Description

Technical Field

[0001] This invention relates to the field of aluminum alloy ladder processing technology, specifically a lightweight, high-strength aluminum alloy ladder extrusion forming device and its processing method. Background Technology

[0002] Aluminum alloy ladders are modern climbing and access tools primarily used for firefighting and rescue operations. Their design combines modern technology and materials science, using aluminum alloy as the main material, offering advantages such as lightweight, high strength, and corrosion resistance. Aluminum alloy ladders have a wide range of applications, not limited to firefighting and rescue, but also including high-altitude operations, equipment installation, landscaping, and many other situations. During the manufacturing process, pre-cut, equidistant climbing crossbars are often joined with long, thick bars on both sides, and then extruded to secure the crossbars to the long, thick bars, thus shaping the ladder.

[0003] Currently, during the extrusion molding process of aluminum alloy ladders, the surfaces of the cut equidistant climbing crossbars often have some cutting debris attached. If this debris is not cleaned in time, it can easily cause insufficient and tight adhesion between the cut equidistant climbing crossbars and the long, thick bars on both sides during extrusion, affecting the tightness of the connection, leading to poor quality, and making it prone to loosening during long-term use, affecting the stability of use. Moreover, the extrusion friction of debris can also cause wear on the surface of the extrusion tool, increasing the wear and replacement costs of the extrusion tool. Therefore, this invention proposes a lightweight, high-strength aluminum alloy ladder extrusion molding device and its processing method. Summary of the Invention

[0015] Preferably, a processing method for a lightweight, high-strength aluminum alloy ladder extrusion forming device includes the following steps:

[0016] S1. First, place the ladder blank on the top of the fixed frame plate and operate the telescopic support mechanism to support and limit the two ends of the ladder blank. Then, the moving feeding mechanism drives the climbing crossbar on one side of the ladder blank to the fixed limiting mechanism. During the movement, the debris on the surface of the ladder blank is shaken off and collected into the collection frame by the filter screen.

[0020] 1. The present invention can drive the ladder blank to be transported in a stable, intermittent and orderly manner through the set telescopic support mechanism and the moving feeding mechanism, so as to facilitate the subsequent extrusion molding of the ladder blank. At the same time, during the transport process, the vibration generated when it comes into contact with the filter screen plate is used to shake off and collect the debris attached to the surface of the ladder blank in conjunction with the collection frame.

[0021] 2. This invention, through the combination of a mobile feeding mechanism, a cleaning and inspection mechanism, and a vibration mechanism, enables the cleaning of debris and defect detection of the extrusion seat in the extrusion mechanism during the conveying process. This avoids debris from being mixed in during the extrusion friction process and causing wear on the surface of the extrusion seat, thereby reducing the wear and replacement cost of the extrusion seat. It also avoids insufficient tightness and fit during extrusion due to the influence of debris, ensuring the tightness and fixation of the connection after extrusion molding.

[0022] 3. The present invention, through the combination of a fixed limiting mechanism and a lifting suction mechanism with an extrusion mechanism, can further limit and fix the part of the ladder blank to be extruded. At the same time, during the pressing and fixing process, the debris on the convex plate is extracted and cleaned so that the debris can fall fully into the collection frame, thereby enhancing the debris cleaning and collection effect and realizing stable extrusion molding of the ladder blank.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figure 1 - Figure 9 As shown, a lightweight, high-strength aluminum alloy ladder extrusion forming device and its processing method include a fixed frame plate 1, a collection frame 2 fixedly connected to the bottom end of the fixed frame plate 1, and a sealing plate 3 connected to one end of the collection frame 2 by bolts. A filter screen plate 4 is embedded and connected to the inner bottom end of the fixed frame plate 1. A ladder blank 13 is provided on the top of the fixed frame plate 1. A telescopic support mechanism 5 is provided between the top of the filter screen plate 4 and the outer wall of the ladder blank 13. A support frame 6 is fixedly connected to the top of the filter screen plate 4. A pair of moving feeding mechanisms 7 are provided on the outer wall of the fixed frame plate 1. A fixed limiting mechanism 8 is provided between the top of the fixed frame plate 1 and the outer wall of the ladder blank 13. An extrusion mechanism 9 is provided on the outer wall of the fixed frame plate 1.

[0036] During use, the filter screen 4 filters the debris falling from the ladder blank 13 and collects it into the collection frame 2. The detachable sealing plate 3 can clean the debris collected in the collection frame 2.

[0037] like Figure 1 - Figure 4 As shown, the telescopic support mechanism 5 includes a pair of movable sleeves 501. A connecting frame plate 502 is fixedly connected to the top of each pair of movable sleeves 501, and a pair of connecting frame plates 502 is also fixedly connected to the top of the filter screen plate 4. T-shaped rods 503 are provided inside both pairs of connecting frame plates 502, and round holes are drilled at the inner top of each pair of connecting frame plates 502. The tops of both pairs of T-shaped rods 503 pass through the round holes and extend to their tops. A first spring 504 is sleeved on the outer wall of each pair of T-shaped rods 503, and the top and bottom ends of the first spring 504 are respectively connected to the inner top of the connecting frame plate 502. The bottom of the T-shaped rod 503 is fixedly connected to the top of the pair of T-shaped rods 503 on one side. A top plate 505 is fixedly connected to the top of each pair of top plates 505, and a supporting frame 506 is fixedly connected to the end of each pair of top plates 505 that is close to each other. A side frame 508 is fixedly connected to the top of each pair of T-shaped rods 503 on the other side. The outer wall of the ladder blank 13 contacts the inner walls of the pair of supporting frames 506 and the side frame 508, respectively. Multiple electric suction cups 507 are embedded and connected to the bottom of each pair of supporting frames 506, and the tops of the multiple electric suction cups 507 contact the bottom of the ladder blank 13. Each pair of side frames 508 has a movable fitting plate 5010 inside. Multiple circular springs 509 are fixedly connected between one end of the movable fitting plate 5010 and the inner wall of the side frame 508. The adjacent ends of the pair of movable fitting plates 5010 are in contact with the outer wall of the ladder blank 13. Each pair of moving feeding mechanisms 7 includes an L-shaped plate 701 fixedly connected to the outer wall of the fixed frame plate 1. A pair of pulleys 702 are rotatably connected between the inner wall of the L-shaped plate 701 and the outer wall of the fixed frame plate 1 via bearings and a rotating shaft. A transmission belt 7 is meshed between the outer walls of the pair of pulleys 702. 03. One end of the transmission belt 703 is fixedly connected to one end of the movable sleeve block 501. An auxiliary rod 704 is fixedly connected to the outer wall of the fixed frame plate 1, and the movable sleeve block 501 is sleeved on the outer wall of the auxiliary rod 704. A motor 705 is fixedly connected to the end of the L-shaped plate 701 away from the fixed frame plate 1, and the output end of the motor 705 is fixedly connected to the shaft on the pulley 702 located on one side. A round-headed protruding rod 706 is fixedly connected to the bottom end of the top plate 505, and the bottom end of the round-headed protruding rod 706 contacts the top end of the filter screen plate 4. Multiple pairs of protruding plates 707 are fixedly connected to the top end of the filter screen plate 4.

[0038] In this design, a pair of long, thick rods on the ladder blank 13 are placed on a pair of supporting frames 506 and side frames 508, respectively. On the supporting frames 506, an electric suction cup 507 is driven to adhere and fix the bottom ends of the long, thick rods. Simultaneously, on the side frames 508, a movable bonding plate 5010 and a circular spring 509 are used for limiting and fixing. Then, a motor 705 drives a transmission belt 703 via a pair of pulleys 702, causing the moving sleeve 501 to move horizontally along the auxiliary rod 704, moving the round-headed convex rod 706 from the top of the filter screen plate 4 to the convex plate. On plate 707, as the protruding plate 707 presses up, the ladder blank 13 and a pair of supporting frames 506 and side frames 508 move upward with the assistance of T-shaped rod 503 and first spring 504. As the movement continues, the round-headed protruding rod 706 moves away from the protruding plate 707 and continues to fall back onto the filter screen plate 4, thus driving the ladder blank 13 to perform stable intermittent orderly conveying. The round-headed protruding rod 706 falls back and contacts and collides with the top of the filter screen plate 4, generating vibration and shaking off the debris attached to the surface of the ladder blank 13. After being filtered by the filter screen plate 4, the debris falls into the collection frame 2, thus cleaning and collecting the debris.

[0039] like Figure 1 and Figures 4-5 As shown, the fixed limiting mechanism 8 includes a top-connecting platform 801 fixedly connected to the top of the fixed frame plate 1. A lifting cylinder 802 is embedded in the top of the top of the top-connecting platform 801, and a magnet block 803 is fixedly connected to the output end of the lifting cylinder 802. A movable pressure seat 804 is fixedly connected to the bottom end of the magnet block 803. A rectangular frame 806 is fixedly connected to the top of the filter screen plate 4, and a fixed pressure seat 805 is fixedly connected to the top of the rectangular frame 806. The inner walls of the movable pressure seat 804 and the fixed pressure seat 805 are in contact with the outer wall of the ladder blank 13. A lifting suction mechanism 12 is provided between the inside of the rectangular frame 806 and the magnet block 803.

[0040] During use, after a climbing crossbar on the ladder blank 13 is conveyed into the fixed pressure seat 805, the lifting cylinder 802 drives the magnet block 803 and the movable pressure seat 804 to move downward, so that the movable pressure seat 804 and the fixed pressure seat 805 are in close contact, limiting and fixing the climbing crossbar, so that the climbing crossbar remains stable during the extrusion process and is not prone to displacement, which facilitates subsequent extrusion molding.

[0041] like Figure 1 and Figures 6-8As shown, the extrusion mechanism 9 includes a pair of side plates 901 that are fixedly connected to the outer wall of the fixed frame plate 1. An electric telescopic rod 902 is embedded and connected to the far end of the pair of side plates 901, and an extrusion seat 903 is fixedly connected to the near end of the pair of electric telescopic rods 902. A cleaning and detection mechanism 10 is provided between the extrusion seat 903 and the pulley 702 located on the other side.

[0042] During use, a pair of electric telescopic rods 902 drive a pair of compression seats 903 to move towards each other, contacting the two ends of the climbing crossbar on the ladder blank 13 and compressing them, so that the two ends of the climbing crossbar are tightly fitted and connected to the outer wall of a pair of long and thick rods.

[0043] like Figure 1 and Figures 7-9 As shown, each of the pair of cleaning and detection mechanisms 10 includes a cam 1001. One end of the cam 1001 is fixedly connected to the shaft on the pulley 702 on the other side. The top of the cam 1001 is provided with a pressing plate 1002 in contact with it, and the top of the pressing plate 1002 is fixedly connected with an L-shaped connecting plate 1003. The bottom end of the L-shaped connecting plate 1003 is fixedly connected with a connecting frame 1007, and one end of the connecting frame 1007 is fixedly connected with a lifting sleeve plate 1005. The outer wall of the fixed frame plate 1 is fixedly connected with an I-shaped rod 1004, and the lifting sleeve plate 1005 is sleeved on the outer wall of the I-shaped rod 1004. The outer wall of the I-shaped rod 1004 is sleeved with a second spring 1006, and the top and bottom ends of the second spring 1006 are fixedly connected to the bottom end of the lifting sleeve plate 1005 and the inner bottom end of the I-shaped rod 1004, respectively. One side of the pressing seat 903 is provided with a cleaning brush body 1009 and a sight glass. A visual inspection camera 10010 is provided, and the bottom end of the cleaning brush body 1009 is connected to the top end of the visual inspection camera 10010. A pair of round rods 1008 are fixedly connected to the top end of the connecting frame 1007, and a pair of through holes are drilled at the bottom end of the side plate 901. The top ends of the pair of round rods 1008 pass through the through holes and are fixedly connected to the bottom end of the cleaning brush body 1009. A vibration mechanism 11 is provided between the end of the connecting frame 1007 away from the lifting sleeve plate 1005 and the outer wall of the fixed frame plate 1. Each pair of vibration mechanisms 11 includes an L-shaped ball rod 1101. One end of the L-shaped ball rod 1101 is fixedly connected to the end of the connecting frame 1007 away from the lifting sleeve plate 1005. The outer wall of the L-shaped ball rod 1101 is in contact with the outer wall of the fixed frame plate 1. A plurality of arc-shaped barrier strips 1102 are fixedly connected to the outer wall of the fixed frame plate 1, and the plurality of arc-shaped barrier strips 1102 are all located at the bottom of the L-shaped ball rod 1101.

[0044] During operation, the pair of pulleys 702 and the drive belt 703 rotate and transport, driving the cam 1001 to rotate in one cycle. During this rotation, the cam 1001's protruding end first presses the extrusion plate 1002 and the L-shaped connecting plate 1003 upwards, causing the connecting frame 1007 to move upwards along the I-shaped rod 1004 with the assistance of the lifting sleeve 1005. This stretches the second spring 1006, and through the drive of the round rod 1008, the cleaning brush 1009 and the vision inspection camera 10010 move upwards along the surface of the extrusion seat 903, cleaning debris from the surface of the extrusion seat 903 while simultaneously... The surface integrity of the extrusion seat 903 is inspected to prevent defective extrusion seats 903 from causing poor extrusion quality of the ladder blank 13. At the same time, the presence of debris is prevented from causing wear on the surface of the extrusion seat 903 during the extrusion friction process, reducing the wear and replacement cost of the extrusion seat 903. When the protruding end of the cam 1001 is facing down, the elastic action of the second spring 1006 drives the extrusion plate 1002, the L-shaped connecting plate 1003 and the connecting frame 1007 to return to their downward position, so that the cleaning brush body 1009 and the vision inspection camera 10010 return to their downward position, avoiding obstruction and interference to the subsequent extrusion work of the extrusion seat 903.

[0045] like Figure 1 and Figures 4-5 As shown, the lifting suction mechanism 12 includes a magnetic plate 1201 slidably connected to the inner wall of the rectangular frame 806. Multiple elastic ropes 1202 are fixedly connected between the top of the magnetic plate 1201 and the inner bottom of the rectangular frame 806. A pair of suction frames 1203 are fixedly connected to the end of the rectangular frame 806 away from the support frame 6, and a first air guide pipe 1204 is fixedly connected between the suction frame 1203 and the rectangular frame 806. A first one-way valve 1205 is sleeved on the outer wall of each pair of first air guide pipes 1204. Multiple second air guide pipes 1206 are embedded and connected to the end of the rectangular frame 806 near the support frame 6, and a second one-way valve 1207 is sleeved on the outer wall of each of the multiple second air guide pipes 1206. The gas flow directions of the first air guide pipe 1204 and the second air guide pipe 1206 are opposite.

[0046] During operation, the magnet 803 moves downward, causing the magnetic plate 1201 with a magnetic layer on its surface to move upward under magnetic attraction. This compresses the elastic rope 1202 and draws in outside air through the suction frame 1203. With the assistance of the first air guide pipe 1204 and the first one-way valve 1205, the air flows into the rectangular frame 806. The airflow helps to absorb debris on the convex plate 707, reducing its residue. This allows the debris to fall through the filter screen 4 and into the collection frame 2 for collection. After the magnet 803 moves upward, the magnetic attraction weakens, and the compressed elastic rope 1202 resets, causing the magnetic plate 1201 to reset downward. This forces the air inside the rectangular frame 806 to be discharged outward through the first air guide pipe 1204 and the first one-way valve 1205, dispersing the debris accumulated on the filter screen 4 and allowing it to fall through the filter screen 4 into the collection frame 2, thus enhancing the debris cleaning and collection effect.

[0047] A processing method for a lightweight, high-strength aluminum alloy ladder extrusion forming device includes the following steps:

[0048] S1. First, place the ladder blank 13 on the top of the fixed frame plate 1, and operate the telescopic support mechanism 5 to support and limit the two ends of the ladder blank 13. Then, the moving feeding mechanism 7 drives the climbing crossbar on one side of the ladder blank 13 to the fixed limiting mechanism 8, and shakes off the debris on the surface of the ladder blank 13 during the movement, which is then collected into the collection frame 2 by the filter screen plate 4.

[0049] S2. During the process of moving and conveying the cloud ladder billet 13 driven by the mobile feeding mechanism 7, the cleaning and inspection mechanism 10 and the vibration mechanism 11 are driven to perform lifting and lowering movements. During the lifting and lowering movements, the extrusion seat 903 in the extrusion mechanism 9 is cleaned of debris and defect is detected.

[0050] S3. Next, the fixed limiting mechanism 8 is operated to press down and fix the climbing crossbar on one side of the ladder blank 13, and the lifting suction mechanism 12 is used to extract the falling debris, so that the debris falls into the collection frame 2. Then, the extrusion mechanism 9 is operated to extrude the climbing crossbar on the ladder blank 13 to fit and connect with the ladder blank 13, and extrusion molding is performed.

[0051] This invention provides a lightweight, high-strength aluminum alloy ladder extrusion forming device and its processing method. The working principle is as follows:

[0052] First, a pair of long, thick rods on the ladder blank 13 are placed onto a pair of supporting frames 506 and side frames 508, respectively. On the supporting frames 506, an electric suction cup 507 is driven to adhere and fix the bottom ends of the long, thick rods. Simultaneously, on the side frames 508, a movable bonding plate 5010 and a circular spring 509 are used for limiting and fixing. Next, a motor 705 drives a transmission belt 703 via a pair of pulleys 702, causing the moving sleeve 501 to move horizontally along the auxiliary rod 704. This moves the round-headed convex rod 706 from the top of the filter screen plate 4 onto the convex plate 707. As the convex plate 707 protrudes and presses, the ladder blank 13, the pair of supporting frames 506, and the side frames 508 are positioned on the T-shaped rod 503 and... With the assistance of the first spring 504, the material moves upward. As it continues to move, the round-headed protruding rod 706 moves away from the protruding plate 707 and falls back onto the filter screen plate 4, driving a climbing crossbar on the ladder blank 13 to be conveyed to the fixed pressure seat 805. When the round-headed protruding rod 706 falls downward, it contacts and collides with the top of the filter screen plate 4, generating vibration and shaking off the debris attached to the surface of the ladder blank 13. After being filtered by the filter screen plate 4, the debris falls into the collection frame 2. At the same time, the cam 1001 rotates in one cycle with the rotation of the pulley 702 and the transmission belt 703. During the rotation, the protruding end of the cam 1001 first presses the pressing plate 1002 and the L-shaped connecting plate 1003 upward, causing them to drive the connecting frame upward. With the assistance of the lifting sleeve 1005, 1007 moves upward along the I-shaped rod 1004, stretching the second spring 1006. Driven by the round rod 1008, the cleaning brush 1009 and the visual inspection camera 10010 move upward along the surface of the extrusion seat 903, cleaning debris from the surface of the extrusion seat 903 while simultaneously inspecting its surface integrity. When the protruding end of the cam 1001 faces downward, the elastic action of the second spring 1006 drives the extrusion plate 1002, the L-shaped connecting plate 1003, and the connecting frame 1007 to return to their original positions downward, causing the cleaning brush 1009 and the visual inspection camera 10010 to return to their original positions. Immediately afterwards, the lifting cylinder 802 drives the magnet block 803 and the movable pressure seat 804 to move downward, causing the movable pressure seat 804 to return to its original position. The dynamic pressure seat 804 and the fixed pressure seat 805 are in close contact, limiting and fixing the climbing crossbar. The magnetic block 803 moves downwards, causing the magnetic plate 1201, with its magnetic layer on its surface, to move upwards under magnetic attraction. This compresses the elastic rope 1202, and air is drawn from the outside through the suction frame 1203. With the assistance of the first air guide pipe 1204 and the first one-way valve 1205, the air flows into the rectangular frame 806. This airflow helps to absorb debris from the protruding plate 707, reducing residue on it, so that it can fall through the filter screen 4 into the collection frame 2 for collection. After the magnetic block 803 moves upwards, the magnetic attraction weakens, and the compressed elastic rope 1202 resets, causing the magnetic plate 1201 to reset downwards.Air inside the extruded rectangular frame 806 is discharged outward through the first air guide pipe 1204 and the first one-way valve 1205, blowing away debris accumulated on the filter screen 4 and causing it to fall into the collection frame 2. Then, a pair of electric telescopic rods 902 drive a pair of extrusion seats 903 to move towards each other, contacting and extruding the ends of the climbing crossbars on the ladder blank 13. This causes the ends of the climbing crossbars to fit tightly against and be fixed to the outer walls of the pair of long, thick rods, thus achieving the extrusion molding of the ladder blank 13.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
