Technical Field

[0002] Square tube aluminum profiles refer to aluminum profiles with a square cross section. Square tube aluminum profiles used in the body frame of the automobile manufacturing field need to be flexible and elastic in order to absorb collision energy and protect the safety of passengers in the car. They can return to their original shape after being deformed by force. The body frame square tube aluminum profiles usually need to be customized according to the design requirements of specific models to adapt to the size and shape of different models, so the square tube aluminum profiles need to be cut and processed.

[0003] In the prior art, after the square tube aluminum profile is clamped and positioned by a positioning fixture, a saw blade is used to cut the aluminum profile in order to reduce the risk during operation and improve production efficiency to meet the needs of large-scale production.

[0004] However, since the square tube aluminum profile used in the body frame is flexible and elastic, when it is cut with a saw blade, the saw blade will exert an extrusion force on the aluminum profile in the initial cutting stage, causing a slight concave deformation at the cut of the aluminum profile, resulting in an uneven cut and insufficient processing accuracy, which is not conducive to subsequent welding and other processing of the aluminum profile.

DETAILED DESCRIPTION

[0041] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0042] In the body frame of the automobile manufacturing field (such as the square tube aluminum profile used in the RV compartment), in order to absorb collision energy and protect the safety of passengers in the car, the aluminum square tube profile needs to have the characteristics of flexibility and elasticity, and it can return to its original shape after being deformed by force. The square tube aluminum profile of the body frame usually needs to be customized according to the design requirements of the specific model to adapt to the size and shape of different models, so the square tube aluminum profile needs to be cut and processed. There are many ways to cut aluminum profiles, including laser cutting, saw cutting, plasma cutting, etc. Plasma cutting and laser cutting technology will cause the workpiece to generate higher temperatures locally during use, and the change of internal stress of the workpiece will easily cause deformation and distortion of the workpiece at the cutting point. In order to avoid such problems, saw cutting aluminum profiles is selected. Compared with plasma cutting and laser cutting technology, saw cutting has low equipment use cost and convenient maintenance, low technical requirements and easy operation, and fast cutting speed to meet the needs of large-scale production, so it is most appropriate to use saw cutting. In the prior art, after the workpiece is positioned, the saw blade is driven to rotate to cut the workpiece. However, since the square tube aluminum profile used in the body frame is flexible and elastic, when the saw blade is used to cut it, the saw blade will generate an extrusion force on the aluminum profile in the initial cutting stage, causing a slight concave deformation at the cut of the aluminum profile, resulting in an uneven cut of the aluminum profile and insufficient processing accuracy, which is not conducive to subsequent welding and other processing of the aluminum profile. If the cut is deeply ground, a lot of waste needs to be ground off to make the cut of the square tube aluminum profile smooth, resulting in the length of the cut square tube aluminum profile not meeting the design requirements. In order to solve the above problems, refer to the attached manual Figures 1 to 8 A high-precision aluminum profile cutting and processing device includes a cutting table 1, a lifting mechanism 2 is arranged on the cutting table 1, the lifting mechanism 2 includes a linear drive 21, a cutting mechanism 3 is arranged on the driving end of the linear drive 21, the cutting mechanism 3 includes a saw blade 31, and the linear drive 21 is used to drive the saw blade 31 to move vertically and horizontally;

[0043] A positioning assembly 4 is provided on the cutting table 1. The positioning assembly 4 includes two placement stations 41. The same workpiece is placed on the two placement stations 41. The two placement stations 41 position the workpiece horizontally by approaching each other.

[0044] A guide mechanism 6 is provided on the cutting table 1, and the guide mechanism 6 includes a guide wheel 61, and the guide wheel 61 positions the workpiece by fitting with the workpiece;

[0045] A cut correction mechanism 5 is also provided on the cutting table 1, and the cut correction mechanism 5 includes two correction seats 52. The correction seats 52 are located in the workpiece and fit against the inner wall of the workpiece. The saw blade 31 is located between the two correction seats 52. The distance between the two correction seats 52 on one side close to each other is the cutting area. The width of the cutting area is the same as the thickness of the saw blade 31. The saw blade 31 cuts the workpiece in the cutting area by rotating.

[0046] It should be noted that the workpiece is a square tube aluminum profile, and each surface of the correction seat 52 is in contact with the corresponding position of the inner wall of the workpiece, that is, after the correction seat 52 is inserted into the workpiece, the correction seat 52 and the vertical position of the workpiece are in a closed state. Before use, lubricant can be applied to the surface of the correction seat 52 to reduce the friction of the correction seat 52 sliding in the workpiece. A plurality of guide mechanisms 6 are provided, and the plurality of guide mechanisms 6 are symmetrically arranged in pairs.

[0047] The specific implementation scenario is as follows: the workpiece is placed on the placement station 41, the two placement stations 41 are driven to approach each other, the placement station 41 horizontally positions the two ends of the workpiece, and then the guide wheel 61 is driven to move toward the workpiece so that the guide wheel 61 contacts the workpiece, and the front and rear sides of the workpiece are horizontally positioned by the guide wheel 61, and then the correction seat 52 is extended into the workpiece through the end of the workpiece, so that the two correction seats 52 are close to each other, and when the two correction seats 52 are located at the specified position, the movement of the correction seats 52 is stopped. At this time, the gap between the sides of the two correction seats 52 that are close to each other is the cutting area, and the width of the cutting area is the same as the thickness of the saw blade 31, that is, the two correction seats 52 are close to each other. The distance between one side and the other side is the same as the thickness of the saw blade 31, and then the saw blade 31 is driven to move vertically downward by the linear drive 21, and the cutting area of ​​the workpiece is cut by the rotation of the saw blade 31. In the initial cutting stage, the saw blade 31 generates a downward extrusion force on the top of the workpiece. Since a correction seat 52 is provided in the workpiece, the correction seat 52 can support the inner wall of the workpiece to prevent the workpiece from being deformed due to the extrusion force, and the saw blade 31 cuts the workpiece in the cutting area, and the correction seat 52 stably supports the inner wall of the cutting port of the workpiece. Compared with the prior art, it can perform high-precision cutting on flexible and elastic square tube aluminum profiles, and the cutting port can remain flat.

[0048] When finely cutting a workpiece, a thinner or lower-quality saw blade 31 is selected. Thinner saw blades 31 can provide faster cutting speeds because they need to cut less material. However, since thinner or lower-quality saw blades 31 have weaker bending resistance when subjected to shear and pressure, the side of the saw blade 31 will produce certain vibrations during cutting. These vibrations are transmitted to the workpiece through the side of the saw blade 31, which may cause cracks or burrs in the material at the cut. When the saw blade 31 cuts the workpiece, as the feed depth of the saw blade 31 cutting the workpiece increases, the side of the correction seat 52 contacts the side of the saw blade 31, and the vibration generated when the saw blade 31 cuts the workpiece is reduced by adding restrictions on both sides of the saw blade 31.

[0049] Refer to the instruction manual Figures 1 to 8 When the saw blade 31 cuts the workpiece, the correction seat 52 contacts the side of the saw blade 31 to reduce the vibration of the saw blade 31, but the sliding friction between the saw blade 31 and the correction seat 52 is relatively large. In order to reduce the friction between the saw blade 31 and the correction seat 52, specifically, a groove 522 is provided on the correction seat 52, and a plurality of rolling balls 532 are rollingly arranged in the groove 522. The plurality of rolling balls 532 are arranged at equal intervals, and the rolling balls 532 are adapted to the saw blade 31.

[0050] It should be noted that during the process of cutting the workpiece, as the cutting feed depth of the saw blade 31 increases, the saw blade 31 contacts the ball 532, and the rotation of the saw blade 31 drives the ball 532 to roll. Most of the area on the contact side of the correction seat 52 and the saw blade 31 changes from sliding friction to rolling friction. The ball 532 can not only support the two sides of the saw blade 31, but also effectively reduce the friction between the saw blade 31 and the correction seat 52, and reduce the heat generated by friction.

[0051] Refer to the instruction manual Fig. 9 and Fig.10 In the process of the saw blade 31 cutting the workpiece, in order to actively cool the saw blade 31 and maintain the cutting performance of the saw blade 31, specifically, a storage cavity 521 is opened in the correction seat 52, and a coolant is arranged in the storage cavity 521. A piston plate 53 is slidably arranged in the storage cavity 521, and an elastic member 531 is arranged between the piston plate 53 and the inner wall of the storage cavity 521. A connecting pipe 533 is fixedly arranged on the inner wall of the storage cavity 521, and the connecting pipe 533 is in contact with the ball 532.

[0052] It should be noted that the elastic member 531 is configured as a spring, which is fixed to the piston plate 53. One end of the spring away from the piston plate 53 is fixed to the inner wall of the storage cavity 521. A pull rod is fixed on the piston plate 53, and the pull rod is slidably arranged with the correction seat 52. A feed pipe is fixedly connected in the storage cavity 521, and the feed pipe is used to add coolant to the correction seat 52. One end of the connecting pipe 533 facing the ball 532 fits with the corresponding ball 532.

[0053] It should also be noted that coolant is injected into the storage cavity 521 through the feed pipe, and the piston plate 53 is always pushed to move toward the connecting tube 533 under the action of the elastic force of the elastic member 531. The coolant in the storage cavity 521 can always fill the connecting tube 533, and the ball 532 blocks the connecting tube 533 to prevent the coolant in the storage cavity 521 from being directly discharged through the connecting tube 533, and the coolant adheres to the ball 532. During the process of the saw blade 31 cutting the workpiece, the ball 532 is driven to rotate, and the ball 532 and the saw blade 31 are in rolling contact. The ball 532 coats the coolant on its surface on the saw blade 31. After the surface of the saw blade 31 is coated with coolant, it has a cooling effect, thereby achieving the effect of actively cooling the saw blade 31.

[0054] Refer to the instruction manual Figures 1 to 3In order to facilitate the adjustment of the movement of the saw blade 31 and cut the workpiece through the saw blade 31, specifically, the lifting mechanism 2 includes a sliding seat 22, the sliding seat 22 is slidably set on the driving end of the linear driver 21, a rotating driver 23 is fixedly set on the driving end of the linear driver 21, a gear is fixedly set on the output shaft of the rotating driver 23, a rack 24 is fixedly set on the sliding seat 22, and the gear is meshed with the rack 24.

The gear engages with the rack 24 to drive the sliding seat 22 to move horizontally.

[0058] It should be noted that the support frame 32 is configured as a motor, the motor is rotatably arranged on the support frame 32 , the saw blade 31 is fixedly arranged on the output shaft of the motor, and the rotation driver three 34 is configured as a motor, which is fixedly arranged on the support frame 32 .

[0059] It should also be noted that when the workpiece is cut at an angle, that is, the workpiece is cut in an inclined state, the rotation of the output shaft of the rotary driver 2 33 drives the saw blade 31 to rotate. When the angle between the saw blade 31 and the workpiece needs to be adjusted, the rotary driver 34 is started, and the rotation of the output shaft of the rotary driver 34 drives the bevel gear 1 to engage with the bevel gear 2 to achieve the effect of adjusting the angle of the saw blade 31. When the inclination angle of the saw blade 31 is adjusted, the workpiece is driven to move toward the saw blade 31 to cut the bevel of the workpiece.

[0060] Refer to the instruction manual Figures 1 to 4In order to facilitate the positioning of the workpiece and ensure the cutting accuracy, specifically, the positioning component 4 includes a base 43, the base 43 is fixedly arranged on the cutting table 1, a rotating driver 44 is fixedly arranged on the base 43, a screw 45 is fixedly arranged on the output shaft of the rotating driver 44, the screw 45 is rotatably arranged with the base 43, the placement station 41 is threadedly connected with the screw 45, a connecting plate 42 is fixedly arranged on the placement station 41, a through hole 421 is opened on the connecting plate 42, a linear driver 46 is fixedly arranged on the connecting plate 42, and a positioning seat 47 is fixedly arranged on the output shaft of the linear driver 46.

[0062] It should also be noted that the connecting plate 42 is fixed on the placement station 41 by bolts, the length and width of the inner wall of the through hole 421 are greater than the length and width of the correction seat 52, and the length and width of the inner wall of the through hole 421 are less than the length and width of the workpiece, that is, the correction seat 52 can pass through the through hole 421, and after the connecting plate 42 contacts the end of the workpiece, the two connecting plates 42 are driven close to each other to position the two ends of the workpiece. A visual recognition instrument is set on the cutting table 1, which recognizes the length of the workpiece, and then obtains the cutting position of the workpiece according to the use requirements. The movement of the placement station 41 is used to adjust the cutting position of the workpiece.

[0063] In this embodiment, the workpiece is placed on the placement station 41, and the rotating driver four 44 is started. The rotation of the output shaft of the rotating driver four 44 drives the screw rod one 45 to rotate, and the rotation of the screw rod one 45 drives the placement station 41 to move. The two placement stations 41 are close to each other to position the two ends of the workpiece, and the linear driver two 46 is started. The movement of the output shaft of the linear driver two 46 drives the positioning seat 47 to apply downward pressure on the top of the workpiece, that is, the workpiece is positioned in the vertical direction, and the length of the base one 43 is set to be longer. After the placement station 41 cooperates with the positioning seat 47 to position the workpiece, the cutting position of the workpiece can be adjusted by the synchronous movement of the two placement stations 41.

[0064] Refer to the instruction manual Figures 1 to 5 After the workpiece is positioned, in order to facilitate driving the correction seat 52 to move into the workpiece, specifically, the incision correction mechanism 5 includes two linear drivers 51, the linear drivers 51 are fixedly set on the cutting table 1, the correction seat 52 and the output shaft of the linear drivers 51 are fixedly set, and the two linear drivers 51 are symmetrically set.

[0065] It should be noted that the linear drive 3 51 is configured as a cylinder, the cylinder is fixedly disposed on the cutting table 1 , the correction seat 52 is fixedly disposed on the output end of the cylinder by bolts, and the two cylinders are symmetrically disposed on the cutting table 1 .

[0066] It should also be noted that after the workpiece is positioned by the placement station 41, the linear drive three 51 is started, and the movement of the output shaft of the linear drive three 51 drives the correction seat 52 to move into the workpiece. The correction seat 52 supports the inner wall of the workpiece. When the size of the workpiece changes, the correction seat 52 can be replaced to meet the support requirements of workpieces of different sizes.

[0067] Refer to the instruction manual Figures 1 to 6 When the placement station 41 drives the workpiece to move, in order to prevent the workpiece from being offset, the movement of the workpiece is guided, and the front side of the workpiece placement station 41 can be driven to move horizontally. Specifically, the guide mechanism 6 includes a base 62, and the base 62 is fixedly set on the cutting table 1. A rotating driver 5 63 is fixedly set on the base 62. A screw 2 64 is fixedly set on the output shaft of the rotating driver 5 63. The screw 2 64 is rotatably set with the base 62, and a moving seat 65 is threadedly connected to the screw 2 64.

[0069] It should also be noted that, when the rotary driver 5 63 is started, the rotation of the output shaft of the rotary driver 5 63 drives the screw rod 2 64 to rotate, and the rotation of the screw rod 2 64 drives the moving seat 65 to move. When the guide wheel 61 is in contact with the surface of the workpiece, the front and rear side movement of the workpiece can be limited. When the two placement stations 41 move synchronously to adjust the cutting position of the workpiece, the guide wheel 61 can guide and limit the movement of the workpiece. A set of linear drivers 2 46 can also be set on the moving seat 65, so that the linear driver 2 46 is located above the moving seat 65, and the output end of the linear driver 2 46 is used to limit the top of the workpiece, and to perform multi-point limiting on the workpiece. When the workpiece needs to be cut at an angle, first adjust the state of the saw blade 31 so that the saw blade 31 is set to an inclined setting, and then drive the horizontal movement of the front and rear sides of the workpiece by the guide wheel 61, so that the workpiece can be cut at an angle.

[0070] Refer to the instruction manual Figure 1 , Figure 2 and Fig.11The hardness of aluminum profiles is different, and the requirements for saw blades are also different. Harder materials require thicker saw blades 31 to prevent bending or breaking during the cutting process. When cutting thicker aluminum profiles, thicker saw blades 31 are also required to ensure the stability and accuracy of cutting. Therefore, it is necessary to replace saw blades 31 of different thicknesses according to cutting requirements. If the saw blade 31 is replaced, due to the different thicknesses of the saw blade 31, the support of the workpiece also needs to be adjusted relatively. The gap at the support for placing the saw blade 31 needs to be adjusted according to the thickness of the saw blade 31. Specifically, an installation groove is provided on the cutting table 1, and a support seat 7 is fixedly arranged in the installation groove, and a blanking hole 71 is provided on it. The workpiece is matched with the top of the support seat 7, and the blanking hole 71 is matched with the saw blade 31.

[0071] It should be noted that the support seat 7 is fixed in the mounting groove by bolts, and the sizes of the blanking holes 71 opened on the multiple support seats 7 are different.

A nozzle is fixedly connected to the inner wall of the blanking hole 71, and a fan is fixedly connected to the end of the nozzle away from the support seat 7. When the saw blade 31 cuts the workpiece and is located in the blanking hole 71, the nozzle sprays airflow toward the saw blade 31 for actively dissipating heat and cooling the saw blade 31.

[0072] It should also be noted that, when the saw blade 31 of different thickness is replaced, the corresponding support seat 7 can be replaced according to the thickness of the saw blade 31 .
