Abstract
The invention discloses a production process for an oil pump nozzle. The production process for the oil pump nozzle is characterized by comprising the following steps of 1, blanking; 2, hot upsetting; 3, turning, 4, carburizing; 5, quenching; 6, tempering; 7, cold treatment; 8, grinding; 9, aging treatment; 10, lapping; and 11, assembling. The oil pump nozzle prepared through the production process is good in rigidity, hardness, abrasion resistance, fatigue strength and toughness.
Description
Technical field
The present invention relates to the production technique of a kind of oil pump nozzle.
Background technology
Along with the development of industry, the consumption of oil pump nozzle gets more and more, and distortion and the cracking of workpiece easily occurs in the oil pump nozzle of the production technique manufacture of existing a kind of oil pump nozzle, and rigidity, hardness, wear resistance, fatigue strength and toughness are not enough all to some extent.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide the production technique of a kind of oil pump nozzle, and oil pump nozzle rigidity, hardness, wear resistance, fatigue strength and toughness that this technique makes are all relatively good.
For achieving the above object, the present invention provides the production technique of a kind of oil pump nozzle, it is characterised in that, comprise the steps, 1) blanking; 2) temperature upsetting; 3) Vehicle Processing; 4) carburizing; 5) quench; 6) tempering; 7) deepfreeze; 8) mill processing; 9) ageing treatment; 10) grind; 11) assemble.
Further, described temperature pier is 400 DEG C ~ 600 DEG C in temperature to carry out temperature pier.
Further, described carburizing refers to and is incubated more than 60 minutes after workpiece is preheated to 925 DEG C, keeps carbon gesture 0.78 ~ 1.24 during this.
Further, described quenching refers to the quenching oil quench cooled that the gear of taking-up is put into 300 DEG C-350 DEG C, continues 0.5 hour, takes out gear air-cooled to room temperature.
Further, described tempering is, after workpiece quenching, reheating 500 ~ 650 DEG C, is incubated after 2 hours, is cooled to room temperature with 50 DEG C of speed per hour.
The invention has the beneficial effects as follows: oil pump nozzle rigidity, hardness, wear resistance, fatigue strength and toughness that this technique of the present invention makes are all relatively good.
Embodiment
Technical scheme disclosed by the invention is the production technique of a kind of oil pump nozzle, comprises the steps, 1) and blanking; 2) temperature upsetting; 3) Vehicle Processing; 4) carburizing; 5) quench; 6) tempering; 7) deepfreeze; 8) mill processing; 9) ageing treatment; 10) grind; 11) assemble.
Further, described temperature pier is 400 DEG C ~ 600 DEG C in temperature to carry out temperature pier.
Further, described carburizing refers to and is incubated more than 60 minutes after workpiece is preheated to 925 DEG C, keeps carbon gesture 0.78 ~ 1.24 during this.
Further, described quenching refers to the quenching oil quench cooled that the gear of taking-up is put into 300 DEG C-350 DEG C, continues 0.5 hour, takes out gear air-cooled to room temperature.
Further, described tempering is, after workpiece quenching, reheating 500 ~ 650 DEG C, is incubated after 2 hours, is cooled to room temperature with 50 DEG C of speed per hour.
Oil pump nozzle rigidity, hardness, wear resistance, fatigue strength and toughness that this technique of the present invention makes are all relatively good.
Below the preferred embodiment of the present invention is described in detail.It is to be understood that the those of ordinary skill of this area just can make many modifications and variations according to the design of the present invention without the need to creative work. Therefore, the technical scheme that all technician in the art can be obtained by logical analysis, reasoning, or a limited experiment under this invention's idea on the basis of existing technology, all should by the determined protection domain of claim book.
