Description

Technical Field

[0001] This invention relates to the field of casting processing technology, specifically to a hydraulic device for casting processing. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is processed by subsequent means such as grinding to obtain an object with a certain shape, size and performance. When processing metal, it is often necessary to use hydraulic devices to press and shape the metal parts. Therefore, it is necessary to design a hydraulic device for casting processing.

[0003] The announcement number CN 216324613 U discloses a hydraulic forming device for metal processing. It achieves the effect of extension and retraction by setting a first hydraulic rod and a second hydraulic rod, the effect of sliding by setting a first slide groove and a second slide groove, the effect of hydraulic forming by setting an upper module and a lower module, the effect of guiding by setting a guide rod and a guide cylinder, and the effect of blowing by setting a blower, thus realizing the function of a hydraulic forming device for metal processing.

[0004] This hydraulic forming device for metal processing can move the upper module downwards through the first and second hydraulic rods inside, allowing the upper module to press and form metal parts. However, the device does not have a mechanism to fix the metal parts. When the metal parts are being pressed, if they are hit by an external force, their position under the upper module will change, making it impossible to press the metal parts successfully. This wastes materials and is inconvenient to use, so it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a hydraulic device for casting processing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hydraulic device for casting processing, including a support column, a processing table fixedly connected to the top of the support column, a pressing and moving mechanism fixedly connected to the top of the processing table, an auxiliary mechanism fixedly connected to the middle of the inner side of the pressing and moving mechanism, a forming frame fixedly connected inside the processing table, and a discharge mechanism fixedly connected inside the forming frame.

[0007] The pressing and moving mechanism includes a pressing component and a moving component. The pressing component is disposed on the top of the processing table, and the moving component is disposed on the bottom of the processing table. The moving component is disposed on top of the pressing component.

[0008] According to the above technical solution, the pressing assembly includes a cylinder, a first movable plate is fixedly connected to the bottom of the cylinder, a limit rod is slidably connected to the inner side of the first movable plate, the limit rod is fixedly connected to the inner side of the processing table, a pressing rod is fixedly connected to the middle of the bottom of the first movable plate, a pressing plate is provided at the bottom of the pressing rod, the top of the pressing plate is in contact with the bottom of the pressing rod, a hollow cylinder is slidably connected to the periphery of the pressing plate, the hollow cylinder is fixedly connected to the bottom of the inner side of the processing table, a sliding rod is fixedly connected to the bottom of the pressing plate, a limit ring is slidably connected to the periphery of the sliding rod, the limit ring is fixedly connected to the inner side of the hollow cylinder, a first spring is sleeved around the periphery of the sliding rod, a rack plate is fixedly connected to the bottom of the sliding rod, a gear is meshed on the front of the rack plate, a threaded rod is fixedly connected inside the gear, the threaded rod is rotatably connected to the inner side of the processing table, a threaded plate is threadedly connected to the periphery of the threaded rod, a fixed rod is slidably connected inside the threaded plate, and the fixed rod is fixedly connected to the inner side of the processing table.

[0009] According to the above technical solution, the top of the first spring is fixedly connected to the bottom of the pressing plate, and the bottom of the first spring is fixedly connected to the top of the limiting ring. When the pressing rod does not press the pressing plate, the first spring can drive the pressing plate to move upward, so that the pressing plate can drive the sliding rod to move upward, and the pressing plate can return to its original position.

[0010] According to the above technical solution, the moving component includes a support plate, which is fixedly connected to the top of a threaded plate. A hollow block is fixedly connected to the top of the support plate. A sliding rod is slidably connected to the top of the hollow block. A second spring is sleeved around the sliding rod. A pressing plate is fixedly connected to the top of the sliding rod. A limiting plate is fixedly connected to the bottom of the sliding rod. A locking plate is engaged with the left side of the limiting plate. A second moving plate is fixedly connected to the right side of the locking plate. The second moving plate is slidably connected to the inside of the hollow plate. A connecting rod is slidably connected to the inside of the locking plate. The connecting rod is fixedly connected to the inside of the hollow block. A third spring is sleeved around the connecting rod. The left side of the third spring is fixedly connected to the right side of the locking plate, and the right side of the third spring is fixedly connected to the right side of the inside of the hollow block.

[0011] According to the above technical solution, the top of the second spring is fixedly connected to the top of the hollow block, and the bottom of the second spring is fixedly connected to the top of the limiting plate. When the snap-fit ​​plate does not limit the limiting plate, the second spring can drive the sliding rod to move upward through the limiting plate, so that the sliding rod can drive the pressing plate to move upward, so that the pressing plate cannot press and fix the metal plate.

[0012] According to the above technical solution, the discharge mechanism includes a second arc-shaped plate, which is fixedly connected to the bottom of the threaded plate. A second short rod is fixedly connected to the inner side of the second arc-shaped plate. A rotating plate is rotatably connected to the outer periphery of the second short rod. A first short rod is rotatably connected to the right side inside the rotating plate. A first arc-shaped plate is fixedly connected to the front and rear sides of the first short rod. An extrusion block is fixedly connected to the top of the first arc-shaped plate. A push plate is fixedly connected to the top of the extrusion block.

[0013] According to the above technical solution, the molding frame has a groove inside that corresponds to the size of the push plate, and the push plate and the extrusion block are slidably connected inside the molding frame. When the metal sheet is pressed and formed inside the molding frame, the extrusion block can drive the push plate to move upward, so that the push plate can push the formed metal sheet and the formed metal sheet can be quickly demolded.

[0014] According to the above technical solution, the auxiliary mechanism includes a pressing column, which is fixedly connected to the bottom of the first movable plate. A telescopic rod is fixedly connected to the top of the pressing column, and a fourth spring is sleeved around the telescopic rod. A fixed plate is fixedly connected to the bottom of the telescopic rod, and the fixed plate is slidably connected to the inside of the pressing column. A squeezing cylinder is fixedly connected to the bottom of the fixed plate, and a sliding plate is fixedly connected to the periphery of the fixed plate. A sliding ring is fixedly connected to the periphery of the sliding plate.

[0015] According to the above technical solution, the top of the fourth spring is fixedly connected to the top of the inner part of the pressing column, and the bottom of the fourth spring is fixedly connected to the top of the fixing plate. When the pressing column does not press the metal sheet, the fourth spring can drive the extrusion cylinder to move downward through the fixing plate, and the fixing plate can drive the sliding ring to move downward through the sliding plate, so that the extrusion cylinder and the sliding ring can demold the formed metal sheet and prevent the metal sheet from sticking to the outer periphery of the pressing column.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. The hydraulic device for processing the casting, through a set pressing and moving mechanism, can drive the first moving plate to move downward through a cylinder, so that the first moving plate can press the pressing plate through the pressing rod, so that the pressing plate can drive the sliding rod to move downward, so that the sliding rod can drive the rack plate to move, so that the rack plate can drive the gear to rotate, so that the gear can drive the threaded plate to move through the threaded rod, so that the threaded plate can drive the hollow block to move through the support plate, so that the hollow block can drive the clamped metal plate to move, so that the metal plate can be pressed and formed by the pressing column.

[0018] 2. The hydraulic device for processing the casting, through the set pressing component, can drive the first moving plate to move through the set cylinder. When the first moving plate moves, it can drive the pressing column to move downward, so that the pressing column can press the metal plate. After the pressing plate is completed, the pressing rod moves upward. When the pressing plate is not pressed, the first spring can drive the sliding rod to move upward, so that the rack plate can drive the gear to reverse, so that the gear can drive the threaded rod to reverse, so that the threaded rod can drive the threaded plate to return to its original position, so that the hollow block returns to its original position.

[0019] 3. The hydraulic device for processing this casting, through a set moving component, places the metal sheet to be pressed and formed onto the top of the hollow block, presses down the pressing plate, causing the limiting plate to move downwards, allowing the limiting plate to squeeze the snap-fit ​​plate, allowing the snap-fit ​​plate to limit the limiting plate, and allowing the pressing plate to press the metal sheet.

[0020] 4. In the hydraulic device for processing the casting, when the metal sheet is pressed into shape, the hollow block moves to the right and the second moving plate is squeezed by the forming frame, causing the second moving plate to drive the snap-fit ​​plate away from the limit plate, so that the second spring can drive the pressing plate to move upward, so that the pressing plate cannot press and fix the metal sheet.

[0021] 5. The hydraulic device for processing the casting, through its discharge mechanism, allows the threaded plate to move to the right, via the second arc plate, causing the second short rod to move. This, in turn, causes the rotating plate to rotate downwards, which in turn causes the extrusion block and push plate to move downwards via the first short rod and the first arc plate. After the metal sheet is pressed and formed, when the threaded plate moves to the left, it again causes the second short rod to move via the second arc plate. This, in turn, causes the rotating plate to rotate, which in turn causes the extrusion block and push plate to move via the first short rod and the first arc plate. The push plate then pushes the formed metal sheet away from the forming frame, making it easier for workers to handle.

[0022] 6. The hydraulic device for processing this casting, through the auxiliary mechanism, allows the fourth spring to drive the telescopic rod downward when the pressed metal sheet adheres to the outer surface of the pressing column. This telescopic rod then drives the extrusion cylinder downward through the fixed plate. The telescopic rod, in turn, drives the sliding plate downward through the fixed plate, which in turn drives the sliding ring downward. This allows the extrusion cylinder and the sliding ring to push the formed metal sheet, causing it to slide off the outside of the pressing column for easy collection by workers.

[0039] Example 2

[0040] See Figure 1-7Furthermore, based on Embodiment 1, the movable component 62 further includes a support plate 621, which is fixedly connected to the top of the threaded plate 612. A hollow block 627 is fixedly connected to the top of the support plate 621. A sliding rod 625 is slidably connected to the top of the hollow block 627.

When the snap-fit ​​plate 628 does not limit the limiting plate 623, the second spring 624 can drive the sliding rod 625 to move upward through the limiting plate 623, so that the sliding rod 625 can drive the pressing plate 626 to move upward, so that the pressing plate 626 cannot press and fix the metal plate.

[0042] Example 3

[0043] See Figure 1-7 Furthermore, based on Embodiment 1, the discharge mechanism 4 further includes a second arc-shaped plate 45, which is fixedly connected to the bottom of the threaded plate 612. A second short rod 47 is fixedly connected to the inner side of the second arc-shaped plate 45. A rotating plate 46 is rotatably connected to the outer periphery of the second short rod 47.

[0044] Furthermore, the molding frame 3 has a groove inside that corresponds to the size of the push plate 41, and the push plate 41 and the extrusion block 42 are slidably connected inside the molding frame 3. When the metal sheet is pressed and formed inside the molding frame 3, the extrusion block 42 can drive the push plate 41 to move upward, so that the push plate 41 can push the formed metal sheet, and the formed metal sheet can be quickly demolded.

[0045] Example 4

[0046] See Figure 1-7Furthermore, based on Embodiments 1, 2, and 3, the auxiliary mechanism 5 is further provided, including a pressing column 55. The pressing column 55 is fixedly connected to the bottom of the first moving plate 618. A telescopic rod 54 is fixedly connected to the top of the pressing column 55. A fourth spring 53 is sleeved around the telescopic rod 54. A fixing plate 52 is fixedly connected to the bottom of the telescopic rod 54. The fixing plate 52 is slidably connected to the inside of the pressing column 55. A squeezing cylinder 51 is fixedly connected to the bottom of the fixing plate 52. A sliding plate 56 is fixedly connected to the periphery of the fixing plate 52. A sliding ring 57 is fixedly connected to the periphery of the sliding plate 56.

[0047] Furthermore, the top of the fourth spring 53 is fixedly connected to the top of the inner part of the pressing column 55, and the bottom of the fourth spring 53 is fixedly connected to the top of the fixing plate 52. When the pressing column 55 does not press the metal sheet, the fourth spring 53 can drive the extrusion cylinder 51 to move downward through the fixing plate 52. The fixing plate 52 can drive the sliding ring 57 to move downward through the sliding plate 56, so that the extrusion cylinder 51 and the sliding ring 57 can demold the formed metal sheet and prevent the metal sheet from sticking to the outside of the pressing column 55.

[0048] In actual operation, when this device is used, the metal sheet to be pressed and formed is placed on top of the hollow block 627, and the pressing plate 626 is pressed down, so that the pressing plate 626 can move the limiting plate 623 downward, so that the limiting plate 623 can squeeze the snap-fit ​​plate 628, so that the snap-fit ​​plate 628 can limit the limiting plate 623, so that the pressing plate 626 can press the metal sheet. The cylinder 619 can drive the first moving plate 618 to move downward, so that the first moving plate 618 can drive the pressing column 55 to move downward, so that the pressing column 55 can press the metal sheet. The first moving plate 618 presses the pressing plate 6194 through the pressing rod 616. This causes the pressing plate 6194 to move the sliding rod 6193 downwards, which in turn causes the sliding rod 6193 to move the rack plate 614, which in turn causes the rack plate 614 to rotate the gear 613. The gear 613, through the threaded rod 611, causes the threaded plate 612 to move, which in turn causes the threaded plate 612, through the support plate 621, to move the hollow block 627. The hollow block 627 then moves the clamped metal sheet, allowing the metal sheet to be pressed and formed by the pressing column 55. When the metal sheet is being pressed and formed, as the hollow block 627 moves to the right, the second moving plate 629 is compressed by the forming frame 3, causing the second moving plate 629 to move the snap-fit ​​plate 628 away from the limiting plate 623, thus causing the second... Spring 624 can drive pressing plate 626 to move upward, preventing pressing plate 626 from pressing and fixing metal sheet. When threaded plate 612 moves to the right, threaded plate 612 can drive second short rod 47 to move via second arc plate 45, causing second short rod 47 to drive rotating plate 46 to rotate downward. Rotating plate 46 can drive extrusion block 42 and push plate 41 to move downward via first short rod 44 and first arc plate 43. After metal sheet is pressed and formed, when threaded plate 612 moves to the left, threaded plate 612 can drive second short rod 47 to move via second arc plate 45, causing second short rod 47 to drive rotating plate 46 to rotate. Rotating plate 46 can drive extrusion block 42 and push plate 41 to move downward via first short rod 44 and first arc plate 43. The arc plate 43 drives the extrusion block 42 and the push plate 41 to move, so that the push plate 41 can push the formed metal sheet, so that the metal sheet is separated from the inside of the forming frame 3, making it convenient for the staff to pick up. When the pressed metal sheet is attached to the outer surface of the pressing column 55, the fourth spring 53 can drive the telescopic rod 54 to move downward, so that the telescopic rod 54 can drive the extrusion cylinder 51 to move downward through the fixed plate 52. The telescopic rod 54 can drive the slide plate 56 to move through the fixed plate 52, so that the slide plate 56 can drive the sliding ring 57 to move downward, so that the extrusion cylinder 51 and the sliding ring 57 can push the formed metal sheet, so that the metal sheet slides off the outside of the pressing column 55, making it convenient for the staff to collect.
