Description

Technical Field

[0001] This application relates to the technical field of aluminum alloy processing, and in particular to a device for feeding and expanding holes in aluminum alloy forgings. Background Technology

[0002] Aluminum alloy forgings are widely used in aerospace, automotive manufacturing, and rail transportation due to their advantages such as light weight, high strength, and good corrosion resistance. In the production of aluminum alloy ring forgings, hole expansion is one of the key forming processes—by expanding the hole in the ring blank after upsetting and punching, its inner and outer diameters are increased to the target dimensions.

[0003] Currently, the reaming process commonly employs a frame reaming technique, which uses a frame and mandrel to radially expand and shape annular blanks. However, current loading operations still rely on manual labor: before reaming, the cut aluminum tube needs to be transported to the reaming equipment's working position, and then manually positioned on the reaming machine. The reaming machine then extrudes the aluminum tube, rolling it through intermediate bearings of varying diameters to achieve the required length and diameter. However, manual handling is not only labor-intensive and inefficient, but the positioning and fixing of the blank on the reaming equipment still requires manual assistance, further hindering the improvement of automation in the reaming process of aluminum alloy forgings. Summary of the Invention

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The aluminum alloy forging hole expansion and feeding device of this application embodiment is described below with reference to the accompanying drawings.

[0022] like Figures 1-7 As shown, the aluminum alloy forging hole-expanding and feeding device of this application embodiment may include a hole-expanding mechanism 1, a feeding mechanism 2, and a shrinkage component 3.

[0023] The feeding mechanism 2 and the shrinking component 3 are both installed on the expanding mechanism 1, and the feeding mechanism 2 and the shrinking component 3 are arranged opposite to each other. The shrinking component 3 is used to adjust the position of the support in the expanding mechanism 1 so as to unload the aluminum alloy forging after the hole is expanded.

[0024] It should be noted that the shrinkage component 3 described in the above embodiment is an electric telescopic rod, which completes the shrinkage and repositioning of the support on the hole-expanding mechanism 1, and then completes the unloading of the aluminum tube after hole expansion.

[0025] The feeding mechanism 2 may include a fixed frame 21, a feeding component 22, a storage component 23, and a feeding component 24.

[0026] It should be noted that the material storage component 23 described in the above embodiment can be connected to the unloading end of the aluminum tube cutting machine (not shown in the figure), so that the aluminum tube falls directly into the material storage component 23 after being cut, which facilitates the subsequent feeding operation of the aluminum tube by the feeding component 24.

[0027] The fixed frame 21 is mounted on the hole-expanding mechanism 1. The feeding component 22 and the storage component 23 are respectively mounted on the fixed frame 21. The feeding component 24 is mounted on the storage component 23. The feeding component 24 is used to transport the aluminum alloy forging to be expanded in the storage component 23 to the hole-expanding mechanism 1.

[0028] Understandably, the installation of the feeding component 22 is completed under the action of the fixing frame 21, and the automatic feeding process of the aluminum tube before hole enlargement is completed under the action of the feeding component 22. Then, during the feeding process of the feeding component 22, the driving of the feeding component 24 is completed, and the feeding process of the aluminum tube stored in the storage component 23 is completed under the action of the feeding component 24, and the replenishment of aluminum tubes is completed during the feeding process of the feeding component 22.

[0029] Specifically, such as Figure 6 As shown, the feeding assembly 22 may include a mounting frame 221, a transmission component 222, and a material storage component 223.

[0030] It should be noted that one end of the transmission component 222 described in the above embodiment is rotatably mounted on the hole-expanding mechanism 1, thereby supporting one end of the transmission component 222.

[0031] The mounting bracket 221 is mounted on the fixed bracket 21, the transmission component 222 is mounted on the mounting bracket 221, and the material storage component 223 is connected to the transmission component 222.

[0032] Understandably, the installation of the transmission component 222 is completed under the action of the mounting bracket 221. Subsequently, the material storage component 223 swings under the drive of the transmission component 222, thereby realizing the receiving of material from the feeding component 24 and the transfer to the hole-expanding mechanism 1 for hole-expanding operation.

[0033] To further clarify the above embodiment, in one embodiment of this application, the transmission component 222 may include a reciprocating motor 2221, a power rod 2222, a swing seat 2223, an electric push rod 2224, and a top plate 2225.

[0034] It should be noted that one end of the swing seat 2223 described in the above embodiment is rotatably connected to the hole expansion mechanism 1, thereby achieving stable support for one end of the swing seat 2223.

[0035] Among them, the reciprocating motor 2221 is mounted on the mounting frame 221, the swing seat 2223 is connected to the output end of the reciprocating motor 2221 through the power rod 2222, the electric push rod 2224 is mounted on the mounting frame 221, the top plate 2225 is mounted on the extended end of the electric push rod 2224, and the top plate 2225 is set towards the material storage component 223.

[0036] Understandably, driven by the reciprocating motor 2221, the power rod 2222 drives the swing seat 2223 to swing back and forth, thereby driving the storage component 223 to complete the receiving and sealing of the aluminum tube, preventing the continuous feeding of subsequent aluminum tubes, and under the push of the electric push rod 2224, the top plate 2225 pushes the aluminum tube into the enlarged hole position, ensuring the accuracy and stability of the feeding position.

[0037] Furthermore, such as Figure 6 As shown, the material storage component 223 includes an abutment frame 2231 and a material storage rack 2232.

[0038] It should be noted that the storage rack 2232 described in the above embodiment is bolted to the swing seat 2223, and the storage rack 2232 is provided with a placement slot for placing aluminum tubes. Thus, when facing aluminum tubes of different diameters, the abutment frame 2231 and the storage rack 2232 can be replaced to accommodate aluminum tubes of different diameters.

[0039] The abutment frame 2231 is installed on the storage rack 2232, the storage rack 2232 is installed on the swing seat 2223, and the abutment frame 2231 is in contact with the feeding component 24.

[0040] It is understood that the abutment frame 2231 described in the above embodiments is arc-shaped and always fits against the feeding end of the feeding component 24 during the swinging process.

[0041] Specifically, when the storage rack 2232 swings with the swing seat 2223, the abutment frame 2231 swings together with the storage rack 2232. When the placement groove on the storage rack 2232 comes into contact with the aluminum tube in the feeding assembly 24, the aluminum tube falls into the placement groove. During the process of the swing seat 2223 driving the storage rack 2232 to reset, the abutment frame 2231 always contacts the unloading end of the feeding assembly 24, thereby preventing the aluminum tube from continuously slipping out of the feeding assembly 24, ensuring that the quantity of material fed at one time is controllable, and avoiding the accumulation of aluminum tubes that may cause jamming and falling during feeding.

[0042] Specifically, such as Figure 6 As shown, the material storage assembly 23 includes a material storage box 231 and a discharge plate 232.

[0043] As a possible scenario, the storage bin 231 can be directly connected to the unloading end of the aluminum tube cutting machine (not shown in the figure), so that the cut aluminum tubes fall directly into it and enter the feeding assembly 24 in an orderly manner under the guidance of the unloading plate 232 to wait for feeding, thereby improving the continuity and automation of the overall production line.

[0044] The storage bin 231 is mounted on the fixed frame 21, the unloading plate 232 is mounted on the storage bin 231, and the unloading plate 232 is inclined downwards and faces the feeding assembly 24. The storage bin 231 is located at one end of the storage rack 2232.

[0045] Understandably, the storage bin 231 stores the aluminum tubes, and the unloading plate 232 facilitates the entry of the aluminum tubes into the feeding assembly 24, thereby achieving continuous feeding.

[0046] Specifically, such as Figure 6 As shown, the feeding assembly 24 may include multiple sets of stepped plates 241, linkage plates 242, multiple sets of movable plates 243, and a feeding frame 244.

[0047] It should be noted that the length of the movable plate 243 described in the above embodiment is longer than that of the step plate 241, so that when the movable plate 243 descends, it can ensure that the aluminum tube on the unloading plate 232 rolls onto the movable plate 243, and when it rises, the aluminum tube on the movable plate 243 can roll onto the step plate 241 from the inclined surface at the top.

[0048] It should be noted that the top surfaces of the multiple sets of stepped plates 241 and multiple sets of movable plates 243 described in the above embodiments are all inclined, and the inclined downward end is set towards the unloading frame 244, so that the aluminum tube can continuously fall from the movable plate 243 onto the stepped plate 241 during the feeding process, which facilitates the continuous feeding of aluminum tubes.

[0049] Among them, multiple sets of stepped plates 241 are installed on the storage box 231, multiple sets of movable plates 243 are slidably arranged between adjacent stepped plates 241, the linkage plate 242 is connected to the movable plate 243, the feeding frame 244 is installed on the storage box 231, and the feeding end face of the feeding frame 244 abuts against the abutting frame 2231.

[0050] It should be noted that one end of the linkage plate 242 described in the above embodiment is in contact with the abutment frame 2231, and a baffle is installed on the end of the linkage plate 242 away from the abutment frame 2231 to prevent the abutment frame 2231 from falling off the linkage plate 242.

[0051] It should be noted that the unloading end face of the unloading end 244 described in the above embodiment always remains in contact with the abutment frame 2231 during the swinging process of the abutment frame 2231, to prevent the aluminum tube from accidentally slipping out.

[0052] It should be noted that the movable plate 243 described in the above embodiment is elastically mounted on the storage box 231 by an elastic element (e.g., a spring), so that it can automatically reset under the action of elastic force when the abutment frame 2231 is disengaged from the linkage plate 242, and push the aluminum tube towards the lower material frame 244 during the reset process, ensuring that only one aluminum tube enters the subsequent process at a time, thereby improving the stability and consistency of the feeding rhythm.

[0053] Understandably, when the abutment frame 2231 is driven by the swing seat 2223, one end of the abutment frame 2231 swings downward and presses the linkage plate 242, forcing the linkage plate 242 to swing downward as well, thereby receiving the aluminum tube on the unloading plate 232. Subsequently, when the abutment frame 2231 leaves the linkage plate 242, the movable plate 243 automatically resets under the action of the elastic element and pushes the aluminum tube onto the step plate 241, thereby pushing the aluminum tube towards the lower material frame 244 and storing it in the unloading frame 244 for convenient subsequent feeding processing, so as to complete the single quantitative feeding and thus realize the automatic and orderly supply of aluminum tubes. In addition, after the abutment frame 2231 is reset, since the abutment frame 2231 abuts against the unloading port of the unloading frame 244, the abutment frame 2231 can also block the unloading port of the unloading frame 244, preventing the aluminum alloy forging (aluminum tube) to be expanded located in the unloading frame 244 from falling out of the unloading frame 244.

[0054] When the swing seat 2223 drives the abutment frame 2231 to perform the next swing action, the above-mentioned process of feeding, receiving and pushing, and sealing the unloading port will be repeated, realizing the continuous and cyclical quantitative feeding operation of aluminum alloy forgings. There is no need for operators to manually place aluminum tubes one by one, which reduces the intensity of manual labor and effectively improves the safety and efficiency of feeding operations.

[0055] In another embodiment of this application, such as Figure 8As shown, the transmission between the linkage plate 242 and the abutment frame 2231 described in the above embodiments can be accomplished by rope transmission, but the trajectory of movement is opposite to the transmission trajectory described in the above embodiments. For example, it can be achieved using a rope (not specifically marked in the figure) and a guide wheel (not specifically marked in the figure). Specifically, the guide wheel is rotatably mounted on the storage box 231, and the vertical height of the guide wheel relative to the ground is higher than the height of the abutment frame 2231. One end of the rope is fixedly connected to the abutment frame 2231, and the other end passes around the guide wheel and is fixedly connected to the linkage plate 242. When the abutment frame 2231 swings down, the linkage plate 242 rises under the pull of the rope, and the movable plate 243 drives the aluminum tube to move onto the step plate 241. When the abutment frame 2231 resets, the movable plate 243 descends under its own gravity, thereby realizing the feeding of subsequent aluminum tubes.

[0056] It is understandable that by adopting a rope-driven drive method, not only can energy loss be saved (effort is saved) during feeding, but there is also no need to install an elastic element for resetting. Compared with the previous implementation method, not only is energy loss reduced, but the manufacturing cost of the entire feeding equipment is also reduced.

[0057] It should also be noted that the vertical height of the movable plate 243 described in this embodiment relative to the ground at its initial position is lower than the height of the adjacent step plate 241.

[0058] The above-described implementation method enables automatic feeding and precise positioning of aluminum tubes, reduces manual intervention and labor intensity, and thus improves the production efficiency of hole expansion processing.

[0059] In one embodiment of this application, such as Figure 2 As shown, the hole enlarging mechanism 1 may include a base 11, a hydraulic unit 12, a mounting base 13, a pressure roller 14, and a support assembly 15.

[0060] As a possible scenario, in order to facilitate the unloading of the aluminum tube after the hole enlargement is completed, a conveyor belt (not shown in the figure) can be installed at the bottom of the base 11 to realize the automatic unloading and conveying of the aluminum tube after the hole enlargement is completed.

[0061] It should be noted that the hydraulic unit 12 described in the above embodiments can be a hydraulic cylinder.

[0062] It should be noted that the pressure roller 14 and the support assembly 15 described in the above embodiments are both driven by a geared motor (not shown in the figure) to achieve rolling and expanding of the aluminum tube. The pressure roller 14 has a limiting groove in the middle for limiting the aluminum tube, so as to prevent the aluminum tube from detaching from the pressure roller 14 during the rolling process.

[0063] The hydraulic unit 12 is mounted on the base 11, and the extended end of the hydraulic unit 12 is connected to the mounting base 13. The pressure roller 14 is rotatably mounted on the bottom end of the mounting base 13, and the support assembly 15 is mounted on the base 11.

[0064] Understandably, the hydraulic unit 12, mounting base 13, pressure roller 14 and support assembly 15 are installed under the action of the base 11. Then, the mounting base 13 is driven under the action of the hydraulic unit 12, the aluminum tube is positioned and supported under the action of the support assembly 15, and the aluminum tube on the support assembly 15 is rolled and enlarged under the rotation of the pressure roller 14.

[0065] Specifically, such as Figure 3 As shown, the support assembly 15 may include a fixed base 151, a rotating ring 152, a limiting ring 153, multiple sets of meshing teeth 154, a cross-shaped locking block 155, a support roller 156, a drive component 157, and an auxiliary component 158.

[0066] It should be noted that aluminum tubes with different apertures can be adapted by replacing the fixed seat 151, rotating ring 152, limiting ring 153, multiple sets of meshing teeth 154, cross block 155 and support roller 156.

[0067] The fixed seat 151 is mounted on the base 11, the rotating ring 152 is rotatably mounted on the fixed seat 151 through the limiting ring 153, multiple sets of meshing teeth 154 are equidistantly mounted on the outer circumferential surface of the rotating ring 152, the cross block 155 is engaged in the middle of the rotating ring 152, the support roller 156 is connected to the cross block 155, the driving component 157 is installed inside the base 11 and meshes with the meshing teeth 154, and the auxiliary component 158 ​​is mounted on the base 11.

[0068] Understandably, the rotating ring 152 is installed under the action of the fixed seat 151, and the rotating ring 152 is limited on the fixed seat 151 by the limiting ring 153 to prevent the rotating ring 152 from falling off the fixed seat 151 during rotation. Then, driven by the driving component 157, the rotating ring 152 and the meshing teeth 154 rotate on the fixed seat 151. When the rotating ring 152 rotates, it drives the support roller 156 to rotate together through the cross block 155, thereby cooperating with the pressure roller 14 to complete the rolling and pore-expanding process on the aluminum tube on the support roller 156. After the pore-expanding is completed, the tube is collected... The shrinking component 3 drives the support roller 156 to detach from the rotating ring 152, while the aluminum tube abuts against the fixed seat 151 and falls off the support roller 156 to the bottom of the base 11, facilitating the unloading of the aluminum tube after the hole is enlarged. Subsequently, the shrinking component 3 drives the cross block 155 and the support roller 156 to re-enter the rotating ring 152. At the same time, the auxiliary component 158 ​​descends to facilitate the subsequent feeding of the aluminum tube. After feeding, the auxiliary component 158 ​​rises to support one end of the support roller 156, preventing uneven force on the support roller 156 during the rolling and enlarging process, which could cause the support roller 156 to tilt.

[0069] To further clarify the above embodiment, in one embodiment of this application, the drive component 157 may include a transmission rod 1571 and a drive gear 1572.

[0070] It should be noted that the end of the transmission rod 1571, which is away from the drive gear 1572, described in the above embodiment passes through the base 11, so as to facilitate connection with the geared motor (not shown in the figure).

[0071] The transmission rod 1571 is rotatably mounted on the base 11, and the drive gear 1572 is connected to the transmission rod 1571.

[0072] Understandably, the transmission rod 1571 drives the drive gear 1572 to rotate under the drive of the geared motor. The drive gear 1572 meshes with multiple sets of meshing teeth 154 to drive the rotation ring 152 to rotate at a uniform speed, ensuring that the aluminum tube is subjected to uniform rolling pressure during the hole expansion process, and improving the consistency of the dimensions and processing quality after hole expansion.

[0073] To further clarify the above embodiment, in one embodiment of this application, the auxiliary component 158 ​​may include a hydraulic rod 1581 and an auxiliary frame 1582.

[0074] It should be noted that the auxiliary frame 1582 described in the above embodiments can be detached from the hydraulic rod 1581 to adapt to the end support requirements of support rollers 156 of different diameters.

[0075] Hydraulic rod 1581 is mounted on base 11, and auxiliary frame 1582 is mounted on the extended end of hydraulic rod 1581. The top of auxiliary frame 1582 is provided with an arc-shaped groove that matches the support roller 156.

[0076] Understandably, the hydraulic rod 1581 can drive the auxiliary frame 1582 to rise and fall vertically. When the aluminum tube to be processed needs to be placed in, the hydraulic rod 1581 drives the auxiliary frame 1582 to fall, so as to avoid blocking the aluminum tube from entering the hole-expanding position. After the aluminum tube is in place, the hydraulic rod 1581 drives the auxiliary frame 1582 to rise, so that the arc groove fits and supports the end of the support roller 156, thereby improving the structural stability of the support roller 156 during the hole-expanding process, preventing the aluminum tube from shaking and shifting during processing, and ensuring the accuracy of the hole-expanding process.

[0077] Specifically, the aluminum alloy forging reaming and feeding device provided in this application can be used for automatic feeding and positioning operations during the reaming process of aluminum alloy forgings. In actual operation, the relevant personnel first store the cut aluminum tube in the storage box 231, and the aluminum tube rolls towards the lower material frame 244 under the guidance of the unloading plate 232. The reciprocating motor 2221 of the feeding component 22 is started, and the reciprocating motor 2221 drives the swing seat 2223 to swing back and forth through the power rod 2222. The swing seat 2223 drives the storage rack 2232 and the abutment frame 2231 to swing synchronously.

[0078] When the abutment frame 2231 swings downward, the pressing linkage plate 242 drives the movable plate 243 to move downward, causing an aluminum tube in the unloading frame 244 to fall into the placement slot of the storage rack 2232. Subsequently, the reciprocating motor 2221 drives in the reverse direction, and the swing seat 2223 drives the abutment frame 2231 to swing upward and reset. During the reset process, the arc-shaped end of the abutment frame 2231 disengages from the linkage plate 242, and the movable plate 243 automatically resets under the action of an elastic element (e.g., a spring), pushing the subsequent aluminum tubes towards the unloading frame 244. After the abutment frame 2231 raises the aluminum tube to the same height as the support component 15 of the hole-expanding mechanism 1, the electric push rod 2224 is activated. The electric push rod 2224 pushes the top plate 2225 forward, pushing the aluminum tube from the placement slot of the abutment frame 2231 into the support roller 156, completing the automatic feeding.

[0079] After the aluminum tube is in place, the reaming mechanism 1 is activated. The hydraulic unit 12 pushes the mounting base 13 and the pressure roller 14 downward to the working position. The reduction motor drives the rotating ring 152 to rotate through the transmission rod 1571 and the drive gear 1572. The rotating ring 152 drives the support roller 156 to rotate through the cross block 155. The aluminum tube is rolled and expanded between the pressure roller 14 and the support roller 156. During the reaming process, the hydraulic rod 1581 of the auxiliary component 158 ​​drives the auxiliary frame 1582 to rise, so that the arc groove at the top of the auxiliary frame 1582 fits and supports the end of the support roller 156, enhancing the structural stability of the support roller 156.

[0080] After the reaming is completed, the hydraulic unit 12 drives the pressure roller 14 to rise and reset. The shrinking assembly 3 actuates, causing the cross block 155 and support roller 156 to be pulled out of the rotating ring 152. After the reamed aluminum tube comes into contact with the fixed seat 151, it detaches from the support roller 156 and falls into the collection area at the bottom of the base 11 to complete the unloading. Subsequently, the shrinking assembly 3 drives the cross block 155 and support roller 156 back into the rotating ring 152, and the hydraulic rod 1581 drives the auxiliary frame 1582 to descend, waiting for the next loading. Through the above process, automatic loading, automatic reaming, and automatic unloading of aluminum tubes are achieved, significantly reducing manual intervention and improving the production efficiency and automation level of the reaming process.

[0081] In summary, the aluminum alloy forging hole-expanding feeding device of this application embodiment can realize automatic feeding and precise positioning of aluminum tubes, reduce manual intervention and labor intensity, and thus improve the production efficiency of hole-expanding processing.
