Description

Technical Field

[0001] This application relates to the field of boom processing technology, and in particular to boom processing apparatus and methods. Background Technology

[0002] A ceiling fan light is an appliance that combines the functions of a chandelier and a ceiling fan, providing multiple benefits such as lighting, ventilation, and decoration. The hanging component of a typical ceiling fan light on the market mainly consists of six parts: a hanging rod, a R-pin, a latch, a hanging ball, an I-beam frame, and a hanging ball screw. During assembly, the upper end of the hanging rod is first inserted into the hanging ball, and the hanging ball screw is tightened. Then, the latch is passed through the corresponding holes in the hanging rod and the hanging ball, and the R-pin is engaged. Finally, the hanging ball at the upper end of the hanging rod is placed into the slot of the I-beam frame, thus detachably fixing the hanging rod and the I-beam frame.

[0003] Currently, the processing technology for fan light hangers typically involves two main steps: edge folding and double-ear expansion. These two steps are traditionally performed separately, leading to production efficiency being affected by factors such as transport and positioning, thus impacting the hanger processing efficiency. Furthermore, these two independent processing steps require separate equipment and operations. This approach not only occupies space but also has a long processing cycle and high costs; therefore, further improvements are warranted. Summary of the Invention

[0004] To improve the processing efficiency of the suspension rod manufacturing process, this application provides a suspension rod processing apparatus and method.

[0005] The hanging rod processing device and method provided in this application adopt the following technical solution: The hanging rod processing device includes a worktable, on which an upper mold base with an upper mold core, a lower mold base with a lower mold core, and an impact mechanism are provided. The lower mold base is located at the top of the worktable, and the upper mold base is located above the lower mold base. The upper mold core and the lower mold core are combined to form a receiving cavity. A hollow workpiece is placed in the receiving cavity. The impact mechanism is located on the side of the opening of the lower mold core of the lower mold base, and the impact mechanism and the lower mold base are located on the same horizontal line. A support base is provided on the worktable on one side of the lower die base, and a first driving mechanism is provided on the support base. The first driving mechanism is connected to the upper die base. A second driving mechanism is provided on the worktable on one side of the impact mechanism. The impact mechanism includes a connecting column and a double-eared folding piece connected in sequence. The double-eared folding piece is installed on the side of the connecting column near the lower die base. The connecting column is connected to the second driving mechanism. The double-eared folding piece can be inserted into the workpiece. The receiving cavity contains a workpiece fixed for processing into a lifting rod; The first drive mechanism is used to control the upper mold base to perform up and down lifting movements; The second drive mechanism is used to control the impact mechanism to perform forward and backward horizontal movements; The double-eared folding piece is used to simultaneously perform impact folding and double-ear processing on the workpiece; By adopting the above technical solution, the first drive mechanism on the worktable is activated to separate the upper mold base from the lower mold base. Then, the workpiece is placed into the lower mold core. The first drive mechanism is then activated to combine the upper mold base and the lower mold assembly. The second drive mechanism is activated to drive the connecting column to move toward the workpiece, so that the double-ear folding parts on the connecting column can simultaneously fold and expand the double ears of the workpiece. This simplifies the production process, eliminates the need for additional processing, and improves the production efficiency of the hanger. Since it is a one-time processing, it enhances the consistency of product quality and reduces production costs.

[0006] Optionally, the double-ear folded edge component includes a folded edge post and a core head, wherein the core head is mounted on the side of the folded edge post near the receiving cavity; The folded column is cylindrical, and its axis coincides with that of the workpiece in the receiving cavity. The cross-sectional area of ​​the folded column is larger than that of the workpiece, and the radius of the cross-section of the folded column is in the range of 72~78mm.

[0007] By adopting the above technical solution, the cross-sectional area of ​​the folding column is larger than the cross-sectional area of ​​the workpiece, so that when the folding column impacts the workpiece, the workpiece can make complete contact with the folding column, allowing the folding column to better perform folding processing on the workpiece.

[0008] Optionally, the core head includes a small diameter section, a transition section, and a large diameter section, wherein the transition section connects the small diameter section and the large diameter section, and the axes of the small diameter section, the transition section, and the large diameter section coincide. A stabilizing protrusion is provided on the side of the small diameter section near the receiving cavity. Shaping ears are provided on both sides of the small diameter section, the transition section and the large diameter section along their length direction. The outer periphery of the shaping ears is inclined. The ends of the shaping ears on both sides near the receiving cavity are respectively connected to the ends of the stabilizing protrusion away from the receiving cavity. The stabilizing protrusion and the shaping ears are integrally formed.

[0009] By adopting the above technical solution, this setup can better form the suspension rod.

[0010] Optionally, the small diameter section and the transition section are frustum-shaped, the large diameter section is cylindrical, the circumferential slope of the small diameter section and the transition section gradually increases from the small diameter section to the transition section, and the radius of the large diameter section is greater than the maximum radius of the transition section.

[0011] By adopting the above technical solution, during processing, the small diameter section determines the shape and inner diameter of the rod. When the core head tends to move in the pulling direction, due to the presence of the large diameter section and the transition section, and the small diameter of the rod after forming, the transition section and the large diameter section will be stuck at the already formed rod folded lug and will not continue to move forward, ensuring the insertion depth of the core head.

[0012] Optionally, the stabilizing protrusion near the receiving cavity includes a first horizontal portion and a first arc-shaped portion. The first horizontal portion is centrally located, and there are two sets of the first arc-shaped portion. The two sets of the first arc-shaped portion are respectively located on both sides of the first horizontal portion, and the connection between the two sets of the first arc-shaped portion and the first horizontal portion is smoothly transitioned. The arc range of the first arc-shaped portion is 2.8~2.9 rad.

[0013] By adopting the above technical solution, this setup can better form the suspension rod.

[0014] Optionally, the small diameter section, the transition section, and the large diameter section are also provided with connecting blocks on both sides along their length direction. The end of the connecting block near the receiving cavity is connected to the end of the shaping ear away from the receiving cavity, and the connecting block, the shaping ear, and the stabilizing protrusion are all integrally formed.

[0015] By adopting the above technical solution, this setting can make the ear-shaped structure more stable.

[0016] Optionally, the outer periphery of the shaping ear is inclined outward from one end of the stabilizing protrusion to one end of the connecting block, and the inclination angle of the shaping ear is in the range of 14~16°.

[0017] By adopting the above technical solution, this setup allows for more accurate molding of the required suspension rod.

[0018] Optionally, a shelf is provided on the side of the worktable away from the support base, and the length of the shelf is the same as the length of the lower mold base.

[0019] By adopting the above technical solution, a special shelf is set up to place the processed lifting rods, providing a designated area for storing the lifting rods, which facilitates subsequent management and retrieval, and reduces damage or deformation caused by improper stacking.

[0020] Secondly, this application provides a method for processing suspension rods, which adopts the following technical solution: A method for processing a suspension rod, based on the suspension rod technician device described above, includes the following specific steps: S1: Select the workpiece and, according to customer requirements, use a cutting machine to cut the workpiece to be processed into a workpiece of appropriate length; S2: Preliminary processing of the workpiece. The workpiece is straightened using a straightening machine to improve its flatness and ensure the straightness of the suspension rod. S3: Apply oil to the workpiece, applying oil to the inside of the machined area of ​​the workpiece; S4: Fix the workpiece, start the first drive mechanism, use the first drive mechanism to separate the upper mold base from the lower mold base, place the workpiece into the lower mold core in the lower mold base, and place the part of the workpiece to be processed outside the lower mold base. Then start the first drive mechanism to move the upper mold base onto the lower mold base, so that the upper mold core and the lower mold core form a receiving cavity, and the workpiece is fixed in the receiving cavity. S5: Workpiece processing: Start the second drive mechanism. The second drive mechanism drives the connecting column to move and impact the workpiece at the receiving cavity position, so that the folding column on the connecting column and the core head simultaneously perform folding and double ear expansion processing on the workpiece outside the lower mold base.

[0021] S6: Workpiece demolding: Start the second drive mechanism, which drives the connecting column away from the workpiece in the receiving cavity. The workpiece and the folding column separate from the core head. Then start the first drive mechanism to drive the upper mold base to rise away from the lower mold base. Finally, remove the processed lifting rod and demold.

[0022] Optionally, in step S6, after demolding, the hanger rod needs to undergo heat treatment, surface cleaning, and flaw detection. After the final inspection is completed and no errors are found, it is cleaned, packaged, and put into storage.

[0023] By adopting the above technical solution, the processed hanger rod is heat-treated to eliminate the internal stress generated during the processing, thereby improving the stability and reliability of the hanger rod.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Start the first drive mechanism on the worktable to separate the upper mold base from the lower mold base. Then place the workpiece into the lower mold core. Start the first drive mechanism again to combine the upper mold base and the lower mold assembly. Start the second drive mechanism to drive the connecting column to move toward the workpiece. This allows the double-ear folding parts on the connecting column to simultaneously fold and expand the double ears of the workpiece, simplifying the production process and eliminating the need for additional processing. This improves the production efficiency of the hanger. Since it is a one-time processing, it enhances the consistency of product quality and reduces production costs. 2. The cross-sectional area of ​​the folding post is larger than that of the workpiece, so that when the folding post impacts the workpiece, the workpiece can make complete contact with the folding post, allowing the folding post to better perform folding processing on the workpiece. 3. During processing, the small diameter section determines the shape and inner diameter of the rod. When the core head tends to move in the pulling direction, due to the presence of the large diameter section and the transition section, and the small diameter of the rod after forming, the transition section and the large diameter section will be stuck at the already formed rod folded lug and will not continue to move forward, ensuring the insertion depth of the core head.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a device for processing suspension rods.

[0033] Reference Figure 1 , 2 The boom processing device includes a worktable 100. The worktable 100 has an upper mold base 2 with a semi-circular upper mold core, a lower mold base 3 with a semi-circular lower mold core, and an impact mechanism 7 on its top surface. The upper mold base 2 is located on top of the lower mold base 3 and can be connected to the lower mold base 3. After the upper mold base 2 and the lower mold base 3 are connected, the upper mold core and the lower mold core merge to form a receiving cavity 4 with a circular cross-section. During processing, the hollow workpiece 1 is loaded into the receiving cavity 4. The impact mechanism 7 is located on the side of the lower mold core opening along its length in the lower mold base 3, and the impact mechanism 7 and the lower mold base 3 are located on the same horizontal line to ensure that the impact mechanism 7 can perform impact processing on the workpiece 1 in the lower mold base 3. A support base 5 is provided on the top surface of the worktable 100 along the length of the lower mold base 3. A first drive mechanism 6 is provided on the support base 5. The first drive mechanism 6 is located above the upper mold base 2 and is connected to the top of the upper mold base 2 so that the upper mold base 2 can move up and down. A second drive mechanism 8 is provided on the top surface of the worktable 100 along the side of the impact mechanism 7. The second drive mechanism 8 is parallel to the impact mechanism 7 and is connected to the impact mechanism 7 so that the impact mechanism 7 can move back and forth in the direction of the lower mold base 3. The impact mechanism 7 includes a connecting column 71 and a double-eared folding piece 72. The connecting column 71 is cylindrical, and the double-eared folding piece 72 is installed on the side of the connecting column 71 along its length direction near the lower die base 3. The side of the connecting column 71 near the second drive mechanism 8 is connected to the second drive mechanism 8. The second drive mechanism 8 drives the connecting column 71 to extend and retract towards the lower die base 3, thereby allowing the double-eared folding piece 72 to be inserted into the workpiece 1 in the receiving cavity 4, realizing the folding and double-earing processing of the workpiece.

[0034] In actual use, the first drive mechanism 6 on the workbench 100 is activated to separate the upper mold base 2 from the lower mold base 3. Then, the workpiece 1 is placed into the lower mold core. The first drive mechanism 6 is then activated to combine the upper mold base 2 with the lower mold assembly. The second drive mechanism 8 is activated to drive the connecting column 71 to move toward the workpiece 1, so that the double-ear folding part 72 on the connecting column 71 simultaneously performs folding and double-ear expansion processing on the workpiece 1. This simplifies the production process, eliminates the need for additional processing, and improves the production efficiency of the hanger. Since it is a one-time processing and forming process, it enhances the consistency of product quality and reduces production costs.

[0035] refer to Figure 2 Specifically, in this embodiment, a shelf 9 is provided on the side of the upper surface of the workbench 100 away from the support base 5. The length of the shelf 9 is the same as that of the lower mold base 3. An intercepting plate is provided on the side of the shelf 9 away from the workbench 100. The bottom of the intercepting plate is perpendicular to the top of the shelf 9, and the top of the intercepting plate is chamfered.

[0036] In actual use, a special shelf 9 is set up to place the processed lifting rods, providing a designated area for storing the lifting rods, which facilitates subsequent management and retrieval, and reduces damage or deformation caused by improper stacking.

[0037] refer to Figure 2 , 34. Specifically, in this embodiment, the double-ear folding component 72 includes a folding post 721 and a core head 722. The core head 722 is installed on the side of the folding post 721 near the receiving cavity 4. The folding post 721 is cylindrical, and the axes of the folding post 721, the core head 722, and the workpiece 1 in the receiving cavity 4 coincide. The cross-sectional area of ​​the folding post 721 is larger than the cross-sectional area of ​​the workpiece 1. The radius of the cross-section of the folding post 721 is 72~78mm, and in this embodiment, it is 75mm.

[0038] In actual use, the cross-sectional area of ​​the folding post 721 is larger than that of the workpiece 1, so that when the folding post 721 impacts the workpiece 1, the core head 722 is inserted into the workpiece 1 for expansion, and the workpiece 1 can make complete contact with the folding post 721, so that the folding post 721 can better perform folding processing on the workpiece 1.

[0039] refer to Figure 3 Specifically, in this embodiment, the core tip 722 includes a small diameter section 7221, a transition section 7222, and a large diameter section 7223. The transition section 7222 connects the small diameter section 7221 and the large diameter section 7223, and the axes of the small diameter section 7221, the transition section 7222, and the large diameter section 7223 coincide. The small diameter section 7221 and the transition section 7222 are both frustum-shaped, and the large diameter section 7223 is cylindrical. The circumferential slope of the small diameter section 7221 and the transition section 7222 gradually increases from the small diameter section 7221 to the transition section 7222. The radius of the large diameter section 7223 is greater than the maximum radius of the transition section 7222, and the radius of the large diameter section 7223 is 95mm. In actual use, the small diameter section 7221 determines the shape and inner diameter of the rod. When the core head 722 tends to move in the pulling direction, due to the presence of the large diameter section 7223 and the transition section 7222, and the small diameter of the rod after forming, the transition section 7222 and the large diameter section 7223 will be stuck at the already formed rod fold and will not continue to move forward, ensuring the insertion depth of the core head 722.

[0040] refer to Figure 2 , 34. Specifically, in this embodiment, a stabilizing protrusion 723 is vertically arranged on the side of the small-diameter section 7221 near the receiving cavity 4. Shaping ears 724 and connecting blocks 725 are arranged on both sides of the small-diameter section 7221, the transition section 7222, and the large-diameter section 7223 along their length direction. The ends of the shaping ears 724 near the receiving cavity 4 are respectively connected to the ends of the stabilizing protrusion 723 away from the receiving cavity 4. The ends of the connecting blocks 725 near the receiving cavity 4 are respectively connected to the ends of the shaping ears 724 away from the receiving cavity 4. The connecting blocks 725, shaping ears 724, and stabilizing protrusion 723 are all integrally formed. The outer periphery of the shaping ears 724 is inclined. The outer periphery of the shaping ear 724 is inclined outward from one end of the stabilizing protrusion 723 to one end of the connecting block 725. The inclination angle of the shaping ear 724 is in the range of 14~16°, and in this embodiment it is 14.01°. In the actual processing, so that the stabilizing protrusion 723 can be inserted into the workpiece 1, the shaping ears 724 located on both sides of the stabilizing protrusion 723 are inserted into the workpiece 1. The inner sidewall of the workpiece 1 contacts the outer sidewall of the shaping ear 724, and the shaping ear 724 is expanded into a double ear, so that the core head 722 can better process the workpiece 1 into a hanging rod.

[0041] refer to Figure 4 Specifically, in this embodiment, the stabilizing protrusion 723 near the receiving cavity 4 includes a first horizontal portion 7231 and a first arc-shaped portion 7232. The first horizontal portion 7231 is centrally located, and there are two sets of the first arc-shaped portion 7232. The two sets of the first arc-shaped portion 7232 are respectively located on both sides of the first horizontal portion 7231, and the connection between the two sets of the first arc-shaped portion 7232 and the first horizontal portion 7231 is smoothly transitioned. The arc range of the first arc-shaped portion 7232 is 2.8~2.9 rad, and in this embodiment it is specifically 2.89 rad.

[0042] In actual processing, on the one hand, the two sets of first arc-shaped portions 7232 allow the stabilizing protrusions 723 to be better inserted into the workpiece 1. On the other hand, the stabilizing protrusions 723 are set at the front end of the shaping ears 724 on both sides. First, the stabilizing protrusions 723 can serve as positioning elements, preferentially connecting with the inside of the workpiece 1 to ensure the accuracy and stability of the position during the impact. Moreover, the presence of the stabilizing protrusions 723 can increase the local strength of the small diameter section 7221 as the head, making the shaping ears 724 connected to the stabilizing protrusions 723 stronger. During the impact, the stabilizing protrusions 723 improve the force distribution of the shaping ears 724, reduce stress concentration, and increase the service life of the shaping ears 724.

[0043] refer to Figure 2 , 5Specifically, in this embodiment, in order to ensure that the upper mold base 2 and the lower mold base 3 do not affect the forming of the double ears of the workpiece 1 during the double ear expansion process in the receiving cavity 4, the top of the upper mold base 2 is provided at the end of the upper mold base 2 near the core head 722 and the bottom of the lower mold base 3 is provided at the end of the lower mold base 3 near the core head 722. When the core head 722 is inserted into the workpiece 1 for processing, the double ear position of the workpiece 1 is located at the position of the clearance opening 21.

[0044] refer to Figure 1 , 2 Specifically, in this embodiment, the first driving mechanism 6 includes a driving support plate 61. The driving support plate 61 is located on the top of the support base 5 near the lower mold base 3 and is parallel to the top of the support base 5. The support base 5 is provided with three sets of lifting hydraulic cylinders 62 at intervals along its length. Each lifting hydraulic cylinder 62 has a fixed seat 63 at its bottom movable end. The top of the fixed seat 63 is connected to the bottom of the lifting hydraulic cylinder 62, and the bottom of the fixed seat 63 is connected to the top of the upper mold base 2, so that when the lifting hydraulic cylinder 62 drives the fixed seat 63 to move up and down, it simultaneously drives the upper mold base 2 to move up and down.

[0045] refer to Figure 1 , 2 Specifically, in this embodiment, the second driving mechanism 8 includes a driving support 81, which is installed on the top surface of the workbench 100. A telescopic hydraulic cylinder 82 is installed on the driving support 81. A fixed frame 83 is provided on the movable end of the telescopic hydraulic cylinder 82 near the lower mold base 3. One side of the fixed frame 83 is connected to the movable end of the telescopic hydraulic cylinder 82, and the other end of the fixed frame 83 is fixedly connected to the connecting column 71. In addition, a guide rail 84 is provided on the top surface of the workbench 100 along its length, and a guide slider 85 is provided on the connecting column 71 along its length. The guide slider 85 is slidably disposed in the guide rail 84, so that when the connecting column 71 moves in extension and retraction under the drive of the telescopic hydraulic cylinder 82, the guide slider 85 at the bottom of the connecting column 71 cooperates with the guide rail 84, making the accuracy of the connecting column 71 during the movement more accurate.

[0046] The implementation principle of the boom processing device in this application embodiment is as follows: the first drive mechanism 6 on the workbench 100 is started to separate the upper mold base 2 and the lower mold base 3. Then, the workpiece 1 is placed in the lower mold core. The first drive mechanism 6 is started again to combine the upper mold base 2 and the lower mold assembly. Then, the second drive mechanism 8 is started to drive the connecting column 71 to move toward the workpiece 1, so that the double-ear folding part 72 on the connecting column 71 simultaneously performs folding and double-ear expansion processing on the workpiece 1. The core head 722 is first inserted into the workpiece 1. The shaping ear 724 on the core head 722 expands the double ears of the workpiece 1 from the inside to the outside. At the same time, the folding column 721 contacts the workpiece 1 and squeezes and folds the workpiece 1, thereby completing the processing.

[0047] This application also discloses a method for processing suspension rods.

[0048] The method for processing a suspension rod, based on the aforementioned suspension rod processing device, includes the following steps: S1: Select workpiece 1, and according to customer requirements, use a cutting machine to cut the workpiece 1 to a suitable length. S2: Initial processing of workpiece 1. The workpiece 1 is straightened using a straightening machine to improve its flatness and ensure the straightness of the suspension rod. S3: Apply oil to workpiece 1, and apply oil to the inside of the machined area of ​​workpiece 1; S4: Fix workpiece 1, start the first drive mechanism 6, use the first drive mechanism 6 to separate the upper mold base 2 and the lower mold base 3, place workpiece 1 into the lower mold core in the lower mold base 3, and place the part of workpiece 1 to be processed outside the lower mold base 3. Then start the first drive mechanism 6 to move the upper mold base 2 onto the lower mold base 3, so that the upper mold core and the lower mold core form a receiving cavity 4, and the workpiece 1 is fixed in the receiving cavity 4. S5: Workpiece 1 processing: Start the second drive mechanism 8. The second drive mechanism 8 drives the connecting column 71 to move and impact the workpiece 1 at the position of the receiving cavity 4, so that the folding column 721 and the core head 722 on the connecting column 71 simultaneously perform folding and double ear expansion processing on the workpiece 1 outside the lower mold base 3.

[0049] S6: Demolding of workpiece 1: Start the second drive mechanism 8. The second drive mechanism 8 drives the connecting column 71 away from the position of workpiece 1 in the receiving cavity 4. Workpiece 1 and the folding column 721 separate from the core head 722. Then start the first drive mechanism 6 to drive the upper mold base 2 to rise away from the lower mold base 3. Finally, the processed lifting rod is taken out and demolded.

[0050] In step S6, after demolding, the rod needs to undergo heat treatment, surface cleaning, and flaw detection. After the final inspection is completed and no errors are found, it is cleaned, packaged, and put into storage.

[0051] In the actual processing, the processed hanger rod is heat-treated to eliminate the internal stress generated during processing, thereby improving the stability and reliability of the hanger rod.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
