Problems solved by technology

[0002] The steering gear cabin and the control cabin are generally titanium alloy cylindrical parts. Due to their complex internal structure, many bosses, and large differences in wall thickness, there are many defects such as cracks and pores in the castings in the early development and production process. It has greatly affected the production progress of the product, and has become a bottleneck in the development and production of models, resulting in high manufacturing costs, and it is difficult to guarantee the development node, so it must be solved

Embodiment Construction

[0013] Below in conjunction with specific embodiment, further illustrate the present invention.

[0014] The specific implementation method of the titanium alloy tubular piece casting process provided by the embodiment of the present invention is as follows:

[0015] The pouring system of titanium alloy cylindrical parts adopts the top casting form, including a sprue cup, a sprue, two runners and 12 ingates. When the casting is poured, the liquid is introduced into the liquid flow from the top.

[0016] The invention includes pouring system design, graphite mold material selection, preparation, assembly, roasting process research, and titanium alloy vacuum consumable electrode coagulation melting process research.

[0017] TSK graphite is used for the graphite mold of titanium alloy cylindrical parts, and it is processed and assembled according to the gating system design.

[0018] The graphite mold of the assembled titanium alloy cylinder is in a vacuum of 6×10 -1 ~8×10 -1...

Abstract

The invention discloses a graphite type casting method of a cylindrical titanium alloy piece. The method comprises the following processing steps: (1) designing a barrel-type titanium alloy piece casting system; (2) preparing a graphite mould; (3) removing air out of the graphite mould; (4) enabling the graphite mould to form a casting mould according to a casting forming picture; and (5) carrying out titanium alloy vacuum consutrode kish melting process. The graphite type casting method provided by the invention has the advantages that the barrel-type titanium alloy piece with the qualified surface quality and mechanical property is successfully formed by pouring based on the research on graphite casting technology of the barrel-type titanium alloy casting, a condition that the barrel-type titanium alloy piece depends on a machining preparation manner is avoided, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a titanium alloy casting process, in particular to a graphite casting process for a titanium alloy cylindrical piece. Background technique [0002] The steering gear cabin and the control cabin are generally titanium alloy cylindrical parts. Due to their complex internal structure, many bosses, and large differences in wall thickness, there are many defects such as cracks and pores in the castings in the early development and production process. It has greatly affected the production progress of the product, and has become a bottleneck in model development and production, resulting in high manufacturing costs and difficult guarantee of development nodes, which must be resolved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a suitable casting process for titanium alloy cylindrical parts, so that it can cast titanium alloy cylindrical parts with qualified surface qu...
