Abstract
The invention relates to a forging and machining process of a lower bracket connection fork of a vehicle power assembly and aims at providing a forging process of the lower bracket connection fork. The process is used for remarkably improving the machining efficiency and the product performances. The forging process of the lower bracket connection fork is characterized by comprising the following steps of: heating up round bar steel to 1050 DEG C to 1100 DEG C by an electric heating furnace; and forging the round bar steel into a finished product within 45 seconds. Preferably, the round bar steel is heated up to 1085 DEG C to 1093 DEG C by the electric heating furnace. According to the forging process of the lower bracket connection fork disclosed by the invention, simple process improvement is adopted, existing equipment is utilized, and process indexes are adjusted in a varying manner and precisely controlled, so that the product machining period is shortened, and the product machining efficiency and the product performances are improved.
Description
Technical field
The lower carriage yoke that the present invention relates on vehicle engine assembly forges processing.
Background technology
In prior art, lower carriage yoke Forging Technology process is substantially, and take round steel as raw material, first heating forges into crude green body, and then heating forges and is finished product.The general gas furnace that adopts of heating heats.And the temperature of gas furnace heating is uneven, is oxidation reaction process because combustion of natural gas is actual, also easily causes simultaneously decarburization.Whole process is complicated, and long flow path makes the metal inside tissue change uneven and poor moving, and crystal grain increases; The toughness of product, plasticity, tensile strength etc. all will be subject to impact in various degree, and making has certain impact in product quality and service life.
And the explained hereafter cycle that such twice heating forges is long, and is uneconomical at everyways such as time of delivery node, human resources, processing costs, do not save, and produces unnecessary internal consumption.
Summary of the invention
Main purpose of the present invention is to provide a kind of lower carriage yoke Forging Technology, and this technique significantly improves working (machining) efficiency and properties of product.
For achieving the above object, the technical solution adopted in the present invention is: lower carriage yoke Forging Technology is characterized in that:, then in 45 seconds, round steel is forged and be finished product to 1050-1100 ℃ with electric furnace heating round steel.
Preferably, the described process that forges is: forge into crude green body in 30 seconds, in 15 seconds, crude green body is forged into finished product.
Preferably, described electric furnace heating round steel is to 1085-1093 ℃.
The present invention adopts simple process modification, utilizes existing equipment, by the adjustment of technic index and accurately control, has shortened the product process-cycle, has improved the performance of product working (machining) efficiency and product.Forging temperature improves and the control that forges the time can guarantee that product all is in and forges the requiring under process conditions of processing in whole forging process, completes smoothly and forges processing.And the forging cycle shortens the risk that can reduce burning.Change existing heated by natural gas into heating by electric cooker and can accurately control heating-up temperature, the oxidizing substance of also avoiding fuel gas buring to produce causes the problem of material decarburization.Therefore technique of the present invention by control and the assurance of temperature, time index, has reduced operation; Make the variation of metal inside tissue obtain effective control in forging process, grain deformation reduces, and the metal inside tissue changes evenly, makes the toughness, plasticity, tensile strength etc. of product obtain effective raising, reach the assurance of product quality and stable, improved product service life.
The specific embodiment
Take round steel as original material, the lower carriage yoke on the processing vehicle engine assembly adopts and forges processing technology.
At first with electric furnace heating round steel to 1085 ℃, forge into crude green body immediately, the time was controlled in 30 seconds; Then crude green body is forged into finished product, the time was controlled in 15 seconds; The whole forging process time was controlled in 45 seconds.
The forging cycle shortens the risk that can reduce burning.Change existing heated by natural gas into heating by electric cooker and can accurately control heating-up temperature, the oxidizing substance of also avoiding fuel gas buring to produce causes the problem of material decarburization.Therefore technique of the present invention by control and the assurance of temperature, time index, has reduced operation; Make the variation of metal inside tissue obtain effective control in forging process, grain deformation reduces, and the metal inside tissue changes evenly, makes the toughness, plasticity, tensile strength etc. of product obtain effective raising, reach the assurance of product quality and stable, improved product service life.
