Description

Technical Field

[0001] This invention relates to the field of metal plastic processing technology, and in particular to a fully automatic flange sealing device for aerosol fire extinguishing equipment. Background Technology

[0002] The extrusion flanging process for barrel-shaped structures is a key technological solution developed by modern industry to meet the demand for large-scale production of high-performance, lightweight, thin-walled metal containers. As a composite forming process, "extrusion flanging" can simultaneously achieve edge flanging of the workpiece and thin the flange area through extrusion, ultimately resulting in edge features with superior strength, higher dimensional accuracy, and more complex structural morphology. This effectively meets the dual requirements of thin-walled containers for edge mechanical properties and appearance precision.

[0003] Chinese patent CN06001222B discloses a compression-type bottle cap flanging device. A positioning roller for placing bottle caps is connected to the top surface of the operating table, and a motor for driving the positioning roller to rotate is installed on the support foot. Two pressure rollers that cooperate with the positioning roller to squeeze the edge of the bottle cap are slidably installed on the bottom surface of the operating table. The operating table is also provided with a bottle cap clamping mechanism that acts on the upper half of the positioning roller. The bottle cap clamping mechanism and the pressure rollers work together to achieve radial positioning of the bottle cap and improve the flanging accuracy.

[0004] However, this technical solution uses a dual-roller symmetrical extrusion method, which does not solve the problem of excessive deformation in a single extrusion causing wrinkles, cracks or metal fatigue on the workpiece edge, resulting in a high workpiece scrap rate. In addition, the device only performs flanging on the barrel structure itself and does not involve the installation and positioning of the parts inside the barrel, making it difficult to achieve high-precision positioning and automated production of the internal parts. This is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the issue of workpiece defects caused by concentrated deformation during a single extrusion in the aforementioned solutions, this invention provides a fully automatic flanging and sealing device for aerosol fire extinguishing equipment. By setting up a first, second, and third rolling station with mutually perpendicular axes, and distributing the horizontal radial displacement of the three rolling wheels in a stepped manner, the device performs multiple continuous extrusion rolling operations on the barrel-shaped structure to be processed. This effectively reduces material stress concentration, preventing defects such as wrinkles, cracks, or thinning of the edges caused by instantaneous overload in the metal material. The device significantly improves the flatness of the rolled edge, meeting the requirements for sealing performance and appearance quality, achieving high precision in the rolling process. Combined with a feeding mechanism and a positioning mechanism, it enables fully automated production of the workpiece throughout the entire process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic flange sealing device for aerosol fire extinguishing systems includes: A machining base, on which several driving components are provided; The feeding mechanism includes a conveyor belt and a feeding device disposed on the outside of the conveyor belt.

[0007] As an improvement, the rotary tensioning mechanism includes: Driven gear, wherein a plurality of curved track grooves are formed on the driven gear; A drive gear meshes with the driven gear for transmission, and the input end of the drive gear is keyed to the output shaft of the motor located above it; A fixed plate is connected to the driven gear via a rigid long shaft. The fixed plate is petal-shaped, and each petal has a straight guide slot. A sliding plate, the sliding plate being T-shaped, having an arc-shaped front end and a cylindrical guide protrusion on its vertical side, which mates with the track groove on the driven gear and the slot on the fixed plate; and The tensioning plate is arc-shaped, with a curved upper part and a straight lower part. The tensioning plate is matched and connected to the front end of the arc-shaped structure of the sliding plate.

[0008] As an improvement, the first rolling station, the second rolling station, and the third rolling station are all equipped with edge rolling wheels. The displacement of the first rolling station, the second rolling station, and the third rolling station along the horizontal radial direction close to the positioning mechanism is distributed in a stepped increasing manner. The maximum radial displacement of the first rolling station is less than the maximum radial displacement of the second rolling station, and the maximum radial displacement of the second rolling station is less than the maximum radial displacement of the third rolling station.

[0009] As an improvement, the first rolling station, the second rolling station and the third rolling station are all equipped with a cylinder drive unit. The piston rod end of the cylinder drive unit is connected to the edge rolling wheel bracket to realize the radial displacement adjustment of the rolling station.

[0010] As an improvement, the inlet end of the positioning guide component is flared outward in a funnel shape, and the whole is arranged in a funnel shape on the conveyor belt, with the width of its outlet neck matching the outer diameter of the workpiece.

[0011] As an improvement, the feeding device includes a third driving member and a first gripping device disposed at its end.

[0012] As an improvement, a push cylinder is provided below the chuck, and the cylinder rod of the push cylinder passes through the chuck. The outer diameter of the cylinder rod is adapted to the inner diameter of the workpiece. In the initial state, the end face of the cylinder rod is flush with the table surface of the machining seat.

[0013] As an improvement, the extrusion and flanging device further includes fasteners and connectors. The fasteners are high-strength bolts with anti-loosening washers and are disposed on the connectors. The fasteners are connected to the first rolling station, the second rolling station and the third rolling station respectively through the connectors.

[0014] As an improvement, both the first gripping device and the second gripping device are pneumatic grippers, and the head of the pneumatic gripper is fitted with a wear-resistant rubber pad.

[0015] As an improvement, the controller is equipped with an alarm module containing an audible and visual alarm unit, which is connected to the infrared sensor of the device; wherein the infrared sensor is mounted on the front column of the processing table.

[0016] The beneficial effects of this invention are as follows: (1) This invention uses three rolling stations with mutually perpendicular axes and uniformly distributed along the circumference, combined with a step-by-step design of horizontal radial displacement, to achieve multiple continuous and progressive extrusions on the edge of the barrel structure. This decomposes the total deformation into multiple small deformations, effectively disperses material stress, avoids defects such as wrinkles, cracks, and thinning of the edges caused by concentrated deformation in a single step, significantly improves the flatness of the rolled edge and the forming accuracy, and ensures the sealing performance and appearance quality of the product.

[0017] (2) The present invention ensures that the barrel structure rotates stably and without eccentric sway during processing by arranging the first driving component and the chuck coaxially in the vertical direction in the positioning mechanism and combining the special design of the rotation tensioning structure; the vertical distribution design of the three rolling stations forms uniform force in the whole circumference, and with the precise drive of the driving cylinder, it further ensures the consistency of the rolling edge in the circumferential direction. (3) By setting up an automatic feeding mechanism and configuring positioning guide components, sensors and gripping devices, the present invention ensures that the workpiece to be processed is accurately positioned along a preset path during the conveying process, avoiding feeding misalignment caused by workpiece offset; at the same time, the sensor detects the workpiece position in real time and triggers the gripping device to act, realizing the automatic and seamless connection of the workpiece from the conveying station to the processing station, which not only greatly reduces the error caused by manual intervention, but also ensures feeding efficiency and consistency.

[0018] (4) The controller of the present invention integrates start, run and emergency stop functions. The configured sound and light alarm module is linked with the infrared sensor, which can monitor the equipment operation status in real time and sense the human hand entering the operation area. When abnormal working conditions occur, it can promptly alarm and trigger a safe shutdown, thereby improving the safety of operation.

[0019] (5) The present invention is also provided with a flipping mechanism, which adopts the cooperation of a screw mechanism and a transmission nut, and can add a flipping action on the basis of linear conveying to meet the posture conversion requirements of the workpiece between different processing steps and realize the extrusion and flanging processing of both ends of the workpiece.

[0020] (6) The present invention uses a positioning mechanism to pick up and put down the hollow barrel during the flanging process and the non-hollow barrel after flanging. The clamping and positioning accuracy is high, and a set of clamping and positioning mechanisms can complete the high-precision picking and putting down of multi-state parts, thereby improving the positioning accuracy of the material picking and putting process. In particular, when the gap between the cylindrical workpiece A and the cylindrical workpiece B is small, the positioning mechanism of the present invention can efficiently and quickly insert the cylindrical workpiece B into the workpiece A with high precision.

[0021] In summary, this invention, through multi-dimensional structural optimization and functional design, comprehensively breaks through the technical limitations of traditional extrusion and flanging equipment, and achieves high-precision, fully automatic flanging of aerosol fire extinguishing devices.

[0023] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Example like Figure 1-2 As shown, an automatic flanging and sealing device for aerosol fire extinguishing includes: a processing base 1, a feeding mechanism 2, a positioning mechanism 3, an extrusion flanging device 4, a flipping mechanism 5, and a controller 6. The processing base 1 is provided with a plurality of driving components; the processing base 1 is provided with a support base 11, and a first driving component 12 is provided above the support base 11.

[0025] The feeding mechanism 2 includes a conveyor belt 21 and a feeding device disposed on the outside of the conveyor belt 21. The feeding device includes a third driving component 23 and a first gripping device 24 disposed at its end. The conveyor belt 21 can realize the continuous conveying of the workpiece to be processed, meeting the needs of large-scale production. It is provided with a positioning guide component 22. The end of the positioning guide component 22 is provided with a sensor. The sensor is electrically connected to the feeding device. When the workpiece reaches the designated position, the sensor drives the feeding device to grip the workpiece to the feeding position. There is no need for manual intervention in positioning and feeding, which not only reduces the error of manual operation, but also improves the feeding efficiency and avoids production interruptions caused by uneven manual feeding speed.

[0026] Preferably, the inlet end of the positioning guide component 22 is flared outward in a funnel shape and is set on the conveyor belt 21 in an overall funnel shape. The width of its outlet neck is adapted to the outer diameter of the workpiece. It can automatically calibrate and limit the posture of the workpiece during the conveying process, avoid the workpiece from shifting or stacking, ensure the consistency of the feeding posture, and provide a prerequisite for subsequent precise processing.

[0027] The positioning mechanism 3 includes a rotary tensioning mechanism 31 and a chuck 32. The first driving member 12 and the chuck 32 are arranged coaxially in the vertical direction to ensure that when the first driving member 12 drives the rotary tensioning mechanism 31 to move, the power transmission is accurate and without deviation, avoiding the positioning deviation of the processed part caused by insufficient coaxiality, and improving the dimensional accuracy of the flange seal.

[0028] The first driving member 12 is also provided with the rotary tensioning mechanism 31 at its end. The mechanism is adjustable via an inner hole, serving to ensure concentricity between the workpiece and the clamping position. It is worth noting that the rotary tensioning mechanism 31 includes: Driven gear 311, the driven gear 311 is provided with a plurality of curved track grooves 3111; A drive gear 312 meshes with the driven gear 311 for transmission, and the input end of the drive gear 312 is keyed to the output shaft of the motor 313 located above it. The fixed plate 314 is rotatably mounted on the driven gear 311. The fixed plate 314 is petal-shaped, and each petal is provided with a straight guide slot 3141. The sliding plate 315 is T-shaped, with an arc-shaped front end and a cylindrical guide protrusion on its vertical side. The guide protrusion engages with the track groove 3111 on the driven gear 311 and the slot 3141 on the fixed plate 314. The linear guide slot 3141 of the fixed plate 314 and the cylindrical guide protrusion of the sliding block 315 form a double guide, allowing the sliding block 315 to move smoothly along the track groove 3111 under the drive of the driven gear 311. The tension plate 316 is arc-shaped, with a curved upper part and a straight lower part. The tension plate 316 cooperates with and connects to the front end of the arc-shaped structure of the sliding plate 315, so that the tension plate 316 can fit against the inner wall of the workpiece and apply force evenly, avoiding excessive local force that could cause deformation of the thin-walled workpiece. At the same time, it can achieve centering and clamping of the workpiece, ensuring the coaxiality of the subsequent flanging process and further ensuring the processing accuracy.

[0029] Meanwhile, the rotary tensioning mechanism 31 can internally support and clamp the cylindrical workpiece A and externally clamp the cylindrical workpiece B, and accurately position the alternating feeding process of the two, so as to realize the alternating feeding of two different workpieces, ensure the accuracy of repeated positioning of the two workpieces, and improve the degree of automation.

[0030] Preferably, a pushing cylinder 33 is provided below the chuck 32. The cylinder rod of the pushing cylinder 33 passes through the chuck 32, and the outer diameter of the cylinder rod is adapted to the inner diameter of the workpiece. By lifting the cylinder rod, the vertical height of the workpiece A is positioned and limited. At the same time, after processing, the workpiece can be pushed out of the chuck 32, which is convenient for the subsequent flipping mechanism 5 to grasp, realizing a smooth connection between processing and unloading. The chuck 32 has the functions of clamping the workpiece and driving the workpiece to rotate, which is the prior art, and the detailed structure will not be described in detail in this application.

[0031] The extrusion and flanging device 4 includes a first rolling station 41, a second rolling station 42, and a third rolling station 43. The first rolling station 41, the second rolling station 42, and the third rolling station 43 are evenly arranged circumferentially around the outer periphery of the positioning mechanism 3, and the axes of the first rolling station 41, the second rolling station 42, and the third rolling station 43 are perpendicular to each other. It can apply uniform rolling pressure to the edge of the workpiece from multiple directions, avoid deformation of the workpiece caused by unilateral force, ensure the roundness and flatness of the edge of the workpiece after flanging, and meet the strict requirements of the sealing performance of the aerosol fire extinguishing device for the edge shape.

[0032] It should be noted that this application achieves high-precision flanging of cylindrical parts by using a design of multiple, continuous extrusion methods with different extrusion amounts. At the same time, when part B is placed inside the processed part A, high-precision flanging and sealing of both parts are achieved.

[0033] Preferably, the first rolling station 41, the second rolling station 42, and the third rolling station 43 are all edge rolling wheels. The displacement of the first rolling station 41, the second rolling station 42, and the third rolling station 43 along the horizontal radial direction near the positioning mechanism 3 is distributed in a stepped increasing manner. The maximum radial displacement of the first rolling station 41 is less than the maximum radial displacement of the second rolling station 42, and the maximum radial displacement of the second rolling station 42 is less than the maximum radial displacement of the third rolling station 43. This allows the flanging process to be completed in stages—the first rolling station 41 performs pre-rolling and shaping, the second rolling station 42 completes semi-forming processing, and the third rolling station 43 performs final shaping and finishing. Step-by-step processing can disperse the material deformation stress, avoid material cracking and edge wrinkling caused by excessive force in a single operation, and at the same time increase the material density of the flanging area, enhance the edge structural strength, and meet the requirements of the fire extinguishing device for the shell's pressure resistance and deformation resistance.

[0034] Preferably, the first rolling station 41, the second rolling station 42, and the third rolling station 43 are all equipped with cylinder drive units. The piston rod end of the cylinder drive unit is connected to the rolling wheel bracket, which can accurately control the radial displacement of the rolling wheel. The displacement can be adjusted according to the flanging requirements of workpieces of different specifications, adapting to the processing of multiple models of aerosol fire extinguishing devices and improving the flexible production capacity of the equipment. At the same time, the cylinder drive has a fast response speed and can quickly switch processing states, further improving production efficiency.

[0035] Preferably, the extrusion and flanging device 4 further includes a fastener 44 and a connector 45. The fastener 44 is a high-strength bolt with an anti-loosening washer, which is disposed on the connector 45. The fastener 44 is connected to the first rolling station 41, the second rolling station 42 and the third rolling station 43 respectively through the connector 45, ensuring that the station will not loosen or shift due to vibration during the rolling process, thus ensuring the stability of the processing parameters. The anti-loosening washer design can also cope with vibration loss during long-term operation of the equipment, extend the service life of the equipment and reduce the maintenance frequency.

[0036] The flipping mechanism 5 includes a lead screw mechanism 51 and a transmission nut 52 disposed on the lead screw mechanism 51. The lead screw mechanism 51 and the transmission nut 52 cooperate to realize the smooth linear transfer of the workpiece, avoiding the workpiece falling off or shifting its posture due to inertial shaking. A fixing block 53 is provided above the transmission nut 52. A second driving member 54 is provided on the fixing block 53. A second gripping device 55 is provided at the end of the second driving member 54. The second driving member 54 can drive the second gripping device 55 to realize the flipping action (such as 0-180° posture adjustment), which can change the processed workpiece from the processing posture to the posture required for subsequent flanging.

[0037] Preferably, both the first gripping device 24 and the second gripping device 55 are pneumatic grippers. The head of the pneumatic gripper is fitted with a wear-resistant rubber pad, which has the advantage of stable gripping force and is suitable for thin-walled metal aerosol fire extinguishing device workpieces. The wear-resistant rubber pad embedded in the gripper head can increase the friction with the workpiece, prevent the workpiece from slipping during gripping, and avoid hard contact that could scratch the workpiece surface, thus ensuring the appearance quality of the workpiece.

[0038] The controller 6 is integrated and installed on the table of the processing base 1. It is used to realize the functions of starting the equipment, adjusting the operating parameters and emergency stopping. It is convenient for operators to monitor the operating status of the equipment in real time. The operating parameters (such as rolling displacement, drive speed, etc.) can be flexibly adjusted through the human-machine interface to adapt to different processing needs. There is no need to manually adjust each mechanism, which improves the convenience of operation.

[0039] Preferably, the controller 6 is equipped with an alarm module including an audible and visual alarm unit. The alarm module is connected to the infrared sensor 13 of the equipment to detect in real time whether there are personnel accidentally entering the processing area or abnormal workpieces. Once the alarm is triggered, the audible and visual signals can promptly remind the operator to handle the situation, ensuring production safety and equipment stability, and reducing the risk of safety accidents and product scrap. In particular, the infrared sensor 13 is installed on the front column of the processing table 1, which can more accurately detect personnel accidentally entering the processing area and ensure operational safety.

[0040] Work steps (1) After the controller 6 starts the equipment, it takes two workpieces: cylindrical workpiece A and cylindrical workpiece B (workpieces of the same specification) and places workpiece A and workpiece B alternately on the conveyor belt 21 of the feeding mechanism 2. The conveyor belt 21 drives the workpiece to move along the preset path. During the process, the positioning guide component 22 on the conveyor belt 21 performs posture calibration on the workpiece. When the workpiece moves to the end of the positioning guide component, the sensor detects the position of the workpiece and sends an electrical signal to the feeding device. The third drive component 23 of the feeding device drives the first gripping device 24 to move, accurately clamping workpiece A and moving it to the processing position of the positioning mechanism 3 (directly above the chuck 32), realizing the automated connection of feeding; (2) During the transfer process, the first driving member 12 drives the rotary tensioning mechanism 31 to descend, so that the tensioning plate 316 of the rotary tensioning mechanism 31 is inserted into the workpiece A. Subsequently, the motor 313 of the rotary tensioning mechanism 31 drives the driving gear 312 to rotate. The driving gear 312 meshes and drives the driven gear 311 to rotate, pushing the sliding block 315 to move radially along the slot of the petal-shaped fixing plate 314, thereby driving the tensioning plate 316 to expand, so that the straight arc surface of the tensioning plate 216 is tightly attached to the inner wall of the workpiece A, and the expansion makes its inner diameter the same as that of the rotary tensioning mechanism 31, so as to achieve the internal support clamping of the cylindrical workpiece A. (3) During the process of the workpiece A falling to the processing position, it is aligned with the axis and falls onto the push cylinder 33 in the chuck 32. The push cylinder 33 is started, and its cylinder rod extends upward to support the bottom of the workpiece A. Then the rotating tensioning mechanism 31 contracts, rises above the workpiece A, expands again, and falls down to press the workpiece A. At the same time, the chuck 32 clamps, realizing the centering and clamping of the workpiece. (4) After positioning, the extrusion and flanging device 4 is started: the cylinder drive units of the three rolling stations drive the rolling wheels to approach the edge of the workpiece A along the horizontal radial direction. The first rolling station 41 first performs a small-angle preliminary flanging and extrusion on the edge of the workpiece. The second rolling station 42 then increases the flanging angle and further extrudes and thins the edge. The third rolling station 43 completes the final angle flanging and extrudes the edge into the final complex contour. After flanging is completed, the cylinder drive unit of the rolling station drives the rolling wheels to reset, the rotating tensioning mechanism 31 retracts, and the cylinder 33 drives the cylinder rod to descend to the initial state flush with the table surface of the processing seat 1. The chuck 32 is released, and the first flanging process is completed. (5) Then the flipping mechanism 5 is started, and its lead screw mechanism 51 drives the transmission nut 52 to move along the preset trajectory. The second drive member 54 drives the second gripping device 55 to move directly above the workpiece A. After the second gripping device 55 clamps the workpiece A, the second drive member 54 drives the workpiece to flip 180° (adjust to the other end to be flipped). At the same time, the feeding mechanism 2 repeats the action of step 1. After the sensor on the positioning guide assembly 22 senses the workpiece B, the first gripping device 24 moves the workpiece B to the processing position. (6) After the workpiece A is flipped, the flipping mechanism 5 moves the workpiece A to the conveyor belt 21 and resets it. It waits for one end of the workpiece B to be flipped. The flipping mechanism 5 clamps the workpiece B. At the same time, the feeding mechanism 2 repeats the action of step 1. After sensing the workpiece A, the first gripping device 24 moves the workpiece A to the processing position to perform the flipping process on the other end. The workpiece B then repeats the process of the workpiece A, and thus alternately completes the flipping of both ends of the two workpieces at the same work position.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
