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 common metal processing method that heats the metal blank to a high temperature to make it plastic and suitable for forging. Usually, forging blanks are used and appropriate blank shapes are designed according to the flange type and specifications.

[0003] When metal parts are heated, the iron oxide on the surface will form an oxide covering layer. However, the pressure and stress applied during the forging process may cause the structural layer between the iron oxide and the underlying metal matrix to separate. This separation is usually called "scaling". If these iron oxide scales are not cleaned in time, they will not only affect the quality of subsequent processing, but may also cause equipment wear and even pose a safety hazard. Traditional methods usually require stopping the machine for manual cleaning, which increases downtime and reduces production efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0031] Example

[0032] like Figure 1 As shown, Figure 1 The figure shows the overall front view of the forging device in the embodiment;

[0035] like Figure 2 、 Figure 3 As shown, Figure 2 The figure shows a partial cross-sectional view of the forging device in the embodiment. Figure 1 ; Figure 3 What is shown is a top view of the workbench in the embodiment;

[0036] An equipment cavity is provided inside the workbench 10 , and a reversible carrying plate 20 is provided inside the workbench 10 . Limiting blocks 21 are provided on both end surfaces of the carrying plate 20 . A limiting groove is provided on the limiting block 21 , and the limiting groove corresponds to the position of the punching head 12 .

[0037] The function of the limiting block 21 and the limiting groove is to fix the flange to be processed, and the function of the hydraulic cylinder 13 is to provide power so that the punch head 12 can move longitudinally to complete the forging process.

[0038] The two end faces of the carrier plate 20 are Figure 2 The a and b end faces shown in FIG, the flip-over carrying plate 20 can realize fast unloading, such as Figure 1 As shown, a material taking hole communicating with the inner cavity is provided on the front side of the workbench 10 .

[0039] Specifically, a motor 22 is further provided on the outside of the workbench 10 , a rotating shaft that rotates with the workbench 10 is passed through the supporting plate 20 , and an output end of the motor 22 is fixedly connected to one end of the rotating shaft.

[0040] The rotating shaft and the motor 22 are used to realize the flipping operation of the supporting plate 20 .

[0041] like Figure 2 、 Figure 4 As shown, Figure 2 The figure shows a partial cross-sectional view of the forging device in the embodiment. Figure 1 ; Figure 4 The figure shows a partial cross-sectional view of the forging device in the embodiment. Figure 2 ;

[0042] Support boxes 30 are also movably provided on both sides of the workbench 10 in the horizontal direction. The support box 30 moves to the bottom of the carrier plate 20 or away from the bottom of the carrier plate 20. When the support box 30 moves to the bottom of the carrier plate 20, its top end contacts the carrier plate 20. When the support box 30 moves away from the carrier plate 20, the carrier plate 20 can be freely flipped.

[0043] Figure 2The figure shows the state where the support box 30 is away from the carrier plate 20. At this time, the carrier plate 20 can be turned over freely to switch different end faces for use;

[0044] Figure 4 The figure shows the state where the support box 30 moves to the bottom of the carrier plate 20, and the top of the support box 30 contacts the carrier plate 20. At this time, the support box 30 plays a supporting role to prevent the carrier plate 20 from being displaced or deformed during the stamping process, thereby ensuring the stability of the forging process.

[0045] Specifically, the top of the support box 30 is open, and a plurality of partition plates 31 are provided inside the support box 30;

[0046] The support box 30 can collect the iron oxide produced during the forging process and attached to the front working end surface of the support plate 20. The top end surfaces of the multiple partition plates 31 are flush and in contact with the bottom of the support plate 20, which further improves the supporting force.

[0047] Specifically, an electric telescopic rod 32 is provided on the side wall inside the workbench 10, and the output end of the electric telescopic rod 32 is connected to the support box 30 on the side;

[0048] The output end of the electric telescopic rod 32 is provided with a magnet 1 33, and the end of the support box 30 close to the electric telescopic rod 32 is provided with a magnet 2 34. The magnet 1 33 and the magnet 2 34 are attracted to each other and can be separated under the action of an external force;

[0049] The horizontal movement of the support box 30 is driven by the electric telescopic rod 32 , and the detachable connection between the support box 30 and the electric telescopic rod 32 is achieved through the attraction between the magnet 1 33 and the magnet 2 34 .

[0050] like Figure 4 、 Figure 5 、 Figure 6 As shown, Figure 4 The figure shows a partial cross-sectional view of the forging device in the embodiment. Figure 2 ; Figure 5 Shown is Figure 4 A schematic diagram of the structure at center A; Figure 6 Shown is a schematic top view of the vibration assembly;

[0051] Also includes a vibration component,

[0052] The vibration assembly includes a fixed plate 41 disposed inside the workbench 10 and near the supporting plate 20. A horizontal auxiliary rod 42 is inserted into the fixed plate 41. An auxiliary plate 43 is provided at one end of the auxiliary rod 42 away from the fixed plate 41. A spring 44 is sleeved on a section of the auxiliary rod 42 located outside the fixed plate 41 and between the auxiliary plate 43. A mounting shaft 46 is also rotatably inserted into the workbench 10. A cam 48 is provided on the mounting shaft 46 at a position corresponding to the auxiliary plate 43. The working end of the cam 48 is always in contact with the auxiliary plate 43.

[0053] The vibration assembly further includes a toothed plate 45 disposed on the side wall of the support box 30, and a gear 47 that can mesh with the toothed plate 45 is disposed on the mounting shaft 46 at a position corresponding to the toothed plate 45;

[0054] During the horizontal movement of the support box 30, its tooth plate 45 engages with the gear 47 to drive the gear 47 to rotate, and the rotation of the gear 47 drives the mounting shaft 46 to rotate, thereby driving the cam 48 to rotate. During the rotation of the cam 48, its long axis end and the short axis end alternately contact the auxiliary plate 43 to drive the auxiliary rod 42 to intermittently touch and knock the carrier plate 20, so that the iron oxide attached to the lower end face of the carrier plate 20 falls off, so as to facilitate the cleanliness of the next round by flipping the carrier plate 20 so that the end face faces upward as the working end face.

[0055] The vibration of the supporting plate 20 helps to loosen and shake off impurities such as iron oxide attached to its surface, causing them to fall into the support box 30 below for collection, thereby avoiding the tedious steps of manual cleaning, improving work efficiency, and ensuring the quality of subsequent processing by effectively removing iron oxide. At the same time, it also reduces the risk of equipment wear or failure caused by residues, thereby extending the service life of the equipment.

[0056] Working principle: When the device is in use, in the initial state, the carrier plate 20 is in a horizontal state, with any end surface facing upward. At this time, the support box 30 is located below the carrier plate 20 to provide additional support for the carrier plate 20. During forging, the hydraulic cylinder 13 is activated to drive the punch head 12 to move longitudinally to forge the flange placed in the limit groove of the limit block 21;

[0057] When one forging is completed, the electric telescopic rod 32 is started to move the support box 30 away from under the carrier plate 20, and then the motor 22 is started to flip the carrier plate 20 to achieve rapid unloading of the forged flange. At this time, the other end face of the carrier plate 20 is switched to face upwards.

[0058] Before the next forging operation, the electric telescopic rod 32 is activated to move the support box 30 again below the carrier plate 20. During the movement of the support box 30, the toothed plate 45 on its side wall engages with the gear 47 on the mounting shaft 46, driving the gear 47 to rotate. The rotation of the gear 47 causes the mounting shaft 46 and the cam 48 to rotate together. The long and short ends of the cam 48 alternately contact the auxiliary plate 43, causing the auxiliary plate 43 to produce intermittent left and right movement. This vibration is then transmitted to the carrier plate 20 through the auxiliary rod 42, causing the carrier plate 20 to vibrate. The vibration of the carrier plate 20 causes the iron oxide attached to the surface of the previous working end face (the lower end face) to fall off and fall into the support box 30 below.

[0059] Also included is a flange forging method, which uses the above-mentioned flange forging device and includes the following steps:

[0060] S1. Adjust the carrying plate 20 to a horizontal position: The carrying plate 20 is in a horizontal state, and the support box 30 is located below the carrying plate 20 to provide additional support for the carrying plate 20;

[0061] S2. Flip the carrier plate 20 to prepare for the next forging: After one forging is completed, the support box 30 is removed from under the carrier plate 20, and the carrier plate 20 is flipped so that the other end surface of the carrier plate 20 faces upward;

[0062] S3, the support box 30 is reset and the gear drive is started: the support box 30 moves again to the bottom of the carrier plate 20. During the movement of the support box 30, the toothed plate 45 on the side wall thereof engages with the gear 47 on the mounting shaft 46, driving the gear 47 to rotate;

[0063] S4. Gear 47 rotates to drive the cam mechanism: The rotation of gear 47 causes the mounting shaft 46 and cam 48 to rotate together. The long axis end and the short axis end of cam 48 alternately contact the auxiliary plate 43, causing the auxiliary plate 43 to produce intermittent left and right movement;

[0064] S5. The auxiliary plate 43 knocks and removes the iron oxide: the auxiliary plate 43 knocks the supporting plate 20 to remove the iron oxide attached to the lower end surface thereof.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
