Description

Technical Field

[0001] This invention relates to the field of aluminum forging manufacturing, and in particular to an aluminum forging press and forging method. Background Technology

[0002] Aluminum forgings are components manufactured from aluminum alloy billets through a forging process. They possess advantages such as high strength, lightweight, and corrosion resistance, and are widely used in aerospace, automotive, and rail transportation industries. Their core value lies in eliminating internal defects in the material through forging, improving mechanical properties, and meeting the demands for high precision and reliability. During the forging process, aluminum alloy billets typically need to be flipped; however, due to the high temperature of the billets at this stage, flipping is not always convenient. Summary of the Invention

[0003] This invention provides an aluminum forging press and forging method, which facilitates the flipping of aluminum alloy billets during forging.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] An aluminum forging press includes an anvil and a hammer seat. Vertical sliding rods are fixed at the four corners of the anvil, and a hydraulic mechanism is fixed at the upper end of the vertical sliding rods. The hammer seat slides through the four vertical sliding rods and is fixedly connected to the lower end of the hydraulic mechanism. A semi-circular groove is provided in the front-back direction at the upper end of the anvil, and a semi-circular seat is rotatably fitted in the semi-circular groove.

[0006] The anvil has a through hole at the bottom of the upper semicircular seat, and a horizontal seat slides in the through hole. Fork plates are fixed at both ends of the horizontal seat. Protruding pins are symmetrically fixed at the eccentric ends of the two semicircular seats, and the two protruding pins slide in the elongated holes of the two fork plates respectively.

[0007] A threaded rod is rotatably threaded through the anvil, and the threaded rod is threadedly connected to the cross seat.

[0008] Both ends of the anvil are fixed with sliding rod frames, and two push plate frames slide on the two sliding rod frames, which slide against the upper surface of the anvil.

[0009] The hydraulic mechanism is fixed with electric telescopic rods at both ends. The lower ends of the two electric telescopic rods are fixed with lifting frames. The two lifting frames slide through the corresponding two vertical sliding rods. The two lifting frames are connected to the corresponding push plate frames by a linkage plate.

[0010] The hammer base has a mounting groove at the lower center, and a hammer block is installed in the mounting groove through a horizontal shaft.

[0011] The hammer block includes a base sleeve fitted on a horizontal axis, with a flat seat on one side of the base sleeve and a cutter on the other side of the base sleeve.

[0012] Both the planar seat and the cutter are provided with limiting through holes, and the lower parts of the left and right sides of the hammer seat are provided with sliding limiting shafts.

[0013] Both ends of the horizontal shaft are fixed with side brackets, and a bidirectional screw rotates between the two side brackets. The outer ends of the two limiting shafts are fixed with threaded seats, and the two threaded seats are respectively threaded to the two ends of the bidirectional screw.

[0014] The forging method using the aforementioned aluminum forging press includes:

[0015] S1. Make the plane of the semicircular base and the upper end face of the anvil lie in the same plane;

[0016] S2. Place the aluminum alloy billet on the upper surface of the semi-circular seat and the anvil seat, and control the hammer seat to slide down through the hydraulic mechanism to form a forging of the aluminum alloy billet.

[0017] S3. Control the semicircular seat to rotate on the anvil, so that the upper end face of the anvil and the plane of the semicircular seat form a height difference. Use this height difference to flip the aluminum alloy billet, and then rotate the semicircular seat back to perform forging again.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. By rotating the semi-circular seat on the anvil, a height difference is formed between the upper end face of the anvil and the plane of the semi-circular seat, thereby turning the aluminum alloy billet over, so as to facilitate the turning of the aluminum alloy billet during forging.

[0020] 2. By rotating the base sleeve on the horizontal axis, the switch between the flat seat and the cutter can be realized. Attached Figure Description

[0037] like Figure 1-9 As shown, a detailed description of an aluminum forging press is provided:

[0038] An aluminum forging press includes an anvil 101 and a hammer seat 201. Vertical slide rods 104 are fixed at the four corners of the anvil 101. A hydraulic mechanism 105 is fixed at the upper end of the vertical slide rods 104. The hammer seat 201 slides through the four vertical slide rods 104 and is fixedly connected to the lower end of the hydraulic mechanism 105. A semi-circular groove 102 is provided in the front-back direction at the upper end of the anvil 101. A semi-circular seat 501 is rotatably fitted in the semi-circular groove 102.

[0039] During forging, first control the plane of the semicircular seat 501 and the upper end face of the anvil 101 to be at the same level. Place the aluminum alloy billet on the upper end face of the semicircular seat 501 and the anvil 101. Control the hammer seat 201 to slide up and down the four vertical slide bars 104 through the hydraulic mechanism 105, so that the hammer seat 201 descends and forms forging of the aluminum alloy billet.

[0040] When the aluminum alloy billet needs to be flipped, the semicircular seat 501 is controlled to rotate on the anvil 101. The rotation of the semicircular seat 501 will cause its plane to tilt, resulting in one end of the plane being higher than the anvil 101 and the other end being lower than the anvil 101. A height difference is formed relative to the semicircular seat 501 plane at the end lower than the anvil 101. While the aluminum alloy billet is supported by the anvil 101, it loses the support of the semicircular seat 501 plane, causing the aluminum alloy billet to tilt towards the plane of the semicircular seat 501 under its own weight, so that the aluminum alloy billet automatically completes the flipping. When the plane of the semicircular seat 501 returns to horizontal, the aluminum alloy billet completes a 90° flip.

[0041] The hydraulic mechanism 105 includes a hydraulic cylinder and a hydraulic system for controlling the extension and retraction of the hydraulic cylinder, thereby controlling the lifting and lowering of the hammer base 201 through the hydraulic cylinder.

[0042] Further:

[0043] The anvil 101 has a through hole 103 below the semi-circular seat 501. A horizontal seat 503 slides in the through hole 103. Fork plates 504 are fixed at both ends of the horizontal seat 503. Protruding pins 502 are symmetrically fixed at the eccentric ends of the semi-circular seat 501. The two protruding pins 502 slide in the elongated holes of the two fork plates 504 respectively.

[0044] By controlling the horizontal seat 503 to move left and right in the through hole 103, the two fork plates 504 can be moved left and right. Then, the protruding pin 502 is pushed through the elongated hole of the fork plate 504, so that the protruding pin 502 drives the semicircular seat 501 to rotate in the semicircular groove 102, thereby achieving smooth control of the rotation of the semicircular seat 501.

[0045] When the semicircular seat 501 is rotated by pushing the protruding pin 502, the semicircular seat 501 will not slide out of the semicircular groove 102 because of its large weight.

[0046] Further:

[0047] A threaded rod 505 is rotatably inserted through the anvil 101, and the threaded rod 505 is threadedly connected to the cross seat 503.

[0048] The first motor installed on the anvil 101 drives the threaded rod 505 to rotate, and then through the threaded engagement between the threaded rod 505 and the cross seat 503, automatic and smooth control of the cross seat 503 moving left and right in the through hole 103 is formed.

[0049] Furthermore, the threaded engagement between the threaded rod 505 and the horizontal seat 503 can lock the state of the semicircular seat 501, ensuring that the semicircular seat 501 remains stationary when its plane is horizontal, thus guaranteeing the forging effect.

[0050] Further:

[0051] Both ends of the anvil 101 are fixed with slide rod brackets 106, and two push plate brackets 602 slide on the two slide rod brackets 106. The two push plate brackets 602 slide against the upper surface of the anvil 101.

[0052] By sliding the push plate frame 602 on the slide bar frame 106, the push plate frame 602 is restricted from moving on the upper end face of the anvil 101, thus creating a push on the aluminum alloy billet in the left and right directions. Subsequently, when the aluminum alloy billet is flipped, the position of the aluminum alloy billet can be controlled to ensure that part of the aluminum alloy billet is located on the anvil 101 and part is located on the semi-circular seat 501, ensuring that the aluminum alloy billet can be flipped when the semi-circular seat 501 rotates.

[0053] Further:

[0054] The hydraulic mechanism 105 has electric telescopic rods 107 fixed at both ends. The lower ends of the two electric telescopic rods 107 are fixed with lifting frames 601. The two lifting frames 601 slide through the corresponding two vertical sliding rods 104. The two lifting frames 601 are connected by a linkage plate 603 that rotates between them and the corresponding push plate frame 602.

[0055] Further:

[0056] The hammer base 201 has a mounting groove 202 at the lower middle part, and a hammer block is installed in the mounting groove 202 through a horizontal shaft 401.

[0057] The hammer block is installed in the mounting groove 202 at the lower end of the hammer seat 201 via the horizontal shaft 401. This allows the hammer block to be replaced by disassembling the horizontal shaft 401, thus facilitating the replacement of the hammer block. Consequently, the forging press can use hammer blocks of different shapes to adapt to the forging process of forgings under different conditions.

[0058] Further:

[0059] The hammer block includes a base sleeve 301 fitted on a horizontal shaft 401. A flat seat 302 is provided on one side of the base sleeve 301, and a cutter 303 is provided on the other side of the base sleeve 301.

[0060] By rotating the base sleeve 301 on the horizontal axis 401, the position of the flat seat 302 or the cutter 303 can be adjusted to be below, thereby completing the flat forging or cutting process.

[0061] Further:

[0062] Both the planar seat 302 and the cutter 303 are provided with limiting through holes 304, and the lower parts of the left and right sides of the hammer seat 201 are provided with sliding limiting shafts 405.

[0063] In order to ensure the relative stability between the hammer block and the horizontal axis 401, the limiting shaft 405 is inserted into the corresponding limiting through hole 304, thereby limiting the hammer block and ensuring stable operation when the flat seat 302 or the cutter 303 is processing.

[0064] Further:

[0065] Both ends of the horizontal shaft 401 are fixed with side brackets 402, and a bidirectional screw 403 rotates between the two side brackets 402. The outer ends of the two limiting shafts 405 are fixed with threaded seats 404, and the two threaded seats 404 are respectively threaded to both ends of the bidirectional screw 403.

[0066] By rotating the bidirectional screw 403, the opposite threads at both ends of the bidirectional screw 403 will drive the two threaded seats 404, causing the two threaded seats 404 to move closer or further away synchronously within the two side brackets 402, which in turn drives the two limiting shafts 405 to move closer or further away synchronously, thereby controlling the two limiting shafts 405 to simultaneously insert into or slide out of the two ends of the limiting through hole 304, thus improving the efficiency of controlling the two limiting shafts 405.

[0067] The two side frames 402 are fixedly connected to the two end faces of the horizontal shaft 401 by screws, forming an axial limit on the horizontal shaft 401. At the same time, the two side frames 402 are also fixedly connected to the two ends of the hammer seat 201 by bolts, forming a circumferential limit on the horizontal shaft 401.

[0068] like Figure 1-9 As shown, a forging method for an aluminum forging press is described in detail:

[0069] The forging method using the aforementioned aluminum forging press includes:

[0070] S1. Make the plane of the semicircular seat 501 and the upper end face of the anvil 101 in the same plane;

[0071] S2. Place the aluminum alloy billet on the upper surfaces of the semi-circular seat 501 and the anvil seat 101, and control the hammer seat 201 to slide down through the hydraulic mechanism 105 to form a forging of the aluminum alloy billet.

[0072] S3. Control the semicircular seat 501 to rotate on the anvil 101. The rotation of the semicircular seat 501 will tilt its plane, so that one end of the plane is higher than the anvil 101 and the other end is lower than the anvil 101, so that the upper end surface of the anvil 101 and the plane of the semicircular seat 501 form a height difference. Using this height difference, the aluminum alloy billet is tilted towards the plane of the semicircular seat 501 under the influence of its own gravity, so that the aluminum alloy billet automatically completes the flipping. Then the semicircular seat 501 is rotated back and forging is performed again.
