Method for preparing C-shaped arm

Abstract

It relates to mechanical parts manufacturing and processing. The proposed C arm is made by compressing the mold to make the direct bar like material, bending the bar to curving shape, and applying timely treatment, mechanical processing and surface processing. It reduces mold cost and processing cost, improved product quality and efficiency, with less continuous processing difficulty.

Description

technical field [0001] The invention relates to the field of manufacturing and processing mechanical workpieces, in particular to a method for manufacturing a C-shaped arm. Background technique [0002] Fixed and mobile C-arm X-ray machines are often used for digital photography or filming of patients in cardiac and peripheral vascular interventional therapy and orthopedic surgery. This equipment can also be used in certain special research applications. [0003] In the prior art, the conventional manufacturing process including the C-arm is: [0004] (1) According to the design size of the C-arm, first make a casting mold of the same size. This mold is usually made of wood. [0005] (2) Using the pouring method, the aluminum alloy is poured into the C-arm mold, and cooled and formed. [0006] (3) Perform aging treatment, mechanical processing, and surface treatment on the castings obtained in step (2) in sequence to obtain finished products. [0007] Such prior art man...

AI Technical Summary

Problems solved by technology

[0008] (1) poor mold precision

The original size of the usual C-arm wooden mold is large, the mold production cycle is long, and the production accuracy is low;

[0009] (2) The quality of the finished product is poor

The casting method is used in the production process, and the product has low density uniformity, poor tensile and bending resistance after forming, and honeycomb pores often appear, making the inner and outer surfaces of the product rough;

[0010] (3) Difficult to process

For the C-arm obtained by the casting method, the casting size is usually reserved larger, and the pouring port and vent hole must be reserved in the process, and the inner and outer surfaces of the shape are rough, so the machining difficulty is increased, the time period is long, and the processing time is long. high cost;

[0011] (4) High processing cost

[0012] (5) Low production efficiency
