Description

Technical Field

[0001] This application relates to the field of blind plate production equipment, and in particular to a blind plate forming and compaction device. Background Art

[0002] During the steelmaking process, when the molten steel stops casting, in order to prevent the molten steel from overflowing, a blind plate is needed for plugging. The blind plate is made of a variety of refractory materials. The preparation process is to mix a variety of refractory materials into a blank, then place the corresponding blind plate mold on the compaction device, pour the blank into the mold, start the compaction device, remove the gas in the blank, and improve the density of the product.

[0003] The current compaction device usually includes a driving component, a vibrating plate and a pressing component. The staff places the mold on the vibrating plate, then controls the pressing component to press the mold against the vibrating plate from above, and then starts the driving component to make the vibrating plate vibrate, so as to vibrate out the gas in the blank.

[0004] However, the existing compaction device can only fix the mold in the vertical direction. During the vibration process, the mold is likely to move horizontally, causing one end of the mold to break away from the pressing of the pressing component, affecting the forming and compaction effect of the blank. Utility Model Content

[0005] In order to enhance the stability of the mold and improve the forming and compaction effect of the blank, this application provides a blind plate forming and compaction device.

[0006] A blind plate forming and compaction device provided by this application adopts the following technical solutions:

[0007] A blind plate forming and compaction device includes a driving component and a vibrating plate, and further includes a pressing component, a clamping component and two limiting components. The driving component is arranged at the bottom of the vibrating plate. One end of the top of the vibrating plate is provided with a mounting plate. The pressing component includes a power component and a pressing plate. The power component is arranged on the mounting plate and drives the pressing plate to move in the vertical direction. The pressing plate is located above the vibrating plate. The clamping component is arranged on the vibrating plate. The clamping component includes a moving component and two clamping plates. The moving component drives the two clamping plates to approach or move away from each other. The two limiting components correspond to the two clamping plates one by one. The limiting component is arranged on the clamping plate.

[0008] By adopting the above technical solution, place the mold on the vibrating plate, start the moving member to drive the two clamping plates to move towards each other to clamp the mold, then control the power member to drive the pressing plate to drop from above, so that the mold is pressed tightly against the vibrating plate, and adjust the limiting component to restrict the mold from moving horizontally. Then add the blank into the mold, start the driving component to drive the vibrating plate to vibrate, and discharge the gas in the blank. Since the mold is fixed both vertically and horizontally, the stability of the mold during the compaction process can be greatly enhanced.

[0009] Optionally, the moving member includes a driving motor, a driving gear and two moving racks. The driving motor is arranged on the vibrating plate, the driving gear is fixedly connected to the output shaft of the driving motor, the two moving racks correspond to the two clamping plates one by one, the moving rack is fixedly connected to the side wall of the clamping plate, and is meshed with the driving gear.

[0010] By adopting the above technical solution, after placing the mold on the vibrating plate, start the driving motor. The output shaft of the driving motor drives the driving gear to rotate, driving the two moving racks to move towards each other. The two clamping plates move along with the corresponding moving racks to clamp the mold, and the operation is simple.

[0011] Optionally, the limiting component includes a limiting plate and a plurality of positioning pins. A sliding groove is formed on the side wall of the clamping plate close to the center line of the vibrating plate. The limiting plate is slidably connected in the sliding groove. A plurality of through fixing holes are formed on the side wall of the sliding groove away from the vibrating plate. The plurality of positioning pins correspond to the plurality of fixing holes one by one. The positioning pin is inserted into the fixing hole, and a positioning groove for accommodating the positioning pin to be embedded is formed on the limiting plate.

[0012] By adopting the above technical solution, after the two clamping plates fix the mold from the opposite sides, move the limiting plate to limit the mold from another direction. When the limiting plate moves to a suitable position, insert the positioning pin in the corresponding fixing hole into the positioning groove to complete the fixing of the limiting plate, so that the mold cannot move significantly horizontally when vibrating.

[0013] Optionally, a pulling plate is fixedly connected to one end of the positioning pin away from the vibrating plate, a return spring is arranged on the pulling plate, one end of the return spring is fixedly connected to the pulling plate, and the other end is fixedly connected to the clamping plate.

[0014] By adopting the above technical solution, when moving the movable limiting plate, the pulling plate needs to be pulled upward. When the limiting plate moves to a suitable position, the positioning groove is adjusted to communicate with the corresponding fixing hole. After releasing the pulling plate, the positioning pin is embedded in the positioning groove under the elastic action of the reset spring. Even if the vibration amplitude of the vibrating plate is large, the positioning pin can still remain embedded in the positioning groove, enhancing the stability of the limiting plate.

[0015] Optionally, the power member includes a rotating rod. A moving groove is formed in the side wall of the mounting plate close to the pressing plate. The side wall of the pressing plate is attached to the inner wall of the moving groove. One end of the rotating rod penetrates and is rotatably connected to the side wall of the moving groove, and the other end penetrates and is threadedly connected to the pressing plate.

[0016] By adopting the above technical solution, after the two clamping plates clamp and fix the mold, rotate the rotating rod to drive the pressing plate to move downward in the moving groove along the vertical direction, and press the mold against the vibrating plate.

[0017] Optionally, the power member further includes a ratchet wheel, a ratchet pawl and a torsion spring. The ratchet wheel is coaxially and fixedly connected to the rotating rod. The ratchet pawl is rotatably connected to the top of the mounting plate and is embedded in the tooth groove of the ratchet wheel. One end of the torsion spring abuts against the mounting plate, and the other end abuts against the side wall of the ratchet pawl.

[0018] By adopting the above technical solution, when the staff rotates the rotating rod to drive the pressing plate to press the mold tightly, since the ratchet pawl is embedded in the tooth groove of the ratchet wheel, the rotating rod cannot rotate in the reverse direction. During the vibration of the vibrating plate, the pressing plate always presses the mold tightly, further improving the stability of the mold.

[0019] Optionally, a handwheel is coaxially and fixedly connected to the top of the rotating rod.

[0020] By adopting the above technical solution, the staff rotates the handwheel to drive the rotating rod to rotate, which is labor-saving and convenient to operate.

[0021] Optionally, support columns are arranged at the bottom of the vibrating plate, and buffer springs are arranged between the vibrating plate and the support columns.

[0022] By adopting the above technical solution, during the vibration, the buffer spring can reduce the impact of the vibrating plate on the support column, ensuring the smooth operation of the vibrating compaction device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After placing the mold on the vibrating plate, start the driving motor. The output shaft of the driving motor drives the driving gear to rotate, driving the two moving racks to move towards each other. The two clamping plates move along with the corresponding moving racks to clamp the mold, and the operation is simple;

[0025] 2. When moving the limit plate, the pull plate needs to be pulled upward. When the limit plate moves to a suitable position, the positioning groove is adjusted to communicate with the corresponding fixing hole, and then the pull plate is released. Under the elastic action of the return spring, the positioning pin is embedded in the positioning groove. Even if the vibration amplitude of the vibrating plate is large, the positioning pin can still remain embedded in the positioning groove, enhancing the stability of the limit plate;

[0026] 3. After the staff rotates the rotating rod to drive the pressing plate to press the mold tightly, since the ratchet pawl is embedded in the tooth groove of the ratchet wheel, the rotating rod cannot rotate in the reverse direction. During the vibration of the vibrating plate, the pressing plate always presses the mold tightly, further improving the stability of the mold. Description of the Drawings

[0033] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings for a more detailed description.

[0034] Refer to Figure 1, a compaction device for blind plate forming disclosed in an embodiment of the present application includes a driving assembly 1, a vibrating plate 2, a pressing assembly 3, a clamping assembly 4, and two limiting assemblies 5. In this embodiment, the driving assembly 1 is a vibrating motor, which is fixedly installed at the bottom of the vibrating plate 2. The vibrating plate 2 is arranged horizontally. Buffer springs 6 are fixedly installed at the corners of the bottom of the vibrating plate 2. The bottom end of the buffer spring 6 is fixedly connected to a support column 7. An expansion rod is inserted into the buffer spring 6. That is to say, one end of the expansion rod is fixedly connected to the bottom of the vibrating plate 2, and the other end is fixedly connected to the top end of the support column 7. The pressing assembly 3 is arranged on the top of the vibrating plate 2, the clamping assembly 4 is arranged on the vibrating plate 2, and the two limiting assemblies 5 are arranged on the clamping assembly 4.

[0035] Referring to Figure 2 and Figure 3 , the pressing assembly 3 includes a power member 31 and a pressing plate 32. The power member 31 includes a rotating rod 311, a ratchet wheel 312, a ratchet pawl 313, and a torsion spring 314. One end of the top of the vibrating plate 2 is fixedly installed vertically with a mounting plate 21. A moving groove 211 is formed on the side wall of the mounting plate 21 close to the center line of the vibrating plate 2. The rotating rod 311 is inserted vertically and rotatably connected to the side wall of the moving groove 211. The opposite side walls of the pressing plate 32 in the horizontal direction are in contact with the inner wall of the moving groove 211. The rotating rod 311 is inserted and threadedly connected to the pressing plate 32. It should be noted that a part of the rotating rod 311 is exposed above the mounting plate 21, and a hand wheel 8 is fixedly connected to the top end of the rotating rod 311. The ratchet wheel 312 is coaxially and fixedly connected to the rotating rod 311 and is located above the mounting plate 21. The ratchet pawl 313 is rotatably connected to the top of the mounting plate 21 and is embedded in the tooth groove of the ratchet wheel 312. The torsion spring 314 is installed on the top of the mounting plate 21, one end of which is fixedly connected to the side wall of the ratchet pawl 313, and the other end is fixedly connected to the mounting plate 21.

[0036] After the mold is placed on the top of the vibrating plate 2, the operator rotates the hand wheel 8. The hand wheel 8 drives the rotating rod 311 to rotate, driving the pressing plate 32 to move downward vertically in the moving groove 211, pressing the mold against the top of the vibrating plate 2. Since the ratchet pawl 313 is always embedded in the tooth groove of the ratchet wheel 312 under the elastic action of the torsion spring 314, the rotating rod 311 cannot rotate in the reverse direction. During the vibration of the vibrating plate 2, the pressing plate 32 always presses the mold tightly, improving the stability of the mold.

[0037] Referring to Figure 1 and Figure 2, the clamping assembly 4 includes a moving member 41 and two clamping plates 42. The moving member 41 includes a driving motor 411, a driving gear 412, and two moving racks 413. The driving motor 411 is fixedly installed on the side wall of the vibrating plate 2. The output shaft of the driving motor 411 is fixedly connected to the driving gear 412. The two moving racks 413 are respectively meshed and connected to the top and bottom of the driving gear 412. The two moving racks 413 correspond to the two clamping plates 42 one by one. The moving rack 413 is fixedly connected to the side wall of the clamping plate 42 close to the center line of the vibrating plate 2. Two sliding grooves are formed at the top of the vibrating plate 2, and the two clamping plates 42 are respectively slidably connected in the sliding grooves along the horizontal direction.

[0038] The mold is placed on the top of the vibrating plate 2. The driving motor 411 is started. The output shaft of the driving motor 411 drives the driving gear 412 to rotate, driving the two moving racks 413 to move towards each other. The two clamping plates 42 move along with the moving racks 413 to clamp the opposite sides of the mold.

[0039] Refer to Figure 4 and Figure 5 , the two limiting assemblies 5 correspond to the two clamping plates 42 one by one. Each limiting assembly 5 includes a limiting plate 51 and a plurality of positioning pins 52. A sliding groove 421 is formed on the side wall of the clamping plate 42 close to the center line of the vibrating plate 2 along its own extension direction. The limiting plate 51 is slidably connected in the sliding groove 421. It should be noted that the limiting plate 51 is located above the vibrating plate 2. A plurality of through fixing holes 422 are formed on the side wall of the sliding groove 421 away from the support column 7 along its own extension direction. The plurality of positioning pins 52 correspond to the plurality of fixing holes 422 one by one. The positioning pins 52 are inserted into the fixing holes 422. A positioning groove 511 capable of accommodating a part of the positioning pin 52 to be embedded is formed at the top of the limiting plate 51.

[0040] It should be added that a pulling plate 521 is fixedly connected to the top end of the positioning pin 52. A return spring 522 is fixedly connected to the pulling plate 521. One end of the return spring 522 is fixedly connected to the bottom of the pulling plate 521, and the other end is fixedly connected to the top of the clamping plate 42.

[0041] After the pressing assembly 3 and the clamping assembly 4 fix the mold, slide the limiting plate 51 to a suitable position. When the limiting plate 51 passes through the fixing hole 422, the staff needs to pull up the pulling plate 521 to lift the positioning pin 52. When the limiting plate 51 no longer needs to move, align the positioning groove 511 with the closest fixing hole 422, release the pulling plate 521, and the positioning pin 52 is embedded in the positioning groove 511 under the elastic action of the return spring 522. Thus, even if the vibration amplitude of the vibrating plate 2 is large, the positioning pin 52 can still be kept embedded in the positioning groove 511, further enhancing the stability of the limiting plate 51.

[0042] The implementation principle of a compaction device for blind plate forming in an embodiment of this application is as follows: The staff places the mold on the top of the vibration plate 2. First, start the driving motor 411. The output shaft of the driving motor 411 drives the driving gear 412 to rotate, driving the two moving racks 413 to move towards each other. The two clamping plates 42 move along with the moving racks 413 to clamp the opposite sides of the mold. Then the staff rotates the handwheel 8. The handwheel 8 drives the rotating rod 311 to rotate, driving the pressing plate 32 to move downward along the vertical direction in the moving groove 211 to press the mold tightly against the top of the vibration plate 2. Then move the limiting plate 51 to a suitable position and insert the positioning pin 52 into the positioning groove 511 to fix the mold from multiple directions, greatly enhancing the stability of the mold and improving the compaction effect of the blank during forming.

[0043] After the blank compaction is completed, the staff first pulls the pull plate 521 to lift the positioning pin 52 and moves the limiting plate 51 away from the mold; then rotates the pawl 313 to disengage it from the tooth groove of the ratchet wheel 312, rotates the handwheel 8 to drive the pressing plate 32 to lift; finally, start the driving motor 411 again to make the driving gear 412 rotate in the reverse direction, driving the two clamping plates 42 to move away from each other along with the moving racks 413, and the staff can take out the mold at this time.

[0044] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
