Embodiment Construction

[0026] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] At present, the processing methods for oil rails mainly include hot forging and laser welding. The present invention improves the existing hot forging processing methods and provides a processing method for fuel rail forgings for engines, such as figure 1 As shown, it mainly includes the following steps:

[0028] Ⅰ) Utilize the material cutting equipment to intercept the required blank;

[0029] Ⅱ) Heating the billet so that its surface temperature reaches the hot forging temperature;

[0030] Ⅲ) Carry out the cross wedge rolling process on the billet reaching the hot forging temperature, and process the billet into the prototype of the oil rail forging;

[0031] Ⅳ) Hot forging the prototype of the oil rail forging to make it reach the forging size of the oil rail forging and become a semi-finis...

Abstract

The invention belongs to the technical field of processing engine accessories, and discloses a processing method for an engine oil rail forging, which comprises the following steps: 1) using cutting equipment to cut the required blank; 2) heating the blank to make Its surface temperature reaches the hot forging temperature; Ⅲ) subjecting the billet reaching the hot forging temperature to a cross wedge rolling process, and processing the billet into a prototype of the oil rail forging; Ⅳ) performing hot forging on the prototype of the oil rail forging, Make it reach the forging size of the oil rail forging to become a semi-finished product; V) After hot forging, trim and shape the semi-finished product that meets the forging size to complete the processing of the oil rail forging. The invention adds a cross wedge rolling process before the existing hot forging processing method, improves material utilization rate, reduces processing time, improves production efficiency and increases operating income.

Description

technical field [0001] The invention relates to the technical field of processing engine accessories, in particular to a processing method for an engine oil rail forging. Background technique [0002] As the core component of the engine oil guide system, the oil rail has attracted more and more people's attention on its processing method and material composition. At present, the main processing methods are hot forging and laser welding. When hot forging is used for the production of oil rails, more blanks need to be reserved, and the processing time is relatively long, which causes waste of materials, low production efficiency, and low yield. Low; while laser welding requires relatively advanced manufacturing equipment, which increases production costs. Therefore, it is necessary to make corresponding improvements to the current processing methods to meet market demand. Contents of the invention [0003] The invention provides a processing method for an engine oil rail fo...
