Description

Technical Field

[0001] The utility model relates to the technical field of opening holes in single crystal furnace graphite soft felt, in particular to a soft material hole opener and a single crystal furnace graphite soft felt processing device. Background Art

[0002] In the single crystal growth industry, maintaining thermal insulation within the single crystal furnace is crucial. This thermal insulation system typically includes components such as heat shields, insulating graphite felt, and a draft tube. The insulating graphite felt and the draft tube require specialized attachments. However, in practice, creating holes in the graphite felt often requires the use of simple tools, such as sickles or paper cutters. These tools have numerous shortcomings, leading to numerous problems.

[0003] Disadvantages:

[0004] 1. The hole sizes are different and the felt holes are misaligned

[0005] When using non-professional punching tools (such as sickles or paper cutters) to punch holes, the inherent characteristics of the tools make it difficult to maintain consistent hole size, resulting in uneven hole diameters. Furthermore, the operation may cause misalignment of the felt holes, affecting the accuracy and reliability of subsequent assembly.

[0006] 2. The graphite felt structure is destroyed, resulting in non-standard thermal field assembly

[0007] Non-specialized tools often cause unnecessary damage to graphite felt during hole drilling. For example, tools like sickles or paper cutters can cause tearing and uneven cutting of the graphite felt, leading to damage to the overall structure. This not only shortens the lifespan of the graphite felt but can also lead to substandard thermal field assembly, further compromising the quality of single crystal growth.

[0008] 3. The opening is too large, which makes the aperture difficult to adjust and the structure damaged, which destroys the thermal insulation of the graphite felt and reduces the usable period.

[0009] When using non-specialized tools to create holes, the difficulty in operation and controlling the hole location and size can easily lead to excessively large holes. Excessively large holes directly reduce the thermal insulation performance of the graphite felt, as larger holes allow more heat to escape through these pores. Furthermore, excessively large holes can damage the overall structure of the graphite felt, reducing its insulation effectiveness, shortening its useful life, and increasing production costs.

[0010] In summary, the non-specialized hole-making tools used in existing technologies lead to problems such as inconsistent pore sizes, structural damage, and reduced thermal insulation performance in the graphite felt. These problems seriously affect the quality and efficiency of the thermal field assembly during single crystal growth. Therefore, the development of a specialized hole-making tool is of great significance to improving the technical level of the single crystal growth industry. Utility Model Content

[0043] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0044] Example 1

[0045] Reference Figure 1 , this embodiment provides a soft material hole opener, comprising:

[0046] A cylinder 1, wherein the bottom end of the cylinder 1 is an open structure, and a cover 3 is provided on the top end of the cylinder 1, and the cover 3 is provided with a perforation along the central axis of the cylinder 1;

[0047] The cutter head 5 is provided at the bottom of the cylinder 1. The cutter head 5 is a cylindrical structure, and a blade structure 501 is provided at the bottom of the cutter head 5. The blade structure 501 is a circular blade, or the blade structure 501 includes a plurality of toothed blades, and the plurality of toothed blades are evenly arranged around the central axis of the cylinder 1. Due to the design of the blade structure 501, when it presses down and rotates on the soft material, it can cut or cut a circular hole in the soft material.

[0048] a lifting rod 4, the lifting rod 4 being passed through the through hole;

[0049] The radial dimension of the inner ring of the cutter head 5 is no greater than that of the inner ring of the barrel 1. When drilling a hole in a soft material, using graphite felt as an example, the graphite felt is laid flat on a work surface, and one or more positioning points are pre-marked on the graphite felt (the positioning points are used to determine the location of the hole to be drilled). The barrel 1 is held by hand and the hole opener is positioned directly above the positioning points. The hole opener is then pressed down and twisted, and the blade structure 501 is used to cut a circular hole in the soft material. The cut material then automatically enters the inner cavity of the cutter head 5 and is automatically stored. According to the above method, multiple holes can be drilled in sequence according to the actual hole drilling needs and the positions of the positioning points. The material cut by each hole drilling will automatically enter the inner cavity of the cutter head 5 for storage. When the inner cavity of the cutter head 5 is full, the accumulated material will continue to be squeezed upward and enter the inner cavity of the cylinder 1. Since the radial size of the inner ring of the cutter head 5 is not larger than the radial size of the inner ring of the cylinder 1, when entering the inner cavity of the cylinder 1 from the inner cavity of the cutter head 5, the inner ring structure of the cylinder 1 will not form a barrier to the entering material.

[0050] Please note: soft materials, such as graphite felt and other soft felt materials, cloth, rubber pads, paper materials, etc.

[0051] In order to facilitate the entry of the cut material from the inner cavity of the cutter head 5 into the inner cavity of the barrel 1, the barrel 1 and the cutter head 5 are both cylindrical structures with the same inner diameter, and the connection between the inner wall of the barrel 1 and the inner wall of the cutter head 5 is a smooth transition. In this way, when the cut material enters the inner cavity of the barrel 1 from the inner cavity of the cutter head 5, it also has a smooth transition without obstruction. When a large amount of cut material accumulates in the barrel 1 and the cutter head 5, the lifting rod 4 can be pressed up and down to push the cut material out of the bottom opening of the hole opener into a waste recycling box or waste recycling bin, where the waste can be collected and recycled. The smooth transition between the inner wall of the barrel 1 and the inner wall of the cutter head 5 also facilitates the downward push of the material without resistance.

[0052] In this embodiment, a screwing handle 8 is provided on the cylinder 1 or the cover 3. The advantage of providing the screwing handle 8 is that it is convenient to manually screw the entire hole opener for cutting.

[0053] In this embodiment, a push block 6 is provided at the bottom of the lifting rod 4, and a lifting head 2 is provided at the top of the lifting rod 4. The lifting head 2 is provided to facilitate lifting or pressing the lifting rod 4 upwards, and the push block 6 is provided to increase the contact area between the lifting rod 4, the cutter head 5, and the waste accumulated in the barrel 1, so as to facilitate pushing out the accumulated waste for recycling. The lifting head 2 and the push block 6 also have a function: when the lifting rod 4 is lifted, the cover 3 can limit the lifting block to prevent the lifting rod 4 from rising out of the barrel 1; when the lifting rod 4 is pressed downwards, the cover 3 can block the lifting block and limit it to prevent the lifting rod 4 from falling into the barrel 1.

[0054] In this embodiment, the push block 6 is fitted with a gap between the inner wall of the cylinder 1. When the push-pull rod is lifted or pressed down, there is a gap between the push block 6 and the cylinder 1, so there is no friction between them, which facilitates the lifting or pressing of the lifting rod 4.

[0055] In this embodiment, the cover 3 and the cylinder 1 are detachably connected. An assembly cylinder 7 is provided at the bottom of the cover 3. The assembly cylinder 7 is a cylindrical structure. The assembly cylinder 7 and the upper part of the cylinder 1 are assembled in the following ways:

[0056] The first type: the outer diameter of the assembly cylinder 7 is not larger than the inner diameter of the cylinder 1, and the assembly cylinder 7 can be inserted into the cylinder 1 to realize the shaft hole assembly;

[0057] The second type: the outer diameter of the cylinder 1 is not larger than the inner diameter of the assembly cylinder 7, and the cylinder 1 can be inserted into the assembly cylinder 7 to achieve shaft hole assembly;

[0058] The third type: the assembly cylinder 7 and the cylinder body 1 are connected by threads, that is, an internal thread is set inside the assembly cylinder 7 and an external thread is set outside the cylinder body 1, or an external thread is set outside the assembly cylinder 7 and an internal thread is set inside the cylinder body 1, thereby realizing threaded connection therebetween.

[0059] The preferred implementation method in this embodiment is: the assembly cylinder 7 and the cover 3 are an integrally formed structure, the central axis of the cover 3, the central axis of the assembly cylinder 7 and the central axis of the cylinder body 1 are arranged collinearly, and the cylinder body 1 and the assembly cylinder 7 are connected by threads.

[0060] In this embodiment, the lifting rod 4 is matched with the perforation gap, and there is a small gap between the lifting rod 4 and the perforation, which facilitates the lifting or pressing down of the lifting rod 4, and can also limit the axial position of the lifting rod 4 when it is axially extended or retracted to prevent the lifting rod 4 from being offset or stuck.

[0061] The following are the specific steps for using the hole opener:

[0062] 1. Preparation

[0063] Prepare the workbench: Choose a smooth work surface to ensure stability during operation.

[0064] Prepare materials: Prepare the soft felt material (such as graphite felt) that needs to be opened and place it on the workbench.

[0065] Determine the hole location: Mark the location where the hole needs to be made on the soft material as a positioning point.

[0066] 2. Assemble the hole opener

[0067] Check each component: Make sure all components (barrel 1, lifting head 2, cover 3, lifting rod 4, blade 5) are intact.

[0068] Assemble barrel 1: Install cutter head 5 onto barrel 1, ensuring a tight connection. If using a threaded connection, screw cutter head 5 onto barrel 1 until secure. If using an L-shaped snap-on connection, insert cutter head 5 into the corresponding slot on barrel 1. If pre-welded, the connection is already secured and this step can be omitted.

[0069] Install the lifting rod 4: insert the lifting rod 4 and the push block 6 into the cylinder 1 from the top of the cylinder 1.

[0070] Install the cover 3: First, pass the lifting rod 4 through the perforation on the cover 3, and then tighten the cover 3 to the top of the cylinder 1. The lifting rod 4 fits into the clearance of the perforation to prevent the lifting rod 4 from deflecting or getting stuck during operation.

[0071] Install the lifting head 2: The lifting head 2 is connected to the top of the lifting rod 4 through threads or assembled through the shaft hole.

[0072] 3. Start drilling operation

[0073] Alignment: Align the cutter head 5 of the cylinder 1 with the position where a hole needs to be made on the soft material, that is, align the cutter head 5 with the positioning point marked on the soft material, and ensure that the cutter head 5 is perpendicular to the surface of the material.

[0074] Manually press down the lifting rod 4: Hold the lifting rod 4 by hand and gently apply downward force to make the blade structure 501 gradually cut into the material.

[0075] Rotary Cutting: Continue to apply downward force while rotating cylinder 1, allowing blade 5 to evenly cut the material. During this process, blade 5 and the inner cavity of cylinder 1 automatically collect the scraps produced during the hole cutting process. Repeat this action until the desired hole is completed.

[0076] Note: During the hole-making operation, multiple layers of soft materials can be stacked in this manner. It is only necessary to mark the positioning points on the top layer of soft material, so that multiple layers of soft materials can be cut or trimmed at the same time.

[0077] 4. Cleaning and finishing

[0078] Pushing out scraps: After the hole is opened, press down the lifting rod 4 so that the scraps or waste in the cylinder 1 are pushed out from the bottom opening to the waste recovery box.

[0079] Disassembly parts: When the hole opener is not in use, the parts can be disassembled one by one for cleaning and maintenance.

[0080] Cleaning and maintenance: Wipe all parts with a clean cloth to ensure no residue. If necessary, you can wash with water, but make sure the parts are completely dry before storing.

[0081] Precautions

[0082] Safe operation: Pay attention to hand safety during operation to avoid your fingers being cut by the blade 5.

[0083] Apply force evenly: Apply force evenly to avoid excessive force at one time, which may cause damage to the cutter head 5 or material breakage.

[0084] Regular inspection: Check each component regularly for wear or damage. If any abnormality is found, replace it promptly.

When it is necessary to open a hole in a soft material (such as single crystal furnace graphite soft felt), it is only necessary to design the corresponding size of the cutter head 5 according to the required hole size. When in use, align the blade structure 501 with the positioning point for opening the hole in the soft material, and then press down the cylinder 1 and rotate it, and a circular hole will be cut out by the circular blade. Through this hole opener, holes can be opened in graphite soft felt, which improves the consistency of the hole opening, is not easy to be misaligned, is efficient and time-saving, and is not easy to damage the structure.
