Embodiment 1

[0022] see Figure 1-4 , Rare earth magnetic powder automatic forming hydraulic press, composed of feeding system (9), forming pressing system (2), retrieving system (13) and electrical control system (12), feeding and feeding system (9), forming pressing system The system (2) and the reclaiming system (13) are connected to each other in the shape of a character. The shell (5) is sealed with transparent material organic glass, and the interior is connected to each other. An oxygen content detector is installed and filled with an inert protective gas (such as argon gas) etc.), the completely closed system controls the inert gas environment so that the rare earth magnetic powder will not be oxidized.

[0023] Feeding system (9) includes casing (5), feeding shoe (3), telescopic tube (7), hopper (8), weighing device (10), feeder drive cylinder (11) and hydraulic and electrical The control assembly is equipped with a hopper (8) at the top of the feeding system (9), the hopper (8) ...

Abstract

The invention relates to an automatic forming oil-hydraulic press for rare earth magnetic powder, and belongs to the technical field of high-quality rare earth permanent magnet mechatronic processing equipment. The automatic forming oil-hydraulic press for the rare earth magnetic powder consists of a feeding system, a forming and pressing system, a material taking system and an electrical control system, wherein body frames of the feeding system, the forming and pressing system and the material taking system are connected with each other in the shape of Chinese character 'pin'; a shell of the automatic forming oil-hydraulic press is sealed by transparent organic glass materials; and the inside of the automatic forming oil-hydraulic press is mutually communicated and provided with an oxygen content detector, so that the processing operation process of the rare earth magnetic powder can be performed in a completely hermetic inert protective gas environment. The automatic forming oil-hydraulic press has the advantages of automatic powder supply of the feeding system, a magnetic (field) oriental coil in a die component of the forming and pressing system, automatic die lubrication, leftover removal and a completely automatic PLC control system with a low oxygen concentration, and guarantees uniaxial orientation of the height of a magnetic axis of the rare earth magnetic powder and full automation, high accuracy, high reliability and high product quality in the whole pressing production process.

Description

technical field [0001] The invention relates to a rare earth magnetic powder automatic molding hydraulic press, which belongs to the technical field of high-quality rare earth permanent magnet electromechanical instrument integrated processing equipment. Background technique [0002] At present, the traditional rare earth magnetic powder requires two processes without pressing. The first step is to use a simple hydraulic program to press, and requires multiple people to operate. Since the effect of the first hydraulic process is poor, in order to produce anti-fracture performance High rare earth permanent magnets often need to be subjected to a second step of isostatic pressing, and some additional processing steps need to be added before and after the second step is completed, which is inefficient and costly; especially rare earth can not be completed Some restrictions on the characteristics of magnetic powder raw materials, one is the requirements of oxygen-containing subs...
