Embodiment 1

[0038] Example 1, a method for integral spinning of a shock-absorbing shell with cooling fins, the steps are as follows: S1: Laser blanking: use 8-10 mm thick hot-rolled thick steel plates, and the thickness of hot-rolled thick steel plates varies according to the model used , using different thicknesses, and then laser cutting the sheet to obtain a circular sheet, and then blanking to obtain a center hole to form a circular sheet with a center hole 1, such as figure 1 shown in;

[0039]S2: Shoveling inner cylinder: install the upper and lower molds I and two scooping wheels I2 on the CNC spinning machine, that is, the first scooping wheel and the second scooping wheel, and the edge angle radius of the scooping wheel I2 is preferably 2.0 mm, control the rotation speed of the upper and lower mold I to 300-400rpm, use the first scooping wheel and the second scooping wheel to scoop the circular sheet at the same time, form a boss on the circular sheet 1, and control the scooping ...

Abstract

The invention discloses an integral spin-forming method for a damping shell with a cooling fin, and the integral spin-forming method solves the problem that the radiating effect for the damping shellequipped with the cooling fin or welded with the cooling fin is not good. Integral forming and manufacturing production for the damping shell with the cooling fin is accomplished through five processes of laser unloading, inner barrel shoveling and spinning, radiating slot spinning and pressing, outer barrel shoveling and spinning, and machining. Different position layouts, operation sequences andcontrol parameters achieve key effect on whole product processing. The integral spin-forming method adopts spin-forming to realize integral forming and processing of the radiating sheet and the damping shell, mechanical property distribution is uniform, product dynamic balance is good, production quality of the damping shell is improved, the service life of the damping shell is prolonged, marketneeds are met, and a popularization value is relatively high.

Description

technical field [0001] The invention relates to the technical field of shock-absorbing shell processing, in particular to an integral spin forming method of a shock-absorbing shell with cooling fins. Background technique [0002] In order to reduce the torsional vibration of the crankshaft, improve the fatigue life of the crankshaft, and reduce the vibration and noise of the whole vehicle, modern automobiles will install a crankshaft torsional vibration damper at the front end of the crankshaft with the largest torsional vibration amplitude of the engine. According to the different ways of reducing torsional vibration, it can be divided into three types: dynamic type, damping type and composite type, and the crankshaft silicone oil shock absorber belongs to a kind of damping shock absorber. This silicone oil shock absorber requires good sealing and a large inertial body to ensure reliable operation and meet good use requirements. It is suitable for large and medium-sized mar...
