Description

Technical Field

[0001] This invention relates to the field of head manufacturing technology, specifically to a welding equipment for conical head welds. Background Technology

[0002] Conical heads are heads with a conical shell surface, widely used in pressure vessels, chemical equipment, oil storage tanks, and other industrial fields, serving as one of the main pressure components in these devices. Their unique conical structure effectively disperses and withstands internal pressure, enhancing structural stability and safety. Simultaneously, it facilitates the smooth guidance of fluids or gases, reducing flow resistance, and in certain applications, optimizes material mixing and heat transfer efficiency. Conical heads are manufactured using a variety of materials, including stainless steel, carbon steel, and alloy steel, to meet the requirements of different industrial sectors for corrosion resistance, high temperature resistance, or high strength.

[0003] Patent application CN202310852212.1 proposes a manufacturing process for end caps, which involves placing six plates circumferentially on a welding machine for welding. However, in this device, the top of the welding seat has a notch that matches the end cap, resulting in a limited range of end cap shapes and sizes that the welding seat can process. Furthermore, the welding fixtures for conical end caps with different angles are inconvenient.

[0004] To address this, the patent application with application number CN202410824608.X proposed an improvement by setting a replaceable welding mold base to accommodate conical heads with different inclinations, and by adjusting the positioning fixture, limiting and fixing the top of each head splicing steel plate, which facilitates limiting conical heads of different diameters; while we have proposed another simple device to limit plates with different inclinations to assist in weld welding.

[0005] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to design a device that can limit the movement of plates with different slopes to assist in the welding of tapered head welds, thereby overcoming the aforementioned shortcomings in the technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tapered head welding device for clamping the plate of the tapered head at a required angle to assist in welding, comprising multiple horizontally moving components arranged in a circular array, a clamping guide fixedly installed on the output end of the horizontally moving components, the clamping guide having a receiving cavity inside, a through groove opened at one corner of the top of the receiving cavity, a top roller rotatably installed on the top of one side of the clamping guide on the through groove, a pressure roller provided at the bottom of the other side of the through groove, and a vertically moving component installed on the clamping guide to control the vertical distance between the pressure roller and the top roller, wherein when the plate is inserted into the through groove, the center of gravity of the plate is always on the side of the top roller away from the pressure roller;

[0008] When the plate is inserted into the through groove, the top roller acts as a fulcrum. Under the action of the center of gravity and gravity, the part of the plate in the receiving cavity tilts upward and contacts the pressure roller. The plate will slide into the receiving cavity until it contacts the surface of the clamping guide and can no longer swing. By utilizing the different vertical distances between the top roller and the pressure roller, the plate can be tilted to the required angle.

[0009] Preferably, the clamping guide includes a base, a vertical plate mounted on one side of the base, a support plate fixedly mounted on the other side of the base, and a horizontal plate mounted on the top of the support plate. The top roller is rotatably mounted on the top of the vertical plate. The gap between the top of the vertical plate and the end of the horizontal plate forms the through groove. The cavity between the vertical plate, the base, the support plate, and the horizontal plate forms a receiving cavity.

[0010] Preferably, the vertical moving assembly includes two guide rods penetrating the horizontal plate, a connecting rod fixedly installed between the top ends of the two guide rods, a first threaded shaft penetrating and threadedly connected inside the connecting rod, and a handle fixedly installed at the top end of the first threaded shaft. The bottom end of the first threaded shaft is rotatably connected to the horizontal plate, and both ends of the pressure roller are rotatably connected to the bottom ends of the two guide rods respectively.

[0011] Preferably, the guide rod is engraved with a scale that cooperates with the horizontal plate to show the vertical height between the pressure roller and the top roller.

[0012] Preferably, a transmitter of a distance sensor can be fixedly installed at the bottom of the guide rod, and a receiver of the distance sensor that cooperates with the transmitter is fixed on the side wall of the horizontal plate. The receiver cooperates with the transmitter to determine the vertical distance between the top roller and the pressure roller.

[0013] Preferably, the top roller is detachably mounted on the clamping guide, and the pressure roller is detachably mounted on the vertical moving member. When the plate is planar, both the top roller and the pressure roller are cylindrical. When the plate is non-planar, the top roller is spindle-shaped, and the pressure roller is a single-leaf hyperboloid.

[0014] Preferably, the horizontal moving component includes a guide rail located at the bottom of the base, a second threaded shaft rotatably mounted on the guide rail, and a connecting block that passes through and is threadedly connected to the second threaded shaft. The connecting block is fixedly connected to the bottom of the base, and a roller that is rotatably mounted on the bottom of the base and is rolledly connected to the guide rail.

[0015] Preferably, the vertical plate can also be configured as a vertical adjustment module with adjustable vertical height, and the horizontal plate can also be configured as a horizontal adjustment module with adjustable horizontal length.

[0016] Preferably, a polygonal block is provided between the plurality of horizontal moving components, the number of sides of the polygonal block matching the number of guide rails, and the ends of the guide rails fitting against the sidewalls of the polygonal blocks.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. The present invention, by setting up a clamping guide, a top roller and a pressure roller, ensures that when the plate passes through the through groove and is inserted into the receiving cavity, the plate is always on the side of the top roller away from the pressure roller due to gravity and its own center of gravity. This allows the plate to be inserted at an angle until it contacts the clamping guide. The top roller, pressure roller and clamping guide are used to limit the change of the angle between the plate and the horizontal plane, thereby ensuring the stability of the plate during welding and assisting in the welding of the weld.

[0019] 2. This invention adjusts the slope of the plate when it is limited by adjusting the vertical distance between the central axes of the top roller and the pressure roller, thus making it suitable for tapered end cap plates of different widths. While retaining the limiting function, it also has the function of adjusting the slope.

[0020] 3. At the same time, when adjusting the vertical distance between the central axes of the top roller and the pressure roller, the thickness of the plate can also be taken into consideration. This invention is applicable not only to tapered end plates with different widths, but also to tapered end plates with different thicknesses.

[0021] 4. Compared with the equipment in the prior art, the present invention has a simple structure and is easy to operate. When limiting the slope of the plate, it can also push the plate along the central axis of the top roller to center it, ensuring the accuracy of auxiliary welding. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] This invention provides, for example Figure 1-6 The conical head welding equipment shown is used to clamp the plate 1 of the conical head at the required angle with the horizontal plane, so that it cannot swing and adjust the angle with the horizontal plane, so that the weld gap formed with the adjacent plate 1 is the same from top to bottom, thereby assisting in the welding.

[0034] The system includes a central polygonal block 12, the number of which corresponds to the number of plates 1. Each side of the polygonal block 12 is fitted with a guide rail 201. A second threaded shaft 202 is threaded onto the guide rail 201. A connecting block 203 is threaded through and threaded onto the second threaded shaft 202. When the second threaded shaft 202 rotates, it causes the connecting block 203 to move closer to or away from the polygonal block 12. A base 301 is fixedly mounted on the connecting block 203. A roller 204, which is rotatably connected to the guide rail 201, is also rotatably mounted on the bottom of the base 301. The guide rail 201 and the second threaded shaft... 202, connecting block 203, and roller 204 constitute the horizontal moving assembly 2 that drives the base 301 to move linearly. A vertical plate 302 is fixedly installed on the top of the base 301 near the polygonal block 12, and a support plate 303 is fixedly installed on the other side. A horizontal plate 304 is fixedly installed on the top of the support plate 303. The gap between the side of the horizontal plate 304 near the polygonal block 12 and the top of the vertical plate 302 forms a through groove 5. The cavity between the vertical plate 302, the base 301, the support plate 303, and the horizontal plate 304 forms a receiving cavity 4. The support plate 303 and the horizontal plate 304 constitute the clamping guide 3. A top roller 6 is detachably and rotatably mounted on the top of the vertical plate 302. Two guide rods 801 are slidably mounted through and within the horizontal plate 304. A pressure roller 7 is rotatably mounted between the bottom ends of the two guide rods 801. A connecting rod 802 is fixedly mounted between the top ends of the two guide rods 801. A first threaded shaft 803 is threaded through and connected threadedly within the connecting rod 802. The bottom end of the first threaded shaft 803 is rotatably connected to the horizontal plate 304. A handle 804 is fixedly mounted on the top end of the first threaded shaft 803. Here, the guide rods 801... 1. The connecting rod 802, the first threaded shaft 803, and the handle 804 constitute the vertical moving assembly 8 for adjusting the vertical distance between the pressure roller 7 and the top roller 6. Here, the vertical distance refers to the distance between the central axis of the pressure roller 7 and the central axis of the top roller 6. In order to ensure that the vertical distance is quickly adjusted to the required distance, we engrave a scale 9 on the guide rod 801 to cooperate with the horizontal plate 304 to determine the vertical distance. Alternatively, a transmitter 10 of a distance sensor can be fixedly installed at the bottom of the guide rod 801, and a receiver 11 of a distance sensor that cooperates with the transmitter 10 can be fixedly installed on the side wall of the horizontal plate 304.

[0035] In practical use, we first need to determine whether the board 1 is a flat or non-planar curved surface. If it is flat, we replace both the top roller 6 and the pressure roller 7 with cylindrical shapes. If it is a non-planar curved surface, we need to replace the top roller 6 with a shuttle shape and the pressure roller 7 with a single-leaf hyperboloid shape. In short, we select top roller 6 and pressure roller 7 with matching sizes and shapes to ensure that both sides of the board 1 make line contact with the pressure roller 7 and top roller 6 respectively. Then, we calculate the vertical distance between the pressure roller 7 and top roller 6 that needs to be adjusted based on the angle required to be adjusted for the board 1. For details, please refer to... Figure 6As shown, the vertical distance between the central axes of top roller 6 and pressure roller 7 is known as A, and the horizontal distance between the central axes of top roller 6 and pressure roller 7 is known as B. Then, the inclined distance C between the central axes of top roller 6 and pressure roller 7 can be calculated using right-angle trigonometric functions. Then, the angle X between the side of the inclined distance C and the side of the horizontal distance B can be obtained. The radii of top roller 6 and pressure roller 7 are the same and known as D. The thickness of plate 1 is known as E. Since top roller 6 and pressure roller 7 are in line contact with plate 1 and tangent, E / 2+D is a short side of the newly formed right triangle. The hypotenuse of the newly formed right triangle is C / 2. Then, the angle Y between the long side and the hypotenuse of the newly formed right triangle can be calculated using right-angle trigonometric functions. Thus, the angle Z between plate 1 and the horizontal plane can be obtained. Conversely, if we need plate 1 to be at the required angle Z, such as 45°, then the value of A can be calculated.

[0036] After determining the vertical distance between the centerlines of the top roller 6 and the pressure roller 7 according to the required angle adjustment of the plate 1, the operator rotates the handle 804 to drive the threaded rod, which drives the connecting rod 802, thereby driving the guide rod 801, which in turn drives the pressure roller 7 to move up and down until the scale 9 and the horizontal plate 304 reach the required value, or the receiver 11 and transmitter 10 of the distance sensor cooperate to display the required value on the existing control panel;

[0037] like Figure 5 As shown, the worker then inserts the plate 1 into the through groove 5. Since the center of gravity of the plate 1 is located on the side of the top roller 6 away from the pressure roller 7, the plate 1 will rotate counterclockwise with the top roller 6 as the fulcrum, causing the side of the plate 1 inserted into the receiving cavity 4 to tilt up and make line contact with the outer circumference of the pressure roller 7. At the same time, the plate 1 will descend under its own weight, that is, when the top roller 6 rotates clockwise, the plate 1 is inserted to the lower right until the plate 1 contacts the top surface of the base 301. At this time, if the angle Z between the plate 1 and the horizontal plane is to be increased, the plate 1 can only rotate clockwise around the top roller 6. The contact between the plate 1 and the top surface of the base 301 restricts the swing of the plate 1. If the angle Z is to be decreased, the plate 1 can only rotate counterclockwise around the top roller 6, which is again restricted by the pressure roller 7. Therefore, the angle between the plate 1 and the horizontal plane is restricted. At this time, the worker can push the plate 1 along the length of the central axis of the top roller 6 to center the plate 1. Since the plate 1, the top roller 6, the bottom roller and the base 301 are essentially in line contact, it is relatively easy to push.

[0038] Finally, as needed, drive the second threaded shaft 202 to rotate, which in turn drives the connecting block 203, thereby causing the base 301 to move on the guide rail 201, so that multiple plates 1 approach each other in an arc shape to form the overall frame of the conical head. Then, the welds between the plates 1 are welded by manual or automated means.

[0039] Alternatively, a vertical adjustment module with adjustable vertical height can be set, and a horizontal adjustment module with adjustable horizontal length can be set for the horizontal plate 304. For example, by lowering the height of the top roller 6 and reducing the horizontal distance between the top roller 6 and the pressure roller 7, the top roller 6 can be moved further away from the center of gravity of the plate 1.

[0040] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
