Description

Technical Field

[0001] This utility model relates to the technical field of aluminum door and window processing equipment, and in particular to an automatically rotating aluminum profile sawing support. Background Technology

[0002] The first step in the deep processing of aluminum door and window profiles, curtain wall profiles, etc., is often fixed-length cutting and multi-angle cutting. The CNC equipment used in this process is typically a CNC double-head cutting saw, a common product in the aluminum machinery industry, widely used for fixed-length sawing of aluminum door and window profiles. In actual cutting, the left head is fixed, while the right head moves to the cutting position via servo control. After the initial profile is placed on the cutting table, it is pneumatically positioned and clamped, and then cut simultaneously by both heads to complete the fixed-length, fixed-angle cutting. However, due to the increasingly larger market requirements for door and window specifications, i.e., longer cutting dimensions, coupled with the comprehensive cutting requirements for curtain wall materials, the length and weight of the profiles have also increased. Traditional manual material support methods can no longer meet the demands for efficient and safe production. While traditional material support frames can provide some support, they interfere with the movement of the cutting head. When cutting longer profiles, operators need to frequently move the material support frame, which is not only labor-intensive but also poses safety hazards, easily causing scratches on the profiles or damage to the equipment, affecting the overall processing efficiency and automation level of the equipment. Therefore, there is an urgent need for a material support structure that can automatically rotate and adapt to various profile specifications in order to improve the stability and production efficiency of cutting operations. Utility Model Content

[0003] To address the issue of automatic support for aluminum profile sawing processes such as CNC double-head cutting saws, and to prevent work efficiency and processing quality from being affected by excessively long or heavy profiles or manual intervention, this utility model provides an automatically rotating aluminum profile sawing support rack.

[0004] The present invention provides an automatically rotating aluminum profile sawing support rack, which adopts the following technical solution:

[0005] An automatically rotating aluminum profile sawing support includes a CNC double-head cutting saw and a rotating support assembly. The rotating support assembly includes several support devices, each of which includes a mounting frame. A rotational power component is fixedly connected inside each mounting frame. A support structure is rotatably connected to the top of each mounting frame. The output end of each rotational power component is drivenly connected to the bottom of the corresponding support structure. The several mounting frames are arranged linearly and installed on both sides of the CNC double-head cutting saw by bolts and nuts. The several rotational power components are communicatively connected to the CNC double-head cutting saw.

[0006] By adopting the above technical solution, the number of material support devices is not fixed. Based on the needs of the profile, the material support devices are automatically rotated according to the program, and the number can be flexibly arranged. During material support, the material support is automatically rotated to a certain position according to the position of the moving head, avoiding interference with the moving head. This can effectively support the profiles during cutting processes such as double-head cutting saws, preventing the profiles from being too long or too heavy and deforming, which would affect the cutting accuracy and quality. At the same time, it can effectively avoid manual intervention, which would affect the processing efficiency.

[0007] Preferably, each of the rotating power components includes a rotary cylinder, a cylinder mounting bracket, and a rod end bearing. One end of the rotary cylinder is fixedly connected to the bottom end of the cylinder mounting bracket, the top of the cylinder mounting bracket is fixedly connected to the inner wall of the mounting bracket, and the other end of the rotary cylinder is fixedly connected to one end of the rod end bearing.

[0008] Preferably, each of the material support structures includes a rotating crankshaft, a column, and a roller. The top of each rotating crankshaft is fixedly connected to the bottom of the column, and the bottom of each rotating crankshaft is keyed to the inside of the rod end bearing.

[0009] Preferably, each of the columns is radially connected to a column bearing at its top, and each column bearing is keyed to a rotating rod, which is in the shape of a mirror L.

[0010] Preferably, each of the rotating crankshafts includes two vertical rods and a connecting plate, wherein a portion of the vertical rods are fixedly connected to the upper part of one end of the corresponding connecting plate, and the other portion of the vertical rods are fixedly connected to the lower part of one end of the corresponding connecting plate.

[0011] Preferably, each of the mounting brackets has a limiting block fixedly connected inside, and each limiting block is located on one side of the corresponding rotating crankshaft, with the bottom of the limiting block flush with the bottom of the rotating crankshaft connecting plate.

[0012] By adopting the above technical solution, the rotating material support assembly on the left side of the moving head performs a lifting action under system control. The rotating cylinder retracts and drives the rotating crankshaft to rotate to the limit block position through the rod end bearing, so that the roller assembly rotates 90° under the drive of the rotating rod to the material support position.

[0013] Preferably, one end of the rotating rod crossbar is detachably connected to a roller.

[0014] By adopting the above technical solution, it is convenient to replace the roller.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] 1. This device is equipped with a CNC double-head cutting saw and a rotary material support assembly, which can effectively support the profiles during cutting processes such as double-head cutting sawing. This prevents the profiles from being too long or too heavy, which could cause deformation and affect cutting accuracy and quality. Based on the position of the moving head and the size of the profile, the system automatically determines whether the rotary material support assembly should be used. This ensures effective material support and avoids the impact of excessively long or heavy profiles or manual intervention on work efficiency and processing quality. It effectively reduces manual intervention and minimizes human resource consumption.

[0017] 2. This device is equipped with several material support devices. Compared with the CNC double-head cutting saw system, the number can be flexibly arranged. During material support, the device automatically rotates to a certain position according to the position of the moving head to avoid interference with the moving head. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0024] This utility model discloses an automatically rotating aluminum profile sawing support rack.

[0025] Reference Figure 1 , Figure 2 , Figure 4The system includes a CNC double-head cutting saw 1 and a rotary material support assembly 2. The rotary material support assembly 2 includes several material support devices, each of which includes a mounting frame 3. A rotating power component is fixedly connected inside each mounting frame 3. A material support structure is rotatably connected to the top of each mounting frame 3. The output end of each rotating power component is driven to the bottom of the corresponding material support structure. The several mounting frames 3 are arranged linearly and installed on both sides of the CNC double-head cutting saw 1 by bolts and nuts. The several rotating power components are all communicatively connected to the CNC double-head cutting saw 1.

[0026] The right head of the CNC double-head cutting saw 1 is CNC moved to the position of the required material cutting size. The rotating material support assembly 2 on the left side of the moving head performs a lifting action under the system control. The rotating cylinder 4 retracts and drives the rotating crankshaft 7 to rotate to the position of the limit block 8 through the rod end bearing 5. This causes the roller 12 to rotate 90° under the drive of the rotating rod 11 and be in the material support position.

[0027] Place the profile on the left and right worktables of the CNC double-head cutting saw 1, with the center of the profile contacting the roller 12 in the rotating material support assembly 2, and position the profile backward and press it firmly.

[0028] The CNC double-head cutting saw 1 is set to perform the cutting action. When changing the cutting size, the system determines which rotating material support assembly 2 will perform the material support action, and pushes out the assemblies that do not need to participate in the material support action through the rotary cylinder 4 and retracts the roller 12 to avoid the automatic length-fixing operation of the moving head. Then, under the control of the system, the right head of the CNC double-head cutting saw 1 automatically moves to the fixed length and waits for material to be loaded. The above actions are repeated until the processing is completed.

[0029] Reference Figure 1 , Figure 2 , Figure 3 Each rotating power assembly includes a rotary cylinder 4, a cylinder mounting bracket 6, and a rod end bearing 5. One end of the rotary cylinder 4 is fixedly connected to the bottom end of the cylinder mounting bracket 6, the top of the cylinder mounting bracket 6 is fixedly connected to the inner wall of the mounting bracket 3, and the other end of the rotary cylinder 4 is fixedly connected to one end of the rod end bearing 5.

[0030] Reference Figure 1 , Figure 2 Each material support structure includes a rotating crankshaft 7, a column 9, and a roller 12. The top of each rotating crankshaft 7 is fixedly connected to the bottom of the column 9, and the bottom of each rotating crankshaft 7 is keyed to the inside of the rod end bearing 5. Under the restriction of the limiting block 8, the rotating crankshaft 7 allows the column 9 to drive the rotating rod 11 to rotate at an angle, so that the roller 12 can rotate within a 90° angle, instead of rotating 360° without restriction.

[0031] Reference Figure 1 , Figure 2Each column 9 has a radially connected column bearing 10 at its top, and each column bearing 10 has a keyed rotating rod 11 inside. The rotating rod 11 is in the shape of a mirrored L, that is, the lower L in the upper and lower mirrors. The rotation of the column 9 can drive the rotating rod 11 to rotate 90° from the top view angle with the vertical rod as the center and the horizontal rod as the radius.

[0032] Reference Figure 2 Each rotary crankshaft 7 includes two vertical rods and a connecting plate. Some of the vertical rods are fixedly connected to the top of one end of the corresponding connecting plate, and the other part of the vertical rods are fixedly connected to the bottom of one end of the corresponding connecting plate. The extension and retraction of the output end of the rotary cylinder 4 drives the displacement of the rod end bearing 5. Due to the connection limit of the rotary crankshaft 7, the linear motion driven by the rotary cylinder 4 is converted into the rotational motion of the column 9, which in turn drives the rotary rod 11 to rotate. This allows the roller 12 to adapt to different specifications of profiles such as aluminum doors and windows and curtain walls. Based on the position of the moving head on the CNC double-head cutting saw 1, the profile size system automatically determines whether the rotary material support assembly 2 is working.

[0033] Reference Figure 1 , Figure 2 Each of the mounting brackets 3 has a fixedly connected limit block 8 inside. Each limit block 8 is located on one side of the corresponding rotating crankshaft 7, and the bottom of the limit block 8 is flush with the bottom of the connecting plate of the rotating crankshaft 7.

[0034] One end of the rotating rod 11 is connected to the roller 12 by conventional threaded connection, plug-in or other detachable means. When the roller 12 is worn to the point of being unusable, it can be removed and replaced with a new roller 12.

[0035] The implementation principle of the automatically rotating aluminum profile sawing support rack in this embodiment of the utility model is as follows:

[0036] The rotating crankshaft 7 is driven to rotate by the rotating cylinder 4, and the rotation is performed by the column bearing 10 in the column 9. The process principle is that when the moving head of the CNC double-head saw moves automatically, no manual intervention is required. The system judges and performs the sawing and lifting work of the profile. (That is, when the moving head moves, the system judges and executes different rotating material support assemblies 2 according to the length of the profile, ensuring that the material support assembly between the fixed head and the moving head is in working condition.) This ensures that deformation caused by factors such as excessive length or weight of the profile does not affect the processing accuracy and quality.

[0037] The rotary cylinder 4 can be a cylinder with servo feedback, which makes it easier for the CNC double-head saw to move the machine head to make judgments based on the servo feedback and adjust in time to perform the sawing and lifting work of the material.

[0038] Install the roller 12 onto the rotating rod 11, install the column bearing 10 into the column 9, and install the column 9 onto the mounting bracket 3. Assemble the roller 12 and rotating rod 11 assembly into the column 9 and lock it. Install the cylinder mounting bracket 6 and the limit block 8 onto the mounting bracket 3 respectively. Connect the rod end bearing 5 to the rotating cylinder 4 and install it onto the cylinder mounting bracket 6. Install the rotating crankshaft 7 onto the lower end of the rotating rod 11 and fix it to the rod end bearing 5. Install the above-mentioned rotating material support assembly 2 onto the CNC double-head cutting saw 1 and install the air circuit and electrical circuit.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
