Embodiment Construction

[0020] A method for casting super-long and large-scale machine tool castings is characterized in that it includes the following steps:

[0021] a. Pit preparation: Lay cast iron plates on the bottom and sides of the pit, and lay two steel rails on the cast iron plates at the bottom;

[0022] b. Make the casting model: make a simple wooden frame to form the appearance of the casting that is difficult to mold and all complex parts are all made of EPS material. When making the model, leave 1~2mm according to the length from both ends to the middle part along the length of the casting. The anti-deformation amount of / m increases the space of the floor board by 4-8mm;

[0023] c. Modeling and core making: Before modeling, first level the three bottom cores with a level ruler, and at the same time align the side teeth, pre-embed core iron rods on both sides during modeling, and place the air outlet pipe at the highest point of the casting;

[0024] d. Lower core: place a 30mm colum...

Abstract

The invention relates to a method for casting a machine tool casting, in particular to a method for casting an overlong large machine tool casting. The invention is characterized in that the method comprises the steps as follows: preparing a pit, manufacturing a casting model, molding, making a core, pressing a box, pouring, shaking out sand normally and blasting ball. The invention provides the method for casting the overlong large machine tool casting. The technical method is unique, combines EPS with a wood pattern main frame mold and uses a casting technology of molding in the pit, and the invention can reduce the expense for producing tool equipment and solve the casting difficulty that the overlong large casting has the size problems such as being deformed easily during the production.

Description

technical field [0001] The invention relates to a casting method of machine tool castings, in particular to a casting method of super-long and large machine tool castings. Background technique [0002] At present, for large-scale machine tool castings with a length ≥ 9000mm, a weight ≥ 17t, and a relatively small demand, conventional sandbox and wooden mold casting methods are used. Not only the cost is too high, the efficiency is low, and the casting is difficult, but the casting The castings that come out have casting problems such as easy deformation and other dimensional problems. The present invention adopts the pit molding method of part of the EPS mould, successfully reduces high production cost, improves production efficiency, solves casting problems such as easy deformation of castings, and successfully produces super long and large castings for customers. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of t...
