Description

The square axle sleeve of a kind of band square hole and processing method thereof and application
Technical field
The invention belongs to the processing technique field of metal parts, be specifically related to the square axle sleeve of a kind of band square hole And processing method and application.
Background technology
Along with the development of auto industry, main engine plants the technology of angle regulating device for seat of vehicle is required such as bearing strength, Process structure, product quality and production cost etc. require more and more higher.Domestic each big angle regulating device for seat of vehicle is looked forward to Industry all meets, in research and development, the recliner core component that technology requires.
The square shaft set of angle regulating device for seat of vehicle is as an important core component, and it includes square axle sleeve Body, in axial direction offers square opening and prism at square sleeve body, in prior art, and this square shaft set Traditional diamond-making technique mainly have following several:
(1) directly being processed manufacturing by the tubing of band center square hole, this processing method can reduce machining center The step of axis hole, but the square shaft nested structure intensity that this processing method manufactures is low;
(2) first it is processed into square axle sleeve, then to processing with engine lathe by metal bar (wire rod rolled product) Good square shaft sleeve semi-finished product line cutting carries out holing and reaming, but this technique production cost is higher, work People's labor intensity is big, and waste of material is serious, complex process and wayward, and the scope of application is little, it is impossible to meet The demand for development of current enterprise;
(3) use cold headers and the square axle sleeve of linear cutter, comprise the following steps: S1: the dish circle that will get ready Steel (metal bar) are placed on feeder equipment, and wire rod rolled product is sent into blanking in cold headers by feeder equipment; S2: by wire rod rolled product (metal bar) is first become cylinder with cold headers cold-heading;S3: process at S2 Cylinder on cold headers cold-heading manhole;S4: the circle then by line cutting, S3 processed is led to Hole machined squarely through hole, obtains this square shaft set;
(4) use cold headers and the square axle sleeve of lathe process, comprise the following steps: S1: the dish round steel that will get ready Material (metal bar) is placed on feeder equipment, and wire rod rolled product is sent into blanking in cold headers by feeder equipment;S2: By wire rod rolled product (metal bar) is first become cylinder with cold headers cold-heading;S3: the circle processed at S2 With cold headers cold-heading square through hole on cylinder;S4: the cylinder then by lathe or milling cutter, S2 processed External surface is processed into square, obtains this square shaft set.
In method (3) and method (4), cold headers are used to complete some steps in this square shaft set step Suddenly, but also need in this process use the technology such as line cutting, lathe or milling cutter just can complete square The processing of axle sleeve, and use line cutting, lathe or milling cutter processing higher to the skill requirement of workman, processing Time is long, and waste material is many, and the precision being easily caused core component is low, the problem that quality is unstable, and this processing The whole production technology of mode is discontinuous, and production efficiency is low, and processing cost is high.
At present, such square axle sleeve all the completeest appears in the newspapers with what cold headers machined.
It addition, directly process axle sleeve stock by cold headers there is quick, stable, precision advantages of higher, In the course of processing of standard component, it may be used for offering manhole on circular cylinder, or in circular columns Offer square through hole on body, or on square cylinder, offer manhole, and for opening on square cylinder If square opening, due to the restriction of plastic deformation inherently character, then have not been reported.
