Description

Technical Field

[0001] The invention relates to the technical field of integrated stamping, in particular to a pressure vessel steel plate blanking plasma cutting machine. Background Art

[0002] Pressure vessels are enclosed devices that contain gases or liquids and bear a certain pressure. To more effectively implement scientific management and safety inspections, my country's "Regulations on Safety Supervision of Pressure Vessels" classify pressure vessels into three categories based on operating pressure, medium hazard, and their role in production.

[0003] A pressure vessel is a sealed container that can withstand pressure. It has a wide range of uses and plays an important role in many departments and many fields of scientific research.

[0004] Among them, the most widely used are in the chemical industry and the petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels.

[0005] The top of the pressure vessel is usually circular, which can prevent the top from deforming when the pressure inside the container increases. The top of the container is usually obtained by cutting and stamping steel.

[0006] The existing production steps are: circular cutting of plates - circular plate collection - transfer to stamping equipment - stamping of circular plates to obtain semicircular top covers. The steps are relatively complicated and the integration is low.

[0007] The reason why existing equipment does not combine cutting equipment and stamping equipment is that existing cutting equipment usually slides on multiple axes to achieve cutting of multiple plates of required shapes on a plate, and the cutting positions are different, which makes it difficult to transfer the cut plates to the stamping equipment.

[0008] Of course, this can be achieved through the coordinated work of robotic arms and cylinders, but the procurement, debugging, use, and maintenance costs of this method are too high, and the cost difference is too large compared to step-by-step processing. Summary of the Invention

[0021] Furthermore, the rolling turning assembly includes a U-shaped base, the base is horizontally slidably mounted on the connecting seat, the connecting seat is provided with a rack portion integrally formed therewith, the rack portion meshing with a third gear rotatably mounted on the base;

[0022] A No. 2 gear is fixed on one side of the base, and a No. 1 gear is coaxially fixed on the transmission shaft and meshes with the No. 2 gear;

[0023] The third gear is fixed coaxially with the end of the sleeve away from the slide plate;

[0024] Drive assemblies are mounted on both sides of the abutment.

[0025] Furthermore, the travel limiting member includes a limiting groove provided on a side opposite to the electromagnet connecting portion, and limiting blocks slidably installed in the limiting groove are fixed on both sides of the slide.

DETAILED DESCRIPTION

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0057] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0058] The following is based on Figures 1-16 The present invention describes a pressure vessel steel plate blanking plasma cutting machine provided by an embodiment of the present invention.

[0059] See also Figures 1-16 An embodiment of the present invention provides a plasma cutting machine for blanking steel plates for pressure vessels, comprising a machine platform 1 and a carrier frame 2 slidably mounted on the machine platform 1, a grid 101 being fixed on the machine platform 1, and slides 301 slidably mounted on both sides of the machine platform 1, the two slides 301 being connected by a rectangular rod, a slide 3 being slidably mounted on the rectangular rod, a lifting plate 303 being slidably mounted on the slide 3 toward one side of the carrier frame 2, and a cutting gun 302 being fixed on the lifting plate 303.

[0060] like Figure 1 、 Figure 4-Figure 7 As shown, a lower press 204 is also provided, and the lower press 204 is slidably installed on the carrier frame 2. Two guide rods 203 are fixed on both sides of the lower press 204. An upper press 202 cooperating with the lower press 204 is slidably installed on the guide rods 203. Axial holes 2015 are opened on the tops of the four guide rods 203. A follower frame 201 fixed to the slide 3 is slidably installed in the axial holes 2015. A loading mechanism is installed on the side of the lower press 204 facing the slide 3, and a blanking component is installed on the side of the lower press 204 away from the slide 3.

[0061] A movable groove 2014 is also provided on the lower pressing tool 204 , and an ejection assembly is installed in the lower pressing tool 204 for ejecting the workpiece after the stamping is completed.

[0062] In an embodiment of the present invention, the two slides 301 can slide along the length direction of the machine 1, and can drive the rectangular rod located between the two slides 301 to slide upright, the slide 3 can slide axially on the rectangular rod, and the lifting plate 303 can slide upright on the slide 3, while driving the cutting gun 302 to slide upright, wherein the upright sliding of the lifting plate 303 and the axial sliding of the slide 3 along the rectangular rod are driven by the driving member 304, so as to realize the left and right, up and down, front and back movement of the cutting gun 302 located on the machine 1.

[0063] When the slide 3 moves horizontally, it also drives the guide rod 203, the lower press 204, and the upper press 202 to move horizontally synchronously through the follower frame 201. When the slide 3 moves back and forth, that is, when it moves along the length direction of the machine 1, the follower frame 201 drives the guide rod 203, the lower press 204 and the upper press 202 to move synchronously, so that the upper press 202 and the lower press 204 always follow the slide 3 when the slide 3 moves. When the rectangular rod is driven to rise or fall through the two slides 301, the follower frame 201 will be driven to rise and fall synchronously. However, since the follower frame 201 is slidably connected to the guide rod 203, it will not drive the guide rod 203 to rise.

[0064] During processing, the plate body 4 is placed on the grid 101 on the machine table 1 , and the position of the plate body 4 is corrected so that the length plane of the plate body 4 is parallel to the length plane of the machine table 1 .

[0065] Subsequently, the cutting gun 302 is driven to work, and the forward and backward and left and right movements of the cutting gun 302 are coordinated to cut a plurality of circular plates at equal intervals on the plate body 4. Here, the present invention names the circular plates as material plates. The cut material plates will be transferred to the lower press 204 through the loading mechanism, and then pressed down by the pressing device. The pressing device can be a cylinder or a hydraulic cylinder, etc. The present invention does not make specific restrictions. Moreover, since the stamped plate of the present invention is relatively thin, the force for driving the follower frame 201 to press down is relatively low, so the equipment that can be selected is also relatively wide, and the upper press 202 is driven to descend, so that the convex surface of the top of the upper press 202 is matched with the concave surface of the top of the lower press 204 through the descent of the upper press 202, and then the upper punching force is coordinated to make the material plate be punched to the specified shape.

[0066] Among them, when the upper press 202 descends to punch the material sheet, it also triggers the ejection component to work. When the upper press 202 rises, the ejection component will be embedded in the concave surface of the lower press 204 to complete the stamping of the material sheet, so that it can be pushed out and unloaded through the unloading component to facilitate subsequent stamping.

[0067] See also Figure 7 、 Figure 8 The ejection assembly includes a lifting plate 2012 slidably mounted in a movable groove 2014 , and a spring piece 2013 is fixed to the bottom of the lifting plate 2012 .

[0068] The lower pressing tool 204 includes a base with a concave surface provided on the base, and the top of the lifting plate 2012 has the same shape as the bottom of the concave surface of the lower pressing tool 204 .

[0069] In an embodiment of the present invention, when the upper pressing tool 202 is pressed downward, downward pressure is applied to the lifting plate 2012 while driving the material plate to deform, so that the lifting plate 2012 is vertically lowered, so as to drive the spring piece 2013 to deform from a U shape to an "I" shape during the descent. In this process, the spring piece 2013 reserves elasticity. When the upper pressing tool 202 rises after the material plate is stamped, the elastic potential energy of the spring piece 2013 is released to drive the lifting plate 2012 to rise, so that the stamped material plate can be lifted up by the rise of the lifting plate 2012.

[0070] Among them, since the top of the lifting plate 2012 is the same shape as the concave bottom of the lower pressing tool 204, that is, the top surface of the lifting plate 2012 is an arc, when the lifting plate 2012 lifts the stamped material sheet, it will not fall off the lifting plate 2012.

[0071] The loading mechanism includes a connecting seat 205 slidably mounted on the carrier 2 and fixed to the lower pressing tool 204 .

[0072] A sleeve plate 208 is mounted on the connecting seat 205 via a rolling rotation assembly, a slide plate 209 is slidably mounted inside the sleeve plate 208, the sleeve plate 208 and the slide plate 209 are connected via a telescopic member, and the telescopic member is connected to the rolling rotation assembly.

[0073] An electromagnet 2010 is rotatably mounted on the end of the slide 209 .

[0074] The electromagnet 2010 includes an adsorption portion and a connection portion. The connection portion of the electromagnet 2010 is rotatably connected to the slide 209 , and a travel limiter is installed between the connection portion of the electromagnet 2010 and the slide 209 .

[0075] In the embodiment of the present invention, the plate body 4 is cut by the cutting gun 302. At the starting point and the ending point of the cutting, the electromagnet 2010 is at the center point of the cut plate. When the plate is separated from the plate body 4, it is adsorbed by the electromagnet 2010.

[0076] The sleeve plate 208 is driven by the rolling turning assembly to flip toward the lower press 204 and move toward the lower press 204. In this process, the telescopic part is also driven by the rolling turning assembly to work, and the slide plate 209 is driven by the telescopic part to retract into the sleeve plate 208. When the sleeve plate 208 flips to the end of the stroke, it is in a horizontal state, and the material plate adsorbed by the electromagnet 2010 is coaxial with the concave surface of the lower press 204. By cutting off the adsorption of the electromagnet 2010 and the material plate, the material plate falls to the concave surface of the lower press 204.

[0077] The technical effect achieved is that, due to the limitation of the movement space, such as the telescopic setting between the slide plate 209 and the sleeve plate 208, the sleeve plate 208 and the slide plate 209 will interfere with other components when flipping. The main reason is that the rotation radius of the slide plate 209 and the sleeve plate 208 is large when rotating, and reducing the length of the slide plate 209 and the sleeve plate 208 will cause the distance between the electromagnet 2010 and the material plate to be larger, and the material plate cannot be effectively adsorbed onto the electromagnet 2010. Moreover, due to the reduction in the length of the slide plate 209 and the sleeve plate 208, when the slide plate 209 and the sleeve plate 208 flip to the end of the stroke, the position of the electromagnet 2010 and the material plate cannot be in a coaxial position with the concave surface of the lower press 204.

[0078] The solution of the present application is that when the slide plate 209 and the sleeve plate 208 are flipped, the slide plate 209 is retracted into the sleeve plate 208 to reduce the rotation radius and avoid interference with other components. Since the slide plate 209 is retracted into the sleeve plate 208, the length of the slide plate 209 and the sleeve plate 208 is essentially reduced. When the sleeve plate 208 and the slide plate 209 are flipped to the end of the stroke, the electromagnet 2010 and the material plate still cannot be coaxial with the concave surface of the lower press 204. Therefore, the sleeve plate 208 in the present invention will also move toward the lower press 204 when flipping to make up for the problem of insufficient length.

[0079] The telescopic member includes a screw rod 2025 rotatably mounted in the sleeve plate 208 , and the screw rod 2025 is threadedly engaged with the internal threaded hole 502 opened at the end of the slide plate 209 .

[0080] A transmission shaft is installed on one side of the sleeve plate 208, which passes through the sleeve plate 208 and is rotatably connected thereto. The transmission shaft is connected to the screw rod 2025 through the second bevel gear set 2024, and the transmission shaft is connected to the rolling rotation assembly.

[0081] In an embodiment of the present invention, when the sleeve 208 is flipped, the transmission shaft is driven to rotate by the rolling rotation assembly. When the transmission shaft rotates, the slide plate 209 is driven to move toward the sleeve 208 through the threaded engagement with the internal threaded hole 502. When the slide plate 209 moves, the electromagnet 2010 is driven to move synchronously.

[0082] The rolling rotation assembly includes a U-shaped base 2026, which is horizontally slidably mounted on the connecting seat 205. The connecting seat 205 is provided with a rack portion 2023 integrally formed therewith, and the rack portion 2023 is engaged with the third gear 2020 rotatably mounted on the base 2026.

[0083] A second gear 2018 is fixed to one side of the base 2026 , and a first gear 2017 is coaxially fixed on the transmission shaft and meshes with the second gear 2018 .

[0084] The third gear 2020 is coaxially fixed to the end of the sleeve plate 208 away from the slide plate 209 .

[0085] Drive assemblies are mounted on both sides of the base 2026.

[0086] In the embodiment of the present invention, the third gear 2020 is driven to rotate by a driving assembly.

[0087] When the third gear 2020 rotates, it meshes with the rack portion 2023 to cause the third gear 2020 to rotate while moving toward the lower press 204. This rolling forward movement drives the sleeve 208 to flip and move toward the lower press 204.

[0088] Among them, when the sleeve plate 208 is flipped, it drives the transmission shaft and the No. 1 gear 2017 to rotate with the rotation axis of the No. 3 gear 2020 as the axis. In this process, the No. 1 gear 2017 and the transmission shaft are rotated by the engagement of the No. 1 gear 2017 and the No. 2 gear 2018. When the No. 1 gear 2017 rotates, the No. 2 bevel gear set 2024 drives the screw rod 2025 to rotate. The rotation of the screw rod 2025 corresponds to the movement of the slide plate 209 toward the inside of the sleeve plate 208.

[0089] The achieved motion state is that the sleeve plate 208 flips toward the lower press 204 with the third gear 2020 as the axis and moves horizontally toward the lower press 204 , and at the same time drives the slide plate 209 to move toward the inside of the sleeve plate 208 .

[0090] This movement state can greatly reduce the movement space required for transportation.

[0091] It should also be noted that the base 2026 includes two supporting plates, which are fixed by a connecting plate at the bottom to form a U shape. A through groove is provided on the connecting seat 205, and the connection of the base 2026 is located in the through groove.

[0092] The travel limiter comprises a limit slot 5 provided on a side opposite to the connection portion of the electromagnet 2010 , and limit blocks 501 slidably mounted in the limit slot 5 are fixed on both sides of the slide plate 209 .

[0093] In the embodiment of the present invention, after the cover plate 208 and the slide plate 209 are turned over and erected, the subsequent rotation will be driven by gravity. Figure 14 .

[0094] The cooperation between the limiting groove 5 and the limiting block 501 can quickly stabilize the electromagnet 2010 after the electromagnet 2010 is turned over, thereby reducing shaking.

[0095] As an optional embodiment of the present invention, a second electromagnet is installed at the starting end and the end end of the stroke of the limit slot 5. When the limit block 501 is at the starting end or the end end of the stroke, the second electromagnet adsorbs the limit block 501 to achieve a positioning effect and avoid shaking.

[0096] The blanking assembly includes a blanking piece 206 fixed on the carrier 2. The blanking piece 206 is arranged in an isosceles triangle shape, and a V-shaped groove 2011 is opened on the top of the blanking piece 206. The blanking piece 206 is located on the side of the lower pressing tool 204 away from the slide 3.

[0097] A blanking guide block 207 fixed to the lower pressing tool 204 is installed between the lower pressing tool 204 and the blanking piece 206 .

[0098] A pushing piece that cooperates with the blanking guide block 207 and the blanking piece 206 is installed on the connecting seat 205.

[0099] In an embodiment of the present invention, when the base 2026 moves toward the lower press 204, it drives the pushing member to work, so as to push the stamped material sheet to move through the pushing member. When the stamped material sheet moves, it is limited by the blanking guide block 207 so that it will not fall during the movement. Finally, the stamped material sheet enters the V-shaped groove 2011 of the blanking member 206.

[0100] The sheet material in the V-shaped groove 2011 will move toward one side or the other side under the action of the inclined surface at the top of the unloading member 206. Collection boxes can be fixed on both sides of the carrier 2 to collect the sheet material.

[0101] The V-shaped groove 2011 can limit and guide the material sheet on the unloading member 206 to a certain extent, so that there will not be excessive position deviation when the material sheet moves into the collection box.

[0102] The pushing member includes a sliding groove opened on the side of the connecting seat 205 facing the lower pressing tool 204, in which an extension plate 2021 is slidably installed. A fitting pushing head 2022 is fixed at the end of the extension plate 2021, and an arc surface is provided at the end of the fitting pushing head 2022.

[0103] In the embodiment of the present invention, the extension plate 2021 is driven to move horizontally by the axial driving member, so that the material plate is pushed to move by the fitting push head 2022 when the extension plate 2021 moves. The axial moving member is pneumatically driven, please refer to Figure 16 , the air supply equipment is used to increase the pressure in the sliding groove, and the extension plate 2021 moves horizontally under the driving of atmospheric pressure.

[0104] Correspondingly, negative pressure is applied to the sliding groove to cause the extension plate 2021 to move in the reverse direction.

[0105] Among them, the arc surface of the fitting push head 2022 cooperates with the stamped material sheet, so that the fitting push head 2022 limits the material sheet when it contacts the material sheet, so that the material sheet will not move toward the sides of the pushing path.

[0106] A notch is formed on the second gear 2018 , and the notch of the second gear 2018 faces the bottom of the connecting seat 205 . The driving assembly is installed at the notch of the second gear 2018 .

[0107] The driving assembly includes motors 2019 fixed on both sides of the base 2026. The output shafts of the two motors 2019 are connected to the third gear 2020 through two first bevel gear sets 2016 respectively.

[0108] In an embodiment of the present invention, the No. 1 bevel gear set 2016 includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed with the output shaft and the transmission shaft of the motor 2019 respectively. When the motor 2019 is working, its output shaft drives the No. 3 gear 2020 to rotate through the No. 2 bevel gear set 2024.

[0109] When in use (working), the plate body 4 is placed on the grid 101, and then the plate body 4 is cut by the cutting gun 302. The cut material plate will be transferred to the lower pressing tool 204 through the cooperation of the rolling turning component and the telescopic part.

[0110] The upper pressing tool 202 is then used to press the sheet material into shape.

[0111] Finally, the stamped sheet is blanked by the blanking assembly.
