Description

Modular door and window frame profile structure and manufacturing process Technical Field

[0001] This application relates to the field of building profiles, and in particular to a composite door and window frame profile structure. Background Technology

[0002] The frame materials for metal doors and windows are generally aluminum alloy, cold-rolled steel, and hot-rolled steel. Multiple profiles are spliced ​​and fixed into rectangular and irregular shapes for use on the exterior of buildings, thereby allowing sufficient natural light into the interior and creating a warm indoor environment in winter and a cool indoor environment in summer.

[0003] In related technologies, door and window frames include a frame body, which comprises multiple overlapping profile frames and a fixed frame, each profile frame being an independent profile. A thermal break strip is installed between every two adjacent profile frames. The profile frames are typically integrally formed by cold-pressing metal strips, and the connection between the thermal break strip and the profile frame is a snap-fit ​​connection; therefore, a groove structure for snapping the thermal break strip is also provided on it.

[0004] Based on the usage and assembly requirements of the profile frame, the one-time cold pressing process is quite difficult in terms of both mold design and material forming, which greatly increases the relevant manufacturing costs. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a combined door and window frame profile structure and manufacturing process.

[0006] The combined door and window frame structure provided in this application adopts the following technical solution.

[0007] A modular door and window frame profile structure includes a profile frame connected to a thermal break strip. The profile frame includes a main frame and a mating body. The mating body and the thermal break strip are snapped together, and the mating body is detachably connected to the main frame.

[0008] By adopting the above solution, the original complex integrated profile frame structure is decomposed, the processing difficulty of a single main frame and a single mating body is lower, and the operation of mating the thermal insulation strip and the mating body is more convenient than the operation of mating the thermal insulation strip and the profile frame, thus reducing the manufacturing and processing costs.

[0009] Preferably, the heat insulation strip is provided with a mating protrusion, and the mating body is provided with a mating groove, wherein the mating protrusion is embedded in the mating groove and abuts against the groove wall.

[0010] The interlocking connection between the mating body and the thermal insulation strip is achieved through the mutual cooperation of the protrusions and the grooves.

[0011] Preferably, the mating body has two mating wings, and the mating groove is formed between the two mating wings; before the mating protrusion enters the mating groove, the two mating wings are inclined in opposite directions with respect to the extension direction of the mating body, and after the mating protrusion enters the mating groove, the two mating wings are parallel with respect to the extension direction of the mating body.

[0012] By adopting the above scheme, during the connection of the heat insulation strip and the mating body, the mating flanges are flared, which facilitates the mating protrusion of the heat insulation strip to smoothly enter the space formed by the two mating flanges. Then, through the plastic deformation characteristics of the material itself, force is applied to the mating flanges so that the mating flanges abut and lock onto the mating protrusion, thus completing the connection between the heat insulation strip and the mating body.

[0013] Preferably, the main frame and the mating body are interlocked, the main frame has an installation groove, the mating body has an installation protrusion, the installation protrusion is embedded in the installation groove and abuts against the groove wall.

[0014] Preferably, the mating body has a structural chamfer, and after the mounting protrusion enters the mounting groove, a solder groove is formed between the mating body and the main frame through the structural chamfer.

[0015] By adopting the above solution, laser micro-welding reinforcement of the main frame and mating parts can be selectively performed according to the differences in the product's usage environment or functional requirements. The solder groove is used to store solder, thereby reducing the impact of the weld formation on the overall flatness of the profile frame.

[0016] Preferably, the mating body has blind holes, the opening of which is located on the side of the mating body away from the mating flange, and the bottom of which is located inside the mating flange. A reinforcing rod is inserted into the blind hole, and the hardness of the reinforcing rod is greater than that of the mating body and the mating flange. There are multiple blind holes arranged along the length direction of the mating body. The ends of the multiple reinforcing rods arranged in a direction away from the bottom of the blind holes are fixedly connected to the same connecting rod. The length direction of the connecting rod is consistent with the length direction of the mating body. A support rod groove is provided on the main frame, and the length direction of the support rod groove is consistent with the length direction of the main frame. The connecting rod is located in the support rod groove, and the connecting rod abuts against the groove wall.

[0017] By adopting the above scheme, when the connecting rod is inserted into the strut groove, due to the deformation of the mating flange relative to the mating body, the connecting rod generates a contact force against the groove wall of the strut groove. The direction of the contact force is towards the mounting groove. The connecting rod is subjected to a reaction force from the strut groove, which makes each reinforcing rod tend to swing towards the mating groove. The reinforcing rod thus has a reverse deformation force on the mating flange, thereby improving the clamping stability of the mating flange on the mating protrusion in the assembly state.

[0018] The manufacturing process for the aforementioned combined door and window frame structure provided in this application adopts the following technical solution.

[0019] A manufacturing process for the above-mentioned combined door and window frame structure includes the following steps in sequence:

[0020] S1: The main frame and the mating body are made separately. The mating body and the mating wing are integrally formed. In the natural state, the two mating wing on the mating body are inclined in opposite directions about the extension direction of the mating body.

[0021] S2: Place the mating protrusion of the heat insulation strip between the two mating flanges, and use the combination equipment to pressurize the two mating flanges so that the two mating flanges tightly clamp the mating protrusion;

[0022] S3: Use assembly equipment to connect the mating body and the main frame;

[0023] S4: Remove the assembled main frame, mating body, and thermal insulation strip from the assembly equipment.

[0024] Preferably, steps S2 and S3 are performed simultaneously on a combination device. The combination device includes a placement frame, a pusher frame, and a rolling mechanism. The rolling mechanism is located on the placement frame and includes multiple rolling wheels rotatably connected to the placement frame. The main frame is placed on the placement frame, and the axis of the rolling wheels is perpendicular to the length direction of the main frame. The pusher frame is slidable relative to the placement frame, and the sliding direction is consistent with the length direction of the main frame. When the pusher frame moves, it applies a thrust to the mating body and the heat insulation strip, causing the mating body and the heat insulation strip to move. During the movement of the mating body and the heat insulation strip, the mating flange and the wheel surface of the rolling wheel roll and abut against each other.

[0025] By adopting the above scheme, during the process of pushing the mating body and the heat insulation strip towards the placement frame, the rolling roller rolls against the mating flange, thereby generating pressure on the mating flange and causing it to undergo plastic deformation relative to the mating body, thus improving the clamping tightness of the mating flange on the heat insulation strip.

[0026] Preferably, the placement frame is equipped with a drive motor, which controls the rotation of one or more of the rolling rollers; the rolling mechanism further includes a material ejection assembly, which includes a movable frame with multiple material ejection rollers rotatably mounted on it. The movable frame is movably connected to the placement frame, and its movement direction is towards or away from the main frame. The material ejection rollers are multiple, and each material ejection roller corresponds to one rolling roller. A universal coupling connects the axle of the individual rolling roller and the axle of the material ejection roller. The material ejection assembly also includes a control source for controlling the movement of the movable frame.

[0027] By adopting the above scheme, during the movement of the mating body relative to the main frame, the ejector rollers do not contact the main frame. After the main frame and the mating body are docked, the movable frame approaches the main frame, causing each ejector roller to abut against the main frame. At this time, when the rolling roller rotates again, each ejector roller also rotates synchronously, generating a pushing friction force on the main frame, thereby moving it and achieving the purpose of removing the assembled main frame, mating body, and heat insulation strip from the placement frame together.

[0028] Preferably, step S4 further includes welding the main frame and the mating body, and the assembly equipment further includes a laser welding gun, which is fixed relative to the placement frame and located at one end of the placement frame near the push frame.

[0029] By adopting the above solution, based on the product manufacturing requirements, and taking advantage of the movement trend of the main frame and the mating body moving together during unloading, the laser welding gun is activated to weld the two together, thereby achieving weld reinforcement.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By dividing the profile frame into a main frame and mating parts, the original complex structure of the integrated profile frame is decomposed. The processing difficulty of a single main frame and a single mating part is lower. The operation of mating the thermal insulation strip with the mating part is more convenient than the operation of mating the thermal insulation strip with the profile frame, thus reducing the manufacturing and processing costs.

[0032] 2. By setting the mating flanges, during the connection of the heat insulation strip and the mating body, the mating flanges are flared, which makes it easy for the mating protrusion of the heat insulation strip to smoothly enter the space formed by the two mating flanges. Then, the plastic deformation characteristics of the material itself are used to apply force to the mating flanges so that the mating flanges abut and lock the mating protrusion, thus completing the connection between the heat insulation strip and the mating body.

[0033] 3. Through the combination of equipment, the clamping of the insulation strip by the mating flange of the mating body, the mating snap-fit ​​between the mating body and the main frame, and the welding connection between the main frame and the mating body are completed in sequence, which is convenient to operate and has high production efficiency.

[0043] The present application will be further described in detail below with reference to Figures 1-8.

[0044] Example 1:

[0045] This application discloses a combined door and window frame profile structure, as shown in Figure 1, including a profile frame 2. The profile frame 2 is a split type, comprising a main frame 21 and a mating body 22 that are detachably connected to each other, both of which are aluminum alloy profiles. The mating body 22 is used to indirectly connect the thermal insulation strip 1 and the profile frame 2.

[0046] As shown in Figures 1 and 2, taking a window as an example in this embodiment, both the door leaf and the door frame profile frame 2 include two overlapping main frames 21, with the thermal insulation strip 1 located between the two main frames 21. The connection between the thermal insulation strip 1 and the mating body 22, as well as the connection between the mating body 22 and the main frame 21, is a snap-fit ​​connection. The mating body 22 has two mating flanges 222 integrally formed on the same side, and the space formed between the two mating flanges 222 is a mating groove 221. The thermal insulation strip 1 has mating protrusions 11 integrally formed on both opposite sides. In its natural state, the cross-sectional shape of the mating protrusion 11 is consistent with the cross-sectional shape of the mating groove 221, and the mating groove 221 on a single mating body 22 allows one mating protrusion 11 to be inserted, thereby achieving the fixation of the mating body 22 and the thermal insulation strip 1.

[0047] As shown in Figure 2, during the assembly of the mating body 22 and the heat insulation strip 1, before the mating protrusion 11 enters the mating groove 221, the two mating flanges 222 are inclined in opposite directions with respect to the mating body 22, making the opening of the mating groove 221 flared, which facilitates the mating protrusion 11 to enter the mating groove 221 between the two mating flanges 222 more smoothly. After the mating protrusion 11 enters the mating groove 221, the mating flanges 222 are plastically bent by applying opposing pressure to them, so that the two mating flanges 222 abut against and clamp the opposite sides of the mating protrusion 11. At this time, the two mating flanges 222 are parallel with respect to the mating body 22, thereby completing the assembly of the mating body 22 and the heat insulation strip 1.

[0048] As shown in Figures 1 and 3, an integral mounting protrusion 223 is formed on the side of the mating body 22 opposite to the heat insulation strip 1. A mounting groove 211 is provided on the main frame 21 for the mounting protrusion 223 to be inserted. The mounting groove 211 is a dovetail groove, and the cross-section of the mounting protrusion 223 is also dovetail-shaped. The mounting protrusion 223 is inserted into the mounting groove 211, so that the mounting protrusion 223 and the groove wall of the mounting groove 211 fit tightly together, thereby causing the main frame 21 and the mating body 22 to abut and be relatively fixed. Structural chamfers 224 are formed at the corners on both sides of the mounting protrusion 223 on the mating body 22. After the mounting protrusion 223 enters the mounting groove 211, a solder groove 23 is formed between the mating body 22 and the main frame 21 through the structural chamfers 224. Depending on the product’s usage environment or functional requirements, laser micro-welding reinforcement can be selectively applied to the main frame 21 and the mating body 22. The solder groove 23 is used to store solder, thereby reducing the impact of the weld on the overall flatness of the profile frame 2 after the weld is formed.

[0049] Example 2:

[0050] As shown in Figures 4 and 5, based on Embodiment 1, the mating body 22 in this embodiment has multiple blind holes 225, with the bottom of each blind hole 225 located within a mating flange 222. Since there are two mating flanges 222, the blind holes 225 are arranged in two rows, with each row corresponding to one of the mating flanges 222 of the mating body 22. The arrangement direction of each row of blind holes 225 is consistent with the length direction of the mating body 22. A reinforcing rod 3 is inserted into each blind hole 225. The reinforcing rod 3 is made of stainless steel, and its hardness is greater than that of the mating body 22 and the mating flange 222. Each reinforcing rod 3 inserted into a single row of blind holes 225 is fixedly connected to the same connecting rod 31 at the end furthest from the bottom of the blind hole 225. The connecting rod 31 is made of the same material as the reinforcing rod 3. When the reinforcing rod 3 is inserted into the blind hole 225, the length direction of the connecting rod 31 is consistent with the length direction of the mating body 22.

[0051] As shown in Figures 4 and 5, the length direction of the connecting rod 31 is consistent with the length direction of the mating body 22. Two support rod slots 212 are provided on the main frame 21, with their length directions consistent with the main frame 21, and the two slots 212 are located on opposite sides of the mounting groove 211. Each support rod slot 212 accommodates one connecting rod 31. When the connecting rod 31 is inserted into the support rod slot 212, due to the deformable force of the mating flange 222 relative to the mating body 22, the connecting rod 31 generates a contact force against the groove wall of the support rod slot 212. The direction of this contact force is towards the mounting groove 211. The connecting rod 31 thus experiences a reaction force from the support rod slot 212, causing each reinforcing rod 3 to tend to swing towards the mating groove 221. Therefore, the reinforcing rod 3 exerts a reverse deformation force on the mating flange 222, thereby improving the clamping stability of the mating flange 222 on the mating protrusion 11 in the assembled state.

[0052] This application discloses a manufacturing process for the above-mentioned combined door and window frame profile structure, as shown in Figure 6, which includes the following steps in sequence:

[0053] S1: Component preparation, respectively fabricating the main frame 21 and the mating body 22, the mating body 22 and the mating wing 222 are integrally formed, in the natural state, the two mating wing 222 on the mating body 22 are inclined in opposite directions about the extension direction of the mating body 22;

[0054] S2: Combine the mating body 22 and the heat insulation strip 1, place the mating protrusion 11 of the heat insulation strip 1 between the two mating wings 222, and use the combination equipment to press the two mating wings 222 so that the two mating wings 222 tightly clamp the mating protrusion 11.

[0055] S3: Combine the mating body 22 and the main frame 21, and connect the mating body 22 and the main frame 21 using a combination device;

[0056] S4: Unloading. Remove the assembled main frame 21, mating body 22 and heat insulation strip 1 from the assembly equipment. During this process, the main frame 21 and mating body 22 can be selectively welded and reinforced according to product requirements.

[0057] As shown in Figure 7, S2 and S3 are performed simultaneously using a combined device. The combined device includes a placement frame 4 and a pusher frame 41. The pusher frame 41 is located on one side of the placement frame 4 and is movable relative to the placement frame 4 in a horizontal direction. The main frame 21 is placed on the placement frame 4, with the length direction of the main frame 21 aligned with the moving direction of the pusher frame 41. The pusher frame 41 is used to place the mating body 22 and the heat insulation strip 1, and to carry the mating body 22 and the heat insulation strip 1 closer to the placement frame 4. The placement frame 4 is equipped with a power mechanism (not shown in the figure) for controlling the movement of the pusher frame 41. The power mechanism can be any mechanical structure capable of bidirectional linear motion, such as a cylinder, hydraulic cylinder, or rack and pinion.

[0058] As shown in Figures 7 and 8, the length direction of the mating body 22 placed on the pusher frame 41 is consistent with the moving direction of the pusher frame 41. The pusher frame 41 moves closer to the placement frame 4, causing the mating body 22 to move next to the main frame 21, so that the mounting protrusion 223 of the mating body 22 is inserted into the mounting groove 211 of the main frame 21. Since the raw material lengths of the main frame 21 and the mating body 22 are relatively long, the combined equipment also includes a rolling mechanism 5 to reduce the pushing stroke requirement of the pusher frame 41. The rolling mechanism 5 includes a drive motor 52 and multiple rolling wheels 51. The rolling wheels 51 are rotatably connected to the placement frame 4, with some rolling wheels 51 located above the mating body 22 and some rolling wheels 51 located below the mating body 22. For a single mating body 22, there are two sets of rolling wheels 51. Each set of rolling wheels 51 is oriented along the moving direction of the pusher frame 41, and the axis of each rolling wheel 51 is perpendicular to the length direction of the main frame 21. When the mating body 22 enters the placement frame 4, the two sets of rolling rollers 51 respectively abut against the two mating flanges 222 on the side opposite to the mating protrusion 11. The wheel surface of the rolling rollers 51 rolls and abuts against the mating flanges 222, applying a thrust to them, causing the mating flanges 222 to undergo plastic deformation, so as to tightly abut against the mating protrusion 11. The drive motor 52 is fixedly installed on the placement frame 4 near the push frame 41. The output shaft of the drive motor 52 is coaxially connected to one of the rolling rollers 51 closest to the push frame 41 to control its rotation. Once the rolling roller 51 connected to the drive motor 52 contacts the mating flange 222, the mating body 22 and the heat insulation strip 1 receive power from the drive motor 52, and the push frame 41 can stop moving.

[0059] As shown in Figures 7 and 8, the rolling mechanism 5 also includes an ejector assembly 6. Driven by the rolling roller 51, when the mating body 22 and the main frame 21 are aligned, the main frame 21 and the mating body 22 are snapped together. The ejector assembly 6 is used to remove the assembled main frame 21, mating body 22, and heat insulation strip 1 from the placement frame 4 together. The ejector assembly 6 includes a movable frame 61, which is movably connected to the placement frame 4, and its movement direction is towards or away from the main frame 21. Multiple ejector rollers 62 are rotatably arranged on the movable frame 61, with each ejector roller 62 corresponding to one rolling roller 51. Except for the rolling roller 51 connected to the drive motor 52, a universal coupling 63 is connected between the axle of each rolling roller 51 and the axle of the ejector roller 62, that is, the rolling roller 51 and the ejector roller 62 rotate synchronously at the same speed.

[0060] As shown in Figures 7 and 8, this embodiment is illustrated by taking the example of the side wall surface of the main frame 21 being flush with the side wall surface of the mating body 22. The movable frame 61 is hinged relative to the placement frame 4, and the hinge axis coincides with the rotation axis of the universal coupling 63 relative to the axle of the rolling wheel 51. A control source 64 for controlling the rotation of the movable frame is provided below the placement frame 4. In this embodiment, the control source 64 is a cylinder, the cylinder body of which is hinged to the placement frame 4, and the piston rod end is hinged to the movable frame 61. When the piston rod of the cylinder extends, the movable frame 61 swings towards the main frame 21. During the movement of the mating body 22 relative to the main frame 21, the ejector wheels 62 do not contact the main frame 21. After the main frame 21 and the mating body 22 are docked, the movable frame 61 moves closer to the main frame 21, causing each ejector wheel 62 to abut against the main frame 21. At this time, when the rolling roller 51 rotates again, each unloading roller 62 also rotates synchronously, generating a pushing friction force on the main frame 21, thereby moving it and achieving the purpose of unloading the assembled main frame 21, mating body 22 and heat insulation strip 1 together from the placement rack 4.

[0061] As shown in Figure 7, the combined equipment also includes a laser welding gun 42, which is fixed relative to the placement frame 4 and located at one end of the placement frame 4 near the pusher frame 41. During the unloading process, the laser welding gun 42 can be activated as needed to weld and reinforce the main frame 21 and the mating body 22.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
