Description

Technical Field

[0001] The invention relates to the technical field of manganese-zinc ferrite cores, in particular to a method for sintering a DQS160 product. Background Art

[0002] In the production process of manganese-zinc soft ferrite, the powder is first filled into the mold, the powder is formed into a blank with a certain strength, and the blank is placed in a nitrogen atmosphere protection kiln for sintering. The sintered product is the final product;

[0003] The DQS160 product is a newly developed large product, which is mainly used in light storage and charging, high-power charging technology, intelligent operation and maintenance platform, etc. The product requires appropriate bending in the lateral direction; the original sintering method requires a single-open side bending mold to be pressed, and an ordinary setter is used. A small amount of corundum sand is sprinkled on the ordinary setter. The DQS160 blank is directly placed flat on the corundum sand for single firing. Since the DQS160 blank is relatively large, the blank shrinks inconsistently during sintering. After sintering, the lateral bending size is large and small, resulting in unqualified lateral bending size, causing waste; this method is not only time-consuming and labor-intensive, but also wastes labor, and has an important impact on the quality of the product;

[0004] In view of the above situation, it is necessary to improve the existing DQS160 sintering method so that it can adapt to the current needs for the DQS160 sintering method. Summary of the invention

[0005] To achieve the above object, the technical solution of the present invention is a method for sintering a DQS160 product, comprising the following steps:

[0006] Step 1: Use two zirconium pressing plates to splice together and tilt them towards the middle;

[0007] Step 2: Sprinkle a small amount of yellow zircon sand on the zirconium pressing plate;

[0008] Step 3: Center the DQS160 blank in the depression.

[0009] As a further supplement to the technical solution, the dimensions of the two zirconium pressed plates are 320*160*13 mm.

[0010] As a further supplement to the technical solution, the yellow zircon sand is 80 mesh yellow zircon sand.

[0011] As a further supplement to the technical solution, support fixtures are provided under the two zirconium pressing plates and on both sides.

[0012] As a further supplement to the technical solution, the two zirconium pressed plates are recessed downward at an angle of 15°.

[0013] As a further supplement to the present technical solution, the supporting tooling includes a fixed base plate and a supporting mechanism symmetrically arranged on both sides above the fixed base plate, the supporting mechanism includes a first supporting block arranged on one side above the fixed base plate and a second supporting block arranged on the other side above the fixed base plate, and the first supporting block and the second supporting block are fixedly installed on the fixed base plate.

[0014] As a further supplement to the technical solution, the upper surface of the first support block is at an angle of 15° to the horizontal plane.

[0015] As a further supplement to the technical solution, the upper surface of the second support block forms an angle of 15° with the horizontal plane.

[0016] The beneficial effect is that during sintering, the DQS160 blank will bend downward due to its own weight. The inclination angle of the zirconium pressing plate is set to 15°, so that the side bending of the sintered product meets the product requirements. The product sintered by this method has good dimensional consistency and various performances meet customer requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical solution more clear to those skilled in the art, Figure 1 The technical solution of the present invention is described in detail:

[0020] A method for sintering a DQS160 product comprises the following steps:

[0021] Step 1: Use two zirconium pressing plates to splice together and tilt them towards the middle;

[0022] Step 2: Sprinkle a small amount of yellow zircon sand on the zirconium pressing plate;

[0023] Step 3: Center the DQS160 blank in the depression;

[0024] During operation and sintering, the DQS160 blank will bend downward due to its own weight. We set the inclination angle of the zirconium pressing plate to 15°, so that the side bending of the sintered product meets the product requirements. The product sintered by this method has good dimensional consistency and various performances meet customer requirements.

[0025] Among them, the dimensions of the two pressed zirconium plates are 320*160*13mm.

[0026] Among them, the yellow zircon sand is 80 mesh yellow zircon sand.

[0027] Among them, a supporting tooling 1 is provided under the two zirconium pressing plates and is arranged on the left and right sides.

[0028] Among them, the two pressed zirconium plates are concave downward at an angle of 15°.

[0029] The structure of the supporting tooling will be described in detail below. The supporting tooling 1 includes a fixed base plate 2, and a supporting mechanism 3 symmetrically arranged on both sides above the fixed base plate 2. The supporting mechanism 3 includes a first supporting block 4 arranged on one side above the fixed base plate 2, and a second supporting block 5 arranged on the other side above the fixed base plate 2. The first supporting block 4 and the second supporting block 5 are fixedly installed on the fixed base plate 2; wherein, the upper surface of the first supporting block 4 forms an angle of 15° with the horizontal plane; and the upper surface of the second supporting block 5 forms an angle of 15° with the horizontal plane.
