DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0036] Example 1

[0037] See also Figure 1-9 ,

[0038] A forging equipment for titanium alloy processing includes a quenching box 1, a flow pump body 3 and a placement frame 4. The quenching box 1 is provided with quenching liquid, and the placement frame 4 is used to place the titanium alloy parts that need to be quenched. The flow pump body 3 is arranged directly below the placement frame 4. The flow pump body 3 can accelerate the movement of the quenching liquid toward the placement frame 4, so that the quenching liquid can circulate in the quenching box 1, thereby improving the quenching quality of the titanium alloy parts.

[0039] A hydraulic cylinder 2 is fixedly connected to the quenching box 1, an output end of the hydraulic cylinder 2 is connected to an output shaft, a bottom end of the output shaft is connected to a placement frame 4, and the placement frame 4 is driven to move up or down by the action of the hydraulic cylinder 2.

[0040] The initial position of the placement frame 4 is located above the quenching box 1. When the titanium alloy part is quenched, the titanium alloy part is placed in the placement frame 4, and then the placement frame 4 is moved downward by the driving of the hydraulic cylinder 2 and moved below the liquid level of the quenching liquid.

[0041] Example 2

[0042] In this embodiment, when the placement frame 4 enters into the quenching liquid, the splash-proof cover plate 5 will seal the top of the placement frame 4, thereby reducing the splashing of the quenching liquid during quenching.

[0043] A splash-proof cover 5 is provided above the placement frame 4, and a closing mechanism is provided on the placement frame 4. The closing mechanism is used to control the splash-proof cover 5 to close the top of the placement frame 4 when the placement frame 4 moves downward. A plurality of flow holes for facilitating the circulation of quenching liquid are provided on the placement frame 4 and the splash-proof cover 5; the closing mechanism includes a closing rack 6 fixedly connected to the bottom of the quenching box 1, a closing gear 7 is rotatably connected to the placement frame 4, the splash-proof cover 5 is slidably connected to the top of the placement frame 4, and a driven rack is provided at the bottom of the splash-proof cover 5, and the closing gear 7 is respectively meshed with the closing rack 6 and the driven rack.

[0044] The specific method is as follows: when the hydraulic cylinder 2 drives the placing frame 4 to move downward, Figure 2 When the placement frame 4 moves downward, the closed gear 7 will rotate under the action of the closed rack 6, and the closed gear 7 will drive the driven rack to move when it rotates. Because the driven rack and the splash-proof cover 5 are fixedly connected, the closed gear 7 will drive the splash-proof cover 5 to move above the placement frame 4 during the downward driving process to close the top of the placement frame 4. It should be noted that when the titanium alloy part contacts the quenching liquid, the splash-proof cover 5 has already closed the placement frame 4. In this way, the quenching liquid splashing outside the quenching box 1 during quenching can be reduced, and the operating personnel can be protected.

[0045] Example 3

[0046] In this embodiment, the titanium alloy part is turned over during the quenching process of the titanium alloy part, and the contact surface supporting the titanium alloy part is repeatedly changed, so that the quenching liquid can fully contact the surface of the titanium alloy part, thereby improving the quenching efficiency.

[0047] Two rolling mechanisms are arranged in the placement frame 4, and the two rolling mechanisms are arranged in a symmetrical manner. The rolling mechanisms include a placement plate 10 and a rotating plate 11. The titanium alloy parts that need to be quenched are placed on the placement plate 10. A lifting screw 8 is arranged on one side of the placement plate 10 and the rotating plate 11. A rotating fan blade 9 is arranged at the bottom of the lifting screw 8. The flow pump body 3 can drive the rotating fan blade 9 to rotate by using the quenching liquid as the medium.

[0048] The flow pump body 3 can accelerate the flow of quenching liquid in the quenching box 1. The flow direction of the quenching liquid located below the placement frame 4 is opposite to the downward movement direction of the placement frame 4. When the placement frame 4 moves downward, the flow of the quenching liquid will drive the rotating blades 9 to rotate, and the rotating blades 9 are used to drive the lifting screw 8 to rotate.

[0049] A plurality of flow openings for quenching liquid to flow are provided on the placement plate 10 and the rotating plate 11. The function of providing the flow openings is to reduce the impact force of the quenching liquid on the placement plate 10 and the rotating plate 11 when the quenching liquid flows.

[0050] The inner wall of the placement frame 4 is slidably connected with a lifting member 14, and the lifting member 14 is slidably connected with a contact member 15, and the lifting member 14 and the contact member 15 are located on the outside of the lifting screw rod 8; when the titanium alloy part is not placed on the top of the placement plate 10, the contact member 15 and the lifting member 14 are not in contact with the lifting screw rod 8, so the rolling mechanism is at the bottom of the placement frame 4 at this time.

[0051] The outer wall of the lifting screw rod 8 is provided with an external thread, and the side of the contact piece 15 opposite to the lifting screw rod 8 is provided with an internal thread, wherein the internal thread and the external thread are adapted to each other.

[0052] The placement plate 10 is located above the rotating plate 11, and a plurality of telescopic rods for limiting the sliding direction are arranged between the two. The outer wall of the telescopic rod is provided with a trigger spring 12. A connecting rod is provided on the placement plate 10, and the connecting rod and the contact piece 15 are connected by a pushing rod 16. The two ends of the pushing rod 16 are respectively rotatably connected with the connecting rod and the contact piece 15.

[0053] When the titanium alloy part is placed on a placement plate 10 in any tumbling mechanism, the corresponding placement plate 10 will be pressed down by the gravity of the titanium alloy part itself, and the trigger spring 12 will be compressed at this time. The push rod 16 will make the contact piece 15 contact the outer surface of the lifting screw 8, so that the internal thread and the external thread are meshed with each other. At this time, the lifting screw 8 is in a rotating state, and the contact piece 15 and the lifting piece 14 will be driven to move upward as a whole under the action of the thread.

[0054] Refer to the attached Figure 8 The lifting member 14 is connected to a flip block 18, and a rotating shaft 21 is fixedly connected to the flip block 18. The rotating shaft 21 is rotatably connected to the rotating plate 11. There are four flip blocks 18, which are arranged in a rectangular manner on the lifting member 14;

[0055] A flip groove 17 is provided on the lifting member 14, and a flip block 18 is slidably connected in the flip groove 17. A limit spring 22 is provided between the flip block 18 and the inner bottom of the flip groove 17, wherein the limit spring 22 will not be completely compressed under the gravity of the titanium alloy part; when the above-mentioned titanium alloy part is placed on the rotating plate 11, the trigger spring 12 will be compressed, and the elastic coefficient of the limit spring 22 should be greater than the elastic coefficient of the trigger spring 12, and the limit spring 22 will not be compressed at this time.

[0056] The two flip blocks 18 near the center of the quenching box 1 are fixedly connected to the same rotating rod 20, wherein the inner wall of the quenching box 1 is provided with a sliding groove 19, and the rotating rod 20 is slidingly connected to the inner wall of the sliding groove 19, and the top of the sliding groove 19 is lower than the height at which the rotating plate 11 can rise.

[0057] The rotating plate 11 on the rolling mechanism on which the titanium alloy piece is placed will move upward under the action of the thread. When the rotating plate 11 moves upward under the action of the lifting member 14, the rotating rod 20 will slide in the sliding groove 19. When the rotating rod 20 moves to the top position of the sliding groove 19, the rotating rod 20 will not continue to move upward. At this time, the limit spring 22 will be compressed, and the other two flip blocks 18 will continue to move upward a short distance, so that the rotating plate 11 will flip at an angle. The titanium alloy piece on the rotating plate 11 will roll under the component force of gravity and flip to another rolling mechanism at the bottom of the placement frame 4.

[0058] When the titanium alloy part is out of the original tumbling mechanism, the pressure on the rotating plate 11 in the tumbling mechanism will be released, and the tumbling mechanism will be released from contact with the lifting screw 8. Under the action of gravity, the tumbling mechanism will move to the inner bottom of the placement frame 4. In this way, the tumbling mechanism is repeatedly moved up and flipped to change the surface in contact with the titanium alloy part, so that the surface of the titanium alloy part can fully contact the quenching liquid. Improve the quenching efficiency of the titanium alloy part

[0059] The two placement plates 10 are both provided with friction lines 26 at positions close to one end of each other.

[0060] By setting the friction lines 26, the friction force near the bottom of the titanium alloy part can be increased during the downward sliding of the titanium alloy part, thereby achieving a better rolling effect of the titanium alloy part.

[0061] The lower end surface of the placement plate 10 is rotatably connected with a plurality of telescopic members 13, and one end of the telescopic member 13 away from the placement plate 10 is fixedly connected to the inner bottom of the placement frame 4, and the spacing between the plurality of telescopic members 13 is smaller than the width of the quenched titanium alloy part.

[0062] The multiple telescopic members 13 can prevent the titanium alloy part from falling below the high rolling mechanism during the rolling downward movement, thereby ensuring the normal progress of the quenching process.

[0063] The inner wall of the placement frame 4 is slidably connected with a reserved frame 23, the inner wall of the reserved frame 23 is slidably connected with a sliding block 24, the placement plate 10 is rotatably connected with the sliding block 24, and a return spring 25 is provided between the sliding block 24 and the inner wall of the reserved frame 23. By setting the placement frame 4, the sliding direction of the placement plate 10 can be limited, which can increase the stability of the entire device.
