Description
Technical Field
The utility model belongs to the technical field of the mold processing, a mould that is used for bolt polished rod and thread rolling footpath extrusion moulding particularly.
Background
Bolts are the most common type of fastener, and high temperature alloy bolts are widely used in aircraft engines. In the prior art, the processing method of the high-temperature alloy bolt is as follows: upsetting a bolt head, processing a bolt polish rod and a thread rolling diameter by turning to remove materials, grinding the polish rod and the thread rolling diameter, and finally rolling threads, wherein the upset section of part of the thread alloy bolt head is larger, so that a part is generally upset by selecting a material with a larger specification, and a large amount of rod materials are required to be removed in subsequent processes. The problems that are caused are: 1) the high-temperature alloy material has high hardness, when a large allowance of material is removed by turning (or grinding), a turning tool (or a grinding wheel) is quickly worn, the tool is frequently changed (or the grinding wheel is frequently repaired), and the processing efficiency is low; 2) the part removal allowance is large, and more material waste is generated; 3) the material removal allowance is large, the subsequent repair processing time is long, and the single piece processing efficiency is low.
Disclosure of Invention
The utility model aims to overcome above-mentioned shortcoming and provide a simple structure, high-efficient reliable, convenient operation, economical and feasible be used for bolt polished rod and thread rolling footpath extrusion moulding's mould.
The utility model discloses the purpose and solve its main technical problem and adopt following technical scheme to realize:
the utility model discloses a mould for bolt polished rod and thread rolling footpath extrusion moulding, including guide pin bushing, mould body, wherein: the upper portion of the die body is provided with a guide sleeve in a matched mode, a guide hole A is formed in the guide sleeve, a die sleeve is sleeved outside the die body, the lower end of the guide sleeve is attached to the upper end of the die body, an extrusion section A, a guide hole B, an extrusion section B and a guide hole C are sequentially arranged in the die body from top to bottom, the guide hole A, the guide hole B and the guide hole C are located on the same straight line, the extrusion section A is located between the guide hole A and the guide hole B, and the extrusion section B is located between the guide hole B and the guide hole C.
The die for extrusion forming of the bolt polish rod and the thread rolling diameter comprises: the extrusion section A and the extrusion section B are both composed of a conical section at the upper part and a cylindrical section at the lower part.
Compared with the prior art, the utility model obvious advantage and beneficial effect have. According to the technical scheme, in the die for extrusion forming of the bolt polish rod and the thread rolling diameter, the guide sleeve is arranged on the upper portion of the die body in a matched mode, the guide hole A is formed in the guide sleeve, the die sleeve is sleeved outside the die body, the lower end of the guide sleeve is attached to the upper end of the die body, a workpiece to be processed is conveniently placed in the guide hole A to be extruded, and a guide effect is achieved; the die body is internally provided with an extrusion section A, a guide hole B, an extrusion section B and a guide hole C from top to bottom in sequence, the center lines of the guide hole A, the guide hole B and the guide hole C are positioned on the same straight line, the extrusion section A is positioned between the guide hole A and the guide hole B, the extrusion section B is positioned between the guide hole B and the guide hole C, and the extrusion section A and the extrusion section B respectively realize the forming of a polished rod and a rolled wire diameter of a workpiece; extrusion section A and extrusion section B constitute by the toper section on upper portion and the cylinder section of lower part, and the work piece is by the coarse thinning in the work piece extrusion process more of being convenient for to the toper section, and the cylinder section is big than the bullport diameter of lower part usually, avoids the guide section to produce too big frictional force to influence the processing effect. In a word, the utility model discloses simple structure, high-efficient reliable, convenient operation, economical and feasible are fit for bolt polished rod and the use widely of rolling the footpath extrusion moulding.
