Description

Technical Field

[0001] The utility model relates to the technical field of MIM-related accessories, in particular to a sintering fixture for long strip products. Background Art

[0002] Before degreasing and sintering, long structural products need to be placed on a flat sintering support. During transportation, the products are easily displaced due to vibration, causing the products to stick or adhere. In addition, during the sintering shrinkage process, only the plane deformation of the product in contact with the support plate can be guaranteed to be minimal, and the deformation of other surfaces of the product that are not in contact with the support plate cannot be guaranteed. The deformation of the product after sintering is extremely unstable and needs to be divided into different specifications through selection, and then post-processing and shaping to correct the shape and size of the product, which greatly increases the production cost.

[0030] The support base 1 is provided with a plurality of V-shaped grooves 2 for placing long strip products in an array; the groove depth of the V-shaped grooves 2 is 0.5-1.5 mm larger than the outer contour of the long strip product, so as to facilitate the placement of the product;

[0031] The two sides of the V-shaped groove 2 are arranged vertically, and the 90° right angle can better fit the product to the bottom and side of the V-shaped groove 2, guide the product, and reduce the shrinkage deformation of the product;

[0032] The depth of the V-shaped groove 2 is half of the thickness of the support base 1, so that the depth of the V-shaped groove 2 is ensured while ensuring the thickness and hardness of the support base 1;

[0033] A peak gap 3 is provided between the V-shaped grooves 2, so that there is a certain distance between the V-shaped grooves 2, thereby ensuring that the products do not collide with each other and preventing the products from sticking to each other during sintering.

[0034] In order to prevent the products from sticking together due to vibration during sintering, a partition plate 4 is provided in the middle of the support base 1; the partition plate 4 is made of ceramic material; the partition plate 4 is movably arranged in the middle of the support base 1; the movably arranged partition plate 4 can also be installed or removed according to the size and length of the product to better meet the processing requirements.
