The set range of the up-and-down sliding can be designed and selected according to requirements, and the set range can only cover the contact position of the upper anvil, the tube plate blank and the lower anvil and the separation position of the tube plate blank and the lower anvil after the upper anvil is removed.
At least two elastic supporting bodies are arranged on the base 8 and respectively support the two supporting rollers 3 so as to lift the tube plate 2 blank out of contact with the lower anvil 4 after the upper anvil 1 is removed, and when the upper anvil 1 acts on the tube plate 2 blank, the elastic supporting bodies of the tube plate 2 blank compress to enable the tube plate 2 blank to move downwards to be in contact with the lower anvil 4.
In an embodiment of the present invention, two ends of the supporting roller 3 are respectively rotatably installed on the corresponding supporting seat 6, each supporting seat 6 is slidably installed on the base 8 along the vertical direction, the elastic supporting body is disposed at the lower portion of the supporting seat 6, and the two ends are respectively abutted against the supporting seat 6 and the base 8. The manner of the rotational mounting is not limited, but the rotational mounting is realized by using the bearing 5 in the present embodiment. The outer ring of the bearing 5 is embedded on the supporting seat 6, and the inner ring is sleeved on the supporting roller 3.
The utility model discloses an in the embodiment, be provided with on the base 8 with the recess 9 that supporting seat 6 matches, supporting seat 6 clamps in the recess 9, and follow the lateral wall of recess 9 slides from top to bottom. The bottom of the groove 9 is provided with a mounting hole 10 matched with the elastic support body, the height of the elastic support body is larger than the depth of the mounting hole 10, the compression direction of the elastic support body is arranged along the vertical direction, the elastic support body is installed in the mounting hole 10, and two ends of the elastic support body are respectively abutted against the bottom wall of the mounting hole 10 and the bottom of the supporting seat 6. The elastic support body can be any type of component capable of storing energy in a compressed state and transferring or transferring the energy when restoring the deformation, including but not limited to a bent reed, a spring, or a block of polymer material with good elasticity, and preferably, the elastic support body in this embodiment is a spring 7 in consideration of manufacturing cost and versatility. The spring 7 is arranged in a mounting hole 10 in a groove 9 of the base 8, the supporting seat 6 is arranged in the groove 9 above the spring 7, when the forging application force is exerted, the acting force is larger than the supporting force of the spring when the upper anvil acts on the tube plate blank, the tube plate blank moves downwards to be in contact with the lower anvil, so that under the extrusion of the upper anvil and the lower anvil, the forging part at the edge of the tube plate flows towards two sides to form a corresponding bulge, when the forging at the position is completed, the upper anvil is removed, the spring restores to deform to support the tube plate blank away from the lower anvil, and the tube plate blank can be rotated to another forging position under the supporting and assisting of the supporting roller. It will be appreciated by those skilled in the art that the common force of all the resilient supports when they return to deformation should be greater than the weight of all the support rollers, all the support seats and the tube sheet blank.
In an embodiment of the present invention, each of the supporting seats 6 is supported by two elastic supporting bodies, and two elastic supporting bodies are respectively disposed on two sides of the rotating shaft of the supporting roller 3. The arrangement can ensure that the stress of the springs 7 on two sides of each supporting seat 6 is uniform, and is also beneficial to keeping higher stability of the supporting seats 6.
In an embodiment of the present invention, the distance between the two axes of the supporting rollers 3 is 0.5 to 0.8 times the diameter of the blank of the tube plate 2 to be supported, and the support is more stable in this range.
In an embodiment of the present invention, the supporting roller 3 is a cylinder, and the length of the supporting roller is greater than the maximum thickness of the flange tube plate 2 formed by the blank of the tube plate 2. So that the tube plate 2 cannot be clamped between the two support seats 6 and cannot rotate.
In an embodiment of the present invention, the base 8 is a cuboid, and the length and the width are both greater than the length of the supporting roller 3. The pressure of the supporting roller 3 can be fully pressed on the base 8, and the base 8 can more reliably support the supporting roller 3.
Referring to fig. 1, when the steel ingot is heated to 1150 ℃ to 1250 ℃, as shown in fig. 2, a discoid tube plate 2 with a certain diameter and thickness is preliminarily forged, and the discoid tube plate 2 is clamped by an operating machine, and the discoid tube plate 2 is stood on the tool for forging the flanged tube plate 2 as shown in fig. 1. The cake-shaped tube plate 2 stands on the two supporting rollers 3, and the supporting seat 6 prevents the cake-shaped tube plate 2 from inclining. After the downward pressure is applied to the round cake-shaped tube plate 2, the supporting roller 3 presses the spring 7 to contract, the height of the supporting roller 3 is reduced, and the round cake-shaped tube plate 2 is pressed on the lower anvil 4. The upper anvil 1 rolls down the edge of the tube sheet 2 so that the edge of the tube sheet 2 in the thickness direction is protruded. After the edge projection has been reached, the pressing force is no longer applied to the tube sheet 2, so that the springs 7 spring up and the tube sheet 2 is not pressed against the lower anvil 4, but rather against the two supporting rollers 3. The two ends of the supporting roller 3 are connected in the inner ring of the bearing 5 and thus fixed to the support 6. The tube plate 2 is pressed on the supporting roller 3, the tube plate 2 is clamped by the manipulator, the tube plate 2 is rotated, and the tube plate 2 can be easily rotated successfully due to the supporting roller 3. Then rolling the edge part without the projection, and continuing to rotate after the rolling is finished. This procedure is repeated all the time. Until the edge of the tube sheet 2 is pressed all the way out to form a flanged tube sheet 2 as shown in fig. 5.
The utility model relates to a take forging instrument of flange tube sheet has simple structure, and the material is easy, easily makes, and convenient operation sparingly forges the beneficial effect of raw and other materials. Therefore, the utility model discloses thereby effectively overcome some practical problems among the prior art and had very high use value and use meaning. The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
