A pressure-self-regulating fireproof door panel processing equipment

Abstract

This invention relates to the field of fire door processing technology, and particularly to a pressure-self-adjusting fire door panel processing equipment. It includes a processing platform with a supporting turntable at its top center; the top of the supporting turntable is equipped with a supporting frame. When processing fire door panels, the door frame and door panel can remain relatively fixed in the vertical direction. This allows the self-adjusting processing mechanism to compare the differences between the door panel edge and the inner wall of the door frame in real time and adjust the processing pressure accordingly. Simultaneously, when the self-adjusting processing mechanism moves to a corner of the door panel, a corresponding distance sensor detects this and, after releasing the corresponding limiting pressure block from the door panel, controls the connecting block to rotate, exposing the corner edge of the door panel for processing. This improves the processing quality of the equipment while avoiding processing blind spots.

Description

[0001] This application is a divisional application of application filed on November 26, 2024, with application number 2024117027861 and invention title "A pressure self-adjusting fireproof door panel processing equipment and method thereof". Technical Field

[0002] This invention belongs to the field of fire door processing technology, and specifically relates to a pressure self-adjusting type fire door panel processing equipment. Background Technology

[0003] During the manufacturing process of fire doors, the door panel and the door frame are processed separately. The door frame needs to be cut into pieces according to the required size, specifications, and model of the fire door, while the door panel is integrally formed according to the size of the door frame, and then the edges are trimmed to ensure a tight fit with the door frame.

[0004] A search revealed that Chinese Patent Publication No. CN113231763A, published on August 10, 2021, discloses a steel fire door forming and processing machine and method, including a base plate, a support mechanism, and an alignment adjustment mechanism. The support mechanism is located in the middle of the upper surface of the base plate, and the alignment adjustment mechanism is located above the support mechanism. The alignment adjustment mechanism is installed on the base plate via a sliding fit. This invention solves the problems of existing steel fire door forming and processing machines being unable to stably clamp and lock different types of door frames, having a limited scope of application, poor applicability, and poor stability of the door frame during pre-welding assembly, leading to easy shaking and affecting the assembly accuracy. It also solves the problems of the inability to quickly and accurately align and splice the horizontal and vertical door frames before welding, resulting in excessive gaps during welding, affecting welding accuracy and quality, low compatibility between the door frame and door panel, and poor fire resistance.

[0020] The four sets of sensor fixing mechanisms are used to splice and fix the edge strips of the fire door frame;

[0021] The control welding module welds the joints of the door frame;

[0022] The four sets of sensor fixing mechanisms are used to fix the fire door panel directly below the door frame;

[0025] The four edges of the fire door panel are processed sequentially.

[0026] Complete the processing of fireproof door panels.

[0027] The beneficial effects of this invention are:

[0028] 1. The sensing and fixing mechanism includes a support shaft with four sets of connecting blocks in the vertical direction. Each set of connecting blocks has two sets of annular limiting plates at the end away from the support shaft. This allows the door frame and door panel to remain relatively fixed in the vertical direction during the processing of the fire door. This facilitates the self-adjusting processing mechanism to compare the differences with the inner wall of the door frame in real time and adjust the processing pressure when processing the edge of the door panel. At the same time, when the self-adjusting processing mechanism moves to the corner of the door panel, the corresponding distance sensor will detect it and control the connecting block to rotate after releasing the contact between the corresponding limiting pressure block and the door panel, so that the corner edge of the door panel is exposed for processing. This improves the processing quality of the processing equipment and avoids processing blind spots.

[0029] 2. By using a scanning camera to scan the inner wall of the fire door frame in real time and controlling four sets of second electric push rods to adjust the processing pressure of the processing components in real time, the edge of the door panel can be more closely matched with the inner wall of the door frame. At the same time, by individually controlling the four sets of second electric push rods, the processing motor and processing components can be kept in an inclined state, so that the cutting teeth on the inclined processing ring are kept horizontal with the edge of the door panel. This allows the processing equipment to cut the protruding parts of the edge of the door panel, improving the processing effect of the processing equipment.

[0030] 3. When the two sets of first limiting plates enter the two sets of first limiting grooves, they will squeeze the two sets of transmission plates, causing the two sets of transmission plates to drive the two sets of sealing plates to separate. This allows the collection groove to connect with the negative pressure collection chamber through the collection hole. At the same time, the two sets of telescopic baffles on the protective shell can fit against the top and bottom of the door panel, preventing metal debris from splashing in the processing area and allowing it to be sucked into the negative pressure collection chamber. This improves the debris collection effect of the processing equipment while enhancing the working safety of the processing equipment.

[0031] 4. By controlling the two sets of second limiting plates to disengage from the second limiting groove while simultaneously driving the two sets of first limiting plates into the first limiting groove, the processing motor and processing components can follow the moving support mechanism to process the edge of the door panel. At the same time, when maintenance of the processing structure is required, the first limiting plate can be directly controlled to disengage from the first limiting groove to directly disassemble the processing structure, which improves the ease of use of the processing equipment and the maintenance efficiency.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] This invention provides a pressure-self-adjusting fireproof door panel processing device, including a processing platform 1. For example, as shown... Figure 1 and Figure 2 As shown, a support turntable 2 is provided at the top center of the processing platform 1; a support frame 3 is provided at the top of the support turntable 2; a set of sensing and fixing mechanisms 4 are provided at the top corners of the support frame 3; a set of moving guide rails 5 are provided at the four sides of the top of the support frame 3; and a set of moving support mechanisms 6 is provided in each set of moving guide rails 5.

[0046] Specifically, a rotary telescopic module 7 is provided at one edge of the top of the processing platform 1; a self-adjusting processing mechanism 8 is driven to the output end of the rotary telescopic module 7; a mounting base 9 is provided at one edge of the top of the processing platform 1; a robotic arm 10 is provided on the top of the mounting base 9; a welding module 11 is driven to the output end of the robotic arm 10; four sets of dust collection holes 12 are arranged in a circular array on the top of the support turntable 2; each set of dust collection holes 12 is connected to a corresponding set of movable support mechanisms 6.

[0047] Specifically, the supporting turntable 2 is provided with a negative pressure collection chamber 13; the negative pressure collection chamber 13 has a ring-shaped cross-section when viewed from above and is connected to four sets of dust collection holes 12; a dust collection chamber 14 is provided on one side wall of the bottom of the negative pressure collection chamber 13; several sets of separating cleaning plates 15 are arranged in a ring array at the bottom of the supporting turntable 2; the two side walls of each set of separating cleaning plates 15 are respectively movably attached to the corresponding inner wall of the negative pressure collection chamber 13.

[0048] When processing the fireproof door panel, the four sets of door frame edge strips are first connected and fixed in the four sets of induction fixing mechanisms 4. Then, the support turntable 2 is controlled to drive the spliced ​​door frame to rotate, and the robotic arm 10 is controlled to drive the welding module 11 to weld the spliced ​​parts of the door frame in sequence. Then, the door panel is fixed directly below the door frame. Then, the self-adjusting processing mechanism 8 is controlled to connect with the corresponding moving support mechanism 6. Then, the moving support mechanism 6 drives the self-adjusting processing mechanism 8 to process the edge of the door panel. During the processing, the processing pressure is adjusted by comparing with the inner wall of the door frame in real time to ensure that the gap between the door panel and the door frame remains uniform after processing, thereby improving the use effect of the processing equipment. At the same time, during the processing of the door panel, the debris generated during processing will be sucked into the negative pressure collection chamber 13 under the negative pressure action of the negative pressure collection chamber 13, and transferred to the dust collection chamber 14 by several sets of separating cleaning plates 15 during the processing.

[0049] For example, Figure 3 and Figure 4 As shown, the sensing and fixing mechanism 4 includes a support block 401; a support shaft 402 is provided at the top center of the support block 401; four sets of connecting blocks 403 are movably sleeved on the outer wall of the support shaft 402; two sets of limiting plates 404 are symmetrically provided at the top and bottom of the side wall away from the support shaft 402 of each set of connecting blocks 403; the top view cross section of each set of limiting plates 404 is a fan-shaped ring; several sets of first electric push rods 406 are provided at equal intervals on the side wall away from the corresponding set of limiting plates 404 of each set of limiting plates 404.

[0050] Specifically, the output end of each set of first electric push rods 406 extends between the corresponding two sets of limiting plates 404 and is connected to a set of limiting pressure blocks 407; each set of limiting plates 404 is provided with a set of distance sensors 405 at the end away from the support shaft 402; each set of connecting blocks 403 is provided with a set of rotating cavities 408; each set of rotating cavities 408 is provided with a set of second gears 410; four sets of first gears 409 are sleeved on the outer wall of the support shaft 402; each set of first gears 409 is located in a corresponding set of rotating cavities 408 and is meshed with a corresponding set of second gears 410.

[0051] When processing the fire door panel, the two ends of the four sets of door frame edge strips of the fire door are respectively placed between the two sets of limiting plates 404. Then, the corresponding sets of first electric push rods 406 are controlled to drive the limiting pressure block 407 to clamp the top and bottom of the door frame edge strip, so that the splicing of the four sets of door frame edge strips is placed between the corresponding sets of leaf ring limiting plates 404, which facilitates the welding work. After the door frame is welded, the door leaf panel is fixed between the corresponding sets of limiting plates 404, so that the door leaf panel is located directly below the door frame. Then, the moving support mechanism 6 is controlled to drive the self-adjusting processing mechanism 8 to perform edge processing work on the door leaf panel.

[0052] When the self-adjusting processing mechanism 8 moves to the corner of the door panel, the corresponding distance sensor 405 will sense it and control several sets of first electric push rods 406 on the two sets of limit plates 404 to drive the limit pressure block 407 to release its contact with the door panel. Then, the corresponding second gear 410 is controlled to rotate, driving the connecting block 403 to rotate, so that the corner of the door panel is exposed for processing. At the same time, the other two sets of limit plates 404 fix and support the corner of the door panel, ensuring processing stability while avoiding processing blind spots and improving the processing quality of the processing equipment.

[0053] For example, Figure 5 and Figure 6 As shown, the movable support mechanism 6 includes a movable support base 601; a collection groove 602 is provided on the top of the movable support base 601; a collection hole 603 is provided on one inner wall of the collection groove 602; a collection pipe 604 is connected to one end of the collection hole 603 away from the collection groove 602; a collection pipe 604 is connected to one end of the collection pipe 604 away from the movable support base 601 and a corresponding set of dust collection holes 12; two sets of sealing plates 605 are symmetrically and movably inserted through the inner walls on both sides of the collection hole 603.

[0054] Specifically, two sets of first limiting grooves 606 are symmetrically provided on the inner walls of both sides of the collection groove 602; a set of transmission plates 607 are slidably connected in each set of first limiting grooves 606; several sets of compression springs 608 are symmetrically and equally spaced on the opposite side walls of the two sets of transmission plates 607; the end of each set of compression springs 608 away from the transmission plate 607 is connected to the inner wall of the corresponding set of first limiting grooves 606; each set of transmission plates 607 is connected to a corresponding set of sealing plates 605.

[0055] For example, Figure 7 As shown, the self-adjusting processing mechanism 8 includes a connecting plate 801; the connecting plate 801 is connected to the output end of the rotary telescopic module 7; a connecting groove 802 is provided on the side wall of the connecting plate 801 away from the rotary telescopic module 7; two sets of second limiting grooves 803 are symmetrically provided on the inner walls of both sides of the connecting groove 802; a connecting component 804 is provided on the side wall of the connecting plate 801 away from the rotary telescopic module 7.

[0056] Specifically, a processing motor 805 is provided at the end of the connecting component 804 away from the connecting plate 801; a processing component 806 is connected to the output end of the processing motor 805; a protective shell 807 is provided on the side wall of the connecting component 804 away from the connecting plate 801; the bottom of the protective shell 807 has an open structure; a processing through groove 808 is provided on the side wall of the protective shell 807 away from the connecting component 804; two sets of telescopic baffles 809 are symmetrically provided on the top and bottom inner walls of the processing through groove 808; a scanning camera 810 is provided on the top of the protective shell 807.

[0057] For example, Figure 8 As shown, the connecting assembly 804 includes a housing 80401; two sets of first limiting plates 80402 are symmetrically arranged on the side wall of the housing 80401 near the movable support mechanism 6; each set of first limiting plates 80402 is movably inserted into a corresponding set of first limiting grooves 606; two sets of second limiting plates 80403 are symmetrically arranged on the side wall of the housing 80401 near the connecting plate 801; each set of second limiting plates 80403 is movably inserted into a corresponding set of second limiting grooves 803; an adjustment groove 80407 is provided on the side wall of the housing 80401 near the protective shell 807;

[0058] Specifically, four sets of second electric push rods 80408 are arranged in a rectangular array on the inner wall of the adjusting groove 80407 away from the protective shell 807; each set of second electric push rods 80408 has a set of universal ball joints 80409 connected to its output end; the end of each set of universal ball joints 80409 away from the second electric push rod 80408 is hinged to the processing motor 805; the shell 80401 has an adjusting cavity 80404; the adjusting cavity 80404 has four sets of lead screws 80405; the four sets of lead screws 80405 are connected in sequence, and their two ends are rotatably connected to the corresponding inner wall of the adjusting cavity 80404; the central axes of the four sets of lead screws 80405 are on the same straight line; the thread directions of adjacent sets of lead screws 80405 are opposite.

[0059] Specifically, four sets of sliding plates 80406 are slidably connected to the bottom inner wall of the adjustment cavity 80404; each set of sliding plates 80406 is threadedly connected to a corresponding set of lead screws 80405; each set of first limiting plates 80402 is drivenly connected to a corresponding set of sliding plates 80406; and each set of second limiting plates 80403 is drivenly connected to a corresponding set of sliding plates 80406.

[0060] For example, Figure 9 As shown, the processing component 806 includes a grinding disc 80601; a processing ring 80602 is sleeved on the outer wall of the grinding disc 80601; the processing ring 80602 is inclined and has a number of cutting teeth 80603 arranged in a ring array on its outer wall.

[0061] During the processing of fireproof door panels, the rotating telescopic module 7 drives the self-adjusting processing mechanism 8 to the top of the moving support mechanism 6, and then controls the rotation of four sets of lead screws 80405. Under the threaded connection between the four sets of lead screws 80405 and the four sets of sliding plates 80406, the four sets of sliding plates 80406 move relative to each other in pairs. This causes the two sets of second limiting plates 80403 to disengage from the second limiting groove 803, while simultaneously causing the two sets of first limiting plates 80402 to enter the first limiting groove 606. This allows the processing motor 805 and the processing component 806 to follow the moving support mechanism 6 to process the edge of the door panel. At the same time, when maintenance of the processing structure is required, the first limiting plate 80402 can be directly controlled to disengage from the first limiting groove 606 to directly disassemble the processing structure. This improves both the ease of use of the processing equipment and the efficiency of maintenance.

[0062] During the processing of fireproof door panels, two sets of first limiting plates 80402 enter two sets of first limiting grooves 606, which squeeze two sets of transmission plates 607. This causes the two sets of transmission plates 607 to drive the two sets of sealing plates 605 to separate, thereby allowing the collection groove 602 to connect with the negative pressure collection chamber 13 through the collection hole 603. At the same time, the two sets of telescopic baffles 809 on the protective shell 807 can fit against the top and bottom of the door panel, preventing metal debris from splashing in the processing area and allowing it to be sucked into the negative pressure collection chamber 13. Then, several sets of separating cleaning plates 15 push it into the dust collection chamber 14 for collection during the processing. When the processing equipment is idle, the two sets of first limiting plates 80402 disengage from the first limiting grooves 606, and the two sets of transmission plates 607 reset and close the collection hole 603, preventing dust from entering the negative pressure collection chamber 13. This improves both the debris collection effect and the working safety of the processing equipment.

[0063] During the processing of fireproof door panels, the scanning camera 810 can scan the edge of the inner wall of the door frame in real time and adjust the processing pressure of the processing component 806 in real time by controlling the four sets of second electric push rods 80408, so that the edge of the door panel can better match the inner wall of the door frame. At the same time, by individually controlling the four sets of second electric push rods 80408, the processing motor 805 and the processing component 806 can be kept in an inclined state, so that the cutting teeth 80603 on the inclined processing ring 80602 are kept horizontal with the edge of the door panel, thereby enabling the processing equipment to cut the protruding part of the edge of the door panel, which improves both the processing quality and the processing effect of the processing equipment.

[0064] The sensing and fixing mechanism 4 includes a support shaft 402. The support shaft 402 has four sets of connecting blocks 403 in the vertical direction. Each set of connecting blocks 403 has two sets of fan-shaped limiting plates 404 at the end away from the support shaft 402. This allows the door frame and door panel to remain relatively fixed in the vertical direction during the processing of the fire door. This facilitates the self-adjusting processing mechanism 8 to compare the differences with the inner wall of the door frame in real time and adjust the processing pressure when processing the edge of the door panel. At the same time, when the self-adjusting processing mechanism 8 moves to the corner of the door panel, the corresponding distance sensor 405 will sense it and control the connecting block 403 to rotate after releasing the contact between the corresponding limiting pressure block 407 and the door panel. This exposes the corner of the door panel edge for processing, improving the processing quality of the processing equipment while avoiding processing blind spots.

[0065] By using a scanning camera 810 to scan the inner wall of the fire door frame in real time, and by controlling four sets of second electric push rods 80408 to adjust the processing pressure of the processing component 806 in real time, the edge of the door panel can be made to fit more closely with the inner wall of the door frame. At the same time, by individually controlling the four sets of second electric push rods 80408, the processing motor 805 and the processing component 806 can be kept in an inclined state, so that the cutting teeth 80603 on the inclined processing ring 80602 are kept horizontal with the edge of the door panel, thereby enabling the processing equipment to cut the protruding parts of the edge of the door panel and improving the processing effect of the processing equipment.

[0066] Four sets of induction fixing mechanisms 4 splice, fix, and weld the fire door frame. Then, the door panel is fixed to the bottom of the door frame through the four sets of induction fixing mechanisms 4. Subsequently, the movable support 601 is controlled to drive the processing component 806 to process the edge of the door panel. At the same time, the processing pressure of the processing component 806 is adjusted in real time by detecting the inner wall of the door frame, so that the edge of the door panel can better match the inner wall of the door frame. Furthermore, by controlling the processing component 806 to maintain an inclined state, the cutting teeth 80603 on the inclined processing ring 80602 are kept horizontal with the edge of the door panel, thereby cutting the protruding part of the edge of the door panel. This improves both the processing quality and the processing effect of the processing equipment.

[0067] The door panel is fixed between several sets of corresponding limiting plates 404, so that the door panel is located directly below the door frame. Then, the moving support mechanism 6 is controlled to drive the self-adjusting processing mechanism 8 to perform edge processing of the door panel. When the self-adjusting processing mechanism 8 moves to the corner of the door panel, the corresponding distance sensor 405 will sense it and control several sets of first electric push rods 406 on the two sets of limiting plates 404 to drive the limiting pressure block 407 to release contact with the door panel. Then, the corresponding second gear 410 is controlled to rotate, driving the connecting block 403 to rotate, so that the edge corner of the door panel is exposed for processing, avoiding processing blind spots.

[0068] When the two sets of first limiting plates 80402 enter the two sets of first limiting grooves 606, they will squeeze the two sets of transmission plates 607, causing the two sets of transmission plates 607 to drive the two sets of sealing plates 605 to separate. This allows the collection groove 602 to connect with the negative pressure collection chamber 13 through the collection hole 603. At the same time, the two sets of telescopic baffles 809 on the protective shell 807 can fit against the top and bottom of the door panel, so that metal chips in the processing area will not splash and can be sucked into the negative pressure collection chamber 13. This improves the chip collection effect of the processing equipment and enhances the working safety of the processing equipment.

[0069] By controlling the two sets of second limiting plates 80403 to disengage from the second limiting groove 803, while simultaneously driving the two sets of first limiting plates 80402 into the first limiting groove 606, the processing motor 805 and processing component 806 can follow the moving support mechanism 6 to process the edge of the door panel. At the same time, when maintenance of the processing structure is required, the first limiting plate 80402 can be directly controlled to disengage from the first limiting groove 606 to directly disassemble the processing structure, which improves the ease of use of the processing equipment and the maintenance efficiency.

[0070] Based on the aforementioned pressure-self-adjusting fireproof door panel processing equipment, this invention also proposes a processing method for the pressure-self-adjusting fireproof door panel processing equipment. For example, the processing method includes:

[0071] The four sets of sensor fixing mechanisms are used to splice and fix the edge strips of the fire door frame;

[0072] The control welding module welds the joints of the door frame;

[0073] The four sets of sensor fixing mechanisms are used to fix the fire door panel directly below the door frame;

[0074] Control the self-adjusting machining mechanism to move horizontally;

[0075] The self-adjusting processing mechanism monitors the inner wall of the door frame in real time and adjusts the corresponding processing pressure accordingly;

[0076] The four edges of the fire door panel are processed sequentially.

[0077] Complete the processing of fireproof door panels.

[0078] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
