Description

Technical Field

[0001] The present invention belongs to the technical field of metal turning, and specifically relates to a turning device for ring-shaped metal forgings. Background Art

[0002] Turning, i.e., lathe machining, is a part of machining. Lathe machining mainly uses a turning tool to machine a rotating workpiece. For ring-shaped metals such as titanium alloy rings, in order to obtain the required shape and size, turning work is also carried out on the titanium alloy rings during production.

[0003] A patent application with the publication number CN115971517B discloses a turning device for automotive metal plates, including a bottom plate, and also including support legs on the lower surface of the bottom plate. A large circular hole is opened at the center of the upper surface of the bottom plate, and a collecting pipe is fixedly connected at the large circular hole. By providing the collecting pipe and the discharge pipe, metal chips generated by cutting can be collected. By providing a lifting motor, a lifting column, and a lifting plate, the rotating cutting device can be moved up and down, so that the metal plate can be cut up and down.

[0004] The above solution still has some problems in actual application. The above device fixes the turning workpiece by clamping the end of the turning workpiece. This method will prevent the external turning work and the internal turning work from being carried out simultaneously. This operation will not only reduce the turning efficiency, but also when turning the other side after one side of the turning workpiece is completed, the turning tool needs to be replaced and repositioned. If the positioning is inaccurate, the machining accuracy will be reduced, affecting the turning quality.

When turning, the inner hole tools and the external turning tools will move together towards the titanium alloy ring through the screw. Eventually, the external turning work and the internal turning work of the titanium alloy ring are carried out simultaneously.

[0018] 2. For a turning equipment for ring-shaped metal forgings of the present invention, by setting the base fixture and the side fixture, when turning the titanium alloy ring, the two side fixtures located above the base fixture can be opened, and then the titanium alloy ring is placed on the surface of the base fixture. This fixture design can facilitate the placement of the titanium alloy ring. And when it is necessary to take away the turned titanium alloy ring, the side fixtures are opened, and the side clamping plates inside the side fixtures will also move away from the titanium alloy ring, thereby releasing the fixation of the titanium alloy ring and facilitating the taking of the titanium alloy ring.

[0019] 3. The turning equipment for ring-shaped metal forgings according to the present invention can automatically feed titanium alloy rings towards the base fixture through the setting of a blanking frame, and the arc-shaped abutting pieces inside the blanking frame can also make the titanium alloy rings drop individually, thus avoiding the phenomenon that multiple titanium alloy rings drop at one time during the blanking process and ultimately affecting the turning work.

DETAILED DESCRIPTION OF THE INVENTION

[0022] In order to make the technical means, creative features, achieved objectives and functions realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Embodiment 1: As Figures 1 to 10 shown, a turning device for ring-shaped metal forgings according to an embodiment of the present invention includes a base frame 1. An operation platform 2 is provided at the upper end of the base frame 1. A turning structure 3 and an adjustment structure 4 are provided on the surface of the operation platform 2, and a titanium alloy ring 5 is placed inside the adjustment structure 4; the turning structure 3 includes: a turning frame 31, the turning frame 31 is slidably connected to the top surface of the operation platform 2; an external turning tool 33, the external turning tool 33 is provided inside the turning frame 31, and the external turning tool 33 is in contact with the outside of the titanium alloy ring 5; an internal hole tool 32, the internal hole tool 32 is provided on one side of the base frame 1, and the internal hole tool 32 is in contact with the inner wall of the titanium alloy ring 5; the adjustment structure 4 includes: a screw rod 405, the screw rod 405 is provided inside the operation platform 2, and the screw rod 405 is threadedly connected to both the turning frame 31 and the internal hole tool 32, and the thread directions at both ends of the screw rod 405 are opposite; a base fixture 407, the base fixture 407 is provided on the surface of the operation platform 2; side fixtures 402, two side fixtures 402 are provided above the base fixture 407, and the two side fixtures 402 and the base fixture 407 form a ring, and the inside of the ring is used to place the titanium alloy ring 5.

[0024] Specifically, when turning a ring-shaped metal such as the titanium alloy ring 5 in the prior art, the titanium alloy ring 5 needs to be placed inside a fixture. The fixture fixes the titanium alloy ring 5 by clamping the end of the titanium alloy ring 5. After the fixing is completed, the fixture is started, and the fixture will drive the titanium alloy ring 5 to rotate together. During the rotation, the turning frame 31 is started, and the turning frame 31 will move towards the titanium alloy ring 5. Eventually, the external turning tool 33 will come into contact with the outside of the titanium alloy ring 5. While the titanium alloy ring 5 is rotating, the external turning tool 33 will perform linear cutting on the surface of the titanium alloy ring 5 and remove the excess material on the surface of the titanium alloy ring 5 according to a predetermined trajectory to obtain the required shape. However, since there are accuracy and dimension requirements for both the inside and outside of the titanium alloy ring 5, internal and external turning needs to be carried out simultaneously during turning. If the above device is used for turning, since the fixing method of the titanium alloy ring 5 during turning is to clamp and fix the end, only one end can be turned during turning. Therefore, the internal turning work and the external turning work of the titanium alloy ring 5 can only be carried out separately. This method will greatly affect the turning efficiency. For this reason, a turning device for ring-shaped metal forgings is designed. When turning the titanium alloy ring 5, only need to place the titanium alloy ring 5 inside the ring formed by the two side fixtures 402 and the base fixture 407 for clamping and fixing. At this time, the fixing method of the titanium alloy ring 5 is to clamp and fix the outer surface. And there is an internal hole tool 32 at one end of the titanium alloy ring 5 and an external turning tool 33 at the other end. The distances between the titanium alloy ring 5, the internal hole tool 32, and the external turning tool 33 are also the same. At this time, the turning frame 31 is started. Since the lower end of the turning frame 31 is threadedly connected to the screw 405, the screw 405 will rotate at this time. The other end of the screw 405 is also threadedly connected to the internal hole tool 32, and the thread directions at both ends of the screw 405 are opposite. So at this time, the turning frame 31 and the internal hole tool 32 will move towards the titanium alloy ring 5 together. Eventually, when the internal hole tool 32 comes into contact with the inner wall of the titanium alloy ring 5, the external turning tool 33 also just comes into contact with the outside of the titanium alloy ring 5, finally realizing the simultaneous turning of the inside and outside of the titanium alloy ring 5, and it is applicable to any titanium alloy ring 5 with different lengths.

[0025] Such as Figures 1 to 7As shown, the turning structure 3 further includes: a first connecting arm 34, the first connecting arm 34 is provided at the lower end of the turning frame 31, and the first connecting arm 34 is threadedly connected to the screw 405; a limiting strip 36, the limiting strip 36 is provided at one end of the inner hole cutter 32, and the limiting strip 36 slides inside the base frame 1; a second connecting arm 35, the second connecting arm 35 is provided at one end of the limiting strip 36, and the second connecting arm 35 is threadedly connected to the screw 405; the adjusting structure 4 further includes: a limiting groove 406, the limiting groove 406 is opened at one end of the inner part of the base frame 1 close to the limiting strip 36, and the limiting strip 36 slides inside the limiting groove 406; an annular track 403, the annular track 403 is provided on one side of the base frame 1; a fixed connecting arm 404, one end of the fixed connecting arm 404 rotates on the inner wall of the annular track 403, and the other end of the fixed connecting arm 404 is fixedly connected to one side of the side clamp 402 and the base clamp 407.

[0026] Specifically, when the side clamp 402 and the base clamp 407 drive the titanium alloy ring 5 to rotate at a high speed, the fixed connecting arm 404 at one end of the side clamp 402 and the base clamp 407 also rotates on the inner wall of the annular track 403, and when the turning frame 31 moves towards the titanium alloy ring 5, the first connecting arm 34 at the lower end of the turning frame 31 will drive the screw 405 to rotate, and since the thread directions at both ends of the screw 405 are opposite, the second connecting arm 35 at the other end of the screw 405 will also drive the inner hole cutter 32 to move towards the titanium alloy ring 5, and the limiting strip 36 will also limit the movement of the inner hole cutter 32, so as to ensure the movement direction of the inner hole cutter 32.

[0027] As Figures 3 to 7 shown, a side clamping plate 410 is slidably connected to the surface of the side clamp 402, and the side clamping plate 410 abuts against the surface of the titanium alloy ring 5. A base clamping plate 409 is slidably connected to the surface of the base clamp 407, and the base clamping plate 409 abuts against the surface of the titanium alloy ring 5. The side clamping plate 410 is rotatably connected to the surface of the base clamp 407.

[0028] Specifically, by setting the side clamp 402 to rotate on the surface of the base clamp 407, the side clamp 402 can be opened before turning, then the titanium alloy ring 5 is placed on the surface of the base clamp 407, and then the side clamp 402 is closed, so that the titanium alloy ring 5 can be clamped and fixed by the ring formed by the two side clamps 402 and the base clamp 407. Then, by pushing the side clamping plate 410 and the base clamping plate 409 towards the titanium alloy ring 5, the titanium alloy ring 5 can be completely fixed.

[0029] As Figures 3 to 7As shown, a rotating shaft 414 is provided on the surface of the base fixture 407, and the side fixture 402 rotates on the arc surface of the rotating shaft 414. A fixed rack 416 is provided at one end of the side clamping plate 410 close to the side fixture 402. A second gear 415 is rotatably connected to the outer wall of the side clamping plate 410, and the second gear 415 meshes with the fixed rack 416. A first gear 411 is provided at one end of the second gear 415. A clamping frame 420 is provided on the surface of the operation platform 2. An arc rack 412 is provided on one side of the clamping frame 420, and the arc rack 412 meshes with the first gear 411. Meshing teeth 413 are provided on the surfaces of the base fixture 407 and the side clamping plate 410. A driving gear 408 is provided at one end of the clamping frame 420, and the driving gear 408 meshes with the meshing teeth 413.

[0030] Specifically, when the titanium alloy ring 5 is clamped and fixed by the ring formed by the two side fixtures 402 and the base fixture 407, the driving gear 408 is started. The driving gear 408 will mesh with the meshing teeth 413 and drive the two side fixtures 402 and the base fixture 407 to rotate at a high speed, so as to perform turning work. After the turning is completed, due to the function of numerical control, the two side fixtures 402 and the base fixture 407 will both rotate to the original position and stop. At this time, the side fixture 402 is opened, and the side fixture 402 will rotate around the rotating shaft 414 as the axis. During the rotation process, the first gear 411 will mesh with the arc rack 412. Finally, the first gear 411 drives the second gear 415 to rotate, and the second gear 415 will drive the side clamping plate 410 to move away from the titanium alloy ring 5 through the fixed rack 416, so that the turned titanium alloy ring 5 can automatically break free from the restraint. Then, the titanium alloy ring 5 can be taken out.

[0031] As Figure 8 shown, auxiliary tracks 426 are provided on both sides of the annular track 403, and the fixed arms 404 slide on the inner walls of the auxiliary tracks 426.

[0032] Specifically, by providing the auxiliary tracks 426 on both sides of the annular track 403, when it is necessary to take out the turned titanium alloy ring 5, the side fixture 402 will rotate around the rotating shaft 414 as the axis. At this time, the fixed arm 404 located behind the side fixture 402 will slide along the inner wall of the auxiliary track 426, so that the fixed arm 404 will not be separated from the annular track 403 when the side fixture 402 is opened.

[0033] As Figure 8 shown, a limit buckle 422 is provided at one end of the inner wall of the auxiliary track 426 close to the annular track 403, and the limit buckle 422 abuts against the fixed arm 404.

[0034] Specifically, since auxiliary tracks 426 are provided on both sides of the annular track 403, during the turning process, the fixed arm 404 can easily enter the interior of the auxiliary track 426, ultimately affecting the turning operation. By setting the limit buckle 422, it can effectively prevent the fixed arm 404 from mistakenly entering the interior of the auxiliary track 426. And when the side fixture 402 is opened, the limit buckle 422 will abut against the fixed arm 404, and at any time press the fixed arm 404 into the interior of the auxiliary track 426, ultimately ensuring that the opening of the side fixture 402 will not be affected.

[0035] As Figures 5 to 7 shown, a contact semi-ring 421 is slidably connected inside the clamping frame 420, and the contact semi-ring 421 is in contact with the titanium alloy ring 5.

[0036] Specifically, during the turning process, due to the friction and cutting force between the external turning tool 33 and the titanium alloy ring 5, a large amount of heat will be generated. These heats are easily transferred to the surfaces of the base fixture 407 and the side fixture 402. At this time, when the titanium alloy ring 5 is taken away from the surface of the base fixture 407, it is very easy to be scalded. Therefore, the contact semi-ring 421 is provided. After the turning is completed, the contact semi-ring 421 is started, and the contact semi-ring 421 will move upward, ultimately contacting the titanium alloy ring 5 and pushing the titanium alloy ring 5 to be separated from the base fixture 407. At this time, when taking the titanium alloy ring 5 again, it will not be scalded by the base fixture 407.

[0037] As Figures 5 to 7 shown, a fixed toothed plate 417 is provided at the lower end of the base clamping plate 409. One end of the interior of the clamping frame 420 close to the fixed toothed plate 417 is rotatably connected with an auxiliary gear 418, and the auxiliary gear 418 meshes with the fixed toothed plate 417. A lifting toothed plate 419 is provided at the lower end of the contact semi-ring 421, and the lifting toothed plate 419 meshes with the auxiliary gear 418.

[0038] Specifically, after the turning of the titanium alloy ring 5 is completed, the base clamping plate 409 also needs to move downward to release the fixation of the titanium alloy ring 5. At this time, the fixed toothed plate 417 below the base clamping plate 409 will drive the lifting toothed plate 419 to move upward through the auxiliary gear 418. The contact semi-ring 421 located above the lifting toothed plate 419 will also contact the titanium alloy ring 5 and push the titanium alloy ring 5 to be separated from the base fixture 407.

[0039] Embodiment 2: As Figures 9 to 10 shown, compared with Embodiment 1, another implementation manner of the present invention is: a blanking frame 401 is provided at the upper end of the base frame 1, and a number of titanium alloy rings 5 are placed inside the blanking frame 401. The opening at the lower end of the blanking frame 401 is located directly above the base fixture 407.

[0040] Specifically, by setting a blanking frame 401 above the base clamp 407, after a titanium alloy ring 5 is turned, the partition located at the lower end of the blanking frame 401 can be opened, so that a titanium alloy ring 5 inside the blanking frame 401 automatically falls to the surface of the base clamp 407, thereby making the loading of the titanium alloy ring 5 faster.

[0041] like Figures 9 to 10 As shown, a rotating rod 424 is provided on the side wall of the blanking frame 401 , and a blanking plate 423 is rotatably connected to the arc surface of the rotating rod 424 . An arc-shaped abutment piece 425 is provided at the end of the blanking plate 423 , and the arc-shaped abutment piece 425 is in contact with the titanium alloy ring 5 .

[0042] Specifically, by setting a rotatable arc-shaped abutment piece 425 on the side wall of the blanking frame 401, when blanking is needed, the arc-shaped abutment piece 425 can be rotated, and the arc-shaped abutment piece 425 will drive the titanium alloy ring 5 at the bottom end of the blanking frame 401 to separate from the blanking frame 401, and then a titanium alloy ring 5 above will be clamped by the arc-shaped abutment piece 425 again, so that only one titanium alloy ring 5 can fall each time the material is blanked.

[0043] Working principle: When turning a ring-shaped metal such as the titanium alloy ring 5, first open the side fixture 402, then place the titanium alloy ring 5 on the surface of the base fixture 407, and then close the side fixture 402 so that the titanium alloy ring 5 can be clamped and fixed by the ring formed by the two side fixtures 402 and the base fixture 407. Start the driving gear 408, and the driving gear 408 will mesh with the meshing tooth block 413 and drive the two side fixtures 402 and the base fixture 407 to rotate at high speed. During the rotation, start the turning frame 31, and the turning frame 31 will move towards the titanium alloy ring 5. When the turning frame 31 moves towards the titanium alloy ring 5, the first connecting arm 34 at the lower end of the turning frame 31 will drive the screw rod 405 to rotate. And because the thread directions at both ends of the screw rod 405 are opposite, the second connecting arm 35 at the other end of the screw rod 405 will also drive the inner hole cutter 32 to move towards the titanium alloy ring 5. Finally, the external turning cutter 33 will contact the outside of the titanium alloy ring 5, and the inner hole cutter 32 will contact the inside of the titanium alloy ring 5. While the titanium alloy ring 5 is rotating, the external turning cutter 33 will perform a linear cutting process on the surface of the titanium alloy ring 5 and remove the excess material on the surface of the titanium alloy ring 5 according to a predetermined trajectory to obtain the required shape. After the turning is completed, due to the function of numerical control, the two side fixtures 402 and the base fixture 407 will both rotate to their original positions and stop. At this time, open the side fixture 402, and the side fixture 402 will rotate around the rotating shaft 414. And during the rotation, the first gear 411 will mesh with the arc-shaped rack 412, and finally the first gear 411 will drive the second gear 415 to rotate. The second gear 415 will drive the side clamping plate 410 to move away from the titanium alloy ring 5 through the fixed rack 416, so that the turned titanium alloy ring 5 can automatically break free from the restraint. At this time, the base clamping plate 409 also needs to move downward to release the fixation of the titanium alloy ring 5. At this time, the fixed tooth plate 417 below the base clamping plate 409 will drive the lifting tooth plate 419 to move upward through the auxiliary gear 418. The abutting half-ring 421 above the lifting tooth plate 419 will also contact the titanium alloy ring 5 and push the titanium alloy ring 5 to separate from the base fixture 407. Then just take out the titanium alloy ring 5.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
