Abstract
The invention provides a driving cylindrical gear cone tooth and end tooth forging die frame and a forging method. The die frame adopts the structure that an upper die is mounted at the lower part of an upper die frame through a cushion cover and an upper stress ring, and a lower die is mounted at the upper part of the lower die frame through a cushion cover and a lower stress ring; guide posts are mounted between the upper die frame and the lower die frame, the lower parts of the guide posts are mounted at the upper part of the lower die frame through lubricant guide sleeves, and a die positioning opening is formed between the two guide posts; and two clamping rings mounted on a die lifting bar are respectively in contact connection with the upper stress ring and the lower stress ring. The forging method is used for making end products through procedures of blanking, blank processing, heating, stamping, heat treatment and surface cleaning. After the adoption of the die frame and the forging method, the forging quality is improved, the costs in raw material forging and machining are saved, end product waste is avoided, and the production efficiency is improved. The driving cylindrical gear cone tooth and end tooth forging die frame is suitable for driving cylindrical gear cone tooth and end tooth forging in truck bridge triple gear.
Description
Technical field
The present invention is to provide forging and the processing method of heavy truck jackshaft three teeth, specifically initiatively roller gear awl tooth and end tooth forge mould bases and forging method.
Background technology
At present, the jackshaft of domestic heavy truck bridge adopts three tooth transmissions, wherein, initiatively the FMT of roller gear awl tooth has a long way to go with abroad comparing, mainly be that domestic equipment for forging product can not guarantee the initiatively forging requirement of roller gear awl tooth, therefore raw-material utilization rate is low, the machining cost height, and properties of product are low.Initiatively the forging method operation of roller gear awl tooth product can not be finished bevel gear part and the requirement of shaping simultaneously of end tooth part simultaneously.
Summary of the invention
In order to overcome the defective of existing initiatively roller gear awl tooth and end tooth processing, the present invention proposes active roller gear awl tooth and end tooth and forge mould bases and forging method.This mould bases be by boring tooth and end tooth is shaped simultaneously, solve the coaxial technical problem with machining accuracy with end tooth of awl tooth.
The scheme that technical solution problem of the present invention adopts is:
Initiatively roller gear is bored tooth and end tooth forge mould shelf structure:
Patrix is equipped with by cushion cover and upper stress circle in the top mold frame bottom, and counterdie is equipped with by cushion cover and following circle stress in following mould bases top; Up and down between the mould bases guide pillar is being housed, the bottom of guide pillar is installed in down the top of mould bases by the lubricating oil guide pin bushing, is provided with the mould positioning port between two guide pillars; Being contained in two trim rings on the mould elevating lever contacts with following circle stress with the upper stress circle respectively and is connected.
Initiatively roller gear is bored tooth and end tooth forging method:
1, blanking: carry out cylinder round steel blank by the bimetallic strip sawing machine, form blank;
2, blank carries out chamfer machining by engine lathe, and the unhairing limit forms smart blank;
3, heating: under 1100-1150 ℃, smart blank is carried out heat fusing by the heating in medium frequency stove, form liquid material;
4, die forging: the liquid state material is injected grinding tool, forge mould bases blocking awl tooth and end tooth by active roller gear awl tooth and end tooth, the overlap that falls again processing forms and forges material;
5, heat treatment: will forge material and carry out the waste heat isothermal normalizing;
6, removing surface: to carrying out removing surface through Overheating Treatment to forging material, form initiatively roller gear awl tooth and end tooth finished product by shot-peening.
Good effect adopts forging mould bases of the present invention and forging method can improve the quality of forging, saves forging raw material and machining cost, avoids the waste of finished product, enhances productivity.Suitable to using in truck bridge three teeth active roller gear awl tooth and the end tooth forging.
