Abstract
The invention belongs to the field of loading machine accessories, and discloses a forging technology for a middle shaft of a loading machine. The forging technology comprises the following steps that firstly, a free forging blank is cut; then, upsetting is formed, upsetting is adopted in free forging firstly, in an upsetting working procedure, an application size is unchangeable, and therefore metal flows to the middle, and the requirement for the largest section of the middle is met; two-time roll-forming is carried out, through pressing of a mold, the two ends are drawn to be long, after first-time roll-forming is finished, a forge part is rotated by 90 degrees, then, extrusion is carried out, and the forge part is extruded to be in a regular shape; and final forging, the forge part obtained through two-time extruding is finally forged, side cutting treatment is carried out on the part obtained after final forging finally, and forging treatment is finished. The forging technology has the advantages of being simple in technology and good in forging quality.
Description
Technical field
The invention belongs to loading machine accessory field, be specifically related to loading machine jackshaft Forging Technology.
Background technology
Loading machine belongs to earth moving machinery class, is a kind ofly to support result and connecting rod random device and travel forward by being arranged on the complete scraper bowl in one, front end and carry out loading or excavating, and promotes, the self-propelled crawler belt of transport and unloading or tire machinery.Have that the fast efficiency of operating speed is high, mobility operates the advantages such as light well.Jackshaft is the critical piece of loading machine, and its major function cooperatively interacts with each gear of main shaft, and realize the transmission speed that loading machine is different, the duration of runs is long, easily occurs distortion and wearing and tearing.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of loading machine jackshaft Forging Technology, has technique simple, the feature that forging quality is good.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of loading machine jackshaft Forging Technology, comprises the steps, first cuts open die forging base; Then be shaped jumping-up, first carries out jumping-up by open die forging, applies constancy of volume in jumping-up operation, makes metal to intermediate flow, reaches the requirement of middle maximum cross-section; Two passage edgings, reach two ends pulling by pressing down of mould, are extruded by forging 90-degree rotation after the first passage completes again, make forging be squeezed into the shape of rule; Finish-forging, the forging of two passage extruding is carried out finish-forging, and finally carry out trimming process to the forging after finish-forging, conducting forging processing is complete.
Further, billet size is φ 64 X 254-φ 64 X 258mm.
Compared with prior art, the present invention has following beneficial effect:
Present invention process is simple to operate, decreases operation easier, improves operating efficiency, improves the quality of forging products.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
A kind of loading machine jackshaft of embodiment Forging Technology, comprises the steps, first open die forging base; Then be shaped jumping-up, first carries out jumping-up by open die forging, applies constancy of volume in jumping-up operation, makes metal to intermediate flow, reaches the requirement of middle maximum cross-section; Two passage edgings, reach two ends pulling by pressing down of mould, are extruded by forging 90-degree rotation after the first passage completes again, make forging be squeezed into the shape of rule; Finish-forging, the forging of two passage extruding is carried out finish-forging, and finally carry out trimming process to the forging after finish-forging, conducting forging processing is complete.
Further, blank is Q235 or the Q345 carbon steel material of size φ 64 X 254-φ 64 X 258mm.
Last it is noted that the foregoing is only explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
