Abstract

The invention discloses a synchronous side forming and side punching method for an automobile lower cross beam part, and belongs to the technical field of automobile lower cross beam part machining. The synchronous side forming and side punching method comprises the following steps that an automobile lower cross beam part die is taken and placed in an ultrasonic cleaning device, and the water temperature is increased for cleaning; according to the drilling process, the polishing process is set inside, the drilling area is polished before drilling, external flaws of the drilling area can be effectively treated, the situation that the flaws affect the drilling process can be effectively avoided, meanwhile, special cooling liquid is configured, the cooling liquid is composed of polyvinyl alcohol butyral, ethyl alcohol and methyl alcohol, and therefore the cooling effect is good. The component materials have excellent heat absorption and heat dissipation effects, the cooling liquid effect of the cooling liquid can be effectively improved, a more excellent protection effect can be provided for a drilling tool, meanwhile, the attaching plate is additionally arranged on the drilling equipment, the attaching plate can be tightly attached to the drilling face, and therefore the situation of drilling deviation caused by shaking during drilling is effectively avoided, and the drilling efficiency is improved. And the drilling precision is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile lower beam parts processing, and in particular relates to a synchronous side forming and side punching method for automobile lower beam parts. Background technique [0002] The car is a means of transportation with multiple wheels. With the improvement of people's living standards, the car has gradually entered the homes of ordinary people. The appearance of the car has greatly shortened the distance between people, and the interior of the car is full of There are tens of thousands of structures, among which the lower beam part of the car is also one of many car parts. [0003] When processing the parts of the lower beam of the automobile, many processing steps are required. Among them, the punching of the parts is one of the most basic and simplest parts processing methods. The current drilling method is not carried out during the implementation process. The injection of coolant will cause da...
