Description

A kind of square axle sleeve with square hole and its processing method and application

Technical field

The invention belongs to the processing technique field of metal parts, it is specifically related to a kind of square axle sleeve with square hole and its adds Work methods and applications.

Background technique

With the development of the automobile industry, technical requirements such as bearing strength, technique knot of the main engine plants to angle regulating device for seat of vehicle Structure, product quality and production cost etc. require higher and higher.Domestic major angle regulating device for seat of vehicle enterprise all accords in research and development Close the angle adjustor core component of technical requirements.

The square axle sleeve that angle regulating device for seat of vehicle is used is as an important core component comprising square axle sleeve ontology, Square opening and prism is in axial direction opened up in square axle sleeve ontology, in the prior art, the traditional diamond-making technique master of the square axle sleeve Have following several:

(1) it is directly fabricated by the tubing with center square hole, which can reduce machining center axis hole The step of, but the square axle sleeve structural strength of processing method manufacture is low;

(2) engine lathe processing squarely axle sleeve is first used by metal bar (wire rod rolled product), then to the side processed Shape shaft sleeve semi-finished product carries out drilling and reaming with wire cutting, but the technique production cost is higher, and labor intensity of workers is big, material Waste is serious, complex process and not easy to control, and the scope of application is small, is unable to satisfy the demand for development of current enterprise;

(3) cold headers and linear cutter square axle sleeve are used, comprising the following steps: S1: by the wire rod rolled product got ready (gold Belong to bar) it is placed on feeder equipment, wire rod rolled product is sent into blanking in cold headers by feeder equipment;S2: by wire rod rolled product (gold Belong to bar) first with cold headers cold-heading at cylindrical body;S3: cold headers cold-heading circular through hole is used on the cylindrical body that S2 is processed;S4: Then square through hole is processed into get the square axle sleeve by the circular through hole that wire cutting processes S3;

(4) cold headers and lathe process square axle sleeve are used, comprising the following steps: S1: the wire rod rolled product (metal that will be got ready Bar) it is placed on feeder equipment, wire rod rolled product is sent into blanking in cold headers by feeder equipment;S2: by wire rod rolled product (metal Bar) first with cold headers cold-heading at cylindrical body;S3: cold headers cold-heading square through hole is used on the cylindrical body that S2 is processed;S4: so Squarely is processed to get the square axle sleeve by the cylindrical outer surface that lathe or milling cutter process S2 afterwards.

In method (3) and method (4), some steps in the square axle sleeve step are completed using cold headers, but It also needs to complete the processing of square axle sleeve during this using technologies such as wire cutting, lathe or milling cutters, and uses line Cutting, lathe or milling cutter processing are higher to the skill requirement of worker, and long processing time, waste material is more, is easy to cause core component Precision it is low, the problem of unstable quality, and the entire production technology of the processing method is discontinuous, and production efficiency is low, is processed into This height.

Currently, such square axle sleeve all also complete is appeared in the newspapers with what cold headers completed the process.

In addition, directly processing axle sleeve embryo material by cold headers has many advantages, such as that quick, stable, precision is high, in standard component In process, it can be used for opening up circular through hole on circular cylinder, or square through hole is opened up on circular cylinder, or Person opens up circular through hole on square cylinder, and for opening up square hole on square cylinder, inherently due to plastic deformation The limitation of property, then have not been reported.
