Description

Technical Field

[0001] The invention relates to the field of green porcelain tape processing, and in particular to a green porcelain tape punching and half-cutting method and device for preventing hole-filling slurry from falling off. Background Art

[0002] Green tape is the foundation of the low-temperature co-fired ceramic process. The formation process of multi-layer ceramic products, including punching, filling, printing, lamination, static pressing and other pre-firing processes, are all carried out on the green tape. Therefore, the quality of the green tape will directly affect the performance of the low-temperature co-fired ceramic products.

[0003] When using a punching machine to perform half-cut punching on the filling area on the green porcelain tape, the existing technology uses a large punch to punch the cavity. As the cavity density increases, the stability of the green porcelain tape decreases. Affected by the vibration of the punching machine, the filling slurry is easily dragged off by the punch. Therefore, we propose a green porcelain tape half-cut punching method and device to avoid the filling slurry from falling off to solve the problem. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a method and device for punching and half-cutting a raw porcelain tape to prevent the filling slurry from falling off. This scheme can completely solve the problem of half-cutting and falling off of the filling slurry caused by the excessive density and poor stability of the raw porcelain tape openings by designing and adjusting the punching file and changing the punching method. This scheme is simple and easy to operate, has outstanding effects, and is conducive to improving the processing quality; and by fitting the large punch and the small punch together, when the small punch is needed, the inner punch group protrudes downward from the surface of the main punch to complete the punching work. When the large punch is needed, the inner punch group and the main punch are synchronously downward to complete the punching work. This not only saves the material cost of the processing tool, but is also more convenient to use, without the need to frequently adjust the punch. Moreover, through the cooperation of multiple punches of different sizes in the inner punch group, the cavity punched on the surface of the raw porcelain tape is gradually enlarged, which can further improve the stability of the processing state of the raw porcelain tape.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A method for punching and half-cutting a green porcelain tape to prevent the filling slurry from falling off includes a small punch, a large punch, and a green porcelain tape. The processing steps are as follows:

[0009] S1, first use a small punch to cover the filling hole and punch the green porcelain strip to process a small cavity with half-cut filling hole;

[0010] S2. Fit one side of the large punch to the side of the small cavity close to the filling hole, and then use the large punch to punch the green porcelain strip to form the required cavity;

[0011] By designing and adjusting the punching file and changing the punching method, the problem of half-cutting and falling off of the filling slurry caused by the excessive density and poor stability of the raw porcelain tape cavity can be completely solved. This solution is simple and easy to operate, has outstanding effects, and is conducive to improving processing quality.

[0012] The punch includes two groups of punch rods, one end of which is equipped with a connector. The other end is equipped with a main punch, and the upper connector is connected to a hydraulic device; an inner punch group is embedded in one end of the main punch, and the inner punch group and the main punch are symmetrically arranged up and down. An elastic connector is provided between the inner punch group and the main punch. The surface interface between the inner punch group and the main punch is flat, and a control mechanism is provided on the inner side of the upper inner punch group and the main punch; by fitting the large punch and the small punch together, when the small punch is needed, the inner punch group protrudes downward from the surface of the main punch to complete the punching work, and when the large punch is needed, the inner punch group and the main punch are synchronously moved downward to complete the punching work. This not only saves the material cost of the processing tool, but also makes it more convenient to use without the need to frequently replace the punch. Moreover, through the cooperation of multiple punches of different sizes in the inner punch group, the cavity punched on the surface of the green porcelain strip is gradually enlarged, which can further improve the stability of the processing state of the green porcelain strip.

[0013] Furthermore, the size of the large punch is proportionally enlarged to the size of the small punch, and the enlargement factor does not exceed five times. This makes the working state of the large punch more stable when it takes over the small punch to complete the stamping, which is effective in improving product quality.

[0014] Furthermore, the internal punch group includes an outer punch and an inner punch, the outer punch is slidably inserted in the main punch, and the inner punch is slidably inserted in the outer punch, one end of the main punch is provided with a through slot that penetrates into the inner punch, the punching rod passes through the through slot and is threadedly connected to the inner punch, the control mechanism includes a hollow cavity provided inside the upper punching rod, the inner wall of the hollow cavity is provided with two groups of extension openings extending to the inner wall of the through slot, the two groups of extension openings correspond to the outer punch and the inner punch respectively, a fixed block is slidably connected in the extension opening, and a fixed block is provided between the fixed block and the punching rod. An elastic pulling member, and the elastic pulling member limits the fixed card block in the punching rod, a central shaft is slidably connected in the hollow cavity, two push grooves corresponding to the fixed card block are provided on the outside of the central shaft, the side walls of the push groove are arranged in an inclined surface, and an adjustment slide groove is provided on the outside of the central shaft, and the adjustment slide groove is located above the main punch. The control mechanism also includes an external opening provided on the outside of the punching rod, and a rotating sleeve is connected to the opening of the external opening for rotation around the punching rod, and an adjusting slide rod penetrating the external opening and entering the adjustment slide groove is fixedly connected to the inner side of the rotating sleeve;

[0015] The elastic connecting part includes a mounting groove opened on the inner wall of the main punch and the outer punch, and a connecting spring is fixedly connected inside the mounting groove. The other end of the connecting spring in the main punch is connected to the outer punch, and the other end of the connecting spring in the outer punch is connected to the inner punch.

[0016] By splitting the inboard punch group into an outer punch and an inner punch, and using a central axis to control the working states of the outer punch, inner punch and main punch, when stamping starts, the punch rod pushes the outer punch downward, and the inner punch and main punch also move downward (at this time, the inner punch and main punch are only affected by gravity). When the three come into contact with the green porcelain strip, the inner punch and the main punch stop moving, while the outer punch continues to move downward under the push of the punch rod to complete the stamping work on the green porcelain strip and process a preliminary cavity. Then the main punch and the inboard punch group are reset, and the rotating sleeve is rotated to allow the outer punch group to move downward. The adjusting slide rod slides in the adjusting slide groove, controlling the downward movement of the center axis, so that the center axis pushes the fixed block out of the hollow cavity through the side wall slope of the pushing groove and is stuck in the extension mouth, thereby connecting the inner punch and the punch rod into one, completing the punching work together, which facilitates the adjustment of the punch state and is more convenient to use. At the same time, during the initial punching (the impact on the hole-filling slurry is the greatest at this time), a circle of punches that do not participate in the work surrounding the outside of the working punch can provide a certain support force for the raw porcelain tape and the hole-filling slurry, making its processing state more stable.

[0017] Furthermore, the width of the upper push groove is twice the width of the lower push groove. In this way, when the center axis moves downward, the punches at each level can perform stamping work one by one in order from bottom to top, making the entire working process smoother and more stable.

[0018] Furthermore, the rotating sleeve adopts a design that is light inside and heavy outside, which makes it easier to adjust.

[0019] Furthermore, the connection between the main punch and the outer punch, and the connection between the inner punch and the outer punch are both provided with a disassembly mechanism, and the disassembly mechanism includes a deflection slot provided on the connection surface of the outer punch and the inner punch, the deflection slot is arc-shaped, and the inner arc surface is communicated with the through slot, and the outer arc surface takes the axis of the punching rod as the center point, and the internal rotation of the deflection slot is connected with a deflection slider, the outer wall of the deflection slider is fitted with the deflection slot, and the inner wall is fitted with the punching rod, and the fitting surface of the deflection slider and the punching rod is provided with friction grooves, and an installation slot is provided inside the deflection slider, and the installation slot is also provided with the same arc shape as the deflection slider, and a disengagement port and a connection port communicated with the installation slot are provided on the surface of the deflection slider, and the disengagement port and the connection port are connected together, and the opening width of the disengagement port is the same as that of the installation slot, and the opening width of the connection port is the same as that of the installation slot. The cam is smaller than the width of the mounting slot and the disengagement port, and the internal sliding connection of the mounting slot is provided with a connecting slider, the width of the connecting slider is the same as the disengagement port, and the connecting slider is connected to the connecting spring. By arranging a disassembly mechanism between the outer punch, the inner punch and the connecting head, when one of the punches is damaged or fails, it is only necessary to rotate the punching rod to deflect the deflection slider in the deflection slot, and the connecting slider slides in the mounting slot without changing the coordinate position until it slides to the disengagement port. In this way, the connecting slider can be separated from the deflection slider at the disengagement port, and the inner and outer punches can also be separated. This facilitates the repair and maintenance of the main punch and the internal punch group, and is more convenient to disassemble and assemble. In the event of irreparable damage, only the damaged part can be replaced, thus saving the material cost of repair.

[0020] Furthermore, the friction lines between the deflection slider and the punching rod are in the shape of vertical stripes, so that the vertical movement of the punching rod during punching will not affect the deflection slider, thereby reducing the friction between the two at this time.

[0021] Furthermore, an adjusting disk is slidably sleeved on the outer side of the punching rod, and vertical stripes for sliding connection are set between the adjusting disk and the punching rod, so that the adjusting disk and the punching rod can move relative to each other in the vertical direction and move synchronously in the circumferential direction. The adjusting disk is rotatably connected to the top of the main punch, which makes it convenient to adjust the punching rod through the adjusting disk.

[0022] Furthermore, a locking slot is provided on the outer side of the adjusting disk, and a locking block corresponding to the locking slot is slidably connected to the top of the main punch. In this way, not only can the adjusting disk be fixed by the locking block to achieve the purpose of stabilizing the punching rod, but the locking slot can also increase the friction force on the surface of the adjusting disk, making it convenient to reduce the adjustment.

[0023] The cam is pressed against the top of the adjusting disc and is pressed against the guide rail when the adjusting disc is fixed, so that the cam is pressed against the guide rail and the guide rail is fixed to the adjusting disc.

[0024] 3. Beneficial effects

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] 1. This solution can completely solve the problem of half-cutting and falling off of the filling slurry caused by the excessive density and poor stability of the raw porcelain belt openings by designing and adjusting the punching files and changing the punching method. This solution is simple and easy to operate, has outstanding effects, and is conducive to improving the processing quality. By combining the large punch and the small punch together, when the small punch is needed, the internal punch group protrudes downward from the surface of the main punch to complete the punching work. When the large punch is needed, the internal punch group and the main punch are synchronously downward to complete the punching work. This not only saves the material cost of the processing tool, but is also more convenient to use. There is no need to frequently adjust the punch. Moreover, through the cooperation of multiple punches of different sizes in the internal punch group, the cavity punched on the surface of the raw porcelain belt is gradually enlarged, which can further improve the stability of the processing state of the raw porcelain belt.

[0027] 2. By splitting the inboard punch group into an outer punch and an inner punch, and using a central axis to control the working states of the outer punch, inner punch and main punch, when stamping starts, the punch rod pushes the outer punch downward, and the inner punch and main punch also move downward (at this time, the inner punch and main punch are only affected by gravity). When the three come into contact with the green porcelain strip, the inner punch and the main punch stop moving, while the outer punch continues to move downward under the push of the punch rod to complete the stamping work on the green porcelain strip and process a preliminary cavity. Then the main punch and the inboard punch group are reset, and the rotating sleeve is rotated. Let the adjusting slide bar slide in the adjusting slide groove, control the downward movement of the center axis, so that the center axis pushes the fixed block out of the hollow cavity through the side wall slope of the push groove and is stuck in the extension mouth, so that the inner punch and the punch rod are connected as one, and the punching work is completed together, which facilitates the adjustment of the punch state and is more convenient to use. At the same time, during the initial punching (the impact on the hole-filling slurry is the greatest at this time), a circle of punches that do not participate in the work surrounding the outside of the working punch can provide a certain support force for the raw porcelain tape and the hole-filling slurry, making its processing state more stable.

[0028] 3. By setting a disassembly mechanism between the outer punch, the inner punch and the connecting head, when one of the punches is damaged or fails, it is only necessary to rotate the punch rod to deflect the deflection slider in the deflection slide groove. The coordinate position of the connecting slider remains unchanged and slides in the installation slide groove until it slides to the disengagement port. In this way, the connecting slider can be separated from the deflection slider at the disengagement port, and the inner and outer punches can also be separated. This facilitates the repair and maintenance of the main punch and the internal punch group, and is more convenient for disassembly and assembly. In the event of irreparable damage, only the damaged part can be replaced, which saves the material cost of repair.

[0029] 4. By fixing the rotating sleeve and the adjusting disk so that the rotating sleeve is in the receiving slot, the compression spring pushes the card rod into the fixed card slot to fix the rotating sleeve on the adjusting disk. This ensures that the interference to the rotating sleeve is reduced and the working state is more stable. When adjustment is needed, the rotating sleeve is moved with force. The card rod is squeezed and moves into the compression slot to compress the compression spring (the rotating sleeve and the center axis will not be subject to too much external force interference, so the force required to compress the compression spring is not large), so that the rotating sleeve can be deflected to a certain angle, allowing the card rod to enter the fixed card slot of the next month.

[0047] Example:

[0048] See also Figure 1 A method for punching and half-cutting a green porcelain tape to prevent the filling slurry from falling off includes a small punch, a large punch, and a green porcelain tape. The processing steps are as follows:

[0049] S1, first use a small punch to cover the filling hole and punch the green porcelain strip to process a small cavity with half-cut filling hole;

[0050] S2. Fit one side of the large punch to the side of the small cavity close to the filling hole, and then use the large punch to punch the green porcelain strip to form the required cavity;

[0051] By designing and adjusting the punching file and changing the punching method, the problem of half-cutting and falling off of the filling slurry caused by the excessive density and poor stability of the raw porcelain tape cavity can be completely solved. This solution is simple and easy to operate, has outstanding effects, and is conducive to improving processing quality.

[0052] The size of the large punch is proportionally enlarged to the size of the small punch, and the enlargement factor does not exceed five times. This makes the working state of the large punch more stable when it takes over the small punch to complete the stamping, which is helpful in improving product quality.

[0053] See also Figure 2The punch includes two sets of punching rods 1, and one end of the punching rod 1 is equipped with a connecting head 2. The other end is equipped with a main punch 3, and the upper connecting head 2 is connected to the hydraulic equipment; one end of the main punch 3 is embedded with an internal punch group 4, the internal punch group 4 and the main punch 3 are symmetrically arranged up and down, and an elastic connecting piece is arranged between the internal punch group 4 and the main punch 3, the surface interface of the internal punch group 4 and the main punch 3 is flat, and a control mechanism 5 is arranged on the inner side of the upper internal punch group 4 and the main punch 3; by fitting the large punch and the small punch together, when the small punch is needed to work, the internal punch group 4 protrudes downward from the surface of the main punch 3 to complete the stamping work, and when the large punch is needed, the internal punch group 4 and the main punch 3 are synchronously moved downward to complete the stamping work, which not only saves the material cost of the processing tool, but also is more convenient to use, without the need to frequently replace the punch, and through the cooperation of multiple punches of different sizes of the internal punch group 4, the cavity punched on the surface of the raw porcelain strip is gradually enlarged little by little, which can further improve the stability of the processing state of the raw porcelain strip.

[0054] See also Figures 2 to 11 The internal punch group 4 includes an outer punch 41 and an inner punch 42. The outer punch 41 is slidably inserted in the main punch 3, and the inner punch 42 is slidably inserted in the outer punch 41. One end of the main punch 3 is provided with a through groove that penetrates into the inner punch 42. The punching rod 1 is threadedly connected to the inner punch 42 through the through groove. The control mechanism 5 includes a hollow cavity 51 opened inside the upper punch rod 1. The inner wall of the hollow cavity 51 is provided with two groups of extension openings 52 extending to the inner wall of the through groove. The two groups of extension openings 52 correspond to the outer punch 41 and the inner punch 42 respectively. A fixed block 53 is slidably connected in the extension opening 52, and an elastic force is set between the fixed block 53 and the punching rod 1. Pulling piece, and the elastic pulling piece limits the fixed block 53 in the punching rod 1, a central shaft 54 ​​is slidably connected in the hollow cavity 51, and two push grooves 55 corresponding to the fixed block 53 are provided on the outside of the central shaft 54, and the side walls of the push groove 55 are arranged in an inclined surface. An adjusting slide 56 is also provided on the outside of the central shaft 54, and the adjusting slide 56 is located above the main punch 3. The control mechanism 5 also includes an external opening 57 provided on the outside of the punching rod 1, and a rotating sleeve 58 is connected to the opening of the external opening 57 for rotation around the punching rod 1. The inner side of the rotating sleeve 58 is fixedly connected with an adjusting slide rod 59 that passes through the external opening 57 and enters the adjusting slide groove 56;

[0055] The width of the upper push groove 55 is twice the width of the lower push groove 55. In this way, when the central axis 54 moves downward, the punches at each level can be pressed one by one in the order from bottom to top, making the entire working process smoother and more stable.

[0056] The elastic connecting part includes a mounting groove 510 opened on the inner wall of the main punch 3 and the outer punch 41, and a connecting spring 511 is fixedly connected inside the mounting groove 510. The other end of the connecting spring 511 in the main punch 3 is connected to the outer punch 41, and the other end of the connecting spring 511 in the outer punch 41 is connected to the inner punch 42.

[0057] When punching starts, the punch rod 1 pushes the outer punch 41 downward, and the inner punch 42 and the main punch 3 also move downward (at this time, the inner punch 42 and the main punch 3 are only affected by gravity). When the three come into contact with the green porcelain strip, the inner punch 42 and the main punch 3 stop moving, and the outer punch 41 continues to move downward under the push of the punch rod 1 to complete the punching work on the green porcelain strip and process a preliminary cavity. Then the main punch 3 and the inner punch group 4 are reset, and the adjusting slide 59 is made to slide in the adjusting slide groove 56 by rotating the rotating sleeve 58 to control the center axis 54. Move downward so that the central shaft 54 ​​pushes the lower fixed block 53 out of the hollow cavity 51 through the side wall slope of the lower push groove 55 and snaps it into the extension opening 52. In this way, the inner punch 42 and the punching rod 1 are connected as one, and the stamping work is completed together. Finally, adjust the rotating sleeve 58 again to move the central shaft 54 ​​downward, and push the upper fixed block 53 out of the hollow cavity 51 through the side wall slope of the upper push groove 55 and snap it into the extension opening 52. In this way, the main punch 3 and the punching rod 1 are connected as one, and the stamping work is completed together to process the specified hole cavity.

[0058] The rotating sleeve 58 is designed to be light inside and heavy outside, so that the center of gravity of the rotating sleeve 58 is moved outward, making it easier to adjust.

[0059] See also Figures 9 to 13 The connection between the main punch 3 and the outer punch 41 and the connection between the inner punch 42 and the outer punch 41 are both provided with a disassembly mechanism 6. The disassembly mechanism 6 includes a deflection slide 61 provided on the connection surface of the outer punch 41 and the inner punch 42. The deflection slide 61 is arc-shaped, and the inner arc surface is connected to the through groove. The outer arc surface takes the axis of the punching rod 1 as the center point. The internal rotation of the deflection slide 61 is connected with a deflection slider 62. The outer wall of the deflection slider 62 is in contact with the deflection slide 61, and the inner wall is in contact with the punching rod 1. The contact surface of the deflection slider 62 and the punching rod 1 is provided with friction lines. The deflection slider 62 An installation slot 63 is provided inside the deflection slider 62, and the installation slot 63 is also provided in the same arc shape as the deflection slider 62. A disengagement port 64 and a connection port 65 are provided on the surface of the deflection slider 62, which are communicated with the installation slot 63. The disengagement port 64 and the connection port 65 are communicated with each other. The opening width of the disengagement port 64 is the same as that of the installation slot 63, while the opening width of the connection port 65 is smaller than the width of the installation slot 63 and the disengagement port 64. A connecting slider 66 is slidably connected inside the installation slot 63. The width of the connecting slider 66 is the same as that of the disengagement port 64, and the connecting slider 66 is connected to the connecting spring 511.

[0060] When one of the main punch 3, the outer punch 41, and the inner punch 42 is damaged or fails, it is only necessary to rotate the punch rod 1 to deflect the deflection slider 62 in the deflection slot 61, and the connecting slider 66 slides in the installation slot 63 while the coordinate position remains unchanged until it slides to the disengagement port 64. Figure 13 As shown, the connecting slider 66 can be separated from the deflection slider 62 from the disengagement port 64, so that the inner and outer punches can also be separated. During assembly, the small punch is inserted into the large punch, and the connecting slider 66 enters the fixed block 53 from the disengagement port 64. Then, the punching rod 1 is rotated to drive the deflection slider 62 to deflect, and the connecting slider 66 slides in the installation slot 63 to the connecting port 65. Figure 12 As shown, the connecting slider 66 is locked in the installation slot 63, and the large and small punches are also connected via the connecting spring 511.

[0061] The friction lines between the deflection slider 62 and the punching rod 1 are in the shape of vertical stripes, so that the vertical movement of the punching rod 1 during punching will not affect the deflection slider 62, reducing the friction between the two at this time; the outer side of the punching rod 1 is slidably sleeved with an adjusting disk 67, and vertical stripes with sliding connection are set between the adjusting disk 67 and the punching rod 1, so that the adjusting disk 67 and the punching rod 1 can make relative movement in the vertical direction, and move synchronously in the circumferential direction. The adjusting disk 67 is rotatably connected to the top of the main punch 3, which is convenient for adjusting the punching rod 1 through the adjusting disk 67; a locking slot is provided on the outer side of the adjusting disk 67, and the top of the main punch 3 is slidably connected with a locking block 68 corresponding to the locking slot, so that not only can the adjusting disk 67 be fixed by the locking block 68 to achieve the purpose of stabilizing the punching rod 1, but the locking slot can also increase the friction force on the surface of the adjusting disk 67, which is convenient for reducing adjustment.

[0062] See also Figures 9 to 11, a pushing mechanism 7 is provided between the adjusting disk 67 and the rotating sleeve 58, the pushing mechanism 7 includes a receiving groove 71 provided on the top of the adjusting disk 67, the rotating sleeve 58 is received in the receiving groove 71, the inner wall of the receiving groove 71 is provided with three sets of fixed slots 72, the outer wall of the rotating sleeve 58 is provided with a compression groove 73 corresponding to the fixed slot 72, the inner wall of the compression groove 73 is fixedly connected with a compression spring 74, the other end of the compression spring 74 is fixedly connected with a card rod 75 extending into the fixed slot 72, the card rod 75 extends as the fixed slot 72 part is set in an arc shape, by fixing the rotating sleeve 58 to the adjusting disk 67 The locking mechanism 75 is fixed so that the rotating sleeve 58 is in the receiving groove 71 and the compression spring 74 pushes the card rod 75 into the fixed card groove 72 to fix the rotating sleeve 58 on the adjusting disk 67. In this way, the interference of the rotating sleeve 58 is reduced and the working state is more stable. When adjustment is needed, the rotating sleeve 58 is moved with force, and the card rod 75 is squeezed and moves into the compression groove 73 to compress the compression spring 74 (the rotating sleeve 58 and the central shaft 54 ​​are not subject to too much external interference, so the force required to compress the compression spring 74 is not large), so that the rotating sleeve 58 can be deflected by a certain angle, allowing the card rod 75 to enter the fixed card groove 72 of the next month.
