Description

Technical Field

[0001] This invention relates to the field of photovoltaic aluminum profile processing technology, and more specifically, to an automatic cutting device for photovoltaic aluminum profile processing. Background Technology

[0002] With the rapid development of the new energy industry, the application of solar photovoltaic power generation systems is becoming increasingly widespread. Photovoltaic modules are typically installed on outdoor rooftops or in open fields using aluminum alloy bracket arrays. Because photovoltaic brackets are exposed to the complex natural environment outdoors for extended periods, they must withstand enormous wind loads and dynamic alternating stresses from severe weather conditions such as strong winds and blizzards. Therefore, extremely high requirements are placed on their assembly strength and overall structural stability.

[0003] Currently, photovoltaic aluminum alloy brackets are mostly assembled from long, thin-walled aluminum profiles that have been sawn and cut. The dimensional accuracy, angular tolerance, and surface flatness of the profile cut sections directly determine the tightness of the fit during subsequent corner assembly. If the cutting accuracy is substandard, it will lead to assembly gaps and insufficient preload at the bracket joints, resulting in a significant decrease in the overall frame rigidity. In windy weather, brackets with assembly gaps are highly susceptible to structural damage such as high-frequency resonance, loosening of joints, and even tearing of connections.

[0004] However, existing aluminum profile cutting equipment still has significant shortcomings in actual processing. Because photovoltaic aluminum alloy supports are mostly thin-walled hollow structures with weak bending and torsional stiffness, the cutting and impact forces generated by the high-speed cutting of the circular saw blade easily cause high-frequency vibrations and localized elastic deformation in the stress areas of the profile. This vibration during processing not only severely damages the perpendicularity and smoothness of the cut surface, leading to dimensional deviations, but also easily produces burrs and collapsed edges at the cut, thus seriously affecting the final assembly quality and outdoor service life of the photovoltaic support.

[0005] Therefore, an automatic cutting equipment for photovoltaic aluminum profile processing is proposed. Summary of the Invention

[0006] To address the problems existing in the prior art, the purpose of this invention is to provide an automatic cutting device for photovoltaic aluminum profile processing, which can reduce the probability of vibration during the cutting process, thereby improving the flatness of the cut surface.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An automatic cutting equipment for processing photovoltaic aluminum profiles includes an operating table with a mounting frame on the operating table; A hydraulic cylinder is vertically mounted on the mounting frame, and a cutting assembly for cutting the workpiece by means of a rotating disc cutter is connected to the bottom of the output end of the hydraulic cylinder. A mounting plate is fixedly fitted on the output end of the hydraulic cylinder. At least two elastic buffer rods are vertically provided on the bottom wall of the mounting plate, and a pressure block is fixedly connected to the bottom end of each elastic buffer rod. The upper surface of the operating table is provided with a lower slot that matches the bottom contour of the aluminum profile to be cut, and a lower cutting slot is provided directly below the corresponding cutting component on the operating table. The lower surface of the pressure block is provided with an upper slot that matches the top contour of the aluminum profile to be cut; An inclined guide groove is provided on the lower surface of the mounting plate, and the top end of the elastic buffer rod is slidably embedded in the inclined guide groove; a reset elastic element is connected between the groove side end of the inclined guide groove and the top side wall of the elastic buffer rod. A through hole is provided on the side wall of the elastic buffer rod, and a guide rod parallel to the upper wall of the inclined guide groove is fixedly installed in the inclined guide groove, and the elastic buffer rod is slidably sleeved on the guide rod through the through hole.

[0009] Furthermore, the elastic buffer rod includes a hollow outer cylinder that is slidably disposed in an inclined guide groove and a plunger inner rod that is slidably inserted into the hollow outer cylinder, with a through hole opened on the hollow outer cylinder; A closed energy storage and compression chamber is formed between the hollow outer cylinder and the inner rod of the plunger. A guide chamber communicating with the energy storage and compression chamber is opened inside the pressure block. The outlet of the guide chamber is set towards the lower cutting groove.

[0010] Furthermore, rolling balls are evenly embedded on the inner wall of the pressure block near the cutting component.

[0011] Furthermore, a lubricating fluid chamber adjacent to the flow guiding cavity is also provided inside the pressure block, and a Venturi negative pressure hole is provided on the pressure block. The input end and output end of the Venturi negative pressure hole are connected to the lubricating fluid chamber and the flow guiding cavity, respectively.

[0012] Furthermore, the side wall of the pressure block near the cutting component has multiple mounting holes adapted to the ball bearings, and the side wall of the flow guide cavity has evenly distributed air channels extending to the bottom of each mounting hole.

[0013] Furthermore, polyurethane energy-absorbing pads are evenly installed on the sidewalls of the mounting holes.

[0014] Furthermore, an upwardly inclined baffle is fixedly provided on the top edge of the pressure block, and an air hole is opened on the air guiding cavity, with the outlet of the air hole set to fit against the inner wall of the baffle.

[0015] Furthermore, a flexible Teflon anti-scratch film for protecting the oxide layer on the surface of the photovoltaic aluminum profile is fixedly installed on the inner wall of the upper slot opened on the lower surface of the pressure block. The thickness of the flexible Teflon anti-scratch film is 1mm-3mm.

[0016] Furthermore, a pressurization chamber is provided on the flexible Teflon anti-scratch surface, and a pressurization tube is inserted into the side wall of the energy storage and compression chamber, with one end of the pressurization tube extending into the flow guiding chamber.

[0017] Furthermore, a one-way air intake valve is embedded in the side wall of the energy storage chamber, and a spring is installed between the inner rod of the plunger and the inner top wall of the hollow outer cylinder.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By utilizing the single downward stroke of the hydraulic cylinder and through the cooperation of the inclined guide groove and the elastic buffer rod, the vertical downward pressing action is converted into a constant flexible clamping force on the aluminum profile and a lateral clamping force on the cutting blade. This clamping mechanism can effectively absorb the high-frequency vibration generated during the high-speed cutting of photovoltaic thin-walled cavity profiles, maintain the stability of the running trajectory of the rotating disc cutter, eliminate burrs and edge collapse on the cut surface, and improve the flatness and perpendicularity of the cut surface.

[0019] (2) The equipment generates a high-pressure airflow in the same step of pressing down and accumulating power and cutting into the workpiece, and further combines the Venturi effect to self-absorb and atomize the lubricant and spray it out. It achieves simultaneous cooling, chip blowing and lubrication of the cutting contact area without the need for an additional independent external air source or water pump, which reduces the cutting friction resistance of the saw blade and avoids thermal deformation.

[0020] (3) The rigid sliding friction is transformed into smooth rolling contact. The high-pressure gas is drawn through the branch air channel to blow back the ball mounting hole in real time, which prevents the cutting chatter caused by tiny aluminum chips jamming the ball. At the same time, the micro-deformation of the energy-absorbing pad absorbs the high-frequency cutting resonance energy, avoiding the deformation of the cutting blade or the damage of the cutting edge caused by overheating or uneven force.

[0021] (4) The compressed gas generated simultaneously during cutting is used to inflate the pressure chamber inside the Teflon anti-scratch liner, causing it to expand slightly and adaptively fill the micro-gaps on the surface of the aluminum profile, eliminating local suspension and vibration under rigid clamping. At the same time, the guide baffle and exhaust hole form an outward blowing protective air curtain, which isolates the intrusion of splashed aluminum chips into the inclined guide slide, ensuring the smooth execution of the entire set of actions while protecting the oxide film on the surface of the workpiece without damage.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Example 1: Please see Figures 1 to 7 An automatic cutting equipment for processing photovoltaic aluminum profiles includes an operating table 1, on which a mounting frame 2 is provided; A hydraulic cylinder 3 is vertically mounted on the mounting bracket 2. The bottom of the output end of the hydraulic cylinder 3 is connected to a cutting assembly 4 for cutting the workpiece by a rotating disc cutter. The cutting assembly 4 includes a motor 401 fixedly mounted on the bottom of the output end of the hydraulic cylinder 3. A cutting blade 402 is fixedly mounted on the output end of the motor 401. A mounting plate 5 is fixedly sleeved on the output end of the hydraulic cylinder 3. At least two elastic buffer rods 6 are vertically provided on the bottom wall of the mounting plate 5, and a pressure block 7 is fixedly connected to the bottom end of each elastic buffer rod 6. The elastic buffer rods 6 are symmetrically distributed on both sides of the cutting assembly 4. The upper surface of the operating table 1 is provided with a lower slot 8 that matches the bottom contour of the aluminum profile to be cut, and a lower cutting slot 9 is provided on the operating table 1 directly below the cutting component 4. The lower surface of the pressure block 7 is provided with an upper slot 10 that matches the top contour of the aluminum profile to be cut; An inclined guide groove 11 is provided on the lower surface of the mounting plate 5, and the top end of the elastic buffer rod 6 is slidably embedded in the inclined guide groove 11; a reset elastic element 12 is connected between the groove side end of the inclined guide groove 11 and the top side wall of the elastic buffer rod 6. A through hole is provided on the side wall of the elastic buffer rod 6, and a guide rod 13 parallel to the upper wall of the inclined guide groove 11 is fixedly installed in the inclined guide groove 11, and the elastic buffer rod 6 is slidably sleeved on the guide rod 13 through the through hole. In the initial state, under the natural extension of the elastic buffer rod 6, the bottom horizontal height of the pressure block 7 is lower than the lowest point of the cutting blade 402 in the cutting assembly 4.

[0026] First, place the photovoltaic aluminum profile to be cut in the lower slot 8 of the operating table 1, and fix and limit the bottom and sides of the aluminum profile through the inner wall of the lower slot 8. Subsequently, the hydraulic cylinder 3 is activated, and its output end drives the mounting plate 5 and the cutting assembly 4 to extend downwards synchronously. During this descent, due to the height difference, the upper slot 10 on the pressure block 7 first contacts and fits against the top of the aluminum profile. At this time, the upper slot 10 and the lower slot 8 form a closed state, tightly wrapping and fixing the aluminum profile in all directions. Finally, the output end of the hydraulic cylinder 3 continues to extend downwards. At this time, the elastic buffer rod 6 is gradually compressed and continuously stores force, and the cutting blade 402 of the cutting assembly 4 gradually cuts into the aluminum profile. In the initial state, under the elastic support of the reset elastic element 12, the elastic buffer rod 6 is located at the lower end of the inclined guide groove 11. When the pressure block 7 is pressed against the aluminum profile and is resisted by force, and the elastic buffer rod 6 continues to move downwards, the elastic buffer rod 6 overcomes the elastic force of the reset elastic element 12 and slides to the higher end of the inclined guide groove 11, thereby converting into a lateral driving force that drives the pressure block 7 to make lateral displacement. This drives the two pressure blocks 7 to move towards the lower cutting groove 9 until the cutting blade 402 begins to cut the aluminum profile. The adjacent sidewalls of the two pressure blocks 7 dynamically adhere to the left and right sides of the cutting blade 402, providing lateral flexible clamping and shock absorption guidance for the high-speed rotating cutting blade 402, reducing the probability of aluminum profile vibration. Throughout the sawing process, the pressure block 7 continuously applies a constant clamping force to the aluminum profile under the reaction force of the compressed elastic buffer rod 6. This absorbs the high-frequency vibration and impact kinetic energy generated when the circular saw blade cuts thin-walled hollow profiles at high speed, eliminates the local elastic deformation and shaking of the aluminum profile, thereby ensuring the flatness and perpendicularity of the cut surface and preventing the generation of burrs and collapsed edges.

[0027] like Figure 2As shown, the elastic buffer rod 6 includes a hollow outer cylinder 601 that is slidably disposed in the inclined guide groove 11 and a plunger inner rod 602 that is slidably inserted into the hollow outer cylinder 601, with a through hole opened on the hollow outer cylinder 601. A closed energy storage and compression chamber is formed between the hollow outer cylinder 601 and the inner plunger rod 602. The pressure block 7 has a guide chamber 14 that communicates with the energy storage and compression chamber. An air pipe 1401 extending into the guide chamber 14 is fixedly inserted into the side wall of the energy storage and compression chamber, thereby connecting the energy storage and compression chamber with the guide chamber 14. The outlet of the guide chamber 14 is oriented towards the lower cutting groove 9. As the hydraulic cylinder 3 extends downward and the elastic buffer rod 6 is gradually compressed, the inner rod 602 of the plunger squeezes the air in the energy storage chamber, forcing the high-pressure airflow to be directed and sprayed through the guide chamber 14 to the cutting contact area between the cutting blade 402 and the aluminum profile. Thus, during the cutting process, the cutting blade 402 and the cutting area are cooled and chipped away simultaneously.

[0028] like Figure 4 , Figure 5 As shown, the inner wall of the pressure block 7 near the cutting component 4 is uniformly embedded with ball bearings 15; When the pressure block 7 provides lateral flexible clamping and guidance for the high-speed rotating cutting blade 402, the ball 15 makes rolling contact with the side end face of the cutting blade 402, thereby converting sliding friction into rolling friction, reducing the lateral frictional resistance of the cutting blade 402, and preventing the cutting blade 402 from deforming or chipping due to overheating and excessive wear.

[0029] like Figure 4 , Figure 6 As shown, the pressure block 7 also has a lubricating fluid chamber 27 adjacent to the guide cavity 14. The pressure block 7 has a Venturi negative pressure hole 16. The input end and output end of the Venturi negative pressure hole 16 are connected to the lubricating fluid chamber 27 and the guide cavity 14, respectively. When the high-pressure airflow is ejected at high speed through the guide cavity 14, a local negative pressure is generated at the Venturi negative pressure hole 16, which draws out the lubricating fluid in the lubricating fluid chamber 27 and atomizes it. It is then sprayed together with the high-pressure airflow onto the cutting contact surface between the cutting blade 402 and the aluminum profile, thereby lubricating the cutting area and reducing the cutting friction coefficient while suppressing cutting chatter.

[0030] like Figure 4 As shown, the side wall of the pressure block 7 near the cutting component 4 has multiple mounting holes 17 that are adapted to the ball 15, and the side wall of the guide cavity 14 has evenly provided air passages 18 that extend to the bottom of each mounting hole 17. When the high-pressure airflow enters, part of the airflow blows out the aluminum chips stuck in the gap between the ball 15 and the mounting hole 17 through the branch air passage 18, so as to ensure the smooth rolling of the ball 15 and prevent cutting chatter or scratching of the cutting blade 402 caused by the ball 15 getting stuck.

[0031] like Figure 5 As shown, polyurethane energy-absorbing pads 19 are uniformly installed on the side wall of the mounting hole 17; when the ball 15 comes into contact with the high-speed rotating cutting blade 402 and generates high-frequency vibration, the energy-absorbing pad 19 undergoes micro-elastic deformation to absorb the cutting resonance energy.

[0032] like Figure 4 , Figure 7 As shown, the top edge of the pressure block 7 is fixed with an upwardly inclined guide baffle 20, and the guide cavity 14 is provided with an air hole 21. The outlet of the air hole 21 is set to fit against the inner wall of the guide baffle 20; and the air hole 21 is located between the Venturi negative pressure hole 16 and the output end of the air pipe 1401. When the hydraulic cylinder 3 is pressed down and the elastic buffer rod 6 is compressed, some of the high-pressure airflow is ejected through the air hole 21 and forms a protective air curtain that blows outward and upward along the guide baffle 20 to prevent fine aluminum chips from splashing into the sliding gap between the inclined guide groove 11 and the elastic buffer rod 6, thereby ensuring that the elastic buffer rod 6 can work normally.

[0033] like Figure 7 As shown, a flexible Teflon anti-scratch patch 22 for protecting the oxide layer on the surface of photovoltaic aluminum profile is fixedly installed on the inner wall of the upper slot 10 opened on the lower surface of the pressure block 7. The thickness of the flexible Teflon anti-scratch patch 22 is 1mm-3mm, which can prevent the photovoltaic aluminum profile from being subjected to rigid friction, thereby preventing the aluminum profile surface from being scratched during the movement of the pressure block 7.

[0034] like Figure 4 As shown, a pressurizing chamber 23 is provided on the flexible Teflon anti-scratch surface 22, and a pressurizing tube 24 is inserted into the side wall of the energy storage and air compression chamber. One end of the pressurizing tube 24 extends into the flow guiding chamber 14. During the process of the plunger inner rod 602 extruding the energy storage chamber, some of the high-pressure gas in the energy storage chamber enters the pressurization chamber 23, which drives the flexible Teflon anti-scratch surface 22 to expand adaptively, so that the flexible Teflon anti-scratch surface 22 tightly fits the dimensional tolerance gap of the aluminum profile to be cut, thereby eliminating the vibration of the aluminum profile during the force cutting process.

[0035] like Figure 3As shown, a one-way air intake valve 25 is embedded in the side wall of the energy storage chamber, and a spring 26 is installed between the inner rod 602 of the plunger and the inner top wall of the hollow outer cylinder 601. Therefore, when the inner rod 602 of the plunger is not subjected to external force, the inner rod 602 of the plunger is in a state of extending out of the hollow outer cylinder 601. And when the inner rod 602 of the plunger extends out of the hollow outer cylinder 601, the energy storage chamber draws air from the outside through the one-way air intake valve 25 to prepare for the next operation.

[0036] like Figure 1 As shown, the tilt angle of the inclined guide groove 11 relative to the horizontal plane is set to 15°-30°. This angle range can ensure that the hydraulic cylinder 3 can press down smoothly while providing sufficient lateral force to drive the pressure block 7 to clamp the blade.

[0037] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
