[0002] Metal materials for doors and windows are divided into steel door and window materials and aluminum alloy door and window materials. Compared with wooden doors and windows, metal doors and windows have less deformation, good durability, less shading, but high thermal conductivity. Compared with traditional wooden doors and windows, metal doors and windows require the use of mechanical processing equipment during processing to facilitate cutting or cutting operations. In the existing processing and cutting of metal doors and windows, circular saws are generally required to process the door and window workpieces. During the cutting process of existing circular saws, the operator needs to hold the workpiece to ensure the stability of the cutting. However, the cutting of the circular saw will cause the workpiece to vibrate slightly, which will cause the operator to hold it unstable, which will cause the workpiece to tilt and cause cutting failure. At the same time, when the operator holds the workpiece for cutting, a large amount of high-temperature metal debris will be generated at the contact position between the circular saw and the workpiece. These metal debris are very easy to splash onto the operator, which is very dangerous. Summary of the invention

[0030] Example 1

[0031] See also Figure 1-Figure 7As shown, the purpose of this embodiment is to provide a metal door and window cutting equipment, including a base 3, which is a supporting structure of the entire metal door and window cutting equipment, and is used to place and fix the equipment. The door and window workpiece is placed above the base 3, and the base 3 ensures the stability of the equipment and the safety of operation. A cutting component 1 is arranged above the base 3, and the cutting component 1 is the core part of the metal door and window cutting equipment, which is responsible for cutting the door and window workpiece. The cutting component 1 swings toward the door and window workpiece and cuts the door and window workpiece. By controlling the precise swing and cutting of the cutting component 1, precise processing of the door and window workpiece is achieved, and production efficiency and product quality are improved. Two clamping components 2 are arranged below the cutting component 1. The clamping components 2 are used to stably clamp the door and window workpiece during the cutting process to ensure that the workpiece does not move during the cutting process, thereby improving processing accuracy and operational safety. An eighth connecting rod 5 is arranged between the components 2. Through the two eighth connecting rods 5, the two clamping components 2 can synchronously fix the two ends of the door and window workpiece, thereby improving the response speed and processing accuracy of the equipment and reducing the processing error caused by the incoordination of components. When the eighth connecting rod 5 swings, it drives the two clamping components 2 to slide on the surface of the base 3 to clamp the door and window workpiece, thereby saving the process of manually fixing the door and window workpiece and effectively improving the processing efficiency of the door and window workpiece. A connecting piece 6 is arranged on one side of the eighth connecting rod 5. When the cutting component 1 swings, one end of the connecting piece 6 is squeezed so that the other end of the connecting piece 6 squeezes the eighth connecting rod 5. The force is transmitted by squeezing the connecting piece 6, so that the eighth connecting rod 5 can drive the clamping component 2 to perform the clamping action, realize precise force transmission and clamping control, and improve the stability and safety during the processing.

[0032] The cutting assembly 1 includes a blade 15, which is the core part of the cutting assembly 1 and is responsible for directly contacting and cutting the door and window workpiece. A baffle shell 11 is fixedly sleeved above the blade 15. The baffle shell 11 reduces the vibration of the blade during the cutting process, improves the cutting accuracy, and protects the operator from being hurt by flying metal fragments. A protective shell 12 is fixedly installed on one side of the baffle shell 11. A motor is installed inside the protective shell 12. The protective shell 12 provides additional safety protection, reduces pollution in the working environment, and protects the motor from corrosion. The motor drives the blade 15 to rotate. The motor is the power source for driving the blade 15 to rotate. The high-speed rotation of the motor drives the blade 15 to cut metal doors and windows. The choice of the motor directly affects the cutting speed and efficiency. The high-performance motor can provide stable speed and torque to ensure the continuity and uniformity of the cutting process.

[0033] Both sides of the retaining shell 11 are fixedly connected with a first connecting rod 13, and the first connecting rod 13 connects the retaining shell 11 with other mechanical parts to ensure the stability of the cutting assembly 1. Through the fixed connection, the overall rigidity of the cutting assembly 1 is improved, and the vibration that may occur during the cutting process is reduced, thereby improving the cutting accuracy. The end of the first connecting rod 13 away from the blade 15 is set to be a cam with a sharp top and a wide bottom. The design of the cam enables it to produce a specific motion trajectory when rotating, and converts rotational motion into linear motion. This design allows the cutting assembly 1 to achieve a more complex motion mode during the cutting process and can adapt to door and window workpieces of different shapes and sizes. A handle 16 is fixedly connected to the side of the protective shell 12 away from the first connecting rod 13. The handle 16 is used to operate and control the movement of the cutting assembly, which is convenient for the user to adjust during the cutting process and provides convenient operation, allowing the operator to control the cutting process more flexibly, improving work efficiency and safety. The handle 16 swings downward to drive the two The first connecting rod 13 rotates around the protective shell 12, and the first connecting rod 13 is driven to rotate around the protective shell 12 by swinging the handle 16, thereby realizing the cutting action of the blade. This mechanism makes the cutting action smoother and more controllable, reduces the instability in the cutting process, and ensures the cutting quality. The wider end of the cam swings downward, and this extrusion force can effectively push the connecting member 6, thereby clamping and fixing the workpiece, ensuring that the workpiece will not move during the cutting process. The connecting member 6 is arranged below the cam. The connecting member 6 acts as a follower, interacts with the cam, and receives the movement generated by it. Through this design, the connecting member 6 can respond quickly to the movement of the cam, ensuring the timeliness and accuracy of the clamping action. When the cam swings, the connecting member 6 is squeezed and pushed to swing. When the cam swings, the connecting member 6 is squeezed to make it produce corresponding movement. This movement mechanism improves the automation level of the equipment, reduces manual intervention, and improves cutting efficiency and safety.

[0034] The connecting member 6 is set to a horizontal L-shape when the cutting assembly 1 is not swinging, and a connecting seat 14 is hinged between the two cams. The base 3 is fixedly installed on the side of the connecting seat 14 close to the blade 15. The base 3 provides a stable base for the entire cutting assembly. The fixed connection of the base 3 ensures the stability and accuracy of the blade 15 during the cutting process, and prevents cutting deviations caused by the instability of the base 3. The middle part of the connecting member 6 is rotatably installed with the seventh connecting rod 4, allowing the connecting member 6 to rotate around the seventh connecting rod 4. This rotatable installation allows the connecting member 6 to move flexibly when the cutting assembly 1 swings, reduces friction and wear, extends the service life of the equipment, and improves the adaptability of the equipment, so that It can adapt to workpieces of different shapes and sizes. The two ends of the seventh connecting rod 4 are rotatably installed on the base 3, which ensures the stability of the blade 15 during the cutting process, thereby ensuring the processing accuracy and product consistency. When the cutting assembly 1 starts to swing toward the door and window workpiece, the connecting member 6 swings counterclockwise around the seventh connecting rod 4. This step causes the end of the connecting member 6 away from the connecting seat 14 to move upward to clamp the workpiece. This clamping action ensures the stability of the workpiece during the cutting process, prevents processing errors caused by the movement of the workpiece, and improves the safety and efficiency of the processing process. In this way, the equipment can achieve precise multi-angle cutting operations to meet complex processing requirements.

[0035] The clamping assembly 2 includes a second connecting rod 21, which is a key part of the equipment for fixing the door and window workpiece. The setting of the second connecting rod 21 enables the clamping assembly 2 to stably fix the workpiece. This design enhances the stability of the workpiece clamping and ensures the cutting accuracy. The eighth connecting rod 5 is rotatably installed between the lower ends of the two second connecting rods 21. Such a layout allows the eighth connecting rod 5 to flexibly rotate between the clamping assemblies 2. This rotation ability makes the equipment more efficient in clamping and releasing the workpiece, reduces the friction and wear caused by the fixed installation, thereby extending the service life of the equipment and improving the processing efficiency. The middle section of the eighth connecting rod 5 is hinged at the end of the connecting member 6 away from the blade 15, so that the eighth connecting rod 5 can move up and down under the push of the cam, thereby achieving the clamping and loosening of the workpiece. The hinged design provides better force transmission efficiency and ensures the clamping. The accuracy and reliability of the holding action are improved, and the equipment can also adapt to door and window workpieces of different thicknesses and widths. When the cam swings, the eighth connecting rod 5 is pushed upward through the connecting piece 6, and the swing of the cam is converted into the linear motion of the eighth connecting rod 5, thereby effectively transmitting the power to the clamping assembly 2. This design simplifies the force transmission path, improves the force utilization efficiency, and reduces energy loss. At the same time, it also makes the clamping action faster and more accurate, and improves the overall processing efficiency. The eighth connecting rod 5 pushes the two second connecting rods 21 to move upward to clamp the workpiece. This linkage mechanism ensures the stable fixation of the workpiece during the cutting process, and prevents processing errors caused by workpiece movement or vibration. By precisely controlling the movement of the second connecting rod 21, the equipment can better adapt to different processing conditions, improve the flexibility and adaptability of processing, and also enhance the safety of workpiece processing.

[0036] Both ends of the sixth connecting rod 27 away from the second connecting rod 21 are hinged with the fifth connecting rod 26, so that the fifth connecting rod 26 can swing under the push of the sixth connecting rod 27. This design allows the fifth connecting rod 26 to respond flexibly during operation, which helps to achieve precise positioning and clamping of the workpiece, while reducing mechanical interference, improving the flexibility and operating range of the equipment. The fifth connecting rod 26 is arranged below the base 3, and one end of the fifth connecting rod 26 away from the second connecting rod 21 is hinged with the fourth connecting rod 25, and the middle sections of the two fourth connecting rods 25 are hinged on the side walls of the base 3. This symmetrical layout provides a balanced force distribution, ensuring stability and uniformity when clamping the workpiece. This configuration of the fourth connecting rod 25 allows it to be in the fifth The connecting rod 26 swings under the push of the connecting rod, thereby clamping and releasing the workpiece, improving the efficiency and accuracy of the processing process. When the second connecting rod 21 moves upward, the sixth connecting rod 27 pushes the fifth connecting rod 26 to move away from the second connecting rod 21. This action further pushes the fourth connecting rod 25 to swing, so that the upper end of the fourth connecting rod 25 approaches the door and window workpiece. This linkage mechanism enables the equipment to accurately control the clamping force and position of the workpiece, optimizes the clamping stability during the cutting process, reduces the processing errors caused by workpiece movement or vibration, and improves the safety and efficiency of processing. At the same time, this design also enables the equipment to adapt to workpieces of different sizes and has good flexibility and adaptability.

[0037] A plurality of guide rings 8 are fixedly mounted on the surface of the base 3. The guide rings 8 provide structural stability and precision in operation. The fixed installation of the guide rings 8 enables the equipment to maintain rigidity and reduce vibration during the cutting process. At the same time, it also provides necessary guidance for other components, ensuring accurate alignment and smooth operation during the processing. The upper end of the fourth connecting rod 25 is hinged with a third connecting rod 23. The third connecting rod 23 can swing under the push of the fourth connecting rod 25, so that the third connecting rod 23 can respond flexibly during operation, which is helpful to achieve accurate positioning and clamping of the workpiece, while reducing mechanical interference, improving the flexibility and operating range of the equipment, and the guide ring 8 is set on the top of the third connecting rod 23, so that the third connecting rod 23 can swing when swinging. The internal movement of the guide ring 8 provides guidance for the third connecting rod 23 through the guide ring 8, ensuring precise alignment and smooth operation during the processing, while also reducing friction and wear during operation, improving the durability of the equipment and the convenience of maintenance. The fourth connecting rod 25 pushes the third connecting rod 23 to approach the door and window workpiece inside the guide ring 8. This action enables the equipment to accurately control the clamping force and position of the workpiece. This precise control optimizes the clamping stability during the cutting process, reduces processing errors caused by workpiece movement or vibration, and improves processing safety and efficiency. At the same time, this design also enables the equipment to adapt to workpieces of different sizes, with good flexibility and adaptability, ensuring high precision and high efficiency during the processing process.

[0038] The external sliding sleeve of the third connecting rod 23 is provided with an extrusion block 22, and the extrusion block 22 slides freely on the third connecting rod 23 to meet the fixing requirements of different door and window workpieces. The sliding sleeve provides a flexible adjustment mechanism, so that the equipment can be fine-tuned according to the specific size and cutting depth of the workpiece to ensure precise matching and stable clamping during the cutting process. A screw 24 is installed above the extrusion block 22, and the screw 24 squeezes the third connecting rod 23 downward to ensure that under the action of cutting pressure, the extrusion block 22 can firmly clamp the workpiece to prevent it from sliding or shifting during the cutting process. The clamping can be easily controlled by adjusting the screw 24. The force is to adapt to metal door and window materials of different hardness and thickness, ensure the stability during the processing and the processing quality of the workpiece, and fix the extrusion block 22 on the third connecting rod 23. This fixing method not only improves the clamping rigidity of the equipment, but also enhances the safety during the cutting process. By accurately controlling the tightness of the screw 24, damage to the workpiece or tool wear caused by improper clamping can be avoided. At the same time, the processing error caused by the movement of the workpiece is also reduced, and the processing accuracy and efficiency are improved. In addition, this design also simplifies the adjustment process of the equipment, allowing the operator to quickly replace the workpiece and set up the equipment, thereby improving the overall production efficiency.

[0039] Several guide seats 7 are fixedly installed under the base 3. As an important part of the equipment, the guide seats 7 provide structural stability and accuracy in operation. The fixed installation of the guide seats 7 enables the equipment to maintain rigidity and reduce vibration during the cutting process. At the same time, it also provides necessary support and guidance for other components, ensuring accurate alignment and smooth operation during the processing. The guide seat 7 is sleeved on the top of the second connecting rod 21. This structure provides a stable sliding path for the second connecting rod 21. By sleeved on the top of the second connecting rod 21, the equipment ensures that the movement of the connecting rod during the cutting process is more stable and accurate, thereby improving the cutting accuracy and the processing of door and window products. The sleeve structure also helps to reduce machine failures and material waste caused by improper movement of the connecting rod. A cross-shaped slot is provided at the downward end of the guide seat 7, allowing the pin 211 to slide freely up and down in the slot. The hinge point between the second connecting rod 21 and the two sixth connecting rods 27 is provided with a pin 211 that passes through the second connecting rod 21 and the two sixth connecting rods 27. The sliding ability of the pin 211 reduces friction during the cutting process, ensures smooth movement of the connecting rod, reduces wear, and extends the maintenance cycle and service life of the equipment. This design also improves the response speed of the equipment, so that the equipment can be quickly adjusted to a suitable cutting position when processing metal doors and windows of complex shapes.

[0040] When the present embodiment is used, the metal door and window are placed between the several extrusion blocks 22 on the base 3, and the handle 16 is pressed downward to make the blade 15 approach the door and window workpiece, and the motor inside the protective shell 12 drives the blade 15 to rotate, and the high-speed rotation of the motor drives the blade 15 to cut the metal door and window, thereby ensuring the continuity and uniformity of the cutting process; while the blade 15 cuts the door and window workpiece downward, it drives the cam to squeeze the top of the connecting member 6, so that the other end of the connecting member 6 swings upward, and then the two second connecting rods 21 are pushed upward through the eighth connecting rod 5, and the two hinged ends of the second connecting rods 21 are The sixth connecting rod 27 is pushed by the second connecting rod 21 to form a T-shape in a colinear manner with the second connecting rod 21, thereby pushing the two fifth connecting rods 26 in a direction away from the second connecting rod 21, and pushing the fourth connecting rod 25 to swing through the fifth connecting rod 26, so that the top end of the fourth connecting rod 25 swings toward the door and window workpiece, thereby performing multi-point fixation of the door and window workpiece through a plurality of extrusion blocks 22, reducing processing errors caused by workpiece movement or vibration, and improving processing safety and efficiency. At the same time, this design also enables the equipment to adapt to workpieces of different sizes, and has good flexibility and adaptability.
