Description

Technical Field

[0001] The utility model belongs to the technical field of metal magnetic powder core production equipment and relates to a metal magnetic powder core production sintering device. Background Art

[0002] Every new material possesses unique and superior properties. In the field of magnetic materials, from metal magnets to ferrite magnets, to amorphous microcrystalline magnets, and finally to metal powder cores, there has been continuous development and progress, with performance constantly improving. Metal powder cores retain the excellent properties of both metal magnets and ferrite magnets while minimizing some of their shortcomings. Among the four major categories of soft magnetic materials, they offer the best overall performance.

[0003] Metal magnetic powder cores vary in shape and are generally formed by pressing powdered raw materials through a mold. The pressed metal magnetic powder cores are then sintered to maintain their shape and stability. The sintering step takes a long time, and a large number of metal magnetic powder cores need to be sintered at one time. The operator needs to place the pressed metal magnetic powder cores and the carbon disk that supports the metal magnetic powder cores into a sintering box together, and take them out after the sintering wall is cooled. The material collection and discharge takes a long time, which reduces the sintering efficiency.

[0004] Based on this, we designed a sintering device for producing metal magnetic powder cores. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems in the existing technology and propose a sintering device for producing metal magnetic powder cores. The technical problem to be solved by this device is: how to load the next batch of products while sintering and improve the sintering efficiency of metal magnetic powder cores.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A sintering device for producing metal magnetic powder cores, comprising a sintering box, wherein both sides of the sintering box are provided with channel openings, an inner sealing plate is provided on the inner side of the sintering box, and a first outer sealing plate and a second outer sealing plate are provided on the outer sides of the two channel openings, respectively; multi-layer stacked storage racks are provided between the inner sealing plate and the first outer sealing plate, and between the inner sealing plate and the second outer sealing plate; a first inclined surface is provided on the inner edge of the channel opening, and second inclined surfaces matching the first inclined surface are provided on both sides of the inner sealing plate; a guide mechanism and a drive mechanism for pushing the first outer sealing plate and the second outer sealing plate to move are provided at the bottom of the sintering box.

[0008] The storage rack includes several support rods, and one end of the support rod is fixed to the inner sealing plate, the other end of some of the support rods is fixed to the first outer sealing plate, and the other end of another part of the support rods is fixed to the second outer sealing plate. Several angle steels are fixed on the support rods, and the angle steels are arranged at an angle, and a barrier rod is fixed to the bottom of the angle steels.

[0009] With the above structure, the operator can place the carbon plate between the two angle steels at the higher end of the angle steel. The carbon plate will slide along the angle steel to the bottom and contact the barrier rod. Similarly, the carbon plate can be removed from the lower end. The operator does not need to place or take out materials in the middle of the storage rack, which makes the operation more convenient.

[0010] The guide mechanism includes two first vertical rods fixed under the first outer sealing plate and two second vertical rods fixed under the second outer sealing plate, and a guide rod is fixed between the first vertical rods and the second vertical rods at corresponding positions. Two fixed sleeves are fixed at the bottom of the sintering box, and the guide rods are slidably arranged in the fixed sleeves at corresponding positions.

[0011] With the above structure, the two guide rods can only slide in the corresponding fixing sleeves, so that the first outer sealing plate, the second outer sealing plate and the inner sealing plate can only move along the direction of the guide rods, preventing them from shaking and improving the stability of the device during operation.

[0012] Vertical rods are fixed to the bottoms of the first vertical rod and the second vertical rod, and rollers are provided below the vertical rods.

[0013] With the above structure, when in use, the roller can provide support force to the first outer sealing plate and the second outer sealing plate, preventing the guide rod from bending under long-term force, and will not hinder the movement of the first outer sealing plate and the second outer sealing plate, further improving the operating stability of the device.

[0014] The driving mechanism includes a through-type linear screw motor fixed to the bottom of the sintering box, the bottoms of the first outer sealing plate and the second outer sealing plate are fixed with fixed rods, and the two ends of the output screw of the through-type linear screw motor are fixedly connected to the two fixed rods respectively.

[0015] With the above structure, the through-type linear screw motor can drive the first outer sealing plate and the second outer sealing plate to move through the two fixed rods, and then drive the inner sealing plate to move. When the inner sealing plate is in contact with and sealed with the channel opening close to the first outer sealing plate, the second outer sealing plate will seal the other channel opening. At this time, the storage rack between the inner sealing plate and the second outer sealing plate will be located inside the sintering box, and the metal magnetic powder core placed above it can be sintered. At this time, the storage rack between the inner sealing plate and the first outer sealing plate is located outside the sintering box, and can be loaded and unloaded, so that the previous batch of materials can be unloaded and the next batch of materials can be loaded while sintering, saving time and improving sintering efficiency.

[0016] The first outer sealing plate and the second outer sealing plate are both provided with a first thermal insulation strip, and both sides of the sintering box are provided with a first card groove matching the thermal insulation strip; the second thermal insulation strip is provided on the second inclined surface of the inner sealing plate, and the first inclined surface of the sintering box is provided with a second card groove matching the second thermal insulation strip.

[0017] With the above structure, when in use, the first thermal insulation strip and the second thermal insulation strip can improve the sealing and thermal insulation effect of the sintering box and improve the sintering effect.

[0018] Reinforcement rods are fixed on the first outer sealing plate and the second outer sealing plate, and the other ends of the reinforcement rods are fixed to the inner sealing plate.

[0019] With the above structure, the reinforcing rod can improve the connection stability between the first outer sealing plate, the second outer sealing plate and the inner sealing plate, thereby improving the stability of the device.

[0020] Compared with the existing technology, this metal magnetic powder core production sintering device has the following advantages:

[0021] 1. Through the sintering box, inner sealing plate, first outer sealing plate, second outer sealing plate and storage rack, the metal magnetic powder core can be placed on the storage rack on one side of the inner sealing plate, and then moved to the sintering box for sintering. At this time, the storage rack on the other side can be loaded and unloaded, thereby saving loading and unloading time and improving sintering efficiency.

[0022] 2. Through the storage rack, the operator can place or remove the carbon plate at one end of the angle steel. The carbon plate will slide along the angle steel to the bottom and contact the stop bar. The operator does not need to place or remove the material in the middle of the storage rack, which makes the operation more convenient.

[0023] 3. Through the guide mechanism and the driving mechanism, the storage rack, the inner sealing plate, the first outer sealing plate and the second outer sealing plate can be stably driven to move, thereby improving the stability of the device operation. In addition, the roller can also provide support for the first outer sealing plate and the second outer sealing plate to prevent the device from being deformed by force and improve the load-bearing capacity of the device.
