Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically a conical press for sealing LNG cylinders on vehicles. Background Technology

[0002] LNG cylinder heads on vehicles typically employ a conical structure, which better withstands internal pressure and enhances cylinder safety. However, manufacturing conical heads is more complex than manufacturing ordinary spherical or elliptical heads. During the pressing process, the metal sheet needs to gradually deform from a flat surface into a complex conical curved surface, placing high demands on the pressure uniformity of the pressing equipment, the rationality of the mold design, and the precise control of the pressing process parameters.

[0003] When existing conical presses are used to press end caps, if the pressure control system malfunctions, such as a pressure sensor failure or a safety valve failure in the hydraulic system, the pressure applied by the press may exceed the mold's tolerance limit. When the pressure is too high, the force on the mold increases sharply, which may cause the mold fixing device to fail, resulting in the mold detaching from the press and creating a risk of it flying out. Existing technologies do not address this issue, therefore, we propose a conical press for LNG cylinder end caps on vehicles. Utility Model Content

[0004] The purpose of this invention is to provide a conical press for sealing LNG cylinders on vehicles, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conical press for sealing LNG cylinders on a vehicle, comprising:

[0006] The base, the column on top of the base, and the top mount on top of the column;

[0007] A protective assembly is placed on one side of the machine base. The protective assembly includes a limiting rod fixed on the machine base, a first rotating shaft rotatably connected to the limiting rod, a protective rail rotatably connected to the first rotating shaft, a limiting seat provided on the side of the machine base away from the limiting rod, a second rotating shaft rotatably connected to the limiting seat, a snap-fit ​​plate rotatably connected to the second rotating shaft, a slot provided on the side of the limiting seat away from the second rotating shaft, and a detector provided on the side of the machine base near the limiting seat.

[0008] A fixing component is placed on the machine base on the side away from the limiting seat. The fixing component includes a limiting ring sleeved on the limiting rod. Extension plates are provided on both sides of the limiting ring. Bolts are threadedly connected between the extension plates and the machine base. Nuts are threadedly connected to the bolts.

[0009] In a preferred embodiment, a clamping assembly is provided on the side of the base near the detector. The clamping assembly includes a third rotating shaft, on which a torsion spring is provided, and a clamping plate is rotatably connected.

[0010] The above technical solution involves using a clamping assembly to clamp the detector and fix it to the base.

[0011] In a preferred embodiment, a fixed seat is provided on the top of the base near the column, and a mold assembly is provided on the top of the fixed seat. The mold assembly consists of a lower mold and an upper mold, and the lower mold is fixedly connected to the fixed seat.

[0012] The above technical solution involves a mold assembly where the upper mold is typically a punch that matches the shape of the inner surface of the desired conical head, and the lower mold is a die that matches the shape of the outer surface of the head.

[0013] In a preferred embodiment, a pressing component is provided at the bottom of the top seat. The pressing component includes a hydraulic cylinder, and a connecting plate is fixedly connected to the output end of the hydraulic cylinder. The upper mold is fixedly connected to the bottom of the connecting plate.

[0014] The above technical solution involves setting up a pressing component to provide power for the pressing process. The piston movement of the hydraulic cylinder generates enormous pressure, which pushes the upper mold downward to press the end cap material.

[0015] In a preferred embodiment, a sleeve is slidably connected to the column, and a connector is fixedly connected between the sleeve and the connecting plate.

[0016] The above technical solution is adopted: by setting up sleeves and connecting parts, stability is maintained during the pressing of the upper mold.

[0017] In a preferred embodiment, a buffer assembly is provided between the top of the base and the bottom of the fixed base. The buffer assembly includes a spring, and the spring has damping inside.

[0018] The above technical solution is adopted: by setting up a buffer component, the impact force generated during pressing is absorbed and buffered to prevent mold breakage.

[0019] In a preferred embodiment, four protective components are provided, and the four protective components are respectively located around the base.

[0020] The above technical solution involves setting up four protective components to protect the press from all sides.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, the protective components prevent the mold from flying out due to excessive pressure and injuring workers. The detector design automatically stops the press when the door is opened. This solves the problem of existing conical presses, which, when pressing heads, may apply pressure exceeding the mold's tolerance if the pressure control system malfunctions (e.g., a faulty pressure sensor or a failed safety valve in the hydraulic system). Excessive pressure causes a sharp increase in force on the mold, potentially overwhelming the mold-fixing device and causing the mold to detach from the press, posing a risk of flying out. Existing technologies have not addressed this issue. The invention uses a buffer component to absorb and cushion the impact force during pressing, preventing mold breakage. Furthermore, the sleeve and connecting parts ensure stability during the pressing process. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1-2 As shown, a conical press for sealing LNG cylinders on a vehicle includes:

[0039] The base 1, the column 9 installed on the top of the base 1, and the top seat 10 installed on the top of the column 9;

[0040] The protective component 2 is placed on one side of the base 1. The protective component 2 includes a limiting rod 21 fixed on the base 1, a first rotating shaft 22 rotatably connected to the limiting rod 21, a protective rail 23 rotatably connected to the first rotating shaft 22, a limiting seat 24 provided on the side of the base 1 away from the limiting rod 21, a second rotating shaft 25 rotatably connected to the limiting seat 24, a snap-fit ​​plate 26 rotatably connected to the second rotating shaft 25, a slot 27 provided on the side of the limiting seat 24 away from the second rotating shaft 25, and a detector 28 provided on the side of the base 1 near the limiting seat 24.

[0041] The fixing component 4 is placed on the machine base 1 on the side away from the limiting seat 24. The fixing component 4 includes a limiting ring 41 sleeved on the limiting rod 21. Extension plates 42 are provided on both sides of the limiting ring 41. Bolts 43 are threadedly connected between the extension plates 42 and the machine base 1. Nuts 44 are threadedly connected to the bolts 43.

[0042] Specifically, when the pressure is too high, the force on the mold will increase sharply, which may cause the device that fixes the mold to be unable to withstand it, thus causing the mold to detach from the press and create a danger of flying out. The protective component 2 is set to close the protective railing 23 through the first rotating shaft 22, and then the second rotating shaft 25 will lock the locking plate 26 into the locking groove 27 to position the protective railing 23, thereby preventing the mold from flying out. When it is necessary to open the protective railing 23 to remove the end cap, the detector 28 will be sensed, thereby stopping the press and preventing injury to the staff.

[0043] Furthermore, such as Figure 1 machine Figure 3As shown: A pressing assembly 8 is provided at the bottom of the top seat 10. The pressing assembly 8 includes a hydraulic cylinder 81. The output end of the hydraulic cylinder 81 is fixedly connected to a connecting plate 82. The upper mold 62 is fixedly connected to the bottom of the connecting plate 82. A fixed seat 5 is provided on the top of the machine base 1 near the column 9. A mold assembly 6 is provided on the top of the fixed seat 5. The mold assembly 6 consists of a lower mold 61 and an upper mold 62. The lower mold 61 is fixedly connected in the fixed seat 5. The upper mold is usually a punch that matches the shape of the inner surface of the required conical head. The lower mold is a die that matches the shape of the outer surface of the head. By setting the pressing assembly 8, power is provided for the pressing process. The piston movement of the hydraulic cylinder 81 generates huge pressure, which pushes the upper mold downward to achieve the pressing of the head material.

[0044] The above solutions also have the problem that excessive downward pressure can easily lead to mold breakage, such as... Figure 3 As shown: A buffer assembly 7 is provided between the top of the base 1 and the bottom of the fixed base 5. The buffer assembly 7 includes a spring 71 and a damper 72 is provided inside the spring 71. By setting the buffer assembly 7, the impact force generated during pressing is absorbed and buffered to prevent the mold from breaking.

[0045] The above solution also has the problem that detector 28 cannot be fixed on base 1, such as... Figure 2 As shown: A clamping assembly 3 is provided on the side of the base 1 near the detector 28. The clamping assembly 3 includes a third rotating shaft 31, a torsion spring 32 is provided on the third rotating shaft 31, and a clamping plate 33 is rotatably connected to the torsion spring 32. By setting the clamping assembly 3, the detector 28 is clamped and fixed on the base 1.

[0046] Furthermore, such as Figure 1 As shown: A sleeve 83 is slidably connected to the column 9, and a connector 84 is fixedly connected between the sleeve 83 and the connecting plate 82. By setting the sleeve 83 and the connector 84, stability is maintained during the pressing of the upper mold.

[0047] The working principle of this utility model is as follows: First, the end cap is placed on the lower mold 61. Then, the protective railing 23 is closed by the first rotating shaft 22. Subsequently, the snap-fit ​​plate 26 is snapped into the slot 27 by the second rotating shaft 25 to position the protective railing 23, thereby preventing the mold from flying out due to excessive pressure. The design of the fixing component 4 can fix the limit rod 21 to the machine base 1. Then, the hydraulic cylinder 81 is opened to drive the bottom connecting plate 82 to move downward. The design of the sleeve 83 and the connecting piece 84 can keep the upper mold 62 stable during the pressing process. The upper mold 62 and the lower mold 61 gradually close, applying uniform pressure to the metal plate and causing the plate to undergo plastic deformation. During the pressing process, the design of the spring 71 and the damper 72 can absorb the impact force on the mold and prevent the mold from breaking due to excessive pressure. After the end cap is pressed, the protective railing 23 is opened, and the detector 28 will be sensed, thereby stopping the press and preventing injury to the workers.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
