shown, the profile straightening device of the embodiment of the present application may include: a main body component 1, a positioning mechanism 2, two straightening mechanisms 3, a driving mechanism 4 and a controller 5.

[0030] The main body component 1 is placed vertically relative to the ground.

[0031] It should be noted that a plurality of legs are provided at the bottom of the main component 1 described in this embodiment, and the legs can reduce the contact area between the device and the ground, increase the pressure between the two, and increase the stability of the device during use.

[0032] The positioning mechanism 2 includes an auxiliary component 21 and a clamping component 22, wherein the auxiliary component 21 is arranged on the main component 1, the auxiliary component 21 is used to support the bottom of the profile to be processed, the clamping component 22 is connected to the auxiliary component 21, and the clamping component 22 is used to apply force to the upper side of the profile to be processed, which can play a role of fixing and limiting.

[0033] The driving mechanism 4 is installed on the main assembly 1 , and is used to drive the two straightening mechanisms 3 to move toward or away from each other.

[0034] The two straightening mechanisms 3 are arranged symmetrically, and the straightening mechanism 3 includes a frame 31 , two first driving assemblies 32 and a first roller 33 .

[0035] The frame 31 is connected to the driving mechanism 4 , two first driving components 32 are symmetrically mounted on the frame 31 , and the first roller 33 is rotatably disposed between the two first driving components 32 .

[0036] The controller 5 is installed on the main assembly 1 , and the clamping assembly 22 , the first driving assembly 32 and the driving mechanism 4 are respectively connected to the controller 5 .

[0037] In the embodiment of the present application, the external mains power is used to power the positioning mechanism 2, the straightening mechanism 3, the driving mechanism 4 and the controller 5 in the device, thereby ensuring the normal operation of the device.

[0038] Specifically, during the transportation of profiles (such as aluminum profiles), due to the action of external forces, or during the production of profiles, due to process limitations, the profiles may bend and deform. Relevant technicians use this equipment to straighten the profiles.

[0039] First, the two straightening mechanisms 3 are placed in the initial position, that is, the two straightening mechanisms 3 are close to the positioning mechanism 2. The relevant technical personnel determine the part of the profile to be straightened, and pass the end of the profile through one straightening mechanism 3, the positioning mechanism 2 and the inside of another straightening mechanism 3 in turn. The protruding part of the part of the profile to be straightened is placed between the auxiliary component 21 and the clamping component 22. At this time, the protruding part faces the ground, and the two ends of the profile are raised.

[0040] The clamping assembly 22 applies a first preset force to the protruding portion, thereby fixing the profile on the device. At this time, relevant technicians can stay away from the device to ensure safety during the profile processing.

[0041] Next, the straightening mechanism 3 starts to operate. According to the first preset force, the first driving component 32 drives the first roller 33 downward, and the first roller 33 contacts the outer wall of the profile. Under the action of the first driving component 32, the first roller 33 applies a second force equal to the first preset force to the profile.

[0042] Then, under the action of the driving mechanism 4, the two straightening mechanisms 3 move in opposite directions, and the force between the first roller 33 and the profile gradually increases. The straightening mechanism 3 passes through the edge of the curved part of the profile, and then reaches the highest point of the curved part. The profile is straightened by continuously increasing the force, thereby weakening the recovery amount of the profile after straightening, improving work efficiency, and avoiding excessive deformation of the profile during straightening, which leads to cracks and tears on the surface of the profile, thereby ensuring the yield of the profile.

[0043] If there are other locations on the profile that need to be straightened, repeat the above operation for processing.

[0044] It should be noted that during the straightening process of the profile, except for the position of the positioning mechanism 2, the lower part of the profile is in a suspended state. Relevant technical personnel can increase the second force, that is, the first drive component 32 drives the first roller 33 to apply a greater force to the profile, so that the profile is over-straightened, the recovery amount of the profile after straightening is weakened, and the work efficiency is improved.

[0045] As a possible situation, in order to prevent the bent portion of the profile from recovering, the driving mechanism 4 can drive the two straightening mechanisms 3 to move back and forth on the surface of the profile for multiple times.

[0046] Finally, after the straightening of the profile is completed, the straightening mechanism 3 is reset, and the relevant technician holds one end of the profile, the positioning mechanism 2 is reset, and then the profile is pulled to remove it from the equipment.

[0047] In one embodiment of the present application, Figure 1 As shown, the main body component 1 includes a first support frame 11 , a first vertical plate 12 , two second vertical plates 13 and a second support frame 14 .

[0048] Among them, the first vertical plate 12 is connected to the first support frame 11, the first vertical plate 12 is located in the middle of the first support frame 11, the two second vertical plates 13 are symmetrically arranged on the first support frame 11, the second vertical plates 13 are located at the end of the first support frame 11, the second support frame 14 is connected to the first vertical plate 12 and the two second vertical plates 13, and the first vertical plate 12, the two second vertical plates 13 and the second support frame 14 are respectively rotatably connected to the driving mechanism 4.

[0049] It should be noted that the second support frame 14 described in this embodiment is provided with two symmetrically arranged through slots, so as to avoid the end of the profile being restricted during straightening and ensure the smooth straightening process of the profile.

[0050] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the auxiliary component 21 includes two support plates 211 , a second roller shaft 212 and two fixing ear plates 213 .

[0051] The two support plates 211 are symmetrically arranged on the second support frame 14 , the second roller 212 is rotatably connected between the two support plates 211 , the two fixed ear plates 213 are respectively installed on the corresponding support plates 211 , and the fixed ear plates 213 are rotatably connected to the driving mechanism 4 .

[0052] It is understandable that when relevant technicians place the profile on the positioning mechanism 2, the second roller 212 rotates, which can reduce the friction between the positioning mechanism 2 and the profile, making the use of the device more labor-saving.

[0053] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the clamping assembly 22 includes two support frames 221 , two second driving assemblies 222 and a third roller shaft 223 .

[0054] The two support frames 221 are respectively connected to the corresponding support plates 211 , the two second driving components 222 are respectively installed on the corresponding support frames 221 , and the third roller 223 is rotatably disposed between the two second driving components 222 .

[0055] It should be noted that the specific structure of the second driving assembly 222 described in this embodiment is the same as the specific structure of the first driving assembly 32 .

[0056] In one embodiment of the present application, Figure 1 , Figure 3 and Figure 4 As shown, the driving mechanism 4 includes two second screw rods 41 , two third screw rods 42 , a plurality of driven sprocket wheels 43 , a transmission chain 44 , a driving sprocket wheel 45 and a second driving device 46 .

[0057] Among them, the two ends of the two second screws 41 and the two third screws 42 are respectively rotatably connected to the corresponding second vertical plates 13, the two second screws 41 are rotatably connected to the first vertical plate 12, the two third screws 42 are rotatably connected to the fixed ear plate 213, the two second screws 41 and the two third screws 42 are respectively threadedly connected to the frame 31, a plurality of driven sprockets 43 are respectively arranged at one end of the two second screws 41 and the two third screws 42, a second driving device 46 is installed on a second vertical plate 13, the output shaft of the second driving device 46 is connected to the driving sprocket 45, and the transmission chain 44 is wound around the outside of the plurality of driven sprockets 43 and the driving sprocket 45.

[0058] In one embodiment of the present application, Figure 1 and Figure 5 As shown, the first driving assembly 32 includes a first screw rod 321 , a first driving device 322 , a connecting frame 323 , a connecting block 324 , a plurality of guide rods 325 and a patch pressure sensor 326 .

[0059] Among them, the first screw 321 is rotationally connected to the frame 31, the first driving device 322 is installed on the frame 31, the output shaft of the first driving device 322 is connected to one end of the first screw 321, the connecting frame 323 is threadedly connected to the first screw 321, the connecting block 324 is placed inside the connecting frame 323, a plurality of guide rods 325 are connected to the connecting block 324, the guide rods 325 are slidingly connected to the connecting frame 323, the patch pressure sensor 326 is installed on the inner wall of the connecting frame 323, and the patch pressure sensor 326 is connected to the controller 5.

[0060] It should be noted that the patch pressure sensor 326 described in this embodiment is connected to the controller 5 .

[0061] Specifically, the profile to be straightened is placed between the second roller 212 and the third roller 223, and then the first drive assembly 32 drives the first roller 33 to contact the profile, and the first drive device 322 drives the first screw 321 to rotate, and the first screw 321 is threadedly connected to the connecting frame 323, and the connecting frame 323 drives the connecting block 324 to move, and the connecting block 324 drives the first roller 33 to move, and the first roller 33 applies a force to the profile, and the profile applies a reaction force to the first roller 33, and the guide rod 325 plays a guiding role. The patch pressure sensor 326 is squeezed by the connecting block 324 to measure this force and transmit the pressure data to the controller 5.

[0062] Under the action of the driving mechanism 4, the second driving device 46 operates, and the second driving device 46 drives the active sprocket 45 to rotate. Under the action of the transmission chain 44, multiple driven sprockets 43 rotate, the two second screws 41 and the two third screws 42 rotate, and the two straightening mechanisms 3 move. The first roller 33 interacts with the profile, and the profile is compressed and deformed, thereby achieving a straightening effect.

[0063] In one embodiment of the present application, Figure 1 and Figure 6 As shown, two heating mechanisms 6 are also included. The two heating mechanisms 6 are respectively installed on the corresponding straightening mechanisms 3. The heating mechanisms 6 include a ring body 61, a plurality of connecting parts 62 and a heating coil 63.

[0064] The ring body 61 is disposed on the frame body 31 , and the heating coil 63 is installed inside the ring body 61 through a plurality of connectors 62 .

[0065] It should be noted that the specific working principle of the heating coil 63 described in this embodiment has been disclosed in the prior art, so it will not be described in detail here.

[0066] It can be understood that the heating mechanism 6 can be provided to heat the profile during the profile straightening process, thereby facilitating the deformation of the profile.

[0067] In one embodiment of the present application, Figure 1 and Figure 7 As shown, a groove 71 is formed on the other second vertical plate 13 , and an auxiliary roller 72 is rotatably connected inside the groove 71 .

[0068] It is understandable that the provision of the auxiliary roller 72 can reduce the friction between the profile and the device when the relevant technicians place the profile inside the device, thereby facilitating the use of the device.

[0069] In summary, the profile straightening equipment of the embodiment of the present application uses a positioning mechanism to fix the middle part of the profile. Under the action of the driving mechanism, the two straightening mechanisms move opposite to each other on the profile. During the process, the straightening mechanism passes through the edge of the curved part of the profile, and then reaches the highest point of the curved part. The profile is straightened by continuously increasing the force. At the same time, the first driving component can be used to change the position of the first roller in the frame. Through over-straightening, the recovery amount of the profile after straightening is weakened, thereby improving work efficiency and avoiding excessive deformation of the profile during straightening, which leads to cracks and tears on the surface of the profile, thereby ensuring the yield of the profile.
