Description

Technical Field

[0001] This utility model belongs to the field of pressure vessel processing technology, and in particular relates to a CNC shearing equipment for pressure vessel processing. Background Technology

[0002] A pressure vessel is a sealed container capable of withstanding pressure. Pressure vessels have a wide range of applications, playing an important role in many sectors, including industry, civil use, military, and scientific research. The production process of pressure vessels requires the cutting and trimming of raw material plates to obtain the required specifications.

[0003] An existing patent (application number: CN202421857623.6) discloses a CNC following shearing mechanism, relating to the field of CNC shearing equipment technology. It includes a bed, on which a shear assembly is mounted. The shear assembly mainly consists of a gantry frame, a hydraulic cylinder, and an upper tool holder. Two gantry frames are mounted on the bed, their upper surfaces connected by two bases. A hydraulic cylinder is mounted on the upper surface of each base, with its extension end penetrating the base and connecting to the upper tool holder. An elastic pressure assembly is mounted at one end of the upper tool holder, and a lower tool holder is mounted below it. The mechanism also includes a tool follower assembly and a clearance assembly. Transmission mechanisms are mounted at both ends of the gantry frames. This application, through the tool follower assembly, enables the shear assembly to move with the sheet metal, avoiding workpiece stops and frequent belt starts and stops, significantly improving production efficiency. Furthermore, the clearance assembly allows the belt to pass under the shear assembly, thus avoiding it. Finally, the transmission assembly reduces energy consumption.

[0004] The aforementioned document describes a shearing device that can reduce energy consumption. However, the device lacks a plate positioning function during use, which can lead to the need for manual adjustment of the plate cutting position when cutting different specifications of plates. This makes it difficult to maintain the cutting accuracy of the plates. Therefore, a CNC shearing device for pressure vessel processing is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a CNC shearing equipment for pressure vessel processing. This equipment features adjustable limit spacing based on the required shearing specifications of the sheet material, enabling precise positioning and quantitative conveying of the sheet material to prevent deviation. This improves the shearing accuracy of the sheet material and ensures the forming quality of the pressure vessel. It solves the problem mentioned in the aforementioned comparative documents that the shearing equipment lacks sheet material positioning during use, which necessitates manual adjustment of the shearing position when shearing different specifications, thus making it difficult to maintain shearing accuracy.

[0006] To achieve the above objectives, this application provides the following technical solution: a CNC shearing machine for pressure vessel processing, comprising a machine base, a hydraulic shearing body disposed on the top of the machine base, an upper blade holder disposed inside the hydraulic shearing body, a lower blade holder disposed inside the machine base, a first driving device disposed on one side of the machine base, a support device threadedly connected to the output end of the first driving device, a second driving mechanism fixedly connected inside the support device, a rotary positioning component meshing on one side of the second driving mechanism, a positioning groove opened on the top of the machine base, a displacement device disposed on the inner wall of the machine base, and a limit mechanism threadedly connected to the output end of the displacement device.

[0007] The above scheme connects the support device to the rotary positioning component and the first drive device, respectively. The rotary positioning component is driven to rotate by the second drive mechanism to push the sheet metal for automatic feeding. The support device is driven to move in opposite directions by the first drive device, so that the rotary positioning component at the top moves closer or further away to adjust the positioning distance between them. This allows for precise positioning and conveying of sheet metal of different specifications. In addition, the displacement device drives the limiting mechanism to move laterally, which facilitates the adjustment of the limiting distance according to the required cutting specifications of the sheet metal. This achieves a precise positioning and conveying effect to prevent the sheet metal from deviating, improves the cutting accuracy of the sheet metal, and ensures the forming quality of the pressure vessel.

[0008] Furthermore, the first driving device includes a first driving motor, a pulley is fixedly installed at the output end of the first driving motor, a bidirectional screw is fixedly installed at the output end of the pulley, and the bidirectional screw passes through the interior of the support device and is threadedly connected to it.

[0009] Through the above scheme, the first drive motor and the pulley work together to provide rotational driving force for the bidirectional screw, thereby indirectly driving the support device to move the rotary positioning component.

[0010] Furthermore, the support device includes a support plate, the bottom of which is fixedly connected to a limiting slider, which is slidably connected to the inside of the machine tool.

[0011] The above scheme uses a bidirectional screw to drive the support plate to move laterally along the inside of the machine tool, while simultaneously driving the limit slider to slide synchronously. This allows for flexible adjustment of the driving force at the bottom of the rotary positioning component.

[0012] Furthermore, the rotary positioning assembly includes a rotary positioning wheel, a first gear is provided at the bottom of the rotary positioning wheel, a transmission gear is meshed on one side of the first gear, and the number of the first gear and the transmission gear is set to several.

[0013] The above scheme involves activating the second drive mechanism to drive the first gear to rotate, which in turn drives the transmission gear to the next set of first gears, thereby driving the rotating positioning wheel to rotate. By adjusting the distance between the rotating positioning wheels through the displacement of the support plate driven by the bidirectional screw, the side edge of the plate can be positioned and automatically fed to achieve a precise positioning, feeding, and shearing effect.

[0014] Furthermore, the second drive mechanism includes a second drive motor, and a bevel gear is fixedly mounted on the output end of the second drive motor, the bevel gear meshing with the first gear.

[0015] The above scheme uses a second drive motor to drive a bevel gear to rotate, which in turn drives the first gear to rotate a certain angle at a time. This, in turn, drives the rotating positioning wheel to rotate a certain angle at a time, causing the sheet metal to move a certain displacement and automatically feed towards the hydraulic shearing machine body.

[0016] Furthermore, the displacement device includes a displacement motor, the output end of which is fixedly mounted with a threaded shaft, and the output end of the threaded shaft is threadedly connected to a displacement slider.

[0017] The above scheme uses a displacement motor to drive a threaded shaft to move a displacement slider along the inner wall of the machine tool, thereby causing the limiting mechanism to move laterally and adjusting the distance between the limiting mechanism and the upper blade holder shearing position to change the limiting position on the end face of the sheet metal.

[0018] Furthermore, the limiting mechanism includes a limiting baffle, a limiting motor is fixedly installed on one side of the displacement slider, the output end of the limiting motor is fixedly connected to the limiting baffle, and a guide slider is fixedly connected to one end of the limiting baffle.

[0019] The above scheme uses a limit motor fixed to one side of the displacement slider to drive the limit baffle to rotate to a horizontal position. This allows the sheet material to continue to be sheared after shearing without hindering the discharge. The displacement slider also drives the limit baffle to move laterally, allowing the limit baffle to adjust its position according to the sheet material shearing specifications.

[0020] Furthermore, the number of the rotating positioning wheels is set to several, and the several rotating positioning wheels are symmetrically arranged inside the machine tool.

[0021] The above scheme, through the combined action of multiple sets of rotating positioning wheels, can provide a longer positioning and feeding channel for the sheet material, so that the sheet material can be automatically fed and cut stably and smoothly.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This CNC shearing equipment for pressure vessel processing connects a support device to a rotary positioning component and a first drive device. A second drive mechanism drives the rotary positioning component to rotate, automatically feeding the sheet metal. The first drive device drives the support device to move in opposite directions, causing the top rotary positioning component to move closer or further away to adjust the positioning distance between them. This allows for precise positioning and conveying of sheet metal of different specifications. In addition, a displacement device drives a limiting mechanism to move laterally, facilitating adjustment of the limiting distance according to the required shearing specifications of the sheet metal. This achieves precise positioning and conveying of the sheet metal to prevent deviation, improves the shearing accuracy of the sheet metal, and ensures the forming quality of the pressure vessel.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 2 , Figure 4 and Figure 5 This embodiment of a CNC shearing machine for pressure vessel processing includes a machine base 1, a hydraulic shearing body 2 on the top of the machine base 1, an upper blade holder 3 inside the hydraulic shearing body 2, a lower blade holder 4 inside the machine base 1, a first driving device 5 on one side of the machine base 1, a support device 6 threadedly connected to the output end of the first driving device 5, a second driving mechanism 7 fixedly connected inside the support device 6, a rotary positioning assembly 8 engaged on one side of the second driving mechanism 7, a positioning groove 9 on the top of the machine base 1, a displacement device 10 on the inner wall of the machine base 1, and a limit mechanism 11 threadedly connected to the output end of the displacement device 10. By connecting the support device 6 to the rotary positioning assembly 9, the machine base 1 can achieve the desired shearing effect. The positioning component 8 is connected to the first driving device 5. When the pressure vessel plate needs to be sheared, the second driving mechanism 7 drives the rotary positioning component 8 to rotate, so as to push the plate to automatically feed in a quantitative manner. The first driving device 5 drives the support device 6 to move in opposite directions, so as to drive the top rotary positioning component 8 to move closer or further away at the same time to adjust the positioning distance between them. This allows for precise positioning and conveying of plates of different specifications. In addition, the displacement device 10 drives the limiting mechanism 11 to move laterally, so as to adjust the limiting distance according to the specifications of the plate to be sheared. This achieves the effect of precise positioning and conveying of the plate to prevent deviation, improves the accuracy of shearing the plate, and ensures the forming quality of the pressure vessel.

[0034] Please see Figure 4 , Figure 5 and Figure 6The first driving device 5 includes a first driving motor 501. A pulley 502 is fixedly installed at the output end of the first driving motor 501. A bidirectional screw 503 is fixedly installed at the output end of the pulley 502. The bidirectional screw 503 passes through the interior of the support device 6 and is threadedly connected to it. The support device 6 includes a support plate 601. A limit slider 602 is fixedly connected to the bottom of the support plate 601. The limit slider 602 is slidably connected to the interior of the machine base 1. Through the cooperation of the first driving motor 501 and the pulley 502, a rotational driving force can be provided to the bidirectional screw 503, thereby indirectly driving the support device 6 to move the rotary positioning component 8. The bidirectional screw 503 drives the support plate 601 to move laterally along the interior of the machine base 1, and at the same time drives the limit slider 602 to slide synchronously. This allows for flexible adjustment of the driving force at the bottom of the rotary positioning component 8.

[0035] Please see Figure 5 and Figure 6 The rotary positioning assembly 8 includes a rotary positioning wheel 801, with a first gear 802 at its bottom. A transmission gear 803 meshes with one side of the first gear 802. The number of first gears 802 and transmission gears 803 is set to several. The second drive mechanism 7 includes a second drive motor 701, with a bevel gear 702 fixedly mounted at the output end of the second drive motor 701. The bevel gear 702 meshes with the first gear 802. The second drive motor 701 drives the bevel gear 702 to rotate, thereby driving the first gear 802 to rotate a certain angle at a time. This, in conjunction with the transmission gear 803, transmits the material to the next set of first gears 802, thereby driving the rotary positioning wheel 801 to rotate. After adjusting the distance between the rotary positioning wheels 801 by driving the support plate 601 to move via the bidirectional screw 503, the side edge of the sheet material can be positioned and automatically fed to achieve a precise positioning, feeding, and shearing effect.

[0036] Please see Figure 4 and Figure 7The displacement device 10 includes a displacement motor 1011, with a threaded shaft 1012 fixedly mounted on the output end of the displacement motor 1011. A displacement slider 1013 is threadedly connected to the output end of the threaded shaft 1012. The limiting mechanism 11 includes a limiting baffle 1101, with a limiting motor 1102 fixedly mounted on one side of the displacement slider 1013. The output end of the limiting motor 1102 is fixedly connected to the limiting baffle 1101, and a guide slider 1103 is fixedly connected to one end of the limiting baffle 1101. The displacement motor 1011 drives the threaded shaft 1012 to rotate, thereby driving the displacement slider 1013. 3. Slide along the inner wall of the machine base 1 to drive the limiting mechanism 11 to move laterally, and adjust the distance between the cutting position of the upper blade holder 3 to change the limiting position of the end face of the plate. The limiting motor 1102 is fixed to one side of the displacement slider 1013 so that the limiting baffle 1101 can be rotated to a horizontal position by the limiting motor 1102. After the plate is cut, the plate can continue to move forward for cutting without hindering the discharge. It also works with the displacement slider 1013 to drive the limiting baffle 1101 to move laterally so that the limiting baffle 1101 can adjust the limiting position according to the cutting specifications of the plate.

[0037] In this embodiment, a CNC shearing machine for pressure vessel processing provides rotational driving force to a bidirectional screw 503 through the cooperation of a first drive motor 501 and a pulley 502. The bidirectional screw 503 drives a support plate 601 to move laterally along the interior of the machine base 1, simultaneously causing the limit slider 602 to slide synchronously. After adjusting the distance between the rotating positioning wheels 801 by displacing the support plate 601 driven by the bidirectional screw 503, the second drive motor 701 drives the bevel gear 702 to rotate. This drives the first gear 802 to rotate a certain angle in a single operation, which in turn drives the rotating positioning wheel 801 to rotate a certain angle in a single operation, causing the sheet metal to move a certain displacement and automatically feed towards the hydraulic shearing machine body 2. The displacement motor 1011 drives the threaded shaft 1012 to rotate, thereby driving the displacement slider 1013 to slide along the inner wall of the machine base 1. This causes the limiting mechanism 11 to move laterally and adjust the distance between the limiting mechanism 11 and the upper blade holder 3 to change the limiting position on the end face of the sheet metal. The limiting motor 1102 is fixed to one side of the displacement slider 1013, and the limiting motor 1102 drives the limiting baffle 1101 to rotate to a horizontal position. This allows the sheet metal to continue to move forward after shearing without hindering the discharge. In conjunction with the displacement slider 1013, the limiting baffle 1101 is driven to move laterally, so that the limiting baffle 1101 can adjust the limiting position according to the shearing specifications of the sheet metal.

[0038] The working principle of the above embodiments is as follows:

[0039] When in use, the second drive motor 701 is started to drive the bevel gear 702 to rotate, which in turn drives the first gear 802 to rotate. Then, through the transmission gear 803, the adjacent first gears 802 are indirectly driven to rotate, so that multiple sets of rotating positioning wheels 801 rotate synchronously, causing the plate material clamped on their inner side to automatically move to the cutting position of the hydraulic shearing machine body 2. The first drive motor 501 is started to drive the pulley 502 to rotate, which drives the bidirectional screw 503 to rotate, which drives the support plate 601 to move laterally. The limit slider 602 moves synchronously to limit the movement, so that the rotating positioning wheel 801 can follow the movement of a certain distance to accurately position the edge of the plate material of different specifications. At the same time, the limit motor 1102 drives the limit baffle 1101 to rotate from the vertical state to the horizontal state to release the restriction on the plate material. The displacement motor 1011 drives the threaded shaft 1012 to rotate, which drives the displacement slider 1013 to drive the limit baffle 1101 to move laterally, so as to adjust the limit distance with the cutting position according to the cutting specifications of the plate material.
