Problems solved by technology

However, replacing the material with cemented carbide has the following disadvantages: on the one hand, the material is too hard to process, and the cost of manufacturing molds is much higher than ordinary mold steel
Due to the addition of the isostatic pressing process, not only the prolongation of the process increases the possibility of the magnet being oxidized, but also about 3% of the magnet will be lost in vain due to oil leakage and cannot be recycled
In addition, due to the existence of the isostatic pressing process, the orientation forming and magnet sintering processes of magnet production cannot be connected together, and the integrated automatic production of orientation forming and magnet sintering cannot be realized

Embodiment 1

[0096] will be like Figure 9-10 Shaped as shown Ø3.1×20.1mm 3 The forming device of the cylindrical magnet is put into the press and produced in the atmospheric environment.

[0097] The specific operation steps are as follows:

[0098] S1: At the No. 1 station, the cylinder pushes out the magnet 24 after pressing and molding last time, and the magnet 24 after molding is a cylindrical magnet;

[0099] S2: The part except the baffles on both sides is driven by the mobile mold driving device, that is, the mobile mold 100 to the No. 2 station;

[0100] S3: The cylinder 13 clamps the baffles 15 on both sides to close the mold;

[0101] S4: When the cylinder 13 is clamped, after the mold continues to move forward for a certain distance driven by the mobile mold driving device, the distance between the baffle plate 15 on both sides and the guide plate 2 gradually decreases to a tight sliding fit, and the cylinder 13 is released;

[0102] S5: The mold moves forward to the No. 3 ...

Embodiment 2

[0110] Will Figure 9-10 Forming Ø5.15×20.1mm shown 3 The forming device of the columnar magnet is placed in a sealed press, and nitrogen is filled after repeated vacuuming until the oxygen content is below 100ppm. Other steps follow the forming process of Example 1 to produce the magnet.

[0111] This embodiment is suitable for occasions where automatic molding requires higher density of magnets.

[0112] The magnetic properties and system production efficiency of the magnet formed in this embodiment are shown in Table 1.

Embodiment 3

[0114] Will Figure 11 Forming shown 146 x 80 x 12 mm 3 The forming device of the sheet magnet is placed in a press and produced in an atmospheric environment.

[0115] S1: At the No. 1 station, the cylinder 7 pushes out the magnet 24 after pressing and molding last time, and the magnet 24 after molding is a square piece;

[0116] S2: The linear drive mechanism, such as the cylinder 36, drives the rack 35 installed on the slide rail of the bottom plate 12 to go down, and drives the gear 33 on the rotating shaft 34 to drive the rotating shaft 34 to rotate. The rotating shaft 34 is connected with the bracket 30 fixed on the bottom plate 12 through a self-locking thread pair 37 . At this time, the rotating shaft moves toward the mold for a small distance along the moving direction of the mold, thereby pushing the adapter sleeve 29, the front baffle plate 28, the forming block 25, and the forming block 23 to press the rear baffle plate 1 step by step, thereby forming four U-shap...

Abstract

The invention relates to a magnet automatic forming system and method. The molding system includes a moving mold, a driving device for the moving mold, a base, a slide rail, a left guide plate, a right guide plate, a magnet ejection device at the No. 1 station, and a left and right side stopper at the No. 2 station. Plate and side baffle mold clamping device and mold unloading device, feeding mechanism at No. 3 station, upper pressure head orientation forming device at No. 4 station, moving mold includes base plate, front baffle, rear baffle, The bottom plate is provided with a molding area that matches the orientation molding device of the upper pressure head, the slide rail is fixed on the base, the left guide plate and the right guide plate are fixed on the base, and are respectively located on the left and right sides of the mobile mold. The side extends from the No. 4 station to the No. 2 station; the mobile mold is driven by the mobile mold driving device to slide on the slide rail. The invention can ensure the high-density orientation pressing and non-destructive demoulding of the magnet, and improves the degree of automatic production.

Description

technical field [0001] The invention mainly relates to a magnet automatic forming system, in particular to a magnet automatic forming system and method, a sheet magnet forming mold, and a dismantling device. Background technique [0002] With the wide application of rare earth magnets, the market size and competition are getting bigger and bigger. How to use less rare earths to obtain high-performance magnets, and to obtain magnets with higher production efficiency and stable performance with less manual operation has attracted extensive attention and attempts in the industry. The compression orientation molding from magnetic powder to magnet is an essential key process in magnet production. In traditional production, the disassembly and assembly of the mold, the weighing of magnetic powder, the distribution of powder in the mold before compression molding, and the removal of the magnet after orientation molding are all done manually. Due to manual participation, in this p...
