Description

Technical Field

[0001] The invention relates to the field of titanium alloy plate processing, and more specifically to a titanium alloy plate hot pressing device. Background Art

[0002] Titanium alloy sheet is an alloy sheet based on titanium and composed of other elements. Titanium alloy is widely used in aerospace, shipbuilding, chemical industry, medical and other fields due to its high strength, good corrosion resistance and high heat resistance. The production process of titanium alloy sheet includes smelting, casting, rolling, heat treatment and other links. Each link requires strict control of process parameters and operating skills to ensure the overall quality and performance of titanium alloy sheet. For example, the ratio of alloy elements and smelting temperature need to be accurately controlled during smelting; rolling force, rolling speed and temperature need to be controlled during rolling; heat treatment eliminates residual stress of the sheet and improves its performance through annealing, solution treatment and aging treatment.

[0003] Hot pressing of titanium alloy sheets is an important metal processing technology. It uses high temperature and pressure to deform titanium alloy sheets to obtain parts of the desired shape and size. Titanium alloy sheets have high plasticity and low deformation resistance at high temperatures, and can be deformed by applying pressure. During the hot pressing process, the sheet is heated to an appropriate temperature and then placed in a mold. Under the action of pressure, plastic flow occurs, and finally the mold cavity is filled and cooled and solidified to form parts of the desired shape.

[0004] In the prior art, as the male mold presses the titanium alloy plate into the female mold cavity, some parts of the titanium alloy plate will rub against the entrance of the female mold cavity, which affects the flow trend and deformation law of the titanium alloy plate during the hot pressing process, and causes pulling on some parts of the titanium alloy plate, thereby causing stretching of the titanium alloy plate.

[0020] (2) The heat generated by the heating rod can be transferred to the two support plates on both sides by the heat conduction plate provided in the present invention.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 10 A titanium alloy plate hot pressing device comprises an operating table 1 and a female mold 2 fixedly installed on the lower side of the operating table 1, a male mold 3 is fixedly installed on the upper side of the operating table 1, and a profile compensation component 4 is provided inside and on the upper side of the female mold 2. The profile compensation component 4 comprises a movable groove 41 opened on the upper side of the operating table 1, and the number of the movable grooves 41 is four;

[0036] The four movable grooves 41 are all slidably connected with support plates 42 inside, the length of the two front and rear support plates 42 is greater than the length of the left and right support plates 42, and the sides away from the left and right support plates 42 are fixedly connected with a first pressure spring 43, the number of the single-side first pressure springs 43 is multiple, and the other end of the first pressure spring 43 is fixedly connected to the side of the left and right movable grooves 41 away from the first pressure spring 43, and the lower sides of the left and right movable grooves 41 are provided with sliding grooves 44, and the number of sliding grooves 44 is multiple, and the interiors of the multiple sliding grooves 44 are all slidably connected with sliders 45, and the upper sides of the multiple sliders 45 are fixedly connected to the lower side of the same support plate 42, and the lower sides of the front and rear support plates 42 are fixedly connected with return springs 48, and the number of return springs 48 is multiple, and the bottom ends of the multiple return springs 48 are fixedly connected to the lower side of the same movable groove 41.

[0037] By adopting the above technical solution, the heated titanium alloy plate is first placed on the upper side of the female mold 2, and then the male mold 3 is pushed downward by the operating table 1. After being squeezed by the male mold 3, the titanium alloy plate will sink into the female mold 2 and gradually take shape. In the process of the male mold 3 squeezing the titanium alloy plate, the deformed titanium alloy plate will squeeze the four support plates 42 at the same time. The support plates 42 located in the movable grooves 41 on the left and right sides will move in the movable grooves 41 after being squeezed. At this time, the support plates 42 slide in the slide grooves 44 below the movable grooves 41 through the sliders 45 below them, so that the range of the first pressure spring 43 pushing the support plate 42 is limited, and the first pressure spring 43 in the movable groove 41 is squeezed. The elastic force of the first pressure spring 43 itself will also push the support plate 42, so that the support plate 42 always pushes the side of the titanium alloy plate. At this time, the force applied to the titanium alloy plate during deformation will be offset by the force generated when the support plate 42 pushes it. The two support plates 42 located on the front and rear sides will be embedded in the movable grooves 41 at the corresponding positions after being squeezed by the titanium alloy plate. At this time, the reset spring member 48 will push the corresponding support plate 42 upward, and the bending part of the titanium alloy plate will always fit tightly with the arc-shaped surfaces of the four support plates 42. Since the titanium alloy plate always provides a reverse deformation force for the titanium alloy plate through the support plate 42 during deformation, the introduced compensation force can effectively offset the tensile deformation of the plate, thereby ensuring the quality of the titanium alloy plate after processing.

[0038] like Figure 3 and Figure 5 As shown, a temperature compensation component 46 is disposed inside the mother mold 2 , and the temperature compensation component 46 includes two mounting cavities 461 opened at the upper part of the inside of the mother mold 2 .

[0039] A heating rod 462 is fixedly installed inside the two installation cavities 461, and a heat conducting plate 463 is slidably overlapped on the outer side of the two heating rods 462. The upper sides of the two heat conducting plates 463 are fixedly connected to the lower sides of the two support plates 42 located on the left and right sides respectively.

[0040] By adopting the above technical solution, the heating rod 462 inside the installation cavity 461 is first started for preheating. When the heating rod 462 generates heat, the heat conducting plate 463 overlapped on the top of the heating rod 462 is always in contact with the heating rod 462, and the other side of the heat conducting plate 463 is in contact with the two support plates 42 on both sides, so that the heat generated by the heating rod 462 will be conducted to the bending part of the titanium alloy plate, and in the process of the movement of the support plate 42, the heat conducting plate 463 will also move above the heating rod 462 and always conduct heat. Since the cooling efficiency of the titanium alloy plate inside the mother mold 2 is different from that of the titanium alloy plate exposed above the mother mold 2, the support plate 42 will always conduct heat to the bending part of the titanium alloy plate while supporting the bending part of the titanium alloy plate, so as to increase the shaping of this area and reduce the tensile stress.

[0041] like Figures 8 to 10 As shown, a pressure compensation component 47 is provided on the upper side of the female mold 2 and the interior of the male mold 3 . The pressure compensation component 47 includes a pressing ring 471 fixedly connected to the lower side of the interior of the male mold 3 .

[0042] A pressure rod 472 is clamped inside the pressing ring 471, and there are multiple pressure rods 472. A limiting groove 473 is provided on the outer side of the multiple pressure rods 472. A first magnetic block 474 is slidably connected to the inside of the pressing ring 471, and there are four first magnetic blocks 474. The four first magnetic blocks 474 are all slidably connected to the inside of the pressing ring 471. A second pressure spring 477 is fixedly connected to the upper side of the first magnetic block 474, and there are multiple second pressure springs 477. The top end of the second pressure spring 477 is fixedly connected to the upper side of the inside of the pressing ring 471, and a limiting rod 475 is fixedly connected to the lower side of the first magnetic block 474, and there are multiple limiting rods 475.

[0043] A second magnetic block 476 is fixedly installed on the upper side of the mother mold 2, and the number of the second magnetic blocks 476 is multiple. After the pressing ring 471 drives the first magnetic block 474 to move downward, the lower side of the first magnetic block 474 and the upper side of the second magnetic block 476 magnetically repel each other. After the first magnetic block 474 and the second magnetic block 476 repel each other, the limiting rod 475 is pulled out of the limiting groove 473.

[0044] By adopting the above technical solution, first, during the process of the male mold 3 and the female mold 2 approaching each other, the second pressure spring 477 inside the pressing ring 471 will push the first magnetic block 474, so that the limiting rod 475 under the first magnetic block 474 is inserted into the limiting groove 473 outside the pressing rod 472. When the first magnetic block 474 and the second magnetic block 476 begin to repel each other, the first magnetic block 474 will squeeze the second pressure spring 477 and pull the limiting rod 475 out of the limiting groove 473. Then, the pressing ring 471 inside the male mold 3 will contact the titanium alloy plate placed above the female mold 2 while continuously pressing the titanium alloy plate, and the titanium alloy plate After the material is pulled, the freely rotatable pressure rod 472 inside the pressing ring 471 will rotate in the direction of movement of the titanium alloy plate and release part of the force for the titanium alloy plate. After waste chips are stuck to the outside of the pressure rod 472, the pressure rod 472 can be rotated to allow the waste chips stuck to the outside of the pressure rod 472 to be scraped off through the inner wall of the pressing ring 471. While the titanium alloy plate is being shaped, the pressing ring 471 continues to press the part of the titanium alloy plate outside the female mold 2. By adjusting the gap between the female mold 2 and the male mold 3, the flow speed and deformation of the plate in a specific area can be controlled, thereby compensating for the deformation caused by stretching to a certain extent.

[0045] like Figure 4 As shown, the interior and inner surface of the mother mold 2 are jointly provided with a lubricating component 5, and the lubricating component 5 includes two storage chambers 51 opened in the interior of the mother mold 2, and a storage cavity 52 is opened on the inner surface of the mother mold 2. A spraying component 53 is fixedly installed in the storage cavity 52, and the spraying component 53 is composed of a nozzle and a conduit, and the conduit extends to the interior of the storage chamber 51. The lower sides of the two support plates 42 on the front and rear sides are fixedly connected with a striker 54, and two pressure sensors 55 are fixedly installed in the interior of the mother mold 2. The bottom ends of the two strikers 54 are respectively squeezed and contacted with the upper sides of the two pressure sensors 55, and the pressure sensor 55 and the spraying component 53 are electrically connected to the external controller.

[0046] By adopting the above technical solution, first, when the two support plates 42 located at the front and rear sides are squeezed, the impact rod 54 below them will squeeze the pressure sensor 55, so that the pressure sensor 55 activates the spraying part 53 through the external controller to extract the lubricant inside the storage chamber 51, and the lubricant extracted from the conduit is finally sprayed out from the storage cavity 52 through the nozzle. In the process of shaping the titanium alloy plate, the sprayed lubricant will be blocked by the titanium alloy plate and flow back into the storage cavity 52, and finally accumulate in the storage cavity 52. ​​In the process of withdrawing the titanium alloy plate, the titanium alloy plate is pulled upward. The lubricant in the storage cavity 52 will also stick to the outside of the titanium alloy plate. After the titanium alloy plate is completely taken out, the lubricant will flow into the interior of the mother mold 2 due to the loss of the shielding of the titanium alloy plate, and the lubricant sprayed from the nozzle will fly to the inner walls of the mother mold 2 on the opposite side and on both sides. Since the sprayed lubricant sticks to the outside of the titanium alloy plate, the titanium alloy plate can be more conveniently withdrawn. At the same time, because the storage cavity 52 is blocked by the titanium alloy plate, during the upward movement of the titanium alloy plate, the waste chips on the outside of the titanium alloy plate will be absorbed by the lubricant to avoid scratches on the surface of the titanium alloy plate caused by the waste chips during the withdrawal process.

[0047] like Figure 5 As shown, a filter assembly 56 is provided inside the mother mold 2, and the filter assembly 56 includes a filter screen 561 fixedly installed inside the storage cavity 52, and a conduit in the spraying member 53 passes through the filter screen 561. A drainage hole 562 is provided on the inner surface of the mother mold 2, and the number of the drainage holes 562 is multiple, and the multiple drainage holes 562 are connected to the same storage cavity 52.

[0048] By adopting the above technical scheme, the lubricant accumulated in the storage chamber 52 will first be discharged through the multiple drainage holes 562 opened below the storage chamber 52 and connected to each other, and flow to the titanium alloy plate. A filter screen 561 is installed inside the storage chamber 52, so that the lubricant carrying waste chips will be filtered through the filter screen 561 after re-entering the storage chamber 52, and the filtered lubricant can be discharged from the drainage hole 562. After the titanium alloy plate is returned, the lubricant discharged from the drainage hole 562 will flow to the deep inner cavity of the mother mold 2. Since the lubricant re-entered into the storage chamber 52 can be filtered through the filter screen 561, it can avoid the waste chips from clogging the drainage holes 562 with smaller apertures, and at the same time ensure the cleanliness of the lubricant, and prevent the waste chips from causing wear to the titanium alloy plate again.

[0049] like Figures 5 to 7 As shown, a cleaning assembly 57 is provided at the lower inner portion of the mother mold 2 , and the cleaning assembly 57 includes a plurality of drainage grooves 571 opened at the lower inner side of the inner mother mold 2 .

[0050] The interiors of the multiple drainage grooves 571 are all slidably connected with guide grooves 572, and the number of guide grooves 572 in a single drainage groove 571 is two, the interiors of the two guide grooves 572 are all slidably connected with guide blocks 573, the opposite surfaces of the two guide blocks 573 are fixedly connected with the same sealing strip 574, the sealing strip 574 is slidably connected in the drainage groove 571, and the surface of the sealing strip 574 is provided with a through groove 575, and the through groove 575 is in an inverted "L" shape, the lower sides of the two guide blocks 573 are fixedly connected with a third pressure spring 576, and the number of single-sided third pressure springs 576 is multiple, and the other ends of the multiple third pressure springs 576 are fixedly connected to the side of the guide groove 572 away from the third pressure spring 576.

[0051] By adopting the above technical scheme, firstly, the titanium alloy plate will squeeze the multiple sealing strips 574 below it during the shaping process, so that the sealing strips 574 are embedded in the drainage groove 571. When the titanium alloy plate is unloaded, the guide blocks 573 on both sides of the sealing strip 574 will be pushed by the third pressure spring 576 inside the guide groove 572, so that the through groove 575 opened in the sealing strip 574 is exposed to the inner cavity of the mother mold 2, and the lubricant flowing into the inner cavity of the mother mold 2 will carry the waste chips absorbed from the inside of the mother mold 2 and discharge from the through groove 575 into the drainage groove 571, and finally discharged from the mother mold 2. Since the through groove 575 is exposed to the inside of the mother mold 2 after the titanium alloy plate is unloaded, the waste chips generated during the shaping process of the titanium alloy plate are absorbed by the lubricant and discharged from the mother mold 2 together, thereby further avoiding damage to the titanium alloy plate by the waste chips.

[0052] Working principle: First, push the male mold 3 downward through the operating table 1, and shape the titanium alloy plate after pressing it into the female mold 2. The deformed titanium alloy plate will squeeze the four support plates 42 at the same time. The support plates 42 on the left and right sides will squeeze the first pressure spring 43 in the moving groove 41 after being squeezed, and the first pressure spring 43 will also push the side of the titanium alloy plate through the support plates 42. At this time, the support plate 42 slides in the slide groove 44 below the moving groove 41 through the slider 45 below it, so that the range of the first pressure spring 43 pushing the support plate 42 is limited, and the two support plates 42 on the front and rear sides will be embedded in the moving groove 41 at the corresponding position. At this time, the reset spring member 48 will The support plate 42 is pushed upward, and the heat generated by the heating rod 462 inside the installation cavity 461 conducts the heat conducting plate 463 to the two support plates 42 on both sides, so that the heat generated by the heating rod 462 will be conducted to the bending part of the titanium alloy plate. In the process of the male mold 3 and the female mold 2 approaching, the second pressure spring 477 inside the pressing ring 471 will push the first magnetic block 474, so that the limiting rod 475 under the first magnetic block 474 is inserted into the limiting groove 473 on the outside of the pressing rod 472. When the first magnetic block 474 and the second magnetic block 476 begin to repel each other, the first magnetic block 474 pulls the limiting rod 475 out of the limiting groove 473, and then the pressing ring 471 continues to press the titanium alloy plate. After the titanium alloy plate is pulled, the pressing ring 471

[0053] The internal freely rotatable pressure rod 472 will rotate in the direction of movement of the titanium alloy plate and release part of the force for the titanium alloy plate;

[0054] When the support plates 42 on the front and rear sides are squeezed, the impact rod 54 below them will squeeze the pressure sensor 55, so that the pressure sensor 55 activates the spraying part 53 through the external controller to extract the lubricant in the storage chamber 51 and spray it out from the storage cavity 52. ​​During the shaping process of the titanium alloy plate, the sprayed lubricant will be blocked, so that it will flow back into the storage cavity 52 and absorb the waste chips on the outside of the titanium alloy plate, and finally accumulate in the storage cavity 52. ​​When the titanium alloy plate is withdrawn, the lubricant will flow into the interior of the mother mold 2 due to the loss of the shielding of the titanium alloy plate, and the lubricant sprayed by the nozzle will fly to the inner wall of the mother mold 2 on the opposite side and on both sides, and first accumulate in the storage cavity 52. The lubricant inside the storage cavity 52 will be discharged through the drain hole 562 and flow to the titanium alloy plate. A filter 561 is installed inside the storage cavity 52 to filter the lubricant. The filtered lubricant can be discharged from the drain hole 562. The lubricant discharged from the drain hole 562 will flow to the deep inner cavity of the mother mold 2. The guide blocks 573 on both sides of the sealing strip 574 will be pushed by the third pressure spring 576 inside the guide groove 572, so that the through groove 575 opened inside the sealing strip 574 is exposed to the inner cavity of the mother mold 2, and the lubricant flowing to the inner cavity of the mother mold 2 will carry the waste chips adsorbed from the inside of the mother mold 2 and be discharged from the through groove 575 into the drain groove 571, and finally discharged from the mother mold 2.

[0055] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
