机床铸件的缺点修正介绍

关于机床铸件的大缺点，引荐传统焊补技术与锻造缺点修补机的复合应用。但锻造缺点修补机的焊补规模为Φ1.5-Φ1.2mm焊补点重复熔化堆积的进程，在大面积缺点修补进程中，修正功率是制约其广泛推广应用的仅有因素。世界盛行的热处理技术，使铸件的应力变形削减到最小度。持久运用更趋于稳定。

经过对几种传统焊补技术在机床铸件缺点处的修补成果，分析机床铸件修正成果欠安的原因。经过对锻造缺点修补机在机床铸件的修正成果的研究，断定一种的确可行的在机床铸件上修正的新技术及其技术。使用锻造缺点修补机对锻造件的缺点进行修正，铸件在修正进程中，不升温、不变形、无裂纹发生、焊补点金属细密，不发僵硬点、无退火表象，能够进行任何机械加工。补材的选择不受原料的制约，经过不一样原料补材的选择，能够到达焊补点功能、色彩与母体上的一致。补材与母体为冶金联系，联系强度高，不会发生掉落焊补质量契合机床铸件产品的质检规范，是值得广泛推广的一种新技术。

机床铸件原料均为优质细腻的灰口铸铁HT200-HT300，采用世界盛行的热处理技术，使铸件的应力变形削减到最小度。持久运用更趋于稳定。精准的配比，更高的抗拉抗弯强度。其选用树脂砂、消失模实型锻造，单件到达40吨以上，年生产值在8500吨左右。包括机床床身、工作台、立柱、横梁、龙门顶衔接梁。

Introduction to the Defect Correction of Machine Tool Castings

For the major shortcomings of machine tool castings, this paper introduces the composite application of traditional welding repair technology and forging defect repair machine. However, the welding repair scale of forging defect repairing machine is 1.5-1.2mm welding point repeated melting accumulation process. In the process of large area defect repairing, the correction power is the only factor restricting its wide application. The world's prevailing heat treatment technology minimizes the stress and deformation of castings. Persistent use tends to be more stable.

After repairing the defects of machine tool castings with several traditional welding repair technologies, the reasons for the unsafe results of machine tool castings correction are analyzed. After studying the results of the modification of forging defect repairing machine for machine tool castings, a new technology and its technology for determining the feasibility of the modification of machine tool castings are determined. The defects of forgings are corrected by using forging defect repairing machine. In the process of correcting, the casting can be machined without heating, deformation, crack occurrence, fine metal of weld joint, stiffness point and annealing appearance. The selection of filler is not restricted by the raw materials. Through the selection of different filler materials, the function and color of the solder joint can be consistent with that of the parent body. The metallurgical connection between the repairing material and the matrix is a new technology worthy of wide promotion, which has high connection strength and does not occur dropping welding repairing quality, which conforms to the quality inspection standard of machine tool castings.

The raw materials of machine tool castings are high quality gray cast iron HT200-HT300. The stress and deformation of the castings are minimized by using the world's prevailing heat treatment technology. Persistent use tends to be more stable. Accurate ratio, higher tensile and flexural strength. Resin sand and lost foam solid forging are selected. The single piece reaches over 40 tons, and the annual production value is about 8500 tons. Including machine tool bed, worktable, column, cross beam, gantry top connection beam.
