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 refer to closed equipment that contains gas or liquid and bears a certain pressure. In order to more effectively implement scientific management and safety inspection, my country's "Safety Supervision Regulations for Pressure Vessels" divides pressure vessels into three categories based on working pressure, medium hazard and its role in production.

[0003] A pressure vessel is a closed 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. 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.

[0004] The top of the pressure vessel is usually circular, which can prevent the top from deforming easily when the internal pressure of the container increases. The top of the container is usually obtained by cutting and stamping steel.

[0005] 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, and the steps are relatively complicated and the integration is low.

[0006] The reason why the existing equipment does not combine the cutting equipment and the stamping equipment is that the 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.

[0007] Of course, this can be achieved through the coordinated work of robotic arms and cylinders, but the cost of purchasing, debugging, using and maintaining this method is too high, and the cost difference is too large compared to step-by-step processing. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a plasma cutting machine for blanking steel plates of pressure vessels, which solves the problem that it is difficult to transport the cut plates to stamping equipment.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: a pressure vessel steel plate blanking plasma cutting machine, comprising a machine platform and a bearing frame slidably mounted on the machine platform, a grid is fixed on the machine platform, and also comprises slide seats slidably mounted on both sides of the machine platform, the two slide seats are connected by a rectangular rod, a slide platform is slidably mounted on the rectangular rod, a lifting plate is slidably mounted on the slide platform toward one side of the bearing frame, and a cutting gun is fixed on the lifting plate; A lower pressing tool slidably mounted on a carrier frame, with two guide rods fixed on both sides of the lower pressing tool. An upper pressing tool cooperating with the lower pressing tool is slidably mounted on the guide rods. Axial holes are provided at the tops of the four guide rods, and a follower frame fixed to the slide is slidably mounted in the axial holes. A feeding mechanism is mounted on the side of the lower pressing tool facing the slide, and a blanking assembly is mounted on the side of the lower pressing tool away from the slide. An activity groove opened on the lower pressing tool, and an ejecting assembly is mounted inside the lower pressing tool.

[0010] Further, the ejecting assembly includes a lifting plate slidably mounted in the activity groove, and an elastic piece is fixed to the bottom of the lifting plate. Among them, the lower pressing tool includes a base, a concave surface is provided on the base, and the top of the lifting plate has the same shape as the bottom of the concave surface of the lower pressing tool.

[0011] Further, the feeding mechanism includes a connecting seat slidably mounted on the carrier frame and fixed to the lower pressing tool. A sleeve plate is mounted on the connecting seat through a rolling rotation assembly. A sliding plate is slidably mounted inside the sleeve plate. The sleeve plate and the sliding plate are connected by a telescopic member, and the telescopic member is connected to the rolling rotation assembly. An electromagnet is rotatably mounted at the end of the sliding plate. Among them, the electromagnet includes an adsorption part and a connecting part. The connecting part of the electromagnet is rotatably connected to the sliding plate, and a stroke limiting member is mounted between the connecting part of the electromagnet and the sliding plate.

[0012] Further, the telescopic member includes a lead screw rotatably mounted inside the sleeve plate, and the lead screw is in threaded cooperation with an internal threaded hole opened at the end of the sliding plate. A transmission shaft is mounted on one side of the sleeve plate and passes through and is rotatably connected to the sleeve plate. The transmission shaft is connected to the lead screw through a second bevel gear set, and the transmission shaft is connected to the rolling rotation assembly.

[0013] Further, the rolling rotation assembly includes a U-shaped base, the base is horizontally slidably mounted on the connecting seat, a rack part integrally formed with the connecting seat is provided on the connecting seat, and the rack part is engaged with a third gear rotatably mounted on the base. A second gear is fixed to one side of the base, and a first gear meshing with the second gear is coaxially fixed on the transmission shaft. The third gear is coaxially fixed to the end of the sleeve plate away from the sliding plate. Drive assemblies are mounted on both sides of the base.

[0014] Further, the stroke limiting member includes a limiting groove opened on the opposite side of the connecting part of the electromagnet, and limiting blocks slidably mounted in the limiting groove are fixed on both sides of the sliding plate.

[0015] Further, the blanking component includes a blanking member fixed on the bearing frame. The blanking member is arranged in an isosceles triangle shape, and a V-shaped groove is opened at the top of the blanking member. The blanking member is located on the side of the lower pressing tool away from the sliding table. A blanking guide block fixed to the lower pressing tool is installed between the lower pressing tool and the blanking member. A pushing member cooperating with the blanking guide block and the blanking member is installed on the connecting seat.

[0016] Further, the pushing member includes a sliding groove opened on the side of the connecting seat facing the lower pressing tool. An extension plate is slidably installed in the sliding groove. A fitting push head is fixed to the end of the extension plate, and an arc surface is arranged at the end of the fitting push head.

[0017] Further, a notch is opened on the second gear, and the notch of the second gear faces the bottom of the connecting seat. The driving component is installed at the notch position of the second gear.

[0018] Further, the driving component includes motors fixed on both sides of the base table. The output shafts of the two motors are respectively connected to the third gear through two first bevel gear sets.

[0019] The present invention has the following beneficial effects: First, in this plasma cutting machine for blanking pressure vessel steel plates, the stamping-related structures are driven by the follower frame to move along with the sliding table and the cutting gun, so that the positions between the stamping-related structures, the sliding table and the cutting gun always remain unchanged.

[0020] Second, in this plasma cutting machine for blanking pressure vessel steel plates, the coordinated operation of the rolling rotation component and the telescopic member realizes the directional transfer work in a relatively high space, that is, the transfer from point A to point B. Among them, the positions of point A and point B always change along with the movement of the sliding table and the cutting gun, but the path from point A to point B remains unchanged. Thus, any blanking plate cut by the cutting gun can be rotated onto the lower pressing tool and completed the stamping through the downward pressure of the follower frame.

[0021] Third, in this plasma cutting machine for blanking pressure vessel steel plates, through the cooperation of the blanking component and the ejecting component, the blanking plate (i.e., the container top cover) stamped out is stably blanked from both sides of the bearing frame to solve the problem of uncertain blanking position caused by the continuous change of the position of the blanking guide block.

[0022] Fourth, this plasma cutting machine for blanking pressure vessel steel plates has a relatively high degree of automation, a relatively simple structure, and low production costs.

[0023] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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.

[0028] According to the following Figures 1 - 16 The present invention describes a pressure vessel steel plate blanking plasma cutting machine provided in an embodiment of the present invention.

[0029] See also Figures 1 - 16 An embodiment of the present invention provides a pressure vessel steel plate blanking plasma cutting machine, including a machine platform 1 and a supporting frame 2 slidably mounted on the machine platform 1, a grid 101 is fixed on the machine platform 1, and also includes slides 301 slidably mounted on both sides of the machine platform 1, the two slides 301 are connected by a rectangular rod, a slide 3 is slidably mounted on the rectangular rod, a lifting plate 303 is slidably mounted on the slide 3 toward one side of the supporting frame 2, and a cutting gun 302 is fixed on the lifting plate 303.

[0030] like Figure 1 , Figures 4 - 7As shown in the figure, a lower pressing tool 204 is also provided. The lower pressing tool 204 is slidably mounted on the carrier 2. Two guide rods 203 are fixed on both sides of the lower pressing tool 204. An upper pressing tool 202 cooperating with the lower pressing tool 204 is slidably mounted on the guide rods 203. Axial holes 2015 are formed at the tops of the four guide rods 203. A follower frame 201 fixed to the slide 3 is slidably mounted in the axial holes 2015. A feeding mechanism is mounted on one side of the lower pressing tool 204 facing the slide 3, and a blanking assembly is mounted on the side of the lower pressing tool 204 away from the slide 3.

[0031] An activity groove 2014 is also formed in the lower pressing tool 204. A top-out assembly is mounted in the lower pressing tool 204 for ejecting the workpiece after stamping.

[0032] In the embodiment of the present invention, the two sliding seats 301 can slide along the length direction of the machine table 1, and can drive the rectangular rod to slide vertically between the two sliding seats 301. The slide 3 can slide axially on the rectangular rod. The lifting plate 303 can slide vertically on the slide 3, and at the same time drive the cutting gun 302 to slide vertically. Among them, the vertical sliding of the lifting plate 303 and the axial sliding of the slide 3 along the rectangular rod are both driven by the driving member 304, so as to realize the left-right, up-down, and front-back movements of the cutting gun 302 on the machine table 1.

[0033] When the slide 3 moves horizontally, the follower frame 201 also drives the guide rods 203, the lower pressing tool 204, and the upper pressing tool 202 to move horizontally synchronously. When the slide 3 moves back and forth, that is, when it moves along the length direction of the machine table 1, the follower frame 201 drives the guide rods 203, the lower pressing tool 204, and the upper pressing tool 202 to move synchronously, so as to ensure that the upper pressing tool 202 and the lower pressing tool 204 always follow the movement of the slide 3 when the slide 3 moves. When the rectangular rod is driven to rise or fall by the two sliding seats 301, the follower frame 201 will be driven to rise and fall synchronously. Since the follower frame 201 is slidably connected to the guide rods 203, the guide rods 203 will not be driven to rise.

[0034] When the present invention is in processing, the sheet body 4 is placed on the grille 101 on the machine table 1, and the position of the sheet body 4 is corrected so that the length surface of the sheet body 4 is parallel to the length surface of the machine table 1.

[0035] Subsequently, drive the cutting torch 302 to work, and cooperate with the forward and backward and left and right movements of the cutting torch 302 to cut out a plurality of circular plate parts at equal intervals on the plate body 4. Herein, the circular plate parts of the present invention are named stock plates. The cut stock plates will be transported to the lower press tool 204 through the feeding mechanism, and then pressed down by the pressing device. The pressing device can be a cylinder or a hydraulic cylinder, etc., which is not specifically limited in the present invention. And since the plates stamped in the present invention are relatively thin, the force for driving the follower frame 201 to press down is relatively low, so the selectable devices are also relatively extensive. Drive the upper press tool 202 to descend, so that through the descent of the upper press tool 202, the convex surface at the top of the upper press tool 202 is matched with the concave surface at the top of the lower press tool 204, and then cooperate with the punching force to stamp the stock plate into the specified shape.

[0036] Among them, when the upper press tool 202 descends to punch the stock plate, the ejection assembly is also triggered to work. When the upper press tool 202 rises, the stock plate that has been stamped and embedded in the concave surface of the lower press tool 204 is ejected through the work of the ejection assembly, so as to be pushed out and discharged through the blanking assembly, facilitating subsequent punching again.

[0037] Please refer to Figure 7 、 Figure 8 The ejection assembly includes a lifting plate 2012 slidably installed in the movable groove 2014, and an elastic piece 2013 is fixed to the bottom of the lifting plate 2012.

[0038] Among them, the lower press tool 204 includes a base, and a concave surface is provided on the base. The top of the lifting plate 2012 has the same shape as the bottom of the concave surface of the lower press tool 204.

[0039] In the embodiment of the present invention, when the upper press tool 202 presses down, while deforming the stock plate, a downward pressure is applied to the lifting plate 2012, so that the lifting plate 2012 descends vertically, and when descending, the elastic piece 2013 is driven to deform from a U shape to a straight shape. During this process, the elastic piece 2013 stores elasticity. When the upper press tool 202 rises after the stock plate is punched, the elastic potential energy of the elastic piece 2013 is released to drive the lifting plate 2012 to rise, so as to lift the stamped stock plate through the rise of the lifting plate 2012.

[0040] Among them, since the top of the lifting plate 2012 has the same shape as the bottom of the concave surface of the lower press tool 204, that is, the top surface of the lifting plate 2012 is an arc, when the lifting plate 2012 lifts the stamped stock plate, it will not fall on the lifting plate 2012.

[0041] The feeding mechanism includes a connecting seat 205 that is slidably installed on the carrier 2 and fixed to the lower press tool 204.

[0042] A sleeve plate 208 is installed on the connecting base 205 through a rolling and turning component. A sliding plate 209 is slidably installed in the sleeve plate 208. The sleeve plate 208 and the sliding plate 209 are connected by a telescopic member, and the telescopic member is connected to the rolling and turning component.

[0043] An electromagnet 2010 is rotatably installed at the end of the sliding plate 209.

[0044] Among them, the electromagnet 2010 includes an adsorption part and a connection part. The connection part of the electromagnet 2010 is rotatably connected to the sliding plate 209, and a stroke limiting member is installed between the connection part of the electromagnet 2010 and the sliding plate 209.

[0045] In the embodiment of the present invention, the sheet body 4 is cut by the cutting torch 302. At the starting point and the ending point of the cutting, the electromagnet 2010 is located at the center point of the cut sheet. After the sheet is separated from the sheet body 4, it is adsorbed by the electromagnet 2010.

[0046] While driving the sleeve plate 208 to flip towards the lower press tool 204 and move towards the lower press tool 204 through the rolling and turning component, the telescopic member is also driven to work by the rolling and turning component during this process. The sliding plate 209 is driven by the telescopic member 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 sheet adsorbed by the electromagnet 2010 is coaxial with the concave surface of the lower press tool 204. By cutting off the adsorption between the electromagnet 2010 and the sheet, the sheet falls onto the concave surface of the lower press tool 204.

[0047] The technical effect achieved is that due to the limitation of the movement space, if the telescopic setting is not performed between the sliding plate 209 and the sleeve plate 208, it will cause the problem of interference between the sleeve plate 208 and the sliding plate 209 and other components during flipping. The main reason is that the rotation radius of the sliding plate 209 and the sleeve plate 208 is relatively large during rotation. Reducing the lengths of the sliding plate 209 and the sleeve plate 208 will result in a relatively large distance between the electromagnet 2010 and the sheet, and the sheet cannot be effectively adsorbed onto the electromagnet 2010. Moreover, due to the reduction of the lengths of the sliding plate 209 and the sleeve plate 208, when the sliding plate 209 and the sleeve plate 208 flip to the end of the stroke, the positions of the electromagnet 2010 and the sheet cannot be in a position coaxial with the concave surface of the lower press tool 204.

[0048] The solution of the present application is that when the sliding plate 209 and the sleeve plate 208 flip, the sliding plate 209 is retracted into the sleeve plate 208 to reduce the rotation radius and avoid the problem of interference with other components. However, since the sliding plate 209 is retracted into the sleeve plate 208, in essence, the lengths of the sliding plate 209 and the sleeve plate 208 are still reduced. When the sleeve plate 208 and the sliding plate 209 flip to the end of the stroke, the electromagnet 2010 and the sheet still cannot be coaxial with the concave surface of the lower press tool 204. Therefore, the sleeve plate 208 in the present invention also moves towards the lower press tool 204 when flipping to make up for the problem of insufficient length.

[0049] The telescopic member includes a lead screw 2025 rotatably installed in the sleeve plate 208, and the lead screw 2025 is in threaded engagement with an internal threaded hole 502 opened at the end of the sliding plate 209.

[0050] One side of the sleeve plate 208 is provided with a transmission shaft that penetrates and is rotatably connected to the sleeve plate 208. The transmission shaft is connected to the lead screw 2025 through a second bevel gear set 2024, and the transmission shaft is connected to a rolling rotation adjustment assembly.

[0051] In the embodiment of the present invention, when the sleeve plate 208 is flipped, the transmission shaft is driven to rotate by the rolling rotation adjustment assembly. When the transmission shaft rotates, the sliding plate 209 is driven to move towards the inside of the sleeve plate 208 through the threaded engagement with the internal threaded hole 502. When the sliding plate 209 moves, the electromagnet 2010 is driven to move synchronously.

[0052] The rolling rotation adjustment assembly includes a base 2026 arranged in a U shape. The base 2026 is horizontally slidably installed 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 a third gear 2020 rotatably installed on the base 2026.

[0053] One side of the base 2026 is fixed with a second gear 2018, and a first gear 2017 engaged with the second gear 2018 is coaxially fixed on the transmission shaft.

[0054] The third gear 2020 is coaxially fixed to the end of the sleeve plate 208 away from the sliding plate 209.

[0055] Drive assemblies are installed on both sides of the base 2026.

[0056] In the embodiment of the present invention, the third gear 2020 is driven to rotate by the drive assembly.

[0057] When the third gear 2020 rotates, through the engagement with the rack portion 2023, the third gear 2020 moves downward towards the lower pressing tool 204 while rotating itself. This rolling forward drives the sleeve plate 208 to move towards the lower pressing tool 204 while flipping.

[0058] Among them, when the sleeve plate 208 flips, it drives the transmission shaft and the first gear 2017 to perform a circumferential movement with the axis of the third gear 2020 as the center. During this process, the first gear 2017 and the transmission shaft rotate through the engagement of the first gear 2017 and the second gear 2018. When the first gear 2017 rotates, the lead screw 2025 is driven to rotate through the second bevel gear set 2024, and the rotation of the lead screw 2025 corresponds to the movement of the sliding plate 209 towards the inside of the sleeve plate 208.

[0059] The realized motion state is that while the sleeve plate 208 flips towards the lower press tool 204 with the third gear 2020 as the axis, it moves horizontally towards the lower press tool 204, and at the same time drives the sliding plate 209 to move towards the inside of the sleeve plate 208.

[0060] Through this one motion state, the motion space required for transfer can be greatly reduced.

[0061] It should also be noted that the base 2026 includes two bearing 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.

[0062] The stroke limiting member includes a limiting groove 5 opened on the opposite side of the connecting portion of the electromagnet 2010. Limiting blocks 501 are fixed on both sides of the sliding plate 209 and are slidably installed in the limiting groove 5.

[0063] In the embodiment of the present invention, when the sleeve plate 208 and the sliding plate 209 are in the flipped and erected state, subsequent rotations will flip under the drive of gravity. Please refer to Figure 14 .

[0064] Through the cooperation of the limiting groove 5 and the limiting blocks 501, the electromagnet 2010 can be quickly stabilized after flipping, reducing shaking.

[0065] As an optional embodiment of the present invention, second electromagnets are installed at both the stroke starting end and the stroke ending end of the limiting groove 5. When the limiting block 501 is at the stroke starting end or the stroke ending end, the limiting block 501 is adsorbed by the second electromagnet to achieve a positioning effect and avoid the generation of shaking.

[0066] The blanking assembly includes a blanking member 206 fixed on the bearing frame 2. The blanking member 206 is arranged in an isosceles triangle shape, and a V-shaped groove 2011 is opened at the top of the blanking member 206. The blanking member 206 is located on the side of the lower press tool 204 away from the sliding table 3.

[0067] A blanking guide block 207 fixed to the lower press tool 204 is installed between the lower press tool 204 and the blanking member 206.

[0068] A pushing member cooperating with the blanking guide block 207 and the blanking member 206 is installed on the connecting seat 205.

[0069] In the embodiment of the present invention, when the base 2026 moves towards the lower press tool 204, it drives the pushing member to work, so as to push the stamped sheet by the pushing member. When the stamped sheet moves, it is limited by the blanking guide block 207 so that it will not fall during the movement. Finally, the stamped sheet enters the V-shaped groove 2011 of the blanking member 206.

[0070] The stock plate located within the V-shaped groove 2011 will move towards one side or the other under the action of the inclined surface at the top of the blanking part 206. Collection boxes can be fixed on both sides of the carrier 2, and the stock plates are collected through the collection boxes.

[0071] Among them, the V-shaped groove 2011 can provide a certain limit and guidance for the stock plate on the blanking part 206, so that the stock plate will not have too large a position deviation when moving into the collection box.

[0072] The pushing member includes a sliding groove opened on the side of the connecting seat 205 facing the pressing tool 204. An extension plate 2021 is slidably installed in the sliding groove. A fitting push head 2022 is fixed at the end of the extension plate 2021, and an arc surface is provided at the end of the fitting push head 2022.

[0073] In the embodiment of the present invention, the extension plate 2021 is axially driven by an axial driving member to move horizontally, so as to push the stock plate to move through the fitting push head 2022 when the extension plate 2021 moves. The axial moving member is pneumatically driven. Please refer to Figure 16 , pressurize the sliding groove through a gas supply device, and under the drive of atmospheric pressure, the extension plate 2021 moves horizontally.

[0074] Correspondingly, applying negative pressure to the sliding groove causes the extension plate 2021 to move in the reverse direction.

[0075] Among them, the arc surface of the fitting push head 2022 cooperates with the stamped stock plate, so that the fitting push head 2022 limits the stock plate when contacting the stock plate, and the stock plate will not move towards both sides of the pushing path.

[0076] A notch is opened on the second gear 2018, the notch of the second gear 2018 faces the bottom of the connecting seat 205, and the drive assembly is installed at the notch position of the second gear 2018.

[0077] The drive assembly includes motors 2019 fixed on both sides of the base 2026. The output shafts of the two motors 2019 are respectively connected to the third gear 2020 through two first bevel gear sets 2016.

[0078] In the embodiment of the present invention, the first bevel gear set 2016 includes two meshing bevel gears. The two bevel gears are coaxially fixed to the output shaft of the motor 2019 and the transmission shaft respectively. When the motor 2019 works, its output shaft drives the third gear 2020 to rotate through the second bevel gear set 2024.

[0079] During use (when working), place the sheet body 4 on the grille 101, and then cut the sheet body 4 with the cutting gun 302. The cut stock plates will be transferred to the pressing tool 204 through the cooperation of the rolling and turning component and the telescopic member.

[0080] Then, the material plate is stamped and formed by the downward pressing of the upper press tool 202.

[0081] Finally, the stamped material plate is unloaded through the unloading component.
