Abstract

The utility model relates to a kind of parts of dynamic power machine, especially a kind of tech for starting gear shaft of diesel engine, in order to solve the problems, such as that existing tech for starting gear shaft of diesel engine cannot save material very well, a kind of tech for starting gear shaft of diesel engine is provided, axis body one end has crank way made of cold-heading, the axis body other end also has the section material fabrication hole that diameter made of cold-heading is 12~20mm, depth is 20~40mm, and the utility model energy material-saving 25% or so, saving working hour and less manpower take 20% or so.

Description

A kind of tech for starting gear shaft of diesel engine

Technical field

The utility model relates to a kind of part of dynamic power machine, especially a kind of tech for starting gear shaft of diesel engine.

Background technique

S195 diesel engine be it is a kind of it is with a long history, using extensive diesel engine, the part of diesel engine has had traditional Design and processing technology, the diesel engine have starter gear shaft, have the starter receiver of crank way and installation in starter gear shaft, Structure such as attached drawing 1, the method which mostly uses greatly hot-forging forming at present also have less use punching machine or press machine knot The technique that cold extrusion die carries out cold-extruded processing is closed, both techniques are because considering comprehensive process cost, in terms of stock utilization It is unsatisfactory.

Utility model content

Technical problem to be solved by the utility model is: cannot be saved very well to solve existing tech for starting gear shaft of diesel engine About material the problem of, a kind of tech for starting gear shaft of diesel engine is provided.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of tech for starting gear shaft of diesel engine, axis body One end has crank way made of cold-heading, and the axis body other end also has that diameter made of cold-heading is 12~20mm, depth is The section material fabrication hole of 20~40mm.

Preferably, the section material fabrication hole is φ 15X35mm.

The utility model has the beneficial effects that a kind of tech for starting gear shaft of diesel engine of the utility model, in multi-station cold-heading It is processed on machine, multi-station mold and multiple manipulator of the cold headers with arrangement, cold headers work is primary to be completed from blank to out The overall process of finished product makes fabrication hole of the other end processing one in starter gear shaft relative to crank way for the purpose of saving material in this way Design as a convenient and fast means, in this way section material fabrication hole overcomes existing technology prejudice, if because existing technique Processing such section material hole will increase mold investment, annealing steps and artificial investment etc., and increased processing cost is made to be higher than institute The fee of material that can be saved, so for a long time, those skilled in the art never design such section in starter gear shaft Material hole, the applicant feels free to try to be succeeded using the entire starter gear shaft of cold-heading technology processing, makes to increase section material fabrication hole It is possibly realized, the intensity that both can guarantee starter gear shaft entirety, the self weight for also mitigating starter gear shaft also save material, root It is continuous and quick with multistage cold former according to the tech for starting gear shaft of diesel engine energy material-saving 25% or so of test the utility model Repeatedly molding, does not need the process that product is made annealing treatment in process, can saving working hour and less manpower take it is left 20% The right side, the product of applicant has obtained the highly recognition of domestic large-scale diesel engine factory such as Changzhou Diesel Engine Factory at present.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the cross-sectional view of existing product.

Fig. 2 is the cross-sectional view of the utility model.

In figure: 1. axis bodies, 2. crank ways, 3. section material fabrication holes.

Specific embodiment

The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.

A kind of tech for starting gear shaft of diesel engine shown in Fig. 2, the axis body 1 with a cylindrical type, in one end of axis body 1 with cold Upsetting technique processes crank way 2, and the other end of axis body 1 equally processes section material fabrication hole 3 with cold heading technique, saves material fabrication hole 3 Diameter is 12~20mm, depth is 20~40mm.

It is tested repeatedly, scheme when material fabrication hole 3 is processed into φ 15X35mm under the premise of guaranteeing finished product integral strength It is optimal.

All works can be completed in time processing far faster than hot-working and cold stamping, raw material for the process velocity of cold-heading Sequence, eliminate heating back and forth and the step of annealing softening material thus a large amount of time and material consumption can be saved.

It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims Property range.
