Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a lathe for manufacturing the vacuum roll drum of a paper machine. Background Art

[0002] The paper industry is an industry closely related to the development of the national economy and has a complete and vibrant ecological chain. With the increasing demand for paper products in the market, paper manufacturers' requirements for papermaking efficiency are also increasing. To improve papermaking efficiency, paper mills generally adopt a wider paper-making width and a faster lathe speed. Increasing the paper-making width means increasing the length of the vacuum roll drum of the paper-making lathe. When manufacturing the vacuum roll drum, it needs to go through multiple steps such as blanking, rough turning, finish turning, and surface treatment.

[0003] During blanking, the roll body blank is cut according to size requirements. In the existing cutting technology, the roll body blank is kept stationary during cutting, and then a circular cutting blade is used to separate and cut the roll body. However, due to the hollow inside the cylinder, when the cutting edge of the cutting blade reaches the inside of the cylinder, there is always a part of the blade that does no work actually and does not cut the pipe. And the part of the actual cutting has a smaller contact area with the cylinder thickness part, resulting in a decrease in the overall cutting efficiency. Therefore, a cutting lathe for the roll body blank is needed to improve the blanking efficiency of the roll. Summary of the Invention

[0027] Next, the present invention will be described in detail with reference to the schematic diagrams.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included. Embodiment 1

[0028] Referring to Figures 1 - 2 , for the first embodiment of the present invention, a lathe for manufacturing the drum of a vacuum roll of a paper machine is provided, including a bed body 1. A tool rest 2 is fixedly arranged in the middle part of the top of the bed body 1. An annular cutting tool 3 is rotatably arranged inside the tool rest 2, and the cutting edge of the annular cutting tool 3 faces the center. A cutting mechanism 4 for controlling the annular cutting tool 3 to cut the roller blank, which includes a driving member 41 arranged on the side of the annular cutting tool 3, heat dissipation members 42 arranged on both sides of the tool rest 2, and a cleaning member 43 arranged on one side of the heat dissipation member 42. A rotating mechanism 5 for rotating the workpiece to improve the cutting efficiency, which includes clamping members 51 arranged on both sides of the tool rest 2, a rotating member 52 arranged above the clamping members 51, and an adjusting member 53 arranged at the bottom of the bed body 1.

[0029] Among them, the annular cutting tool 3 is a non-standard part. To meet the requirements of cutting strength, its material should be made of cemented carbide. Embodiment 2

[0030] Referring to Figure 3 , for the second embodiment of the present invention, the difference from the first embodiment is that the driving member 41 includes a first gear ring 411, a first gear 412, and a first motor 413. The first gear ring 411 is sleeved and fixedly arranged on the side of the annular cutting tool 3. The first gear 412 meshes with the first gear ring 411. The first motor 413 is located on the side of the tool rest 2 and fixedly arranged on the top of the bed body 1. The center of the first gear 412 is sleeved on the movable end of the first motor 413.

[0031] Among them, the size and position relationship between the first gear 412 and the first gear ring 411 shown in the figure are only for illustration. In the actual selection of the first gear 412, the transmission ratio between the first gear ring 411 and the first gear 412 meets the high-speed rotation requirements of the annular cutting tool 3.

[0032] The heat dissipation member 42 includes a water storage ring 421, a water distribution grid 422, a second gear ring 423, a second gear 424, a third gear 425, and a water baffle 426. A pair of water storage rings 421 are provided and symmetrically arranged on both sides of the tool holder 2. The water storage ring 421 is rotatably arranged on the side surface of the tool holder 2. The water distribution grid 422 is arranged inside the water storage ring 421 and is separated by a plurality of narrow plate members. One side of the water distribution grid 422 close to the annular cutting tool 3 is not sealed, and its side far from the annular cutting tool 3 is sealed by the side surface of the water storage ring 421.

[0033] The second gear ring 423 is sleeved and fixedly arranged on the side surface of each water storage ring 421. A rotating shaft is arranged at the center of the second gear 424. The second gear 424 meshes with the first gear ring 411. The rotating shaft of the second gear 424 is rotatably arranged on the side surface of the tool holder 2 through a bracket. A pair of third gears 425 are arranged and are respectively coaxially and fixedly arranged at both ends of the rotating shaft of the second gear 424. The third gear 425 meshes with the second gear ring 423. The water baffle 426 is fixedly arranged on the top of the bed body 1. The water baffle 426 is located outside the tool holder 2.

[0034] Among them, the water baffle 426 mainly prevents the cooling water in the water storage ring 421 from being thrown out of the lathe. After being blocked by the water baffle 426, the thrown cooling water can be converged and collected, thereby realizing recycling.

[0035] The cleaning member 43 includes an arc-shaped plate 431, an elastic plate 432, and a water flow hole 433. The arc-shaped plate 431 is fixedly arranged inside the water baffle 426. The arc-shaped plate 431 is located inside the annular cutting tool 3. A baffle is arranged at the edge of the arc-shaped plate 431. A plurality of elastic plates 432 are arranged and fixedly arranged on the surface of the arc-shaped plate 431. One end of the elastic plate 432 far from the arc-shaped plate 431 abuts against the inside of the water distribution grid 422. The water flow hole 433 is opened on the side surface of the elastic plate 432.

[0036] During use: The driving member 41 is used to drive the annular cutting tool 3 to rotate to realize cutting of the workpiece, while the heat dissipation member 42 dissipates heat from the annular cutting tool 3 and the workpiece.

[0037] When cutting the workpiece, the operator turns on the first motor 413. After the first motor 413 starts, it drives the first gear ring 411 to rotate through the first gear 412, and then drives the annular cutting tool 3 to rotate at a high speed. During the cutting operation, the workpiece is arranged tangent to the cutting edge of the annular cutting tool 3. Compared with the traditional circular blade, after the annular cutting tool 3 cuts into the workpiece by a certain thickness, the contact area between it and the inside of the workpiece is larger than that of the circular blade. Therefore, higher cutting efficiency can be obtained during cutting.

[0038] Compared with the traditional circular cutting tool, the annular cutting tool 3 has a small heat dissipation area, so there are certain requirements for heat dissipation. During the cutting operation, cooling water is usually directly sprayed between the blade and the workpiece, while in this equipment, the cooling water will flow into the water storage ring 421. At the same time, the rotation of the annular cutting tool 3 will drive the rotation of the second gear 424, and then drive the rotation of the two third gears 425. The third gear 425 drives the water storage ring 421 to rotate through the second tooth ring 423. Here, the rotation speed of the water storage ring 421 is relatively high. The cooling water in the water storage ring 421 is divided into multiple portions by the water dividing grid 422. The cooling water in each water dividing grid 422 is affected by the centrifugal force when the water storage ring 421 rotates. Therefore, some of the cooling water can follow the rotation of the water storage ring 421, so that the cooling water and the annular cutting tool 3 have a longer contact time, thereby improving the heat dissipation capacity of the heat dissipation part 42 for the annular cutting tool 3.

[0039] Furthermore, when the lathe cuts the workpiece, metal powder will be generated. And since there will be some cooling water remaining in the water storage ring 421, this part of the cooling water will capture some metal powder into the water dividing grid 422 when rotating with the water storage ring 421. This part of the metal powder sinks to the bottom under the action of centrifugal force, thus occupying the capacity in the water dividing grid 422. This will not only cause the cooling water capacity in the water dividing grid 422 to decrease, but also further reduce the heat absorption capacity of the cooling water.

[0040] To ensure the heat dissipation capacity of the cooling water for the blade, when the water storage ring 421 rotates to the upper semi-circle of the tool rest 2, some of the cooling water and metal powder will fall into the arc-shaped plate 431, and then this part of the cooling water will brush out the metal powder from the arc-shaped plate 431. The flowing water holes 433 prevent the powder from accumulating on the side of the elastic plate 432. For the powder that sinks to the bottom in the water dividing grid 422 and cannot fall out of the water storage ring 421 due to the influence of centrifugal force, at this time, the elastic plate 432 can play a role. It can continuously bounce under the resistance of the narrow plate at the edge of the water dividing grid 422. During the bouncing process, it further stirs the powder on the inner wall of the water storage ring 421, so that the powder on the inner wall of the water storage ring 421 becomes loose and falls into the arc-shaped plate 431, and finally is washed out of the arc-shaped plate 431 by the cooling water.

[0041] The remaining structures are the same as those in Embodiment 1. Embodiment 3

[0042] Refer to Figures 4 - 6, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the clamping member 51 includes a rotating frame 511, a rotating cylinder 512, a third gear ring 513, a rotating disc 514, a spiral groove 515, a clamping block 516, a rubber ring 517 and a fixing screw 518. The rotating frame 511 penetrates and is slidably arranged on the top of the rotating frame 511. The rotating cylinder 512 is rotatably arranged inside the rotating frame 511. The third gear ring 513 is sleeved and fixedly arranged at one end of the rotating cylinder 512 close to the tool rest 2.

[0043] The rotating disc 514 is sleeved and fixedly arranged at one end of the rotating cylinder 512 away from the tool rest 2. The spiral groove 515 is opened on the side surface of the rotating disc 514. There are three clamping blocks 516 which are evenly surrounded on the side surface of the rotating disc 514 along the rotating cylinder 512. The side surface of the clamping block 516 is engaged with the spiral groove 515. The rubber ring 517 is sleeved on the side surface of the rotating cylinder 512. One end of the fixing screw 518 penetrates the side surface of the rotating disc 514 and is threadedly connected with the rotating disc 514, and the other end abuts against the side surface of the rubber ring 517.

[0044] Among them, two groups of clamping members 51 are provided and symmetrically arranged on both sides of the tool rest 2. The rotating cylinders 512 of the two groups of clamping members 51 are coaxially arranged; after the fixing screw 518 abuts against the rubber ring 517, it plays a reinforcing role. The rubber ring 517 prevents the fixing screw 518 from rotating relative to the rotating cylinder 512 by means of friction, and after the rubber ring 517 is squeezed, it can generate a rebounding force on the fixing screw 518, thereby increasing the friction force between the fixing screw 518 and the rotating disc 514, and thus avoiding loosening of the fixing screw 518 during processing.

[0045] The rotating member 52 includes a first fixing frame 521, a second fixing frame 522, a second motor 523, a fourth gear 524 and a toothed belt 525. The first fixing frame 521 and the second fixing frame 522 are respectively arranged on both sides of the tool rest 2. The second motor 523 is fixedly arranged inside the first fixing frame 521. The moving end of the second motor 523 is rotatably arranged on the side surface of the second fixing frame 522. There are two fourth gears 524 which are both sleeved on the side surface of the moving end of the second motor 523. Each fourth gear 524 is in transmission connection with the third gear ring 513 through the toothed belt 525.

[0046] Among them, the second motor 523 is provided with a brake, and its function is to prevent the second motor 523 from rotating when powered off.

[0047] The adjusting member 53 includes a connecting plate 531, a third motor 532, and an adjusting screw 533. The bottoms of the rotating frame 511, the first fixing frame 521, and the second fixing frame 522 all penetrate through the top of the bed body 1 and extend to the other side. The connecting plate 531 is fixedly connected to the ends of the rotating frame 511, the first fixing frame 521, and the second fixing frame 522 that extend out of the bed body 1. The third motor 532 is fixedly arranged at the bottom of the bed body 1 through a bracket. The adjusting screw 533 is fixedly arranged at the movable end of the third motor 532 through a coupling. The adjusting screw 533 penetrates through the connecting plate 531 and is in threaded connection with the connecting plate 531. The end of the adjusting screw 533 away from the third motor 532 is rotatably arranged at the bottom of the bed body 1.

[0048] During use: The main function of the rotating mechanism 5 is to help the workpiece rotate. Among them, the clamping member 51 is used to clamp the workpiece, the rotating member 52 is used to provide power for the rotation of the workpiece, and the adjusting member 53 is used to drive the workpiece to move to facilitate cutting.

[0049] First, place the cylindrical workpiece inside the two rotating cylinders 512, then place the part to be cut on the cutting edge. Then, the operator rotates the rotating disk 514 through the fixing screw 518. Driven by the spiral groove 515, the three clamping blocks approach the workpiece, and finally the workpiece is clamped at the center of the rotating cylinder 512, thus achieving the purpose of fixing the workpiece.

[0050] Then the operator can turn on the second motor 523. The motor drives the two fourth gears 524 to rotate. The fourth gears 524 drive the rotating cylinder 512 to rotate through the toothed belt 525, thereby realizing the rotation of the workpiece. At the same time, the third motor 532 drives the whole workpiece to slowly move downward by using the adjusting screw 533 to achieve complete cutting of the workpiece. It should be noted that the rotation speed of the second motor 523 should be set to slow rotation to avoid excessive vibration of the workpiece and damage to the cutting edge.

[0051] In the above process, the rotation of the workpiece enables the cutting edge of the annular cutting tool 3 to always contact all surfaces of the workpiece, which can not only avoid the cutting edge doing empty work, but also accelerate the cutting of the workpiece by the cutting edge. And driven by the adjusting screw 533, the workpiece slowly moves downward, enabling the workpiece to be completely cut. The rotation of the tool and the rotation of the workpiece make the overall cutting process faster, thus increasing the production efficiency of the vacuum roller.

[0052] The remaining structure is the same as that of Embodiment 2.
