Description

Technical Field

[0001] This utility model belongs to the field of large-diameter head manufacturing technology, and in particular, it is a tooling for manufacturing large-diameter heads. Background Technology

[0002] An end cap is a component used to seal the end of a container and isolate the internal and external media. It is also called an end cap and is a key pressure-bearing component of the container. It is usually connected to the cylinder by welding. The core function of the end cap is to form the upper and lower bottom of the tank-shaped pressure vessel and to permanently seal the end of the pipeline to prevent media leakage and ensure the safe and stable operation of the equipment. Its quality directly affects the long-term reliability of the pressure vessel.

[0003] Large-diameter head fabrication fixtures refer to complete sets of process equipment and auxiliary devices specifically designed for the production, processing, and assembly of large heads (such as end-sealing components of pressure vessels and storage tanks). These fixtures provide precise control, efficient operation, and quality assurance throughout the manufacturing process of large-diameter heads (material preparation → forming → welding → shaping → inspection). Essentially, they solve the operational challenges posed by ultra-large workpieces (such as deformation control, heavy-duty lifting, and high-precision matching) through mechanization.

[0004] When using existing large-diameter head manufacturing fixtures for cold stamping, lubricating oil needs to be applied to the stamping surface of the material to be stamped. For heads of Φ4m and above, multiple people need to work together. When operators stand outside the head and apply the oil manually, the edge areas (such as flange edges and straight edges) are easier to reach, and they tend to apply the oil repeatedly to ensure coverage. However, due to blind spots and arm extension limitations, it is difficult to accurately control the amount of oil applied to the curved surface in the center of the head. This can lead to lubricating oil accumulating at the edges and being thin in the center when applied manually.

[0005] The purpose of this invention is to provide a tooling for manufacturing large-diameter heads to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a tooling for manufacturing large-diameter heads to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tooling for manufacturing large-diameter end caps, including a worktable, a support arm provided on the worktable, and a forming hole provided on the worktable; The support arm is provided with an electric telescopic rod on one side, and the telescopic end of the electric telescopic rod is provided with a moving mechanism. The support arm is provided with a limiting mechanism on one side. The slider in the moving mechanism is connected to the slide rail in the limiting mechanism through a connecting rod. The upper end of the slider is provided with a motor, and the shaft of the motor is provided with a coating mechanism. The slide rail in the limiting mechanism is inclined downward at the end near the forming hole; When the electric telescopic rod extends, it drives the horizontal plate in the moving mechanism to move toward the forming hole. When the horizontal plate moves laterally, it drives the slider to move synchronously. When the slider moves laterally, it drives the connecting rod to move laterally in the slide rail. When the slider moves laterally, it drives the motor to move synchronously to the center of the forming hole. When the slider moves to the center of the forming hole, the connecting rod will move downward at an incline in the slide rail. When the connecting rod moves downward at an incline, it drives the slider to move downward synchronously. When the slider moves downward, it drives the motor to move downward synchronously. When the motor moves downward, it drives the support frame in the coating mechanism to move downward. When the support frame moves downward, it drives the oil tank in the coating mechanism to move downward. When the oil tank moves downward, it drives the ball bearing in the coating mechanism to move downward synchronously until the ball bearing is moved to contact the surface of the workpiece to be formed. At this time, the length of the ball bearing is the same as the radius of the workpiece to be formed, and one end of the ball bearing is located at the center of the workpiece to be formed. When the motor shaft rotates, it drives the support frame to rotate synchronously. When the support frame rotates, it drives the oil tank to rotate synchronously. When the oil tank rotates, it drives the ball bearings to rotate on the surface of the workpiece to be formed. When the ball bearings rotate, the lubricating oil in the oil tank is applied to the surface of the workpiece to be formed.

[0008] Furthermore, the moving mechanism includes a horizontal plate, a sliding groove, and a slider. The telescopic end of the electric telescopic rod is provided with a horizontal plate, and a sliding groove is provided on the horizontal plate. A slider is slidably disposed in the sliding groove to facilitate control of the vertical movement of the ball.

[0009] Furthermore, the limiting mechanism includes a connecting plate and a slide rail. One end of the support arm is provided with a connecting plate, and a slide rail is provided in the connecting plate. The end of the connecting rod located in the slide rail is spherical, which facilitates the control of the position of the connecting rod.

[0010] Furthermore, the coating mechanism includes a support frame, an oil tank, an oil inlet, an oil delivery hole, and ball bearings. The motor shaft is provided with a support frame, and the support frame contains an oil tank. The oil tank has an oil inlet at its upper end and multiple equidistant oil delivery holes inside. A ball bearing is rotatably arranged at the lower end of each oil delivery hole in the oil tank to facilitate the uniform application of lubricating oil to the surface of the workpiece to be formed.

[0011] Furthermore, a hydraulic telescopic rod is provided at one end of the support arm corresponding to the workbench, and a stamping head is provided at the telescopic end of the hydraulic telescopic rod to stamp the workpiece to be formed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a moving mechanism mounted on an electric telescopic rod, a behavioral mechanism mounted on a support arm, and a coating mechanism mounted on a motor shaft. The electric telescopic rod extends, causing the motor on the slider to move to the center of the forming hole. Simultaneously, the slider slides downwards via a connecting rod within a slide rail, tilting until the ball bearings land on the surface of the workpiece to be formed. The motor is then activated, causing the support frame and its oil tank to rotate. As the oil tank rotates, it drives the ball bearings to rotate on the surface of the workpiece, evenly coating the surface with lubricating oil. This solves the problem in the prior art where the curved surface at the center of the end cap is difficult to precisely control due to blind spots and arm extension limitations, leading to lubricating oil accumulation at the edges and a weak center when manually brushed.

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0017] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] Please see Figures 1 to 5 As shown, this utility model provides a tooling for manufacturing large-diameter end caps, including a workbench 1, on which a support arm 2 is provided to support a hydraulic telescopic rod 3, and a forming hole 5 is provided on the workbench 1 to enable the workpiece to be formed by stamping through the cooperation of a stamping head 4.

[0020] Among them, an electric telescopic rod 6 is provided on one side of the support arm 2, and a moving mechanism 7 is provided at the telescopic end of the electric telescopic rod 6. A limiting mechanism 8 is provided on one side of the support arm 2. The slider 703 in the moving mechanism 7 is connected to the slide rail 802 in the limiting mechanism 8 through a connecting rod 9. A motor 10 is provided at the upper end of the slider 703, and a coating mechanism 11 is provided on the shaft of the motor 10. The slide rail 802 in the limiting mechanism 8 is inclined downward at the end near the forming hole 5; When the electric telescopic rod 6 extends, it drives the horizontal plate 701 in the moving mechanism 7 to move toward the forming hole 5. When the horizontal plate 701 moves laterally, it drives the slider 703 to move synchronously. When the slider 703 moves laterally, it drives the connecting rod 9 to move laterally in the slide rail 802. When the slider 703 moves laterally, it drives the motor 10 to move synchronously to the center of the forming hole 5. When the slider 703 moves to the center of the forming hole 5, the connecting rod 9 will move downwards at an angle in the slide rail 802. When the connecting rod 9 moves downwards at an angle, it drives the slider 703 to move downwards synchronously. When the slider 703 moves downwards, it drives the motor 10 to move downwards synchronously. When the motor 10 moves downwards, it drives the support frame 1101 in the coating mechanism 11 to move downwards. When the support frame 1101 moves downwards, it drives the oil tank 1102 in the coating mechanism 11 to move downwards. When the oil tank 1102 moves downwards, it drives the ball bearing 1105 in the coating mechanism 11 to move downwards synchronously until the ball bearing 1105 is moved to contact the surface of the workpiece to be formed. At this time, the length of the ball bearing 1105 is the same as the radius of the workpiece to be formed, and one end of the ball bearing 1105 is located at the center of the workpiece to be formed. When the motor 10 shaft rotates, it drives the support frame 1101 to rotate synchronously. When the support frame 1101 rotates, it drives the oil tank 1102 to rotate synchronously. When the oil tank 1102 rotates, it drives the ball bearing 1105 to rotate on the surface of the workpiece to be formed. When the ball bearing 1105 rotates, the lubricating oil in the oil tank 1102 is applied to the surface of the workpiece to be formed. It is used to achieve precise control of the coating amount, thereby avoiding the problem of lubricating oil accumulating at the edges and being weak in the center when manually brushed.

[0021] The moving mechanism 7 includes a horizontal plate 701, a slide groove 702, and a slider 703. The telescopic end of the electric telescopic rod 6 is provided with a horizontal plate 701. A slide groove 702 is provided on the horizontal plate 701, which is used to ensure the stable vertical sliding of the slider 703. The slider 703 is slidably arranged in the slide groove 702.

[0022] The limiting mechanism 8 includes a connecting plate 801 and a slide rail 802. One end of the support arm 2 is provided with the connecting plate 801, and the slide rail 802 is provided in the connecting plate 801. It is used to determine the second sliding trajectory of the connecting rod 9 and to ensure the stability of the sliding of the connecting rod 9. One end of the connecting rod 9 located in the slide rail 802 is spherical, which is used to reduce the friction when the connecting rod 9 slides in the slide rail 802, so as to make the connecting rod 9 slide smoothly in the slide rail 802.

[0023] The coating mechanism 11 includes a support frame 1101, an oil tank 1102, an oil inlet 1103, an oil delivery hole 1104, and ball bearings 1105. The shaft of the motor 10 is provided with a support frame 1101. The support frame 1101 contains an oil tank 1102 for storing lubricating oil. An oil inlet 1103 is provided at the upper end of the oil tank 1102 for injecting lubricating oil into the oil tank 1102. The oil tank 1102 has multiple equidistant oil delivery holes 1104 for evenly delivering the lubricating oil in the oil tank 1102 to the ball bearings 1105. A ball bearing 1105 is rotatably arranged at the lower end of each oil delivery hole 1104 in the oil tank 1102 for evenly coating the lubricating oil onto the surface of the workpiece to be formed by the rolling of the ball bearings 1105.

[0024] The support arm 2 is equipped with a hydraulic telescopic rod 3 at one end corresponding to the workbench 1. This rod is used to enable the stamping head 4 to move vertically back and forth. The telescopic end of the hydraulic telescopic rod 3 is equipped with the stamping head 4, which is used to stamp and form the workpiece to be formed.

[0025] Working principle: When it is necessary to apply lubricating oil to the surface of the workpiece to be formed, the electric telescopic rod 6 is first extended to drive the horizontal plate 701 to move towards the forming hole 5. When the horizontal plate 701 moves laterally, it drives the slider 703 to move synchronously. When the slider 703 moves laterally, it drives the connecting rod 9 to move laterally within the slide rail 802. When the slider 703 moves laterally, it drives the motor 10 to move synchronously to the center of the forming hole 5. When the slider 703 moves to the center of the forming hole 5, the connecting rod 9 will move downwards at an angle in the slide rail 802. When the connecting rod 9 moves downwards at an angle, it drives the slider 703 to move downwards synchronously. When the slider 703 moves downwards, it drives the motor 10 to move downwards synchronously. When the motor 10 moves downwards, it drives the support frame 1101 to move downwards. When the support frame 1101 moves downwards, it drives the oil tank 1102 to move downwards. When the oil tank 1102 moves downwards, it drives the ball bearing 1105 to move downwards synchronously until the ball bearing 1105 is moved to contact the surface of the workpiece to be formed. At this time, the length of the ball bearing 1105 is the same as the radius of the workpiece to be formed, and one end of the ball bearing 1105 is located at the center of the workpiece to be formed. Next, start the motor 10, so that when the motor 10 shaft rotates, it drives the support frame 1101 to rotate synchronously. When the support frame 1101 rotates, it drives the oil tank 1102 to rotate synchronously. When the oil tank 1102 rotates, it drives the ball bearing 1105 to rotate on the surface of the workpiece to be formed. When the ball bearing 1105 rotates, it causes the lubricating oil in the oil tank 1102 to be applied to the surface of the workpiece to be formed.
