Description

Technical Field

[0001] The present application relates to the technical field of tooling structures, and in particular to a tooling for heat treatment of a cutter head. Background Art

[0002] In order to reduce the weight of the cutter disc, aluminum alloy is mostly used in the prior art. However, since aluminum itself is relatively soft and will become even softer after heat treatment, the material of the cutter disc may deform downward due to its own gravity during the heat treatment, affecting the structural accuracy of the cutter disc after the heat treatment. If a tooling structure that is completely in contact with the ground of the cutter disc is used, it is inconvenient to separate the cutter disc from the tooling after the heat treatment. Summary of the invention

[0003] The purpose of the present application is to provide a tooling that can ensure the accuracy of the cutter disc after heat treatment and is easy to disassemble.

[0004] In order to achieve the above purpose, the present application provides a cutter disc heat treatment tool: including a tray, on which a plurality of guide columns are plugged, and the plurality of guide columns are suitable for jointly plugging products, and the end surface of the product facing the tray is the lower end surface, and there are a plurality of products. A partition is provided between the lowest product and the tray, and partitions are also provided between adjacent products, which are suitable for providing support force to the uneven lower end surface of the product to prevent the heat-softened cutter disc material from sinking under its own weight.

[0005] Preferably, the separator includes independent large separator blocks, small separator columns, small separator blocks, large separator columns and special-shaped separator blocks, which are suitable for contacting different parts of the product and independently supporting parts of the cutter disc that are prone to deformation.

[0007] As a preferred embodiment, the large dividing block is suitable for contacting with the flat area of ​​the edge of the cutter disc portion. The large dividing block is a hollow structure and is provided with a first limiting hole passing through the upper and lower end surfaces. The large dividing block is suitable for being inserted into the guide column to form a sliding pair to limit the position of the large dividing block relative to the product.

[0008] As a preferred embodiment, the small dividing column and the small dividing block are suitable for contacting with a smaller flat area on the upper end face or the lower end face of the cutter disc portion, the small dividing column is provided with a second limiting hole passing through the upper and lower end faces, and the outer side face of the small dividing column is also provided with a friction groove; the small dividing block also begins to have a third limiting hole passing through the upper and lower end faces, and the second limiting hole and the third limiting hole are suitable for being inserted into the guide column to facilitate disassembly and assembly operations.

[0009] As a preferred embodiment, the large partition column includes a column body, the upper end of the column body has a disk body, which is suitable for contacting with a larger flat area on the lower end surface of the cutter disc part. The large partition column is provided with a fourth limiting hole extending from the upper end surface of the disk body to the lower end surface of the column body, which is suitable for being inserted into the guide column. There is also a rib plate between the lower end surface of the disk body and the outer side surface of the column body to ensure the structural stability of the large partition column when it is subjected to a large load.

[0010] As a preferred embodiment, the lower end face of the special-shaped dividing block has a clamping plate, which is suitable for fitting with the groove on the upper end face of the cutter disc part. The upper end face of the special-shaped dividing block is provided with a clamping groove, which is suitable for fitting with the reinforcing ribs on the lower end face of the cutter disc part, thereby providing stable support for the raised structure on the lower end face of the product.

[0011] As a preference, the upper end surface of the tray is provided with a plurality of insertion holes suitable for being plugged into the lower end of the guide column. When the tooling is not in use, removing the guide column can effectively save the space occupied by the tooling structure and facilitate transportation.

[0012] As a preference, a plurality of support columns are fixedly connected to the lower end surface of the tray, and the lower ends of the plurality of support columns are in the same horizontal plane for direct contact with the placement surface, so that the tray is suspended at a certain height above the ground.

DETAILED DESCRIPTION

[0030] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0033] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0034] like Figure 1-12 The tooling for heat treatment of the cutter disc shown includes a pallet 1 whose upper and lower end surfaces are both horizontal. The pallet 1 is made of high temperature resistant material. A plurality of guide posts 3 are plugged into the pallet 1, so that the guide posts 3 and the pallet 1 are detachable when separated. A plurality of insertion holes 101 are provided on the upper end surface of the pallet 1 for plugging with the lower ends of the guide posts 3. A plurality of support posts 102 are fixedly connected to the lower end surface of the pallet 1. In this embodiment, the insertion holes 101 pass through the upper and lower surfaces of the pallet 1, and the support posts 102 are located below the insertion holes 101, just blocking the lower ends of the insertion holes 101. The lower ends of the support posts 102 are in the same horizontal plane, and are used to directly contact the ground or the bottom surface of the inner cavity of the heat treatment equipment, so that the lower end surface of the pallet 1 is suspended at a certain height from the ground, which is convenient for the forklift's mechanical arm to reach under the pallet 1 and lift the entire tooling.

[0035] A plurality of guide posts 3 are suitable for jointly inserting products 2, and the end face of the product 2 facing the tray 1 is defined as the lower end face. There are usually a plurality of products 2 that can be placed on the tray 1, and a pressing block 4 made of a high temperature resistant material is also placed on the upper end face of the product 2 located at the top, so that the upper end face of the product 2 located at the top can also be subjected to downward pressure. The pressing block 4 is solid and has a large weight, thereby ensuring that sufficient pressing effect is provided to the top product 2. The pressing block 4 is also inserted into the guide post 3 to prevent the pressing block 4 from shaking relative to the product 2, so that after the product 2 is placed on the tooling, the upper The end also has very good stability. The main part of the product 2 is the blade disc part 201. The upper and lower end surfaces of the blade disc part 201 have various uneven three-dimensional structures for improving the structural strength of the blade disc part 201 itself. For example, the lower end surface of the blade disc part 201 has obviously protruding reinforcing ribs 204, and the blade disc part 201 is provided with a guide hole 203 passing through the upper and lower end surfaces for the guide column 3 to pass through to form a sliding pair; the side of the blade disc part 201 also has an integrated extension part 202, which is not in the same plane as the blade disc part 201, but is also inserted into the guide column 3.

[0036] A partition 5 is provided between the bottom product 2 and the tray 1, and a partition 5 is also provided between adjacent products 2 to prevent the product 2 from directly contacting the tray 1 or other products 2. Without direct contact, they will not stick to each other, which facilitates separation operations after heat treatment. The partition 5 includes independent large partition blocks 510, small partition columns 520, small partition blocks 530, large partition columns 540 and special-shaped partition blocks 550. These independent components are all made of high-temperature resistant materials, such as alloys or ceramics, and are used to contact different parts of the product 2, thereby providing support for the uneven lower end surface of the product 2 and reducing the degree of distortion caused by the product 2's own gravity after being heated.

[0037] Specifically: the large partition block 510 will contact the flat area of ​​the edge of the blade disc part 201 to prevent the edge of the blade disc part 201 from being dented after being softened by heat. Because the large partition block 510 is large in size, it is usually made into a hollow structure to reduce consumables and reduce its own weight, which makes it easier to take, place and configure. The large partition block 510 is provided with a first limiting hole 511 that passes through the upper and lower end surfaces, and there are usually at least two of them, which are used to be inserted into the guide column 3 to form a sliding pair, thereby limiting the horizontal position of the large partition block 510 relative to the product 2; the small partition column 520 and the small partition block 530 are both suitable for contacting the smaller flat area on the upper or lower end surface of the blade disc part 201. The small partition column 520 is cylindrical and can be flexibly configured. The activity will be higher, but it basically only provides vertical force on product 2, and the constraint on product 2 is not high; the small partition block 530 is prism-shaped, usually a quadrangular prism, and must be configured at a specific position on the end face of product 2. It has relatively low flexibility, but can provide additional horizontal constraint to product 2. Therefore, the small partition column 520 and the small partition block 530 are used in conjunction to take into account the requirements of convenience and stability. The small partition column 520 is provided with a second limiting hole 521 that passes through the upper and lower end faces for insertion with the guide column 3. The outer side surface of the small partition column 520 is also provided with a friction groove 522 for increasing the friction of holding the small partition column 520; the small partition block 530 also begins to have a second limiting hole 521 that passes through the upper and lower ends. The third limiting hole 531 on the surface is also used to be inserted into the guide column 3, so as to maintain stability relative to the tray 1 or the product 2. The large partition column 540 includes a cylindrical column 541. The lower end of the column 541 will directly contact the upper end surface of the tray 1 or the product 2 below. The upper end of the column 541 has a coaxial disk 542. The diameter of the disk 542 will be slightly larger and is used to contact the larger flat area of ​​the lower end surface of the cutter disc part 201. Usually, the area of ​​the flat area on the upper end surface of the cutter disc part 201 is slightly larger than the flat area of ​​the lower end surface, so as to prevent the material in the corresponding area from sinking when softening. The large partition column 540 is provided with a fourth limiting hole 543 extending from the upper end surface of the disk 542 to the lower end surface of the column 541, which is used to contact with the larger flat area of ​​the lower end surface of the cutter disc part 201. The guide column 3 is inserted, and a rib 544 is provided between the lower end surface of the disk body 542 and the outer side surface of the column 541, which is used to improve the structural strength of the disk body 542 and prevent the edge of the disk body 542 from bending downward due to pressure; the lower end surface of the special-shaped dividing block 550 has a clamping plate 551, which is used to fit with the groove on the upper end surface of the blade disc part 201, and the upper end surface of the special-shaped dividing block 550 is provided with a clamping groove 552, which just fits with the reinforcing rib 204 on the lower end surface of the blade disc part 201. Since the fitting structure at the upper and lower ends of the special-shaped dividing block 550 is stable enough, there is no need for an additional limiting hole structure to be inserted into the guide column 3. Compared with other dividing parts 5, the movement amplitude of the special-shaped dividing block 550 in the placement and configuration operation is the smallest.

[0038] Working principle: When configuring product 2 on the tooling, pallet 1 is located outside the heat treatment equipment, and all guide posts 3 are inserted above pallet 1. Then, each partition 5 can be configured on pallet 1 by being put on the guide posts 3. The combination of partitions 5 that are in direct contact with pallet 1 may not include special-shaped partition blocks 550. Then, align the guide holes 203 of product 2 with guide posts 3 and slide down until they contact the partitions 5 below. Then, the combination of partitions 5 of the upper layer can be configured upward, and thereafter, the special-shaped partition blocks 550 can be included. Continue to stack products 2 upward until the height of the unmatched part of the upper end of guide posts 3 is slightly greater than the thickness of pressing block 4. Finally, press block 4 is inserted into guide posts 3 to complete the configuration of cutter disc product 2 on the tooling. Then, use a forklift to lift pallet 1 and place it in the heat treatment equipment for heat treatment. Since the parts of product 2 that may sink after being softened by heat are fully supported, no distortion that affects the accuracy of its own structure will occur after the heat treatment.
