Description

Technical Field

[0001] This utility model relates to the field of hole-opening equipment technology, and in particular to a container hole-opening device. Background Technology

[0002] Currently, in the field of metal container manufacturing, such as the production of double-walled oil storage tanks, cold trap cylinders, water bath sterilizer cylinders, and biological tanks, it is often necessary to perform circular opening operations on the surface of the cylinder. Currently, the mainstream opening methods include purely manual cutting and some specialized semi-automatic opening fixtures.

[0003] For example, Chinese utility model patent CN110216350A discloses a "tooling and process for opening holes in double-layer oil storage steel tanks". This tooling uses a support, a rotating body, and an elastic telescopic mechanism to drive a flame cutting torch to rotate around a center of rotation, thereby achieving circular cutting. Compared with purely manual cutting, this technical solution improves the roundness and edge smoothness of the opening to a certain extent, effectively solving the problem of uneven edges caused by shaking during hand-held cutting.

[0004] However, its flame cutting torch is set perpendicular to the workpiece surface, and can only complete straight hole cutting. For holes that need to be welded to pipes, welding bevels usually need to be pre-machined. This fixture cannot achieve one-time bevel cutting, and additional beveling processing is still required, which is inefficient.

[0005] Furthermore, its centering and positioning process is cumbersome: the fixture relies on a "positioning rod" pressing against the cylinder wall and a "aligning pin" aligning with the "correction generatrix" for positioning. This process requires precise manual adjustment, demands high operator skills, and its positioning efficiency and accuracy are difficult to guarantee when used on workpieces with different curvatures or positions. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a container opening device that can cut bevels and position efficiently.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a container opening device, including a support, a rotating body rotatably mounted on the support, and a driving mechanism for driving the rotating body to rotate. The rotating body is provided with a cutting mounting seat, which is configured to fix the cutting mechanism at an inclined angle relative to the axis of rotation of the rotating body. The support is provided with a light alignment mechanism on one side of the cutting mounting seat. The light emitted by the light alignment mechanism is used to indicate the center of the hole to be opened. The cutting mechanism is inclined, which can directly form the required welding bevel while cutting the circular hole, eliminating the need for a separate beveling process, and significantly improving efficiency and quality. The light alignment mechanism can quickly, intuitively, and accurately align the rotation center of the device with the center of the hole to be opened, greatly simplifying the operation process, reducing the dependence on the operator's skills, and improving the accuracy of the opening position.

[0008] Furthermore, the tilt angle ranges from 30° to 60°, which is the optimal range for forming a standard weld bevel, ensuring the compatibility of the bevel with the subsequent connecting pipeline, thereby guaranteeing the strength and sealing of the welded structure.

[0009] Furthermore, the cutting mounting base is equipped with a clamp assembly for fixing the cutting mechanism. The clamp assembly provides a fast, reliable clamping method applicable to cutting mechanisms of different pipe diameters, enhancing the convenience and versatility of the equipment.

[0010] Furthermore, the cutting mounting base can be slidably mounted on the rotating body along a straight line. By adjusting the distance between the cutting mounting base and the center of rotation, the cutting radius can be changed, thereby enabling the opening of holes of different diameters, which greatly improves the versatility and economy of the device.

[0011] Furthermore, the rotating body is provided with a groove passing through the axis of rotation.

[0012] Furthermore, the bracket is cylindrical with a handle at the top. The rotating body is a circular component located in the middle of the bracket, and a rotating shaft is located on the rotating body towards the handle. The drive mechanism is connected to the rotating shaft via a belt, and the cutting mounting seat is located on the rotating body in a direction away from the handle.

[0013] Furthermore, the support has a fixed column at its center, and the rotating shaft is rotatably located inside the fixed column.

[0014] Furthermore, the light alignment mechanism is an infrared generator, and the infrared light spot is clearly visible in most working environments, with strong resistance to ambient light interference, which further improves the accuracy and reliability of positioning.

[0015] The beneficial effects of this utility model are as follows: By tilting the cutting mechanism and cooperating with the light alignment mechanism, this utility model successfully solves the technical problems of poor quality, low efficiency, inability to form bevels in one step, and difficulty in centering in traditional hole-opening methods. Its overall structure is simple, easy to operate, and highly versatile, significantly reducing equipment and production costs while ensuring high-precision hole-opening quality.

[0020] Reference Figures 1-3 This embodiment of a container opening device includes a support 1, a rotating body 2 rotatably mounted on the support 1, and a drive mechanism 3 for driving the rotating body 2 to rotate. The rotating body 2 is provided with a cutting mounting seat 4, which is configured to fix the cutting mechanism at an angle 41 relative to the axis of rotation 21 of the rotating body 2. The angle 41 ranges from 30° to 60°. The support 1 is provided with a light alignment mechanism 5 on one side of the cutting mounting seat 4. The light emitted by the light alignment mechanism 5 is used to indicate the center of the hole to be opened. The light alignment mechanism 5 is an infrared generator.

[0021] The cutting mounting base 4 is equipped with a clamp assembly 42 for fixing the cutting mechanism.

[0022] The rotating body 2 is provided with a groove 22 passing through the axis of rotation 21, and the cutting mounting seat 4 can be slidably mounted on the rotating body 2 along a straight line.

[0023] The bracket 1 is cylindrical, and a handle 11 is provided on the top of the bracket 1. The rotating body 2 is a circular part located in the middle of the bracket 1. The rotating body 2 has a rotating shaft 23 in the direction of the handle 11. The driving mechanism 3 is connected to the rotating shaft 23 through a belt 31. The cutting mounting seat 4 is located on the rotating body 2 in the direction away from the handle 11. A fixed column 12 is provided in the center of the bracket 1, and the rotating shaft 23 is rotatably located in the fixed column 12.

[0024] The method of using this utility model is as follows: First, adjust and lock the tilt angle 41 of the cutting mounting base 4 according to the required bevel angle of the container to be drilled, usually set between 30° and 60°. Then, fix the cutting mechanism to the cutting mounting base 4 using the clamp assembly 42. If holes of different diameters need to be drilled, the cutting mounting base 4 can be slidably adjusted along the slide groove 22 on the rotating body 2 to set the required drilling radius.

[0025] Place the device near the area of ​​the container to be pierced, and activate the light alignment mechanism 5 to emit a visible light spot. Adjust the position of the entire device relative to the container so that the light spot emitted by the light alignment mechanism 5 precisely illuminates the pre-marked center point of the piercing on the container surface.

[0026] Start the drive mechanism 3 and the cutting mechanism. The drive mechanism 3 drives the rotating body 2 and the cutting mounting base 4 on it to rotate at a constant speed around the axis 21 via the belt 31. The cutting mechanism fixed on the cutting mounting base 4 then makes a circular motion. The operator can observe the state of the cutting sparks or slag and adjust the speed of the drive mechanism 3 in a timely manner to obtain the best cutting quality.
