機床鑄件的缺點修正介紹

關于機床鑄件的大缺點，引薦傳統(tǒng)焊補技術與鍛造缺點修補機的復合應用。但鍛造缺點修補機的焊補規(guī)模為Φ1.5-Φ1.2mm焊補點重復熔化堆積的進程，在大面積缺點修補進程中，修正功率是制約其廣泛推廣應用的僅有因素。世界盛行的熱處理技術，使鑄件的應力變形削減到最小度。持久運用更趨于穩(wěn)定。

經(jīng)過對幾種傳統(tǒng)焊補技術在機床鑄件缺點處的修補成果，分析機床鑄件修正成果欠安的原因。經(jīng)過對鍛造缺點修補機在機床鑄件的修正成果的研究，斷定一種的確可行的在機床鑄件上修正的新技術及其技術。使用鍛造缺點修補機對鍛造件的缺點進行修正，鑄件在修正進程中，不升溫、不變形、無裂紋發(fā)生、焊補點金屬細密，不發(fā)僵硬點、無退火表象，能夠進行任何機械加工。補材的選擇不受原料的制約，經(jīng)過不一樣原料補材的選擇，能夠到達焊補點功能、色彩與母體上的一致。補材與母體為冶金聯(lián)系，聯(lián)系強度高，不會發(fā)生掉落焊補質(zhì)量契合機床鑄件產(chǎn)品的質(zhì)檢規(guī)范，是值得廣泛推廣的一種新技術。

機床鑄件原料均為優(yōu)質(zhì)細膩的灰口鑄鐵HT200-HT300，采用世界盛行的熱處理技術，使鑄件的應力變形削減到最小度。持久運用更趨于穩(wěn)定。精準的配比，更高的抗拉抗彎強度。其選用樹脂砂、消失模實型鍛造，單件到達40噸以上，年生產(chǎn)值在8500噸左右。包括機床床身、工作臺、立柱、橫梁、龍門頂銜接梁。

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.
