Description

Technical Field

[0001] The utility model relates to the technical field of blade production auxiliary equipment, in particular to a blade sintering boat. Background Art

[0002] For carbide cutting and grooving knives, since they are mostly slender products with a high center of gravity and a bottom support pin, they are very likely to tip over during placement, transportation, and sintering, resulting in quality defects such as gaps in the blades. Therefore, a special boat is needed to prevent the cutting and grooving knives from tipping over.

[0003] The commonly used boat at present is a monolithic graphite plate processed with elongated grooves, in which the cutting and grooving knife is placed, and the opposite side walls of the elongated groove are relied on to prevent the cutting and grooving knife from tipping over. However, this monolithic boat has the disadvantage of high processing cost, and because the inner wall of the elongated groove needs to be sprayed with paint before use, the coating on the inner wall of the groove needs to be removed after use, which is extremely difficult to remove. After long-term use, the elongated groove is prone to paint accumulation, so that the accumulated paint damages the blade.

[0004] Therefore, there is an urgent need for a blade sintering boat to solve the above technical problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0032] like Figures 1 to 3As shown, an embodiment of the utility model provides a blade sintering boat, including a layered slot plate 1, a supporting plate 2 and a positioning member 3, wherein the layered slot plate 1 is provided with a plurality of positioning grooves 11 spaced apart along a first horizontal direction, the positioning grooves 11 are long strip grooves extending along a second horizontal direction, the positioning grooves 11 are arranged to pass through the layered slot plate 1 in a vertical direction, and the first horizontal direction, the second horizontal direction and the vertical direction are perpendicular to each other; the supporting plate 2 is located below the layered slot plate 1 and is supported by the supporting plate 2; the layered slot plate 1 is provided with at least two first positioning holes 12 spaced apart along its circumference, the supporting plate 2 is provided with a second positioning hole 21 corresponding to the first positioning hole 12 one by one, and the positioning member 3 is inserted into the second positioning hole 21 after passing through the first positioning hole 12.

[0033] The blade sintering boat is divided into two relatively simple and low-cost parts. The support plate 2 is used to support the layered slot plate 1, and the layered slot plate 1 and the support plate 2 are connected by the positioning member 3 to prevent the layered slot plate 1 from sliding horizontally relative to the support plate 2. The layered slot plate 1 and the support plate 2 can be disassembled and assembled by simply plugging and unplugging the positioning member 3. The disassembly and assembly are simple and quick. Moreover, the inner wall of the positioning groove 11 and the upper surface of the support plate 2 can be sprayed with paint at the same time, and then the layered slot plate 1 and the support plate 2 are connected by the positioning member 3, and the spraying efficiency is high. After the layered slot plate 1 and the support plate 2 are disassembled, the coating on the inner wall of the positioning groove 11 can be removed. Since the positioning groove 11 is a through hole, the coating on the inner wall of the positioning groove 11 is easy to clean. In addition, when any one of the layered slot plate 1 and the support plate 2 is damaged, it can be replaced separately without replacing the whole, which can reduce the sintering cost.

[0034] In some embodiments, Figure 2 As shown, the positioning member 3 includes a positioning portion 31 and a limiting portion 32, one end of the positioning portion 31 is connected to the limiting portion 32, the positioning portion 31 passes through the first positioning hole 12 and then passes through the second positioning hole 21 and transitionally matches with the second positioning hole 21, and the limiting portion 32 abuts against the upper surface of the layered slot plate 1. While the positioning portion 31 is used to prevent the layered slot plate 1 and the supporting plate 2 from relative sliding, the limiting portion 32 can also further limit the relative sliding of the layered slot plate 1 and the supporting plate 2, thereby improving the connection stability between the layered slot plate 1 and the supporting plate 2.

[0035] Exemplarily, the positioning portion 31 and the limiting portion 32 are both cylindrical structures, and the processing cost is low. It should be noted that the positioning portion 31 and the limiting portion 32 can also adopt other shapes, such as both using rectangular rods, or one using a rectangular rod and the other using a cylindrical structure, etc., which will not be illustrated one by one here.

[0036] In some embodiments, Figure 2As shown, the layered slot plate 1 is a rectangular plate, and four positioning members 3 are provided, and the four positioning members 3 are distributed at the four corners of the rectangular plate. Such a configuration will not affect the placement of the slot cutter, and can also improve the connection stability between the layered slot plate 1 and the supporting plate 2. Correspondingly, the supporting plate 2 is also a rectangular plate.

[0037] In some embodiments, Figure 3 As shown, the positioning groove 11 has two supporting inner walls 111 arranged opposite to each other along the first horizontal direction, and the two supporting inner walls 111 are inclined relative to the vertical direction and in opposite directions; along the direction from the supporting flat plate 2 to the layered groove plate 1, the interval between the two supporting inner walls 111 along the first horizontal direction gradually increases.

[0038] With such arrangement, the two supporting inner walls 111 can face upward, so that the paint sprayed on the supporting inner wall 111 can easily adhere to the supporting inner wall 111, thereby alleviating the problem of uneven spraying caused by paint loss. In addition, after the layered slot plate 1 is placed on the supporting flat plate 2, the bottom opening of the positioning slot 11 is closed by the supporting flat plate 2. After the blade is placed in the positioning slot 11, the upper surface of the supporting flat plate 2 between the two supporting inner walls 111 of the positioning slot 11 is used to support the blade. The contact area between the blade and the supporting flat plate 2 is large, which can avoid line contact between the blade and the supporting flat plate 2, thereby protecting the blade; and the blade has good stability after being placed in the positioning slot 11.

[0039] In some embodiments, Figure 3 As shown, the two supporting inner walls 111 are symmetrically arranged about a preset plane, and the preset plane is perpendicular to the first horizontal direction. Such an arrangement can reduce the requirements on the placement direction of the blade.

[0040] In some embodiments, Figure 3 As shown, the angle between the two supporting inner walls 111 is α, and α is 12°-16°. Through experiments with different angles α, it is found that the larger the angle α, the more significant the effect of alleviating paint loss. Correspondingly, after sintering, the paint on the inner wall of the positioning groove 11 and the supporting plate 2 is easier to clean, that is, the lower the cleaning difficulty coefficient; but the probability of the blade tipping over against the supporting inner wall 111 after sintering is greater, that is, the greater the blade tipping rate. In other words, the blade inclination rate and the cleaning difficulty coefficient are contradictory. Figure 4 The curve shown shows that when the angle α is in the range of 12°-16°, not only is the effect of alleviating paint loss significant, but the blade can also be kept as upright as possible, and the blade can be prevented from being tilted so that the blade is slightly bent under its own weight. In addition, during the transportation of the blade, the blade is supported by two supporting inner walls 111, which can effectively prevent the blade from tilting.

[0041] It should be noted that the α sizes of different positioning grooves 11 on the same layered groove plate 1 can be set according to needs, such as setting the α corresponding to multiple positioning grooves 11 to be equal, and the α corresponding to at least one positioning groove 11 can be different from the α corresponding to other positioning grooves 11 to meet the placement requirements of different blades.

[0042] In some embodiments, Figure 3 As shown, the supporting inner wall 111 and the upper surface of the layered slot plate 1 are smoothly connected by a round chamfer 112, so that sharp edges can be avoided at the connection position between the supporting inner wall 111 and the upper surface of the layered slot plate 1, thereby protecting the blade.

[0043] In addition, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
