Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of single crystal silicon production, in particular to a low-cost tooling for a graphite spliced heater. Background Art
[0002] In the production of single crystal silicon, a graphite main heater is required. However, since most of the current mainstream spliced heaters are "plum blossom-shaped" multi-lobe split types composed of four arc heaters spliced together, they are the most difficult to clamp and process. Generally, after a round material is cut into slices by a numerical control wire saw, grooves are opened on a horizontal machining center, and the tooling fixture used needs to be made of two graphite ring materials, and then the workpiece is fixed by a wooden pressing plate. This method has too long manual operation time, wastes a lot of graphite materials, has too high cost, and the inner diameters of the products are different and cannot be universal. A tooling needs to be made for each specification, which wastes even more graphite materials. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a low-cost tooling for a graphite spliced heater. The tooling has a reasonable and compact structure, and the split graphite patches can be reused many times, greatly reducing the graphite material, reducing the tooling production cycle and material waste of redundant products, and can fully improve the utilization rate of the machine tool and improve the processing efficiency.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a low-cost tooling for a graphite spliced heater, the structure of which includes a tooling main body. The tooling main body is a cylindrical ring, and also includes a spliced heater, a graphite bottom patch, a pressing component, a base and a graphite side patch. The base is arranged at the bottom of the tooling main body, and a plurality of arc-shaped graphite bottom patches are arranged on the top of the base. Four arc-shaped graphite side patches are arranged on the upper part of the graphite bottom patch. The four arc-shaped graphite side patches are respectively connected to the side wall of the tooling main body by screws, and the pressing component is arranged on the top of the tooling main body.
[0005] Further, a number of toad clamp installation positions are evenly arranged on the upper part of the outer side wall of the tooling main body, and each toad clamp installation position installs a toad clamp. The fixed end of the toad clamp is arranged on the outer side of the upper part of the graphite side patch.
[0006] Further, the pressing component includes a cross plate, a vertical plate and a bolt. One end of the cross plate is connected to the top end of the vertical plate. A long strip hole is arranged in the middle of the cross plate. One end of the screw of the bolt passes through the long strip hole and extends to the lower part of the cross plate, and the other end of the screw is threadedly connected to a nut.
[0007] Further, a gasket is arranged between the nut and the top wall of the cross plate.
[0008] Further, the four arc-shaped graphite side patches form a ring shape.
[0009] Furthermore, a number of corresponding fixing holes are respectively provided on the tooling main body and the graphite side patch, and the screws are fastened after passing through the fixing holes of the graphite side patch and the tooling main body in sequence.
[0010] Furthermore, both the tooling main body and the base are made of cast iron.
[0011] Advantages of the present utility model:
[0012] The tooling of the present utility model solves the problem that the previous graphite patch was integral, and different graphite patches needed to be replaced for each specification of heating product. However, for the single-piece graphite side patch, it can be ground to a suitable diameter according to different specifications of heaters, and one graphite patch can be reused multiple times, reducing the use of graphite material, greatly saving costs, and preventing waste.
[0013] Since a plurality of pressing components are provided on the upper part of the tooling body, and each single-piece heater can be pressed separately by each pressing component, this tooling is more suitable for fixing the "plum blossom-shaped" multi-piece split heaters, with strong firmness, and can fully improve the utilization rate of the machine tool and the processing efficiency.

[0020] The following is a detailed description of a low-cost tooling for a graphite spliced heater of the present utility model with reference to the attached drawings of the specification.
[0021] As shown in Figures 1 to 4As shown in the figure, a low-cost tooling for a graphite spliced heater proposed by the present utility model includes a tooling main body 1. The tooling main body 1 is a cylindrical ring shape, and a number of fixing holes are evenly arranged on the circumferential side wall of the tooling main body 1. The fixing holes are threaded holes to facilitate the disassembly and assembly of graphite patches. It also includes a spliced heater 4, a graphite bottom patch 5, a pressing component 3, a base 6, and a graphite side patch 8. The base 6 is arranged at the bottom of the tooling main body 1. A number of arc-shaped graphite bottom patches 5 are arranged on the top of the base 6. Four arc-shaped graphite side patches 8 are arranged on the upper part of the graphite bottom patch 5. The four arc-shaped graphite side patches 8 are respectively connected to the side wall of the tooling main body 1 by screws. In the later stage, when processing heaters of different categories and specifications, the original integral graphite can be divided into multiple arc-shaped graphite patches in the form of inlaying graphite patches on the outer shape of the tooling body, which greatly reduces the graphite material and reduces the tooling production cycle and material waste of redundant products. The pressing component is arranged on the top of the tooling main body, which improves the firmness of the tooling use. The tooling main body and the base are both made of cast iron material, which improves the overall strength of the tooling.
[0022] A number of toad clamp installation positions 7 are evenly arranged on the upper part of the outer side wall of the tooling main body 1. Each toad clamp installation position installs a toad clamp 2. The fixed end of the toad clamp 2 is arranged on the outer side of the upper part of the graphite side patch 8. By arranging a number of toad clamps on the upper part of the circumferential side wall of the tooling body, the installation stability of the heater can be improved.
[0023] The pressing component 3 includes a cross plate 31, a vertical plate 32, and a bolt 33. One end of the cross plate 31 is connected to the top end of the vertical plate 32. A long strip hole 34 is arranged in the middle of the cross plate 31. One end of the screw rod of the bolt 33 passes through the long strip hole 34 and extends below the cross plate 31. The other end of the screw rod is threadedly connected to a nut. A gasket 35 is arranged between the nut and the top wall of the cross plate, which improves the firmness of the bolt fastening.
[0024] The four arc-shaped graphite side patches 8 form a ring shape. The single-piece graphite side patch can be polished to a suitable diameter for each graphite patch according to the heaters of different specifications, and one graphite patch can be reused many times.
[0025] The tooling main body 1 and the graphite side patch 8 are respectively provided with a number of corresponding fixing holes. After a number of screws pass through the fixing holes of the graphite side patch and the tooling main body in sequence and are tightened, the fixing of the patch and the tooling body is realized.
[0026] The present utility model changes the tooling body and the base from graphite material to cast iron structure to improve the overall strength of the tooling. Moreover, it screens and analyzes according to the inner diameter specifications of existing products, selects the minimum inner diameter specification, manufactures the outer diameter of the tooling body, and arranges threaded holes on the outer diameter of the tooling body. In the later stage, heaters of different categories and specifications can be processed in the form of fixing four arc-shaped graphite patches on the outer shape of the tooling body. Only one base and one tooling body are needed, and the inner diameter of the product is modified through the patch form to realize the sharing of one tooling, reducing the waste of graphite tooling materials by more than 5 times, realizing rapid die change, and increasing the processing efficiency by 15%.
[0027] As described above, only some principles of the present utility model are illustrated by diagrams. This specification is not intended to limit the present utility model to the specific structures and application scopes shown and described. Therefore, all possible corresponding modifications and equivalents that can be utilized belong to the scope of the patent applied for by the present utility model.
[0028] Except for the technical features described in the specification, the rest of the technical features are known technologies to those skilled in the art.
