Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, and in particular to an aluminum profile end face milling machine. Background Technology

[0002] Aluminum profiles refer to long strip metal products with specific cross-sectional shapes and dimensions, made primarily of aluminum through processes such as hot melting and extrusion. In modern industrial systems, the applications of aluminum profiles are becoming increasingly diverse, ranging from building envelopes to the supporting frameworks of precision automated production lines. As a result, the requirements for their end-face perpendicularity, flatness, and surface quality are becoming increasingly stringent.

[0003] Currently, various specialized milling machines have emerged in the industry for milling the end faces of aluminum profiles. For example, Chinese patent CN105880696B discloses an aluminum profile end face milling machine, which includes a milling machine housing with crossbeams on both the front and rear sides inside the housing. A positioning and clamping device is mounted on the crossbeams, and the cutting tool device moves back and forth through a slider cooperating with the guide rail at the bottom of the positioning and clamping device. The positioning and clamping device has a platform with a reference plate and a fixed clamp, as well as a Z-axis support column, which can perform horizontal and vertical positioning and clamping of the profile. The cutting tool device includes a worktable and a vertical plate, and a milling cutter device consisting of a locking screw, a U-shaped pad, a disc milling cutter sleeve, and a disc milling cutter support pad is set on the worktable, providing stable milling capabilities. Such milling machines can complete the forming of aluminum profile end faces, but objectively speaking, the workpiece loading and unloading process still mainly relies on manual operation. Each time an end milling operation is completed, the operator needs to manually loosen the clamps, remove the processed profile, move the next profile to be processed, and reposition and clamp it. The time spent waiting for manual material changes accounts for a significant portion of the entire processing cycle. This results in long auxiliary times during continuous processing, making it difficult to further improve the cycle time efficiency of mass production. Furthermore, the physical exertion of operators during the repeated handling and clamping of profiles is quite noticeable.

[0048] When this device is needed, first place several aluminum profiles to be processed on the top side of the loading rack 37. The inclined setting of the loading rack 37 causes the aluminum profiles to slide downwards under their own weight until the bottom aluminum profile is stopped by the abutment frame 38. Then, according to the specific length of the aluminum profile to be processed, manually adjust the position of the adjusting push rod 47 at the front end of the slide rod 44, insert the pin 46 into the corresponding adjusting hole 48 on the slide rod 44, so that the initial position of the adjusting push rod 47 matches the length of the aluminum profile, and complete the preparation work before use.

[0049] After the above preparations are completed, the control box 2 starts the motor 22. The output shaft of the motor 22 rotates clockwise, driving the leftmost connecting shaft 25 inside the mounting housing 21 to rotate. The synchronous pulley 23 sleeved on the rear side of the connecting shaft 25 transmits power to the adjacent synchronous pulley 23 through the synchronous belt 24, so that all connecting shafts 25 rotate synchronously.

Each set of two threaded sleeves 30, which are symmetrically distributed from left to right, drives the corresponding moving block 31 to move outward along guide housing 27 to the full stroke position of threaded sleeve 30. Guide rod 32 drives limit frame 34 to move outward accordingly. Spring 33 provides elastic buffer between limit frame 34 and moving block 31. While drive shaft 29 rotates, the spring 33, which is sleeved on drive shaft 2, drives the corresponding moving block 31 to move outward along guide housing 27 to the full stroke position of threaded sleeve 30. The bevel gear 36 at the top of the vertical shaft 35 meshes with the shaft 9, driving the vertical shaft 35 to rotate. The synchronous pulley 41 at the lower end of the vertical shaft 35 drives the synchronous pulley 41 on the screw 40 to rotate through the synchronous belt 42, causing the screw 40 to rotate. The screw 40 drives the pusher 43 to move upward along the abutment frame 38 to the highest point. During the upward movement, the pusher 43 lifts the lowest aluminum profile that is abutted by the abutment frame 38 and moves it upward over the abutment frame 38. The aluminum profile then slides along the inclined plane into a set of support rods that are already in place on the receiving frame 26.

[0051] As the pusher 43 moves upward, the connecting rod 45 drives the slide rod 44 to slide backward along the inside of the feeding channel. The slide rod 44 drives the adjusting push rod 47 to move backward together, making room for the subsequent aluminum profile to enter the feeding channel. Then, the control box 2 controls the motor 22 to reverse, and the output shaft of the motor 22 rotates counterclockwise. Through the transmission of the synchronous pulley 23 and the synchronous belt 24, the connecting shaft 25 reverses, and the receiving frame 26 rotates counterclockwise forty-five degrees to reset, turning a set of support rods carrying the aluminum profile into the inside of the feeding channel. The aluminum profile is now located in the feeding channel and is in a state of waiting to be processed.

[0052] At the same time, the control box 2 controls the motor 3 28 to reverse, the output shaft of the motor 3 28 drives the drive shaft 29 to reverse, the four sets of threaded sleeves 30 drive the corresponding moving blocks 31 to move along the guide housing 27 towards the aluminum profile, the guide rod 32 drives the limiting frame 34 to move towards each other, the two limiting frames 34 abut from the left and right sides and clamp the aluminum profile in the feeding channel, the spring 1 33 is compressed to provide a stable clamping force, at this time the aluminum profile is restricted to only move in the front and back direction.

[0053] The drive shaft 29 reverses, and through the transmission of bevel gear 36, vertical shaft 35, synchronous pulley 41 and synchronous belt 42, the screw 40 reverses. The pusher 43 moves downward along the abutment frame 38 and resets to the bottom. The remaining aluminum profiles on the feeding frame 37 slide downward under the action of gravity until the bottom aluminum profile is abutted again by the abutment frame 38. When the pusher 43 moves downward, it drives the slide rod 44 to slide forward along the inside of the feeding channel through the connecting rod 45. The slide rod 44 drives the adjusting push rod 47 to move forward. The front end of the adjusting push rod 47 pushes the aluminum profile in the feeding channel forward until the front end of the aluminum profile abuts the rear side of the calibration plate 52, completing the automatic feeding and axial positioning of the aluminum profile. At this point, the feeding and positioning process is completed, and the control box 2 shuts down motor 22 and motor 328.

[0054] Next, the control box 2 starts the motor 7 and the electric slide rail 3. The output shaft of the motor 7 rotates upward, driving the rotating shaft 9 to rotate at high speed through the coupling 8. The rotating shaft 9 drives the four milling cutters 10 to rotate at high speed inside the protective shell 11. At the same time, the large gear 17 rotates synchronously. The electric slide rail 3 drives the slider 4 to move to the left. The slider 4 drives the fixed shell 5 and all the components installed on it to move to the left synchronously. During the movement of the fixed shell 5 to the left, the operating port gradually approaches and aligns with the end of the aluminum profile in the feeding channel. The high-speed rotating milling cutter 10 passes through the operating port to perform milling on the end face of the aluminum profile.

[0055] During milling, the large gear 17 drives the small gear 18 to mesh and rotate. The small gear 18 drives the impeller 20 to rotate at high speed inside the air duct 16. The high-speed rotation of the impeller 20 creates a negative pressure inside the dust collection box 14. The chips and dust generated during processing are drawn into the suction pipe 12 through the expansion cylinder 13 under the negative pressure, and then enter the dust collection box 14 through the suction pipe 12. When the airflow carries the debris through the interception filter 19, the debris is intercepted and retained inside the dust collection box 14. The filtered gas is discharged outside the device through the air duct 16. While the impeller 20 rotates and generates negative pressure, the airflow flows through the interior of the fixed housing 5 and is discharged from the exhaust holes 64 opened on the lower left and right sides of the fixed housing 5 to cool the motor 7 inside the fixed housing 5.

[0056] As the fixed housing 5 moves to the left, the abutment wheel 54 moves to the left simultaneously. During the leftward movement, the abutment wheel 54 first contacts the inclined surface of the calibration plate 52 and rolls along the inclined surface. Under the guidance of the inclined surface of the calibration plate 52, the abutment wheel 54 applies downward pressure to the calibration plate 52, forcing the calibration plate 52 to overcome the elastic force of the second spring 51 and slide downward along the column 50 in the reinforcing frame 49. The second spring 51 is compressed. As the calibration plate 52 moves downward, the lower part of the calibration plate 52 is inserted into the square through-hole, leaving space for the milling cutter 10 to make room and avoiding interference between the calibration plate 52 and the fixed housing 5.

[0057] When the calibration plate 52 moves downward, its bottom side abuts against the traction plate 60 and pushes the traction plate 60 downward. The traction plate 60 moves downward under force and pulls the isolation cloth 57. The isolation cloth 57 drives the sliding rod 58 to overcome the elastic force of the elastic rib 59 and slide backward inside the guide hopper 56. The inlet on the top side of the guide hopper 56 is opened. Larger debris generated during the processing falls into the guide hopper 56 under the action of gravity and enters the waste frame 55 through the opening on the bottom side of the guide hopper 56 and the top rear side of the waste frame 55 for temporary collection.

[0058] When the slider 4, carrying the fixed housing 5, moves to the leftmost end of the electric slide rail 3, the milling cutter 10 completes the first milling stroke on the end face of the aluminum profile. The electric slide rail 3 then drives the slider 4 to move to the right to begin the return stroke. The fixed housing 5 and the milling cutter 10 move to the right, and the milling cutter 10 performs a secondary finishing process on the end face of the aluminum profile. During the return stroke, the abutment wheel 54 rolls on the top surface of the calibration plate 52, continuously keeping the calibration plate 52 in a downward-pressed state. When the slider 4 moves to the rightmost end of the electric slide rail 3, the fixed housing 5 and the abutment wheel 54 return to their initial horizontal position, and the abutment wheel 54 disengages from the top surface of the calibration plate 52. Apply downward pressure to calibration plate 52, release the elastic force stored in spring 51, drive calibration plate 52 to move upward along column 50 to reset, calibration plate 52 disengages from square opening, releases downward pressure on traction plate 60 when calibration plate 52 moves upward, elastic rib 59 releases elastic force to drive sliding rod 58 to slide forward to reset, sliding rod 58 drives isolation cloth 57 to move forward to cover the top side entrance of guide hopper 56 again, traction plate 60 resets upward under the drive of isolation cloth 57, waste collection channel is closed, thus completing one milling cycle, control box 2 shuts off motor 7 and electric slide rail 3.

[0059] After one milling operation is completed, control box 2 controls motor 22 to start again. The output shaft of motor 22 continues to rotate according to the program. Through synchronous pulley 23 and synchronous belt 24, it drives the connecting shaft 25 to rotate. The receiving rack 26 rotates 90 degrees counterclockwise. The set of support rods that originally extended into the feeding channel to support the processed aluminum profiles moves away from the feeding channel. After losing the support of the support rods, the aluminum profiles fall into the receiving bin under the action of gravity. At the same time, the adjacent set of support rods that were originally in the vertical position rotates 90 degrees counterclockwise to reach the horizontal position and extends into the feeding channel to provide support for the next feeding.

[0060] While motor 22 is working, motor 3 28 starts synchronously. Drive shaft 29 rotates and drives moving block 31 outward through threaded sleeve 30 to half the length of threaded sleeve 30. Guide rod 32 drives limit frame 34 to move outward a distance, temporarily releasing the clamping of the processed aluminum profile in the feeding channel. Drive shaft 29 is simultaneously driven by bevel gear 36 and vertical shaft 35, and drives screw 40 to rotate through synchronous pulley 41 and synchronous belt 42. Screw 40 drives push frame 43 to move upward halfway. Push frame 43 rises to the bottom surface of the new bottom aluminum profile on the feeding rack 37 and lifts it to contact, preparing for the next feeding. When push frame 43 moves upward, it drives slide rod 44 to move backward again through connecting rod 45, and adjusts push rod 47 to retract and disengage from aluminum profile.

[0061] After the aluminum profile falls into the receiving hopper, the control box 2 starts the motor 62. The output shaft of the motor 62 extends backward to drive the screw 63 to rotate. The screw 63 drives the push plate 61 to slide backward along the bottom side of the receiving hopper. The push plate 61 pushes the processed aluminum profile that has fallen into the receiving hopper backward and pushes it out of the machine housing 1 for collection. After the push is completed, the motor 62 reverses and drives the screw 63 to rotate in the opposite direction. The push plate 61 slides forward along the bottom side of the receiving hopper to reset to the initial position. The control box 2 then shuts off the motor 62.

[0062] After the processed aluminum profile is pushed out, motor 22 continues to drive the receiving rack 26 to rotate 45 degrees clockwise, so that the unloaded set of support rods is once again flush with the top surface of the loading rack 37. Motor 3 continues to drive the drive shaft 29 to rotate, so that the moving block 31 moves outward to the last half of the threaded sleeve 30. Screw 40 continues to rotate, driving the pusher 43 to move upward to the highest point, pushing the lifted aluminum profile completely past the receiving rack 38. The aluminum profile slides into the unloaded support rod of the receiving rack 26. Then the receiving rack 26 rotates 45 degrees counterclockwise to reset, and a new aluminum profile is transferred into the feeding channel. Motor 28 reverses, and moving block 31 drives limiting frame 34 to move closer to the aluminum profile, clamping and limiting the new aluminum profile in the feeding channel again. Pusher 43 moves down to reset to the bottom. The remaining aluminum profile on loading rack 37 slides down and is blocked again by abutting frame 38. Sliding rod 44 moves forward, and adjusting push rod 47 pushes the new aluminum profile to abut and position against calibration plate 52. At this point, the device completes a complete automatic processing cycle, and all components return to the initial state. Control box 2 can control each drive component to repeat the above actions to realize continuous automated milling operation.

[0063] When the debris inside the dust collection box 14 accumulates to the point where it needs to be cleaned, the operator can manually hold the rounded rectangular opening on the front of the baffle 15 and pull the baffle 15 outward from the material inlet on the top side of the dust collection box 14 to clean the debris trapped inside the dust collection box 14. After cleaning, the baffle 15 can be reinserted along the material inlet to reset its position. For larger debris collected in the waste frame 55, the operator can periodically pull the waste frame 55 out from the bottom inside the fixed housing 5 for cleaning. After cleaning, the waste frame 55 can be pushed back into the bottom inside the fixed housing 5.

[0064] Control box 2 is a PLC-based industrial controller. It stores the logic program that executes the above-mentioned workflow. By controlling the start, stop, direction and speed of each motor and electric slide rail, the automated operation of the equipment is realized. Those skilled in the art can write the corresponding control program based on the described action flow without creative labor.
