Description

A titanium alloy barrel precision forging forming device and its manufacturing process Technical Field

[0001] This invention relates to the field of forging equipment technology, specifically to a titanium alloy tube precision forging forming device and its manufacturing process. Background Technology

[0002] Titanium alloys are characterized by high strength, good corrosion resistance, and high heat resistance. In the 1950s and 60s, the main focus was on developing high-temperature titanium alloys for aero engines and structural titanium alloys for airframes. With technological advancements, forging equipment for titanium alloy barrels primarily involves rough forging. Existing equipment stretches and forges the sintered barrel into a tubular shape, using a reciprocating mechanism to continuously compress it during stretching to achieve a certain degree of uniformity. However, the outer wall flatness and diameter of the forged barrel will have some errors. The reasons for these errors are as follows: during the forging process, the softened sintered barrel is compressed, and excess material in the compression area moves to both sides, easily causing errors. Secondly, even with convenient compression, excess material may not move in one direction, requiring many reciprocating forging cycles to achieve uniformity. Therefore, a precision forging device for titanium alloy barrels is designed to forge the diameter and outer wall flatness after rough forging. Summary of the Invention

[0015] The manufacturing process of the titanium alloy tube precision forging forming device includes the following steps:

[0016] Step 1: The heated and rough-forged tube can be placed in the pushing structure for feeding, and the tube can be slowly moved by the movement and clamping of the three-jaw clamping body, and a core column of a specified size is inserted into the middle of the tube.

[0017] Step 2: After moving the body tube a certain length using the three-jaw clamping body, clamp it and move the left end of the body tube into the toothed tube in the forging structure. After clamping and limiting by the first extrusion roller and the second extrusion roller in the first forging unit and the second forging unit, the three-jaw clamping body can move to the other end of the body tube and clamp it.

[0018] Step 3: When the tube is heated, it can deform under force. Therefore, the first and second extrusion rollers are used to extrude the tube from one end in four directions. The first and second extrusion rollers can rotate on the tube, so that the tube is evenly stressed and forms the corresponding diameter.

[0019] Step 4: During the forging process, the shift frame in the second forging unit can be flipped to make the side wall of the ball contact the side wall of the tube and apply force. As the three-jaw clamping body moves, the tube moves through the toothed tube and the toothed tube rotates at the same time. This allows the ball's arc-shaped wall to squeeze and push the side wall of the tube, causing excess material to move slowly to the other end.

[0020] Step 5: Alternatively, during the ball bearing pushing process, the two first extrusion rollers in the first forging unit can be used to reciprocate and extrude the side wall to achieve precise control of the outer wall diameter and smooth shaping.

[0021] The present invention provides a titanium alloy tube precision forging forming device and its manufacturing process, which have the following advantages:

[0022] 1. This invention allows for precise outer wall forging and shaping by setting the stroke of the first and second extrusion rollers according to the forging diameter;

[0024] 3. This invention enables effective and precise forging of the outer wall of the tube through different forging forces. It is also convenient to feed materials, easy to operate and control, and the equipment can be adjusted to a certain extent according to the diameter and length of the tube.

[0053] Example: As shown in Figures 1-10 of the specification, the manufacturing process of the titanium alloy tube precision forging forming device includes the following steps:

[0054] Step 1: Place the heated tube in the pusher frame 22 supported by two pillars 21. After the second hydraulic cylinder 23 in the control pusher structure 2 retracts, the pusher arm 25 is flipped on the flipping seat 24 to correspond with the pusher groove. The tube is then moved by the movement of the pusher arm 25 to feed the material, and the filling core rod is inserted into the middle of the tube.

[0055] Step 2: Extend the first hydraulic cylinder 17 in the drive moving structure 1, so that the slide 13 extends and moves on the moving platform 11 with the help of the guide wheel 12 and the wheel 5 and moves closer to the left end of the push frame 22; at the same time, drive the first motor 15 to drive the screw rod 14 to rotate, so that the moving seat 16 is subjected to force and moves on the slide 13 to drive the three-jaw clamping body 18 closer to the left end of the push frame 22.

[0056] Step 3: As the body tube moves, it will pass through the conveying hole of the three-jaw gripper 18. After the body tube has passed a certain length, the drive to move the push arm 25 will stop and the push arm 25 will be reset. At this time, it is necessary to control the drive of the three-jaw gripper 18 to grip the body tube.

[0057] Step 4: Then, with the help of the movement of the slide 13 and the movement of the moving seat 16, the left end of the body tube can pass through the toothed tube 33; if the body tube is processed from the left end to the right end, it can be driven by the forging structure 3, and forging can be carried out as the body tube moves.

[0058] If the tube is processed from the right end to the left end, after the three-jaw clamping body 18 passes the tube through the toothed tube 33 for a certain length, the third hydraulic cylinder 40 is controlled to retract and drive, which drives the first extrusion roller 382 and the second extrusion roller 394 in the first forging unit 38 and the second forging unit 39 to move relative to each other for fixed clamping. Then, the three-jaw clamping body 18 can be moved to the right end of the tube for clamping, and then the tube can be passed through the toothed tube 33, so that the right end of the tube is located between the first forging unit 38 and the second forging unit 39 for forging.

[0059] Step 5, Forging Processing Method 1

[0060] The third hydraulic cylinder 40 is driven to extend and retract, which causes the first forming frame 381 and the second forming frame 391 on the drive seat 37 to move relative to each other, thereby causing the first extrusion roller 382 to move relative to each other and the second extrusion roller 394 to move relative to each other, so as to reciprocate to extrude the outer side of the tube and achieve forging of the outer wall of the tube.

[0061] It can also drive the second motor 35, which meshes with the toothed tube 33 through the transmission gear 36, so that the toothed tube 33 rotates on the main frame 31 with the help of the first bearing 32, driving the forging frame 34 to rotate around the body tube, and thus forging the outer wall of the heavier body tube in all directions as the body tube moves.

[0062] Step Six, Forging Processing Method Two

[0063] The fourth hydraulic cylinder 393 in the second forging unit 39 is driven to retract, causing the shift frame 392 to flip on the second forming frame 391, moving the second extrusion roller 394 away from the body tube, and causing the ball bearing 396 to adhere to the outer wall of the body tube to apply force.

[0064] The ball bearing 396 exerts force on the side wall of the body tube by means of the arc-shaped wall surface. As the toothed tube 33 rotates and the body tube moves, it squeezes and pushes, causing the excess material to move slowly to the other end. As the body tube moves and the toothed tube 33 rotates, the ball bearing 396 can rotate on one end of the universal joint and the universal joint can rotate within one end of the transposition frame 392.

[0065] Simultaneously, the first forging unit 38 can be driven to perform extrusion forging on the wall surface pushed by the ball 396 with the help of the first extrusion roller 382.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

5. The manufacturing process of a titanium alloy tube precision forging forming device according to claim 4, characterized in that: The process includes the following steps: Step 1: The heated and rough-forged tube is placed in the pushing structure (2) for feeding, and the tube is slowly moved by the movement and clamping of the three-jaw clamping body (18), and a core column of a specified size is inserted into the middle of the tube; Step 2: The tube is moved a certain length by the three-jaw clamping body (18) and clamped, and the left end of the tube is moved and inserted into the toothed tube (33) in the forging structure (3). After being clamped and limited by the first extrusion roller (382) and the second extrusion roller (394) in the first forging unit (38) and the second forging unit (39), the three-jaw clamping body (18) can move to the other end of the tube and clamp it; Step 3: The tube is deformed by force after being heated, so the tube is clamped from one end by the first extrusion roller (382) and the second extrusion roller (394).
