Description

Technical Field

[0001] This utility model relates to the field of sintering carrier technology, and in particular to a sintering carrier for thin-walled medical clamp products. Background Technology

[0002] Sintering is a process in which hard compounds of refractory metals and binder metals are used to produce alloy materials through powder metallurgy. During the sintering process of medical clamp products, the thin-walled structure at the clamp opening is subjected to frictional forces, resulting in severe outward deformation during sintering shrinkage, which cannot meet dimensional requirements. Therefore, this invention proposes a sintering carrier for thin-walled medical clamp products. Utility Model Content

[0003] The main objective of this invention is to provide a sintering carrier for thin-walled medical clamp products to solve the problems mentioned in the background art.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a sintering carrier for thin-walled medical jaw products, comprising a base plate, support strips on both sides of the upper surface of the base plate, support blocks connected to the upper surfaces of the two support strips, limiting grooves along the length direction on both the upper and lower surfaces of the support blocks, and multiple jaw products distributed on the support blocks between the two support strips. Each jaw product includes a main body, an upper arm, and a lower arm, the upper arm and the lower arm being distributed on the upper and lower sides of the support block, and columnar bosses on the opposite surfaces of the upper arm and the lower arm. A receiving groove is provided on the base plate below the support block. The base plate, the support strips, and the support blocks are all made of high-temperature resistant ceramic.

[0005] Preferably, the width of the limiting groove is greater than the diameter of the boss, and the depth of the limiting groove is greater than the thickness of the boss.

[0006] Preferably, the distance between the two bosses is less than the thickness of the support block.

[0007] Preferably, multiple support blocks and accommodating grooves are provided along the length direction of the base plate.

[0008] The beneficial effects of this utility model are: the jaw product "straddles" on the support block, the support block is placed flat on the support strip, the support block is used to support the upper arm, the upper arm is attached to the upper surface of the support block under its own weight to prevent deformation, the lower arm is located in the receiving groove, and the bottom plate supports the lower arm to prevent the lower arm from deforming during the sintering process, thereby ensuring product quality.

[0012] The present invention will be further described in detail below with reference to specific embodiments.

[0013] Example: like Figure 2 As shown, this utility model discloses a sintering carrier for thin-walled medical forceps, comprising a base plate 1. Support strips 2 are provided on both sides of the upper surface of the base plate 1. Support blocks 3 are connected to the upper surfaces of the two support strips 2. Limiting grooves 4 are provided on both the upper and lower surfaces of the support blocks 3 along their length. Multiple positioning grooves 4 are distributed on the support blocks 3 between the two support strips 2. Figure 1 The jaw product 5 shown includes a main body 6, an upper arm 7, and a lower arm 8. The upper arm 7 and the lower arm 8 are distributed on the upper and lower sides of the support block 3. Each of the upper arm 7 and the lower arm 8 has a columnar boss 9 on its opposite side. The base plate 1 has a receiving groove 10 located below the support block 3. The base plate 1, the support bar 2, and the support block 3 are all made of high-temperature resistant ceramic. During installation, the support block 3 is removed and placed vertically. From one side of the support block 3, the boss 9 of the jaw product 5 to be sintered is aligned with the limiting groove 4 and pushed in, so that the jaw product 5 "straddles" the support block 3. The support block 3, which contains multiple jaw products 5, is placed flat on the support bar 2. The lower arm 8 of each jaw product 5 has a stepped portion 11 at its lower end face that is higher than the lower end face of the lower arm 8. The lower arm 8 is located in the receiving groove 10, and the stepped portion 11 rests on the upper end face of the base plate 1. The installed carrier is sent into the furnace for sintering. The support block 3 is used to support the upper arm 7. The upper arm 7 adheres to the upper end face of the support block 3 under its own weight to prevent deformation. The lower arm 8 is located in the receiving groove 10, and the base plate 1 supports the lower arm 8 to prevent deformation of the lower arm 8 during sintering, thereby ensuring product quality.

[0014] The width of the limiting groove 4 is greater than the diameter of the boss 9, and the depth of the limiting groove 4 is greater than the thickness of the boss 9, ensuring that the boss 9 can slide along the limiting groove 4 when the jaw product 5 is installed on the support block 3.

[0015] The distance between the two protrusions 9 is less than the thickness of the support block 3.

[0016] Multiple support blocks 3 and accommodating grooves 10 are provided along the length of the base plate 1, which is suitable for mass production needs and improves efficiency.

[0017] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
