Description

Technical Field

[0001] The invention relates to the technical field of aluminum door and window profile processing, in particular to an aluminum door and window profile sawing device. Background Art

[0002] Aluminum door and window profiles are commonly used processing materials in the construction industry. Their cutting accuracy and connection method directly affect the stability and aesthetics of the profiles after assembly. Existing traditional sawing equipment mostly uses a fixed-angle saw blade cutting method, mainly completing the splicing of profiles through 45° or 90° straight line cutting. In this way, when splicing profiles, additional connectors such as screws, angle brackets, and glue are required to complete the assembly. This not only increases the complexity of the splicing process, but also easily leads to poor stability of the assembled structure due to fatigue failure of the connectors, while affecting the overall strength and appearance of the aluminum profile.

[0003] In recent years, in order to improve the splicing strength and stability of aluminum profiles, methods of processing aluminum profile special-shaped ports using laser cutting or water jet cutting technology have gradually appeared on the market. This method uses high-precision cutting technology to process complex mortise and tenon connection structures at the ends of aluminum profiles, which can effectively integrate traditional mortise and tenon technology into aluminum profile splicing, reduce dependence on connectors, and thus improve the overall stability and durability of the assembly. In addition, the addition of the mortise and tenon structure also enhances the aesthetics of the profile after assembly, avoiding surface damage caused by connection methods such as screws or glue.

[0004] However, this method of processing the mortise and tenon joint structure by laser cutting or water jet cutting technology still has the following defects: The processing equipment is costly and consumes a lot of energy: Laser cutting equipment and water jet cutting equipment are expensive, and consume a lot of energy during high-precision cutting, which is not conducive to the economic needs of large-scale processing scenarios.

[0005] High maintenance cost and complex operation: Laser equipment requires regular replacement of the light source and cutting head, and water jet cutting requires frequent maintenance of the high-pressure water pump and abrasive system. These increase the maintenance cost of the equipment and require high professional skills of the operator.

[0006] Low cutting efficiency: The processing speed of laser cutting and water jet cutting is slow when processing thick-walled or high-strength aluminum profiles, which is difficult to meet the needs of mass production.

[0007] Strong material restrictions: Abrasives and cooling water are required during water jet cutting, which can easily cause contamination to the surface of aluminum profiles, while laser cutting has high requirements on the reflective properties of the material, resulting in unstable cutting efficiency and quality.

[0008] Therefore, there is an urgent need in the prior art for an efficient sawing device that is economical, easy to maintain, and adaptable to the processing needs of complex mortise and tenon structures, to replace laser or water jet cutting methods and meet the widespread needs of mortise and tenon connection processing of aluminum door and window profiles. The present invention overcomes many defects of traditional laser or water jet cutting through innovative sawing technology and modular design, and provides an efficient and reliable solution for the processing of special-shaped ports of aluminum door and window profiles. Summary of the invention

[0009] To achieve the above-mentioned purpose, the present invention provides a sawing device for aluminum door and window profiles, which mainly includes a sawing assembly, a multi-bearing platform and a tooling assembly. Each part works together to achieve high-precision special-shaped end processing and mortise and tenon joint processing of profiles. The specific structure and function design are as follows: 1. Sawing components The sawing assembly is used to drive the saw rope to run at high speed and cut, and its structural design is as follows: Driving wheel and tension wheel: The driving wheel is driven by the driving unit to achieve high-speed rotation, thereby driving the saw rope to run at high speed along a fixed path. The tension wheel forms a tension adjustment mechanism with the driving wheel through the screw adjustment assembly, which can dynamically adjust the tension of the saw rope to ensure stability and cutting quality during the sawing process.

[0010] Saw rope: The saw rope is made of special high-strength metal wire material, with meshing wire groove design on the surface, which can adapt to saw ropes of different diameters. The saw rope running at high tension and high speed has excellent cutting ability, and can process complex special-shaped ports to meet the processing requirements of mortise and tenon joints.

[0011] Guide: The guide limits the saw rope horizontally and vertically through the guide wheel and the limit wheel group to prevent the saw rope from deviating during high-speed operation and ensure accurate cutting path. The guide is equipped with an internal cooling channel to guide the coolant to cool and lubricate the saw rope, avoid high temperature affecting the cutting performance, and extend the service life of the saw rope.

[0012] Drive unit: The drive unit provides the power source for the saw rope and can realize the high-speed rotation of the driving wheel. Through the control of the CNC center, the drive unit can adjust the speed and operation mode of the saw rope according to the processing requirements to adapt to the processing of different materials and complex structures.

[0013] 2. Multi-bearing table The multi-bearing table is used to adjust the relative position and movement angle between the profile and the saw rope to meet the processing requirements of complex ports. Its structural design is as follows: Cap seat: As the main structure of the multi-bearing table, the cap seat is fixed on the screw guide rail and can be precisely moved by the control of the CNC center. The screw guide rail allows the cap seat to slide in both directions along the horizontal and vertical axes to position the profile to the best position in the sawing area.

[0014] Support arm and support foot: The support arm and support foot are used to support and adjust the angle and position of the profile, and the first and second steering gears control their angle deflection respectively. The first steering gear connects the support arm to control its tilt angle with the support base; the second steering gear realizes multi-angle adjustment of the support foot through the crank connecting rod and the eccentric sleeve. The support foot can change the relative movement angle between the profile and the saw rope, thereby supporting the processing of complex special-shaped ports.

[0015] Linking rod: The connecting rod is used to realize the synchronous linkage of the support foot and the support arm. The connection point is arranged eccentrically to ensure that the angle adjustment of the support foot is coordinated with the movement of the support arm, thereby improving the support stability.

[0016] 3. Tooling components The tooling components are used to accurately clamp and position profiles to ensure stability and accuracy during processing. Its structural design is as follows: Positioning box: The positioning box is the fixed base of the tooling assembly and is connected to the pedestal seat. A box cover is provided on its surface to protect the internal structure and provide rigid support for the tooling as a whole.

[0017] Fixed ring disc and moving ring disc: The fixed ring disc is fixedly installed inside the positioning box, and the moving ring disc can rotate relative to the fixed ring disc under the action of the driving rod. The rotation angle of the moving ring disc is precisely controlled by the CNC center to meet different processing requirements.

[0018] Chuck ears: The chuck ears are evenly distributed between the fixed ring disc and the movable ring disc, and through the cooperation of the straight slide groove and the arc slide groove, synchronous movement in the radial and deflection directions is generated. The chuck ears can quickly clamp and accurately position the profile, and adjust the clamping force and position according to the specifications of the profile to ensure the stability of the profile during the cutting process.

[0019] Driving rod: The driving rod is used to drive the rotation of the moving ring disc, thereby controlling the sliding trajectory of the chuck ear to complete the clamping and releasing operations of the profile.

[0020] 4. CNC control system The entire device is intelligently controlled by the CNC center, and its main functions include: Path planning: Automatically generate sawing paths based on input profile dimensions and processing requirements, and coordinate control of sawing components, multi-bearing tables and tooling components.

[0021] Real-time monitoring and feedback: Equipped with sensors to monitor the saw wire running status and profile position during the cutting process. When abnormalities are found, the cutting path is adjusted in time to ensure processing accuracy.

[0022] Parameter setting: Users can set parameters such as cutting speed, saw wire tension, profile clamping position, etc. to adapt to different materials and complex processing requirements.

[0023] Through the above technical solution, the present invention provides an efficient, precise and easy-to-maintain aluminum door and window profile sawing device. The sawing assembly, multi-bearing platform and tooling assembly cooperate with each other, which can not only realize high-precision processing of complex mortise and tenon structures, but also significantly improve the processing efficiency and applicability of the equipment, meeting the diversified needs of modern aluminum profile processing.

[0024] The beneficial effects achieved by the present invention are: 1. In the present invention, the relative movement angle between the profile and the saw rope can be changed through the multi-angle adjustment function of the support arm and the support leg, so as to realize the sawing of complex special-shaped ports, and can process a variety of mortise and tenon joint surfaces to meet the complex connection requirements of aluminum door and window profiles.

[0025] 2. In the present invention, the saw rope is made of special high-strength metal wire, and the surface is matched with a meshing wire groove design. It has excellent cutting ability under high tension and high-speed operation, which significantly improves the cutting efficiency.

The chuck ear clamps the profile, and adjusts the clamping force and position according to the processing requirements to ensure the stability of the profile during the cutting process.

[0047] The working principle and use process of the present invention: 1.

[0048] Guide 230: The guide wheel 233 and the limit wheel group 234 in the guide limit the saw rope horizontally and vertically to prevent the saw rope from deviating and improve the cutting accuracy. The coolant in the guide is cooled by the inner cooling channel 232 to effectively reduce the working temperature of the saw rope and extend its service life.

[0049] Saw rope 240: It is made of special high-strength metal wire, and the surface is matched with meshing wire groove design. It can adapt to saw ropes of different diameters and maintain cutting sharpness during high tension and high-speed operation.

[0050] 2. Working principle of multi-bearing table The pedestal seat 310 is used as a carrier of the entire tooling and support system, fixed on the screw guide rail 110, and automatically positioned by the CNC center 120.

[0051] The support arm 320 and the support leg 330: The first servo 311 and the second servo 312 respectively control the angle deflection of the support arm 320 and the support leg 330, and the crank connecting rod 313 and the eccentric sleeve 314 are linked to realize multi-angle adjustment of the support leg, thereby changing the relative movement angle of the profile and the saw rope 240, realizing the sawing of special-shaped surfaces, and processing various mortise and tenon connection surfaces.

[0052] Linking rod 331: used for linkage between the support leg 330 and the support arm 320, and the connection point is eccentrically arranged to achieve angular deflection linkage.

[0053] 3. Working principle of tooling components: Positioning box 410: as a fixed base of the tooling module, connected to the support base 310. Its surface is protected by a box cover 411 to protect the internal structure.

[0055] The clamping head ear 440 slides between the moving ring disk and the fixed ring disk, and through the cooperation of the straight slide groove 421 and the arc slide groove 431, generates synchronous movement in the radial and deflection directions, thereby realizing rapid clamping and precise positioning of the profile.

[0056] Driving rod 450: used to drive the rotation of the dynamic ring disk 430, so as to control the strength and position of the clamping ear 440 to clamp the profile.

[0057] Usage Process Step 1: Place the aluminum door and window profile on top of the multi-bearing platform 300 and perform preliminary positioning and clamping by the clamping ear 440 of the tooling assembly 400. Input the profile size, cutting position and angle in the CNC center 120 to generate cutting path data.

[0058] Step 2: Control the support seat 310 to move along the guide rail to the cutting area through the screw guide rail 110.

The distance between the tension wheel 212 and the driving wheel 211 is adjusted through the screw adjustment assembly to optimize the saw rope tension. The internal cooling channel 232 is started, and the coolant is sprayed onto the surface of the saw rope through the guide 230 to reduce heat accumulation during the cutting process.

[0060] Step 4: If bevel cutting or special-shaped cutting is required, the first servo 311 and the second servo 312 are used to adjust the inclination angle of the support leg 330 and the sawing path to achieve complex angle cutting. The sensor monitors the running state of the saw rope and the position of the profile during the cutting process. If a deviation is found, the CNC center automatically adjusts the cutting path.

[0061] After the cutting is completed, the sawing assembly stops running, and the tooling chuck ear 440 releases the profile. The multi-bearing platform 300 pushes the profile out of the cutting area to prepare for the next processing step.

[0062] The invention realizes efficient and high-precision sawing of aluminum door and window profiles through the coordinated work of sawing components, multi-bearing platforms and tooling components.
