Embodiment Construction

[0026] refer to figure 1 , figure 2 and image 3 , the preparation method of a kind of flywheel housing connecting plate of the present invention, comprises the steps:

[0027] a) cutting:

[0028] The No. 45 steel plate that is not easily deformed, easy to obtain, and low in cost is used, and the size, chemical composition, and surface quality of the steel plate are inspected by tape measure, vernier caliper, high-speed carbon-sulfur analyzer, and visual inspection before the process. Then, through the CNC cutting machine, several positioning holes 1 are formed on the steel plate by laser cutting to allow the gears to pass through to obtain cutting blanks, which reduces the possibility of product deformation from the beginning of the process. Cutting parameters are pre-oxygen ≥ 0.5Mp, cutting oxygen ≥ 0.7Mp, acetylene ≥ 0.1Mp, cutting speed 370-390mm / min. The first piece is sent for inspection, and the self-inspection is continued with the imitation cutting comparison sa...

Abstract

The invention discloses a preparation method of a connecting plate of a flywheel housing, comprising a) cutting; b) normalizing: performing normalizing treatment on the cut blank through a heating furnace, firstly keeping the temperature at 880-900°C for 2-3 hours, and then Cool in the furnace for 1.5 to 2.5 hours, and then air cool outside the furnace to obtain a normalized blank; c) shot blasting; d) leveling; e) milling; f) grinding: Grinding the milling blank by a grinding machine surface treatment, and soak in cutting fluid for 20 to 30 minutes after grinding to obtain a ground blank; g) drilling; h) fine grinding: use a grinding machine to perform fine grinding on the perforated blank, and after fine grinding Soak in the cutting fluid for 20-30 minutes to obtain the finely ground blank and i) after-treatment, by using No. Soaked in cooling liquid, the product has good flatness and small deformation, which can not only achieve effective connection between the body and the flywheel housing, but also effectively prevent oil leakage.

Description

【Technical field】 [0001] The invention relates to the technical field of flywheel housings, in particular to the technical field of a preparation method of a flywheel housing connecting plate. 【Background technique】 [0002] With the continuous improvement of diesel engine quality, engine manufacturers and customers pay more and more attention to the appearance of the engine. As an important engine component, the diesel engine flywheel housing is installed between the engine and the gearbox, externally connected to the crankcase, starter and oil pan, and built in the flywheel assembly, which plays the role of connecting the body, protection and carrier. During the long-term operation of the existing engine, oil leakage is prone to occur at the joint surface of the flywheel housing and its connecting plate, and impurities such as dust and mud will be continuously deposited at the position of the oil leakage, thereby reducing the engine's performance. reliability. The study ...
