Description

Technical Field

[0001] The invention belongs to the technical field of flange forging, and in particular relates to a flange forging device and a forging method. Background Art

[0002] Flange forging is a process that changes the shape and internal structure of metal by applying pressure to it. In flange forging, metal materials (such as stainless steel, carbon steel, etc.) are usually heated to a certain temperature using a die, and then hammered or pressed by a press to obtain the desired flange shape and size;

[0003] In the current flange forging process, the worker usually uses a handheld rod to place the flange blank or formed part under the punch for hammering. However, in the forging process of a larger flange, each position is forged more than once, or only a small part is forged, and the flange needs to be rotated and forged multiple times in a transposed position, which requires the worker to constantly adjust the position of the flange. During the adjustment process, the flange will shift in position. When forging again, the position of the flange and the punch needs to be adjusted, which greatly reduces the overall forging efficiency.

[0004] In view of this, a flange forging device and a flange forging method are proposed. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

The rotating shaft and the guide sleeve are linked through a linkage frame, and both ends of the linkage frame are in a movably docked relationship on the guide sleeve and the rotating shaft.

[0019] A flange forging method comprises the following steps:

[0020] S1. Place the heat-treated flange or blank on the operating panel. Under the control of the motor, the linkage column can link the rotating shaft and the linkage frame, so that the guide sleeve can move toward the flange with the guide rail as the track. At this time, the flange can be moved to the center of the operating panel. Under the action of the guide roller, the angle of the flange can be adjusted.

[0021] S2. After adjusting to the appropriate position, drive the hydraulic cylinder 2. At this time, the linkage frame can be linked to the linkage sleeve under the action of the tooth pattern 2. At this time, the pillar 1 and the pillar 2 rotate in opposite directions, the limiting member 1 gradually deviates from the flange, and the limiting member 2 gradually approaches the position of the flange. When the bearing frame 2 rotates to the position of the trapezoidal block and the arc plate, with the continuous rotation, the linkage cap contacts the hypotenuse of the trapezoidal block. At this time, under the action of the wedge-shaped fit, the linkage cap can be pushed to the outside position. At this time, the linkage cap and the hollow spline shaft are not connected. When reaching the plane position of the trapezoidal block, the linkage cap bites with the tooth pattern 1, so that the linkage cap can be rotated in a linked manner, so that the linkage shaft can be driven to rotate, so that the corresponding fitting pad can be adaptively adjusted to act on the flange according to the specifications of the flange.

[0022] S3, at this time, the flange is limited, and under the action of the driving hydraulic cylinder 1, the forging operation can be performed on the flange through the forging piece;

[0023] S4. After the single-position forging of the flange, the hydraulic cylinder 2 can be operated in the reverse direction so that the limiting member 1 fits with the surface of the flange again. At this time, the flange can be rotated, and the flange does not change during the rotation process, thereby improving the multi-stage forging effect of the flange.

[0024] Beneficial effects of the present invention:

[0025] The flange forging device is driven by the hydraulic cylinder 2, so that the linkage frame can rotate in a linkage manner with the linkage sleeve under the action of the tooth pattern 2, so as to control the reverse rotation of the pillar 1 and the pillar 2. When the limiting member 1 deviates from the flange and the limiting member 2 is close to the flange, the flange can be accurately limited at this time, which can avoid the position deviation of the flange during forging. When the limiting member 2 deviates from the flange and the limiting member 1 is close to the flange, the position of the flange is still in a limited state, and the flange can be operated to rotate, so as to facilitate continuous forging at different positions after a single forging, thereby improving the efficiency of forging.

[0026] When the flange forging device rotates to the position of the trapezoidal block and the arc plate through the bearing frame 2, the linkage cap contacts the bevel of the trapezoidal block. At this time, under the action of the wedge-shaped fit, the linkage cap can be pushed to the outside position. At this time, the linkage cap and the hollow spline shaft are not connected. When the plane position of the trapezoidal block is reached, the linkage cap bites with the tooth pattern, so that the linkage cap can be rotated in a linked manner, thereby driving the linkage shaft to rotate, so that the corresponding fitting pad can be adaptively adjusted according to the specifications of the flange to act on the flange;

[0027] The flange forging device can put in and take out the flange by limiting the components when they move outwardly.

Here, when the forging part 35 is designed to be large, it can be directly applied to the blank, and when the forging part 35 is designed to be small, the position can be movably adjusted and applied to various positions of the flange, wherein the hydraulic cylinder 32 can operate the support disk 33 and the forging part 35 to forge toward the flange.

[0048] Reference Figure 1 , 2 , 3 and 4, a circular pad 50, a guide rail 51 and a control component 20 are arranged in the linkage cavity 11, the circular pad 50 is arranged in the linkage cavity 11, the surface of the support seat 10 is provided with an operating disk 52, the operating disk 52 and the circular pad 50 are connected by a supporting roller, the guide rail 51 is arranged in an equal angle array on the peripheral wall surface of the circular pad 50, the outer end of the guide rail 51 is fixedly connected to the inner edge of the linkage groove 13, the guide rail 51 is reciprocatingly telescopically provided with a limiting component 60, and the control component 20 is arranged in the linkage cavity 11;

[0049] Reference Figure 5 and 7 The limiting component 60 includes a guide sleeve 61, a bearing seat 62 and a control component 90. The guide sleeve 61 can be variably connected to the outside of the guide rail 51. The bearing seat 62 is fixedly connected to the surface of the guide sleeve 61. The guide sleeve 61 is close to the bearing seat 62 on both sides thereof. The two pillars 63 and 64 are movably arranged. The pillars 1 63 and 64 are arranged in parallel. The pillars 1 63 and 64 are penetrated by the stretching section above the bearing seat 62 and are movably connected. The pillars 1 63 and 64 are arranged in a mirror image with the bearing seat 62. The mirror image arrangement of the pillars A limiting member 70 is disposed outside the column 1 63, wherein the limiting member 70 is controlled to rotate by the pillar 1 63. A limiting member 80 is disposed outside the pillar 2 64 arranged in a mirror image, wherein the limiting member 80 is controlled to rotate by the pillar 2 64. A control component 90 is disposed on the surface of the supporting seat 62. The control component 90 is in a linkage relationship with the pillar 2 64 and a section of the pillar 1 63 extending out of the supporting seat 62. The pillar 2 64 and the pillar 1 63 are in a reverse motion relationship. The control component 20 is movably connected to the back of the circular pad 50, and the control component 20 is linked to the guide sleeve 61.

[0050] The flange to be forged is placed on the operating panel 52. Under the action of the control component 20, the guide sleeve 61 can be linked to change its position along the guide rail 51. At this time, the limiting component 60 will gradually approach the position of the flange. The control component 90 allows the pillar 1 63 and the pillar 2 64 to rotate. At this time, the limiting member 1 70 and the limiting member 2 80 can be linked and rotated synchronously by the pillar 1 63 and the pillar 2 64. In this process, the pillar 2 64 and the pillar 1 63 are in a reverse motion relationship. The limiting member 1 70 changes to a position close to the flange. When the limiting member 60 as a whole moves along the depth of the guide rail 51, the limiting member 60 moves to the depth of the guide rail 51. The flange will gradually be centered to face the forging component during the movement. On the one hand, the flange can be forged in a precise position. On the other hand, after the flange is placed in the specified position, the staff can observe the various positions on the surface of the flange and perform a rotating action on it.

The directional seat 89 is telescopically docked with the linkage shaft 85. The directional seat 89 is surrounded by an elastic member 810. The elastic member 810 is between the hollow spline shaft 87 and the linkage When the linkage shaft 85 is adjusted to a suitable angle, the linkage cap 88 is pulled between the inner edges of the movable cap 88. At this time, the linkage cap 88 moves to a position where it is no longer connected to the hollow spline shaft 87. During this process, the linkage shaft 85 and the directional seat 89 will still maintain a distance from each other. At this time, when the linkage cap 88 rotates, the linkage shaft 85 can also be linked and rotated. The degree of each movement is 90°. Under the control of the linkage cap 88 canceling force, the directional seat 89 can make the linkage cap 88 return to the initial position. At this time, the fitting member 82 can be limited after the corresponding angle.

The arc plate 42 is located at the outer side of the bearing plate 43, and a trapezoidal block 44 is arranged on the lower end of the bearing plate 43 facing the arc plate 42, wherein both sides of the trapezoidal block 44 are inclined, so as to facilitate the movement of the wedge structure in two directions of the linkage cap 88. The number of the trapezoidal blocks 44 is the same as the number of the fitting pad 84, and a tooth pattern 45 is arranged on the back surface of the arc plate 42, and the number of the tooth pattern 45 is the same as the number of the trapezoidal blocks 44, and the spacing between a single trapezoidal block 44 is the linkage cap 88. One quarter of the total rotation speed, when the bearing frame 81 rotates, after the displacement to the specified position, the linkage cap 88 first contacts the hypotenuse of the trapezoidal block 44. At this time, under the action of the wedge-shaped fit, the linkage cap 88 can be pushed toward the outside, so that the linkage cap 88 and the hollow spline shaft 87 are no longer connected. When the plane position of the trapezoidal block 44 is reached, the linkage cap 88 engages with the tooth pattern 1 45, so that the linkage cap 88 can be rotated in conjunction with the linkage cap, thereby driving the linkage shaft 85 to rotate, so that the corresponding fitting pad 84 can be adaptively adjusted according to the specifications of the flange to act on the flange. When the linkage cap 88 corresponds to the arc plate 42, the fitting pad 84 on the bearing frame 81 is closer to the flange than the trapezoidal block 44 to avoid conflict.

The rotating shaft 24 and the guide sleeve 61 are linked through a linkage frame 25. Both ends of the linkage frame 25 are in a movable docking relationship when docked on the guide sleeve 61 and the rotating shaft 24. Under the action of the motor 21, the linkage column 22 and the linkage ring 23 will rotate. Under the action of the rotating shaft 24 and the linkage frame 25, the guide sleeve 61 can move along the guide rail 51 as a trajectory.

[0058] The present embodiment provides a flange forging method: a flange or blank after heat treatment is placed on an operating disk 52, and under the control of a motor 21, the linkage column 22 can be linked to the rotating shaft 24 and the linkage frame 25, so that the guide sleeve 61 can move toward the direction of the flange with the guide rail 51 as a trajectory, and the limiting member 1 70 acts on the surface of the flange in the shape of an "eight", and the flange can be acted on to the center position of the operating disk 52, and under the action of the guide roller 72, the angle of the flange can be adjusted, and its overall position will not change during the adjustment. After adjusting to a suitable position, the hydraulic cylinder 2 93 is driven, and the linkage frame 91 can be linked to the linkage sleeve 94 under the action of the tooth pattern 2 92, and the pillar 1 63 and the pillar 2 64 rotate in opposite directions, and the limiting member 1 70 gradually deviates from the flange, and the limiting member 2 80 will gradually approach the position of the flange, and when the bearing frame 2 81 rotates to When the trapezoidal block 44 and the arc plate 42 are in the right position, with the continuous rotation, the linkage cap 88 comes into contact with the hypotenuse of the trapezoidal block 44. At this time, under the action of the wedge-shaped cooperation, the linkage cap 88 can be pushed to the outside position. At this time, the linkage cap 88 and the hollow spline shaft 87 are not connected. When the trapezoidal block 44 is in the plane position, the linkage cap 88 is engaged with the tooth pattern 45, so that the linkage cap 88 can be rotated in conjunction with it, thereby driving the linkage shaft 85 to rotate, so that the corresponding fitting pad 84 can be adaptively adjusted according to the specifications of the flange to act on the flange. At this time, the flange is limited, and under the action of the driving hydraulic cylinder 32, the flange can be forged through the forging part 35. After forging in a single position, the hydraulic cylinder 93 can be reversed to make the limiting part 70 fit with the surface of the flange again. At this time, the flange can be adjusted in position to improve the multi-stage forging effect of the flange.

Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, without undue experimentation, the development effort will be a routine task of design, fabrication, and production.
