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.

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0019] The present invention first uses the upper die 1 of the head (such as figure 1 , 2 As shown) positive punching is performed on the stainless steel material plate, so that the outer edge of the stainless steel material plate forms an R position to form a rough product of the head; then the center of the rough product of the head after positive punching is opened; after that, the upper mold of the head is disassembled and reversed placed in the opposite direction, and place the rough head product after the above hole is placed on the reversely placed upper mold of the head; through the center stamping head and the punching hole 2 in the center of the upper mold of the head, the rough product of the head is punched centrally, That is, recoil to form a central hole; then trim the outer edge of the rough head and the edge of the central hole to get the hea...

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...
