Medical nuclear magnetic resonance equipment head processing method

Abstract

The invention discloses a medical nuclear magnetic resonance equipment head processing method, characterized by comprising the processing steps of: firstly, performing positive punching on a stainless steel slab by a head upper mold to form an R part on the outer edge of the stainless steel slab to form a head crude product; punching a hole in the center of the head crude product after positive punching; then disassembling and reversely placing the head upper mold, and putting the head crude product after punching the hole on the reversely placed head upper mold; performing center punching on the head crude product by matching the center punch head with the punched hole in the center of the head upper mold; and trimming the outer edge and the center hole edge of the head crude product to obtain the head product. The processing method disclosed by the invention has high production efficiency, is suitable for mass production, improves the efficiency by 50% compared with the prior art, and causes the head to have stable position, high precision, high concentricity of products and flat bottom surface in production, and the produced head has long service life.

Description

technical field [0001] The invention relates to a method for processing a head, in particular to a method for processing a head applied to medical nuclear magnetic resonance equipment. Background technique [0002] At present, the head of medical nuclear magnetic resonance equipment is generally made of the outer R part by spinning. Since the ball mill is used for spinning, and the material of the ball mill is cast iron, there is iron ion pollution in the R part, which will affect the medical nuclear magnetic resonance. Use of resonance equipment. Moreover, the flatness of the bottom of the head produced by the spinning method cannot be guaranteed, and the concentricity of the central hole cannot be guaranteed, and there will be deviations during installation, which will affect the service life of the nuclear magnetic resonance equipment. The nuclear magnetic resonance equipment has higher requirements on the service life, and the general service life is more than ten years...

Problems solved by technology

[0002] At present, the head of medical nuclear magnetic resonance equipment is generally made of the outer R part by spinning. Since the ball mill is used for spinning, and the material of the ball mill is cast iron, there is iron ion pollution in the R part, which will affect the medical nuclear magnetic resonance. Use of resonance equipment

Moreover, the flatness of the bottom of the head produced by spinning cannot be guaranteed, and the concentricity of the central hole cannot be guaranteed. There will be deviations during installation, which will affect the service life of the nuclear magnetic resonance equipment.

The nuclear magnetic resonance equipment has higher requirements on the service life, and the general service life is more than ten years, and the head is not replaced during this period.

In summary, the heads produced by the existing processing methods cannot well meet the requirements of medical nuclear magnetic resonance equipment.
