Description

Technical Field

[0001] The invention relates to the technical field of forging processing, and in particular to an aluminum alloy forging blank processing device and a processing method. Background Art

[0002] Aluminum alloy forging is a process that applies external force to the metal at high temperature to cause it to undergo plastic deformation to obtain the desired shape and size. During processing, the aluminum alloy billet is first surface treated and then heated, and then the heated billet is conveyed to the forging machine for forging processing to obtain the desired shape of the forged part.

[0003] During forging, since the aluminum alloy billet is heated, the die usually needs to be preheated to avoid a rapid drop in temperature during the forging process. Die preheating can reduce the temperature difference between the die and the aluminum alloy billet, prevent the generation of thermal stress, and ensure that the aluminum alloy billet is uniformly deformed during the forging process, thereby reducing the defects of the aluminum alloy material during forging and reducing the generation of forging cracks.

[0004] In the prior art, forging dies are usually preheated by adding heat medium oil inside the dies. The dies can be heated by heating the heat medium oil. However, the dies are usually made of materials with good thermal conductivity, and more heat will be lost during preheating, which can easily cause excessive energy loss. In addition, the flow of heat transfer oil may be hindered in the complex structure of the dies inside the dies. For example, in some small pipes, dead corners or narrow areas in the dies, it is difficult for the heat transfer oil to fully flow through these places, resulting in uneven heat transfer, which leads to uneven preheating of the dies surface, which may cause defects such as flow marks and silver streaks on the product surface, affecting the appearance quality of the product.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 6The present invention provides a technical solution: an aluminum alloy forging blank processing equipment, comprising a forging frame 1, a heating furnace 2 is arranged at the rear of the forging frame 1, a moving rod assembly 3 is arranged at the top and bottom of the forging frame 1, a square rod 9 is arranged on the side close to the moving rod assembly 3, a mold 4 is fixedly connected to the side close to the two square rods 9, a driving assembly 5 for driving the moving rod assembly 3 to move up and down is arranged on the right side inside the forging frame 1, a heating groove 10 is opened at the top and bottom of the forging frame 1, a heating rod 11 is fixedly connected to the inner wall of the heating groove 10, a through groove 12 is opened on the side close to the two heating grooves 10, and a heat preservation assembly 6 is arranged inside the two heating grooves 10, and the heat preservation assembly 6 includes a baffle 61 slidably connected to the position corresponding to the through groove 12 in the heating groove 10, and two baffles 61 are arranged, and the rear of the two baffles 61 The ends are fixedly connected with a movable plate 62, the inner wall of the heating groove 10 is located between the two movable plates 62 and is rotatably connected with a rotating shaft 63, the top of the outer wall of the rotating shaft 63 is fixedly connected with a gear 64, the gear 64 is only provided with a quarter of a tooth, and the bottom of the outer wall of the rotating shaft 63 is fixedly connected with a cam 65, a first spring 615 is fixedly connected between the movable plate 62 and the forging frame 1, the rear end inner wall of the heating groove 10 is fixedly connected with a sleeve plate 66, the inner wall of the sleeve plate 66 is slidably connected with a rack 67, the rack 67 is meshed with the gear 64, the front end of the rack 67 is fixedly connected with an inclined block 68, the right top of the square rod 9 is fixedly connected with an extrusion plate 69, a second spring 616 is fixedly connected between the rack 67 and the sleeve plate 66, the rear end of the extrusion plate 69 is rotatably connected with a rotating shaft 610, and a groove 611 is provided on the side where the two baffles 61 are close to each other.

[0035] By adopting the above technical solution, when in use, the aluminum alloy billet is first placed into the interior of the heating furnace 2, and the aluminum alloy billet is heated by the heating furnace 2. It should be noted that a mechanical arm is installed on the right side of the rear end between the heating furnace 2 and the forging frame 1, which is used to clamp the aluminum alloy billet heated by the heating furnace 2 between the two dies 4. Through the cooperation of the two dies 4, the aluminum alloy billet can be processed into a desired shape. During forging, the moving rod assembly 3 is driven to move by the action of the driving assembly 5, so that the two square rods 9 are close to each other, so that the two dies 4 can be closed to forge the aluminum alloy billet.

[0036] During the preheating stage of the mold 4, the driving assembly 5 is used to move the moving rod assembly 3 with the square rod 9 and the mold 4, so that the mold 4 enters the interior of the heating tank 10. During this process, the extrusion plate 69 is located above the tilting block 68 and does not squeeze the tilting block 68. At this time, the two baffles 61 are closed toward the side close to block the through groove 12 to prevent heat loss, thereby helping to reduce energy loss. Under the action of the heating rod 11 inside the heating tank 10, the air inside the heating tank 10 can be heated, so that the surface of the mold 4 is heated by the air, which makes it easier for the surface of the mold 4 to be heated evenly, thereby reducing the appearance of flow marks, silver streaks and other defects on the surface of the aluminum alloy forgings during forging, and reducing the appearance of the forgings that are affected by the quality.

[0037] The top and bottom of the front end of the tilting block 68 are tilted. When forging is performed, the driving assembly 5 causes the moving rod assembly 3 to move with the square rod 9 and the die 4 so that the two dies 4 are brought close together for forging. During this process, the extrusion plate 69 moves accordingly. When the die 4 is about to reach the position of the through groove 12, the rotating shaft 610 on the extrusion plate 69 squeezes the tilting block 68, so that the rack 67 slides inside the sleeve plate 66. Under the action of the meshing of the rack 67 and the gear 64, the rotating shaft 63 rotates, so that the cam 65 fixedly connected to the rotating shaft 63 rotates. The cam 65 used here has protrusions at both ends. As the cam 65 rotates, it is convenient for the cam 65 to approach the moving plate 62 and move the moving plate 62 Extrusion is performed, so that the two movable plates 62 move away from the two baffles 61. At this time, the baffle 61 does not block the through slot 12. When the rotating shaft 610 moves to the flat front end of the tilting block 68, the mold 4 just passes through the through slot 12. Then the moving rod assembly 3 continues to move with the mold 4, and the rotating shaft 610 moves to the tilting block 68 near the tilting part of the middle part of the forging frame 1. As the mold 4 continues to move, under the elastic force of the second spring 616, the rack 67 is reset, thereby resetting the cam 65, and under the elastic force of the first spring 615, the two baffles 61 gradually move closer and close, avoiding heat loss inside the heating tank 10 during forging. The design of the rotating shaft 610 is conducive to reducing the friction of movement.

[0038] When the moving rod assembly 3 continues to carry the mold 4 back to the heating tank 10, when the mold 4 moves to near the through groove 12, the rotating shaft 610 on the extrusion plate 69 squeezes the inclined portion of the tilting block 68 near the middle part of the forging frame 1, and with the cooperation of the rack 67, the gear 64 and the cam 65, the two moving plates 62 carry the two baffles 61 away from each other without blocking the through groove 12, so that the mold 4 can return to the interior of the heating tank 10 through the through groove 12, and as the moving rod assembly 3 continues to move until the extrusion plate 69 is located above the tilting block 68, the two baffles 61 close together, thereby closing the through groove 12 to achieve a heat preservation effect.

[0039] It should be noted that teeth are provided on a quarter of the outer side of the gear 64 , so that when the gear 64 rotates a quarter of a circle, the cam 65 completes squeezing the movable plate 62 , so that the two baffles 61 move away from each other and the baffles 61 do not block the through slot 12 .

[0040] Specifically, Figure 2 , Figure 3 and Figure 7 As shown, the inner sides of the two grooves 611 that are away from each other are fixedly connected with a folded corrugated plate 612, the outer sides of the folded corrugated plate 612 are fixedly connected with a first sealing gasket 613, and the sides of the two baffles 61 that are close to each other are fixedly connected with a second sealing gasket 614.

[0041] By adopting the above technical solution, the first sealing gasket 613 and the second sealing gasket 614 are made of high-temperature resistant rubber material. During preheating, when the two baffles 61 are in a closed state, under the action of the elastic force of the folded corrugated plates 612 themselves, the first sealing gaskets 613 on the two folded corrugated plates 612 are in contact with each other on one side, and the two second sealing gaskets 614 are in contact with each other, which has a good heat preservation effect.

[0042] During forging, as the two baffles 61 are closed, the square rod 9 is located inside the groove 611, and the folded corrugated plate 612 can shrink to ensure that the square rod 9 can enter the inside of the groove 611. At this time, the first sealing gasket 613 on the folded corrugated plate 612 is close to the square rod 9 and contacts the square rod 9 to achieve a better heat preservation effect.

[0043] It should be noted that when the folded corrugated plate 612 itself expands and contracts, the front and rear end portions of the first sealing gasket 613 can fit the inner wall of the groove 611, further improving the heat preservation effect.

[0044] Specifically, Figure 2 , Figure 3 and Figure 6 As shown, the moving rod assembly 3 includes a lifting rod 31 slidably connected to the middle part of the forging frame 1, the lifting rod 31 is rotatably connected to a round shaft 32 on the side close to the square rod 9, the round shaft 32 is fixedly connected to the square rod 9 on the side close to the square rod 9, the outer side of the round shaft 32 is threadedly connected to a moving ring 33, the outer wall of the round shaft 32 is fixedly connected to a first magnetic ring 34 on the side close to the square rod 9, the moving ring 33 is fixedly connected to a second magnetic ring 35 on the side close to the square rod 9, the first magnetic ring 34 and the second magnetic ring 35 are close to each other on the side with the same magnetic poles, and the moving ring 33 is fixedly connected to an anti-slip ring 36 on the side away from the square rod 9.

[0045] By adopting the above technical solution, during preheating, the lifting rod 31 is moved by the driving component 5, so that the round shaft 32, the square rod 9 and the mold 4 are moved, and the mold 4 is moved to the inside of the heating groove 10 and is located in an area away from the through groove 12, until the side of the moving ring 33 away from the square rod 9 and the anti-slip ring 36 contact the inner wall of the heating groove 10. At this time, the driving component 5 drives the lifting rod 31 to reciprocate slightly, so that the distance between the moving ring 33 and the round shaft 32 changes, and under the action of the threaded connection, the round shaft 32, the square rod 9 and the mold 4 are rotated, so that the mold 4 is evenly heated, thereby improving the uniformity of preheating of the surface of the mold 4.

[0046] It should be noted that when the side of the movable ring 33 away from the square rod 9 and the anti-slip ring 36 contact the inner wall of the heating groove 10, when the lifting rod 31 continues to be moved away from the square rod 9, the movable ring 33 is limited by the forging frame 1, and the distance between the movable ring 33 and the round shaft 32 changes, so that the round shaft 32 can rotate with the square rod 9 and the mold 4. When the lifting rod 31 is moved toward the square rod 9, the magnetic repulsion of the first magnetic ring 34 and the second magnetic ring 35 facilitates the reset of the movable ring 33.

[0047] It should be noted that a thread is provided on the surface of the circular shaft 32, and the pitch of the thread is relatively large, which is conducive to reducing the friction of movement. The connection method between the movable ring 33 and the circular shaft 32 is similar to the connection method between the screw part and the flying saucer part of a hand-propelled flying saucer, so as to ensure that when the movable ring 33 and the circular shaft 32 move relative to each other, part of the circular shaft 32 can rotate.

[0048] It should be noted that when the movable ring 33 is not limited by the forging frame 1, it is repelled by the magnetic force, so that the side of the movable ring 33 away from the square rod 9 is in contact with the surface of the lifting rod 31. At this time, the positions of the square rod 9 and the extrusion plate 69 return to the initial angle.

[0049] Specifically, Figure 2 , Figure 3 and Figure 6 As shown, the outer top of the square rod 9 is located above the extrusion plate 69 and is fixedly connected with a stirring blade 7.

[0050] By adopting the above technical solution, as the square rod 9 rotates, the agitator blades 7 can mix the air in the heating tank 10, further improving the uniformity of heating, thereby further improving the uniformity of preheating the surface of the mold 4.

[0051] Specifically, Figures 1 to 3As shown, the driving assembly 5 includes a double-headed motor 51 fixedly connected to the middle right side of the forging frame 1, the output shafts at the top and bottom ends of the double-headed motor 51 are fixedly connected to the screw rod 52, the surface of the screw rod 52 is threadedly connected to the lifting plate 53, the two sides of the lifting plates 53 close to each other are fixedly connected to the lifting rod 31, the top and bottom ends of the forging frame 1 are fixedly connected to the fixed cover 13, the lifting plate 53 is inside the fixed cover 13, and the right side of the lifting plate 53 is slidably connected to the inner wall of the fixed cover 13.

[0052] By adopting the above technical solution, it should be noted that the aluminum alloy billet required for forging in this device is a thinner material, and the motor adopts a three-phase double-headed motor with sufficiently large torque to ensure that the force provided is sufficient to complete the forging and can control the number of turns of the steering gear.

[0053] When the lifting rod 31 needs to be driven to move, the output shaft of the double-headed motor 51 rotates to rotate the screw rod 52, thereby causing the lifting plate 53 to move up and down to control the movement of the lifting rod 31. The design of the fixed cover 13 prevents the screw rod 52 from being partially exposed.

[0054] It should be noted that the forging frame 1 and the heating furnace 2 of this solution are fixedly installed through external metal.

[0055] Specifically, Figures 1 to 4 and Figure 8 As shown, an anti-oxidation component 8 is provided on the inner right side portion of the forging frame 1, and the anti-oxidation component 8 includes a wind hood 81 fixedly connected to the inner side of the middle portion of the forging frame 1, and an air inlet pipe 82 is fixedly inserted at both the top and bottom ends of the wind hood 81, and the end of the air inlet pipe 82 away from the wind hood 81 passes through the forging frame 1, and the middle portion of the air inlet pipe 82 penetrates the portion of the forging frame 1 close to the heating tank 10, and a plurality of ejection holes 83 are opened on the left side of the wind hood 81.

[0056] By adopting the above technical solution, it should be noted that nitrogen can be introduced from the outer end of the air inlet pipe 82, and the nitrogen enters the wind cover 81 and is ejected from the ejection hole 83, so as to avoid the formation of an oxide film on the aluminum alloy billet and cause cracks during forging.

[0057] It should be noted that the hood 81 is designed to be longer, so that nitrogen can be input into the forging frame 1 and the area between the heating furnace 2 and the forging frame 1, so that nitrogen can be transported during the transportation of heated billets and forging, thereby reducing the generation of oxide film.

[0058] It should be noted that, since the middle portion of the air inlet pipe 82 penetrates into the portion of the forging frame 1 close to the heating tank 10, the nitrogen can be preheated to prevent the nitrogen from seriously affecting the temperature of the blank.

[0059] A processing method of aluminum alloy forging blank processing equipment comprises the following steps:

[0060] S1, heating, placing the blank into a heating furnace 2 for heating;

[0061] S2. The die 4 is preheated, and the blank is placed in the forging frame 1 for forging.

[0062] Working principle: firstly, the aluminum alloy billet is placed into the interior of the heating furnace 2, and the aluminum alloy billet is heated by the heating furnace 2, and the aluminum alloy billet heated by the heating furnace 2 is clamped between the two molds 4. Through the cooperation of the two molds 4, the aluminum alloy billet can be processed into a desired shape. In the preheating stage of the mold 4, the moving rod assembly 3 is moved with the square rod 9 and the mold 4 through the action of the driving assembly 5, so that the mold 4 enters the interior of the heating tank 10. During this process, the extrusion plate 69 is located above the tilting block 68, and the tilting block 68 is not extruded. At this time, the two baffles 61 are closed toward the side close to each other, which can block the through groove 12 to avoid heat loss, thereby helping to reduce energy loss. Under the action of the heating rod 11 inside the heating tank 10, the air inside the heating tank 10 can be heated, so that the surface of the mold 4 is heated by the air, so that the surface of the mold 4 is evenly heated, thereby reducing the appearance of flow marks, silver streaks and other defects on the surface of the aluminum alloy forgings during forging, and reducing the appearance of the forgings. The quality is affected.

[0063] The first sealing gasket 613 and the second sealing gasket 614 are made of high temperature resistant rubber material. During preheating, when the two baffles 61 are in a closed state, under the action of the elastic force of the folded corrugated plates 612 themselves, the first sealing gaskets 613 on the two folded corrugated plates 612 are in contact with each other on one side, and the two second sealing gaskets 614 are in close contact with each other, which has a good heat preservation effect.

[0064] During preheating, the lifting rod 31 is moved by the driving assembly 5, so that the round shaft 32, the square rod 9 and the mold 4 are moved, and the mold 4 is moved to the inside of the heating tank 10 and is located in an area away from the through groove 12, until the side of the moving ring 33 away from the square rod 9 and the anti-slip ring 36 contact the inner wall of the heating tank 10. At this time, the lifting rod 31 is driven by the driving assembly 5 to reciprocate slightly, so that the distance between the moving ring 33 and the round shaft 32 changes, and under the action of the threaded connection, the mold 4 is rotated so that the mold 4 is evenly heated, thereby improving the uniformity of preheating of the surface of the mold 4. The agitator blade 7 can mix the air in the heating tank 10 to further improve the uniformity of heating, thereby further improving the uniformity of preheating of the surface of the mold 4. Nitrogen can be introduced from the outer end of the air inlet pipe 82, and the nitrogen enters the wind cover 81 and is ejected from the ejection hole 83 to prevent the aluminum alloy billet from forming an oxide film and causing cracks during forging.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
