Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy ladder processing, and specifically to a light-weight and high-strength aluminum alloy ladder extrusion molding device and a processing method thereof. Background Art

[0002] ‌Aluminum alloy ladder‌ is a modern climbing tool, mainly used for firefighting and rescue purposes. The design of this ladder combines modern technology and material science. It uses aluminum alloy as the main material and has the advantages of lightness, high strength, and corrosion resistance. Aluminum alloy ladders are widely used, not only for firefighting and rescue, but also for high-altitude operations, equipment installation, gardening operations and other occasions. In the processing of aluminum alloy ladders, the cut equidistant climbing crossbars are often connected with the long thick bars on both sides, and then the climbing crossbars are fixedly connected with the long thick bars on both sides by extrusion to promote the formation of the ladder.

[0003] At present, in the process of extrusion forming of aluminum alloy ladders, the surface of the cut equidistant climbing cross bars is often attached with some cutting debris. If it is not cleaned in time, the extrusion tool may not fit tightly enough with the long thick bars on both sides due to the influence of too much debris, which affects the tightness of the connection and leads to quality deterioration. It is easy to loosen in the subsequent long-term use, affecting the stability of use. In addition, the extrusion friction of the debris will cause wear on the surface of the extrusion tool, increasing the loss and replacement cost of the extrusion tool.

[0038] During use of the present solution, a pair of long and thick rods on the cloud ladder blank 13 are placed on a pair of supporting frames 506 and a side frame 508 respectively, and on the supporting frame 506, the electric suction cup 507 is driven to adsorb and fix the bottom ends of the pair of long and thick rods.

Then, the motor 705 drives the transmission belt 703 through a pair of pulleys 702 to engage and drive, so that it drives the movable sleeve block 501 to move horizontally along the auxiliary rod 704, so that the round-headed protruding rod 706 moves from the top of the filter screen plate 4 to the protruding plate 707, and with the convex squeezing of the convex plate 707, the ladder body 13 and a pair of supporting frames 506 and the side frames 508 move upward with the assistance of the T-bar 503 and the first spring 504, and with the continued movement, the round-headed convex rod 706 moves away from the convex plate 707 and continues to fall back onto the filter screen plate 4, thereby driving the ladder body 13 to perform stable, intermittent and orderly transportation, and the round-headed convex rod 706 falls back and collides with the top of the filter screen plate 4, generating vibrations, shaking off the debris attached to the surface of the ladder body 13, and the debris falls into the collection frame 2 after being filtered by the filter screen plate 4, thereby cleaning and collecting the debris.

[0039] like Figure 1 and Figure 4-Figure 5 As shown, the fixed limiting mechanism 8 includes a top connection platform 801 fixedly connected to the top of the fixed frame plate 1, the top of the top connection platform 801 is embedded with a lifting cylinder 802, and the output end of the lifting cylinder 802 is fixedly connected to a magnet block 803, the bottom end of the magnet block 803 is fixedly connected to a movable pressure seat 804, the top of the filter screen plate 4 is fixedly connected to a rectangular frame 806, and the top of the rectangular frame 806 is fixedly connected to a fixed pressure seat 805, 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, and a lifting and suction mechanism 12 is provided between the inside of the rectangular frame 806 and the magnet block 803.

[0040] During use of this solution, after a climbing cross bar on the ladder blank 13 is transported to the inside of 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, and the climbing cross bar is limited and fixed, so that the climbing cross bar remains stable during the extrusion process and is not easily displaced, so as to facilitate subsequent extrusion molding.

[0041] like Figure 1 and Figure 6-Figure 8As shown, the extrusion mechanism 9 includes a pair of side connecting plates 901 fixedly connected to the outer wall of the fixed frame plate 1, the ends of the pair of side connecting plates 901 away from each other are embedded with electric telescopic rods 902, and the ends of the pair of electric telescopic rods 902 close to each other are fixedly connected with extrusion seats 903, and a cleaning detection mechanism 10 is provided between the extrusion seat 903 and the pulley 702 on the other side.

[0042] During use of this solution, a pair of electric telescopic rods 902 drive a pair of extrusion seats 903 to move toward each other, contact the two ends of the climbing cross bar on the ladder blank 13, and squeeze it, so that the two ends of the climbing cross bar are tightly fitted and connected and fixed to the outer walls of a pair of long and thick rods.

[0043] like Figure 1 and Figure 7-Figure 9 As shown, a pair of cleaning detection mechanisms 10 each include a cam 1001, one end of the cam 1001 is fixedly connected to the rotating shaft on the pulley 702 on the other side, the top of the cam 1001 is provided with an extrusion plate 1002 in contact with it, and the top of the extrusion 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 1005, the outer wall of the fixed frame plate 1 is fixedly connected with an I-shaped rod 1004, and the lifting sleeve 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 respectively fixedly connected to the bottom end of the lifting sleeve 1005 and the inner bottom end of the I-shaped rod 1004, and one side of the extrusion seat 903 is respectively provided with a cleaning brush body 1009 and a visual inspection brush 1007. The visual inspection camera 10010 is connected, and the bottom end of the cleaning brush body 1009 is connected to the top of the visual inspection camera 10010. The top of the connecting frame 1007 is fixedly connected with a pair of round rods 1008, and the bottom end of the side connecting plate 901 is opened with a pair of through holes. 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 1005 and the outer wall of the fixed frame plate 1. The pair of vibration mechanisms 11 both include 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 1005, the outer wall of the L-shaped ball rod 1101 is in contact with the outer wall of the fixed frame plate 1, and the outer wall of the fixed frame plate 1 is fixedly connected with a plurality of arc-shaped obstacle bars 1102, and the plurality of arc-shaped obstacle bars 1102 are all located at the bottom of the L-shaped ball rod 1101.

[0044] During the use of this solution, during the rotation transmission and conveying process of a pair of pulleys 702 and a transmission belt 703, the cam 1001 is driven to perform a cycle of rotational motion, and during the rotation process, the convex end of the cam 1001 first presses the extrusion plate 1002 and the L-shaped connecting plate 1003 upward to move upward, so that the connecting frame 1007 moves upward along the I-shaped rod 1004 with the assistance of the lifting sleeve 1005, stretching the second spring 1006, and driving the cleaning brush body 1009 and the visual inspection camera 10010 along the surface of the extrusion seat 903 upward through the round rod 1008, while cleaning the debris on the surface of the extrusion seat 903. The surface integrity of the extrusion seat 903 is detected to prevent the defective extrusion seat 903 from performing extrusion work and causing the extrusion molding quality of the ladder blank 13 to deteriorate. At the same time, the presence of debris prevents the surface of the extrusion seat 903 from being worn during the extrusion friction process, thereby reducing the loss and replacement cost of the extrusion seat 903. When the raised end of the cam 1001 is facing 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 reset downward, so that the cleaning brush body 1009 and the visual inspection camera 10010 are reset downward, thereby avoiding obstruction and interference to the subsequent extrusion work of the extrusion seat 903.

[0045] like Figure 1 and Figure 4-Figure 5 As shown, the lifting and suction mechanism 12 includes a magnetic plate 1201 which is slidably connected to the inner wall of the rectangular frame 806, and a plurality of elastic ropes 1202 are fixedly connected between the top of the magnetic plate 1201 and the inner bottom end of the rectangular frame 806. A pair of air suction frames 1203 are fixedly connected to the end of the rectangular frame 806 away from the support frame 6, and a first air duct 1204 is fixedly connected between the air suction frame 1203 and the rectangular frame 806, and the outer walls of the pair of first air ducts 1204 are both sleeved with a first one-way valve 1205, and a plurality of second air ducts 1206 are embedded and connected to one end of the rectangular frame 806 close to the support frame 6, and the outer walls of the plurality of second air ducts 1206 are both sleeved with a second one-way valve 1207, and the gas flow directions of the first air duct 1204 and the second air duct 1206 are opposite.

[0046] During use of the present solution, the magnet block 803 moves downward, causing the magnetic plate 1201 with a magnetic layer on its surface to move upward under magnetic attraction, compressing the elastic rope 1202, and drawing external air through the air extraction frame 1203, which flows into the rectangular frame 806 with the assistance of the first air duct 1204 and the first one-way valve 1205. With the help of the flow of air, the debris on the convex plate 707 is absorbed, reducing the residue on the convex plate 707, so that it can pass through the filter screen plate 4 and fall into the collection frame 2 for collection. After the magnet block 803 moves upward, the magnetic attraction weakens, and the compressed elastic rope 1202 is reset, driving the magnetic plate 1201 to reset downward, squeezing the air inside the rectangular frame 806 to be discharged outward through the first air duct 1204 and the first one-way valve 1205, blowing away the debris accumulated on the filter screen plate 4, and causing the debris to pass through the filter screen plate 4 and fall into the collection frame 2, thereby enhancing the debris cleaning and collection effect.

[0047] A processing method for a lightweight and high-strength aluminum alloy ladder extrusion molding device comprises 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 mobile feeding mechanism 7 drives the climbing cross bar on one side of the ladder blank 13 to move to the fixed limiting mechanism 8, and shakes off the debris on the surface of the ladder blank 13 during the movement, and collects it into the collection frame 2 with the help of the filter screen plate 4;

[0049] S2, during the process of the moving feeding mechanism 7 driving the ladder blank 13 to move and transport, the cleaning and detection mechanism 10 and the vibration mechanism 11 are driven to perform lifting and lowering movements, and during the lifting and lowering movements, the extrusion seat 903 in the extrusion mechanism 9 is cleaned of debris and inspected for defects;

[0050] S3, then operate the fixed limiting mechanism 8 to press down and fix the climbing cross bar on one side of the ladder blank 13, and cooperate with the lifting and suction mechanism 12 to extract the fallen debris, so that the debris falls into the collection frame 2, and then operate the extrusion mechanism 9 to extrude the climbing cross bar on the ladder blank 13 to fit and connect the ladder blank 13 to perform extrusion molding.

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

[0052] First, place a pair of long and thick rods on the cloud ladder blank 13 on a pair of supporting frames 506 and a side frame 508 respectively, and drive the electric suction cup 507 on the supporting frame 506 to adsorb and fix the bottom ends of the pair of long and thick rods. At the same time, on the side frame 508, the movable fitting plate 5010 and the circular spring 509 are used to limit and fix them. Then, the motor 705 drives the transmission belt 703 through a pair of pulleys 702 to engage and drive, so that it drives the movable sleeve 501 to move horizontally along the auxiliary rod 704, so that the round-headed protruding rod 706 moves from the top of the filter screen plate 4 to the protruding plate 707. As the protrusion of the protruding plate 707 is squeezed, the cloud ladder blank 13 and the pair of supporting frames 506 and the side frame 508 are moved on the T-shaped rod 503 and The first spring 504 assists in the upward movement, and 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, driving a climbing crossbar on the cloud ladder blank 13 to be transported to the fixed pressure seat 805, and when the round-headed protruding rod 706 falls back downward, it contacts and collides with the top of the filter screen plate 4, generating vibrations, shaking off the debris attached to the surface of the cloud ladder blank 13, which falls into the collection frame 2 after being filtered by the filter screen plate 4. At the same time, the cam 1001 performs a cycle of rotational motion with the rotation of the pulley 702 and the transmission of the transmission belt 703, and in the process of rotation, the extrusion plate 1002 and the L-shaped connecting plate 1003 are first squeezed upward by the raised end of the cam 1001 to move upward, so that it drives the connecting frame 1007 moves upward along the I-shaped rod 1004 with the assistance of the lifting sleeve 1005, stretching the second spring 1006, and driving the cleaning brush body 1009 and the visual inspection camera 10010 along the surface of the extrusion seat 903 upward through the round rod 1008, while cleaning the debris on the surface of the extrusion seat 903, the surface integrity of the extrusion seat 903 is inspected, and when the raised end of the cam 1001 is 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 reset downward, so that the cleaning brush body 1009 and the visual inspection camera 10010 are reset downward, and then, the lifting cylinder 802 drives the magnet block 803 and the movable pressure seat 804 to move downward. The dynamic pressure seat 804 and the fixed pressure seat 805 are in close contact to limit and fix the climbing crossbar, and the magnet block 803 moves downward, so that the magnetic plate 1201 with a magnetic layer on the surface moves upward under magnetic attraction, compressing the elastic rope 1202, and drawing the external air through the air extraction frame 1203, and with the assistance of the first air duct 1204 and the first one-way valve 1205, it flows into the rectangular frame 806. With the help of the flow of air, the debris on the convex plate 707 is absorbed, and the residue on the convex plate 707 is reduced, so that it can be dropped into the collection frame 2 for collection through the filter plate 4. After the magnet block 803 moves upward, the magnetic attraction weakens, and the compressed elastic rope 1202 is reset, driving the magnetic plate 1201 to reset downward.The 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 the debris accumulated on the filter screen plate 4, allowing the debris to pass through the filter screen plate 4 and fall into the collection frame 2. Then, a pair of electric telescopic rods 902 drive a pair of extrusion seats 903 to move toward each other, contact the two ends of the climbing crossbar on the ladder blank 13, and squeeze them, so that the two ends of the climbing crossbar are tightly fitted and connected and fixed with the outer walls of the pair of long and thick rods, thereby realizing the extrusion molding of the ladder blank 13.
