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 as shown,

[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 a whole spinning forming method of a shock absorbing shell with cooling fins, which solves the problem of poor heat dissipation effect of the shock absorbing shells provided with cooling fins or welded cooling fins in the prior art. The present invention completes the integrated manufacturing and production of the shock absorbing shell with cooling fins through five processes of laser blanking, shoveling the inner cylinder, spinning heat dissipation grooves, shoveling the outer cylinder and machining. Among them, different position arrangements, operation sequences and control parameters play a key role in the processing of the entire product. The invention adopts spinning forming to realize the integral molding processing of the heat sink and the shock absorbing shell, the distribution of mechanical properties is uniform, the dynamic balance of the product is good, the production quality of the shock absorbing shell is improved, the service life is prolonged, and the market demand is met. It has high promotional value.

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...
