Description

Technical Field

[0001] The invention relates to the technical field of bending and forming, and in particular to bending and forming equipment for aluminum product processing based on CNC machine tools. Background Art

[0002] Aluminum products are a general term for daily necessities and industrial products made of aluminum alloy as the main raw material. Aluminum alloy is a general term for alloys based on aluminum. Aluminum alloy has low density but relatively high strength, close to or exceeding that of high-quality steel. It has good plasticity and can be processed into various profiles. Therefore, it is widely used in various industries. Aluminum tubes are a more common type of aluminum products. In order to meet the needs of use, they will be bent during the processing of aluminum tubes according to actual conditions. Therefore, a bending device is needed to place the aluminum tube on the bending device and bend it through the bending device. However, the current bending device has a relatively simple structure, and each part is fixed and cannot be adjusted. The functionality is poor and cannot meet the current use needs.

[0003] For example, in the prior art, there is a CNC aluminum product bending and forming device with a publication number of CN110587312A. Although the bending and forming device can realize the integrated processing of forming and bending of aluminum tubes, the following problems still exist during the processing:

[0004] (1) In the forming stage, the aluminum tube is extruded and formed only once through multiple forming wheels. This forming method is often difficult to better release the stress generated by the aluminum tube during the deformation process. The concentration and residual stress can easily lead to cracks on the surface or inside of the formed aluminum tube, which not only affects the appearance quality of the aluminum tube, but also reduces the strength and durability of its structure.

[0005] (2) During the bending stage, processing of multiple bending angles can only be achieved in the horizontal direction. However, as the bending requirements of aluminum products in modern industry become increasingly diversified, multiple bending angles in different directions are usually required. This device limits the flexibility of the bending range and is difficult to meet complex and changing processing requirements.

[0006] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0007] The purpose of the present invention is to provide a bending and forming equipment for aluminum product processing based on CNC machine tools to solve the technical defects mentioned above.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1-Figure 6As shown, in the prior art, the problem that the quality of the formed aluminum tube is easily reduced by only extruding the aluminum tube once through multiple forming wheels can be solved by the following solution:

[0043] In this embodiment, the bending and forming equipment for aluminum product processing based on CNC machine tool processing includes a base 1, a mounting sleeve 11 and a control console 12 are fixedly installed on the top of the base 1, and a controller in the control console 12 is used to control the operation of each driving member, so as to realize the precise CNC processing of the aluminum product, i.e., the aluminum tube, and a plurality of clamping forming components 2 are installed inside the mounting sleeve 11, and the clamping forming components 2 include a fixing seat 21, and an extrusion seat 22 is installed inside the fixing seat 21;

[0044] The extrusion seat 22 is detachably connected with a forming block 23, and an adapted forming block 23 can be replaced according to the processing requirements of the aluminum tube, and the cross section of the forming block 23 is a trapezoidal structure, so that the forming block 23 can form a step-by-step extrusion forming effect on the aluminum tube during the movement of the forming block 23 close to the adaptive bending component 4. The extrusion seat 22 carries the forming block 23 to rotate in a similar elliptical path in the fixed seat 21, so that multiple forming blocks 23 are forced to extrude the aluminum tube multiple times and intermittently, which can not only improve the stress release during the deformation process of the aluminum tube;

[0045] It can also improve the smoothness of the aluminum tube surface after extrusion. In addition, the aluminum tube is simultaneously pushed to move a short distance during the extrusion process, and the inclined extrusion side on the forming block 23 is cooperated to form a multiple step-by-step extrusion molding effect on the aluminum tube. Compared with the one-time extrusion molding method in the prior art, it can effectively improve the quality and effect of the aluminum tube after molding, and avoid the problem of excessive deformation and easy cracking caused by a single extrusion molding.

[0046] A rotating assembly 3 is provided on one side of the top of the base 1. The rotating assembly 3 includes an annular fixing plate 31 fixedly connected to the top of the base 1, and a rotating mounting ring 32 is rotatably mounted on the annular fixing plate 31.

[0047] An adaptive bending assembly 4 is provided on the rotating mounting ring 32. The adaptive bending assembly 4 includes a mounting platform 41 bolted to the rotating mounting ring 32, and a fixing column 42 is rotatably mounted on the mounting platform 41. A bending rod 44 is connected to the fixing column 42 via a rotating plate 43. The rotating plate 43 and the bending rod 44 can be driven to perform circumferential movement by the rotation of the fixing column 42, thereby completing the bending process of the formed aluminum tube.

[0048] The rotating plate 43 is fixedly connected to the bottom of one side of the fixed column 42, the bending rod 44 is threadedly connected to the rotating plate 43, and a plurality of threaded holes are equidistantly provided on the rotating plate 43 for adjusting the distance between the bending rod 44 and the fixed column 42, thereby achieving the effect of adjusting the arc of the bending angle of the formed aluminum tube. Centering and anti-slip components 5 that cooperate with the clamping forming component 2 are provided on both sides of the mounting sleeve 11 for centering and auxiliary clamping of the aluminum tube.

[0049] A plurality of ear blocks 24 are equidistantly fixedly connected to one side of the extrusion seat 22, and a connecting plate 25 is rotatably connected to the ear block 24, and an orbiting plate 26 and a swinging plate 27 are rotatably connected to the two ends of the connecting plate 25, respectively, and a rotating rod rotatably connected to the fixed seat 21 is fixedly connected to the orbiting plate 26 and the swinging plate 27, and a worm gear 28 is fixedly connected to the rotating rod connected to the orbiting plate 26. When the orbiting plate 26 rotates, the orbiting plate 26 combines with the swinging plate 27 to drive the connecting plate 25 to swing, and the connecting plate 25 combines with the ear block 24 to force the extrusion seat 22 to rotate along an elliptical path.

[0050] The fixed seat 21 is internally rotatably connected with a rotating rod 29, and the rotating rod 29 is fixedly connected with a worm 210 meshing with the corresponding worm wheel 28. The fixed seat 21 is bolted with a servo motor 211 for driving the rotating rod 29 to rotate. The controller inside the control console 12 controls the servo motors 211 on multiple fixed seats 21 to rotate synchronously, and the servo motors 211 drive the corresponding rotating rods 29 to rotate. The rotating rods 29 drive the orbiting plate 26 to rotate through the meshing worm 210 and the worm wheel 28.

[0051] In addition, with the help of self-locking between the worm 210 and the worm wheel 28, auxiliary clamping is performed during the bending process of the formed aluminum tube to avoid stress on the aluminum tube during bending, promote the separation of the aluminum tube and the forming block 23, and then improve the stability of the aluminum tube during the bending process.

[0052] A sliding rod slidably connected to the mounting sleeve 11 is symmetrically fixed on one side of the fixing seat 21, which is used to increase the stability of the sliding connection between the fixing seat 21 and the mounting sleeve 11. An electric push rod 212 is bolted to the outer wall of the mounting sleeve 11, and the piston rod end of the electric push rod 212 is fixedly connected to the corresponding fixing seat 21. The electric push rod 212 is controlled by a controller inside the console 12 to drive the corresponding fixing seat 21 to move, and the positions of the multiple forming blocks 23 can be adjusted according to the size of the aluminum tube, thereby adjusting the size of the aluminum tube after forming.

[0053] A connecting block 213 is fixedly connected to the extrusion seat 22, and a connecting hole is penetrated through the connecting block 213. A connecting groove matched with the connecting block 213 is opened on the forming block 23. A threaded rod 214 matched with the connecting hole is threadedly connected to the forming block 23. By rotating the threaded rod 214 to separate it from the connecting block 213, the forming blocks 23 of different shapes on the extrusion side can be replaced to complete the extrusion molding of different shapes of the aluminum tube.

[0054] The centering anti-slip assembly 5 includes a rotating ring 51 rotatably connected to the outside of the mounting sleeve 11, and one side of the rotating ring 51 is fixedly connected to multiple groups of rotating blocks 52, and the multiple groups of rotating blocks 52 are distributed in a ring array relative to the axis of the rotating ring 51, and the inside of the rotating block 52 is rotatably installed with a clamping rod 54 through a ratchet 53, and the free end of the clamping rod 54 is slidably connected to a rotating block 2 55 rotatably connected to the mounting sleeve 11, and the outer fixed sleeve of the clamping rod 54 is provided with an anti-slip sleeve 56, which can increase the anti-slip effect between the clamping rod 54 and the aluminum tube, thereby realizing the reverse return restriction of the aluminum tube after clamping and fixing, and a cylinder 57 is hinged between the rotating ring 51 and the base 1;

[0055] The centering and anti-slipping component 5 can not only perform centering and auxiliary clamping on aluminum tubes of different sizes during the extrusion molding process to ensure the effective mobile molding process of the aluminum tube by the clamping molding component 2, but also can be combined with the clamping molding component 2 to enhance the centering and clamping effect of the aluminum tube during the bending process, and solve the problem of aluminum tube displacement resulting in inaccurate bending points;

[0056] One end of the aluminum tube is passed through the multiple groups of clamping rods 54 on one side of the installation sleeve 11 to the inside of the installation sleeve 11, and the controller inside the control console 12 controls the piston rod of the cylinder 57 on one side to extend and retract, driving the corresponding rotating ring 51 to rotate, forcing the multiple groups of clamping rods 54 to center the aluminum tube, and with the cooperation of the ratchet 53, the clamping rods 54 are limited to unidirectional rotation to prevent the aluminum tube from being pulled out. After the formed end of the aluminum tube passes through the installation sleeve 11, the controller inside the control console 12 controls the piston rod of the cylinder 57 on the other side to extend and retract, driving the corresponding rotating ring 51 to rotate, forcing the remaining multiple groups of clamping rods 54 to center the aluminum tube on the other side of the installation sleeve 11.

[0057] Example 2: Please refer to Figure 7-Figure 9 As shown, the problem that the aluminum tube cannot be bent at multiple and different bending angles can be solved by the following solutions:

[0058] In this embodiment, one side of the annular fixing plate 31 is fixedly connected to an annular slide rail 33 that is slidably connected to the rotating mounting ring 32, thereby increasing the stability of the rotating mounting ring 32 during rotation. An outer toothed ring 34 is fixedly connected to the annular outer wall of the rotating mounting ring 32. A servo motor 35 is bolted to the annular fixing plate 31, and a gear 36 meshing with the outer toothed ring 34 is fixedly connected to the output shaft of the servo motor 35. The controller in the control console 12 controls the servo motor 35 to drive the gear 36 to rotate, and the rotating mounting ring 32 is driven to rotate through the meshing of the gear 36 and the outer toothed ring 34, thereby adjusting the angle of the mounting platform 41, thereby realizing the bending processing of multiple and different bending angles of the aluminum tube.

[0059] A movable plate 45 is provided on the mounting platform 41, and two sets of guide rods slidably connected to the mounting platform 41 are fixedly connected to the movable plate 45, which are used to adjust the position of the fixed column 42 according to aluminum tubes of different sizes. The guide rods are provided to improve the stability of the movable plate 45 during movement. An annular slide rail 46 slidably connected to the fixed column 42 is fixedly connected to the movable plate 45, thereby increasing the stability of the fixed column 42 during rotation.

[0060] A second electric push rod 47 is bolted on one side of the mounting platform 41 away from the movable plate 45, and the piston rod of the second electric push rod 47 movably penetrates into the interior of the fixed column 42 and is fixedly connected to a push block 48, and guide pins 49 are symmetrically fixedly connected to both sides of the push block 48, and an oblique guide groove 410 slidably connected to the corresponding guide pin 49 is opened on the inner wall of the fixed column 42;

[0061] After the formed end of the aluminum tube passes through the rotating plate 43 and the bending point of the aluminum tube is located at the position of the fixed column 42, the continuous extrusion molding of the aluminum tube is stopped, and the aluminum tube is stably clamped by the multiple forming blocks 23 against the aluminum tube and the clamping rod 54 limiting the reverse return of the aluminum tube. The controller inside the control console 12 controls the piston rod of the electric push rod 2 47 to extend. When the fixed column 42 is restricted to move continuously away from the mounting platform 41, the push block 48 compresses the spring 412 to move continuously, and with the help of the guide pin 49 sliding in the corresponding oblique guide groove 410, the fixed column 42 is forced to rotate in combination with the rotating plate 43 to drive the bending rod 44 to rotate, thereby bending the formed aluminum tube.

[0062] A plurality of bent retaining grooves 411 distributed in a stepped manner are provided on the annular outer wall of the fixed column 42. A spring 412 is fixedly connected between the push block 48 and the top of the fixed column 42. After the piston rod of the electric push rod 47 is extended, the spring 412 cooperates with the push block 48 to drive the fixed column 42 to move close to the molded aluminum tube. Through the plurality of bent retaining grooves 411 distributed in a stepped manner, the fixed column 42 is prompted to adaptively contact the bent sides of molded aluminum tubes of different sizes.

[0063] When a bending stop groove 411 on the outer wall of the fixing column 42 contacts the aluminum tube, the bending between the fixing column 42 and the mounting sleeve 11 can be avoided during the bending process, and the continuous movement of the fixing column 42 is limited. The push block 48 compresses the spring 412 to continue to move, and guides the guide pin 49 through the oblique guide groove 410, forcing the fixing column 42 to rotate, and also twists the spring 412, so that the spring 412 generates an elastic force for twisting and restoring.

[0064] After the bending is completed, the electric push rod 47 drives the fixed column 42 to move towards the mounting platform 41. Under the torsional elastic force of the spring 412, the bending rod 44 is forced to separate from the aluminum tube, and then the movable plate 45 contacts the mounting platform 41 to ensure the effective resetting of the bending rod 44 and maintain the resetting state.

[0065] Example 3: Please refer to Figure 1-Figure 9 As shown, the present invention also proposes a method for using a bending and forming device for aluminum product processing based on CNC machine tools, comprising the following steps:

[0066] Step 1: Pass one end of the aluminum tube through the multiple groups of clamping rods 54 on one side of the installation sleeve 11 and into the interior of the installation sleeve 11. The piston rod of the cylinder 57 on one side is controlled by the controller inside the console 12 to extend and retract, driving the corresponding rotating ring 51 to rotate, forcing the multiple groups of clamping rods 54 to center the aluminum tube, and with the cooperation of the ratchet 53, limiting the one-way rotation of the clamping rods 54 to prevent the aluminum tube from being pulled out;

[0067] Step 2: The controller inside the console 12 controls the servo motors 211 on the multiple fixed seats 21 to rotate synchronously, and the servo motors 211 drive the corresponding rotating rods 29 to rotate. The rotating rods 29 drive the orbiting plate 26 to rotate through the meshing worm 210 and the worm wheel 28. The orbiting plate 26 is combined with the swing plate 27 and the connecting plate 25 to force the extrusion seat 22 to rotate along an elliptical path, thereby prompting the multiple forming blocks 23 to intermittently extrude the aluminum tube, and at the same time, intermittently push the aluminum tube to move a short distance, and cooperate with the inclined extrusion side on the forming block 23 to perform step-by-step extrusion molding on the aluminum tube to improve the molding quality and effect;

[0068] Step 3: By controlling the electric push rod 212 to drive the corresponding fixing seat 21 to move, the positions of the plurality of forming blocks 23 are adjusted according to the size of the aluminum tube, and then the size of the aluminum tube after forming is adjusted. By rotating the threaded rod 214 to separate it from the connecting block 213, the forming blocks 23 of different shapes on the extrusion side can be replaced, and the aluminum tube can be extruded into different shapes;

[0069] Step 4: After the formed end of the aluminum tube passes through the installation sleeve 11, the controller inside the control console 12 controls the piston rod of the cylinder 57 on the other side to extend and retract, driving the corresponding rotating ring 51 to rotate, forcing the remaining multiple groups of clamping rods 54 to center and clamp the aluminum tube on the other side of the installation sleeve 11;

[0070] Step 5: After the formed end of the aluminum tube passes through the rotating plate 43 and the bending point of the aluminum tube is located at the position of the fixed column 42, the continuous extrusion of the aluminum tube is stopped, and the aluminum tube is firmly clamped by the multiple forming blocks 23 against the aluminum tube and the clamping rod 54 limiting the reverse return of the aluminum tube;

[0071] The controller inside the console 12 controls the piston rod of the electric push rod 47 to extend, and drives the fixed column 42 to move close to the formed aluminum tube through the push block 48 and the spring 412. Through a plurality of step-distributed bending stop grooves 411, the fixed column 42 is prompted to adapt to the bending side of the formed aluminum tubes of different sizes. When a certain bending stop groove 411 on the outer wall of the fixed column 42 contacts the aluminum tube, the fixed column 42 is restricted from moving continuously, and the push block 48 compresses the spring 412 to move continuously. In this process, with the help of the sliding of the guide pin 49 in the corresponding oblique guide groove 410, the fixed column 42 is forced to drive the bending rod 44 to rotate in combination with the rotating plate 43, so as to bend the formed aluminum tube.

[0072] Step 6: After the bending is completed, the electric push rod 47 drives the fixed column 42 to move toward the mounting platform 41. Under the torsional elastic force of the spring 412, the bending rod 44 is forced to separate from the aluminum tube, and then the movable plate 45 contacts the mounting platform 41 to ensure that the bending rod 44 is effectively reset and maintains the reset state.

[0073] Step 7: Continue to extrude the aluminum tube. At the same time, the controller in the control console 12 controls the servo motor 2 35 to drive the gear 36 to rotate. The engagement between the gear 36 and the outer gear ring 34 drives the rotating mounting ring 32 to rotate, adjust the angle of the mounting platform 41, and repeat the above bending steps to complete the bending processing of multiple and different bending angles of the aluminum tube.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
