AI Technical Summary

Problems solved by technology

The bed and column castings are single-cast, and the quality of the castings is very stable, and the pass rate is above 98%. Since the bed and column are individually finished, there will be a fit gap between the bed and the column during the machine tool assembly process. Mismatch and other problems lead to casting scrap
[0003] So far, there is no way to overcome the above drawbacks

Embodiment Construction

[0026] A column and bed one-piece casting method, the method includes design, core making, molding, box closing, pouring and box cleaning, such as figure 1 , 2 , Shown in 3 and 4: the above scheme is that the bed guide rail is placed below, the column guide rail is placed on the side, and the column and the bed are in the same box and are taken out by the outer belt.

[0027] The patterns in the molding are divided into an upper pattern, a lower pattern, and a rear pattern, and the above three patterns are respectively riveted on three flat plates to form an upper template 1, a lower template 2 and a rear template 4, and then two flat panels are made, respectively. It is defined as front formwork 3 and side formwork 5, design positioning pins at corresponding positions of lower formwork 2 and front formwork 3, design positioning pins at corresponding positions of rear formwork 4 and side formworks 5; sand box in the described molding There are three pairs: 1# sand box, 2# san...

Abstract

The invention relates to a method for integrally casting two or more castings and particularly relates to a method for integrally casting an upright post and a lathe bed. The method comprises the following steps: scheme designing, core manufacturing, shaping, mold assembling, pouring and mold dismantling and cleaning. The method is characterized in that according to a scheme, a latch bed guide rail is arranged at the bottom, an upright post guide rail is arranged at the side surface, and the upright post and the lathe bed are arranged in a same box and are brought out through an outer skin. The method is unique; by utilizing the method, the sand-iron ratio is reduced, the cost is saved, and the production efficiency is increased.

Description

technical field [0001] The present invention relates to two or more kinds of cast pieces conjoined casting method, especially relates to a column, bed body conjoined casting method. Background technique [0002] One-piece casting, is connected by bolts. The single casting structure is relatively simple, and the manufacturing technology is very mature. For example, the bed casting process usually places the guide rail surface below the pouring position, and adopts a closed bottom surface inflow pouring system. The column casting process usually places the guide rail surface below the pouring position. , a closed pouring system is adopted, and the flow enters along the end of the column guide rail. The bed and column castings are single-cast, and the quality of the castings is very stable, and the pass rate is above 98%. Since the bed and column are individually finished, there will be a fit gap between the bed and the column during the machine tool assembly process. Mismatc...
