Description

Technical Field

[0001] This utility model relates to the field of ceramic fiber sealing gasket processing technology, specifically a cutting device for preparing ceramic fiber sealing gaskets. Background Technology

[0002] Ceramic fiber sealing gaskets are key materials for solving sealing and heat insulation problems in high-temperature environments, and have excellent temperature resistance, heat insulation, flexibility and chemical stability.

[0003] Utility model patent CN220428638U discloses a device for separating a gasket and cutting waste. The cutting component cuts the ceramic fiber sealing material. After cutting, a second telescopic rod is activated, moving the support frame upwards. This causes the waste generated during the cutting process to move upwards along the cutting component, effectively separating the waste from the ceramic fiber sealing gasket. This structure is suitable for cutting equipment with a cutting blade. However, common CNC laser cutting / cutting equipment requires sufficient blade travel space, therefore the above device is not compatible with CNC laser cutting / cutting equipment.

[0004] Therefore, there is an urgent need to design a cutting device that is suitable for CNC laser cutting processes and can separate the liner and waste material. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting device for preparing ceramic fiber sealing gaskets, thereby overcoming the aforementioned shortcomings in the prior art. To achieve the above objective, this utility model provides the following technical solution: A cutting device for preparing ceramic fiber sealing gaskets, comprising: a frame structure including a layout plate and mounting holes, the layout plate being laid on the ground and the mounting holes being formed in the layout plate; a separation component including a mounting plate, perforations, and a punching rod, the mounting plates being detachably connected, the mounting plate having several perforations, and a punching rod being elastically slidably connected in each perforation; an elastic cloth connected to the layout plate and located on the downward movement path of the punching rod; a clamping component for fixing the fiber pad located on the elastic cloth to the frame structure; and a reciprocating component including a drive unit and a push rod, the upper end of the punching rod being located on the movement path of the push rod, and the drive unit for driving the push rod to move along the horizontal direction of the layout plate.

[0006] Preferably, the mounting hole and the mounting plate are magnetically attracted to each other.

[0007] Preferably, both ends of the piercing rod are thicker than the middle rod, and the spring is located on the upper side of the mounting plate.

[0008] Preferably, a pad is detachably connected to the push rod, the contact surface between the pad and the stick is an inclined surface, and the contact surface between the stick and the pad is an arc surface.

[0009] Preferably, the drive unit includes a motor and a lead screw. The motor is mounted on the arrangement plate, the lead screw is fixedly connected to the output shaft of the motor, and the push rod is sleeved on the lead screw through a threaded structure.

[0010] Preferably, the clamping component is a G-type clamp.

[0011] Preferably, it also includes a supporting shell, a first conveyor belt and a second conveyor belt, the supporting shell and the arrangement plate are fixed, the first conveyor belt and the second conveyor belt are installed on the supporting shell, and the highest surface of the first conveyor belt and the second conveyor belt is not higher than the highest surface of the laser cutting machine tool worktable.

[0012] Preferably, conveyor belt one is located on both sides of conveyor belt two, and the conveying path of conveyor belt one is longer than the conveying path of conveyor belt two, with conveyor belt two located at the entry end of the elastic fabric.

[0013] The beneficial effects of this utility model are as follows: 1. The introduction of a separation component and G-clamp solves the key problem of the inability to automatically unload the pad after laser cutting, thus achieving reliable separation of the pad.

[0014] 2. Using a separation component for mechanical separation, the operator only needs to perform clamping and removal operations from a safe position, which significantly reduces the risk of burns and cuts to the operator, while also reducing the possibility of pad deformation, tearing or edge damage due to improper manual operation, thus improving the yield rate.

[0015] 3. CNC laser machine tools can operate synchronously on the worktable and the separation component, achieving parallel cutting and separation. This significantly shortens the time from the completion of cutting to the removal of a single pad, improving overall production cycle time and efficiency.

[0016] 4. Clamping components, such as the G-clamp, effectively prevent the fiber pad from moving or shifting during the puncturing process. The vertically downward-pressing puncture rod can precisely apply pressure to the cutting line, ensuring that the pad is completely and accurately separated from the waste along the predetermined contour, maintaining the accuracy of its shape and dimensions.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This equipment is located behind the output position of the CNC laser cutting machine, specifically at the machine's output port. It introduces laser-cut fiber pads and separates the padding from the waste padding along the cutting path, aiming to obtain the padding in a concentrated and efficient manner. The entire equipment's physical space and processing sequence are located behind the CNC laser cutting machine, resulting in a stable cycle time and higher productivity.

[0027] like Figures 1-6 The entire device consists of a frame structure 1, a separation component 2, an elastic cloth 3, and a reciprocating component 4.

[0028] The frame structure 1 serves as the overall support structure, supporting several components such as the separation component 2, the elastic fabric 3, and the reciprocating component 4. The frame component 1 is generally placed on the ground and includes a mounting plate 11 with several designed mounting holes 12. In this embodiment, the mounting holes 12 are preferably hexagonal structures with embedded slots. The slots are countersunk holes on the six sides of the hexagon, and the surfaces communicating with the mounting holes 12 are stepped surfaces.

[0029] The separation component 2 is installed in the mounting hole 12 and is used in conjunction with the elastic cloth 3. It includes a mounting plate 21, perforations 22, and a poking rod 23. The mounting plate 21 and the mounting hole 12 are installed with a gap. The mounting plate 21 has several perforations 22 with designed positions. Each perforation 22 is elastically slidably connected to the poking rod 23 by a spring. The poking rod 23 moves up and down along the Z-axis.

[0030] Preferably, the perforations 22 on the mounting plate 21 are arranged in a star pattern.

[0031] Preferably, the perforations 22 on the mounting plate 21 are arranged in a matrix.

[0032] Preferably, the piercing rod 23 is dumbbell-shaped with thicker ends and a thinner middle section. The diameter of the through hole 22 is smaller than the diameter of the two ends of the piercing rod 23 and transitions with the middle section of the rod. This design makes it easier for the operator to lift the mounting plate 21 to separate the mounting hole 12 and the mounting plate 21 when holding the piercing rod 23.

[0033] Furthermore, one of the large ends of the puncture rod 23 is integrally formed with the rod body, while the other large end is connected to the rod body by a thread to facilitate the installation of the spring.

[0034] In this embodiment, the mounting plate 21 can be manufactured using an additive manufacturing method, such as 3D printing technology. This method can be combined with a flexible perforation 22 placement design to reduce the production cost of each mounting plate 21.

[0035] In short, if the gasket being processed is a straight strip, then a matrix perforation design 22 is selected; if the gasket being processed is an arc, then an arc-shaped perforation design 22 is selected, and so on.

[0036] Preferably, magnets are bonded to the clips on the six sides of the mounting plate 21, and magnets are also provided in the slots on the six sides of the mounting hole 12. The two types of magnets attract each other, thereby limiting the position of the mounting plate 21 when the operator places the mounting plate 21 into the mounting hole 12.

[0037] The elastic cloth 3 is an elastic tension layer connected to the arrangement plate 11. The connection method can be clamping or pressing with fasteners after passing through. Since this installation method is common, it will not be described in detail. The presence of the elastic cloth 3 can support the fiber pad introduced into the frame structure 1 on the one hand, and on the other hand, it can form a certain clearance space while being frequently squeezed by the downward movement of the piercing rod 23, so that the piercing rod 23 can pierce the pad off the waste material.

[0038] Preferably, the material of the elastic cloth 3 is silicone rubber.

[0039] The reciprocating assembly 4 is the power component that drives the punching rod 23 to move frequently and in batches. It adopts a common slide table structure or other structures with reciprocating driving capability. In this embodiment, a slide table structure is selected, including a motor 41, a lead screw 42, and a push rod 43. The motor 41 is installed on one side of the arrangement plate 11 and electrically connected to the mains power. The installation method of the motor 41 is common and will not be described in detail. The output shaft of the motor 41 is fixedly connected to one end of the lead screw 42 through a flange. The other end of the lead screw 42 is rotatably connected to the arrangement plate 11 through a bearing. The push rod 43 is threadedly connected to the lead screw 42. The two ends of the push rod 43 are slidably connected to the side wall of the arrangement plate 11. By turning on the motor 41, the motor 41 can be rotated forward / reverse to drive the push rod 43 to reciprocate along the axial direction of the lead screw 42 through the threaded structure, thereby squeezing the punching rod 23 on the moving path. This causes the squeezed punching rod 23 to overcome the elastic force and move downward to punch the pad located on the elastic cloth 3.

[0040] Preferably, a pad 44 is detachably connected to the push rod 43 by bolts. Depending on the required stroke of the sting rod 23, pads 44 of different heights can be selected. Under the premise of not exceeding the maximum displacement of the sting rod 23, a higher pad 44 can drive the sting rod 23 to move downward by a greater displacement.

[0041] The contact surface between the pad 44 and the piercing rod 23 is an inclined surface, while the contact surface between the piercing rod 23 and the pad 44 is an arc surface.

[0042] Based on the above structure, considering the need to fix the fiber pad that moves onto the elastic cloth 3, a common G-type clamp is used to clamp the side edge of the fiber pad that has fully entered the elastic cloth 3 onto the arrangement plate 11, thereby controlling the tension of the fiber pad and reducing the probability of the fiber pad being torn due to excessive force during the puncturing process.

[0043] Preferably, an automated pneumatic clamping mechanism controlled by an automated system can be used to replace the G-type clamp, thereby improving the automation level of the entire equipment.

[0044] Based on the above design, a conveying assembly 5 is also designed to guide the fiber pad output by the machine tool into the elastic cloth 3. This assembly includes a first conveyor belt 52 and a second conveyor belt 53 installed on the support housing 51. The support housing 51 and the arrangement plate 11 are fixed. The two first conveyor belts 52 are respectively installed on both sides of the elastic cloth 3. The highest conveying surface of the first conveyor belt 52 is slightly higher than the elastic cloth 3. A second conveyor belt 53 is also designed between the two first conveyor belts 52 and on one side of the inlet end of the elastic cloth 3. The second conveyor belt 53 is also installed on the support housing 51. The second conveyor belt 53 and the corresponding first conveyor belt 52 are spaced apart while maintaining a certain installation gap. The highest surface of the second conveyor belt 53 is coplanar with the highest surface of the first conveyor belt 52. In this way, the friction between the second conveyor belt 53 and the first conveyor belt 52 can drive the fiber pad with a certain weight into the elastic cloth 3. Both conveyor belt 1 52 and conveyor belt 2 53 are driven by independent drive units. Since both conveyor belt 1 52 and conveyor belt 2 53 are commercially available conveyor belts, their specific structures and drive principles will not be described in detail.

[0045] Preferably, the highest surfaces of conveyor belt 52 and conveyor belt 53 are not higher than the worktable of the CNC laser cutting machine.

[0046] Considering the stability of the fiber pad conveyed by the conveying component 5, a certain non-processing area needs to be reserved on the side of the fiber pad that is clamped during cutting.

[0047] In summary, the operating logic of this device is as follows: The fiber pad rests on the worktable of the CNC laser processing machine. The laser cutting head moves above the worktable and cuts out the specified pad shape on the fiber pad. At this time, due to the thickness of the limiting pad itself, without external interference or only by gravity, the cut pad cannot fall off the fiber pad waste. Therefore, the conveying part and conveying component 5 of the CNC laser processing machine are turned on and run at the same speed to send the limiting pad with cutting marks into the frame structure 1. As the conveying component 5 works, when the fiber pad has completely moved between the separation component 2 and the elastic cloth 3, the user uses a G-clamp to clamp the side of the fiber pad to the arrangement plate 11 or the support shell 51, turns on the motor 41, and the piercing rod 23 moves down under the drive of the reciprocating component 4 to pierce the pad off the fiber pad waste. The pad falls onto the elastic cloth 3. Then the G-clamp is released, the conveying component 5 is turned on, or manual labor can be used to remove the waste and pad in batches.

[0048] When removing the pad, a scraper with a handle can be used to scrape the pad off the elastic cloth 3.

[0049] The advantages of the above design are: 1. The introduction of separation component 2 and G-type clamp solves the key problem of the inability to automatically unload the pad after laser cutting, and realizes reliable separation of the pad.

[0050] 2. Using separation component 2 for mechanical separation, the operator only needs to perform clamping and removal operations in a safe position, which significantly reduces the risk of burns and cuts to the operator, while also reducing the possibility of pad deformation, tearing or edge damage due to improper manual operation, thus improving the yield.

[0051] 3. The CNC laser machine tool can work synchronously on the worktable and the separation component 2, realizing parallel cutting and separation. This greatly shortens the time from the completion of cutting to the removal of a single pad, improving the overall production cycle and efficiency.

[0052] 4. Clamping components, such as the G-clamp, effectively prevent the fiber pad from moving or shifting during the puncturing process. The vertically downward-pressing puncture rod 23 can precisely apply pressure to the cutting line, ensuring that the pad is completely and accurately separated from the waste along the predetermined contour, maintaining the accuracy of its shape and size.

[0053] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
