Description

Technical Field

[0001] This utility model relates to the technical field of profile processing equipment, specifically a long material double-head sawing machine. Background Technology

[0002] With the increasing demands for processing precision and capacity of long materials (such as aluminum alloy profiles) in industries such as building materials, furniture, and rail transportation, there is an urgent need for efficient equipment capable of simultaneously sawing both ends. Double-head sawing machines, by simultaneously sawing from both ends, can reduce the number of clamping operations, shorten auxiliary time, and significantly improve processing efficiency and cut quality, making them an important piece of equipment in the mass production of long materials.

[0003] For example, utility model application CN202221773938.3 discloses a double-head sawing device. This utility model employs a double-head sawing structure, where sawing machines are symmetrically arranged on both sides of the fixed structure of the workpiece to be sawed. This allows for double-end sawing of the workpiece without needing to flip it over, resulting in high sawing efficiency. However, it requires manual positioning of long materials, which is not only labor-intensive but also prone to quality problems such as burrs and tilting at the cut due to operational errors.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a long material double-head sawing machine. Utility Model Content

A horizontal worktable is fixed below the surface of the machine housing, and an mounting plate is fixed above the surface of the machine housing. A servo motor is mounted at the top center of the mounting plate, and the output end of the servo motor is connected to a drive shaft. A drive gear is sleeved on the outside of the drive shaft, and driven gears 1 and 2 are respectively connected to the outside of the drive gear.

Cylinder 1 and Cylinder 2 are respectively mounted on the mounting plate, and the output ends of cylinders 1 and 2 are connected to a horizontal support.

[0007] Furthermore, the horizontal worktable, mounting plate, and pressure plate are parallel to each other, and cylinder one and cylinder two are symmetrically distributed about the vertical central axis of the mounting plate.

[0008] Furthermore, the drive shaft and the lead screw are parallel to each other, and there are two lead screws and two lead screw nuts.

[0009] Furthermore, the lead screw is vertically inserted into the bearing at the through hole at the top of the housing, and a bearing is also provided at the through hole on the left side of the horizontal support.

[0010] Furthermore, a second servo motor is installed on the inner wall of the horizontal support, and the output end of the second servo motor is connected to a second lead screw, which is transversely inserted into the bearing at the through hole on the left side of the horizontal support.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 3 As shown, a long material double-head sawing machine includes a housing 1 and an anti-slip silicone pad 13. A horizontal worktable 2 is fixed below the surface of the housing 1, and a mounting plate 3 is fixed above the surface of the housing 1. A servo motor 4 is mounted on the top center of the mounting plate 3, and the output end of the servo motor 4 is connected to a drive shaft 5. A drive gear 6 is sleeved on the outside of the drive shaft 5, and driven gears 7 and 8 are respectively connected to the outside of the drive gear 6. A lead screw 9 is passed through the middle of both driven gears 7 and 8, and a lead screw nut 10 is connected to the outside of the lead screw 9. A pressure plate 11 is connected to the outside of the lead screw nut 10, and a pressure sensor 12 is installed in the groove at the bottom of the pressure plate 11. The anti-slip silicone pad 13 is provided with... Bearings 14 are provided at the through holes at the top of the machine housing 1 on the upper surface of the horizontal worktable 2 and the lower surface of the pressure plate 11. The horizontal worktable 2, the mounting plate 3 and the pressure plate 11 are parallel to each other, and cylinder 15 and cylinder 16 are symmetrically distributed about the vertical central axis of the mounting plate 3. The drive shaft 5 and the lead screw 9 are parallel to each other, and there are two lead screws and two lead screw nuts 10. The lead screw 9 is vertically inserted into the bearing 14 at the through hole at the top of the machine housing 1. A bearing 14 is also provided at the through hole on the left side of the horizontal support 17. A servo motor 18 is installed on the inner side wall of the horizontal support 17, and the output end of the servo motor 18 is connected to a lead screw 19. The lead screw 19 is horizontally inserted into the bearing 14 at the through hole on the left side of the horizontal support 17.

[0020] The specific operation is as follows: the horizontal worktable 2, the mounting plate 3 and the pressure plate 11 are parallel to each other. The servo motor 4 drives the drive gear 6 to drive the driven gear 7 and driven gear 8, which in turn drive the two lead screws 9 to rotate synchronously, so that the pressure plate 11 can be raised and lowered smoothly. The pressure sensor 12 at the bottom of the pressure plate 11 monitors the clamping force in real time to prevent over-clamping and damage to long materials or loosening of the clamps, which would cause sawing wobbling. This reduces the burr rate of the cut and reduces the need for subsequent grinding processes.

[0021] like Figure 1 and Figure 4 As shown, cylinder 15 and cylinder 2 16 are respectively mounted on mounting plate 3, and the output ends of cylinder 15 and cylinder 2 16 are connected to horizontal bracket 17. Screw 2 19 is externally connected to screw nut 20, and mounting base 21 is mounted on the outside of screw nut 20. Servo motor 3 22 is mounted on mounting base 21. The output end of servo motor 3 22 is connected to drive shaft 23, and saw blade 24 is mounted on the outside of drive shaft 23. Laser displacement sensor 25 is mounted on mounting base 21 on the left side, and laser displacement sensor 25 is electrically connected to controller 26. Controller 26 is electrically connected to servo motor 4, pressure sensor 12, cylinder 15, cylinder 2 16, servo motor 2 18, and servo motor 3 22.

[0022] The specific operation is as follows: Cylinder 15 and Cylinder 26 are symmetrically distributed, driving the horizontal support 17 to move synchronously, ensuring the lifting and lowering balance of the sawing mechanism. In conjunction with servo motor 322, drive drive shaft 23, which drives saw blade 24 to rotate at high speed, achieving stable sawing with both heads, high cut perpendicularity and few burrs. Moreover, controller 26 coordinates the work of servo motor 14, pressure sensor 12, cylinder 15, cylinder 26, servo motor 28 and servo motor 32, making the clamping force and sawing speed intelligently controllable, reducing manual intervention and labor intensity.

[0023] In summary, when using this long material double-head sawing machine, the long material (such as aluminum alloy profile) is first placed on the horizontal worktable 2. The controller 26 outputs a control signal to the servo motor 18 according to the target sawing length of the long material. The servo motor 18 drives the lead screw 19 to rotate, so that the lead screw nut 20 drives the mounting base 21 to move towards or away from each other along the axial direction of the lead screw 19. During the movement of the mounting base 21, the laser displacement sensor 25 on the left mounting base 21 detects the distance between the left and right mounting bases 21 in real time and feeds the detection data back to the controller 26. The controller 26 performs closed-loop adjustment according to the feedback until the distance reaches the set value, so as to achieve precise positioning of the sawing position. After positioning is completed, the controller 26 instructs the servo motor 4 to start. Its output drives the drive gear 6 to rotate through the drive shaft 5. The drive gear 6 simultaneously meshes with the driven gear 7 and the driven gear 8, causing the two lead screws 9 to rotate synchronously. Through the lead screw nut 10, the pressure plate 11 moves down along the lead screw 9 towards the horizontal worktable 2 until the upper and lower anti-slip silicone pads 13 clamp the long material. At the same time, the pressure sensor 12 detects the clamping force. After reaching the preset value, it feeds back to the controller 26, and the servo motor 4 stops, completing the stable clamping. Then, the controller 26 synchronously starts cylinder 15, cylinder 26 and servo motor 32 on both sides. Through the output of cylinder 15 and cylinder 26, the horizontal support 17 is pushed down, so that the saw blade 24 contacts the long material. In conjunction with the servo motor 322, the drive shaft 23 and the saw blade 24 are driven to rotate at high speed, so as to achieve synchronous sawing of both ends of the long material. After sawing is completed, the controller 26 instructs the servo motor 22 to stop, the cylinder 15 and cylinder 2 16 drive the horizontal support 17 to move upward and reset, the servo motor 4 reverses to drive the pressure plate 11 to rise and release the long material, and finally the servo motor 2 18 drives the saw blade 24 to reset.
