Description

Technical Field

[0001] The invention relates to the technical field of head spinning, in particular to a spinning device for processing a hemispherical head. Background Art

[0002] A hemispherical head is a head consisting of half a spherical shell and a straight edge (cylindrical short section). The radius of curvature of the spherical shell is equal everywhere, and the force is uniform. When the diameter is small, the hemispherical head can be pressed as a whole, but when the diameter is large, it is difficult to press the whole head due to its large depth. Usually, several trapezoidal spherical petals of the same size and a circular spherical panel at the top center are welded together.

[0003] Some large and medium-sized hemispherical heads are made by spinning devices. Specifically, they are first spliced ​​and then stamped into semi-finished products with a certain curvature, and finally spun through a rotating device. However, there are some problems in the spinning process:

[0004] First, the pressure wheel and the spinning forming wheel are used in the spinning device. The two wheels spin the hemispherical head by adjusting their positions and rotating them. However, during the spinning process, the diameter of the hemispherical head keeps changing, causing the head to shake violently, which will affect the quality of the product after spinning.

[0005] In addition, a flamethrower is generally used in the spinning process, and the flame generated by the flamethrower is used to soften the head. However, the flame spraying is generally limited to the outer periphery of the head, and the inner wall cannot be heated quickly. On the other hand, the temperature of the flame is only effective at the ejection point, the heating range is low, the heat consumption is slow, and the heat energy loss is high. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a spinning device for hemispherical head processing, which overcomes the shortcomings of the prior art and effectively solves the problems of shaking during spinning, low heating range, high heat consumption and high heat energy loss.

[0037] In this embodiment, in the concentric positioning mechanism 4, with the cooperation of the triangular plate 44 and the connecting rod 49, the square plate 41 is driven to move through the servo guide rail 3, and a linkage can be formed between the center rod 42 and the two side rods 45, thereby realizing the synchronous movement of the center wheel 43 and the side wheels 46, thereby ensuring the stability of the hemispherical head during the spinning process. As the diameter of the hemispherical head continues to change, the head can always maintain stable rotation, which is beneficial to improving the quality of the product after spinning.

[0038] Example 3, refer to Figure 5-7 A spinning device for processing a hemispherical head, wherein the heating mechanism 5 is composed of a square door 51, a waste heat bin 52, a servo motor 53, a spindle 54, a disc 55, a long rod 56, a swing sleeve rod 57 and a flamethrower 58, wherein the square door 51 is fixedly connected to the top outer wall of the base 1, the waste heat bin 52 is arranged on one side of the square door 51, the servo motor 53 is fixedly connected to the top outer wall of the waste heat bin 52 by screws, and the spindle 54 is fixedly connected to the servo motor 53 by a coupling On the output shaft, the disc 55 is fixedly connected to the outer wall of one end of the main shaft 54, wherein a connecting column is provided on the side of the disc 55 away from the main shaft 54, the long rod 56 includes two, which are cross-distributed and are rotatably connected to the connecting column of the disc 55, the swing sleeve rod 57 is hinged to the outer wall of one end of the long rod 56, a plurality of nozzles are distributed on the flamethrower 58, the flamethrower 58 is fixedly connected to the inner wall of the swing sleeve rod 57, and the fixed end of the flamethrower 58 is connected to the inner wall of the swing sleeve rod 57.

[0039] In this embodiment, in the heating mechanism 5, when the disc 55 is driven to rotate by the servo motor 53, the flamethrower 58 can swing up and down periodically. Since there are two flamethrowers 58, not only can high temperature softening of the head be generated in a large range, but also the outer periphery and inner wall of the head can be softened at the same time, thereby improving the efficiency of heating. On this basis, high temperature can shuttle in the waste heat bin 52, slowing down the speed of heat loss and reducing the loss of heat energy.

When the center wheel 43 approaches or moves away from the hemispherical head, the triangular plate 44 will slide back and forth along the inner wall of the flat groove 6 to maintain stability.

[0043] Reference Fig. 9 The top outer wall of the base 1 is welded with a bent frame 24, and the top inner wall of the bent frame 24 is fixedly connected with a hydraulic push rod 7, and the bottom outer wall of the hydraulic push rod 7 is fixedly connected with a ball sleeve 8 through a flange, and the inner wall of the ball sleeve 8 is rotatably connected with a positioning ball 9. The ball sleeve 8 is pushed downward by the hydraulic push rod 7, and the positioning ball 9 inside the ball sleeve 8 can rotate along the lowest center position of the inner wall of the hemispherical head under the rotation of the hemispherical head.

[0044] Reference Fig. 9 The inner wall of the base 1 is fixedly connected with a hydraulic push rod 10, and the piston rod of the hydraulic push rod 10 is rotatably connected with a bottom bracket 11, and the top outer wall of the bottom bracket 11 is provided with an arc groove 12 for supporting the hemispherical head. The hemispherical head needs to be placed in the arc groove 12 before spinning, and the hemispherical head fits in the arc groove 12 for rotation.

[0045] Reference Fig. 9 The base 11 is rotatably connected with a supporting rod 13 around its periphery, and a bottom wheel 14 is rotatably connected to the outer wall of one end of the supporting rod 13, and a spring 15 is connected between the supporting rod 13 and the base 11. The bottom wheel 14 is used to support the bottom of the hemispherical head to prevent the hemispherical head from falling off the base 11.

[0046] Reference Figure 8A guide frame 16 is welded to one side of the outer wall of the top of the base 1, and a fixed column 18 is slidably connected to the inner wall of the guide frame 16. A hydraulic push rod 3 17 is hinged between the fixed column 18 and the guide frame 16. A driving motor 19 is fixedly connected to the outer wall of one end of the fixed column 18, and a pressure wheel 20 is fixedly connected to the output shaft of the driving motor 19. The fixed column 18 can be pushed by the hydraulic push rod 3 17 to control the fixed column 18 to move in a circular arc trajectory, and the bending direction of the hemispherical head is controlled under the rotation of the pressure wheel 20.

[0047] Reference Figure 8 The inner wall of the top of the bending frame 24 is fixedly connected with a hydraulic push rod 4 21, and the piston rod of the hydraulic push rod 4 21 is fixedly connected with a driving motor 22, and the output shaft of the driving motor 22 is fixedly connected with a spinning forming wheel 23. Under the propulsion of the hydraulic push rod 4 21, the driving motor 22 drives the spinning forming wheel 23 to rotate, so as to control the inner wall of the hemispherical head to be gradually bent into a hemispherical shape.

[0048] Working principle: First, place the steel material after stamping on the arc groove 12 of the bottom bracket 11, and then push the ball sleeve 8 downward through the hydraulic push rod 17, so that the positioning ball 9 inside the ball sleeve 8 is against the lowest center position of the inner wall of the hemispherical head;

[0049] Next, the fixed column 18 is pushed by the hydraulic push rod 3 17 to control the fixed column 18 to move in a circular arc trajectory, and the bending direction of the hemispherical head is controlled under the rotation of the pressure wheel 20. At the same time, under the pushing action of the hydraulic push rod 4 21, the spin forming wheel 23 is driven by the driving motor 22 to rotate, so that the inner wall of the hemispherical head can be gradually bent into a hemispherical shape;

[0050] During spinning, the square plate 41 is driven to move by the servo guide rail 3, so that the center rod 42 and the center wheel 43 and the side wheels 46 at one end of the two side rods 45 are close to the hemispherical head, ensuring the stability of the hemispherical head during the spinning process. In this process, the servo motor 53 drives the disc 55 to rotate, so that the flamethrower 58 can periodically swing up and down to spray flames at the outer periphery and inner wall of the head at the same time, thereby softening the hemispherical head and reducing the difficulty of spinning.
