Description

Technical Field

[0001] This invention relates to the field of end cap processing equipment, and more particularly to a butterfly end cap punching and forming device and its usage method. Background Technology

[0002] With the rapid development of the petrochemical and nuclear power industries, the size of large pressure vessels is gradually increasing. As one of the key components of large pressure vessels, the end cap is a large, thick-walled component, and its size increases with the size of the pressure vessel, thus increasing the difficulty of manufacturing.

[0003] Butterfly heads are a common type of head, typically manufactured using two processes: stamping and spinning. Stamping utilizes the plasticity of metal; sheet metal is formed by pressing under the action of molds and forming equipment, resulting in irreversible plastic deformation. The stamping force and blank holder force during stamping have a certain impact on the head forming effect, potentially causing problems such as wrinkles and excessively thin dome plates. Therefore, stamping is suitable for smaller diameters and thicker steel blanks. Spinning typically involves shaping a rotating steel blank using inner and outer spinning rollers, making it suitable for thinner steel blanks. However, it presents challenges for processing heads with thicker steel blanks. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a butterfly-shaped end cap punching and forming device and its usage method, which is suitable for processing end caps made of thicker sheet metal, thereby improving existing problems.

[0005] This invention is achieved through the following technical solution:

[0006] A butterfly-shaped end-forming device includes a base and a stamping mechanism disposed above the base. A liftable support seat is provided on the base directly below the stamping mechanism. A die is disposed on the support seat. Two sets of slide rails are provided on the base. A slidable end-shaped end-shaped support and rotation mechanism is disposed on the slide rails. The end-shaped end-shaped support and rotation mechanism includes three sets of support adjustment components for supporting and rotating the steel billet. The two sets of slide rails include a first slide rail and a second slide rail. The first slide rail is fixed to the front and rear sides of the support seat, and the second slide rail is fixed to the right side of the support seat. The three sets of support adjustment components include a first support adjustment component, a second support adjustment component, and a third support adjustment component. The first and second support adjustment components are disposed on the first slide rail and are symmetrical to each other, moving synchronously on the first slide rail. The third support adjustment component is disposed on the second slide rail. The end-shaped end-shaped support and rotation mechanism clamps the end-shaped ...

[0007] Further optimized, it also includes a receiving end and a transmitting end of a position sensor. A support rod is fixed on one side of the first support adjustment assembly. The receiving end is mounted on the support rod. The position of the receiving end is adjustable and moves with the first support adjustment assembly. The transmitting end is fixed on the support base and is perpendicular to the first slide rail.

[0008] Furthermore, a liftable support platform is provided between the second slide rails.

[0009] Further optimized, the first support adjustment assembly includes a sliding base, a lifting cylinder, a positioning rod, a connecting seat, a motor, rollers, and a drum. The sliding base is slidably mounted on a first track. The lifting cylinder and the positioning rod are fixed to the sliding base. The connecting seat is slidably mounted on the positioning rod. One end of the connecting seat is fixed to the piston rod of the lifting cylinder. The motor is fixed to the other end of the connecting seat. The rollers are fixed to the output shaft of the motor. The drum is rotatably mounted on the positioning rod and is located above the connecting seat.

[0010] In a further optimized configuration, the third support adjustment assembly includes a sliding frame, an angle adjustment frame, a slider, a second roller, a limit wheel, and two adjustment cylinders. The sliding frame is slidably mounted on the second slide rail. One end of the angle adjustment frame is hinged to one end of the sliding frame. The adjustment cylinders are respectively hinged to both sides of the sliding frame, and the output ends of the adjustment cylinders are hinged to both sides of the angle adjustment frame. The slider is slidably mounted on the angle adjustment frame, and the second roller and the limit wheel are mounted on the slider.

[0011] Further optimized, the limiting wheel is an irregularly shaped wheel, and the second roller is perpendicular to the limiting wheel.

[0012] Furthermore, the roller, the second roller, and the limiting roller are all provided with a wear-resistant rubber layer.

[0013] Further optimized, a) the support platform rises to the same height as the rollers, suspends the steel billet and places it on the rollers and support platform, then the third support adjustment assembly shifts, the rollers and limit wheels press against the steel billet, and the support platform falls; b) the receiving end of the position sensor is adjusted according to the diameter specification of the steel billet, so that the line connecting the receiving end and the center of the steel billet is perpendicular to the first slide rail; c) the three sets of support adjustment assemblies move synchronously towards the support seat, stopping when the receiving end of the position sensor receives the signal from the transmitting end, at which point the stamping mechanism and the die are directly opposite the center of the steel billet; d) the support seat rises. The die holds the steel billet in place, and the stamping mechanism performs the first stamping. After stamping, the third support adjustment component slightly loosens the steel billet. e. The angle adjustment frame rises to a certain angle, and the three sets of support adjustment components drive the steel billet to move to the right by a distance equal to the radius of the die. The rollers on the first and second support adjustment components rise slightly and rotate the steel billet. Then the rollers lower the steel billet, and the stamping mechanism performs stamping again. The process of rotating the steel billet and stamping is repeated multiple times. f. The angle adjustment frame raises the angle, and step e is repeated until the steel billet is stamped to the edge, forming a butterfly-shaped end cap.

[0014] The beneficial effects of this invention are:

[0015] The head support rotation mechanism clamps the head steel billet and slides it between the stamping mechanism and the die. After center positioning, the first stamping is performed. Then, under the displacement, rotation and angle adjustment of the support adjustment component, subsequent rotation stamping from the inside to the outside is performed. It has high processing accuracy and can be applied to steel billet plates of different diameters and thicknesses.

[0016] This device is equipped with a support platform to assist in hoisting and feeding. During feeding, the support platform is raised, and the steel billet is placed on the first support adjustment component, the second support adjustment component, and the support platform. Then, the third support adjustment component moves to tighten the steel billet. No manual assistance is required, making it safe, reliable, and easy to automate.

[0017] Before using this equipment, adjust the position of the position sensor receiver according to the billet diameter specifications, making it parallel to the center of the billet after it is tightened. The sensor receiver moves synchronously with the billet and the three sets of support adjustment components. The sensor radiating end is located on the support base. When the receiver receives the signal from the radiating end and stops moving, the billet is exactly below the stamping mechanism. Then, the center is stamped for the first time. No manual centering is required, making centering more accurate and improving processing precision. Attached Figure Description

[0030] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. In the description of this invention, it should be noted that the terms "left," "right," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0031] like Figures 1-7 As shown, the present invention provides a butterfly-shaped end cap forming device, including a base 1 and a stamping mechanism 2 disposed above the base. A liftable support seat 4 is provided on the base 1 directly below the stamping mechanism 2, and a die 41 is provided on the support seat 4. The base 1 is provided with two sets of slide rails, including a first slide rail 3 and a second slide rail 5. The first slide rail 3 is fixed to the front and rear sides of the support seat 4, and the second slide rail is fixed to the right side of the support seat 4.

[0032] The slide rail is equipped with a slidable head support and rotation mechanism, which includes three sets of support and adjustment components for supporting and rotating the steel billet. These three sets of components include a first support adjustment component 7, a second support adjustment component 8, and a third support adjustment component 9. The first and second support adjustment components 7 and 8 are symmetrically positioned on the first slide rail 3 and move synchronously on it. The third support adjustment component 9 is positioned on the second slide rail 5. The head support and rotation mechanism clamps the head steel billet 101 and slides it between the stamping mechanism 2 and the die 41. After center positioning, the first stamping is performed (e.g., ...). Figure 7 As shown), and then, under the displacement, rotation, and angle adjustment of the support adjustment component, subsequent rotational stamping from the inside out is carried out.

[0033] In a preferred embodiment, the device further includes a receiving end 62 and a transmitting end 63 of a position sensor. A support rod 61 is fixed to one side of the first support adjustment assembly 7. The receiving end 62 is mounted on the support rod 61 and can slide left and right on the support rod 61, and can move with the first support adjustment assembly 7. The transmitting end 63 is fixed on the support base 4 and perpendicular to the first slide rail 3. Before using this device, the position of the receiving end is adjusted according to the diameter specification of the steel billet, so that it is parallel to the center of the steel billet after it is tightened. The three sets of support adjustment assemblies drive the steel billet to slide to the left. When the receiving end receives the signal from the transmitting end, the displacement stops, and the steel billet is exactly below the stamping mechanism. Then, the center is stamped for the first time. No manual centering is required, the centering is more accurate, and the processing precision is higher.

[0034] In a preferred embodiment, a liftable support platform 11 is also provided between the second slide rails 5. Before placing the steel billet, the first support adjustment assembly 7 and the second support adjustment assembly 8 are on the left side of the support platform 11, and the third support adjustment assembly 9 is on the right side of the support platform. The support platform is raised first to be at the same height as the rollers 77 of the first support adjustment assembly 7 and the second support adjustment assembly 8. Then, the steel billet is placed on the support platform 11 and the rollers 77 by hoisting or other equipment. Then, the third support adjustment assembly 9 moves to the left to press against the steel billet, and the support platform 11 falls down. The three sets of support adjustment assemblies drive the steel billet to move synchronously to the left.

[0035] In a preferred embodiment, the first support adjustment assembly includes a sliding base 71, a lifting cylinder 72, a positioning rod 75, a connecting seat 73, a motor 76, a roller 77, and a drum 74. The sliding base 71 is slidably mounted on the first track 3. The lifting cylinder 72 and the positioning rod 75 are fixed to the sliding base 71. The connecting seat 73 is slidably mounted on the positioning rod 75. One end of the connecting seat 73 is fixed to the piston rod of the lifting cylinder 72. The motor 76 is fixed to the other end of the connecting seat 73. The roller 77 is fixed to the output shaft of the motor. The drum 74 is rotatably sleeved on the positioning rod 75 and is located above the connecting seat 73. During stamping, the connecting seat 73 rises, lifting the steel billet. The motor 76 operates, and the roller drives the steel billet to rotate at a certain angle. Then, the connecting seat descends, placing the steel billet onto the die for the next stamping. The drum serves to limit the movement of the steel billet and can rotate, preventing the positioning pin from affecting the rotation of the steel billet.

[0036] In a preferred embodiment, the third support adjustment assembly 9 includes a sliding frame 96, an angle adjustment frame 92, a slider 93, a second roller 94, a limiting wheel 95, and two adjusting cylinders 91. The sliding frame 96 is slidably mounted on the second slide rail 5. One end of the angle adjustment frame 92 is hinged to one end of the sliding frame 96. The adjusting cylinders 91 are respectively hinged to both sides of the sliding frame 96, and the output ends of the adjusting cylinders 91 are hinged to both sides of the angle adjustment frame 92. The slider 93 is slidably mounted on the angle adjustment frame 92. The second roller 94 and the limiting wheel 95 are mounted on the slider. The second roller is an auxiliary roller, which, together with the rollers on the first and second support adjustment assemblies, supports the steel billet and assists in the rotation of the steel billet. The limiting wheel 95 prevents the steel billet from sliding. After the first stamping, the steel billet is displaced to the right by a distance equal to the radius of the die, and then rotated for stamping. This process is repeated until the edge of the steel billet is stamped, forming a butterfly-shaped end cap. During the above displacement process, the angle adjustment frame 92 gradually increases the angle, and the slider 93 slowly slides on the angle adjustment frame to adapt to the angle change of the end cap 10.

[0037] In a preferred embodiment, the limiting wheel 95 is an irregularly shaped wheel, and the second roller 94 is perpendicular to the limiting wheel 95.

[0038] As a preferred embodiment, the roller 77, the second roller 94 and the limiting roller 95 are all provided with a wear-resistant rubber layer, which not only resists wear but also prevents slippage when rotating the steel billet, so as to achieve immediate movement and stop, rapid response and more precise rotation angle.

[0039] More specifically, the usage method and process of this device are as follows:

[0040] a. The support platform 11 is raised to the same height as the roller 77, the steel billet is lifted and placed on the roller and support platform, then the third support adjustment component is moved to the left, the limit wheel 95 cooperates with the roller to tighten the steel billet, and then the support platform is lowered.

[0041] b. Adjust the position of the sensor receiver 62 according to the diameter specification of the steel billet, so that the line connecting the receiver and the center of the steel billet is perpendicular to the first slide rail, and then fix it. This step only needs to be adjusted once when processing the first end cap of the same specification.

[0042] c. The three sets of support adjustment components move synchronously towards the support base 4. The movement stops when the receiver of the position sensor receives a signal from the transmitter. At this point, the stamping mechanism 2 and the die 41 are aligned with the center of the steel billet. Figure 7 As shown;

[0043] d. The support base 4 rises, the die holds the steel billet, the stamping mechanism 2 performs the first stamping, and after stamping, the third support adjustment component 9 slightly loosens the steel billet;

[0044] e. The angle adjustment frame 92 is raised to a certain angle, and the three sets of support adjustment components drive the steel billet to move to the right by a distance of one die radius. The rollers 77 on the first support adjustment component 7 and the second support adjustment component 8 are slightly raised and rotate the steel billet. Then the rollers drop the steel billet, and the stamping mechanism performs stamping again. Then the steel billet is rotated and stamped multiple times.

[0045] f. Raise the angle of the angle adjustment bracket 92 and repeat step e until it is stamped to the edge of the steel billet to form a butterfly head 101.
