Description

Technical Field

[0001] The invention relates to the field of drawing dies, and more particularly to a drawing die for ceramic precision casting alloy. Background Art

[0002] Drawing dies for ceramic precision casting alloys are widely used in aerospace, automobile manufacturing, machinery manufacturing and other fields. Their advantage is that they can produce high-precision, high-quality, and complex-shaped alloy products while reducing production costs and improving production efficiency. In the field of ceramic precision casting alloys, drawing dies are mainly used to process raw materials into products with specific shapes and sizes through plastic deformation. Their key role is to ensure that the alloy material obtains the required shape and dimensional accuracy during the stretching process while ensuring the quality and performance of the product.

[0003] The working principle of the drawing die is based on the punch and die of the die to punch the sheet. Under the action of the press, the punch pushes the sheet to the die, and the blank holder controls the feeding speed of the material to ensure that the material enters the die cavity evenly. By adjusting the shape, size and stamping process parameters of the punch and die, the drawing processing of alloy products of different shapes and sizes can be achieved. In order to ensure the normal use of the drawing die and extend its service life, regular maintenance and care are required, including cleaning the dirt and residue on the die surface, checking the wear of the die and rust prevention treatment, etc.

[0004] In the prior art, when the punch presses the ceramic alloy plate into the die, the pressure ring will press the ceramic alloy plate to control the feeding speed. At this time, the ceramic alloy plate will rub against the entrance of the die cavity, causing the chamfer of the ceramic alloy plate to be easily excessively pulled, thereby causing the ceramic alloy plate to be prone to strain and cracking.

[0019] (1) The present invention provides compensating force to the plate during the drawing process by means of the L-shaped plate, so as to offset the excessive tensile deformation of the plate. Since the plate is pressed by the drawing ribs during the drawing process, the flow resistance of the plate is increased, thereby reducing the wrinkles of the plate.

[0020] (2) The present invention uses a spray head to spray lubricant onto the plate after the L-shaped plate is pushed. Since the lubricant can be sprayed under the plate during the loading process, the plate can be effectively cooled and lubricated during the drawing process, thereby avoiding the influence of heat generated during the drawing process on the drawing quality of the plate. At the same time, it is also convenient for the plate to be withdrawn after the drawing is completed.

[0021] (3) The present invention guides part of the lubricant to the bottom of the pallet through the collection chamber and lubricates the pallet. Since the lubricant accumulated on the top of the pallet can be quickly discharged to the bottom of the pallet when passing through the collection chamber, it can not only avoid the lubricant on the top of the pallet from being used in time, but also can lubricate the pallet, thereby reducing the wear rate of the pallet during the sliding process.

DETAILED DESCRIPTION

[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 10A drawing die for ceramic precision casting alloy, comprising a machine body 1 and a punch 2 arranged at the telescopic end of a hydraulic device inside the vertical part of the machine body 1, a die 3 is arranged on the upper side of the horizontal part of the machine body 1, the die 3 comprises a die body 31 and a top plate 32, a cylinder 4 is arranged inside the die body 31, a support plate 5 is fixedly connected to the telescopic end of the cylinder 4, the support plate 5 is slidably connected inside the die body 31, and a reduction component 6 is arranged inside and outside the die 3;

[0036] The reduction component 6 includes movable grooves 61 arranged in a circular array and opened between the mold body 31 and the top plate 32, and the movable grooves 61 penetrate the top plate 32, the interior of the movable grooves 61 is slidably connected with an L-shaped plate 62, and the lower side of the interior of the movable grooves 61 is provided with slide grooves 621 arranged in a linear array, and the right side of the upper side of the top plate 32 is fixedly connected with draw ribs 63 arranged in a circular array, and the lower side of the interior of the movable grooves 61 near the vertical part of the L-shaped plate 62 is fixedly connected with sliders 64 arranged in a linear array, and the sliders 64 are slidably connected inside the slide grooves 621, and a tension spring 65 is fixedly connected between the interior of the movable groove 61 and the vertical part of the L-shaped plate 62.

[0037] The outer sliding sleeve of the punch 2 is provided with a pressure ring 21, and an air bag 22 is arranged between the punch 2 and the pressure ring 21. The air bag 22 is connected to an external air supply device. The lower end of the pressure ring 21 is provided with a first positioning groove 66 arranged in a circular array, and the lower side of the pressure ring 21 is provided with a second positioning groove 661 arranged in a circular array. After the first positioning groove 66 and the second positioning groove 661 move downward, they both fit with the drawing rib 63, and the support plate 5 moves upward and is flush with the upper side of the top plate 32.

[0038] The inner and outer parts of the top plate 32 are provided with a pusher component 7 .

[0039] By adopting the above technical scheme, first, the air supply device electrically connected to the external power supply delivers gas to the inside of the cylinder 4, so that the telescopic rod inside the cylinder 4 lifts the support plate 5 upward due to the increase in the air pressure inside the cylinder 4, until the upper side of the support plate 5 is flush with the upper side of the top plate 32. When the pushing component 7 pushes the plate to the top of the support plate 5, the machine body 1 pushes the punch 2 downward through the hydraulic cylinder. At this time, the air bag 22 connected to the external air supply device expands and pushes the blank holder 21 after the external air supply device continuously provides gas. When the punch 2 contacts the plate, the blank holder 21 will also contact the plate. As the punch 2 continues to move downward, the cylinder 4 pulls the support plate 5 downward and always supports the plate. At the same time, the drawing rib 63 above the top plate 32 cooperates with the first positioning groove 66 and the second positioning groove 661 below the blank holder 21 to press the plate. At the same time, As the sheet material squeezed by the punch 2 enters the inside of the die 3, the L-shaped plate 62 in contact with the sheet material is pulled by the sheet material and begins to slide inside the movable groove 61. As the L-shaped plate 62 slides in the slide groove 621 inside the movable groove 61 through the slider 64, the L-shaped plate 62 will also pull the tension spring 65 inside the movable groove 61, so that the L-shaped plate 62 is simultaneously subjected to the force applied by the sheet material and the tension spring 65. At this time, the tension generated by the sheet material during the deformation process will be reduced. After the sheet material is drawn, the tension spring 65 contracts to reset the L-shaped plate 62. Since the sheet material will be suppressed by the drawing ribs 63 during the drawing process, the flow resistance of the sheet material is increased, thereby reducing the wrinkles of the sheet material. At the same time, the L-shaped plate 62 can introduce compensation force during the pulling process, which can effectively offset the excessive tensile deformation of the sheet material to ensure the quality of the sheet material after drawing.

[0040] like Figures 4 to 7 and Fig. 9 As shown, the inside and outside of the mold body 31 and the top plate 32 are jointly provided with a lubrication assembly 67, and the lubrication assembly 67 includes a limit block 671 fixedly connected to the left side of the vertical portion of the left L-shaped plate 62 and arranged in a linear array, and the limit block 671 is slidably connected to the inside of the movable groove 61.

[0041] A striker rod 672 is fixedly connected to the left side of the limit block 671 located at the center, a pressure sensor 673 is provided inside the mold body 31 below the left L-shaped plate 62, the left end of the striker rod 672 is in squeeze contact with the right side of the pressure sensor 673, a storage cavity 674 is provided inside the mold body 31 below the pressure sensor 673, a pumping member 675 is inserted inside the mold body 31 below the left L-shaped plate 62, the bottom end of the pumping member 675 extends into the storage cavity 674, a delivery pipe 676 is inserted between the mold body 31 and the top plate 32, and the delivery pipe 676 is arranged in a rectangular shape, the top end of the pumping member 675 extends to the lower side of the top plate 32, the storage cavity 674 is connected to the delivery pipe 676 through the pumping member 675, the outer side of the delivery pipe 676 is fixedly connected with a nozzle 677 arranged in a linear array, and the nozzle 677 is inserted into the left side of the top plate 32.

[0042] By adopting the above technical solution, first, when the plate is pushed by the pushing component 7, the plate pushes the L-shaped plate 62 on the left side. At this time, the limit block 671 fixed to the L-shaped plate 62 on the left side will pull the impact rod 672. When the impact rod 672 is separated from the pressure sensor 673, the pressure sensor 673 will transmit information to the body 1 and start the pumping member 675 to extract the lubricant from the storage chamber 674. The lubricant extracted from the storage chamber 674 will enter the delivery pipe 676 and be sprayed upward through the nozzle 677. As the plate continues to move, the sprayed lubricant adheres to the bottom of the plate, and then the support plate 5 is lifted upward by the cylinder 4, and the nozzle 677 will be blocked by one side of the support plate 5 and accumulate. The lubricant accumulated in the gap between the support plate 5 and the mold body 31 will be evenly spread around the inner wall of the die 3 as the sheet is squeezed and the support plate 5 moves downward. The lubricant can cool the sheet during the drawing process, and after the sheet is withdrawn, the lubricant originally sprayed on the bottom of the sheet through the nozzle 677 will be spread on the inner wall of the mold body 31 after the sheet is drawn, and lubricate the sheet during the withdrawal process. Since the lubricant can be sprayed on the bottom of the sheet during the loading process, the sheet can be effectively cooled and lubricated during the drawing process, which avoids the influence of the heat generated during the drawing process on the drawing quality of the sheet, and also facilitates the withdrawal of the sheet after the drawing is completed.

[0043] like Figure 6 and Figure 7 As shown, a scraping assembly 68 is disposed inside the mold body 31 , and the scraping assembly 68 includes a collecting cavity 681 opened around the inner wall of the mold body 31 .

[0044] The inner wall of the mold body 31 is provided with discharge holes 682 all around. The discharge holes 682 are located below the collecting cavity 681 . The collecting cavity 681 and the discharge holes 682 are communicated with each other.

[0045] By adopting the above technical solution, first, during the drawing process of the plate, if the pallet 5 moves downward to the entrance of the collecting chamber 681, part of the lubricant will flow into the interior of the collecting chamber 681, and the discharge hole 682 connected to the collecting chamber 681 is located below the collecting chamber 681, but the aperture of the discharge hole 682 is much smaller than the collecting chamber 681, so that the lubricant collected by the collecting chamber 681 is slowly discharged to the bottom of the pallet 5 through the drainage hole, and when the pallet 5 passes through the drainage hole, the discharged lubricant lubricates the pallet 5 again. Since the lubricant accumulated above the pallet 5 can be quickly discharged to the bottom of the pallet 5 when passing through the collecting chamber 681, it not only avoids the lubricant above the pallet 5 from being unable to be used in time, but also can lubricate the pallet 5, thereby reducing the wear rate of the pallet 5 during the sliding process.

[0046] like Figure 6 , Figure 7 and Fig. 9 As shown, a filter assembly 69 is provided inside the collecting chamber 681 . The filter assembly 69 includes a filter screen 691 inserted into the collecting chamber 681 . The shape of the filter screen 691 matches the shape of the collecting chamber 681 .

[0047] By adopting the above technical solution, first, after the lubricant enters the collection chamber 681, the lubricant will first be filtered by the filter 691 inside the collection chamber 681. During the process, the impurities adsorbed by the lubricant after being attached to the surface of the plate can be filtered through the filter 691, and the filtered lubricant is discharged through the drain hole. Since the lubricant entering the collection chamber 681 can be filtered through the filter 691, it can effectively prevent the lubricant from adsorbing impurities on the surface of the plate after being attached to the surface of the plate and causing wear on the surface of the support plate 5, thereby ensuring the service life of the support plate 5.

[0048] like Figures 1 to 5 As shown, the top plate 32 is in a “U” shape, and the pusher component 7 includes a first moving groove 71 opened on the front side of the vertical portion of the back of the top plate 32 .

[0049] An electric push rod 72 is provided inside the first movable groove 71, and the electric push rod 72 is electrically connected to an external power supply. The telescopic end of the electric push rod 72 is fixedly connected to a push plate 73, the back of the push plate 73 is slidably connected to the inside of the first movable groove 71, and the right front part of the push plate 73 is fixedly connected to a rubber plate 74.

[0050] By adopting the above technical solution, first start the electric push rod 72 inside the first movable groove 71 to pull the push plate 73. Because the push plate 73 is fixed to the rubber plate 74, after the rubber plate 74 moves, the plate originally on the other side of the rubber plate 74 will also be pushed and gradually move above the designated support plate 5. During the movement of the support plate 5, it will push the L-shaped plate 62 inside the left movable groove 61. At the same time, the nozzle 677 will spray lubricant to the bottom of the plate, and the plate is gradually pushed so that the sprayed lubricant is evenly distributed under the plate. Since the lubricant can be evenly applied to the bottom of the plate during the gradual loading process, the plate can be smooth during the drawing process after being lubricated, avoiding the wear of the plate surface during the drawing process due to the failure to apply lubricant, thereby once again ensuring the drawing quality of the plate.

[0051] like Figure 2 and Figure 3 As shown, the inner and outer parts of the top plate 32 are jointly provided with a clamping assembly 75 , which includes a second movable groove 751 opened on the opposite surfaces of the front and rear vertical parts of the top plate 32 , and the first movable groove 71 is located to the left of the second movable groove 751 .

[0052] A clamping plate 753 is slidably connected inside the second movable groove 751 , and a pressure spring 752 is fixedly connected between the clamping plate 753 and the opposite surface inside the second movable groove 751 .

[0053] By adopting the above technical solution, first, in the process of the plate being pushed by the rubber plate 74, as the plate contacts the clamping plate 753 inside the second movable groove 751, the clamping plate 753 squeezed by the plate will retract into the second movable groove 751. At the same time, the pressure spring 752 inside the second movable groove 751 will push the clamping plate 753, so that the clamping plate 753 is always in contact with the side of the plate. Since the clamping plate 753 pushed by the pressure spring 752 can always be in contact with the side of the plate, the stability of the plate during the movement can be maintained, thereby avoiding the influence of the drawing quality due to misalignment of the plate during the loading process.

[0054] Working principle: First, the cylinder 4 is controlled by the machine body 1 to push the support plate 5 upward until the upper side of the support plate 5 is flush with the upper side of the top plate 32, and then the electric push rod 72 in the first movable groove 71 is started to pull the push plate 73. After the rubber plate 74 is pushed, the plate on the other side of the rubber plate 74 will also be pushed. During the movement of the support plate 5, it will push the L-shaped plate 62 located in the left movable groove 61. At this time, the L-shaped plate 62 on the left side pulls the impact rod 672 through the limit block 671. After the impact rod 672 is separated from the pressure sensor 673, the pressure sensor The device 673 starts the pumping member 675 in the machine body 1 to extract the lubricant in the storage chamber 674, and the lubricant enters the delivery pipe 676 and is sprayed to the bottom of the plate through the nozzle 677. As the plate contacts the clamping plate 753 in the second movable groove 751, the pressure spring 752 in the second movable groove 751 pushes the clamping plate 753 so that the clamping plate 753 is always in contact with the side of the plate. After the support plate 5 is lifted by the cylinder 4, the nozzle 677 is blocked by one side of the support plate 5 and accumulates in the gap between the support plate 5 and the mold body 31. When the material starts to be drawn, the accumulated lubricant will be evenly spread around the inner wall of the die 3, and after the sheet is withdrawn, the lubricant will be spread on the inner wall of the die body 31. When the machine body 1 pushes the punch 2 downward through the hydraulic device, the airbag 22 pushes the blank holder 21 after expansion, and the blank holder 21 will contact the sheet. The upper drawing rib 63 cooperates with the first positioning groove 66 and the second positioning groove 661 below the blank holder 21 to press the sheet. As the sheet squeezed by the punch 2 enters the inside of the die 3, the L-shaped plate 62 in contact with the sheet will be pulled by the sheet. And it starts to slide inside the movable groove 61 again, and the L-shaped plate 62 will also pull the tension spring 65 inside the movable groove 61. After the plate is drawn, the tension spring 65 contracts to reset the L-shaped plate 62. In the process of the plate being drawn, if the support plate 5 moves downward to the entrance of the collecting chamber 681, part of the lubricant will flow into the interior of the collecting chamber 681 at this time, and will be filtered through the filter screen 691, so that the lubricant collected in the collecting chamber 681 will be slowly discharged to the bottom of the support plate 5 through the drainage hole, and the discharged lubricant will lubricate the support plate 5 again.

[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. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
