Description

Technical Field

[0001] This invention relates to the field of aluminum alloy tube processing technology, and in particular to a method and equipment for producing aluminum alloy tubes for photosensitive drums. Background Technology

[0002] A pipe bevel is a slope formed at the joint when welding pipes together. The bevel allows the aluminum alloy tubes of the photosensitive drum to penetrate the weld during the butt joint, and the welding rod can directly reach the root of the weld, thus ensuring complete fusion of the weld and improving the stability of the photosensitive drum aluminum alloy tube welding. The bevel at the joint of the photosensitive drum aluminum alloy tubes is generally processed by a beveling machine.

[0003] Referring to Chinese Patent Publication No. CN 110328408 B, a pipe beveling machine is disclosed. In use, through the cooperation of structures such as snap-fit ​​components, the beveling cutter head is fixed to one side of the pipe, and the rotating device body can quickly complete the beveling work. Moreover, this process does not require the application of external force to the device, making the operation more labor-saving. At the same time, the effective radius of the snap-fit ​​components can be adjusted, so it is suitable for beveling pipes of different sizes, making it more practical. However, in use, it cannot expand the inside of the pipe from the inside, and when the pipe joint is beveling, the thickness of the pipe joint becomes smaller. When the beveling cutter head is beveling the pipe joint, it will apply a certain pressure to the pipe, making the pipe joint prone to deformation, thus affecting the quality of the beveling process.

[0004] Therefore, it is necessary to provide a production method and equipment for the aluminum alloy tube of the photosensitive drum to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with related technologies, the production equipment for photosensitive drum aluminum alloy tubes provided by this invention has the following beneficial effects:

[0017] 1. The present invention inflates the annular airbag by inflating the air intake component, thereby expanding the annular airbag from the inside to support the end of the aluminum alloy tube, reducing the probability of deformation of the end of the aluminum alloy tube due to pressure during beveling, and improving the quality of beveling of the aluminum alloy tube.

[0018] 2. The present invention allows the cooling water inside the protrusion to exchange heat with the end of the aluminum alloy tube, thereby effectively dissipating heat at the end of the aluminum alloy tube, reducing the probability of thermal deformation at the end of the aluminum alloy tube during beveling, and further improving the quality of beveling of the aluminum alloy tube.

[0019] 3. When using this invention, since the thickness of the aluminum alloy tube at the beveling point varies during the beveling process, the heat dissipation rate of the tube wall with different thicknesses at the beveling point tends to be uniform by effectively dissipating heat at the aluminum alloy tube end. This reduces the excessive internal stress at the end of the aluminum alloy tube caused by the different heat dissipation rates, further reduces the probability of deformation at the end of the aluminum alloy tube, and further improves the quality of the beveling process of the aluminum alloy tube.

[0020] 4. This invention allows for intermittent adjustment of the cooling water flow rate within the guide pipe via a speed regulating valve, thereby adjusting the water flow rate at the inlet outlet. Furthermore, since multiple protrusions correspond one-to-one with multiple outlets on the outer surface of the inlet pipe, adjusting the water flow rate at the outlets allows the water flow to impact the metal float, causing the float to impact the inner wall at the aluminum alloy pipe end, resulting in vibration at the aluminum alloy pipe end. This facilitates the removal of debris during beveling of the outer surface of the aluminum alloy pipe end, thus aiding in the beveling process at the aluminum alloy pipe end.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Please refer to the following: Figures 1 to 8 A production equipment for a photosensitive drum aluminum alloy tube includes: a base 4, wherein the base 4 is connected to an mounting ring 2 via a support mechanism 3; a cutting tool mechanism 1 with a rotating function, wherein the cutting tool mechanism 1 with a rotating function is connected to the mounting ring 2; and a heat dissipation expansion mechanism 5, wherein the heat dissipation expansion mechanism 5 is connected to the base 4.

[0032] It should be noted that: the aluminum alloy tubes that need to bevel are fixed and clamped by external clamps; and the cutting tool mechanism 1 with rotation function can bevel the ends of the aluminum alloy tubes; when beveling the ends of the aluminum alloy tubes, the expansion and support mechanism 5 with heat dissipation function can expand and support the ends of the aluminum alloy tubes from the inside, reducing the probability of deformation of the ends of the aluminum alloy tubes due to pressure during beveling, and improving the quality of beveling of the aluminum alloy tubes;

[0033] It should also be noted that the expansion support mechanism 5 with heat dissipation function can effectively dissipate heat from the ends of the aluminum alloy tube, reduce the probability of thermal deformation of the ends of the aluminum alloy tube during beveling, and further improve the quality of beveling of the aluminum alloy tube.

[0034] It should also be noted that: because the thickness of the bevel is different at the end of the aluminum alloy tube during the beveling process, by effectively dissipating heat at the end of the aluminum alloy tube, the heat dissipation rate of the tube wall with different thicknesses at the bevel tends to be uniform. This reduces the internal stress at the end of the aluminum alloy tube caused by the different heat dissipation rates, further reduces the probability of deformation at the end of the aluminum alloy tube, and further improves the quality of the beveling process of the aluminum alloy tube.

[0035] refer to Figure 1 and Figure 2 As shown, the cutting tool mechanism 1 with rotational function includes an external gear ring 13. The outer surface of the mounting ring 2 is rotatably connected to the concentrically arranged external gear ring 13 via a plane bearing. An electric motor 11 is mounted on the outer surface of the mounting ring 2. A gear 14 is fixedly connected to the output end of the electric motor 11, and the gear 14 meshes with the external gear ring 13. A mounting bracket is fixedly connected to the opposite side of the external gear ring 13 and the mounting ring 2. A first hydraulic cylinder 18 is mounted on the mounting bracket. A U-shaped tool holder 15 is fixedly connected to the output end of the first hydraulic cylinder 18. A cutting tool 16 for beveling the end face of the pipe is installed inside the U-shaped tool holder 15.

[0036] It should be noted that when the device is in use, the aluminum alloy tube that needs to be beveled is clamped and fixed by an external clamp; the motor 11 works, and the gear 14 drives the external gear ring 13 to rotate, thereby causing the cutting blade 16 to rotate. The first hydraulic cylinder 18 extends and retracts, so that the cutting blade 16 contacts the end of the aluminum alloy tube, and the cutting blade 16 can be bevel the end of the aluminum alloy tube.

[0037] refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the expansion mechanism 5 with heat dissipation function includes a baffle 54. A concentrically arranged water bladder 52 is connected to one side of the baffle 54. A concentrically arranged water inlet pipe 59 is fixedly connected inside the water bladder 52. Multiple water outlets are opened on the outer surface of the water inlet pipe 59, and one end of the water inlet pipe 59 passes through a through hole in the baffle 54 and connects to the water outlet of the water inlet assembly 55 mounted on the base 4. A drain pipe 58, communicating with the interior of the water bladder 52, is fixedly connected to the outer surface of the water bladder 52, and the drain pipe 58 passes through the through hole in the baffle 54. The outer surface of the water bladder 52... The surface of the water bladder 52 is integrally formed with multiple protrusions 57 that are interconnected and protrude outwards. The outer surface of the water bladder 52 is fixedly connected with a concentrically arranged annular air bladder 53. The annular air bladder 53 has a cavity inside for the protrusions 57 to be inserted into. The outer surface of the annular air bladder 53 is fixedly connected with an air inlet pipe that is interconnected with it. The air inlet pipe passes through a through hole in the baffle 54 and is connected to the air outlet of the air inlet assembly 56 installed on the base 4. The surface of the annular air bladder 53 opposite to the baffle 54 is fixedly connected with an exhaust pipe that is interconnected with it. An electromagnetic exhaust valve is installed on the exhaust pipe.

[0038] Note: The opening on one side of the aluminum alloy tube to be processed is blocked by the baffle 54; the outer diameter of the baffle 54 is slightly larger than the inner diameter of the aluminum alloy tube, and the edge of the baffle 54 is chamfered to avoid the baffle 54 interfering with the cutting tool 16.

[0039] It should also be noted that: both the water bladder 52 and the annular air bladder 53 enter the aluminum alloy tube and are close to the end of the aluminum alloy tube; pressing the baffle 54 inflates the annular air bladder 53 through the air intake component 56, thereby expanding the annular air bladder 53 from the inside, reducing the probability of deformation of the end of the aluminum alloy tube due to pressure during beveling, and improving the quality of beveling of the aluminum alloy tube. Since the annular air bladder 53 expands the end of the aluminum alloy tube from the inside, it can position the baffle 54, so that the baffle 54 is stably placed at the end of the aluminum alloy tube.

[0040] It should also be noted that cooling water can be injected into the water bladder 52 through the water inlet component 55. The cooling water can enter the protrusion 57, which is close to the end of the aluminum alloy tube. The cooling water in the protrusion 57 can exchange heat with the end of the aluminum alloy tube, thereby effectively dissipating heat at the end of the aluminum alloy tube. This reduces the probability of thermal deformation at the end of the aluminum alloy tube during beveling, further improving the quality of the beveling process. Since the thickness of the bevel at the end of the aluminum alloy tube varies during beveling, effective heat dissipation at the end of the aluminum alloy tube makes the heat dissipation rate of the tube wall with different thicknesses at the bevel tend to be uniform. This reduces the internal stress at the end of the aluminum alloy tube caused by different heat dissipation rates, further reducing the probability of deformation at the end of the aluminum alloy tube, and further improving the quality of the beveling process.

[0041] It should also be noted that cooling water can also cool the cutting tool 16, ensuring its strength, reducing the wear rate of the cutting tool 16, thereby increasing the service life of the cutting tool 16, and increasing the speed of beveling aluminum alloy tubes.

[0042] It should also be noted that the cooling water can be discharged through the drain pipe 58, thereby realizing the circulation of cooling water in the water bladder 52 and the protrusion 57, ensuring that the cooling water can always effectively dissipate heat at the port of the aluminum alloy tube.

[0043] refer to Figure 6 and Figure 7 As shown, the expansion mechanism 5 with heat dissipation function also includes a metal heat-conducting mesh 51 and heat-conducting columns 59b. The outer surface of the airbag 53 is fixedly connected to the metal heat-conducting mesh 51 for heat conduction. Multiple heat-conducting columns 59b are fixedly connected inside the protrusion 57, and the multiple protrusions 57 correspond one-to-one with the multiple water outlets opened on the outer surface of the water inlet pipe 59. One end of the heat-conducting column 59b passes through the airbag 53 and is connected to the metal heat-conducting mesh 51, and a metal float ball 59a that slides freely relative to it is strung on the heat-conducting column 59b.

[0044] It should be noted that the metal heat-conducting mesh 51 and the heat-conducting column 59b play a role in heat conduction, which facilitates the exchange of heat between the end of the aluminum alloy tube and the cooling water in the protrusion 37, thereby improving the heat dissipation effect at the end of the aluminum alloy tube.

[0045] It should also be noted that the metal float 59a can increase the contact area with the cooling water, which further facilitates heat dissipation at the port of the aluminum alloy tube.

[0046] refer to Figure 4 and Figure 8 As shown, the water inlet assembly 55 includes a water tank 555, the upper surface of the base 4 is fixedly connected to the water tank 555, and the outer surface of the water tank 555 is fixedly connected to a connecting pipe 554 communicating with it; the upper surface of the water tank 555 is fixedly connected to a water pump 553, the inlet of the water pump 553 is connected to one end of a suction pipe 556, and the other end of the suction pipe 556 passes through the water tank 555 and extends to the inner bottom of the water tank 555; the outlet of the water pump 553 is connected to one end of a guide pipe 551, and the other end of the guide pipe 551 is detachably connected to the water inlet pipe 59 while ensuring a seal, and a speed regulating valve 552 is installed on the guide pipe 551.

[0047] It should be noted that: external cooling water enters the water tank 555 through the connecting pipe 554, and the water pump 553 works to make the cooling water in the water tank 555 enter the water bladder 52 through the guide pipe 551, thereby realizing the filling of water bladder 52 and the inside of the protrusion 57 with water.

[0048] It should also be noted that the flow rate of cooling water in the guide pipe 551 can be adjusted intermittently by the speed regulating valve 552, and the speed of water flow at the outlet of the inlet pipe 59 can also be adjusted. Since the multiple protrusions 57 correspond one-to-one with the multiple outlets opened on the outer surface of the inlet pipe 59, by adjusting the speed of water flow at the outlet, the water flow can impact the metal float 59a, so that the metal float 59a can impact the inner wall at the end of the aluminum alloy pipe, causing the end of the aluminum alloy pipe to vibrate. This is beneficial for the falling off of debris when beveling the outer surface of the end of the aluminum alloy pipe, thus facilitating the beveling process at the end of the aluminum alloy pipe.

[0049] It should also be noted that the water flow can impact the metal float 59a, which facilitates the exchange of cooling water in the protrusion 57 with the cooling water in other parts of the water bladder 52, thereby ensuring that the cooling water in the protrusion 57 can be kept at a low temperature, which in turn helps to dissipate heat at the aluminum alloy tube port.

[0050] The other end of the guide pipe 551 is detachably connected to the inlet pipe 59 while ensuring a seal. That is, the guide pipe 551 is threadedly and sealed to the inlet pipe 59 through a water pipe threaded connector. The inlet pipe 59 and the guide pipe 551 can be installed and separated by rotating the water pipe threaded connector.

[0051] refer to Figure 4 and Figure 8 As shown, the air intake assembly 56 includes an air pump 563 and a bracket 564. The air pump 563 is fixedly connected to the upper surface of the base 4 via the bracket 564. The air outlet of the air pump 563 is connected to one end of the air guide pipe 561. The other end of the air guide pipe 561 is detachably connected to the air intake pipe while ensuring a seal. A one-way valve 562 is installed on the air guide pipe 561.

[0052] It should be noted that by operating the air pump 563, air can be injected into the annular airbag 53, causing the annular airbag 53 to expand and support the end of the aluminum alloy tube, reducing the probability of deformation of the end of the aluminum alloy tube due to pressure during beveling, and improving the quality of beveling of the aluminum alloy tube.

[0053] It should also be noted that when the annular airbag 53 needs to be removed, the air pump 563 stops working and the electromagnetic exhaust valve opens. The gas inside the annular airbag 53 is discharged through the electromagnetic exhaust valve, so that the annular airbag 53 no longer expands the aluminum alloy tube from the inside, allowing the annular airbag 53 to be removed from the aluminum alloy tube.

[0054] It should also be noted that the other end of the air guide tube 561 is detachably connected to the air intake tube while ensuring a seal. That is, the air guide tube 561 is connected to the air intake tube threadedly through the air tube threaded connector. The air guide tube 561 and the air intake tube can be installed and disassembled by rotating the air tube threaded connector.

[0055] In summary, the water inlet pipe 59 can be separated from the guide pipe 551, the air guide pipe 561 can be separated from the air inlet pipe, and the baffle 54 is detachably connected to the water bladder 52 via Velcro. When the Velcro is torn off, the baffle 54 can be separated from the water bladder 52, and the drain pipe 58, water inlet pipe 59, and air inlet pipe can all pass through the corresponding through holes of the baffle 54, so that the baffle 54 can be removed, which is convenient for replacing the baffle 54.

[0056] refer to Figure 3 As shown, the cutting tool mechanism 1 with rotation function also includes an angle adjustment component 17, and the U-shaped tool holder 15 is equipped with an angle adjustment component 17 for adjusting the operating angle of the cutting tool 16.

[0057] It should be noted that the angle of the cutting tool 16 can be adjusted by the angle adjustment component 17, thereby adjusting the angle of the aluminum alloy tube beveling process and improving the flexibility of the device. The adjustable angle of the aluminum alloy tube beveling process allows the device to meet different processing requirements and reduce the limitations of the device's use.

[0058] refer to Figure 3As shown, the angle adjustment assembly 17 includes a U-shaped fixed seat 171 and a rotating shaft 174. The U-shaped fixed seat 171 is fixedly connected inside the U-shaped tool holder 15. The cutting tool 16 is rotatably connected to the U-shaped fixed seat 171 through the rotating shaft 174. A second hydraulic cylinder 172 is fixedly connected to the U-shaped tool holder 15. A slider 175 is connected to the output end of the second hydraulic cylinder 172. The slider 175 is slidably connected to the slide rail 173, and the slide rail 173 is fixedly connected to the upper surface of the cutting tool 16.

[0059] It should be noted that the extension and retraction drive of the second hydraulic cylinder 173 can drive the slider 175 to move on the slide rail 173, thereby pushing the cutting tool 16 to rotate. This allows the operating angle of the cutting tool 16 to be adjusted within a certain range, thus adjusting the angle of the aluminum alloy tube beveling process within a certain range, improving the flexibility of the device. The angle of the aluminum alloy tube beveling process can be adjusted within a certain range, enabling the device to meet different processing needs and reducing the limitations of the device's use.

[0060] refer to Figure 1 and Figure 2 As shown, an annular protective cover 12 is fixedly connected to the outer surface of the mounting ring 2; the outer gear ring 13 is located inside the protective cover 12, and the protective cover 12 has an avoidance opening for avoiding the gear 14.

[0061] It should be noted that the protective cover 12 can protect the outer gear ring 13, reduce the probability of the outer gear ring 13 coming into contact with external objects when it rotates, thereby reducing the interference of external objects on the outer gear ring 13 and improving the reliability of the device.

[0062] It should also be noted that the protective cover 12 protects the outer gear ring 13, reducing the chance of operators accidentally coming into contact with the outer gear ring 13, thereby reducing the chance of operators being accidentally injured by the outer gear ring 13 and improving the safety of the device.

[0063] refer to Figure 1 As shown, the support mechanism 3 includes a third hydraulic cylinder 32, which is fixedly connected to the upper surface of the base 4. The output end of the third hydraulic cylinder 32 is fixedly connected to a support plate 31, and the support plate 31 is fixedly connected to the bottom outer surface of the mounting ring 2.

[0064] It should be noted that the extension and retraction drive of the third hydraulic cylinder 32 can drive the support plate 31 to move in the vertical direction, thereby adjusting the working height of the mounting plate 2. This allows it to be used with external clamps of different heights, improving the flexibility of the device and expanding its applicability.

[0065] The working principle of the production equipment for photosensitive drum aluminum alloy tubes provided by this invention is as follows:

[0066] In use, this invention uses an external clamp to hold and fix the aluminum alloy tube requiring beveling. The motor 11 drives the external gear ring 13 via the gear 14, causing the cutting tool 16 to rotate. The first hydraulic cylinder 18 extends and retracts, bringing the cutting tool 16 into contact with the end of the aluminum alloy tube, allowing for beveling. The invention also uses an air intake assembly 56 to inflate the annular airbag 53, expanding it and thus supporting the end of the aluminum alloy tube from the inside. This reduces the likelihood of deformation due to pressure during beveling, improving the quality of the beveling process. The expansion of the annular airbag 53 also helps to position the baffle 54, ensuring its stable placement at the end of the aluminum alloy tube. Finally, the water intake assembly 55 injects cooling water into the water bladder 52, which then enters the protruding portion. Within section 57, the cooling water within the protrusion 57 is close to the end of the aluminum alloy tube. This cooling water can exchange heat with the end of the aluminum alloy tube, effectively dissipating heat and reducing the likelihood of thermal deformation during beveling, thus improving the quality of the beveling process. Since the thickness of the bevel varies at the end of the aluminum alloy tube during beveling, effective heat dissipation at the end makes the heat dissipation rate of the tube wall at different thicknesses more uniform, reducing excessive internal stress at the end due to uneven heat dissipation rates, further reducing the likelihood of deformation and improving the quality of the beveling process. In use, the cooling water can also cool the cutting tool 16, ensuring its strength, reducing its wear rate, and thus increasing its service life, while simultaneously increasing the beveling speed of the aluminum alloy tube.

[0067] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
