A Radiation Oriented Ring Forming Equipment

Abstract

The invention relates to a radiation orientation forming equipment, which includes a main cylinder, an upper beam, an upper slider, a female template, a central cylinder, a top cylinder, a workbench and a support. The upper beam, upper slider, female template, and workbench The upper beam is connected and fixed with the workbench through the guide pillars at the four corners, the upper slider and the four corners of the female formwork are slidably matched with the guide pillars, and the bottom of the workbench is supported by the support; the upper slide The upper punch, the upper punch rotation assembly and the upper punch mounting seat are installed on the block, and the upper slider is driven by the master cylinder installed on the upper beam to move vertically along the axis of the guide column; the female template is installed with a female mold , lower punch, mandrel, radiation orientation electromagnet assembly and female mold rotation assembly; the top cylinder is used to drive the female template to move vertically along the axis of the guide post, and the central cylinder is used to drive the mandrel Make it move vertically along the axis of the guide post, and the mandrel is connected with the piston rod of the central cylinder. The invention has the advantages that the equipment has small volume and simple structure, and improves the magnetic performance and quality of the pressed magnet.

Description

technical field [0001] The present invention relates to a hydraulic press, in particular to a radiation oriented ring forming device. Background technique [0002] With the development and maturity of powder metallurgy technology, more and more materials are produced by powder metallurgy technology. It first presses the powder into a cake through a powder molding machine, and then sinters to make the final product. [0003] Our company's utility model patent with the patent number CN 103286980 A discloses a molding device for a radial orientation forming hydraulic press, which is mainly fixedly connected with the upper inner magnet and the upper die punch, and the inner ring of the upper die punch is fixedly connected with the inner ring of the upper die punch. Magnetic conductor, the top of the upper inner magnetic conductor is fixedly connected to the upper slider, and the outer ring of the upper inner magnetic conductor is connected with an upper orientation coil. It is...

Problems solved by technology

[0004] The disadvantages of the molding device of the above-mentioned radiation orientation molding hydraulic press are: 1. The magnetic domains of the magnetic powder in the mold cavity are radially arranged by rotating the magnetizer to generate a radiation orientation magnetic field. In this way, the magnetic field intensity of the magnetic powder in the mold cavity Smaller, the magnetic properties of its products are low, and the magnetic field strength of its pressed magnet is 0.4-0.8T; 2. Through the magnetic conductor, the upper and lower orientation coils and the upper and lower magnetic conduction circuits, the magnetic domains of the magnetic powder in the mold cavity are radially arranged, and its structure Complicated and increases the space volume of the device
