Description

Technical Field

[0001] This invention relates to the field of cold bending forming equipment, and more specifically, to a cold bending forming machine for aluminum profiles. Background Technology

[0002] Aluminum profiles need to be extruded. First, a mold is designed and manufactured according to the cross-section of the profile product. The heated round cast rod is extruded from the mold using an extruder. The commonly used grade is 6063 alloy. During extrusion, an air-cooling quenching process and a subsequent artificial aging process are used to complete the heat treatment strengthening. Different grades of heat-treatable alloys have different heat treatment regimes. The aluminum profile cold bending forming machine uses multi-pass forming rollers arranged in sequence to continuously cold press the aluminum profile to form a profile with a specific cross-section.

[0003] When existing cold bending rollers are used to cold bend profiles, the friction between the rollers and the profiles is large, and a lot of heat is generated. Especially when the aluminum profiles are cold bent when they are still hot after being formed, the temperature of the aluminum profiles after cold bending is too high, the hardness is reduced, and it is not easy to set the shape. At the same time, the high temperature of the cold-bent profiles is also not conducive to the subsequent processing by the processing personnel.

[0004] Chinese patent (CN111672949B) discloses an aluminum profile cold bending forming machine. In operation, a main drive motor drives a main drive shaft to move individual cold bending rollers to cold bend the profile. The cold bending rollers sequentially bend the profile and also rotate sequentially over the top for cooling. After each cold bending roller is released from the profile pressure, it is rapidly cooled by a cooling fan. Airflow into the air-cooling tank also accelerates the cooling of the cold bending rollers. Individual cold bending rollers are spliced ​​together to sequentially bend the profile. This avoids the problem of excessive friction and heat generation between the entire cold bending roller and the profile during cold bending, which could affect the shaping of the aluminum profile.

[0005] However, in actual use, when processing aluminum profiles, one type of equipment can only process coils of one thickness, which limits the processing range of the equipment. Therefore, when processing aluminum profiles of different thicknesses, it is necessary to adjust the gap between the upper and lower rollers. However, there are many sets of rollers, and each adjustment of the rollers requires adjustment of one set at a time, which is done manually with a wrench. After adjustment, the equipment also needs to be debugged, which greatly wastes the equipment's usage time and increases the labor intensity of workers. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this invention is to provide an aluminum profile cold bending forming machine.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A cold bending forming machine for aluminum profiles includes a frame, with drive units provided on both sides of the outer surface of the frame, and multiple upper and lower pressure rollers arranged linearly inside the frame. Limiting grooves are provided on both sides of the outer surface of the frame, and a spacing adjustment mechanism is provided on both sides of the outer surface of the frame. The spacing adjustment mechanism includes a first limiting frame fixedly connected to both sides of the outer surface of the frame.

[0009] The first limiting frame is fixedly connected to the top of the first servo motor, and the output end of the first servo motor is fixedly connected to the first lead screw.

[0010] Furthermore, an inductive switch is provided at one end of the outer circular surface of the support rod, and a spacing measuring mechanism is provided on one side of the inner wall of the frame. The spacing measuring mechanism includes a second limiting frame fixedly connected to one side of the inner wall of the frame. A connecting block is fixedly connected to one side of the outer surface of the second limiting frame. The second limiting frame is fixedly connected to the inside of the frame through the connecting block. A second servo motor is fixedly connected to the top of the second limiting frame. A second lead screw is fixedly connected to the output end of the second servo motor. The second lead screw passes through the inside of the second limiting frame and is threadedly connected to a threaded sleeve.

[0011] Furthermore, an L-shaped connecting plate is fixedly connected to the other side of the outer circular surface of the threaded sleeve, and an infrared rangefinder is fixedly installed at one end of the L-shaped connecting plate, with the infrared rangefinder positioned directly above the placement plate.

[0012] Furthermore, a support platform is fixedly connected to one side of the outer surface of the frame, and two limiting rollers are provided inside the support platform. A placement plate is fixedly connected at the middle of the connection between the frame and the support platform, and a support plate is fixedly connected to the other side of the outer surface of the frame. The drive unit is used to drive the lower pressure roller inside the frame.

[0013] Furthermore, a roller groove is provided in the middle of the outer circular surface of the upper pressure roller, and a mold cleaning mechanism is provided on the top of the upper pressure roller. The mold cleaning mechanism includes a support frame fixedly connected to one end of the outer circular surface of the support rod, and a placement frame is fixedly connected to one end of the upper surface of the support frame. A first roller is provided inside the placement frame, and an adsorption belt is wound around the outer circular surface of the first roller.

[0014] Furthermore, both ends of the outer circular surface of the support rod are fixedly connected to L-shaped support rods. The support rod is fixedly connected to a first U-shaped frame through the two L-shaped support rods. A second roller is rotatably connected inside the first U-shaped frame. The second roller is rotatably connected to the first roller through an adsorption belt. The second roller is tangent to the roller groove of the upper pressure roller. The support frame is fixedly connected to a second U-shaped frame through two support plates. An electric roller is rotatably connected inside the second U-shaped frame.

[0015] Furthermore, a collection mechanism is provided on one side of the outer circular surface of the electric roller. The collection mechanism includes an L-shaped clamping plate fixedly connected to one side of the outer surface of the support plate. A collection box is provided on one side of the outer circular surface of the electric roller. Limiting plates are fixedly connected to both sides of the outer surface of the collection box. The limiting plates are fixedly connected to the L-shaped clamping plate through the limiting holes by threaded bolts. Multiple spring telescopic rods are fixedly connected inside the collection box. A scraper is fixedly connected to the top of the spring telescopic rods. The scraper is tangent to the outer circular surface of the electric roller.

[0016] Furthermore, limiting mechanisms are provided on both sides of the outer surface of the placement rack. The limiting mechanism includes limiting frames fixedly connected to both sides of the outer surface of the placement rack. Sliding grooves are provided on both sides of the top of the placement rack. A limiting rod is slidably connected inside the sliding groove. The limiting rod passes through the interior of the first roller and is slidably connected to the interior of the placement rack. Limiting rings are fixedly connected to both sides of the outer circular surface of the limiting rod. U-shaped rings are engaged at both ends of the outer circular surface of the limiting rod. The U-shaped rings pass through the interior of the limiting frames. A pull rod is fixedly connected to the top of each U-shaped ring.

[0017] Furthermore, the pull rod is T-shaped and is used for installing and removing the U-shaped ring.

[0018] Furthermore, the adsorption strip is made of a superconducting material and is used to adsorb aluminum shavings or other impurities generated during the manufacturing process of aluminum profiles.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) This solution is equipped with a spacing adjustment mechanism. Since it is time-consuming and labor-intensive to manually adjust the spacing between the upper and lower pressure rollers when processing aluminum profiles of different thicknesses, the first servo motor of the spacing adjustment mechanism can be started to make the first lead screw rotate, thereby causing the threaded support seat to drive the support rod to move upward, thus increasing the spacing between the upper and lower pressure rollers. Furthermore, multiple sets of gears are driven to rotate through the gear belt, so that the spacing of multiple sets of upper pressure rollers can be adjusted, which not only saves time and labor but also improves the overall work efficiency.

[0021] (2) By setting up an inductive switch and a spacing measuring mechanism, since the spacing between the upper and lower pressure rollers needs to be measured manually multiple times to ensure that the resulting spacing can be used to perform cold bending forming of aluminum profiles normally, this process is time-consuming and labor-intensive. Therefore, the second servo motor of the spacing measuring mechanism can be used to make the threaded sleeve drive the baffle to rise to a suitable distance. Thus, when the spacing adjustment mechanism is used, the inductive switch is blocked by the baffle and touched, thereby turning off the switch of the first servo motor of the spacing adjustment mechanism and automatically completing the upper and lower pressure roller spacing adjustment operation.

[0022] (3) By setting a spacing measuring mechanism, when processing aluminum profiles of different thicknesses, it is necessary to measure the thickness of the aluminum profile in order to obtain the required spacing and make adjustments. At this time, while the threaded sleeve rises, the L-shaped connecting plate can drive the infrared rangefinder to rise synchronously, thereby ensuring that the infrared rangefinder's measurement value returns to the initial setting value, so that the infrared rangefinder completes the measurement operation of the aluminum profile. Then, the second servo motor can automatically adjust the height of the baffle according to the measurement value to complete the upper and lower pressure roller spacing adjustment operation, further ensuring the accuracy of the spacing adjustment.

[0023] (4) By setting up a mold cleaning mechanism, aluminum chips will be generated in the mold during the processing of aluminum profiles, which will cause the surface of the aluminum profiles to be uneven when they are squeezed. Therefore, during the rolling of the upper pressure roller, the second roller rotates synchronously, which allows the adsorption belt to adsorb the aluminum chips in the roller groove. The adsorption belt is then wound up by an electric roller. This operation solves the problem of aluminum chips adsorbed in the mold, which affects the quality of the finished aluminum profile.

[0024] (5) By setting up a collection mechanism, when the adsorption belt with aluminum shavings is recycled, the aluminum shavings can be scraped off by a scraper, and the scraped aluminum shavings fall into the collection box and are recycled. At the same time, the spring telescopic rod can ensure that the scraper always scrapes off the aluminum shavings on the adsorption belt wound by the electric roller.

[0025] (6) By setting a limiting mechanism, when the adsorption belt on the first roller is used up, the U-shaped ring can be pulled out from the limiting frame, so that the limiting rod can be taken out from the slide groove of the placement frame, thus making it convenient for the staff to replace the new adsorption belt.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1 to 8 A cold bending forming machine for aluminum profiles includes a frame 1. Both sides of the outer surface of the frame 1 are provided with drive units 2. Multiple upper pressure rollers 4 and lower pressure rollers 3 are provided inside the frame 1. The upper pressure rollers 4 and lower pressure rollers 3 are arranged linearly inside the frame 1. Limiting grooves are opened on both sides of the outer surface of the frame 1. Spacing adjustment mechanisms 7 are provided on both sides of the outer surface of the frame 1. The spacing adjustment mechanism 7 includes a first limiting frame 71 fixedly connected to both sides of the outer surface of the frame 1.

[0043] The first servo motor 72 is fixedly connected to the top of the first limiting frame 71. The output end of the first servo motor 72 is fixedly connected to the first lead screw 73. The first lead screw 73 passes through the interior of the first limiting frame 71 and is rotatably connected to the threaded support seat 75. The threaded support seat 75 passes through the fixing groove of the first limiting frame 71 and the limiting groove of the frame 1 and is fixedly connected to the support rod 76. The outer circular surface of the support rod 76 is fitted with the upper pressure roller 4. One end of the outer circular surface of the first lead screw 73 is fixedly connected to the gear 74. The surface of the gear 74 is meshed with the gear belt 77.

[0044] Since manually adjusting the gap between the upper and lower pressure rollers is required when processing aluminum profiles of different thicknesses, which is time-consuming and labor-intensive, the first servo motor 72 can be started to rotate the first lead screw 73, thereby causing the threaded support seat 75 to move upward on the first lead screw 73, which in turn drives the support rod 76 to move upward synchronously. This process can increase the gap between the upper pressure roller 4 and the lower pressure roller 3, and drive multiple sets of gears 74 to rotate through the gear belt 77, so that the gap of multiple sets of upper pressure rollers 4 can be adjusted. This adjustment process does not require manual adjustment, which not only saves time and labor, but also improves the overall work efficiency.

[0045] like Figure 1 , Figure 2 , Figure 3As shown, an inductive switch 8 is provided at one end of the outer circular surface of the support rod 76, and a spacing measuring mechanism 9 is provided on one side of the inner wall of the frame 1. The spacing measuring mechanism 9 includes a second limiting frame 92 fixedly connected to one side of the inner wall of the frame 1. A connecting block 91 is fixedly connected to one side of the outer surface of the second limiting frame 92. The second limiting frame 92 is fixedly connected to the inside of the frame 1 through the connecting block 91. A second servo motor 93 is fixedly connected to the top of the second limiting frame 92. A second lead screw 94 is fixedly connected to the output end of the second servo motor 93. The second lead screw 94 passes through the inside of the second limiting frame 92 and is threadedly connected to a threaded sleeve 95. A baffle 97 is fixedly connected to one side of the outer circular surface of the threaded sleeve 95.

[0046] Because adjusting the distance between the upper and lower pressure rollers requires multiple manual measurements to ensure that the distance between the upper pressure roller 4 and the lower pressure roller 3 is sufficient for the cold bending of the aluminum profile, this process is time-consuming and labor-intensive. Therefore, after measuring the thickness of the aluminum profile to be processed, the second servo motor 93 can be started, causing the second lead screw 94 to drive the threaded sleeve 95 to rotate. This causes the threaded sleeve 95 to lift the baffle 97 to a suitable distance. When the appropriate height is adjusted, the position of the baffle 97 remains unchanged. As the support rod 76 lifts the upper pressure roller 4, the sensor switch 8 on its surface is blocked by the baffle 97 and touched, thus turning off the switch of the first servo motor 72 of the distance adjustment mechanism 7. This automatically completes the distance adjustment operation between the upper and lower pressure rollers, avoiding time differences during the distance adjustment process and preventing inaccurate distance adjustment.

[0047] like Figure 1 , Figure 3 As shown, an L-shaped connecting plate 96 is fixedly connected to the other side of the outer circular surface of the threaded sleeve 95. An infrared rangefinder 98 is fixedly installed at one end of the L-shaped connecting plate 96, and the infrared rangefinder 98 is positioned directly above the placement plate 6.

[0048] When processing aluminum profiles of different thicknesses, it is necessary to measure the thickness of the aluminum profiles to obtain the required spacing and make adjustments. At this time, while the threaded sleeve 95 rises, the L-shaped connecting plate 96 drives the infrared rangefinder 98 to rise synchronously, so that the infrared rangefinder 98 initially measures the distance between the placement plates 6 and records it. After the measurement is completed, the aluminum profile is placed on the placement plate 6. At this time, the infrared rangefinder 98 performs a new distance measurement operation (measuring the distance between the upper surfaces of the aluminum profiles). Through the two distance measurement operations, the intermediate difference is obtained, that is, the thickness data of the aluminum profile is obtained. At this time, the second servo motor 93 can be started, so that the second lead screw 94 drives the threaded sleeve 95 to rise, thereby causing the L-shaped connecting plate 96 to drive the infrared rangefinder 98 to rise again. The purpose of this operation is to make the measurement value of the infrared rangefinder 98 return to the initial setting value (the distance between the aluminum profiles before placement). Then, the second servo motor 93 can automatically adjust the height of the baffle 97 according to the measurement value to complete the upper and lower pressure roller spacing adjustment operation, further ensuring the accuracy of spacing adjustment.

[0049] like Figure 1 As shown, a support platform is fixedly connected to one side of the outer surface of the frame 1. Two limiting rollers 5 are provided inside the support platform. A placement plate 6 is fixedly connected at the middle of the connection between the frame 1 and the support platform. A tray is fixedly connected to the other side of the outer surface of the frame 1. The drive unit 2 is used to drive the lower pressure roller 3 inside the frame 1.

[0050] The drive unit 2 includes a drive gear, a drive motor, and a drive belt. In use, the drive motor of the drive unit 2 can be started, so that the drive belt meshes with the driven gears at both ends of the lower pressure roller 3 and rotates to complete the transmission operation of the entire device. This is existing technology and will not be described in detail here.

[0051] like Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a roller groove 41 is provided in the middle of the outer circular surface of the upper pressure roller 4, and a mold cleaning mechanism 10 is provided on the top of the upper pressure roller 4. The mold cleaning mechanism 10 includes a support frame 101 fixedly connected to one end of the outer circular surface of the support rod 76. A placement frame 102 is fixedly connected to one end of the upper surface of the support frame 101. A first roller 103 is provided inside the placement frame 102, and an adsorption belt 104 is wound around the outer circular surface of the first roller 103.

[0052] like Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, both ends of the outer circular surface of the support rod 76 are fixedly connected to L-shaped support rods 107. The support rod 76 is fixedly connected to a first U-shaped frame 106 through the two L-shaped support rods 107. A second roller 105 is rotatably connected inside the first U-shaped frame 106. The second roller 105 is rotatably connected to the first roller 103 through an adsorption belt 104. The second roller 105 is tangent to the roller groove 41 of the upper pressure roller 4. The support frame 101 is fixedly connected to a second U-shaped frame 109 through two support plates 1091. An electric roller 108 is rotatably connected inside the second U-shaped frame 109.

[0053] During the processing of aluminum profiles, aluminum shavings are generated in the mold. When the aluminum profile is squeezed, the aluminum shavings enter the aluminum profile, causing unevenness on its surface. Therefore, during the rolling of the upper pressure roller 4, the second roller 105 can rotate synchronously in the roller groove 41, thereby allowing the adsorption belt 104 to adsorb the aluminum shavings in the roller groove 41. At the same time, a new adsorption belt 104 is transferred from the first roller 103 to the second roller 105, automatically completing the replacement. The new adsorption belt 104 continues to perform the aluminum shavings adsorption operation. Meanwhile, the used adsorption belt 104 is wound up by the electric roller 108, reducing the cleaning burden on the workers. This operation also solves the problem of aluminum shavings adsorbed in the mold, affecting the quality of the finished aluminum profile.

[0054] like Figure 5 , Figure 6 , Figure 8 As shown, a collection mechanism 11 is provided on one side of the outer circular surface of the electric roller 108. The collection mechanism 11 includes an L-shaped clamping plate 111 fixedly connected to one side of the outer surface of the support plate 1091. A collection box 112 is provided on one side of the outer circular surface of the electric roller 108. Limiting plates 115 are fixedly connected to both sides of the outer surface of the collection box 112. The limiting plates 115 are fixedly connected to the L-shaped clamping plate 111 through the limiting hole 116 by threaded bolts. Multiple spring telescopic rods 113 are fixedly connected inside the collection box 112. A scraper 114 is fixedly connected to the top of the spring telescopic rods 113. The scraper 114 is tangent to the outer circular surface of the electric roller 108.

[0055] When the adsorption belt 104 with aluminum shavings is recycled, the aluminum shavings can be scraped off by the scraper 114, causing the scraped aluminum shavings to fall into the collection box 112 for recycling. At the same time, the spring telescopic rod 113 ensures that the scraper 114 always scrapes off the aluminum shavings on the adsorption belt 104 wound by the electric roller 108. While processing the aluminum shavings on the adsorption belt 104, the adsorption belt 104 will wrap around the electric roller 108 after use, making the outer diameter of the electric roller 108 larger. This allows the spring telescopic rod 113 to be compressed, ensuring that the scraper 114 is always attached to the electric roller 108 and can continuously clean up aluminum shavings.

[0056] like Figure 6 , Figure 7 As shown, limiting mechanisms 12 are provided on both sides of the outer surface of the placement rack 102. The limiting mechanism 12 includes a limiting frame 122 fixedly connected to both sides of the outer surface of the placement rack 102. Sliding grooves 121 are provided on both sides of the top of the placement rack 102. A limiting rod 123 is slidably connected inside the sliding groove 121. The limiting rod 123 passes through the interior of the first roller 103 and is slidably connected to the interior of the placement rack 102. Limiting rings 124 are fixedly connected to both sides of the outer circular surface of the limiting rod 123. U-shaped rings 125 are clamped at both ends of the outer circular surface of the limiting rod 123. The U-shaped rings 125 pass through the interior of the limiting frame 122. A pull rod 126 is fixedly connected to the top of the U-shaped rings 125.

[0057] like Figure 7 As shown, the pull rod 126 is T-shaped and is used to install and remove the U-ring 125.

[0058] When the adsorption belt 104 on the first roller 103 is used up, a new adsorption belt 104 needs to be replaced. At this time, the pull rod 126 can be held to pull the U-shaped ring 125 out of the limiting frame 122, and then the limiting rod 123 can be taken out of the slide groove 121 of the placement frame 102. Then, the new adsorption belt 104 can be wrapped around the first roller 103, so that the mold cleaning work can be carried out normally. This process not only makes it convenient to install the first roller 103, but also makes it convenient for the staff to replace the new adsorption belt 104, and improves the practicality of the whole device.

[0059] like Figure 7 As shown, the adsorption belt 104 is made of superconducting material and is used to adsorb aluminum shavings or other impurities generated during the manufacturing process of aluminum profiles.

[0060] Usage: First, based on the thickness of the aluminum profile, activate the spacing adjustment mechanism 7, causing the threaded support seat 75 to move the support rod 76 upwards, thereby adjusting the spacing between the upper pressure roller 4 and the lower pressure roller 3 to a suitable state. Simultaneously, during the spacing adjustment process, the spacing measuring mechanism 9 can cause the threaded sleeve 95 to raise the baffle 97 to a suitable distance. When the spacing adjustment mechanism 7 is used, the inductive switch 8 is blocked by the baffle 97 and touched, thus turning off the switch of the first servo motor 72 of the spacing adjustment mechanism 7, automatically completing the upper and lower pressure roller spacing adjustment operation. However, when processing aluminum profiles of different thicknesses, it is necessary to measure the thickness of the aluminum profile to obtain the required spacing and make adjustments, which is time-consuming and laborious. Therefore, while the threaded sleeve 95 rises, the L-shaped connecting plate 96 can simultaneously raise the infrared rangefinder 98, ensuring that the infrared rangefinder 98's measurement value returns to the initial setting value, allowing the infrared rangefinder 98 to complete the aluminum profile measurement operation. This allows the second servo motor 93 to automatically adjust the height of the baffle 97 based on the measurement value, thus completing the upper and lower pressure roller spacing adjustment. The adjustment operation further ensures the accuracy of the spacing adjustment. After the spacing adjustment is completed, the drive unit 2 can be activated, allowing the aluminum profile to pass through the limiting roller 5, and the placement plate 6 to support it. This allows the aluminum profile to be squeezed by the upper pressure roller 4 and the lower pressure roller 3 to obtain the required sheet material. However, during the processing, aluminum chips will be generated in the mold, causing the surface of the aluminum profile to be uneven when it is squeezed. Therefore, during the rolling of the upper pressure roller 4, the second roller 105 rotates synchronously, thereby causing the adsorption belt 104 to remove the aluminum chips in the roller groove 41. The adsorption process is carried out, and the used adsorption belt 104 is wound up by the electric roller 108. When the adsorption belt 104 with aluminum shavings is recycled, the aluminum shavings can be scraped off by the scraper 114 and fall into the collection box 112 for recycling. At the same time, when the adsorption belt 104 on the first roller 103 is used up, the U-shaped ring 125 can be pulled out from the limiting frame 122, so that the limiting rod 123 can be taken out from the slide groove 121 of the placement rack 102, thereby facilitating the staff to replace the new adsorption belt 104.
