Description

Technical Field

[0001] This invention relates to the field of aluminum product processing technology, and in particular to a positioning and stamping device for aluminum product processing. Background Technology

[0002] Piping is a common process in the manufacturing of aluminum tubes, and punching has gradually become the mainstream process due to its high efficiency and good cross-sectional quality. However, because aluminum has low hardness and good plasticity, thin-walled tubes are prone to wall denting or collapse under the impact force of the punch during punching, which seriously affects the accuracy of the hole shape and product quality.

[0003] In response to this, some improvements have been made in the existing technology, such as setting a fixed mandrel inside the tube to provide support. However, the position of the mandrel is fixed and it is difficult to adjust flexibly according to the changes in the hole position. When processing aluminum tubes with different diameters or hole position requirements, the position change of the internal support mechanism is very cumbersome and the equipment has poor versatility. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a positioning and stamping device for aluminum product processing. It solves the technical problem that the internal support mechanism in existing devices has a fixed support position and is difficult to adjust flexibly according to changes in hole position, resulting in poor equipment versatility. It has the advantages of adjustable support position and the ability to adapt to aluminum tube punching processing with different pipe diameters and hole position requirements.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a positioning and stamping device for aluminum product processing, comprising a processing table, wherein a loading station, an oil spraying station, a stamping station, and an unloading station are sequentially arranged on the periphery of the processing table along the process sequence; a circulating feeding mechanism is provided on the processing table, the circulating feeding mechanism comprising a rotating truncated cone rotatably mounted on the upper end of the processing table, and a plurality of limiting bases for placing aluminum tubes are provided on the rotating truncated cone; the circulating feeding mechanism is used to sequentially and cyclically convey the limiting bases to the loading station, the oil spraying station, the stamping station, and the unloading station. The stamping station is equipped with a stamping processing mechanism, which includes a stamping component for performing a punching action on the aluminum tube. The oil spraying station is equipped with a spraying component for spraying stamping oil onto the part of the aluminum tube to be punched. The limiting base is equipped with an anti-collapse inner support mechanism for internally supporting the tube wall of the aluminum tube. The anti-collapse inner support mechanism includes a telescopic round tube that can extend and retract axially and an elastic expansion sleeve disposed at the end of the telescopic round tube. The telescopic round tube is used to adjust the axial position of the elastic expansion sleeve, and the elastic expansion sleeve can expand radially to internally support the tube wall of the aluminum tube.

[0006] Preferably, the limiting base has a limiting circular groove, and a fixing cylinder is coaxially fixed at the center of the limiting circular groove. During stamping, the aluminum tube will be sleeved on the outside of the fixing cylinder and its end will be embedded in the limiting circular groove.

[0007] Preferably, the fixed cylinder has a circular air chamber inside, and a number of side wall grooves are equally spaced along the circumference on the inner wall of the circular air chamber. A sliding square column is slidably connected inside the side wall groove, and an arc-shaped limiting plate is fixedly connected to the end of the sliding square column. A gas supply component for inputting gas into the circular air chamber is fixedly installed in the middle of the rotating truncated cone. When the gas supply component inputs compressed gas into the circular air chamber through the pipeline, the sliding square column will slide outward under the action of air pressure, thereby causing the arc-shaped limiting plate to press against the inner wall of the aluminum tube and complete the end limiting.

[0008] Preferably, the spraying station is provided with an adjusting groove extending in the horizontal direction. A first mounting bracket is movably mounted on the adjusting groove, and the spraying component is fixedly mounted on the first mounting bracket. A drive screw that is threaded to the bottom of the first mounting bracket is movably mounted inside the adjusting groove. A drive knob that is fixedly connected to the drive screw is movably mounted on the outside of the processing table. When the drive knob is rotated, the drive screw will drive the first mounting bracket to slide horizontally along the adjusting groove to adjust the spraying position of the spraying component.

[0009] Preferably, a second mounting bracket is fixedly installed at the stamping station, and the stamping assembly is fixedly installed on the second mounting bracket. The stamping assembly includes a stamping drive and a punch disposed at the output end of the stamping drive. A fine-tuning mounting seat is provided between the punch and the output end of the stamping drive. The fine-tuning mounting seat is used to adjust the position of the punch relative to the second mounting bracket in the horizontal direction.

[0010] Preferably, a fixed cylindrical tube is coaxially fixedly installed on the fixed cylindrical tube, and a telescopic cylindrical tube is threaded to the outside of the fixed cylindrical tube. When the telescopic cylindrical tube is rotated, the telescopic cylindrical tube will move along the axial direction of the fixed cylindrical tube.

[0011] Preferably, the elastic expansion sleeve has a cylindrical structure, and the cylindrical wall of the elastic expansion sleeve has multiple axially extending expansion openings evenly opened along the circumference. The inner hole of the elastic expansion sleeve is a conical hole, and an electric telescopic rod is installed inside the telescopic tube. One end of the electric telescopic rod is fixedly connected to a fixed cylinder, and the extended end of the electric telescopic rod is fixedly connected to a conical expansion core that matches the conical hole. When the electric telescopic rod extends, it drives the conical expansion core to squeeze into the conical hole of the elastic expansion sleeve axially, thereby forcing the elastic expansion sleeve to expand radially.

[0012] Preferably, the rotating platform is provided with an adaptive lifting mechanism for supporting the aluminum tube from below. The adaptive lifting mechanism includes a mounting steel frame fixedly installed on the rotating platform, and an arc-shaped support plate is movably installed on the mounting steel frame. The arc-shaped support plate is located below the telescopic tube. After the aluminum tube is inserted laterally into the limiting groove, the arc-shaped support plate will contact the outer wall of the aluminum tube, thereby supporting and lifting it.

[0013] Preferably, a hydraulic telescopic rod for adjusting the lifting height is provided between the mounting steel frame and the arc-shaped support plate. The arc-shaped support plate is driven to rise and fall by the extension and retraction of the hydraulic telescopic rod, which can adapt to aluminum pipes of different diameters.

[0014] Preferably, a buffer pad is detachably installed on the side of the arc-shaped support plate that contacts the aluminum pipe. The upper surface of the buffer pad is an arc-shaped surface that matches the outer wall of the aluminum pipe, and the material hardness of the buffer pad is lower than that of the aluminum pipe, so as to avoid scratching the outer wall of the aluminum pipe when lifting it.

[0015] By means of the above technical solution, the present invention provides a positioning and stamping device for aluminum product processing, which has at least the following beneficial effects: 1. This invention achieves rapid centering and clamping of aluminum tubes on the limiting base by setting a circular air chamber and a sliding square column inside a fixed cylinder, and using air pressure to drive an arc-shaped limiting plate to simultaneously press against the tube wall. This can be coordinated with the axial position adjustment of the telescopic circular tube in subsequent work stations, ensuring the positional accuracy and stability of the aluminum tubes during rotary conveying and stamping processes.

[0016] 2. This invention achieves automatic cyclic conveying of aluminum tubes between various workstations through the cooperation of a rotating frustum and multiple limiting bases. Each workstation can work independently at the same time, which can significantly improve processing efficiency and avoid the time waste caused by frequent loading and unloading of traditional single-workstation equipment.

[0017] 3. By setting a horizontally sliding first mounting bracket and a drive screw at the oil spraying station, the present invention realizes the rapid adjustment of the spraying position of the spraying component. It can flexibly adjust the spraying position according to different pipe diameters and different hole positions, ensuring that the stamping oil can accurately cover the area to be processed, which can effectively improve the quality of the punching cross section and extend the mold life.

[0018] 4. This invention allows for fine-tuning of the horizontal position of the punch by setting a fine-tuning mounting base, which can be coordinated with the axial adjustment of the telescopic tube. This enables independent adjustment of the punch in the horizontal direction and the inner support in the axial direction, and can flexibly adapt to punching processes of different specifications of aluminum tubes and different hole position requirements, significantly improving the versatility of the device.

[0019] 5. This invention, by coaxially setting a fixed cylindrical tube and a threaded telescopic cylindrical tube on a fixed cylinder, allows for stepless axial adjustment of the elastic expansion sleeve support position by rotating the telescopic cylindrical tube. It can flexibly adjust the inner support position according to different hole positions on the aluminum tube, avoiding the tedious operation of replacing the inner support components one by one for aluminum tubes of different specifications.

[0020] 6. This invention utilizes an electric telescopic rod to drive a conical expansion core into a conical hole, thereby forcing the elastic expansion sleeve to expand radially. This can form a uniform annular surface support inside the pipe wall during punching. Compared with the point support or line contact of a fixed mandrel, this can effectively disperse punching stress and prevent the pipe wall from undergoing local depression or collapse deformation under the impact force of the punch.

[0021] 7. This invention achieves automatic adaptation of the lifting height to changes in pipe diameter by setting up a steel frame and hydraulic telescopic rod on a rotating platform to drive the arc-shaped support plate to rise and fall. In conjunction with the radial expansion support of the elastic expansion sleeve in Embodiment 3, it can simultaneously constrain the pipe wall from both the inner and outer sides, effectively disperse the punching force, and further suppress the collapse and deformation of the pipe wall during the punching process.

[0022] 8. By setting a buffer pad on the arc-shaped support plate, the present invention can ensure stable lifting while avoiding scratching the pipe wall. This is especially beneficial for the processing of aluminum products with high surface quality requirements. Moreover, the pad can be replaced separately after it wears out, reducing maintenance costs. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1 Aluminum has low hardness and good plasticity. During punching, thin-walled tubes are prone to wall denting or collapse under the impact force of the punch. In existing devices, the internal support mechanism has a fixed support position, making it difficult to flexibly adjust according to changes in the hole position, resulting in poor equipment versatility. To address this technical deficiency in the existing technology, such as... Figures 1-6 As shown, this embodiment proposes a positioning and stamping device for aluminum product processing. The support position is adjustable and can be adapted to the punching processing of aluminum tubes with different diameters and hole positions. The device includes a processing table 1. The processing table 1 is provided with a feeding station 101, an oil spraying station 102, a stamping station 103 and an unloading station 104 in sequence along the process order. A circulating feeding mechanism 2 is provided on the processing table 1.

[0027] Specifically, the circulating feeding mechanism 2 includes a rotating frustum 201 rotatably mounted on the upper end of the processing table 1. The rotating frustum 201 is equipped with multiple limiting bases 202 for placing aluminum tubes 6. The circulating feeding mechanism 2 is used to sequentially and cyclically transport each limiting base 202 to the loading station 101, the spraying station 102, the stamping station 103, and the unloading station 104. Limiting bases 202 have limiting grooves 203. A fixing cylinder 204 is coaxially fixed at the center of the limiting groove 203. During stamping, the aluminum tube 6 is sleeved on the outside of the fixing cylinder 204, with its end embedded in the limiting groove 203. The interior of the 4 has a circular air chamber 205. The inner wall of the circular air chamber 205 has several side wall grooves 206 evenly spaced along the circumference. The inside of the side wall grooves 206 is slidably connected to a sliding square column 208. The end of the sliding square column 208 is fixedly connected to an arc-shaped limiting plate 207. The middle of the rotating frustum 201 is fixedly installed with a gas supply component 209 for inputting gas into the circular air chamber 205. When the gas supply component 209 inputs compressed gas into the circular air chamber 205 through the pipeline, the sliding square column 208 will slide outward under the action of air pressure, so that the arc-shaped limiting plate 207 presses against the inner wall of the aluminum tube 6 to complete the end limiting.

[0028] As can be seen from the above, during processing, the rotating frustum 201 will drive each limiting base 202 to rotate intermittently between the four workstations. When the limiting base 202 rotates to the loading workstation 101, the operator will put the aluminum tube 6 on the outside of the fixed cylinder 204 and embed the tube end into the limiting circular groove 203. At the same time, the air supply component 209 will input compressed gas into the circular air chamber 205. Subsequently, the air pressure will push each sliding square column 208 to slide outward along the side wall sliding groove 206, so that the arc-shaped limiting plate 207 is pressed against the inner wall of the aluminum tube 6, realizing the radial positioning and clamping of the aluminum tube 6 on the limiting base 202.

[0029] Subsequently, the rotating platform 201 continues to rotate, sequentially sending the limiting base 202 holding the aluminum tube 6 to the spraying station 102, the stamping station 103 and the unloading station 104, where spraying, punching and unloading operations are completed respectively, thereby realizing the continuous cyclic processing of the aluminum tube 6.

[0030] This embodiment achieves rapid centering and clamping of the aluminum tube 6 on the limiting base 202 by setting a circular air chamber 205 and a sliding square column 208 inside the fixed cylinder 204, and using air pressure to drive the arc-shaped limiting plate 207 to simultaneously press against the tube wall. This can be coordinated with the axial position adjustment of the telescopic circular tube 402 in subsequent workstations, ensuring the positional accuracy and stability of the aluminum tube 6 during rotary conveying and stamping processes. Moreover, this embodiment achieves automatic cyclic conveying of the aluminum tube 6 between workstations by cooperating with the rotating frustum 201 and multiple limiting bases 202. Each workstation can work independently at the same time, which can significantly improve processing efficiency and avoid the time waste caused by frequent loading and unloading of traditional single-station equipment.

[0031] Example 2 To achieve automatic spraying of stamping oil and position adjustment of the stamping assembly 307, based on Example 1, such as... Figure 1 , Figure 2 as well as Figure 7 As shown, in this embodiment, a stamping processing mechanism 3 is provided at the stamping station 103. Specifically, the stamping processing mechanism 3 includes a stamping component 307 for performing a punching action on the aluminum tube 6, and a spraying component 305 for spraying stamping oil onto the part of the aluminum tube 6 to be punched at the oil spraying station 102. An adjusting slide 302 extending horizontally is provided at the oil spraying station 102. A first mounting bracket 301 is movably mounted on the adjusting slide 302, and the spraying component 305 is fixedly mounted on the first mounting bracket 301. A drive screw 303 that is threadedly engaged with the bottom of the first mounting bracket 301 is movably mounted inside the adjusting slide 302. The processing table 1 A drive knob 304 is movably mounted on the outside and fixedly connected to the drive screw 303. When the drive knob 304 is rotated, the drive screw 303 will drive the first mounting bracket 301 to slide horizontally along the adjustment slide 302 to adjust the spraying position of the spraying component 305. A second mounting bracket 306 is fixedly mounted at the stamping station 103. The stamping component 307 is fixedly mounted on the second mounting bracket 306. The stamping component 307 includes a stamping drive and a punch set at the output end of the stamping drive. A fine-tuning mounting seat is provided between the punch and the output end of the stamping drive. The fine-tuning mounting seat is used to adjust the position of the punch relative to the second mounting bracket 306 in the horizontal direction.

[0032] As can be seen from the above, before the processing begins, the operator will rotate the drive knob 304 to drive the drive screw 303 to rotate according to the processing needs. When the drive screw 303 rotates, the first mounting bracket 301 will slide horizontally along the adjustment slide 302, thereby adjusting the spraying assembly 305 to the optimal spraying position.

[0033] Subsequently, when the circulating feeding mechanism 2 transports the limiting base 202 carrying the aluminum tube 6 to the oil spraying station 102, the spraying component 305 will automatically spray stamping oil onto the part of the aluminum tube 6 to be punched.

[0034] Next, the limiting base 202 will be conveyed to the stamping station 103, at which time the stamping drive component of the stamping assembly 307 will drive the punch to move downward, thereby performing a punching action on the aluminum tube 6.

[0035] This embodiment achieves rapid adjustment of the spraying position of the spraying component 305 by setting a horizontally sliding first mounting bracket 301 and a drive screw 303 at the oil spraying station 102. It can flexibly adjust the spraying position according to different pipe diameters and hole positions, ensuring that the stamping oil can accurately cover the area to be processed, which can effectively improve the quality of the punching cross-section and extend the mold life. Moreover, this embodiment sets a fine-tuning mounting seat to fine-tune the horizontal position of the punch, which can cooperate with the axial adjustment of the telescopic round tube 402 to achieve independent adjustment of the punch in the horizontal direction and the inner support in the axial direction. It can flexibly adapt to the punching processing of different specifications of aluminum tubes and different hole position requirements, significantly improving the versatility of the device.

[0036] Example 3 To achieve internal support for the aluminum tube wall during punching to prevent collapse and deformation, based on the above embodiments, such as... Figure 1 , Figure 8 as well as Figure 9 As shown, in this embodiment, an anti-collapse inner support mechanism 4 is provided on the limiting base 202 to internally support the wall of the aluminum tube 6. Specifically, the anti-collapse inner support mechanism 4 includes a telescopic circular tube 402 that can extend and retract axially and an elastic expansion sleeve 403 disposed at the end of the telescopic circular tube 402. The telescopic circular tube 402 is used to adjust the axial position of the elastic expansion sleeve 403. The elastic expansion sleeve 403 can expand radially to internally support the wall of the aluminum tube 6. The elastic expansion sleeve 403 has a cylindrical structure. The wall has multiple axially extending expansion openings evenly distributed along its circumference. The inner hole of the elastic expansion sleeve 403 is a tapered hole. An electric telescopic rod 404 is installed inside the telescopic tube 402. One end of the electric telescopic rod 404 is fixedly connected to the fixed cylinder 204. The extended end of the electric telescopic rod 404 is fixedly connected to a conical expansion core 405 that matches the tapered hole. When the electric telescopic rod 404 extends, it drives the conical expansion core 405 to be squeezed into the tapered hole of the elastic expansion sleeve 403 along the axial direction, thereby forcing the elastic expansion sleeve 403 to expand radially.

[0037] As can be seen from the above, before processing, the operator will rotate the telescopic tube 402 to move it along the axial direction of the fixed tube 401 according to the position of the hole to be punched on the aluminum tube 6, thereby adjusting the elastic expansion sleeve 403 to the support point corresponding to the position of the hole to be punched, so as to realize the flexible pre-adjustment of the support position.

[0038] When the aluminum tube 6 is fitted outside the fixed cylinder 204 and transported to the stamping station 103 along with the limiting base 202, the electric telescopic rod 404 will be activated and extended, driving the conical expansion core 405 to be axially squeezed into the conical hole of the elastic expansion sleeve 403. Since the elastic expansion sleeve 403 has multiple expansion openings on its cylindrical wall and its inner hole is conical, the squeezing of the conical expansion core 405 will generate a radial component force, which will evenly expand each expansion block of the elastic expansion sleeve 403 outward, so that the outer wall of the elastic expansion sleeve 403 is tightly attached to the inner wall of the aluminum tube 6, thereby forming a comprehensive annular support at the punching position.

[0039] After punching is completed, the electric telescopic rod 404 retracts, the conical expansion core 405 exits the elastic expansion sleeve 403, and the expansion sleeve recovers to its initial diameter by its own elasticity, releasing the support to the pipe wall.

[0040] In this embodiment, a fixed cylindrical tube 401 and a threaded telescopic cylindrical tube 402 are coaxially arranged on a fixed cylindrical tube 204. By rotating the telescopic cylindrical tube 402, the axial stepless adjustment of the support position of the elastic expansion sleeve 403 can be achieved. The position of the inner support can be flexibly adjusted according to different holes on the aluminum tube 6, avoiding the tedious operation of replacing the inner support components one by one for aluminum tubes 6 of different specifications. Moreover, in this embodiment, the electric telescopic rod 404 drives the conical expansion core 405 to be squeezed into the conical hole to force the elastic expansion sleeve 403 to expand radially. This can form a uniform annular surface support inside the tube wall during punching. Compared with the point support or line contact of the fixed core rod, it can effectively disperse the punching stress and avoid the tube wall from local denting or collapse deformation under the impact force of the punch.

[0041] Example 4 To provide auxiliary support for the aluminum tube 6 from below during punching to further improve the anti-collapse effect, based on the above embodiments, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 10As shown, this embodiment has an adaptive lifting mechanism 5 on the rotating frustum 201 for supporting the aluminum tube 6 from below. Specifically, the adaptive lifting mechanism 5 includes a mounting steel frame 501 fixedly installed on the rotating frustum 201. An arc-shaped support plate 502 is movably installed on the mounting steel frame 501. The arc-shaped support plate 502 is located below the telescopic tube 402. After the aluminum tube 6 is inserted laterally into the limiting groove 203, the arc-shaped support plate 502 will contact the outer wall of the aluminum tube 6, thereby supporting and lifting it. A hydraulic telescopic rod 503 for adjusting the lifting height is provided between the frame 501 and the arc-shaped support plate 502. The arc-shaped support plate 502 is driven to rise and fall by the extension and retraction of the hydraulic telescopic rod 503, which can adapt to aluminum pipes 6 of different diameters. A buffer pad can be detachably installed on the side of the arc-shaped support plate 502 that contacts the aluminum pipe 6. The upper surface of the buffer pad is an arc-shaped surface that matches the outer wall of the aluminum pipe 6, and the hardness of the buffer pad material is lower than that of the aluminum pipe 6 material, so as to avoid scratching the outer wall of the aluminum pipe 6 when lifting.

[0042] As can be seen from the above, when the aluminum tube 6 is inserted laterally into the limiting groove 203, the hydraulic telescopic rod 503 will automatically extend the corresponding stroke according to the current diameter of the aluminum tube 6, driving the arc-shaped support plate 502 to rise, so that the arc-shaped surface of the upper surface of the arc-shaped support plate 502 fits against the bottom outer wall of the aluminum tube 6, and together with the limiting groove 203 on the limiting base 202, forms a stable support for the tube.

[0043] At the stamping station 103, the arc-shaped support plate 502 will always support the aluminum tube 6 from below, which, together with the anti-collapse inner support mechanism 4 radially tightening from the inside and the end limit of the arc-shaped limiting plate 207, forms a multi-point constraint on the aluminum tube 6.

[0044] This embodiment achieves automatic adaptation of the lifting height to changes in pipe diameter by installing a steel frame 501 and a hydraulic telescopic rod 503 on the rotating frustum 201 to drive the arc-shaped support plate 502 to rise and fall. In conjunction with the radial expansion support of the elastic expansion sleeve 403 in embodiment three, it can simultaneously constrain the pipe wall from both the inner and outer sides, effectively dispersing the punching force and further suppressing the collapse and deformation of the pipe wall during the stamping process. Moreover, by setting a buffer pad on the arc-shaped support plate 502, this embodiment can avoid scratching the pipe wall while ensuring stable lifting, which is particularly advantageous for processing aluminum products with high surface quality requirements. Furthermore, the pad can be replaced individually after wear, reducing maintenance costs.

[0045] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
