Description

Technical Field

[0001] The present invention relates to an automatic forming device for metal barrier explosion suppression materials, belonging to the technical field of forming and processing of explosion suppression materials. Background Art

[0002] Metal barrier explosion suppression materials are widely used in tanks filled with flammable and explosive fluid media. When the tank suffers an accidental accident such as impact and generates a fire source, it can effectively inhibit the explosion of the tank body.

[0003] CN 117206404 A discloses a processing device for special alloy mesh barrier explosion-proof materials, CN 109650145 A discloses a device for preparing barrier explosion-proof materials, and CN 208527831 U discloses a special production device for barrier explosion-proof materials. These technologies are all for the equipment in the process of slitting and stretching the barrier explosion-proof materials, and do not involve the process of coil forming.

[0004] Most of the existing explosion suppression material forming devices focus on the web forming device. CN 108249221 B discloses a bilateral inward rolling forming device for barrier explosion-proof materials. The material targeted by this forming device is relatively large in volume and is mainly applicable to large tanks; for the filling of explosion suppression materials in small-volume tanks and oil tanks with special structures, explosion suppression forming materials with relatively small specifications are mainly used. Due to the lack of research on the coil forming equipment for this part, and due to the flexibility of its size and the variability of its structure, the material forming conditions are complex. Therefore, this forming material still relies on manual coil forming. Manual coil forming has low production efficiency, high forming variability, and it is difficult to ensure the dimensional uniformity of the formed material, and the filling density of the material will directly affect its explosion suppression performance. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic forming device for metal barrier explosion suppression materials to solve the existing key problems aiming at the problems of low filling density in small-volume tanks and tanks with special structures, low manual production efficiency, and inconsistent dimensions of formed products affecting the filling rate.

[0006] The technical solution of the present invention is as follows: An automatic forming device for metal barrier explosion suppression materials, the device includes a feeding conveying mechanism, a coil forming mechanism, and a discharging conveying mechanism. Among them, the feeding conveying mechanism is composed of an adjustable lifting conveyor belt, a fixed conveyor belt, an adjustment driving mechanism, and a transmission mechanism; the coil forming mechanism is installed on the right side of the feeding conveying mechanism, and there are three coil devices with different specifications on the coil forming mechanism. Each coil device is provided with a coil support column on the coil reel, and a limit pressing piece is installed on the outer edge of the coil reel; the discharging conveying mechanism is located below the coil forming mechanism, equipped with a hydraulic lift, a lifting platform frame and a conveyor belt, and there are hydraulic load-bearing devices and lifting guide rails at both ends.

[0007] Furthermore, in the feeding and conveying mechanism, an adjustable conveyor belt is installed above the fixed conveyor belt. In the adjustment driving mechanism, the lead screw limit blocks are respectively installed on the adjustable conveyor belt frame and the fixed conveyor belt support frame, the nut slider is installed on the adjustable conveyor belt support frame, the lead screw driving motor is located at the lower edge of the fixed conveyor belt, and the transmission mechanism is composed of a baffle, a conveyor belt, a support frame, a driving shaft, and a roller.

[0008] Furthermore, in the coiling and forming mechanism, the coiling reel in the coiling device is connected to the coiling mechanism chassis through a shaft. There are support pillar tracks in the coiling reel, and coiling support pillars are arranged in the tracks. The forming push piece is installed on the surface of the coiling reel. A limiting pressure piece is provided at the outermost edge of the coiling reel, and the limiting pressure piece is connected to the coiling mechanism chassis through a pressure piece guide rail on the coiling mechanism chassis.

[0009] Furthermore, in the coiling and forming mechanism, the coiling mechanism chassis is connected to an external moving arm through a shaft. A base is provided below the moving arm and is connected to a moving guide rail through a sliding platform. A moving arm lead screw is arranged in the middle of the guide rail, and a moving arm driving motor is installed on the right side.

[0010] Furthermore, in the coiling and forming mechanism, the coiling mechanism chassis is connected to an external moving arm through a shaft and a bearing. The coiling mechanism chassis rotates according to the requirements for limiting the formed material, and thus a suitable coiling device is selected.

[0011] Furthermore, in the coiling and forming mechanism, three different coiling devices are distributed on the coiling mechanism chassis. Due to the limitation of the center void ratio of the formed material, the outer shapes of the coiling support pillars are respectively cylindrical or columnar with a kidney-shaped cross-section.

[0012] Furthermore, in the coiling and forming mechanism, there are 2 - 3 coiling support pillars. Due to the limitation of the size of the formed material, the coiling support pillars are arranged in a side-by-side or equilateral triangle distribution.

[0013] Furthermore, in the coiling and forming mechanism, the limiting pressure piece slides in the pressure piece guide rail through a pressure piece slider to restrict the diameter of the formed material.

[0014] Furthermore, in the coiling and forming mechanism, the forming push piece is located on the surface of the coiling reel and is limited by the coiling support pillars.

[0015] Furthermore, inside the chassis of the coil stock mechanism, there is a coil stock support driving mechanism, which consists of a driving base plate, a coil stock support, an annular rack, a support moving arm, a tooth groove of the support moving arm, an internal gear of the driving base plate, a support driving motor, a limit pressing plate motor, a cylinder connecting rod, a limit pressing plate lead screw, a first coil stock disk gear, a cylinder, a coil stock disk driving motor, and a second coil stock disk gear; the coil stock support is rigidly installed on the support moving arm, and the support moving arm meshes with the annular rack provided on the front of the driving base plate through four tooth grooves on the back; an internal gear of the driving base plate is provided on the back of the driving base plate, and the support driving motor is located on the back of the driving base plate and meshes with the internal gear of the driving base plate.

[0016] The beneficial effects of the present invention are as follows: Regarding the problems of low filling density of small-volume tanks and special-structured boxes, low manual production efficiency, and inconsistent sizes of formed products affecting the filling rate, etc., the present invention can not only replace manual labor to complete the coil stock forming process, but also effectively improve the production efficiency of explosion suppression materials, save labor costs, ensure the uniformity of formed products, increase the filling density of boxes, and enhance the explosion-proof performance of explosion suppression materials.

Detailed implementation mode

[0019] The content of the present invention will be described in detail with reference to the following drawings: The automatic forming device for metal barrier and explosion suppression material includes a feeding and conveying mechanism, a coil forming mechanism 5, and a discharging and conveying mechanism. As Figure 2 shown, the coil forming mechanism 5 is installed on the moving arm 6. A moving arm base 4 is provided below the moving arm 6 and is fixed to the moving arm slide 3 by bolts. The moving arm slide 3 is rigidly connected to the moving slider 2 below, and both ends are connected to the slide guide 9. The slide guide 9 is fixed on the support platform 8. A control cabinet 7 is provided on the right side of the slide guide 9. As the central device of the automatic forming device, the control cabinet 7 is internally provided with PLC control modules for the feeding and conveying mechanism, the coil forming mechanism 5, and the discharging and conveying mechanism, as well as frequency converters for each drive motor, which plays a role in protecting the circuit and control components from dust and water. The moving slider 2 is connected to the moving arm lead screw 1 by a thread, and a moving arm drive motor 11 is provided on the right side of the moving arm lead screw 1 and is connected through the moving arm coupling 10.

[0020] As Figure 1 shown, the feeding and conveying mechanism is installed on the left side of the coil forming mechanism 5. AsFigure 5 As shown, the feeding conveying mechanism consists of a fixed conveyor belt 23 and an adjustable conveyor belt 24; as Figure 4 shown, in the adjustment driving mechanism, the lead screw driving motor 32 and the adjustment lead screw 30 are connected by a coupling. There are a lead screw limit slider 28, a second lead screw limit block 31, and a nut slider 29 on the lead screw respectively. Ball roller bearings are provided in the lead screw limit blocks to prevent displacement when the lead screw rotates; mounting support frames 25 are provided on the feeding roller shafts 26 of both the adjustable conveyor belt 24 and the fixed conveyor belt 23, and the nut sliders 29 are rigidly connected to the support frames 25.

[0021] During adjustment, first, the lead screw driving motor 32 drives the adjustment lead screw 30 to rotate. The nut slider 29 on the adjustment lead screw 30 is displaced under the action of the thread, and the nut slider 29 is rigidly connected to the support frame 25, thereby realizing the up and down displacement of the support frame 25 and the adjustable conveyor belt 24. The transmission mechanism consists of a baffle 22, an adjustable conveyor belt 24, a support frame 25, a feeding roller shaft 26, and a feeding roller 27. The distance between the fixed conveyor belt 23 and the adjustable conveyor belt 24 is as Figure 6 shown at 33 in the figure. Its spacing needs to be adjusted with reference to the folding thickness of the material to ensure that the width of the web after folding is not damaged during the coiling process of the coiling device.

[0022] As Figure 1 shown, the discharging conveying mechanism is installed below the coiling forming mechanism 5. As Figure 8 shown, the discharging conveying mechanism consists of a discharging conveyor belt 41, a discharging roller 43, a lifting platform frame 40, a fixed platform frame 45, a discharging machine frame 42, a hydraulic elevator 37, a hydraulic load bearing device 38, a lifting guide rail 46, a discharging collection box 47, etc.; the fixed platform frame 45 and the lifting platform frame 40 are fixed side by side on the ground, and a discharging machine frame 42 is provided above. The inside of the guide rail cap 44 is tightly fitted with the lifting guide rail 46, and the bottom surface of the guide rail cap 44 is fixedly connected to the discharging machine frame 42; a discharging conveyor belt 41 is installed in the middle of the lifting platform frame 40. The roller shaft of the discharging conveyor belt 41 is fixed to the fixed platform frame 45 by bolts, and a hydraulic elevator 37 is provided below.

[0023] As Figure 9As shown in the figure, the upper part of the hydraulic lift 37 is rigidly connected to the lifting platform frame 40 through the connecting rod 49, and the lower part is connected to the ground through the hydraulic press gasket 50. The housing is connected to the ground through the hydraulic press support 39 (During operation: When the hydraulic lift 37 is started, under the action of the ground and the hydraulic press support 39, the lifting platform frame 40 is pushed through the connecting rod 49 to achieve the lifting function); In the middle of the fixed platform frame 45, there is a discharge roller 43 connected to the platform through bolts, and a discharge collection box 47 is provided below. The discharge collection box 47 is only placed on the ground and can be replaced at any time; On both sides of the lifting platform frame 40, there are hydraulic load-bearing devices 38. The upper part of the hydraulic load-bearing device 38 is connected to the lifting platform frame 40, and the lower part contacts the ground through the support plate 48; The lifting guide rails 46 are respectively arranged on both sides of the lifting platform frame 40 and the fixed platform frame 45. The upper end of the lifting guide rail 46 is fixed to the discharge machine frame 42, and the lower end contacts the ground through the support plate 48.

[0024] As Figure 3 shown in the figure, three coiling devices with different functions are respectively installed on the coiling mechanism chassis 18. Each coiling device is composed of a pressing piece track 17, a pressing piece slider 19, a limiting pressing piece 15, a forming pushing piece 12, a pillar track 13, a coiling disk 14, a first pressure sensor 16, and a second pressure sensor 20; Among them, the coiling pillars 21 of different coiling devices have different structures. According to the forming requirements such as the hollow rate and external dimensions of the material forming, a suitable coiling device is selected; The limiting pressing piece 15 adjusts its working position according to the external dimension requirements of the forming material. As Figure 7 shown in the figure, the coiling forming mechanism 5 and the moving arm 6 are connected through the coiling mechanism chassis transmission shaft 35 to realize the rotation of the coiling mechanism chassis; Similarly, the coiling disk 14 and the coiling mechanism chassis 18 are driven and connected through a double-row angular contact ball bearing 34 and a coiling disk shaft 36.

[0025] Inside the coiling mechanism chassis, there is a coiling pillar driving mechanism as Figures 10 to 12 shown in the figure. The coiling pillar driving mechanism is composed of a driving base plate 51, a coiling pillar 21, an annular rack 52, a pillar moving arm 53, a pillar moving arm tooth groove 54, an internal gear of the driving base plate 55, a pillar driving motor 56, a limiting pressing piece motor 57, a cylinder connecting rod 58, a limiting pressing piece lead screw 59, a first coiling disk gear 60, a cylinder 61, a coiling disk driving motor 62, and a second coiling disk gear 63. The coiling pillar 21 is rigidly installed on the pillar moving arm 53. The pillar moving arm 53 meshes with the annular rack 52 provided on the front of the driving base plate 51 through four pillar moving arm tooth grooves 54 on its back; The driving base plate 51 is provided with an internal gear of the driving base plate 55 on its back, and the pillar driving motor 56 is located on the back of the driving base plate 51 and meshes with the internal gear of the driving base plate 55.

[0026] As Figures 10 to 12When the coil stock support column 21 is opened, the support column drive motor 56 rotates forward. Through the meshing action of the inner gear 55 of the drive base plate, the drive base plate 51 and the annular rack 52 rotate simultaneously. Since the support column moving arm 53 does not perform a circular motion with the drive base plate 51, and the tooth grooves 54 of the support column moving arm mesh with the annular rack 52, as the annular rack 52 continuously rotates, the annular rack 52 gradually meshes with the empty tooth grooves of the support column moving arm 53, forming a three-jaw centering mechanism. When the drive base plate 51 rotates one full circle, the support column moving arm 53 translates by one tooth groove position. Therefore, the rotational motion of the drive base plate 51 is transformed into the linear motion of the support column moving arm 53. Since the coil stock support column 21 is fixed to the support column moving arm 53, the coil stock support column 21 moves towards the outer edge of the coil stock reel 14, realizing the opening action of the coil stock support column 21. Similarly, when the support column drive motor 56 rotates in reverse, the clamping action of the coil stock support column 21 can be realized.

[0027] The air cylinder 61 is fixedly connected to the forming push plate 12 through the air cylinder connecting rod 58; when the coil stock is completed, the air cylinder 61 pushes the forming push plate 12 to displace outward through the air cylinder connecting rod 58, realizing the ejection of the material.

[0028] The limit pressing plate 15 is connected to the limit pressing plate motor 57 through the pressing plate slider 19 and the limit pressing plate lead screw 59. The pressing plate slider 19 is provided with a reverse spiral thread; when adjusting the limit pressing plate 15, the limit pressing plate motor 57 drives the limit pressing plate lead screw 59 to rotate together. The limit pressing plate 15 is fixedly connected to the pressing plate slider 19. Under the meshing action of the pressing plate slider 19 and the lead screw 59, the limit pressing plate 15 moves, realizing the adjustment function.

[0029] Working process: First, place the folded material after cutting and sewing the net at the feeding port of the fixed conveyor belt 23 of the feeding conveyor mechanism. The material is transported to the adjustable conveyor belt 24 through the conveyor belt. Adjust the adjustment distance 33 between the two conveyor belts according to the thickness requirement of the folded material. After passing through the adjustable conveyor belt 24, the extruded material is transported to the coil forming mechanism 5; the coil stock support column 21 of the coil stock device is opened under the action of the support column drive mechanism. After the material moves a certain length past the support column, the coil stock support column 21 continues to perform a clamping action (the clamping distance is set according to the material thickness) under the movement of the support column drive mechanism. After clamping, the coil stock reel 14 rotates, driving the coil stock support column 21 to rotate around the center of the coil stock reel 14 to realize the coil stock action. The limit pressing plate 15 adjusts the position of the limit pressing plate according to the size requirement of the formed material, forming a constraint condition for the coil stock forming diameter size. After the coil stock is completed, the formed coil is ejected through the forming push plate 12. The lifting platform 40 is adjusted under the action of the hydraulic lift 37 according to the product size. After passing through the discharge conveyor belt 41 and the discharge roller 43, the product is transported to the discharge collection box 47, completing the coil stock process.

[0030] The above are only embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
