Abstract
The invention discloses a kind of forging method of cylindrical element, it is related to machinery manufacturing technology field；Comprise the following steps：The process such as blanking, heating, jumping-up and pulling, reheating, punching and reaming, shaping, cooling.The present invention can solve the problems, such as current cylindrical element bad mechanical property.
Description
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of forging method of cylindrical element.
Background technology
Forging is that one kind applies pressure using metal forming machinery to metal stock, it is produced plastic deformation to obtain with one
Determine mechanical performance, the processing method of shape and size forging；It is loose that forging can eliminate metal caused as cast condition in smelting process
The defects of, optimize heterogeneous microstructure, retain complete metal streamline；In field of machining, zero of critical function is undertaken
Part often uses forging；At present, cylindrical component carries out machining using bar more and formed, but due to this bar without
Crossing forging improves tissue, and obtained cylindrical element mechanical performance is poor, is not used in important occasion.
The content of the invention
It is an object of the invention to provide a kind of forging method of cylindrical element, and it can solve current cylindrical element bad mechanical property
The problem of.
In order to solve the above problems, the technical solution adopted by the present invention is：A kind of forging method of cylindrical element, including it is as follows
Step：
1）Blanking：Choose appropriate diameter bar cut off to length material section；
2）Heating：Material section is heated in intermediate frequency furnace, heating and temperature control is at 1150 DEG C ± 50 DEG C and insulation 1.5 hours ~ 2 is small
When, it is ensured that material section internal and external temperature is uniform；
3）Jumping-up and pulling：The material section heated is subjected to jumping-up and pulling with forging hammer, and controls length and diameter, final forging temperature
Control is at 1000 DEG C ± 50 DEG C；
4）Reheat：The good material section of jumping-up is sent into intermediate frequency furnace and reheated, heating and temperature control at 1150 DEG C ± 50 DEG C,
And it is incubated 1 hour ~ 1.5 hours；
5）Punching and reaming：The material base heated is put into forging die to be punched out, reaming is carried out by reaming frame after punching；
6）Shaping：Material base after reaming is subjected to shaping, makes up to size requirement, control final forging temperature is at 900 DEG C ~ 950 DEG C
Scope；
7）Cooling：The material base that shaping is completed is put into air and carries out Slow cooling.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the present invention improves tissue by forging, then is punched out, and the process such as reaming, finally obtains cylindrical element；
2nd, the cylindrical element tissue produced of the present invention is closely knit, better mechanical property.
Brief description of the drawings
Fig. 1 is the front view of cylindrical element of the present invention.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
A kind of forging method of cylindrical element, cylindrical element is as shown in figure 1, comprise the following steps：
1）Blanking：Choose appropriate diameter bar cut off to length material section；
2）Heating：Material section is heated in intermediate frequency furnace, heating and temperature control is at 1150 DEG C ± 50 DEG C and insulation 1.5 hours ~ 2 is small
When, it is ensured that material section internal and external temperature is uniform；
3）Jumping-up and pulling：The material section heated is subjected to jumping-up and pulling with forging hammer, and controls length and diameter, final forging temperature
Control is at 1000 DEG C ± 50 DEG C；
4）Reheat：The good material section of jumping-up is sent into intermediate frequency furnace and reheated, heating and temperature control at 1150 DEG C ± 50 DEG C,
And it is incubated 1 hour ~ 1.5 hours；
5）Punching and reaming：The material base heated is put into forging die to be punched out, reaming is carried out by reaming frame after punching；
6）Shaping：Material base after reaming is subjected to shaping, makes up to size requirement, control final forging temperature is at 900 DEG C ~ 950 DEG C
Scope；
7）Cooling：The material base that shaping is completed is put into air and carries out Slow cooling.
