Description

Technical Field

[0001] The utility model belongs to the technical field related to door and window corner assembly processing, and specifically relates to a door and window numerical control corner assembly equipment. Background Art

[0002] The existing door and window corner assembly equipment uses technology from the 1990s, which has always troubled door and window manufacturers and has been unable to ensure the requirements of seamless splicing in mass production. With the rise of high-rise and high-end residential buildings in my country in the 21st century, real estate companies have continuously put forward strict requirements on doors and windows such as thermal insulation, heat preservation, and air tightness. The existing corner assembly machines can no longer meet the current door and window corner assembly process requirements.

[0003] The structural principle of the existing corner assembly machine is to use a hydraulic cylinder to push the mechanical structure to realize the movement of the corner assembly knife at a fixed angle. This fixed angle and the door and window profiles generate a thrust during the corner assembly process. The greater the hydraulic pressure and the faster the speed during the corner assembly process, the greater the backward thrust acting on the door and window profiles. This thrust will cause gaps and dislocations at the joints of the door and window profiles. See attached Figure 7 .

[0004] In addition, the existing corner assembly machine structure controls whether the corner is in place by controlling the movement distance of the corner assembly knife during the corner assembly process. When using the corner assembly machine, it is not easy for door and window manufacturers to grasp the size of the corner assembly distance. The corner assembly knife generates thrust on the new door and window materials, and the doors and windows will move backwards due to the thrust. If the movement distance of the corner assembly knife is large, it is easy to cause the door and window profiles to be squeezed and deformed seriously. If the movement distance of the corner assembly knife is small, it is easy to cause the door and window profiles to be squeezed out of place. Therefore, the debugging process of the existing corner assembly machine is difficult and requires high debugging technology. The debugging process requires continuous processing and verification, which takes a long time. In addition, the defective products generated during the verification process will also increase the production cost.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0032] The two ends of the X-axis lead screw 20 are respectively connected to the X-axis left slide 16 and the X-axis right slide 11 through a nut fixing seat 25. The bottom surfaces of the X-axis left slide 16 and the X-axis right slide 11 are provided with movable sliders 19 near the two side edges.

[0035] The working principle of the utility model is:

[0036] The working process of the device:

[0037] 1. Install the angle bracket into the cavity of the door and window profile 6;

[0038] 2. Place the door and window profile 6 on the workbench 5 at an angle of 90°, with the outer surface of the door and window profile 6 close to the positioning strip 31 on the workbench 5;

[0039] 3. Start the pressing assembly 4, connect the gas to the pressing cylinder 30, and the pressing cylinder 30 extends to press the door and window profile 6;

[0040] 4. The Y-axis assembly 3 is driven by the Y-axis servo motor 26 to push the Y-axis slide forward. When it moves to the distance set by the PLC, the Y-axis slide stops moving;

[0041] 5. The X-axis slide assembly 2 starts to move, and the X-axis servo motor 7 rotates to amplify the torque several times through the reducer 8, and drives the left and right corner cutter 13 assemblies to move toward each other through the coupling 10. At this time, when the PLC program controls the corner cutter 13 to move to the contact position of the door and window profile 6, it is converted into the torque mode to realize the corner cutter movement. When the corner cutter 13 is subjected to the resistance of the door and window profile 6 after deformation and reaches the torque set by the PLC, the X-axis servo motor 7 starts to reverse, and the corner cutter 13 returns to the specified position;

[0042] 6. The Y-axis servo motor 26 reverses and returns to the specified position;

[0043] 7. Complete a corner grouping process;

[0044] The working principle of the X-axis sliding assembly is as follows: after receiving the signal, the X-axis servo motor 7 drives the reducer 8 to move, and after amplifying the torque several times, the torque is transmitted to the left and right spiral X-axis screws 20 through the coupling 10. The X-axis screw 20 transmits the torque to the nut fixing seat 25 through rotational movement. The nut fixing seat 25 is fixed on the X-axis left slide 16 and the X-axis right slide 11. The left and right spiral screws move simultaneously, driving the X-axis left slide 16 and the X-axis right slide 11 to move toward each other, so as to achieve the purpose of the left and right side cornering knives 13 extruding the profile; the X-axis sliding assembly is the main mechanism component for achieving the angle combination, and the servo driver is controlled by the PLC to generate an electrical signal, driving the servo motor to rotate, increasing the torque through the reducer 8, and transmitting the torque to the cornering knife 13, so as to achieve the angle combination of the door and window profile 6;

[0045] The working principle of the Y-axis assembly 3 is as follows: the Y-axis servo motor 26 is connected to the Y-axis screw rod 23 through the coupling 10, transmitting the rotational force to push the Y-axis slide to move forward and backward, so as to realize the forward and backward movement and positioning of the cornering knife 13; the Y-axis assembly 3 controls the servo driver through the PLC to generate an electrical signal, drives the servo motor to rotate, and drives the Y-axis slide to move forward and backward;

[0046] The working principle of the clamping assembly 4 is as follows: a positioning device with a 90° angle composed of a positioning strip 31 is fixed on the workbench 5, the door and window profile 6 is fixed on the workbench 5 at a 90° angle, and a clamping cylinder 30 is used to clamp the profile; the cylinder fixing plate 29 that fixes the clamping cylinder can move up and down under the action of the lifting screw rod 33 and the lifting nut 32. If the height of the door and window profile 6 changes, the lifting screw rod 33 can be shaken to drive the cylinder fixing plate 29 to move, so as to achieve the purpose of the cylinder clamping the profile; the lifting screw rod 33 is driven to rotate by the hand-cranked wheel, and the lifting screw rod 33 cooperates with the lifting nut 32 fixed on the cylinder fixing seat, and the two ends of the cylinder fixing plate 29 are fixed on the slide block, and move up and down along the lifting guide rail 27 to control the height of the clamping cylinder 30 and the door and window profile 6 to clamp the profile; the profile is 90° guaranteed by the positioning strip 31 fixed on the workbench 5. After the cylinder is clamped, the profile can be guaranteed not to be subjected to force and move during the entire angle grouping process, so as to ensure the stability of the entire angle grouping;

[0047] The equipment of the utility model can realize the characteristic of synchronous opposite movement of two moving bodies mainly through the forward and reverse spiral direction screws during rotation. The servo motor amplifies the torque through the reducer 8 and transmits it to the screw for rotation, so as to realize precise control of the position and torque of the opposite movement. The movement direction of the cornering knife 13 is horizontal to the force direction of the cornering process of the door and window profile 6, and the force is reasonable. The door and window cornering extrusion process is controlled by the computer through the precise control of the servo motor torque to control the entire cornering process. When the cornering knife 13 is subjected to the profile extrusion deformation resistance and reaches the rated torque set by the computer, the cornering knife 13 automatically retreats to ensure that the extrusion force on each product is consistent, and the consistency of the cornering quality of batch production of doors and windows is ensured.

Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model.
