The components perfectly achieve the bending operation and make the force on the workpiece more uniform, effectively avoiding edge stretching.

Description

Technical Field

[0001] This invention belongs to the field of aluminum profile bending technology, specifically a bending device for multi-track aluminum profiles. Background Technology

[0002] Multi-track aluminum profiles are made of aluminum alloy and are mostly used in the production of slide rails. They have varied cross-sectional shapes and can realize the translation and sliding of mechanisms such as sliders. Some multi-track aluminum profiles need to be bent and have a certain curvature before they can be put into use. In the existing technology, the bending machine is driven by a power mechanism to press the aluminum profile. However, the parts that come into contact with the aluminum profile are mostly arc or cylindrical structures. The contact area between the two is very small, which can easily cause the overall stress on the aluminum profile to be uneven. The result is the edge protrusion phenomenon along the front and back of the aluminum profile (the edge protrusion phenomenon refers to the phenomenon that when a metal part is pressed and bent, due to the uneven overall stress, the deformed part will bulge forward and backward perpendicular to the direction of the workpiece). Therefore, increasing the contact area between the bending device and the pressing of the aluminum profile is the direction that this invention is committed to. Summary of the Invention

[0003] The purpose of this invention is to provide a bending device for multi-track aluminum profiles to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a bending device for multi-track aluminum profiles, comprising a worktable and a top seat, and further comprising...

[0005] The mounting base is configured as two sets, left and right, and symmetrically installed on the top of the workbench. It includes an integrally welded welding fixture and a support frame. A placement box is rotatably installed inside the support frame, and the workpiece is placed inside the placement box.

[0006] Hydraulic rod one is installed on the top of the top seat. A primary pressing component is fixedly installed at the telescopic end of the hydraulic rod one. The primary pressing component consists of a connecting plate, hydraulic rod two and a guide column. Hydraulic rod two is installed at the bottom of the connecting plate.

[0007] The secondary pressing component is configured in two sets and installed on the left and right sides of the top of the connecting plate respectively. It includes a receiving column, in which a telescopic column and a spring are movably sleeved. A screw is threaded on the top of the receiving column, and a limit block is fixedly installed on the bottom of the screw.

[0008] The third-level pressing component is installed at the bottom of the first-level pressing component and the second-level pressing component. It includes a contact plate and buffer pads two and three located on top of the contact plate. The telescopic end of the hydraulic rod two is hinged to buffer pad two, and the bottom end of the telescopic column is hinged to buffer pad three.

[0009] Preferably, the guide posts are configured as two sets and are respectively inserted and adapted to the left and right sides of the top of the connecting plate. The top of the guide post is fixedly installed on the bottom of the top seat, and the guide post slides along the axis of the guide post.

[0010] Preferably, the contact plate is made of aluminum alloy, and the buffer pads two and three installed on its top are both made of rubber blocks, and the buffer pads two and three are fixedly installed on the top of the contact plate by adhesive.

[0011] Preferably, a buffer pad is glued to the inner wall of the placement box on the side facing the end of the workpiece, and the buffer pad is made of rubber block. The buffer pad is compressed and placed inside the placement box, and the fixing frame is welded to the top of the workbench.

[0012] Preferably, the spring is compressed and disposed at the top of the cavity of the receiving column, and the telescopic column is elastically supported inside the receiving column by the spring.

[0013] Preferably, a turntable is engaged at the top of the screw, the surface of the turntable is designed with a rounded transition, and a fixing sleeve is fitted on the outer surface of the receiving column, the top of the fixing sleeve being fixedly connected to the top of the connecting plate.

[0014] Preferably, the top seat is fixedly installed on the rear side of the top of the workbench by welding, and multiple sets of reinforcing ribs are installed at the corner of the top of its inner wall.

[0015] Preferably, the fixing frame is in the shape of a gantry frame, and its height is greater than the longitudinal deformation displacement of the workpiece after it is bent.

[0016] Preferably, the top of the inner wall of the placement box has an outward arc transition angle, and the workpiece is interference-fitted to the inner wall of the placement box.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This device has been optimized and upgraded, featuring a newly designed deformable pressing contact plate that maintains full-area compression contact with the workpiece. It utilizes two-stage downward displacement and pressing via hydraulic rods one and two. Hydraulic rod one drives the contact plate to contact the workpiece and continues to apply pressure, while hydraulic rod two drives a buffer pad two to press the contact plate downwards, causing it to bend from the middle. At this time, the receiving column moves downwards relative to the telescopic column and gradually compresses the spring, applying pressure to the buffer pad three. This ensures that all three points of the contact plate are under force, thus pressing the workpiece into a gradually curved shape. During this process, the contact plate, in conjunction with the pressure from hydraulic rods two and one and the spring, applies pressure to the workpiece. The components perfectly achieve the bending operation and ensure more uniform force distribution on the workpiece, effectively preventing edge stretching.

[0019] 2. Then, by threading a screw on the top of the receiving column, the distance between the limiting block and the telescopic column can be changed by rotation. When the contact plate contacts the workpiece, the middle of the contact plate bends first. Driven by the hydraulic rod one, the receiving column continues to move downward and continuously compresses the spring, transmitting pressure to the workpiece through the telescopic column. By changing the distance between the limiting block and the telescopic column, while keeping the distance at which the hydraulic rod two drives the contact plate to apply pressure to the middle of the workpiece unchanged, the pressure distance applied by the telescopic column to the top two sides of the workpiece through the buffer pad three and the contact plate changes. This causes the height values ​​of the parts connected by the buffer pad two and the parts connected by the buffer pad three on the surface of the contact plate to change. Combined with the overall bending of the contact plate, this achieves the function of adjusting different bending arc dimensions of the workpiece.

[0020] 3. Finally, by setting two sets of symmetrically distributed mounting seats, the workpiece can be flexibly adapted and supported. When the workpiece is pressed downward and deformed into a downward depression in the middle, its two ends will drive the placement box to rotate in adaptation. The buffer pads limit and seal the two ends of the workpiece, so that the relative position of the workpiece and the placement box does not change when the workpiece drives the placement box to rotate, thus ensuring that the bending operation of the workpiece is carried out smoothly.

[0030] 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.

[0031] like Figures 1 to 8 As shown, this embodiment of the invention provides a bending device for multi-track aluminum profiles, including a worktable 1 and a top seat 2, and also includes...

[0032] Mounting base 3 is configured as two sets on the left and right and symmetrically installed on the top of the workbench 1. It includes an integrally welded welding fixture 31 and a support frame 32. A placement box 33 is rotatably installed inside the support frame 32, and the workpiece 4 is placed inside the placement box 33.

[0033] Hydraulic rod 5 is installed on the top of the top seat 2. The telescopic end of hydraulic rod 5 is fixedly installed with a primary pressing component 6. The primary pressing component 6 consists of a connecting plate 61, hydraulic rod 62, and guide column 63. Hydraulic rod 62 is installed at the bottom of the connecting plate 61.

[0034] The secondary pressing component 7 is configured in two sets and installed on the left and right sides of the top of the connecting plate 61 respectively. It includes a receiving column 71, a telescopic column 75 and a spring 76 are movably sleeved inside the receiving column 71, a screw 72 is threaded on the top of the receiving column 71, and a limit block 74 is fixedly installed on the bottom of the screw 72.

[0035] The third-level pressing component 8 is installed at the bottom of the first-level pressing component 6 and the second-level pressing component 7. It includes a contact plate 83 and buffer pads 81 and 82 located on top of the contact plate 83. The telescopic end of the hydraulic rod 62 is hinged to the buffer pad 81, and the bottom end of the telescopic column 75 is hinged to the buffer pad 82.

[0036] This device has been optimized and upgraded, featuring a newly designed deformable and pressing contact plate 83 that maintains full-area compression contact with the workpiece 4. It utilizes two-stage downward displacement and pressing via hydraulic rods 5 and 62. Hydraulic rod 5 drives the contact plate 83 to contact the workpiece 4 and continues to apply pressure, while hydraulic rod 62 drives the buffer pad 81 to press the contact plate 83 downwards, causing it to bend from the middle. At this time, the receiving column 71 moves downwards relative to the telescopic column 75 and gradually compresses the spring 76, applying pressure to the buffer pad 82. This ensures that all three points of the contact plate 83 are under force, thus pressing the workpiece 4 into a gradually curved shape. During this process, the contact plate 83, in conjunction with the pressure from hydraulic rod 62, hydraulic rod 5, and spring 76, applies pressure to the workpiece 4. The components perfectly achieve the bending operation and ensure more uniform force distribution on the workpiece 4, effectively preventing edge stretching.

[0037] Then, by threading a screw 72 onto the top of the receiving column 71, the distance between the limiting block 74 and the telescopic column 75 can be changed by rotation. When the contact plate 83 contacts the workpiece 4, the middle part of the contact plate 83 bends first. Driven by the hydraulic rod 5, the receiving column 71 continues to move downward and continuously compresses the spring 76, transmitting pressure to the workpiece 4 through the telescopic column 75. By changing the distance between the limiting block 74 and the telescopic column 75, while keeping the distance at which the hydraulic rod 62 drives the contact plate 83 to apply pressure to the middle part of the workpiece 4 unchanged, the distance at which the telescopic column 75 applies pressure to the top two sides of the workpiece 4 through the buffer pad 3 82 and the contact plate 83 is changed. This causes the height of the part connected to the buffer pad 2 81 and the part connected to the buffer pad 3 82 on the surface of the contact plate 83 to change. Combined with the overall bending of the contact plate 83, this achieves the function of adjusting different bending arc dimensions of the workpiece 4.

[0038] Finally, by setting two sets of mounting seats 3 symmetrically distributed on the left and right, the workpiece 4 is flexibly adapted and supported. When the workpiece 4 is pressed downward and deformed into a downward depression in the middle, its two ends will drive the placement box 33 to rotate in adaptation. The buffer pad 34 limits and seals the two ends of the workpiece 4, so that when the workpiece 4 drives the placement box 33 to rotate, the relative position of the workpiece 4 and the placement box 33 does not change, thereby ensuring that the bending operation of the workpiece 4 is carried out smoothly.

[0039] Among them, the guide posts 63 are configured in two sets and are respectively inserted and adapted to the left and right sides of the top of the connecting plate 61. The top of the guide post 63 is fixedly installed on the bottom of the top seat 2, and the guide post 63 slides along the axis of the guide post 63.

[0040] The guide column 63 is used to guide the connecting plate 61 when it moves up and down, so that the secondary pressing component 7 and the tertiary pressing component 8, which can be installed on the primary pressing component 6, are more stable during operation, thus improving the stability of the device.

[0041] The contact plate 83 is made of aluminum alloy, and the buffer pads 81 and 82 installed on its top are both made of rubber blocks. The buffer pads 81 and 82 are both fixedly installed on the top of the contact plate 83 by adhesive.

[0042] The contact plate 83 is made of aluminum alloy and is responsible for contacting the upper surface of the workpiece 4. It works with the hydraulic rod 62 to apply pressure and deform itself, thereby pressing the workpiece 4 to deform and bend. The bent contact plate 83 can always stick to the workpiece 4, thereby evenly distributing the pressure from the first pressing component 6 and the second pressing component 7 to the surface of the workpiece 4, making the force on the workpiece 4 more balanced.

[0043] Among them, a buffer pad 34 is glued to the inner wall of the placement box 33 on the side facing the end of the workpiece 4, and the buffer pad 34 is made of rubber block. The buffer pad 34 is squeezed and set inside the placement box 33, and the fixing frame 31 is welded to the top of the workbench 1.

[0044] The workpiece 4 is placed in the placement box 33, and its two ends are deformed by being squeezed with the buffer pad 34, so that the workpiece 4 can be more tightly connected with the placement box 33. The workpiece 4 is limited and supported by the placement box 33.

[0045] The spring 76 is compressed and installed at the top of the inner cavity of the receiving column 71, and the telescopic column 75 is elastically supported inside the receiving column 71 by the spring 76.

[0046] like Figure 2 and Figure 3 As shown, the spring 76 is used to maintain an elastic and buffered pressure space between the receiving column 71 and the telescopic column 75. When the contact plate 83 contacts the upper surface of the workpiece 4, the receiving column 71 continues to move downward under the drive of the hydraulic rod 5. At this time, the moving speed of the telescopic column 75 decreases. At this time, the spring 76 is compressed and generates elastic force, which finally acts on the workpiece 4.

[0047] Among them, the top of the screw 72 is fitted with a turntable 73, the surface of the turntable 73 is designed with a rounded transition, and the outer surface of the receiving column 71 is also fitted with a fixing sleeve 77, the top of the fixing sleeve 77 is fixedly connected to the top of the connecting plate 61.

[0048] When the telescopic column 75 continuously applies pressure to the workpiece 4, the workpiece 4 as a whole will generate an upward reaction force. By setting the screw 72, the distance between the limiting block 74 and the telescopic column 75 is changed, and the height of the limiting contact between the telescopic column 75 and the limiting block 74 is changed. This causes the height value of the part connected to the buffer pad 2 81 and the part connected to the buffer pad 3 82 on the surface of the contact plate 83 to change. In conjunction with the overall bending of the contact plate 83, the function of adjusting the different bending arc size of the workpiece 4 is realized.

[0049] Among them, the top seat 2 is fixedly installed on the rear side of the top of the workbench 1 by welding, and multiple sets of reinforcing ribs are installed at the corner of the top of its inner wall;

[0050] The workbench 1 provides overall support for the top seat 2, mounting seat 3 and workpiece 4, and provides a fixing function for the hydraulic rod 5. The reinforcing rib can improve the connection structure strength of the vertical part of the top seat 2.

[0051] Among them, the fixed frame 31 is in the shape of a gantry frame, and its height value is greater than the longitudinal deformation displacement of the workpiece 4 after it is bent.

[0052] The gantry-shaped structure of the fixed frame 31 can evenly absorb and distribute the pressure on the workpiece 4, and its height can prevent the bottom of the workpiece 4 from contacting the surface of the worktable 1 after it is bent.

[0053] The top of the inner wall of the placement box 33 is provided with an outward arc transition angle, and the workpiece 4 is interference-fitted to the inner wall of the placement box 33.

[0054] The rounded transition angle at the top of the inner wall of the placement box 33 helps the workpiece 4 to be locked and placed inside the placement box 33, preventing the workpiece 4 from being scratched by the sharp part at the top of the placement box 33.

[0055] Working principle and usage process:

[0056] First, place workpiece 4 on mounting base 3, so that both ends of workpiece 4 are locked inside the left and right sets of placement boxes 33, causing the buffer pad 34 to be compressed and deformed, and workpiece 4 is placed horizontally. Then, activate hydraulic rod 5 to drive the first-stage pressing component 6, the second-stage pressing component 7, and the third-stage pressing component 8 to move downward. When the bottom of contact plate 83 makes contact with the top limit of workpiece 4, activate hydraulic rod 62 to continuously press the buffer pad 81 and the middle of contact plate 83 downward. When the bottom of contact plate 83 is in contact with the top of workpiece 4, the middle of contact plate 83 is first subjected to force and presses down on the middle of workpiece 4. At this time, contact plate 83 first bends and deforms, and then applies pressure to workpiece 4. At this time, hydraulic rod 62... 5 continues to push the secondary pressing component 7 downwards. The two sides of the buffer pad 82 contact the workpiece 4. Through the continuous compression from the receiving column 71, spring 76 and telescopic column 75, it gradually deforms. At this time, the telescopic column 75 is driven upwards by the reaction force of the workpiece 4 and compresses the spring 76 until the telescopic column 75 contacts the limit block 74. Then, the hydraulic rod 5 stops. At this time, the entire workpiece 4 is also pressed into the curved state. Then, the hydraulic rod 62 stops. When the entire workpiece 4 is curved, its two ends will drive the two sets of placement boxes 33 to rotate in adaptation. During the entire process of the workpiece 4 being curved, the contact surface between the contact plate 83 and the workpiece 4 remains unchanged, so that the workpiece 4 is subjected to balanced force during the bending process.

[0057] Then, when it is necessary to adjust the workpiece 4 to different bending arc dimensions, simply rotate the turntable 73 and drive the limit block 74 and spring 76 to move along their own axis, changing the distance between the limit block 74 and the telescopic column 75. Thus, during the process of the hydraulic rod 5 driving the first pressing component 6 and the second pressing component 7 to move downward, the height of the limit contact between the telescopic column 75 and the limit block 74 is changed, so that the height value of the part connected to the buffer pad 2 81 and the part connected to the buffer pad 3 82 on the surface of the contact plate 83 changes. With the overall bending of the contact plate 83, the function of adjusting the workpiece 4 to different bending arc dimensions is realized.
