Abstract
The invention belongs to loading machine accessories fields, disclose a kind of forging technology of jackshaft anti-extrusion, include the following steps, cut open die forging base first；Then jumping-up is shaped, jumping-up is first carried out by open die forging, applies constancy of volume in jumping-up process, makes metal to intermediate flow, reaches intermediate maximum cross-section and require；Two passage edgings reach both ends pulling by the pushing of mold, are rotated by 90 ° forging after the completion of the first passage and squeeze again, forging is made to be squeezed into the shape of rule；Finish-forging, the forging that two passages are squeezed carry out finish-forging, finally carry out trimming processing to the forging after finish-forging, and conducting forging processing finishes.With simple process, the good feature of forging quality.
Description
Technical field
The invention belongs to loading machine accessories fields, and in particular to loading machine jackshaft forging technology.
Background technique
Loading machine belongs to earth moving machinery class, be it is a kind of by be mounted on the complete scraper bowl in front end one support result with
Connecting rod random device, which travels forward, to be loaded or excavates, and is promoted, the self-propelled crawler belt or tire machinery of transport and unloading.Tool
It is light to have the advantages that the fast high-efficient, mobility of operating speed operates well.Jackshaft is the main component of loading machine, its main function
Can cooperate with each gear of main shaft, realize the different transmission speed of loading machine, the duration of runs is long, easily occurs deforming and grind
Damage.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, a kind of forging technology of jackshaft anti-extrusion is provided, there is work
Skill is simple, the good feature of forging quality.The purpose of the present invention is achieved by the following technical scheme: a kind of jackshaft is anti-extrusion
The forging technology of pressure, includes the following steps, cuts open die forging base first；Then jumping-up is shaped, jumping-up is first carried out by open die forging,
Constancy of volume is applied in jumping-up process, is made metal to intermediate flow, is reached intermediate maximum cross-section and require；Two passage edgings, pass through
The pushing of mold reaches both ends pulling, is rotated by 90 ° forging after the completion of the first passage and squeezes again, forging is made to squeeze established practice
Shape then；Finish-forging, the forging that two passages are squeezed carry out finish-forging, finally carry out trimming processing, forging to the forging after finish-forging
It is disposed.Further, billet size is φ 64X 254- φ 64X 258mm.Compared with prior art, the present invention has
It is following the utility model has the advantages that present invention process is easy to operate, reduce operation difficulty, improve work efficiency, improve forging production
The quality of product.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described, it should be understood that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.A kind of forging technology of jackshaft anti-extrusion of embodiment, including such as
Lower step, first open die forging base；Then jumping-up is shaped, jumping-up is first carried out by open die forging, applies constancy of volume in jumping-up process,
Make metal to intermediate flow, reaches intermediate maximum cross-section and require；Two passage edgings reach both ends pulling by the pushing of mold,
Forging is rotated by 90 ° after the completion of first passage and is squeezed again, forging is made to be squeezed into the shape of rule；Finish-forging squeezes two passages
The forging of pressure carries out finish-forging, finally carries out trimming processing to the forging after finish-forging, and conducting forging processing finishes.Further, blank is
Q235 the or Q345 carbon steel material of size φ 64X 254- φ 64X 258mm.Finally, it should be noted that the foregoing is merely explanations
Embodiments of the present invention are not intended to restrict the invention, for those skilled in the art, all in spirit of the invention
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
