Description

Technical Field

[0001] This invention relates to the field of double-head milling technology for aluminum profiles, specifically a method for double-head milling of thermally broken aluminum profiles at a 45° angle. Background Technology

[0002] With the rapid development of the building energy-saving door and window industry, thermally broken aluminum profiles have been widely used in the door and window manufacturing field due to their excellent thermal insulation and sound insulation performance. Thermally broken aluminum door and window frames and sashes mostly adopt the 45° end splicing and corner assembly method of the profile ends. The processing accuracy of the 45° end face of the profile directly affects the splicing effect and is a key process to ensure the sealing and appearance quality of doors and windows. In the mass production of thermally broken aluminum profiles, double-head milling uses cutting tools to process the profiles. Relying on CNC positioning control, the 45° milling and fixed length processing of both ends of the profile are completed simultaneously, which can be adapted to thermally broken aluminum profiles of various cross-sectional specifications. In the existing technology, the 45° angle double-head milling of thermally broken aluminum profiles has certain drawbacks. When the double-head milling cuts the two ends of the profile into a 45° angle, the angle of the profile is usually adjusted or the tool is rotated around the rotating shaft. During the frequent angle reversal adjustment of the tool shaft, gaps are prone to accumulate, causing tool wobbling. This reduces the positional accuracy of the 45° end face after milling. At the same time, the rotating shaft component rotates back and forth for a long time, and the mating pair wears down, resulting in deviations in the milling angle at both ends of the profile and poor consistency of the end face processing. Summary of the Invention

[0003] The purpose of this invention is to provide a method for double-head milling of thermally broken aluminum profiles at a 45° angle, in order to solve the problems mentioned in the background art: during the frequent angle reversal adjustment of the tool shaft, gap accumulation is likely to occur, causing tool wobbling, which reduces the positional accuracy of the 45° end face of the milling. At the same time, the long-term reciprocating rotation of the shaft component causes wear of the mating pair, resulting in deviation of the milling angle at both ends of the profile and poor consistency of end face processing.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example

[0020] Please see Figure 1 As shown, a method for double-head milling of thermally broken aluminum profiles at a 45° angle includes the following steps: S1. Equipment debugging and calibration: After powering on, check the two sets of cutting tools, air pressure and lubrication system above the machine tool base 1. Adjust the angle between the two sets of milling cutters 4 and the profile to 45° or 90° using the angle adjustment component 5. Move the two sets of moving seats 2 to determine the distance between the two sets of milling cutters 4. Perform equipment parameter debugging and self-check to lay the foundation for precise machining. S2. Profile positioning and clamping: The profile placed between the two adjusting seats 3 is clamped and fixed. The clamping device is activated to firmly clamp both ends of the profile. The thermally broken aluminum profile is placed stably on the equipment bracket. The positioning ruler is aligned to ensure that the profile is straight and does not deform. The profile is placed and clamped in a standardized manner to prevent displacement deviation during the processing. S3. Synchronous milling: After the equipment is turned on, the two sets of milling cutters 4 feed at a uniform speed and simultaneously mill the two ends of the profile at 45° or 90°, completing the milling at a uniform speed and smoothly to ensure a flat and clean cut surface. S4. Finished Product Inspection and Finishing Operations: Inspect the angles and dimensional accuracy of the two ends of the processed workpiece, check for burrs and chipped corners on the cut surface, neatly stack the qualified profiles, clean up aluminum chips and debris on the workbench, strictly inspect and repair, control the quality of the processed finished products, standardize the finishing cleaning, and ensure the stability of batch processing accuracy. Please see Figure 2 - Figure 7As shown, two sets of movable seats 2 are arranged on both sides above the machine tool base 1. The two sets of movable seats 2 move closer or further apart to adjust the spacing of the milling cutters 4 above the movable seats 2. The milling cutters 4 are installed above the end face of the adjusting seat 3. The milling cutters 4 are used to cut the profile, thereby cutting both ends of the profile at a specific angle. The angle adjustment component 5 includes a first guide groove 51 and a second guide groove 52 arranged vertically. The first guide groove 51 and the second guide groove 52 are respectively opened on the top surface of the movable seat 2 and the bottom surface of the adjusting seat 3. The first guide groove 51 is opened on the top surface of the movable seat 2, and the second guide groove 52 is opened on the bottom surface of the adjusting seat 3, thereby adjusting the position of the first guide groove 51 and the position of the second guide groove 52. In conjunction with each other, the first guide groove 51 and the second guide groove 52 are provided with a first guide block 53 and a second guide block 54. The first guide block 53 and the second guide block 54 are fixed to the bottom end of the adjusting seat 3. The first guide block 53 and the second guide block 54 are used together to adjust the state of the two sets of milling cutters 4 to 45° or 90°. The first guide block 53 and the second guide block 54 are fixed to the bottom end of the adjusting seat 3, so that the first guide block 53 and the second guide block 54 move along the inside of the first guide groove 51 and the second guide groove 52, so that the adjusting seat 3 moves relative to the moving seat 2, thereby adjusting the state of the two sets of milling cutters 4 to 45° or 90°, thereby cutting the profile into a 45° bevel or a 90° right angle.

[0021] Please see Figure 4 - Figure 7 As shown, the first guide groove 51 and its orientation are adapted to the orientation of the second guide groove 52, so that the tops of the first guide block 53 and the second guide block 54 slide along the interior of the second guide groove 52. The first guide groove 51 consists of a first straight segment 511, an arc segment 512, and a second straight segment 513 connected in sequence. The two ends of the arc segment 512 are tangent to the first straight segment 511 and the second straight segment 513, respectively, so that the first guide block 53 and the second guide block 54 slide smoothly along the interior of the first straight segment 511, the arc segment 512, and the second straight segment 513. The included angle between the first straight segment 511 and the second straight segment 513 is 45°. The first guide block 53 and the first straight segment 54 slide along the interior of the arc segment 511, the arc segment 512, and the second straight segment 513. When both guide blocks 54 are located inside the first straight segment 511, the profile and the adjusting seat 3 are arranged at a 45° angle. When both the first guide block 53 and the second guide block 54 are located inside the first straight segment 511, the adjusting seat 3 and the profile are arranged at a 45° angle, so that the two milling cutters 4 can cut the end of the profile at a right angle. Alternatively, when both the first guide block 53 and the second guide block 54 are located inside the second straight segment 513, the profile and the adjusting seat 3 are arranged at a 90° angle. When both the first guide block 53 and the second guide block 54 are located inside the second straight segment 513, the adjusting seat 3 and the profile are arranged at a 90° angle, so that the two milling cutters 4 can cut the end of the profile at a 45° angle.

[0022] Please see Figure 4 - Figure 7 As shown, fastening bolts 59 are provided in the middle interior of the first guide block 53 and the middle interior of the second guide block 54. The bottom end of the adjusting seat 3 has two first threaded holes 58. The upper ends of the two sets of fastening bolts 59 are threadedly connected to the two first threaded holes 58 respectively. The fastening bolts 59 of the second guide block 54 are screwed into one of the first threaded holes 58, and the fastening bolts 59 of the first guide block 53 are screwed into the first threaded holes 58. Thus, the first guide block 53 and the second guide block 54 below the adjusting seat 3 can be inserted into the interior of the first guide groove 51. The two sets of fastening bolts 59 are used to position the adjusting seat 3 at two points. The lower ends of the two sets of fastening bolts 59 are rotatably connected to the interior of the first guide block 53 and the interior of the second guide block 54 respectively. The movement of the first guide block 53 and the second guide block 54 can drive the adjusting seat 3 to move, thereby adjusting the relative position of the adjusting seat 2 and the adjusting seat 3.

[0023] Please see Figure 5 - Figure 7 As shown, a drive slider 55 is provided inside the first straight segment 511. The drive slider 55 is slidably connected to the inside of the first straight segment 511. The drive slider 55 slides along the inside of the first straight segment 511. A connecting strip 56 is provided between the drive slider 55 and the second guide block 54. The two ends of the connecting strip 56 are rotatably connected to the second guide block 54 and the drive slider 55 respectively through connecting pins 510. The drive slider 55 is used to pull the adjustment seat 3 above the first guide block 53 and the second guide block 54 to the relative position of the profile. The connecting strip 56 is used to rigidly connect the drive slider 55 and the second guide block 54. The drive slider 55 slides along the inside of the first straight segment 511, thereby causing the drive slider 55 to drive the second guide block 54 and the first guide block 53 to move through the connecting strip 56. The second guide block 54 and the first guide block 53 slide back and forth along the inside of the second straight segment 513, the arc segment 512 and the first straight segment 511, thereby changing the position of the adjustment seat 3 back and forth, so that the milling cutter 4 can cut the profile as required.

[0024] Please see Figure 5 - Figure 7As shown, a transversely arranged threaded post 57 is provided inside the movable seat 2 and between the drive slider 55. A transversely arranged second threaded hole 514 is provided inside the drive slider 55. One end of the threaded post 57 is connected to the second threaded hole 514 of the drive slider 55 by a thread. The direction of the threaded post 57 is adapted to the direction of the first straight segment 511. The threaded post 57 can be driven by a motor or rotated manually. The rotation of the threaded post 57 drives the drive slider 55 to move along the inside of the first straight segment 511. Thus, the drive slider 55 can drive the second guide block 54 and the first guide block 53 to move. The threaded post 57 is rigidly connected to the drive slider 55, thereby determining the position of the first guide block 53 and the second guide block 54, and the relative position of the movable seat 2 and the adjusting seat 3.

[0025] Please see Figure 6 and Figure 7 As shown, the cross-sectional shape of the first guide groove 51 is T-shaped, the cross-sectional shape of the first guide block 53 and the cross-sectional shape of the second guide block 54 are both T-shaped, the first guide block 53 and the second guide block 54 slide along the inside of the first guide groove 51, and the upper ends of the first guide block 53 and the second guide block 54 slide along the inside of the second guide groove 52. The cross-sectional shape of the driving slider 55 is cross-shaped, the first guide block 53 and the second guide block 54 slide along the inside of the first guide groove 51, and the driving slider 55 slides along the inside of the first straight line segment 511.

[0026] It should be noted that when the two ends of the profile need to be cut at right angles, the two sets of moving seats 2 above the machine tool base 1 are moved closer or further apart to determine the spacing between the two sets of milling cutters 4. The distance between the milling cutters 4 is the cutting length of the profile. When the two ends of the profile need to be cut at a 45° angle, the spacing between the milling cutters 4 is adjusted to adjust the effective length of the profile. Specifically, the threaded column 57 is rotated so that the threaded column 57 is threadedly connected to the drive slider 55. The drive slider 55 moves along the inside of the first straight segment 511. The first guide block 53 and the second guide block 54 move along the second straight segment 513, the arc segment 512 and the first straight segment 511, thereby changing the first guide block 53 and the second guide block 54 from 90° to 45°. Thus, the position of the adjusting seat 3 relative to the moving seat 2 changes, and the two ends of the profile can be cut at 45°.

[0027] Please see Figure 3 , Figure 8 and Figure 9As shown, a locking assembly 6 is provided inside the first straight segment 511 of the first guide groove 51. The locking assembly 6 includes a third guide groove 61, which is located at the bottom end of the first straight segment 511. A clamping block 62 is provided inside the third guide groove 61. The clamping block 62 slides up and down along the inside of the third guide groove 61. A rotating column 63 is provided inside the movable seat 2. A cam 66 is provided at the end of the rotating column 63. Rotation of the rotating column 63 can drive the cam 66 to rotate. The cam 66 contacts the bottom end of the clamping block 62. The cam 66 is used to abut against the clamping block 62 and clamp it against the bottom end of the second guide block 54 at a 45° angle. Rotating the cam 66 can push the clamping block 62 upward, or the cam 66 can separate from the bottom end of the clamping block 62, so that the clamping block 62 can move up and down in the vertical direction.

[0028] Please see Figure 8 and Figure 9 As shown, each of the bottom corners of the clamping block 62 is provided with a telescopic spring 67. The two ends of the telescopic spring 67 are respectively connected to the clamping block 62 and the third guide groove 61. The telescopic spring 67 is used to push the second guide block 54 up after pressing the clamping block 62 down. The cam 66 separates from the bottom of the clamping block 62. When the second guide block 54 and the drive slider 55 are misaligned with the threaded post 57, the clamping block 62 moves upward under the action of the telescopic spring 67.

[0029] Please see Figure 8 and Figure 9 As shown, the bottom end of the clamping block 62 is provided with a first reserved groove 64 and a second reserved groove 65. The first reserved groove 64 and the second reserved groove 65 are in a cross shape. The threaded post 57 and the rotating post 63 are arranged at 90°. The threaded post 57 is located inside the first reserved groove 64, and the rotating post 63 is located inside the second reserved groove 65. The first reserved groove 64 and the second reserved groove 65 are used to ensure that the rotation of the rotating post 63 and the threaded post 57 will not interfere with the clamping block 62.

[0030] Please see Figure 8 and Figure 9As shown, both sides of the clamping block 62 are chamfered. The side walls of the clamping block 62 are slidably connected to the second guide block 54. When the second guide block 54 slides with the clamping block 62, the clamping block 62 rises and falls in the vertical direction. The chamfered sides of the clamping block 62 drive the slider 55 and the second guide block 54 to move along the direction of the threaded column 57. When the clamping block 62 is pressed down by the second guide block 54 and the driving slider 55, the telescopic spring 67 is compressed. When the second guide block 54 and the driving slider 55 pass the top of the clamping block 62, the telescopic spring 67 can lift the clamping block 62. Then, by rotating the rotating column 63 and the cam 66, the cam 66 is pressed against the clamping block 62 and will not fall down. The top of the clamping block 62 is fixed to the second guide block 54, ensuring that the position of the second guide block 54 and the position of the first guide block 53 will not change. The position of the adjusting seat 3 will not change after it is adjusted to 45°.

[0031] It should be noted that rotating the threaded column 57 causes the drive slider 55 to move along the direction of the threaded column 57, thereby causing the second guide block 54 and the drive slider 55 to slide along the inside of the third guide groove 61. The bottom ends of the second guide block 54 and the drive slider 55 slide against the side wall of the clamping block 62, thereby raising and lowering the clamping block 62 in the vertical direction. By rotating the rotating column 63 and the cam 66, the cam 66 clamps the bottom end of the clamping block 62, so that the clamping block 62 fixes the position of the second guide block 54. When the clamping block 62 and the second guide block 54 are engaged, the top end of the clamping block 62 engages with the bottom end of the first reserved groove 64, thereby determining the position of the first guide block 53 and the second guide block 54, thereby determining the relative position of the adjusting seat 3 and the moving seat 2. The two sets of milling cutters 4 can cut the two ends of the profile at 45°.

[0032] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
